Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction supervision, and specifically relates to an unmanned aerial vehicle supervision device. Background Art

[0002] In the field of engineering construction supervision, considering that construction sites are spread across various cities, and the management standardization of construction sites is gradually becoming formalized and diversified. In order to realize the mechanization and automation of supervision work, improve the efficiency of supervision work, and ensure the safety of supervision work, the contactless supervision model came into being.

[0003] Contactless supervision is a supervision method that uses drones as flying vehicles and carries mobile filming equipment to take all-round photos of tower cranes, rooftops and other locations, replacing manual on-site filming. In contactless supervision, staff only need to remotely control drones and filming equipment on the ground or in the control room to fully collect, evaluate and record information. It is highly automated, accurate and safe, and can be used in the fields of construction, road, bridge and other engineering supervision.

[0004] Drones are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. They can carry filming equipment, which can improve supervision efficiency and safety. In actual use, drones are affected by factors such as signal interference and power, and there is a risk of crashing. The filming equipment installed on drones is relatively expensive and sophisticated. When a drone falls accidentally, there is a high possibility that the filming equipment will be damaged by collision, increasing the loss. There is a lack of drone supervision devices on the market that can protect filming equipment. Utility Model Content
