煤矿生产用水监控系统设计

摘要

针对传统的煤矿生产用水系统采用人工操作方式而无法实时了解水泵运行情况和水仓水位情况的问题,设计了一种煤矿生产用水监控系统.该系统包括多个PLC控制站,用于监控地面污水处理厂泵房、井下泵房和水仓；各PLC控制站采集传感器数据,并通过工业以太网将采集的数据上传至上位机；上位机根据采集的数据对工作泵、备用泵进行调度,并对电动阀门进行远程操作,从而实现自动控制功能.实际应用表明,该系统实现了多个泵房的无人值守及远程控制,提高了煤矿自动化水平.%In view of problem that traditional process water system of coal mine cannot real-timely know situations of running of pump and water level of sump with manual operation mode, a monitoringrnsystem of process water of coal mine was designed. The system includes many PLC control stations which are used to monitor pump house of surface wastewater treatment plant, underground pump houses and sumps. Each PLC control station collects data of sensors and uploads the data to upper computer through industrial Ethernet, the upper computer dispatches working pump and spare pump according to the data and makes remote operation for electric valve, so as to realize automatic control function. The actual application shows that the system realizes unmanned on duty and remote control for pump houses and improves automation level of coal mine.
