Also, in each drawing and in this specification, the same reference numerals indicate similar elements. FIG. 1 is a block diagram showing an example of the configuration of a management system 1 according to an embodiment and the main components included in the management system 1. Note that each component of each device may be built-in or external. The management system 1 provides an algae cultivation service. The algae cultivation service is a service that allows users of the algae cultivation service (hereinafter simply referred to as "users") to purchase plots of algae cultivation equipment. The algae cultivation service cultivates algae using the cultivation equipment. The algae cultivated in the management system 1 are, for example, microalgae. The management system 1 has a function for cultivating algae using the cultivation equipment. The algae cultivation service also awards points (hereinafter referred to as "cultivation points") to users based on the amount of carbon dioxide absorption (fixed amount) or the degree of cultivation of the algae cultivated using the cultivation equipment purchased by the user. The management system 1 includes, as an example, a server device 100, a cultivation system 200, and a terminal device 300. Note that the management system 1 may include only some of these.

The network NW may be a communication network including a LAN (local area network). The network NW may be a wireless line or a wired line, or may be a combination of wireless and wired lines. The network NW may also be a communication network including a dedicated line or a public mobile phone network.

[0010] The server device 100 is, for example, a device for providing an algae cultivation service. The server device 100, for example, manages the entire algae cultivation service. The server device 100, for example, controls the cultivation system 200. The server device 100 includes, for example, a processor 110, a ROM (read-only memory) 120, a RAM (random-access memory) 130, an auxiliary storage device 140, and a communication interface 150. A bus 160 and the like connect these components. The server device 100 is an example of an incentive granting device.

[0011] The processor 110 is the central part of a computer that performs various calculations and processes, such as calculations and controls, necessary for the operation of the server device 100. The processor 110 may be, for example, a central processing unit (CPU), a microprocessing unit (MPU), a system on a chip (SoC), a digital signal processor (DSP), a graphics processing unit (GPU), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). Alternatively, the processor 110 may be a combination of these. The processor 110 may also be a combination of these with a hardware accelerator or the like. The processor 110 controls each component to realize various functions of the server device 100 based on programs such as firmware, system software, and application software stored in the ROM 120 or the auxiliary storage device 140. The processor 110 also executes the processes described below based on the programs. Note that some or all of the programs may be incorporated into the circuitry of the processor 110.

[0012] The ROM 120 and RAM 130 are the main storage devices of the computer centered around the processor 110. The ROM 120 is a non-volatile memory used exclusively for reading data. The ROM 120 stores, for example, firmware among the above programs. The ROM 120 also stores data used by the processor 110 when it performs various processes.

[0013] The RAM 130 is a memory used for reading and writing data. The RAM 130 is used as a work area for storing data that is temporarily used when the processor 110 performs various processes. The RAM 130 is typically a volatile memory.

[0014] The auxiliary storage device 140 is an auxiliary storage device of a computer centered around the processor 110. The auxiliary storage device 140 is, for example, an EEPROM (electric erasable programmable read-only memory), an HDD (hard disk drive), or a flash memory. The auxiliary storage device 140 stores, for example, system software and application software among the above programs. The auxiliary storage device 140 also stores data used by the processor 110 when performing various processes, data generated by the processes in the processor 110, various setting values, and the like.

[0015] The data stored in the auxiliary storage device 140 includes, for example, a user DB (database) 141, a cultivation DB (database) 142, and a culture solution DB 143.

[0016] User DB141 is a database that stores and manages information about users. For example, for each user, user DB141 stores the user information in association with a user ID (identifier). In this way, user DB141 stores and manages information about each user. Note that the user ID is identification information unique to each user. User information is information about a user identified by the associated user ID. User information includes, for example, purchase list information and point information.

[0017] The purchase list information is information that indicates a list of sections 222 that a user has purchased. In other words, the purchase list information is information that indicates a list of sections 222 of which the user is the owner. The purchase list information indicates a list of sections 222 that the user has purchased, for example, by including the section ID of each section 222 that the user has purchased. The section ID is identification information that is unique for each section 222. Sections 222 will be described later.

[0018] The point information is information indicating the number of cultivation points held by the user. The cultivation points are points granted to the user in the algae cultivation service. The cultivation points may be points exclusive to the algae cultivation service, or points that can be used in other services. The cultivation points may also be electronic money. The user can exchange the cultivation points for goods or services. The goods or services are, for example, goods related to algae and services related to algae. The goods related to algae are, for example, goods made using algae. The cultivation points are an example of an incentive granted to the owner of the plot 222.

[0019] The cultivation DB 142 is a database that stores and manages information about the algae cultivated in the algae cultivation service. For example, the cultivation DB 142 stores, for each partition 222, partition information in association with a partition ID. The partition information is information about the partition 222 identified by the associated partition ID. The partition information includes allocation information, culture solution information, absorbance information, and partition point information. The allocation information indicates whether the partition 222 is assigned to a user, and to which user it is assigned. The user assigned to the partition 222 indicates the owner of the partition 222. If the partition 222 is assigned to a user, the allocation information includes the user ID of the user. The culture solution information indicates the culture solution ID of the culture solution in the partition 222. The culture solution ID is identification information unique to each culture solution. The absorbance information indicates the absorbance of the algae solution in the partition 222. The partition point information is information indicating the amount of points generated by the partition 222.

