为了保障煤矿开采工作顺利进行,设计了一种煤矿综采工作面本质安全型组合开关控制方法。从本质安全型组合开关的特性角度设计开关控制器,该控制器使用传感器收集组合开关工作数据信号,处理并计算这些信号获得组合开关工作现状,根据该现状控制组合开关的动作,根据通讯协议实现本质安全型组合开关远程控制。仿真研究表明,该方法能够降低本质安全型组合开关的谐振频率,确保开关工作电流稳定,保障煤矿综采工作面各机械设备低功耗、稳定运行。

In order to ensure the smooth progress of coal mining,a Intrinsic safety combination switch control method for fully mechanized coal mining face was designed.The switch controller is designed from the perspective of the characteristics of the Intrinsic safety type combination switch.The controller uses sensors to collect the working data signals of the combination switch,process and calculate these signals to obtain the working status of the combination switch,control the action of the combination switch according to the status quo,and realize the remote control of the Intrinsic safety type combination switch according to the communication protocol.The simulation research shows that this method can reduce the resonant frequency of Intrinsic safety combination switch,ensure the stability of the switch working current,and ensure the low power consumption and stable operation of the mechanical equipment in the fully mechanized coal mining face.
