摘要
随着远程监控技术在生产生活中得到越来越多的应用,对远程监控系统展开研究是很有意义的事情。该文提出了一种远程监控系统,基于VPN技术实现跨越因特网与远程现场的数据连接,基于EtherNet/IP工业以太网协议实现远程客户端数据接口,最终实现远程监控。该系统利用OpenVPN协议建立数据通道,在OpenVPN服务器端通过RADIUS进行远程认证和用户管理;远程客户端通过OpenVPN客户端实现远程登录,利用EtherNet/IP协议实现与远程控制器的数据通信,在开发的监控界面下对远程设备进行监控。经过测试系统可以很好地实现远程监控,是一种可行的远程监控实现方案。
With more and more applications of the remote monitoring technology in production and life,it is very meaningful to do research on the remote monitoring system.This paper presents a remote monitoring system,realizes the data connection with the remote field over Internet based on the VPN technology,realizes the remote client data interface based on EtherNet/IP industrial Ethernet protocols,realizes remote monitoring finally.This system establishes the data channel using OpenVPN protocols,implements the remote attestation and user management in the OpenVPN server using RADIUS;In the remote client the system implements the remote login using the OpenVPN client,realizes the data communications with the remote controller using EtherNet/IP protocol,monitors the remote devices under the developed monitoring interface.The system can implement the remote monitoring quite well after test;it is a feasible scheme for remote monitoring.
