In the process of remote control of cable anti-theft electronic manhole cover, due to the poor communication performance of the current control system,the communication time is long,which provides an opportunity for criminals. In order to improve the safety of cables,a cable anti-theft electronic well cover remote control system based on NB-IoT technology is designed. On the basis of the current system hardware framework,NB-IoT module is added to optimize the central controller and power circuit. In the system software module,the electronic well cover remote control signal transmission module is added. According to the characteristics of the remote control signal,the PID controller is used to construct the remote control signal execution module of the electronic manhole cover. The optimization results of the system hardware and software are introduced into the current system orderly. So far,the design of the cable anti-theft electronic manhole cover remote control system based on NB-IoT technology has been completed. The test results show that the system is applicable and the wireless communication performance has been greatly improved. This system can reduce the communication time and ensure the timeliness of control instructions.