[0020] The culture solution DB 143 is a database that stores and manages information about the culture solution used to cultivate algae in the algae cultivation service. For each culture solution, the culture solution DB 143 stores culture solution information in association with a culture solution ID. The culture solution information includes the name of the culture solution, the price of the culture solution, the composition of the culture solution, and information indicating the characteristics of the culture solution. Examples of the components of the culture solution include water, nitrogen, ammonium salts, nitrates, other inorganic nitrogen sources, peptone, urea, other organic nitrogen sources, phosphorus, phosphates, dipotassium hydrogen phosphate, potassium dihydrogen phosphate, calcium phosphate, sulfur, magnesium sulfate, zinc sulfate, ferrous sulfate, copper sulfate, calcium sulfate, calcium chloride, boric acid, manganese chloride, hexaammonium heptamolybdate, zinc sulfate, ferrous sulfate, copper sulfate, and other minerals. The information indicating the characteristics of the culture solution includes information indicating the main use of the algae cultivated using the culture solution.

[0021] The culture medium DB 143 stores information on a plurality of types of culture medium with predetermined compositions.

[0022] The communication interface 150 is an interface for the server device 100 to communicate via a network NW or the like.

[0023] The bus 160 includes a control bus, an address bus, a data bus, etc., and transmits signals exchanged among the various components of the server device 100 .

[0024] The culture system 200 will be described with reference to Fig. 2 in addition to Fig. 1. Fig. 2 is a perspective view showing an example of a culture system 220. The culture system 200 is a system for cultivating algae. The culture system 200 cultivates algae, for example, by cultivating the algae. The culture system 200 includes, as an example, a culture control device 210, a culture device 220, an absorbance measurement device 230, and a camera 240. Note that the number of the culture control device 210, the culture device 220, the absorbance measurement device 230, and the camera 240 is not limited.

[0025] The culture control device 210 is a device that controls the culture device 200 that cultures algae. The culture control device 210 includes, for example, a processor 211, a ROM 212, a RAM 213, an auxiliary storage device 214, a communication interface 215, and a control interface 216. A bus 217 and the like connect these components together.

[0026] The processor 211 is the central part of a computer that performs various calculations and processes, such as calculations and controls, necessary for the operation of the culture system 200. The processor 211 is, for example, a CPU, an MPU, an SoC, a DSP, a GPU, an ASIC, a PLD, or an FPGA. Alternatively, the processor 211 may be a combination of several of these. The processor 211 may also be a combination of these with a hardware accelerator or the like. The processor 211 controls each unit to realize various functions of the culture system 200 based on programs such as firmware, system software, and application software stored in the ROM 212 or the auxiliary storage device 214. The processor 211 also executes the processes described below based on the programs. Note that part or all of the programs may be incorporated into the circuitry of the processor 211.

[0027] The ROM 212 and RAM 213 are main storage devices of the computer centered around the processor 211. The ROM 212 is a non-volatile memory used exclusively for reading data. The ROM 212 stores, for example, firmware among the above programs. The ROM 212 also stores data used by the processor 211 when performing various processes.

[0028] The RAM 213 is a memory used for reading and writing data. The RAM 213 is used as a work area for storing data that is temporarily used when the processor 211 performs various processes. The RAM 213 is typically a volatile memory.

[0029] The auxiliary storage device 214 is an auxiliary storage device of a computer with the processor 211 as its central device. The auxiliary storage device 214 is, for example, an EEPROM, a HDD, or a flash memory. The auxiliary storage device 214 stores, for example, system software and application software among the above programs. The auxiliary storage device 214 also stores data used by the processor 211 when performing various processes, data generated by the processes in the processor 211, and various setting values. The auxiliary storage device 214 also stores data similar to that of the culture solution DB 143.

[0030] The communication interface 215 is an interface for the culture system 200 to communicate via a network NW or the like.

[0031] The control interface 216 is an interface through which the culture control device 210 communicates with each device such as the culture device 220, the absorbance measurement device 230, and the camera 240. The culture control device 210 controls each of these devices via the control interface 216.

[0032] The bus 217 includes a control bus, an address bus, a data bus, etc., and transmits signals exchanged among the various parts of the culture control device 210 .

[0033] The culture device 220 is a device for culturing algae. The culture device 220 includes one or more containers 221. The culture device 220 shown in FIG. 2 includes two containers 221. The containers 221 contain a culture solution. The culture device 220 cultivates the algae in the culture solution. The algae and culture solution in one container 221 are designed to not mix with the algae and culture solution in another container 221. It is preferable that at least a portion of the wall and bottom of the container 221 are transparent so that the inside can be seen. The culture device 220 has a function of placing the culture solution in the container 221. The culture device 220 also has a function of changing the culture solution in the container 221 to a culture solution with a different composition. The culture device 220 changes the culture solution in the container to a culture solution with a different composition, for example, by replacing the culture solution. The culture device 220 changes the culture solution in the container to a culture solution with a different composition, for example, by adjusting the components of the culture solution in the container. The culture device 220 is an example of a cultivation device that cultivates microalgae. The culture device 220 also functions as an example of a changer that changes the composition of the culture solution based on the control of the controller.

[0034] The culture device 220 includes, for example, one or more compartments 222. Typically, one container 221 corresponds to one compartment 222. However, one container 221 may correspond to multiple compartments 222. Furthermore, multiple containers 221 may correspond to one compartment 222. The culture device 220 shown in FIG. 2 includes two compartments 222. Note that the culture system 200 typically includes multiple culture devices 220 installed side by side. A user can purchase a compartment 222 within the algae cultivation service. However, purchasing a compartment 222 in the algae cultivation service does not necessarily transfer ownership of the compartment 222 to the user, nor does it necessarily mean that the user is leased the compartment 222. The purchase of a compartment 222 in the algae cultivation service includes at least a promise or contract that the user who purchases the compartment 222 will be awarded cultivation points based on the amount of carbon dioxide absorption or the degree of growth of the algae cultivated in the compartment 222. However, the purchase of the plot 222 in the algae cultivation service may actually involve a transfer of ownership or lease of the plot 222.

