According to the concept of " unmanned construction " in coal mine, a new intelligent system based on existing monitoring system and remote control technology is designed. The system collects the data of the underground endless rope railcar in real time by setting up various sensing devices and video monitoring equipment, transmits it to the monitoring terminal to analyze and judge the state of the railcar, sends signals in time to avoid risk factors, optimizes the efficiency of actual production activities, and enhances the safety of underground personnel. It has the potential of popularization and application.
