[0022] Figure 1~2 The embodiment of the experimental soybean breeding device is shown, which includes a culture box 6 and a box body 5 for providing different light cycles for soybean breeding in a culture area. The culture box 6 is arranged in the box body 5. A stabilizing frame and a fluorescent lamp 14 are installed above the culture area, and the stabilizing frame is driven to move up and down by a telescopic bracket 4 to adjust the distance between the fluorescent lamp 14 and the soybean seedlings. The specific structure for realizing the above functions can refer to the prior art, which is roughly that the box body 5 is provided with a box door, the side wall of the box body 5 is provided with an exhaust pipe, the incubator 6 is arranged in the box body 5, and the side wall of the incubator 6 is provided with a plurality of air holes for airflow communication between the incubator 6 and the box body 5. The incubator 6 is longitudinally divided into a plurality of culture areas by a plurality of transverse plates, and a reflector 9 is provided on the inner side wall of each culture area. A stabilizing frame is provided on the top of the incubator 6 and the bottom of each transverse plate, and a plurality of daylight tubes 14 of different powers are detachably connected side by side on the stabilizing frame. Each fluorescent lamp 14 is covered with a diffuser cover, and a telescopic bracket 4 is arranged between the stabilizing frame and the inner top wall of the horizontal plate and the incubator 6. The telescopic bracket 4 is used to adjust the distance between the fluorescent lamp 14 and the soybean seedlings; a plurality of culture tanks are arranged on the incubation area of ​​the horizontal plate, and a seedling tray is arranged in the culture tank. Each seedling tray is filled with soil, and one soybean seedling or the same number of soybean seedlings are planted in each seedling tray. The nutrient solution and water in the liquid supply box 1 are connected to the seedling tray through the liquid supply pipe 2 to provide uniform moisture or nutrient solution for the soybean seedlings. A heater 7, a refrigerator, a humidifier and a fan are arranged outside the box 5, and a temperature and humidity sensor 3 is arranged inside the incubator 6. The heater 7, the refrigerator and the humidifier are connected to the box 5 through the pipeline 8 respectively, and can also be connected to the incubator 6. The temperature and humidity in the incubator 6 are controlled by the controller, the temperature and humidity sensor 3 and the heater, the refrigerator, the humidifier and the fan. The daylight tubes 14 in the same culture area are electrically connected to a timer or the controller has a built-in timer. The controller controls the timer to control the on and off of the daylight tubes 14 with different powers, so as to control the sunshine duration and the power of light in different culture areas, and realize the soybean breeding in the culture area to provide different light cycle research. No more elaboration is given here, and the main improved technologies of the present invention are mainly described as follows: The stabilizing frame includes a square frame 10 and a square frame 13. The square frame 10 is horizontally arranged for installing a number of fluorescent lamps 14 of different powers side by side. The square frame 13 is fixed below one side of the square frame 10, and the square frame 13 and the square frame 10 are perpendicular to each other, so that the lower side 12 of the square frame 13 is parallel to one side of the square frame 10. The lower side 12 of the square frame 13 serves as a reference line for the telescopic bracket 4 to adjust the distance between the fluorescent lamp 14 and the soybean seedlings.

[0023] When in use, the distance between the lower side 12 of the square frame 13 and one side of the square frame 10 is set to the required distance between the soybean seedlings and the fluorescent lamp 14 in each culture area. During the experimental soybean breeding and cultivation process, when the distance between the soybean seedlings and the fluorescent lamp 14 needs to be adjusted regularly, there is no need to enter the incubator 6 to measure the distance between the soybean seedlings and the fluorescent lamp 14. It is only necessary to drive the stabilizing frame upward through the telescopic bracket 4 to make the lower side 12 of the square frame 13 flush with the top of the soybean seedlings, that is, to visually check horizontally that the lower side 12 of the square frame 13 is flush with the top of the soybean seedlings, so as to achieve the adjustment of the equidistant between the soybean seedlings and the fluorescent lamp 14. The operation is convenient and simple, and the workload is reduced.

