摘要
轨道交通信号系统开发前应确定相应的安全完整性等级(SIL),以便采用与该SIL相匹配的安全管理和安全技术进行开发实现。以列车自动监控系统(ATS)的SIL等级确定为实例,对基于风险图方法确定系统SIL的过程进行介绍。
The safety integrity level （SIL） should be determined before the development of the rail transit signal system, so as to adopt the safety management and safety technique matching with the SIL. Taking SIL determination of the automatic train supervision system （ATS） as an example, the paper introduces a method of determining the SIL of ATS based on the risk map.
