CBTC系统列车混跑模式下非通信车跟踪技术研究

Research on Non-communication Train Tracking Technology in the Mixed-mode Operation of CBTC System

非通信车的识别及位置跟踪是CBTC系统实现列车混跑跟踪功能的关键。文章基于列车传统定位方式提出了非通信障碍区域的概念,并应用该概念进一步分析梳理了非通信车的位置及混跑跟踪过程中对相邻运行车辆的影响,为移动闭塞下列车的安全运行间隔控制及混合跟踪设计实现提供参考。文章从非通信障碍区域的产生、延伸原则、影响范围及消除4个方面分析了非通信车跟踪过程,最后对非通信障碍区域进行拓展应用,并说明了其关联功能。

Recognition and position determination of non-communication train is a key to realize train tracking function in mixedmode operation for CBTC system.Based on the traditional position determination method of train,the concept of"non-communication obstacle area"is defined and applied to further analyze the position of non-communication train and the impact of non-communication train on other running trains in the mixed-mode operation,which can provide references for the control of train safe separation and the realization of mixed-mode tracking design of trains under moving block.This paper firstly introduced the position determination method of the train,then analyzed the non-communication train tracking process from four aspects of the generation,extension principle,scope of impact and elimination of non-communication obstacle areas,and finally explained the functions associated with"non-communication obstacle area".
