[0022] <Current Situation> In recent years, structures in which plants are cultivated have come into use. To maintain a predetermined environment (temperature, humidity, etc.) inside the structure where the plants are cultivated, air conditioning of the inside of the structure is carried out. This has resulted in the problem that a large amount of energy is used to air condition the inside of the structure. Below, an embodiment of an example of a structure system that contributes to solving the above problem will be described.

[0023] <First embodiment> (1) Overall configuration The overall configuration of a structure system 1 according to the first embodiment will be described. FIG. 1 is a schematic diagram showing the overall configuration of the structure system 1. The structure system 1 mainly includes a greenhouse 10, an air conditioner 11, and a control device 16. In the first embodiment, front means the X direction, rear means the negative X direction, left means the negative Z direction, right means the Z direction, down means the negative Y direction, and up means the Y direction. Height is the distance from the soil S in the Y direction.

[0024] (1-1) Greenhouse The green house 10 is a structure in which a framework is constructed and the top is covered with vinyl or the like in order to cultivate plants P. The green house 10 is a non-variable structure whose internal volume cannot be changed by operation. Plants P are cultivated inside the green house 10.

[0025] The structure system 1 may include a greenhouse (such as a glass greenhouse or a plastic film greenhouse) instead of the greenhouse 10. The greenhouse 10 may be a building (a structure fixed to the land that has a roof and pillars or walls) or may not be a building. The structure system 1 does not have to include the greenhouse 10.

[0026] The interior of the greenhouse 10 is mainly provided with a structure 100A and a structure 100B. The structures 100A and 100B divide the interior of the greenhouse 10 into an interior I1 of the structure 100A, an interior I2 of the structure 100B, and a space I3 outside the structures 100A and 100B and inside the greenhouse 10. Details of the structures 100A and 100B will be described later. The greenhouse 10 mainly has an entrance / exit 101, a passage 102, and one or more lights (not shown).

[0027] (1-1-1) Entrance / Exit The entrance / exit 101 is an entrance through which people or equipment that will be performing agricultural work move from the outside of the greenhouse 10 to the inside of the greenhouse 10. The entrance / exit 101 is also an exit through which people or equipment that have completed agricultural work move from the inside of the greenhouse 10 to the outside of the greenhouse 10. The entrance / exit 101 may have a structure that can be opened and closed (an opening), or may have an open structure (an opening). The greenhouse 10 may have multiple entrances / exits 101.

[0028] Agricultural work is work performed by people or machines on plants P. Examples of agricultural work include sowing work, which is planting seeds or seedlings of plants P, cultivation work, which is work performed to grow plants P (watering, spraying pesticides, pruning, spreading fertilizer, insect repellent, etc.), harvesting work, which is harvesting all or part of plants P, soil work, which is work to prepare or till soil S, nutrient solution work, which is work to store or replace nutrient solution, and other agricultural work.

[0029] (1-1-2) Pathway The path 102 is a path for people or equipment when agricultural work is being carried out.

[0030] (1-2) Air Conditioner The air conditioner 11 conditions the air in the interiors I1 and I2. Examples of air conditioning include cooling, heating, ventilation, air purification, dehumidification, and humidification. The air conditioner 11 communicates with the interior I1 via a hose 17. The air conditioner 11 also communicates with the interior I2 via a hose (not shown) different from the hose 17. Air conditioned by the air conditioner 11 is supplied to the interiors I1 and I2 via the hose 17 or the like. Note that the location where the air conditioner 11 is installed is not limited to the outside of the greenhouse 10. The air conditioner 11 may be installed in at least one of the interiors I1, I2, and I3.

[0031] (1-3) Control Device The control device 16 mainly controls the structure 100A, the structure 100B, and the air conditioner 11. The control device 16 is connected to the structure 100A, the structure 100B, and the air conditioner 11 by wire or wirelessly. Details of the control device 16 will be described later. The location where the control device 16 is installed is not limited to the outside of the greenhouse 10. The control device 16 may be installed in at least one of the interior I1, the interior I2, and the space I3. The functions of the control device 16 may be realized on a server or the cloud. The control device 16 may be connected to structures installed in multiple greenhouses 10.

[0032] (2) Detailed Configuration (2-1) Structure 100A and Structure 100B The detailed configuration of the structure 100A and the structure 100B will be described. The structure 100A is a variable structure in which the volume of the interior I1 can be changed by the operation of the structure 100A. The structure 100B is a variable structure in which the volume of the interior I2 can be changed by the operation of the structure 100B. The structures of the structure 100A and the structure 100B are roughly symmetrical with respect to a plane extending in the Y direction and the Z direction. The function of the structure 100A is similar to that of the structure 100B. The structure and function of the structure 100A will be described below.

[0033] 2 is a diagram showing the detailed configuration of the structure 100A. The structure 100A mainly includes a first front movable wall 111, a second front movable wall 112, a left fixed wall 121, a left movable wall 122, a right fixed wall 131, a right movable wall 132, a rear fixed wall 141, a rear movable wall 142, a ceiling 150, a first guide rail 151A, a second guide rail 151B, a third guide rail 151C, and a fourth guide rail 151D.

[0034] Examples of the configurations of the first front movable wall 111, the second front movable wall 112, the left fixed wall 121, the left movable wall 122, the right fixed wall 131, the right movable wall 132, the rear fixed wall 141, the rear movable wall 142, and the ceiling 150 include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0035] At least one of the first front movable wall 111, the second front movable wall 112, the left fixed wall 121, the left movable wall 122, the right fixed wall 131, the right movable wall 132, the rear fixed wall 141, the rear movable wall 142, and the ceiling 150 may be configured to include transparent or translucent vinyl, glass, or plastic film so that light from the lighting in space I3 is transmitted to the interior I1.

[0036] The left fixed wall 121, the right fixed wall 131, and the rear fixed wall 141 are fixed to the soil S and are provided in a direction generally perpendicular to the soil S (Y direction). The left fixed wall 121 is provided with an opening 123 that communicates with the hose 17. Air conditioned by the air conditioner 11 is supplied to the interior I1 through the opening 123.

[0037] The ceiling 150 is generally parallel to the soil S. The second front movable wall 112, the left movable wall 122, the right movable wall 132, and the rear movable wall 142 are connected to the ceiling 150 at the four corners of the ceiling 150. Therefore, the second front movable wall 112, the left movable wall 122, the right movable wall 132, the rear movable wall 142, and the ceiling 150 form a single member.

[0038] The space surrounded by the soil S, the first front movable wall 111, the left fixed wall 121, the right fixed wall 131, and the rear fixed wall 141 is covered from above by a member formed by the second front movable wall 112, the left movable wall 122, the right movable wall 132, the rear movable wall 142, and the ceiling 150. The interior I1 is isolated from the outside of the structure 100A (space I3) by the structure 100A.

[0039] The second front movable wall 112 is located in front (X direction) of the first front movable wall 111 and is generally perpendicular to the soil S. The left movable wall 122 is located to the left (negative Z direction) of the left fixed wall 121 and is generally perpendicular to the soil S. The right movable wall 132 is located to the right (Z direction) of the right fixed wall 131 and is generally perpendicular to the soil S. The rear movable wall 142 is located behind (negative X direction) the rear fixed wall 141 and is generally perpendicular to the soil S.

[0040] The first guide rail 151A, the second guide rail 151B, the third guide rail 151C, and the fourth guide rail 151D are arranged in a direction generally perpendicular to the soil S.

[0041] A plant P is cultivated in the interior I1. Soil S in which the plant P can be planted or a nutrient solution (not shown) in which the plant P can be soaked is stored in the interior I1. In the interior I1, the plant P is planted in the soil S or soaked in the nutrient solution. Note that cultivating a plant P in the interior I1 does not mean that the plant P is always present in the interior I1. After the plant P is harvested, there may be cases where the plant P is not present in the interior I1. Furthermore, even if the plant P is present in the interior I1, there may be cases where the plant P has just been planted, and therefore the plant P has not yet germinated, or the plant P cannot be seen with the naked eye in the interior I1.

[0042] The left fixed wall 121, the right fixed wall 131, and the rear fixed wall 141 are non-movable components. The first front movable wall 111, the second front movable wall 112, the left movable wall 122, the right movable wall 132, the rear movable wall 142, and the ceiling 150 are movable components. Below, a description will be given of a variable method that can be adopted for the structure 100A. The variable method is a method of changing the internal volume of the structure by moving the structure.

[0043] (2-1-1) Variable Method (2-1-1-1) Rail Method The rail method is a method of changing the internal volume of a structure by sliding components of the structure (which are roughly parallel to the ground) on multiple guide rails that are installed roughly perpendicular to the ground.

[0044] 3, 4, and 5 are diagrams showing an example of the rail method. The first guide rail 151A, the second guide rail 151B, the third guide rail 151C, and the fourth guide rail 151D are installed in a direction (Y direction) generally perpendicular to the ground (soil S). The ceiling 150 is generally parallel to the soil S. The ceiling 150 is guided by the first guide rail 151A, the second guide rail 151B, the third guide rail 151C, and the fourth guide rail 151D and is installed so as to be able to slide in the Y direction or the negative Y direction (the direction in which the first guide rail 151A, the second guide rail 151B, the third guide rail 151C, and the fourth guide rail 151D extend).

[0045] The corners of the ceiling 150 are connected to the second front movable wall 112, the left movable wall 122, the right movable wall 132, and the rear movable wall 142. Therefore, the second front movable wall 112, the left movable wall 122, the right movable wall 132, and the rear movable wall 142 move in the Y direction or the negative Y direction, just like the ceiling 150.

[0046] For example, when the ceiling 150 is slid in the Y direction from the state of the structure 100A in Fig. 3, the state can change to the state of the structure 100A in Fig. 4. When the ceiling 150 is further slid in the Y direction from the state of the structure 100A in Fig. 4, the state can change to the state of the structure 100A in Fig. 5.

[0047] For example, when the ceiling 150 is slid in the negative Y direction from the state of the structure 100A in Fig. 5, the state can change to the state of the structure 100A in Fig. 4. When the ceiling 150 is further slid in the negative Y direction from the state of the structure 100A in Fig. 4, the state can change to the state of the structure 100A in Fig. 3.

[0048] (2-1-1-2) Other Methods The method for changing the structure 100A may be any other changeable method conceivable by a person skilled in the art and is not limited to the above example. Note that at least one of the left fixed wall 121, the right fixed wall 131, and the rear fixed wall 141 may be a movable component. For example, the internal volume of the structure may be changed by sliding the components of the structure (which are arranged in a generally vertical direction relative to the ground) in the X direction or the negative X direction on multiple guide rails arranged in a generally horizontal direction (X direction) on the ground. The internal volume of the structure may be changed by sliding the components of the structure (which are arranged in a generally vertical direction relative to the ground) in the Z direction or the negative Z direction on multiple guide rails arranged in a generally horizontal direction (Z direction) on the ground.

[0049] (2-1-2) Aspect of the structure 100A when agricultural work is being performed The following describes the aspect of the structure 100A when agricultural work is being performed. When agricultural work is being performed, the aspect of the structure 100A changes so as to ensure the space necessary for the agricultural work.

[0050] 6 is a diagram showing an example of the structure 100A when agricultural work is being performed. When agricultural work is being performed, the ceiling 150 slides in the Y direction, and the first front movable wall 111 also slides in the Y direction while being guided by the first guide rail 151A and the second guide rail 151B. An aisle 102 exists on the front (X direction) side of the structure 100A. The front side of the structure 100A is connected to the aisle 102. This allows people or equipment to perform agricultural work.

[0051] When agricultural work is performed, other aspects of the structure 100A that a person skilled in the art can imagine may be realized, and are not limited to the above example. The distance that the ceiling 150 and the first front movable wall 111 slide in the Y direction may vary based on the space required for agricultural work. The first guide rails 151A may be two rows of guide rails used by the ceiling 150 and the first front movable wall 111, respectively. In this case, the second guide rails 151B are also two rows of guide rails used by the ceiling 150 and the first front movable wall 111, respectively.

[0052] (2-2) Control Device A detailed configuration of the control device 16 will be described. Fig. 7 is a functional block diagram of the control device 16. The control device 16 mainly includes an information processing device 161, a structure control unit 162, and an air conditioning control unit 163.

[0053] (2-2-1) Information Processing Device The information processing device 161 mainly includes a receiving unit 1613 , an action identifying unit 1614 , and a storage unit 1615 .

[0054] (2-2-1-1) Reception Unit The reception unit 1613 receives spatial information from a user or an external device (not shown). The reception unit 1613 may receive spatial information from outside via a network using real-time processing or badge processing. The reception unit 1613 records the received spatial information in the storage unit 1615. The spatial information is information indicating the required space N. The required space N will be described below.

[0055] (2-2-1-1-1) Required Space Required space N is the space required in interiors I1 and I2 due to the growth of plant P in one structure control cycle. A structure control cycle refers to the period from the control of structures 100A and 100B by the structure control unit 162 to the next control of structures 100A and 100B by the structure control unit 162. Securing required space N means securing a space equal to required space N or a space including required space N in a three-dimensional coordinate system.

[0056] An example of the required space N will be described. The depth (length in the X direction) of the required space N is the same as the depth of the interior I1. The width (length in the Z direction) of the required space N is the same as the width of the interior I1. The bottom surface of the required space N (a surface extending in the X and Z directions and located below (in the minus Y direction)) is parallel to the soil S. The top surface of the required space N (a surface extending in the X and Z directions and located above (in the Y direction)) is parallel to the soil S. The height of the bottom surface of the required space N is the same as the height of the plant P at the current time (the time when the required space N is identified). The height of the top surface of the required space N is the same as the height of the plant P one structure control cycle from the current time. The height of the plant P one structure control cycle after the current time is the sum of the height of the plant P at the current time and the change in the height of the plant P over one structure control cycle. The height of the upper surface of the required space N may be a value obtained by adding the height of the plant P one structure control cycle from the current time to an extra height (marginal height). Examples of the extra height include, but are not limited to, 3 cm to 10 cm.

