Wheel-propelled unmanned aerial vehicle suitable for bridge detection and detection method thereof

Abstract

The invention discloses a wheel-propelled unmanned aerial vehicle suitable for bridge detection and a detection method thereof. The unmanned aerial vehicle comprises a vehicle body, rolling wheels, counterweight wheels, a tail rod, a power device, a battery, a speedometer and a camera. The rolling wheels can protect the unmanned aerial vehicle, enable the unmanned aerial vehicle to be tightly attached to a to-be-detected bridge, enable the distance between the camera and the surface of a structure is fixed, and provide a basis for converting the disease pixel information in the acquired image into a real physical size. The power device on the tail rod can adjust the up-down relative position of the counterweight wheels and the unmanned aerial vehicle body, so that the unmanned aerial vehicle can be flexibly controlled to advance forwards and backwards. The speedometer can record the advancing distance of the rolling wheels of the unmanned aerial vehicle and can record the relative position of the unmanned aerial vehicle and the bridge under the bridge. According to the invention, the UAV can flexibly reach the bridge detection position, and record the quantitative description data of the occurrence of the disease including the disease image, the position of the disease away from the shooting point and the position information of the disease.

Description

technical field [0001] The invention relates to civil engineering and unmanned aerial vehicles intersecting technology, in particular to a wheeled unmanned aerial vehicle suitable for bridge detection. Background technique [0002] With the rapid development of my country's infrastructure construction in recent years, the civil engineering industry has developed rapidly, and a large number of roads and bridges have been constructed, followed by later inspection and maintenance work. The bridge bearing is an important component connecting the upper and lower structures of the bridge. It can be called the throat of a bridge and has a great relationship. Once a disease occurs, if it is not detected and treated in time, it will affect the stress state of the structure and traffic safety. At present, the main method of bridge inspection is manual inspection, which is time-consuming, laborious and will affect traffic. Some bridges built in deep mountains and on the sea are diffic...

AI Technical Summary

Problems solved by technology

However, the existing industrial drones lack design for bridge detection, and cannot accurately obtain the distance between the captured disease and the collection equipment, and when the drone is close to the bridge deck, the stability of the drone itself will be caused by the airflow. Reduced, high-quality images cannot be obtained, and the GPS signal under the bridge is weak, it is difficult for the drone to accurately obtain the location information of the bridge disease by manual control, and the location of the disease is very important information for evaluating the bridge disease
