Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In each figure, the dimensions and scales of each part are appropriately different from the actual ones. Further, the embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are imposed. However, the scope of the present invention is not limited to these embodiments unless there is a description to specifically limit the present invention in the following description.

[0012] <A. Embodiment> Hereinafter, an embodiment of the present invention will be described.

[0013] <1. Outline of the Currency Processing Device> Hereinafter, the outline of the plant cultivation system Sys will be described with reference to FIGS. 1 to 10.

[0014] FIG. 1 is a block diagram showing an example of the outline of the configuration of the plant cultivation system Sys.

[0015] As illustrated in FIG. 1, the plant cultivation system Sys includes an agricultural greenhouse 1. The agricultural greenhouse 1 is, for example, a facility for cultivating plants such as a plastic greenhouse or a glass greenhouse.

[0016] FIG. 2 is an explanatory diagram showing an example of the appearance of the agricultural greenhouse 1.

[0017] As illustrated in Figure 2, the agricultural greenhouse 1 has an internal space SP for cultivating plants, which is a space partitioned by a plurality of side walls WL-S made of light-transmitting materials such as vinyl, plastic, or glass, and a roof WL-T made of light-transmitting materials such as plastic or glass. The vinyl may be, for example, an agricultural polyolefin film (also called agricultural PO film) or a film made of fluororesin. The agricultural greenhouse 1 also includes, for example, windows WWD provided in the side walls WL-S or roof WL-T, and curtains WCT provided in the side walls WL-S or roof WL-T. Furthermore, although details will be described later, the agricultural greenhouse 1 includes an environmental control system 2 including a ventilation device EY2, an environmental measurement system 3, and a communication device 4.

[0018] Let's return to the explanation in Figure 1. As illustrated in Figure 1, the plant cultivation system Sys comprises a server device 5 and a terminal device 9.

[0019] The server device 5 (an example of an "information processing device") can communicate with the agricultural greenhouse 1 via the network NW and control various devices installed in the agricultural greenhouse 1. Details of the server device 5 will be described later. Terminal device 9 can communicate with server device 5 via network NW and supplies information input from terminal device 9 to server device 5.

[0020] Figure 3 is a block diagram showing an example of the configuration of terminal device 9.

[0021] As illustrated in Figure 3, the terminal device 9 comprises a control device 91 for controlling each part of the terminal device 9, a storage device 92 for storing various information, a display device 93 for displaying various information, an input device 94 for inputting various information, and a communication device 95 for communicating with an external device located outside the terminal device 9.

[0022] The storage device 92 is configured to include, for example, one or both of the following: a volatile memory such as RAM (Random Access Memory) that functions as a work area for the control device 91, and a non-volatile memory such as EEPROM (Electrically Erasable Programmable Read-Only Memory) that stores various information such as the control program for the terminal device 9.

[0023] The control device 91 is configured, for example, to include a processor. The processor provided in the control device 91 is configured, for example, to include one or more CPUs (Central Processing Units). The processor provided in the control device 91 executes the control program for the terminal device 9 stored in the storage device 92 and controls each part of the terminal device 9 by operating according to the control program. In addition to one or more CPUs, the processor provided in the control device 91 may also be configured to include hardware such as a GPU (Graphics Processing Unit), DSP (Digital Signal Processor), or FPGA (Field Programmable Gate Array).

[0024] The communication device 95 is, for example, hardware for communicating with the server device 5 via a network NW. The control device 91 controls the communication device 95 so that information input from the input device 94 is transmitted to the server device 5 via the network NW.

[0025] Figure 4 shows an example of the input screen G1 displayed on the display device 93 when information is input from the terminal device 9. The control device 91 controls the display device 93 so that the input screen G1 is displayed on the display device 93. In this embodiment, it is assumed that the user of the terminal device 9 inputs information about plants to be cultivated in the internal space SP of the agricultural greenhouse 1 from the input device 94, while referring to the input screen G1 displayed on the display device 93.

[0026] As illustrated in Figure 4, the input screen G1 includes input area L11, input area L12, input area L13, input area L14, input area L15, input area L16, and a confirmation button BTN.

[0027] Input area L11 is provided with multiple radio buttons for selecting the types of plants to be cultivated in greenhouse 1. The user of terminal device 9 specifies the types of plants to be cultivated in greenhouse 1 by selecting the desired radio button in input area L11. In this embodiment, the invention is described using an example in which the type of plant to be cultivated in the agricultural greenhouse 1 is specified in the input area L11, but the present invention is not limited to this embodiment. For example, in addition to the type of plant to be cultivated in the agricultural greenhouse 1, it may also be possible to specify the variety of that plant in the input area L11. For example, if "strawberry" is selected as the type of plant to be cultivated in the agricultural greenhouse 1 in the input area L11, it may also be possible to set the variety of that plant, such as "Amaou" (registered trademark) or "Tochiotome" (registered trademark), in the input area L11.

[0028] Input area L12 is provided with an input field for inputting, for example, the quantity of plants to be cultivated in agricultural greenhouse 1. The user of terminal device 9 specifies the quantity of plants to be cultivated in agricultural greenhouse 1 by entering the desired number in the input field provided in input area L12.

[0029] Input area L13 is provided with an input field for inputting, for example, the size of the agricultural greenhouse 1. Here, the size of the agricultural greenhouse 1 may be, for example, the area and / or volume of the internal space SP of the agricultural greenhouse 1. The user of the terminal device 9 specifies the size of the agricultural greenhouse 1 by entering a desired numerical value in the input field provided in input area L13. In this embodiment, the plant cultivation system Sys is described as having one agricultural greenhouse 1, but the present invention is not limited to this embodiment. The plant cultivation system Sys may have multiple agricultural greenhouses 1. In this case, for example, it may be possible to input information in the input area L13 to specify one agricultural greenhouse 1 from among the multiple agricultural greenhouses 1 that the plant cultivation system Sys has.

[0030] Input area L14 is provided with multiple radio buttons for selecting one cultivation mode as the main cultivation mode (an example of "one cultivation mode") from among several cultivation modes related to plant cultivation in the agricultural greenhouse 1. Here, cultivation mode refers to controlling various devices installed in the agricultural greenhouse 1 so that plant cultivation in the agricultural greenhouse 1 is carried out according to a desired cultivation policy.

[0031] In this embodiment, we assume, as an example, that the multiple cultivation modes that can be adopted in the plant cultivation system Sys include a quality-priority mode, a cost-priority mode, and a balanced mode. The user of the terminal device 9 can select the quality-priority mode, the cost-priority mode, or the balanced mode as the main cultivation mode.

[0032] Here, the quality-priority mode (an example of the "first cultivation mode") is a cultivation mode in which plants are cultivated in agricultural greenhouse 1 based on a cultivation policy that prioritizes the high quality of the plants cultivated in agricultural greenhouse 1 over the low cost of cultivating plants in agricultural greenhouse 1. Furthermore, the cost-prioritizing mode (an example of the "second cultivation mode") is a cultivation mode in which plants are cultivated in agricultural greenhouse 1 based on a cultivation policy that prioritizes low costs required for cultivating plants in agricultural greenhouse 1 over high quality of plants cultivated in agricultural greenhouse 1. Furthermore, Balance Mode (an example of a "third cultivation mode") is a cultivation mode in which plants are cultivated in Agricultural Greenhouse 1 based on a cultivation policy that aims to achieve both high quality of plants grown in Agricultural Greenhouse 1 and low costs required for plant cultivation in Agricultural Greenhouse 1.

[0033] The input area L15 is provided with multiple radio buttons for selecting, for example, another cultivation mode from among several cultivation modes as a secondary cultivation mode (an example of "another cultivation mode"). The user of the terminal device 9 can select a cultivation mode different from the main cultivation mode as the secondary cultivation mode, from among the quality priority mode, cost priority mode, or balance mode. Alternatively, the user of the terminal device 9 can choose not to select any cultivation mode as the secondary cultivation mode. In this embodiment, as an example, it is assumed that the user of the terminal device 9 can select a secondary cultivation mode after selecting the main cultivation mode.

[0034] In this embodiment, if the user of the terminal device 9 does not select any cultivation mode as a secondary cultivation mode, the cultivation mode selected as the primary cultivation mode from among the multiple cultivation modes will be adopted as the cultivation mode for plant cultivation in the agricultural greenhouse 1. Furthermore, in this embodiment, if the user of the terminal device 9 selects a secondary cultivation mode, a combined cultivation mode, which is a combination of the primary cultivation mode and the secondary cultivation mode, is adopted as the cultivation mode for plant cultivation in the agricultural greenhouse 1. Here, a combined cultivation mode (an example of "two or more cultivation modes") is a cultivation mode that prioritizes the cultivation policy related to the primary cultivation mode while also taking into consideration the cultivation policy related to the secondary cultivation mode.

[0035] In the following, the combined cultivation mode in which quality-priority mode is selected as the primary cultivation mode and cost-priority mode is selected as the secondary cultivation mode will be referred to as the "quality-focused combined cultivation mode." In addition, hereinafter, when the cost - priority mode is selected as the main cultivation mode and the quality - priority mode is selected as the sub - cultivation mode, the combined cultivation mode will be referred to as the "cost - focused combined cultivation mode". In addition, hereinafter, when the quality - priority mode is selected as the main cultivation mode and the balance mode is selected as the sub - cultivation mode, and when the balance mode is selected as the main cultivation mode and the quality - priority mode is selected as the sub - cultivation mode, the combined cultivation modes will also be regarded as the quality - focused combined cultivation modes. In addition, hereinafter, when the cost - priority mode is selected as the main cultivation mode and the balance mode is selected as the sub - cultivation mode, and when the balance mode is selected as the main cultivation mode and the cost - priority mode is selected as the sub - cultivation mode, the combined cultivation modes will also be regarded as the cost - focused combined cultivation modes.

[0036] An input field for inputting the main cultivation mode priority ACY is provided in the input area L16. Here, the main cultivation mode priority ACY is an index value indicating how much the main cultivation mode takes precedence over the sub - cultivation mode when the main cultivation mode is selected in the input area L14 and the sub - cultivation mode is selected in the input area L = 15. More specifically, the main cultivation mode priority ACY is the ratio of the priority of the main cultivation mode based on the priority of the sub - cultivation mode. In other words, in the combined cultivation mode, the main cultivation mode is prioritized "ACY times" more than the sub - cultivation mode. In this embodiment, the main cultivation mode priority ACY is a real number satisfying "1 < ACY". The user of the terminal device 9 specifies the main cultivation mode priority ACY by inputting a desired numerical value in the input field provided in the input area L16.

[0037] The confirmation button BTN is used to confirm the information entered on the input screen G1. When the user of the terminal device 9 selects the confirmation button BTN, the control device 91 controls the communication device 95 so that the information entered on the input screen G1 is sent to the server device 5 as cultivation target information JT. Further details about cultivation target information JT will be described later.

[0038] Figure 5 is a block diagram showing an example of the configuration of agricultural greenhouse 1.

[0039] As illustrated in Figure 5, the agricultural greenhouse 1 includes, as described above, an environmental control system 2 and an environmental measurement system 3. Furthermore, as described above, the agricultural greenhouse 1 includes a communication device 4, which is hardware for communicating with the server device 5 via a network NW.

[0042] The internal environment adjustment system 21 is a system that adjusts the environment of the internal space SP without using the environment of the external space SO. Specifically, in this embodiment, the internal environment adjustment system 21 includes a heating device EX1, a cooling device EX2, a humidifier EX3, a dehumidifier EX4, a carbon dioxide supply device EX5, and a lighting device EX6. Here, the external space SO is the space outside the agricultural greenhouse 1, and is the space in the vicinity of agricultural greenhouse 1 located within a predetermined distance from agricultural greenhouse 1. In the following, the environment of the internal space SP will be referred to as the "internal environment," and the environment of the external space SO will be referred to as the "external environment."

[0043] The heating device EX1 is a device that raises the temperature of the internal space SP by supplying air that is hotter than the temperature of the internal space SP. In the following, the temperature of the air in the internal space SP will be referred to as "internal temperature AN1". The cooling unit EX2 is a device that lowers the internal temperature AN1 by supplying air at a lower temperature than the internal temperature AN1 to the internal space SP.

[0044] The humidifier EX3 is a device that increases the humidity of the internal space SP by humidifying the air within SP. Hereafter, the humidity of the air in the internal space SP will be referred to as "internal humidity AN2". The EX4 dehumidifier is a device that reduces the humidity of the internal space SP by dehumidifying the air in the internal space SP.

[0045] The carbon dioxide supply device EX5 is a device that increases the carbon dioxide concentration in the internal space SP by supplying carbon dioxide to the internal space SP. In the following, the carbon dioxide concentration in the air of the internal space SP will be referred to as "internal carbon dioxide concentration AN3".

[0046] The EX6 lighting device increases the illuminance of the interior space SP by projecting light onto the plants being cultivated in the interior space SP. Hereafter, the illuminance of the interior space SP will be referred to as "interior illuminance AN4".

[0047] Note that internal temperature AN1, internal humidity AN2, internal carbon dioxide concentration AN3, and internal illuminance AN4 are examples of "physical quantities related to the internal environment." In the following, internal temperature AN1, internal humidity AN2, internal carbon dioxide concentration AN3, and internal illuminance AN4 may be collectively referred to as "individual internal environment values ​​ANw." Also, in the following, the heating system EX1, cooling system EX2, humidifier EX3, dehumidifier EX4, carbon dioxide supply system EX5, and lighting system EX6 may be collectively referred to as "internal environment adjustment devices EX."

[0048] The inter-environmental adjustment system 22 is a system that adjusts the internal environment by utilizing the external environment. Specifically, the inter-environmental adjustment system 22 is a system that adjusts the internal environment by changing the relationship between the external environment and the internal environment. Specifically, in this embodiment, the inter-environmental adjustment system 22 includes a window opening device EY1, a ventilation device EY2, and a light-shielding device EY3.

[0049] The window opening device EY1 is a device that opens the window WWD installed in the agricultural greenhouse 1 to bring air from the external space SO into the internal space SP, and to discharge the air from the internal space SP back into the external space SO. By opening the window WWD, the window opening device EY1 can bring the temperature of the air in the internal space SP closer to the temperature of the air in the external space SO, bring the humidity of the air in the internal space SP closer to the humidity of the air in the external space SO, and bring the carbon dioxide concentration in the air in the internal space SP closer to the carbon dioxide concentration in the air in the external space SO.

[0050] In the following, the temperature of the air in the external SO space will be referred to as "external temperature AG1". Furthermore, the humidity of the air in the external SO space will be referred to as "external humidity AG2". Finally, the carbon dioxide concentration in the air in the external SO space will be referred to as "external carbon dioxide concentration AG3".

[0051] The ventilation device EY2 is a device for taking in air from the external space SO into the internal space SP and for discharging air from the internal space SP back into the external space SO. When the ventilation device EY2 is in operation, the temperature of the air in the internal space SP can be brought closer to the temperature of the air in the external space SO, the humidity of the air in the internal space SP can be brought closer to the humidity of the air in the external space SO, and the carbon dioxide concentration in the air in the internal space SP can be brought closer to the carbon dioxide concentration in the air in the external space SO. In this embodiment, it is assumed that the air intake efficiency of the ventilation device EY2 from the external space SO is higher than the air intake efficiency of the window opening device EY1 from the external space SO. Also, in this embodiment, it is assumed that the air discharge efficiency of the ventilation device EY2 from the internal space SP is higher than the air discharge efficiency of the window opening device EY1 from the internal space SP.

