摘要
以某污水泵站为工程背景,设计了远程泵站监控系统,采用虚拟专用网(VPN)技术把PLC工业控制和远程通讯结合起来。简要介绍了VPN网络的定义及技术特点,阐述了整个系统的结构及VPN网络在其中的关键作用,并讨论了PLC和监控软件的实现。通过现场运行证明该方案具有较强的可行性。
A remote monitoring system is designed for sewage pumping station which use VPN to combine industrial control based on PLC with remote communication.Technical characteristics and function of VPN are stated in detail.The sturcture of the system,the relative functions,the realization of PLC and supervision software are also discussed in this paper.
