摘要
该装置以瓦斯浓度的变化为参量 ,以单片机控制的变频调速系统为核心 ,调节风机的转速 ,实现矿井局扇通风的安全监控与节能 ,瓦斯自动排放高效、安全 ,消除了瓦斯事故 。
According to the parameter of changing gas consistency,the device,which center is the variable frequency system controlled by a single chip computer,realize the safe monitor and energy saving of mine local fan ventilation.Gas discharged efficiently and safely,and get rid of the gas accident.Its result of energy saving is obvious.
