摘要
为满足煤矿对局部通风机自动调速的需求,设计了一种基于开关磁阻调速电动机的矿用智能局部通风系统。它采用开关磁阻调速电动机驱动,并以S7-200 PLC控制器和上位机组态的监控模式,根据井下传感器采集的瓦斯浓度信号实现自动按需通风,排放瓦斯功能。该系统经运行试验表明,取得了很好的节能效果。
In order to satisfy the automatic speed of mine local ventilation,designs one intelligent local ventilation system based on switched reluctance drive.It uses switched reluctance motor to drive,adopts control mode of S7-200 PLC controller and upper-computer configuration.This system can automatically ventilate and release gas according to gas concentration signal collected by underground coal mine sensor.By operation,it shows that the system gains good energy saving effect.
