Rail comprehensive inspection method based on air-rail double-purpose unmanned aerial vehicle

Abstract

The invention provides a rail comprehensive inspection method based on an air-rail double-purpose unmanned aerial vehicle. Two modes where the unmanned aerial vehicle flies in air and moves along a steel rail are adopted, the flight mode is adopted when quick detection is required for rail fastener missing and the like, the steel rail operating mode is adopted when high-precision detection is required for steel rail and tier surface defects, the two working modes may be arranged and allocated flexibly and switched at any time according to field requirements, and the significant problems of traditional surface inspection mode, such as high cost, poor sensitivity and occupation of normal driving space and other problems, are broken through and solved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method for comprehensive orbit detection using an air-orbit dual-purpose unmanned aerial vehicle. Background technique [0002] At present, the quality inspection of my country's high-speed railway lines mainly includes manual inspection, rail inspection vehicle inspection and other means. The inspection of railway fasteners mainly relies on manual inspection. This method is time-consuming, laborious, and has poor reliability. The time for on-road inspections is insufficient. Especially with the gradual development of my country's high-speed railways, the manual inspection method has been completely unable to adapt to high-speed railways. The need for security checks. The detection of track space geometric dimension information, rail crack degree index, and train power index is mainly a combination of detection methods such as rail inspection vehicles and manual inspecti...

Problems solved by technology

[0004] In the existing method of using UAV to detect track defects, the lack of fasteners can only be detected based on the image data collected in the air, but the precise detection of cracks in rails or sleepers cannot be carried out. Man-machines can only drive on land, and cannot continuously drive along the railway track, so it cannot be applied to the precise detection of the railway track

[0005] The present invention proposes a dual-purpose special UAV for air and rail for safety detection on high-speed rails. The flight mode is used when rapid detection of objects (such as sleeper defects and lack of rail fasteners, etc.) is required, and the rail operation mode is used when high-precision detection of objects (such as rail surface defects and early-stage diseases of sleepers) is required. There are two working modes It can be flexibly arranged according to the needs of the site and switched at any time, breaking through and solving the obvious problems of the traditional ground inspection mode such as high cost, poor flexibility, and occupying normal driving space.
