Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, specifically a three-dimensional plant cultivation factory. Background Technology

[0002] Modern agriculture has gradually developed soilless cultivation plants to overcome the limitations imposed by soil, light, and space on plant cultivation. Soilless cultivation refers to a method of cultivation where plants are fixed in place by a substrate such as water, peat moss, forest compost, or vermiculite, allowing the roots to directly contact the nutrient solution. Soilless cultivation frees plant cultivation from the constraints of soil, greatly expanding the scope of agricultural production and offering broad development prospects. Its key feature is the replacement of the soil environment with an artificially created root growth environment. This not only meets the crop's needs for nutrients, water, and air but also allows for the control and regulation of these conditions, promoting crop growth and achieving a balance between vegetative and reproductive growth.

[0003] Aeroponics is a type of soilless cultivation technology. It uses a spraying device to atomize nutrient solution into small droplets, which are then sprayed directly onto the plant roots to provide the water and nutrients needed for plant growth. Aeroponics further reduces the plant roots' need for solid matter, significantly increases the contact between the plant roots and the nutrient mist, thereby improving the plant's nutrient absorption efficiency. It can also improve the water-air imbalance in soilless cultivation and facilitates automated control and three-dimensional cultivation when combined with plant factories.

[0004] To make full use of vertical space and improve the planting efficiency per unit area in plant cultivation factories, existing cultivation beds or cultivation racks in plant cultivation factories also offer technical solutions that combine aeroponic devices with movable and vertical structures.

[0005] For example, in the technical solution of aeroponic devices combined with a vertical layered structure, patent publication number CN112568116A discloses an intelligent multi-layered combined vertical aeroponic system and control method. The aeroponic system includes an aeroponic support frame, which is a multi-layered combined vertical structure, and several small aeroponic devices placed on the support beams of the aeroponic support frame. The technical solution of this patent only divides the cultivation space into superimposed or parallel modular subspaces through a fixed structure. The aeroponic devices or light source structures are arranged in an overlapping manner. Especially when the partition structure uses only lightweight, non-sealed materials, the effects of aerosol and light can interfere with each other, such as aerosol blocking light or corroding circuit equipment. In addition, the layered aeroponic devices or light source structures cannot fully utilize the diffusion capacity of aerosol or light.

[0006] Regarding technical solutions for aeroponic devices combined with movable or conveyor structures, patent CN103563679B provides an automated seedling bed. This patent combines an aeroponic device with a continuous conveyor structure. The position and angle of the plant receiving nutrients such as light and mist can be adjusted via a chain-like, height-varying conveyor structure, thus forming a movable planting structure that fully utilizes vertical space. However, the supporting mechanism used to carry the plants and move relative to the light source or aeroponic device with the conveyor structure is a discontinuous structure. This allows the mist to diffuse throughout the entire cultivation space, making it impossible to effectively limit the effective range of aeroponic cultivation. This results in decreased mist density or mist waste. Furthermore, the mist diffused into the area affected by the plants also obstructs and scatters light, weakening both aeroponic and light-based cultivation effects to varying degrees.

[0007] Based on the above analysis, in existing plant factories, the fixed structure used to achieve layered arrangement of cultivation beds or racks with aeroponic technology cannot fully utilize the diffusion capacity of mist or light and poses a risk of mutual interference. Existing movable aeroponic devices or conveyor structures also cannot functionally partition the cultivation space and fully utilize the vertical space of the plant factory through movable structures that support plants. Especially when different parts of the plant have different needs for mist, light, and nutrients, the existing partitioned or movable structures cannot achieve the connectivity or closure of several functional spaces under different cultivation states or modes through structural adjustments. As a result, the cultivation beds or racks in the plant factory cannot be adaptively adjusted during cultivation, planting, harvesting, and cleaning processes to implement several automated planting modes for the aforementioned processes.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0009] To address at least some of the shortcomings of existing technologies, this application provides a three-dimensional plant cultivation factory. The plant cultivation factory is equipped with a control center for several functional structures, including: an information acquisition center for acquiring plant status and environmental information; a nutrient preparation center for preparing the nutrient solution required for each growth stage of the plant and controlling the aerosol parameters acting on the plant; a transmission and control center for controlling the movement parameters of the planting module carrying the plant in the planting space; and a server for obtaining several planting modes adapted to different planting stages of the plant based on the plant status and environmental information obtained from the information acquisition center and in conjunction with the plant cultivation plan. The planting module is equipped with a moving track arranged longitudinally along the planting space, dividing the planting space into several functional areas. When the plant, carrying the plant, moves between the functional areas of the planting space, resulting in the plant being located in different functional areas, the server controls the nutrient preparation center and the transmission and control center to execute one or more of the several planting modes.

[0010] To address the problem that most existing plant cultivation factories equipped with aeroponic technology use fixed, partitioned structures to form a three-dimensional planting structure, which cannot achieve structural space adjustment to adapt to the automation of processes such as cultivation, planting, harvesting, and cleaning, this application sets up corresponding control centers for functional structures such as lighting devices, aeroponic devices, and planting modules for supporting plants. These include a nutrient configuration center for configuring the nutrient solution required for each growth stage of the plant and controlling the aerosol parameters acting on the plant, and a transmission and control center for controlling the movement parameters of the planting module supporting the plant in the planting space. An information acquisition center is used to acquire plant status information and environmental information, enabling the plant cultivation factory's server to determine the plant cultivation plan based on pre-stored data and information from the information acquisition center.

[0011] To ensure the automation level of the plant cultivation factory at different stages such as planting and harvesting, intervention and cleaning, the planting space for arranging plants is divided into several functional areas along the direction of movement by the moving track carrying the plants. This allows the moving track carrying the plants to control the functional area where the plants are located and the movement parameters of the plants in each functional area according to the needs of different planting stages. This can significantly improve the ability of the vertical plant cultivation factory of this application to utilize light and mist conditions, and form an automated planting mode adapted to different planting stages by controlling each functional structure through the server.

[0012] Preferably, the nutrient preparation center is used to control the aerosol parameters of the aerosol unit. The aerosol unit is provided with a first nozzle for generating aerosol and a second nozzle for generating a jet, so that the aerosol unit can adjust the aerosol parameters by changing the activation ratio and spray parameters of the first and second nozzles.

