摘要
为保证核电安全级DCS系统中控制站、安显站、网关站等之间双向、大容量数据的可靠通信,本文设计了一种基于光纤通信技术的多节点通信容错技术,并详细介绍了该光纤通信容错技术的设计方案及实现方法.该方案采用光开关切换技术灵活改变光传输路径,支持多节点通信网络容错通信,在多节点通信网络中某一个或多个节点发生故障时,不影响其他节点的正常通信,可灵活配置和管理多节点通信动态光路径切换,实现了核电安全级DCS系统中站与站之间的通信效率,提高了产品的可靠性和可用性,实现了多节点通信网络的容错设计.
In order to ensure the reliable communication of two-way and large-capacity data between the control station,security station,gateway station,etc.in the nuclear power safety-level DCS system,this paper designs a multi-node communication fault-tolerant technology based on optical fiber communication technology,and introduces the technology in detail.Design scheme and realization method of optical fiber communication fault-tolerant technology.The scheme adopts the optical switch switching technology to flexibly change the optical transmission path,supports the fault-tolerant communication of the multi-node communication network,and does not affect the normal communication of other nodes when one or more nodes in the multi-node communication network fail.It can flexibly configure and manage the dynamic optical path switching of multi-node communication,realize the communication efficiency between stations in the nuclear power safety-level DCS system,improve the reliability and availability of the product,and realize the fault-tolerant design of the multi-node communication network.
