Illustratively, the interactive smart tablet is installed with multiple types of operating systems, wherein the operating systems include, but are not limited to, an iOS system, an Android system, a Linux system, a Windows system, a UOS system, and the like. In one embodiment, the interactive smart tablet is installed with a Linux system, and the Linux system is installed as a main operating system of the interactive smart tablet in a chip of the interactive smart tablet, which can be understood as a physical CPU. And the interactive intelligent panel is also provided with operating systems such as an Android system, a Windows system, a UOS system and the like, and the operating systems are installed in the Linux system in a mode of virtual operating systems. Generally, a virtual operating system refers to an operating system installed in reliance on virtualization techniques. Virtualization generally refers to that a computing element operates on a virtual basis rather than a real basis, and virtualization technology can enlarge the capacity of hardware and simplify the reconfiguration process of software. When the virtualization technology is applied, the Linux system is used as the Host OS of the interactive intelligent panel. It is understood that in the virtualization technology, an operating system can be installed on a physical machine, and then virtualization software is installed on the operating system, so that a plurality of partitions can be virtualized on the physical machine to install different operating systems respectively, and in this case, the operating system installed on the physical machine is called Host OS. When the interactive intelligent tablet is used as a physical machine, the Host OS is a main operating system which is a Linux system. In one embodiment, each virtual operating system is implemented by a corresponding virtual machine, the virtual machine refers to a complete computer system which has a complete hardware system function and runs in a completely isolated environment through software simulation, and one virtual machine corresponds to one partition in the interactive smart tablet to install the corresponding virtual operating system. Each virtual machine comprises a virtual GPU and a virtual CPU, and the virtual GPU generates and sends pictures in the running process of the virtual operating system, such as a system desktop of the virtual operating system and an application interface of an application program installed in the virtual operating system during running. The virtual CPU implements the running of a virtual operating system. In one embodiment, the Host OS communicates with the Virtual operating systems through a Virtual Machine Manager (VMM) service in the Host OS, wherein the VMM service is a system service of the Host OS for booting and managing the plurality of virtualized systems.
In an embodiment, the interactive smart tablet is described by taking the example that the interactive smart tablet includes the display screen with the touch control function, that is, a user of the interactive smart tablet can control the interactive smart tablet through the display of the touch display screen. At this time, the interactive smart tablet is further equipped with an interactive smart tablet module, and the interactive smart tablet module includes a display screen, a touch control and High Definition Multimedia Interface (HDMI) channel, and other components related to display, touch control, and output. In one embodiment, the VMM service may further perform data communication with the interactive smart tablet module, so that when the display screen receives some touch operations related to the virtual operating system, the interactive smart tablet module notifies the VMM service to respond to the touch operations, so as to implement control over the virtual operating system, such as switching the currently running virtual operating system.
For example, the interactive smart tablet may install at least one application based on each operating system (including the host operating system and the virtual operating system), wherein the functional embodiments that the application can implement are not limited. The application program may be an application program of each operating system, or may be an application program downloaded from a third-party device or a server. In one embodiment, the virtual operating systems are described as examples of installing the application programs, at this time, each virtual operating system installs at least one application program, and an application icon of the installed application program may be displayed on the system desktop of the corresponding virtual operating system. In one embodiment, the Linux system is not installed in a desktop environment, that is, the Linux system always runs in the background, and for a user of the interactive smart tablet, the running interface of the Linux system is not viewed in the display screen. And each virtual operating system has a desktop environment, that is, when a user of the interactive smart tablet uses the virtual operating system, the system desktop of the virtual operating system can be displayed in the display screen.
Fig. 1 is a flowchart of a handover control method according to an embodiment of the present application. Referring to fig. 1, the handover control method specifically includes:
and step 110, receiving a device starting instruction.
The equipment starting instruction is used for starting the interactive intelligent tablet. When the interactive intelligent panel is closed, the interactive intelligent panel can be started through the equipment starting instruction.
And step 120, responding to the equipment starting instruction, starting the interactive intelligent panel and displaying a self-defined starting picture.
And the interactive intelligent panel is started up according to the equipment starting instruction, and starts the Host OS. In one embodiment, during startup, a startup picture is displayed. Illustratively, no graphical interface (i.e., no startup picture) exists in the startup process of the Linux system of the Host OS, and at this time, a customized startup picture can be supported through the plymouth project of the open source, so that the customized startup picture is displayed in the startup process of the interactive intelligent tablet. plymouth is the open source component that starts the screen. The self-defined startup picture can be set according to actual conditions, if the self-defined startup picture is a set logo, at the moment, in the startup process, the interactive intelligent panel displays the logo.
Step 130, after the startup picture is stopped from being displayed, displaying a first interface of the first virtual system, wherein the first interface is a system desktop of the first virtual system, the first interface displays a first application icon of a first application installed in the first virtual system and a second application icon of a second application installed in the second virtual system, and the number of the second virtual systems is at least one.
In one embodiment, during the interactive smart tablet boot process, the VMM services are automatically run, and then all virtual operating systems are booted. And when the default virtual operating system outputs the picture, stopping displaying the current startup picture. The default virtual operating system is a preset virtual operating system, the interactive intelligent tablet displays a system desktop of the default virtual operating system after the interactive intelligent tablet is started, namely, after the interactive intelligent tablet is started, the default virtual operating system is a virtual operating system operated by a foreground, at the moment, the main operating system and the default virtual operating system are both in an operating state, and other virtual operating systems are in a state of suspending the background. Background suspension means that the virtual operating system saves the current state, which is still saved when the virtual operating system is run again. In one embodiment, the default virtual operating system is designated as the first virtual system and the other virtual operating systems are designated as the second virtual system. The number of the second virtual systems can be one or more.
In one embodiment, when it is detected that the first virtual system outputs the screen, the display of the startup screen is stopped, and then the screen of the first virtual system is displayed, where a currently displayed interface of the first virtual system may be marked as a first interface of the first virtual system. Generally, the virtual operating system first displays the corresponding system desktop after being started, and thus the first interface may be the system desktop of the first virtual system.
For example, the first interface displays an application icon of an application installed in the first virtual system, the application installed in the first virtual system may be denoted as a first application, and the application icon of the first application may be denoted as a first application icon. Optionally, the first interface may also display other content, such as displaying application icons of application programs installed in other virtual operating systems. Illustratively, the application program installed in the second virtual system is marked as a second application, and the application graph of the second application is marked as a second application icon.
