Figures 2 and 3 show event request diagrams and data interaction diagrams according to embodiments of the present invention. The technical solution of the present invention is based on its flexible deployment capability and flexible deployment. Due to the adoption of the data service mode, it can be achieved: deploying one client on one machine corresponds to one screen server; deploying multiple clients on one machine Corresponding to different screen servers (for example, connecting the city bureau screen server and the county screen server at the same time); and directly deploying the client on the screen server, so that one machine can complete all functions (applied in disaster emergency, training and demonstration)

According to Figure 2 and Figure 3, the human-machine interface needs to access the real-time database or model database through the data service transfer, the human-machine interface program sends the data request to the data service through the Socket, and the data service directly reads the data and returns it to the machine through the Socket Interface, in order to improve programming efficiency and reliability, you can choose Socket (port) middleware such as ZMQ (N:M, that is, many-to-many encapsulation transport layer) or WebService for Socket programming. Among them, the "request/response" between the client and the server adopts a new model of "agent". In the server, Tskpaycrs (customer reporting system) is set as an agent, and there are multiple service programs (Tskpaywork) connected to it under Tskpaycrs. When Tskpaycrs receives a request, it will automatically assign the request to an idle Tskpaywork, and after Tskpaywork is processed, it will be returned to Tskpaycrs, and Tskpaycrs will send the response data to the client console. Advantages: If Tskpaycrs is abnormal, it will not affect the communication of other client consoles.