[0024] On the basis of the above implementation, the lower side 12 of the square frame 13 is in close contact with the inner wall of one side of the incubator 6, the inner wall of the incubator 6 faces the door of the box body 5, and the side wall of the incubator 6 is transparent. Combined with the lower side 12 of the square frame 13 being in close contact with the inner wall of the incubator 6, the water mist on the inner wall of one side of the incubator 6 can be scraped off, and it is also beneficial to visually observe the lower side 12 of the square frame 13 horizontally to determine whether the lower side 12 of the square frame 13 is flush with the top of the soybean seedlings, thereby improving the reference effect and adjustment efficiency.

[0025] On the basis of the above implementation method, the vertical edges 11 on both sides of the square frame 13 are frame edges with adjustable lengths, so that the distance between the lower edge 12 of the square frame 13 and one side of the square frame 10 is adjustable, meeting the different distance requirements between the soybean seedlings and the fluorescent lamp tube 14 in different experiments and improving applicability.

[0026] On the basis of the above implementation, it also includes an integrated infrared transmitter and receiver 16 and a swing motor. The integrated infrared transmitter and receiver 16 is arranged on the lower side 12 of the square frame 13 through the swing motor and can swing horizontally, so that the infrared light emitted by the integrated infrared transmitter and receiver 16 is parallel to the square frame 13, which is used to scan and detect the top of the soybean seedlings; the telescopic bracket 4 is an electric telescopic bracket (for example, the electric telescopic bracket is an electric telescopic rod, one end of the electric telescopic rod is vertically arranged at the top of the incubator 6 or the bottom of each horizontal board, and the other end is vertically arranged on the square frame 10 to realize the electric control of the stable frame to drive the fluorescent lamp 14 to move up and down, and the swing motor can be a micro swing motor, which is small in size and low in power consumption, and is very suitable for application scenarios of driving small components), and the integrated infrared transmitter and receiver 16, the swing motor, the electric telescopic bracket and the fluorescent lamp 14 are electrically connected to the controller respectively. When the controller detects through the timer that the distance between the soybean seedlings and the fluorescent lamp 14 needs to be adjusted, the controller controls the swing motor to drive the integrated infrared transmitter and receiver 16 to swing left and right in the horizontal direction and controls the integrated infrared transmitter and receiver 16 to transmit and receive infrared signals to detect the top of the soybean seedlings. If a signal of a top blocking of the soybean seedlings is detected, the electric telescopic bracket is controlled to gradually shorten and the fluorescent lamp 14 is moved upward until the signal of a top blocking of the soybean seedlings is no longer detected, and the electric telescopic bracket is suspended from shortening. In this adjustment process, the fluorescent lamp 14 can also be controlled to be turned off first, and then the top of the soybean seedlings is scanned for detection, which helps to improve the detection effect.

[0027] In the above technical solution, the soybean breeding device used in this experiment mainly includes a square frame 13, an integrated infrared transmitter and receiver 16, a swing motor, an electric telescopic bracket, a sunlight lamp 14, a controller and other components.

[0028] The integrated infrared transmitter and receiver 16 is arranged on the lower side 12 of the square frame 13 through a swing motor, is located in the middle of the lower side 12 of the square frame 13, and can swing horizontally. The integrated infrared transmitter and receiver 16 is used to scan and detect the top of the soybean seedling. Its working principle is to transmit infrared signals and receive reflected signals, and determine whether there is the top of the soybean seedling at the horizontal position of the scan by calculating the time difference or phase difference of the signal.

[0029] The swing motor is connected to the integrated infrared transmitter and receiver 16, and is responsible for driving it to swing left and right in the horizontal direction. Driven by the swing motor, the integrated infrared transmitter and receiver 16 can fully scan the soybean seedlings on the adjusted horizontal plane to ensure that the top of each soybean seedling in the cultivation area is detected without omission.

[0030] The electric telescopic bracket is used to support the stabilizing frame and the fluorescent lamp 14, and can be telescopically adjusted according to the instructions of the controller. By adjusting the electric telescopic bracket, the distance between the fluorescent lamp 14 and the soybean seedlings can be changed. The electric telescopic bracket has the characteristics of high precision, high stability and high reliability, and can ensure the precise adjustment of the position of the fluorescent lamp 14.

