Embodiment 1

[0076] as attached image 3As shown, an embodiment of the bridge inspection system of the present invention specifically includes: an unmanned aerial vehicle system 1 and a ground terminal system 2 . The unmanned aerial vehicle system 1 further includes an unmanned aerial vehicle 10, and an airborne data processing unit 11, a pan-tilt camera 12, a flight control module 16, an obstacle avoidance module 110 and a positioning module 111 mounted on the unmanned aerial vehicle 10, and the ground terminal system 2 further comprises a ground station 20. The UAV 10 performs the first inspection operation on the bridge to be detected under manual operation, and collects bridge surface data through the pan-tilt camera 12, and according to the positioning signal obtained by the positioning module 111 (such as: using GNSS signals, Global Navigation Satellite System, The abbreviation of global navigation satellite system, such as GPS, Glonass, Galileo, Beidou satellite navigation system, ...

Embodiment 2

[0090] An embodiment of the bridge inspection UAV system applied to Embodiment 1, specifically including: UAV 10, and an airborne data processing unit 11 mounted on UAV 10, a pan-tilt camera 12, a first The digital transmission station 13 and the first image transmission station 14. During the automatic inspection operation, the airborne data processing unit 11 sends bridge surface data acquisition control signals to the pan-tilt camera 12 , and the airborne data processing unit 11 sends flight control signals to the UAV 10 . The PTZ camera 12 acquires high-definition data on the surface of the bridge, and the bridge video data collected by the PTZ camera 12 is sent to the first image transmission station 14 through the onboard data processing unit 11, and the bridge video data is sent to the ground by the first image transmission station 14 The end system 2 performs display monitoring. The first data transmission station 13 is connected to the airborne data processing unit 1...

Embodiment 3

[0103] as attached Figure 9 And attached Figure 10 As shown, the bridge inspection UAV system uses a rail car 100 as a carrier, and the rail car 100 includes a driver's cab 101 and a carriage 102 . The ground terminal system 2 is set in the driver's cab 101, the UAV system 1 is set in the compartment 102, and the communication antennas of the second data transmission station 22 and the second image transmission station 23 are set outside the body of the rail car 100 to facilitate data reception .

[0104] The unmanned aerial vehicle 10 is carried on the rail vehicle 100, and the unmanned aerial vehicle system 1 is transported to the bridge to be detected by the rail vehicle 100. On the lines on both sides of the bridge, one or more platforms are solidified with concrete as the fixed take-off and landing platforms of the UAV 10 . When the bridge inspection UAV system is in operation, the rail vehicle 100 arrives at the bridge to be inspected, and the staff first places the...

Abstract

The invention discloses a bridge inspection system. An unmanned aerial vehicle carries out first inspection on a bridge needing detection under the manual operation; a cloud desk camera carried out bridge surface data collection and generates an inspection route based on a positioning signal obtained by a positioning module; an unmanned aerial vehicle carries out inspection automatically based onan inspection route of a writing flight control module; an airborne data processing unit carries out processing based on data sent by an obstacle avoidance module; and the flight control module controls the unmanned aerial vehicle to carry out automatic obstacle avoidance emergency treatment. The cloud desk camera carries out video acquisition and image capturing according to set parameters in theautomatic inspection process; videos collected by the cloud desk camera are sent to a ground terminal system for display; and a ground station performs defect detection and positioning according to the captured images during the automatic inspection process. According to the invention, technical problems that the automation degree is low, the workload is large, the stability of the acquired datais poor, and the safety is low because the existing UAV bridge inspection mode mainly relies on the manual operation for bridge surface data collection by the UAV are solved.

Description

technical field [0001] The invention relates to the technical field of engineering detection, in particular to a system for realizing inspection of bridges such as railways and highways by using an unmanned aerial vehicle. Background technique [0002] By the end of 2017, the national railway operating mileage reached 127,000 kilometers, including 25,000 kilometers of high-speed rail. Calculated based on the proportion of bridges accounting for 52% of the line, there are about 10,000 kilometers of high-speed rail bridges in my country. For example, the accumulative length of the Beijing-Tianjin intercity bridge accounts for 86.6% of the total length of the main line, the Beijing-Shanghai high-speed railway accounts for 80.5%, the Guangzhou-Zhuhai intercity bridge accounts for 94.0%, the Wuhan-Guangzhou Railway Express accounted for 48.5%, and the Harbin-Dalian Railway Express accounted for 74.3%. As a routine operation type in the engineering field, bridge inspection usually...
