Urban traffic rail nondestructive testing system and nondestructive testing method based on machine vision

Abstract

The invention relates to an urban traffic rail nondestructive testing system and nondestructive testing method based on machine vision, the urban traffic rail nondestructive testing system comprises abase, a connecting cylinder, a mobile platform, clamping cylinders, two monitoring units, an awning and an embedded column, the lower end of the base is connected with the mobile platform through theconnecting cylinder, and the upper end of the base is symmetrically provided with the clamping cylinders; an embedded column is arranged above the clamping cylinder, and the upper end of the embeddedcolumn is installed on the shielding awning. According to the system, the problems that the distance between the nondestructive detector and the track is increased or decreased and the detection result is influenced due to the fact that the track of the cart often deviates from the preset track because the cart is mostly pushed manually when the cart is pushed, and a certain distance still existsbetween the platform and the track can be solved. The problem that the distance between a nondestructive testing instrument on a cart in a moving state on a platform and a rail can be far, some tinystructural changes on the rail can be difficult to find in time, and potential safety hazards exist in the later period easily due to the fact that inspection is not in place are solved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a nondestructive detection system and nondestructive detection method for urban traffic rails based on machine vision. Background technique [0002] Non-destructive testing refers to the use of changes in thermal, sound, light, electricity, magnetic and other reactions caused by abnormal internal structures or defects of materials without damaging or affecting the performance of the tested object and the internal organization of the tested object. , by means of physical or chemical methods, with the help of modern technology and equipment, to inspect the structure, nature, state and type, nature, quantity, shape, position, size, distribution and changes of the internal and surface of the test piece In the daily maintenance of urban traffic, non-destructive testing is required, and the maintenance of the track also requires non-destructive testing. [0003] In the non-...

AI Technical Summary

Problems solved by technology

[0006] The present invention can solve the problem that when the cart is pushed, the track of the cart often deviates from the predetermined track due to manual push, which causes the distance between the non-destructive testing instrument and the track to increase or decrease, thereby affecting the detection result. And because there is still a certain distance between the platform and the track, the distance between the non-destructive testing instrument on the moving trolley on the platform and the track may be relatively long, and it may be difficult to detect some small structural changes on the track in time. If it is not in place, it will easily lead to problems such as potential safety hazards in the later stage
