摘　　要：车车通信列车运行控制系统中移动授权的生成对城市轨道交通运营效率有着较大的影响。通过分析车车通信列车运行控制系统中移动授权的生成过程及性能,建立基于有色Petri网(colored Petri net,CPN)的车车通信移动授权信息交互的模型,进行性能分析。研究移动授权生成过程中端对端通信传输时延的延时概率,根据不同信道质量下统计传输时延的平均值,计算移动授权完成的成功率。分析结果表明,基于车车通信的列车运行控制系统移动授权的生成过程,符合地铁长期演进(long term evolution for metro,LTE-M)系统端到端延时时间不大于150 ms的概率不小于98%,时延随着信道质量的下降而增加。The generation of movement authority in train-based train control system has a great effect on the operation efficiency of urban rail.By analyzing the generation process and performance of movement authority in train-based train control system,a colored Petri net(CPN)based train authorization information interaction model is established to analyze the performance.The delay probability of end-to-end communication transmission delay in the generation process of movement authority is studied.According to the average value of transmission delay under different channel quality,the success rate of movement authority is calculated.The analysis results show that the generation process of movement authority of train operation control system based on train to train communication conforms to long term evolution for metro,and the probability that the end-to-end delay time is not more than 150ms is not less than 98%.The delay increases with the decrease of channel quality.