[0013] The aerosol unit of the aerosol structure is used for aerosol culture of the plant root zone. The aerosol unit can be arranged in the lower half of the zone that contains the plant root zone. Considering that the plant root zone is prone to root adhesion during growth, the aerosol effect cannot rely solely on the mist nutrient solution to fully wet the plant root system. That is, it cannot overcome the phenomenon of the plant root system being moist on the outside but dry on the inside, resulting in insufficient contact between the mist nutrient solution and the plant root system to meet the plant's growth needs.

[0014] Therefore, the aerosol effect of this application possesses both the aerosol effect of mist and the jet effect of liquid flow. The aerosol effect and jet effect can be emitted through different nozzles and act on the plant roots simultaneously or intermittently. The ratio of aerosol and jet effects and the corresponding action parameters can be set according to the needs of the plant. For example, for plants with severe root adhesion, the jet effect ratio can be appropriately increased so that the plant roots can be dispersed under external force, providing conditions for sufficient aerosol wetting and contact. For plants with low adhesion, the jet can also improve the drooping state of the plant roots by stirring the roots, which can increase the contact time and area of ​​the internal roots with the aerosol. It can also promote the self-renewal of the plant roots through external force, eliminating old and weak roots and increasing root strength, thereby improving the plant roots' ability to absorb nutrient solution.

[0015] In addition, the mist and jet generated by the aerosol unit can act on the plant root zone from different directions and angles. Compared with the scheme of a single-direction mist or a mist unit moving around the plant root zone, the arrangement of the mist unit and connecting pipes in this application can significantly reduce the difficulty of arranging the mist unit and connecting pipes, and the angle at which the plant root zone receives the mist and jet is more diversified, which can significantly improve the efficiency of the plant root zone in absorbing mist.

[0016] Preferably, the planting space is arranged longitudinally with several functional zones, including a first zone for planting and harvesting and a second zone for aeroponic cultivation, allowing the planting module to move between the first and second zones with the plant carried by a moving track. With the plant arranged on the moving track of the planting module and the leaf and root zones positioned vertically on either side of the track, the planting space is divided by the moving track into an upper zone for accommodating the leaf zone and a lower zone for accommodating the root zone.

[0017] The longitudinally arranged moving tracks of the planting module can simultaneously serve as dividing structures for several functional areas. For example, the moving tracks, as dividing structures, can vertically divide the planting space into functional zones, such as an upper zone for accommodating plant leaves and a lower zone for accommodating plant roots. Alternatively, the planting space can be divided into several functional areas longitudinally according to the different arrangements of the moving track structures. These functional areas can be set up in conjunction with several operational processes such as the planting and harvesting process, the intervention process, and the cleaning process, so that the moving tracks located in different functional areas can arrange the plants carried on the moving tracks in a form suitable for the corresponding operational process.

[0018] Preferably, the server has a reset mode for the plant planting and harvesting processes. The transmission and control center controls the movement of the planting module's track to the first zone, enabling the planting module to perform planting, harvesting, or intervention operations using external equipment or manual operation. The server also has a cultivation mode for the plant aerosol culture process. When the plant is positioned in the second zone under the control of the transmission and control center, the nutrient configuration center adjusts the aerosol parameters of the aerosol unit to create several cultivation schemes suitable for different root zone distribution patterns. Finally, the server has a cleaning mode for the harvested planting module. When the planting module is positioned in the second zone under the control of the transmission and control center, the nutrient configuration center controls the aerosol parameters of the aerosol unit, causing the aerosol unit to generate a jet that acts on the planting module to clean the plant's tissue residue.

[0019] The server in this application is configured with corresponding planting modes for the plant planting and harvesting process, the plant cultivation process, and the cleaning process after harvesting, such as reset mode, cultivation mode, and cleaning mode. In different modes, the moving track carrying the plant moves the plant to the corresponding functional area under the control of the transmission control center to complete the corresponding operation process. For example, in reset mode, the moving track moves the plant to the first zone for planting and harvesting. The moving track in the first zone is set to a flat structure instead of the undulating structure used for implementing aeroponic cultivation to obtain the second zone, allowing external equipment or personnel to perform planting, harvesting, or intervention operations on the moving track located in the first zone. By periodically configuring the planting modes corresponding to the above processes, this application can complete the automated crop planting process through a plant factory with several planting modes.

[0020] Preferably, when the moving track of the planting module is provided with a second zone for arranging plants and a transition zone for connecting adjacent cultivation zones, the transition zone is connected to the frame in a way that it can rotate relative to the moving track. The transition zone is movably connected to the cultivation zone, so that the two ends of the transition zone are separated from the cultivation zone during rotation and form a clean channel connecting the upper and lower half of the planting space.

[0021] The transition zone, biased towards the lower half of the planting space, deflects the jet stream, allowing it to act on the upper surface of the cultivation area. The transition zone, biased towards the upper half of the planting space, receives the jet stream and tissue residue acting on the upper surface of the cultivation area and directs it to the lower half of the planting space. For the cleaning process after harvest, a downstream aeroponic device can be used. Because the moving track divides the planting space into an upper half for accommodating plant leaves and a lower half for accommodating plant roots, the aerosol and jet stream from the aeroponic device have difficulty acting on the upper half. Therefore, the moving track can be equipped with an adjustable structure to form a cleaning channel connecting the upper and lower halves during the cleaning process. Especially after the crop is harvested and removed, some plant tissue debris may adhere to the surface of the moving track near the upper half, preventing the jet stream emitted by the aeroponic device in the lower half from directly cleaning, or preventing the aerosol and jet stream entering the upper half from the planting holes from effectively returning to the lower half. Based on this, the application can use the transition zone on the moving track as the location for arranging the cleaning channel. The transition zone rotates at a certain angle relative to the cultivation zone to form a baffle that can be used to change the direction of the jet. Then, the jet generated from the lower half of the zone can be deflected by the baffle and flush the cultivation zone adjacent to the baffle. The jet acting on the upper surface of the cultivation zone cleans the tissue residue of the plant and flows from the planting hole of the cultivation zone to the lower half of the planting space.

