As shown in the figure, the communication system between the terminals may mainly include a first terminal 11, a second terminal 12, and a server 13. Specifically, the first terminal 11 in this example may be a smart phone, the second terminal 12 may be a large screen terminal, and the server may be the cloud server 13. The cloud server 13 is used as an application server and can communicate with the first terminal 11 and the second terminal 12, and if the user wants to use the first terminal 11 as a remote control device to realize remote control of the second terminal 12, a communication channel between the second terminal 12 and the first terminal 11 needs to be established.

In the above manner, the server 13 can be used as a communication transfer medium to establish communication connection between the first terminal 11 and the second terminal 12, and the first terminal 11 can be used as a remote controller to realize remote control of the second terminal 12. It can be seen that for the system shown in fig. 1, the communication method between terminals of the embodiment of the present invention may be performed by the server 13, or by the first terminal 11, or by the second terminal 12.

It should be noted that the system architecture shown in fig. 1 is only an example of an architecture of a system to which the scheme of the embodiment of the present invention is applied, and is not limited to an application scenario of the scheme of the embodiment of the present invention.

Specifically, the terminal control interface is a user interface for a user to interact with the terminal, where the terminal control interface may be equivalent to a virtual remote controller, and it may be understood that a control identifier for triggering a control command, such as a function button, may be displayed on the terminal control interface, and different function buttons may correspond to different control functions, and through the control identifier, a related control operation on the second terminal may be received. The control component corresponds to a terminal control interface of the second terminal, the control component can be used for adjusting related parameters of the second terminal, such as display brightness of a screen of the second terminal, and the control component can be configured based on actual requirements, such as different control components can be correspondingly configured based on different terminals.

The terminal scanning code is a graphic code which can be scanned and identified by the identification device, and comprises, but not limited to, a two-dimensional code and a bar code, wherein the terminal scanning code can be configured with information required to be informed or transmitted based on actual requirements.

Specifically, the specific implementation form of the control command may be configured based on actual requirements, for example, touch operation of the control identifier in the control interface of the touch terminal, or based on a voice command of the control identifier displayed on the control interface of the terminal, and the specific implementation form of the control command is not limited in the present invention.

The terminal identifier is configured based on actual requirements, for example, the terminal identifier may be a unique code such as a device ID or a device model of a corresponding device, and for convenience of description, the terminal identifier of the first terminal is hereinafter referred to as a first terminal identifier, and the terminal identifier of the second terminal is referred to as a second terminal identifier. Alternatively, the first terminal identification and the second terminal identification may be represented by an identifier uuid (Universally Unique Identifier, a universally unique identification code).

In the embodiment of the present invention, the first terminal is an electronic device having functions of scanning and identifying a terminal scanning code, network communication and information display, and the first terminal includes, but is not limited to, a mobile phone, a tablet computer, a portable computer, a VR device, an AR device, an IOT device, and other electronic devices.

The second terminal is an electronic device with a network communication function and an information display function, and the second terminal comprises, but is not limited to, a visual hardware large screen terminal and the like.

According to the scheme provided by the embodiment of the invention, the first terminal is used as the remote control equipment, so that the function of controlling the second terminal through the first terminal is realized. According to the scheme, whether the software and the hardware of the second terminal are compatible with the software and the hardware of the first terminal or not does not need to be considered, communication between the first terminal and the second terminal can be achieved through the scheme, development cost of remote control equipment is saved, and practical application requirements are better met. In addition, the user can realize interaction between the first terminal and the second terminal based on the terminal control interface, the operation is convenient, and the user experience is improved.

In addition, it should be noted that, the specific form of the terminal control interface corresponding to the control component may be configured according to actual requirements, which is not limited in the embodiment of the present invention. For example, as an alternative, the interface form of the terminal control interface may be the same as the interface form of the hardware remote control device of the second terminal entity, for example, if the second terminal device is a smart tv, the interface form of the terminal control interface may be the same as or similar to the control interface form of the entity remote control of the smart tv. As another alternative, since the terminal control interface is a virtual user interface, virtual control function buttons (hereinafter referred to as function buttons) in the terminal control interface may be displayed in a layered manner, for example, when there are more function buttons, control functions may be categorized in a control component of the terminal control interface, a function button of a previous hierarchy may be configured for each type of control function, a function button of a next hierarchy corresponding to each specific function button of each type may be configured, for example, a control function option, when the terminal control interface is displayed, each corresponding function button of each type may be displayed directly, and based on a touch operation of the user on the corresponding function button of the type of function, a function button of a next hierarchy corresponding to the type of function (that is, each corresponding function button of each control function, control function option) may be displayed again.

