| description | 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. |
