Description

Technical Field

[0001] This invention relates to a rotating agricultural seedling raising device, specifically a rotating agricultural seedling raising device and its control method. Background Technology

[0002] In the field of agricultural seedling cultivation, traditional seedling devices have long faced problems such as insufficient light energy utilization, crude control methods, and insufficient reliability. Traditional seedling devices are mostly fixed structures that cannot be adjusted according to changes in the sun's position. As a result, the plants on the seedling racks can only receive light from a limited angle, resulting in short and unevenly distributed light throughout the day and low light energy utilization efficiency. This directly leads to insufficient photosynthesis in plants, slow growth, and extended seedling cycles, often several days or even longer than ideal.

[0003] In terms of control methods, traditional devices lack intelligent adjustment mechanisms. Most employ simple manual control or fixed program control, lacking the ability to dynamically adjust based on real-time solar position data. They lack dual-data source calibration mechanisms, such as those combining astronomical data from 4G networks with sensor measurements, and cannot achieve precise positioning control, resulting in significant positioning accuracy errors, often exceeding ±10°. Furthermore, traditional control methods are mostly open-loop control, unable to adjust rotation speed in real-time according to the sun's trajectory. During periods of rapid solar position change, such as sunrise and sunset, they cannot respond promptly, while at midday when the sun's position is relatively stable, unnecessary energy consumption may occur, leading to slow overall response speed and high energy consumption.

[0004] In terms of handling abnormal situations, traditional seedling cultivation devices have very limited capabilities. When encountering problems such as network outages, sensor malfunctions, or power supply anomalies, they often lack effective response strategies. For example, if the network is interrupted and external data cannot be obtained, the device may stop working directly; if a sensor malfunctions, there is no alternative data source to support the device's operation; if there is a power supply problem, power cannot be allocated reasonably to ensure the operation of core components. This makes the device extremely unstable under extreme conditions, easily affecting the seedling cultivation process and causing economic losses.

[0005] Furthermore, traditional seedling raising equipment has weak remote monitoring capabilities, relying mostly on manual inspections to understand its operational status. Managers struggle to grasp the real-time situation of the equipment. Once a malfunction occurs, it often takes a considerable amount of time to detect and resolve, with response times often measured in hours. This not only increases labor costs but also negatively impacts seedling raising results due to delayed troubleshooting. These numerous problems with traditional equipment hinder the improvement of efficiency and quality in agricultural seedling raising, making it difficult to meet the demands of modern agricultural seedling raising for precision, intelligence, and high efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a rotating agricultural seedling raising device and a control method.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is a rotating agricultural seedling raising device and a control method: a rotating agricultural seedling raising device includes a bottom support plate, a support column, an upper support plate, an electric rotating platform, a multi-layer agricultural seedling raising frame, lockable walking wheels, a storage battery, a controller, a 4G module and a solar position sensor.

[0008] The bottom support plate has a square projection when viewed from above, and there are four support columns, which are respectively located at the four corners of the bottom support plate.

[0009] The upper support plate is located on the upper part of the support column, the electric rotary platform is located on the upper part of the upper support plate, and the multi-layer agricultural seedling frame is located on the electric rotary platform.

[0010] The lockable wheels are located at the corners of the bottom support plate; the battery and controller are located on the upper side of the bottom support plate.

[0011] The 4G module is fixed to the controller;

[0012] The controller is electrically connected to the battery, the electric slewing platform, the 4G module, and the solar position sensor. The 4G module is used to connect the device to the Internet, and the solar position sensor is used to detect the position of the sun.

[0013] As an improvement, the 4G module can access the mobile network by inserting a valid SIM card.

[0014] As an improvement, the solar position sensor is a photoelectric sensor or a solar tracking sensor.

[0015] As an improvement, the electric rotary platform is equipped with an angle sensor, which is electrically connected to the controller and is used to detect the rotation angle of the electric rotary platform.

[0016] A control method for a rotating agricultural seedling raising device, S1. Internet connection: The controller accesses the Internet via a 4G module to obtain the latitude and longitude of the device's location, real-time time, and astronomical data related to the sun's position;

[0017] S2. Solar Azimuth Analysis: The controller detects the real-time position of the sun through the solar position sensor, and combines it with the astronomical data obtained in step S1 to analyze the solar azimuth angle and altitude angle. When there is a deviation between the two, the astronomical data is calibrated based on the data detected by the solar position sensor to obtain accurate solar azimuth information.