[0022] Preferably, the moving track of the planting module includes several rotating shafts positioned at a first height and a second height in the planting space, such that a frame connecting the rotating shafts forms an undulating track extending longitudinally towards the planting space. The frame is provided with a stationary part for connecting the rotating shafts and a movable part for supporting the plants. When the rotating shafts are connected to a power device, the rotating shafts can drive the movable part of the frame to move in a wave-like motion relative to the stationary part along the undulating track. The moving track of the planting module can form first and second planting units facing the upper and lower halves of the planting space respectively, such that the moving track is composed of several first planting units or several second planting units.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] This application proposes a three-dimensional plant cultivation factory. This plant cultivation factory applies aeroponic technology to a vertical cultivation structure to overcome the problem that most existing cultivation structures use fixed, partitioned structures, resulting in plants not fully utilizing light diffusion and mist diffusion. This application sets the fixed partitioned structure as a movable, adjustable conveyor structure, allowing the movable conveyor structure to carry the plants relative to the lighting unit 201 or the aeroponic device, ensuring the uniformity of light, mist, and other nutrient conditions received by the plants. Furthermore, the movable conveyor structure not only divides the planting module 500 into several independent functional spaces, but also allows for changes in the connection state of each functional area at different planting stages, such as during planting, harvesting, or cleaning. The conveyor structure can work in conjunction with the aeroponic device and lighting structure to meet the functional needs of the plants in the planting module 500 at each stage.

[0031] like Figure 1As shown, to achieve automated planting in the plant cultivation factory, the plant cultivation factory has a transmission control center 603 for the transmission structure used to move the plants, enabling the transmission control center to control the movement parameters of the transmission structure; a light management center 602 for the lighting structure used to provide light sources, enabling the light management center 602 to provide the light conditions required for different planting stages for the plants; a nutrient configuration center 601 for the aeroponic device used for aeroponic planting, enabling the nutrient configuration center 601 to provide the aerosol conditions for different planting stages for the plants; the plant cultivation factory also has an information acquisition center 604 for collecting plant status information and environmental information, enabling the plant cultivation factory's server 600 to obtain planting plans based on the information obtained by the information acquisition center 604 to guide the transmission control center 603, the light management center 602, and the nutrient configuration center 601.

[0032] Regarding the structural setup of plant cultivation factories, such as Figure 2 As shown, to effectively improve the space utilization rate under the factory-style planting mode, the planting module 500 for the plant cultivation factory in this application has a planting space 100 in the middle of the space for arranging plants and plant load structures. The planting space 100 can be set as a rectangular space with vertical, longitudinal, and transverse directions according to the needs of plant arrangement and activities. The vertical direction is the height direction of the planting space 100, the longitudinal direction is the length direction of the planting space 100, and the transverse direction is the width direction of the planting space 100. The planting space 100 has an upper space 200 on the side near the plant leaf area and a lower space 300 on the side near the plant root area. That is, the upper space 200 and the lower space 300 are placed on the vertical sides of the planting space 100. According to the arrangement direction of the plants in the planting space 100, the upper space 200 can be used to arrange the lighting unit 201, so that the lighting unit 201 can cover the leaf area of ​​the plant and provide light conditions for different growth stages of the plant by adjusting the parameters of the lighting unit 201. The upper space 200 can also accommodate sensing units 202 for monitoring plant growth, taking advantage of its field of vision. These sensing units 202 can collect image information, temperature information, air parameters, etc., to provide feedback on plant growth and environmental conditions. The lower space 300 is used to house aerosol cultivation devices, enabling these devices in the planting space 100 to output the necessary mist for the plant's current growth stage, acting on the root zone. The lower space 300 can also accommodate corresponding recycling and cleaning devices, which can clean up plant debris that falls to the bottom of the planting space 100 and recover the nutrient solution for reprocessing. Therefore, the upper space 200 can be considered the functional area for accommodating plant leaves (the upper half), and the lower space 300 can be considered the functional area for accommodating plant roots (the lower half).

[0033] like Figure 2and Figure 3 As shown, a planting module 500 capable of supporting and moving plants is arranged within the planting space 100. The planting module 500 can move the plants along at least one direction (longitudinal, transverse, and vertical) of the planting space 100 via a moving structure. This allows the plants to undergo a combination of linear and circumferential motion relative to the lighting device and the aeroponic device. Under this combined motion, the plants can obtain more uniform nutrient conditions by utilizing changes in the angles of light and mist. Specifically, the planting module 500 is equipped with a moving track 501 for supporting the plants. The moving track 501 includes a rotating shaft 5011 and a frame 5012 arranged on the rotating shaft 5011. The frame 5012 has a stationary part that is stationary relative to the planting space 100 and a movable part that moves relative to the planting space 100. This allows the stationary part of the frame 5012 to support the movable part, which carries the plants, and to move relative to the stationary part. The planting space 100 has several rotating shafts 5011 extending laterally along the first and second heights, respectively. These rotating shafts 5011 support the stationary portion of the frame 5012, forming an undulating track foundation. Driven by a power device, some of the rotating shafts 5011 connected to the power device transmit force to the moving portion, driving the moving portion of the frame 5012 to move relative to the stationary portion along the track foundation formed by the stationary portion. The remaining shafts not connected to the power device act as driven shafts, allowing the rotating shafts 5011 and the frame 5012 to form a combined structure that supports the plants and allows for undulating movement along a moving track 501. Figure 4 As shown, to ensure the functional stability of the power device driving the moving track 501, the power device is arranged in the transmission space 400, which is distributed on both sides of the planting space 100, so that the power device can at least be connected to a portion of the rotating shaft 5011 of the moving track 501 to provide power to drive the moving track 501 to move. The power device can be a mechanical device driven by electricity or chemical fuel, such as a combination of an electric motor and a gearbox to form a power device that can control the motion parameters of the moving track 501. Since the tissue residue or waste generated during the plant growth stage will accumulate at the bottom of the planting space 100, and the condensed and dripping nutrient solution further aggravates the viscosity and humidity of the waste at the bottom of the planting space 100, if it is not cleaned in time, it will cause environmental deterioration of the planting space 100. Therefore, this application provides a cleaning unit 401 for cleaning tissue residue and waste at the bottom of the planting space 100. The cleaning unit 401 moves back and forth along the longitudinal direction of the planting space 100 by a track arranged along the side of the planting space 100. The cleaning unit 401 is driven by a power device arranged in the transmission space 400, so that the cleaning unit 401 can carry cleaning tools such as brushes and rags to clean the bottom of the planting space 100, avoiding the accumulation of tissue residue and waste.

