Brake shoe abrasion detection device based on image processing technology

Abstract

The invention discloses a brake shoe abrasion detection device based on an image processing technology. Installing carriers are connected with data collecting boxes. Each data collecting box comprises a collecting box casing with a switch cover, a light supplementing system, a camera system and an electric control system, wherein the switch cover is closed and opened on the collecting box casing through a telescopic component, and the light supplementing system, the camera system and the telescopic component are respectively connected with the electric control system. The light supplementing systems are located on two sides of the camera systems, the data collecting boxes are installed on two sides of a track through the installing carriers, the top surfaces of the data collecting boxes are flushed with the top surface of the track, and trigger switches are installed on the inner side of the track and connected with the electric control systems. Compared with the prior art, according to the brake shoe abrasion detection device based on the image processing technology, the image processing technology is adopted to perform on-line non-contact type detection on train brake shoes, shutdown is not needed in the detection process, images of each train brake shoe are accurately collected, the brake shoe abrasion value is obtained by analysis process of captured images, and detection precision is high.

Description

technical field [0001] The invention relates to the field of locomotive and vehicle detection, in particular to a brake shoe wear detection device based on image processing technology. Background technique [0002] Brake shoe is a kind of braking device for railway vehicles, and it is currently widely used as a tread braking equipment on railway freight cars, passenger cars, and subway vehicles. The train uses air pressure to hold the brake shoe and the tread of the wheel tightly, so that friction occurs between the brake shoe and the wheel set for braking. This braking method leads to a high wear rate of the brake shoe. With the rapid increase of railway speed, the requirements for train operation safety are getting higher and higher. In order to ensure the safe operation of trains, the brake shoes in use need to be replaced in time when they wear to a certain thickness. [0003] In the past period of time, because the brake shoe is usually made of cast iron, its price is...

Problems solved by technology

This kind of detection method is parking detection, and the work intensity is high, and the detection accuracy and efficiency are low. It not only wastes manpower and material resources, but also the detection results contain more human subjective judgments, which also causes a large waste of brake shoes.
