For example, the operating device of the intelligent interactive tablet may be a cell phone, an industrial control computer, or the like.
For easy understanding, in the embodiment, the intelligent interaction panel is taken as an actual carrier, and detailed processes of sharing process triggering, sharing target selection and sharing data transmission when the screen sharing method of the intelligent interaction panel is implemented are exemplarily described. The intelligent interaction panel can be integrated equipment for controlling the content displayed on the display panel and realizing man-machine interaction operation through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, sound equipment, a television, a video conference terminal and the like.
Generally, the smart interactive tablet includes at least one display screen. For example, the smart interactive tablet is configured with a display screen having a touch function, and the display screen may be a capacitive screen, a resistive screen, or an electromagnetic screen. In this embodiment, an intelligent interaction panel is provided, and further, a user can realize touch operation by touching a display screen with a finger or a touch pen, and accordingly, the intelligent interaction panel detects a touch position and responds according to the touch position to realize a touch function. Typically, the intelligent interactive tablet is installed with at least one operating system, wherein the operating system includes, but is not limited to, an android system, a Linux system, and a Windows system. Further, the intelligent interactive tablet may install at least one application program having a writing function. The application program can be an application program of an operating system, and meanwhile, the application program downloaded from a third party device or a server is also installed. Optionally, the application program has other editing functions besides writing functions, such as form insertion, picture insertion, figure insertion, form drawing, figure drawing, and the like. Wherein, the drawn table or graph is a computer drawing standard element. A computer drawing standard element may be understood as a printed standard element drawn by an intelligent interactive tablet, which is distinguished from an element written by a user.
The touch screen configured by the intelligent handwriting equipment such as an electronic whiteboard, an electronic blackboard, a digital tablet, an intelligent conference tablet and the like is provided with a writing area for displaying input contents in response to writing operation of a user, when the writing area is used for writing, for example, when a touch pen or a finger is contacted with the touch screen, the touch screen can sense current change, voltage change or magnetic flux change (corresponding to specific setting types of the capacitive touch screen, the resistive touch screen or the electromagnetic touch screen), a touch signal containing coordinates of a touch position and triggering time of the touch signal are obtained, track data of a writing track input in the process of lifting and writing each time the touch pen or the finger of the user is pressed down to stop writing can be obtained according to the touch signal, and the writing track input by the user can be displayed in real time in the writing area of the touch screen according to the track data. Of course, the writing process is not limited to writing, and any input process for displaying an operation track implemented on the touch screen of the smart handwriting device may be regarded as the writing process. Further, the touch operation may be responsive to a click, a drag, or the like operation by the user according to a display element of the occurrence position of the touch operation. These different response patterns are identical in the underlying coordinate processing pattern.
Specifically, referring to fig. 1, the screen sharing method of the intelligent interactive tablet specifically includes:
step S101: and receiving a preset screen sharing triggering event.
The application scene of the intelligent interaction panel is usually a multi-person application scene, such as a conference (including a teleconference), teaching, discussion and the like, and an operator reveals information related to an interaction theme or records information generated in the interaction process through the intelligent interaction panel. The method specifically comprises the steps of showing the information related to the interaction theme, wherein the first method is to synchronize screen content in the personal computer in a screen throwing mode after connecting the personal computer, so that the information related to the interaction theme is stored and opened in the personal computer, showing the information related to the interaction theme to other people in an application scene in an intelligent interaction panel, and the second method is to locally open the information related to the interaction theme in the intelligent interaction panel, and directly completing the opening and showing of the information in the intelligent interaction panel.
Corresponding to the first data display mode, the implementation of the scheme needs to confirm that the screen data sent through the two-way data channel is received at first. For the screen data transmission realized by the HDMI line, because only the personal computer transmits the screen data to the intelligent interaction panel, the intelligent interaction panel cannot reversely transmit the data through the HDMI line to influence the picture display of the personal computer. Based on this, only when personal computer and intelligent interaction dull and stereotyped pass through two-way data channel and throw the screen time can carry out subsequent data operation, common two-way data channel is wifi and is corresponding to intelligent interaction dull and stereotyped throw the screen ware, wifi and throw the screen ware and have realized in prior art more, do not make repeated explanation here.
