The following examples are described in detail.
Example one
Fig. 1 is a flowchart of a screen sharing method for an intelligent interactive tablet according to an embodiment of the present invention. The screen sharing method of the smart interaction tablet provided in the embodiment may be executed by an operating device of the smart interaction tablet, the operating device of the smart interaction tablet may be implemented in a software and/or hardware manner, and the operating device of the smart interaction tablet may be formed by two or more physical entities or may be formed by one physical entity. For example, the operating device of the smart interactive tablet may be a cell phone, an industrial control computer, or the like.
For convenience in understanding, in the embodiment, the smart interactive tablet is taken as an actual carrier, and detailed processes of triggering the sharing process, selecting the sharing target and transmitting the shared data when the screen sharing method of the smart interactive tablet is implemented are exemplarily described. The intelligent interactive panel can be an integrated device which controls the content displayed on the display panel and realizes man-machine interaction operation through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, a sound box, a television, a video conference terminal and the like.
Generally, a smart interactive tablet includes at least one display screen. For example, the smart interactive tablet is configured with a display screen with touch function, and the display screen may be a capacitive screen, a resistive screen, or an electromagnetic screen. In this embodiment, an intelligent interactive tablet is provided, and further, a user may implement a touch operation by touching a display screen with a finger or a stylus, and accordingly, the intelligent interactive tablet detects a touch position and responds according to the touch position to implement a touch function. Typically, the smart 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 smart interactive tablet may install at least one application having a writing function. The application program may be an application program carried by an operating system, and an application program downloaded from a third-party device or a server is also installed. Optionally, the application program has other editing functions besides the writing function, such as inserting tables, inserting pictures, inserting graphics, drawing tables, drawing graphics, and the like. And the drawn table or graph is a standard element drawn by the computer. Computer drawn standard elements may be understood as print standard elements drawn by an intelligent interactive tablet, which are distinguished from elements written by a user.
A touch screen configured by intelligent handwriting equipment such as an electronic whiteboard, an electronic blackboard, a digitizer, an intelligent conference tablet and the like is provided with a writing area for responding to the writing operation of a user to display input content, when writing is performed in the writing area, for example, a touch pen or a finger is used to touch the touch screen, the touch screen can sense the change of current, the change of voltage or the change of magnetic flux (corresponding to the specific setting type of the capacitive touch screen, the resistive touch screen or the electromagnetic touch screen), so as to obtain a touch signal containing the coordinates of the touch position and the trigger time of the touch signal, according to the coordinates of the touch position and the trigger time of the touch signal, track data of a writing track input in the process of writing to lifting and stopping writing by a stylus or a finger of a user can be obtained, and the writing track input by the user is displayed in a writing area of the touch screen in real time according to the track data. Of course, the writing process is not limited to writing, and any entry process implemented on the touch screen of the intelligent handwriting device for displaying the operation track can be regarded as the writing process. In addition, the touch operation may respond to operations such as clicking, dragging, and the like of the user according to the difference of the display element of the occurrence position of the touch operation. The way in which these different responses are processed at the bottom level is the same.
Specifically, referring to fig. 1, the method for sharing a screen of an intelligent interactive tablet specifically includes:
step S101: and receiving a preset screen sharing trigger event.
The application scene of the intelligent interactive tablet is generally a multi-person application scene, for example, in a conference (including a teleconference), teaching, discussion and other scenes, an operator presents data related to an interactive theme through the intelligent interactive tablet or records information generated in an interactive process. Specifically, the presentation of the data related to the interactive theme mainly includes two modes, the first mode is to synchronize the screen content in the personal computer in a screen projection mode after the personal computer is connected, the data related to the interactive theme is stored and opened in the personal computer, the data related to the interactive theme is presented to other people in an application scene in the intelligent interactive tablet, and the second mode is to open the data related to the interactive theme locally in the intelligent interactive tablet, and the data is directly opened and presented locally in the intelligent interactive tablet.
Corresponding to the first data presentation mode, the implementation of the present solution first requires confirming that screen data sent through the bidirectional data channel is received. For the screen data transmission realized by the HDMI line, because only the personal computer transmits the screen data to the intelligent interactive panel, the intelligent interactive panel cannot reversely transmit the data through the HDMI line to influence the picture display of the personal computer. Based on this, only when the personal computer and the intelligent interactive panel project screens through the bidirectional data channel, subsequent data operation can be performed, common bidirectional data channels such as wifi and a screen projecting device corresponding to the intelligent interactive panel are frequently realized in the prior art, and repeated description is not provided herein.
Corresponding to the second data presentation mode, the screen sharing control needs to be triggered by the user, namely, the triggering operation of the screen sharing control is received. The presentation of the data in the smart interactive tablet is typically done at the whiteboard application interface.