In one embodiment, the first interface further displays a second application icon for a second application installed in the second virtual system. For example, during the starting process of each virtual operating system, the VMM service may obtain application information of the application program in each virtual operating system, where the application information may include an application icon of the application program and path information of the application program. When the first virtual system displays the first interface, the first virtual system can acquire application information of a second application in the second virtual system through the VMM service, and display a second application icon of the second application in the first interface according to the application information. Optionally, all the second application icons in each second virtual system may be displayed in the first interface, and part of the second application icons in each second virtual system may also be displayed in the first interface. When a part of the second application icon is displayed, the second application icon displayable in the first interface may be previously set in the second virtual system. In one embodiment, the example of displaying a part of the second application icons in each second virtual system in the first interface is described.
In one embodiment, each virtual operating system sets a corresponding icon service, and the icon service may acquire application information of its own virtual operating system and send the application information to the VMM service, and may also acquire application information of other virtual operating systems from the VMM service, so as to display application icons of other virtual operating systems in the system desktop of its own virtual operating system. In one embodiment, when the VMM service runs, a configured shared directory is mounted to each virtual operating system as a file system device. At this time, the icon service of each virtual operating system may write the application information of its own virtual operating system into the shared directory, and may obtain the application information of other virtual operating systems by accessing the shared directory.
Step 140, receiving a first selection instruction, where the first selection instruction is used to select a target application icon from the second application icons.
For example, after the second application icon is displayed in the first interface, the user of the interactive smart tablet may cause the interactive smart tablet to open the second application in the second virtual system by selecting the second application icon in the first interface. In one embodiment, an instruction for selecting the second application icon in the first interface is marked as a first selection instruction, and the second application icon selected by the first selection instruction is marked as a target application icon. Optionally, the user may issue the first selection instruction by touching (e.g., clicking, long-pressing, etc.) the second application icon, or the user may select the second application icon by using an external device (e.g., a mouse, a keyboard, a smart pen, etc.) associated with the interactive smart tablet to issue the first selection instruction.
And 150, responding to the first selection instruction, replacing the first interface with a second interface, wherein the second interface is an application interface displayed after a second application corresponding to the target application icon is started.
Illustratively, the response is performed according to the first selection instruction, in the response process, the interactive smart tablet may determine, according to the target application icon, a second application corresponding to the interactive smart tablet and a second virtual system where the second application is located, then open the second application in the second virtual system, and display an application interface after the second application is opened. In one embodiment, the application interface displayed after the second application is started is recorded as the second interface, and at this time, the displayed first interface is replaced by the second interface.
In one embodiment, when the first selection instruction is received, the first virtual system is a foreground-running virtual operating system, the second virtual system is a background-suspended virtual operating system, when the first selection instruction is responded, the first virtual system needs to be suspended in the background first, the second virtual system is resumed to run, namely, the second virtual system is run in the foreground, the second application corresponding to the target application icon is opened in the second virtual system, so that the second virtual system outputs a second interface of the second application, and then the first interface is replaced by the second interface.
In one embodiment, after receiving a first selection instruction, a first virtual system determines a second virtual system to which a target application icon belongs according to the target application icon selected by the first selection instruction, and then the first virtual system sends the target application icon and the second virtual system to a Host OS, the Host OS suspends the first virtual system in a background, resumes running the second virtual system, and instructs the second virtual system to start a second application corresponding to the target application icon.
In one embodiment, the icon service of the first virtual system sends the target application icon and the second virtual system to the VMM service, and then the VMM service informs the icon service of the second virtual system to start the corresponding second application by the icon service of the second virtual system.
It can be understood that when the first application icon and the second application icon are displayed in the first interface, the user can also select the first application icon, and at this time, the first virtual system directly starts the first application corresponding to the first application icon. After the user selects one application icon in the first interface, the first virtual system confirms whether the selected application icon is the first application icon or the second application icon, if the selected application icon is the first application icon, the first application icon is directly started, and if the selected application icon is the second application icon, the virtual operating system is switched and the corresponding second application is started through the method, and then the corresponding second interface is displayed.
According to the technical means, when the interactive intelligent panel supports multiple operating systems, the technical problems of high equipment cost and high hardware design complexity are solved, the operating systems are installed in the interactive intelligent panel as virtual operating systems by using virtualization technology, corresponding physical CPUs do not need to be configured for each virtual operating system, only physical CPUs of main operating systems need to be configured, and the equipment cost and the hardware design complexity are reduced. Moreover, when the virtualization technology is applied to small-sized devices such as a mobile phone and a tablet computer, the starting speed of an Android system can be accelerated mostly for a single operating system, for example, when the virtualization technology is applied to the Android system, but a plurality of operating systems cannot be applied to the devices. Meanwhile, the system interface of the virtual operating system displays the application icons of the virtual operating system and the application icons of other virtual operating systems, so that the virtual operating systems are switched and the corresponding application programs are opened in a mode of selecting the application icon of another virtual operating system in one virtual operating system, and the rapid switching and starting of the application programs in a plurality of virtual operating systems are realized.
In one embodiment, each virtual operating system is provided with an iocn Server (icon service), and the application icons of the application programs in each virtual operating system can be displayed and managed by communicating with each icon service through the VMM service of the Host OS. Fig. 2 is a first frame diagram of a system according to an embodiment of the present disclosure, and referring to fig. 2, an operating system of an interactive smart tablet includes a Host OS (Linux system) and a plurality of virtual operating systems, where the plurality of virtual operating systems include a Windows system, an Android system, a UOS system, and the like, where the Windows system is implemented by a Windows virtual machine (Windows VM), the Android system is implemented by an Android virtual machine (Android VM), and the UOS system is implemented by a UOS virtual machine (UOS VM).

step 210, receiving a device start instruction.
And step 220, responding to a device starting instruction, starting a main operating system of the interactive intelligent tablet, wherein the main operating system is provided with a first virtual system and a second virtual system, and is an operating system without a desktop environment.
In one embodiment, the Host OS is a Linux system, and the Linux system does not have a desktop environment. The Linux system is provided with a first virtual system and a second virtual system. The first virtual system and the second virtual system comprise a Windows system, an Android system, a UOS system and the like.
And step 230, displaying a self-defined startup picture in the starting process of the main operating system.
In one embodiment, the Linux system supports a custom boot screen through an open-source plymouth project.
And step 240, starting the first virtual system and the second virtual system.
In the boot process of the host operating system, VMM services are automatically run. When the VMM service runs, the first virtual system and the second virtual system are started, at the moment, the interactive intelligent panel also displays a self-defined starting picture, and the first virtual system and the second virtual system are started in a background. In one embodiment, the VMM service sets a background snoop port that can communicate data with each virtual operating system.
