Real-time target spraying control system and spraying method of greenhouse sprayer

Abstract

The invention belongs to the technical field of automatic control of agricultural machinery equipment, and relates to a real-time target spraying control system for a greenhouse sprayer and a spraying method. The target spraying control system comprises a laser sensor, a single-chip microcomputer controller, an obstacle avoidance sensor, a monitor display screen, a wireless remote controller, a motor driver, a motor, a pesticide mixing box, a filter, a diaphragm pump, a flow sensor, a solenoid valve, an overflow valve and a plurality of spray nozzles. The spraying method adopts continuous dynamic sampling for three times according to different driving speeds, and a target is judged in real time, so frequent opening and closing of the solenoid valve due to excessively large sampling frequency and error spraying due to large gaps among branches and leaves of a canopy layer or empty cavities in the canopy layer of a fruit tree can be effectively avoided. Compared with the prior art, the target spraying control system has the advantages of simple installation and debugging, high target precision, strong operability, good spraying effect, etc.

Description

technical field [0001] The invention belongs to the technical field of automatic control of agricultural machinery equipment, and relates to a real-time target spraying control system and spraying method of a greenhouse sprayer. Background technique [0002] The traditional method of spraying pesticides is continuous spraying. Due to the discontinuous planting of greenhouse crops, many pesticides are sprayed in the gaps between fruit trees and are not deposited on the crops, which affects the control effect of crops. Converting continuous pesticide application to intermittent automatic target pesticide application is an effective solution to solve the current low pesticide utilization rate and large environmental impact. Automatic control realizes targeted application, and finally achieves the purpose of spraying only on specific targets. [0003] At present, the greenhouse target detection technology can be divided into ultrasonic sensor-based, image processing-based and i...

Problems solved by technology

However, due to the beam angle of the ultrasonic sensor, the accuracy of target recognition is low; the image processing time is long, and the response delay is high; the infrared sensor is greatly affected by the environment, and the detection distance is short

[0004] Publication No. CN103548802A provides a self-propelled orchard automatic target sprayer and its spraying method. The sampling frequency is fixed. When the driving speed is too high, the target will be inaccurate, and the complete target is not given at the same time. Spray Control Procedure
