Description
Technical Field
[0001] This invention belongs to the field of agricultural seedling raising technology, specifically relating to a supplementary lighting device for a smart factory for vertical rice seedling raising. Background Technology
[0002] The high efficiency and intelligentization of agricultural production are the core directions of modern agricultural development. Currently, with the migration of rural labor to cities and the increasing trend of population aging, the demand for automation and intelligent technologies in agricultural production is becoming more and more urgent. Among them, the vertical rice seedling raising factory, as a key carrier for the large-scale and standardized rice seedling raising, has seen its technological upgrading become an important breakthrough in improving seedling quality and ensuring the effectiveness of mechanized transplanting.
[0003] In vertical rice seedling factories, light is a core environmental factor affecting seedling photosynthesis and morphogenesis, directly determining seedling growth rate, stress resistance, and final quality. Because natural light cannot evenly cover multiple layers of seedling racks in a factory-style vertical cultivation model, artificial lighting has become a necessary means to ensure healthy seedling growth.
[0004] However, existing supplemental lighting equipment has many limitations. Traditional supplemental lighting equipment uses fixed flat-panel supplemental lighting panels. The fixed position and fixed range of light radiation of fixed flat-panel supplemental lighting panels will result in the seedlings receiving light from a single angle and uneven light distribution, which will cause the seedlings to grow unevenly and thus result in poor seedling growth quality. Summary of the Invention
[0005] In view of this, the present invention provides a supplementary lighting device for a smart factory for vertical rice seedling raising, in order to solve the existing technical problems.

The supplemental lighting assembly includes a mounting panel, a main lamp tube, and multiple auxiliary lamp tubes. The main lamp tube and auxiliary lamp tubes are located on the mounting panel and are respectively signal-connected to a dimming component. The length direction of the main lamp tube is aligned with the length direction of the mounting panel. The mounting panel is connected to the support frame. The multiple auxiliary lamp tubes are evenly distributed on both sides of the main lamp tube in a cantilevered structure along its length, with an angle between the auxiliary lamp tubes and the main lamp tube. The device also includes: A dimming component, signal-connected to the supplementary lighting component, is used to control the light intensity of the supplementary lighting component; A driving device, connected to the bracket, is used to drive the bracket to rotate and change the illumination radiation range of the supplementary lighting component; Monitoring components are used to acquire images of light intensity and seedlings; The controller is connected to the dimming component, the monitoring component, and the driving device via signals. The controller is used to drive the driving device according to a preset time sequence. The controller is also used to synchronously receive images of light intensity and seedlings sent by the monitoring component, determine the growth stage of the seedlings based on the images of the seedlings, record the growth stage and light intensity data of the seedlings according to the time sequence, compare them with preset parameters to determine the supplementary lighting difference, and issue a supplementary lighting control command to the dimming component based on the supplementary lighting difference.
[0007] Furthermore, the mounting panel includes a first plate, a second plate, and a third plate arranged sequentially. The first plate and the third plate have the same structure and are symmetrically arranged relative to the central plane of the second plate. The first plate and the third plate are respectively fixedly connected to one opposite end of the second plate, and the first plate and the third plate form an obtuse angle. The second plate is fixedly connected to one end of the bracket. The main lamp tube is set on the second plate, and the end of the main lamp tube away from the driving device is the positive direction of the main lamp tube. Multiple auxiliary lamp tubes are divided into a first auxiliary lamp tube group and a second auxiliary lamp tube group, which are respectively arranged on the first plate and the third plate.
[0008] Furthermore, the angle between the length direction of the auxiliary lamp in the first auxiliary lamp group / second auxiliary lamp group and the positive direction of the main lamp is an acute angle.
[0009] Furthermore, each of the first auxiliary lamp group and the second auxiliary lamp group includes a first distribution unit, a second distribution unit, and a third distribution unit arranged sequentially and at intervals. The third distribution unit is close to the driving device. The second distribution unit includes one auxiliary lamp located in the middle of the first plate, and the length direction of the auxiliary lamp is perpendicular to the positive direction of the main lamp. Both the third distribution unit and the first distribution unit include multiple auxiliary lamps arranged in parallel. The length direction of the multiple auxiliary lamps in the first distribution unit forms an acute angle with the positive direction of the main lamp, and the length direction of the multiple auxiliary lamps in the third distribution unit forms an obtuse angle with the positive direction of the main lamp.
