Description

Technical Field

[0001] The present invention relates to the field of underground space utilization, and in particular to a digital vertical ecological plant community building cabin. Background Art

[0002] The underground space environment is relatively dark, closed, and has poor air circulation. The deep underground space lacks natural light and contact with the natural environment. It not only gives people a feeling of negativity and loss, but also has a negative impact on the human body's physiological level.

[0003] Due to the growth conditions required for plant planting and the lack of natural light in deep underground spaces, artificial plants are usually used to replace natural plants in underground spaces in existing technologies. However, although the use of artificial plants for landscape layout can solve some maintenance problems, it cannot improve the spatial environment, and the comfort of underground spaces is poor.

[0004] Therefore, how to create plant communities in underground spaces that lack natural light and planting layers for plant growth, construct a sustainable plant growth microenvironment, form a benign air circulation system between vertical plant communities and human living spaces, and effectively improve the underground space environment has become an urgent problem to be solved in this field.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0033] See also Figures 1 to 3 , which shows an example of the digital vertical ecological plant community building cabin provided by the present invention.

[0034] The digital vertical ecological plant community creation cabin in this example mainly includes a modular plant planting cabin 1, a suspended bracket 2, a plant growth factor monitoring system 3, a plant growth environment control system 4, a plant growth status monitoring device 5 and a digital plant cabin control system 6.

[0035] The modular plant planting cabin 1 is set in the underground space, and soil planting components and hydroponic planting components are formed inside, which can be used to plant soil-grown plants and hydroponic plants. The plant growth factor monitoring system 3 and the plant growth status monitoring equipment 5 are configured to monitor the plant growth factor status, cabin environment status and plant growth status of soil-grown plants and hydroponic plants respectively. The digital plant cabin control system 6 is configured to control the plant growth environment control system 4 to adjust the plant growth factors and the cabin environment accordingly, which can solve the difficult problems of water, light and fertilizer requirements of vertical plant communities in closed underground spaces, build a sustainable plant growth microenvironment, and form a benign air circulation system between vertical plant communities and human living activity spaces, thereby effectively improving the underground space environment.

[0036] The modular plant planting cabin 1 includes a cabin base 11 , a cabin shell 12 , a cabin top cover 13 and a decorative cover top 14 .

[0037] Combine Figure 1 The cabin base 11 consists of a planting container 111 and a drainage board 112. The planting container 111 is preferably made of UHPC through 3D printing and is used to grow soil-grown plants. The top of the planting container 111 uses a stepped joint with reserved threaded holes to facilitate connection with the cabin shell 12. The cylindrical inner wall of the planting container 111 is provided with a limiting groove 113 to support the drainage board 112 and embedded parts for facilitating the installation of external equipment. The drainage board 112 divides the planting container 111 into a planting soil area 114 and an irrigation water storage area 115.

[0038] Furthermore, in the irrigation water storage area 114, the cylindrical wall of the planting container 111 is reserved with a water inlet 116 and a water outlet 117 for cleaning the sediment in the irrigation water storage area 114. In addition, the water inlet 116 can also serve as a ventilation hole for the planting container 111; the bottom surface of the planting container 111 is sloped from the water inlet 116 to the water outlet 117, which is convenient for the collection of irrigation water.

[0039] In addition, in the planting soil area 115, the cylindrical wall of the planting container 111 is reserved with an air inlet 118 and a fertilizer hole 119. The air inlet 118 is used to connect to the carbon dioxide supplement pipeline of the air internal and external circulation system 41 in the plant growth environment control system 4, and the fertilizer hole 119 is used to connect to the drip irrigation and fertilization pipeline of the planting soil fertility supply module 45 in the plant growth environment control system 4.

[0040] Furthermore, the drainage board 112 is preferably composed of a UHPC cover plate with folded edges all around and provided with a series of drainage channels, and a mounting hole is reserved for connecting the pumping pipe of the recharge module 44 in the plant growth environment control system 4. When in use, the folded edges of the drainage board 112 are buckled into the limiting groove 113 of the planting container 111.

[0041] In coordination therewith, the cabin shell 12 is composed of a cylindrical plate of an integrated structure, preferably a transparent acrylic cylinder, with stepped joints at the top and bottom to facilitate connection with the cabin base 11 and the cabin top cover 13.