As an example, for example, based on the category of the control function corresponding to the control component of the second terminal, the control function of the second terminal is divided into two levels, where the first level includes two control identifiers, the two control identifiers are displayed in the form of different function buttons, the two function buttons are respectively a function button a and a function button B, the two function buttons are simultaneously displayed on the terminal control interface of the first terminal, the control function corresponding to the function button a is to adjust the brightness of the screen of the second terminal, the control function corresponding to the function button B is to switch the user interface displayed by the second terminal, in the second level, the function button of the next level of the function button a is to lighten and dim two control function options, and the function button of the next level of the function button B is to control two function options of the previous page and the next page. When the user triggers the function button B on the terminal control interface, the user wants to switch pages of the user interface displayed on the second terminal through the first terminal, after the user triggers the function button B, two control function options of the previous page and the next page can be correspondingly displayed, based on the two control function options, the user can select any one of the two control function options, if the control identifier corresponding to the next page is selected, the corresponding operation task is sent to the second terminal through the server based on the triggering operation of the control identifier corresponding to the next page, at this time, the control function corresponding to the operation task in the control command is switched to the next page in the page switching function, and the second terminal switches the user interface displayed on the current page of the second terminal to the interface displayed on the next page based on the operation task.

In an alternative of the present invention, the terminal scan code may be displayed at a designated location of the second terminal.

Specifically, the designated location may be configured based on actual requirements, for example, in order to hide information displayed by the second terminal when the information is not displayed on the screen of the second terminal, the terminal scan code may be displayed in an edge area of the screen of the second terminal, for example, an area of an upper left corner, an upper right corner, a lower left corner, a lower right corner, and the like of the screen of the second terminal.

Specifically, the application server provides a method that can be called by the client application program, and the application server can provide business logic for the application program through a plurality of protocols.

In an alternative scheme of the invention, the server can also be a cloud application server. The cloud server is based on the server cluster, so that the hardware redundancy is high, the failure rate is low, the computing capacity of the cloud server is higher than that of an independent server with the same configuration, and the requirement of high-performance computing can be met. The server may be a local server, and if the first terminal and the second terminal are in the same lan, communication may be implemented through the local server.

In an alternative aspect of the present invention, as shown in fig. 3, before receiving an operation of the user on the terminal control interface of the second terminal displayed on the first terminal, the method may further include steps S101 to S105, wherein:

Specifically, after the first terminal scans the terminal scanning code on the second terminal, the server may establish communication between the first terminal and the second terminal by using the server as a communication transfer medium based on the terminal identifier of the second terminal, and at the same time, the server may send the control component of the second terminal to the first terminal based on the terminal identifier of the second terminal, where the first terminal installs the control component and displays a terminal control interface corresponding to the installation component.

Specifically, the terminal identifier of each terminal and the corresponding control component may be stored in the server in advance, and when the server receives the communication connection request sent by the first terminal, the control component corresponding to the terminal identifier (the second terminal identifier) may be sent to the first terminal, so that the first terminal installs the control component in the first terminal.

In an alternative of the invention, the first terminal comprises a mobile terminal and the second terminal comprises a large screen terminal.

Specifically, the mobile terminal is a terminal with a function of scanning a terminal scanning code, and the large-screen terminal can display the corresponding terminal scanning code, for example, the mobile terminal can be a smart phone, and the large-screen terminal can be a smart television.

Based on the same principle as the method shown in fig. 2, the embodiment of the present invention further provides a method for communication connection between terminals, where the method is performed by a server, and the method may include:

step S210, a control command sent by the first terminal is received.

