Multi-rotor unmanned aerial vehicle sprinkling system and sprinkling control method

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle sprinkling system and a sprinkling control method. A control device is used for coordinately controlling a weather detection device, a flight data detection device and a sprinkling device to execute respective functions, sprinkling of the sprinkling device is adaptively adjusted according to weather information and flight parameters, the influences of the flight parameters of an unmanned aerial vehicle, the weather information and the size of sprinkling fog drops on the sprinkling radiation range are fully considered, the problem that drifting or miss sprinkling of sprinkling liquid is easily caused by unmanned aerial vehicle sprinkling in the prior art is solved, and accurate control over sprinkling is achieved.

Description

technical field [0001] The invention relates to the field of multi-rotor UAV automatic spraying, in particular to a multi-rotor UAV spraying system and a spraying control method. Background technique [0002] The world today is undergoing a technological revolution in green agriculture, organic agriculture, and precision agriculture, and more advanced digital agriculture will also be implemented. The prevention and control of agricultural diseases and insect pests is still the key content of agricultural production, and it is the basis for ensuring high-yield and high-quality agriculture and realizing the sustainable development of agricultural economy. my country's hilly and mountainous areas account for 61% of the total land area, but the hilly and mountainous areas are the main production areas of rice, rapeseed and other major crops in my country, and it is difficult to use ordinary ground equipment in the hilly and mountainous areas. Rice production is in a strategic p...

AI Technical Summary

Problems solved by technology

In my country, due to the lack of advanced unmanned aerial vehicle (UAV) spraying technology and control devices, the application level of unmanned aerial vehicle (UAV) spraying in my country does not meet the needs of agricultural development in China, and there is a large gap compared with foreign countries. As a result, my country's use of unmanned aerial vehicles (UAVs) for agricultural and forestry crop spraying has always been a blank

[0003] The UAV automatic spraying device in the prior art does not take into account the influence of UAV flight parameters and meteorological information on the radiation range of the spray liquid, and the size of the spray droplets will also affect the radiation range of the spray liquid. Effective control of liquid droplet size and spread, which can easily lead to drift or leakage of spraying liquid
