摘　　要：运行相同控制程序的配量相同的控制主机,通过实时数据交换模块形成互为热备份的冗余结构,利用可以自动切换的冗余配置的通讯网络以及冗余的现场控制单元,构成完整的双机热备控制,可极大提高控制系统的可靠性和安全性,满足如大型火电站、核电站、易燃易爆等特殊场合的控制要求。Hot redundant main controllers with same configurations and same control programs exchanging data via real time data exchange modules,working with auto-switching redundant networks and redundant field control units makes a complete hot stand-by redundant control system which greatly enhances the reliability and safety of the control system.This System can be applied in some critical industrial conditions such as large-scale coal-burning power generation,N-power station and other explosive industries,

关 键 词：控制系统 双机热备 热冗余 可靠性
