| Abstract: | TRE is one of the most important parts in metro signal train-ground wireless communication system.TRE power supply is an important system to ensure the continuous communication between train and trackside.In this article,from aspects of metro power supply system,signal power supply panel system,and TRE with its' cable design layout,the conventional analysis and fault tree analysis are used to make a qualitative and quantitative analysis of the reliability of TRE power supply system.The purpose is to verify the system's reliability in meeting the demands and to explore its weakness. |