[0010] Furthermore, the width of the first plate / third plate and the length of the auxiliary lamp tube meet the following constraints: L = b + 20 ~ 40, Where b is the width of the first plate / third plate in mm, and L is the length of the auxiliary lamp in mm.
[0011] Furthermore, the bracket includes a first support rod and a first connecting cylinder disposed at one end of the first support rod, the other end of the first support rod is connected to the second plate, the central axis of the first connecting cylinder is perpendicular to the length direction of the first support rod, and the output shaft of the drive device is fixedly fitted to the first connecting cylinder.
[0012] Furthermore, the support includes a second support rod and a third support rod spaced apart. The two ends of the second plate are respectively connected to the first ends of the second support rod and the first ends of the third support rod. A second connecting cylinder is provided at the second end of the second support rod. The central axis of the second connecting cylinder is perpendicular to the length direction of the second support rod. The output shaft of the drive device is fixedly fitted to the second connecting cylinder. The second end of the third support rod is used for rotatable connection with the seedling frame.
[0013] Furthermore, the monitoring component includes an image acquisition device and a sensor group that are respectively connected to the controller signal. The image acquisition device is used to acquire images of the seedlings, and the sensor group is used to detect light intensity.
[0014] Furthermore, it also includes a fixing component for connecting with the seedling rack. The fixing component includes a first clamping component and a second clamping component that are arranged opposite to each other and have the same structure, respectively disposed at the second end of the second support rod and the second end of the third support rod.
[0015] Furthermore, the first clamping assembly includes a fourth plate and two clamping portions spaced apart on one side of the fourth plate. Each clamping portion includes a fifth plate and at least one hexagon socket head cap screw passing through the fifth plate. The fifth plate is fixed perpendicularly to the fourth plate. The hexagon socket head cap screws on the two clamping portions are arranged opposite each other. The fourth plate of the first clamping assembly is rotatably connected to the second end of the third support rod. A driving device is fixed on the fourth plate of the second clamping assembly. The driving device is located on the side of the fourth plate away from the clamping portions. The output shaft of the driving device is perpendicular to the fourth plate and is fixedly fitted with the second connecting sleeve.
[0016] Compared with existing technologies, this invention provides a supplemental lighting device for a smart factory of vertical rice seedling raising. Multiple auxiliary lamps are evenly distributed on both sides of the main lamp in a cantilevered structure along its length. The auxiliary lamps form an angled structure with the main lamp, constituting the main structure of the supplemental lighting component. Its overall design mimics the branching structure of leaf veins, ensuring that it does not obstruct the airflow within the vertical seedling raising frame. This minimizes the impact of airflow around the seedlings on photosynthesis. Furthermore, a drive device moves the supplemental lighting component according to a preset time sequence, changing the range of light radiation and achieving uniform supplemental lighting for the seedlings. Simultaneously, the controller, based on the seedling growth stage, uses a dimming component to synchronously control the supplemental lighting component, adapting to the light requirements of different growth stages and thus improving seedling growth quality and photosynthetic efficiency. This invention not only improves the automation and intelligence of the supplemental lighting process during seedling raising but also provides strong technical support for the efficient production of smart factories for vertical seedling raising. It is highly practical and worthy of promotion. Attached Figure Description

[0029] Example 1 A supplemental lighting device for a smart factory for vertical rice seedling raising, such as Figure 1 As shown, it can be arranged in the seedling raising site as needed to adapt to the seedling raising scenario and help improve the convenience of seedling raising operations.
[0030] The supplemental lighting device for a smart rice seedling raising factory includes: a drive unit 3, a support 2, a supplemental lighting component 1, a dimming component, a monitoring component, and a controller. The controller is connected to the monitoring component, the dimming component, and the drive unit 3 via signals. The supplemental lighting component 1 is located at one end of the support 2, and the other end of the support 2 is connected to the drive unit 3 via signals.
[0031] The monitoring components include an image acquisition device and a sensor array. The image acquisition device, mounted on support 2, is used to acquire images of the seedlings. The sensor array includes multiple sensors that detect light intensity and synchronously transmit the seedling images and light intensity data to the controller. The controller receives the light intensity information from the sensors, processes the seedling images, determines the seedling growth stage, and records the seedling growth stage and light intensity data in a time sequence. The light intensity and corresponding time information are combined to form real-time parameters. After comparing these parameters with preset parameters, a supplementary lighting control strategy is determined. On the other hand, the controller can output control signals according to a preset time sequence, synchronously driving drive 3 to adjust the angle of supplementary lighting component 1, allowing the seedlings to grow in an environment close to natural light, promoting the accumulation of photosynthetic products.
