A multi-rotor unmanned aerial vehicle spraying system and spraying control method

Abstract

The invention discloses a multi-rotor UAV spraying system and a spraying control method. The control device is used to coordinately control the meteorological detection device, the flight data detection device and the spraying device to perform their respective functions, and the spraying device is adaptively adjusted according to the meteorological information and flight parameters. The spraying of drones, fully considering the influence of drone flight parameters, meteorological information, and spray droplet size on the spray radiation range, solves the problem that drone spraying in the prior art can easily lead to drift or leakage of spraying liquid, and realizes accurate spraying. Precise control of spraying.

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 agricultural yield and high quality and realizing 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 posi...

Problems solved by technology

In our 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 our country does not meet the needs of agricultural development in our country, and there is a large gap compared with foreign countries. As a result, my country's use of unmanned aerial vehicles (UAV) to spray agricultural and forestry crops 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
