System and method for detecting cracks of fasteners of high-speed rails and subways

Abstract

The invention relates to equipment in the field of detection for railway foundation facilities, in particular to a system and a method for detecting cracks of fasteners of high-speed rails and subways. The system and the method for detecting the cracks of the fasteners of the high-speed rails and the subways aim to overcome the shortcoming that an existing fastener technology only can be used for detecting absence and looseness of fasteners but cannot be used for detecting whether the fasteners have cracks or not. The system and the method can be used for quickly detecting absence, partial damage and absence and the cracks of the fasteners of the high-speed rails and the subways in an online manner, and have the advantages of high identification speed, high detailed information embodiment effect, capability of precisely shooting the cracks, and the like. Images are respectively triggered and acquired bilaterally by utilizing the characteristic that the existing fasteners of the high-speed rails and the subways are bilaterally symmetrically mounted along the rails, and in other words, a right image acquisition system can acquire an image of a right fastener while a left photoelectric trigger is triggered by a left fastener of a rail.

Description

technical field [0001] The invention relates to equipment in the field of railway infrastructure detection, in particular to a crack detection system and method for high-speed rail and subway fasteners. Background technique [0002] Railway is a major project related to the national economy and people's livelihood. With the increase of railway mileage and the continuous increase of train speed, it is particularly important for the safety and maintenance of railways, and the demand for monitoring the status of railway infrastructure is also rising sharply. Fasteners are one of the most critical facilities in the railway infrastructure. With the passage of time and the influence of various external factors such as weather, the fasteners will crack, and the decline in the quality of the fasteners will directly affect the safety performance of the railway. . Traditional manual inspection and maintenance can no longer meet the requirements, so various track inspection equipment ...

AI Technical Summary

Problems solved by technology

[0009] In view of the above problems, the object of the present invention is to provide a crack detection system and method for high-speed rail and subway fasteners, which can solve the problem that the existing fastener technology can only detect missing and loose fasteners, but cannot detect whether the fasteners have cracks, and can be used for High-speed rail and subway fastener missing, fast online detection of partial damage missing and cracks, has the advantages of fast recognition speed, high detail information, accurate photography, etc.
