Profile variable sprayer and adaptive control method based on plant canopy phenotype

Abstract

The invention discloses a profiling variable sprayer based on plant canopy phenotype and an adaptive control method. The profiling variable sprayer includes a profiling mechanism module A, a profiling mechanism module B, a lifting and sliding module, a profiling bracket module, Liquid supply system, electrical box and detection module; on the basis of dividing the function and mechanism of the profiling sprayer, it adopts a modular and lightweight design. The whole machine has the characteristics of compact structure, lightness and flexibility, easy manufacture and easy maintenance. . The adaptive control method of the profiling variable sprayer automatically collects the ultrasonic echo signal and processes it to obtain the characteristic information of the tree canopy, and then calculates the air volume according to the canopy volume and canopy density phenotype characteristic parameters, The spray volume is calculated by the leaf area density phenotypic characteristic parameters; the profiling control amount calculated by the ultrasonic distance measurement information drives the profiling mechanism to profil, and realizes the automatic profiling of the crown contour, with high profiling accuracy, accurate and efficient spraying, Save medicine and environmental protection, easy to operate.

Description

technical field [0001] The invention belongs to the field of sprayer intelligent equipment, and in particular relates to a profiling variable sprayer based on plant canopy phenotype and an adaptive control method. Background technique [0002] In recent years, my country's forestry industry has developed rapidly, and the planting area and production volume of various forest trees have increased year by year, such as fruit trees, street trees, landscape trees and other forest trees. In order to deal with the problem of forest pests and diseases, sampling and precise spraying technology is used to apply pesticides to trees, which can not only prevent pests and diseases, but also reduce pesticide residues and environmental pollution. [0003] At present, there are three mainstream spraying methods for sprayers. The boom sprayer is mainly used for the prevention and control of plant diseases and insect pests in field crops; the inverted U-shaped sprayer is mainly used for sprayi...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is aimed at the existing profiling sprayer. In terms of profiling mechanism, there are problems such as large and heavy mechanism, poor flexibility, high manufacturing difficulty and high production cost; in profiling control, manual control is generally used Profiling has problems such as poor profiling accuracy, difficult operation, and low efficiency. A profiling variable sprayer based on plant canopy phenotype and an adaptive control method are provided. On the basis of the division of the sprayer's function and mechanism, the modular and lightweight design is adopted. The whole machine has the characteristics of compact structure, lightness and flexibility, easy manufacture, easy maintenance and low production cost; among them, the self-adaptive The control method automatically collects ultrasonic echo signals and processes the tree canopy phenotype characteristic information, calculates the profiling control amount, drives the profiling mechanism to profiling, and realizes the automatic profiling of the canopy contour, with high profiling accuracy, precise and efficient spraying, Save medicine and environmental protection, easy to operate
