摘　　要：双机冗余备份是提高计算机系统可靠性的重要方式之一,而冗余切换装置作为系统实现的关键部分,承担着两套互为备份的计算机I/O接口信号的正确、可靠的选择与切换,是影响整个系统可靠性的重要环节。本文以一套双机冗余热备计算机系统为例,结合设备工程应用经验、取冗余切换装置若干典型技术问题作分析,阐述信号切换电路在实现过程中的设计注意点;所采取的措施已经实际使用验证,性能满足预期目标。Double redundant is one important way to improve the reliability of computer system, and redundant switching device as a key part of system implementation,bear the correct and reliable switching of the two sets interface signals of each other backup computers,it is an important part of reliability to the overall system.In this paper a dual redundant hot backup compute system a an example,combined with experience of engineering application,select some typical technical problems of redundant switching device for analysis,and describe the design point of signal switching circuit in the process of realization.All measures has been verified through actual use,its performance content the expectations.

关 键 词：冗余 备份 切换电路 典型问题.
