摘　　要：轨旁无线设备(TRE)是地铁信号系统车地无线通信的重要组成部分,TRE供电系统是确保车地无线通信连续的重要系统。从地铁供电系统、信号电源屏系统、TRE及其电缆布置方式三方面着手,采用常规分析法和故障树分析法,定性、定量地分析常规结构下TRE供电系统的可靠性,以论证其可靠性是否满足要求,并探寻其短板。TRE is one of the most important parts in metrosignal train-ground wireless communication system.TREpower supply is an important system to ensure the continuouscommunication between train and trackside.In this article,from aspects of metro power supply system,signal power supplypanel system,and TRE with its′cable design layout,theconventional analysis and fault tree analysis are used to makea qualitative and quantitative analysis of the reliability of TREpower supply system.The purpose is to verify the system′s reliabilityin meeting the demands and to explore its weakness.