Corresponding to the second data display mode, the realization scheme needs to trigger the screen sharing control by the user, namely, the triggering operation of the screen sharing control is received. The presentation of data in the intelligent interactive tablet is typically done in a whiteboard application interface.
The application interface refers to an interactive interface for receiving and/or displaying information by an application, such as a video playing application, and the interactive interface is mainly used for displaying changed video pictures; the interactive interface of the application of the real-time communication type is mainly used for receiving and displaying the content input by the near-end user and displaying the content input by the far-end user; the application of the file editing class is mainly used for receiving and displaying the content input by the user; the interactive interface of the browser application is mainly used for receiving keywords input by users and displaying webpage contents obtained based on the keywords.
In this embodiment, the specific application interface refers to a user interface presented in the using process of the whiteboard application, that is, the whiteboard application interface. As described above, the whiteboard application refers to an application for a user to perform writing, displaying, and other operations, and may be used for generating writing according to a writing track of the user on the whiteboard application interface, and may also be used for inserting other multimedia elements such as graphics, pictures, tables, and the like on the whiteboard application interface. In the whiteboard application interface, the user can realize writing, drawing, erasing and other operations similar to the physical blackboard, and further has better digital functions of moving, saving, scaling, inserting pictures, adjusting colors, setting stroke weights and the like. Writing-based operations in whiteboard applications are well-established implementations of the prior art and are not described in detail in this scenario. In practical applications, the whiteboard application may also be named as a writing application, an electronic whiteboard application, a collaborative whiteboard application, or the like, regardless of the change in the names, as long as the application for realizing the above functions is equivalent to the whiteboard application of the present application.
In using a whiteboard application, the whiteboard application is typically displayed full screen, i.e. the whiteboard application fills the display area of the intelligent interactive tablet. In addition to using the initially presented material and writing added content and inserting displayed content during use, the content displayed in the whiteboard application interface also has corresponding tool controls for operating the above, which are normally displayed in the toolbar in the whiteboard application interface, in the example description of this embodiment, the toolbar is displayed at the bottom of the whiteboard application interface, and may be displayed on the left side and/or the right side, or even on the combination of the left side, the right side and the bottom in the actual layout. Some tool controls in the tool bar correspond to the digital implementation of the functions of the physical blackboard, such as writing, erasing, page turning (only part of the physical blackboard), and the like, and some tool controls are functional supplementary controls implemented on the basis of the whiteboard application, such as cancel input, restore input, handwriting selection, insertion, and the like. In this embodiment, what is adapted to trigger the screen sharing process is a screen sharing control, that is, when it is detected that the screen sharing control in the toolbar is triggered, it may be confirmed that a screen sharing trigger event is received. Of course, when the whiteboard application interface detects that the touch track is matched with the track feature corresponding to the preset screen sharing operation, the receiving of the screen sharing trigger event is confirmed.
Step S102: device information of surrounding intelligent interaction panels is detected.
The UDP multicast encryption information is sent and received at fixed time, and the UDP multicast encryption information carries the equipment information; or alternatively, the first and second heat exchangers may be,
and sending and receiving wifi beacon information regularly, wherein the wifi beacon information carries the equipment information.
In the actual screen sharing process, each intelligent interaction panel is possibly used as an initiating device of screen sharing and possibly used as a target device of screen sharing, so that in order to realize the screen sharing in the scheme, each intelligent interaction panel needs to inform device information of other intelligent interaction panels and also needs to know device information of other intelligent interaction panels, and therefore operations of sending and receiving the device information regularly exist. Specifically, the UDP multicast encryption information and the wifi beacon information are sent in a broadcast or multicast manner, where the broadcast is that a message is sent to all intelligent interaction boards in the network at the same time, and all the intelligent interaction boards can receive the message. Multicast is also called multiplex broadcast, and messages are sent from one intelligent interaction plate to a plurality of intelligent interaction plates appointed in a network, namely, to which intelligent interaction plates added into an appointed multicast group are opened, and each intelligent interaction plate can be added into the multicast group at any time through a program or can be withdrawn at any time. In the scheme, the method is suitable for intelligent interaction plates in the same local area network, and multicast objects can be directly confirmed by the IP address field. When each intelligent interaction panel sends UDP multicast encryption information and wifi beacon information at regular time, the intelligent interaction panel corresponds to the information sending of other intelligent interaction panels, and also receives the information at regular time.
