Pesticide spraying drifting prevention method and system of pesticide spraying unmanned aerial vehicle and storage medium

Abstract

The invention discloses a pesticide spraying drifting prevention method and system of a pesticide spraying unmanned aerial vehicle and a storage medium. The pesticide spraying drifting prevention method comprises the steps of obtaining wind speed information of the unmanned aerial vehicle during pesticide spraying; establishing a relational database of the wind speed information and a spraying pressure, and matching the spraying pressure of a nozzle according to the acquired wind speed information through the database; establishing a fogdrop particle stress model, and analyzing fogdrop position information according to the fogdrop particle stress model; comparing and analyzing the fogdrop position information to obtain a deviation ratio, and judging whether the deviation ratio is greater than a preset deviation ratio threshold value or not; and if yes, calculating a drifting distance of the fog drops, generating correction information, and correcting the motion trail of the fog drops through the correction information.

[0002] Agriculture is the lifeblood of national economic development, and agricultural aerial spraying is an effective measure to ensure national ecological security. In agricultural applications, UAVs have unique operating technology characteristics and have gradually become a new tool for agricultural production, especially pesticide spraying. UAVs have adaptability With the advantages of strong capability, high operating efficiency, saving labor, saving resources and protecting the environment, it has a very good development space in the field of agricultural aviation. This long-distance operation mode also avoids long-term contact between operators and pesticides. The technology also improves the uniformity of pesticide spraying, reduces the waste of pesticides and water resources, ensures the appropriate amount of pesticide spraying, and improves the efficiency of pesticide spraying. However, drones are often restricted by the weather when performing aerial plant protection operations. Natural wind will affect the droplet deposition and droplet drift, resulting in serious droplet drift, heavy spraying and missed spraying, which will reduce the operation effect, and the drifting pesticide droplets will easily cause environmental pollution
