| 摘 要： | 根据CTCS-1级列控系统总体设计方案，以安全控制为核心，结合系统理论事故模型和控制过程提出多层STAMP模型与相应的安全分析方法。利用UML语言对列控系统内部组件交互控制过程进行描述并将其转换为多层STAMP模型和故障分析模型，分析危险事件产生原因，实现对系统功能的安全分析。以CTCS-1级列车进站场景为例，建立多层STAMP模型并针对可能发生的危险事件进行系统功能安全分析。分析结果表明，多层STAMP模型和安全分析方法适用于CTCS-1级列控系统的功能安全分析。

| Abstract: | Multi-layer STAMP and its corresponding method of safety analysis combined with system theoretic accident model and processes(STAMP) were proposed based on the design scheme of CTCS-1 train control system. The interaction process between internal components of train control system was presented by using UML language, and it was transformed into multi-layer STAMP model and fault analyze model in order to analyze the causes of risk events, finally implement the security analysis of the system function. Taking the scenes of train pulling in station as an example, multi-layer STAMP model was established and used to analyze the system function security of potential risks. The result showed that the proposed model and method were suitable for function safety analysis of CTCS-1 train control system. |
