摘要
煤矿井下排水控制系统对促进煤矿发展有着重要的作用,本文以煤矿系统排水为研究对象,针对一些煤矿井下排水系统存在的问题,同时结合当前先进的自动技术,设计了一种适合我国煤矿井下排水的自动控制系统。本系统采用西门子S7-300PLC作为软件控制核心,构建基于PROFIBUS-DP现场总线的井下控制系统,利用工业以太网实现水泵机组的远程监控。系统设计有自动、远控、就地、手动四种控制方式。系统能实时测量水仓水位,根据水仓水位的变化,并结合"避峰填谷"原则,自动确定启动水泵的时间和台数,以达到节电目的。
The coal mine drainage control system development has an important role in promoting coal mine, based on the system of coal mine drainage as the research object,aiming at some problems existing in the coal mine drainage system,combined with the current advanced automatic technology at the same time, we design a suitable for the automatic control system of coal mine drainage in our country.This system adopts the Siemens S7-300 PLC as control core software,build a downhole control system based on profibus-dp field bus,industrial Ethernet is applied to realize remote monitoring of pump unit.System design are automatic,remote control,in situ,four kinds of control modes manually.System can real-time measuring water warehouse water level,according to the change of water warehouse water level,and combined with the principle of "peak valley",automatically determine the start time and the Numbers of the pump,to achieve energy saving purpose.