[0035] The culture device 220 is equipped with an absorbance measuring device 230. At least one absorbance measuring device 230 is attached to the culture device 220 for each container 221 or each compartment 222. The absorbance measuring device 230 is a device that measures the absorbance of the algal liquid in the container 221. The absorbance measuring device 230 includes, for example, an emitter 231 and a sensor unit 232. The emitter 231 and the sensor unit 232 are attached, for example, to the outside of a transparent wall or bottom surface of the container 221 so as to face each other. The emitter 231 emits electromagnetic waves such as visible light toward the sensor unit 232. The electromagnetic waves may be monochromatic light. The electromagnetic waves emitted by the emitter 231 pass through the wall surface of the container 221, the algal liquid in the container 221, and the wall surface of the container 221 opposite the wall surface, and are incident on the sensor unit 232. The sensor unit 232 measures the intensity of the incident electromagnetic waves. The absorbance measuring device 230 measures absorbance, for example, based on the ratio of the intensity of incident light to that of transmitted light. The incident light is electromagnetic waves emitted by the emission unit 231. The transmitted light is electromagnetic waves incident on the sensor unit 232. The emission unit 231 and the sensor unit 232 may be attached to the inside of the wall or bottom of the container 221. In this case, the wall or bottom to which the emission unit 231 and the sensor unit 232 are attached does not need to be transparent. In this case, the electromagnetic waves emitted by the emission unit 231 pass through the algae liquid in the container 221 and enter the sensor unit 232.

[0036] The absorbance is an example of a physical quantity that indicates the growth level of microalgae, and the absorbance measuring device 230 is therefore an example of a measuring device that measures a physical quantity that indicates the growth level of microalgae.

[0037] The camera 240 photographs the culture device 220. The culture system 220 is provided with, for example, one or more cameras 240 for each container 221 or each compartment 222. The culture system 220 may be provided with a camera 240 that can photograph multiple containers 221 or multiple compartments 222. In this case, the culture system 220 may be provided with one or more cameras 240 for each of the multiple containers 221 or each of the multiple compartments 222. The camera 240 photographs the culture device 220 and outputs the data as image data. Note that a moving image is a type of image.

[0038] The terminal device 300 is, for example, a device used by a user of the algae cultivation service. The terminal device 300 is, for example, a personal computer (PC), a tablet terminal, or a smartphone. The terminal device 300 includes, for example, a processor 310, a ROM 320, a RAM 330, an auxiliary storage device 340, a communication interface 350, an input device 360, and a display device 370. A bus 380 and the like connect these components.

[0039] The processor 310 is the central part of a computer that performs various calculations and processes, such as calculations and controls, necessary for the operation of the terminal device 300. The processor 310 may be, for example, a CPU, MPU, SoC, DSP, GPU, ASIC, PLD, or FPGA. Alternatively, the processor 310 may be a combination of several of these. The processor 310 may also be a combination of these with a hardware accelerator. The processor 310 controls each component to realize various functions of the terminal device 300 based on programs such as firmware, system software, and application software stored in the ROM 320 or the auxiliary storage device 340. The processor 310 also executes the processes described below based on the programs. Note that some or all of the programs may be incorporated into the circuitry of the processor 310.

[0040] ROM 320 and RAM 330 are the main storage devices of the computer centered around processor 310. ROM 320 is a non-volatile memory used exclusively for reading data. ROM 320 stores, for example, firmware among the above programs. ROM 320 also stores data used by processor 310 when performing various processes.

[0041] The RAM 330 is a memory used for reading and writing data. The RAM 330 is used as a work area for storing data that is temporarily used when the processor 310 performs various processes. The RAM 330 is typically a volatile memory.

[0042] The auxiliary storage device 340 is an auxiliary storage device of a computer centered around the processor 310. The auxiliary storage device 340 is, for example, an EEPROM, a HDD, or a flash memory. The auxiliary storage device 340 stores, for example, system software and application software among the above programs. The auxiliary storage device 340 also stores data used by the processor 310 when performing various processes, data generated by the processes in the processor 310, various setting values, and the like.

[0043] The programs stored in the ROM 320 or the auxiliary storage device 340 include terminal applications. Terminal applications are application software used to utilize the algae cultivation service. The terminal application may be application software dedicated to the algae cultivation service, or general-purpose application software such as a web browser.

[0044] The communication interface 350 is an interface for the terminal device 300 to communicate via a network NW or the like.

[0045] The input device 360 ​​accepts operations by the operator of the terminal device 300. The input device 360 ​​is, for example, a keyboard, a keypad, a touchpad, a mouse, a controller, etc. The input device 360 ​​may also be a device for voice input.

[0046] The display device 370 displays a screen for notifying various types of information to the operator of the terminal device 300 or the like. The display device 370 is, for example, a display such as a liquid crystal display or an organic EL (electro-luminescence) display. A touch panel can also be used as the input device 360 ​​and the display device 370. That is, a display panel included in the touch panel can be used as the display device 370, and a pointing device for touch input included in the touch panel can be used as the input device 360.

[0047] The bus 380 includes a control bus, an address bus, a data bus, etc., and transmits signals exchanged between the various parts of the terminal device 300 .

[0048] The operation of the management system 1 according to the embodiment will be described below with reference to FIGS. 3 to 5. Note that the content of the processing in the following operational description is merely an example, and various processes capable of achieving similar results can be used as appropriate. FIG. 3 is a flowchart showing an example of processing by the processor 110 of the server device 100. The processor 110 executes the processing of FIG. 3 based on a program stored in, for example, the ROM 120 or the auxiliary storage device 140. FIG. 4 is a flowchart showing an example of processing by the processor 211 of the culture control device 210. The processor 211 executes the processing of FIG. 4 based on a program stored in, for example, the ROM 212 or the auxiliary storage device 214. FIG. 5 is a flowchart showing an example of processing by the processor 310 of the terminal device 300. The processor 310 executes the processing of FIG. 5 based on a program stored in, for example, the ROM 320 or the auxiliary storage device 340. The processor 310 executes the processing of FIG. 5 based on, for example, a terminal app.