[0034] like Figure 2 and Figure 3 As shown, to achieve effective spatial division of the planting space 100 by the planting module 500 of this application, the planting space 100 is divided longitudinally into a first zone 101, a second zone 102, and a third zone 103 according to the functional zoning of the planting module 500. The first zone 101, located at one end of the longitudinal direction of the planting space 100, mainly functions during the planting or harvesting process of the planting module 500. Compared to stacked, fixed multi-layer planting modules 500, the planting module 500 of this application, with its arrangement of moving plants via a moving track 501, allows for dynamic adjustment of plant planting and harvesting, avoiding the need for disassembly and assembly of the planting module 500. The third zone 103, located at the other end of the planting space 103, primarily serves as a third zone 103 for adaptive adjustment of the moving track 501, allowing the third zone 103 to expand the range of plant movement during maintenance or adjustment of motion parameters. The second zone 102, located between the first zone 101 and the third zone 103, serves as the main space for aeroponic cultivation of plants. The plants move back and forth relative to the lighting unit 201 and the misting unit 303 by means of the undulating moving track 501, thereby simulating the process of plants receiving light and mist from all directions to ensure the uniformity of nutrient conditions received by the plants.

[0035] Specifically, the moving track 501 arranged in the first zone 101 can be arranged with a straight section and an inclined section. The moving track 501 in the first zone 101 includes a pivot 5011 and a stationary part of the frame 5012, so that the movable part of the frame 5012 carrying the plant can move from the inclined section to the straight section along the moving track 501 in the first zone 101. The second zone 102 is composed of several pivots 5011 and several inclined sections, so that the planting module 500 in the second zone 102 forms several first planting units 504 opening towards the upper space 200 and second planting units 505 opening towards the lower space 300, respectively. The moving track 501 in the third zone 103 includes an inclined section, which is provided with a pivot 5011 and a stationary part of the frame 5012, so that the movable part of the frame 5012 carrying the plant can move from the second zone 102 to the inclined section of the third zone 103 to expand the range of motion of the moving track 501 in the second zone 102. The first zone 101 and the second zone 102 form an interconnected structure, allowing plants to be moved from the second zone 102 to the first zone 101 for planting or harvesting during the harvesting or planting stage. The first zone 101 can be connected to external machinery, which can transport the configured plant seedlings or seeds along the moving track 501 of the first zone 101 to the moving track 501 of the second zone 102. External machinery can also be used to receive the plants transported from the second zone 102 to the first zone 101 via the moving track 501 for harvesting or chemical treatment. This allows for the batch planting and harvesting of plants by adjusting the moving track 501 in different functional areas of the planting space 100, avoiding the increased workload and labor costs of disassembling and assembling the planting space 100. Based on the automation of planting, the planting efficiency of the planting module 500 of this application can be significantly improved.

[0036] Preferably, to ensure that the moving track 501 can adapt to horizontal and inclined movements, the structure arranged in the movable part of the frame 5012 of the moving track 501 is provided with a cultivation area 502 for arranging plants and spaced apart, and a transition area 503 arranged between adjacent cultivation areas 502. During the process of the plants moving with the moving track 501, the arrangement surface of the cultivation area 502 carrying the plants remains horizontal. To ensure that the cultivation area 502 can adapt to inclined and horizontal movements, the arrangement surface of the transition area 503 remains horizontal in the horizontal section, while the arrangement surface of the transition area 503 remains vertical in the inclined section. This makes the cultivation area 502 and the transition area 503 form a stepped structure in the inclined section, and places the leaf area and root area of ​​the plant on both sides of the stepped structure in the vertical direction, facing the upper space 200 and the lower space 300 respectively. Both the culture area 502 and the transition area 503 can be disassembled and assembled relative to the frame 5012 of the moving track 501. For example, the culture area 502 and the transition area 503 are snapped into several rectangular frames 5012 formed by the movable part of the frame 5012. The adjacent rectangular frames 5012 are connected by hinges, so that the adjacent rectangular frames 5012 can rotate relative to each other and cause the culture area 502 and the transition area 503 to change relative angles. Then the movable part of the load culture area 502 and the transition area 503 can adapt to the movement of the moving track 501 between the inclined section and the horizontal section. In the inclined section, the transition zone 503 ensures effective connection of the cultivation zones 502 to form a continuous structure supporting plant movement. However, a single cultivation zone 502 would cause its arrangement to follow the inclined section, resulting in skewed plant placement and affecting normal plant growth. This is especially problematic for varieties with weak rootstocks, where skewed placement can lead to rootstock bending and deformities, impacting plant morphology and production efficiency. In the horizontal section, the transition zone 503 serves as an intervening operating space between the cultivation zones 502. Particularly during planting and harvesting in the first zone 101, the transition zone 503 provides space for the interaction between automatic seeding or harvesting equipment and the cultivation zone 502, preventing damage to plant quality and improving operational efficiency.

[0037] like Figure 3 and Figure 4As shown, to achieve effective spatial division of the planting space 100 by the planting module 500 according to the plant arrangement characteristics, the planting module 500, which is undulating between the first and second vertical heights of the planting space 100, divides the planting space 100 into an upper half containing the plant leaf area and a lower half containing the plant root area via a moving track 501. For the moving track 501 located in the second area 102, the frame 5012 is connected to adjacent rotating shafts 5011 to form a moving track 501 composed of several V-shaped first planting units 504 or several inverted V-shaped second planting units 505. For the V-shaped first planting unit 504, its opening direction faces the upper space 200, and for the inverted V-shaped second planting unit 505, its opening direction faces the lower space 300. As the plant moves back and forth in the second zone 102 of the planting space 100 following the moving track 501, the area in which the plant moves back and forth along the moving track 501 is one or more first planting units 504 or second planting units 505. That is, the plant located at the edge of the moving track 501 moves along one or more V-shaped structures on one longitudinal side of the moving track 501, and then moves to the other longitudinal side of the moving track 501 with the same number of V-shaped structures, so that the plant moves back and forth within the moving track 501 corresponding to several first planting units 504 or second planting units 505.

