One socket of w5500 Ethernet chip is used to connect to the server host through TCP. After connecting to the server platform, the power environment monitoring terminal first sends local parameters, so that the server platform can bind the current socket to the database address corresponding to the platform, so as to store the later data in the database. The server platform will regularly send heartbeat packet instructions to all connected sockets to query whether the remote terminal is disconnected. The power environment monitoring terminal will send the collected object data to the server platform through socket after a series of data processing and judgment. When the user needs to control the remote terminal, open the remote terminal display interface through the web browser, click the function button, the server platform will send the control command to the remote terminal, and the remote terminal will return an execution result after executing the control command.
