[0022] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0023] In the present invention, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0024] See also Figure 1-2 The agricultural drone space management system shown includes:

[0025] Camera, used to globally scan the farmland area and collect global image information of the farmland;

[0026] A remote controller is wirelessly connected to the camera and the spraying device installed on the drone;

[0027] A processor, disposed in the remote controller, is used to parameterize the global image information of the farmland, including planning the ridges as boundary lines, and planning the areas enclosed by the boundary lines as spraying areas and numbering them;

[0028] The processor is also used to plan the path for each spraying area corresponding to the number, and connect the beginning and end paths of two consecutive spraying areas.

[0029] Through the implementation of the above technical solutions, the drone can be flown and the camera on the drone can be used to collect global images of the farmland, and the global images of the farmland can be stored for direct use next time. Then, the spraying path can be planned based on the global image. When the drone carries pesticides for spraying, it can automatically spray according to the planned path. The drone can be remotely controlled by the remote controller and the collected image information can be received, so as to realize global control of pesticide spraying in farmland and improve spraying efficiency.

[0030] In this embodiment, in order to further provide a spraying device, the spraying device includes two symmetrically arranged liquid storage chambers 1; a spraying head is arranged at the bottom of the two liquid storage chambers 1. The two liquid storage chambers 1 are filled with different types of pesticides, which are transported to the spraying head position by pumping and pressurizing, and sprayed downward, and the spraying path follows the planned path, for example, walking in a serpentine path in the spraying area.

[0031] In this embodiment, the spray head includes a rotating tube 3, a transverse tube 4 and a vertical spray head 5; the rotating tube 3 is sleeved with a first gear 7, and a motor 2 is arranged between the two first gears 7 at the bottom of the two liquid storage chambers 1; the motor 2 is sleeved with a second gear 6 that meshes with the first gears 7 on both sides. Through such a setting, the two transverse tubes 4 are always in a parallel and unidirectional extension state, and the motor 2 drives the rotating tube 3 to rotate, which can drive one of the vertical spray heads 5 that needs to be sprayed to move to the middle position of the two liquid storage chambers 1, which can make the spraying of pesticides more accurate on the one hand, and on the other hand, it can better overcome the reaction force on the drone caused by the spraying of pesticides, making the drone flight more stable.

[0032] In this embodiment, a touch display panel is provided on the remote controller; the processor is used to simulate and display the parameterized global image information of the farmland on the touch display panel, and can interact with the user; the interactive options include: selecting a spraying area with a corresponding number, and selecting the corresponding spraying area to execute no spraying or a corresponding spraying head. Through such a setting, a position where a drone takes off is selected as the initial position, and in addition, it is selected whether the spraying area is sprayed, and which spraying head is used for spraying the spraying area. When the save is selected, the path is replanned and spraying is performed according to the new path.

[0033] In this embodiment, the agricultural drone space management system also includes a visual system or a radar system; when the drone is spraying pesticides, the visual system or the radar system senses the height of the crops and performs adaptive adjustment of the drone's flight altitude. Through such a setting, the drone can adaptively change in spatial altitude to improve the effect of spraying pesticides on crops at different altitudes.

[0034] In this embodiment, the processor is also used to control the drone to return to the base station to replace the battery or replenish the dosage when the drone is low on power or the pesticide liquid level is lower than a set value. Through such a setting, when the drone is low on power or the pesticide liquid is insufficient, it can automatically return to replace the battery or replenish the dosage.

[0035] In this embodiment, in order to further provide a camera type, the camera is a binocular camera. By using the binocular camera, the accuracy of image acquisition is increased and the path planning accuracy is improved.