[0038] Preferably, to fully utilize the longitudinal space of the second zone 102, the range of the plant's reciprocating movement is the range of the moving track 501 corresponding to a single first planting unit 504. Therefore, during the reciprocating movement, redundant spaces within the track range corresponding to a single first planting unit 504 alternately exist on both sides of the longitudinal direction of the second zone 102 to serve as the activity range for the plant's reciprocating movement in the second zone 102. For a plant at a specific location, during one reciprocating movement following the moving track 501, the leaf and root areas of the plant travel along the moving track 501 within the reciprocating range of a single first planting unit 504 or the second corresponding unit, causing the leaf and root areas of the plant to undergo a combination of linear and circumferential movements relative to the upper space 200 and lower space 300, respectively.

[0039] Preferably, for the leaf area of ​​the plant, the upper space 200 corresponds to the first planting unit 504 of the planting module 500, and the corresponding lighting unit 201 is arranged. The lighting unit 201 extends vertically along the planting space 100 to form a light-emitting structure arranged on the central axis of the first planting unit 504. In the horizontal direction of the planting space 100, a number of lighting units 201 are arranged side by side to form an array of lighting units 201 arranged in the horizontal direction to cover the range of the first planting unit 504 extending in the horizontal direction. During the reciprocating movement of the plant, the plant located at the end of the first planting unit 504 descends and then rises along the V-shaped moving track 501, causing the plant to move linearly along the planting space 100 and rotate relative to the lighting unit 201 corresponding to the first planting unit 504. The plant serves as the main illumination surface of the lighting unit 201 on both sides in the longitudinal direction to simulate the rotational illumination process of the sun relative to the plant in its natural state. Compared with the prior art scheme in which the lighting unit 201 moves around the plant, this application treats the lighting unit 201 as a stationary structure, which can reduce the complexity of the circuit layout of the lighting unit 201 and avoid the instability factors of the lighting unit 201 during the moving illumination process. This allows the planting of this application to effectively simulate natural sunlight, while ensuring the applicability and stability of the lighting function through the functional zoning and the stationary setting of the lighting unit 201. Meanwhile, the vertically extending structure of the lighting unit 201 reduces the variation in light distance caused by plant movement to different positions of the first planting unit 504. The luminous intensity of the lighting unit 201 at corresponding angles towards different positions of the first planting unit 504 can also be correlated with the direct illumination distance to improve the uniformity of illumination at different distances, or to ensure a regular variation in the intensity of light received at different positions of the first planting unit 504. For example, the luminous intensity at a corresponding angle of the lighting unit 201 is proportional to the illumination distance at that location, ensuring that the light intensity received at different positions of the first planting unit 504 remains consistent.

[0040] Preferably, for the root zone of the plant, the lower space 300 is correspondingly provided with a functional container and a spraying device for realizing aeroponics. The lower space 300 includes a configuration unit 301 for preparing nutrient solution and a recovery unit 302 arranged at both ends of the configuration unit 301 for recovering the aerosol from the planting space 100. The recovery unit 302 can separate the tissue waste and nutrient solution gathered by the cleaning unit 401, so as to obtain solid waste that can be used for composting and nutrient solution for recycling. The recovered nutrient solution is recycled back into the configuration unit 301 after being filtered and impurity removed. The nutrient solution of the configuration unit 301 is transported through a pipeline to the aerosol unit 303 located in the lower half of the planting space 100, so that the aerosol unit 303 can cooperate with the moving track 501 to provide aerosol and jet with varying angles of action to the root zone of the plant. For example, the misting unit 303 is configured to correspond to the second planting unit 505 of the planting module 500, so that several misting units 303 arranged laterally along the planting space 100 can be placed in the inverted V-shaped space of the second planting unit 505. The misting unit 303 is connected to the configuration unit 301 located in the lower space 300 through pipes, so that the misting unit 303 can provide mist and jets to the root zone of the plants in the second planting unit 505 through the misting generating structure. During the reciprocating movement of the root zone of the plants in the second planting unit 505 following the moving track 501, the misting unit 303 can simultaneously or selectively provide mist and jets to the root system of the plants in the second planting unit 505, so that the direction of the mist and jets can at least cover the spatial range of the second planting unit 505 relative to the misting unit 303. To fully utilize the diffusion characteristics of the aerosol, the aerosol unit 303 is provided with several nozzles laterally along the planting space 100, such that the nozzles are arranged at intervals laterally in a manner that allows the aerosol to be sprayed radially along the aerosol unit 303. For example, the aerosol unit 303 has several sets of nozzles arranged laterally, with each set of nozzles arranged around the circumference of the aerosol unit 303, so that the emission direction of each set of nozzles can cover the spatial range of the second planting unit 505 relative to the aerosol unit 303. Adjacent sets of nozzles are staggered around the aerosol unit 303, so that the aerosol and jet from the several sets of nozzles arranged laterally can form a spiral spray around the aerosol unit 303 to fully cover the root zone of the plant extending laterally in the second planting unit 505.

[0041] To improve the coverage efficiency of the mist and jet provided by the aerosol unit 303 on the plant root zone, the mist and jet emitted from each set of nozzles of the aerosol unit 303 diffuse along the emission direction and, through the combined action of multiple sets of nozzles, cover the lateral range of the second planting unit 505 corresponding to the range of the aerosol unit 303 containing that set of nozzles. This avoids the cross-coverage effect of adjacent nozzles in the lateral direction, which could cause excessively high local mist concentrations in the plant root zone. Furthermore, the number of aerosol units 303 arranged laterally can be controlled by adjusting the nozzle diffusion level, thereby providing precisely controlled nutrient conditions to the root zone. To improve the contact efficiency between the mist and jet provided by the aerosol unit 303 and the plant root zone, it is necessary to use external interference to disperse the plant root zone, thereby increasing the contact area between the plant root zone and the mist and preventing the plant root zone from becoming excessively wet on the outside and dry on the inside. Specifically, the nozzle of the aerosol unit 303 includes a first nozzle for generating aerosol and a second nozzle for generating jet. The first nozzle and the second nozzle are arranged at intervals in each group of nozzles in the aerosol unit 303, so that the aerosol generated by the first nozzle can provide sufficient nutrition to the plant root zone, while the jet generated by the second nozzle can disperse the plant root zone by external force, thereby expanding the contact area between the plant root zone and the aerosol and improving the phenomenon of knotting and entanglement in the plant root zone.

