Urban vehicle health assessment system based on multi-level analysis
With the continuous acceleration of urban rail transit network construction in China,the increasing mileage of urban rail transit,the increasing density of passenger flow in the line network,and the shorter time interval between different trains,higher requirements are put forward for the operation and maintenance of vehicles under high load operation.How to evaluate the health of vehicles in a timely and effective manner is an important basis for ensuring the safe and stable operation of trains.This paper proposes a health assessment system for urban rail vehicles based on the multi-level analysis method,which comprehensive-ly considers the fault level and impact of each system and component of the vehicle.The health rating weight of each system and component of the vehicle are assigned based on the multi-level analysis method,and the vehicle health assessment model is estab-lished.In addition,this paper builds the vehicle health assessment system architecture and takes a domestic subway line as an ex-ample to design the vehicle health assessment system.