Step S103: a list of devices is displayed for presenting the detected smart interactive tablet.
All the detected intelligent interaction tablet device information can be presented in the device list, or only the device identifier which can be read by the user can be displayed, for example: 1234 conference room, 403 classroom, etc., the user can know the location of the intelligent interactive tablet directly from the list of devices.
The device list displays not only the intelligent interaction tablet which can be directly detected by the intelligent interaction tablet which initiates sharing, but also the intelligent interaction tablet which can be indirectly detected, for example, the intelligent interaction tablet A can directly detect the intelligent interaction tablet B and the intelligent interaction tablet C, the intelligent interaction tablet B can directly detect the intelligent interaction tablet D, the intelligent interaction tablet C can directly detect the intelligent interaction tablet E, and the device displayed in the device list has the intelligent interaction tablet B, the intelligent interaction tablet C, the intelligent interaction tablet D and the intelligent interaction tablet E. Based on this, intelligent interactive tablets not in the same local area network can also realize the transmission of screen data in a serial link.
The detection of the intelligent interaction panel is completed by the intelligent interaction panel initiating the sharing or the intelligent interaction panel of the personal computer connected with the screen throwing, but the equipment list generated according to the detection result is displayed at the data source end of the screen sharing, namely, the equipment list is displayed on the intelligent interaction panel initiating the sharing or the personal computer initiating the screen throwing. That is, if the data source of the screen sharing is a personal computer, the intelligent interactive tablet transmits the device list to the personal computer for display after obtaining the device list.
Step S104: and receiving a target selection instruction, wherein the target selection instruction is used for confirming the intelligent interaction panel as a sharing target in the equipment list.
If the operation of the device list relation is detected after the device list is displayed, ending the screen sharing process, wherein the current display can meet the use requirement in the current application scene. The target selection instructions are touch operations detected in the equipment list, each touch operation serves as a target selection instruction to confirm a corresponding intelligent interaction panel, and the confirmed intelligent interaction panel serves as a sharing target to carry out subsequent screen sharing related processing. The method is suitable for displaying the equipment list on the intelligent interaction tablet or the personal computer, the target selection instruction is correspondingly received by the intelligent interaction tablet or the personal computer, and if the target selection instruction is received by the personal computer, the shared target is sent to the intelligent interaction tablet corresponding to the screen, and then the subsequent series link establishment and the screen data sending processes are carried out by the intelligent interaction tablet.
Step S105: and establishing a serial link according to the equipment information corresponding to the sharing targets, wherein one sharing target of two adjacent sharing targets in the serial link is used as a wireless hot spot to be connected with the other sharing target.
In the sending and receiving of the multicast encryption information based on UDP, the information comprises: a device unique identifier, an IP address, a hotspot ssid, a hotspot bssid, and a hotspot password. After receiving the encryption information, decrypting, judging whether the currently received equipment list contains the equipment information (judged by the equipment unique identifier), and if so, updating the information; and if the content is not present, adding a device list, wherein the list is the content obtained by the http interface.
In the sending and receiving of wifi beacon information, the information comprises: the device unique identifier, IP address, hotspot ssid, hotspot bsssid, and hotspot password, and add to the list when new device information is detected. That is, the device information includes a network parameter for logging in the target device in addition to the description information. For the manner in which the pass-through device is used to log into the target device, the network parameters include SSID (Service Set Identifier, service set identification), password, IP (Internet Protocol, protocol interconnecting between networks) address and port of the wireless access point. The screen transmitting client is connected to the wireless access point of the target equipment by using the SSID and the password, and is connected to the screen transmitting server through the IP address and the port. The UDP multicast encryption information and the wifi beacon information are only different in coding transmission modes, and the connection modes after the information is acquired are the same. After the intelligent interaction panel needing screen throwing is selected, performing udp package inquiry through a device list acquired by a udp at the moment, and if the device list is returned, connecting a Tcp for screen transmitting; if no return is made, the information in the wifi becaron can be provided, wifi connection is carried out, automatic networking is achieved, and then connection and screen transmission are carried out; and the like, the screen sharing among a plurality of intelligent interaction plates is completed. The whole serial link establishment process is realized by an intelligent interaction panel.