[0052] The shading device EY3 is a device that reduces the influence of the illuminance of the external space SO on the illuminance of the internal space SP by closing the curtain WCT installed in the agricultural greenhouse 1. Specifically, the shading device EY3 reduces the amount of sunlight irradiated into the internal space SP via the external space SO by closing the curtain WCT installed in the agricultural greenhouse 1, thereby lowering the internal illuminance AN4 and the internal temperature AN1. In the following, the illuminance of the external space SO will be referred to as "external illuminance AG4".

[0053] Note that external temperature AG1, external humidity AG2, external carbon dioxide concentration AG3, and external illuminance AG4 are examples of "physical quantities related to the external environment." In the following, external temperature AG1, external humidity AG2, external carbon dioxide concentration AG3, and external illuminance AG4 may be collectively referred to as "individual external environmental values ​​AGw." Also, in the following, window opening device EY1, ventilation device EY2, and shading device EY3 may be collectively referred to as "environmental adjustment devices EY."

[0054] Furthermore, in the following, the internal environment control device EX and the inter-environment control device EY may be collectively referred to as "environment control device E".

Specifically, in this embodiment, the internal environment measurement system 31 includes an internal environment temperature sensor SX1, an internal environment humidity sensor SX2, an internal environment carbon dioxide concentration sensor SX3, and an internal environment illuminance sensor SX4.

[0058] The internal ambient temperature sensor SX1 detects the internal temperature AN1 and supplies the internal ambient temperature information JN1, which indicates the detection result, to the server device 5 via the communication device 4. The internal environment humidity sensor SX2 detects the internal humidity AN2 and supplies the internal environment humidity information JN2, which indicates the detection result, to the server device 5 via the communication device 4.

[0065] The storage device 7 is configured to include, for example, one or both of the following: a volatile memory such as RAM that functions as a work area for the control device 6, and a non-volatile memory such as EEPROM that stores various information such as the control program PG of the server device 5 (see Figure 10, described later). The control device 6 is configured, for example, to include a processor. The processor provided in the control device 6 is configured, for example, to include one or more CPUs.

The device control unit 64 controls the environmental adjustment system 2 based on the determination result by the device determination unit 63. That is, the device control unit 64 controls the multiple environmental adjustment devices E of the environmental adjustment system 2 according to one or more cultivation modes selected as the main cultivation mode or sub-cultivation mode from among the multiple cultivation modes.

Here, the variable k is a natural number satisfying "1≦k≦K".

[0072] <2. Operation of Server Device 5> The operation of the server device 5 when it performs plant cultivation adjustment processing will be described below with reference to Figures 11 to 30.

[0073] Figures 11 and 12 are flowcharts illustrating an example of the operation of the server device 5 when it performs plant cultivation adjustment processing.

[0074] As illustrated in Figure 11, when the plant cultivation adjustment process is started, the cultivation target information acquisition unit 611 provided in the server device 5 acquires cultivation target information JT from the terminal device 9 (S101) and stores the acquired cultivation target information JT in the storage device 7.

[0075] Figure 13 shows an example of the data structure of the cultivation target information JT. Here, the cultivation target information JT is information that shows the content entered from the input screen G1 displayed on the display device 93 of the terminal device 9.

[0076] As illustrated in Figure 13, the cultivation target information JT includes cultivation target plant information JT1, cultivation target plant quantity information JT2, greenhouse size information JT3, and selection mode information JC.

[0077] The plant information JT1 refers to information indicating the plant ID corresponding to the type of plant entered in input area L11 of input screen G1. Here, the plant ID is information used to identify each type of plant from among the one or more types of plants that can be cultivated in agricultural greenhouse 1. The cultivation target plant quantity information JT2 refers to information indicating the quantity of plants entered in the input area L12 of the input screen G1. Greenhouse size information JT3 is information indicating the size of agricultural greenhouse 1, entered from input area L13 on input screen G1.

[0078] The selected mode information JC (an example of "selected information") includes the primary cultivation mode information JC1, the secondary cultivation mode information JC2, and the primary cultivation mode priority information JCY.

[0079] The primary cultivation mode information JC1 refers to information indicating the cultivation mode ID of the cultivation mode selected as the primary cultivation mode. Here, the cultivation mode ID is information used to identify each cultivation mode from among the multiple cultivation modes that can be adopted in the plant cultivation system Sys, excluding the combined cultivation mode. In other words, the cultivation mode ID is information used to identify each cultivation mode from among the quality-priority mode, cost-priority mode, and balance mode.

[0080] The secondary cultivation mode information JC2 indicates the cultivation mode ID of the cultivation mode selected as the secondary cultivation mode. If no cultivation mode is selected as the secondary cultivation mode, the secondary cultivation mode information JC2 will be set to a value other than the cultivation mode ID, such as a null value. The primary cultivation mode priority information JCY refers to the information indicating the primary cultivation mode priority ACY mentioned above.

[0081] As illustrated in Figure 11, in the plant cultivation adjustment process, the target value information acquisition unit 612 provided in the server device 5 acquires the target value information JPP contained in the plant cultivation information JP stored in the storage device 7 (S103).

[0082] Figure 14 shows an example of the data structure of Plant Cultivation Information JP. Here, Plant Cultivation Information JP is information about plants that can be cultivated in agricultural greenhouse 1.

[0083] As illustrated in Figure 14, the plant cultivation information JP has one or more records that correspond one or more types of plants that can be cultivated in the agricultural greenhouse 1 on a one-to-one basis. Each record in the plant cultivation information JP has a plant ID, plant name information, and target value information JPP.

[0084] Of these, plant name information refers to information indicating the name of the plant corresponding to the plant ID recorded in each record. Furthermore, the target value information JPP is information that indicates the target individual internal environmental value ANw when cultivating a plant corresponding to a plant ID in the agricultural greenhouse 1. Specifically, in this embodiment, the target value information JPP includes temperature target value information JP1, humidity target value information JP2, carbon dioxide concentration target value information JP3, and illuminance target value information JP4.

[0085] The temperature target value information JP1 is information that indicates the target temperature AP1, which is the internal temperature AN1 that should be targeted when cultivating the plant corresponding to the plant ID. Humidity target value information JP2 is information that indicates the target humidity AP2, which is the internal humidity AN2 that should be targeted when cultivating the plant corresponding to the plant ID. The carbon dioxide concentration target value information JP3 is information that indicates the target carbon dioxide concentration AP3, which is the internal carbon dioxide concentration AN3 that should be targeted when cultivating the plant corresponding to the plant ID. Illuminance target value information JP4 is information that indicates the target illuminance AP4, which is the target internal illuminance AN4 when cultivating the plant corresponding to the plant ID.

[0086] In the following, target temperature AP1, target humidity AP2, target carbon dioxide concentration AP3, and target illuminance AP4 may be collectively referred to as "individual target value APw." Similarly, temperature target value information JP1, humidity target value information JP2, carbon dioxide concentration target value information JP3, and illuminance target value information JP4 may be collectively referred to as "individual target value information JPw." Here, individual target value information JPw is information indicating an individual target value APw (an example of a "target value").

[0087] In this embodiment, an example is given in which the individual target value APw is determined as a fixed value according to the type of plant cultivated in the agricultural greenhouse 1, but the present invention is not limited to this embodiment. For example, the individual target value APw may be set to a value that fluctuates according to the growth stage of the plants cultivated in agricultural greenhouse 1. Alternatively, for example, the individual target value APw may be set to a value that fluctuates according to either or both of the season and time of day in which the plants are cultivated in agricultural greenhouse 1. Alternatively, for example, the individual target value APw may be set to a value corresponding to one or more cultivation modes indicated by the selected mode information JC.

[0088] In this embodiment, in step S103, the target value information acquisition unit 612 acquires, from among a plurality of target value information JPP included in the plant cultivation information JP stored in the storage device 7, the target value information JPP corresponding to the plant ID indicated by the cultivation target plant information JT1 included in the cultivation target information JT acquired in step S101.

[0089] As illustrated in Figure 11, in the plant cultivation adjustment process, the internal environment adjustment device information acquisition unit 614 provided in the server device 5 acquires the internal environment adjustment device information JX stored in the storage device 7 (S105).

[0090] Figure 15 shows an example of the data structure of the internal environment control device information JX. Here, the internal environment control device information JX refers to information about the internal environment control device EX.

[0091] As illustrated in Figure 15, the internal environment control device information JX has multiple records that correspond one-to-one with multiple internal environment control devices EX present in the agricultural greenhouse 1. Each record of the internal environment control device information JX includes an internal device ID, internal device name information, operating cost information JXC, and internal environment correction capability information JXX.

[0092] The internal device ID is information used to identify each internal environmental control device EX from among all internal environmental control devices EX present in agricultural greenhouse 1. Internal device name information refers to information indicating the name of each internal environmental control device EX.

[0093] The operating cost information JXC is information that indicates the cost CX incurred when the internal environment control device EX is in operation. Here, cost CX may be, for example, the amount of electricity consumed per unit time when the internal environment control device EX is in operation, or the amount of money incurred per unit time when the internal environment control device EX is in operation.

[0094] In this embodiment, as an example, we assume that cost CX is a predetermined fixed value. Specifically, in this embodiment, as an example, we assume that the cost CX1 of the heating device EX1 is "10", the cost CX2 of the cooling device EX2 is "10", the cost CX3 of the humidifier EX3 is "8", the cost CX4 of the dehumidifier EX4 is "8", the cost CX5 of the carbon dioxide supply device EX5 is "6", and the cost CX6 of the lighting device EX6 is "6". However, the present invention is not limited to these embodiments. For example, cost CX may be a value that fluctuates according to the quantity of plants indicated by the quantity information of plants to be cultivated JT2. Alternatively, for example, cost CX may be a value that fluctuates according to the size of the agricultural greenhouse 1 indicated by the greenhouse size information JT3. Alternatively, for example, cost CX may be a value that fluctuates according to the individual internal environment value ANw indicated by the individual internal environment information JNw.

[0095] Internal environment correction capability information JXX is information indicating the ability of the internal environment adjustment device EX to correct individual internal environment values ​​ANw. Specifically, in this embodiment, internal environment correction capability information JXX includes temperature rise capability information JX1, temperature fall capability information JX2, humidity rise capability information JX3, humidity fall capability information JX4, carbon dioxide concentration rise capability information JX5, and illuminance rise capability information JX6.

[0096] Temperature rise capability information JX1 refers to information indicating the temperature rise capability AX1, which is the ability of the internal environment control device EX to raise the internal temperature AN1. The temperature reduction capability information JX2 is information indicating the temperature reduction capability AX2, which is the ability of the internal environment control device EX to reduce the internal temperature AN1. In this embodiment, as an example, it is assumed that the temperature reduction capability AX2 is the value obtained by multiplying the temperature increase capability AX1 by "-1".

[0097] Humidity increase capacity information JX3 indicates the humidity increase capacity AX3, which is the ability of the internal environment control device EX to increase the internal humidity AN2. The humidity reduction capacity information JX4 is information indicating the humidity reduction capacity AX4, which is the ability of the internal environment control device EX to reduce the internal humidity AN2. In this embodiment, as an example, it is assumed that the humidity reduction capacity AX4 is the value obtained by multiplying the humidity increase capacity AX3 by "-1".

[0098] The carbon dioxide concentration increase capacity information JX5 indicates the carbon dioxide concentration increase capacity AX5, which is the ability of the internal environment adjustment device EX to increase the internal carbon dioxide concentration AN3. Illuminance increase capability information JX6 indicates the illuminance increase capability AX6, which is the ability of the internal environment control device EX to increase the internal illuminance AN4.

[0099] In the following, the temperature rise capability information JX1, temperature fall capability information JX2, humidity rise capability information JX3, humidity fall capability information JX4, carbon dioxide concentration rise capability information JX5, and illuminance rise capability information JX6 may be collectively referred to as "physical quantity correction capability information JXz." Also, in the following, the temperature rise capability AX1, temperature fall capability AX2, humidity rise capability AX3, humidity fall capability AX4, carbon dioxide concentration rise capability AX5, and illuminance rise capability AX6 may be collectively referred to as "physical quantity correction capability AXz." In other words, physical quantity correction capability information JXz is information that indicates the physical quantity correction capability AXz.

[0100] Furthermore, in this embodiment, it is assumed that when the physical quantity correction capability AXz indicated by the internal environment adjustment device EX is a positive value, the internal environment adjustment device EX has the physical quantity correction capability AXz; when the physical quantity correction capability AXz indicated by the internal environment adjustment device EX is "0", the internal environment adjustment device EX does not have the physical quantity correction capability AXz; and when the physical quantity correction capability AXz indicated by the internal environment adjustment device EX is a negative value, the internal environment adjustment device EX has the capability opposite to the physical quantity correction capability AXz.

[0101] As shown in Figure 15, in this embodiment, as an example, we assume that the physical quantity correction capacity AXz is a predetermined fixed value. Specifically, in this embodiment, as an example, we assume that for the heating device EX1, the temperature rise capacity AX1 is "5", that is, the temperature fall capacity AX2 is "-5", and the humidity fall capacity AX4 is "2", that is, the humidity rise capacity AX3 is "-2". Also in this embodiment, as an example, we assume that for the cooling device EX2, the temperature fall capacity AX2 is "5", that is, the temperature rise capacity AX1 is "-5", and the humidity rise capacity AX3 is "2", that is, the humidity fall capacity AX4 is "-2". Also in this embodiment, as an example, we assume that for the humidifier EX3, the humidity rise capacity AX3 is "5", that is, the humidity fall capacity AX4 is "-5". Also in this embodiment, as an example, we assume that for the dehumidifier EX4, the humidity fall capacity AX4 is "5", that is, the humidity rise capacity AX3 is "-5". Furthermore, in this embodiment, as an example, we assume that the carbon dioxide supply device EX5 has a carbon dioxide concentration increase capacity AX5 of "5". Also, in this embodiment, as an example, we assume that the lighting device EX6 has an illuminance increase capacity AX6 of "5". However, the present invention is not limited to these embodiments. For example, the physical quantity correction capacity AXz may be a value that varies according to the quantity of plants indicated by the quantity information of cultivated plants JT2. Alternatively, for example, the physical quantity correction capacity AXz may be a value that varies according to the size of the agricultural greenhouse 1 indicated by the greenhouse size information JT3. Alternatively, for example, the physical quantity correction capacity AXz may be a value that varies according to the individual internal environment value ANw indicated by the individual internal environment information JNw.

[0102] As illustrated in Figure 11, in the plant cultivation adjustment process, the mode-related information acquisition unit 613 provided in the server device 5 acquires the mode-related information JM stored in the storage device 7 (S107).

[0103] Figure 16 shows an example of the data structure of mode-related information JM. Here, mode-related information JM refers to information about each cultivation mode.

[0104] As illustrated in Figure 16, the mode-related information JM has multiple records (three records in this embodiment) that correspond one-to-one with multiple cultivation modes, excluding the combined cultivation mode, from among the multiple cultivation modes that can be adopted in the plant cultivation system Sys. Each record of the mode-related information JM includes a cultivation mode ID, cultivation mode name information, reference value information JRR, and tolerance value information JLL.

[0105] Cultivation mode name information refers to information indicating the name of the cultivation mode corresponding to the cultivation mode ID.

[0106] Reference value information JRR is information that includes temperature reference value information JR1, humidity reference value information JR2, carbon dioxide concentration reference value information JR3, and illuminance reference value information JR4, and defines the environmental reference range for each cultivation mode. Here, the environmental reference range is the range of individual internal environmental values ​​ANw in which the individual internal environmental value ANw indicated by the individual internal environmental information JNw and the individual target value APw indicated by the individual target value information JPw can be considered to be equal in the cultivation of plants in each cultivation mode.

