摘要: 为了解决CTCS-3级列控系统GSM-R车地数据传输接口(Euroradio)安全功能模块没有提供时间相关风险防护措施的问题,建立基于DSPN的数据传输过程中故障恢复模型和通信模型。结合这2种模型并利用TimeNET4.0对数据丢失概率进行仿真,发现即使只考虑数据丢失才会造成列控系统危险输出的极端情况,仍不满足相关规范对于CTCS-3级列控系统数据传输SIL4级要求。
Abstract: In order to solve the problem that Euroradio’s safe functional module (SFM) of CTCS-3 train control system can not apply protective measures for time-related transmission risks, communication model and failure recovery model for transmission of CTCS-3 train control system are built which based on deterministic and stochastic Petri nets (DSPN). Combining the two models and using TimeNET 4.0 to simulate the result of data loss probability, a conclusion can be concluded that even considering that only data loss will cause dangerous of train control system, the result still can not meet the requirement of SIL4 based on the relevant specification for the CTCS-3.