In one embodiment, step 240 may include steps 241-243:
step 241, reading the configuration file of the VMM service in the host operating system.
And when the VMM service runs, reading the configuration file of the VMM service according to the running parameters in the initialization stage. The running parameters are parameters in the running process of the main operating system, and the configuration files are configuration parameters and initial settings of VMM services. The specific content of the operating parameters and configuration files can be set according to actual conditions.
And 242, analyzing the configuration parameters of the first virtual system and the second virtual system according to the configuration file.
Normal operation of VMM services may be enabled through the configuration file. In one embodiment, the configuration parameters of each virtual operating system, that is, the configuration parameters of the first virtual system and the second virtual system, may be parsed by the configuration file. In one embodiment, the configuration parameters of the virtual operating system may be configuration parameters of each virtual machine in which the virtual operating system is installed, and each virtual machine may be run through the configuration parameters, thereby implementing running each virtual operating system. Wherein, the content of the configuration parameter can be set according to the actual situation. In one embodiment, the configuration parameters include: a shared directory of the Host OS and the virtual operating system (equivalent to a configured shared directory); the number of virtual machines (corresponding to the number of virtual operating systems), the virtual operating system information of each virtual machine, and a default virtual machine (corresponding to which virtual operating system the first virtual system is identified); peripheral (namely, external equipment) information of the interactive intelligent tablet; a port for communicating each virtual machine with the VMM service (corresponding to a monitoring port for data communication between the VMM service and each virtual operating system); a virtual operating system image path for each virtual machine; configuration parameters of a virtual GPU of each virtual machine; the virtual network configuration parameters and the execution script of each virtual machine are used for managing the virtual network of the virtual operating system; configuration parameters of a virtual CPU of each virtual machine; configuration parameters of a memory of each virtual machine; the boot file information of each virtual machine is used for realizing the boot of the virtual machine; the USB port appointed by each virtual machine can enable the virtual machine to be connected with external USB equipment through the USB port; and (3) the virtual socket ID information of each virtual machine, except the information of the virtual GPU, other information in the virtual machine is communicated based on a universal socket mechanism, and socket communication can be realized through the virtual socket ID.
And 243, starting the first virtual system and the second virtual system according to the configuration parameters.
In one embodiment, after the configuration parameters are analyzed, all the virtual machines are started, that is, the first virtual system and the second virtual system are started.
In one embodiment, when the first virtual system and the second virtual system are started, the method further includes: mounting, by the VMM service, a shared directory configured in the host operating system to the first virtual system and the second virtual system; respectively collecting first application information and second application information by a first icon service and a second icon service, wherein the first application information comprises a first application icon and first path information of a first application, and the second application information comprises a second application icon and second path information of a second application; updating, by the first icon service and the second icon service, the first application information and the second application information to the shared directory, respectively.
For example, when the host operating system is started, the VMM service is automatically run, and the VMM service configures a set shared directory (the shared directory may be determined by a configuration parameter), where the shared directory is used to record application information of an application icon in each virtual operating system, for example, to record the application icon of an application program installed in each virtual operating system and corresponding path information, and the path information is used to describe a path where the application program is located. When each virtual operating system is started, the VMM service mounts the shared directory as a file system device to each virtual operating system (which may also be understood as mounting to each virtual machine). The file system device is a device belonging to a file system (managing and storing file information) in the operating system, and mounting to each virtual operating system means directly using the shared directory by the virtual operating system. In one embodiment, mount to each virtual operating system is done in a VirtFS virtualized file system fashion. The VirtFS is a system level virtualization technology, and the system level virtualization technology can directly deliver a system service interface (equivalent to an interface of a shared directory) of a host (equivalent to an interactive smart tablet) to a virtual machine for use.
Illustratively, the icon service in each virtual operating system is operated as a system service of the virtual operating system during the startup process of the virtual operating system. In one embodiment, the application events that the icon service can handle include application icon collection, which is writing application information of application programs installed in the virtual operating system into the shared directory. Illustratively, when the first icon service runs, the application information of first application icons in the first virtual system is collected, where the application information of the first application icons is recorded as first application information, each first application icon corresponds to one piece of first application information, the first application information includes the first application icon and first path information, and the first path information refers to path information of the first application in the first virtual system. After the first icon service collects the first application information, the first application information may be written to the shared directory. Similarly, when the second icon service runs, collecting application information of a second application icon in a corresponding second virtual system, wherein the application information of the second application icon is recorded as the second application information, each second application icon corresponds to one piece of second application information, the second application information includes the second application icon and second path information, and the second path information refers to path information of the second application in the second virtual system. After the second icon service collects the second application information, the second application information may be written to the shared directory.
In one embodiment, the application events that the icon service can handle further include: the shared directory is updated. Illustratively, when the first application and/or the second application are updated, the first application information and/or the second application information in the shared directory are updated synchronously. For example, when a first application is added to and/or deleted from a first virtual system, the first application installed in the first virtual system changes, that is, the first application is updated, and at this time, the first icon service writes first application information of the newly added first application into the shared directory and/or deletes the first application information of the first application in the shared directory.
Step 250, when the first virtual system outputs the startup picture, stopping displaying the startup picture.
In one embodiment, during the stage when the shared directory is mounted to each virtual operating system, the VMM service may also listen for the virtual GPU of the default virtual operating system (i.e., the first virtual system) to listen for a message that the virtual GPU is ready to send the first virtual system view. When the virtual GPU is ready to send the first virtual system picture, the state of the virtual GPU changes, namely the state changes to the state of an output picture, and at the moment, the VMM service determines to monitor the message that the virtual GPU is ready to send the first virtual system picture.
When the first virtual system is ready to send the first virtual system picture, the first virtual system outputs the corresponding picture. In one embodiment, after the first virtual system is started, the first output picture is a start picture in the starting process of the first virtual system. The start-up screen may be a screen of a preset setting in the first virtual system. And when the VMM service determines that the message that the virtual GPU is ready to send the first virtual system picture is monitored, stopping displaying the startup picture in a plymouth service mode.
Step 260, after the startup picture stops displaying, displaying the startup picture of the first virtual system, and suspending the second virtual system in the background.
And after the display of the starting-up picture is stopped, displaying a starting picture output by the virtual GPU of the first virtual system. And taking the first virtual system as a virtual operating system running in the foreground, and sending a suspension command to the second virtual system so as to suspend the second virtual system in the background, namely suspending the second virtual system to run.
