An intelligent device and method for automatic target spray flow control of weeding drones

Abstract

The invention discloses an intelligent weeding drone automatic target spraying flow control device and a method. The device comprises a flight master control system, a sensing acquisition processing system, a target spraying flow control system and a power supply device; the flight master control system is used for processing position information, posture information and other parameters of a drone and controlling the drone to fly stably; the sensing acquisition processing system is used for processing acquired field weed image data in real time; the target spraying flow control system is usedfor positioning the direction of a centrifugal nozzle and adjusting the flow of the centrifugal nozzle. The method comprises the steps that a pre-established weed image recognition model is transplanted to an industrial control master board, a USB camera acquires field images in real time and uploads the field images to the industrial control master board for analysis and processing, the presenceor absence, position and area of field weeds are judged according to a processing result, a target pan / tilt is controlled, the direction of the centrifugal nozzle is adjusted, and therefore precise spraying for crops is achieved. The effectiveness of pesticide liquid is improved, and the waste of the pesticide liquid and the environmental pollution are reduced.

Description

[0003] Field weeds can seriously affect crop yields and are difficult to remove accurately due to their uneven distribution

At present, our country still mainly adopts manual weeding, which is laborious, labor intensive and inefficient.

In order to improve agricultural production capacity and production efficiency, some developed countries such as the United States and Sweden have extensively carried out research on ground-walking automatic weeding equipment, but they have not achieved precise positioning, nor can they control the dosage according to the density and area of ​​weeds. , my country's research in this field is still in the initial stage of exploration and research

Utilizing the advantages of UAVs such as easy operation, high efficiency, and good atomization effect, combined with the neural network weed recognition model for low-altitude automatic target weeding equipment research has not yet been found in the field
