PLC在城市小型供水泵站中的应用

Application of PLC in Small Pump Station for Water Supply in City

1)对小型供水泵站实行远程控制和监测,实现自动控制和无人值守。2)采用罗克韦尔Compact Logix PLC实现对各种现场受控设备的自动、就地和远程控制,通过工业以太网交换机连通泵站管理所中心控制室。实现水泵的PID自动控制。采用Device-Net通讯采集变频器数据。

1） Remote control and monitor for small water supply pump station, automation control and no operator on site. 2） Use Rockwell Compact Logix PLC to perform control for auto、on site and remote controlto site equipment, use industry Ethernet switch to connect to pump management center. PID control for pump. Use Device-Net to collect data for VFD.
