基于VPN的株洲某污水泵站远程监控系统的设计与实现

摘要

With an engineering case of a sewage pumping station in zhuzhou, analyzes the system configuration ofthe sewage pumping station and upper computer. Applies virtual private network （VPN） technology to combine PLC industrial control with remote communication for realizing the remote monitoring system. Meanwhile introduces technical characteristics and the definition of VPN, and expounds the key role of overall system structure and VPN on the control system. On-site operation proves the project is feasible.%为顺应系统远程监控的发展趋势，以株洲某污水泵站为背景工程，分析了该泵站和上位机的系统配置，并采用虚拟专用网（VPN）技术，把PLC工业控制和远程通讯结合起来，实现了该远程控制系统。同时介绍了VPN网络的定义及其技术特点，阐述了整个系统的结构及VPN网络在其中的关键作用。现场运行情况证明了该方案具有较强的可行性。