In one embodiment, when each virtual operating system runs, in order to optimize the running efficiency of the virtual operating system, the VMM service may send an inquiry command to the virtual CPU of each virtual operating system, and the virtual CPU may return the process and ID information of the virtual CPU according to the inquiry command, so that the VMM service may clarify the running condition of the virtual operating system through the process and ID information of the virtual CPU. The process of the virtual CPU refers to each process currently running in the virtual CPU. The VMM service may bind each virtual CPU to a physical CPU of the interactive smart tablet through a taskset command, where the physical CPU may be considered as a processor installed in the interactive smart tablet, which is installed with a Linux system. the taskset command is a command used for viewing and setting the use condition of the physical CPU core in the Linux system.
Step 270, starting a VMM message management service in the VMM service, where the VMM service is a service provided by the host operating system, and the VMM message management service drives the management and operation of the first virtual system and the second virtual system.
The VMM message management service drives the management and execution of the virtual operating system through messages. In one embodiment, the VMM service may contain a plurality of message threads, wherein the plurality of message threads includes at least a virtual machine message thread, an application message thread, a virtual machine screen state message thread, and a USB peripheral message thread. The virtual machine message thread may monitor a port of each virtual machine in the configuration parameters, which communicates with the VMM service, so as to implement the following types of message communication between the VMM service and each virtual operating system: adding and deleting message communication of the USB peripheral of the virtual operating system; adding and deleting message communication of touch equipment (equipment for realizing touch control in a display screen) of a virtual operating system; suspending, resuming message communication of running the virtual operating system and inquiring the state of the virtual operating system; switching and displaying message communication of the virtual operating system; message communication binding a virtual CPU of a virtual operating system to a physical CPU. The application message linearity can monitor the virtual socket ID of each virtual machine in the configuration parameters to implement the following types of message communication between the VMM service and each virtual operating system: and opening the message communication of the application program selected by the user in the virtual operating system suspended in the background. And the virtual machine picture state message thread monitors the state of the virtual GPU of each virtual operating system so as to judge whether the switching is finished or not through the state of the virtual GPU when the virtual operating systems are switched. The state of the virtual GPU refers to whether the virtual GPU is ready to output a picture. And monitoring hot plug messages of all the USB peripherals of the interactive intelligent tablet by the USB peripheral message thread, wherein the USB peripherals are external equipment connected to the interactive intelligent tablet in a USB mode. Hot plug refers to plugging or unplugging without turning off the power supply. When a USB peripheral carries out hot plug, a USB peripheral message thread can send a USB hot plug message to the VMM service, and the VMM service converts the message into a corresponding USB peripheral message and sends the USB peripheral message to a corresponding virtual operating system, so that the virtual operating system can determine the hot plug condition of the USB peripheral. In one embodiment, messages communicated by processes in the VMM message management service may be divided into two categories: one type is a message communicated in a virtual machine picture state message thread when the virtual GPU state is monitored, and the message adopts a euvnet message mechanism based on Linux kernel; one type is other messages except the above, namely messages communicated in a virtual machine message thread, an application message thread and a USB peripheral message thread, the messages adopt a general socket mechanism, and optionally, the format of the messages is as follows: { message header } { message type } { separator } { message parameter } { message tail }, where the message header indicates a message start, the message tail indicates a message end, and the separator is used to distinguish a message type and a message parameter, the message type refers to a message type communicated in the above-mentioned virtual machine message thread, application message thread, and USB peripheral message thread, and the message types may be divided into a message with parameters and a message without parameters according to the message parameters. Wherein, for the message without parameters, the message parameters in the message format are null. For the message with parameters, the corresponding parameters are written in the message parameters in the message format. For example, when a second virtual system with a message type of background suspension opens a certain second application, the related content of the second virtual system and the related content of the second application must be written in the message parameter.
Fig. 4 is a VMM service operation flow chart provided in an embodiment of the present application, and referring to fig. 4, based on steps 240 to 270, in the process of starting the Linux system, the VMM service is operated, and during the operation, the VMM service first goes through an initialization stage (that is, the VMM configuration file is read according to the operation parameter), then the configuration parameter of each virtual operating system is analyzed, then each virtual operating system is started according to the configuration parameter (which is equivalent to starting each virtual machine), and then when the first virtual system outputs a startup animation, a startup screen of the first virtual system is displayed, and the VMM message management service is started.
Step 280, after the start picture is stopped from being displayed, a first interface of the first virtual system is displayed, the first interface is a system desktop of the first virtual system, the first interface displays a first application icon of a first application installed in the first virtual system and a second application icon of a second application installed in the second virtual system, and the number of the second virtual system is at least one.
Illustratively, after the first virtual system is started, the display of the corresponding start screen is stopped, and the system desktop of the first virtual system is displayed, that is, the first interface is displayed.
In one embodiment, when the first application information and the second application information are written in the shared directory, displaying the first interface of the first virtual system includes steps 281 to 282:
step 281, reading the second application information recorded in the shared directory by the first icon service.
For example, after the first virtual system is started, the first icon service reads, in the shared directory, second application information corresponding to all the second virtual systems in the background according to the first application information and the second application information, that is, the first icon service reads all the second application information.
Step 282, displaying, by the first icon service, the second application icon in the first interface according to the second application information.
For example, the corresponding second application icon is determined according to the second application information, and the second application icon is displayed in the first interface, at this time, each first application icon and each second application icon are displayed in the first interface. The sorting rules of the first application icon and the second application icon can be set according to actual conditions. For example, fig. 5 is a schematic view of a first interface according to an embodiment of the present application, and with reference to fig. 5, a Windows system is taken as a first virtual system, and an Android system and a UOS system are taken as a second virtual system for description, at this time, in the first interface, application icons of the Windows system, application icons of the Android system, and application icons of the UOS system are sequentially displayed in an array.
Step 290, receiving a first selection instruction, where the first selection instruction is used to select a target application icon from the second application icons.
For example, when the first virtual system detects that a certain second application icon is selected by the user, it is determined that the first selection instruction is received.
Step 2100, generating a switching message by the first icon service according to the first selection instruction, where the switching message includes the target application icon and the second virtual system to which the target application icon belongs.
The application events that the icon service can handle further include: the icon service may send the associated message (i.e., the switch message) to the application message thread of the VMM message management service when the user thinks to open the application program of the virtual operating system in the background, for example. For example, after receiving the first selection instruction, the first icon service determines the selected target application icon and the second virtual system to which the target application icon belongs, optionally, the second virtual system to which the target application icon belongs may be specified according to the second application information of the target application icon, and then, the target application icon and the second virtual system to which the target application icon belongs are written into a message, where the message written into the target application icon and the second virtual system to which the target application icon belongs is recorded as a switching message.
