Rail wear measurement device and its grinding strategy based on machine vision

Abstract

The invention provides a steel-rail wear measurement device based on machine vision, which comprises a main control panel, a power panel, a laser control panel, and a video panel. The power panel is used for providing a stable direct-current voltage for the main control panel, the laser control panel and the video panel. The laser control panel is electrically connected with two high-power lasers. The video panel is electrically connected with two CCD cameras. The main control panel is connected with the power panel, the laser control panel, and the video panel, and used for controlling the on-off and intensities of the two high-power lasers and controlling the shooting actions of the two CCD cameras. The invention also provides a grinding strategy method for steel-rail wear according to the measurement device. According to a planned grinding quantity, a proper grinding speed of a steel-rail grinding car, the grinding power, and the motor distribution of different angles are calculated, and the steel rail is grinded. The steel-rail wear measurement device based on machine vision has the beneficial effects that the planned grinding area of the steel rail on side can be calculated according to different zones, and shortcomings of large amount of labor, poor environment, low efficiency and the like of the measurement mode of manual and mechanical contact can be overcome.

Description

technical field [0001] The invention relates to the field of rail measurement, in particular to a machine vision-based rail wear measurement device and a grinding strategy method thereof. Background technique [0002] The railway is the main artery of national transportation, which undertakes more than 70% of the passenger and freight tasks in our country. Whether the rails are in good condition directly affects whether the train can run safely, smoothly and uninterruptedly at the specified speed. The high-speed, heavy-load, and high-density operation of the train accelerates the wear of the rail. When the wear exceeds a certain limit, on the one hand, the contact relationship between the rail and the tread of the train wheel will be changed, the running resistance of the train will be increased, and the wear of the rail will be further accelerated, which will have a great impact on driving safety; Severe swaying occurred, seriously affecting the comfort of passengers.

Problems solved by technology

The grinding of high-speed railways mainly meets the quality requirements by increasing the number of grinding times. There is a large amount of unnecessary grinding, which not only increases the cost of rail grinding, but also shortens the service life of the rails.
