Distributed plant protection unmanned aerial vehicle spraying system capable of reducing droplet drift

Abstract

The invention discloses a distributed plant protection unmanned aerial vehicle spraying system capable of reducing droplet drift. The distributed plant protection unmanned aerial vehicle spraying system comprises a network monitoring terminal, an algorithm controller, an airborne environment monitoring device, a ground environment monitoring device, a pressure regulating device, an angle regulating device and a spray head output device; the ground environment monitoring device and the airborne environment monitoring device are respectively used for monitoring the wind speed and direction of anear ground within a large range and a small range to obtain corresponding data of the wind speed, wind direction and wind speed change rate, the corresponding data are transmitted to the network monitoring terminal, approximate pressure and angle parameters for cooperative work of an unmanned aerial vehicle cluster system are unified to be set by the network monitoring terminal and are transmitted to the algorithm controller, detailed regulation data obtained after the parameters are operated by the algorithm controller are respectively transmitted, and the operating pressure and angle are regulated by the pressure regulating device and the angle regulating device to ensure that the spray head output device works according to the required operating pressure and angle, so that droplet drift is reduced, precise pesticide application is realized, and the utilization ratio of the pesticide is increased.

Description

technical field [0001] The invention relates to the field of plant protection drones, and more specifically, to a distributed plant protection drone spraying system that reduces droplet drift. Background technique [0002] Pesticides are an important means to increase agricultural production and reduce natural hazards. At present, drones have the advantages of large operating range, fast and accurate pesticide application, and are considered to be high-efficiency equipment for pesticide spraying. However, due to the influence of factors such as aerial work conditions and environmental airflow, drone spraying operations are prone to fog droplet drift, which will lead to problems such as waste of pesticides, pollution of pesticides, reduced spraying effects, and uneven spraying. Reducing droplet drift and increasing the deposition of pesticides on target crops have become the focus of research in the technical field of plant protection pesticide application in my country. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the means of reducing droplet drift mainly include the spraying particle size, the movement path of the drone, and the dosage form of the liquid medicine. However, because the wind speed in the field environment is changeable, detectable and uncontrollable, For a single spraying method, the effect is poor; for the UAV path (including flight height, direction and speed, etc.), the effect is better, but due to the parameters of the UAV itself and the complex operating environment, by The development process of this method brings greater difficulty and a longer development cycle, and the risk of "crashing" for the UAV itself will also increase
