[0002] As the use of fossil fuels increased rapidly due to industrialization, large amounts of greenhouse gases were generated. These gases absorbed and blocked infrared radiation that would otherwise be emitted into space, and by re-emitting it into the atmosphere, the greenhouse effect occurred, raising the temperature of the atmosphere.

[0003] As a result, the phenomenon of global warming is accelerating, and temperatures are expected to rise by an average of 2 to 3°C in the upcoming 2030s. Among the greenhouse gases that are the main cause of this global warming, carbon dioxide is the substance with the greatest impact.

It is expected that by the end of the 21st century, the atmospheric concentration of carbon dioxide will reach 500 ppm, which is double the pre-industrial level, and even if the rate of increase in carbon dioxide emissions stabilizes at the 1970 level, it is expected to reach 1,000 ppm after 2000.

FIG. 2 is a cross-sectional view illustrating the structure and configuration of a microalgae culture device within a carbon reduction amount calculation and management system according to the present invention. FIG. 3 is a block diagram illustrating the configuration of a carbon reduction amount calculation and management system according to the present invention. Specific details for implementing the invention

[0022] Preferred embodiments of the present invention will be described in more detail with reference to the attached drawings, provided that technical details that are already well known are omitted or compressed for the sake of brevity.

[0023] Referring to FIG. 1, the carbon reduction amount calculation and management system using the microalgae culture device of the present invention comprises: a microalgae culture device (100); a culture device management server (200); a user terminal (300); and a carbon emission rights management server (400).

[0024] The microalgae cultivation device (100) is a device that allows microalgae to be cultivated and harvested when used by a user, and also provides air purification and lighting functions. A culture medium (M) prepared for microalgae cultivation is contained within the device in an aqueous solution state, and a specific microalgae spore is inoculated into the culture medium (M) contained therein to cultivate and harvest the specific microalgae spore through the provision of air and light, thereby generating information regarding the yield of algae.

[0025] To this end, the microalgae culture device (100) includes a culture body (110), an air supply module (120), a light irradiation module (125), a microalgae harvesting unit (130, 130'), a device communication unit (140), a setting information management unit (150), a culture standard information management unit (153), a harvest information management unit (155), a first detection unit (160), a second detection unit (165), an operation control unit (170), an upper case (180), and a lower case (190).

[0026] First, the microalgae culture device (100) divides the external housing into an upper case (180) and a lower case (190), and each case is formed to be connected to one another so as to be joined or unjoined, and the culture body (110) is received and installed within the upper case (180).

[0027] Specifically, as illustrated in FIGS. 1 and 2, one side of the upper case (180) is open to provide an open space (180T) so that a user can observe the interior, thereby enabling observation of the cultivation process within the culture body (110) installed therein, as well as the output of an air purification function and a lighting function.

[0028] Here, the culture body (110) is provided with a culture medium receiving space (110T) on the inside in which a culture medium (M) is filled, and is provided as a chamber-type structure surrounded by a transparent outer wall.

[0029] The culture body (110) made of such a transparent material allows observation of the culture of microalgae proceeding in the culture medium (M) filled in the culture medium receiving space (110T), and at the same time, light is also emitted.

[0030] Additionally, as shown in FIG. 2, the culture body (110) is provided with a plurality of air outlets (111H) that are open vertically at the top and a cover portion (111) with an openable structure, so that when manual harvesting is performed through the microalgae harvesting unit (130) to be described later, the cover portion (111) is open.

[0031] In addition, external air is supplied to the culture medium (M) filled in the culture medium receiving space (110T) of the culture body (110) through the air outlet (111H) provided in the upper cover portion (111) of the culture body (110), and after being used for the cultivation of microalgae, clean air that has undergone purification treatment is discharged back to the outside.

[0032] This refers to microalgae cultured in a culture medium (M) filled within the culture medium receiving space (110T) of the culture body (110), which is a photoautotrophic organism that performs photosynthesis on Earth.

[0033] This is because they are a group of organisms that possess various photosynthetic pigments and convert inorganic matter into organic matter through the use of solar energy.

[0034] Specifically, microalgae possess the carbon assimilation function of fixing carbon dioxide using sunlight as an energy source, and through this, they produce various useful substances such as bioactive substances, thereby offering the two advantages of carbon dioxide reduction and the production of alternative fuels.

[0035] Next, the air supply module (120) constructs an air supply pipe structure connected to one side of the culture body (110) so that air sucked in from the outside is supplied and discharged into the culture medium (M) filled in the culture medium receiving space (110T) as shown in FIG. 2, thereby enabling the performance of an air purification function.

[0036] These air supply modules (120) are installed within the lower case (190).

