Automatic liquid level detection and replenishment system for plant protection unmanned aerial vehicle medicine tank

Abstract

The invention discloses an automatic liquid level detection and replenishment system for a plant protection unmanned aerial vehicle medicine tank. The system comprises a medicine tank liquid level detection subsystem, an unmanned aerial vehicle flight control subsystem and a medicine mixing subsystem, wherein the medicine tank liquid level detection subsystem comprises an unmanned aerial vehicle medicine tank, a liquid level detection module and a data transmission module I; the unmanned aerial vehicle flight control subsystem comprises a unmanned aerial vehicle flight control module and a remote control display module; and the medicine mixing subsystem comprises a medicine mixing box and a data transmission module II. The invention further discloses a plant protection unmanned aerial vehicle liquid medicine supply method, which includes judging and sending alarm information by detecting the liquid level height of the unmanned aerial vehicle medicine box; starting, by the medicine mixing box, mixing medicine after the alarm information is received; acquiring, by the unmanned aerial vehicle, position information of the medicine mixing box and planing a return route; after the supplyis completed, flying back to the starting point of the previous return to continue plant protection operations. By establishing a trinity system of detection, medicine mixing and supply, the system realizes communication between the medicine mixing box and a plurality of unmanned aerial vehicles, and timely medicine mixing and rapid supply are realized.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to an automatic detection and replenishment system and a replenishment method for the liquid level of a medicine box of a plant protection drone. Background technique [0002] With the development of precision agricultural aviation, plant protection drones are more and more widely used in agricultural and forestry production. The use of plant protection drones for flying defense operations can avoid pesticides from harming human health and reduce the burden on operators; it can greatly improve the utilization rate of pesticides and reduce the use of chemical fertilizers and pesticides; it can improve the efficiency of agricultural production and improve the level of agricultural modernization in my country. [0003] At present, the plant protection UAV has the problem of relatively small load and short battery life. At the same time, when most UAVs are performing ...

AI Technical Summary

Problems solved by technology

[0004] Some existing drug mixing devices only have the function of mixing drugs, do not have the function of data transmission, and cannot be associated with the liquid level information of the drone’s medicine box on the job site to form a local area network, which cannot achieve timely mixing of drugs and rapid replenishment
