Description

Technical Field

[0001] This utility model relates to the field of agricultural monitoring technology, and in particular to a drone used for monitoring the growth of agricultural crops. Background Technology

[0002] In agricultural production, timely and accurate monitoring of crop growth is crucial for achieving scientific planting and increasing yields. Traditional crop growth monitoring methods mainly rely on manual inspections. This method not only consumes a lot of manpower and time, but also makes it difficult to achieve comprehensive and efficient monitoring of large areas of farmland. In addition, manual monitoring is highly subjective and prone to errors.

[0003] With the development of drone technology, drones are being used more and more widely in agriculture. Existing agricultural monitoring drones are typically equipped with cameras and other devices to collect crop images. However, existing agricultural monitoring drones have some shortcomings in use. On the one hand, the camera's shooting angle adjustment is not flexible enough, making it difficult to acquire crop growth information from different angles from all angles; on the other hand, in low-light environments, there is a lack of effective supplementary lighting, resulting in poor image quality and affecting the accurate assessment of crop growth.

[0004] Therefore, this utility model proposes an agricultural crop growth monitoring drone with flexible shooting angles, good supplementary lighting effect, and good autonomous flight and data transmission capabilities. Utility Model Content

[0025] As shown in the attached figure, a drone for monitoring the growth of agricultural crops includes a fuselage 1, a flight control system, a power system, a data transmission module, and a data processing module.

[0026] The power system includes a battery, a motor, and a propeller. The battery is located inside the fuselage 1 and provides power to the entire drone. The motors are symmetrically arranged on both sides of the fuselage 1, and the propellers are mounted on the output shafts of the motors. The motors drive the propellers to rotate, providing power for the drone's flight. The battery is electrically connected to the motors, flight control system, data transmission module, and data processing module to ensure the normal operation of each system.

[0027] A camera 2 is mounted on the front of the main body 1 via a base 3. The camera 2 is used to collect image information of agricultural crops. A drive motor is installed inside the base 3. The output shaft of the drive motor is connected to the camera 2. Driven by the drive motor, the camera 2 can rotate around the base 3 in both horizontal and vertical directions. The horizontal rotation angle range is 0-360°, and the vertical rotation angle range is -45° to 90°, ensuring that the camera 2 can capture crop images from different angles and heights in front of the main body 1.

[0028] A supplementary lighting assembly is installed at the bottom of the main body 1. This assembly includes a post 4, a first support arm 5, a second support arm 6, and a supplementary light 7. The post 4 is fixed to the bottom of the main body 1, serving as the mounting base for the supplementary lighting assembly. The first support arm 5 is rotatably mounted on the post 4. A second drive motor is located between the post 4 and the first support arm 5, driving the first support arm 5 to rotate around the post 4. The rotation angle range is 0-180°, allowing adjustment of the lateral position of the supplementary lighting assembly. The second support arm 6 is rotatably mounted on the other end of the first support arm 5. A third drive motor is located between the first support arm 5 and the second support arm 6, driving the second support arm 6 to rotate relative to the first support arm 5. The rotation angle range is 0-120°, allowing further adjustment of the longitudinal position and angle of the supplementary lighting assembly. A supplementary light 7 is rotatably installed at the end of the second support arm 6. A drive motor 4 is provided between the second support arm 6 and the supplementary light 7. The drive motor 4 is used to drive the supplementary light 7 to rotate relative to the second support arm 6. The rotation angle range is 0-360°, so that the supplementary light 7 can provide supplementary light to the crops from different angles.

[0029] The supplementary light 7 is an adjustable brightness LED supplementary light 7, which has advantages such as low energy consumption, high brightness, and long lifespan. The supplementary light 7 is equipped with a light sensor, which is electrically connected to the data processing module. The light sensor detects the ambient light intensity in real time and transmits the detected data to the data processing module. The data processing module controls the brightness adjustment of the supplementary light 7 based on a preset light intensity threshold and the detected actual light intensity. When the light is insufficient, the brightness of the supplementary light 7 is automatically increased; when the light is sufficient, the brightness of the supplementary light 7 is appropriately reduced or turned off to achieve the best supplementary lighting effect while saving energy.

[0030] The data transmission module includes a wireless communication unit, which can use wireless communication technologies such as 4G, 5G, and WiFi to transmit the image data collected by camera 2 to the ground control terminal in real time. Staff can view the image information of the crops and analyze and judge the growth status of the crops through the ground control terminal.

[0031] The flight control system includes a GPS positioning unit, attitude sensors, and an autopilot unit. The GPS positioning unit accurately acquires the UAV's position information, while the attitude sensors detect the UAV's flight attitude, such as pitch, roll, and heading angles. The autopilot unit controls the motor speed based on the preset flight path, GPS positioning information, and attitude information detected by the attitude sensors, enabling the UAV to autonomously take off, cruise, and land, ensuring that the UAV can fly accurately along the predetermined route and monitor crops in the designated area.

[0032] In practical use, staff preset the drone's flight path and monitoring tasks via a ground control terminal. After takeoff, the drone flies autonomously under the control of the flight control system. The GPS positioning unit locates the drone's position in real time, ensuring it flies along the preset path. Driven by motor one, camera 2 adjusts its shooting angle according to monitoring needs to capture images of the crops. When the light sensor detects insufficient ambient light, the data processing module controls the supplementary lighting components to operate. Motors two, three, and four respectively drive support arms 5 and 6, and supplementary light 7 to rotate, adjusting the position and angle of supplementary light 7 and its brightness according to light intensity to provide sufficient light for camera 2. The image data collected by camera 2 is transmitted in real time to the ground control terminal via the wireless communication unit of the data transmission module. Staff analyze the image data to understand the crop's growth status and take timely measures if pests, diseases, or poor growth are found.

[0033] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