[0057] The plant P grows over time. As time passes, the height of the plant P increases. For example, the plant P grows approximately 2 cm per day until the growth end date (the date when the plant P finishes growing). The structure control cycle is assumed to be 15 days. The growth end date is assumed to be 60 days. In other words, from the sowing date (the date when the plant P is sown) to the day 60 days after the sowing date, the change in height of the plant P per day is 2 cm. After the day 60 days after the sowing date, the change in height of the plant P per day is 0 cm. Based on the above assumptions, a specific example of the required space N will be described.

[0058] Figures 8, 9, 10, 11, and 12 are diagrams showing examples of the required space N. The state of the structure 100A and plant P in Figure 8 is assumed to be the state on the sowing day. Because the plant P has not yet germinated, the height of the plant P at the current time (the sowing day) is approximately 0 cm. Because the plant P has not yet germinated, the plant P is not shown in Figure 8. The height of the plant P one structure control cycle from the current time will be 30 cm, which is the sum of 0 cm, which is the height of the plant P at the current time, and 30 cm, which is the change in the height of the plant P over 15 days. Therefore, the height of the bottom surface of the required space N is 0 cm. The height of the top surface of the required space N is 30 cm.

[0059] The state of the structure 100A and plant P in Figure 9 is assumed to be that of the day 15 days after sowing. The height of the plant P at the current time (15 days after sowing) is approximately 30 cm. The height of the plant P one structure control cycle from the current time will be 60 cm, which is the sum of the current height of the plant P (30 cm) and the change in height of the plant P over 15 days (30 cm). Therefore, the height of the bottom surface of the required space N is 30 cm. The height of the top surface of the required space N is 60 cm.

[0060] The state of the structure 100A and plant P in Figure 10 is assumed to be that of the plant P 30 days after sowing. The height of the plant P at the current time (30 days after sowing) is approximately 60 cm. The height of the plant P one structure control cycle from the current time will be 90 cm, which is the sum of the current height of the plant P (60 cm) and the change in height of the plant P over 15 days (30 cm). Therefore, the height of the bottom surface of the required space N is 60 cm. The height of the top surface of the required space N is 90 cm.

[0061] The state of the structure 100A and plant P in Figure 11 is assumed to be that of the day 45 days after sowing. The height of the plant P at the current point in time (45 days after sowing) is approximately 90 cm. The height of the plant P one structure control cycle from the current point in time will be 120 cm, which is the sum of 90 cm, the height of the plant P at the current point in time, and 30 cm, the change in height of the plant P over 15 days. Therefore, the height of the bottom surface of the required space N is 90 cm. The height of the top surface of the required space N is 120 cm.

[0062] The state of the structure 100A and plant P in Figure 12 is assumed to be that 60 days after sowing. The height of the plant P at the current point in time (60 days after sowing) is approximately 120 cm. The plant P has finished growing. The height of the plant P one structure control cycle from the current point in time will be 120 cm, which is the sum of 120 cm, the height of the plant P at the current point in time, and 0 cm, the change in height of the plant P over 15 days. Therefore, the height of the bottom surface of the required space N is 120 cm. The height of the top surface of the required space N is 120 cm. The required space N is a space with a height from the bottom surface to the top surface of 0 cm. In other words, the required space N does not exist.

[0063] (2-2-1-1-2) Spatial Information For example, the spatial information is information that associates a date with a required space N. Fig. 13 is a diagram showing an example of spatial information.

[0064] (2-2-1-2) Motion Identification Unit The motion identification unit 1614 identifies motion information based on the spatial information stored in the storage unit 1615. The motion identification unit 1614 also records the identified motion information in the storage unit 1615. The motion information is information indicating the motion of the structures 100A and 100B to secure the required space N. During this motion, the isolation of the interiors I1 and I2 from the outside (space I3) of the structures 100A and 100B is maintained.

[0065] An example of the processing of the action identification unit 1614 will be described below. The action identification unit 1614 reads the spatial information stored in the storage unit 1615. The action identification unit 1614 identifies a date similar to the current date from among the dates included in the spatial information. The action identification unit 1614 identifies the necessary space N associated with the identified date. The action identification unit 1614 compares the three-dimensional coordinates of the identified necessary space N with the three-dimensional coordinates of the structure 100A.

[0066] The movement identification unit 1614 identifies the movement of the structure 100A (movement of the ceiling 150) that ensures the required space N. The ceiling 150 needs to be positioned above the upper surface of the required space N. The movement identification unit 1614 identifies the movement of the ceiling 150 so that the height of the ceiling 150 is higher than the height of the upper surface of the required space N. The movement identification unit 1614 associates the identified movement of the structure 100A with the current date to identify movement information. The movement information is information that associates the date with the movement of the ceiling 150. The movement identification unit 1614 records the identified movement information in the storage unit 1615.

[0067] Below, a specific example of the processing of the action identification unit 1614 when the spatial information is the spatial information of Fig. 13 will be described. Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, and Fig. 21 are diagrams showing examples of aspects of the structure 100A.

[0068] FIG. 15 is a diagram showing an example of the state of the structure 100A on the sowing date. The height of the ceiling 150 on the sowing date is assumed to be 60 cm. On the sowing date, the action identification unit 1614 identifies the required space N in FIG. 8 associated with the sowing date. The action identification unit 1614 compares the three-dimensional coordinates of the required space N in FIG. 8 with the three-dimensional coordinates of the structure 100A. The height of the ceiling 150 (60 cm) is higher than the height of the top surface of the required space N (30 cm). The action identification unit 1614 identifies that the required space N is secured in the interior I1. The action identification unit 1614 identifies action information by associating the sowing date with the fact that the ceiling 150 does not operate.

[0069] FIG. 16 is a diagram showing an example of the state of the structure 100A on the day 15 days after the sowing date. Assume that the height of the ceiling 150 on the day 15 days after the sowing date is 60 cm. On the day 15 days after the sowing date, the operation identification unit 1614 identifies the required space N in FIG. 9 associated with the day 15 days after the sowing date. The operation identification unit 1614 compares the three-dimensional coordinates of the required space N in FIG. 9 with the three-dimensional coordinates of the structure 100A. The height of the ceiling 150 (60 cm) is the same as the height of the top surface of the required space N (60 cm). The operation identification unit 1614 identifies that the required space N has been secured in the interior I1. The operation identification unit 1614 identifies operation information by associating the day 15 days after the sowing date with the fact that the ceiling 150 does not operate.

[0070] FIG. 17 is a diagram showing an example of the structure 100A on the day 30 days after the sowing date. Assume that the height of the ceiling 150 on the day 30 days after the sowing date is 60 cm. On the day 30 days after the sowing date, the action identification unit 1614 identifies the required space N in FIG. 10 associated with the day 30 days after the sowing date. The action identification unit 1614 compares the three-dimensional coordinates of the required space N in FIG. 10 with the three-dimensional coordinates of the structure 100A. The height of the ceiling 150 (60 cm) is approximately 30 cm lower than the height of the top surface of the required space N (90 cm). The action identification unit 1614 identifies that the ceiling 150 moves 30 cm in the Y direction to secure the required space N in the interior I1. The action identification unit 1614 identifies action information by associating the day 30 days after the sowing date with the fact that the ceiling 150 moves 30 cm in the Y direction.

[0071] FIG. 19 is a diagram showing an example of the structure 100A on the day 45 days after sowing. Assume that the height of the ceiling 150 on the day 45 days after sowing is 90 cm. On the day 45 days after sowing, the action identification unit 1614 identifies the required space N in FIG. 11 associated with the day 45 days after sowing. The action identification unit 1614 compares the three-dimensional coordinates of the required space N in FIG. 11 with the three-dimensional coordinates of the structure 100A. The height of the ceiling 150 (90 cm) is approximately 30 cm lower than the height of the top surface of the required space N (120 cm). The action identification unit 1614 identifies that the ceiling 150 moves 30 cm in the Y direction to ensure the required space N in the interior I1. The action identification unit 1614 identifies action information by associating the day 45 days after sowing with the fact that the ceiling 150 moves 30 cm in the Y direction.

[0072] FIG. 21 is a diagram showing an example of the state of the structure 100A on the day 60 days after the sowing date. Assume that the height of the ceiling 150 on the day 60 days after the sowing date is 120 cm. On the day 60 days after the sowing date, the operation identification unit 1614 identifies that there is no necessary space N associated with the day 60 days after the sowing date. Because there is no necessary space N, the operation identification unit 1614 does not need to operate the ceiling 150. The operation identification unit 1614 identifies operation information by associating the day 60 days after the sowing date with the fact that the ceiling 150 will not operate.

[0073] 14 is a diagram showing an example of the motion information. The motion identification unit 1614 identifies the motion information in FIG. 14 through the above process.

[0074] The motion identification unit 1614 may identify motion information relating to a future date in advance. For example, on the sowing date, the motion identification unit 1614 may identify motion information relating to at least one of the following dates: 15 days after the sowing date, 30 days after the sowing date, 45 days after the sowing date, and 60 days after the sowing date.

[0075] (2-2-1-3) Storage Unit The storage unit 1615 stores the spatial information received by the reception unit 1613. The storage unit 1615 also stores the motion information identified by the motion identification unit 1614. Examples of the storage unit 1615 include a hard disk drive (HDD) and a solid state drive (SSD).

[0076] (2-2-2) Structure Control Unit The structure control unit 162 controls the structures 100A and 100B so that the structures 100A and 100B secure the required space N through their operations.

[0077] An example of the processing of the structure control unit 162 will be described below. The structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 identifies a date similar to the current date from among the dates included in the operation information. The structure control unit 162 identifies the operation of the structure 100A (operation of the ceiling 150) associated with the identified date. The structure control unit 162 controls the structure 100A based on the identified operation of the structure 100A.

[0078] Below, a specific example of the processing of the structure control unit 162 when the operation information is the operation information of FIG. 14 and the structure control period is 15 days will be described. The state of the structure 100A on the sowing date is the state of the structure 100A of FIG. 15. On the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The operation information associates the sowing date with the fact that the ceiling 150 will not operate. Therefore, the structure control unit 162 does not operate the ceiling 150. In other words, the structure control unit 162 controls the structure 100A so that it does not operate.

[0079] The state of the structure 100A on the day 15 days after the sowing date is the state of the structure 100A in FIG. 16 . On the day 15 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 15 days after the sowing date is associated with the fact that the ceiling 150 will not operate. Therefore, the structure control unit 162 does not operate the ceiling 150. In other words, the structure control unit 162 controls the structure 100A so that it does not operate.

[0080] The state of the structure 100A 30 days after the sowing date is the state of the structure 100A in FIG. 17 . On the day 30 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 30 days after the sowing date is associated with the fact that the ceiling 150 will move 30 cm in the Y direction. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction. The state of the structure 100A in FIG. 17 becomes the state of the structure 100A in FIG. 18 due to the operation of the ceiling 150. The height of the ceiling 150 in FIG. 18 is 30 cm higher than the height of the ceiling 150 in FIG. 17 .

[0081] The state of the structure 100A on the day 45 days after the sowing date is the state of the structure 100A in FIG. 19 . On the day 45 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 45 days after the sowing date is associated with the fact that the ceiling 150 will move 30 cm in the Y direction. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction. The state of the structure 100A in FIG. 19 becomes the state of the structure 100A in FIG. 20 due to the operation of the ceiling 150. The height of the ceiling 150 in FIG. 20 is 30 cm higher than the height of the ceiling 150 in FIG. 19 .

[0082] The state of the structure 100A on the day 60 days after the sowing date is the state of the structure 100A in FIG. 21 . On the day 60 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 60 days after the sowing date is associated with the fact that the ceiling 150 will not operate. Therefore, the structure control unit 162 does not operate the ceiling 150. In other words, the structure control unit 162 controls the structure 100A so that it does not operate.

[0083] The structure control unit 162 controls the structure 100A to realize the state of the structure 100A when agricultural work is being performed. For example, before the agricultural work begins, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to set the height of the ceiling 150 to 150 cm and the height of the lowest part (the lowest part) of the first front movable wall 111 to 80 cm. In this way, the structure control unit 162 realizes the state of the structure 100A shown in FIG. 6 . Furthermore, after the agricultural work is completed, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the negative Y direction to realize the state of the structure 100A before the agricultural work.

[0084] (2-2-3) Air Conditioning Control Unit The air conditioning control unit 163 controls the air conditioner 11 so that the interiors I1 and I2 and the space I3 have different temperatures or different humidities. For example, the air conditioning control unit 163 controls the air conditioner 11 so that air heated by the air conditioner 11 is supplied to the interiors I1 and I2. As a result, the temperatures of the interiors I1 and I2 become higher than the temperature of the space I3. For example, the air conditioning control unit 163 controls the air conditioner 11 so that air humidified by the air conditioner 11 is supplied to the interiors I1 and I2. As a result, the humidity of the interiors I1 and I2 becomes higher than the humidity of the space I3. Note that the air conditioning control unit 163 may also control the air conditioner 11 so that the interiors I1 and I2 have different temperatures or different humidities.

[0085] Except when agricultural work is being performed (when the structure 100A is in the form shown in FIG. 6 ), the interior I1 is not in communication with the space I3 (except for gaps between the components of the structure 100A). Air conditioned by the air conditioning control unit 163 does not easily flow from the interior I1 to the space I3. As a result, the interior I1 and the space I3 have different temperatures or humidities.

[0086] (3) Operation The operation of the structure system 1 from the sowing date to the harvest date (the day the plants P are harvested) will be described. Since the structure 100B operates in the same manner as the structure 100A, the operation of the structure 100A will be mainly described. It is assumed that the space information of FIG. 13 received by the receiving unit 1613 is pre-recorded in the memory unit 1615.

