Intelligent pesticide applying system and control method of plant protection unmanned aerial vehicle

Abstract

The invention relates to an intelligent pesticide applying system and a control method of a plant protection unmanned aerial vehicle. The system is provided with a meteorological station used for measuring environment parameters and sending collected data to a ground station. The ground station sends the environment parameters, pesticide applying control parameters and control commands to an onboard pesticide applying controller on the plant protection unmanned aerial vehicle through a wireless data transmission module. Meanwhile, a flight controller measures real-time geographic information parameters and flight parameters of the plant protection unmanned aerial vehicle and sends collected data to the onboard pesticide applying controller in real time. The onboard pesticide applying controller conducts autonomous programmed decisions by combining the flight parameters, the environment parameters, the pesticide applying control parameters and the control commands, a miniature diaphragm pump and two centrifugal atomization disc sprayers are independently controlled, and therefore the pesticide liquid flow, the mist drop diameters and spraying width parameters of the plant protection unmanned aerial vehicle are intelligently controlled. By means of the intelligent pesticide applying system and the control method, it is guaranteed that pesticide in an operation area is quantitative and evenly sprayed in a fully covering mode, the phenomena of repeated spraying and miss-spraying of the pesticide are avoided, the pesticide applying quality is improved, and effective prevention and treatment of farmland pest and disease damage are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of agricultural aviation plant protection, and in particular relates to an intelligent pesticide application system and control method of a plant protection drone. Background technique [0002] Chemical control is the fastest and most effective way to control pests and diseases in agriculture. Agricultural aviation is an important part of modern agriculture and one of the important symbols reflecting the level of agricultural modernization. Agricultural plant protection drones have the characteristics of strong mobility, high operating efficiency, low cost, and strong environmental adaptability, and their applications in domestic crop pesticide application, fertilization, pollination, and farmland monitoring are gradually emerging. The application of plant protection UAV pesticide application technology in the field of crop pest control has just started, and the UAV pesticide application system and control ...

AI Technical Summary

Problems solved by technology

At present, the existing plant protection drones on the market are mainly single-rotor oil-powered plant protection drones and multi-rotor electric plant protection drones. Variations in parameters and variable application of pesticides make it difficult to achieve quantitative and uniform spraying of pesticides in the entire operation area. The phenomenon of "heavy spraying" and "missing spraying" is common, and the effect of pest control is not ideal.