[0049] The processor 310 initiates the process shown in Figure 5, for example, in response to the launch of a terminal app. Alternatively, the processor 310 initiates the process shown in Figure 5 in response to accessing a web page for the algae cultivation service using a web browser. Note that in order to use some or all of the functions of the algae cultivation service, it is necessary to log in to the algae cultivation service. The terminal device 300 logs in to the algae cultivation service using, for example, a user ID. This login may be automatic, or may require operation by the operator of the terminal device 300. When the terminal device 300 is currently logged in to the algae cultivation service, it stores at least either the user ID used to log in and the session ID assigned during this login. This user ID or session ID will be referred to below as a "login ID." However, for simplicity, the following description will be given assuming that the login ID is a user ID. Furthermore, the user identified by this user ID will be referred to below as a "logged-in user."

[0050] In step ST41 of Figure 5, the processor 310 of the terminal device 300 generates a screen request. The screen request includes a login ID. The screen request is information that requests the server device 100 to transmit information necessary to display an algae cultivation screen, which will be described later. After generating the screen request, the processor 310 instructs the communication interface 350 to transmit the screen request to the server device 100. Upon receiving this transmission instruction, the communication interface 350 transmits the screen request to the server device 100. The transmitted screen request is received by the communication interface 150 of the server device 100.

[0051] 3, the processor 110 of the server device 100 determines whether or not a screen request has been received by the communication interface 150. If a screen request has not been received, the processor 110 determines No in step ST11 and proceeds to step ST12.

[0052] In step ST12, processor 110 determines whether or not a purchase request has been received by communication interface 150. If a purchase request has not been received, processor 110 determines No in step ST12 and proceeds to step ST13.

[0053] In step ST13, processor 110 determines whether or not selection information has been received by communication interface 150. If selection information has not been received, processor 110 determines No in step ST13 and proceeds to step ST14.

[0054] In step ST14, the processor 110 determines whether or not a change request has been received by the communication interface 150. If a change request has not been received, the processor 110 determines No in step ST14 and proceeds to step ST15.

[0055] In step ST15, processor 110 determines whether or not to execute point processing. If processor 110 determines not to execute point processing, it determines No in step ST15 and proceeds to step ST16.

[0056] In step ST16, processor 110 determines whether or not result information has been received by communication interface 150. If result information has not been received, processor 110 determines No in step ST16 and returns to step ST11. Thus, processor 110 enters a standby state in which it repeats steps ST11 to ST16 until it receives a screen request, purchase request, selection information, change request, or result information, or determines that point processing will be executed. The purchase request, selection information, change request, point processing, and result information will be described later.

[0057] If a screen request is received while processor 110 is in a standby state where steps ST11 to ST16 are repeated, processor 110 determines Yes in step ST11 and proceeds to step ST17.

[0058] In step ST17, processor 110 refers to user DB 141 to acquire user information identified by the user ID included in the screen request received in step ST11. Processor 110 also acquires the partition ID included in the purchase list information in the user information. Then, processor 110 refers to development DB 142 to acquire partition information associated with each partition ID acquired from the purchase list information.

[0059] In step ST18, the processor 110 generates screen information. The screen information includes information necessary for displaying the algae cultivation screen. The information necessary for displaying the algae cultivation screen includes at least a portion of the user information acquired in step ST17, each partition ID acquired in step ST17, and at least a portion of each partition information acquired in step ST17. After generating the screen information, the processor 110 instructs the communication interface 150 to transmit the screen information to the terminal device 300 that sent the screen request. Upon receiving this transmission instruction, the communication interface 150 transmits the screen information to the terminal device 300. The transmitted screen information is received by the communication interface 350 of the terminal device 300. After processing step ST18, the processor 110 returns to step ST11.

[0060] 5, the processor 310 of the terminal device 300 waits for the screen information to be received by the communication interface 350. If the screen information is received, the processor 310 determines Yes in step ST42 and proceeds to step ST43.

[0061] In step ST43, the processor 310 generates an image corresponding to the algae cultivation screen using the screen information received in ST42. The processor 310 then instructs the display device 370 to display this generated image. Upon receiving the display instruction, the display device 370 displays the algae cultivation screen.

[0062] The algae cultivation screen is, for example, the top screen of the algae cultivation service, and includes, for example, a user information area, a section list area, a quantity input field, and a purchase button.

[0063] The user information area is an area for displaying user information included in the screen information received in step ST42. The user information includes, for example, the number of training points owned by the user.

[0064] The partition list area is an area that displays a list of partitions 222 that the logged-in user has purchased. The partition list area displays information about each partition 222. The partition list area also includes partition selection buttons that correspond to each partition 222 displayed in the partition list area. The partition selection buttons are buttons that the operator operates when instructing the management system 1 to transition to a screen for checking detailed information about the corresponding partition 222 and changing settings for that partition 222.

[0065] The quantity input field is an input field for inputting the number of sections 222 to be newly purchased. The purchase button is a button that the operator operates when instructing the management system 1 to newly purchase the number of sections 222 input in the quantity input field.

[0066] In step ST44, processor 310 determines whether or not to perform processing to purchase section 222. Processor 310 determines to perform processing to purchase section 222 when it receives an instruction to purchase section 222, such as an operation on a purchase button. If processor 310 does not determine to perform processing to purchase section 222, it determines No in step ST44 and proceeds to step ST45.

