An unmanned aerial vehicle spraying system and spraying method based on traversing waypoints

Abstract

The invention relates to a drone spraying system and a spraying method based on traversing waypoints, and belongs to the technical field of drone spraying. Among them, the UAV spraying system includes the UAV and the power supply, control unit, navigation unit and spraying unit mounted on the UAV. The spraying unit includes a medicine box, a nozzle connected to the medicine box, and a The flow regulating valve between the drug port and the drug inlet of the nozzle; the power supply is electrically connected to the control unit, the navigation unit and the spray unit to supply power for their normal work. The navigation unit outputs navigation signals to the control unit, and the control unit outputs to the spray unit. The control signal is used to control the spraying state; the control unit includes a processor, which is used to control the spraying unit to spray for a preset duration when the drone flies to a preset hovering position. The UAV spraying system can well solve the technical problems existing in the existing continuous spraying, that is, the problem of unbalanced spraying due to uncertain flight speed and attitude during the spraying process.

Description

technical field [0001] The invention relates to a spraying device and a spraying method thereof which work in cooperation with an unmanned aerial vehicle, in particular to an unmanned aerial vehicle spraying system and a spraying method based on traversing waypoints. Background technique [0002] Due to the characteristics of high efficiency and no damage to crops in the UAV plant protection operation mode, and with the development of UAV technology, especially its flight stability, autonomy and power endurance increase, it has replaced the traditional artificial plant protection as a method. , has become the main method of plant protection operations. [0003] The patent document with publication number CN106448105A discloses a fixed-point spraying drone, including a rotor drone and a power supply, a drug container, a drug pump and a drug nozzle mounted on the rotor drone through a platform. During the working process, the chemical pump sprays the chemical stored in the ch...

AI Technical Summary

Problems solved by technology

During the working process, the chemical pump sprays the chemical stored in the chemical container to the crops through the chemical nozzle. However, it continuously sprays the area to be sprayed along the route, and the spraying amount at different positions is likely to vary with the speed and attitude of the ship. Adjustment and change, that is, it is not easy to control the amount of spraying, the place where the spray is too much will easily lead to insufficient absorption of the crops and cause pollution to the environment, and the place where the spray is small will easily cause the spraying effect to fail to achieve the desired goal
