[0031] FIG. 1 is a diagram showing a first embodiment of a building-type smart farm factory system of the present invention, FIG. 2 is a block diagram showing the building-type smart farm factory system of FIG. 1, and FIG. 3 is a flowchart of FIG. 2.

[0032] A first embodiment of the building-type smart farm factory system of the present invention will be described with reference to FIGS. 1 to 3.

[0033] To describe the building-type smart farm factory system of the present invention, the building-type smart farm factory system comprises: a power supply device (20) installed outside a building (10) equipped with several compartments, which converts solar energy into electrical energy, stores it, and supplies it to the compartments; a water supply device (30) which is driven by receiving power from the power supply device (20) or from the outside and stores and purifies the supply water; a crop cultivation device (60) which is equipped in each of the compartments (11, 12, 13), is driven by receiving power from the power supply device (20), and grows crops; and a smart cultivation means that maintains the water temperature supplied to the crop cultivation device (60) and the temperature and humidity inside the compartments (11, 12, 13) as user-set values ​​in real time by a control device (50) that monitors the water temperature and humidity inside the compartments (11, 12, 13) of the supply water purified from the water supply device (30).

[0034] The building (10) can utilize various complex buildings, such as surplus apartments or idle buildings, for the smart farm factory. The building (10) may include a power supply device (20), a water supply device (30), a culture solution supply device (40), and a crop cultivation device (60).

[0035] The power supply device (20) is provided in the basement or on the rooftop of the building (10) and can supply power to the water supply device (30), culture solution supply device (40), and crop cultivation device (60) of the building (10).

[0036] For example, the power supply device (20) can receive power from the outside and supply it to each device, or convert solar heat on the roof into electrical energy and store it as electrical energy.

[0037] Additionally, the power supply device (20) can send converted electric energy to an underground electric energy storage facility to store it, and the stored electric energy can be controlled by a control device (50) to supply it to each compartment and the supply supply device (30), the culture solution supply device (40), the crop cultivation device (60), etc.

[0038] The water supply device (30) is provided in the basement or on the roof of a building (10) and includes a water storage tank (not shown in the drawing) that collects rainwater or receives and stores water from the outside, and a water transfer pipe (31) that supplies water from the water storage tank to a crop cultivation device (60), and is monitored and controlled by a control device (50) and can be supplied in a preset amount of water.

[0039] The smart rearing means may include a culture solution supply device (40), a control device (50), and a crop cultivation device (60).

[0040] The culture solution supply device may include a culture solution storage tank (41) in which the culture solution is stored, a culture solution transfer pipe (42) for transferring the culture solution from the culture solution storage tank (41) to a crop cultivation device (60), a culture solution mixing tank (43) in which the supply water transfer pipe (31) for transferring supply water from the supply water supply device (30) to the crop cultivation device (60) and the culture solution transfer pipe (42) are connected to mix the supply water and the culture solution, a waste mixture recovery line (44) for supplying the mixture mixed in the culture solution mixing tank (43) to the crops of the crop cultivation device (60) to be absorbed by the crops and recovering the remaining waste mixture, a waste mixture storage tank (45) connected to the waste mixture recovery line (44) for storing the waste mixture, and a waste mixture purification tank (46) for receiving and purifying the waste mixture from the waste mixture storage tank (45).

[0041] The culture medium storage tank (41) can store the culture medium. The culture medium stored in the culture medium storage tank (41) is used to convert carbon into organic matter through photosynthesis of crops and plants to synthesize energy sources and intracellular components. However, indoors, it is difficult to obtain various inorganic nutrients, including carbon, for the growth and development of crops and plants.

[0042] Therefore, in a culture medium used to grow plants or microorganisms, carbon, hydrogen, and oxygen are supplied from water and carbon dioxide, while other essential nutrients can be supplied in the form of inorganic nutrients.

[0043] Generally, the nutrient solution contains nitrogen (N), phosphorus (P), and potassium (K), which are known as the three major fertilizers, as well as sulfur (S), magnesium (Mg), and calcium (Ca) as macronutrients. Micronutrients may include iron (Fe), nickel (Ni), manganese (Mn), copper (Cu), molybdenum (Mo), boron (B), chlorine (Cl), zinc (Zn), etc.

[0044] The culture medium storage tank (41) can be controlled by a control device (50) described later. The culture medium storage tank (41) may include a nutrient detection sensor provided inside to detect nutrients in the culture medium.

[0045] According to this, the control device (50) receives nutrient data detected by the nutrient detection sensor and compares it with pre-set data, and can adjust the nutrient content in the culture solution by supplying the corresponding nutrient from the outside, as different nutrients are required depending on the crop growing in the crop cultivation device (60).

