[0036] The wireless screen projection control method provided in the embodiment of the present application can be applied to terminal devices such as screen projection devices, mobile phones, tablet computers, wearable devices, vehicle-mounted devices, laptop computers, etc. The embodiment of the present application does not impose any restrictions on the specific type of terminal devices.

[0037] In recent years, wireless screen projection technology has been widely used in scenarios such as meetings, lectures, and classrooms to assist users in completing presentation tasks. However, during the screen projection process, the screen may be preempted by other devices, causing the presentation to be interrupted.

[0038] To solve this problem, the present application proposes a wireless screen projection control method, a wireless screen projection control device, a terminal device and a computer-readable storage medium, which can prevent the problem of screen projection being preempted by other user terminals when the screen projection device is in the startup lock mode, so that the screen projection can proceed normally.

[0039] To implement the technical solution proposed in this application, a screen projection device can be constructed first. Figure 1 The screen projection device is composed of a central control module and a screen projection display module, each module is connected to each other, and the screen projection device is connected to one or more user terminals ( Figure 1 Only 1) communication connection is shown.

[0040] Among them, the user terminal is a terminal device that may have a screen projection demand to implement the screen projection operation, the screen projection device is a screen projection device that can provide screen projection services, the central control module is a module on the screen projection device for intermediate control of the screen projection operation, and the screen projection display module is a module on the screen projection device for displaying the corresponding screen projection information according to the screen projection request. When the user terminal needs to perform screen projection, the user terminal can send a screen projection request including the IP of the user terminal to the screen projection device; after receiving the screen projection request sent by the user terminal, the central control module of the screen projection device can parse the screen projection request, obtain the IP of the user terminal, and determine whether the user terminal is a locked user terminal that has started the lock mode based on the user terminal IP. If the user terminal is not a locked user terminal that has started the lock mode, it is determined that the screen projection has failed, preventing the user terminal from preempting the screen projection during the process of the locked user terminal performing screen projection.

[0041] In order to illustrate the technical solution proposed in this application, a specific embodiment is provided below for illustration.

[0042] Figure 2 A schematic flowchart of the wireless screen projection control method provided in the present application is shown. As an example but not a limitation, the method can be applied to a screen projection device.

[0043] S101. If a screen projection request is received from a user terminal, the current working status is detected.

[0044] In a specific application, if a screen projection request is received from a user through a user terminal, the current working state of the screen projection device is obtained; the current working state includes the screen projection state and the screen non-projection state, and the screen projection request is a request to display the projection information through the screen projection device, carrying the user terminal IP and projection information. The projection information is the information that needs to be projected and displayed in the projection request, including but not limited to pictures or videos.

[0045] It is understandable that in order to achieve the goal of preventing the screen from being preempted by other user terminals during the screen projection process, the central control module must first be written into the screen projection device. When no function operation is performed, the central control module should be displayed on the interface of the screen projection device in a fixed form (for example, it can be set to a spherical shape); the specific operations are as follows:

[0046] First, you need to create a layout file, write the UI layout of the central control module, and instantiate the view control MasterBallView;

[0047] Then through WindowManager windowManager=

[0048] (WindowManager)getSystemService(WINDOW_SERVICE) gets the WindowManager service;

[0049] By setting the property value of WindowManager.LayoutParams.type to the floating property (WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);

[0050] Add the UI view control (MasterBallView) with completed layout to the window layer through the windowManager.addView(MasterBallView,layoutParams) method;

[0051] The MasterBallView control is processed with effects (for example, rounded corners, gradients, shadows, and colors) through GradientDrawable, and the central control module is displayed on the interface of the projection device in a 3D shape.

[0052] And use the attribute animation ValueAnimator to change the attributes of the MasterBallViewi control that realizes the 3D shape to achieve a persistent shape effect and present an animation effect;

[0053] Finally, set the onTouch listener for the MasterBallView control so that the user can drag and move the MasterBallView by touching it on the interface, and move the MasterBallView to any position in the middle or upper part of the screen to avoid affecting the screen operation experience.

[0054] S102. If the current working state is the screen projection state, check whether the screen projection lock mode is turned on.