[0042] In some embodiments, 1 to 4 operating holes and a matching removable cover plate 121 are reserved on the cabin shell 12. The cabin shell 12 is reinforced to ensure structural safety. The removable cover plate 121 is connected to the cabin base 11 to facilitate necessary manual intervention on the plants through the removable cover plate 121 during operation and maintenance.

[0043] In some embodiments, the hull shell 12 can also be composed of a number of longitudinally distributed arc plates 122 that are detachably connected and cooperated. Non-through bolt holes 123 are reserved on the upper and lower outer sides of each arc plate 122. Adjacent arc plates 122 are bolted to the shaped circular hoops 124 through the non-through bolt holes 123, which makes it easy to assemble multiple arc plates 122 into a cylinder and connect it to the hull top cover 13.

[0044] In conjunction with this, the cabin top cover 13 includes a top circular plate and side walls, and a hole or prefabricated part is reserved on the top circular plate for installing the plant intelligent fill light module 42 in the plant growth environment control system 4, which can be adaptively adjusted according to the structure of the plant intelligent fill light module 42.

[0045] In addition, an air outlet 131 and a pipe opening 132 are reserved on the side wall of the cabin top cover 13. The air outlet 131 is used to connect to the oxygen-enriched air pipe of the air internal and external circulation system 41 in the plant growth environment control system 4, and the pipe opening 132 is used for the entry and exit of water pipes and electrical lines. A through hole that cooperates with the electric telescopic device 143 of the decorative cover top 14 is also reserved on the top circular plate of the cabin top cover 13.

[0046] In conjunction with the above, the decorative cover top 14 is composed of a steel structure frame 141, a flame retardant decorative plate 142 and an electric telescopic device 143. During installation, the decorative cover top 14 is fixedly connected to the top of the underground space through the steel structure frame 141.

[0047] Furthermore, one end of the electric telescopic device 143 is connected to the steel structure frame 141, and the other end is bolted through the through hole of the top circular plate of the cabin top cover 13. In this way, driven by the electric telescopic device 143, the cabin top cover 13 can be raised and lowered, which is used to separate the cabin top cover 13 from the cabin shell 12, making it easier to install and remove the arc plate 122 of the cabin shell 12.

[0048] The modular plant planting cabin 1 thus constructed can be stably set in the underground space. In order to enable the modular plant planting cabin 1 to stably cooperate with the plant growth factor monitoring system 3, the plant growth environment control system 4 and the plant growth status monitoring equipment 5, this planting cabin also includes a suspended bracket 2.

[0049] Combine Figure 1 The suspension bracket 2 consists of a boom 21, a fixing ring 22, an annular planting tray 23, a telescopic mechanism 24, and an annular slide rail 25. One end of the boom 21 passes through a through-hole reserved in the cabin roof 13 and is bolted to the steel structure frame 141 of the decorative cover top 14. The end area where the boom 21 mates with the cabin roof 13 is equipped with a fixing ring 22. A buckle 26 is provided on the fixing ring 22 for mounting the simulated rainfall module 43 of the plant growth environment control system 4.

[0050] Furthermore, a number of annular planting trays 23 are spaced apart on the boom 21. The annular planting trays 23 are used for planting hydroponic plants. Drip irrigation pipes are laid inside for connecting to the hydroponic nutrient solution supply module 45 in the plant growth environment control system 4 to replenish water and fertility. The bottom of the annular planting tray 23 is also connected to an annular tray-shaped solenoid valve 27 and a sewage pipe 28 for water exchange in the annular planting tray 23.

[0051] At the same time, the other end of the suspension rod 21 is connected to the telescopic mechanism 24 , which is connected to the annular slide rail 25 through the telescopic mechanism 24 , so as to be slidably connected to the automatic pruning module 47 in the plant growth environment control system 4 .

[0052] In this way, the suspended bracket 2 is stably arranged in the modular plant planting cabin 1, so that the plant growth factor monitoring system 3, the plant growth environment control system 4 and the plant growth status monitoring device 5 can cooperate with the suspended bracket 2 and the modular plant planting cabin 1.