[0046] The culture medium transfer pipe (42) can transfer culture medium from the culture medium storage tank to the crop cultivation device (60).

[0047] The culture solution mixing tank (43) can transfer supply water from the supply water supply device (30) to the crop cultivation device (60). The culture solution mixing tank (43) is provided on the culture solution transfer pipe (42) and can mix the supply water and the culture solution through a blade provided inside.

[0048] The waste mixture recovery line (44) can supply the mixture mixed in the culture medium mixing tank to the crops of the crop cultivation device (60) to absorb it from the crops and recover the remaining waste mixture.

[0049] The waste mixture storage tank (45) is connected to the waste mixture recovery line (44) to store the waste mixture.

[0050] The waste mixture purification tank (46) can purify waste mixture provided from the waste mixture storage tank (45). For example, the waste mixture purification tank (46) includes a separation membrane inserted into the interior for separation, and UV generating units (not shown in the drawing) are connected to both sides inside the connecting part, and coal ash and filter material may be provided in close proximity to the separation membrane.

[0051] The UV generator removes anaerobic microorganisms inhabiting the nutrient solution wastewater supplied to plants. That is, it removes anaerobic microorganisms through the UV generator surrounding the pipe through which the nutrient solution wastewater is supplied and passes.

[0052] The filter media removes foreign substances present in the nutrient solution from which anaerobic microorganisms have been removed and decomposes organic matter into ammonia (NH4). That is, Bacillus subtilis is introduced into the filter media to decompose organic matter attached to the filter media into ammonia (NH4).

[0053] Meanwhile, bottom ash or zeolite decomposes ammonia (NH4) into nitrogen dioxide (NO2) and dissolves nitrogen dioxide (NO2) into nitrate (NO3).

[0054] That is, by introducing ammonia-oxidizing bacteria into coal ash or zeolite, a nutrient solution containing ammonia (NH4) can pass through a separation membrane and decompose the ammonia (NH4) adsorbed on the coal ash or zeolite into nitrogen dioxide (NO2).

[0055] In addition, nitrite-oxidizing bacteria are introduced into coal ash or zeolite to dissolve nitrogen dioxide (NO2) into nitrate (NO3). At this time, the nutrient solution containing nitrogen dioxide (NO2) and nitrate (NO3) is supplied back to the plants.

[0056] As described above, according to the present invention, organic matter generated during the process of circulating and supplying nutrient solution to plants is decomposed into ammonia (NH4) to produce nitrogen dioxide (NO2) and nitrate (NO3), thereby preventing acidification of the nutrient solution, which can reduce plant growth inhibition and environmental pollution, and significantly reduce the cost of producing the nutrient solution by resupplying nitrogen components to the plants.

[0057] The control device (50) can control the power supply device (20), the water supply device (30), and the crop cultivation device (60) from the outside. That is, the control device (50) monitors the power supply device (20), the water supply device (30), and the crop cultivation device (60) from the outside and can be controlled according to preset values ​​for each device.

[0058] The control device (50) transmits and receives data via wired and wireless connections with the power supply device (20), the water supply device (30), and the crop cultivation device (60), including an external server, and receives data from each device in real time, stores and loads it, and controls each device accordingly.

[0059] For example, the control device (50) is connected to the power supply device (20) and can control the power supply device (20) so that the user can operate the power supply device (20) to supply power to the power supply device (30) and the crop cultivation device (60), etc.

[0060] Additionally, the control device (50) can receive data in real time from the crop cultivation device (60) and control the water supply device (30) to provide a pre-set appropriate amount of water to the crop cultivation device (60).

[0061] That is, the control device (50) can adjust the supply water by opening and closing the valve of the supply water supply device (30) when the amount of supply water provided to the crop cultivation device (60) is insufficient or excessive according to the user's monitoring or preset data value.

[0062] In addition, the control device (50) receives information on the temperature and humidity within the compartments (11, 12, 13) and can always control the temperature and humidity within the compartments to be constant.

[0063] Meanwhile, the smart nurturing means can provide steam generated by heating the supply water into the compartment (11, 12, 13) when the humidity inside the compartment is lower than the preset humidity to maintain the temperature and humidity inside the compartment at an appropriate level, or operate the drying unit when the humidity inside the compartment is higher than the preset humidity to adjust the humidity inside the compartment to the preset humidity value.

[0064] Accordingly, the smart child-rearing means may include a temperature and humidity sensing sensor that detects the temperature and humidity inside the compartment and provides it to a control device (50), a humidity control device that controls the humidity inside the compartment through the control device (50), and a cooling device and a heating device that control the temperature inside the compartment.

