Unmanned aerial vehicle pesticide spraying system and method based on traverse waypoints

Abstract

The invention relates to an unmanned aerial vehicle pesticide spraying system and method based on traverse waypoints and belongs to the technical field of unmanned aerial vehicle pesticide spraying. The unmanned aerial vehicle pesticide spraying system comprises an unmanned aerial vehicle and further comprises a power supply, a control unit, a navigation unit and a pesticide spraying unit which are carried on the unmanned aerial vehicle. The pesticide spraying unit comprises a pesticide box, a spray nozzle communicating with the pesticide box and a flow adjustment valve arranged between a pesticide box pesticide outlet and a spray nozzle pesticide inlet. The power supply is electrically connected with the control unit, the navigation unit and the pesticide spraying unit and supplies power for normal work of the control unit, the navigation unit and the pesticide spraying unit. The navigation unit outputs a navigation signal to the control unit which outputs a control signal to the pesticide spraying unit to control a pesticide spraying state and comprises a processor. The processor is used for controlling the pesticide unit to conduct preset-time pesticide spraying when the unmanned aerial vehicle flies to a preset hovering position. The unmanned aerial vehicle pesticide spraying system can well solve the technical problem, namely the problem that unbalanced pesticide spraying is caused by the uncertain flying speed and attitude in the pesticide spraying process, existing in existing continuous pesticide spraying.

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
