双重冗余控制系统故障安全性的研究

Study on Fail-Safety of Dual Redundant Control System

为了获得或改善计算机控制系统的安全性 ,从确保系统故障后导向安全的角度出发 ,深入地探讨了双重动态冗余控制系统的故障 安全性 ,从理论上对冗余控制系统故障 安全性进行了分析和推导 ,给出了一般性结论 ,并结合铁路信号计算机控制系统 ,对双重冗余控制系统故障

In order to achieve and improve the safety of the computer control system,starting from ensuring to lead the system to safety side after failure, the fail-safety of the dynamic dual redundant control system is discussed in detail. The fail-safety of the system is theoretically analyzed and derived, and a general conclusion is drawn. This design principle and method are exemplified and probed in the computer controlled railway signal system.