[0018] S3. Electric Rotary Platform Control: Based on the calibrated solar azimuth angle information and the existing orientation angle of the multi-layer agricultural seedling frame, the controller uses a PID control algorithm to calculate the required rotation angle of the electric rotary platform and sends a control command containing the rotation direction and rotation angle to the electric rotary platform. The electric rotary platform executes the command to rotate, and at the same time, it feeds back the rotation angle to the controller through the built-in angle sensor. The controller compares the feedback angle with the target angle. If there is a deviation, it issues an adjustment command until the multi-layer agricultural seedling frame is accurately facing the sun.

[0019] As an improvement, step S5 also includes an exception handling step:

[0020] When the 4G network connection is interrupted, the controller automatically switches to a working mode that relies solely on the sun position sensor to detect the sun's position and continuously attempts to reconnect to the network. Once the network is restored, it automatically switches back to normal working mode.

[0021] When the solar position sensor malfunctions, the controller issues a fault warning signal and relies solely on solar position data obtained from the Internet for control.

[0022] When the battery power is too low or a power supply failure occurs, the controller starts a low-power mode to prioritize the power supply to the core components and issues a power failure warning.

[0023] As an improvement, in step S3, the PID control algorithm can adjust the rotation angle of the electric rotary platform in real time according to the change of the sun's position.

[0024] The advantages of this invention compared to existing technologies are: improved light energy utilization efficiency.

[0025] By monitoring the sun's position in real time using a solar position sensor and calibrating with astronomical data, the multi-layered agricultural seedling rack can precisely follow the sun's rotation. This dynamic tracking mechanism ensures that the plants on the rack receive ample sunlight throughout the day, significantly improving photosynthetic efficiency. Compared to traditional fixed seedling devices, it can increase light utilization by more than 30% and effectively shorten the seedling cycle by 57 days.

[0026] Intelligent control and data fusion: Dual data source calibration: Combining astronomical data acquired through the 4G network with actual sensor data forms a complementary verification mechanism. When weather changes cause fluctuations in sensor data, astronomical data provides a stable reference; when the network is interrupted, the sensor operates independently to ensure system operation, with an overall positioning accuracy error of less than ±2°.

[0027] PID Adaptive Adjustment: The PID control algorithm dynamically adjusts the rotation speed of the slewing platform according to the sun's movement trajectory. It makes slow and fine adjustments during sunrise and sunset, and fast tracking during midday. The response speed is 40% faster than traditional open-loop control, and energy consumption is reduced by 25%.

[0028] Anomaly Response and Enhanced Reliability: Multi-level Fault Handling: Separate response strategies are designed for network outages, sensor failures, and power failures to ensure the system maintains basic functionality even under extreme conditions. For example, the low-power mode can maintain the core control unit's operation for more than 8 hours after a power outage, ensuring a stable seedling environment.

[0029] Remote monitoring and early warning: The 4G module supports remote operation and maintenance. Managers can view the device status and receive fault alarms in real time through a mobile APP, reducing the response time from hours to minutes in traditional manual inspections.

[0053] As an improvement, in step S3, the PID control algorithm can adjust the rotation angle of the electric rotary platform 4 in real time according to the change of the sun's position.

[0054] Structure of a rotating agricultural seedling raising device:

[0055] The rotating agricultural seedling raising device mainly consists of a bottom support plate 1, a support column 2, an upper support plate 3, an electric rotating platform 4, a multi-layer agricultural seedling raising frame 5, lockable walking wheels 6, a storage battery 7, a controller 8, a 4G module 9, and a solar position sensor 10.

[0056] The bottom support plate 1 has a square projection when viewed from above, which provides good stability to the bottom of the device. Four support columns 2 are respectively set at the four corners of the bottom support plate 1, providing a stable support structure for the entire device. The upper support plate 3 is installed on top of the support columns 2, forming a stable platform.

[0057] An electric rotating platform 4 is mounted on top of the upper support plate 3, and the multi-layer agricultural seedling frame 5 is installed on the electric rotating platform 4. The function of the electric rotating platform 4 is to drive the multi-layer agricultural seedling frame 5 to rotate, thereby achieving sun tracking. Lockable wheels 6 are located at the corners of the bottom support plate 1 for easy movement and fixation of the device. When the device needs to be moved, the wheels are unlocked; when the device reaches the designated position, the wheels are locked to ensure the stability of the device.

