Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, and more specifically to an automatic lighting device for an intelligent cabinet. Background Technology

[0002] A plant growth chamber is a specialized cultivation device for experiments on plant growth and seed germination. Its main function is to provide uniform light and constant temperature and humidity to allow plants to grow under specific conditions. Also known as a plant growth box or plant growth chamber, it is widely used in agriculture, forestry, horticulture, and biological sciences. It is of great significance for research on plant growth and development, pest and disease control, and new variety breeding. Laboratory workers need to use this intelligent growth chamber to conduct experimental research on different topics, such as short-term dynamic monitoring and long-term, full-cycle cultivation.

[0003] The main workflow and characteristics of existing traditional plant cultivation cabinets are as follows: First, ensure that the plant cultivation cabinet is placed in a clean, tidy, dry and well-ventilated work room with an ambient temperature of 10-30℃, relative humidity below 85%, and no strong corrosive gases. The experimenter places individual containers on the cabinet's platform and manually positions each container to ensure that there is an appropriate gap between them to facilitate air convection and circulation. The lights on the top of the cabinet are turned on to emit a constant light. The plants enter the cultivation state. The staff needs to time the process according to the experimental purpose and observe the plants at different growth stages. When it is necessary to adjust the growth conditions, the set values ​​need to be adjusted. At specific time points, the cabinet needs to be opened to take out the plant samples.

[0004] Analysis of existing technologies reveals the following problems with traditional plant cultivation cabinets: First, the cultured samples in the cabinet can only grow in the same environment. When a control experiment is needed, the samples must be divided into two batches, which is not conducive to comparing experimental results and prolongs the experimental cycle. It is also impossible to precisely control the light conditions of each cultured object, and the cabinet must be opened to observe a single sample, which can easily affect other samples. When the plants grow to different stages, the internal environment of the cabinet needs to be adjusted, which requires manual timing and increases the experimental error rate. Adjusting the light angle also requires opening the cabinet and taking out the plant sample, which increases the risk of the plant sample being affected by the external environment. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic lighting device for a smart cabinet to solve the problems existing in the background art.

[0006] The present invention provides the following technical solution: an automatic lighting device for an intelligent cabinet, comprising a light-emitting component and a structural component, an adjustment component installed below the light-emitting component, a plant cultivation area installed below the adjustment component, the light-emitting component including a light-emitting lamp, the structural component including a cabinet shell, a CCD camera installed at the top inside the cabinet shell, and a beam-splitting component installed below the CCD camera;

[0007] Furthermore, the lighting component includes a light conversion axis, with a lower light tube and an upper light tube installed below the light conversion axis, and a total reflection cone installed at the bottom of both the lower and upper light tubes.

[0008] Furthermore, the beam splitting assembly includes an upper beam splitter, a lower beam splitter is installed below the upper beam splitter, and three light output ports are opened on the outer side of both the upper and lower beam splitters, with all light output ports being staggered from each other.

[0009] Furthermore, the lower end of the lower light-passing tube is located inside the lower beam splitter, and the lower end of the upper light-passing tube is located inside the upper beam splitter. Both the lower and upper light-passing tubes are equipped with three light-emitting tubes, which extend through the light-emitting port to the outside of the beam splitting assembly.

[0010] Furthermore, a rotating grid is installed inside the light outlet, a driven saw blade and a grid shaft are installed above the rotating grid, and a drive controller is installed above the grid shaft located in the middle of the driven saw blade.

[0011] Furthermore, an angle adjustment rod is installed at the light outlet, the angle adjustment rod includes a dimming handle, and a steering prism is installed in the middle section of the dimming handle.

[0012] Furthermore, the end of the light-emitting tube is located inside the angle adjustment rod. The light-emitting tube and the angle adjustment rod are connected. The angle adjustment rod can rotate outside the light-emitting tube. There are a total of angle adjustment rods, and the angle adjustment rods are staggered from each other. A light-blocking plate is installed between each angle adjustment rod. The light-blocking plate is connected to the inner side of the cabinet shell.

[0013] Furthermore, the structural component includes a vessel tray, with partition baffles installed above the vessel tray. The partition baffles are at an angle to each other, and a slot is opened between each partition baffle. A culture box is installed in the slot, and a single culture box can be removed.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention, by incorporating culture boxes, facilitates the spatial partitioning of the culture cabinet. Utilizing the principles of total internal reflection and diffuse reflection, the light provided by the lamps is dispersed and redirected within the beam-splitting component, allowing light of specific colors, brightness, and different angles to reach the interior of each culture box. This creates different growth environments for the cultured organisms and also facilitates the removal of individual culture boxes for observation or adjustment. This solves the problem of traditional culture cabinets being unable to precisely control the lighting conditions for each cultured organism.

