基于KVM over IP技术的变电站微机监控系统移动工程师站

为了使变电站监控系统软件维护工作不再局限在主控制室内,针对变电站微机监控系统软件维护和故障排查的实际需要,提出利用键盘、显示器、鼠标的KVM over IP技术构建移动工程师站.KVM over IP技术从计算机键盘、显示器、鼠标的接口中获得模拟信号后,转换成数字信息包,并经过加密和压缩,在网络中利用TCP/IP连接进行传输,实现对计算机设备的远程控制.论述了移动工程师站的实现方法、设备接口、网络构建,给出了网络结构图,以及相应的安全机制(访问权限、数据加密、访问控制、信号仿真、网络隔离)等.

Mobile engineer station of substation supervisory system based on KVM over IP technique

According to the practical requirements of microcomputer -based substation supervisory system for software maintenance and fault examination outside the main control room,a mobile engineer station is built with KVM over IP technique using keyboard,video and mouse. KVM over IP technique obtains analog signals from keyboard,video and mouse and converts them into digital information package,which is then encrypted,compressed and transmitted via the TCP / IP link of network to remotely control the computer. The implementation of mobile engineer station is discussed,including equipment interface and network construction. The network structure and corresponding security mechanism are presented,including access authority,data encrypting,access control,signal simulation and network isolation.