[0053] Combine Figure 1 and Figure 2 Furthermore, the plant growth factor monitoring system 3 comprises four components: a comprehensive cabin environment monitoring module 31, a comprehensive planting soil monitoring module 32, a comprehensive hydroponic nutrient solution monitoring module 33, and a plant growth factor data acquisition module. Several comprehensive cabin environment monitoring modules 31 are arranged at different heights within the modular plant growing cabin 1, enabling them to monitor parameters such as air temperature and humidity, light intensity, carbon dioxide concentration, and oxygen concentration within the modular plant growing cabin 1 in real time to determine the cabin's environmental status.

[0054] At the same time, several planting soil comprehensive monitoring modules 32 are arranged radially at different depths in the planting container 111, so that the planting soil comprehensive monitoring module 32 can monitor the temperature and humidity, nitrogen, phosphorus and potassium content, conductivity and other parameters of the planting soil in real time to obtain the status of soil-cultured plant growth elements.

[0055] Correspondingly, a hydroponic nutrient solution comprehensive monitoring module 33 is set in each group of annular planting trays 23, so that the hydroponic nutrient solution comprehensive monitoring module 33 can monitor the water level, nitrogen, phosphorus and potassium content, conductivity and other parameters of the hydroponic nutrient solution in the annular planting trays 23 in real time to obtain the status of hydroponic plant growth factors.

[0056] Therefore, the plant growth factor monitoring system 3 can obtain the cabin environment status, soil-cultured plant growth factor status and hydroponic plant growth factor status in real time through the cabin environment comprehensive monitoring module 31, planting soil comprehensive monitoring module 32 and hydroponic nutrient solution comprehensive monitoring module 33 distributed at different positions in the modular plant planting cabin 1. The plant growth factor data acquisition module can transmit the cabin environment status, soil-cultured plant growth factor status and hydroponic plant growth factor status to the digital plant cabin control system 6 in real time, providing monitoring parameters for adjusting the growth environment of soil-cultured plants and hydroponic plants.

[0057] Combine Figure 2 Furthermore, in order to adjust the growth environment of cultivated plants and hydroponic plants, the cultivation cabin also includes a plant growth environment control system 4. The plant growth environment control system 4 includes an internal and external air circulation system 41, a plant intelligent lighting module 42, a simulated rainfall module 43, a recharge module 44, a planting soil fertility supply module 45, a hydroponic nutrient solution supply module 46 and an automatic pruning module 47. Each module can cooperate with each other to adjust the plant growth factors and the cabin environment.

[0058] Combine Figure 3 and Figure 4 The air internal and external circulation system 41 is composed of a carbon dioxide adsorption / desorption device 411, a carbon dioxide release device 412, a negative ion generator 413, a wall-attached jet air supply device 413, and a delivery pipeline.

[0059] The carbon dioxide adsorption / desorption device 411 is connected in parallel with the carbon dioxide release device 412 and is linked to the underground space fresh air system. During the day, the carbon dioxide adsorption / desorption device 411 adsorbs and captures carbon dioxide in the air and discharges the purified air; a set of carbon dioxide adsorption / desorption devices 411 and the carbon dioxide release device 412 are also linked to multiple modular plant planting cabins 1 at the same time. At night, the carbon dioxide adsorption / desorption device 411 releases high-concentration carbon dioxide gas through desorption of the adsorption material, and slowly releases it through the air inlet 118 reserved on the cylindrical wall of the planting container 11 through a supplementary carbon dioxide pipeline, so that the carbon dioxide concentration in the cabin remains within the optimal range for plant photosynthesis.

[0060] In addition, if the carbon dioxide gas provided by the carbon dioxide adsorption / desorption device 411 is insufficient to meet the needs of the cabin, it will be supplemented by the carbon dioxide release device 412. The carbon dioxide release device 412 consists of a liquid carbon dioxide bottle, a pressure reducing regulating valve, and a solenoid valve. Multiple modular plant planting cabins are linked to a set of negative oxygen ion generators 413. During the day, the fan installed at the reserved air outlet 131 on the cabin roof 13 will guide the high-oxygen air in the cabin through the oxygen-enriched air pipe. After the high-oxygen air is purified by the negative oxygen ion generator 413, it is discharged by the jet air supply device 414 attached to the wall of the personnel activity area, forming an "air lake" with high oxygen content and high negative ion content in the personnel activity area.

