    摘要:

    点式?基于通信的列车控制(BM-CBTC)多模列控系统的模式切换时延对城市轨道交通运营效率有着较大影响。分析点式?基于通信的列车控制(BM-CBTC)系统模式切换功能及过程,建立基于有色Petri网(CPN)的模式切换模型,研究不同点式(BM)控制系统设计运行间隔下的系统切换实时性。实验表明,切换时延随着BM设计运行间隔增大而增加,当BM设计运行间隔为2 min时能将列车运行晚点时间控制在5 min以内。建立的CPN模型亦可为其他配置的多模列控系统切换的实时性分析作为参考。

    Abstract:

    The mode switching time delay of the block mode-communication based train control(BM-CBTC) multi-mode train control system has a great impact on the operation efficiency of urban rail transit. First, this paper analyzed the function and process of mode switching in the BM-CBTC system. Next, it established a mode switching model based on coloured Petri net (CPN). Then, it studied the real-time performance of mode switching at different BM design operation intervals. The experiments show that the switching time delay increases with the increase of BM design operation interval, and the train operation delay can be within 5 minutes when the BM design operation interval reaches 2 minutes. The established CPN model also offers a reference for the real-time analysis of mode switching in other multi-mode train control systems.
