Method and system for identifying falling fault of rail wagon hook lifting rod

Abstract

The invention discloses a method and system for identifying a falling fault of a rail wagon hook lifting rod, and belongs to the technical field of freight train detection. The objective of the invention is to solve the problem of low accuracy of truck hook lifting rod falling fault detection by use of an existing method. The specific implementation process of the method comprises the following steps: step 1, collecting a truck image, determining a hook lifting rod region from the collected truck image, extracting a hook lifting rod region image, and constructing a training set by utilizing the extracted hook lifting rod region image; 2, constructing a deep learning model, and training the constructed deep learning model by using the training set to obtain a trained deep learning model; and step 3, inputting a to-be-detected image into the trained deep learning model to obtain an output result of the deep learning model, and processing the output result by using an image processing method to obtain a judgment result of the falling fault of the hook lifting rod. The method and system are mainly used for detecting falling of the hook lifting rod.

Description

technical field [0001] The invention relates to a method and system for identifying a fall-off fault of a rail freight car hook lifter, and belongs to the technical field of freight train detection. Background technique [0002] The hook lifter is a part for uncoupling the couplers of two connected cars. When freight cars are marshalling at the station, it is often necessary to turn the hook lifter to unmarshal the vehicles. If the hook lifter fails, it will affect the marshalling of the train. operate. In previous inspections, manual inspections were usually used. This detection method is affected by human subjective factors, and when artificial fatigue occurs, it will cause false detection and missed detection of faults, resulting in low accuracy of fault detection. [0003] Therefore, it is of great significance to carry out automatic fault detection on trucks. But there is no automatic fault detection method at present. Although the detection can be realized through ...
