Variable spraying machine based on image acquisition

Abstract

The invention discloses a variable spraying machine based on image acquisition; the variable spraying machine comprises a sprayer, an image acquisition system, a spray amount deciding system, a spray amount control system, and a spray state monitoring system; the sprayer is used for completing a spraying process; the image acquisition system is used for collecting farmland images and sending the images to the spray amount deciding system for processing; the spray amount deciding system processes the collected farmland images so as to obtain spray amount deciding information; the spray amount control system controls nozzles of the sprayer to open and close according to the spray amount deciding information sent by the spray amount deciding system, thus realizing variable spraying; the spray state monitoring system can detect a work state signal of the variable spraying machine in real time, and sends the signal to the spray amount control system. The spraying machine can realize spraying according to needs so as to improve pesticide utilization rate, can realize nozzle blocking alarming, can automatically display performance indexes like medicine chest amount, nozzle spray amount and spraying pressure, thus comprehensively monitoring the spray state.

Description

technical field [0001] The invention belongs to the technical field of plant protection machinery, and in particular relates to a variable-variable spraying machine based on image collection, which is suitable for precision agriculture and protective tillage. Background technique [0002] At present, ordinary sprayers generally adopt the extensive spraying method when working in the field. Regardless of the distribution characteristics of weeds and crops in the spatial area, a unified herbicide application plan is formulated regardless of the size of the work plot, and uniform application is adopted. Only 20% to 30% of the herbicides sprayed by plant protection machinery (50% in developed countries) have the effect of weeding, and most of the herbicides are lost to the surrounding environment, which increases the production cost of agricultural products and affects the ecology. The environment has caused harm and seriously restricted the sustainable development of agricultur...
