Currently,urban railway has entered a period of rapid development,and the number of urban vehicles is increasing day by day.In order to ensure the safe and efficient operation of urban vehicle,it is necessary to monitor the operating status of urban vehicle and issue fault warning.By adopting prognostics health management,the failure rate of urban vehicle on the main line can be effectively reduced,ensuring the smooth and efficient operation of urban vehicle.Research was carried out on the technical architecture of urban vehicle prognostics health management based on cloud and edge computing,including vehicle edge side architecture and cloud side architecture,to improve the reliability and availability of urban vehicle further.
