It should be noted that the ground state tidal current section data includes telemetry data and remote signaling data, the telemetry data mainly includes some key point voltage, power and other parameters, and the remote signaling data refers to the on-off state of the switch. The preset switch state monitoring table records the switch names of the devices and the states of the switches to be monitored, and the preset switch state monitoring table corresponds to the preset switch state monitoring table one by one; and reading the real-time remote signaling opening and closing state to match with the state in the table, and finding the switch with the consistent opening and closing state, namely the switch with the consistent opening and closing state is successfully matched, wherein the successfully matched switch is called a monitoring switch.
