应用于SCADA系统远程通讯的双信道冗余方案

摘要

为了保障SCADA(Supervisory Control And Data Acquisition,监视控制与数据采集)系统调度中心与现场间远程通讯的稳定性,为远程通讯提供可靠的通讯信道,本文利用冗余技术HSRP(Hot Standby Redundancy Protocol,热备冗余协议)和路由技术EIGRP(Enhanced Interior Gateway Routing Protocol,加强型内部网关路由协议),设计了两种双信道冗余方案:单端路由器冗余方案与双端路由器冗余方案.最后介绍了一个使用双端路由器冗余方案的应用案例.%In order to ensure the stability of the SCADA(Supervisory Control And Data Acquisition) s systems' remote communications between the control center and the field,and provide more reliabler communication links,we designed two dual-channels redundancy schemes with HSRP(Hot Standby Redundancy Protocol) and EIGRP(Enhanced Interior Gateway Routing Protocol) technology.There are single-end router redundancy scheme and double-ended router redundancy scheme. Then,we described a case which is ifnished by double-ended router redundancy scheme.
