Condition-maintenance-mode city rail vehicle auxiliary maintenance system

Abstract

A condition-maintenance-mode city rail vehicle auxiliary maintenance system is characterized in that a city rail vehicle condition monitoring module is used for receiving and synthesizing data related to operation and maintenance, performing data screening and calculation on the basis of the data related to maintenance to form key data related to maintenance, and receiving and storing diagnosing and potential safety hazard data provided by a vehicular diagnosing mainframe and a city rail vehicle potential safety hazard mining server; a safety evaluation module is used for performing city rail vehicle safety evaluation on the basis of the condition monitoring data, and performing fault analysis, potential safety hazard information screening and service life evaluation aiming at the key parts of a city rail vehicle at the same time; a maintenance redundancy design module performs maintenance scale estimation and maintenance cost estimation aiming at the evaluation results and provides reports, operation and maintenance staff makes maintenance decisions, and a resource optimization allocation module provides system urgency and time estimation at the moment; a maintenance plan making module provides interfaces allowing the operation and maintenance staff to perform fine adjustment and makes maintenance plans for vehicle maintenance according to selections.

Description

technical field [0001] The invention belongs to the field of automation, and in particular relates to a vehicle state-based maintenance auxiliary system for urban rail vehicle maintenance. Background technique [0002] The maintenance of urban rail vehicles is carried out at the vehicle base by the maintenance team. The maintenance team generally performs regular maintenance of the vehicles on a daily basis according to the planned repair schedule. The repair schedule is generally divided into daily inspection, monthly inspection, semi-annual inspection and annual inspection. Planned repair, the maintenance procedure is generally to take corresponding measures after the personnel regularly inspect and find faults, and this repair process has been used for many years, although the technical management office proposes revision opinions every year, but the changes are minimal. Many parts are mentioned in the repair schedule to be replaced when they are due, but at this time man...
