摘要
信息技术的高速发展,城市结构与居民需要都发生了巨大的改变,城市规模随之迅速扩大起来,伴随着轨道交通发展的同时,人们对其运营的效率标准也逐步提高。轨道交通技术中如何提高列车效率,缩小列车追踪间隔成为当前轨道交通技术研究的主题。本文基于移动闭塞模式下,无线通信延迟对列车追踪间隔产生的影响进行分析研究,建立通信延迟下的列车追踪数字模型,并分析其通信网络延迟的原因,总结影响具体因子,从而提出有效地解决方案,提高列车运行效率,保证列车安全运营。
With the rapid development of information technology,great changes have taken place in the urban structure and the needs of residents,and the urban scale has expanded rapidly.Along with the development of rail transit,the efficiency standards for its operation have been gradually improved.How to improve train efficiency and reduce train tracking interval in rail transit technology has become the research topic of current rail transit technology.This article is based on moving block mode,the impact of wireless communication delay on the train track interval analysis,establish communication delay of the train track digital model,and analyzes the reason for the delay,the communication network summary affect specific factors,so as to put forward effective solutions,ensure the safety of train operation.