It can be understood that this step S210 is shown in fig. 2 as step S130, and as shown in fig. 2, the control command is generated for the first terminal by:

step S110, receiving the operation of a user on a terminal control interface through the terminal control interface of the second terminal displayed on the first terminal;

Step S120, a control command for the second terminal is generated according to the operation, wherein the control command comprises a terminal identifier of the second terminal and an operation task corresponding to the operation;

Step S220, according to the second terminal identification, the operation task is sent to the second terminal, so that the second terminal executes corresponding operation according to the received operation task.

It is understood that this step S220 is step S150 shown in fig. 2.

In an alternative aspect of the present invention, as shown in fig. 3, in step S210, before receiving the control command sent by the first terminal, the method may further include steps S101 to S105, where:

step S102, receiving a communication connection request sent by a first terminal;

wherein the communication connection request is generated by:

the terminal control interface is displayed in the following manner:

step S105, the first terminal installs the control component and displays the terminal control interface.

In an alternative aspect of the present invention, when the second terminal is started, or when all terminals connected to the second terminal are disconnected from the second terminal, the method may further include:

And transmitting the new terminal scanning code to the second terminal based on the second terminal identification, so that the second terminal displays the new terminal scanning code on the second terminal.

Specifically, the server may pre-configure the terminal identifier of each terminal and the corresponding terminal scanning code, and based on the second terminal identifier, the server may send the new terminal scanning code to the second terminal, which may specifically include the following two implementation manners:

the first method is that the second terminal actively obtains the data from the server, specifically: and when the second terminal is started or all terminals connected with the second terminal are disconnected with the second terminal, sending a scanning code acquisition request to the server, wherein the scanning code acquisition request comprises a second terminal identifier, and based on the second terminal identifier, the server sends a corresponding new terminal scanning code to the second terminal.

The second type is actively sent to the second terminal by the server, specifically: and when the second terminal is started or all terminals connected with the second terminal are disconnected with the second terminal, the server sends a new terminal scanning code corresponding to the second terminal based on the second terminal identifier.

It should be noted that, the terminal scan code of the second terminal may also be generated by the second terminal based on the corresponding terminal identifier.

In an alternative scheme of the present invention, the trigger connection request further includes a first terminal identifier, and after the second terminal establishes communication connection with the first terminal, the method may further include:

and sending the communication connection state identification to the first terminal based on the first terminal identification.

Specifically, the communication connection status identifier is used to identify a connection result, such as connection success or connection failure, of the second terminal and the first terminal, and based on the connection result, the first terminal can determine whether the communication connection is successfully established with the second terminal. The communication connection status identifier may be a set identifier, where different identifiers represent different communication connection statuses, for example, when the identifier is 0, connection success is indicated, and when the identifier is 1, connection failure is indicated.

In an alternative aspect of the present invention, the method may further include:

receiving a connection state query request sent by a second terminal, wherein the connection state query request comprises a second terminal identifier;

and based on the second terminal identifier, sending the communication connection state of the second terminal to the second terminal, wherein the communication connection state is the communication connection state between the second terminal and other terminals, the other terminals comprise the first terminal, and the communication connection state comprises any one of unconnected, connected and disconnected.

Specifically, the unconnected state indicates that the terminal has not established a communication connection with the second terminal, the connected state indicates that there is at least one terminal that has established a communication connection with the second terminal, and the disconnected state indicates that the terminal that has established a connection with the second terminal has been disconnected from the second terminal.

Optionally, in the foregoing solution, how to determine that all terminals connected to the second terminal are disconnected from the second terminal may specifically be determined by:

first, if the server does not receive the operation instruction sent by any terminal in the other terminals within the preset duration, it can be determined that all terminals connected with the second terminal are disconnected with the second terminal at this time.

Second, receiving a disconnection request sent by any one of the other terminals, wherein the disconnection request comprises a terminal identifier of any one of the terminals; and disconnecting the communication connection between the first terminal and any terminal established by using the server as a communication transfer medium based on the terminal identification of any terminal.

It may be understood that any terminal includes a first terminal, if any terminal is a first terminal, a trigger identifier for triggering a disconnection request may be preconfigured on a user interface of the first terminal, where the user interface may be a terminal control interface or another user interface, and the trigger identifier may be a function button, and when the button is triggered, a user triggers a request for disconnecting a communication connection with a second terminal, where the request is a disconnection request.

