Abstract

An intelligent detection system for a fault of a railway wagon running part relates to the field of fault detection. By the intelligent detection system, the problems that a vehicle detection means ofan operation site of an existing railway dumper still takes artificial detection as main, an artificial detection mode is easy to cause detection leakage and the vehicle detection operation quality and efficiency is difficult to guarantee are solved. A pair of wheel sensors are used for detecting an axial distance, a control unit is used for obtaining vehicle model information according to the axial distance so as to judge whether a vehicle is a wagon, the system enters a vehicle pickup state if the vehicle is the wagon, another pair of wheel sensors are used for detecting a vehicle speed andcontrolling shooting frequencies of three groups of image acquisition equipment according to the vehicle speed so as to perform image acquisition on the bottom and two sides of the railway wagon, radio-frequency reading equipment is used for identifying vehicle number information of the railway wagon, and an automatic fault identification unit employs a deep learning identification algorithm to perform fault identification on an wagon image of the corresponding vehicle number and warn at the fault so as to achieve fault detection of the railway wagon running part. The intelligent detection system is used for detecting the fault of the railway wagon running part.

Description

technical field [0001] The invention relates to a system for detecting faults on running parts of railway wagons, belonging to the field of fault detection. Background technique [0002] Railway dumper refers to a large-scale mechanical equipment used to dump railway open car (freight car) bulk materials. A loading and unloading machine that can flip or tilt rail vehicles to unload; after the bulk material on the railway open car is dumped by the railway dumper, the railway dumper puts the railway open car on the railway track again, in order to prevent the railway open car from During the dumping process, the parts on the running part of the vehicle are missing or damaged. It is necessary to detect the running part of the truck in the railway dumper operation site, find out the hidden troubles and deal with them in time; at present, the vehicle detection method in the railway dumper operation site is still manual. Inspection is the main method, and the disadvantages of man...