[0067] In step ST45, processor 310 determines whether any of the section selection buttons has been operated. If any of the section selection buttons has not been operated, processor 310 determines No in step ST45 and returns to step ST44. Thus, processor 310 either determines to perform processing to purchase section 222, or enters a standby state in which steps ST44 and ST45 are repeated until any of the section selection buttons is operated.

[0068] If processor 310 determines to perform processing to purchase section 222 while in a standby state in which steps ST44 and ST45 are repeated, it determines "Yes" in step ST44 and proceeds to step ST46.

[0069] In step ST46, the processor 310 generates a purchase request. The purchase request includes, for example, a login ID and quantity information. The quantity information is the number entered in the quantity input field. The purchase request is information indicating that the number of sections 222 indicated by the quantity information is to be newly purchased. After generating the purchase request, the processor 310 instructs the communication interface 350 to transmit the purchase request to the server device 100. Upon receiving this transmission instruction, the communication interface 350 transmits the purchase request to the server device 100. The transmitted purchase request is received by the communication interface 150 of the server device 100. After processing step ST46, the processor 310 returns to step ST41.

[0070] On the other hand, if a purchase request is received while processor 110 of server device 100 is in a standby state where steps ST11 to ST16 in FIG. 3 are repeated, it determines "Yes" in step ST12 and proceeds to step ST19.

[0071] In step ST19, processor 110 determines which sections 222 to allocate to the user identified by the user ID included in the purchase request received in step ST12. For example, processor 110 determines to allocate to the user the number of sections 222 included in the purchase request from among the sections 222 not allocated to the user. Note that processor 110 checks whether each section 222 has been allocated to the user by, for example, referring to the allocation information in development DB 142.

[0072] In step ST20, the processor 110 performs a payment process for purchasing the section 222. For this payment, various payment methods can be used, such as a credit card, a debit card, electronic money, cryptocurrency, BNPL (buy now, pay later), or a prepaid payment method. Note that it may also be possible to use training points for payment for purchasing the section 222.

[0073] In step ST21, the processor 110 updates the development DB 142 to assign the users who purchased the partitions 222 determined in step ST19 to the partitions 222. That is, the processor 110 associates the user ID included in the purchase request received in step ST12 with the partition ID of each partition 222 determined in step ST19. The processor 110 associates the user ID with the partition ID by writing the user ID in the assignment information associated with the partition ID. After processing step ST21, the processor 110 returns to step ST11.

[0074] If any of the section selection buttons is operated while processor 310 is in a standby state in which steps ST44 and ST45 are repeated, processor 310 determines "Yes" in step ST45 and proceeds to step ST47.

[0075] In step ST47, the processor 310 generates selection information. The selection information includes, for example, a login ID and a selected partition ID. The selected partition ID is the partition ID of the partition 222 corresponding to the operated partition selection button. The selection information is information requesting the transmission of information necessary to display a partition screen, which will be described later. The information necessary to display the partition screen includes information about the partition 222 identified by the selected partition ID. After generating the selection information, the processor 310 instructs the communication interface 350 to transmit the selection information to the server device 100. Upon receiving this transmission instruction, the communication interface 350 transmits the selection information to the server device 100. The transmitted selection information is received by the communication interface 150 of the server device 100.

[0076] On the other hand, if processor 110 of server device 100 receives selection information while in a standby state where steps ST11 to ST16 in FIG. 3 are repeated, it determines Yes in step ST13 and proceeds to step ST22.

[0077] In step ST22, processor 110 acquires information about partition 222 identified by the partition ID included in the selection information received in step ST13. That is, processor 110 refers to growth DB 142 to acquire partition information associated with the partition ID.

[0078] The processor 110 also controls the camera 240 to take an image of the section 222. The processor 110 then acquires the image of the section 222 taken by the camera 240.

[0079] Furthermore, the processor 110 refers to the culture medium DB 143 to acquire the culture medium ID and culture medium information for each culture medium.

[0080] In step ST23, the processor 110 generates partition screen information. The partition screen information includes information necessary for displaying the partition screen. The partition screen information includes, for example, the partition information, image, culture medium ID, and culture medium information acquired in step ST22. After generating the partition screen information, the processor 110 instructs the communication interface 150 to transmit the partition screen information to the terminal device 300 that sent the selection information. Upon receiving this transmission instruction, the communication interface 150 transmits the partition screen information to the terminal device 300. The transmitted partition screen information is received by the communication interface 350 of the terminal device 300. After processing step ST23, the processor 110 returns to step ST11.

[0081] The processor 110 works in cooperation with the communication interface 150 to transmit images of the section 222 to the terminal device 300, thereby functioning as an example of a transmitting unit that transmits images of the cultivation device to the terminal device used by the owner.

[0082] 5, the processor 310 of the terminal device 300 waits for the partition screen information to be received by the communication interface 350. If the partition screen information is received, the processor 310 determines "Yes" in step ST48 and proceeds to step ST49.

[0083] In step ST49, the processor 310 generates an image corresponding to the partition screen using the partition screen information received in ST48. Then, the processor 310 instructs the display device 370 to display this generated image. Upon receiving the display instruction, the display device 370 displays the partition screen.

[0084] The partition screen is a screen that displays details about the partition 222 identified by the selected partition ID. The partition screen includes, for example, a partition information area, a partition image, a culture medium selection area, a culture medium change button, and a back button.

[0085] The partition information area is an area that displays the partition information included in the partition screen information received in step ST48.

[0086] The partition image displays the image included in the partition screen information received in step ST48. Note that the image may be updated in real time. Also, the image may be a real-time moving image.

[0087] The culture solution selection area displays a list of culture solutions that can be used to grow algae, along with a description of each culture solution. The description may include, for example, the name, price, and characteristics of the culture solution. The description may also include the composition of the culture solution. The culture solution selection area allows the user to select a culture solution by operating the input device 360.