[0058] The battery 7 and controller 8 are mounted on the upper side of the bottom support plate 1. The battery 7 provides power to the entire device, while the controller 8 is the core control component, responsible for coordinating and controlling all parts. The 4G module 9 is fixed to the controller 8 and is used to enable the device to connect to the Internet. The solar position sensor 10 is used to detect the position of the sun, providing a basis for the rotation of the device.

[0059] Control method of rotary agricultural seedling raising device:

[0060] The control method of the rotating agricultural seedling raising device mainly includes steps such as Internet connection, solar orientation analysis and electric rotary platform control.

[0061] During the internet connection step, controller 8 connects to the internet via 4G module 9 to obtain the latitude and longitude of the device's location, real-time time, and astronomical data related to the sun's position. This data provides the foundation for subsequent solar position analysis.

[0062] In the solar azimuth analysis step, the controller 8 detects the real-time position of the sun through the solar position sensor 10, and analyzes the sun's azimuth and altitude angles by combining this with astronomical data obtained from the internet. When there is a discrepancy between the two, the astronomical data is calibrated based on the data detected by the solar position sensor 10, thereby obtaining accurate solar azimuth information.

[0063] In the control steps of the electric rotary platform 4, the controller 8 calculates the required rotation angle of the electric rotary platform 4 using a PID control algorithm based on the calibrated solar azimuth angle information and the existing orientation angle of the multi-layer agricultural seedling frame 5, and sends a control command containing the rotation direction and rotation angle to the electric rotary platform 4. The electric rotary platform 4 executes the command and rotates, while simultaneously feeding back the rotation angle to the controller 8 via a built-in angle sensor. The controller 8 compares the feedback angle with the target angle; if there is a deviation, it issues an adjustment command until the multi-layer agricultural seedling frame 5 accurately faces the sun.

[0064] Exception handling:

[0065] Various abnormal situations may occur during the operation of a rotary agricultural seedling raising device. To ensure the stable operation of the device, the control method also includes abnormal handling procedures.

[0066] When the 4G network connection is interrupted, the controller 8 will automatically switch to a working mode that relies solely on the solar position sensor 10 to detect the sun's position and will continuously attempt to reconnect to the network. Once the network is restored, the device will automatically switch back to normal working mode.

[0067] When the solar position sensor 10 malfunctions, the controller 8 will issue a fault warning signal and will rely solely on solar azimuth data obtained from the Internet for control.

[0068] When the battery 7 has low power or a power supply failure occurs, the controller 8 will start a low-power mode to prioritize the power supply to the core components and issue a power failure warning.

[0069] Through the above structural design and control methods, the rotating agricultural seedling raising device can automatically track the sun, making full use of sunlight resources and improving seedling raising efficiency and quality. Meanwhile, the inclusion of abnormal handling procedures ensures stable operation of the device under various conditions.

[0070] Improve light energy utilization efficiency:

[0071] By monitoring the sun's position in real time using a solar position sensor and calibrating with astronomical data, the multi-layered agricultural seedling rack can precisely follow the sun's rotation. This dynamic tracking mechanism ensures that the plants on the rack receive ample sunlight throughout the day, significantly improving photosynthetic efficiency. Compared to traditional fixed seedling devices, it can increase light utilization by more than 30% and effectively shorten the seedling cycle by 57 days.

[0072] Intelligent control and data fusion:

[0073] Dual data source calibration: Combining astronomical data acquired through the 4G network with actual sensor measurements forms a complementary verification mechanism. When weather changes cause fluctuations in sensor data, astronomical data provides a stable reference; when the network is interrupted, the sensor operates independently to ensure system operation, with an overall positioning accuracy error of less than ±2°.

[0074] PID Adaptive Adjustment: The PID control algorithm dynamically adjusts the rotation speed of the slewing platform according to the sun's movement trajectory. It makes slow and fine adjustments during sunrise and sunset, and fast tracking during midday. The response speed is 40% faster than traditional open-loop control, and energy consumption is reduced by 25%.

[0075] Anomaly response and reliability enhancement:

[0076] Multi-level fault handling: Separate strategies are designed for network outages, sensor failures, and power failures to ensure the system can maintain basic functions even under extreme conditions. For example, the low-power mode can maintain the core control unit's operation for more than 8 hours after a power outage, ensuring a stable seedling environment.

[0077] Remote monitoring and early warning: The 4G module supports remote operation and maintenance. Managers can view the device status and receive fault alarms in real time through a mobile APP, reducing the response time from hours to minutes in traditional manual inspections.

[0078] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
