Self-adaptation spraying air capacity adjusting device based on plant characteristics and method

Abstract

The invention discloses a self-adaptation spraying air capacity adjusting device based on plant characteristics and method. The device comprises five-finger sprayers, a draught fan, a hose, electromagnetic valves, flow guide pipes, a hose, an air nozzle, a laser sensor, a touch screen, a radar speed sensor, an ARM Cortex controller and an embedded PC / 104 computer, wherein the draught fan is driven by PTO; the hose enables the five-finger sprayers and an air outlet of the draught fan to be connected; the electromagnetic valves are arranged on the flow guide pipes and are used for controlling air capacity of the five-finger sprayers; the flow guide pipes are connected with the electromagnetic valves to output air; the hose are connected with all the flow guide pipes; the air nozzle enables a converge hose on the left and a converge hose on the right to be connected; the laser sensor is installed at the front end of a spraying machine; the touch screen is installed in a cab; the radar speed sensor is installed at the bottom of the spraying machine; the ARM Cortex controller is used for controlling the air capacity and variations; the embedded PC / 104 computer is connected with the touch screen, the laser sensor, the speed sensor and the ARM Cortex controller. According to the device, all the five-finger sprayers can perform self-adaptation air capacity adjustment according to plant characteristics in corresponding areas, reduce fog drop drifting for areas with sparse plants, increase the penetrability of fog drops on areas with dense plants and branches and leaves and increase the attachment rate of fog drops inside the plants.

Description

technical field [0001] The invention relates to a spray air volume adjustment device, in particular to an adaptive spray air volume adjustment device and method based on plant characteristics. Background technique [0002] Plants such as fruit trees and flowers show different appearance characteristics during the growth process, and the density of their branches and leaves changes with time and seasons. Air-driven sprayers designed based on infrared and ultrasonic target technology are widely used, but due to the fact that they are easily affected by the detection environment during actual operation, such as temperature, humidity, spraying airflow, etc., the accuracy of the detection results is reduced. , thus affecting the effect and efficiency of its spraying. The air-driven spraying system using this type of sensor cannot accurately obtain the detailed characteristics of each part of the plant target, and there is less consideration for the adaptive adjustment of the spr...

Problems solved by technology

However, in this method, when the area of ​​the air inlet becomes smaller, the load of the fan increases, and the air output decreases instead, resulting in a decrease in the efficiency of the fan.
