介绍了煤矿主排水泵自动控制的设计理念和PLC在煤矿主排水控制系统中的应用。该控制系统实现了对水泵的自动控制,PLC根据水位的变化和通电信息的因素建立模型实现了水泵自动开停、故障自动诊断和排除等功能,提高了煤矿矿井安全生产的安全性与可靠性。
The design concept of automatic control of main drainage pump in coal mine and the application of PLC in main drainage control system of coal mine are introduced. The control system realizes the automatic control of the pump. The PLC establishes the model according to the change of water level and the information of power-on, realizes the functions of automatic pump stop and start, automatic fault diagnosis and elimination, and improves the safety and reliability of coal mine safety production .
