Through the embodiment, the situation that the output signal of the circuit board at the secondary wire inlet position is unstable and the data deviation is large due to the damp influence in the scheme of acquisition and monitoring after the digital transformation of the relay can be effectively prevented, secondary correction can be performed through the data acquired by the camera, and meanwhile, dehumidification drying equipment is started and then monitored; and further, personnel inspection and power reduction accidents of shutdown are avoided.