Step 2110, sending the switching message to the VMM message management service by the first icon service.
Illustratively, the first icon service sends the switch message to the VMM message management service, specifically to an application message thread of the VMM message management service.
And step 2120, according to the switching message, the VMM message management service notifies a second icon service of a second virtual system to which the target application icon belongs to start a second application corresponding to the target application icon.
For example, after receiving the switching message, the application message thread of the VMM message management service notifies the corresponding second icon service of the second virtual system according to the switching message, that is, the application message thread sends a message for opening the second application corresponding to the target application icon to the second icon service, and the second icon service opens the second application according to the message of the application message thread.
In one embodiment, step 2120 includes steps 2121-2126:
and 2121, according to the switching message, the VMM message management service instructs to delete the touch device of the first virtual system.
The touch device refers to a device for implementing touch operation, for example, the touch device is a touch detection device and a touch chip installed in a display screen and related to touch operation, for example, the display screen may be one or more of an infrared touch screen, an electromagnetic touch screen, and a capacitive touch screen, when the display screen is the infrared touch screen, the touch detection device is an infrared touch frame, the touch chip is connected to the infrared touch frame, when a user touches the display screen, the infrared touch frame detects a touch action, and the touch chip determines a touch position and a touch time according to the touch action detected by the infrared touch frame, so as to implement detection of touch operation. For example, when the foreground of the first virtual system runs, the touch device in the display screen belongs to the touch device of the first virtual system, and at this time, the touch operation detected by the touch device may be regarded as an operation performed on the first virtual system.
After receiving the switching message, the application message thread of the VMM message management service sends a message for deleting the touch device to the first virtual system, and then the first virtual system deletes the touch device of the first virtual system after receiving the message.
Step 2122, the VMM message management service instructs to delete the USB device of the first virtual system.
The USB device of the first virtual system refers to a USB peripheral of the first virtual system, that is, a USB peripheral available for the first virtual system.
For example, after deleting the touch device of the first virtual system, the virtual machine message thread of the VMM message management service sends a message for deleting the USB peripheral device to the first virtual system, and then, after receiving the message, the first virtual system deletes the USB device of the first virtual system, where the operation received by the USB device is unrelated to the first virtual system.
Step 2123, the VMM message management service instructs the background to suspend the first virtual system.
Illustratively, after deleting the USB device of the first virtual system, the virtual machine message thread of the VMM message management service sends a message of suspending in the background to the first virtual system, and then the first virtual system receives the message and suspends in the background, at which time the first virtual system stops running in the foreground.
And step 2124, the VMM message management service indicates that the second virtual system to which the running target application icon belongs is recovered.
Illustratively, after a first virtual system is suspended in a background, a virtual machine message thread of the VMM message management service sends a message for resuming running to a second virtual system corresponding to the target application icon, and then, after receiving the message, the second virtual system runs in a foreground, and the state of the second virtual system during running is the same as the state of the second virtual system during suspension, at this time, the second virtual system runs in the foreground, so as to implement switching of virtual operating systems. Optionally, the second icon service operates when the second virtual system runs in the foreground, the second icon service may read the first application information in the shared directory and the second application information of the other second virtual systems, and display the first application icon corresponding to the first application information and the second application icon corresponding to the second application information in the system desktop of the second virtual system according to the read content, that is, the system desktop of the second virtual system displays the application icons of the application programs installed in the other virtual operating systems in addition to the application icon of the application program installed in the system desktop of the second virtual system.
Step 2125, instructing, by the VMM message management service, the second virtual system to add the touch device.
For example, after the second virtual system is operated in the foreground, the virtual machine message thread of the VMM message management service sends a message for adding the touch device to the second virtual system, and then, after the second virtual system receives the message, the touch device is added, for example, the touch device deleted by the first virtual system is added to the second virtual system, at this time, the touch operation received by the touch device is the touch operation for controlling the second virtual system.
And step 2126, the VMM message management service notifies the second icon service of the second virtual system to start the second application corresponding to the target application icon.
After the touch device is added, the application message thread of the VMM message management service sends a message of opening the second application of the target application icon to the second icon service of the second virtual system to inform the second icon service of opening the second application of the target application icon.
And step 2130, starting a second application corresponding to the target application icon by the second icon service.
Illustratively, after receiving the message sent by the application message thread, the second icon service opens the second application according to the message. For example, fig. 6 is a flowchart for starting an application according to an embodiment of the present application, and referring to fig. 6, an application message thread of the vmm message management service sends a message for opening a second application of a target application icon to a second icon service of a second virtual system through a virtual socket, and after the second icon service receives the message, the second application is opened through an interface of the second application corresponding to the target application icon in the second virtual system, so as to start the second application in the second virtual system.
Step 2140, the VMM service obtains a second interface of the second application, and changes the first interface to the second interface.
For example, after the second application is started, the VMM service acquires a picture output by the virtual GPU in the second virtual system, that is, acquires the second interface, and changes the first interface in the display screen to the second interface. At this time, the virtual machine screen state message thread of the VMM message management service may determine whether the switching is successful by monitoring the virtual GPU state of the second virtual system.
In one embodiment, after replacing the first interface with the second interface, the method further includes: the second virtual system is instructed by the VMM message management service to add a USB device. For example, after the second interface is displayed, the virtual machine message thread of the VMM message management service sends a message of adding the USB device to the second virtual system, and then, after the second virtual system receives the message, the USB device of the second virtual system is added, for example, the USB device deleted by the first virtual system is added to the second virtual system, and at this time, the USB device is available for the second virtual system.
Fig. 7 is a flowchart of application switching according to an embodiment of the present application. Referring to fig. 7, after receiving the switching message, the vmm message management service deletes the touch device of the first virtual system (foreground operation) first, then deletes the USB device of the first virtual system, then suspends the first virtual system, resumes the operation of the second virtual system, instructs the second virtual system to add the touch device, then notifies the second virtual system to open the second application corresponding to the target application icon, switches the first interface to the second interface, and then adds the USB device to the second virtual system, so as to implement switching the first virtual system to the second virtual system and starting the second application corresponding to the target application icon in the second virtual system.
