Plant protection drone spraying method and system

Abstract

The invention discloses a plant protection UAV spraying method and system, a plant protection UAV spraying system, comprising: a plant protection UAV and a ground station; the plant protection UAV includes a flight module, a flight control module and a spraying module, and spray The module includes water tanks, water pumps, flow meters and sprinklers connected in sequence; the ground station determines the target spraying amount of the crops to be sprayed and the target flight speed of the plant protection drone according to the information of the operation area, the information of the crops to be sprayed and the information of the plant protection drone and the flight line information of the plant protection drone and send it to the flight control module; the flight control module controls the flight module to fly according to the flight line and target flight speed, and controls the speed of the water pump and the flight speed of the flight module by monitoring the flow information of the flowmeter , so that the chemical solution loaded in the water tank is sprayed out from the nozzle according to the target spraying amount. The spraying method and system of the plant protection drone disclosed by the present invention can finely control the spraying operation of the plant protection drone.

Description

technical field [0001] Embodiments of the present invention relate to UAV technology, and in particular, to a plant protection UAV spraying method and system. Background technique [0002] With the development of UAV technology, various types of UAVs have been widely used in various industries, which improves the work efficiency of various industries and saves the consumption of manpower and material resources. As a new type of pesticide spraying equipment, plant protection drones have also developed rapidly in recent years. [0003] Compared with traditional manual spraying, plant protection drones greatly save the required manpower, and even after setting the corresponding automatic spraying program, unattended automatic spraying can be realized. The liquid is more uniform, the liquid consumption is less, and the pesticide residue can be reduced. Compared with the aerial spraying of large agricultural aircraft, the cost of plant protection drones is lower, and the sprayi...

Problems solved by technology

[0004] However, plant protection drones generally use high-concentration, fine spray, and low-capacity ultra-low-volume spray technology. There are still some errors in the spraying control of man-machine