[0107] Specifically, in this embodiment, the internal temperature AN1 is considered to be within the environmental reference range if the difference between the internal temperature AN1 and the target temperature AP1 is less than or equal to the temperature reference value AR1 indicated by the temperature reference value information JR1 included in the reference value information JRR. Furthermore, if the difference between the internal humidity AN2 and the target humidity AP2 is less than or equal to the humidity reference value AR2 indicated by the humidity reference value information JR2 included in the reference value information JRR, then the internal humidity AN2 will be considered to be within the environmental reference range. Furthermore, if the difference between the internal carbon dioxide concentration AN3 and the target carbon dioxide concentration AP3 is less than or equal to the carbon dioxide concentration standard value AR3 indicated by the carbon dioxide concentration standard value information JR3 included in the standard value information JRR, then the internal carbon dioxide concentration AN3 will be considered to be within the environmental standard range. Furthermore, if the difference between the internal illuminance AN4 and the target illuminance AP4 is less than or equal to the illuminance reference value AR4 indicated in the illuminance reference value information JR4 included in the reference value information JRR, then the internal illuminance AN4 will be considered to be within the environmental reference range.

[0108] In the following, the temperature reference value AR1, humidity reference value AR2, carbon dioxide concentration reference value AR3, and illuminance reference value AR4 may be collectively referred to as "individual reference value ARw." Also, in the following, the temperature reference value information JR1, humidity reference value information JR2, carbon dioxide concentration reference value information JR3, and illuminance reference value information JR4 may be collectively referred to as "individual reference value information JRw." Here, individual reference value information JRw is information that indicates the individual reference value ARw (an example of the "first threshold"). Thus, in this embodiment, the individual internal environmental value ANw is included in the environmental reference range when the difference between the individual internal environmental value ANw and the individual target value APw is less than or equal to the individual reference value ARw indicated by the individual reference value information JRw.

[0109] In this embodiment, as an example, we assume that the individual reference value ARw is a fixed value predetermined according to the cultivation mode. Specifically, in this embodiment, as an example, we assume that the individual reference value ARw related to the quality priority mode is smaller than the individual reference value ARw related to the balance mode, and that the individual reference value ARw related to the balance mode is smaller than the individual reference value ARw related to the cost priority mode. However, the present invention is not limited to these embodiments. For example, the individual reference value ARw may be a value that fluctuates according to the individual internal environment value ANw indicated by the individual internal environment information JNw.

[0110] Tolerance information JLL is information that includes temperature tolerance information JL1, humidity tolerance information JL2, carbon dioxide concentration tolerance information JL3, and illuminance tolerance information JL4, and defines the environmental tolerance range for each cultivation mode. Here, the environmental tolerance range is the range of individual internal environmental values ​​ANw in which, in the cultivation of plants in each cultivation mode, it can be considered that there is no impediment to plant growth even without modifying the individual internal environmental values ​​ANw indicated by the individual internal environmental information JNw.

[0111] Specifically, in this embodiment, the internal temperature AN1 is considered to be within the environmental tolerance range if the difference between the internal temperature AN1 and the target temperature AP1 is less than or equal to the temperature tolerance value AL1 indicated by the temperature tolerance value information JL1 included in the tolerance value information JLL. Furthermore, if the difference between the internal humidity AN2 and the target humidity AP2 is less than or equal to the humidity tolerance value AL2 indicated in the humidity tolerance value information JL2 included in the tolerance value information JLL, then the internal humidity AN2 is considered to be within the environmental tolerance range. Furthermore, if the difference between the internal carbon dioxide concentration AN3 and the target carbon dioxide concentration AP3 is less than or equal to the carbon dioxide concentration tolerance value AL3 indicated in the carbon dioxide concentration tolerance value information JL3 included in the tolerance value information JLL, then the internal carbon dioxide concentration AN3 will be considered to be within the environmental tolerance range. Furthermore, in this embodiment, internal illuminance AN4 is considered to be within the environmental tolerance range if the difference between internal illuminance AN4 and target illuminance AP4 is less than or equal to the illuminance tolerance value AL4 indicated by the illuminance tolerance value information JL4 included in the tolerance value information JLL.

[0112] In the following, the temperature tolerance value AL1, humidity tolerance value AL2, carbon dioxide concentration tolerance value AL3, and illuminance tolerance value AL4 may be collectively referred to as "individual tolerance value ALw." Also, in the following, the temperature tolerance value information JL1, humidity tolerance value information JL2, carbon dioxide concentration tolerance value information JL3, and illuminance tolerance value information JL4 may be collectively referred to as "individual tolerance value information JLw." Here, individual tolerance value information JLw is information indicating the individual tolerance value ALw (an example of a "second threshold"). Thus, in this embodiment, if the difference between the individual internal environmental value ANw and the individual target value APw is less than or equal to the individual tolerance value ALw indicated by the individual tolerance value information JLw, the individual internal environmental value ANw is included in the environmental tolerance range.

[0113] In this embodiment, as an example, we assume that the individual tolerance value ALw is a fixed value predetermined according to the cultivation mode. Specifically, in this embodiment, as an example, we assume that the individual tolerance value ALw related to the quality priority mode is smaller than the individual tolerance value ALw related to the balance mode, and that the individual tolerance value ALw related to the balance mode is smaller than the individual tolerance value ALw related to the cost priority mode. However, the present invention is not limited to these embodiments. For example, the individual tolerance value ALw may be a value that varies according to the individual internal environment value ANw indicated by the individual internal environment information JNw.

[0114] In this embodiment, as illustrated in Figure 16, the individual tolerance value ALw corresponding to one cultivation mode is set to a value greater than the individual reference value ARw corresponding to one cultivation mode. In other words, the temperature tolerance value AL1 corresponding to one cultivation mode is set to a value greater than the temperature standard value AR1 corresponding to one cultivation mode. Also, in this embodiment, the humidity tolerance value AL2 corresponding to one cultivation mode is set to a value greater than the humidity standard value AR2 corresponding to one cultivation mode. Also, in this embodiment, the carbon dioxide concentration tolerance value AL3 corresponding to one cultivation mode is set to a value greater than the carbon dioxide concentration standard value AR3 corresponding to one cultivation mode. Also, in this embodiment, the illuminance tolerance value AL4 corresponding to one cultivation mode is set to a value greater than the illuminance standard value AR4 corresponding to one cultivation mode.

[0115] As illustrated in Figure 11, in the plant cultivation adjustment process, the internal environment information acquisition unit 615 provided in the server device 5 acquires internal environment information JN from the internal environment measurement system 31 (S109) and stores the acquired internal environment information JN in the storage device 7.

[0116] Figure 17 shows an example of the data structure of the internal environment information JN.

[0117] As illustrated in Figure 17, the internal environment information JN includes internal environment temperature information JN1, which indicates the internal temperature AN1 detected by the internal environment temperature sensor SX1; internal environment humidity information JN2, which indicates the internal humidity AN2 detected by the internal environment humidity sensor SX2; internal environment carbon dioxide concentration information JN3, which indicates the internal carbon dioxide concentration AN3 detected by the internal environment carbon dioxide concentration sensor SX3; and internal environment illuminance information JN4, which indicates the internal illuminance AN4 detected by the internal environment illuminance sensor SX4. In other words, the internal environment information JN is information indicating the individual internal environment value ANw detected by the internal environment measurement system 31.

[0118] As illustrated in Figure 11, in the plant cultivation adjustment process, the external environmental information acquisition unit 616 provided in the server device 5 acquires external environmental information JG from the external environmental measurement system 32 (S111), and stores the acquired external environmental information JG in the storage device 7.

[0119] Figure 18 shows an example of the data structure of the external environment information JG.

[0120] As illustrated in Figure 18, the external environmental information JG (an example of "external information") includes external environmental temperature information JG1, which shows the external temperature AG1 detected by the external environmental temperature sensor SY1; external environmental humidity information JG2, which shows the external humidity AG2 detected by the external environmental humidity sensor SY2; external environmental carbon dioxide concentration information JG3, which shows the external carbon dioxide concentration AG3 detected by the external environmental carbon dioxide concentration sensor SY3; and external environmental illuminance information JG4, which shows the external illuminance AG4 detected by the external environmental illuminance sensor SY4. In other words, the external environmental information JG is information that shows the individual external environmental value AGw detected by the external environmental measurement system 32.

[0121] As illustrated in Figure 11, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 identifies an unacceptable environmental value ANL, which is one of several individual internal environmental values ​​ANw that exceeds the environmental tolerance range, based on the target value information JPP acquired in step S103, the allowable value information JLL acquired in step S107, and the internal environment information JN acquired in step S109 (S113).

[0122] In this embodiment, if an individual internal environmental value ANw is identified as an unacceptable environmental value ANL, that individual internal environmental value ANw is also identified as a modifiable environmental value ANS, which is a physical quantity that should be modified by the environmental adjustment device E to approach the individual target value APw.

[0123] As illustrated in Figure 11, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 identifies an out-of-standard environmental value ANR, which is one of several individual internal environmental values ​​ANw that exceeds the environmental standard range, based on the target value information JPP acquired in step S103, the standard value information JRR acquired in step S107, and the internal environmental information JN acquired in step S109 (S115).

[0124] In this embodiment, if an individual internal environmental value ANw is identified as an out-of-reference environmental value ANR, that individual internal environmental value ANw is also identified as a target environmental value ANS, which is a physical quantity that should be modified by the environmental adjustment device E to approach the individual target value APw.

[0125] As illustrated in Figure 12, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 generates environmental adjustment device information JY based on the internal environmental information JN acquired in step S109 and the external environmental information JG acquired in step S111 (S121).

[0126] Figure 19 shows an example of the data structure of the environmental adjustment device information JY. Here, the environmental adjustment device information JY is information related to the environmental adjustment device EY.

[0127] As illustrated in Figure 19, the environmental adjustment device information JY has multiple records that correspond one-to-one with multiple environmental adjustment devices EY present in the agricultural greenhouse 1. Each record of the environmental adjustment device information JY includes an external device ID, external device name information, operating cost information JYC, and environmental correction capability information JYY.

[0128] The external device ID is information used to identify each environmental control device EY from among all environmental control devices EY present in agricultural greenhouse 1. External device name information refers to information indicating the name of each environmental adjustment device (EY).

[0129] The operating cost information JYC is information that indicates the cost CY incurred when the environmental adjustment device EY is operated. Here, cost CY may be, for example, the amount of electricity consumed per unit time when the environmental adjustment device EY is operated, or the amount of money incurred per unit time when the environmental adjustment device EY is operated.

[0130] In this embodiment, as an example, we assume that the cost CY is a predetermined fixed value. Specifically, in this embodiment, as shown in Figure 19, we assume that the cost CY1 of the window opening device EY1 is "1", the cost CY2 of the ventilation device EY2 is "5", and the cost CY3 of the light-shielding device EY3 is "1".

[0131] The inter-environmental correction capability information JYY is information indicating the ability of the inter-environmental adjustment device EY to correct individual internal environmental values ​​ANw. Specifically, in this embodiment, the inter-environmental correction capability information JYY includes temperature rise capability information JY1, temperature fall capability information JY2, humidity rise capability information JY3, humidity fall capability information JY4, carbon dioxide concentration rise capability information JY5, and illuminance rise capability information JY6.

[0133] In this embodiment, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the window opening device EY1 and the ventilation device EY2 based on the internal temperature AN1 indicated by the internal environment information JN and the external temperature AG1 indicated by the external environment information JG. Specifically, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the internal temperature AN1 from the external temperature AG1 is a positive value, the temperature rise capacity AY1 also becomes a larger positive value as the subtraction value increases. Furthermore, when the subtraction value obtained by subtracting the internal temperature AN1 from the external temperature AG1 is a positive value, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the window opening device EY1 and ventilation device EY2 such that the temperature rise capacity AY1 corresponding to the ventilation device EY2 is a larger positive value than the temperature rise capacity AY1 corresponding to the window opening device EY1. Furthermore, when the subtraction value obtained by subtracting the internal temperature AN1 from the external temperature AG1 is a negative value, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the window opening device EY1 and ventilation device EY2 such that the temperature rise capacity AY1 also becomes a smaller negative value as the subtraction value decreases (that is, the absolute value of the temperature rise capacity AY1 becomes larger as the absolute value of the subtraction value increases).

[0134] Furthermore, in this embodiment, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the light shielding device EY3 based on the external illuminance AG4 indicated by the external environmental information JG. Specifically, the device determination unit 63 sets the temperature rise capacity AY1 corresponding to the light shielding device EY3 such that the temperature rise capacity AY1 becomes a small negative value as the external illuminance AG4 increases.

[0135] Temperature reduction capability information JY2 refers to information indicating the temperature reduction capability AY2, which is the ability of the environmental adjustment device EY to reduce the internal temperature AN1.

[0136] In this embodiment, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the window opening device EY1 and the ventilation device EY2 based on the internal temperature AN1 indicated by the internal environment information JN and the external temperature AG1 indicated by the external environment information JG. Specifically, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the external temperature AG1 from the internal temperature AN1 is a positive value, the temperature reduction capacity AY2 becomes a larger positive value as the subtraction value increases. Also, when the subtraction value obtained by subtracting the external temperature AG1 from the internal temperature AN1 is a positive value, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the window opening device EY1 and ventilation device EY2 such that the temperature reduction capacity AY2 corresponding to the ventilation device EY2 is a larger positive value than the temperature reduction capacity AY2 corresponding to the window opening device EY1.

[0137] Furthermore, in this embodiment, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the light shielding device EY3 based on the external illuminance AG4 indicated by the external environmental information JG. Specifically, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the light shielding device EY3 such that the temperature reduction capacity AY2 becomes a large positive value as the external illuminance AG4 increases.

[0138] In other words, in this embodiment, as an example, we assume that the temperature reduction capacity AY2 is the value obtained by multiplying the temperature increase capacity AY1 by "-1".

[0139] Humidity increase capacity information JY3 refers to information indicating the humidity increase capacity AY3, which is the ability of the environmental adjustment device EY to increase the internal humidity AN2.

Furthermore, the device determination unit 63 sets the temperature reduction capacity AY2 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the internal humidity AN2 from the external humidity AG2 is a negative value, the humidity increase capacity AY3 also becomes a smaller negative value as the subtraction value decreases.

[0141] Humidity reduction capability information JY4 refers to information indicating the humidity reduction capability AY4, which is the ability of the environmental adjustment device EY to reduce the internal humidity AN2.

[0142] In this embodiment, the device determination unit 63 sets the humidity reduction capacity AY4 corresponding to the window opening device EY1 and the ventilation device EY2 based on the internal humidity AN2 indicated by the internal environment information JN and the external humidity AG2 indicated by the external environment information JG. Specifically, the device determination unit 63 sets the humidity reduction capacity AY4 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the external humidity AG2 from the internal humidity AN2 is a positive value, the humidity reduction capacity AY4 also becomes a larger positive value as the subtraction value increases. Furthermore, the device determination unit 63 sets the humidity reduction capacity AY4 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the external humidity AG2 from the internal humidity AN2 is a positive value, the humidity reduction capacity AY4 corresponding to ventilation device EY2 is a larger positive value than the humidity reduction capacity AY4 corresponding to window opening device EY1. Furthermore, when the subtraction value obtained by subtracting the external humidity AG2 from the internal humidity AN2 is a negative value, the device determination unit 63 sets the humidity reduction capacity AY4 corresponding to the window opening device EY1 and ventilation device EY2 such that the humidity reduction capacity AY4 also becomes a smaller negative value as the subtraction value decreases.

