余度管理中输入信号的表决策略

为了提高安全可靠性及容错能力，在安全性和可靠性要求较高的系统中，通常会采用冗余设计，双余度即为一种常用的冗余策略。将对双余度计算机管理问题中的输入信号表决策略进行深入研究分析，包括三种表决算法：双通道平均值、双通道加权平均值、双通道和设备的综合，并对它们各自的特点进行了详尽的分析说明。

Voting Strategy for Input Signals of Redundancy Management

In the system with the higher safety and reliability requirement,the redundancy design that the dual redundant computer is usually used to improve the safety reliability and the fault-tolerant ability of the system. In this paper,we deeply analyze the input signal voting strategy,which is in the dual redun-dant computer management system,including three voting algorithms,dual channel average,dual channel weighted average,the synthesis of dual channel and equipment,and their respective characteristics are an-alyzed in detail.
