Design of Monitoring System for Electromechanical Equipments of Coal Mine

In order to know running state of main electromechanical equipments of coal mine, the paper proposed a design scheme of monitoring system for electromechanical equipments of coal mine. The system uses temperature sensor, pressure sensor and electric acquisition box to collect running state data of main electromechanical equipments of coal mine such as fan and hoist, and sends the data to monitoring substations which communicate with upper computer of surface monitoring center through RS485 bus, so as to realize remote monitoring function for underground electromechanical equipments. Long-time performance test result showed that the system has perfect running state.