[0143] In other words, in this embodiment, as an example, we assume that the humidity reduction capacity AY4 is the value obtained by multiplying the humidity increase capacity AY3 by "-1".

[0144] The carbon dioxide concentration increase capacity information JY5 indicates the carbon dioxide concentration increase capacity AY5, which is the ability of the environmental adjustment device EY to increase the internal carbon dioxide concentration AN3.

[0145] In this embodiment, the device determination unit 63 sets the carbon dioxide concentration increase capacity AY5 corresponding to the window opening device EY1 and the ventilation device EY2 based on the internal carbon dioxide concentration AN3 indicated by the internal environmental information JN and the external carbon dioxide concentration AG3 indicated by the external environmental information JG. Specifically, the device determination unit 63 sets the carbon dioxide concentration increase capacity AY5 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the internal carbon dioxide concentration AN3 from the external carbon dioxide concentration AG3 is a positive value, the carbon dioxide concentration increase capacity AY5 also becomes a larger positive value as the subtraction value increases. Furthermore, the device determination unit 63 sets the carbon dioxide concentration increase capacity AY5 corresponding to the window opening device EY1 and ventilation device EY2 such that, when the subtraction value obtained by subtracting the internal carbon dioxide concentration AN3 from the external carbon dioxide concentration AG3 is a positive value, the carbon dioxide concentration increase capacity AY5 corresponding to ventilation device EY2 becomes a larger positive value than the carbon dioxide concentration increase capacity AY5 corresponding to window opening device EY1. Furthermore, when the subtraction value obtained by subtracting the internal carbon dioxide concentration AN3 from the external carbon dioxide concentration AG3 is a negative value, the device determination unit 63 sets the carbon dioxide concentration increase capacity AY5 corresponding to the window opening device EY1 and ventilation device EY2 such that the carbon dioxide concentration increase capacity AY5 also becomes a smaller negative value as the subtraction value decreases.

[0146] Illuminance increase capability information JY6 refers to information indicating the illuminance increase capability AY6, which is the ability of the environmental adjustment device EY to increase the internal illuminance AN4.

[0147] In this embodiment, the device determination unit 63 sets the illuminance increase capacity AY6 corresponding to the light shielding device EY3 based on the external illuminance AG4 indicated by the external environment information JG. Specifically, the device determination unit 63 sets the illuminance increase capacity AY6 corresponding to the light-shielding device EY3 such that the illuminance increase capacity AY6 becomes a small negative value as the external illuminance AG4 increases.

In other words, the physical quantity correction capability information JZz is information that indicates the physical quantity correction capability AZz.

[0153] As illustrated in Figure 12, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 generates a plurality of device candidate information JK[1] to JK[K] based on the internal environment adjustment device information JX acquired in step S105, the inter-environment adjustment device information JY generated in step S121, the unacceptable environmental value ANL identified in step S113, and the non-standard environmental value ANR identified in step S114 (S123).

[0154] Figures 20 to 23 are diagrams showing examples of the data structure of the candidate device information JK[k]. Here, the candidate device information JK[k] is information about candidate environmental control devices E that should be operated for plant cultivation in the agricultural greenhouse 1.

[0155] In this embodiment, the device determination unit 63 creates K (two or more) candidate combinations of environmental control devices E that should be operated for plant cultivation in the agricultural greenhouse 1 in step S123. Hereinafter, the candidate combination of environmental control devices E indicated by the device candidate information JK[k] may be referred to as the "k-th combination candidate".

[0156] In this embodiment, Figures 20 to 23 show four device candidate information JK[1] to JK[4] based on inter-environment adjustment device information JY generated using internal environment information JN and external environment information JG acquired in the same unit period (hereinafter, the unit period related to Figures 20 to 23 will be referred to as the "first unit period"). Of these, Figure 20 is an example of device candidate information JK[1] relating to the "first combination candidate", Figure 21 is an example of device candidate information JK[2] relating to the "second combination candidate", Figure 22 is an example of device candidate information JK[3] relating to the "third combination candidate", and Figure 23 is an example of device candidate information JK[4] relating to the "fourth combination candidate".

[0157] Here, the unit period may be a period having a duration for which the change in the individual external environmental value AGw related to the external environment is expected to be below a predetermined range, or a period having a duration for which the change in the individual internal environmental value ANw related to the internal environment is expected to be below a predetermined range, or a period having a duration for which the change in the individual external environmental value AGw related to the external environment is below a predetermined range and the change in the individual internal environmental value ANw related to the internal environment is expected to be below a predetermined range. Furthermore, the unit period may be a period having a duration set by the user of the terminal device 9, or a period having a duration predetermined according to the cultivation mode. Furthermore, if the unit period is determined according to the cultivation mode, the unit period in the quality-priority mode may be set shorter than the unit period in the balance mode, and the unit period in the balance mode may be set shorter than the unit period in the cost-priority mode.

[0158] As illustrated in Figures 20 to 23, the candidate device information JK[k] has multiple records that correspond one-to-one with multiple environmental control devices E present in the agricultural greenhouse 1. Each record of the candidate device information JK[k] includes a device ID, device name information, operational status information JKT[k], operational cost information JKC, and environmental modification capability information JKK[k].

[0159] The device ID is information used to identify each environmental control device E from among all environmental control devices E present in the agricultural greenhouse 1, and is a general term for both internal device IDs and external device IDs. Device name information refers to information indicating the name of environmental control device E, and is a general term encompassing both internal device name information and external device name information.

[0160] The operational status information JKT[k] indicates whether or not the environmental control device E will be operated in the k-th combination candidate. In this embodiment, as an example, if the operational status information JKT[k] shows "1", it means that the environmental control device E will be operated in the k-th combination candidate, and if the operational status information JKT[k] shows "0", it means that the environmental control device E will not be operated in the k-th combination candidate.

[0161] Operating cost information JKC is information that indicates the cost CK related to the operation of environmental control device E, which arises depending on the operating status of environmental control device E in the k-th combination candidate. Here, cost CK may be, for example, the amount of electricity consumed per unit time when environmental control device E is operated, or the amount of money incurred per unit time when environmental control device E is operated. In other words, operating cost information JKC is a collective term for operating cost information JXC and operating cost information JYC.

[0162] In the following, the cost CK corresponding to the environmental control device E in the k-th combination candidate may be referred to as "cost CK[k][E]". In this embodiment, the device determination unit 63 sets cost CK[k][E] to "0" if, in the k-th combination candidate, the environmental control device E is not operating and the operating status information JKT[k] corresponding to the environmental control device E indicates "0". Furthermore, if, in the k-th combination candidate, the environmental control device E is operating and the operating status information JKT[k] corresponding to the environmental control device E indicates "1", the device determination unit 63 sets cost CK[k][E] to a value equal to cost CX or cost CY corresponding to the environmental control device E.

[0163] The environmental modification capability information JKK[k] is information that includes some or all of the following: temperature rise capability information JK1[k] corresponding to temperature rise capability information JZ1, temperature decrease capability information JK2[k] corresponding to temperature decrease capability information JZ2, humidity rise capability information JK3[k] corresponding to humidity rise capability information JZ3, humidity decrease capability information JK4[k] corresponding to humidity decrease capability information JZ4, carbon dioxide concentration increase capability information JK5[k] corresponding to carbon dioxide concentration increase capability information JZ5, and illuminance increase capability information JK6[k] corresponding to illuminance increase capability information JZ6.

[0164] Specifically, when the device determination unit 63 determines that the temperature rise capability AZ1 is identified as the specific physical quantity correction capability AZS, it includes the temperature rise capability information JK1[k] corresponding to the temperature rise capability information JZ1 indicating the temperature rise capability AZ1 in the environmental correction capability information JKK[k]. Here, the specific physical quantity correction capability AZS is the physical quantity correction capability AZz that brings the individual internal environmental value ANw, which has been identified as the environmental value to be corrected ANS, closer to the individual target value APw. Note that the temperature rise capability AK1[k] indicated by the temperature rise capability information JK1[k] corresponds to the temperature rise capability AZ1 indicated by the temperature rise capability information JZ1.

[0165] In the following, among the specific physical quantity correction capabilities AZS, the physical quantity correction capability AZz that brings the individual internal environmental value ANw, which has been identified as an unacceptable environmental value ANL, closer to the individual target value APw, may be referred to as the "unacceptable physical quantity correction capability AZL". Furthermore, in the following, among the specific physical quantity correction capabilities AZS, the physical quantity correction capability AZz that brings the individual internal environmental value ANw, which has been identified as an out-of-standard environmental value ANR, closer to the individual target value APw, may be referred to as "out-of-standard physical quantity correction capability AZR".

[0166] Furthermore, when the device determination unit 63 identifies the temperature reduction capability AZ2 as the specific physical quantity correction capability AZS, it includes the temperature reduction capability information JK2[k] corresponding to the temperature reduction capability information JZ2 indicating the temperature reduction capability AZ2 in the environmental correction capability information JKK[k]. Note that the temperature reduction capability AK2[k] indicated by the temperature reduction capability information JK2[k] corresponds to the temperature reduction capability AZ2 indicated by the temperature reduction capability information JZ2.

[0167] Furthermore, when the humidity increase capability AZ3 is identified as the specific physical quantity correction capability AZS, the device determination unit 63 includes humidity increase capability information JK3[k], which corresponds to the humidity increase capability information JZ3 indicating the humidity increase capability AZ3, in the environmental correction capability information JKK[k]. Note that the humidity increase capability AK3[k] indicated by the humidity increase capability information JK3[k] corresponds to the humidity increase capability AZ3 indicated by the humidity increase capability information JZ3.

[0168] Furthermore, when the humidity reduction capability AZ4 is identified as the specific physical quantity correction capability AZS, the device determination unit 63 includes humidity reduction capability information JK4[k], which corresponds to the humidity reduction capability information JZ4 indicating the humidity reduction capability AZ4, in the environmental correction capability information JKK[k]. Note that the humidity reduction capability AK4[k] indicated by the humidity reduction capability information JK4[k] corresponds to the humidity reduction capability AZ4 indicated by the humidity reduction capability information JZ4.

[0169] Furthermore, when the carbon dioxide concentration increase capability AZ5 is identified as the specific physical quantity correction capability AZS, the device determination unit 63 includes carbon dioxide concentration increase capability information JK5[k], which corresponds to the carbon dioxide concentration increase capability information JZ5 indicating the carbon dioxide concentration increase capability AZ5, in the environmental correction capability information JKK[k]. Note that the carbon dioxide concentration increase capability AK5[k] indicated by the carbon dioxide concentration increase capability information JK5[k] corresponds to the carbon dioxide concentration increase capability AZ5 indicated by the carbon dioxide concentration increase capability information JZ5.

[0170] Furthermore, when the illuminance increase capability AZ6 is identified as the specific physical quantity correction capability AZS, the device determination unit 63 includes illuminance increase capability information JK6[k], which corresponds to the illuminance increase capability information JZ6 indicating the illuminance increase capability AZ6, in the environmental correction capability information JKK[k]. Note that the illuminance increase capability AK6[k] indicated by the illuminance increase capability information JK6[k] corresponds to the illuminance increase capability AZ6 indicated by the illuminance increase capability information JZ6.

[0171] In the following, temperature rise capability information JK1[k], temperature fall capability information JK2[k], humidity rise capability information JK3[k], humidity fall capability information JK4[k], carbon dioxide concentration rise capability information JK5[k], and illuminance rise capability information JK6[k] may be collectively referred to as "specific physical quantity correction capability information JKf[k]". Also, in the following, temperature rise capability AK1[k], temperature fall capability AK2[k], humidity rise capability AK3[k], humidity fall capability AK4[k], carbon dioxide concentration rise capability AK5[k], and illuminance rise capability AK6[k] may be collectively referred to as "specific physical quantity correction capability AKf[k]". In other words, specific physical quantity correction capability information JKf[k] is information that indicates specific physical quantity correction capability AKf[k]. Also, in the following, specific physical quantity correction capability AKf[k] corresponding to environmental control device E may be referred to as "specific physical quantity correction capability AKf[k][E]".

[0172] Thus, when the device determination unit 63 determines that the physical quantity correction capability AZz indicated by the physical quantity correction capability information JZz is identified as the specific physical quantity correction capability AZS, it includes the specific physical quantity correction capability information JKf[k] corresponding to the physical quantity correction capability information JZz in the environmental correction capability information JKK[k].

[0173] In this embodiment, if the device determination unit 63 determines that the environmental adjustment device E is not operating in the k-th combination candidate and the operating status information JKT[k] corresponding to the environmental adjustment device E indicates "0", it sets the specific physical quantity correction capability AKf[k][E] to "0". Furthermore, in the k-th combination candidate, if the environmental adjustment device E is operational and the operational status information JKT[k] corresponding to the environmental adjustment device E indicates "1", and the specific physical quantity correction capability information JKf[k] is included in the environmental correction capability information JKK[k], the device determination unit 63 sets the specific physical quantity correction capability AKf[k][E] to a value equal to the physical quantity correction capability AZz.

[0174] In the examples shown in Figures 20 to 23, it is assumed that the internal temperature AN1 is lower than the target temperature AP1, and the difference between the target temperature AP1 and the internal temperature AN1 is greater than the temperature tolerance value AL1. For this reason, in the examples shown in Figures 20 to 23, the device determination unit 63 includes the temperature rise capability information JK1[k] in the environmental correction capability information JKK[k].

[0175] Furthermore, in the examples shown in Figures 20 to 23, we assume a case where the internal humidity AN2 is lower than the target humidity AP2, and the difference between the target humidity AP2 and the internal humidity AN2 is greater than the humidity tolerance value AL2. For this reason, in the examples shown in Figures 20 to 23, the device determination unit 63 includes humidity increase capability information JK3[k] in the environmental correction capability information JKK[k].

[0176] Furthermore, in the examples shown in Figures 20 to 23, we assume a case where the internal carbon dioxide concentration AN3 is lower than the target carbon dioxide concentration AP3, and the difference between the target carbon dioxide concentration AP3 and the internal carbon dioxide concentration AN3 is greater than the allowable carbon dioxide concentration AL3. For this reason, in the examples shown in Figures 20 to 23, the device determination unit 63 includes carbon dioxide concentration increase capacity information JK5[k] in the environmental correction capacity information JKK[k].

[0177] Furthermore, in the examples shown in Figures 20 to 23, it is assumed that the difference between the target illuminance AP4 and the internal illuminance AN4 is less than or equal to the illuminance standard value AR4. In other words, in the examples shown in Figures 20 to 23, it is assumed that the internal illuminance AN4 falls within the environmental standard range. For this reason, in the examples shown in Figures 20 to 23, the device determination unit 63 sets the environmental correction capability information JKK[k] so that the illuminance increase capability information JK6[k] is not included in the environmental correction capability information JKK[k]. In the examples shown in Figures 20 to 23, the device determination unit 63 sets the environmental correction capability information JKK[k] so that the temperature reduction capability information JK2[k] and the humidity reduction capability information JK4[k] are not included in the environmental correction capability information JKK[k].

[0178] Furthermore, in the following, the sum of the specific physical quantity correction capacities AKf[k][E] for all environmental control devices E installed in the agricultural greenhouse 1 will be referred to as the total correction capacity value ASf[k]. Specifically, in this embodiment, the total correction capacity value ASf[k] is defined as "ASf[k] = AKf[k][EX1] + AKf[k][EX2] + AKf[k][EX3] + AKf[k][EX4] + AKf[k][EX5] + AKf[k][EX6] + AKf[k][EY1] + AKf[k][EY2] + AKf[k][EY3]".

