基于KVM技术的电力调度监控方案设计

Design of Electric Dispatching and Monitoring Scheme Based on KVM Technique

针对电力调度通信中心机房服务器和工作站等主机设备集中监控维护存在的问题及调度用工作站信号延伸的实际需求,设计了基于键盘、鼠标、显示器(keyboard,video,mouse,KVM)技术的3种电力调度监控整体方案。第一种为全模拟组网方案,根据主机房服务器和工作站的主机接口总数、监控室维护人员和调度集控人员所使用的显示器总数,选择对应的、独立配置的KVM矩阵;第二种为全数字组网方案,根据安全性要求,将机房的服务器和工作站等主机按照位于生产控制大区和管理大区的不同划分成2个子网,分别配置数字交换机(数字方案中以数字交换机替代了模拟方案中的KVM主机)和管理主机(HMX manager);第三种为模拟-数字混合组网方案,主机房监控维护部分采用模拟组网方案,调度集控员工作站信号延伸采用数字组网方案。建议根据调度通信中心自动化和调度专业的实际情况合理选用KVM技术方案,以提升和优化机房设备的综合监管能力,科学解决调度用工作站信号延伸问题。

In view of the existing problems in centralized monitoring and maintenance of such mainframe equipment as servers in computer room and workstations of power dispatch and communication center as well as the actual needs of dispatching workstations＇ signal extension, three power dispatching and monitoring solutions based on keyboard, video and mouse （KVM） are designed. The first is full analog networking scheme, which selects corresponding and independently configured KVM matrix according to the total of main computer room server and workstation mainframe interface, the total of displays used by monitoring, maintenance, dispatch and centralized control personnel. The second is full digital networking scheme, which, according to the safety requirements, divides such mainframes as computer room servers and workstations into two subnets respectively located in production control zone and management zone, and respectively configures digital exchanger （digital exchanger replacing KVM mainframe in the analog scheme） and HMX manager. The third is analog-digital networking scheme, analog scheme for monitoring and maintenance of main computer room, and digital scheme for signal extension of dispatch and centralized control workstation. It is suggested that KVM technical schemes be selected rationally in light of the automation and dispatch actualities in power dispatch and communication center, so as to improve and optimize the integrative supervisory ability for computer room equipment, and scientifically solve the signal extension problem of dispatching workstation.
