核电站计算机室控制台KVM切换系统设计

Computer Room Console KVM Switchover System Design of Nuclear Power Plant

在整个核电站的仪控系统中,计算机室中包含多个服务器及工作站,核电仪控工程师需要利用极少的控制台,通过键盘视频鼠标系统(KVM)切换对计算机室中主要的服务器和工作站进行维护和调试。针对核电现场的具体要求进行设计,以满足利用少数控制台对多台服务器和工作站的主机进行显示和操作。显示功能的实现方法为控制台的主副屏对服务器和工作站的主副屏两路视频信号的显示;操作功能的实现方法为控制台的键盘鼠标可以操作服务器和工作站主机。整个系统设计功能实现可在3s内完成,系统验证后满足设计要求。

In the whole plant I&C system;the computer room contains multiple servers and work stations,the nuclear power plant I&C engineers need to use minimal consoles to maintain and debug the main servers and workstations through KVM switchover in the computer room.It aims at the specific requirements of the nuclear power plant site to meet the use of a few consoles to display and operate multiple servers and workstations on the hosts.The display functions include the consoles main and secondary screens’two video signal displays to the main and secondary screens of the server and workstation.The operation function for the console keyboard and mouse can operate the server and workstation hosts.The whole system design function can be realized in 3s.The system meets the design requirements after verification.
