Pesticide spraying method and system

Abstract

The invention discloses a pesticide spraying method and system. The method comprises the steps that the actual wind speed of flight position of an airplane is obtained; the position of the airplane is obtained, wherein the position of the airplane comprises the flight height and latitude and longitude coordinates of the airplane; the actual landing point of pesticide is calculated according to the actual wind speed and the position of the airplane; the actual landing point of the pesticide is the actual landing position of the pesticide affected by wind power; the landing point offset of the pesticide is calculated according to the actual landing point of the pesticide, wherein the landing point offset of the pesticide is the deviation of the actual landing point relative to a planned landing point, and the planned landing point is the position where the pesticide landed under the windless condition; a flight path of the airplane is adjusted according to the landing point offset of the pesticide, and the landing point offset of the pesticide is smaller than a set threshold value. According to the technical scheme, by means of the mode of calculating the effect of wind so as to change the flight path, it is guaranteed that the pesticide can land on a predetermined region, and waste of the pesticide is reduced.

Description

technical field [0001] The invention relates to the field of agricultural automation, in particular to a pesticide spraying method and system. Background technique [0002] In the prior art, automatic spraying of pesticides mostly uses drones for automatic spraying. Before spraying, pre-set the spraying area to plan the flight route. The drone flies according to a fixed flight route to realize automatic spraying. However, pesticides are easily disturbed by various factors in the process of floating in the air, so that the pesticides cannot be sprinkled on the predetermined area. Contents of the invention [0003] In order to ensure that the pesticide can fall on a predetermined area, the present invention provides a pesticide spraying method that changes the flying direction according to the wind speed and direction. [0004] To achieve the above object, the present invention provides the following scheme: [0005] A pesticide spraying method, comprising: [0006] Obt...
