摘　　要：为提高城市轨道交通CBTC自动控制系统的实时性,基于铁路数字移动通信系统(GSM-R)的列控通信系统,构建GSM-R首层模型、GSM-R下行链路模型和GSM-R信道模型,保证了列控数据传输的可靠性,降低了列控数据传输时延。最后,利用CPN Tools工具进行仿真。结果表明,所提基于GSM-R的列控通信系统模型,可完成数据帧在城市轨道交通列车与车站之间的传输与差错处理,实现了城市轨道交通CBTC的自动控制。相较于基于LTE-R的列控通信系统模型,所提模型最高运行速度提高了10 km/h,运行时间缩短了7 s,具有更好的实时性和追踪效率,能高效灵活地调整城市轨道交通列车的运行状态,且不容易受到信道质量的影响,为提高城市轨道交通CBTC自动控制系统的实时性提供了参考。In order to improve the real-time performance of the CBTC automatic control system of urban rail transit,the GSM-R first layer model,GSM-R downlink model and GSM-R channel model are built based on the train control communication system of the railway digital mobile communication system(GSM-R)to ensure the reliability of the train control data transmission and reduce the train control data transmission delay.Finally,the CPN Tools tool is used for simulation.The results show that the proposed train control communication system model based on GSM-R can complete the transmission and error processing of data frames between urban rail transit trains and stations,and realize the automatic control of urban rail transit CBTC.Compared with the train control communication system model based on LTE-R,the maximum running speed of the proposed model is increased by 10 km/h,the running time is shortened by 7 s,and it has better real-time performance and tracking efficiency.It can efficiently and flexibly adjust the running status of urban rail transit trains,and is not easily affected by the quality of the signal.It provides a reference for improving the real-time performance of urban rail transit CBTC automatic control system.