The application interface refers to an interactive interface used for receiving and/or displaying information, such as an application of a video playing class, and the interactive interface is mainly used for displaying a changed video picture; the real-time communication type application, wherein the interactive interface is mainly used for receiving and displaying the content input by a near-end user and displaying the content input by a far-end user; the interactive interface of the file editing application is mainly used for receiving and displaying the content input by the user; the interactive interface of the browser-type application is mainly used for receiving keywords input by a user and displaying webpage content obtained based on the keywords.
In this embodiment, the application interface specifically targeted refers to a user interface presented in the whiteboard application use process, that is, a whiteboard application interface. As described above, the whiteboard application refers to an application for a user to perform operations such as writing and displaying, and may be used to generate writing traces according to a writing track of the user on the whiteboard application interface, and may also be used to insert other multimedia elements such as graphics, pictures, forms, and the like on the whiteboard application interface. In the whiteboard application interface, a user can realize writing, drawing, erasing and other operations similar to those of an entity blackboard, and further has better digital functions of moving, storing, zooming, inserting pictures, adjusting colors, setting stroke weights and the like. Writing-based operations in whiteboard applications are a mature realization of the prior art and are not described in detail in this solution. In practical applications, the whiteboard application may also be named as a writing application, an electronic whiteboard application, a collaborative whiteboard application, and the like, and the application for realizing the above functions is equivalent to the whiteboard application of the present application regardless of changes in the name.
During use of the whiteboard application, the whiteboard application is typically displayed full screen, i.e. the whiteboard application fills up the display area of the smart interactive tablet. In the example description of the scheme, the toolbar is displayed at the bottom of the whiteboard application interface, and can be displayed on the left side and/or the right side during actual layout, even comprehensively displayed on the left side, the right side and the bottom. Some tool controls in the toolbar correspond to digital realization of the function of the entity blackboard, such as writing, erasing, page turning (only for part of the entity blackboard), and the like, and some tool controls are function supplement controls realized on the basis of 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 is confirmed that the screen sharing trigger event is received. Certainly, when the whiteboard application interface detects that the touch track is matched with the track characteristics corresponding to the preset screen sharing operation, it is determined that the screen sharing trigger event is received.
Step S102: and detecting the equipment information of the surrounding intelligent interactive flat plates.
Sending and receiving UDP multicast encryption information at regular time, wherein the UDP multicast encryption information carries the equipment information; or the like, or, alternatively,
sending and receiving wifi beacon information regularly, the wifi beacon information carries the equipment information.
In an actual screen sharing process, each intelligent interactive panel may serve as an initiating device for screen sharing or a target device for screen sharing, so that to implement screen sharing in the present scheme, each intelligent interactive panel needs to inform the device information of other intelligent interactive panels and also needs to know the device information of other intelligent interactive panels, so that operations of sending and receiving device information at regular time exist. Specifically, the UDP multicast encryption information and the wifi beacon information are sent in a broadcast or multicast manner, where the broadcast means sending a message to all the intelligent interactive tablets in the network at the same time, and the intelligent interactive tablets can receive the message. The multicast is also called as multicast, and the multicast is an intelligent interactive panel which sends messages to a plurality of intelligent interactive panels appointed in the network, namely to which intelligent interactive panels added to an appointed multicast group, wherein the multicast group is open, and each intelligent interactive panel can be added to the multicast group at any time through a program or quit at any time. In the scheme, the method is suitable for intelligent interactive panels in the same local area network, and the multicast can directly confirm the multicast object by the IP address field. When each intelligent interactive panel sends UDP multicast encrypted information and wifi beacon information at regular time, the intelligent interactive panels also receive the information at regular time corresponding to the information sending of other intelligent interactive panels.
Step S103: displaying a device list for presenting the detected smart interactive tablet.
All the device information of all the detected smart interactive tablets may be presented in the device list, or only the device identifiers that the user can read may be displayed, for example: 1234 conference room, 403 classroom, etc., where the user can directly know where the smart interactive tablet is located from the list of devices.
What is displayed in the device list is not only the intelligent interactive panel that can be directly detected by the intelligent interactive panel initiating sharing, but also the indirectly detected intelligent interactive panel, for example, the intelligent interactive panel a can directly detect the intelligent interactive panel B and the intelligent interactive panel C, the intelligent interactive panel B can directly detect the intelligent interactive panel D, the intelligent interactive panel C can directly detect the intelligent interactive panel E, and then the devices displayed in the device list have the intelligent interactive panel B, the intelligent interactive panel C, the intelligent interactive panel D and the intelligent interactive panel E, no doubt, the intelligent interactive panel a is the initiator of screen sharing, and is inevitably used as a node of a shared link, and is the initiator node. Based on the method, the intelligent interactive flat plates which are not in the same local area network can also realize the transmission of the screen data through the serial link.
