As can be seen from fig. 2, after the controlled terminal requests the server terminal for the service data of the current page through the connection information, the controlled terminal checks whether the request is legal through the Token, if so, the service data of the current page is mapped to the Model layer, and then the performance field of the View Model layer is modified through the Model layer, the View Model layer provides the service data of the current page and the execution command, and the View layer is driven to modify the View and display the service data of the current page.
The process adopts an MVVM framework, and because the MVVM framework adopts bidirectional data binding, when a main control terminal switches scene pages, the data change in a View layer of the main control terminal is automatically reflected to the View Model layer, when a user performs interactive operation on the main control terminal, the data change in the View layer can be caused, the View Model layer drives the data change in the Model layer and transmits the data change to a gateway layer, and the gateway layer reflects the change to a controlled terminal, so that the picture change of the whole main control terminal is synchronous to the change of the controlled terminal.

judging whether the controlled end is broken accidentally, and when the controlled end is reconnected due to the accidental broken wire, recovering the broken controlled end to a scene page before the broken wire according to scene routing information when the controlled end is broken, wherein the method comprises the following steps:
s601, performing heartbeat detection on a plurality of controlled ends through a gateway layer, and judging whether accidental disconnection occurs at the controlled ends;
s602, if the controlled terminal is broken by accident, recording scene route information when the controlled terminal is broken;
s603, pushing scene routing information when the controlled terminal is disconnected to the reconnected controlled terminal when the gateway layer detects that the disconnected controlled terminal is reconnected according to the connection information;
s604, the reconnected controlled terminal restores to the scene page before disconnection according to the scene route information when the controlled terminal is disconnected.
In the above embodiment, when the data display is performed by the multi-screen linkage, it is inevitable that the controlled end is broken due to some unexpected reasons or faults, and after the repair, the controlled end needs to be reconnected to the multi-screen linkage data display system and continue displaying the page before the broken line, and then it is required to determine whether the controlled end is broken due to the unexpected reasons or the display ends to normally break the line.
The gateway layer carries out heartbeat detection according to the WebSocket channel information of the controlled terminal, wherein the heartbeat detection means that the controlled terminal sends a data packet to the gateway layer according to a preset period, and if the gateway layer does not receive a client message for a long time, the controlled terminal is indicated to be disconnected for some reason.
Whether the controlled end is disconnected or not can be judged through heartbeat detection, if the controlled end is detected to be disconnected, and if the controlled end is not the main control end to exit the display scene and send an exit instruction to the gateway layer, the gateway layer immediately distributes the exit instruction to a plurality of controlled ends, the plurality of controlled ends normally exit after receiving the exit instruction, and the controlled ends are considered to have unexpected disconnection.
The gateway layer can record the information of the controlled end of the disconnection and the current access scene page, namely the scene route information when the controlled end is disconnected, because the heartbeat information of the controlled end of the unexpected disconnection is not monitored.
When the disconnected controlled end uses the linkage code to log in again and returns to the multi-screen linkage display system, the gateway layer can detect that the previously disconnected controlled end is reconnected and push the scene route information of the last time the client end is located when the previous disconnected controlled end to the reconnected controlled end.
After receiving the scene routing information, the reconnected controlled terminal automatically jumps to the corresponding scene page, and automatically restores to the scene page before exiting. The whole process is carried out without a plurality of operators, and the scene page before the exit can be automatically restored only by carrying out linkage code re-login by the operators, so that manpower and material resources are saved.

s701, a main control terminal logs in a multi-screen linkage data display system through a preset account number and password, and connection between a gateway layer and the main control terminal is established;
s702, the gateway layer generates and stores a linkage code and channel information of a main control end;
s703, the gateway layer returns the linkage code to the main control terminal for display.
In the above embodiment, the preset account password login is set according to the actual use process, which is not further limited in the application, after the main control terminal logs in the multi-screen linkage data display system through the preset account password, the gateway layer will automatically generate the linkage code of the login and return the linkage code to the main control terminal for display, the screen of the main control terminal will display the linkage code, and the subsequent controlled terminal device can bind with the corresponding main control terminal according to the specific linkage code, but will not directly connect with the main control terminal. Meanwhile, channel information of the master control end, namely WebSocket channel information of the master control end, is automatically generated and serves as a basis for establishing connection between the master control end and the gateway layer, and interaction between the master control end and the gateway layer is conducted based on the WebSocket channel information of the master control end.
It should be noted that, the linkage code uses the atomic self-increment property of Redis, and when the login request of the master control terminal is received each time, id+1 of the self-increment Redis can ensure that the linkage code has no repetition, and then the self-increment id is converted into a 62-bit character string with the length of 6 bits, which is used as a globally unique Hash value.
In some embodiments of the present application, the connection information includes controlled-end channel information and connection parameter information; establishing connection between the gateway layer and the controlled end through the linkage code, comprising:
the controlled end logs in the multi-screen linkage data display system through the linkage code, and connection between the gateway layer and the controlled end is established;
