摘要
通过理论推导得出了风机频率与瓦斯浓度的线性函数关系式,以此函数为基础,利用V4.0 STEP 7 Micro-WIN SP9等软件和变频器、风机、传感器等硬件设计了风机变频稀释超限瓦斯的自动控制系统。系统通过实时监测矿井巷道瓦斯浓度超限情况,可动态调控风机风量,实现快速高效地增风稀释巷道中浓度超限的瓦斯,对提高矿井生产安全具有重要作用。
It gets a linear function on the fan＇s frequency and the gas＇ s concentration by theoretical deduction,on the basis,it designs an automatic controlling system to dilute over-limit concentration gas by frequency converters,fans and sensors,etc.The system can timely modulate the fan ＇s air volume by constantly monitoring the gas＇ s concentration in the mine＇s roadway,it can increase the air volume to dilute the over-limit concentration gas quickly and efficiently and it plays an important role in upgrading the safe production of the mines.
