Unmanned aerial vehicle with follow-up lighting function for bridge detection

Abstract

The invention discloses an unmanned aerial vehicle with a follow-up lighting function for bridge detection; the unmanned aerial vehicle comprises an unmanned aerial vehicle system, synchronous rotation control devices are symmetrically mounted at the upper end of the unmanned aerial vehicle system, holders are mounted at the upper ends of the synchronous rotation control devices, and a distance measurement module and image acquisition equipment are mounted on one side of the holder side by side; and a spotlight is arranged on the holder on the other side. The synchronous rotation control devices are added, the deflection angle of the spotlight control holder can be calculated according to the control signal of the control holder of the image acquisition equipment, the observation point distance measured by the distance measurement module and the installation distance between the spotlight and the image acquisition equipment, and the workload of bridge detection personnel is reduced while the image acquisition quality is improved.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle with a follow-up lighting function for bridge detection. Background technique [0002] Bridges are an important part of public transportation, and their safety is related to the safety of life and property of the general public. Regular inspection of bridges is of great significance for discovering potential safety hazards. Common problems that affect the safety of bridges include: body cracking, surface peeling, exposed steel bars, important fasteners loose or severely corroded, and important parts are lost. At present, there are many methods for bridge safety inspection. For real-time monitoring, this method often needs to set up monitoring platforms at multiple locations on the bridge, which requires a large initial investment, and there are many locations where it is not convenient to set up monitoring platforms, and the later maintenance is also extrem...

[0002] Bridges are an important part of public transportation, and their safety is related to the safety of life and property of the general public. Regular inspection of bridges is of great significance for discovering potential safety hazards. Common problems that affect the safety of bridges include: body cracking, surface peeling, exposed steel bars, important fasteners loose or severely corroded, and important parts are lost. At present, there are many methods for bridge safety inspection. For real-time monitoring, this method often needs to set up monitoring platforms at multiple locations on the bridge, which requires a large initial investment, and there are many locations where it is not convenient to set up monitoring platforms, and the later maintenance is also extremely inconvenient, such as the bottom of the bridge or the slope. The columns of the cable-stayed bridge are higher; one way is to use the bridge inspection vehicle to carry the inspectors to carry out manual inspection of the bridge, which takes a long time and the cost of the inspection vehicle is high; the other method is to use drones for inspection. Can reduce detection cost and improve detection efficiency

[0003] Although most UAVs are equipped with obstacle avoidance equipment or additional anti-collision equipment, in order to ensure the safety of UAVs during detection, high-magnification zoom cameras are often used for long-distance detection, and bridge deck detection is relatively convenient. , when detecting the bottom of the bridge, the UAV is mostly under the side of the bridge, and the zoom camera placed above the UAV is used to take pictures of key locations or suspicious locations and send them back. In some dark conditions, the zoom camera The photos taken do not clearly identify whether there is a security risk at the location
