On-board variable-concentration dispensing device for a plant protection drone for variable-concentration application

Abstract

The invention provides an on-board variable-concentration dispensing device for a plant protection drone for variable-concentration application, comprising a power module, a control module, a dispensing module and an application module.Compared with the prior art: (1) the proposed variable-concentration dispensing device is capable of effectively responding to large incidence index differences indifferent areas of an operation site, capable of following the principle of ''using a pesticide with a corresponding small concentration for a mild case and a pesticide with a corresponding gret concentration for a severe case'', and capable of achieving'' variable concentration'' application, and the device is dedicated to the mounting of a plant protection drone; (2) ''water tank + pure pesticide tank'' dual-tank independent output control is adopted to realize ''real-time and on-demand.'' blending of different concentrations of pesticide solutions during flight operation of the plant protection drone; (3) a single-chip microcomputer is adopted to control two different media for blending different concentrations of pesticide solutions, which has the advantages of good system responsiveness, high concentration accuracy and the like; (4) ) the variable-concentration dispensing device is more suitable for a mainstream uniform flight operation mode of the existing plant protection drones, and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to a plant protection UAV airborne variable concentration dispensing device for variable concentration spraying. More specifically, the device can synchronously change the spraying amount according to the severity of the target operation area. It belongs to the field of precision agricultural aviation technology to improve the utilization rate of pesticides and realize precise operations. Background technique [0002] my country has 7% of the arable land on the earth, but its chemical fertilizer consumption accounts for 38% of the global total. 95% of human food comes from the soil, and the low utilization rate of pesticides not only causes a lot of waste of resources, but also produces environmental pollution, and even produces phytotoxicity and pesticide residues on crops, and excessive pesticides will seep into the land and eventually enter the human body. Pesticides in food and the environment are ultimately harmful to human ...

Problems solved by technology

[0004] However, the existing variable-variable pesticide application control system is a "variable flow" pesticide application method after all. If the incidence index of different areas of the operation plot is very different, the system will have the problem of "excessive control of minor diseases and insufficient control of major diseases". There is an urgent need to develop a "variable concentration" drug application system following the principle of "light medicine for mild disease and heavy medicine for severe disease" to solve the above problems in the existing technology