[0037] Next, the light irradiation module (125) irradiates light having a predetermined wavelength and illuminance onto the culture medium (M) filled in the culture medium receiving space (110T) so that the culture of microalgae can be carried out.

[0038] Specifically, the light irradiation module (125) may be composed of a first light irradiation unit (125a) installed at the bottom of the upper case (180) to irradiate light from the bottom of the culture body (110) toward the top, and a plurality of second light irradiation units (125b) installed at a certain height on the side of the upper case (180) to irradiate light from the side of the culture body (110) toward the side.

[0039] Through this embodiment, instead of relying solely on irradiating light from the bottom to the top through only the first light irradiation unit (125a), as the cultivation of microalgae progresses significantly and the difference in the amount of light irradiated at specific heights increases, a change in the light irradiation pattern through multiple second light irradiation units (125b) is provided so that sufficient light can be evenly provided across all heights.

[0040] The wavelength and illuminance values ​​of the light irradiated through the first light irradiation unit (125a) and the second light irradiation unit (125b) are adjusted in correspondence with the type of microalgae to be cultured and the culture level of the microalgae, which will be explained later, and the performance of such control functions is carried out through the operation control unit (170).

[0041] Additionally, the microalgae harvesting unit (130, 130') is divided into a manual microalgae harvesting unit (130) and an automatic microalgae harvesting unit (130'), and each of these embodiments may be implemented by adopting only one or both.

[0042] First, the manual microalgae harvesting unit (130) is installed within the culture medium receiving space (110T) in the culture body (110), and after inoculating the culture medium (M) filled in the culture medium receiving space (110T) with a specific microalgae inoculum, the cultured microalgae are separated and harvested from the culture medium (M) based on a filtering operation using air supplied through the air supply module (120) and light irradiated through the light irradiation module (125).

[0043] To this end, the passive microalgae harvesting unit (130) includes a harvesting plate section (131) and a grasping column section (132) as shown in FIG. 2.

[0044] Here, the harvesting plate (131) is a plate-shaped structure that is received in the culture medium receiving space (110T) within the culture body (110) and is capable of moving up and down, and as shown in the enlarged portion of FIG. 2, a mesh-shaped filter (131H) capable of filtering microalgae and passing culture medium is provided across the entire front surface of the plate-shaped structure.

[0045] Additionally, the gripping column portion (132) is a structure that has a column shape extending upward from the upper surface of the harvesting plate portion (131) and protrudes to a height that can be grasped by the user when the cover portion (111) of the cultivation body portion (110) is opened.

[0046] Therefore, when the user wishes to manually harvest microalgae at any time, the user opens the cover portion (111) of the culture body portion (110), grasps the upper side of the grasping column portion (132), and lifts it upward, thereby allowing the microalgae to be filtered and remain by the mesh (131H) type filter structure of the harvesting plate portion (131), while the culture medium passes downward and is separated from the microalgae.

[0047] In another embodiment, an automatic microalgae harvesting unit (130') is connected and installed on one side of the culture body (110), and after inoculating a specific microalgae inoculum into a culture medium (M) filled in a culture medium receiving space (110T), the cultured microalgae are separated and harvested from the culture medium (M) based on a filtering operation using air supplied through an air supply module (120) and light irradiated through a light irradiation module (125).

[0048] To this end, the automatic microalgae harvesting unit (130') includes a circulation piping section (131'), a circulation pump section (132'), a filter section (133'), a harvesting piping section (134'), a harvesting body section (135'), a first valve section (136'), and a second valve section (137'), as shown in FIG. 2.

[0049] Here, the circulation piping section (131') corresponds to a piping facility that constructs a circulating piping structure, wherein an inlet connected to a culture medium receiving space (110T) is provided on one side of the culture body section (110) as shown in FIG. 2, and an outlet connected to a culture medium receiving space (110T) is provided on the other side of the culture body section (110).

[0050] Next, the circulation pump unit (132') is installed on one side of the circulation piping unit (131') and corresponds to a pump facility that provides a predetermined pressure to cause the culture medium (M) filled in the medium receiving space (110T) to circulate and move along one direction within the circulation piping unit (131').

[0051] Additionally, the filter section (133') is installed on one side between the inlet of the circulation piping section (131') and the circulation pump section (132'), and corresponds to a mesh-type filter that filters microalgae cultured in the culture medium (M) that moves by the pressure provided by the circulation pump section (132') and allows the culture medium (M) to pass through.

[0052] Next, the harvesting piping section (134') corresponds to a piping facility that establishes a piping structure branching from one side of the circulation piping section (131') adjacent to the filter section (133') between the inlet of the circulation piping section (131') and the filter section (133').