[0016] 2. This invention, by incorporating a CCD camera and a light-changing axis, facilitates the automatic detection of different growth stages of the cultured object. When the plant morphology changes, the CCD camera can accurately identify and automatically control the drive controller to rotate. At the same time, the rotation of the light-changing axis can be adjusted to obtain different lighting angles, thus solving the problems of traditional culture cabinets requiring manual timing and manual opening of the culture cabinet to observe the plant growth status.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic lighting device for an intelligent cabinet involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2 The present invention provides an automatic lighting device for an intelligent cabinet, including a light-emitting component 1 and a structural component 5. An adjustment component 3 is installed below the light-emitting component 1, and a plant cultivation area 4 is installed below the adjustment component 3. The light-emitting component 1 includes a light-emitting lamp 101, and the structural component 5 includes a cabinet shell 501. A CCD camera 301 is installed at the top inside the cabinet shell 501, and a beam-splitting component 2 is installed below the CCD camera 301.

[0030] In this embodiment, it should be specifically explained that: there are two light-emitting lamps 101, which can emit light of different colors. The CCD camera 301 can observe the growth morphology of the plants inside the plant cultivation area 4, thereby inferring the growth stage of the plants. The CCD camera 301 can control the relative positions of the two light-emitting lamps 101 according to the growth stage of the plants, thereby changing the light color of the plants inside the plant cultivation area 4. After the light from each light-emitting lamp 101 enters the interior of the beam splitting component 2, it is split into three beams, which then shine into the plant cultivation area 4 from the beam splitting component 2. At the same time, the angle and intensity of the light entering the plant cultivation area 4 can be controlled by adjusting the beam splitting component 2. This device can be used in a single layer or in multiple layers depending on the application conditions of the cabinet.

[0031] The CCD camera 301 can capture changes in plant growth, such as the number, color, and size of leaves. It has high sensitivity and can work stably and continuously in different external environments. Red light has a higher wavelength and lower energy. When the lamp illuminates the plant with red light, it can promote the synthesis and accumulation of plant nutrients, enhance plant biomass and flowering ability. Blue light is a short wavelength light with higher energy. When the lamp illuminates the plant with blue light, it can promote plant germination, seedling growth and leaf unfolding. It can also stimulate the plant's photosensitivity and auxin synthesis, thereby improving the plant's growth rate and stress resistance. Therefore, the two light-emitting lamps 101 in this embodiment use blue light and red light as examples.

[0032] The main difference between this embodiment and the prior art is that this embodiment uses the plant growth state as the independent variable to control the color, angle and brightness of the plant light, and uses one light source to illuminate three containers at the same time, specifically in the light-splitting component 2 and the adjustment component 3;

[0033] The above structure is the main structure of this embodiment, which solves the problems that traditional cultivation cabinets cannot adjust the lighting environment in zones and cannot be automated due to reliance on manual observation of plants. The CCD camera 301 is existing technology, and the specific structure and connection method of the CCD camera 301 will not be described in detail in this embodiment.

[0034] Reference Figure 3 and Figure 4 The lighting assembly 1 includes a light conversion shaft 102, with a lower light-passing tube 103 and an upper light-passing tube 104 installed below the light conversion shaft 102. The beam splitting assembly 2 includes an upper beam splitter 201, with a lower beam splitter 202 installed below the upper beam splitter 201. Each of the upper beam splitter 201 and the lower beam splitter 202 has three light-exit ports 203 on its outer side, and all the light-exit ports 203 are staggered by 60 degrees from each other. The lower end of the lower light-passing tube 103 is installed inside the lower beam splitter 202, and the lower end of the upper light-passing tube 104 is installed inside the upper beam splitter 201. Each of the lower light-passing tube 103 and the upper light-passing tube 104 has three light-exit tubes 105 installed at its lower end. The light-exit tubes 105 extend through the light-exit ports 203 to the outer side of the beam splitting assembly 2.

[0035] In this embodiment, it should be specifically explained that: the lower light tube 103 and the upper light tube 104 correspond to the light-emitting lamps 101 directly above them, and the two light-emitting lamps 101 emit two different colors of light. When the light conversion axis 102 rotates 180 degrees, the light-emitting lamps 101 above the lower light tube 103 and the upper light tube 104 are interchanged, realizing the interchange of light colors. The inner walls of the lower light tube 103, the upper light tube 104 and the light-emitting tube 105 are all coated with a metal coating. In this embodiment, an AR coating is used as an example, which helps to ensure light reflection and reduce light loss during propagation. The light will enter the light-emitting tube 105 after total internal reflection and diffuse reflection.