[0088] The culture medium change button is a button that is operated when instructing the management system 1 to change the culture medium in the container 221 corresponding to the section 222 whose details are displayed on the section screen to the culture medium selected in the culture medium selection area.

[0089] The back button is a button to be operated when returning from the partition screen to the algae cultivation screen.

[0090] In step ST50, processor 310 determines whether or not the back button has been operated. If the back button has not been operated, processor 310 determines No in step ST50 and proceeds to step ST51.

[0091] In step ST51, processor 310 determines whether or not to change the culture medium. For example, processor 310 determines that the culture medium is to be changed when the culture medium change button is operated while the culture medium is selected in the culture medium selection area. If processor 310 does not determine that the culture medium is to be changed, it determines No in step ST51 and returns to step ST50. Thus, processor 310 enters a standby state in which it repeats steps ST50 and ST51 until the back button is operated or it determines that the culture medium is to be changed.

[0092] If the return button is operated while processor 310 is in a standby state in which steps ST50 and ST51 are repeated, processor 310 determines Yes in step ST50 and returns to step ST41.

[0093] If processor 310 determines that the culture medium is to be changed while in a standby state in which steps ST50 and ST51 are repeated, it determines "Yes" in step ST51 and proceeds to step ST52.

[0094] In step ST52, the processor 310 generates a change request. The change request includes, for example, a login ID, a selected section ID, and a culture medium ID. The culture medium ID is the culture medium ID of the culture medium selected in the culture medium selection area. The change request is information requesting that the culture medium in the container 221 corresponding to the section 222 identified by the selected section ID be changed to the culture medium identified by the culture medium ID. After generating the change request, the processor 310 instructs the communication interface 350 to send the change request to the server device 100. Upon receiving this transmission instruction, the communication interface 350 sends the change request to the server device 100. The sent change request is received by the communication interface 150 of the server device 100. After processing step ST52, the processor 310 returns to step ST50.

[0095] On the other hand, if a change request is received while processor 110 of server device 100 is in a standby state where steps ST11 to ST16 in FIG. 3 are repeated, it determines "Yes" in step ST14 and proceeds to step ST24.

[0096] In step ST24, the processor 110 refers to the culture medium DB 143 and obtains the price associated with the culture medium ID included in the change request received in step ST14. The price indicates the amount of the fee for changing the culture medium. The processor 110 performs payment processing for the amount. Various payment methods can be used for this payment. It is also possible to use cultivation points to pay the fee for changing the culture medium.

[0097] In step ST25, the processor 110 updates the cultivation DB 142 to store the culture medium used in the partition 222 identified by the partition ID included in the change request received in step ST14. That is, the processor 110 changes the culture medium ID in the culture medium information associated with the partition ID to the culture medium ID included in the change request.

[0098] In step ST26, the processor 110 generates change information. The change information includes, for example, the compartment ID included in the change request received in step ST14 and the culture medium ID included in the change request. The change information is information instructing the compartment 222 identified by the compartment ID to be in a state where the culture medium identified by the culture medium ID is contained in the container 221 corresponding to the compartment 222. After generating the change information, the processor 110 instructs the communication interface 150 to transmit the change information to the culture control device 210. Upon receiving this transmission instruction, the communication interface 150 transmits the change information to the culture control device 210. The transmitted change information is received by the communication interface 215 of the culture control device 210. After processing step ST26, the processor 110 returns to step ST11.

[0099] 4, the processor 211 of the culture control device 210 determines whether or not change information has been received by the communication interface 215. If change information has not been received, the processor 211 determines No in step ST31 and proceeds to step ST32.

[0100] In step ST32, the processor 211 determines whether or not a measurement request has been received by the communication interface 215. If a measurement request has not been received, the processor 211 determines No in step ST32 and returns to step ST31. Thus, the processor 211 enters a standby state in which it repeats steps ST31 and ST32 until change information or a measurement request is received. The measurement request will be described later.

[0101] If the processor 211 receives change information while in a standby state in which it repeats steps ST31 and ST32, it determines "Yes" in step ST31 and proceeds to step ST33.

[0102] In step ST33, the processor 211 controls the culture device 220 to put the culture medium identified by the culture medium ID included in the change information received in step ST31 into the container 221. The container 221 is the container 221 corresponding to the partition 222 identified by the partition ID included in the change information. If the container 221 already contains culture medium, the culture device 220 changes the culture medium to the culture medium identified by the culture medium ID. If the container 221 does not contain culture medium, the culture device 220 puts the culture medium identified by the culture medium ID into it. After processing step ST33, the processor 211 returns to step ST31.

[0103] As described above, the server device 100 controls the culture device 220 via the culture control device 210. Therefore, by performing the processes of steps ST14 and ST26, the processor 110 functions as an example of a control unit that determines the composition of the culture solution for cultivating microalgae based on instructions from the owner, and controls the culture device to change the culture solution in the culture device to the composition.

[0104] The processor 110 of the server device 100 executes point processing for each section 222 every time a predetermined time T1 has elapsed. Point processing is a process of awarding points to a user assigned to a section 222 in accordance with the amount of carbon dioxide absorption or growth level of the algae within that section 222. For example, the processor 110 executes point processing for all sections 222 at once. Alternatively, the timing of point processing may differ for each section 222. Note that the timing for point processing is when a predetermined time T1 has elapsed since the previous point processing. The processor 110 determines to execute point processing if it is time to execute point processing for at least one of the sections 222.

[0105] If processor 110 determines to execute the point processing when in a standby state in which steps ST11 to ST16 in FIG. 3 are repeated, it determines Yes in step ST15 and proceeds to step ST27.

