摘要

安全控制系统是车辆安全功能链路的关键组成部分，对于保障整车安全具有至关重要的作用。为指导轨道交通车辆安全控制系统的设计，文章针对城市轨道交通车辆安全型控制系统的3种典型架构进行分析。通过考虑不同架构中是否存在共因失效约束，并结合硬件失效数据进行安全分析与计算，阐述了不同架构对系统失效率以及SIL等级的影响，计算结果表明，如要开发SIL3/SIL4安全控制系统，推荐采用1oo2或2oo3系统架构，且应重点关注共因失效。相关结果可为后续城市轨道交通车辆安全控制系统的设计提供参考与指导。

Abstract

Safety control system is a critical component within the safety function links on vehicles

playing an essential role in securing their overall safety. This paper presented an analysis of 3 typical architectures of safety control systems for urban rail transit vehicles

aiming to guide system design. Safety analysis and calculations were performed

taking into account potential common cause failure constraints across different architectures and incorporating data on hardware failures. Moreover

the impacts of different architectures on system failure rates and safety integrity levels (SIL) were examined. The calculation results indicate that

for the development of SIL3/SIL4 safety control systems

it is recommended to adopt a 1oo2 or 2oo3 system architecture

and special attention should be paid to common cause failures. The relevant findings serve as a reference and guidance for the subsequent design of safety control systems for urban rail transit vehicles.
