Subway vehicle fault information management system based on FMECA

Abstract

The invention discloses a subway vehicle fault information management system based on FMECA. The system comprises a user management module, an information management module, a statistical analysis module, a system maintenance module and a help module. The information management module comprises a fault information storage module, a fault information input module, a fault information identification module, a fault information updating module, a calculation and decision module and a fault information output module. The statistical analysis module comprises a fault data statistical module, a fault rate analysis module, an FMECA analysis module and a maintenance decision analysis module. Standardized management of vehicle field data, mining analysis of the field data and determination of the reliability state of equipment parts are mainly realized so that a preliminary decision can be formed and vehicle maintenance rationality can be enhanced.

Description

Technical field [0001] The invention belongs to the technical field of subway vehicle information management, and particularly relates to a subway vehicle fault information management system based on FMECA. Background technique [0002] With the continuous development of my country's economy and the continuous expansion of the scale of cities, the urban public transportation system as the artery of urban population flow is facing increasing pressure. Urban rail transit has become an important part of urban public transportation due to its large capacity, punctual operation, safety and environmental protection, and other advantages. It not only facilitates citizens' travel, but also brings greater economic and social benefits to the city. Urban rail transit has become an important direction for the development of public transportation in major cities in my country. [0003] The subway transportation system is an important form of the urban rail transportation system. As an importa...

Problems solved by technology

[0005] However, although the depots of many subway operating companies have their own fault information management systems, the fault information management systems of many subway depots have fault information input, insufficient organization, too simple fault information management process, and insufficient fault data analysis and mining. This makes it difficult to make full use of valuable information reflecting the reliability status, fault characteristics and fault laws of subway vehicles