[0042] During the reciprocating motion of the plants in the second planting unit 505 following the moving track 501, the root zone of the plants remains horizontal, and under the action of gravity, it maintains a drooping distribution towards the lower space 300. As the root zone of the plants moves from one end of the second planting unit 505 to the other along the moving track 501, the areas on both sides of the plant root zone alternately receive the mist and jet generated by the mist unit 303. This allows the mist and jet generated by the mist unit 303 to act on the plant root zone from different directions and angles. Compared with a single-direction mist or a mist unit 303 moving around the plant root zone, the arrangement of this application can significantly reduce the difficulty of arranging the mist unit 303 and connecting pipes, and the angle at which the plant root zone receives the mist and jet is more diversified, which can significantly improve the efficiency of the plant root zone in absorbing mist and improve the drooping state of the plant root zone.

[0043] Preferably, when the plants on the moving track 501 of the planting module 500 are subjected to undulating reciprocating motion for aeroponics, the lighting unit 201 and the misting unit 303 provide different light and mist parameters to the first planting unit 504 and the second planting unit 505 based on the angular range of the first planting unit 504 and the second planting unit 505 relative to the lighting unit 201 and the misting unit 303. The light parameters include light intensity, spectral structure, and light cycle; the mist parameters include spray flow rate, spray speed, spray frequency, and the ratio of mist to jet. That is, the action mode of the lighting unit 201 and the misting unit 303 on the plant leaf area and the plant root area is set according to the angular changes of the plant leaf area relative to the lighting unit 201 and the plant root area relative to the misting unit 303.

[0044] For the leaf area of ​​the plant in the first planting unit 504, the angle range of the leaf area of ​​the plant in the first planting unit 504 relative to the lighting unit 201 is divided into several sub-ranges and several range nodes. For example, when the lower end height of the lighting unit 201 is the same as the height of the upper rotating shaft 5011, the angle range of the plant in the first planting unit 504 relative to the lighting unit 201 is 180 degrees; when the lower end height of the lighting unit 201 is between the upper rotating shaft 5011 and the lower rotating shaft 5011, the angle range of the plant in the first planting unit 504 relative to the lighting unit 201 is between 180 degrees and 360 degrees. The lighting unit 201 can move vertically relative to the first planting unit 504, so that the height of the lighting unit 201 can be adjusted according to the growth stage or variety of the plant. When the plant is in the seedling stage, the lighting unit 201 is lower in height to reduce the distance between the lighting unit 201 and the plant. The light distance can be adjusted to provide sufficient light to the plant and maintain a low energy consumption level. When the plant is taller, the lighting unit 201 is taller to adapt to the change in illumination distance caused by the increase in the height of the plant's canopy.

[0045] To enhance the targeted illumination of plants by the lighting unit 201, the angle of the plant leaf area relative to the lighting unit 201 is divided into at least a first illumination range, a second illumination range, and a third illumination range. The lighting unit 201 adopts different light intensities and / or spectral structures for the first to third illumination ranges, so that the first to third illumination ranges can provide targeted side illumination or top canopy illumination for different plant varieties. For example, when the angle range is 0-180 degrees, the first irradiation range is 0-80 degrees, the second irradiation range is 80-100 degrees, and the third irradiation range is 100-180 degrees. The first and third irradiation ranges are mainly for plants located on the side of the first planting unit, where the plant receives mainly side and top light. The second irradiation range is mainly for plants located at the bottom of the first planting unit, where the plant receives mainly top light. For plants primarily cultivating leaf crowns, the lighting unit 201 sets corresponding light intensities and spectral structures in the first and third irradiation ranges to promote the expansion of the plant's leaf crown and provides a spectral structure that inhibits apical dominance in the second irradiation range. For plants primarily cultivating stems, the lighting unit 201 sets corresponding light intensities and spectral structures in the first and third irradiation ranges to promote the elongation of the plant's stem and provides a spectral structure that stimulates apical dominance in the second irradiation range. The light intensity and spectral structure of the first to third irradiation ranges are then set specifically according to the plant production stage and plant cultivation goals to improve the effective yield of the target parts of the plant.

[0046] For the root zone of the plants in the second planting unit 505, to improve the effect of the aerosol unit 303 on the root zones at different relative angles or at continuous operating distances, the nozzles of the aerosol unit 303 are equipped with different aerosol parameters for the root zones at different angles. These aerosol parameters may include spray flow rate, spray speed, spray frequency, and aerosol to jet ratio. To reduce the deviation in the operating distance of the aerosol unit 303 on the root zones within the second planting unit 505, the aerosol unit 505 is positioned between the upper and lower rotating shafts 5011, for example, at a position between 1 / 3 and 1 / 2 of the height interval between the upper and lower rotating shafts 5011. To enhance the effect of the aerosol unit 303 on the root zones, the angle range of the root zone of the second planting unit 505 relative to the aerosol unit 303 is divided into several sub-ranges, and the aerosol parameters of the nozzles acting on these sub-ranges are specifically set. For example, the angle between the plant root zone of the second planting unit 505 and the aerosol unit 303 ranges from -45 to 225 degrees. The range of -45 to 0 degrees is defined as the first effective range, 0 to 45 degrees and 135 to 180 degrees as the second effective range, 45 to 135 degrees as the third effective range, and 180 to 225 degrees as the fourth effective range. For the first and fourth effective ranges, the plant root zone is farther from the aerosol unit, and the direction of action forms an acute angle with the downward direction of the root zone. Therefore, the nozzles of the aerosol unit 303 corresponding to the first and fourth effective ranges need to have their aerosol parameters adjusted, for example, by increasing the spray flow rate and spray speed. For the second effective range, where the plant root zone is relatively close and the direction of action is at an obtuse angle to the downward direction of the plant root zone, the aerosol unit 303 adjusts the aerosol parameters corresponding to the nozzle of the second range. For example, it can reduce the spray flow rate and spray speed to increase the proportion of aerosol action and avoid damage to the plant root zone from direct jet action at close range. For the third effective range, where the plant root zone is relatively far away and the direction of action is at an obtuse angle to the downward direction of the plant root zone, the aerosol unit 303 can adjust the aerosol parameters corresponding to the nozzle of the third range to obtain the action angle from the bottom of the plant root zone, which can effectively improve the problem of uneven moisture or dryness in the plant root zone.