[0065] The cooling and heating devices operate by receiving power from the power supply device (20) and are controlled by the control device (50) to regulate the temperature and humidity inside the compartment. As this is a known technology, a detailed description thereof will be omitted.

[0066] The crop cultivation device (60) is provided in a multi-layered form in which crops are accommodated, and one or more of a deep water cultivation device (51) that sprays a mixture of supply water and culture solution at predetermined intervals onto the roots of crops, or a culture solution circulation cultivation device (52) that circulates the mixture around the roots of crops, can be controlled by the control device (50) according to the user's selection.

[0067] According to the first embodiment of this building-type smart farm factory system, the building-type smart farm factory system can operate the power supply device (30) and the crop cultivation device (60) by applying power to the power supply device (20) while the user is monitoring from the control device (50), and can operate each device.

[0068] The supply water is transferred from the supply water supply device (30) to the crop cultivation device (60), and the supply water is transferred along the supply water transfer pipe (31) and passes through the culture solution mixing tank (43), at which time the culture solution can be supplied from the culture solution supply device to the culture solution mixing tank (43) (S2).

[0069] Afterwards, the supply water and the culture solution are mixed (S3) in the culture solution mixing tank (43), and the mixture of the supply water and the culture solution can be supplied to the crop cultivation device (60) (S4).

[0070] The remaining waste mixture supplied to the crop cultivation device (60) can be stored in the waste mixture storage tank (45) through the waste mixture recovery line (44) (S5).

[0071] The amount of waste mixture in the waste mixture storage tank (45) is monitored by the control device (50), and if the amount of waste mixture exceeds the preset amount, it can be supplied to the waste mixture purification tank (46) (S6).

[0072] The purified water purified in the waste mixture purification tank (46) can be recovered back to (30) and used as a supply water to provide to the crop cultivation device (60).

[0073] Meanwhile, in stage S2, the temperature and humidity inside the compartments (11, 12, 13) can be measured to provide appropriate temperature and humidity for crops inside the compartments.

[0074] The control device (50) can adjust the temperature and humidity so that the provided temperature and humidity is maintained by comparing the provided temperature and humidity value with the temperature and humidity set by the user (S22).

[0075] Therefore, by maintaining the temperature and humidity inside the compartment at a constant level, it aids in crop growth and enables the cultivation of large quantities of crops.

[0076] Therefore, according to the building-type smart farm factory system of the present invention, since it is controlled by a control device to provide an appropriate mixture to crops, it is possible to maintain the best condition for crop cultivation at all times; furthermore, because it operates according to a pre-set system, it reduces the workload and fatigue of workers, thereby improving convenience; and since an unmanned system is possible, it has the effect of lowering labor costs.

[0077] FIG. 4 is a block diagram according to a second embodiment of the building-type smart farm factory system of the present invention, and FIG. 5 is a flowchart of FIG. 4.

[0078] A second embodiment of the building-type smart farm factory system of the present invention will be described with reference to FIGS. 4 and FIGS. 5. The building-type smart farm factory system includes a carbon dioxide detection sensor that detects the carbon dioxide concentration value in a mixture inside a compartment (11, 12, 13) and a crop cultivation device (60), and a control device (50) that receives the carbon dioxide concentration value from the carbon dioxide detection sensor and can control the amount of carbon dioxide supplied to the culture medium mixing tank (43) connected to the carbon dioxide supply tank in relation to a preset carbon dioxide concentration value.

[0079] The carbon dioxide supply device (70) may include a carbon dioxide generator (71), a carbon dioxide storage tank (72), a carbon dioxide supply pipe (73), and a carbon dioxide cooling unit (74).

[0080] A carbon dioxide generator (71) can emit CO2 by using limestone (CaCO3) and vinegar (concentrated vinegar, acetic acid) together.

[0081] The carbon dioxide generator (71) is equipped with a carbon dioxide gas permeable filler that generates carbon dioxide upon decomposition, and comprises 40-70% by weight of a substance selected from the group of magnesium carbonate, other carbonates, magnesium oxalate and other oxalates, 90-100% by weight of the total weight of the filler, 20-50% by weight of an oxidizing agent selected from the group of sodium chlorate, potassium chlorate, lithium chlorate, other metal chlorates, sodium perchlorate, potassium perchlorate, lithium perchlorate and other metal perchlorates, 1-20% by weight of carbon or other fuel, and 1-10% by weight of a binder, and an ignition part for igniting the filler, and after reducing the content of one or more by-products formed by the filler in the generated carbon dioxide or cooling the carbon dioxide generated by the filler, it can be discharged to a culture medium mixing tank (43) or a supply water transfer pipe (31) to dissolve in a mixture or discharged to a carbon dioxide storage tank (72) for storage.