[0032] Specifically, the aforementioned controller's determination of the seedling growth stage based on seedling images is a popular research and industrialization area, with a wealth of publicly available information in academic papers and patents. In this embodiment, the method of identifying the leaf age of rice seedlings based on machine vision, published under CN114596509A, can be used to efficiently and accurately identify the leaf age of rice seedlings, thereby determining the corresponding growth stage of the seedlings.
[0033] Since the light requirements of seedlings vary at each growth stage, historical data can be used to determine the light requirements for each growth stage, and then these can be used as preset parameters for the light requirements of seedlings at each growth stage.
[0034] Specifically, the controller generates real-time parameters from the light intensity and corresponding time information. After comparing these parameters with preset parameters, it determines the supplementary light difference. The supplementary light difference is the technical basis for formulating the supplementary light control strategy. Based on the supplementary light difference, the controller sends a supplementary light control command to the dimming component, which then controls the light intensity of the supplementary light component 1.
[0035] The supplementary lighting component 1 is connected to the dimming component via a signal. The dimming component can receive the supplementary lighting control signal from the controller and control the supplementary lighting component 1 to execute the supplementary lighting control strategy. This allows the supplementary lighting component 1 to dynamically adjust the light power according to the growth stage of the seedlings and the ambient light intensity, accurately matching the photosynthetic needs of different seedlings and improving the efficiency of light energy utilization.
[0036] Specifically, the drive device 3 can be a servo motor, which is connected to the controller via a signal. The servo motor is driven by the controller's commands to drive the bracket 2 and the supplementary lighting component 1 to rotate synchronously, thereby achieving attitude adjustment of the supplementary lighting component 1.
[0037] In this embodiment, the core function of the selected servo motor is to precisely control the angle of the bracket 2 relative to the horizontal plane. The servo motor receives the control signal, rotates to the preset angle, and maintains the position after reaching the preset angle.
[0038] The reason for choosing a servo motor is: 1. Servo motors are highly integrated and easy to use. A servo motor is a "fully integrated kit" that includes a motor, reduction gear set, position feedback sensor and control circuit. There is no need to design drive circuits and feedback systems. It can work by providing power and simple control signals.
[0039] 2. Servo motors are simple to control and have high precision. They use pulse width modulation (PWM) signal control, requiring only one signal line. By changing the pulse width, the target angle can be precisely specified, typically rotating within the range of 0°-180°, with control precision reaching 1° or even higher.
[0040] 3. Servo motors have high output torque. The multi-stage reduction gear set inside the servo motor converts the high-speed, low-torque motor output into a low-speed, high-torque output, allowing even a small servo motor to generate great power.
[0041] 4. The servo motor has strong self-locking / holding capabilities. When the servo motor reaches the designated position, its control circuit continuously compares the current position with the target position. If it is disturbed by external forces, it will automatically reverse the drive motor and try to "lock" at the target angle until it receives a new command, thus enhancing safety.
[0042] In this embodiment, the preferred servo motor is the Savox SH-0255MG from Savox Corporation of Taiwan, China. It has a torque of approximately 6.0 kg·cm @ 6.0V, a speed of approximately 0.14 sec / 60° @ 6.0V, metal gears, high output torque, reliable overall quality, and stable performance.
[0043] In one embodiment, a servo motor-driven solution is selected. The matching bracket 2 can be a single-arm structure, comprising a first support rod and a first connecting cylinder at one end of the first support rod. The other end of the first support rod is connected to the supplementary lighting component 1. The central axis of the first connecting cylinder is perpendicular to the length direction of the first support rod. The output shaft of the servo motor is fitted and fixed to the first connecting cylinder, thus connecting the bracket 2 to the servo motor. The supplementary lighting component 1 is then positioned at the other end of the first support rod, its length parallel to the output shaft of the servo motor. When the servo motor receives a control signal, its output shaft rotates, simultaneously rotating the bracket 2 and the supplementary lighting component 1 to a preset angle and maintaining this position.