[0053] Additionally, the harvesting body (135') is connected to the harvesting pipe section (134') and corresponds to a structure such as a container having a microalgae harvesting space in which microalgae filtered through the filter section (133') are introduced and collected through the harvesting pipe section (134').

[0054] Additionally, the first valve section (136') is installed at a location adjacent to the inlet of the circulation piping section (131') and corresponds to a valve facility that determines the opening and closing of the path through which the culture medium (M) filled in the medium receiving space (110T) flows into the circulation piping section (131').

[0055] Finally, the second valve section (137') is installed at a location adjacent to the outlet of the circulation piping section (131') and corresponds to a valve facility that determines the opening and closing of the path through which the culture medium (M) introduced into the circulation piping section (131') is circulated and discharged back into the medium receiving space (110T).

[0056] Accordingly, the operation control unit (170), which will be described later, opens the first valve unit (136') and the second valve unit (137') in accordance with the automatic harvesting cycle or the automatic harvesting command signal, and then operates the circulation pump unit (132') so that the microalgae cultured in the filter unit (133') are filtered, and after a certain amount of time has elapsed, stops the operation of the circulation pump unit (132') and closes the first valve unit (136') first so that the microalgae filtered by the filter unit (133') can flow in and move through the harvesting pipe unit (134') and collect in the microalgae harvesting space within the harvesting body unit (135').

[0057] Next, the device communication unit (140) corresponds to a communication module that establishes a wireless communication network with a user terminal (200) and a culture device management server (300) as illustrated in FIGS. 1 and 3 to perform the transmission and reception of information and signals.

[0058] The device communication unit (140) is installed within the lower case (190).

[0059] Additionally, the setting information management unit (150) generates microalgae type setting information regarding the microalgae type to be cultured based on a microalgae type setting signal that is generated by the user or received by the device communication unit (140) after being generated by the user terminal (200), and stores and manages the information in an internal database.

[0060] This configuration information management unit (150) is installed within the lower case (190).

[0061] Here, the microalgae type setting information is information based on a microalgae type setting signal that is input and generated to specify the type of microalgae inoculum inoculated into the culture medium (M) filled in the culture medium receiving space (110T) for the current user to perform a culture operation through the microalgae culture device (100). Since the form of culture and harvesting and the calculation of carbon reduction amount are performed using this information, it varies for each type of microalgae.

[0062] In addition, the culture standard information management unit (153) stores and manages culture standard information regarding the changes in appropriate culture conditions and harvesting time according to the culture status and culture time of each type of microalgae in an internal database after setting.

[0063] This culture standard information management unit (153) is installed in the lower case (190).

[0064] Additionally, the first sensing unit (160) is installed at at least one point on one side of the culture body (110) and is provided as a sensing module capable of detecting various light irradiation levels, including an illuminance sensor that detects the amount of light irradiated through the light irradiation module (125) within the culture medium receiving space and generates first sensing information.

[0065] According to the implementation, the first detection unit (160) may be provided in multiple units as shown in FIG. 2 and installed on one side of the culture body (110) at different heights, thereby analyzing the difference in the amount of light irradiation provided from the first light irradiation unit (125a) according to the amount of microalgae being cultured in the culture medium (M) at different heights within the culture medium receiving space (110T), and based on this, the operation control unit (170) is used to control the second light irradiation unit (125b) at an appropriate height among the multiple second light irradiation units (125b) so that irradiation of light having a specific wavelength and illuminance can be carried out individually.

[0066] In addition, the second sensing unit (165) is installed at at least one point on one side of the culture body (110) and is provided as a sensing module capable of detecting various concentration levels, including an infrared sensor (IR Sensor) that detects the concentration of microalgae cultured in the culture medium (M) filled in the culture medium receiving space (110T) and generates second sensing information.

[0067] Depending on the implementation, the second sensing unit (165) may be provided in multiple numbers to distinguish and digitize the concentration levels of microalgae in the culture medium (M) at different locations within the culture medium receiving space (110T).

[0068] In conjunction with this, the operation control unit (170) selects culture standard information regarding microalgae of a specific type within the culture standard information management unit (153) according to the microalgae type setting information stored in the setting information management unit (150), and analyzes the first detection information generated through the first detection unit (160) and the second detection information generated through the second detection unit (165) based on the culture standard information, thereby adjusting the operating state of the air supply module (120) and the light irradiation module (125) to maintain optimal culture conditions and allow the cultivation of microalgae to continue.