On the basis, referring to fig. 8, when implementing application switching across virtual operating systems, the VMM service first goes through an initialization stage (i.e., reads a VMM configuration file according to an operating parameter), then starts each virtual operating system (a first virtual system and a second virtual system) according to a configuration parameter analyzed by the VMM configuration file, and then mounts a shared directory to each virtual operating system. After that, each application information (including the application icon and the path information) is written in the shared directory by the icon service of each virtual operating system. After starting each virtual operating system according to the configuration parameters analyzed by the VMM configuration file, operating a VMM message management service to monitor virtual machine messages (realized by a virtual machine message thread), application messages (realized by an application message thread), display system messages (realized by a virtual machine picture state message thread) and USB equipment messages (realized by a USB peripheral message thread), wherein when monitoring the application messages, switching the current virtual operating system to the virtual operating system to which the target application icon belongs can be realized according to a selection instruction for selecting the target application icon, and then opening an application program corresponding to the target application icon.
Step 2150, receive the application exit instruction.
Illustratively, the application exit instruction is an instruction to exit a second application that is currently open. Optionally, when detecting that the second application is closed or running in the background, the second virtual system determines that the application quit instruction is received. Optionally, the user may send an application exit instruction by touching the display screen or operating the USB device.
Step 2160, in response to the application quitting instruction, quitting the second application corresponding to the target application icon, and replacing the second interface with a third interface, where the third interface is a system desktop of a second virtual system to which the second application belongs, and the third interface displays a first application icon of the first virtual system and a second application icon of the second virtual system.
Illustratively, the second virtual system exits the second application after receiving the application exit instruction, and it is understood that, when the application exit instruction is used to close the second application, exiting the second application refers to closing the second application, and when the application exit instruction is used to execute the second application in the background, exiting the second application refers to switching the second application to the background operation.
In one embodiment, the application interface of the second application is no longer displayed in the display screen when the second application is exited. At this time, the display screen is switched from the second interface to a third interface, in one embodiment, the third interface is a system desktop of the second virtual system, and when the second virtual system resumes running, the second icon service of the second virtual system realizes that the first application icon corresponding to the first application information and the second application icons corresponding to the second application information of other second virtual operating systems are displayed in the system desktop of the second virtual system in a manner of reading the shared directory, that is, the system desktop of the second virtual system displays the application icons of the application programs installed in the second virtual operating system in addition to the application icon of the application program installed in the system desktop of the second virtual system. Therefore, when the system desktop of the second virtual system is displayed, a first application icon of a first application installed in the first virtual system and a second application icon of a second application installed in the second virtual system are displayed in the system desktop. In this case, the user can start the application program of the other virtual operating system by selecting the application icon of the other virtual operating system.
The method includes the steps of starting a host operating system of the interactive smart tablet by receiving a device starting instruction, displaying a self-defined starting picture, then starting a first virtual system and a second virtual system, stopping displaying the starting picture when the first virtual system outputs the starting picture, displaying the starting picture, suspending the second virtual system in a background, then starting a VMM message management service, and after the starting picture stops displaying, displaying a first interface of the first virtual system, displaying a first application icon of the first virtual system and a second application icon of the second virtual system on the first interface, receiving a first selection instruction for selecting the second application icon, generating a switching message by the first icon service according to the first selection instruction and sending the switching message to the VMM message management service, notifying the second icon service of the second virtual system to which the target application icon belongs to start a second application corresponding to the target application icon by the VMM message management service, so that the second icon service starts the second application, replacing the first interface with a technical means of the second interface, solving the technical means of supporting multiple intelligent tablet devices, only needing to design of high-cost virtual operating systems and using high-cost of the CPU. Multiple virtual operating systems can be managed and operated through VMM service and icon service of each virtual operating system, each virtual operating system can share own application information through a sharing directory, so that application icons of all virtual operating systems are displayed in a system desktop of each virtual operating system, and further, the application program is switched and started quickly. When the virtual operating system is switched, the processing of the touch equipment is prior to the processing of the USB equipment, so that the loading time of the touch equipment for realizing the touch function when the virtual operating system is switched can be optimized. The second application of the target application icon is opened before the virtual GPU is displayed to output the picture, the second interface displayed at the first time can be used as the application interface of the second application after the second application is opened, the system desktop of the second virtual system cannot be displayed, and the use experience of a user when the application is switched is improved.
In one embodiment, switching the virtual operating system may also be implemented by the interactive smart tablet module and VMM services of the interactive smart tablet. Illustratively, the interactive smart tablet module provides a "channel management, screen sound setup system" that may be used to manage various components related to setting up display, touch, output, etc., which may communicate with VMM services to enable switching virtual operating systems. Fig. 9 is a second frame diagram of the system according to an embodiment of the present application, and referring to fig. 9, a PC module of an interactive smart tablet refers to a module in which a Host OS is located, a Host OS in the PC module is a Linux system, and a plurality of virtual operating systems include a Windows system, an Android system, and a UOS system, where the Windows system is implemented by a Windows virtual machine, the Android system is implemented by an Android virtual machine, and the UOS system is implemented by a UOS virtual machine. An interactive smart tablet module of an interactive smart tablet provides a "channel management, screen sound setting system", a "channel management, screen sound setting system" to communicate with a VMM service in a Host OS, and the VMM service communicates with each virtual operating system to implement switching of each virtual operating system based on the interactive smart tablet module, and fig. 10 is a flowchart of another switching control method provided in an embodiment of the present application. The handover control method shown in fig. 10 is applied to the framework shown in fig. 9.
Referring to fig. 10, when switching from one virtual operating system to another virtual operating system, the switching control method includes:
step 310, receiving a device starting instruction;
and step 320, responding to the equipment starting instruction, starting the interactive intelligent panel and displaying a self-defined starting picture.
And responding to a device starting instruction, starting a main operating system of the interactive intelligent tablet, and displaying a self-defined starting picture in the starting process of the main operating system. This step can be referred to the relevant description in step 120 and step 230. In the boot process of the host operating system, VMM services are automatically run. Starting a first virtual system and a second virtual system when the VMM service runs, wherein the starting of the first virtual system and the second virtual system comprises the following steps: reading a configuration file of VMM service in a Host operating system, analyzing configuration parameters of a first virtual system and a second virtual system according to the configuration file, and analyzing configuration parameters of the first virtual system and the second virtual system according to the configuration file, wherein the process can refer to the related description of the step 241-the step 243, and needs to be explained. In one embodiment, the VMM service is provided with a background listening port (i.e., a port in the configuration parameters) for communicating with the "channel management, screen sound setup system" in the interactive smart tablet. Compared with step 243, in this step, when the first virtual system and the second virtual system are started, the shared directory does not need to be configured and mounted.
