摘要
全自动运行列车车地一体化信息的传输,主要依赖于车地无线传输通道实现信息交互。目前大多数项目都只是应用2种无线传输通道,本文提出全自动运行列车同时应用3种无线传输通道应用案例,分别是无线电Tetra、LTE及WLAN通道。详细分析了每种无线传输通道优点、特点及不同的应用场景。同时根据应用场景对每种无线传输通道应用数据详细分类及对比,使得3种无线传输通道合理应用于同一项目列车,以实现对列车智能控制、智能运营及智能维护,更符合现代全自动运行列车应用场景。
The transmission of train-ground integrated information of fully automatic operation train mainly depends on the wireless transmission channel to realize information interaction.At present,most projects only apply two kinds of wireless transmission channels.This paper puts forward the application cases of three kinds of wireless transmission channels applied at the same time on fully automatic train,which are radio Tetra,LTE and WLAN channels.The advantages,characteristics and different application scenarios of each wireless transmission channel are analyzed in detail.At the same time,the application data of each wireless transmission channel are classified and compared in detail according to the application scenarios,so that the three wireless transmission channels can be reasonably applied to the same project train to realize intelligent control,intelligent operation and intelligent maintenance of the train,which is more in line with the application scenarios of modern fully automatic trains.