The detection of the intelligent interactive panel is completed by the intelligent interactive panel initiating the sharing or the intelligent interactive panel connected with the screen-casting personal computer, 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 interactive panel initiating the sharing or the screen-casting personal computer. That is, if the data source shared by the screens is a personal computer, the smart interactive tablet sends 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 in the equipment list as a sharing target.
If the operation of the device list relationship is detected after the device list is displayed, the screen sharing process is ended, and the current display can meet the use requirement in the current application scene. The target selection instruction is touch operation detected in the device list, each touch operation is used as a target selection instruction to confirm a corresponding intelligent interaction panel, and the confirmed intelligent interaction panel is used as a sharing target to perform subsequent screen sharing related processing. The method is suitable for displaying an equipment list on an intelligent interactive panel or a personal computer, a target selection instruction is correspondingly received by the intelligent interactive panel or the personal computer, and if the target selection instruction is received by the personal computer, a shared target is sent to the intelligent interactive panel corresponding to screen projection, and then the processes of subsequent series link establishment and screen data sending are carried out by the intelligent interactive panel.
Step S105: and establishing a serial link according to the device information corresponding to the shared target, wherein one shared target of two adjacent shared targets in the serial link is used as a wireless hotspot and is connected with the other shared target.
In the sending and receiving of encryption information based on UDP multicast, the information comprises: a device unique identifier, an IP address, a hotspot ssid, a hotspot bssid, and a hotspot password. After receiving the encrypted information, decrypting the encrypted information, judging whether the equipment information exists in the currently received equipment list (judged by the equipment unique identifier), and if the equipment information exists, updating the information; and if not, adding a device list, wherein the list is the content obtained by the http interface.
In the sending and receiving based on wifi beacon information, information wherein includes: the device unique identifier, the IP address, the hotspot ssid, the hotspot bssid and the hotspot password are added into the list when new device information is detected. That is, the device information includes, in addition to the description information, network parameters for logging in the target device. For the method of logging in the target device by using the screen-transfer device, the network parameters include an SSID (Service set identifier) of the wireless access point, a password, an IP (Internet Protocol, Protocol for interconnection between networks) address, and a port. The screen transmission client is connected to the wireless access point of the target equipment by using the SSID and the password and then connected to the screen transmission server through the IP address and the port. The UDP multicast encryption information and the wifi beacon information are only in different coding transmission modes, and the connection modes after the information is acquired are the same. After the intelligent interactive flat plate needing screen projection is selected, the udp packet sending inquiry can be carried out through the device list acquired by the udp, and if the request returns, the connection can be carried out through Tcp to carry out screen transmission; if no return exists, providing information in the wifi beacon, carrying out wifi connection to achieve automatic networking, and then carrying out connection and screen transmission; and by analogy, screen sharing among the intelligent interaction flat plates is completed. The whole establishing process of the serial link is realized by the intelligent interactive panel.
In order to solve the situation that a network is complex in a using scene, IP addresses, hotspot names and passwords of all devices can be collected, so that a computer of a user who is not in the same network can acquire a device list through an http interface, after the device is selected, whether the devices can form a network or not can be judged through a udp packet sending inquiry mode (a udp packet is sent to a designated IP, and if the reply can be received within 3s, the devices can be normally connected), and if the devices cannot form a network, a router or wifi in an all-in-one machine can be disconnected through the hotspot names and the passwords in information, so that the purpose of automatic networking is achieved.
The mutual flat board of intelligence of this scheme main application, wherein have the wifi module certainly, the wifi module can set up to the AP mode, also can set up to the STA mode, and in this scheme, for realizing the series link, the wifi module need set two kinds of modes to, and in a series link, the mutual flat board of former intelligence uses the AP mode as the focus, and the mutual flat board of later intelligence inserts the mutual flat board of former intelligence with the STA mode.
Step S106: screen data is transmitted over the serial link.
The screen data is sent on the serial link, the sending task of the screen data can be shared by the intelligent interactive flat plates, each intelligent interactive flat plate only needs to send the screen data once, data congestion of a certain data node is reduced, high-quality screen data transmission can be achieved, and reverse response of any intelligent interactive flat plate can be achieved.
That is, on the basis of the above embodiment, by the characteristic of the data reverse transmission of the serial link, the screen sharing method of the smart 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, to turn off the current picture, adjust the sound, and the like.
On the basis of the above embodiment, the method for sharing a screen of an intelligent interactive tablet further includes:
and when the shared target is abnormal in the serial link, establishing a new serial link according to the equipment information corresponding to the residual shared target.
