摘　　要：计算机联锁控制系统是保障列车在车站范围内安全、高效运行的基础设备 ,因而要求该系统具有更高的可靠性、安全性和可维护性 .为了提高系统的可靠性 ,联锁机通常采用冗余系统 .采用软件容错及硬件冗余相结合的方法 ,设计了一种基于Linux的双模动态冗余系统 。The microcomputer interlocking system is a kind of basic equipments,which guarantees the train’s safety and high efficiency in scope of the station. Therefore, the system should have far higher reliability, safety and maintenance. In order to promote the reliability of the system, the interlocking computer adopts redundancy system. Moreover, a dual modular dynamic redundancy system, which based on Linux OS, is presented by making use of software fault-tolerance and hardware redundancy. It realizes the design request.

关 键 词：客错系统 硬件冗余 软件容错 LINUX