In one embodiment, after the interactive smart tablet is started and the customized booting screen is displayed, the method further includes: sending a query instruction to the first virtual system and the second virtual system through VMM service by the display screen component so as to acquire a first system icon of the first virtual system and a second system icon of the second virtual system through the query instruction; adding, by the display screen component, the first system icon and the second system icon in the virtual control area.
Illustratively, the display screen component refers to an interactive smart tablet module. And the interactive intelligent panel module sends a query instruction to the VMM service, and then the VMM service queries the first virtual system and the second virtual system, namely the VMM service sends the query instruction to the first virtual system and the second virtual system. The inquiry instruction can acquire system messages of the first virtual system and the second virtual system, each virtual operating system corresponds to one system message, the content of the system messages can be set according to actual conditions, and the type of the currently started virtual operating system can be determined through the system messages. In one embodiment, the system message at least includes a system icon, where the system icon refers to an icon representing a corresponding virtual operating system, for example, when the virtual operating system is an Android system, the corresponding system icon is an icon displaying the Android system. And recording the system icon of the second virtual system as a second system icon, and recording the system icon of the first virtual system as a first system icon. And then, the VMM service enables the interactive intelligent panel module to acquire the first system icon and the second system icon through the VMM service, and then, the interactive intelligent panel module displays the first system icon and the second system icon through the channel management and screen sound setting system. In one embodiment, the interactive intelligent tablet module 'channel management and screen sound setting system' provides a graphical setting interface, the graphical setting interface is marked as a virtual control area, and the size and the display position of the virtual control area can be set according to actual conditions. In one embodiment, the virtual control area may be displayed and hidden in the display screen in a set touch interaction manner, and it can be understood that the virtual control area is an interface generated by the interactive smart tablet module, but not an interface output by the virtual operating system, and the first system icon and the second system icon are displayed in the virtual control area.
And step 330, after the display of the startup picture is stopped, displaying a first interface of the first virtual system, wherein the first interface is a system desktop of the first virtual system.
When the first virtual system outputs a startup picture, the startup picture is stopped to be displayed, after the startup picture is stopped to be displayed, the startup picture of the first virtual system is displayed, the second virtual system is hung on the background, and after the startup picture is stopped to be displayed, the first interface of the first virtual system is displayed. The process can refer to the relevant description in steps 250, 260 and 280. Optionally, since switching of the application is not currently involved, only the first application icon of the first virtual system may be displayed in the first interface.
In one embodiment, a start screen of the first virtual system is displayed, and after the second virtual system is suspended in the background, the VMM message management service in the VMM service may be started, where, compared to the VMM message management service in step 270, the VMM message management service in this step reserves a virtual machine message thread, a virtual machine screen state message thread, and a USB peripheral message thread, and, instead of reserving an application message thread, adds an interactive smart panel module message thread, and the interactive smart panel module message thread may monitor a port of the VMM service in the configuration parameters, where the VMM service communicates with the interactive smart panel module, so as to implement the following types of message communication between the VMM service and the interactive smart panel module: inquiring all message communication of the virtual operating systems; inquiring message communication of a currently running virtual operating system; message communication for inquiring the running states of all the virtual operating systems; switching message communication of the virtual operating system; a message communication querying the IP address of the Host OS. It can be understood that the interactive smart tablet module may send a query instruction to the VMM service through the interactive smart tablet module message thread to obtain information of all virtual operating systems, and display a corresponding system icon in the virtual control region according to the information of the virtual operating systems.
It can be understood that the messages communicated by each process in the VMM message management service may also be divided into two types, which are the same as the two types of messages described in step 270 and are not described herein again. For example, when the message type is a query command for all virtual operating systems, the message parameter is null, and when the message type is a query command for a specified virtual operating system, the relevant content of the specified virtual operating system is written in the message parameter. When the message type is the switching virtual operating system, the relevant content of the virtual operating system to be switched to (in the embodiment, the second virtual system corresponding to the second selection instruction) is written in the message parameter. At this time, the operation flowchart of the VMM service may refer to fig. 4.
And step 340, receiving a screen control instruction.
Illustratively, the screen control instructions are used to bring up the virtual control area. The screen control instruction may be triggered by a preset touch interaction mode, for example, the preset touch interaction mode is a touch operation stroking upwards from the bottom of the display screen, and when the touch operation is detected, it is determined that the screen control instruction is received. In one embodiment, the screen control command is detected by the interactive smart tablet module.
Step 350, responding to the screen control instruction, displaying a virtual control area in the first interface, wherein a first system icon of the first virtual system and a second system icon of the second virtual system are displayed in the virtual control area.
In one embodiment, the virtual control area is evoked in the display screen in response to the screen control command, i.e. the virtual control area is displayed in the first interface. It should be noted that, after each virtual operating system is started, the interactive smart tablet module may obtain the first system icon and the second system icon through the query instruction, and the first system icon and the second system icon are displayed in the virtual control area by the "channel management and screen sound setting system" of the interactive smart tablet module, so that when the virtual control area is called, the first system icon and the second system icon are displayed in the virtual control area.
It is understood that the virtual control area is provided by a display screen component of the interactive smart tablet. Illustratively, the virtual control area is provided by a "channel management, screen sound setup system" in the interactive smart tablet module.
The virtual control area may display icons related to display settings, sound settings, HDMI channels, and the like, in addition to the system icons, so that when a user selects a certain icon, the corresponding setting is performed. In an embodiment, fig. 11 is a schematic view of a virtual control area according to an embodiment of the present application, and referring to fig. 11, a virtual operating system includes a Windows system, an Android system, and a UOS system, and system icons of the Windows system, the Android system, and the UOS system are displayed in the virtual control area, and contents such as display settings, sound settings, and HDMI are also displayed. It will be appreciated that for a virtual operating system running in the foreground, the corresponding system icon may be highlighted in the virtual control area, such as by highlighting. For example, the first virtual system is operated in the foreground, and the first virtual system is a Windows system, so the system icon of the Windows system is highlighted in the virtual control area.
And step 360, receiving a second selection instruction, wherein the second selection instruction is used for selecting the target system icon from the second system icons.
For example, after the virtual control area is displayed in the first interface, the user of the interactive smart tablet may enable the interactive smart tablet to open the second virtual system corresponding to the second system icon by selecting the second system icon in the virtual control area. In one embodiment, an instruction for selecting the second system icon in the virtual control area is recorded as a second selection instruction, and the second system icon selected by the second selection instruction is recorded as a target system icon. The user may issue the second selection instruction by touching (e.g., clicking, long-pressing, etc.) the second system icon.
In one embodiment, receiving the second selection instruction includes steps 361-362:
and 361, generating a second selection instruction by the display screen component according to the touch operation acted on the second system icon.
