The GKT5 mine equipment start and stop sensor is a fixed monitoring instrument used to monitor the start and stop status of mechanical and electrical equipment (such as coal mining machines, conveyors, hoists, crushers, local fans, pump stations, fans, etc.) in coal mines. It is capable of converting the detected equipment start and stop signals into standard signals, transmitting them to the mine monitoring substation (or other carriers transmitting signals to the ground), and finally monitoring the start and stop status of all electrical equipment on the ground in a centralized, continuous and automatic manner. It can also be used as a basis for statistics on the operation quality, time and utilization rate of mechanical and electrical equipment.
