摘　　要：基于车车通信的移动闭塞是移动闭塞制式的一种新形式,其在前车和后车之间建立通信通道,后车在确定追踪目标点的时候考虑前车在制动过程中的前进距离,能实现比移动闭塞更紧密的列车追踪。通过对基于车车通信的移动闭塞制式下的列车追踪距离进行研究,并与既有固定闭塞、准移动闭塞、移动闭塞等闭塞制式进行对比分析,提出一种基于T值的列车追踪距离优化方法,该方法通过设立列车追踪稳定范围,做到了兼顾列车运行过程中的稳定性、舒适度与追踪距离。最后利用模拟软件,根据某一具体线路环境和列车条件进行仿真验证。仿真结果表明:与既有闭塞制式相比,启用基于T值的追踪距离优化方法能使基于车车通信的移动闭塞制式具有更加显著的优势。The moving block mode,enabled by train-to-train communication,is an innovative approach within train control.It established a communication channel between the preceding and tracking train,enabling the latter to factor in the progress distance of the preceding train during the braking process when determining the tracking target point,which can achieve closer train tracking than moving blocks.This study investigated the train headway based on the train-to-train communication moving block system and contrasted it with the existing block systems such as fixed blocking,moving-like blocks,and moving blocks.On this basis,a T-value-based optimization method for train headway was proposed.This method established a stable range for train headway,achieving a balance between stability,comfort,and train headway during train operation.Finally,simulation verification was conducted using simulation software based on a specific line environment and train conditions.The simulation results show that the T-value-based optimization method significantly enhances performance,offering distinct advantages over existing blocking systems.
