Technique of Anti-interference of Computer-based Interlocking Software System in Metro

Computer-based Interlocking Software is a kind of system software with high reliability,usability and safety,but it needs to adopt some methods in hardware and software to meet customer requirements.This paper mainly introduces how to realize anti-interference with software in computer-based interlocking system in metro,and suggests the specification for each method.These methods were used in our projects and were proved to be effective methods,which can maximumly decrease influence to system operation,and ensure software to find the error resulted by interference.
