Coal mine air compressor unit control system

A coal mine air compressor unit control system comprises an air compressor control and operation table, a motor vibration sensor, a motor shaft temperature sensor, an air storage tank temperature sensor, an air storage tank temperature sensor, a pipeline flow sensor, a monitoring bolt, a switch, a main industrial personal computer and a standby industrial personal computer. The air compressor control and operation table comprises a PLC (Programmable Logic Controller), a 485 communication module, an analog input module, an isolation transformer, a 24V switching power supply, a 12V switching power supply, a switch and a touch screen; the PLC reads all operation parameters such as operation and fault words of the air compressor, and sends control words to control starting and stopping of the air compressor. The system has the advantages that the system has the functions of omni-directional monitoring of the running state of the air compressor, local and remote start-stop control, video monitoring, data storage a
