摘　　要：研究开发冗余技术是提高电气控制系统可靠性的一条重要途径.研究了系统平均故障时间MTBF与系统可靠度R(t)的关系,并推论出冗余系统和热后备冗余系统的MTBF与故障率的关系,并由此提出了几种单元的比较合理的冗余结构设计.It is an important way to improve the reliability of electric control system by developing redundant technology. In this paper, the author makes a study of the relationship between mean-time-between-failures (MTBF) and the reliability (R) in the system, deduces the relationship between failure rate and MTBF of cold back-up redundant system and hot back-up redundant system and finally proposes designing several units of rational redundant structure.

关 键 词：冗余技术 可靠度 冗余结构