[0087] It is assumed that the plant P grows approximately 2 cm per day until the growth end date. The structure control cycle is 15 days. It is assumed that the growth end date is 60 days after the sowing date. In other words, the change in height of the plant P per day from the sowing date to the day 60 days after the sowing date is 2 cm. After the day 60 days after the sowing date, the change in height of the plant P per day is 0 cm. It is assumed that the growth end date is the harvest date. It is assumed that the air conditioning control unit 163 controls the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I1 is suitable for growing the plant P.

[0088] Figure 22 is a flowchart showing the operation of the structure system 1. On the sowing day, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to realize the structure 100A shown in Figure 6 (step S1). A person or a device moves from outside the greenhouse 10 to near the structure 100A via the entrance / exit 101 and the passage 102. The interior I1 is connected to the passage 102. The person or device performs the sowing work of the plants P in the interior I1.

[0089] On the sowing day, after completing the sowing work, the person or device moves outside the greenhouse 10 via the passage 102 and the entrance / exit 101. The structure control unit 162 operates the ceiling 150 and the first front movable wall 111 in the negative Y direction to realize the structure 100A shown in FIG. 15 (step S2). Since the seeds have just been sowed, the plants P have not yet germinated. The height of the ceiling 150 is 60 cm.

[0090] On the sowing date, the motion identification unit 1614 reads the spatial information stored in the storage unit 1615. The motion identification unit 1614 identifies the required space N in FIG. 8 associated with the sowing date. The motion identification unit 1614 identifies motion information by associating the sowing date with the fact that the ceiling 150 does not move (step S3). The motion identification unit 1614 records the identified motion information in the storage unit 1615.

[0091] On the sowing day, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S4). The height of the ceiling 150 remains at 60 cm.

[0092] 15 days after the sowing date, the height of the plants P is approximately 30 cm. Therefore, the structure 100A and the plants P are in the form of the structure 100A and the plants P shown in FIG.

[0093] On the day 15 days after the sowing date, the motion identification unit 1614 reads the space information stored in the storage unit 1615. The motion identification unit 1614 identifies the required space N in FIG. 9 associated with the day 15 days after the sowing date. The motion identification unit 1614 identifies motion information by associating the day 15 days after the sowing date with the fact that the ceiling 150 does not operate (step S5). The motion identification unit 1614 records the identified motion information in the storage unit 1615.

[0094] On the 15th day after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S6). The height of the ceiling 150 remains at 60 cm.

[0095] Thirty days after the sowing date, the height of the plant P is approximately 60 cm. Therefore, the structure 100A and the plant P have the same configuration as that of the structure 100A and the plant P shown in FIG.

[0096] On the day 30 days after the sowing date, the operation identification unit 1614 reads the spatial information stored in the storage unit 1615. The operation identification unit 1614 identifies the required space N in Fig. 10 associated with the day 30 days after the sowing date. The operation identification unit 1614 identifies operation information by associating the day 30 days after the sowing date with the fact that the ceiling 150 moves 30 cm in the Y direction (step S7).

[0097] On the day 30 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction (step S8). The structure 100A in FIG. 17 becomes the structure 100A in FIG. 18 due to the movement of the ceiling 150. The height of the ceiling 150 changes from 60 cm to 90 cm. The volume of the interior I1 increases.

[0098] After 45 days from the date of sowing, the height of the plant P is approximately 90 cm. Therefore, the structure 100A and the plant P are in the form of the structure 100A and the plant P shown in FIG.

[0099] On the day 45 days after the sowing date, the motion identification unit 1614 reads the spatial information stored in the storage unit 1615. The motion identification unit 1614 identifies the required space N in FIG. 11 associated with the day 45 days after the sowing date. The motion identification unit 1614 identifies motion information by associating the day 45 days after the sowing date with the fact that the ceiling 150 moves 30 cm in the Y direction (step S9).

[0100] On the day 45 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction (step S10). The structure 100A in FIG. 19 changes to the structure 100A in FIG. 20 due to the movement of the ceiling 150. The height of the ceiling 150 changes from 90 cm to 120 cm. The volume of the interior I1 increases.

[0101] After 60 days have passed since the sowing date, the height of the plant P will be approximately 120 cm. Therefore, the structure 100A and the plant P will be in the form of the structure 100A and the plant P shown in FIG.

[0102] On the day 60 days after the sowing date (growth end date, harvest date), the operation identification unit 1614 identifies that there is no required space N associated with the day 60 days after the sowing date. The operation identification unit 1614 identifies operation information by associating the day 60 days after the sowing date with the fact that the ceiling 150 will not operate (step S11).

[0103] On the day 60 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S12). The height of the ceiling 150 remains at 120 cm.

[0104] On the day 60 days after the sowing date, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to realize the structure 100A shown in FIG. 6 (step S13). A person or a device moves from outside the greenhouse 10 to near the structure 100A through the entrance / exit 101 and the passage 102. The interior I1 is connected to the passage 102. The person or device harvests the plants P in the interior I1.

[0105] On the day 60 days after the sowing date, after the harvesting work is completed, the person or device moves to the outside of the greenhouse 10 via the passage 102 and the entrance / exit 101. The structure control unit 162 operates the ceiling 150 and the first front movable wall 111 in the negative Y direction to realize the structure 100A shown in FIG. 15 (step S14). Since it is immediately after the harvest, there are no plants P inside I1.

[0106] Note that agricultural work may be performed in the structure 100A from step S3 to step S12. In this case, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction before the agricultural work starts, thereby realizing the state of the structure 100A shown in FIG. 6. Furthermore, after the agricultural work is completed, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the negative Y direction, thereby realizing the state of the structure 100A before the agricultural work starts.

[0107] (4) Features (4-1) The information processing device 161 includes an action identification unit 1614. The action identification unit 1614 identifies action information indicating actions of the structures 100A and 100B that secure the required space N. The structures 100A and 100B have plants P cultivated in their interiors I1 and I2. The structures 100A and 100B are variable structures that can change the volumes of the interiors I1 and I2 depending on the action. The required space N is the space required for the growth of the plants P in the structures 100A and 100B.

[0108] When plants are grown inside a structure, the interior of the structure is air-conditioned to create an environment suitable for plant cultivation. The amount of energy required for air-conditioning correlates with the volume of the structure's interior. As plants grow, the space they require increases. When cultivating plants in a non-variable structure whose interior volume cannot be changed, space must be secured based on the maximum space required (maximum plant volume) once the plants have finished growing. In a non-variable structure, air conditioning must be performed according to the maximum space required by the plants. Therefore, unnecessary space is air-conditioned while the plants are growing. This increases the amount of energy required to cultivate plants inside the structure, leading to increased costs for plant cultivation.

[0109] The information processing device 161 identifies operation information indicating the operation of the structures 100A and 100B that secure the required space N. Therefore, the information processing device 161 can achieve energy conservation for cultivating the plants P in the interiors I1 and I2, and can reduce the cost for cultivating the plants P.

[0110] (4-2) The information processing device 161 further includes a receiving unit 1613 that receives spatial information indicating the required space N. The motion identifying unit 1614 identifies motion information based on the spatial information.

[0111] Therefore, the information processing device 161 can achieve energy savings in cultivating the plants P in the interiors I1 and I2, and can reduce the costs associated with cultivating the plants P.

[0112] (4-3) The control device 16 controls the structures 100A and 100B so that the required space N is secured by the structure control unit 162 raising the ceilings 150 of the structures 100A and 100B.

[0113] As the plants grow, they become taller. The control device 16 secures the required space N by raising the ceiling 150. Therefore, the control device 16 can achieve energy savings in cultivating the plants P, and can reduce the costs associated with cultivating the plants P.

[0114] (4-4) The control device 16 is configured such that the variable structure 100A and the structure 100B are provided inside another non-variable structure whose internal volume cannot be changed by operation.

[0115] Because variable structures are structures that can change their form, they may be vulnerable to physical external forces. Therefore, variable structures may be damaged by external forces such as strong winds, typhoons, and accumulated snow. Variable structures 100A and 100B are installed inside non-variable structures. Therefore, the control device 16 can control structures 100A and 100B, which are more resistant to external forces. Furthermore, interiors I1 and I2 are doubly insulated from the outside. Therefore, structures 100A and 100B controlled by the control device 16 can achieve energy savings in cultivating plants P and reduce costs associated with cultivating plants P.

[0116] (4-5) The control device 16 further includes an air conditioning control unit 163 that controls the air conditioner 11 that conditions the air in the interior I1 of the variable structure 100A and the interior I2 of the structure 100B. The air conditioning control unit 163 controls the air conditioner 11 so that the interior I1 of the variable structure 100A and the interior I2 of the structure 100B are at different temperatures or humidity from the interiors of the non-variable structures that are outside the variable structures 100A and 100B.

[0117] Plants P are cultivated in the interiors I1 and I2, but not in the space I3. Therefore, the environments required for the interiors I1 and I2 are different from the environments required for the space I3. The control device 16 controls the interiors I1 and I2 to have different temperatures or humidities from the space I3. Therefore, the control device 16 can save energy required for cultivating the plants P and reduce the costs required for cultivating the plants P.

[0118] (4-6) The control device 16 includes a structure control unit 162 that controls the structures 100A and 100B to secure the required space N through their movements based on the movement information identified by the movement identification unit 1614 of the information processing device 161.

[0119] Therefore, the control device 16 can achieve energy savings in cultivating the plants P in the interiors I1 and I2, and can reduce the costs associated with cultivating the plants P.

[0120] (5) Modifications The following description of modifications of the first embodiment will focus on the differences from the first embodiment, omitting the description of the similarities to the first embodiment.

[0121] (5-1) Modification 1A (5-1-1) Configuration The information processing device 161 does not have to have the action identification unit 1614. Fig. 23 is a functional block diagram of the control device 16 according to Modification 1A.

[0122] The receiving unit 1613 does not receive spatial information. The receiving unit 1613 receives motion information from an external device (not shown) or a user. Alternatively, the receiving unit 1613 may receive motion information from an external device via a network using real-time processing or badge processing.

[0123] For example, the receiving unit 1613 receives the motion information of Fig. 14 from the user. The receiving unit 1613 records the received motion information in the storage unit 1615. The storage unit 1615 stores the motion information.

[0124] (5-1-2) Operation The operation of the structure system 1 according to Modification 1A will be described. Since the structure 100B operates in the same manner as the structure 100A, the operation of the structure 100A will be mainly described. It is assumed that the operation information of FIG. 14 received by the receiving unit 1613 is pre-recorded in the storage unit 1615.

[0125] It is assumed that the plant P grows approximately 2 cm taller per day until the growth end date. The structure control cycle is 15 days. The growth end date is 60 days. In other words, from the sowing date until 60 days after the sowing date, the daily change in height of the plant P is 2 cm. After 60 days have passed since the sowing date, the daily change in height of the plant P is 0 cm. It is assumed that the growth end date is the harvest date. It is assumed that the air conditioning control unit 163 controls the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I1 becomes an environment suitable for growing the plant P.

[0126] 24 is a flowchart showing the operation of the structure system 1 according to Modification 1A. On the sowing day, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to realize the structure 100A shown in FIG. 6 (step S21). A person or a device sows plants P in the interior I1.

[0127] On the sowing day, after the sowing work is completed, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the negative Y direction to realize the structure 100A shown in Fig. 15 (step S22). The height of the ceiling 150 is 60 cm.

[0128] On the sowing day, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S23). The height of the ceiling 150 remains at 60 cm.

[0129] After 15 days from the date of sowing, the height of the plants P reaches approximately 30 cm. Therefore, the structure 100A and the plants P are in the form of the structure 100A and the plants P shown in FIG.

[0130] On the 15th day after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S24). The height of the ceiling 150 remains at 60 cm.

[0131] Thirty days after the sowing date, the height of the plants P is approximately 60 cm. Therefore, the structure 100A and the plants P are in the form of the structure 100A and the plants P shown in FIG.

[0132] On the day 30 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction (step S25). The structure 100A in FIG. 17 changes to the structure 100A in FIG. 18 due to the movement of the ceiling 150. The height of the ceiling 150 changes from 60 cm to 90 cm. The volume of the interior I1 increases.

[0133] After 45 days from the date of sowing, the height of the plant P is approximately 90 cm. Therefore, the structure 100A and the plant P are in the form of the structure 100A and the plant P shown in FIG.

[0134] On the day 45 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction (step S26). The structure 100A in FIG. 19 changes to the structure 100A in FIG. 20 due to the movement of the ceiling 150. The height of the ceiling 150 changes from 90 cm to 120 cm. The volume of the interior I1 increases.

[0135] After 60 days from the date of sowing, the height of the plant P is approximately 120 cm. Therefore, the structure 100A and the plant P are in the form of the structure 100A and the plant P shown in FIG.

[0136] On the day 60 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 controls the structure 100A so that the structure 100A does not operate (step S27). The height of the ceiling 150 remains at 120 cm.

[0137] On the day 60 days after the sowing date, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to realize the structure 100A shown in Figure 6 (step S28). A person or a device harvests the plants P in the interior I1.

[0138] After the harvesting work is completed, the structure control unit 162 operates the ceiling 150 and the first front movable wall 111 in the negative Y direction to realize the state of the structure 100A in FIG. 15 (step S29).

[0139] (5-2) Modification 1B (5-2-1) Configuration The structure 100A and the structure 100B may be provided inside a plant factory 20 instead of inside the greenhouse 10. The plant factory 20 refers to a building in which plants P are cultivated. FIG. 25 is a schematic diagram showing the overall configuration of the structure system 1 according to modification 1B. In modification 1B, height is the distance in the Y direction from the ground F, except in cases where it is described as a relative height.

[0140] A rack R1 is provided in the interior I1 of the structure 100A. A rack R2 is provided in the interior I2 of the structure 100B. The structures of the rack R1 and the rack R2 are roughly symmetrical with respect to a plane extending in the Y direction and the Z direction. The functions of the rack R1 and the rack R2 are similar. Rack R1 will be described in detail below.

