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 system for high-speed railway safety detection using an air-rail dual-purpose UAV. The system utilizes two inspection methods of UAV flying in the air and running along the railroad track, taking into account the advantages of fast, flexible and high-precision detection. 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. Two kinds of work The mode 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

[0024] (1) UAV design

[0025] Classified by scale, UAVs can be divided into micro UAVs, light UAVs, small UAVs, and large UAVs. The present invention considers that the actual situation on the railway is not complicated, and its own workload is not large. Through comparative analysis, the four-rotor light UAV selected by the present invention, such as figure 1 shown. Based on the current experimental environment, some main parameters of the UAV in this scheme are listed in Table 1, such as flight height, flight time, wind resistance, etc. The UAV has a long load flight time and low vibration during flight, which is convenient for the measurement of the ultrasonic height sensor in the test, and can carry 2 kg, which can meet the experimental requiremen...

Abstract

The invention provides a high-speed railway safety detection system based on an air-rail dual-purpose unmanned aerial vehicle. The system includes an unmanned aerial vehicle, a remote monitoring center, a ground station, and a wireless communication module. UAVs include rotating blades that provide power for flying in the air and propellers that provide power for driving along the track. The ground station is used to set the flight route of the UAV and control the air flight mode and orbital navigation mode of the UAV. The remote monitoring center is used It is used to monitor the flight status of the drone, analyze the detection information, and conduct emergency response in case of unexpected situations during the driving of the drone. The present invention adopts two patrol inspection modes of unmanned aerial vehicle flying in the air and running along the railway track. The two working modes can be flexibly matched and arranged according to the needs of the site and switched at any time, which breaks through and solves the high cost, poor flexibility, and occupation Normal driving space and other significant problems.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a system for high-speed railway safety detection using an air-rail 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 ins...
