2D steel rail contour intelligent detection system

Abstract

The invention belongs to the field of contour detection, and particularly relates to a 2D steel rail contour intelligent detection system. The 2D steel rail contour intelligent detection system provided by the invention is used for detecting wear deformation of the steel rail contour, is simple in structure, accurate in measurement, convenient to operate and high in integration, and has very high market value. The 2D steel rail contour intelligent detection system comprises a red linear laser light source used for vertically irradiating on the surface of a detected steel rail and intersecting with the surface of the detected steel rail to form a line; a red light sensitive CCD element used for receiving reflected light irradiated by the red linear laser light source on the surface of the measured steel rail; a microprocessor used for calculating the distance between each photosensitive point and the surface of the measured steel rail by adopting a triangulation ranging method, extracting the surface profile of the measured steel rail and comparing the extracted surface profile of the measured steel rail with a preset profile; and a display used for displaying a comparison picture of the extracted surface profile of the detected steel rail and a preset profile.

Description

technical field [0001] The invention belongs to the field of contour detection, and in particular relates to a 2D rail contour intelligent detection system. Background technique [0002] The 2017 "Sensor and Intelligent System Application International Summit Forum" statistics show that the development of my country's 2D sensor industry is lagging behind. Domestic sensor demand, especially high-end demand, is heavily dependent on imports, and there is a huge gap in localization. Currently, sensor imports account for 80%, and sensor chip imports Accounted for 90%. Among them, there is a serious shortage of high-tech products such as digitalization, intelligence, and miniaturization. The high-end products required by the country's major equipment mainly rely on imports, and the sensors and intelligent instruments required for national security and major projects are often restricted by foreign countries. [0003] At present, the portable 2D rail profile smart sensor has not s...

Problems solved by technology

[0004] Therefore, it is necessary for us to develop a portable 2D rail profile smart sensor product, based on integration, intelligence and machine vision technology, which can replace the current manual caliper method in rail wear detection and reduce labor costs; it is expected to reach more than foreign countries. The advanced level of similar products breaks the foreign monopoly and replaces similar foreign products that are expensive, English interface, and troublesome to maintain, so that the company can seize the opportunity in the increasingly cruel market competition environment and occupy the market in related fields