[0036] Reference Figure 5 Both the bottom of the lower light tube 103 and the upper light tube 104 are equipped with total reflection cones 204.

[0037] In this embodiment, it should be specifically noted that: the surface of the total reflection cone 204 is coated with an AR coating, and the triangular base of the total reflection cone 204 cross section is 45 degrees. When light shines from the top of the lower light tube 103 onto the total reflection cone 204 at the bottom of the lower light tube 103, the light undergoes total reflection and diffuse reflection, and finally shines into the interior of the light output tube 105, and passes through the light output port 203 along the light output tube 105 to the next propagation position.

[0038] Reference Figure 6 Inside the light outlet 203, a rotating grid 302 is installed. Above the rotating grid 302, a driven saw blade 3021 and a grid shaft 3023 are installed. Above the grid shaft 3023, which is located in the middle of the driven saw blade 3021, a drive controller 3022 is installed.

[0039] In this embodiment, it should be specifically explained that when the drive controller 3022 is controlled by the CCD camera 301 and starts working, the drive controller 3022 drives the grid shaft 3023 connected to it to rotate. The rotation of the grid shaft 3023 drives the driven saw blade 3021 to move left and right, thereby driving the other grid shafts 3023 to rotate. The rotation of the grid shaft 3023 drives the rotating grid 302 to rotate, causing the rotating grid 302 to tilt at an angle. The size of the gap between the rotating grids 302 also changes with the angle, thereby changing the amount of light passing through the light output tube 105. The CCD camera 301 controls the drive controller 3022 by observing the growth status of the plant to coordinate the light requirements of the plant at different stages. The drive controller 3022 is existing technology, and the specific structure and connection method of the drive controller 3022 will not be described in detail in this embodiment.

[0040] Reference Figure 7An angle adjustment rod 303 is installed at the light outlet 203, and the end of the light outlet tube 105 extends into the interior of the angle adjustment rod 303 and connects with the angle adjustment rod 303. The angle adjustment rod 303 can rotate outside the light outlet tube 105. There are a total of 6 angle adjustment rods 303, and the angle adjustment rods 303 are staggered by 60 degrees. A light blocking plate 502 is installed between each angle adjustment rod 303, and the light blocking plate 502 is connected to the inner side of the cabinet shell 501.

[0041] In this embodiment, it should be specifically explained that: light enters the interior of the beam splitter 2 through the light outlet tube 105 and then through the light outlet 203, and then enters the interior of the angle adjustment rod 303. The light is reflected downwards by the inside of the angle adjustment rod 303. The light blocking plate 502 separates each angle adjustment rod 303 from each other to prevent light interference in different areas.

[0042] Reference Figure 8 The angle adjustment lever 303 includes a dimming handle 3031, and a steering prism 3032 is installed in the middle section of the dimming handle 3031.

[0043] In this embodiment, it should be specifically explained that when light shines from the light-emitting tube 105 into the steering prism 3032, the light undergoes total internal reflection inside the steering prism 3032, changing its propagation angle, and finally shines downward. When the dimming handle 3031 is rotated, the light-emitting surface and its horizontal position are angled, so the angle at which the light shines downward also changes, thereby realizing the zoned adjustment of the light angle for the plants.

[0044] Reference Figure 9 The structural component 5 includes a vessel tray 503, with partition baffles 402 installed above the vessel tray 503. The partition baffles 402 are at a 60-degree angle to each other, and a slot is opened between each partition baffle 402. A culture box 401 is installed in the slot, and a single culture box 401 can be removed.

[0045] In this embodiment, it should be specifically explained that: the culture object is planted in the culture box 401, light shines into the culture box 401 from the adjustment component 3, and the partition baffle 402 and the vessel tray 503 are used to fix the culture box 401.

[0046] Working principle of the invention:

[0047] The main problem solved by this embodiment is that the device divides the space of the culture cabinet by opening culture boxes 401, and uses the principles of total internal reflection and diffuse reflection of light to disperse and change the direction of the light provided by the light source inside the beam splitting component 2, so that light of specific color, brightness and different angles can reach the interior of each culture box 401, thus solving the problem that traditional culture cabinets cannot accurately control the light conditions of each culture object.

[0048] Secondly, by setting up a light-changing axis 102, a drive controller 3022, and a CCD camera 301, the different stages of the cultured object are detected. When the plant morphology changes, the CCD camera 301 can accurately identify and automatically control the rotation of the drive controller 3022 and the light-changing axis 102, thereby adjusting the lighting conditions and solving the problem that traditional culture cabinets require manual timing and manual opening of the culture cabinet to observe the plant growth status.