[0082] As an alternative to carbon, it can be selected from Al, Ti, Mn, Fe, Mo, Ni, Mg, Co, Zn, and Cu.

[0083] The fraction of carbon may preferably be 2 weight percent or more, particularly 3 weight percent or more, particularly 4 weight percent or more, based on the weight of the filler. If carbon, aluminum or titanium provides fuel, the fraction is preferably 9 weight percent or less. In particular, the fraction may be 8 weight percent or less, more particularly 7 weight percent or less.

[0084] The fraction of Mn, Fe, Mo, Ni, Mg, Co, Zn, or Cu as fuel can advantageously be greater than 10 weight percent.

[0085] Any inorganic or organic binder suitable for binding other components to form a gas-permeable filler may be used. The binder may be composed of a substance that generates carbon dioxide upon decomposition, an oxidizer, and a substance different from the fuel.

[0086] Examples of organic binders include polytetrazole, polymer resins, nitrocellulose, and phenolic resins. Organic binders or silicone polymers can decompose and thereby form a significant amount of water vapor.

[0087] Inorganic binders can be selected particularly from the group of water glass (alkali metal silicates), mineral clays, and zeolites. These binders are suitable for providing gas-permeable fillers for use in carbon dioxide generators (71).

[0088] Here, the filler can have sufficient strength and binding properties to operate in an embodiment where the aforementioned reaction passes through the filler before and during use.

[0089] The fraction of the inorganic binder is preferably 3 weight% or more, particularly 4 weight% or more, more particularly 5 weight% or more, based on the weight of the filler. In particular, the fraction may be 9 weight% or less, 8 weight% or less, or 7 weight% or less.

[0090] Upon ignition by the igniter, spontaneous decomposition (combustion) of the packing material begins. The reaction starts on the surface of the packing material adjacent to the igniter, and proceeds through the body of the packing material toward the opposite end, towards the outlet.

[0091] Under a pressure difference, carbon dioxide generated as a result of the reaction passes through the body of the raw packing, where it is cooled, and passes through the outlet. A conduit may be provided at the outlet to lead the gas to a storage bottle or a device for use with gas.

[0092] The carbon dioxide storage tank (72) can store carbon dioxide by receiving it from the carbon dioxide generator (71). The carbon dioxide storage tank (72) can store carbon dioxide as liquid carbon dioxide by receiving it from the carbon dioxide generator (71) or from the outside.

[0093] The carbon dioxide supply pipe (73) is connected to the carbon dioxide storage tank (72) and the culture medium mixing tank (43) and can be provided to the culture medium mixing tank (43) that supplies carbon dioxide within the carbon dioxide storage tank (72).

[0094] The carbon dioxide supply pipe (73) can supply carbon dioxide to the culture medium mixing tank (43) to dissolve the carbon dioxide into the culture medium.

[0095] In this case, when mixing carbon dioxide into the culture solution, it is important to maintain an appropriate concentration by considering the type and size of the plant and environmental conditions; for instance, since excessively high carbon dioxide concentrations can be harmful to crops, the level must be kept constant at all times.

[0096] Meanwhile, since the temperature of the carbon dioxide generated from the carbon dioxide generator (71) may be too high for use on crops, the carbon dioxide can be cooled in the carbon dioxide cooling unit (74) and then transferred to the carbon dioxide storage tank (72). Here, the carbon dioxide cooling unit (74) can cool by exchanging heat with the waste mixture.

[0097] Therefore, the control device (50) can selectively provide a carbon dioxide concentration value to the culture medium by controlling the carbon dioxide supply device (70) to operate according to a carbon dioxide concentration value set by the user, thereby supplying carbon dioxide according to the set value to the culture medium.

[0098] Meanwhile, the carbon dioxide supply device (70) generates high heat during the process of generating carbon dioxide, so steam is generated, or if carbon dioxide is supplied to the culture medium and mixed, the temperature of the mixture rises.

[0099] Therefore, if the mixture is supplied to the crops while at a high temperature, it is harmful to the crops, so a mixture cooling device (80) may be included to cool the mixture to a preset temperature between the culture solution mixing tank (43) and the crop cultivation device (60).

[0100] The mixture cooling device (80) is provided in the supply water transfer pipe (31) between the culture solution mixing tank (43) and the crop cultivation device (60) to cool the mixture by exchanging heat with the mixture being transferred along the supply water transfer pipe (31).