[0141] 26 and 27 are diagrams showing the detailed configuration of the rack R1. The rack R1 mainly has a fixed base 181, a movable base 182, a movable base 183, a fifth guide rail 184A, a sixth guide rail 184B, a seventh guide rail 184C, and an eighth guide rail 184D. The rack R1 may also have a lighting device (not shown) that serves as a light source for the plants P.

[0142] The fixed base 181, the movable base 182, and the movable base 183 are parallel to one another. The fixed base 181, the movable base 182, and the movable base 183 are provided in three stages in the upward direction (Y direction). The fixed base 181 is fixed to the ground F.

[0143] The fifth guide rail 184A, the sixth guide rail 184B, the seventh guide rail 184C, and the eighth guide rail 184D are provided in a direction (Y direction) that is generally perpendicular to the ground F. The fifth guide rail 184A, the sixth guide rail 184B, the seventh guide rail 184C, and the eighth guide rail 184D are provided so as to penetrate the ceiling 150 in the Y direction through holes (not shown) in the ceiling 150.

[0144] Soil (not shown) or nutrient solution (not shown) is present on the fixed base 181, the movable base 182, and the movable base 183. The plant P is planted in the soil or immersed in the nutrient solution on the fixed base 181, the movable base 182, and the movable base 183.

[0145] The movable bases 182 and 183 are guided by the fifth guide rail 184A, the sixth guide rail 184B, the seventh guide rail 184C, and the eighth guide rail 184D, and are configured so as to be able to slide in the Y direction or the negative Y direction (the direction in which the fifth guide rail 184A, the sixth guide rail 184B, the seventh guide rail 184C, and the eighth guide rail 184D extend).

[0146] For example, when the movable base 182 and the movable base 183 slide in the Y direction, the rack R1 can change from the state of the rack R1 in Fig. 26 to the state of the rack R1 in Fig. 27. For example, when the movable base 182 and the movable base 183 slide in the negative Y direction, the rack R1 can change from the state of the rack R1 in Fig. 27 to the state of the rack R1 in Fig. 26.

[0147] Because the movable bases 182 and 183 are movable components, the rack R1 can be said to be a structure whose configuration can be changed. The method by which the rack R1 changes its configuration is not limited to the above example. The configuration of the rack R1 may be changed by any method conceivable by a person skilled in the art. The rack R1 does not need to have the fixed base 181. The rack R1 does not need to have the fifth guide rail 184A and the sixth guide rail 184B. In this case, the movable bases 182 and 183 are guided by the seventh guide rail 184C and the eighth guide rail 184D and are arranged so as to be able to slide in the Y direction or the negative Y direction.

[0148] (5-2-1-2) Required Space An example of the required space N will be described. The depth value (length in the X direction) of the required space N is the same as the depth value of rack R1. The width value (length in the Z direction) of the required space N is the same as the width value of rack R1. The bottom surface of the required space N (a surface extending in the X and Z directions and located below (in the minus Y direction)) is parallel to the ground F. The top surface of the required space N (a surface extending in the X and Z directions and located above (in the Y direction)) is parallel to the ground F.

[0149] Since a plant P exists on each table (fixed table 181, movable table 182, movable table 183), the required space N also exists on each table (fixed table 181, movable table 182, movable table 183). The height of the bottom surface of the required space N and the height of the top surface of the required space N are heights relative to each table. The height of the plant P is also a height relative to each table. The height relative to the fixed table 181 is the distance in the Y direction from the fixed table 181. The height relative to the movable table 182 is the distance in the Y direction from the movable table 182. The height relative to the movable table 183 is the distance in the Y direction from the movable table 183.

[0150] The height of the bottom surface of the required space N (height relative to each plant) is the same as the height of the plant P (height relative to each plant) at the current time (the time when the required space N is identified). The height of the top surface of the required space N (height relative to each plant) is the same as the height of the plant P one structure control cycle from the current time (height relative to each plant). The height of the plant P one structure control cycle after the current time (height relative to each plant) is the sum of the height of the plant P at the current time (height relative to each plant) and the change in the height of the plant P over one structure control cycle.

[0151] For example, let's say that the plant P grows approximately 1 cm taller per day until the growth end date. The structure control cycle is 15 days. The growth end date is 30 days. In other words, from the sowing date until 30 days after the sowing date, the daily change in height of the plant P is 1 cm. After 30 days have passed since the sowing date, the daily change in height of the plant P is 0 cm. Based on the above assumptions, a specific example of the required space N will be described.

[0152] 28, 29, and 30 are diagrams showing examples of the required space N, etc. The state of rack R1 in FIG. 28 is assumed to be the state on the sowing day. The height of fixed base 181 (distance in the Y direction from the ground F) is 0 cm, the height of movable base 182 (height relative to fixed base 181) is 15 cm, and the height of movable base 183 (height relative to movable base 182) is 15 cm. In other words, the height of movable base 182 (distance in the Y direction from the ground F) is 15 cm, and the height of movable base 183 (distance in the Y direction from the ground F) is 30 cm.

[0153] Because the plant P has not germinated, the height of the plant P (height relative to each plant) is approximately 0 cm. Because the plant P has not germinated, the plant P is not shown in FIG. 28. Therefore, the height of the bottom surface of the required space N (height relative to each plant) is 0 cm, which is the height of the plant P at the current time (height relative to each plant). The height of the top surface of the required space N (height relative to each plant) is 15 cm, which is the sum of 0 cm, which is the height of the plant P at the current time (height relative to each plant), and 15 cm, which is the change in the height of the plant P from the current time in one structure control cycle.

[0154] 29 is assumed to be the state of the rack R1 and the plants P 15 days after sowing. The height of the fixed table 181 (distance from the ground F in the Y direction) is 0 cm, the height of the movable table 182 (height relative to the fixed table 181) is 15 cm, and the height of the movable table 183 (height relative to the movable table 182) is 15 cm. In other words, the height of the movable table 182 (distance from the ground F in the Y direction) is 15 cm, and the height of the movable table 183 (distance from the ground F in the Y direction) is 30 cm.

[0155] The height of the plant P (height relative to each plant) is approximately 15 cm. Therefore, the height of the bottom surface of the required space N (height relative to each plant) is 15 cm, which is the height of the plant P at the current time (height relative to each plant). The height of the top surface of the required space N (height relative to each plant) is 30 cm, which is the sum of 15 cm, which is the height of the plant P at the current time (height relative to each plant), and 15 cm, which is the change in the height of the plant P during one cycle of the structure control period.

[0156] Fig. 30 is a schematic diagram showing the plants P on each stand in Fig. 29 and the required space N for each stand. Each stand has a plant P with a height of 15 cm (height relative to each stand), and there is a required space N above the plant P.

[0157] Figure 31 is a diagram showing an example of the state of the rack R1. The state of the rack R1 and the plant P in Figure 31 is assumed to be the state 30 days after the sowing date. The height of the fixed table 181 (distance in the Y direction from the ground F) is 0 cm, the height of the movable table 182 (height relative to the fixed table 181) is 30 cm, and the height of the movable table 183 (height relative to the movable table 182) is 30 cm. In other words, the height of the movable table 182 (distance in the Y direction from the ground F) is 30 cm, and the height of the movable table 183 (distance in the Y direction from the ground F) is 60 cm.

[0158] The height of the plant P (height relative to each plant) is approximately 30 cm. The plant P has finished growing. Therefore, the height of the bottom surface of the required space N (height relative to each plant) is 30 cm, which is the height of the plant P at the current time (height relative to each plant). The height of the top surface of the required space N (height relative to each plant) is 30 cm, which is the sum of the current height of the plant P (height relative to each plant) of 30 cm and 0 cm, which is the change in height of the plant P in one cycle of the structure control period. The required space N is a space with a height from the bottom to the top surface of 0 cm. In other words, the required space N does not exist.

[0159] (5-2-1-3) Spatial Information FIG. 32 is a diagram showing an example of spatial information.

[0160] (5-2-1-4) Operation Identification Unit The operation information is information indicating the operation of the structures 100A and 100B to secure the required space N, and the operation of the racks R1 and R2 to secure the required space N. During these operations, the isolation of the interiors I1 and I2 from the outside (space I3) of the structures 100A and 100B is maintained. For example, the operation information is information that associates the date, the operation of the movable base 182, the operation of the movable base 183, and the operation of the ceiling 150.

[0161] An example of the processing of the action identification unit 1614 will be described below. The action identification unit 1614 reads the spatial information stored in the storage unit 1615. The action identification unit 1614 identifies a date similar to the current date from among the dates included in the spatial information. The action identification unit 1614 identifies the required space N associated with the identified date. The action identification unit 1614 compares the three-dimensional coordinates of the identified required space N with the three-dimensional coordinates of the structure 100A and the rack R1.

[0162] The movement identification unit 1614 identifies the movements of the structure 100A and the rack R1 that secure the required space N (the movements of the movable base 182, the movable base 183, and the ceiling 150). The movement identification unit 1614 identifies the movements of the components that are located below (in the negative Y direction) among the movable components (the movable base 182, the movable base 183, and the ceiling 150). The movement identification unit 1614 identifies the next movement on the assumption that the previously identified movement has been performed.

[0163] First, the motion identification unit 1614 identifies the motion of the movable platform 182, which is located at the bottom among the movable platform 182, the movable platform 183, and the ceiling 150. The motion identification unit 1614 identifies the motion of the movable platform 182 so that the height of the movable platform 182 (height relative to the fixed platform 181) is higher than the height of the upper surface of the required space N of the fixed platform 181 (height relative to the fixed platform 181).

[0164] Next, the action identification unit 1614 identifies the action of the movable platform 183, which is the second lowest among the movable platform 182, the movable platform 183, and the ceiling 150. The action identification unit 1614 identifies the action of the movable platform 183 on the premise that the previously identified action of the movable platform 182 has been performed. The action identification unit 1614 identifies the action of the movable platform 183 so that the height of the movable platform 183 (height relative to the movable platform 182) is higher than the height of the upper surface of the required space N of the movable platform 182 (height relative to the movable platform 182).

[0165] Finally, the motion identification unit 1614 identifies the motion of the ceiling 150, which is the third lowest among the movable platform 182, the movable platform 183, and the ceiling 150. The motion identification unit 1614 identifies the motion of the ceiling 150 on the premise that the previously identified motions of the movable platform 182 and the movable platform 183 have been performed. The motion identification unit 1614 identifies the motion of the ceiling 150 so that the height of the ceiling 150 (the height relative to the movable platform 183) is higher than the height of the upper surface of the required space N of the movable platform 183 (the height relative to the movable platform 183).

[0166] The operation identification unit 1614 associates the identified operations of the structure 100A and the rack R1 with the current date to identify operation information. The operation identification unit 1614 records the identified operation information in the storage unit 1615.

[0167] Below, a specific example of the processing of the action identification unit 1614 when the spatial information is the spatial information of Fig. 32 will be described. Fig. 34, Fig. 35, Fig. 36, and Fig. 37 are diagrams showing examples of aspects of the structure 100A and the rack R1.

[0168] 34 is a diagram showing an example of the structure 100A and rack R1 on the sowing day. Assume that the height of the fixed platform 181 (distance from the ground F in the Y direction) is 0 cm, the height of the movable platform 182 (height relative to the fixed platform 181) is 15 cm, the height of the movable platform 183 (height relative to the movable platform 182) is 15 cm, and the height of the ceiling 150 (height relative to the movable platform 183) is 30 cm. In other words, the height of the movable platform 182 (distance from the ground F in the Y direction) is 15 cm, the height of the movable platform 183 (distance from the ground F in the Y direction) is 30 cm, and the height of the ceiling 150 (distance from the ground F in the Y direction) is 60 cm.

[0169] On the sowing day, the operation identification unit 1614 identifies the required space N in Fig. 28 associated with the sowing day. The operation identification unit 1614 compares the three-dimensional coordinates of the required space N in Fig. 28 with the three-dimensional coordinates of the structure 100A and the rack R1.

[0170] The height of movable base 182 (height relative to fixed base 181, 15 cm) is the same as the height of the upper surface of required space N of fixed base 181 (height relative to fixed base 181, 15 cm). The height of movable base 183 (height relative to movable base 182, 15 cm) is the same as the height of the upper surface of required space N of movable base 182 (height relative to movable base 182, 15 cm). The height of ceiling 150 (height relative to movable base 183, 30 cm) is higher than the height of the upper surface of required space N of movable base 183 (height relative to movable base 183, 15 cm).

[0171] On the sowing date, the action identification unit 1614 identifies that the required space N has been secured in the interior I1. The action identification unit 1614 identifies action information by associating the sowing date with the fact that the movable base 182 does not move, the fact that the movable base 183 does not move, and the fact that the ceiling 150 does not move. The action identification unit 1614 records the identified action information in the storage unit 1615.

[0172] 35 is a diagram showing an example of the structure 100A and rack R1 15 days after sowing. The height of the fixed platform 181 (distance from the ground F in the Y direction) is 0 cm, the height of the movable platform 182 (height relative to the fixed platform 181) is 15 cm, the height of the movable platform 183 (height relative to the movable platform 182) is 15 cm, and the height of the ceiling 150 (height relative to the movable platform 183) is 30 cm. In other words, the height of the movable platform 182 (distance from the ground F in the Y direction) is 15 cm, the height of the movable platform 183 (distance from the ground F in the Y direction) is 30 cm, and the height of the ceiling 150 (distance from the ground F in the Y direction) is 60 cm.

[0173] On the day 15 days after the sowing date, the operation identification unit 1614 identifies the required space N in Fig. 29 that is associated with the day 15 days after the sowing date. The operation identification unit 1614 compares the three-dimensional coordinates of the required space N in Fig. 29 with the three-dimensional coordinates of the structure 100A and the rack R1.

[0174] The height of the movable base 182 (15 cm relative to the fixed base 181) is 15 cm lower than the height of the upper surface of the required space N of the fixed base 181 (30 cm relative to the fixed base 181). The movement specification unit 1614 specifies that the movable base 182 moves 15 cm in the Y direction.

