| 摘 要： | 在对比分析某市轨道交通列车5 min以上延误原因及特征的基础上,对不同列车运行控制制式的故障模式和可靠性进行了分析和建模计算。基于赋时Petri网建模方法,对CBTC(基于通信的列车控制)+BM(基于固定闭塞的点式列车自动防护模式)和CBTC+TBTC(基于数字轨道电路的列车控制)系统在降级模式切换时对列车运营延误的影响进行仿真分析。结果表明,当BM设计运行间隔较小时,列车延误可控制在5 min内;当TBTC设计运行间隔在100 s左右时,列车延误不超过2 min。对不同列车运行控制制式可靠性以及通信故障对运营延误影响的分析可为城市轨道交通线路信号设计、信号制式选取及实际运营提供参考。

| Abstract: | By comparatively analyzing causes and characteristics of a city metro train operation delays over 5 minutes,the fault mode and reliability of different train control system modes are analyzed and calculated with model.Based on Colored Petri Network(CPN)modeling method,the influence of CBTC+BM and CBTC+TBTC system downgrading mode on train operation delay is simulated for analysis.Results show that when the BM design headway is relatively short,operation delay can be controlled under 5 minutes;when the TBTC design headway is around 100 s,operation delays will not exceed 2 minutes.The analysis of the impact of different train control system modes reliability and communication fault on operation delay can be a reference for rail transit signaling system design,signaling format selection and practical operation. |
