Identification method and device for truck brake shoe breakdown

Abstract

The invention discloses an identification method for truck brake shoe breakdown. The identification method for the truck brake shoe breakdown comprises extracting segmentation characteristics of three angles from a current image; conforming a characteristic region of a truck brake shoe according to the segmentation characteristics of the three angles; extracting truck brake shoe characteristics from the characteristic region of the truck brake shoe in the current image; utilizing the identification method of a support vector machine (SVM) for the truck brake shoe breakdown and calculating characteristics values of the truck brake shoe; judging whether the truck brake shoe failures or not according to the characteristic values and the presetting fault indentification values. The invention discloses an identification device for the truck brake shoe breakdown. Manual-acting faults can be avoided by utilizing the identification device for the truck brake shoe breakdown. The identification rate of the breakdown can be guaranteed. The accidents can be prevented timely. Therefore, operation safety can be guaranteed.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for identifying faults of freight train brake shoes. Background technique [0002] At present, freight car brake shoe braking is the tread braking method commonly used by domestic railway freight cars. The brake shoe brazing on the freight car brake shoe is mainly used to prevent the freight car brake shoe from falling off. Once the brake shoe brazing is lost, the freight car brake shoe will be damaged during the operation It is very likely to fall off, causing brake failure, and what is more serious is that if the brake shoe of the truck just falls off the rail, it will cause a derailment accident. In recent years, the Ministry of Railways has vigorously promoted the fault image dynamic detection system (TFDS) of freight trains to image the key parts of the running trains, and manually browse the images to complete the fault identification. This method of man...

AI Technical Summary

Problems solved by technology

This method of manual fault identification has problems such as low efficiency and unstable recognition rate, which cannot meet the development requirements of train safety operation.

[0003] It can be seen that the use of TFDS in the existing technology for brake shoe fault identification relies too much on manual operations, so the recognition rate of faults cannot be guaranteed, and accidents cannot be prevented in time, so that operational safety cannot be guaranteed.
