通过对广州地铁3号线信号系统(车辆控制中心、车载控制器、列车自动控制等)安全性功能的介绍和应用分析,对系统组成、结构及功能设计上的一些安全理念进行较为详细的阐述,从而得出对该系统在安全性应用方面的一些分析见解。无论是移动闭塞还是移动闭塞信号系统,任何信号系统所必须遵循的安全原则是“故障导向安全”。 Through the introduction and application analysis of the safety functions of the signal system of the Guangzhou Metro Line 3 (vehicle control center, vehicle controller, train automatic control, etc.), some safety concepts on the system composition, structure and function design are described in more detail , To come to some analysis of the system in the application of security insights. The safety principle that any signaling system must follow, whether it is a moving or moving blocker system, is “fault-oriented safety.”
