Electric multiple units train brake pad intelligent diagnosis system and method

Abstract

The invention discloses an electric multiple units train brake pad intelligent diagnosis system which comprises a rail side basic detection unit, a field control center and a remote control center. The rail side basic detection unit comprises a trigger switch, an image acquisition unit, a rail side control unit and a vehicle number identification module. When an electric multiple units train wheelset passes through the trigger switch, the trigger switch is triggered and coming vehicle information is sent to a sleeper side control unit, and after receiving an instruction of the trigger switch,the sleeper side control unit controls an image acquisition unit to perform image acquisition on a brake pad at a bottom of an electric multiple units train and sends a collected image to a field control center. The field control center recognizes the brake pad at the bottom of the electric multiple units train through the feature mode recognition technology and the edge detection technology, andthen the missing condition of the brake pad is judged through the image comparison technology. According to the invention, the working efficiency is improved, serious consequences caused by manual missing detection, missing repair and errors are effectively prevented, and the operation safety of the electric multiple units train is ensured.

Description

technical field [0001] The invention belongs to the technical field of EMU maintenance, and more particularly relates to an intelligent diagnosis system and method for EMU brake pads. Background technique [0002] Brake pads, brake discs, brake calipers, etc. constitute the basic braking device of the EMU, and the basic braking device is one of the core components of the EMU. The quality of EMU braking directly determines its safety performance. As a key component of the brake system, the health of the brake pad is directly related to the normal operation of the brake system. The deviation of the brake pad during the assembly process or the inclusion of foreign matter between the brake pad and the brake disc during use will also cause the brake pad to wear beyond expectations. On the one hand, this wear will reduce the service life of the brake pad. On the one hand, it will make the braking process unstable and even affect the braking effect. In severe cases, the brake pad...

AI Technical Summary

Problems solved by technology

The former causes excessive wear and affects driving safety, while the latter causes waste and increases the operating cost of EMUs

Although the EMU braking system only accounts for about 15% of the entire EMU cost, due to the large number of brake pads and the heavy maintenance workload, it accounts for more than 40% of the EMU operating cost.
