Abstract

The invention discloses a multi-rotor unmanned aerial vehicle detection platform system for detecting surface cracks of a structural member. The multi-rotor unmanned aerial vehicle detection platform system comprises a multi-rotor unmanned aerial vehicle, a control system and a wireless communication system; the multi-rotor unmanned aerial vehicle for providing a task load and detecting the surface cracks of the structural member comprises a vehicle body, a power system and a sensing system; the control system comprises an upper computer, a lower computer and a hand-held remote control unit; the upper computer is a ground station provided with a main control computer; the lower computer is an execution control module arranged on the multi-rotor unmanned aerial vehicle; the wireless communication system comprises a data transfer radio, a gain antenna and an image transmission module; the main control computer arranged on the ground station transmits information by means of the data transfer radio and controls the flight of the multi-rotor unmanned aerial vehicle through the execution control module arranged on the multi-rotor unmanned aerial vehicle. The platform detecting system is high in degree of automation; by use of a method for detecting the surface cracks of the structural member with the platform detecting system, the working time required by detecting can be effectively saved, and the detection cost is greatly reduced; the multi-rotor unmanned aerial vehicle detection platform and the method are particularly suitable for detection work of cracks on the surface of a large-sized structural member.

Description

technical field [0001] The invention relates to a detection device and a detection method thereof, in particular to a multi-rotor unmanned aerial vehicle detection platform system for detecting surface cracks of structural parts and a method for detecting surface cracks of large structural parts. Background technique [0002] The monitoring of cracks on the surface of structural parts is a work that people often need to implement after the construction project is completed. There are various methods for monitoring cracks on the surface of structural parts. ” technology, announced a detection platform based on quadrotor UAV, on which ultrasonic flaw detector, front camera, upper camera and laser light are installed; After finding the crack, the drone hovers; the staff manually controls the upper and front cameras to fine-tune the location of the crack, and controls the drone to approach. Relying on the relative position of the two rays of light projected on the building by t...

AI Technical Summary

Problems solved by technology

[0003] (1) The degree of automation is low, and the workflow requires a lot of manual operations: such as manually controlling the front and top cameras, controlling the aircraft approaching the crack, especially relying on the relative position of the laser line and the crack to adjust the attitude of the drone. Steps, the staff have undergone extensive training to achieve

[0004] (2) The ultrasonic flaw detector is used as the key equipment to realize the function: under the currently known technical conditions: the weight of the equipment is relatively large, which affects the cruising time of the drone; the price is high, which greatly increases the cost of the technical solution; The power consumption of long-distance flaw detection is large, which seriously affects the single running time of the detection system; the data processing is complex, and ultrasonic long-distance flaw detection is a difficult problem in the current academic and engineering circles
