UAV (unmanned aerial vehicle) system for bridge detection

Abstract

The invention relates to a UAV (unmanned aerial vehicle) system for bridge detection. The UAV system comprises a UAV and a ground station for controlling the UAV, wherein the UAV is connected with the ground station, the UAV comprises a vehicle body, a main camera module for acquiring image data of a to-be-detected bridge, an infrared camera for acquiring auxiliary image data of the to-be-detected bridge and a communication module for being connected with the ground station; the main camera module is arranged at the front end of the vehicle body, the infrared camera is arranged above the vehicle body, and the communication module is arranged on the vehicle body. Compared with the prior art, the UAV can directly reach a to-be-detected position without other auxiliary measures, so that the cost is saved, a detecting worker is not required to perform detection at high altitude, the safety is improved, and road blockage or traffic interruption is not needed.

Description

technical field [0001] The invention relates to a bridge detection technology, in particular to an unmanned aerial vehicle system for bridge detection. Background technique [0002] Bridge inspection is to detect early diseases in time, take maintenance measures before greater damage occurs, control the development of diseases, and ensure the normal use of bridges. There are more than 735,000 existing bridges in my country, and 40% of the bridges in the country have been in service for more than 25 years, requiring regular inspections, regular inspections or special inspections. In the past, bridge inspections used the naked eye or auxiliary tools to detect whether there were cracks, water seepage, steel bar corrosion, concrete shedding, honeycomb pitting, etc. in the main components of the bridge. The distance from the detection target was far away, and there were detection blind spots; at the same time, traditional methods generally used aerial work platforms or ropes. , ...

AI Technical Summary

Problems solved by technology

In the past, bridge inspections used the naked eye or auxiliary tools to detect whether there were cracks, water seepage, steel bar corrosion, concrete shedding, honeycomb pitting, etc. in the main components of the bridge. The distance from the detection target was far away, and there were detection blind spots; at the same time, traditional methods generally used aerial work platforms or ropes. , the choice of tools needs to be determined according to the type of bridge and the ability to block traffic, the efficiency is low and the detection cost is high, and there are safety hazards in high-altitude operations
