Plant protection unmanned plane spraying control system and spraying control method thereof

Abstract

The invention discloses a plant protection unmanned plane spraying control system which performs pesticide spraying according to the flight height and flight speed and a spraying control method. The spraying control method comprises steps of (A) determining pesticide spraying amount, (B) detecting flight speed and flight height of the unmanned plane, (C) calculating the spraying speed, wherein the spraying speed =pesticide spraying amount *flight speed* spraying swath and the spraying swath and the flight height satisfy the function relation: spraying swath=f (flight height), (D) calculating the pumping speed of a water pump and the rotation speed of the centrifugation atomization sprayer according to the spraying speed, (E) transmitting a corresponding signal to a water pump controller and a centrifugation atomization sprayer controller by the unmanned plane navigation controller according to the pumping speed of the water pump and the rotation speed of the centrifugation atomization sprayer. The plant protection unmanned plane spraying control system can automatically regulate according to the flight speed and the flight height of the plant protection unmanned plane, guarantees the effective adhesion amount and the uniform distribution rate of the pesticide droplet on the crop and improves the pesticide application effect.

Description

technical field [0001] The invention relates to the field of agricultural plant protection drones, in particular to a plant protection drone spraying control system and a spraying control method thereof. Background technique [0002] The plant protection drone is a new type of agricultural plant protection equipment. It is mainly composed of spraying equipment carried by drones, and is applied to the task of pesticide plant protection spraying on farmland, forest land and urban green land. The plant protection drone is still in its infancy in my country, but the new spraying method it brings is more than 50 times more efficient than the traditional spraying method, reducing the amount of pesticides by 40%, and reducing soil pesticide residues by 60%. Save 98% of water. Therefore, plant protection drones have extensive market value. [0003] The working method of plant protection drone spraying equipment directly affects the final effect of pesticide spraying. At present, ...

AI Technical Summary

Problems solved by technology

Since agricultural plant protection drones are affected by the manipulation of the operator during the pesticide application process, the constant pesticide spraying speed cannot guarantee the effective adhesion and uniform distribution rate of pesticide droplets on the crops, which in turn affects the effect of pesticide application.
