Plant protection unmanned aerial vehicle accurate variable operation method and device

Abstract

The embodiment of the invention provides a plant protection unmanned aerial vehicle accurate variable operation method and device. The method comprises the steps of detecting whether a current position reaches a tree age change coordinate point or not in a process that an unmanned aerial vehicle drives according to an operation track; and if the current position reaches the tree age change coordinate point, obtaining tree age information of crops corresponding to the tree age change coordinate point, and changing the pesticide application amount of the unmanned aerial vehicle according to thetree age information. When the unmanned aerial vehicle reaches the tree age change coordinate point, the tree age information of the crops corresponding to the tree age change coordinate point is obtained, and the pesticide application breadth of the unmanned aerial vehicle is changed according to the tree age information, so that the problem of insufficient pesticide application amount or excessive pesticide application amount caused by tree age difference can be avoided, and further the problems that reduction of plant protection effect is caused by the insufficient pesticide application amount and influences on the quality of agricultural products, increase of pesticide residues and environment pollution are caused by the excessive pesticide application mount are solved.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to a precise variable operation method and device for a plant protection drone. Background technique [0002] The use of plant protection drones to apply pesticides is one of the key factors affecting crop quality. It not only affects the yield of crops, but also affects the quality of agricultural products. Excessive application of pesticides during drone plant protection operations will affect the quality of agricultural products, increase pesticide residues, and pollute the environment, while too little application of pesticides will reduce plant protection effects and affect crop yields. Therefore, precise and variable drone spraying and plant protection operations are particularly important. [0003] Generally speaking, the operation of plant protection drones can be divided into manual and automatic. During manual drone plant protection operations, the drone...

AI Technical Summary

Problems solved by technology

Although this operation method has made great progress compared with manual operation, it avoids the occurrence of missed spraying and excessive spraying, but it cannot carry out variable operations according to the differences between crops, resulting in some crops still having too much or too little spraying. question