[0031] The sunlight lamp 14 provides the required illumination conditions for the soybean seedlings. Its illumination intensity, spectrum and other parameters can be set or selected according to the experimental requirements.

[0032] As the core component of the device control, the controller is responsible for receiving the signal of the integrated infrared transmitter and receiver 16, and accurately controlling the swing motor, the electric telescopic bracket and the fluorescent lamp 14 according to the preset program and parameters. The controller also has a timer function, which can monitor the growth time of the soybean seedlings and issue instructions when the distance between the soybean seedlings and the fluorescent lamp 14 needs to be adjusted.

[0033] The experimental soybean breeding device of the present invention also discloses another implementation method, which integrates image processing and machine learning technology, can accurately count the number and area of ​​soybean leaves, and provides a powerful tool for soybean breeding research.

[0034] The soybean breeding device used in this experiment was upgraded on the original basis, and two core components, a camera 15 and a control panel, were added, further improving the intelligence level of the device.

[0035] The camera 15 is installed under the square frame 10 of the stabilizing frame, and is in a moderate position to clearly capture the image of the soybean leaves. The camera 15 is electrically connected to the controller, and can transmit the captured image information to the controller for processing in real time according to a set cycle. Through the camera 15, we can obtain the growth of soybean leaves, which provides a basis for subsequent data analysis and processing.

[0036] The control panel serves as a bridge for the user to interact with the device and is electrically connected to the controller. It can not only display the statistical results of the blade images captured by the camera 15 (such as the number and area of ​​blades), but also record and store these data for the convenience of subsequent analysis and comparison by the user. At the same time, the control panel also supports receiving user instructions and parameter settings, such as setting the time interval for blade statistics, adjusting the algorithm parameters of image processing, etc., which provides great convenience for users.

[0037] The specific implementation process of counting the number of leaves and the area of ​​leaves: Image capture and processing: When the controller detects the time point when the number and area of ​​leaves need to be counted through the timer, or the user issues a statistical instruction through the control panel, the controller will control the daylight tubes 14 in the culture area to adjust their power to the same, reducing the impact of different light on image capture to ensure the consistency of image capture. Subsequently, the camera 15 begins to capture the image of the soybean leaves and transmits the image information to the controller for processing. After the image is captured, the controller will control the daylight tubes 14 to return to their previous power to ensure the experimental environment requirements of soybeans.

[0038] Leaf detection and number counting: The controller uses deep learning algorithms (such as the YOLO algorithm) to train a leaf detection model to identify and process the captured images (the captured images can be preprocessed first, including denoising and contrast enhancement to improve image quality). The YOLO algorithm is efficient and accurate and can quickly identify the location and number of leaves. Through this algorithm, we can obtain the precise location and number information of the leaves in each image.

[0039] Leaf segmentation and area calculation: After obtaining the position and number information of the leaves, the controller uses an image segmentation algorithm (such as the U-Net algorithm) to accurately segment the identified leaves. The U-Net algorithm is an image segmentation method based on a convolutional neural network, which has excellent segmentation performance and robustness. Through this algorithm, we can accurately segment the leaves from the image, providing a basis for subsequent area calculations. Next, the controller uses a pixel counting method to calculate the leaf area. The specific method is to scan line by line to determine and count the number of pixels within the leaf boundary, and then multiply by the area of ​​each pixel to obtain the exact area of ​​the leaf.

[0040] The specific implementation process of user interaction and data storage: User interaction: Users can interact with the device through the control panel, such as setting the interval for blade statistics, viewing statistical results, exporting data, etc. The control panel provides a friendly user interface and rich functional options, allowing users to easily operate and manage.

[0041] Data storage: The controller will store the blade quantity and area information obtained each time in the built-in data storage unit. Users can view historical data at any time through the control panel for data analysis and comparison. At the same time, users can also store data in external storage devices (such as USB flash drives, hard drives, etc.) for more in-depth data mining and application.

[0042] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. They can be applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