[0061] Furthermore, the plant intelligent fill light module 42 includes an in-cabin fill light module, an out-cabin fill light module and a plant intelligent fill light control module; the in-cabin fill light module can be composed of a light pipe diffuser 421 and a ring-shaped plant lighting lamp 422, such as Figure 1 As shown, the in-cabin fill light module can also be composed of a ceiling-mounted or suspended plant light 423 to provide light for the plants in the plant container 111 and the annular planting tray 23.

[0062] The external fill-light module consists of multiple sets of automatic retractable devices and arc-shaped plant lighting lamps 424. Each set of automatic retractable devices can independently retract and extend its paired arc-shaped plant lighting lamp 424. When the light intensity inside the cabin does not meet the growth requirements of the plants, the plant intelligent fill-light control module controls the plant intelligent fill-light module 42 according to the instructions received from the digital plant cabin control system 5.

[0063] As an example, for the mode composed of the light guide diffuser 421 and the annular plant lighting lamp 422, when the natural light intensity provided by the light guide diffuser 421 does not meet the requirements, the annular plant lighting lamp 422 is started first. If the light intensity in the cabin still does not meet the requirements and there is no human activity within the lighting range of the arc-shaped plant lighting lamp 424 outside the modular plant planting cabin 1, the external cabin fill light module will be started, and each set of automatic retractable devices will automatically raise and lower the arc-shaped plant lighting lamp 424 paired with it according to the settings to provide additional fill light for the plants in the cabin.

[0064] Furthermore, the simulated rainfall module 43 is composed of a water pipe, a three-way joint, a multi-way joint, a solenoid valve, an adjustable universal sprinkler head, an adjustable pressure booster pump, a water source filter head and a simulated rainfall controller module; the water inlet of the booster pump is connected to the water source filter head through a water pipe, and the water outlet is connected to the multi-way joint. Each interface is equipped with a solenoid valve, the solenoid valve is connected to the water pipe, and the water pipe is connected to the cabin through the pipe hole 132 reserved on the side wall of the cabin top cover 13 and installed on the fixed ring 22 of the suspended bracket 2. The adjustable universal sprinkler head is connected to the water pipe through a three-way joint; when the planting soil humidity or the air humidity is lower than the requirement, the simulated rainfall controller module controls the simulated rainfall module through the solenoid valve to perform simulated rainfall operation according to the instructions received from the digital plant cabin control system 6, and controls the water pressure through the adjustable pressure booster pump to adjust the rainfall intensity.

[0065] In addition, the recharge module 44 includes a pressure-type mud and water pump 441, a pumping pipe 442, a drip irrigation pipe 443, a water level probe, a disinfection and sterilization module and a recharge control module. The connection between the pumping pipe 441 and the installation hole of the drainage board 112 must be treated with anti-seepage treatment to avoid excessive gaps causing loss of planting soil.

[0066] Furthermore, the water level probe includes an upper limit water level control probe 444 and a lower limit water level control probe 445. When the water level in the irrigation water storage area 115 of the planting container 111 rises to the upper limit water level control probe 444, the upper limit water level control probe 444 sends information to the recharge control module to control the pressure-type mud water pump 441 to start replenishing water to the planting soil, and transmits water to the drip irrigation pipe 443 through the pumping pipe 442 for drip irrigation. When the water level drops to the lower limit water level control probe 445, the pressure-type mud water pump 441 is controlled to stop operating.

[0067] At the same time, a disinfection and sterilization module is installed in the irrigation water storage area 115 of the planting container 11 to perform disinfection and sterilization using ultraviolet rays.

[0068] Combine Figure 6 Furthermore, the soil fertility replenishment module 45 includes an automatic nutrient solution mixing and dilution device 451, a drip irrigation and fertigation pipeline, and a soil fertility replenishment controller module. The automatic nutrient solution mixing and dilution device 451 comprises a concentrated nutrient solution storage tank 4511, a nutrient solution dilution tank 4512, a pumping module, a liquid level sensor 4513, and a water storage tank 4514. It is used to mix and dilute concentrated nutrient solutions of different ingredients according to a specific ratio to create a mixed nutrient solution.

[0069] Among them, a liquid level sensor 4513 is installed at the bottom of the water tank 4514 and the nutrient solution dilution tank 4512, and a first liquid suction pipe 4515 and a third liquid suction pipe 4517 are installed respectively. The first liquid suction pipe 4515 is connected to a micro self-priming pump 4518, and one end of the third liquid suction pipe 4517 is connected to a pressure-type self-priming pump 4519, and the other end is connected to the drip irrigation and fertilization pipeline through a filter head.

