A self-propelled intelligent sprayer based on image processing

Abstract

The invention discloses an intelligent self-propelled sprayer based on image processing. The intelligent self-propelled sprayer comprises a frame, a chassis, a power mechanism, a transmission mechanism, two caterpillar band walking mechanisms, a spraying mechanism and a control system. The frame is fixed above the chassis, the power mechanism and the transmission mechanism are installed on the chassis, and the two caterpillar band walking mechanisms are installed on the two sides of the chassis respectively; the spraying mechanism is installed on the frame and comprises a pesticide storage tank, a pesticide conveying system, a nozzle bearing platform, a centrifugal pump and a stepping motor, and an output shaft of the stepping motor is connected with the nozzle bearing platform in a driving mode and drives the nozzle bearing platform to rotate; the control system comprises an image collecting device and a master controller, the image collecting device is installed at the front end of the frame, and the master controller obtains image information of the front of the sprayer through the image collecting device, obtains information of a region to be sprayed through analysis according to the image information, and controls the power mechanism, the centrifugal pump and the stepping motor to act according to the information of the region to be sprayed.

Description

Technical field [0001] The invention relates to the technical field of plant protection spray machinery, in particular to a self-propelled intelligent sprayer based on image processing. Background technique [0002] my country’s plant protection machinery has a low degree of automation, and the amount of pesticide sprayed cannot be intelligently sprayed according to the growth of the plants, nor can it achieve automatic positioning, automatic walking, and automatic adjustment of spray volume. At present, for the prevention and control of diseases and insect pests of crops with narrow row spacing and large areas of tall plants such as corn, wheat, soybeans, cotton and sorghum, most rely on manual or electric sprayers to spray fields or plants, which not only causes environmental pollution, but also causes drugs. Resources are wasted, and in the environment of drug drop drift and high temperature operation, it is easy to cause poisoning and heat stroke of the operator, resulting in...

Problems solved by technology

[0002] my country's plant protection machinery has a low degree of automation, and the amount of sprayed pesticides cannot be intelligently sprayed according to the growth of plants, nor can it realize the functions of automatic positioning, automatic walking, and automatic adjustment of spraying volume of the sprayer.

At present, for the prevention and control of diseases and insect pests of crops with narrow row spacing and large areas of tall plants such as corn, wheat, soybean, cotton, and sorghum, most of them rely on manual mechanical or electric sprayers to spray the fields or plants, which not only causes environmental pollution, but also leads to drug pollution. Waste of resources, and in the environment of drug droplet drift and high-temperature operation, it is easy to cause poisoning and heatstroke of workers, resulting in unnecessary casualties

The development of plant protection aircraft provides an effective and feasible solution for the control of plant diseases and insect pests in large fields, but due to the lagging technical level of plant protection aircraft and high prices, this program has not been popularized for a long time

Other related self-propelled plant protection machinery cannot adapt to crop pest control work due to the limitation of body width