[0179] In this embodiment, the device determination unit 63 selects an environmental adjustment device E related to the k-th combination candidate if the specific physical quantity correction capacity AKf[k] indicated by the specific physical quantity correction capacity information JKf[k] included in the environmental correction capacity information JKK[k] corresponds to the unacceptable physical quantity correction capacity AZL, so that the total correction capacity ASf[k] satisfies "ASf[k]≧αL". Here, the threshold αL is a real number that satisfies "0<αL". In this embodiment, as an example, we assume that the threshold αL is "3".

[0180] Furthermore, in this embodiment, if the specific physical quantity correction capacity AKf[k] indicated by the specific physical quantity correction capacity information JKf[k] included in the environmental correction capacity information JKK[k] corresponds to the non-standard physical quantity correction capacity AZR but does not correspond to the non-permissible physical quantity correction capacity AZL, the device determination unit 63 selects the environmental adjustment device E related to the k-th combination candidate such that the total correction capacity value ASf[k] satisfies "ASf[k≧αR]". The threshold αR is a real number that satisfies "0≦αR<αL". In this embodiment, as an example, we assume that the threshold αR is "0".

[0181] In the examples shown in Figures 20 to 23, as described above, it is assumed that the internal temperature AN1 is lower than the target temperature AP1 and the internal temperature AN1 is identified as an unacceptable environmental value ANL, the internal humidity AN2 is lower than the target humidity AP2 and the internal humidity AN2 is identified as an unacceptable environmental value ANL, and the internal carbon dioxide concentration AN3 is lower than the target carbon dioxide concentration AP3 and the internal carbon dioxide concentration AN3 is identified as an unacceptable environmental value ANL. In other words, in the examples shown in Figures 20 to 23, it is assumed that the temperature rise capacity AK1[k] corresponds to the unacceptable physical quantity correction capacity AZL, the humidity rise capacity AK3[k] corresponds to the unacceptable physical quantity correction capacity AZL, and the carbon dioxide concentration rise capacity AK5[k] also corresponds to the unacceptable physical quantity correction capacity AZL. Therefore, in the examples shown in Figures 20 to 23, the device determination unit 63 selects an environmental control device E to be operated in the k-th combination candidate such that the total corrected capacity value AS1[k], which is the sum of the temperature rise capacities AK1[k] indicated by the temperature rise capacity information JK1[k], satisfies "AS1[k]≧αL(=3)", the total corrected capacity value AS3[k], which is the sum of the humidity rise capacities AK3[k] indicated by the humidity rise capacity information JK3[k], satisfies "AS3[k]≧αL(=3)", and the total corrected capacity value AS5[k], which is the sum of the carbon dioxide concentration rise capacities AK5[k] indicated by the carbon dioxide concentration rise capacity information JK5[k], satisfies "AS5[k]≧αL(=3)".

[0182] Specifically, as illustrated in Figure 20, the device determination unit 63 selects the following environmental control devices E to be operated in the "first combination candidate": heating device EX1, humidifier EX3, carbon dioxide supply device EX5, window opening device EY1, and ventilation device EY2. In this case, the total corrected capacity value AS1[1] becomes "12", the total corrected capacity value AS3[1] becomes "8", and the total corrected capacity value AS5[1] becomes "3".

[0183] Furthermore, as illustrated in Figure 21, the device determination unit 63 selects the humidifier EX3, carbon dioxide supply unit EX5, window opening unit EY1, and ventilation unit EY2 as the environmental control devices E to be operated in the "second combination candidate". In this case, the total corrected capacity value AS1[2] becomes "7", the total corrected capacity value AS3[2] becomes "10", and the total corrected capacity value AS5[2] becomes "3".

[0184] Furthermore, as illustrated in Figure 22, the device determination unit 63 selects the carbon dioxide supply unit EX5 and the ventilation unit EY2 as the environmental control devices E to be operated in the "third combination candidate". In this case, the total corrected capacity value AS1[3] becomes "4", the total corrected capacity value AS3[3] becomes "3", and the total corrected capacity value AS5[3] becomes "3".

[0185] Furthermore, as illustrated in Figure 23, the device determination unit 63 selects the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2 as the environmental control devices E to be operated in the "fourth combination candidate". In this case, the total corrected capacity value AS1[4] becomes "7", the total corrected capacity value AS3[4] becomes "5", and the total corrected capacity value AS5[4] becomes "3".

[0186] In the examples shown in Figures 20 to 24, the device determination unit 63 operates the ventilation device EY2 (an example of a "first environmental control device") in order to obtain a temperature rise capacity AK1[k] related to the internal temperature AN1 (an example of a "first physical quantity"). In the examples shown in Figures 20 to 24, the carbon dioxide concentration rise capacity AK5[k][EY2] resulting from the operation of the ventilation device EY2 is "-2". Therefore, in the examples shown in Figures 20 to 24, if the device determination unit 63 were to not operate the carbon dioxide supply device EX5 (an example of a "second environmental control device") in order to obtain a carbon dioxide concentration rise capacity AK5[k] related to the internal carbon dioxide concentration AN3 (an example of a "second physical quantity"), the corrected total capacity value AS5[k] would be "-2", and the corrected total capacity value AS5[k] would fall below the threshold αL (an example of "exceeding a specific standard"). Therefore, in the examples shown in Figures 20 to 24, the device determination unit 63 operates the carbon dioxide supply device EX5 together with the ventilation device EY2, thereby enabling both the total corrected capacity AS1[k] related to the temperature rise capacity AK1[k] to be equal to or greater than the threshold αL, and the total corrected capacity AS5[k] related to the carbon dioxide concentration rise capacity AK5[k] to be equal to or greater than the threshold αL.

[0187] As illustrated in Figure 12, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 generates a plurality of evaluation value information JH[1] to JH[K] based on the plurality of device candidate information JK[1] to JK[K] generated in step S123 (S125).

[0188] Figure 24 shows an example of the data structure of the evaluation value information JH[k].

[0189] As illustrated in Figure 24, the evaluation value information JH[k] includes quality evaluation value information JVH[k], cost evaluation value information JVC[k], balance evaluation value information JVB[k], quality-focused combination evaluation value information JVBH[k], and cost-focused combination evaluation value information JVBC[k] which indicates the cost-focused combination evaluation value VBC[k].

[0190] The quality evaluation value information JVH[k] is information that indicates the quality evaluation value VH[k]. The quality evaluation value VH[k] is the sum of all correction capability sum values ​​ASf[k] in the k-th combination candidate. In the examples shown in Figures 20 to 23, the quality evaluation value VH[k] is defined as "VH[k] = AS1[k] + AS3[k] + AS5[k]".

[0191] Specifically, in the "first combination candidate" illustrated in Figure 20, the quality evaluation value VH[1] is "23". Also, in the "second combination candidate" illustrated in Figure 21, the quality evaluation value VH[2] is "20". Also, in the "third combination candidate" illustrated in Figure 22, the quality evaluation value VH[3] is "10". Also, in the "fourth combination candidate" illustrated in Figure 23, the quality evaluation value VH[4] is "15".

[0192] The cost evaluation value information JVC[k] is information that indicates the cost evaluation value VC[k]. The cost evaluation value VC[k] is the sum of all costs CK[k][E] in the k-th combination candidate. In other words, the cost evaluation value VC[k] is defined as "VC[k] = CK[k][EX1] + CK[k][EX2] + CK[k][EX3] + CK[k][EX4] + CK[k][EX5] + CK[k][EX6] + CK[k][EY1] + CK[k][EY2] + CK[k][EY3]", as illustrated in Figures 20 to 23.

[0193] Specifically, in the "first combination candidate" illustrated in Figure 20, the cost evaluation value VC[1] is "30". Also, in the "second combination candidate" illustrated in Figure 21, the cost evaluation value VC[2] is "20". Also, in the "third combination candidate" illustrated in Figure 22, the cost evaluation value VC[3] is "11". Also, in the "fourth combination candidate" illustrated in Figure 23, the cost evaluation value VC[4] is "12".

[0194] The balance evaluation value information JVB[k] is information that indicates the balance evaluation value VB[k]. The balance evaluation value VB[k] is a value determined based on the quality evaluation value VH[k] and the cost evaluation value VC[k]. Specifically, the balance evaluation value VB[k] is determined such that it increases when the quality evaluation value VH[k] increases, and decreases when the cost evaluation value VC[k] increases. In this embodiment, as an example, we assume that the balance evaluation value VB[k] is determined as "VB[k] = VH[k] - VC[k]".

[0195] Specifically, in the "first combination candidate" illustrated in Figure 20, the balance evaluation value VB[1] is "-7". Also, in the "second combination candidate" illustrated in Figure 21, the balance evaluation value VB[2] is "0". Also, in the "third combination candidate" illustrated in Figure 22, the balance evaluation value VB[3] is "-1". Also, in the "fourth combination candidate" illustrated in Figure 23, the balance evaluation value VB[4] is "3". The ratio of the quality evaluation value VH[k] to the balance evaluation value VB[k] is an example of "the degree to which high plant quality is prioritized in balance mode."

[0196] The quality-focused combination evaluation value information JVBH[k] is information that indicates the quality-focused combination evaluation value VBH[k]. The quality-focused combination evaluation value VBH[k] is a value determined based on the quality evaluation value VH[k], the cost evaluation value VC[k], and the main cultivation mode priority ACY. Specifically, the quality-focused combination evaluation value VBH[k] is determined to increase when the quality evaluation value VH[k] increases, decrease when the cost evaluation value VC[k] increases, and take precedence over the cost evaluation value VC[k] according to the main cultivation mode priority ACY. In this embodiment, as an example, we assume that the quality-focused combination evaluation value VBH[k] is determined as "VBH[k] = ACY*VH[k] - VC[k]".

[0197] Specifically, in this embodiment, we assume that the primary cultivation mode priority ACY is "1.4". Therefore, in the "first combination candidate" illustrated in Figure 20, the quality-focused combination evaluation value VBH[1] is "2.2". Also, in the "second combination candidate" illustrated in Figure 21, the quality-focused combination evaluation value VBH[2] is "8". Also, in the "third combination candidate" illustrated in Figure 22, the quality-focused combination evaluation value VBH[3] is "3". Also, in the "fourth combination candidate" illustrated in Figure 23, the quality-focused combination evaluation value VBH[4] is "9". The ratio of the quality evaluation value VH[k] to the quality-focused combination evaluation value VBH[k] is an example of "the degree of priority given to high plant quality in the quality-focused combination cultivation mode." In this embodiment, the ratio of the quality evaluation value VH[k] to the balance evaluation value VB[k] and the ratio of the quality evaluation value VH[k] to the quality-focused combination evaluation value VBH[k] are different.

[0198] The cost-focused combination evaluation value information JVBC[k] is information that indicates the cost-focused combination evaluation value VBC[k]. The cost-focused combination evaluation value VBC[k] is a value determined based on the quality evaluation value VH[k], the cost evaluation value VC[k], and the main cultivation mode priority ACY. Specifically, the cost-focused combination evaluation value VBC[k] is determined such that when the quality evaluation value VH[k] is large, the quality-focused combination evaluation value VBH[k] is large, and when the cost evaluation value VC[k] is large, the quality-focused combination evaluation value VBH[k] is small, and the cost evaluation value VC[k] is prioritized over the quality evaluation value VH[k] according to the main cultivation mode priority ACY. In this embodiment, as an example, we assume that the cost-focused combination evaluation value VBC[k] is determined as "VBC[k] = VH[k] - ACY*VC[k]".

[0199] Specifically, in the "first combination candidate" illustrated in Figure 20, the cost-focused combination evaluation value VBC[1] is "-19". Also, in the "second combination candidate" illustrated in Figure 21, the cost-focused combination evaluation value VBC[2] is "-8". Furthermore, in the "third combination candidate" illustrated in Figure 22, the cost-focused combination evaluation value VBC[3] is "-5.4". And in the "fourth combination candidate" illustrated in Figure 23, the cost-focused combination evaluation value VBC[4] is "-1.8". The ratio of the quality evaluation value VH[k] to the cost-focused combination evaluation value VBC[k] is an example of "the degree of priority given to high plant quality in the cost-focused combination cultivation mode." In this embodiment, the ratio of the quality evaluation value VH[k] to the balance evaluation value VB[k] and the ratio of the quality evaluation value VH[k] to the cost-focused combination evaluation value VBC[k] are different.

[0200] As illustrated in Figure 12, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 executes the device determination process (S127). Here, the device determination process is the process of determining the environmental adjustment device E that should be operated in the agricultural greenhouse 1 in order to cultivate plants in the agricultural greenhouse 1 based on a cultivation policy according to the cultivation mode.

[0201] Figure 25 is a flowchart showing an example of the operation of server device 5 when it performs device determination processing.

[0202] As illustrated in Figure 25, when the device determination process is started, the device determination unit 63 provided in the server device 5 determines whether the cultivation mode in the agricultural greenhouse 1 is the quality priority mode based on the selection mode information JC included in the cultivation target information JT (S201).

[0203] Specifically, in step S201, the device determination unit 63 determines whether the conditions are met, namely that the main cultivation mode information JC1 among the selected mode information JC indicates a cultivation mode ID corresponding to the quality priority mode, and that a Null value is set for the secondary cultivation mode information JC2. If these conditions are met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is the quality priority mode. If these conditions are not met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is not the quality priority mode.

[0204] If the result of the determination in step S201 is negative, the device determination unit 63 proceeds to step S205.

[0205] If the result of the determination in step S201 is positive, the device determination unit 63 determines the environmental control device E that should be operated in the cultivation of plants in the agricultural greenhouse 1 based on the quality evaluation values ​​VH[1] to VH[K] (S203).

[0206] Specifically, in step S203, the device determination unit 63 first identifies the maximum quality evaluation value VH[k] among the quality evaluation values ​​VH[1] to VH[K]. Next, in step S203, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 based on the device candidate information JK[k] corresponding to the maximum quality evaluation value VH[k] among the quality evaluation values ​​VH[1] to VH[K]. More specifically, in step S203, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 if the operational status information JKT[k] included in the device candidate information JK[k] corresponding to the maximum quality evaluation value VH[k] among the quality evaluation values ​​VH[1] to VH[K] is "1".

[0207] In the examples shown in Figures 20 to 23, as described above, the quality evaluation value VH[1] is "23", the quality evaluation value VH[2] is "20", the quality evaluation value VH[3] is "10", and the quality evaluation value VH[4] is "15". In other words, in the examples shown in Figures 20 to 23, the quality evaluation value VH[1] is the largest among the quality evaluation values ​​VH[1] to VH[4]. Therefore, in the first unit period illustrated in Figures 20 to 23, if the quality priority mode is selected, the environmental control devices E whose operational status information JKT[1] included in the device candidate information JK[1] is "1", namely the heating device EX1, the humidifier EX3, the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are determined to be the environmental control devices E that should be operated in the agricultural greenhouse 1.

[0208] As illustrated in Figure 25, the device determination unit 63 determines whether the cultivation mode in the agricultural greenhouse 1 is the cost-priority mode based on the selection mode information JC included in the cultivation target information JT (S205).

[0209] Specifically, in step S205, the device determination unit 63 determines whether the conditions are met, namely that the main cultivation mode information JC1 among the selected mode information JC indicates a cultivation mode ID corresponding to the cost-priority mode, and that the sub-cultivation mode information JC2 is set to a Null value. If these conditions are met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is the cost-priority mode. If these conditions are not met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is not the cost-priority mode.

[0210] If the result of the determination in step S205 is negative, the device determination unit 63 proceeds to step S209.

[0211] If the result of the determination in step S205 is positive, the device determination unit 63 determines the environmental control device E that should be operated in the cultivation of plants in the agricultural greenhouse 1 based on the cost evaluation values ​​VC[1] to VC[K] (S207).