It will be understood that disconnecting the communication between the first terminal and the second terminal actually means that the server no longer receives any request sent by the first terminal and no longer forwards any information of the first terminal to the second terminal.

In the alternative scheme of the invention, if the second terminal and the first terminal are disconnected successfully, a disconnection result can be sent to the first terminal, whether the second terminal and the first terminal are disconnected successfully or not can be identified through the disconnection result, the disconnection result can be represented by a set identifier, for example, when the identifier is 0, the disconnection is successful, and when the identifier is 1, the disconnection is failed; the disconnection result can also be directly identified in the form of text, such as: "XX has been disconnected successfully, or XX has been disconnected failed," where "XX" may be the name of the device.

In this scheme, the second terminal can detect whether there is a terminal that successfully establishes communication connection with the second terminal in a polling manner, that is, periodically sends a connection state query request to the server.

In this scheme, when receiving the communication connection state query request sent by the second terminal, different communication connection states may be identified by different identifiers, that is, the server may send, to the second terminal, an identifier for identifying the communication connection state based on the second terminal identifier, where the identifier may be configured based on actual requirements, for example, when the identifier is 0, it indicates that the communication connection state is unconnected, when the identifier is 1, it indicates that the communication connection state is connected, and when the identifier is 2, it indicates that the communication connection state is disconnected.

Alternatively, when all terminals connected to the second terminal are disconnected from the second terminal, the terminal scan code transmitted to the second terminal may be a new terminal scan code.

It will be appreciated that if no terminal successfully establishes a communication connection with the second terminal, the terminal scan code displayed on the second terminal is unchanged.

Based on the above mode of judging whether all terminals connected with the second terminal are disconnected with the second terminal, when the server judges that all terminals connected with the second terminal are disconnected with the second terminal, the server actively sends the new terminal scanning code to the second terminal based on the second terminal identifier.

In an alternative aspect of the present invention, after the communication connection between the first terminal and the second terminal is established by using the server as a communication transfer medium, the method may further include:

Specifically, the number of the terminals that establish connection with the second terminal may be at least one, and if there are other terminals that want to establish communication connection with the second terminal at the same time, the identity of the corresponding terminal may be identified based on the terminal device information, that is, it may be known through the terminal device information, which user's terminal specifically establishes communication connection with the second terminal. The terminal device information is information for identifying the identity of the terminal, for example, the terminal device information may be a device model of the terminal, and if the user is a terminal scan code on a second terminal scanned based on a scan function of an application program on the first terminal, the terminal device information may also be a user ID (identification), an account name, etc. of the user on the application program.

Alternatively, on the second terminal, the terminal device information may be displayed in a preconfigured form, for example, the preconfigured form may be "XX connected", where "XX" may be a device name of the terminal device.

In an alternative scheme of the present invention, according to the second terminal identifier, the sending the operation task to the second terminal may include:

according to the second terminal identification, adding the operation task into an operation task queue corresponding to the second terminal identification;

first, when a task acquisition request sent by a second terminal is received, all operation tasks in an operation task queue corresponding to the second terminal identifier are sent to the second terminal, and the task acquisition request comprises the second terminal identifier.

Specifically, the second terminal may establish communication connection with the plurality of terminals through the method described above, or the first terminal may send a plurality of operation tasks to the server, for example, after the first terminal sends a first operation task to the server, the first terminal sends a second operation task to the server again, at this time, the server receives two operation tasks, and based on the two cases, the second terminal may simultaneously have a plurality of operation tasks acquired based on the task acquisition request, so that, in order for the second terminal to normally complete each operation task, an operation task queue may be established, after receiving the task acquisition request sent by the second terminal, the received operation task is added to the operation task queue corresponding to the second terminal, and then the server may send all operation tasks in the queue, that is, all tasks that the second terminal needs to do, to the second terminal based on the received task acquisition request.

In this scheme, the second terminal may acquire an operation task from the server in a polling manner, that is, the second terminal periodically sends a task acquisition request to the server.

