Problems solved by technology

[0003] The existing technology controls the plant protection UAV to perform spraying operations at a fixed flight speed relative to the ground, ignoring the influence of the wind speed and the airspeed of the plant protection UAV relative to the air on the spray width, which may easily cause the plant protection UAV on the round-trip route. Inconsistent spray width and severe uneven dosage

Abstract

The invention provides a spraying control method and device, an aircraft and a storage medium, and relates to the field of unmanned aerial vehicles, and the method comprises the following steps: obtaining an airspeed measurement value of an aircraft relative to air and a flight speed of the aircraft relative to the ground, and when the airspeed measurement value is inconsistent with a set target airspeed, determining an environment wind speed according to the airspeed measurement value and the flight speed, finally controlling the aircraft to fly according to the obtained target flight speed, and executing spraying operation according to the target spraying width. According to the invention, the aircraft can fly at a constant airspeed, the risk of unstable spraying amplitude is reduced, and the spraying uniformity is improved.

Description

technical field [0001] The present invention relates to the field of flight control, in particular to a spraying control method, device, aircraft and storage medium. Background technique [0002] Plant protection drones, also known as unmanned aerial vehicles, can spray pesticides, seeds, powders and other agricultural and forestry plants. During the spraying operation, the spray width of the plant protection drone is directly related to the speed of the plant protection drone relative to the air, ensuring that the plant protection drone sprays at a relatively constant airspeed, which can greatly improve the uniformity of spraying . [0003] The existing technology controls the plant protection UAV to perform spraying operations at a fixed flying speed relative to the ground, ignoring the influence of the wind speed and the air speed of the plant protection UAV relative to the air on the spray width, which may easily cause the plant protection UAV on the round-trip route. ...
