Anti-drifting intelligent control system for pesticide spraying of plant protection unmanned aerial vehicle and control method thereof

Abstract

The invention discloses an anti-drifting intelligent control system for pesticide spraying of a plant protection unmanned aerial vehicle and a control method of the anti-drifting intelligent control system, and belongs to the technical field of agriculture. A pause/start pesticide spraying wind speed threshold real-time measurement module is added in a flight control program of the plant protection unmanned aerial vehicle; when the real-time monitored wind speed is higher than the real-time pesticide spraying pause wind speed threshold value, the plant protection unmanned aerial vehicle automatically closes the spray head, flies back to the spray head closing point and hovers, and pesticide spraying operation is restarted when the wind speed is lower than the real-time pesticide spraying starting wind speed threshold value. The invention provides a weighted calculation formula, in the formula, two real-time monitoring parameters (air humidity and the distance between the air humidity and a pesticide drift boundary line) and five parameters related to crops, target pests, pesticide spraying operation and the like are called and used for calculating a pesticide spraying pause/start wind speed threshold changing in real time in the operation process of the unmanned aerial vehicle. The wind speed is compared with the actually measured wind speed, the pesticide spraying operation is intelligently, accurately and efficiently controlled, the pesticide liquid drifting harm is avoided, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to an intelligent control system for spraying pesticides and anti-drift of a plant protection drone and a control method thereof. Background technique [0002] Plant protection drone spraying pesticides to prevent pests and weeds has outstanding advantages such as super high efficiency, strong assault ability, wide adaptability, labor saving, safety to people and the environment, and small mechanical damage to crops. Therefore, the market size of drone plant protection The rapid expansion year by year has become an important direction for the development of my country's unmanned agriculture. my country's drone plant protection operations are not self-promotion, and there is a strong demand for the improvement and upgrading of plant protection drone spraying technology in production. [0003] At present, one of the key bottlenecks restricting the development of the U...