As an example, after the second terminal establishes a communication connection with the first terminal (terminal a), the terminal a sequentially sends two operation tasks, namely, an operation task a and an operation task b, to the second terminal through the server, and when the time of receiving the operation task a by the server is earlier than the time of receiving the operation task b, in the operation task queue, the order of the operation task a precedes the operation task b, the second terminal acquires the operation task in a polling manner, that is, sends a task acquisition request to the server according to a preset time interval, and when the task acquisition request is sent, the operation task a and the operation task b are acquired simultaneously, and then the second terminal can sequentially execute the tasks corresponding to the operation task according to the order of the operation task a and the operation task b in the operation task queue.

And secondly, based on the second terminal identification, sending the operation task in the operation task queue to the second terminal.

Specifically, the server may further sequentially send the operation tasks in the queue to the second terminal according to the time sequence of the received operation tasks based on the task acquisition request, that is, after the second terminal completes one operation task, an identifier may be sent to the server, and the server sends the next operation task to the second terminal according to the sequence of each operation task in the operation task queue, or the server sends the next operation task to the second terminal according to a preset time interval and in sequence.

In an alternative solution of the present invention, if the operation task further includes a terminal identifier of the first terminal (first terminal identifier), after receiving the operation task sent by the first terminal through the terminal control interface, the method may further include:

and based on the first terminal identification, sending a task sending result to the first terminal.

Specifically, the task sending result is used to identify whether the operation task sent by the first terminal is successfully listed in the operation task queue of the server, where the task sending result may be configured based on actual requirements, for example, the task sending result may be identified by a set identifier, where when the identifier is 0, the sending is successful, and when the identifier is 1, the sending is failed.

In an alternative scheme of the present invention, after the second terminal completes the operation corresponding to the operation task, the method may further include:

and the server receives an operation result of completing the operation task, which is sent by the second terminal, and sends the operation result to the first terminal.

Specifically, after the second terminal completes an operation task, an operation result can be fed back to the server, the operation result indicates whether the operation task is successful or not, and based on the operation result, the server and the first terminal can know whether the operation of the second terminal is successful or not. The operation result may be configured based on actual requirements, for example, the operation result may be identified by a set identifier, where an identifier of 0 indicates that the operation is successful, and an identifier of 1 indicates that the operation is failed.

In an alternative aspect of the present invention, both the second terminal and the first terminal may communicate with the Server via Browser/Server mode B/S (Browser/Server) standard communication protocols.

Specifically, the B/S mode may concentrate the core part of the system function implementation on the server, that is, concentrate the implementation of the foregoing solution on the server, and implement, by the server, communication connection between the second terminal and the first terminal, and transmission of the operation task, etc., so that complex development of the second terminal and the first terminal may not be required, and thus development, maintenance, and use of the system may be simplified.

In an alternative aspect of the present invention, the B/S standard communication protocol includes at least one of hypertext transfer protocol HTTP (Hyper Text Transport Protocol), hypertext transfer security protocol HTTPS (Hyper Text Transfer Protocol over Secure Socket Layer), and web protocol WebSocket.

It will be appreciated that the communication method between the terminals described with the server as the execution body is substantially the same technical solution as the communication method between the terminals described with the first terminal as the execution body, but the solution is described from a different angle. The detailed description of the communication method between the terminals and the explanation of the scheme described with the server as the execution body may refer to the description of the communication method between the terminals when the first terminal is used as the execution body in the foregoing, and will not be repeated herein.

Based on the same principle as the method shown in fig. 2, the embodiment of the present invention further provides a method for communication connection between terminals, where the method is performed by a second terminal, and the method may include:

step S310, receiving an operation task sent by a server, wherein the operation task is information carried in a control command, and the control command is sent to the server by a first terminal.

It can be understood that this step S310 is shown in fig. 2 as step S140, and as shown in fig. 2, the control command is generated for the first terminal by:

step S120, according to the operation, generating a control command to the second terminal, wherein the control command comprises a terminal identifier of the second terminal and an operation task corresponding to the operation.