[0049] The specific steps are as follows: First, plant the plant samples that need to be cultivated or observed are planted in the culture box 401 and provided with suitable soil conditions and appropriate amount of water. Then, according to their growth stage, the culture box 401 is installed between the partition baffles 402 above the container tray 503 so that the samples are installed in the corresponding three areas. The plants receive the corresponding color of light in the initial stage, while the other three areas can be used to place a batch of plant samples at other growth stages for cultivation.

[0050] Taking an ungerminated seed as an example, if the initial form of the plant is the seed stage, respiration is the main function, and photosynthesis has not yet begun. The seed mainly relies on nutrients and water in the soil, and its light requirement is relatively low. When the CCD camera 301 recognizes the state of the plant in the culture box 401 as a seed, the light conversion axis 102 remains stationary. The blue light from the light source 101 shines from the top to the bottom of the lower light tube 103. When the light shines on the total internal reflection cone 204, the light undergoes total internal reflection and diffuse reflection, thus changing direction and shining into the interior of the light outlet tube 105, and then passing through the light outlet tube 105. The light passes through the light outlet 203 and then through the steering prism 3032. The steering prism 3032 reflects the blue light into the culture box 401. At this time, the drive controller 3022, controlled by the CCD camera 301, rotates appropriately. This rotation angle creates a small gap between the rotating grids 302, resulting in a lower amount of light transmission. Meanwhile, the experimenter can rotate the dimming handle 3031 as needed to adjust the angle at which the light shines on the culture box 401. To facilitate the differentiation of the light intensity, the following uses levels one to four to represent the light intensity of the rotating grids 302 at different angles. The light intensity at the seed stage is level one.

[0051] When a plant is in the budding stage, the buds need less light to promote leaf growth and root development. At this time, respiration is still greater than photosynthesis. The CCD camera 301 observes the changes in plant morphology and controls the drive controller 3022 to rotate a certain angle, so that the light intensity in the culture box 401 is slightly increased to level two. The position of the light conversion axis 102 remains unchanged, and the color of the light remains unchanged.

[0052] When the plant sample is in the seedling stage, the seedling needs a certain amount of light to promote leaf growth and root development. As photosynthesis gradually increases, the CCD camera 301 observes that the size and color of the plant's leaves have changed significantly. Therefore, the control drive controller 3022 continues to rotate at a certain angle, and the gap of the angle adjustment rod 303 is further increased, so that the light received inside the culture box 401 is stronger. At this time, the light intensity is level three. At the same time, the plant at this stage still needs a shorter wavelength and higher energy to promote leaf unfolding. Therefore, the light conversion axis 102 remains stationary, and the light received by the culture box 401 is blue. If the experimenter needs to change the light angle, the dimming handle 3031 is rotated, so that the turning prism 3032 rotates accordingly. The incident light angle from the light output tube 105 remains unchanged, while the outgoing light reflected by the turning prism 3032 will rotate accordingly.

[0053] When the plant reaches the vegetative growth stage, it needs more light to promote leaf growth, root development, and overall plant growth. After the CCD camera 301 observes the further growth of the plant, it controls the drive controller 3022 to rotate to the maximum angle. At this time, the light passing through the light outlet 203 is almost completely through, and the light intensity reaches the highest level, which is level four. At the same time, the CCD camera 301 controls the light conversion axis 102 to rotate 180 degrees, so that the two light-emitting lamps 101 interchange positions. Then, the light color above the lower light tube 103 and the upper light tube 104 is interchanged, and the light color received by the culture box 401 becomes red.

[0054] When plants enter the flowering and fruiting period, their demand for light remains high. Under the observation of CCD camera 301, the rotating grid 302 is kept at its maximum angle, the light intensity is kept at level four, the position of the light conversion axis 102 remains unchanged, and the red light can continuously promote the synthesis and accumulation of plant nutrients, enhance the plant's biomass and flowering ability. At the same time, the angle of the angle adjustment rod 303 can be adjusted as needed.

[0055] When plants enter their dormant senescence period, their growth almost stops, their need for light gradually decreases, and the proportion of respiration gradually increases. Therefore, after the CCD camera 301 observes the morphological characteristics of the plant, it controls the drive controller 3022 to rotate, and the rotating grid 302 gradually decreases in angle, gradually reducing the light intensity to level one, until the rotating grid 302 is completely closed. At the same time, the CCD camera 301 controls the light conversion axis 102 to rotate, causing the light paths in the lower light tube 103 and the upper light tube 104 to switch. The light color inside the culture box 401 changes from red to blue, while the other group changes to red light. Other groups of culture boxes 401 can be placed in for observation as needed for the experiment.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
