摘　　要：煤矿瓦斯是影响煤矿安全生产的重要因素,而矿井通风机是煤矿生产中用来调节瓦斯浓度的重要设备。为了保证煤矿的安全生产,结合通风机的通风量和掘进巷道内的瓦斯浓度变化之间的关系,提出一种以PLC和变频器为控制器件,以风量和瓦斯浓度为主要测量参数的风机自动控制和监控系统。通过调节参数控制变频器频率,来改变风机电机转速,实现最优控制。该系统中上位机采用触摸屏控制,具有很好的人机交互,可实现对通风机良好的远程监控。Coalmine gas is one of the important influencing factors in safety production of the mine while coalmine ventilator is a very important equipment to adapt gas concentration to the coalmine production.In order toensure the safety production of the mine,in combined with the relationship between the ventilation quantity of the ventilator and the gas concentration variation in excavation tunnel,a automatic control and monitoring system with the main parameters of air flowand gas concentration is provided based on PLC and inverter.Optimum control can achieve through changing motor speed of the ventilation,which can realize by adjusting parameters to control thefrequency of inverter.The host computer of the systemis controlled by touch screen,which has a good human-computer interaction to ensure the implementation of a good remote monitoring to the ventilator.