[0175] Assuming that the movable platform 182 moves 15 cm in the Y direction, the height of the movable platform 183 (height relative to the movable platform 182, 0 cm) is 30 cm lower than the height of the upper surface of the required space N of the movable platform 182 (height relative to the movable platform 182, 30 cm). The operation identification unit 1614 identifies that the movable platform 183 moves 30 cm in the Y direction.

[0176] Assuming that the movable platform 182 moves 15 cm in the Y direction and the movable platform 183 moves 30 cm in the Y direction, the height of the ceiling 150 (height relative to the movable platform 183, 0 cm) is 30 cm lower than the height of the top surface of the required space N of the movable platform 183 (height relative to the movable platform 183, 30 cm). The movement specification unit 1614 specifies that the ceiling 150 moves 30 cm in the Y direction.

[0177] The operation identification unit 1614 identifies operation information by associating the date 15 days after the sowing date with the fact that the movable table 182 will move 15 cm in the Y direction, the fact that the movable table 183 will move 30 cm in the Y direction, and the fact that the ceiling 150 will move 30 cm in the Y direction. The operation identification unit 1614 records the identified operation information in the storage unit 1615.

[0178] 37 is a diagram showing an example of the structure 100A and rack R1 30 days after the sowing date. Assume that the height of the fixed platform 181 (distance from the ground F in the Y direction) is 0 cm, the height of the movable platform 182 (height relative to the fixed platform 181) is 30 cm, the height of the movable platform 183 (height relative to the movable platform 182) is 30 cm, and the height of the ceiling 150 (height relative to the movable platform 183) is 30 cm. In other words, the height of the movable platform 182 (distance from the ground F in the Y direction) is 30 cm, the height of the movable platform 183 (distance from the ground F in the Y direction) is 60 cm, and the height of the ceiling 150 (distance from the ground F in the Y direction) is 90 cm.

[0179] On the day 30 days after the sowing date, the operation identification unit 1614 identifies that there is no required space N associated with the day 30 days after the sowing date. The operation identification unit 1614 identifies operation information by associating the day 30 days after the sowing date with the fact that the movable base 182 does not operate, the fact that the movable base 183 does not operate, and the fact that the ceiling 150 does not operate. The operation identification unit 1614 records the identified operation information in the storage unit 1615.

[0180] 33 is a diagram showing an example of the motion information. The motion identification unit 1614 identifies the motion information in FIG. 33 through the above processing.

[0181] (5-2-1-5) Structure Control Unit An example of the processing of the structure control unit 162 will now be described. The structure control unit 162 reads the operation information stored in the storage unit 1615. The structure control unit 162 identifies a date similar to the current date from among the dates included in the operation information. The structure control unit 162 identifies the operations of the structure 100A and rack R1 associated with the identified date (the operation of the movable base 182, the operation of the movable base 183, and the operation of the ceiling 150). The structure control unit 162 controls the structure 100A and rack R1 based on the identified operations of the structure 100A and rack R1. The structure control unit 162 controls the movable components of the structure 100A and rack R1, starting with the components located above (in the Y direction).

[0182] Below, a specific example of processing by the structure control unit 162 when the operation information is the operation information of FIG. 33 will be described. The state of the structure 100A and the rack R1 on the sowing date is the state of the structure 100A and the rack R1 of FIG. 34. On the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The operation information associates the sowing date with the fact that the movable table 182 will not operate, the fact that the movable table 183 will not operate, and the fact that the ceiling 150 will not operate. Therefore, the structure control unit 162 does not operate the movable table 182, the movable table 183, and the ceiling 150. In other words, the structure control unit 162 controls the structure 100A and the rack R1 so that the structure 100A and the rack R1 will not operate.

[0183] The state of the structure 100A and the rack R1 on the day 15 days after the sowing date is the state of the structure 100A and the rack R1 in Fig. 35. On the day 15 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 15 days after the sowing date is associated with the movement of the movable table 182 by 15 cm in the Y direction, the movement of the movable table 183 by 30 cm in the Y direction, and the movement of the ceiling 150 by 30 cm in the Y direction.

[0184] The structure control unit 162 controls the movable table 182, the movable table 183, and the ceiling 150, starting with the ceiling 150, which is the uppermost one. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction. Next, the structure control unit 162 controls the movable table 183, which is the second-highest one among the movable table 182, the movable table 183, and the ceiling 150. The structure control unit 162 moves the movable table 183 30 cm in the Y direction. Finally, the structure control unit 162 controls the movable table 182, which is the third-highest one among the movable table 182, the movable table 183, and the ceiling 150. The structure control unit 162 moves the movable table 182 15 cm in the Y direction.

[0185] The state of the structure 100A and rack R1 in FIG. 35 becomes the state of the structure 100A and rack R1 in FIG. 36 by the operation of the movable base 182, the movable base 183, and the ceiling 150.

[0186] The state of the structure 100A and the rack R1 on the day 30 days after the sowing date is the state of the structure 100A and the rack R1 in FIG. 37 . On the day 30 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. In the operation information, the day 30 days after the sowing date is associated with the fact that the movable base 182 will not operate, the fact that the movable base 183 will not operate, and the fact that the ceiling 150 will not operate. Therefore, the structure control unit 162 does not operate the movable base 182, the movable base 183, and the ceiling 150. In other words, the structure control unit 162 controls the structure 100A and the rack R1 so that they do not operate.

[0187] FIG. 38 is a diagram illustrating an example of the configuration of the structure 100A and rack R1 when agricultural work is being performed. Before the agricultural work begins, the structure control unit 162 moves the ceiling 150 and the first front movable wall 111 in the Y direction to set the height of the ceiling 150 to 150 cm and the height of the lowest part (lowest part) of the first front movable wall 111 to 85 cm. Furthermore, before the agricultural work begins, the structure control unit 162 also moves the movable base 182 and the movable base 183 in the Y direction to set the height of the movable base 182 (distance from the ground F in the Y direction) to 30 cm and the height of the movable base 183 (distance from the ground F in the Y direction) to 60 cm. In this way, the structure control unit 162 realizes the configuration of the structure 100A and rack R1 shown in FIG. 38 . In addition, after the agricultural work is completed, the structure control unit 162 operates the movable table 182 and the movable table 183 in the negative Y direction in addition to the first front movable wall 111 and the ceiling 150 in order to realize the state of the structure 100A and the rack R1 before the agricultural work.

[0188] (5-2-2) Operation The operation of the structure system 1 according to variant 1B from the sowing date to the harvest date will be described. Since structure 100B operates in the same manner as structure 100A, the operation of structure 100A will be mainly described. Since rack R2 operates in the same manner as rack R1, the operation of rack R1 will be mainly described. It is assumed that the spatial information of FIG. 32 received by the receiving unit 1613 is pre-recorded in the memory unit 1615.

[0189] It is assumed that the plant P grows approximately 1 cm taller per day until the growth end date. The structure control cycle is 15 days. The growth end date is 30 days. In other words, from the sowing date until 30 days after the sowing date, the daily change in height of the plant P is 1 cm. After 30 days have passed since the sowing date, the daily change in height of the plant P is 0 cm. It is assumed that the harvest date is 40 days after the sowing date. It is assumed that the air conditioning control unit 163 controls the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I1 is suitable for growing the plant P.

[0190] Figure 39 is a flowchart showing the operation of the structure system 1. On the sowing day, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable base 182, and the movable base 183 in the Y direction to realize the configuration of the structure 100A and rack R1 in Figure 38 (step S31). A person or a device performs the work of sowing plants P in the interior I1.

[0191] On the sowing day, after the sowing work is completed, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable table 182, and the movable table 183 in the negative Y direction to realize the structure 100A and rack R1 shown in Figure 34 (step S32).

[0192] The height of the fixed base 181 (distance from the ground F in the Y direction) is 0 cm, the height of the movable base 182 (height relative to the fixed base 181) is 15 cm, the height of the movable base 183 (height relative to the movable base 182) is 15 cm, and the height of the ceiling 150 (height relative to the movable base 183) is 30 cm. In other words, the height of the movable base 182 (distance from the ground F in the Y direction) is 15 cm, the height of the movable base 183 (distance from the ground F in the Y direction) is 30 cm, and the height of the ceiling 150 (distance from the ground F in the Y direction) is 60 cm.

[0193] On the sowing date, the motion identification unit 1614 reads the spatial information stored in the storage unit 1615. The motion identification unit 1614 identifies the required space N in FIG. 28 associated with the sowing date. The motion identification unit 1614 identifies motion information by associating the sowing date with the fact that the movable base 182 does not move, the fact that the movable base 183 does not move, and the fact that the ceiling 150 does not move (step S33). The motion identification unit 1614 records the identified motion information in the storage unit 1615.

[0194] On the sowing day, the structure control unit 162 reads the operation information stored in the storage unit 1615. The structure control unit 162 controls the structure 100A and the rack R1 so that the structure 100A and the rack R1 do not operate (step S34).

[0195] After 15 days from the date of sowing, the height of the plants P (relative height to each stand) will be approximately 15 cm. Therefore, the relationship between the structure 100A, the rack R1, and the plants P will be the relationship between the structure 100A, the rack R1, and the plants P shown in FIG. 35.

[0196] On the day 15 days after the sowing date, the motion identification unit 1614 reads the spatial information stored in the storage unit 1615. The motion identification unit 1614 identifies the required space N in FIG. 29 associated with the day 15 days after the sowing date. The motion identification unit 1614 identifies motion information by associating the day 15 days after the sowing date with the fact that the movable base 182 moves 15 cm in the Y direction, the fact that the movable base 183 moves 30 cm in the Y direction, and the fact that the ceiling 150 moves 30 cm in the Y direction (step S35). The motion identification unit 1614 records the identified motion information in the storage unit 1615.

[0197] On the day that is 15 days after the sowing date, the structure control unit 162 reads the operation information stored in the memory unit 1615. The structure control unit 162 moves the ceiling 150 30 cm in the Y direction. The structure control unit 162 moves the movable table 183 30 cm in the Y direction. The structure control unit 162 moves the movable table 182 15 cm in the Y direction (step S36).

[0198] The state of the structure 100A and rack R1 in Figure 35 becomes the state of the structure 100A and rack R1 in Figure 36 due to the operation of the movable base 182, the movable base 183, and the ceiling 150. The height of the fixed base 181 (distance in the Y direction from the ground F) is 0 cm. The height of the movable base 182 (height relative to the fixed base 181) is 30 cm. The height of the movable base 183 (height relative to the movable base 182) is 30 cm. The height of the ceiling 150 (height relative to the movable base 183) is 30 cm. In other words, the height of the movable base 182 (distance in the Y direction from the ground F) is 30 cm. The height of the movable base 183 (distance in the Y direction from the ground F) is 60 cm. The height of the ceiling 150 (distance in the Y direction from the ground F) is 90 cm.

[0199] Thirty days after sowing, the height of the plants P (relative to each stand) will be approximately 30 cm. Therefore, the relationship between the structure 100A, the rack R1, and the plants P will be the relationship shown in FIG. 37.

[0200] On the day that has passed 30 days since the sowing date, the operation identification unit 1614 reads the space information stored in the storage unit 1615. The operation identification unit 1614 determines that there is no required space N associated with the day that has passed 30 days since the sowing date. The operation identification unit 1614 identifies operation information by associating the day that has passed 30 days since the sowing date with the fact that the movable base 182 does not operate, the fact that the movable base 183 does not operate, and the fact that the ceiling 150 does not operate (step S37).

[0201] On the day that is 30 days after the sowing date, the structure control unit 162 reads the operation information stored in the storage unit 1615. The structure control unit 162 controls the structure 100A and the rack R1 so that the structure 100A and the rack R1 do not operate (step S38).

[0202] Even though 40 days have passed since the sowing date, the growth end date has passed, so the height of the plants P (relative height to each platform) is approximately 30 cm, which is the same as on the day 30 days after the sowing date.

[0203] On the day (harvest day) that is 40 days after the sowing date, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable base 182, and the movable base 183 in the Y direction to realize the structure 100A and the rack R1 shown in Figure 38 (step S39). A person or a device performs harvesting work of the plants P in the interior I1.

[0204] After the harvesting work is completed, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable table 182, and the movable table 183 in the negative Y direction to realize the structure 100A and rack R1 shown in Figure 34 (step S40).

[0205] Note that agricultural work may be performed on the structure 100A and the rack R1 in steps S33 to S38. In this case, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable base 182, and the movable base 183 in the Y direction before the agricultural work begins, thereby realizing the state of the structure 100A and the rack R1 shown in FIG. 38 . Furthermore, after the agricultural work is completed, the structure control unit 162 moves the first front movable wall 111, the ceiling 150, the movable base 182, and the movable base 183 in the negative Y direction, thereby realizing the state of the structure 100A and the rack R1 before the agricultural work begins.

[0206] <Second embodiment> (1) Overall configuration The overall configuration of the structure system 2 according to the second embodiment will be described. Below, similarities between the first and second embodiments will be omitted, and differences between the first and second embodiments will be mainly described. Hereinafter, in the second embodiment, as in the first embodiment, front means the X direction, rear means the minus X direction, left means the minus Z direction, right means the Z direction, down means the minus Y direction, and up means the Y direction. Height is the distance in the Y direction from the soil S.

[0207] 40 is a schematic diagram showing the overall configuration of a structure system 2 according to the second embodiment. The structure system 2 mainly includes a greenhouse 10, an air conditioner 11, and a control device 26.

[0208] (1-1) Greenhouse A structure 100A and a structure 100B are mainly provided inside the green house 10. The green house 10, the air conditioner 11, the structure 100A, and the structure 100B are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0209] (1-2) Control Device The control device 26 mainly controls the structure 100A, the structure 100B, and the air conditioner 11. The control device 26 is connected to the structure 100A, the structure 100B, and the air conditioner 11 by wire or wirelessly. Details of the control device 26 will be described later. The location where the control device 26 is provided is not limited to the outside of the greenhouse 10. The control device 26 may be provided in at least one of the interior I1, the interior I2, and the space I3. The functions of the control device 26 may be realized on a server or on the cloud. The control device 26 may be connected to structures provided in multiple greenhouses 10.