In order to solve the complex situation of using a scene network, the IP addresses, hot spot names and passwords of all devices can be collected to solve the problem that a user's computer is not in the same network, obtains a device list through an http interface, after selecting the devices, judges whether the devices can form a network or not through a udp packet inquiry mode (sending a udp packet to a designated IP, and considering that the devices can be normally connected if a reply can be received within 3 s), and if the devices cannot be connected, the router or wifi in the integrated machine can be disconnected through the hot spot names and the passwords in the information, so that the aim of automatic networking is achieved.
The intelligent interaction flat board that this scheme was mainly used, wherein from having the wifi module, the wifi module can set up to the AP mode, also can set up to the STA mode, in this scheme, for realizing the serial link, the wifi module needs to set up to two kinds of modes, in a serial link, former intelligent interaction flat board uses the AP mode as the hotspot, and the former intelligent interaction flat board of the mutual flat board of the later intelligent interaction with STA mode access.
Step S106: and transmitting screen data through the serial link.
The screen data is sent on the serial links, so that the sending task of the screen data can be shared to a plurality of intelligent interaction plates, each intelligent interaction plate only needs to send the screen data once, the data congestion of a certain data node is reduced, high-quality screen data transmission can be realized, and the reverse response of any intelligent interaction plate can be realized.
That is, on the basis of the above embodiment, the screen sharing method of the intelligent interactive tablet further includes:
and receiving and responding to the screen operation instruction detected by the sharing target. Common screen operation instructions are for example closing the current picture, adjusting the sound, etc.
On the basis of the above embodiment, the screen sharing method of the intelligent interaction panel further includes:
and when the sharing target is abnormal in the serial links, creating a serial link according to the equipment information corresponding to the rest sharing target.
Each intelligent interaction panel which enters the screen sharing can start monitoring service, and after the monitoring service is started, when the intelligent interaction device detects that a visual screen picture is input, connection is established with the appointed intelligent interaction panel, and the picture is transmitted to the appointed intelligent interaction device; and when the screen-transmitting state is detected to be exited, the intelligent interaction equipment is disconnected.
Referring specifically to fig. 2, the personal computer 10 initiates screen sharing to the intelligent interactive tablet 20, so that the intelligent interactive tablet 20 displays a corresponding device list on the intelligent interactive tablet 20 or sends and displays the corresponding device list on the personal computer 10 after detecting devices, and a user confirms that the screen sharing needs to be initiated to the intelligent interactive tablet 21, the intelligent interactive tablet 22 and the intelligent interactive tablet 30 through the device list, but the three intelligent interactive tablets cannot be all added to a serial link with the intelligent interactive tablet 20, at this time, the intelligent interactive tablet 20, the intelligent interactive tablet 21 and the intelligent interactive tablet 22 can form a serial link, and the intelligent interactive tablet 20, the intelligent interactive tablet 21 and the intelligent interactive tablet 30 can form a serial link, so that the distribution of screen data is realized at the intelligent interactive tablet 21. When the state of the equipment changes, the corresponding response is carried out through the processing mechanism.
Receiving a preset screen sharing triggering event; detecting equipment information of surrounding intelligent interaction plates; displaying a device list for presenting the detected intelligent interaction tablet; receiving a target selection instruction, wherein the target selection instruction is used for confirming an intelligent interaction panel as a sharing target in the equipment list; establishing a serial link according to the equipment information corresponding to the sharing targets, wherein one sharing target of two adjacent sharing targets in the serial link is used as a wireless hot spot to be connected with the other sharing target; and transmitting screen data through the serial link.