[0212] Specifically, in step S207, the device determination unit 63 first identifies the smallest cost evaluation value VC[k] among the cost evaluation values ​​VC[1] to VC[K]. Next, in step S207, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 based on the device candidate information JK[k] corresponding to the smallest cost evaluation value VC[k] among the cost evaluation values ​​VC[1] to VC[K]. More specifically, in step S207, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 if the operational status information JKT[k] included in the device candidate information JK[k] corresponding to the smallest cost evaluation value VC[k] among the cost evaluation values ​​VC[1] to VC[K] is "1".

[0213] In the examples shown in Figures 20 to 23, as described above, the cost evaluation value VC[1] is "30", the cost evaluation value VC[2] is "20", the cost evaluation value VC[3] is "11", and the cost evaluation value VC[4] is "12". In other words, in the examples shown in Figures 20 to 23, the cost evaluation value VC[3] is the smallest among the cost evaluation values ​​VC[1] to VC[4]. Therefore, in the first unit period illustrated in Figures 20 to 23, if the cost priority mode is selected, the environmental control devices E whose operational status information JKT[3] included in the device candidate information JK[3] is "1", namely the carbon dioxide supply device EX5 and the ventilation device EY2, are determined to be the environmental control devices E to be operated in the agricultural greenhouse 1.

[0214] As illustrated in Figure 25, the device determination unit 63 determines whether the cultivation mode in the agricultural greenhouse 1 is the balance mode based on the selection mode information JC included in the cultivation target information JT (S209).

[0215] Specifically, in step S209, the device determination unit 63 determines whether the conditions are met, namely that the main cultivation mode information JC1 among the selected mode information JC indicates a cultivation mode ID corresponding to the balance mode, and that the sub-cultivation mode information JC2 is set to a Null value. If these conditions are met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is the balance mode. If these conditions are not met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is not the balance mode.

[0216] If the result of the determination in step S209 is negative, the device determination unit 63 proceeds to step S213.

[0217] If the result of the determination in step S209 is positive, the device determination unit 63 determines the environmental control device E that should be operated in the cultivation of plants in the agricultural greenhouse 1 based on the balance evaluation values ​​VB[1] to VB[K] (S211).

[0218] Specifically, in step S211, the device determination unit 63 first identifies the maximum balance evaluation value VB[k] among the balance evaluation values ​​VB[1] to VB[K]. Next, in step S211, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 based on the device candidate information JK[k] corresponding to the maximum balance evaluation value VB[k] among the balance evaluation values ​​VB[1] to VB[K]. More specifically, in step S211, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 if the operational status information JKT[k] included in the device candidate information JK[k] corresponding to the maximum balance evaluation value VB[k] among the balance evaluation values ​​VB[1] to VB[K] is "1".

[0219] In the examples shown in Figures 20 to 23, as described above, the balance evaluation value VB[1] is "-7", the balance evaluation value VB[2] is "0", the balance evaluation value VB[3] is "-1", and the balance evaluation value VB[4] is "3". In other words, in the examples shown in Figures 20 to 23, the balance evaluation value VB[4] is the largest among the balance evaluation values ​​VB[1] to VB[4]. Therefore, in the first unit period illustrated in Figures 20 to 23, if the balance mode is selected, the environmental control devices E whose operational status information JKT[4] included in the device candidate information JK[4] is "1", namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are determined to be the environmental control devices E that should be operated in the agricultural greenhouse 1.

[0220] As illustrated in Figure 25, the device determination unit 63 determines whether the cultivation mode in the agricultural greenhouse 1 is a quality-focused combined cultivation mode based on the selection mode information JC included in the cultivation target information JT (S213).

[0221] Specifically, in step S213, the device determination unit 63 determines whether either of the following two conditions is met: the condition that the main cultivation mode information JC1 in the selected mode information JC indicates a cultivation mode ID corresponding to the quality-priority mode, and the sub-cultivation mode information JC2 indicates a cultivation mode ID corresponding to the cost-priority mode or the balance mode; and the condition that the main cultivation mode information JC1 in the selected mode information JC indicates a cultivation mode ID corresponding to the balance mode, and the sub-cultivation mode information JC2 indicates a cultivation mode ID corresponding to the quality-priority mode. The device determination unit 63 then determines that the cultivation mode in the agricultural greenhouse 1 is a quality-priority combination cultivation mode if either of the two conditions is met. If neither of the two conditions is met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is not a quality-priority combination cultivation mode.

[0222] If the result of the determination in step S213 is negative, the device determination unit 63 proceeds to step S217.

[0223] If the result of the determination in step S213 is positive, the device determination unit 63 determines the environmental control device E that should be operated in the cultivation of plants in the agricultural greenhouse 1 based on the quality-focused combination evaluation values ​​VBH[1] to VBH[K] (S215).

[0224] Specifically, in step S215, the device determination unit 63 first identifies the largest quality-focused combination evaluation value VBH[k] among the quality-focused combination evaluation values ​​VBH[1] to VBH[K]. Next, in step S215, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 based on the device candidate information JK[k] corresponding to the largest quality-focused combination evaluation value VBH[k] among the quality-focused combination evaluation values ​​VBH[1] to VBH[K]. More specifically, in step S215, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 if the operational status information JKT[k] included in the device candidate information JK[k] corresponding to the largest quality-focused combination evaluation value VBH[k] among the quality-focused combination evaluation values ​​VBH[1] to VBH[K] is "1".

[0225] In the examples shown in Figures 20 to 23, as described above, the quality-focused combination evaluation value VBH[1] is "2.2", the quality-focused combination evaluation value VBH[2] is "8", the quality-focused combination evaluation value VBH[3] is "3", and the quality-focused combination evaluation value VBH[4] is "9". In other words, in the examples shown in Figures 20 to 23, the quality-focused combination evaluation value VBH[4] is the largest among the quality-focused combination evaluation values ​​VBH[1] to VBH[4]. Therefore, in the first unit period illustrated in Figures 20 to 23, when the quality-focused combination cultivation mode is selected, the environmental control devices E whose operational status information JKT[4] included in the device candidate information JK[4] is "1", namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are determined to be the environmental control devices E to be operated in the agricultural greenhouse 1.

[0226] As illustrated in Figure 25, the device determination unit 63 determines whether the cultivation mode in the agricultural greenhouse 1 is a cost-conscious combination cultivation mode based on the selection mode information JC included in the cultivation target information JT (S217).

[0227] Specifically, in step S213, the device determination unit 63 determines whether either of the following two conditions is met: the condition that the main cultivation mode information JC1 in the selection mode information JC indicates a cultivation mode ID corresponding to cost priority mode, and the sub-cultivation mode information JC2 indicates a cultivation mode ID corresponding to quality priority mode or balance mode; and the condition that the main cultivation mode information JC1 in the selection mode information JC indicates a cultivation mode ID corresponding to balance mode, and the sub-cultivation mode information JC2 indicates a cultivation mode ID corresponding to cost priority mode. The device determination unit 63 then determines that the cultivation mode in the agricultural greenhouse 1 is a cost-prioritizing combination cultivation mode if either of the two conditions is met. If neither of the two conditions is met, the device determination unit 63 determines that the cultivation mode in the agricultural greenhouse 1 is not a cost-prioritizing combination cultivation mode.

[0228] If the result of the determination in step S217 is negative, the device determination unit 63 terminates the device determination process.

[0229] If the result of the determination in step S217 is positive, the device determination unit 63 determines the environmental control device E that should be operated in the cultivation of plants in the agricultural greenhouse 1 based on the cost-conscious combination evaluation values ​​VBC[1] to VBC[K] (S219).

[0230] Specifically, in step S219, the device determination unit 63 first identifies the largest cost-focused combination evaluation value VBC[k] among the cost-focused combination evaluation values ​​VBC[1] to VBC[K]. Next, in step S219, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 based on the device candidate information JK[k] corresponding to the largest cost-focused combination evaluation value VBC[k] among the cost-focused combination evaluation values ​​VBC[1] to VBC[K]. More specifically, in step S219, the device determination unit 63 determines the environmental control device E that should be operated in the agricultural greenhouse 1 if the operational status information JKT[k] included in the device candidate information JK[k] corresponding to the largest cost-focused combination evaluation value VBC[k] among the cost-focused combination evaluation values ​​VBC[1] to VBC[K] is "1".

[0231] In the examples shown in Figures 20 to 23, as described above, the cost-conscious combination evaluation value VBC[1] is "-19", the cost-conscious combination evaluation value VBC[2] is "-8", the cost-conscious combination evaluation value VBC[3] is "-5.4", and the cost-conscious combination evaluation value VBC[4] is "-1.8". In other words, in the examples shown in Figures 20 to 23, the cost-conscious combination evaluation value VBC[4] is the largest among the cost-conscious combination evaluation values ​​VBC[1] to VBC[4]. Therefore, in the first unit period illustrated in Figures 20 to 23, if the cost-conscious combination cultivation mode is selected, the environmental adjustment devices E whose operational status information JKT[4] included in the device candidate information JK[4] is "1", namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are determined to be the environmental adjustment devices E to be operated in the agricultural greenhouse 1.

[0232] As described above, the device determination unit 63 performs a device determination process in step S127 to determine the environmental control device E that should be operated in the agricultural greenhouse 1 in order to cultivate plants in the agricultural greenhouse 1 based on a cultivation policy according to the cultivation mode.

[0233] As illustrated in Figure 12, in the plant cultivation adjustment process, the device determination unit 63 provided in the server device 5 generates determined device information JDF based on the results of the device determination process (S129). Here, the determined device information JDF is information indicating one or more environmental adjustment devices E operating in the agricultural greenhouse 1.

[0234] As illustrated in Figure 12, in the plant cultivation adjustment process, the device control unit 64 provided in the server device 5 controls a plurality of environmental adjustment devices E provided in the agricultural greenhouse 1 based on the determination device information JDF (S131). Specifically, in step S131, the device control unit 64 operates the environmental adjustment device E indicated by the determination device information JDF, which is determined based on the cultivation mode selected from among the plurality of cultivation modes provided in the agricultural greenhouse 1.

[0235] As illustrated in Figure 12, in the plant cultivation adjustment process, the device control unit 64 provided in the server device 5 determines whether a unit period has elapsed since the time when the internal environmental information JN was acquired in step S109 (S133).

[0236] If the result of the determination in step S133 is positive, the device control unit 64 proceeds to step S109.

[0237] If the result of the determination in step S133 is negative, the device control unit 64 determines whether the termination condition, which is the condition for ending the plant cultivation adjustment process, has been met (S135).

[0238] If the result of the determination in step S135 is negative, the device control unit 64 proceeds to step S131. If the result of the determination in step S135 is positive, the device control unit 64 terminates the plant cultivation adjustment process.

[0239] In this embodiment, we assume that in a unit period different from the first unit period (hereinafter referred to as the "second unit period"), some or all of the multiple individual internal environmental values ​​ANw change to values ​​different from those in the first unit period.

[0240] Specifically, in this embodiment, it is assumed that in the second unit period, the internal humidity AN2 is lower than the target humidity AP2, the difference between the target humidity AP2 and the internal humidity AN2 is greater than the humidity standard value AR2, and is less than or equal to the humidity tolerance value AL2. Furthermore, in this embodiment, it is assumed that in the second unit period, the internal carbon dioxide concentration AN3 is lower than the target carbon dioxide concentration AP3, the difference between the target carbon dioxide concentration AP3 and the internal carbon dioxide concentration AN3 is greater than the carbon dioxide concentration standard value AR3, and is less than or equal to the carbon dioxide concentration tolerance value AL3. In other words, in this embodiment, we assume that in the first unit period, the internal humidity AN2 and internal carbon dioxide concentration AN3 are not within the environmentally acceptable range, while in the second unit period, the internal humidity AN2 and internal carbon dioxide concentration AN3 are within the environmentally acceptable range but not within the environmental standard range.

[0241] In this embodiment, it is assumed that in the second unit period, the internal temperature AN1 is lower than the target temperature AP1, and the difference between the target temperature AP1 and the internal temperature AN1 is greater than the temperature tolerance value AL1. In other words, in this embodiment, it is assumed that the internal temperature AN1 in the second unit period is not within the environmental tolerance range, similar to the internal temperature AN1 in the first unit period. Furthermore, in this embodiment, it is assumed that the internal illuminance AN4 in the second unit period falls within the environmental standard range, similar to the internal illuminance AN4 in the first unit period.

[0242] In other words, in this embodiment, we assume that in the second unit period, the internal temperature AN1 is lower than the target temperature AP1, and the internal temperature AN1 is identified as an unacceptable environmental value ANL; the internal humidity AN2 is lower than the target humidity AP2, and the internal humidity AN2 is identified as an unacceptable environmental value ANR; and the internal carbon dioxide concentration AN3 is lower than the target carbon dioxide concentration AP3, and the internal carbon dioxide concentration AN3 is identified as an unacceptable environmental value ANR. In other words, in this embodiment, we assume that in the second unit period, the temperature rise capacity AK1[k] corresponds to the unacceptable physical quantity correction capacity AZL; the humidity rise capacity AK3[k] corresponds to the unacceptable physical quantity correction capacity AZR; and the carbon dioxide concentration rise capacity AK5[k] also corresponds to the unacceptable physical quantity correction capacity AZR. Therefore, in this embodiment, the device determination unit 63 selects an environmental control device E to be operated in the agricultural greenhouse 1 in the second unit period such that the total corrected capacity value AS1[k], which is the sum of the temperature rise capacity AK1[k] indicated by the temperature rise capacity information JK1[k], satisfies "AS1[k]≧αL", the total corrected capacity value AS3[k], which is the sum of the humidity rise capacity AK3[k] indicated by the humidity rise capacity information JK3[k], satisfies "AS3[k]≧αR", and the total corrected capacity value AS5[k], which is the sum of the carbon dioxide concentration rise capacity AK5[k] indicated by the carbon dioxide concentration rise capacity information JK5[k], satisfies "AS5[k]≧αR". More specifically, in this embodiment, the device determination unit 63 selects, as an example, an environmental control device E to be operated in the agricultural greenhouse 1 such that, in a second unit period, it satisfies "AS1[k]≧3", "AS3[k]≧0", and "AS5[k]≧0".

[0243] In this embodiment, as an example, we assume that in the second unit period, as a process related to step S123, the device determination unit 63 generates four device candidate information JK[1] to JK[4] shown in Figures 20 to 23, in addition to four device candidate information JK[5] to JK[8] shown in Figures 26 to 29, based on the internal environment information JN and external environment information JG acquired by the cultivation-related information acquisition unit 61.

[0244] Specifically, in the second unit period, as shown in the device candidate information JK[5] illustrated in FIG. 26, the device determination unit 63 selects the heating device EX1, the carbon dioxide supply device EX5, and the ventilation device EY2 as the environmental adjustment devices E to operate in the "fifth combination candidate". In this case, the total correction ability value AS1[5] is "9", the total correction ability value AS3[5] is "1", and the total correction ability value AS5[5] is "3".

[0245] Also, in the second unit period, as shown in the device candidate information JK[6] illustrated in FIG. 27, the device determination unit 63 selects the heating device EX1, the carbon dioxide supply device EX5, and the window opening device EY1 as the environmental adjustment devices E to operate in the "sixth combination candidate". In this case, the total correction ability value AS1[6] is "8", the total correction ability value AS3[6] is "0", and the total correction ability value AS5[6] is "5".

