The invention relates to the technical field of bridge detection, in particular to a bridge structure detection data collection method and an unmanned aerial vehicle system. The bridge structure detection data collection method comprises the steps of planning a data receiving point and an image acquisition point according to a bridge structure detection requirement, and controlling an unmanned aerial vehicle to fly according to a planned flight path; when the unmanned aerial vehicle flies to one image acquisition point, acquiring image data of the image acquisition point; under the condition that the unmanned aerial vehicle flies to one of the data receiving points, controlling the unmanned aerial vehicle to hover, and controlling the data collector to establish wireless connection with a sensor of the data receiving point, so that the data collector receives a data stream from the sensor; and under the condition that data transmission is completed, controlling the data collector to be disconnected from the sensor in a wireless mode; according to the bridge structure detection data collection method, the types of data which can be collected by the unmanned aerial vehicle and is used for bridge detection are expanded; and the accuracy of bridge structure health state evaluation can be improved.
Description
technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge structure detection data collection method and an unmanned aerial vehicle system. Background technique [0002] As a large-scale civil engineering structure, due to load, fatigue and corrosion, material aging, lack of timely maintenance and excessive traffic, bridge structures will inevitably be damaged during the service period, affecting the service life, and even causing sudden accidents. disaster. The purpose of bridge structure inspection / monitoring is to regularly / continuously measure the operating status data of the bridge structure, extract indicators that characterize the structural performance, and realize disease diagnosis and safety assessment, so as to take timely measures to prevent bridge collapse or local damage, as well as guarantee and The purpose of prolonging the service life of the bridge. Generally speaking, the data that needs to be coll...
