横沙岛集约化供水工程自控系统设计

The Design of Automatic Control System in Intensive Water Supply Project of Hengsha Island

针对横沙岛集约化供水工程信息整合及远程监控的需求,将虚拟专用网(VPN)技术、工业以太网技术、总线技术及GPRS技术有机结合,完成具有三级监控网络架构的自控系统设计,实现了给水泵站及管网监测点的远程监测及自动控制,最后总结工程中常用通讯技术特点,以期为类似工程设计提供参考。

In order to meet the control in intensive water supply layer network architecture is de requirements for information integration and remote monitoring and project of Hengsha island, the automatic control system with three- signed, by using virtual private network （VPN）,industrial ethernet, fieldbus and general packet radio service （GPRS）. The functions of remote monitoring, communication and automatic control are achieved. The characters of communication technology in project are summarized so as to provide reference for the design of water supply project.
