A method and system for determining the health status of a railway track

Abstract

The invention discloses a method and a system for determining the health state of a railway track. The method comprises the steps that the railway track is divided according to preset length, and track meshes are obtained; track equipment in each track mesh is acquired; health condition influence indexes of the track equipment in the track meshes are acquired, wherein the influence indexes includeuse performance evaluation indexes, structural integrity evaluation indexes, safety evaluation indexes and appearance evaluation indexes; fuzzy processing is performed on the influence indexes; a railway track health state comprehensive evaluation fuzzy rule base is established; comprehensive evaluation indexes are acquired; a threshold range which the comprehensive evaluation indexes belong to is judged; and the health state of the railway track is determined according to the threshold range which the comprehensive evaluation indexes belong to. Through the method and the system, the railwaytrack state can be comprehensively evaluated, the reliability of health state evaluation of the railway track is improved, and therefore maintenance is better organized and arranged.

Description

technical field [0001] The invention relates to the technical field of railway transportation, in particular to a method and system for determining the health status of railway tracks. Background technique [0002] Railway track is a typical linear asset, which is a collection of various equipment, including steel rails, sleepers, ballast beds, coupling parts and anti-climbing equipment. Due to the linear and continuous distribution characteristics of railway track in space, its state deterioration and disease occurrence are affected by many factors. The railway status evaluation index can not only describe the running status of the railway track equipment, but also guide the goal and direction of the maintenance decision-making of the railway production department. An unreasonable status evaluation index system will lead to inappropriate maintenance activities. Therefore, how to use a reasonable condition assessment index system to carry out reliable maintenance of railway...

AI Technical Summary

Problems solved by technology

[0005] At present, to evaluate the health status of railways, one is to separately evaluate the state of a certain type of equipment in the track, ignoring the linkage of the state degradation of various equipment in the railway track, and the assessment object cannot reflect that the railway track is a collection of various equipment ; Second, for a typical linear asset such as a railway track, the status of a certain type of equipment in the track is generally evaluated according to the entire line, interval, and mileage position point, and there are problems such as inconsistent evaluation objects of track health status and inconsistent length of evaluation objects; The third is that the current evaluation indicators of railway track status only reflect the disease information of the railway track section at a certain time, and lack of evaluation indicators that reflect the trend of track status changes

Therefore, the current railway track health status evaluation index system cannot comprehensively evaluate the railway track status, resulting in low reliability in determining the railway track health status, and it is difficult to support the transformation of the track maintenance mode to preventive repair, fine repair, and centralized repair.
