Study of Integrated Control System for Local Ventilator in Coal Mine
Abstract：Using fuzzy control and frequency changing technologies, the local fan motor speed is controlled according to the gas density, airflow demand and temperature at the heading. The system will be able to automatically change the fan＇ s airflow, to realize the air-power lock and gas-power lock, to monitor the air leakage rate of local ventilation system, the air flow and gas density ; and to alert and cut off the power at the heading during abnormity. The simulative curve of system is gained by Matlab simulation.
