Train scanning system

Abstract

The invention relates to a train scanning system, comprising a train speed measuring device used for obtaining the current running speed of the train, and a line scanning camera fixedly arranged on the circumference of the running path of the train and capable of continuously acquiring images of the passing train to continuously obtain the longitudinal images of the train, wherein the interval of acquiring images by the line scanning camera is controlled though receiving the running speed of the train acquired by the train speed measuring device so that the images continuously acquired by the line scanning camera can be split jointed to be an integral image passing the line scanning camera part transversely. The system controls spacing interval of acquiring image by the line scanning camera through adopting the train speed so that the line scanning camera can continuously obtain the images of the train in various sections which are split jointed to an integral train image after arranged in sequence, and has clear images.

[0002] With the development of digital technology, the maintenance method of railway vehicles mainly relying on traditional manual tools such as inspection hammers, lanterns and wrenches for railway vehicles can no longer meet the needs of modern people, and this technical inspection method is not only inefficient, labor High intensity, and highly susceptible to factors such as inspector's skills, sense of responsibility, and climate

With the development of railway transportation in the direction of high-speed, heavy-duty, and high-density operation, traditional vehicle inspection methods have become increasingly unable to meet the needs of railway transportation for daily train technical inspection.

However, the existing vehicle dynamic detection equipment collects images in a continuous camera mode when the train is moving. This method not only fails to capture clear and stable images of key parts, but also has disadvantages such as large image alignment deviations and missing images. , the images captured by this continuous camera method will be limited by the analog camera, and the images of the entire train cannot be captured completely, which will easily make the train inspectors miss, falsely detect or detect the train with low efficiency