[0055] In a specific application, if the current working state of the screen projection device is the screen projection state, then it is determined that the screen projection device is projecting and displaying the projection information corresponding to the screen projection request sent by other user terminals, and it is detected whether the screen projection lock mode of the screen projection device is turned on at this moment; among which, other user terminals are user terminals other than those that send the above-mentioned screen projection request; the screen projection lock mode is a pre-set mode in which during the screen projection process, only the content corresponding to the screen projection request sent by the locked user terminal is projected and displayed.

[0056] S103. If it is detected that the screen projection lock mode is turned on, parse the screen projection request to obtain the IP address of the user terminal.

[0057] In a specific application, if it is detected that the screen projection lock mode is turned on, the screen projection request is parsed to obtain the IP address of the user terminal carried in the screen projection request.

[0058] S104: Determine whether the IP of the user terminal is the same as the pre-stored IP of the locked user terminal.

[0059] In a specific application, determine whether the IP of the user terminal carried in the screen projection request is the same as the IP of the locked user terminal stored in advance. If the IP of the user terminal carried in the screen projection request is the same as the IP of the locked user terminal stored in advance, it proves that the user terminal currently sending the screen projection request is the same as the locked user terminal. At this time, a notification of "You have occupied the screen projection device" can be returned to the locked user terminal; if the locked user terminal sends an unlock request, the screen projection lock mode is turned off, and the corresponding screen projection information is displayed according to the above-mentioned screen projection request.

[0060] S105. If the IP of the user terminal is different from the IP of the locked user terminal, it is determined that the screen projection has failed, and a screen projection failure notification is generated and fed back to the user terminal.

[0061] In a specific application, if the IP of the user terminal carried in the screen projection request is different from the IP of the pre-stored locked user terminal, it proves that the user terminal currently sending the screen projection request and the locked user terminal are not the same user terminal, and the screen projection operation of the current screen projection request is determined to have failed, and a screen projection failure notification is generated and fed back to the user terminal that sent the above screen projection request.

[0062] In one embodiment, before step S101, the following steps are included:

[0063] S201: if a device connection request sent by the user terminal is received, updating the connection state of the user terminal to connected;

[0064] S202, parsing the device connection request to obtain the IP address and device name of the user terminal;

[0065] S203: Create a corresponding device list according to the IP address and device name of the user terminal.

[0066] In a specific application, if a device connection request is received from any user terminal, the connection status of the user terminal is updated to connected, the device connection request is parsed to obtain the IP and device name of the user terminal, and a corresponding device list is established based on the IP and device name of the user terminal; wherein, the device connection request is a request sent by the user terminal to establish a communication connection with the current projection device, so as to transmit the heartbeat and projection information of the user terminal in real time; the device list is a storage of the IP and device names of user terminals that have been successfully connected to the current projection device.

[0067] In one embodiment, after step S203, the following steps are included:

[0068] Obtain the heartbeat of all the user terminals in the device list;

[0069] If an abnormal heartbeat is detected for any of the user terminals, the device name of the user terminal with the abnormal heartbeat is deleted from the device list, and the connection status of the user terminal with the abnormal heartbeat is updated to unconnected;

[0070] Send an abnormal notification to the user terminal with the abnormal heartbeat;

[0071] If a screen projection request is received from the user terminal with the abnormal heartbeat, a screen projection failure notification is generated and fed back to the user terminal with the abnormal heartbeat.

[0072] In a specific application, the heartbeats sent by all user terminals in the device list that have established a communication connection with the current screen projection device are obtained in real time and detected. If the heartbeat of any user terminal is detected to be abnormal, it is determined that the user terminal cannot send a screen projection request, and the device name and IP of the user terminal with the abnormal heartbeat are deleted from the device list, and the connection status of the user terminal with the abnormal heartbeat is updated to disconnected. Heartbeat refers to the information periodically sent between the screen projection device and each user terminal. If the heartbeat information sent by the user terminal is not received within a preset time period, the heartbeat of the user terminal is determined to be abnormal. The preset time period may refer to the periodic time length for sending heartbeats. It can be understood that if the heartbeat information sent by the user terminal is not received within the periodic time length of a heartbeat, the heartbeat of the user terminal is determined to be abnormal.