[0044] In order not to obstruct the air circulation channel inside the vertical seedling frame, the structure of the supplementary lighting component 1 is designed to resemble the branching structure of leaf veins. The structure includes a mounting panel, a main lamp tube 11 and multiple auxiliary lamp tubes 12. The main lamp tube 11 and the auxiliary lamp tubes 12 are full-spectrum LED lamp tubes and are respectively connected to the dimming component. The mounting panel serves as the core support and is fixedly connected to the other end of the first support rod. The length direction of the mounting panel is parallel to the output shaft of the servo motor and the angle between the two is 0°. The main lamp tube 11 serves as the main source of light output and is set on the mounting panel. The length direction of the main lamp tube 11 is consistent with the length direction of the mounting panel.
[0045] In order to create an envelope-like light radiation atmosphere around the seedlings, the cross-sectional structure of the mounting panel is designed as an flared U-shape, with the opening of the U-shape facing the seedling frame.
[0046] Specifically, the mounting panel includes a first plate, a second plate, and a third plate arranged sequentially. The first and third plates are symmetrically arranged with respect to the central plane of the second plate, and the angle between the first and third plates is obtuse. The first and third plates are fixedly connected to one opposite end of the second plate, and one of the other pairs of opposite ends of the second plate is optionally fixedly connected to the other end of the first support rod. The main lamp tube 11 is mounted on the second plate, and the length direction of the main lamp tube 11 is consistent with the length direction of the second plate.
[0047] Multiple auxiliary lamps 12 are divided into a first auxiliary lamp group and a second auxiliary lamp group, which are respectively arranged on the first plate and the third plate. The first auxiliary lamp group and the second auxiliary lamp group have the same structure and are arranged symmetrically with respect to the central plane of the second plate. The end of the main lamp 11 furthest from the driving device 3 is defined as the positive direction of the main lamp 11. The angle between the length direction of the auxiliary lamps 12 in the first auxiliary lamp group and the positive direction of the main lamp 11 is an acute angle.
[0048] The auxiliary lamp tube 12 is preferably an LED lamp panel, and the main lamp tube 11 is combined with multiple LED lamp panels to form a complete lighting system.
[0049] By setting the auxiliary lamp tube 12 as a cantilever structure, the hollow structure between adjacent auxiliary lamp tubes 12 reduces the solid area and reduces the impact of blocking the upward airflow channel.
[0050] Specifically, taking the auxiliary lamp tube 12 on the first plate as an example, one end of the auxiliary lamp tube 12 is connected to the first plate through a connecting structure, and the other end of the auxiliary lamp tube 12 extends out of the first plate in a free cantilever state. The posture of the auxiliary lamp tube 12 is ensured by the cooperation of the first plate and the connecting structure.
[0051] The first plate and the third plate have the same structure. To ensure that the auxiliary lamp tube 12 is a cantilever structure, the width of the first plate and the length of the auxiliary lamp tube 12 can be set to meet the following constraints: L = b + (20~40) Where b is the width of the first plate / third plate in mm, and L is the length of the auxiliary lamp tube 12 in mm.
[0052] The main lamp tube 11 provides basic lighting coverage, while the auxiliary lamp tube 12 extends to both sides to form a wide-range lighting network, which can provide supplemental lighting for the entire area of the seedlings.
[0053] In another implementation, unlike the arrangement described above, both the first auxiliary lamp group and the second auxiliary lamp group include a first distribution unit, a second distribution unit, and a third distribution unit arranged sequentially and at intervals.
[0054] Taking the first auxiliary lamp group on the first plate as an example, the third distribution unit is close to the driving device 3, and the second distribution unit includes an auxiliary lamp 12. The auxiliary lamp 12 is located in the middle of the first plate, and the length direction of the auxiliary lamp 12 is perpendicular to the positive direction of the main lamp 11.
[0055] The third distribution unit and the first distribution unit are mirror images of the second distribution unit. Specifically, both the third distribution unit and the first distribution unit include multiple parallel auxiliary lamps 12. The length direction of the multiple auxiliary lamps 12 in the first distribution unit is at an acute angle to the positive direction of the main lamp 11, while the length direction of the multiple auxiliary lamps 12 in the third distribution unit is at an obtuse angle to the positive direction of the main lamp 11.
