Abstract

The invention discloses a fault identification method for the loss of a brake pad of a brake caliper device, which belongs to the field of fault identification of an EMU. The invention aims at the problems of high cost and poor reliability that the existing brake caliper device relies on manual detection for the loss of brake pads. Including collecting the original picture of the brake caliper device; determining the rough positioning target area from the original picture according to prior knowledge, and enhancing the rough positioning target area; using the trained positioning module to determine the brake from the rough positioning target area through the SSD detection network Brake sub-area: Use the post-training recognition module to judge whether the brake disc abrasives are contained in the brake disc sub-area through the improved SSD detection network, and if not, determine that the brake disc is lost. The invention realizes the automatic identification of the failure of the brake sheet loss.

Description

technical field [0001] The invention relates to a fault identification method for the loss of a brake pad of a brake caliper device, and belongs to the field of fault identification of an EMU. Background technique [0002] The brake caliper device is the main part of the basic brake device of the high-speed EMU. It is installed on the bogie part of the vehicle by means of a fixed fulcrum and two lifting lugs. When the vehicle is braking, the brake caliper device relies on the friction between a pair of brake pads on the brake caliper and the brake disc to convert the kinetic energy of the vehicle into heat energy to ensure that the vehicle can stop within a safe distance. When the brake pads of the brake caliper device are lost, the brake caliper device will fail, which will bring potential safety hazards to the normal operation of the EMU. [0003] At present, the detection of the state of the brake pads of the brake caliper device mainly adopts the manual inspection opera...
