Problems solved by technology

However, the flight spraying method of the "bow"-shaped route has the following disadvantages: in the course of each turning and turning, it is necessary to decelerate first and then turn, and then start straight-line acceleration and constant speed after the turning is successful. In such a reciprocating process, the aircraft needs to go through multiple deceleration and acceleration processes, which consumes a lot of electricity or fuel, and wears out the internal components of the aircraft body.

Embodiment Construction

[0016] Such as figure 2 The spraying method of the plant protection unmanned aerial vehicle shown includes the method that the main body of the aircraft carries the spraying mechanism to fly over the designated area and sprays the liquid medicine downward, and also includes the following execution steps of the flight route of the main body of the aircraft:

[0017] S1. Divide the specified area into at least one rectangular area;

[0018] S2. Fly in a spiral rotation along the periphery of one of the rectangular areas, and the interval between adjacent flight trajectories is the spraying radius;

[0019] S3. After the main body of the aircraft flies to the middle of the rectangular area, it stops spraying the liquid medicine or flies straight to the side of another rectangular area closest to the rectangular area.

[0020] By improving the flight path of the main body of the aircraft, the method of spiral rotation is adopted, such as figure 2 As shown, the method of formin...

Abstract

The invention discloses a spraying method for a plant protection unmanned aerial vehicle (UAV). The spraying method includes a method in which an aircraft body carries a spray unit, flies to a designated area and spraying a soup downward, and also comprises executing steps of a flight route of the aircraft body which are an S1 step of dividing the designated area into at least one rectangular area; an S2 step of performing spiral rotation flight along the surrounding of one rectangular area, with an interval of adjacent flight paths as the spraying radius; and an S3 step of stopping spraying the soup after the aircraft body flies to the central portion of the rectangular area, or flying straightly toward a closest side of the rectangular area to another rectangular area. The invention is capable of reducing the turning of the aircraft body and reducing the loss.

Description

technical field [0001] The invention relates to a plant protection drone, in particular to a spraying method of a plant protection drone. Background technique [0002] The plant protection UAV is an unmanned aircraft used for agricultural and forestry plant protection operations. It generally includes the main body of the aircraft and the spraying mechanism installed on the main body of the aircraft. The spraying operation is realized through ground remote control or GPS flight control. It can spray chemicals, seeds, Liquids such as powders. [0003] For spraying tasks in designated areas, such as figure 1 As shown, the flight route of the plant protection UAV is usually set in a "bow"-shaped turning flight, that is, the designated area is divided into multiple adjacent rectangular areas, and then each rectangular area is sprayed back and forth to make the spray out The liquid medicine spreads over the designated area. However, the flight spraying method of the "bow"-shap...
