specific Embodiment approach 1

[0039] Specific implementation mode one: the following combination figure 1 with figure 2 To illustrate this embodiment, the fault image recognition method for closing a door handle of a railway wagon knuckle plug in this embodiment includes the following steps:

[0040] Step 1. Establishing a training set of image data of a knuckle plug doorknob;

[0041] Due to the harsh conditions when the truck is running, the parts will be affected by natural conditions such as rainwater and muddy water, and the oil stains on the body will affect the grayscale and shape changes of the corner plug handle in the image. Therefore, when collecting images, it is necessary to ensure that the images of the parts are diverse. and complexity, in order to find more stable features during model training, which can improve the generalization ability and accuracy of the model. And according to the state of the fault in the image where the knuckle plug doorknob is not in the correct position, the co...

Abstract

The invention discloses a recognition method for a closing fault image of a wagon angle cock handle, belongs to the field of railway image processing, and aims to solve the problems of false detectionand missing detection of an existing fault detection method for wagon angle cocks. The method comprises the following steps: step 1, establishing an angle cock handle image data training set; step 2,building a Faster RCNN network model; step 3, training the network model: inputting the training set in the step 1 into the Faster RCNN network module in the step 2 for training; and step 4, carryingout fault prediction on the vehicle passing image of the wagon angle cock handle by using the trained Faster RCNN network model.

Description

technical field [0001] The invention belongs to the field of railway image processing and relates to the fault detection of the knuckle plug door handle of the freight car. Background technique [0002] Angle cocks are control valves for connecting and cutting off the air between locomotives, locomotives and vehicles, and vehicles. Closing the angle cocks will result in short air exhaust time and weak braking force for freight cars. The closer the closing position of the knuckle plug door of the same train is to the locomotive, the greater the danger; the greater the traction weight, the greater the danger; the higher the running speed, the greater the danger; the longer the downhill, the greater the danger. Also bigger. In the past, there were two detection methods for this fault detection, manual detection and traditional image processing. Manual detection will cause fatigue and inattention, resulting in false detection and missed detection, which will greatly affect dri...