[0047] Preferably, the sensing unit 202, located in the planting space 100, obtains characteristic image information about the abnormal state of the plant using plant images. The compensator, also located in the planting space 100, moves to the spatial position corresponding to the characteristic image information by cruising or triggering movement within at least a portion of the planting space 100, enabling the compensator to provide compensation or intervention for the plant corresponding to the characteristic image information. The compensator can move back and forth along the longitudinal direction of the planting space 100, allowing it to function as a light supplement or mist supplement device to compensate for the blind spots in illumination or misting caused by the fixed lighting unit 201 and misting unit 303, such as the leaf and root areas of the plant loaded by the moving track 501 located at the pivot 5011. Illumination blind spots or fogging blind spots often lead to abnormal plant morphology or localized lesions. Fixed lighting and fogging units are insufficient to provide targeted compensation or intervention. Compensation can include providing additional light or nutrient solution fogging, while intervention involves adding corresponding light to treat lesions or adding substances to treat lesions to the nutrient solution fogging. The sensing unit 202 of the cultivation bed can be set in the upper and lower halves of the planting space 100 to monitor plant status. It can obtain the special status of plants in local locations based on image information, such as abnormal plant color or pathological features, and identify them as image feature information. To reduce the workload of intervention operations performed on plants in the first zone 101, the compensator can provide corresponding compensation or intervention for the leaf or root areas of plants in local locations through the lighting and fogging devices to overcome uneven nutrition or lesions. The compensator can achieve flexible compensation for the leaf and root areas of plants in local locations of the planting module 500 through various movement modes of the planting space 100. Specifically, the compensator has a first movement mode in the planting space 100. In the first movement mode, the compensator cruises within the planting space 100, so that the movement range of the compensator can at least cover the second zone 102 of the cultivation space 100 used for aeroponics. The frequency of the cruise movement of the compensator can be set, so that the compensator can move periodically in the planting space 100 and perform compensation or intervention on the local plant leaf area and plant root area of ​​the second zone 102 according to the image feature information of the sensing unit 202 and the information interaction between the sensing unit 202 and the compensator. This movement mode can fully cover the planting module through cruise movement, and can move to the position that needs to be treated in a timely and accurate manner according to the feature image information of the sensing unit. It can periodically provide compensation for dead corner positions, and can also treat diseased plants in a timely manner to control the spread of disease.The compensator has a second movement mode for moving within the planting space. In this mode, the compensator can be configured to move based on image information from the sensing unit 202. When the sensing unit 202 obtains image feature information of the plant's leaf or root area, including morphological or disease characteristics, the compensator can obtain the specific location requiring compensation or intervention through information interaction with the sensing unit 202. This allows the compensator to move from its initial position to the location corresponding to the image feature information and perform compensation or intervention on the plant's root or leaf area. This mode enables the compensator to move in a targeted manner through triggering, avoiding unnecessary energy consumption during cruise movement and reducing structural wear to extend its service life. Preferably, to improve the utilization efficiency of nutrient solution in the plant's root area, the connecting surface and the planting surface facing the lower space 300 are provided with a textured structure that can collect aerosol condensation droplets in the plant's root area. For the inclined section of the planting module 500, the transition zone 503 is in a vertical state while the cultivation zone 502 is in a horizontal state. The first groove in the transition zone 503 is arranged vertically, so that the droplets condensed in the transition zone 503 can flow to the cultivation zone 502 along the vertically arranged first groove. The second groove in the cultivation zone 502 is arranged in a way that converges towards the center of the plant root zone in a local area around the plant root zone. The cultivation zone 502 where the plant root zone is located is the lowest point in the local area, so that the droplets condensed in the local area of ​​the planting surface and some droplets collected by the connecting surface can converge to the cultivation zone 502 where the plant root zone is located to moisten the plant root zone. The droplets contact or drip onto the plant root zone under the action of gravity, thereby improving the utilization efficiency of the nutrient solution in the plant root zone and avoiding the waste of nutrient solution caused by the condensed droplets dripping directly onto the bottom of the planting space 100.

[0048] Preferably, such as Figure 1As shown, this application provides control centers for regulating each major functional structure. Each control center is connected to the server 600 of the plant cultivation factory to achieve data exchange. For example, the nutrient configuration center 601 controls the configuration unit 301 and the aerosol unit 303, ensuring that the nutrient solution parameters input to the aerosol unit 303 meet the growth needs of the plant at the current cultivation stage and that aerosols are sprayed according to a set plan or scheme. The nutrient configuration center 601 is connected to the server 600, allowing the plant cultivation plan, plant status information, and environmental information obtained through the server 600 to provide guidance on configuring nutrient solution parameters, including the concentration, flow rate, and temperature of each nutrient component. The light management center 602 controls the lighting unit 201, ensuring that the lighting parameters illuminating the plant's leaf area meet the plant's growth needs at its current cultivation stage. The light management center 602 is connected to the server 600, allowing the server to provide guidance on configuring lighting parameters based on plant cultivation plans, plant status information, and environmental information. These lighting parameters include the luminous intensity time curve, spectral structure, and vertical distribution of luminous intensity for each lighting unit. The transmission control center 603 controls the moving track 501, ensuring that its motion parameters meet the plant's growth needs at its current cultivation stage. The transmission control center 603 is also connected to the server 600, allowing the server to provide guidance on configuring motion parameters based on plant cultivation plans, plant status information, and environmental information. These motion parameters include reciprocating motion cycles and speed. The information acquisition center 604 collects plant status and environmental information and provides it to the server 600. For example... The information acquisition center 604 is connected to the first sensing unit 202 located in the upper space 200, so that the sensing unit 202 can transmit plant images and plant morphological parameters representing plant status information, as well as air humidity, mist density and air temperature representing environmental information to the information acquisition center 604. The information acquisition center 604 can also arrange a second sensing unit 202 on the longitudinal side of the planting space 100 for monitoring the plant root zone and the lower half of the planting space 100, so that the information acquisition unit can acquire plant status information including the plant root zone and the plant leaf zone, as well as environmental information including the upper half and the lower half of the planting space 100.

