Automatic Control System of Coal Mine Air Compressor Based on PLC

In view of problem of artificial local control mode of traditional air compressor, the paper introduced a design of automatic control system of coal mine air compressor based on PLC. The system uses PLC as control core, which achieves functions of parameters acquisition, data processing, data remote transmission, fault alarm, automatic control and so on, and the system also realizes unmanned on duty for coal mine air compressor to lay a good foundation for digital mine.
