基于VPN的水箱远程实验系统的设计与实现

Design and Implementation of Remote Experiment System for Water Tanks Based on VPN

设计了一套基于VPN的水箱远程实验系统,通过资源共享来提高实验装置的利用率,描述了该系统的硬件平台、下位机运行程序和上位机监控界面。采用VPN技术,使实验者不必亲临现场,只需通过互联网即可接入系统,编写下载和调试程序,解决了目前基于工业控制系统的远程实验系统只能"监"而不能"控"的问题。

This paper designs a set of remote experiment system for water tanks, which is based on VPN. Through resource sharing, the utilization of experimental device is improved. The paper describes the hardware platform, program for lower computer and the monitoring interface for upper computer. By adopting VPN technology, experimenters can use the system far away from the field through Internet, also can compile download and debug program, download. So that the system solves the problem that can only monitor but can not control, which exists in current remote experiment system based on industrial control system.