[0210] (2) Detailed Configuration (2-1) Control Device The detailed configuration of the control device 26 will be described. Fig. 41 is a functional block diagram of the control device 26. The control device 26 mainly includes an information processing device 261, a structure control unit 162, and an air conditioning control unit 163. The structure control unit 162 and the air conditioning control unit 163 are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0211] (2-1-1) Information Processing Apparatus The information processing apparatus 261 mainly includes a space identification unit 2612, a reception unit 2613, a motion identification unit 1614, and a storage unit 2615. The motion identification unit 1614 is the same as in the first embodiment, and therefore a description thereof will be omitted.

[0212] (2-1-1-1) Space Identification Unit The space identification unit 2612 identifies space information for each period of the structure control period based on the growth information.

[0213] (2-1-1-1-1) Growth Information The growth information will be explained below. Growth information is time-series information that associates time with at least one of the values ​​of the height of the plant P, the change in height of the plant P, the width of the plant P, the change in width of the plant P, the depth of the plant P, and the change in depth of the plant P. "Time" may be either what is called time (a certain moment in the flow of time) or what is called duration (the length between one time and another time).

[0214] 42, 43, and 44 are diagrams showing examples of growth information. The growth information in Fig. 42 is information that associates a date with a height value of a plant P. The growth information in Fig. 43 is information that associates a period with a change in height of a plant P. The growth information in Fig. 44 is information that associates a period with a change in height of a plant P.

[0215] The growth information is recorded in advance in the storage unit 2615, or is input to the control device 26 by a user or an external device (not shown). Alternatively, the growth information may be input to the control device 26 from outside via a network by real-time processing or batch processing. Although not shown, the growth information may also include any of the width value of the plant P, the change in width of the plant P, the depth value of the plant P, and the change in depth of the plant P.

[0216] (2-1-1-1-2) Processing of Space Identification Unit An example of processing by the space identification unit 2612 will be described. The space identification unit 2612 identifies the depth value of the interior I1 as the depth value of the necessary space N. The space identification unit 2612 identifies the width value of the interior I1 as the width value of the necessary space N. The space identification unit 2612 identifies the bottom surface of the necessary space N to be parallel to the soil S. The space identification unit 2612 identifies the top surface of the necessary space N to be parallel to the soil S. The space identification unit 2612 identifies the height of the plant P on the date associated with the identified necessary space N as the height of the bottom surface of the necessary space N. The space identification unit 2612 identifies the height of the plant P one structure control cycle after the date associated with the identified necessary space N as the height of the top surface of the necessary space N.

[0217] A specific example of the processing of the space specifying unit 2612 when the growth information is the growth information of FIG. 42 and the structure control cycle is 15 days will be described. First, the space specifying unit 2612 specifies the necessary space N in association with the sowing date. The space specifying unit 2612 specifies 0 cm (height of the plant P) in the growth information, which is associated with the sowing date (date). The space specifying unit 2612 specifies 30 cm (height of the plant P) in the growth information, which is associated with the day (date) that is 15 days after the sowing date. The space specifying unit 2612 specifies the necessary space N in which the height of the bottom surface of the necessary space N is 0 cm and the height of the top surface of the necessary space N is 30 cm. The space specifying unit 2612 specifies the necessary space N in FIG. 8. The space specifying unit 2612 specifies the space information by associating the necessary space N in FIG. 8 with the sowing date (date).

[0218] Next, the spatial identification unit 2612 identifies spatial information for the day 15 days after sowing, the day 30 days after sowing, the day 45 days after sowing, and the day 60 days after sowing, in the same manner as the above process. As a result, the spatial identification unit 2612 identifies the spatial information in FIG. 13 based on the growth information in FIG. 42.

[0219] A specific example of the processing of the space specifying unit 2612 when the growth information is the growth information in FIG. 43 and the structure control cycle is 15 days will be described. First, the space specifying unit 2612 specifies the necessary space N to be associated with the sowing date. The space specifying unit 2612 divides 8 cm (the change in height of the plant P) in the growth information by 4 days (the period) in the growth information. The space specifying unit 2612 specifies 2 cm / day (the change in height of the plant P per period).

[0220] The space specification unit 2612 multiplies 2 cm / day (the change in height of the plant P per period) by 0 days (the period elapsed since the sowing date) to specify 0 cm (the height of the plant P on the sowing date). The space specification unit 2612 also multiplies 2 cm / day (the change in height of the plant P per period) by 15 days (the period elapsed since the sowing date) to specify 30 cm (the height of the plant P on the day 15 days after the sowing date). The space specification unit 2612 specifies the required space N by setting the height of the bottom surface of the required space N to 0 cm and the height of the top surface of the required space N to 30 cm. The space specification unit 2612 specifies the required space N in FIG. 8 . The space specification unit 2612 specifies the space information by associating the required space N in FIG. 8 with the sowing date (date).

[0221] Next, the spatial identification unit 2612 identifies spatial information for the day 15 days after sowing, the day 30 days after sowing, the day 45 days after sowing, and the day 60 days after sowing, in the same manner as the above process. As a result, the spatial identification unit 2612 identifies the spatial information in FIG. 13 based on the growth information in FIG. 43.

[0222] A specific example of the processing of the space specifying unit 2612 when the growth information is the growth information in FIG. 44 and the structure control cycle is 15 days will be described. First, the space specifying unit 2612 specifies the necessary space N to be associated with the sowing date. From the growth information, the space specifying unit 2612 specifies 30 cm (the change in height of the plant P) associated with the period from the sowing date to the day 15 days after the sowing date.

[0223] The space specification unit 2612 specifies the height of the plant P on the sowing date as 0 cm. The space specification unit 2612 adds 30 cm (the change in height of the plant P from the sowing date to the day 15 days after the sowing date) to 0 cm (the height of the plant P on the sowing date) to specify 30 cm (the height of the plant P on the day 15 days after the sowing date). The space specification unit 2612 specifies the necessary space N by setting the height of the bottom surface of the necessary space N to 0 cm and the height of the top surface of the necessary space N to 30 cm. The space specification unit 2612 specifies the necessary space N in FIG. 8. The space specification unit 2612 specifies space information by associating the necessary space N in FIG. 8 with the sowing date (date).

[0224] Next, the spatial identification unit 2612 identifies spatial information for the day 15 days after sowing, the day 30 days after sowing, the day 45 days after sowing, and the day 60 days after sowing, in the same manner as the above process. As a result, the spatial identification unit 2612 identifies the spatial information in FIG. 13 based on the growth information in FIG. 44.

[0225] The space specifying unit 2612 may specify only the space information relating to the current date, or may specify the space information relating to a future date in advance.

[0226] (2-1-1-2) Reception Unit The reception unit 2613 receives the space information identified by the space identification unit 2612. The reception unit 2613 records the received space information in the storage unit 2615. Note that the reception unit 2613 may receive space information from a user or an external device (not shown) in addition to the space information identified by the space identification unit 2612. Note that the reception unit 2613 may receive space information from the outside via a network in real-time processing or badge processing in addition to the space information identified by the space identification unit 2612.

[0227] (2-1-1-3) Storage Unit The storage unit 2615 stores the spatial information received by the receiving unit 2613. The storage unit 2615 also stores the motion information identified by the motion identification unit 1614. Examples of the storage unit 2615 include an HDD and an SSD. The storage unit 2615 may also store growth information input to the control device 26.

[0228] (3) Operation The operation of the structure system 2 from the sowing date to the harvest date will be described. Since the structure 100B operates in the same manner as the structure 100A, the operation of the structure 100A will be mainly described. The growth information used by the space specification unit 2612 is assumed to be any one of the growth information in FIG. 42, the growth information in FIG. 43, and the growth information in FIG. 44. The growth end date and the harvest date are assumed to be 60 days after the sowing date. The air conditioning control unit 163 is assumed to control the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I1 is suitable for growing the plant P.

[0229] Figure 45 is a flowchart showing the operation of the structure system 2. Step S41 is the same as step S1 in Figure 22. Step S42 is the same as step S2 in Figure 22. On the sowing day, the height of the ceiling 150 is 60 cm.

[0230] On the sowing date, the space specifying unit 2612 specifies space information that associates the sowing date (date) with the three-dimensional coordinates (necessary space N) of the required space N in Figure 8 based on the growth information (step S43). The receiving unit 2613 receives the space information and records it in the storage unit 2615.

[0231] Step S44 is the same as step S3 in Fig. 22. Step S45 is the same as step S4 in Fig. 22. The height of the ceiling 150 remains at 60 cm.

[0232] On the day 15 days after the sowing date, the space specifying unit 2612 specifies space information that associates the day (date) 15 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 9 based on the growth information (step S46). The receiving unit 2613 receives the space information and records it in the storage unit 2615.

[0233] Step S47 is the same as step S5 in Fig. 22. Step S48 is the same as step S6 in Fig. 22. The height of the ceiling 150 remains at 60 cm.

[0234] On the day 30 days after the sowing date, the space specifying unit 2612 specifies space information that associates the day (date) 30 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 10 based on the growth information (step S49). The receiving unit 2613 receives the space information and records it in the storage unit 2615.

[0235] Step S50 is the same as step S7 in Fig. 22. Step S51 is the same as step S8 in Fig. 22. The height of the ceiling 150 changes from 60 cm to 90 cm. The volume of the interior I1 increases.

[0236] On the day 45 days after the sowing date, the space specifying unit 2612 specifies, based on the growth information, space information that associates the day (date) 45 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 11 (step S52). The receiving unit 2613 receives the space information and records it in the storage unit 2615.

[0237] Step S53 is the same as step S9 in Fig. 22. Step S54 is the same as step S10 in Fig. 22. The height of the ceiling 150 changes from 90 cm to 120 cm. The volume of the interior I1 increases.

[0238] On the day 60 days after the sowing date, the space specifying unit 2612 specifies space information that associates the day (date) 60 days after the sowing date with "none" (necessary space N) based on the growth information (step S55). The receiving unit 2613 receives the space information and records it in the storage unit 2615.

[0239] Step S56 is the same as step S11 in Fig. 22. Step S57 is the same as step S12 in Fig. 22. The height of the ceiling 150 remains at 120 cm.

[0240] Step S58 is the same as step S13 in Fig. 22. Step S59 is the same as step S14 in Fig. 22.

[0241] (4) Features (4-1) The information processing device 261 further includes a space specification unit 2612 that specifies spatial information based on growth information that is time-series information that associates time with at least any one of the values ​​of the height of the plant P, the change in the height of the plant P, the width of the plant P, the change in the width of the plant P, the depth of the plant P, and the change in the depth of the plant P. A receiving unit 2613 of the information processing device 261 receives the spatial information specified by the space specification unit 2612.

[0242] The height, width, and depth of a plant can change over time. Therefore, the volume of space required by the plant can change over time. If air conditioning is performed for the maximum space required by the plant before the plant has finished growing, energy will be wasted on the space.

[0243] The information processing device 261 identifies spatial information based on growth information that associates time with the height of the plant P, etc. Therefore, the information processing device 261 can achieve energy savings in cultivating the plant P in the interiors I1 and I2, and can reduce the cost of cultivating the plant P.

[0244] (5) Modifications A modification of the second embodiment will be described, focusing on the differences from the second embodiment, and omitting the description of the similarities to the second embodiment.

[0245] (5-1) Modification 2A The control device 26 may control the structure 100A, the structure 100B, the rack R1, the rack R2, etc. that are provided inside the plant factory 20 instead of the inside of the greenhouse 10. In modification 2A, the height is the distance in the Y direction from the ground F, except in cases where it is described as a relative height.

[0246] The space specifying unit 2612 specifies the depth value of rack R1 as the depth value of the required space N. The space specifying unit 2612 specifies the width value of rack R1 as the width value of the required space N. The space specifying unit 2612 specifies the bottom surface of the required space N to be parallel to the ground F. The space specifying unit 2612 specifies the top surface of the required space N to be parallel to the ground F.

[0247] The space specification unit 2612 specifies the height of the plant P (height relative to each unit) on the date associated with the specified necessary space N as the height (height relative to each unit) of the bottom surface of the necessary space N. The space specification unit 2612 specifies the height of the plant P (height relative to each unit) one structure control cycle after the date associated with the specified necessary space N as the height of the top surface of the necessary space N (height relative to each unit).

[0248] <Third Embodiment> (1) Overall Configuration The overall configuration of the structure system 3 according to the third embodiment will be described. Below, similarities between the second and third embodiments will be omitted, and differences between the second and third embodiments will be mainly described. In the third embodiment, unlike the first and second embodiments, front means the negative Z direction, rear means the Z direction, left means the negative X direction, right means the X direction, down means the negative Y direction, and up means the Y direction. Height is the distance in the Y direction from the soil S.

[0249] 46 is a schematic diagram showing the overall configuration of a structure system 3 according to the third embodiment. The structure system 3 mainly includes a greenhouse 10, an air conditioner 11, and a control device 36.

[0250] (1-1) Greenhouse 10 A structure 300 is mainly provided inside the greenhouse 10. The structure 300 divides the inside of the greenhouse 10 into an interior I4 of the structure 300 and a space I5 outside the structure 300 and inside the greenhouse 10. Details of the structure 300 will be described later.

[0251] (1-2) Air Conditioner The air conditioner 11 conditions the air in the interior 14. The air conditioner 11 is connected to the interior 14 via a hose (not shown). The air conditioned by the air conditioner 11 is supplied to the interior 14 via the hose or the like.

[0252] (1-3) Control Device The control device 36 mainly controls the structure 300 and the air conditioner 11. The control device 36 is connected to the structure 300 and the air conditioner 11 by wire or wirelessly. Details of the control device 36 will be described later.

[0253] (2) Detailed Configuration (2-1) Structure 300 A detailed configuration of the structure 300 will be described. The structure 300 is a variable structure in which the volume of the interior I4 can be changed by the operation of the structure 300.

