Unmanned aerial vehicle hovering in air through air bag and control method

Abstract

The invention relates to an unmanned aerial vehicle hovering in air through an air bag and a control method. When an unmanned aerial vehicle carries out operation, a gas with density lower than air density is inflated into a balloon located above the unmanned aerial vehicle body; a first motor is controlled to enable a first rotating shaft to rotate; an air bag sinks and penetrates through a vegetation opening; the air bag is inflated with air and the air bag is expanded; vegetation below the unmanned aerial vehicle body is hooked so that the unmanned aerial vehicle is prevented from being blown away by wind, which means that a lifting force provided by the balloon and the hook between the air bag and the vegetation below the unmanned aerial vehicle body are utilized to realize the hovering of the unmanned aerial vehicle, at the moment, the rotating speed of the rotor wings of the unmanned aerial vehicle body can be reduced or stopped to save an electric quantity and realize long-timehovering of the unmanned aerial vehicle; and enough hovering time is provided to enable the unmanned aerial vehicle to complete operation, and when the operation is completed, the air bag is deflatedto be separated from hooking with vegetation, the rotor wings are started and the balloon is deflated to realize re-flight.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle hovering in the air through airbags and a control method. Background technique [0002] With the development of drone technology, drones will play an increasingly important role in various industries and fields at home and abroad, and have broad application prospects. At present, due to the limited capacity of the battery of drones, As a result of the duration of the drone's battery life, when the drone is operating in a certain area, such as shooting, the rotor of the drone must continue to rotate to ensure that the drone can hover in the area and perform operations. However, due to the continuous rotation of the rotor, the power in the battery will continue to decrease, so that the drone cannot stay for a long time and cannot guarantee the completion of the operation.

[0002] With the development of drone technology, drones will play an increasingly important role in various industries and fields at home and abroad, and have broad application prospects. At present, due to the limited capacity of the battery of drones, As a result of the duration of the drone's battery life, when the drone is operating in a certain area, such as shooting, the rotor of the drone must continue to rotate to ensure that the drone can hover in the area and perform operations. However, due to the continuous rotation of the rotor, the power in the battery will continue to decrease, so that the UAV cannot stay for a long time and cannot guarantee the completion of the operation.