[0069] Furthermore, the operation control unit (170) analyzes the first detection information generated through the first detection unit (160) and the second detection information generated through the second detection unit (165) based on the culture standard information to determine the appropriate harvest time for microalgae cultured in the culture medium (M), and based on this, adjusts the operating state of the first valve unit (136'), the second valve unit (137'), and the circulation pump unit (132') within the microalgae harvesting unit (130') so that automatic harvesting is performed, or generates notification information to guide the arrival of the harvest time to a pre-set user terminal (200) and transmits it through the device communication unit (140) so that the user can recognize the notification information and operate the microalgae harvesting unit (130) to perform manual harvesting.

[0070] This operation control unit (170) is housed and installed within the lower case (190).

[0071] Additionally, the harvest information management unit (155) detects the harvest amount of microalgae harvested through the microalgae harvesting unit (130, 130') and generates algae harvest information, and pairs the generated algae harvest information with the microalgae type setting information stored in the setting information management unit and transmits it to the user terminal (200) and the culture device management server (300) through the device communication unit (140).

[0072] Specifically, when a user directly operates the manual microalgae harvesting unit (130) to perform manual harvesting of microalgae, the harvest information management unit (155) determines that manual harvesting has been performed by raising and lowering the harvest plate (131) once through the harvest occurrence detection part (155a) corresponding to the motion detection sensor installed in the inner lower part of the culture body (110).

[0073] In conjunction with this, the yield calculation section (155c) generates algae harvest information by converting the yield of manually harvested microalgae into information based on the determination of the amount of change in the second detection information generated through the second detection section (165) before and after the lifting of the corresponding harvest plate section (131) determined through the harvest occurrence detection section (155a).

[0074] Additionally, when the automatic microalgae harvesting unit (130') is operated via the operation control unit (170) of the harvest information management unit (155) and the automatic harvesting of microalgae is performed, the harvest amount calculation unit (155c) generates algae harvest information by converting the harvest amount of the automatically harvested microalgae into information using the value detected through the harvest amount detection unit (155b), which is connected to one side of the harvest body (135') and corresponds to a sensor that detects the weight or concentration of microalgae collected inside the harvest body (135').

[0075] Additionally, the harvest information management unit (155) includes a harvest information storage unit (155d) that provides a storage space for internally storing algae harvest information regarding the yield of manually or automatically harvested microalgae generated through the yield calculation unit (155c).

[0076] In addition, the harvest information management unit (155) also includes a harvest information transmission unit (155e) that transmits algae harvest information regarding the yield of manually or automatically harvested microalgae generated through the yield calculation unit (155c) to a user terminal (200) and a culture device management server (300) via the device communication unit (140).

[0077] This harvest information management unit (155) is installed within the lower case (190).

[0078] The culture device management server (300) is interconnected with a plurality of microalgae culture devices (100) by establishing a wireless communication network, and calculates and generates information regarding carbon reduction amounts for each microalgae culture device (100) based on information regarding algae harvest amount received from the microalgae culture devices (100).

[0079] In addition, the culture device management server (300) operates in conjunction with the carbon emission right management server (400) to provide output of various information collected from and generated based on the microalgae culture device (100) corresponding to the user terminal (200), issue carbon emission rights based on information regarding carbon reduction amount, and enable trading of the issued carbon emission rights.

[0080] To this end, the culture device management server (300) includes a server communication unit (310), a server storage unit (320), a carbon reduction amount information management unit (330), and a carbon emission rights trading management unit (340).

[0081] First, the server communication unit (310) corresponds to a communication function configuration that establishes a wireless communication network with the microalgae culture device (100) to perform the transmission and reception of information and signals.

[0082] Next, the server storage unit (320) stores and registers information based on a reference coefficient for calculating carbon reduction amount relative to the yield of each microalgae after it has been set.

[0083] Here, the reference coefficient-based calculation formula information is information regarding a mathematical formula that can derive the carbon reduction amount according to a specific formula after multiplying the yield value for each microalgae by a reference coefficient, and is set and stored separately for each microalgae.

[0084] In addition, the server storage unit (320) constructs a database by storing specific microalgae harvest information received by each microalgae cultivation device (100) through the server communication unit (310), by classifying it by microalgae cultivation device (100).

[0085] Additionally, the carbon reduction amount information management unit (330) generates carbon reduction amount information for each microalgae cultivation device by calculating the carbon reduction amount using the algae harvesting information and microalgae type setting information received through the server communication unit (310) and the microalgae type calculation formula information corresponding to the microalgae type setting information among the microalgae type calculation formula information stored in the server storage unit (320).

[0086] Accordingly, the carbon reduction amount information management unit (330) transmits carbon reduction amount information for each generated microalgae culture device (100) to the corresponding user terminal (200) and carbon emission rights management server (400) through the server communication unit (310).
