摘要
为进一步提高煤矿井下泵房自动化监控水平,改善目前泵房监控效率低下、排水效率及节能性差等问题,采用自动化监测及智能排水控制技术,设计了一套基于PLC及智能传感器网络的煤矿井下排水智能监控系统系统。该系统以PLC作为控制核心,采用智能传感器网络对系统水压及水泵电机工况参数进行实时采集,形成集通信、监控、显示为一体的泵房无人值守系统,同时对排水控制策略进行优化,采用改进“避峰就谷”控制策略实现井下高效节能排水。经实验测试,该系统可有效实现井下泵房的远程自动化监测及节能排水控制,提高了井下排水效率及安全可靠性。
In order to further improve the automation monitoring and operation level of downhole pump houses in coal mines,improve the current problems of low monitoring efficiency,poor stability of water supply pressure and others in downhole pump houses,automation monitoring and variable frequency constant pressure control technology are adopted to design a set of coal mine downhole pump house constant pressure water supply control and unattended monitoring system based on PLC and intelligent sensor network.This system uses PLC as the control core,and real-time control of the water pump motor is conducted through variable frequency speed regulation and PID control strategy to maintain a constant water outlet pressure of water pump.An intelligent sensor network is adopted to conduct real-time collection of system water pressure and water pump motor working condition parameters,ultimately forming a pump house unattended system that integrates communication,monitoring,and display.Through experimental testing,This system can effectively achieve remote automation monitoring and energy-saving drainage control of underground pump houses,improving the water supply efficiency and safety reliability of downhole pump houses.