[0073] In one embodiment, after step S203, the following steps are included:

[0074] Upon receiving a list display request sent by the user terminal, obtaining device names of all user terminals in the device list;

[0075] Display the device names of all user terminals in the device list and the connection status of the user terminals; wherein the connection status includes the connected state, the main speaker control connection state and the locked connection state.

[0076] In a specific application, if a list display request is received from a user terminal, the device names of all user terminals in the device list that have established a communication connection with the current projection device are obtained and displayed, and the connection status of each user terminal is displayed at the same time; wherein the connection status includes the connected status, the main speaker control connection status, and the locked connection status. The connected status indicates that the user terminal is connected to the projection device in communication, the main speaker control connection status indicates that the user terminal is connected to the projection device in communication and the main speaker control mode is turned on; the locked connection status indicates that the user terminal is connected to the projection device in communication and the projection lock mode is turned on.

[0077] like Figure 3 As shown, an application scenario diagram of a list display request is provided.

[0078] Figure 3 In the example, taking the user terminal as a mobile phone, upon receiving a list display request sent by the user terminal, the UI interface of the central control module in the 3D spherical form is expanded to present a square form, and at the same time, the device names of all user terminals in the device list that have established communication connections with the current projection device and the connection status of each user terminal are displayed.

[0079] In one embodiment, the method further comprises:

[0080] If a lock request is received from a user terminal, detecting whether the screen projection lock mode is turned on;

[0081] If the screen projection lock mode is not enabled, enabling the screen projection lock mode according to the lock request;

[0082] Taking the user terminal sending the locking request as the locking user terminal, updating the connection state of the locking user terminal to a locking connection state;

[0083] Parse the locking request, obtain the IP and device name of the locking user terminal, and save them.

[0084] In a specific application, if a lock request is received from any user terminal, it is detected whether the screen lock mode of the current projection device has been turned on. If the screen lock mode of the current projection device has been turned on, a "device has been locked" notification is returned to the user terminal; if the screen lock mode of the current projection device is not turned on, the screen lock mode of the current projection device is turned on according to the lock request, and the user terminal that sends the lock request is used as the locked user terminal. Correspondingly, the connection state of the locked user terminal is updated to a locked connection state, the lock request is parsed, and the IP and device name of the locked user terminal are obtained and saved, so that only the projection information corresponding to the projection request sent by the locked user terminal is displayed on the screen. It can be understood that the projection lock mode is a mode in which only the projection information corresponding to the projection request sent by the locked user terminal is displayed on the screen; wherein, the lock request is a request carrying the user terminal IP and device name to apply to turn on the projection lock mode of the current projection device.

[0085] In one embodiment, the method further comprises:

[0086] If a speaker control request sent by a user terminal is received, obtaining the connection status of the user terminal;

[0087] If the connection state is the connected state, obtaining the state of the speaker control mode;

[0088] If the state of the main speaker control mode is not started, the user terminal is used as the main speaker user terminal;

[0089] Turning on the speaker control mode according to the speaker control request, and updating the connection state of the speaker user terminal to the speaker control state;

[0090] Parse the speaker control request, obtain the IP address and device name of the speaker user terminal and save them;

[0091] If an instruction sent by the speaker user terminal is received, an operation corresponding to the request is performed; wherein the request includes a request to exit screen projection, a wireless snapshot request, a wireless speech request, and a mirror preview request.

[0092] In a specific application, if a speaker control request sent by a user terminal is received, the connection status of the user terminal is obtained. If the connection status of the user terminal is connected, it is determined that the user's heartbeat is normal, and the operation of sending a screen projection request can be executed to detect whether the speaker control mode of the current screen projection device is in the on state. If the status of the speaker control mode is started, a notification of "speaker control has been started, request failed" is generated to the user terminal; if the status of the speaker control mode is not started, the user terminal that sends the above-mentioned speaker control request is used as the speaker user terminal, and the speaker control mode is turned on according to the above-mentioned speaker control request, the connection status of the speaker user terminal is updated to the speaker control status, the speaker control request is parsed, and the IP and device name of the speaker user terminal are obtained and saved; the UI interface of the display control module is displayed on the screen of the speaker user terminal, so that when receiving the instruction sent by the user through the speaker user terminal, the operation corresponding to the request is executed; wherein, the request includes an exit screen projection request, a wireless snapshot request, a wireless speech request and a mirror preview request. The request to exit screen projection is a request to disconnect the communication connection with the current screen projection device and stop the screen projection operation; the wireless snapshot request is a request to quickly obtain the display content image (which can be understood as a request to take a screenshot of the current screen projection display content); the wireless speech request is a request to send audio data during the screen projection process; the mirror preview request is a request to play the screen projection information in real time during the screen projection process.

