Vehicle-mounted drone bridge daily safety detection system and detection method

Abstract

The invention discloses a system and a method for detecting daily safety of a bridge by a vehicle-mounted unmanned aerial vehicle. The system comprises the unmanned aerial vehicle, an image collection system, the vehicle, a control system, and a graphical data analysis system. The system has the advantages that the unmanned aerial vehicle can be used for detecting the surface appearance, curvature (including all surfaces, such as bridge decks, side surfaces and bottom surfaces), and deformation of the bridge within certain speed range; the time of detecting one bridge is greatly shortened, the detection frequency of the bridge is increased, the relative high-frequency detection of the bridge is realized, and the safety early warning capacity of the bridge is improved; the working efficiency is high, the cost is low, and the high-frequency and large-range bridge safety monitoring is realized.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a vehicle-mounted drone bridge daily safety detection system and detection method. Background technique [0002] Bridges are indispensable facilities for road traffic. Among the many road bridges, due to various reasons such as economy, technology, personnel, and society, the bridges have been used for a long time. However, in view of economic conditions and social needs, these bridges are They will still be in use for a long period of time in the future; however, effective monitoring and management measures need to be taken to ensure that these bridges prevent major safety accidents during their use. [0003] In the prior art, bridge inspections are divided into regular inspections, periodic inspections and special inspections. Regular and special inspections of bridges usually refer to close observation and inspection of the main structure with the help of scaffolding or speci...

Problems solved by technology

Regular and special inspections of bridges usually refer to close observation and inspection of the main structure with the help of scaffolding or special equipment. This inspection is considered effective, but it requires high costs, low efficiency, and will affect the normal passage of vehicles on the bridge. , generally requires a regular inspection every 2-6 years; and this kind of visual inspection is mainly aimed at the surface condition of the structure, and there is a problem that internal defects cannot be found; the regular inspection of the bridge is usually implemented by manual inspection on the bridge surface Or use a telescope to observe the bridge structure at a long distance. Due to the limitation of the inspection methods and the number and quality of the practitioners, it is difficult to know the safety status of the bridge accurately and timely by only relying on perceptual knowledge and lack of quantifiable data. Most of the safety inspections are tangible but not real, and there are even disaster cases where the daily maintenance records are classified as Class I bridges and sudden collapses occur. The lack of economical, practical, accurate, efficient, and scientifically quantified bridge safety inspection methods and equipment has caused bridge collapse accidents to become more frequent in recent years. one of the main causes of
