摘要
Linux在电力系统自动化系统中的应用不断增加,不少控制系统和装置开始采用Linux及嵌入式Linux。为了方便开发人员协助现场工程人员对现场遇到的问题进行分析和定位,提出了一种基于P2P的远程维护工具的实现方法。其基本原理是利用OpenSSH软件在现场维护终端创建一个TCP服务器端,远程维护终端连接到现场维护终端时,现场维护终端与终端建立TCP连接,并利用网络地址转换技术通过TCP服务器进行两者之间的信息交互。利用该工具,开发人员可在远方利用OpenSSH客户端连接到远程的装置及计算机的OpenSSH服务器,通过SSH及SFTP对遇到的问题进行分析和定位。
As Linux or embedded Linux is increasingly applied in power automation systems,a remote maintenance tool based on P2P(Peer-to-Peer) is proposed to simplify the analysis and locating of site problems. Its basic principle is to set a maintenance server on site with OpenSSH(Open Secure SHell) software. The TCP connection is established between server and a remote maintenance terminal via Internet for information exchange using NAT(Network Address Translation) technique. Developer or maintenance engineer may work conveniently in local office on an OpenSSH client which is connecting with the remote OpenSSH server on site.