[0093] In this embodiment, the speaker control mode is a mode in which the UI interface of the control module is displayed on the screen of the speaker user terminal, and the user directly sends requests by touching, clicking, and other operations on the screen of the speaker user terminal and performs corresponding operations; it should be noted that in the speaker control mode, the screen projection device receives and only receives instructions sent by the speaker user terminal.

[0094] In this embodiment, when a request to exit screen projection is received from a user terminal, a pull-up screen projection instruction is generated and sent to the user terminal. The user terminal performs a simulated user screen projection action according to the above-mentioned pull-up screen projection instruction, and returns the screen projection instruction to the screen projection device. When the screen projection device receives the screen projection instruction returned by the user terminal, it responds to the screen projection, thereby pulling up the projection screen of the connected non-projected device.

[0095] As shown in FIG. 4 , an application scenario diagram for starting the main speaker control mode is provided.

[0096] Figure 4aIn the example, taking the user terminal as a mobile phone, after receiving the speaker control request sent by the user terminal, if it is detected that the connection status of the user terminal is connected and the status of the speaker control mode is not started, the user terminal that sends the above speaker control request will be used as the speaker user terminal, and the UI interface 001 of the central control module will be displayed on the screen of the user terminal, so that the user can directly operate the projection device through the user terminal.

[0097] Figure 4b In the figure, when the user touches or clicks the central control module UI interface, the central control module UI interface 002 in the 3D spherical form is expanded on the main speaker user terminal to present a square form, and the operation options that can be performed at the current moment are displayed (only operations such as exiting screen projection, wireless snapshot, wireless speech and mirror preview request are shown). As can be seen from the figure, the main speaker control terminal is meizuM6.

[0098] In one embodiment, after step S102, the method further includes:

[0099] If the screen projection lock mode is not turned on, the screen projection display is performed according to the screen projection request.

[0100] In a specific application, if the screen projection lock mode is not turned on, the above-mentioned screen projection request is parsed to obtain the IP, device name and screen projection information of the corresponding user terminal; the screen projection displays the corresponding screen projection information and saves the IP and device name of the user terminal.

[0101] In one embodiment, after step S101, the following steps are included:

[0102] If the working state is a non-screen projection state and the screen projection lock mode is turned on, parsing the screen projection request to obtain the IP address of the user terminal;

[0103] Determine whether the IP of the user terminal is the same as the pre-stored IP of the locked user terminal;

[0104] If the IP address of the user terminal is the same as the IP address of the locked user terminal, screen projection is performed according to the screen projection request;

[0105] If the IP of the user terminal is different from the IP of the locked user terminal, the screen projection lock mode is turned off and the screen projection display is performed according to the screen projection request.

[0106] In a specific application, if the current working state is not in the screen projection state and the screen projection lock mode is turned on, the screen projection request is parsed, the IP of the user terminal is obtained, and it is determined whether the IP of the user terminal is the same as the IP of the locked user terminal stored in advance; if the IP of the user terminal is the same as the IP of the locked user terminal, it is determined that the user terminal sending the above-mentioned screen projection request and the locked user terminal are the same user terminal, and the screen projection is displayed according to the screen projection request; if the IP of the user terminal and the IP of the locked user terminal are not the same, it is determined that the user terminal sending the above-mentioned screen projection request and the locked user terminal are different user terminals. In order to save screen projection resources, the screen projection lock mode is turned off, and the connection status of the locked user terminal is updated to the connected status, and a "screen projection mode has been released" notification is sent to the locked user terminal, and the screen projection is displayed according to the screen projection request.

[0107] This application starts the locking mode and determines that the screen projection has failed when it detects that the user terminal sending the screen projection request is different from the IP of the locked user terminal. It generates a screen projection failure notification and feeds it back to the user terminal to avoid the problem of the screen projection being preempted by other user terminals, so that the screen projection can proceed normally and the stability of the screen projection operation is guaranteed.

[0108] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