[0070] In addition, a magnetic stirring base is built into the lower interlayer of the nutrient solution dilution tank 4511, and the magnetic stirring base can be used to control the magnetic stirring bar in the nutrient solution dilution tank 4511 to rotate in a circular motion, so as to evenly stir the concentrated nutrient solution and water.

[0071] Several concentrated nutrient solution storage tanks 4512 contain different types of nutrient solutions. A liquid level sensor 4513 is installed at the bottom of the concentrated nutrient solution storage tank 4512, and a second liquid suction pipe 4526 is installed. The second liquid suction pipe 4526 is connected to a micro self-priming pump 4518. At the same time, the micro self-priming pump 4518 is connected to the nutrient solution dilution tank 4511. The liquid level sensor 4513 detects that the liquid inside the concentrated nutrient solution storage tank drops to the alarm value, and the concentrated nutrient solution storage tank will be replenished with concentrated nutrient solution.

[0072] When the planting soil fertility is insufficient, the planting soil fertility replenishment controller module controls the micro self-priming pump 4518 according to the instructions received from the digital plant cabin control system 6 to pump different types of concentrated nutrient solutions in the concentrated nutrient solution storage tank 4512 and the water pump in the water tank 4514 to the nutrient solution dilution tank 4511, and then controls the magnetic stirring bar in the nutrient solution dilution tank 4511 to rotate in a circle through the magnetic stirring base to mix the concentrated nutrient solution and water evenly, and transports the nutrient solution to the drip irrigation and fertilization pipeline through the pressure-type self-priming pump 4519, and then transports it to the fertilizer hole 119 on the cylindrical wall of the planting container 111 for planting soil fertility replenishment.

[0073] Similarly, the hydroponic nutrient solution supply module 46 is composed of an automatic nutrient solution proportioning and dilution device, a main infusion pipe and a hydroponic nutrient solution supply controller module. The automatic nutrient solution proportioning and dilution device has the same structure as the automatic nutrient solution proportioning and dilution device 451 in the planting soil fertility supply module 45, and will not be repeated here.

[0074] Furthermore, the main liquid delivery pipe is connected to the cabin through the pipe hole 132 reserved on the side wall of the cabin top cover 13, and is respectively connected to the drip irrigation pipe in each annular planting tray 23.

[0075] When the hydroponic nutrient solution comprehensive monitoring module 33 detects that the fertility of the hydroponic nutrient solution is insufficient, the hydroponic nutrient solution supply controller module receives an instruction from the digital plant cabin control system 6, opens the ring tray-shaped solenoid valve 27 at the bottom of the annular planting tray 23, and flows the remaining hydroponic nutrient solution to the irrigation water storage area 115 through the sewage pipe 28. Further, the ring tray-shaped solenoid valve 27 at the bottom of the annular planting tray 23 is closed, and the nutrient solution in the automatic proportioning and dilution device is transported to the drip irrigation pipe to replenish the hydroponic nutrient solution to the annular planting tray 23.

[0076] In this way, the rainfall from the simulated rainfall module 42 and the remaining liquid in the annular planting tray 23 flow into the irrigation water storage area 115, causing the water level in the irrigation water storage area 115 to rise, and the upper limit water level control probe 444 in the recharge system 44 sends information to the recharge control module, controlling the pressure-type mud water pump 441 to start and replenish water to the planting soil, and transmitting the water to the drip irrigation pipe 443 through the pumping pipe 442 for drip irrigation, thereby forming a water circulation in the modular plant planting cabin 1.

[0077] Combine Figure 1 Furthermore, the automatic pruning module 47 is equipped with a pruning image recognition system, a pruning plant growth model, a laser emitter 471, a slide 472 and an automatic pruning controller module, and is mainly used for pruning branches of soil-grown plants.

[0078] Specifically, the pruning image recognition system and the laser emitter 471 are installed on the slide 372, and the slide 372 is slidably connected to the annular slide rail 25 of the suspension bracket 2, so that the slide 372 can drive the pruning image recognition system and the laser emitter 471 to perform uniform circular motion along the annular slide rail 25 to scan the soil-grown plants.

