摘要
考察了一种主动切换两单元贮备电子系统的可靠性,推导了其可靠性高于传统两单元贮备电子系统的条件。对于常见的两单元冷贮备电子系统,主动切换并不能提升贮备系统的可靠性,但能有效地提升任务完成时两单元同时正常工作的概率。
The reliability of a two-unit standby electronic system is studied. The condition of the proposed system with reliability higher than its classical counterpart is derived. For the common two-unit cold-standby electronic system, active switching can not effectively improve the reliability of the standby system, but can improve the probability that the two units can simultaneously work after the current task.