[0246] Also, in the second unit period, as shown in the device candidate information JK[7] illustrated in FIG. 28, the device determination unit 63 selects the window opening device EY1 as the environmental adjustment device E to operate in the "seventh combination candidate". In this case, the total correction ability value AS1[7] is "3", the total correction ability value AS3[7] is "2", and the total correction ability value AS5[7] is "0".

[0247] Also, in the second unit period, as shown in the device candidate information JK[8] illustrated in FIG. 29, the device determination unit 63 selects the heating device EX1 and the window opening device EY1 as the environmental adjustment devices E to operate in the "eighth combination candidate". In this case, the total correction ability value AS1[8] is "8", the total correction ability value AS3[8] is "D", and the total correction ability value AS5[8] is "0".

[0248] In the present embodiment, as an example, it is assumed that in the second unit period, as the process according to step S125, the evaluation value information JH[5] to JH[8] is generated based on the device candidate information JK[5] to JK[8] generated by the device determination unit 63.

[0249] Figure 30 is a diagram showing an example of evaluation value information JH[5] to JH[8].

[0250] As illustrated in FIG. 30, the evaluation value information JH[5] to JH[8] includes quality evaluation values VH[5] to VH[8], cost evaluation values VC[5] to VC[8], balance evaluation values VB[5] to VB[8], quality - focused combination evaluation values VBH[5] to VBH[8], and cost - focused combination evaluation values VBC[5] to VBC[8].

[0251] As illustrated in FIG. 30, in the examples shown in FIGS. 26 to 29, the quality evaluation value VH[5] is "13", the quality evaluation value VH[6] is "13", the quality evaluation value VH[7] is "5", and the quality evaluation value VH[8] is "8". That is, in the examples shown in FIGS. 26 to 29, among the quality evaluation values VH[5] to VH[8], the quality evaluation values VH[5] and VH[6] indicating "13" are the maximum. Among the quality evaluation values VH[1] to VH[4], the quality evaluation value VH[1] indicating "23" is the maximum, and among the quality evaluation values VH[1] to VH[8], the quality evaluation value VH[1] indicating "23" is the maximum.

[0252] As described above, when the cultivation mode in the agricultural house 1 is the quality - priority mode, the device determination unit 63 determines, in the device determination process of step S127, the environmental adjustment device E to be operated in the agricultural house 1 based on the quality evaluation values VH[1] to VH[4] in the first unit period and determines the environmental adjustment device E to be operated in the agricultural house 1 based on the quality evaluation values VH[1] to VH[8] in the second unit period. Therefore, when the cultivation mode in the agricultural greenhouse 1 is the quality priority mode, the device determination unit 63 determines, in the first unit period, that the environmental control devices E defined by the device candidate information JK[1] corresponding to the quality evaluation value VH[1], namely the heating device EX1, the humidifier EX3, the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are to be operated in the agricultural greenhouse 1. Similarly, in the second unit period, the device determination unit 63 determines, that the environmental control devices E defined by the device candidate information JK[1] corresponding to the quality evaluation value VH[1], namely the heating device EX1, the humidifier EX3, the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, are to be operated in the agricultural greenhouse 1.

[0253] As illustrated in Figure 30, in the examples shown in Figures 26 to 29, the cost evaluation value VC[5] is "21", the cost evaluation value VC[6] is "17", the cost evaluation value VC[7] is "1", and the cost evaluation value VC[8] is "11". In other words, in the examples shown in Figures 26 to 29, among the cost evaluation values ​​VC[5] to VC[8], the cost evaluation value VC[7], which is "1", is the smallest. Furthermore, among the cost evaluation values ​​VC[1] to VC[4], the quality evaluation value VH[3], which is "11", is the smallest, and among the cost evaluation values ​​VC[1] to VC[8], the quality evaluation value VH[7], which is "1", is the smallest.

[0254] As described above, if the cultivation mode in the agricultural greenhouse 1 is the cost-priority mode, the device determination unit 63, in the device determination process of step S127, determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the cost evaluation values ​​VC[1] to VC[4] in the first unit period, and determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the cost evaluation values ​​VC[1] to VC[8] in the second unit period. Therefore, if the cultivation mode in the agricultural greenhouse 1 is the cost-priority mode, the device determination unit 63 determines, in the first unit period, that the environmental control device E defined by the device candidate information JK[3] corresponding to the cost evaluation value VC[3], namely the carbon dioxide supply device EX5 and the ventilation device EY2, is the environmental control device E to be operated in the agricultural greenhouse 1, and in the second unit period, that the environmental control device E defined by the device candidate information JK[7] corresponding to the cost evaluation value VC[7], namely the window opening device EY1, is the environmental control device E to be operated in the agricultural greenhouse 1.

[0255] As illustrated in Figure 30, in the examples shown in Figures 26 to 29, the balance evaluation value VB[5] is "-8", the balance evaluation value VB[6] is "-4", the balance evaluation value VB[7] is "4", and the balance evaluation value VB[8] is "-3". In other words, in the examples shown in Figures 26 to 29, among the balance evaluation values ​​VB[5] to VB[8], the balance evaluation value VB[7], which is "4", is the largest. Among the balance evaluation values ​​VB[1] to VB[4], the balance evaluation value VB[4], which is "3", is the largest, and among the balance evaluation values ​​VB[1] to VB[8], the balance evaluation value VB[7], which is "4", is the largest.

[0256] As described above, when the cultivation mode in the agricultural greenhouse 1 is the balance mode, the device determination unit 63, in the device determination process of step S127, determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the balance evaluation values ​​VB[1] to VB[4] in the first unit period, and determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the balance evaluation values ​​VB[1] to VB[8] in the second unit period. Therefore, when the cultivation mode in the agricultural greenhouse 1 is the balance mode, the device determination unit 63 determines, in the first unit period, that the environmental control device E defined by the device candidate information JK[4] corresponding to the balance evaluation value VB[4], namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, be the environmental control device E to be operated in the agricultural greenhouse 1, and in the second unit period, that the environmental control device E defined by the device candidate information JK[7] corresponding to the balance evaluation value VB[7], namely the window opening device EY1, be the environmental control device E to be operated in the agricultural greenhouse 1.

[0257] As illustrated in Figure 30, in the examples shown in Figures 26 to 29, the quality-focused combination evaluation value VBH[5] is "-2.8", the quality-focused combination evaluation value VBH[6] is "1.2", the quality-focused combination evaluation value VBH[7] is "6", and the quality-focused combination evaluation value VBH[8] is "0.2". In other words, in the examples shown in Figures 26 to 29, among the quality-focused combination evaluation values ​​VBH[1] to VBH[8], the quality-focused combination evaluation value VBH[7], which shows "6", is the largest. Furthermore, among the quality-focused combination evaluation values ​​VBH[1] to VBH[4], the quality-focused combination evaluation value VBH[4], which shows "9", is the largest, and among the quality-focused combination evaluation values ​​VBH[1] to VBH[8], the quality-focused combination evaluation value VBH[4], which shows "9", is the largest.

[0258] As described above, if the cultivation mode in the agricultural greenhouse 1 is the quality-focused combination cultivation mode, the device determination unit 63, in the device determination process of step S127, determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the quality-focused combination evaluation values ​​VBH[1] to VBH[4] in the first unit period, and determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the quality-focused combination evaluation values ​​VBH[1] to VBH[8] in the second unit period. Therefore, when the cultivation mode in the agricultural greenhouse 1 is the quality-focused combination cultivation mode, the device determination unit 63 determines, in the first unit period, that the environmental control device E defined by the device candidate information JK[4] corresponding to the quality-focused combination evaluation value VBH[4], namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, should be operated in the agricultural greenhouse 1. In the second unit period, the device determination unit 63 determines, that the environmental control device E defined by the device candidate information JK[4] corresponding to the quality-focused combination evaluation value VBH[4], namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, should be operated in the agricultural greenhouse 1.

[0259] As illustrated in Figure 30, in the examples shown in Figures 26 to 29, the cost-focused combination evaluation value VBC[5] is "-16.4", the cost-focused combination evaluation value VBC[6] is "-10.8", the cost-focused combination evaluation value VBC[7] is "3.6", and the cost-focused combination evaluation value VBC[8] is "-7.4". In other words, in the examples shown in Figures 26 to 29, among the cost-focused combination evaluation values ​​VBC[5] to VBC[8], the cost-focused combination evaluation value VBC[7], which shows "3.6", is the largest. Among the cost-focused combination evaluation values ​​VBC[1] to VBC[4], the cost-focused combination evaluation value VBC[4], which shows "-1.8", is the largest, and among the cost-focused combination evaluation values ​​VBC[1] to VBC[8], the cost-focused combination evaluation value VBC[7], which shows "3.6", is the largest.

[0260] As described above, if the cultivation mode in the agricultural greenhouse 1 is a cost-conscious combination cultivation mode, the device determination unit 63, in the device determination process of step S127, determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the cost-conscious combination evaluation values ​​VBC[1] to VBC[4] in the first unit period, and determines the environmental control device E to be operated in the agricultural greenhouse 1 based on the cost-conscious combination evaluation values ​​VBC[1] to VBC[8] in the second unit period. Therefore, if the cultivation mode in the agricultural greenhouse 1 is a cost-conscious combination cultivation mode, the device determination unit 63 determines, in the first unit period, that the environmental control device E defined by the device candidate information JK[4] corresponding to the cost-conscious combination evaluation value VBC[4], namely the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2, be the environmental control device E to be operated in the agricultural greenhouse 1. In the second unit period, the device determination unit 63 determines, in the second unit period, that the environmental control device E defined by the device candidate information JK[7] corresponding to the cost-conscious combination evaluation value VBC[7], namely the window opening device EY1, be the environmental control device E to be operated in the agricultural greenhouse 1.

[0261] As described above, in this embodiment, when the cultivation mode is quality priority mode, the device control unit 64 operates the heating device EX1, humidifier EX3, carbon dioxide supply device EX5, window opening device EY1, and ventilation device EY2 corresponding to the device candidate information JK[1] during the first unit period, and also operates the heating device EX1, humidifier EX3, carbon dioxide supply device EX5, window opening device EY1, and ventilation device EY2 corresponding to the device candidate information JK[1] during the second unit period. Furthermore, if the cultivation mode is a quality-focused combined cultivation mode, the device control unit 64 operates the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2 corresponding to the device candidate information JK[4] during the first unit period, and also operates the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2 corresponding to the device candidate information JK[4] during the second unit period.

[0262] In response to this, the device control unit 64 operates the carbon dioxide supply device EX5 and ventilation device EY2, which correspond to the device candidate information JK[3], during the first unit period, and operates the window opening device EY1, which corresponds to the device candidate information JK[7], during the second unit period. In other words, when the cultivation mode is cost-priority mode, the device control unit 64 changes the environmental control device E that should be operated in the agricultural greenhouse 1 from the carbon dioxide supply device EX5 and ventilation device EY2 to the window opening device EY1 in response to the fluctuations in internal humidity AN2 and internal carbon dioxide concentration AN3 that occur when transitioning from the first unit period to the second unit period.

[0263] Furthermore, when the cultivation mode is in balance mode, the device control unit 64 operates the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2 corresponding to the device candidate information JK[4] during the first unit period, and operates the window opening device EY1 corresponding to the device candidate information JK[7] during the second unit period. In other words, when the cultivation mode is in balance mode, the device control unit 64 stops the carbon dioxide supply device EX5 and the ventilation device EY2 that were operating during the first unit period and switches to operating only the window opening device EY1 in response to the fluctuations in internal humidity AN2 and internal carbon dioxide concentration AN3 that occur when transitioning from the first unit period to the second unit period.

[0264] Furthermore, when the cultivation mode is the cost-conscious combination cultivation mode, the device control unit 64 operates the carbon dioxide supply device EX5, the window opening device EY1, and the ventilation device EY2 corresponding to the device candidate information JK[4] during the first unit period, and operates the window opening device EY1 corresponding to the device candidate information JK[7] during the second unit period. In other words, when the cultivation mode is the cost-conscious combination cultivation mode, the device control unit 64 stops the carbon dioxide supply device EX5 and the ventilation device EY2 that were operating during the first unit period and switches to operating only the window opening device EY1 in response to the fluctuations in internal humidity AN2 and internal carbon dioxide concentration AN3 that occur when transitioning from the first unit period to the second unit period.

[0265] <3. Embodiment Conclusion> As described above, in this embodiment, the device determination unit 63 selects one or more environmental control devices E suitable for the internal environment and external environment in the agricultural house 1 based on the evaluation value information JH[k] determined according to the individual internal environment value ANw indicated by the internal environment information JN and the individual external environment value AGw indicated by the external environment information JG, according to the cultivation mode applied to the cultivation of plants in the agricultural house 1. Then, the device control unit 64 operates the one or more environmental control devices E determined by the device determination unit 63. Therefore, according to this embodiment, in the agricultural house 1, it is possible to easily perform the cultivation of plants based on the cultivation policy indicated by the cultivation mode.

[0266] <B. Variation> Each of the above embodiments can be variously modified. Specific modification modes are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined within a range where they do not conflict with each other. In the variation examples exemplified below, for elements whose actions and functions are equivalent to those of the embodiment, the reference numerals referred to in the above description are reused, and the detailed description of each is appropriately omitted.

[0267] <Variation 1> In the above-described embodiment, an aspect in which the external environment sensor SYw provided in the agricultural house 1 of the plant cultivation system Sys acquires the external environment information JG has been exemplified and described, but the present invention is not limited to such an aspect. The terminal device 9 may acquire, for example, a part or all of a plurality of individual external environment information JGw included in the external environment information JG from a climate server that manages information on the climate of each region via the network NW. Here, the information that the terminal device 9 acquires from the climate server as the external environment information JG may be, for example, information on the climate of the region where the agricultural house 1 is located.

[0268] <Variation 2> In the above-described embodiment and modified example 1, the device determination unit 63 selects a device candidate information JK[k] corresponding to the cultivation mode from among a plurality of device candidate information JK[1] to JK[K] based on the evaluation value information JH[1] to JH[K], thereby selecting the environmental adjustment device E corresponding to the device candidate information JK[k] as the environmental adjustment device E to be operated in the agricultural greenhouse 1. However, the present invention is not limited to this embodiment. For example, the device determination unit 63 may select the environmental adjustment device E based on the physical quantity correction capability AZz indicated by the physical quantity correction capability information JZz.

[0269] Specifically, in this modified example, the device determination unit 63 selects an environmental control device E (an example of a "first environmental control device") whose physical quantity correction capacity AZz is less than or equal to the reference value AZ0 as the environmental control device E to operate in the agricultural greenhouse 1, when the difference between the individual internal environmental value ANw indicated by the individual internal environmental information JNw and the individual target value APw indicated by the individual target value information JPw is greater than the individual reference value ARw (an example of a "first threshold"), and the difference is less than or equal to the individual tolerance value ALw, that is, when the individual internal environmental value ANw is within the environmental tolerance range. Furthermore, in this modified example, the device determination unit 63 selects an environmental control device E (an example of a "second environmental control device") with a physical quantity correction capacity AZz greater than the reference value AZ0 as the environmental control device E to operate in the agricultural greenhouse 1, when the difference between the individual internal environmental value ANw and the individual target value APw is greater than the individual tolerance value ALw (an example of a "second threshold") and the individual internal environmental value ANw is not included in the environmental tolerance range.

[0270] For example, the following assumes that the internal environment adjustment device information JX represents the physical quantity correction capacity AXz illustrated in Figure 15, and the inter-environment adjustment device information JY represents the physical quantity correction capacity AYz illustrated in Figure 19. In other words, the following assumes that the temperature rise capacity AX1 of the heating device EX1 is "5", and the temperature rise capacity AX1 of the window opening device EY1 is "3". Furthermore, the following assumes that the reference value AZ0 is "3".

