Problems solved by technology

[0004] Most of the current fastener inspections are mainly manual inspections. The patrol workers conduct on-the-spot inspections of the track lines. This method requires the patrol workers to carry a patrol bag with a weight of about 10 kilograms. The patrol length is about 20 kilometers, and the labor intensity is high. , and the working environment is harsh, safety cannot be guaranteed at all, the accuracy of detection is greatly affected by human subjectivity, there are a large number of missed and wrong detections, and effective detection cannot be carried out in remote areas

Abstract

The invention discloses a rail fastener detection device based on machine vision, and relates to the technical field of railways. The rail fastener detection device has the technical key points that the rail fastener detection device comprises a detection beam, a linear array camera assembly, a light source assembly, an image acquisition card, a controller and a memory, wherein the camera assembly and the light source assembly are both installed on the detection beam; the camera assembly is used for collecting an image which contains a rail fastener; the light source assembly is used for providing luminance compensation for the camera assembly; the image acquisition card is used for acquiring image data output by the camera assembly and outputting the image data into the controller; the controller is used for storing the image data into the memory; the controller and the camera assembly are in signal connection; the controller is used for outputting a shutter trigger signal of a certain frequency to the camera assembly to control the camera assembly to carry out image shooting; the controller is also in signal connection with the light source assembly for controlling the luminance of the light source assembly.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a machine vision-based detection device for rail fasteners. Background technique [0002] With the rapid advancement of my country's railway development, as of now, the national railway operating mileage has reached about 120,000 kilometers. The daily railway traffic volume is unprecedented. How to ensure the safe, stable and uninterrupted operation of trains has become an important mission of Chinese railway personnel. [0003] Railway line equipment is the basic equipment of the railway transportation industry. Reasonable maintenance of railway line equipment and timely and effective analysis, prevention and remediation of line equipment diseases are the keys to ensure safe railway transportation. In line maintenance, the daily inspection of fasteners is one of the necessary inspection items. Fasteners are key components for fixing rails on sleepers to maintain gauge and pre...
