Train running gear fault diagnosis method and train running gear fault diagnosis device

Abstract

The invention discloses a train running gear fault diagnosis method and a train running gear fault diagnosis device. The method includes acquiring a train speed; adjusting shooting frequency of a camera shooting component to enable the shooting frequency to be matched with the train speed when the train speed exceeding a preset range is judged, and acquiring a train running gear image shot by the camera shooting component according to the adjusted shooting frequency; searching a standard template image corresponding to the train running gear image from a preset database, comparing the train running gear image with a standard template according to a first preset algorithm, marking different positions on the train running gear image when a comparison result indicates difference between the two, and confirming that a train has faults; displaying the train running gear image marked with the different positions. By the train running gear fault diagnosis method, quick and accurate train running gear fault diagnosis is achieved, and a great quantity of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a fault diagnosis method and device for a running part of a train. Background technique [0002] The running part of the train is composed of wheel sets, axle boxes, side frames and traction motors. It is the part of the train running along the line under the action of traction power. The function of the running part is to ensure the safe and smooth running of the train along the track and through the curved track. , Whether there is a difference in the running part of the work is directly related to the smooth flow of train traffic, and is more related to the safety of passengers and drivers. Therefore, the fault diagnosis of the running part must be timely and accurate. [0003] In the fault diagnosis of the running part, the manual diagnosis method is generally used to diagnose the fault of the train, and technicians need to use fault diagnosis equipment to conduct a c...

AI Technical Summary

Problems solved by technology

Due to the need for a large number of technicians and fault diagnosis equipment to diagnose the fault of the train running part, the diagnosis process is also very cumbersome, which not only wastes a lot of human resources, but also leads to low efficiency of fault diagnosis, and it is not timely and accurate enough to diagnose faults