[0101] Meanwhile, the smart growing means may include a pump (P) that pumps waste mixture discharged from the crop cultivation device (60) to the mixture cooling device (80). Additionally, the smart growing means may include a valve that opens and closes the transfer of waste mixture between the pump (P) and the crop cultivation device (60).

[0102] In addition, since the amount of carbon dioxide concentration in the mixture must be provided selectively depending on the crop, it may include a carbon dioxide removal device (90) that recovers the waste mixture, from which carbon dioxide contained in the waste mixture has been removed, back to the supply water supply device (30).

[0103] The carbon dioxide removal device (90) can remove carbon dioxide in the waste mixture by selecting either air ventilation or a chemical method. For example, the carbon dioxide removal device (90) can pass through the crop cultivation device (60) to absorb carbon dioxide in the waste mixture from the crops and remove carbon dioxide in the waste mixture with a lowered carbon dioxide concentration.

[0104] The carbon dioxide removal device (90) can absorb carbon dioxide in the waste mixture through calcium hydroxide (Ca(OH)₂) and convert it into carboxylic acid, absorb carbon dioxide in the waste mixture through potassium hydroxide (KOH) and convert it into carbonate, absorb carbon dioxide through potassium carbonate (K₂CO₃) and convert it into carbonate, or absorb carbon dioxide through potassium citrate (C6H5K₃O7) and convert it into carbonate, and the user can selectively use one or more of the above according to the amount of carbon dioxide concentration.

[0105] According to the second embodiment of the building-type smart farm factory system, the building-type smart farm factory system can operate the power supply device (30) and the crop cultivation device (60) by applying power to the power supply device (20) while the user is monitoring from the control device (50), and can operate each device.

[0106] The supply water is transferred from the supply water supply device (30) to the crop cultivation device (60), and the supply water is transferred along the supply water transfer pipe (31) and passes through the culture solution mixing tank (43), at which time the culture solution can be supplied from the culture solution supply device to the culture solution mixing tank (43) (S2).

[0107] Afterwards, the supply water and the culture solution are mixed (S3) in the culture solution mixing tank (43), and the mixture of the supply water and the culture solution is supplied (S4) to the crop cultivation device (60).

[0108] The remaining waste mixture supplied to the crop cultivation device (60) can be stored in the waste mixture storage tank (45) through the waste mixture recovery line (44) (S5).

[0109] The amount of waste mixture in the waste mixture storage tank (45) is monitored by the control device (50), and if the amount of waste mixture exceeds the preset amount, it can be supplied to the waste mixture purification tank (46) (S6).

[0110] The purified water purified in the waste mixture purification tank (46) can be recovered back to the water supply device (30) and used as a supply water to the crop cultivation device (60).

[0111] Meanwhile, in stage S2, the temperature and humidity inside the compartment can be measured to provide appropriate temperature and humidity for the crops inside the compartment.

[0112] The control device (50) can adjust the temperature and humidity so that the provided temperature and humidity is maintained by comparing the provided temperature and humidity value with the temperature and humidity set by the user (S22).

[0113] Therefore, by maintaining the temperature and humidity inside the compartment at a constant level, it aids in crop growth and enables the cultivation of large quantities of crops.

[0114] In addition, the concentration of carbon dioxide in the mixture can be measured through a carbon dioxide detection sensor after step S3 (S31).

[0115] If the carbon dioxide concentration value measured in step S31 is lower than the concentration value pre-set by the user, the carbon dioxide supply device (70) can supply carbon dioxide for the shortfall (S311).

[0116] In addition, after step S5, carbon dioxide in the waste mixture can be removed through the carbon dioxide removal device (90) during the process of transferring the waste mixture stored in the waste mixture storage tank (45) to the waste mixture purification tank (S51).

[0117] In step S51, the waste mixture from which carbon dioxide has been removed in the carbon dioxide removal device (90) can be transferred to the waste mixture purification tank (46).

[0118] According to the building-type smart farm factory system of the present invention, unused apartments or idle buildings can be utilized as smart farms, and since crops and plants can be produced, cultivated, and sold, a new revenue structure can be created, resulting in a significant improvement in usability.

[0119] Furthermore, according to the building-type smart farm factory system of the present invention, crops can be produced by selectively creating growth environments such as horizontal or vertical cultivation, deep water cultivation, or nutrient solution circulation cultivation, thereby enabling the cultivation of various species and large quantities in a limited space. Additionally, environmental pollution can be reduced because waste mixtures can be reused by heat exchange with the mixture or purification, and costs can be reduced because an optimal growth environment for plants can be created within the crop cultivation device.

[0120] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical concept or essential features of the invention.
