Safety Design of Network Control System in High-speed Train

介绍了高速列车网络控制系统的安全性需求、系统的安全设计层次,重点论述了RAMS工程,从安全需求、指标分配和评估、故障树分析、DFMEA分析等方面详细论述了网络控制系统安全性的保证措施,并提出了我国列车网络功能安全的一些思考与展望。

Safety requirements and safety design hierarchy of high-speed train network control system were introduced. RAMS engineer was briefly stated. Safety design of the high-speed train network control system were well described from safety requirement, safety qualification assignment and evaluation, fault tree analysis and DFMEA analysis, and some thought and forecast were proposed for China train network safety.
