基于通信的列控系统CBTC利用无线通信传递列车状态信息和控制命令，数据传输时延将引发不必要的列车牵引和制动，降低列控系统的性能。本文提出一种适用于CBTC的列控系统和数据通信系统的一体化设计方法，将CB T C的多列车控制系统等效为网络控制系统，建立一体化模型，分析传输时延对列控系统性能的影响。提出消除传输时延对列控系统影响的改进措施，并通过仿真验证该方法的有效性。

Communication-based train control(CBTC) systems use wireless communication to transfer the status and control commands of trains . T he delays in data transmission introduce unnecessary tractions and brakes of trains which degrades performance of the train control system . In this paper , we proposd a method to in-tegrate design of the train control system and that of the communication system for CBTC through modeling the train control system as a networked control system . An integrated model was set up . The effect of transmis-sion delay on performance of the CBTC system was analyzed . In addition , we proposed a method to remove the negative impact of transmission delays on performance of the train control system . The effects of the pro-posed methods were proved through simulation .
