Abstract

The invention provides a steel rail defect recognition method based on ultrasonic signals, wherein an ultrasonic signal diagram for detecting steel rail defects is acquired, wherein the ultrasonic signal diagram comprises a plurality of signal points with depth information and width information of a steel rail, the ultrasonic signal diagram is input into a plurality of RGB channels, the pluralityof output images are subjected to feature enhancement and then are overlapped, a superposition image is obtained, an initial recognition neural network is trained on the basis of a preset rectangularframe and the superposition image, and a steel rail defect recognition neural network is obtained. The ultrasonic signals are processed through a plurality of RGB channels to obtain signal points corresponding to the defects so as to determine the outline of the defects, and a plurality of signal points corresponding to the defects are positioned on the basis of a preset rectangular frame, so as to recognize the location and the type of the defects; and the method has the advantages of being more accurate in recognition of the defects and high in recognition efficiency.

Description

【Technical field】 [0001] The invention relates to the field of computer identification of rail defects, in particular to a rail defect identification method, system and electronic equipment based on ultrasonic signals. 【Background technique】 [0002] Ultrasonic rail flaw detection is a commonly used rail defect detection method at present. Ultrasonic flaw detectors are used to detect rail defects. [0003] However, in the existing ultrasonic rail flaw detection method, the ultrasonic wave pattern emitted by the rail is usually analyzed based on the ultrasonic flaw detector, but some normal structures in the rail will also reflect the ultrasound, forming dense echo patterns, such as: bolts Holes, rail joints, holes, wire holes, resulting in frequent false alarms and insufficient accuracy. 【Content of invention】 [0004] In order to overcome the problem of insufficient accuracy in existing rail defect recognition methods based on ultrasonic signals, the present invention pr...
