In the prior art, when checking and accepting the remote signaling function of the factory station, on-site maintenance personnel are required to perform operations such as short-circuiting and disconnecting the terminal blocks on different devices used at the factory station site to simulate the remote signaling displacement signal . After the measurement and control device receives the injected remote signaling data, it will convert the remote signaling data in the form of analog signals into digital remote signaling messages, and pass these digital remote signaling messages through the station through a preset protocol (such as the 103 protocol) The Ethernet is transmitted to the master control device, and the master control device receives these remote signaling data messages, and performs protocol conversion on the remote signaling data messages (for example, converting the 103 protocol to the 104 protocol).

Further, the protocol-converted remote signaling data message is then transmitted to the master station through the power dispatching data network, and the front-end processor at the master station analyzes the received remote signaling data message and converts the parsed remote signaling data The message is stored in the database. Monitoring personnel can use the relevant programs in the workstation to check the remote signaling data to determine whether the remote signaling data is correct.