The terminal control interface is obtained by the first terminal through a control component provided with the terminal control interface, the control component is obtained by the first terminal sending a communication connection request to the server based on a second terminal identifier, and the second terminal identifier is obtained by the first terminal through scanning a terminal scanning code displayed on the second terminal;

It is understood that this step S320 is step S150 shown in fig. 2.

sending a scanning code acquisition request to a server, wherein the scanning code acquisition request comprises a second terminal identifier;

and acquiring and displaying a new terminal scanning code of the second terminal corresponding to the second terminal identifier.

Alternatively, the second terminal may send a scan code acquisition request to the server by means of polling.

sending a connection state query request to a server, wherein the connection state query request comprises a second terminal identifier;

the receiving server inquires a second terminal communication connection state sent by the request based on the connection state sent by the second terminal, wherein the communication connection state is a communication connection state between the second terminal and other terminals, the other terminals comprise the first terminal, and the communication connection state comprises any one of unconnected, connected and disconnected.

Optionally, the second terminal may send a connection status query request to the server by means of polling.

It will be appreciated that the communication method between the terminals described with the second terminal as the execution body is substantially the same as the communication method between the terminals described with the first terminal and the server as the execution body, and the description of the scheme is only from a different perspective. The detailed description of the communication method between the terminals and the explanation of the scheme described with the second terminal as the execution body may refer to the description of the communication method between the terminals when the first terminal and the server are used as the execution body in the foregoing, and will not be repeated here.

f) Close connection service: and the first terminal is used for disconnecting the communication connection with the second terminal and ending the communication.

The following describes the scheme of the present invention specifically based on the above several service commands, referring to a service call relationship diagram of each service command shown in fig. 4, and a flow diagram of a communication method between terminals shown in fig. 5, where in this embodiment, a first terminal is a mobile phone terminal, and a second terminal is a large screen terminal; the mobile phone terminal identifies the terminal scanning code on the large screen terminal through the scanning function in the WeChat applet, the corresponding terminal scanning code is the applet code, each terminal identification and the corresponding applet code as well as each terminal identification and the corresponding control component are preconfigured in the application server.

2. Starting a large screen terminal initialization task: and starting a large-screen terminal client process, calling a createQrcode service of an application server, acquiring a small program code corresponding to the large-screen terminal identifier (second terminal identifier) from the server based on the large-screen terminal identifier, and displaying the small program code on a screen of the large-screen terminal, wherein the small program code comprises a terminal identifier uuid of the large-screen terminal.

3. And starting a large-screen terminal to poll and inquire a communication connection state task: and the large screen terminal polls and calls a checkConnection service in the cloud application server, whether other terminals are successfully connected to the large screen terminal is detected through the service, if so, the information of the successfully connected terminal equipment is displayed, if so, the mobile phone terminal A can be displayed on the large screen terminal, if not, the small program code is continuously displayed, and the connection of the other terminals is waited.

If the successfully connected terminal is a mobile phone terminal a, after the cloud application server is used as a communication transfer medium to create communication connection between the mobile phone terminal a and the large screen terminal, the cloud application server returns an identifier for identifying whether the large screen terminal is in communication connection with the mobile phone terminal a to the large screen terminal, for example, when the identifier is 0, the communication connection state between the mobile phone terminal a and the large screen terminal is not connected, and when the identifier is 1, the communication connection state between the mobile phone terminal a and the large screen terminal is successfully established, that is, the communication connection state between the mobile phone terminal a and the large screen terminal is connected, and when the identifier is 2, the communication connection state between the mobile phone terminal a and the large screen terminal is disconnected.

4. Starting a mobile phone terminal to start a connection task: opening a sweeping function corresponding to a WeChat applet of a mobile phone terminal A, identifying a applet code on a large screen terminal, acquiring a terminal identifier uuid of the large screen terminal, triggering a communication connection request, wherein the communication connection request comprises the terminal identifier uuid of the large screen terminal, sending the triggering communication connection request to a cloud application server, calling a createConnection service of the cloud application server, using the cloud application server as a communication transfer medium, creating communication connection between the mobile phone terminal A and the large screen terminal, acquiring a control component of a terminal control interface of the large screen terminal based on the large screen terminal identifier uuid after connection is established, installing the control component in the mobile phone terminal A, and displaying a terminal control interface corresponding to the control component on the mobile phone terminal A;

if the mobile phone terminal a successfully establishes a communication connection with the large screen terminal, the server may send an identifier for identifying whether the mobile phone terminal a successfully establishes a communication connection with the large screen terminal to the mobile phone terminal a, for example, when the identifier is 0, it indicates that the mobile phone terminal a has successfully established a communication connection with the large screen terminal.