[0079] The pruning image recognition system scans soil-grown plants and generates branch point clouds, regularly captures multi-perspective image data of soil-grown plants, and uploads the data to the digital plant cabin control system 6 via the automatic pruning controller module. The branch point cloud data is processed by the data processing module in the digital plant cabin control system 6 to obtain the three-dimensional coordinates of the branches. The branch growth direction is predicted by the plant growth model in the digital plant cabin control system 6 to evaluate the branch pruning level.

[0080] As an example, for branches that meet the pruning requirements, the digital plant cabin control system 6 adjusts the angle of the laser emitter 471 through the automatic pruning controller module, and emits a laser of a specific wavelength to prune the branches; considering the operational safety and laser emitter power issues, the automatic pruning module 47 is preferably used for non-lignified or semi-lignified branches.

[0081] Therefore, the plant growth environment control system 4 cooperates with the air internal and external circulation system 41, the plant intelligent lighting module 42, the simulated rainfall module 43, the re-injection module 44, the planting soil fertility supply module 45, the hydroponic nutrient solution supply module 46 and the automatic pruning module 47 to adjust the plant growth factors and the cabin environment.

[0082] In addition, the plant growth chamber also includes a plant growth status monitoring device 5, which includes a bionic self-propelled chassis and a high-definition camera system. The high-definition camera system is installed on the bionic self-propelled chassis and regularly inspects the modular plant cultivation chamber 1 according to the path planned by the digital plant chamber control system 6. It moves around the modular plant cultivation chamber 1, allowing the high-definition camera system to accurately capture digital image information of the plants in the chamber and upload it to the digital plant chamber control system 6. The data analysis module in the digital plant chamber control system 6 uses big data analysis and artificial intelligence algorithms to perform in-depth data analysis, evaluate the overall growth status of the soil-grown and hydroponic plants in the chamber, and respectively obtain the growth status of the soil-grown and hydroponic plants. When the evaluation result falls below the set value, the digital plant chamber control system 6 issues an early warning, reminding technicians to take timely measures.

[0083] Combine Figure 2 In order to stably control the plant growth factor monitoring system 3, the plant growth environment control system 4, and the plant growth status monitoring equipment 5, the digital plant cabin control system 6 includes a data receiving module, a data visualization module, a data processing module, a plant growth model and a data analysis module. It can receive and process the data monitored by the plant growth factor monitoring system 3, the plant growth environment control system 4, and the plant growth status monitoring equipment 5, and then visualize it through the data visualization module and issue corresponding control instructions.

[0084] Furthermore, the cabin environment status, soil-cultured plant growth factor status and hydroponic plant growth factor status monitored by the plant growth factor monitoring system 3 are uploaded to the data receiving module of the digital plant cabin control system 6. After data processing by the data processing module, they are visualized by the data visualization module, including parameters such as temperature and humidity, nitrogen, phosphorus and potassium content, and conductivity of the planting soil, parameters such as temperature and humidity, light, carbon dioxide concentration and oxygen concentration of the air in the modular plant planting cabin 1, and parameters such as water level, nitrogen, phosphorus and potassium content, and conductivity of the hydroponic nutrient solution in the annular planting tray 24; the monitoring values ​​of the above parameters are fed back to the data analysis module. When they exceed or fall below the set values, the digital plant cabin control 6 system sends instructions to each module.

[0085] As an example, if the carbon dioxide gas provided by the carbon dioxide adsorption / desorption device 411 is insufficient to meet the needs of the cabin, the digital plant cabin control 6 sends an instruction to the air internal and external circulation system 41, which will be supplemented by the carbon dioxide release device 412; when the fertility of the planting soil is insufficient, the digital plant cabin control 6 sends an instruction to the planting soil fertility supply module 45 to automatically proportion and dilute the nutrient solution, and to perform drip irrigation and fertilization of the mixed nutrient solution; when the air humidity is lower than the requirement, the digital plant cabin control 6 sends an instruction to the simulated rainfall module 43 to perform simulated rainfall operations; when the humidity of the planting soil is lower than the design requirement, the digital plant cabin control 6 sends an instruction to the simulated rainfall module 43 to perform simulated rainfall operations; when the humidity of the planting soil is lower than the design requirement, the digital plant cabin control 6 sends an instruction to the simulated rainfall module 43 to perform simulated rainfall operations. The recharge module 44 sends an instruction to start the pressure-type mud water pump of the recharge module to replenish water for the planting soil. If the moisture of the planting soil still does not meet the requirements when the water level drops to the lower limit water level control point, an instruction is sent to the simulated rainfall module 43 to perform a simulated rainfall operation; when the light intensity in the cabin does not meet the growth needs of the plants, the digital plant cabin control 6 sends an instruction to the plant intelligent fill light module 42 to perform the plant fill light operation; when the fertility of the hydroponic nutrient solution in the annular planting tray 24 is insufficient, the digital plant cabin control 6 sends an instruction to the hydroponic nutrient solution supply module 46 to automatically update the hydroponic nutrient solution and discharge the liquid to the irrigation water storage area 115.

