Abstract

The invention provides a heavy haul railway corrugation recognition method, device and equipment based on target detection. The heavy haul railway corrugation recognition method comprises the steps that the time domain waveform of the acceleration of a wheel-rail contact surface when a heavy haul train passes through a heavy haul railway is sampled; coloring the time domain waveform according to an acceleration threshold to obtain a colored image; importing the colored image into a corrugation recognizer, and determining corrugation of the heavy haul railway; wherein the corrugation recognizer is obtained by training a Faster-RCNN model, coloring of a time domain waveform is realized through an acceleration threshold value, the colored image can be caused to the corrugation recognizer, corrugation on the heavy haul railway is recognized through the color of the colored image, target detection different from a deep learning convolutional network is realized, and the detection accuracy is improved. And the corrugation identification accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit and can be applied to the field of heavy-haul railway quality detection, in particular to a method, device, equipment and medium for corrugation recognition of heavy-haul railways based on target detection. Background technique [0002] Rail wavy wear, also known as corrugation, refers to the periodic wavy irregularities on the surface of the rail, and is one of the most urgent problems to be solved in the maintenance and repair of heavy-haul railways. [0003] my country's heavy-haul railways are mainly coal transportation, and heavy-haul railways have been plagued by rail corrugation for a long time. Due to the heavy weight, high traffic volume and high traffic density of trains on heavy-haul railways, rail corrugation is common and develops rapidly, especially in small-radius curves. [0004] When corrugation occurs on the rail, the vertical vibration of the vehicle wheelset increases due...
