Abstract

The invention discloses a railway wagon bogie side frame fracture fault image recognition method, and belongs to the technical field of railway wagon bogie safety. The invention aims to solve the problem of poor reliability due to the fact that the side frame fracture detection of the existing railway wagon bogie is carried out in a manual mode. The method comprises the steps of collecting an original gray image of a truck bogie side frame in operation; determining a side frame area of each grayscale image, preprocessing the side frame areas to obtain side frame area sample images, forming a sample image set from all the side frame area sample images, configuring mark information for each side frame area sample image to form a mark file, and forming a sample data set based on the sample image set and the mark file; training the convolutional neural network inception v2 and the convolutional neural network Faster rcnn, and obtaining a trained inception v2 model and a trained Faster rcnnmodel; and processing the to-be-detected image by using the trained inceptionv2 model and the Faster rcnn model to obtain a corresponding side frame state prediction result so as to realize fault identification. The method is used for bogie side frame fracture identification.

Description

technical field [0001] The invention relates to a fault image recognition method for a side frame fracture of a railway freight car bogie, and belongs to the technical field of railway freight car bogie safety. Background technique [0002] The fracture fault of the side frame of the railway freight car bogie is a fault that endangers the traffic safety. If the fracture location cannot be dealt with in time before the fault occurs, safety accidents will easily occur. [0003] At present, in detecting the fracture of the side frame, it is necessary to obtain an image of the side frame first, and then manually detect the image to determine whether the side frame is broken. In the process of inspecting a large number of images, the inspectors are prone to human factors such as fatigue and omissions, which may cause missed inspections and wrong inspections. Therefore, the reliability and efficiency of this judgment method will be affected. Affect the driving safety of trucks. ...