[0056] In use, the drive device 3 is fixed on the seedling frame. The controller controls the main lamp tube 11 and the auxiliary lamp tube 12 to work according to the preset conditions. At the same time, the controller automatically outputs control signals through the built-in preset time sequence to synchronously drive the servo motor to rotate and adjust the rotation angle of the supplementary lighting component 1 relative to the seedlings to achieve uniform supplementary lighting, meet the photosynthetic needs of the seedlings, allow the seedlings to grow in an environment close to natural light, promote the accumulation of photosynthetic products, adapt to the light needs of different growth stages of the seedlings, and thus improve the growth quality and photosynthetic efficiency of the seedlings.
[0057] In addition, as another implementation scheme, in order to improve stability and adaptability, the bracket 2 can be a double-arm structure, specifically including a second support rod and a third support rod arranged at intervals, with the supplementary lighting component 1 set at one end of the second support rod and the third support rod.
[0058] Specifically, the two ends of the second plate are connected to the first ends of the second support rod and the third support rod, respectively. The connection and positional relationships of the other components of the supplementary lighting assembly 1 are the same as those described above.
[0059] A second connecting cylinder is installed at the second end of the second support rod, with the central axis of the second connecting cylinder perpendicular to the length direction of the second support rod. The output shaft of the servo motor is fitted and fixed to the second connecting cylinder to achieve the connection between the bracket 2 and the servo motor.
[0060] A connecting shaft is provided at the second end of the third support rod. One end of the connecting shaft is fixed to the third support rod, and the central axis of the connecting shaft is perpendicular to the length direction of the third support rod.
[0061] Before use, the servo motor can be fixed to one end of the seedling frame, the first mounting hole can be opened at the other end of the seedling frame, and the first bearing can be installed in the first mounting hole. The first bearing can then be fixed to the connecting shaft.
[0062] For easier installation, a fixing component can also be added to the device.
[0063] Specifically, the fixing components include a first clamping component and a second clamping component that are arranged opposite to each other and have the same structure, respectively disposed at the second end of the second support rod and the second end of the third support rod.
[0064] The first clamping assembly includes a fourth plate and two clamping parts respectively disposed at both ends of the fourth plate. Each clamping part includes a fifth plate and at least one hexagonal bolt passing through the fifth plate. The fifth plate is fixed perpendicularly to the fourth plate, and the hexagonal bolts on the two clamping parts are arranged opposite to each other.
[0065] The fourth plate of the first clamping assembly has a second mounting hole, and the second bearing is installed in the second mounting hole to fix the second bearing onto the connecting shaft.
[0066] The servo motor is fixed on the fourth plate of the second clamping assembly, and the output shaft of the servo motor is perpendicular to the fourth plate.
[0067] Before use, the first clamping component and the second clamping component can be respectively set at both ends of the seedling frame. Then, adjust the hexagonal bolts on the first clamping component and the second clamping component respectively so that the hexagonal bolts are tightened against the seedling frame to fix the first clamping component and the second clamping component to the seedling frame. This maintains a stable mechanical connection between the seedling frame and the supplementary lighting equipment, effectively limiting the relative displacement between the seedling frame and the supplementary lighting component 1. This prevents positional shifts caused by equipment vibration or external contact, ensuring that the supplementary lighting component 1 always illuminates the seedlings at the optimal distance and angle, and guaranteeing the stability of the lighting effect.
[0068] The controller can be an external device or integrated into the functional enclosure. As the core control unit, it receives data from the sensor group, generates control signals, and coordinates the operation of various components.
[0069] The servo motor, controller, main lamp 11 and auxiliary lamp 12 are respectively connected to the power signal to ensure the power supply of the power supply device.
[0070] The seedling rack forms a space for raising seedlings. The seedling rack, together with supplemental lighting equipment, can be used to build an intelligently controllable equipment system that is adapted to vertical seedling raising operations.
[0071] This invention enables uniform supplemental lighting through mechanical movement, combining full-spectrum supplemental lighting to meet the photosynthetic needs of seedlings. Furthermore, it employs intelligent control strategies to adapt to the light requirements of seedlings at different growth stages, thereby improving seedling growth quality and photosynthetic efficiency. This invention not only enhances the automation and intelligence of the supplemental lighting process during seedling cultivation but also provides strong technical support for the efficient production of vertical seedling smart factories.
[0072] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
