Precise broadcast sowing system and method based on agricultural small unmanned aerial vehicle

Abstract

The invention discloses a precise broadcast sowing system and method based on an agricultural small unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles. The systemcomprises an unmanned aerial vehicle, a ground control station and a ground command center, wherein the ground command center is connected with the ground control station, the ground control station is in wireless communication connection with the unmanned aerial vehicle, the ground command center comprises a man-machine interaction terminal, a data analysis and processing module is arranged in the human-machine interaction terminal, a flight control system is arranged in the unmanned aerial vehicle body, the ground control station is in wireless communication connection with the flight control system, the unmanned aerial vehicle is provided with a GPS positioning module and an infrared device, and the GPS positioning module and the infrared device are both connected with the flight control system. The automation degree of the system provided by the invention is high, needed technicians are few, and the technicians only need to input relevant information of a farmland into the human-machine interaction terminal. The unmanned aerial vehicle can seed automatically, so that a lot of manpower and material resources are saved; and precise seeding of the farmland is more beneficial for the increase of the yield of crops.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a seed precision sowing system and method based on a small agricultural unmanned aerial vehicle. Background technique [0002] With the continuous development and maturity of UAV technology, UAVs have been widely used in military, agricultural and other fields. At present, most agricultural sowing is artificial sowing or sowing by seeding machines. The speed of artificial sowing is slow and people are not like machines. , cannot continue to work in a full state, and it is more difficult to achieve precision seeding than machines. There are serious problems with the indentation of tires on both sides of the seeder, which will lead to the problem of water accumulation, which will lead to serious problems of uneven rice seed development. [0003] Therefore, people have begun to utilize unmanned aerial vehicles that can fly stably at low altitudes to achieve sowing. ...

Problems solved by technology

UAV sowing has also been realized in the existing technology, but the common problem is that the suitable row spacing for sowing is not well controlled, and precision sowing cannot be done, which affects the yield

[0004] The invention patent with the Chinese publication number CN104255137A discloses a precision seeding operation system and method based on an unmanned aerial vehicle platform, the system includes an unmanned aerial vehicle (1) and a seeding device (2) fixed on the unmanned aerial vehicle; The sowing device (2) comprises a seed box (15), a fixed seat (16), a wind force seeding device, a quantitative sowing roller (18), a roller blade (19) and a servo motor (22); the servo motor is driven by a battery; The seed scattering device is a separate fan (17) or an air supply duct made up of a fan and a sleeve; the seed box (15) is fixed on the top of the fixed seat (16); the servo motor (22) is installed on the fixed seat ; Though this invention adopts the quantitative seeding roller (18) controlled by the servo motor to realize precision sowing, it cannot comprehensively consider information such as seed type, topography, salinity, pH value, etc., and draws the suitable row spacing of sowing, which cannot realize precise seeding. Sowing, therefore, affects yield