[0049] Preferably, in order to improve the functional applicability of the planting module 500 in the harvesting, planting and cleaning processes, the server 600 is equipped with several planting modes that are applicable to different growth cycles or growth states of the plants.

[0050] Preferably, the server 600 has a reset mode for the plant sowing and harvesting process. The nutrient configuration center 601 reduces the concentration and flow rate of nutrients in the nutrient solution, allowing the aerosol generated by the aerosol unit 303 to maintain plant moisture and surface condition. The light management center 602 reduces the luminous intensity of the lighting unit, allowing the light emitted by the lighting unit to provide ambient light to assist the sensing unit 202 in obtaining its sensing field of view. The information acquisition center 604 acquires plant status information and environmental information to ensure normal transport of plants during harvesting and planting. The transmission control unit... The reciprocating motion of the plant-loaded track 501 can be adjusted so that it can be transferred from the second zone 102 of the planting space 100 to the first zone 101 or external equipment, or the plant-loaded track 501 can be transferred from the first zone 101 of the planting space 100 or external equipment to the second zone 102 of the planting space 100. This enables automatic transfer and operation of the plant during the planting and harvesting process. Only a small amount of manual operation of the external equipment is required to realize the planting and harvesting of the plant, avoiding the increased workload caused by disassembling the planting module and the resulting damage to the plant quality and yield loss.

[0051] Preferably, the server 600 has a cultivation mode set for the cultivation process of plants in the second zone 102 of the planting space 100. The nutrient configuration center 601 and the light management center 602 determine the nutrient solution parameters and lighting parameters through the server 600, so that the nutrient solution parameters and lighting parameters are suitable for the current plant. The uniformity of the aerosol and light received by the plant is ensured by the plant reciprocating on the moving track 501. In order to improve the automatic adjustment capability of the planting module 500 during the cultivation process, the cultivation mode of the server 600 includes several cultivation schemes for different cultivation states of the plant. Under different cultivation schemes, the aerosol parameters of the aerosol unit 303 are different. The aerosol parameters include: the activation ratio of the first nozzle and the second nozzle, the spray parameters of the first nozzle and the second nozzle, etc., so that the aerosol unit 303 can effectively improve the problem of the plant root zone being wet outside and dry inside, as well as the problem of tangling and overlapping. For example, in the case where the plant reciprocates on the moving track 501 and the root zone morphology is normal, the cultivation mode has a first scheme where the aerosol unit 303 uses several first nozzles to operate, so that the first nozzles spaced circumferentially on the aerosol unit 303 can provide the corresponding aerosol conditions to the root zone of the second planting unit 505. In the case where the plant reciprocates on the moving track 501 and the root zone partially overlaps and becomes entangled, the cultivation mode has a second scheme where the aerosol unit 303 uses several first nozzles and several second nozzles to operate in combination. The first nozzles are used to generate aerosol from the nutrient solution, while the second nozzles are used to generate jets. The jets can use ordinary water sources different from the nutrient solution, allowing the jets to disturb the plant root zone with external force, increasing the degree of root spread and thus reducing the probability of root knots and entanglements. The first and second schemes can also be used alternately, so that the aerosol unit 303 can periodically use the second scheme or activate the second scheme according to the condition of the plant root zone to improve the drooping state of the plant root zone.

[0052] Preferably, to enhance the automatic adjustment capability of the planting module 500 during the cleaning process, the server 600 sets a cleaning mode for the harvested planting module 500. The cleaning mode is used to process the moving track 501 and load structure after harvesting, thereby preparing for the next planting. In the cleaning mode, the transition zone 503 of the planting module 500 can be adjusted relative to the cultivation zone 502, so that the transition zone 503 is disconnected from at least one of the two adjacent cultivation zones 502 and rotates to form a set angle relative to the cultivation zone 502, which can form a cleaning channel connecting the lower half and the upper half of the planting space 100. The aerosol unit 303 activates several second nozzles, so that the jet generated by the second nozzles can be transferred from the lower half to the upper half of the planting space 100 through the cleaning channel and clean the surface of the cultivation zone 502. To ensure that the jet does not directly affect the lighting unit 201 and sensing unit 202 in the upper half of the planting space 100, the lighting unit 201 and sensing unit 202 are equipped with transparent protective covers to prevent mist and jet from contacting the equipment in the upper space 200. In addition, the set angle of the transition zone 503 relative to the cultivation zone 502 not only prevents the jet from interfering with the equipment in the upper space 200, but also enhances the cleaning ability of the jet on the cultivation zone 502. Specifically, for the inclined section of the planting module 500, the transition zone 503 rotates relative to the cultivation zone 502 at its lower end toward the upper half of the planting space 100, so that the transition zone 503, which was originally in a vertical state, becomes in an inclined state. For example, the angle between the transition zone 503 and the cultivation zone 502 is 60 degrees, so that the jet emitted by the aerosol unit 303 and acting on the transition zone 503 is transmitted to the surface of the cultivation zone 502 under the guidance of the angle of the transition zone 503. The jet acting on the upper surface of the cultivation zone 502 cleans the tissue residue of the plant and flows from the planting hole of the cultivation zone 502 to the lower half of the planting space 100.

[0053] Preferably, to ensure the smooth flow of the jet acting on the upper surface of the culture area 502 and to make full use of the inclined state of the inclined section, the transition area 503 is connected to the frame 5012 in a manner that allows it to rotate relative to the axis on the frame 5012. The transition area 503 and the culture area 502 are movably overlapped, so that the two ends of the transition area 503 disengage from the culture area 502 during rotation and form a clean channel connecting the upper and lower halves of the planting space 100. The surface of the transition area 503 biased towards the lower half of the planting space 100 is used to deflect the jet direction to act on the upper surface of the culture area 502, and the surface of the transition area 503 biased towards the upper half of the planting space 100 is used to receive the jet and tissue residue acting on the upper surface of the culture area 502 and flow to the lower half of the planting space 100.

[0054] It should be noted that the specific embodiments described above are exemplary, and those skilled in the art can devise various solutions inspired by the disclosure of this invention. These solutions all fall within the scope of this invention and its protection. Those skilled in the art should understand that this specification and its accompanying drawings are illustrative and not intended to limit the scope of the claims.