[0086] Furthermore, the branch point cloud data and image data acquired by the pruning image recognition system of the automatic pruning module 47 are uploaded to the data receiving module of the digital plant cabin control system 6. The branch point cloud data is processed by the data processing module to obtain the three-dimensional coordinates of the branch. The growth direction of the branch is predicted by the plant growth model. The three-dimensional coordinate information of the branch and the branch growth prediction results are fed back to the data analysis module for evaluating the branch pruning level. For branches that meet the pruning requirements, the digital plant cabin control system 6 sends instructions to the automatic pruning module 47, automatically adjusts the angle of the laser emitter 471, and emits a laser of a specific wavelength to prune tender branches.

[0087] Correspondingly, the high-definition camera system of the plant growth status monitoring equipment 5 uploads the image data of the plants in the cabin to the data receiving module of the digital plant cabin control system 6. The data analysis module uses big data analysis and artificial intelligence algorithms to conduct in-depth data analysis to evaluate the overall growth status of the plant community in the cabin. The evaluation results are fed back to the data visualization module. If the evaluation result shows that the growth status is poor, the digital plant cabin control system 6 will issue an early warning to remind technical personnel to take timely measures.

[0088] This constitutes the digital vertical ecological plant community building cabin provided by the present invention.

[0095] (6) After the test meets the requirements, the cabin shell 12 is installed in sequence; then the arc plate 122 of the cabin shell 12 is assembled into a cylinder using the shaping hoop 124, and then the electric telescopic device 143 of the decorative cover top 14 is controlled to lift the cabin top cover 13; then the electric telescopic device 143 of the decorative cover top 14 is controlled to lower the cabin top cover 13, completing the bolting of the cabin shell 12 and the cabin top cover 13; finally, the shaping hoop 124 on the cabin shell 12 is removed.

The digital plant cabin control system 6 controls the working status of the plant growth environment control system 4 according to the status of plant growth factors, the cabin environment and the plant growth status, and adjusts the plant growth factors and the cabin environment.

[0098] If the carbon dioxide gas provided by the carbon dioxide adsorption / desorption device 411 is insufficient to meet the needs of the cabin, the digital plant cabin control 6 sends a command to the air internal and external circulation system 41, which will be supplemented by the carbon dioxide release device 412; when the fertility of the planting soil is insufficient, the digital plant cabin control 6 sends a command to the planting soil fertility replenishment module 45 to automatically proportion and dilute the nutrient solution, and to perform drip irrigation and fertilization of the mixed nutrient solution; when the air humidity is lower than the requirement, the digital plant cabin control 6 sends a command to the simulated rainfall module 43 to simulate rainfall operation; when the planting soil humidity is lower than the design requirement, the digital plant cabin control 6 sends a command to the recharge ....

[0099] Furthermore, the branch point cloud data and image data acquired by the pruning image recognition system of the automatic pruning module 47 are uploaded to the data receiving module of the digital plant cabin control system 6. The branch point cloud data is processed by the data processing module to obtain the three-dimensional coordinates of the branch. The growth direction of the branch is predicted by the plant growth model. The three-dimensional coordinate information of the branch and the branch growth prediction results are fed back to the data analysis module for evaluating the branch pruning level. For branches that meet the pruning requirements, the digital plant cabin control system 6 sends instructions to the automatic pruning module 47, automatically adjusts the angle of the laser emitter 471, and emits a laser of a specific wavelength to prune tender branches.

[0100] Correspondingly, the high-definition camera system of the plant growth status monitoring equipment 5 uploads the image data of the plants in the cabin to the data receiving module of the digital plant cabin control system 6.
