Abstract

列车自主运行系统（TAOS）已成为城市轨道交通的重要发展方向。无线传输直接影响列车控制系统的性能。该文提出一种定量评估TAOS中无线传输可靠性的方法。列车到列车（T2T）和列车对地（T2G）传输都被考虑在内。基于分层定时彩色培养皿网建立模型，分析了不同类型通信过程对传输时延和丢包的影响。无线传输的可靠性是根据由于丢包而在预定时间内的紧急制动次数进行定量评估的。通过仿真比较了TAOS与基于通信的列车控制（CBTC）系统无线传输的可靠性。同时，还提出了一种提高TAOS无线传输可靠性的措施并进行了验证。仿真结果表明，TAOS中无线传输的可靠性为99.83%。通过应用改进措施，可以提高到99.92%，比CBTC系统提高0.04%。