[0271] In this case, the device determination unit 63 selects a window opening device EY1 as the environmental control device E to operate in the agricultural greenhouse 1, if the difference between the internal temperature AN1 and the target temperature AP1 is greater than the temperature reference value AR1 and less than or equal to the temperature tolerance value AL1, that is, if the internal temperature AN1 is within the environmental tolerance range. The window opening device EY1 has a temperature rise capacity AZ1 that is less than or equal to the reference value AZ0. Furthermore, if the difference between the internal temperature AN1 and the target temperature AP1 is greater than the temperature tolerance value AL1, that is, if the internal temperature AN1 is not within the environmental tolerance range, the device determination unit 63 selects a heating device EX1 with a temperature rise capacity AZ1 greater than the standard value AZ0 as the environmental control device E to operate in the agricultural greenhouse 1.

[0272] As described above, in this modified example, the device determination unit 63 selects the environmental control device E to operate in the agricultural greenhouse 1 based on the individual standard value ARw and the individual allowable value ALw determined according to the cultivation mode. Therefore, according to this modified example, it becomes possible to easily cultivate plants in the agricultural greenhouse 1 based on the cultivation policy indicated by the cultivation mode.

[0273] <Variation 3> In the embodiments and modified examples 1 and 2 described above, the device determination unit 63 has been shown as an example of determining whether or not to operate the environmental adjustment device EY in the agricultural greenhouse 1 based on the device candidate information JK[k] or the physical quantity correction capability information JZz. However, the present invention is not limited to such embodiments. For example, if the difference between the individual internal environment value ANw indicated by the individual internal environment information JNw and the individual target value APw indicated by the individual target value information JPw is greater than the difference between the individual external environment value AGw indicated by the individual external environment information JGw and the individual target value APw indicated by the individual target value information JPw, the device determination unit 63 may decide to operate the environmental adjustment device EY among the multiple environmental adjustment devices EY installed in the agricultural greenhouse 1 that has a physical quantity correction capability AZz that brings the individual internal environment value ANw closer to the individual target value APw.

[0274] <Modification 4> In the embodiments and modifications 1 to 3 described above, the device control unit 64 has been shown to have three cultivation modes when controlling a plurality of environmental control devices E: a quality-priority mode, a cost-priority mode, and a balanced mode, as well as two combined cultivation modes: a quality-focused combined cultivation mode and a cost-focused combined cultivation mode, which are combinations of two of these three cultivation modes. However, the present invention is not limited to these embodiments. For example, the device control unit 64 may include cultivation modes other than those described above as cultivation modes when controlling a plurality of environmental control devices E.

[0275] In this modified example, it is assumed that when the device control unit 64 controls multiple environmental adjustment devices E, there are cultivation modes that include a quality-priority mode, a cost-priority mode, a balance mode, a natural cultivation mode, a pest and disease prevention mode, and a combined cultivation mode that combines two or more of these five cultivation modes.

[0276] Of these, the natural cultivation mode is a cultivation mode in which plants are grown in agricultural greenhouse 1 based on a cultivation policy that involves minimizing the use of pesticides and insecticides and cultivating plants in an internal environment that is close to the natural environment. Furthermore, the pest and disease prevention mode is a cultivation mode in which plants are grown in agricultural greenhouse 1 based on a cultivation policy that involves the appropriate use of pesticides and insecticides to prevent the occurrence of pests and diseases in the plants grown in agricultural greenhouse 1 as much as possible.

[0277] In this modified example, the quality-prioritizing mode may be a cultivation mode in which plants are cultivated in the agricultural greenhouse 1 based on a cultivation policy that prioritizes high quality of plants cultivated in the agricultural greenhouse 1 over some or all of the following: low cost of cultivating plants in the agricultural greenhouse 1, realization of an internal environment close to the natural environment in the agricultural greenhouse 1, and prevention of pests and diseases in the plants cultivated in the agricultural greenhouse 1. Furthermore, in this modified example, the cost-prioritizing mode may be a cultivation mode in which plants are cultivated in the agricultural greenhouse 1 based on a cultivation policy that prioritizes low costs for cultivating plants in the agricultural greenhouse 1 over some or all of the following: high quality of plants cultivated in the agricultural greenhouse 1, realization of an internal environment close to the natural environment in the agricultural greenhouse 1, and prevention of pests and diseases in the plants cultivated in the agricultural greenhouse 1. Furthermore, in this modified example, the balance mode may be a cultivation mode in which plants are cultivated in the agricultural greenhouse 1 based on a cultivation policy that achieves at least two of the following: high quality of plants cultivated in the agricultural greenhouse 1, low cost of cultivating plants in the agricultural greenhouse 1, realization of an internal environment in the agricultural greenhouse 1 that is close to the natural environment, and prevention of pests and diseases in plants cultivated in the agricultural greenhouse 1.

[0278] <Modification 5> In the embodiments and modifications 1 to 4 described above, the environmental adjustment system 2 was described as comprising an internal environmental adjustment system 21 including six internal environmental adjustment devices EX, which consist of a heating device EX1, a cooling device EX2, a humidifier EX3, a dehumidifier EX4, a carbon dioxide supply device EX5, and a lighting device EX6, and an inter-environmental adjustment system 22 including three inter-environmental adjustment devices EY, which consist of a window opening device EY1, a ventilation device EY2, and a light-shielding device EY3. However, the present invention is not limited to these embodiments. The environmental adjustment system 2 may also comprise internal environmental adjustment devices EX different from the six internal environmental adjustment devices EX described above, or it may also comprise inter-environmental adjustment devices EY different from the three inter-environmental adjustment devices EY described above. For example, the environmental control system 2 may include an irrigation device that supplies water to plants grown in the agricultural greenhouse 1, or it may include a soil temperature control device that controls the temperature of the soil in the internal space SP of the agricultural greenhouse 1. In addition, in the above-described embodiments and Modifications 1 to 4, the internal environment measurement system 31 of the environment measurement system 3 has been described by way of example as including the internal environment temperature sensor SX1, the internal environment humidity sensor SX2, the internal environment carbon dioxide concentration sensor SX3, and the internal environment illuminance sensor SX4. However, the present invention is not limited to such an aspect. For example, the internal environment measurement system 31 may include a soil temperature sensor that detects the temperature of the soil in the internal space SP of the agricultural greenhouse 1. Further, the internal environment measurement system 31 may include a soil moisture sensor that detects the amount of moisture in the soil in the internal space SP within the agricultural greenhouse 1.

[0279] <C. Supplementary Note> From the descriptions of the above-described embodiments and modifications, the present invention is understood as follows. For ease of understanding of each aspect, reference numerals in the drawings are appended in parentheses for convenience below, but this is not intended to limit the present invention to the illustrated aspects.

[0281] According to this aspect, since the device control unit adjusts the plurality of environment adjustment devices according to the cultivation mode, it is possible to easily perform plant cultivation based on the cultivation policy indicated by the cultivation mode.

[0282] <Supplementary Note 2> A program according to one aspect of the present invention is characterized by comprising an acquisition unit (e.g., a cultivation-related information acquisition unit 61) that acquires selection information (e.g., selection mode information JC) indicating a cultivation mode selected from a plurality of cultivation modes for plants to be cultivated in a greenhouse for plant cultivation, and a device control unit (e.g., a device control unit 64) that controls a plurality of environmental adjustment devices for adjusting the environment inside the greenhouse according to the cultivation mode indicated by the selection information.

[0283] According to this embodiment, the device control unit adjusts multiple environmental control devices according to the cultivation mode, making it easy to cultivate plants based on the cultivation policy indicated by the cultivation mode.

[0284] <Note 3> A program according to another aspect of the present invention is the program described in Appendix 1 or 2, characterized in that the plurality of cultivation modes include a first cultivation mode (e.g., a quality-priority mode) that cultivates the plants prioritizing high quality, and a second cultivation mode (e.g., a cost-priority mode) that cultivates the plants prioritizing low cost for cultivation.

[0285] According to this embodiment, when cultivating plants in a greenhouse, it is possible to easily perform two types of cultivation: one based on a cultivation policy that prioritizes high plant quality, and another based on a cultivation policy that prioritizes low cultivation costs.

[0286] <Note 4> A program according to another aspect of the present invention is a program as described in Appendix 1 or 2, characterized in that the plurality of cultivation modes include a first cultivation mode in which the plants are cultivated prioritizing the high quality of the plants over the low cost of cultivating the plants, and a second cultivation mode in which the plants are cultivated prioritizing the low cost of cultivating the plants over the high quality of the plants.

[0287] According to this embodiment, when cultivating plants in a greenhouse, it is possible to easily perform two types of cultivation: one based on a cultivation policy that prioritizes high plant quality, and another based on a cultivation policy that prioritizes low cultivation costs.

[0288] <Note 5> A program according to another aspect of the present invention is a program described in appendices 1 to 4, characterized in that the plurality of cultivation modes include a third cultivation mode (e.g., a balanced mode) which cultivates the plants in such a way that both high quality of the plants and low cost of cultivating the plants are achieved.

[0289] According to this embodiment, when cultivating plants in a greenhouse, it is possible to easily cultivate plants based on a cultivation policy that achieves both high plant quality and low cultivation costs.

[0290] <Note 6> Another aspect of the present invention is a program described in appendices 1 to 5, characterized in that when two or more cultivation modes (for example, a combined cultivation mode) are selected from the plurality of cultivation modes, the plurality of environmental adjustment devices are controlled according to the two or more cultivation modes.

[0291] According to this embodiment, when cultivating plants in a greenhouse, it is possible to easily cultivate plants based on multiple cultivation policies.

[0292] <Note 7> Another aspect of the present invention is the program described in Appendix 6, characterized in that, when one cultivation mode (e.g., main cultivation mode) is selected from among the plurality of cultivation modes and then another cultivation mode (e.g., secondary cultivation mode) is selected, the plurality of environmental control devices are controlled such that the one cultivation mode takes precedence over the other cultivation modes.

[0293] According to this embodiment, when cultivating plants in a greenhouse, it is possible to easily cultivate plants while prioritizing the cultivation policy for one cultivation mode, while also taking into account the cultivation policies for other cultivation modes.

[0294] <Note 8> A program according to another aspect of the present invention is a program described in appendices 1 to 7, wherein the plurality of cultivation modes include a first cultivation mode for cultivating the plants prioritizing high quality, a second cultivation mode for cultivating the plants prioritizing low cost of cultivation, and a third cultivation mode for cultivating the plants in a manner that achieves both high quality and low cost of cultivation, and the device control unit, when two or more cultivation modes are selected from the plurality of cultivation modes, selects the two or more cultivation modes (for example, a quality-focused combination cultivation mode or a cost-focused combination cultivation mode). The present invention is characterized in that, when the plurality of environmental adjustment devices are controlled according to (D), and the device control unit controls the plurality of environmental adjustment devices according to the third cultivation mode, the degree of priority given to the quality of the plants in relation to the cultivation of the plants (for example, the ratio of the quality evaluation value VH[k] to the balance evaluation value VB[k]) is different from the degree of priority given to the quality of the plants in relation to the cultivation of the plants (for example, the ratio of the quality evaluation value VH[k] to the quality-focused combination evaluation value VBH[k] or the cost-focused combination evaluation value VBC[k]) when the device control unit controls the plurality of environmental adjustment devices according to the two or more cultivation modes.

[0295] According to this embodiment, when cultivating plants in a greenhouse, in addition to the first cultivation mode, the second cultivation mode, and the third cultivation mode, multiple environmental control devices can be adjusted according to two or more cultivation modes selected from the first cultivation mode, the second cultivation mode, and the third cultivation mode. Therefore, according to this embodiment, for example, when cultivating plants in a greenhouse, it becomes possible to cultivate plants in the greenhouse using a wider variety of cultivation strategies compared to an embodiment in which multiple environmental control devices are adjusted according to one cultivation mode selected from the first cultivation mode, the second cultivation mode, and the third cultivation mode.

[0296] <Note 9> A program according to another aspect of the present invention is the program described in Appendix 8, characterized in that, after one of the cultivation modes, the first cultivation mode and the second cultivation mode, is selected from the plurality of cultivation modes, and then the other cultivation mode between the first cultivation mode and the second cultivation mode is selected, two or more cultivation modes are selected, and the device control unit controls the plurality of environmental control devices such that, compared to the case where the device control unit controls the plurality of environmental control devices according to the third cultivation mode, the plants are cultivated with priority given to either high quality of the plants or low cost of cultivation over the other.

[0297] According to this embodiment, when cultivating plants in a greenhouse, compared to an embodiment in which multiple environmental control devices are adjusted according to one cultivation mode selected from a first cultivation mode, a second cultivation mode, and a third cultivation mode, it becomes possible to more finely adjust either the degree to which high plant quality is prioritized or the degree to which low plant cultivation costs are prioritized.

[0298] <Note 10> A program according to another aspect of the present invention is the program described in Appendix 8 or 9, characterized in that, when two or more cultivation modes are selected, such that the first cultivation mode is selected from the plurality of cultivation modes and then the second cultivation mode is selected, the device control unit controls the plurality of environmental control devices so that, compared to the case where the device control unit controls the plurality of environmental control devices according to the third cultivation mode, the plants are cultivated prioritizing the high quality of the plants over the low cost of cultivating the plants.

[0299] According to this embodiment, when cultivating plants in a greenhouse, it is possible to adjust the degree to which high quality of the plants is prioritized more finely compared to an embodiment in which multiple environmental control devices are adjusted according to one cultivation mode selected from the first cultivation mode, the second cultivation mode, and the third cultivation mode.

[0300] <Note 11> A program according to another aspect of the present invention is a program described in appendices 8 to 10, characterized in that, when two or more cultivation modes are selected, such that the second cultivation mode is selected from the plurality of cultivation modes and then the first cultivation mode is selected, the device control unit controls the plurality of environmental control devices so that the plants are cultivated prioritizing low cost over high quality of the plants, compared to when the device control unit controls the plurality of environmental control devices according to the third cultivation mode.

[0301] According to this embodiment, when cultivating plants in a greenhouse, it is possible to adjust the degree to which the cost of plant cultivation is prioritized more finely compared to an embodiment in which multiple environmental control devices are adjusted according to one cultivation mode selected from the first cultivation mode, the second cultivation mode, and the third cultivation mode.

[0302] <Note 12> A program according to another aspect of the present invention is a program described in appendices 1 to 11, characterized in that the device control unit controls the plurality of environmental control devices in accordance with the detection results (e.g., individual internal environment value ANw) of a sensor (e.g., internal environment sensor SXw) for detecting physical quantities relating to the environment inside the greenhouse and the target values ​​(e.g., individual target value APw) of the physical quantities in the cultivation of the plants.

[0303] According to this embodiment, when cultivating plants in a greenhouse, it is possible to maintain physical quantities related to the internal environment of the greenhouse in a state close to target values ​​suitable for plant cultivation.

[0304] <Note 13> Another aspect of the present invention is a program as described in Appendix 12, characterized in that the target value of the physical quantity is determined according to the selected cultivation mode.

[0305] According to this embodiment, the internal environment of the greenhouse can be adjusted for each cultivation mode according to the cultivation policy corresponding to each cultivation mode.

[0306] <Note 14> A program according to another aspect of the present invention is the program described in Appendix 12 or 13, characterized in that the device control unit operates one or more environmental adjustment devices among the plurality of environmental adjustment devices that are related to the physical quantity to be detected by the sensor when the degree of difference between the detection result of the sensor and the target value is greater than a threshold (e.g., individual reference value ARw) determined according to the selected cultivation mode.