[0254] 47 is a configuration diagram showing a detailed configuration of the structure 300. The structure 300 mainly has a first front movable wall 311, a second front movable wall 312, a left fixed wall 321, a left movable wall 322, a right fixed wall 331, a right movable wall 332, a rear fixed wall 341, a rear movable wall 342, and a ceiling 350.

[0255] Examples of configurations of the first front movable wall 311, the second front movable wall 312, the left fixed wall 321, the left movable wall 322, the right fixed wall 331, the right movable wall 332, the rear fixed wall 341, the rear movable wall 342, and the ceiling 350 include, but are not limited to, a configuration of a framework and vinyl covering the framework, a configuration of a framework and glass covering the framework, a configuration of a framework and a plastic film covering the framework, and a configuration in which the framework and a surface covering the framework are integrated.

[0256] When lighting is provided in space I5, at least one of the first front movable wall 311, the second front movable wall 312, the left fixed wall 321, the left movable wall 322, the right fixed wall 331, the right movable wall 332, the rear fixed wall 341, the rear movable wall 342, and the ceiling 350 may be configured to include transparent or translucent vinyl, glass, or plastic film so that light from the lighting in space I5 is transmitted to the interior I4.

[0257] The left fixed wall 321, the right fixed wall 331, and the rear fixed wall 341 are fixed to the soil S and are provided in a direction generally perpendicular to the soil S (Y direction). The left fixed wall 321 is provided with an opening 323 that communicates with a hose. Air conditioned by the air conditioner 11 is supplied to the interior 14 through the opening 323.

[0258] The ceiling 350 is generally parallel to the soil S. The second front movable wall 312, the left movable wall 322, the right movable wall 332, and the rear movable wall 342 are connected to the ceiling 350 at the four corners of the ceiling 350. Therefore, the second front movable wall 312, the left movable wall 322, the right movable wall 332, the rear movable wall 342, and the ceiling 350 form a single member.

[0259] The space surrounded by the soil S, the first front movable wall 311, the left fixed wall 321, the right fixed wall 331, and the rear fixed wall 341 is covered from above by a member formed by the second front movable wall 312, the left movable wall 322, the right movable wall 332, the rear movable wall 342, and the ceiling 350. The interior I4 is isolated from the outside of the structure 300 (space I5) by the structure 300.

[0260] The second front movable wall 312 is located behind (in the Z direction) the first front movable wall 311 and is generally perpendicular to the soil S. The left movable wall 322 is located to the right (in the X direction) of the left fixed wall 321 and is generally perpendicular to the soil S. The right movable wall 332 is located to the left (in the negative X direction) of the right fixed wall 331 and is generally perpendicular to the soil S. The rear movable wall 342 is located in front (in the negative Z direction) of the rear fixed wall 341 and is generally perpendicular to the soil S.

[0261] The first front movable wall 311 mainly has a fixed plate 3111, a fixed plate 3112, a movable plate 3113, and a ninth guide rail 3114. The fixed plate 3111 and the fixed plate 3112 are fixed to the soil S and are arranged in a direction generally perpendicular to the soil S. The ninth guide rail 3114 is fixed to the soil S. The movable plate 3113 is guided by the ninth guide rail 3114 and is arranged to slide in the X direction or the negative X direction. The movable plate 3113 is positioned in front of the fixed plate 3112 (in the negative Z direction) so that it does not overlap with the fixed plate 3112 even when the movable plate 3113 slides in the X direction.

[0262] The movable plate 3113 may be configured to be able to open and close by rotating about an axis (not shown, generally perpendicular to the soil S) provided at the right end of the movable plate 3113 or an axis (not shown, generally perpendicular to the soil S) provided at the left end of the movable plate 3113. In this case, the first front movable wall 311 does not include the ninth guide rail 3114.

[0263] A plant P is cultivated in the interior I4. In the interior I4, soil S in which the plant P can be planted or a nutrient solution (not shown) in which the plant P can be soaked is stored. In the interior I4, the plant P is planted in the soil S or soaked in the nutrient solution. Note that the fact that the plant P is cultivated in the interior I4 does not mean that the plant P is always present in the interior I4. After the plant P is harvested, there may be cases where the plant P is not present in the interior I4. Furthermore, even if the plant P is present in the interior I4, there may be cases where the plant P has just been planted, and therefore the plant P has not yet germinated, or the plant P cannot be seen with the naked eye in the interior I4.

[0264] The left fixed wall 321, the right fixed wall 331, and the rear fixed wall 341 are non-movable components. The first front movable wall 311, the second front movable wall 312, the left movable wall 322, the right movable wall 332, the rear movable wall 342, and the ceiling 350 are movable components. Below, a description will be given of a variation method that can be adopted for the structure 300.

[0265] (2-1-1) Variable method (2-1-1-1) Movable side wall method The movable side wall method is a method for changing the internal volume of a structure that includes a first side wall that is movably arranged in a direction generally perpendicular to the ground, and a second side wall that is movably arranged in a direction generally perpendicular to the ground, by moving the first side wall and the second side wall in a direction generally perpendicular to the ground.

[0266] 48 and 49 are diagrams showing an example of a method for moving the side walls. The left movable wall 322 is a first side wall that is movable in a direction (Y direction) generally perpendicular to the ground (soil S). The right movable wall 332 is a second side wall that is movable in a direction (Y direction) generally perpendicular to the ground (soil S).

[0267] Actuators (not shown) convert electricity, air pressure, hydraulic pressure, etc. into physical movement (mechanical operation) to move the left movable wall 322 and the right movable wall 332 in a direction generally perpendicular to the ground. When the left movable wall 322 and the right movable wall 332 in FIG. 48 are moved upward (in the Y direction) by the actuators, they can change into the state of the left movable wall 322 and the right movable wall 332 in FIG. 49. As the left movable wall 322 and the right movable wall 332 rise, the ceiling 350 connected to the left movable wall 322 and the right movable wall 332 is also raised. The second front movable wall 312 and the rear movable wall 342 connected at the corners of the ceiling 350 are also raised along with the ceiling 350. This increases the volume of the interior I4.

[0268] When the left movable wall 322 and the right movable wall 332 in Fig. 49 are moved downward (in the negative Y direction) by the actuator, they can change to the state of the left movable wall 322 and the right movable wall 332 in Fig. 48. As the left movable wall 322 and the right movable wall 332 are lowered, the ceiling 350 connected to the left movable wall 322 and the right movable wall 332 is also lowered. The second front movable wall 312 and the rear movable wall 342 connected at the corners of the ceiling 350 are also lowered along with the ceiling 350. This reduces the volume of the interior I4.

[0269] (2-1-1-2) Other Methods The method of varying the structure 300 may be any other variation method that a person skilled in the art can imagine, and is not limited to the above examples. For example, in a structure including a first side wall that is movably mounted on the ground in a generally horizontal direction (X direction or Z direction) and a second side wall that is movably mounted on the ground in a generally horizontal direction, the internal volume of the structure may be changed by moving the first side wall and the second side wall in a generally horizontal direction. In a structure including a ceiling that is movably mounted on the ground in a generally horizontal direction, the internal volume of the structure may be changed by moving the ceiling in a generally horizontal direction.

[0270] (2-1-2) Aspect of the structure 300 when agricultural work is being performed Below, the aspect of the structure 300 when agricultural work is being performed will be described. When agricultural work is being performed, the aspect of the structure 300 changes to ensure the space necessary for the work. Figure 50 is a diagram showing an example of the aspect of the structure 300 when agricultural work is being performed. When agricultural work is being performed, the movable plate 3113 slides in the X direction. The interior I4 communicates with the entrance / exit 101 via the front (negative Z direction) side and with the outside of the greenhouse 10. Therefore, people or equipment can move to the interior I4 and agricultural work can be performed in the interior I4.

[0271] When agricultural work is performed, other aspects of the structure 300 that can be imagined by a person skilled in the art may be realized, and the structure 300 is not limited to the above example.

[0272] (2-2) Control Device A detailed configuration of the control device 36 will be described. Fig. 51 is a functional block diagram of the control device 36. The control device 36 mainly includes an information processing device 361, a structure control unit 362, and an air conditioning control unit 363.

[0273] (2-2-1) Information Processing Device The information processing device 361 mainly includes a growth specifying unit 3611 , a space specifying unit 3612 , a receiving unit 3613 , an action specifying unit 3614 , and a storage unit 3615 .

[0274] (2-2-1-1) Growth Identification Unit The growth identification unit 3611 identifies growth information based on type information, environmental information, and basic information. The growth identification unit 3611 records the identified growth information in the storage unit 3615. The type information, environmental information, and basic information will be described below.

[0275] (2-2-1-1-1) Type Information Type information is information indicating the type of plant P. Examples of the type of plant P include the variety of plant P, the item of plant P, the scientific name of plant P, the trade name of plant P, the name of a gene related to plant P, the lineage of plant P, and the biological classification of plant P. FIG. 52 is a diagram showing an example of type information. The type information in FIG. 52 is information indicating the variety (major classification) of plant P and the variety (minor classification) of plant P.

[0276] (2-2-1-1-2) Environmental Information The environmental information is information indicating at least one of the physical and chemical environments of the interior I4, and indicating elements of the environment that affect the growth of the plant P. Specifically, the environmental information is information indicating at least one of the temperature of the interior I4, the humidity of the interior I4, the illuminance of light in the interior I4, the duration of light exposure in the interior I4, the components of the air in the interior I4, the amount of water given to the plant P, the amount of fertilizer given to the plant P, the components of the fertilizer given to the plant P, the components of the soil S in which the plant P is planted, and the components of the nutrient solution in which the plant P is immersed. FIG. 53 is a diagram showing an example of environmental information. The environmental information in FIG. 53 is information indicating the temperature of the interior I4 and the humidity of the interior I4.

[0277] The illuminance of light in the interior I4 may be the ratio of the illuminance of light in the interior I4 to the light saturation point of the plant P, or may be the ratio of the illuminance of light in the interior I4 to the light compensation point of the plant P. The environmental information may be time-series information relating time to at least one of the physical and chemical environments in the interior I4, and relating environmental elements that affect the growth of the plant P. Fig. 54 is a diagram showing an example of environmental information. The environmental information in Fig. 54 is information indicating a period and the temperature of the interior I4.

[0278] (2-2-1-1-3) Basic Information Basic information is information in which type information, environmental information, and growth information are associated with each other. FIG. 55 is a diagram showing an example of basic information. The basic information in FIG. 55 is information in which the variety (major category) of the plant P, the variety (minor category) of the plant P, the temperature of the interior I4, the humidity of the interior I4, a period, and a change in height of the plant P are associated with each other. FIG. 56 is a diagram showing an example of basic information. The basic information in FIG. 56 is information in which the variety (major category) of the plant P, the variety (minor category) of the plant P, the temperature of the interior I4, a period, and a change in height of the plant P are associated with each other.

[0279] The type information, environmental information, and basic information may be recorded in advance in the storage unit 3615, or may be input to the control device 36 by a user or an external device (not shown). Alternatively, the type information, environmental information, and basic information may be input to the control device 36 from outside via a network by real-time processing or badge processing. The environmental information may be received by a sensor (not shown).

[0280] (2-2-1-1-4) Processing of the Growth Identification Unit An example of processing of the growth identification unit 3611 will be described. The growth identification unit 3611 reads type information, environmental information, and basic information. The growth identification unit 3611 compares the type information and environmental information with the basic information to identify growth information.

[0281] A specific example of the processing of the growth identification unit 3611 when the type information is the type information of FIG. 52 , the environmental information is the environmental information of FIG. 53 , and the basic information is the basic information of FIG. 55 will be described. The growth identification unit 3611 reads the type information of FIG. 52 , the environmental information of FIG. 53 , and the basic information of FIG. 55 . Of the basic information, the growth identification unit 3611 identifies, as growth information, one day (period) and 1.6 cm (change in height of plant P) associated with cherry tomato (a variety (major category) of plant P), mini carol (a variety (minor category) of plant P), 23° C. (temperature of interior I4), and 75% (humidity of interior I4). FIG. 57 is a diagram showing an example of growth information. The growth identification unit 3611 identifies the growth information of FIG. 57 through the above processing.

[0282] A specific example of processing by the growth identification unit 3611 when the type information is the type information in FIG. 52 , the environmental information is the environmental information in FIG. 54 , and the basic information is the basic information in FIG. 56 will be described. The growth identification unit 3611 reads the type information in FIG. 52 , the environmental information in FIG. 54 , and the basic information in FIG. 56 . Of the basic information, the growth identification unit 3611 identifies, as growth information, cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P), the period from the sowing date to the day 30 days after the sowing date (period), and 20 cm (a change in the height of plant P) associated with 25° C. (temperature of internal I4).

[0283] In addition, the growth identification unit 3611 identifies, from the basic information, cherry tomato (a variety (major category) of plant P), mini carol (a variety (minor category) of plant P), the period from 30 days after sowing to 60 days after sowing, the period from 30 days after sowing to 60 days after sowing associated with 20°C (temperature of internal I4), and 40 cm (change in height of plant P) as growth information.

[0284] Furthermore, the growth identification unit 3611 identifies, from the basic information, cherry tomato (a variety (major category) of plant P), mini carol (a variety (minor category) of plant P), the period from 60 days after sowing to 90 days after sowing, the period from 60 days after sowing to 90 days after sowing associated with 20°C (temperature of internal I4), and 60 cm (change in height of plant P) as growth information.

[0285] In addition, the growth identification unit 3611 identifies, from the basic information, cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P), the period from 90 days after sowing to 120 days after sowing, the period from 90 days after sowing to 120 days after sowing associated with 20°C (temperature of internal I4), and 90 cm (a change in the height of plant P) as growth information. FIG. 58 is a diagram showing an example of growth information. The growth identification unit 3611 identifies the growth information of FIG. 58 through the above process.

[0286] (2-2-1-2) Space Identification Unit The space identification unit 3612 identifies space information for each period of the structure control period based on the growth information.

