Research on Mine Fan Speed Control System Based on the PLC control network

This paper designs a set of ventilation and dust removal in coal mine test device and PLC monitoring system. The ventilation and dust removal test device has a set of ventilation and dust removal functions, can automatically monitor air volume, air pressure, resistance and other performance parameters of ventilator and precipitator. The PLC monitoring system can remotely start and stop the variable frequency speed control on the ventilation machine and dust collector, and it can real-time monitor operation state, such as the running current and the parameters of ventilator and dust collector. The paper simulate and realize computer remote centralized monitoring of underground ventilation for mine ventilation system. The actual application shows that： the system is stable and reliable, simple operation, strong scalability.