[0106] In step ST27, the processor 110 generates a measurement request. The measurement request includes the partition ID of the target for which point processing is to be performed. The partition ID may be one or more. The measurement request is information that instructs measuring the absorbance for the partition ID. After generating the measurement request, the processor 110 instructs the communication interface 150 to send the measurement request to the culture control device 210. Upon receiving this instruction to send, the communication interface 150 sends the measurement request to the culture control device 210. The sent measurement request is received by the communication interface 215 of the culture control device 210. After processing step ST27, the processor 110 returns to step ST11.

[0107] On the other hand, if the processor 211 of the culture control device 210 receives a measurement request while in a standby state where steps ST31 and ST32 in FIG. 4 are repeated, it determines Yes in step ST32 and proceeds to step ST34.

[0108] In step ST34, the processor 211 controls the absorbance measurement device 230 to measure the absorbance of the algal liquid in the container 221. The container 221 in question is the container 221 corresponding to the section 222 identified by the section ID included in the measurement request received in step ST32. If the measurement request includes multiple section IDs, the processor 211 measures the absorbance of the algal liquid in the container 221 for each section ID.

[0109] In step ST35, the processor 211 generates result information. The result information includes each partition ID included in the measurement request received in step ST32 and the measurement results of step ST34 for each partition ID. After generating the result information, the processor 211 instructs the communication interface 215 to transmit the result information to the server device 100. Upon receiving this transmission instruction, the communication interface 215 transmits the result information to the server device 100. The transmitted result information is received by the communication interface 150 of the server device 100. After processing step ST35, the processor 211 returns to step ST31.

[0110] On the other hand, if result information is received while processor 110 of server device 100 is in a standby state where steps ST11 to ST16 in FIG. 3 are repeated, it determines Yes in step ST16 and proceeds to step ST28.

[0111] In step ST28, processor 110 determines points to be awarded for each block ID included in the result information received in step ST16. Processor 110 determines the points using, for example, the amount of carbon dioxide absorbed by the algae (hereinafter referred to as "carbon dioxide absorption amount").

[0112] The amount of carbon dioxide absorbed can be calculated, for example, by the following formula: This is because the amount of carbon dioxide absorbed by the same amount of algae is constant. (Amount of carbon dioxide absorbed [g]) = (algae concentration [g / liter]) × (liquid volume [liter]) × (C / B ratio) (1) Here, the liquid volume is the volume of the algae liquid in section 222. The C / B ratio is an experimental value of the ratio of the amount of carbon dioxide absorbed contained in the biomass. Here, it is an experimental value of the ratio of the amount of carbon dioxide absorbed contained in the algae. The C / B ratio is calculated, for example, from the amount of carbon dioxide fixed and the algae concentration. Therefore, the C / B ratio indicates the ratio of the amount of carbon dioxide fixed that can be absorbed by the microalgae to the mass of the microalgae. Therefore, the value of the C / B ratio indicates the amount of carbon dioxide absorbed that can be absorbed by unit mass (1 g) of microalgae. An example of the value of the C / B ratio is 2.02.

[0113] The algae concentration can be calculated using the following formula: (Algae concentration [g / liter]) = (OD (optical density) value) × (constant C1) (2) Here, the OD value is a value indicating absorbance. The constant C is a constant obtained from a calibration curve of the OD value and algae concentration. One example of the constant C is 0.5. Note that both the algae concentration and the OD value increase in value according to the degree of algae growth. Therefore, both the algae concentration and the OD value indicate the degree of algae growth.

[0114] Processor 110 calculates the number of points to be awarded, for example, using the following formula: (Number of points) = (amount of carbon dioxide absorbed) × (predetermined coefficient C2) (3)

[0115] Since the C / B ratio is a fixed value, the processor 110 may calculate the number of points using the following formula when the liquid volume is fixed. (Number of points) = (algae concentration) × (predetermined coefficient C3) (4)

[0116] Furthermore, equations (1) to (3) can be summarized as follows: (Number of points) = (OD value) × (constant C1) × (liquid volume) × (C / B ratio) × (predetermined coefficient C2) (5)

[0117] The constant C and the C / B ratio in equation (5) are fixed values. Therefore, the processor 110 can simplify the equation for calculating the number of points by omitting at least one of the constant C and the C / B ratio from the equation for calculating the number of points. By simplifying the equation for calculating the number of points, the amount of calculation required to determine the number of points can be reduced. For example, the processor 110 calculates the number of points using the following equation, which omits the constant C and the C / B ratio. (Number of points) = (OD value) × (liquid volume) × (predetermined coefficient C4) (6)

[0118] If the amount of liquid is fixed, the processor 110 may calculate the number of points using the following formula: (Number of points) = (OD value) × (predetermined coefficient C4) (7)

[0119] The processor 110 may calculate the number of points using other formulas, provided that the formula is such that the greater the OD value, algae concentration, or carbon dioxide absorption amount, the greater the number of points.

[0120] The processor 110 may also calculate the number of points using a table. The table is, for example, a table that converts the OD value, algae concentration, or carbon dioxide absorption amount into a number of points. The table is a conversion table in which the number of points increases as the OD value, algae concentration, or carbon dioxide absorption amount increases.

[0121] As described above, processor 110 performs the process of step ST28, thereby functioning as an example of an incentive determination unit that determines the quantity of incentives.