It should be noted that, the step 3 and the step 4 may be executed without any sequence, and the large-screen terminal may always execute the task of polling and querying the communication connection state to detect whether there is a terminal that is successfully established with the large-screen terminal.

5. Starting the mobile phone terminal to issue a control command task: after the mobile phone terminal A successfully establishes communication connection with the large screen terminal, a user can send an operation task to the large screen terminal based on the mobile phone terminal A, at the moment, the pushCommand service of the cloud application server is called, the operation task is sent to the corresponding large screen terminal through the server, and the instruction comprises a terminal identifier uuid of the large screen terminal and an operation type corresponding to the operation task.

If the operation instruction further includes a terminal identifier (first terminal identifier) of the mobile phone terminal a, after receiving the operation task sent by the mobile phone terminal a through the terminal control interface, the server sends a task sending result for identifying whether the operation task is successfully listed in the operation task queue of the server to the mobile phone terminal a based on the mobile phone terminal identifier, for example, the task sending result can be identified by a set identifier, when the identifier is 0, the sending is successful, and when the identifier is 1, the sending is failed.

6. And starting a large screen terminal to poll and acquire a control command task: the large-screen terminal polls and invokes the pullulan service of the cloud application server to obtain an operation task queue (corresponding to the operation instruction queue shown in fig. 4) issued by the mobile phone terminal, and at this time, if a plurality of terminals establish communication connection with the large-screen terminal at the same time and at least two mobile phone terminals send operation tasks to the server, the corresponding operation tasks can be executed according to the time sequence of receiving the operation tasks in the operation task queue.

After the operation is successful based on the operation task, the server sends an identifier for identifying whether the operation is successful or not to the mobile phone terminal based on the mobile phone terminal identification, for example, when the identifier is 0, the operation is successful, and when the identifier is 1, the operation is failed.

It should be noted that, the step 5 and the step 6 may be executed without any sequence, and the large screen terminal may always execute the polling query to determine whether a control command is received, that is, whether there is a task to be processed.

7. Starting a mobile phone terminal to disconnect the connection task: the user can issue a disconnection request based on the mobile phone terminal a, where the request may include a terminal identifier uuid of the large screen terminal and a terminal identifier of the mobile phone terminal, and at this time, based on the request, the mobile phone terminal invokes a close connection service in the cloud application server to disconnect the communication connection with the large screen terminal.

When the mobile phone terminal is disconnected from the large-screen terminal, the server may send an identifier for identifying whether to disconnect to the mobile phone terminal a, for example, when the identifier is 0, the connection is successful, when the identifier is 1, the connection is failed, and when the connection is failed, the connection disconnection request may be triggered again, so as to disconnect the large-screen terminal from the mobile phone terminal a.

8. Recall the createQrcode service of the application server: when the large-screen terminal polling inquiry detects that the connection of the mobile phone terminal A is disconnected, the createQrcode service in the cloud application server is called again, and similarly, the step 2 is returned to, a new small program code is acquired, and a communication connection request triggered based on the new terminal code scanning is waited to be received.

It should be noted that, in the embodiment of the present application, the execution sequence of steps 1 to 8 is not limited, for example, step 3 and step 4 may be executed simultaneously or may be executed separately, and those skilled in the art may set the execution sequence according to actual situations.

According to the scheme, whether the large-screen terminal is compatible with software and hardware of the mobile phone terminal or not does not need to be considered, and the mobile phone terminal can realize communication with the large-screen terminal through the scheme, so that development cost of remote control equipment is saved. In addition, the user can realize interaction between the mobile phone terminal and the large screen terminal based on the terminal control interface, the operation is convenient, and the user experience is improved.