For example, when the user touches the second system icon, the display screen component (interactive smart tablet module) may detect the touch operation of the user, and generate a second selection instruction when it is determined that the touch operation is a touch operation for selecting the second system icon.
Step 362, the VMM message management service serviced by the VMM receives the second selection instruction sent by the display screen component.
Illustratively, after the display screen component generates a second selection instruction, the second selection instruction is sent to the message thread of the interactive smart tablet module of the VMM message management service, and then the message thread of the interactive smart tablet module determines that the message type is the virtual operating system display switching according to the second selection instruction, and performs a corresponding response.
And 370, responding to the second selection instruction, replacing the first interface with a fourth interface, wherein the fourth interface is the system desktop of the second virtual system corresponding to the target system icon.
Illustratively, when determining that the display of the virtual operating system is switched, the VMM message management service instructs the first virtual system to suspend in the background, and resumes running the second virtual system corresponding to the target system icon as the virtual operating system running in the foreground, at this time, obtains and displays the image output by the virtual GPU in the second virtual system, and switches the first interface. It should be noted that, when the second virtual system resumes running, the image output by the GPU is the system desktop of the second virtual system, and the fourth interface is the system desktop of the second virtual system. Since the switching of the application program is not currently involved, only the second application icon of the second virtual system may be displayed in the system interface of the second virtual system. In practical application, when the background of the second virtual system is suspended, an application interface of a certain second application is displayed, and then, when the second virtual system is resumed to run, the application interface can be displayed.
And after the virtual control area is switched to the second virtual system, highlighting a second system icon of the second virtual system in the virtual control area.
In one embodiment, replacing the first interface with the fourth interface in response to the second selection instruction includes steps 371-377:
step 371, in response to the second selection instruction, instructing, by the VMM message management service, to delete the touch device of the first virtual system.
After receiving the second selection instruction, the interactive smart tablet module message thread of the VMM message management service sends a message for deleting the touch device to the first virtual system, and then the first virtual system deletes the touch device of the first virtual system after receiving the message, at this time, the touch operation received by the touch device is irrelevant to the first virtual system.
Step 372, the VMM message management service instructs to delete the USB device of the first virtual system.
For example, after deleting the touch device of the first virtual system, the virtual machine message thread of the VMM message management service sends a message for deleting the USB peripheral device to the first virtual system, and then, after receiving the message, the first virtual system deletes the USB device of the first virtual system, where the operation received by the USB device is unrelated to the first virtual system.
Step 373, the VMM message management service instructs the background to suspend the first virtual system.
Illustratively, after deleting the USB device of the first virtual system, the virtual machine message thread of the VMM message management service sends a message of suspending in the background to the first virtual system, and then the first virtual system receives the message and suspends in the background, at which time the first virtual system stops running in the foreground.
And step 374, indicating to restore the second virtual system corresponding to the operating target system icon by the VMM message management service.
Illustratively, after a first virtual system is suspended in a background, a virtual machine message thread of the VMM message management service sends a message for resuming operation to a second virtual system corresponding to the target system icon, and then, after receiving the message, the second virtual system operates in a foreground, and the state of the second virtual system during operation is the same as the state of the second virtual system during suspension, at this time, the second virtual system operates in the foreground, so as to implement switching of virtual operating systems.
Step 375, instruct the second virtual system to add the touch device by the VMM message management service.
For example, after the second virtual system is run in the foreground, the virtual machine message thread of the VMM message management service sends a message of adding the touch device to the second virtual system, and then, after the second virtual system receives the message, the touch device is added, for example, the touch device deleted by the first virtual system is added to the second virtual system, and at this time, the touch operation received by the touch device is the touch operation controlling the second virtual system.
Step 376, the VMM obtains the fourth interface of the second virtual system and replaces the first interface with the fourth interface.
For example, the VMM service obtains a virtual GPU output screen (in the embodiment, the fourth interface) of the second virtual system, and sends the virtual GPU output screen to the display screen for displaying, at this time, the virtual machine screen state message thread of the VMM message management service may determine whether the switching is successful by monitoring the virtual GPU state of the second virtual system.
Step 377, add USB device for the second virtual system by VMM message management service.
After the fourth interface is displayed, the virtual machine message thread of the VMM message management service sends a message of adding the USB device to the second virtual system, and then, after the second virtual system receives the message, the USB device of the second virtual system is added, for example, the touch device deleted by the first virtual system is added to the second virtual system, and at this time, the USB device may be used by the second virtual system.
Fig. 12 is a flowchart illustrating a virtual operating system switching according to an embodiment of the present application. Referring to fig. 12, after receiving the second selection instruction, the vmm message management service deletes the touch device of the first virtual system (foreground operation) and then deletes the USB device of the first virtual system, suspends the first virtual system, resumes the operation of the second virtual system, instructs the second virtual system to add the touch device, switches the first interface to the fourth interface, and then adds the USB device to the second virtual system, so as to implement switching the first virtual system to the second virtual system.
On the basis, referring to fig. 13, when switching virtual operating systems is implemented, the VMM service first goes through an initialization stage (that is, reads a VMM configuration file according to an operation parameter), then starts each virtual operating system (a first virtual system and a second virtual system) according to the configuration parameter analyzed by the VMM configuration file, and then runs a VMM message management service to monitor a virtual machine message (implemented by a virtual machine message thread), an interactive smart panel message (implemented by an interactive smart panel module message thread), a display system message (implemented by a virtual machine picture state message thread), and a USB monitoring device message (implemented by a USB peripheral device message thread), where, when monitoring the interactive smart panel message, switching a current virtual operating system to a virtual operating system to which a target system icon belongs may be implemented according to a selection instruction for selecting the target system icon.
The method comprises the steps of starting the interactive intelligent panel and displaying a self-defined starting picture by receiving a device starting instruction, displaying a first interface of a first virtual system after the starting picture is stopped from being displayed, then displaying a virtual control area containing a first system icon and a second system icon in the first interface according to a received screen control instruction, receiving a second selection instruction for selecting the second system icon, and replacing the first interface with a fourth interface corresponding to a second virtual system according to the second selection instruction. Multiple virtual operating systems can be managed and operated through the VMM service and the interactive intelligent flat panel module, and therefore the virtual operating systems can be switched and started quickly. When the virtual operating system is switched, the processing of the touch equipment is prior to the processing of the USB equipment, so that the loading time of the touch equipment for realizing the touch function when the virtual operating system is switched can be optimized, and the use experience of a user when the user switches the application is improved.