[0122] In step ST29, the processor 110 performs the following process for each partition ID included in the result information received in step ST16. The processor 110 updates the user DB 141 and assigns points to the owner of the partition 222 identified by the partition ID. To do this, the processor 110 identifies the owner of the partition 222 for which points were determined in step ST28. That is, the processor 110 references the development DB 142 and acquires the user ID associated with the partition ID of the partition 222. The user identified by the user ID is the owner. The processor 110 rewrites the point information associated with the user ID in the user DB 141 and increases the points indicated by the point information by the points determined in step ST28. Furthermore, the processor 110 rewrites the partition point information associated with the partition ID in the partition DB 143 and increases the points indicated by the partition point information by the points determined in step ST28. After processing step ST29, the processor 110 returns to step ST11.

[0123] As described above, by performing the process of step ST29, processor 110 functions as an example of a granting unit that grants the amount of incentive determined in step ST28 to the owner of the breeding device.

[0124] The management system 1 of the embodiment cultivates algae using a culture device 220. The management system 1 of the embodiment then awards points to users who are owners of plots 222 in the culture device 220, depending on the amount of carbon dioxide absorbed by the algae or the degree of cultivation. In this way, users who purchase plots 222 can earn points, which is expected to increase the number of people who purchase plots 222. Therefore, the management system 1 of the embodiment is expected to increase the number of owners, i.e., people who participate in algae cultivation.

[0125] The management system 1 of the embodiment also includes a culture device 220. The management system 1 cultivates algae using the culture device 220. Therefore, the user does not need to cultivate the algae himself. Therefore, the user does not need to prepare cultivation equipment. Furthermore, the user does not need to have any knowledge about algae. Therefore, it is believed that the management system 1 of the embodiment can increase the number of owners, i.e., the number of people who participate in algae cultivation.

[0126] The management system 1 of the embodiment also measures the absorbance of the algae liquid. Then, the management system 1 of the embodiment uses the absorbance to calculate at least one of the amount of carbon dioxide absorption by the algae and the algae concentration. Furthermore, the management system 1 of the embodiment uses the amount of carbon dioxide absorption or the algae concentration to determine points to be awarded to the owner of the section 222. In this way, by using the absorbance, the management system 1 of the embodiment can reduce the amount of calculation required to award points.

[0127] Furthermore, the management system 1 of the embodiment allows the owner of the section 222 to determine the composition of the culture solution. Therefore, the owner can increase the amount of algae produced by changing the culture solution. Furthermore, the owner can determine the main use of the algae by changing the culture solution.

[0128] Furthermore, the management system 1 of the embodiment uses a culture medium selected from a plurality of types of culture medium with a predetermined composition. The owner of the section 222 can select a culture medium from among culture mediums with a predetermined composition, so knowledge of the composition of the culture medium is not required.

[0129] Furthermore, the management system 1 of the embodiment is configured to identify the main use of the algae cultivated in each culture solution, so that the owner of the section 222 can easily determine which culture solution to use by checking the use.

[0130] Furthermore, the management system 1 of the embodiment transmits an image of the section 222 to the owner of the section 222. This allows the owner to see the state of the section 222.

[0131] Furthermore, according to the management system 1 of the embodiment, the culture device 220 includes a plurality of compartments 222. Therefore, more people can become owners of the compartments 222.

[0132] The above embodiment can be modified as follows. The management system of the embodiment may be provided with a transmittance measuring device instead of the absorbance measuring device 230. The transmittance measuring device measures the transmittance of the algal liquid in the container 221. The culture control device 210 or the server device 100 calculates the absorbance using the transmittance. The processor 110 calculates the number of points using the absorbance. Note that the transmittance is an example of a physical quantity that indicates the growth level of microalgae. Therefore, the transmittance measuring device is an example of a measuring device that measures a physical quantity that indicates the growth level of microalgae. Furthermore, the transmittance measuring device, and the culture control device 210 or the server device 100 that calculates the absorbance from the transmittance, are examples of measuring devices that measure a physical quantity that indicates the growth level of microalgae.

[0133] The management system of the embodiment may include a concentration measuring device instead of the absorbance measuring device 230. The concentration measuring device measures the algae concentration of the algae liquid in the container 221. The processor 110 calculates the number of points using the algae concentration. Note that the algae concentration is an example of a physical quantity that indicates the growth level of microalgae. Therefore, the concentration measuring device is an example of a measuring device that measures a physical quantity that indicates the growth level of microalgae.

[0134] The period during which a person can become the owner of a parcel 222 by purchasing the parcel 222 may be limited.

[0135] In the above embodiment, the management system 1 grants development points to the user. However, the management system 1 may grant cash, cryptocurrency, securities, or the like instead of development points. In this case, in step ST28, the processor 110 of the server device 100 calculates, for example, the amount of cash, cryptocurrency, or securities instead of the number of points. Each of the cash, cryptocurrency, securities, and the like is an example of an incentive to be granted to the owner of the section 222.

[0136] The culture medium may also be purchased when purchasing the section 222. In this case, if the container 221 corresponding to the section 222 does not contain the culture medium, the management system 1 can fill the container 221 with the culture medium to be purchased without changing the culture medium.

[0137] The server device 100 may also function as the culture control device 210 .

[0138] In the above embodiment, part of the processing performed by the server device 100 may be executed by the culture control device 210 or the terminal device 300. In the above embodiment, part of the processing performed by the culture control device 210 may be executed by the server device 100. In the above embodiment, part of the processing performed by the terminal device 300 may be executed by the server device 100.

[0139] Each device in the embodiment may be made up of multiple devices.

[0140] The processor 110, processor 211, or processor 310 may implement part or all of the processing implemented by a program in the above embodiments by a hardware circuit configuration.

[0141] A program for implementing the processes of the embodiments may be transferred in a state where it is stored in a non-transitory computer-readable storage medium within the device. However, the device may also be transferred without the program stored therein. The program may then be transferred separately and written to the device. In this case, the program may be transferred by, for example, recording it on a removable non-transitory computer-readable storage medium or by downloading it via a network such as the Internet or a LAN.
