Abstract

Ensuring safe operation of level crossings is crucial in preventing fatalities and injuries at rail-road intersections. This study presents a Petri Net model of a level-crossing system that includes an obstacle detection system and dedicated protection signal to enhance safety. The model was analyzed using linear temporal logic and computation tree logic, with formal verification performed via TINA and TAPAAL tools. As a result of the model-checking experiments, the proposed Petri Net model successfully complies with the given safety criteria. Additionally, Fault Tree Analysis (FTA) was employed to systematically assess system-level risk, highlighting potential failure points and their impact. FTA provides a quantitative risk evaluation that complements the formal verification process, ensuring a thorough system reliability assessment.

轨侧保护系统的模型检验与验证

确保平交道口的安全运行是防止铁路公路交叉口伤亡事故发生的关键。本文提出了一种包含障碍物检测系统和专用保护信号以提高安全性的平交道口系统的Petri网模型。采用线性时间逻辑和计算树逻辑对模型进行分析，并通过TINA和TAPAAL工具进行形式化验证。模型检验实验表明，所提出的Petri网模型符合给定的安全准则。此外，采用故障树分析（FTA）系统地评估系统级风险，突出潜在的故障点及其影响。FTA提供了一个定量的风险评估，补充了正式的验证过程，确保了一个彻底的系统可靠性评估。
