High-speed rail track measuring device and method

Abstract

The invention relates to the field of track detection, in particular to a high-speed rail track measuring device and method. The device disclosed by the invention comprises illuminating lamps, outline measuring instruments and cameras, of which the position relationship is optimized, so that the illuminating lamps can be in team work with the outline measuring instruments and the cameras. The high-speed rail track measuring device disclosed by the invention has the capacity for collecting processing data under the condition of insufficient lighting or dark conditions. Besides, track buckles are recognized, so that strokes are calculated, tracks are positioned, recognition and accurate positioning of problem tracks are realized, and the timely maintenance of the tracks is facilitated.

Description

technical field [0001] The invention relates to the field of track detection, in particular to a high-speed rail track measuring device and a measuring method. Background technique [0002] With the rapid development of high-speed railways in my country, the speed of trains has increased to 300Km / h or even higher, and the safety requirements for vehicle operation are getting higher and higher. With the construction of railway lines, the length of railway tracks continues to increase. The way of measurement can no longer meet the needs of railway maintenance. [0003] Chinese utility model patent "A Rail Side Abrasion Detector" (patent application number: 201120317622.9) discloses a rail side wear detector for measuring the degree of rail wear. The device is simple in structure and easy to operate, but the patent still exists for manual measurement. [0004] At the same time, due to relevant requirements, the train cannot be modified at will. Therefore, during the automatic ...

[0003] Chinese utility model patent "A Rail Side Abrasion Detector" (patent application number: 201120317622.9) discloses a rail side wear detector for measuring the degree of rail wear. for manual measurement

[0004] At the same time, due to relevant requirements, the train cannot be modified at will, so during the automatic measurement, the device connected to the train should be connected without damage, and the general movement of the train on hills, tunnels and other lighting and communication positioning is not good On the road surface, it is difficult to locate the collected information, and the collected images are not clear enough
