Sensing equipment has high after the interference of electromagnetic field, the traditional institution type signal sensor switch state monitoring methods produce wear problem, monitoring accuracy is reduced, therefore, put forward a kind of based on laser induced signal sensing switch state monitoring module, which include switch state laser induction module, communication module and back-end servers. By zero contact laser induction module, rely on the laser radiation measuring distance detection sensor switch actuator contact position, avoiding interference from high voltage side of the strong electromagnetic field. To obtain the signal sensing switch state feedback to the backend server, complete signal remote autonomous sensing switch state identification. Software design, gives the signal sensing switch state monitoring module of the main program flow chart and flow chart of serial port communication, and design the key code. The experiment result shows that the design of switch state monitoring module has high precision and efficiency of monitoring, monitoring of antinoise performance.
