摘要
结合燕化铁路的现状,总结近年来燕化铁路计算机联锁系统可靠性下降的原因,并将双机热备系统的可靠性和安全性与二乘二取二、三取二系统做MATLAB仿真比较,提出改良现有计算机联锁系统的建议。
The paper summarizes the reasons for the decrease of the reliability of computer interlocking system based on the present situation of Yanhua railway. And it makes a comparison among the hot-standby system, two out of two redundant system and three out of two redundant system in reliability and security with MATLAB simulation method, and puts forward the suggestion on improving existing computer interlocking system.