[0287] A specific example of processing by the space specifying unit 3612 when the growth information is the growth information in FIG. 58 and the structure control cycle is 30 days will be described. First, the space specifying unit 3612 specifies the necessary space N associated with the sowing date. From the growth information, the space specifying unit 3612 specifies 20 cm (the change in height of the plant P) associated with the period from the sowing date to the day 30 days after the sowing date.

[0288] The space specification unit 3612 specifies the height of the plant P on the sowing date as 0 cm. The space specification unit 3612 adds 20 cm (the change in height of the plant P from the sowing date to the day 30 days after the sowing date) to 0 cm (the height of the plant P on the sowing date) to specify 20 cm (the height of the plant P on the day 30 days after the sowing date). The space specification unit 3612 specifies the necessary space N by setting the height of the bottom surface of the necessary space N to 0 cm and the height of the top surface of the necessary space N to 20 cm. Figure 59 is a diagram showing an example of the necessary space N. The space specification unit 3612 specifies the necessary space N in Figure 59. The space specification unit 3612 specifies space information by associating the necessary space N in Figure 59 with the sowing date (date).

[0289] Next, the space specifying unit 3612 specifies the required space N to be associated with the day 30 days after the sowing date. The space specifying unit 3612 specifies, from the growth information, 40 cm (the change in height of the plant P) associated with the period from the day 30 days after the sowing date to the day 60 days after the sowing date.

[0290] The space specification unit 3612 has already specified the height of the plant P as 20 cm on the day 30 days after the sowing date. The space specification unit 3612 adds 40 cm (the change in height of the plant P from the day 30 days after the sowing date to the day 60 days after the sowing date) to 20 cm (the height of the plant P on the day 30 days after the sowing date) to specify 60 cm (the height of the plant P on the day 60 days after the sowing date). The space specification unit 3612 specifies the necessary space N by setting the height of the bottom surface of the necessary space N to 20 cm and the height of the top surface of the necessary space N to 60 cm. Figure 60 is a diagram showing an example of the necessary space N. The space specification unit 3612 specifies the necessary space N in Figure 60. The space specification unit 3612 specifies space information by associating the necessary space N in Figure 60 with the day (date) 30 days after the sowing date.

[0291] Next, the space specifying unit 3612 specifies the required space N to be associated with the day 60 days after the sowing date. The space specifying unit 3612 specifies, from the growth information, 60 cm (the change in height of the plant P) associated with the period from the day 60 days after the sowing date to the day 90 days after the sowing date.

[0292] The space specification unit 3612 has already specified the height of the plant P as 60 cm on the day 60 days after the sowing date. The space specification unit 3612 adds 60 cm (the change in height of the plant P from the day 60 days after the sowing date to the day 90 days after the sowing date) to 60 cm (the height of the plant P on the day 90 days after the sowing date) to specify 120 cm (the height of the plant P on the day 90 days after the sowing date). The space specification unit 3612 specifies the required space N by setting the height of the bottom surface of the required space N to 60 cm and the height of the top surface of the required space N to 120 cm. FIG. 61 is a diagram showing an example of the required space N. The space specification unit 3612 specifies the required space N in FIG. 61. The space specification unit 3612 specifies space information by associating the required space N in FIG. 61 with the day (date) 60 days after the sowing date.

[0293] Next, the space specifying unit 3612 specifies the required space N to be associated with the day 90 days after the sowing date. The space specifying unit 3612 specifies, from the growth information, 90 cm (the change in height of the plant P) associated with the period from the day 90 days after the sowing date to the day 120 days after the sowing date.

[0294] The space specification unit 3612 has already specified the height of the plant P as 120 cm on the day 90 days after the sowing date. The space specification unit 3612 adds 90 cm (the change in height of the plant P from the day 90 days after the sowing date to the day 120 days after the sowing date) to 120 cm (the height of the plant P on the day 90 days after the sowing date) to specify 210 cm (the height of the plant P on the day 120 days after the sowing date). The space specification unit 3612 specifies the required space N by setting the height of the bottom surface of the required space N to 120 cm and the height of the top surface of the required space N to 210 cm. Figure 62 is a diagram showing an example of the required space N. The space specification unit 3612 specifies the required space N in Figure 62. The space specification unit 3612 specifies space information by associating the required space N in Figure 62 with the day (date) 90 days after the sowing date.

[0295] Finally, the space specification unit 3612 specifies the required space N to be associated with the day 120 days after the sowing date. The growth information does not contain a change value in the height of the plant P associated with the period from the day 120 days after the sowing date to the day 150 days after the sowing date. Therefore, the space specification unit 3612 specifies that the required space N does not exist. The space specification unit 3612 specifies the space information by associating none (required space N) with the day (date) 120 days after the sowing date.

[0296] 63 is a diagram showing an example of space information. The space specifying unit 3612 specifies the space information in FIG. 63 through the above processing.

[0297] (2-2-1-3) Receiving Unit The receiving unit 3613 receives the space information specified by the space specifying unit 3612. The receiving unit 3613 records the received space information in the storage unit 3615.

[0298] (2-2-1-4) Motion Identification Unit The motion identification unit 3614 identifies motion information based on the spatial information stored in the storage unit 3615. The motion identification unit 3614 also records the identified motion information in the storage unit 3615.

[0299] Below, a specific example of the processing by the action identification unit 3614 when the spatial information is the spatial information of Fig. 63 will be described. Fig. 65, Fig. 66, Fig. 67, Fig. 68, Fig. 69, and Fig. 70 are diagrams showing examples of aspects of the structure 300.

[0300] FIG. 65 is a diagram showing an example of the state of the structure 300 on the sowing date. The height of the ceiling 350 on the sowing date is assumed to be 140 cm. On the sowing date, the action identification unit 3614 compares the three-dimensional coordinates of the required space N in FIG. 59 with the three-dimensional coordinates of the structure 300. The height of the ceiling 350 (140 cm) is higher than the height of the top surface of the required space N (20 cm). The action identification unit 3614 associates the sowing date with the fact that the ceiling 350 does not operate, thereby identifying action information. The action identification unit 3614 records the identified action information in the memory unit 3615.

[0301] FIG. 66 is a diagram showing an example of the state of the structure 300 30 days after the sowing date. The height of the ceiling 350 on the day 30 days after the sowing date is assumed to be 140 cm. On the day 30 days after the sowing date, the operation identification unit 3614 compares the three-dimensional coordinates of the required space N in FIG. 60 with the three-dimensional coordinates of the structure 300. The height of the ceiling 350 (140 cm) is higher than the height of the top surface of the required space N (60 cm). The operation identification unit 3614 identifies operation information by associating the day 30 days after the sowing date with the fact that the ceiling 350 is not operating. The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0302] FIG. 67 is a diagram showing an example of the state of the structure 300 60 days after the sowing date. Assume that the height of the ceiling 350 on the day 60 days after the sowing date is 140 cm. On the day 60 days after the sowing date, the operation identification unit 3614 compares the three-dimensional coordinates of the required space N in FIG. 61 with the three-dimensional coordinates of the structure 300. The height of the ceiling 350 (140 cm) is higher than the height of the top surface of the required space N (120 cm). The operation identification unit 3614 associates the day 60 days after the sowing date with the fact that the ceiling 350 is not operating, thereby identifying operation information. The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0303] FIG. 68 is a diagram showing an example of the state of the structure 300 90 days after the sowing date. Assume that the height of the ceiling 350 on the day 90 days after the sowing date is 140 cm. On the day 90 days after the sowing date, the action identification unit 3614 compares the three-dimensional coordinates of the required space N in FIG. 62 with the three-dimensional coordinates of the structure 300. The height of the ceiling 350 (140 cm) is approximately 70 cm lower than the height of the top surface of the required space N (210 cm). The action identification unit 3614 determines that the ceiling 350 will move 70 cm in the Y direction to secure the required space N in the interior I4. The action identification unit 3614 identifies action information by associating the day 90 days after the sowing date with the fact that the ceiling 350 will move 70 cm in the Y direction. The action identification unit 3614 records the identified action information in the storage unit 3615.

[0304] FIG. 70 is a diagram showing an example of the state of the structure 300 on the day 120 days after the sowing date. Assume that the height of the ceiling 350 on the day 120 days after the sowing date is 210 cm. On the day 120 days after the sowing date, the operation identification unit 3614 identifies that there is no required space N associated with the day 120 days after the sowing date. The operation identification unit 3614 identifies operation information by associating the day 120 days after the sowing date with the fact that the ceiling 350 does not operate. The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0305] 64 is a diagram showing an example of the motion information. The motion identification unit 3614 identifies the motion information in FIG. 64 through the above processing.

[0306] (2-2-1-5) Storage Unit The storage unit 3615 stores the growth information identified by the growth identification unit 3611. The storage unit 3615 stores the space information received by the reception unit 3613. The storage unit 3615 also stores the motion information identified by the motion identification unit 3614. Examples of the storage unit 3615 include an HDD and an SSD.

[0307] (2-2-2) Structure Control Unit The structure control unit 362 controls the structure 300 so that the structure 300 secures the required space N through its operation.

[0308] Below, a specific example of the processing by the structure control unit 362 when the operation information is the operation information in Fig. 64 and the structure control period is 30 days will be described. The state of the structure 300 on the sowing day is the state of the structure 300 in Fig. 65. On the sowing day, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate.

[0309] The state of the structure 300 on the day 30 days after the sowing date is the state of the structure 300 in Fig. 66. On the day 30 days after the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate.

[0310] The state of the structure 300 60 days after the sowing date is the state of the structure 300 in Fig. 67. On the day 60 days after the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate.

[0311] The state of the structure 300 90 days after the sowing date is the state of the structure 300 in Figure 68. On the day 90 days after the sowing date, the structure control unit 362 moves the ceiling 350 by 70 cm in the Y direction. The state of the structure 300 in Figure 68 becomes the state of the structure 300 in Figure 69 due to the movement of the ceiling 350. The height of the ceiling 350 in Figure 69 is 70 cm higher in the Y direction than the height of the ceiling 350 in Figure 68.

[0312] The state of the structure 300 on the day 120 days after the sowing date is the state of the structure 300 in Fig. 70. On the day 120 days after the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate.

[0313] The structure control unit 362 controls the structure 300 to realize the state of the structure 300 when agricultural work is being performed. Before the agricultural work begins, the structure control unit 362 moves the ceiling 350 in the Y direction to set the height of the ceiling 350 to 210 cm, and moves the movable plate 3113 in the X direction to move the ceiling 350 120 cm in the X direction from the state shown in FIG. 49 . In this way, the structure control unit 362 realizes the state of the structure 300 shown in FIG. 50 . After the agricultural work is completed, the structure control unit 362 moves the ceiling 350 in the negative Y direction and moves the movable plate 3113 in the negative X direction to realize the state of the structure 300 before the agricultural work.

[0314] (2-2-3) Air Conditioning Control Unit The air conditioning control unit 363 controls the air conditioner 11 so that the interior I4 and the space I5 have different temperatures or humidities. Except when agricultural work is being performed (when the structure 300 is in the configuration shown in FIG. 50), the interior I4 is not in communication with the space I5 (except for gaps between the components of the structure 300). Air conditioned by the air conditioning control unit 363 does not easily flow from the interior I4 to the space I5. As a result, the interior I4 and the space I5 have different temperatures or humidities.

[0315] (3) Operation The operation of the structure system 3 from the sowing date to the harvest date will be described. Assume that the type information in FIG. 52, the environmental information in FIG. 54, and the basic information in FIG. 56 are input to the control device 36. Assume that the structure control cycle is 30 days. Assume that the harvest date is 120 days after the sowing date. Assume that the air conditioning control unit 363 controls the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I4 is suitable for cultivating the plants P.

[0316] Figure 71 is a flowchart showing the operation of the structure system 3. On the sowing day, the structure control unit 362 moves the ceiling 350 in the Y direction and the movable plate 3113 in the X direction to realize the configuration of the structure 300 in Figure 50 (step S61). A person or a device performs the work of sowing plants P in the interior I4.

[0317] On the sowing day, after the sowing work is completed, the structure control unit 362 moves the ceiling 350 in the negative Y direction and the movable plate 3113 in the negative X direction to realize the structure 300 shown in Figure 65 (step S62). Since it is immediately after sowing, the plants P have not yet germinated. The height of the ceiling 350 is 140 cm.

[0318] On the sowing date, the growth specification unit 3611 reads the type information in Fig. 52, the environmental information in Fig. 54, and the basic information in Fig. 56. The growth specification unit 3611 specifies the growth information in Fig. 58 (step S63). The growth specification unit 3611 records the specified growth information in the storage unit 3615.

[0319] On the sowing date, the space specifying unit 3612 specifies space information that associates the sowing date (date) with the three-dimensional coordinates (required space N) of the required space N in Figure 59 based on the growth information in Figure 58 (step S64). The receiving unit 3613 receives the space information and records it in the storage unit 3615.

[0320] The operation identification unit 3614 identifies operation information by associating the sowing date with the fact that the ceiling 350 does not operate (step S65). The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0321] On the sowing day, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate (step S66). The height of the ceiling 350 remains at 140 cm.

[0322] After 30 days from the date of sowing, the height of the plant P is approximately 20 cm. Therefore, the structure 300 and the plant P have the configuration shown in FIG.

[0323] On the day 30 days after the sowing date, the space specifying unit 3612 specifies space information that associates the day (date) 30 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 60 based on the growth information in Figure 58 (step S67). The receiving unit 3613 receives the space information and records it in the storage unit 3615.

[0324] On the day 30 days after the sowing date, the operation identification unit 3614 identifies operation information by associating the day 30 days after the sowing date with the fact that the ceiling 350 does not operate (step S68). The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0325] On the day 30 days after the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate (step S69). The height of the ceiling 350 remains at 140 cm.

[0326] After 60 days have passed since the sowing date, the height of the plant P will be approximately 60 cm. Therefore, the structure 300 and the plant P will be in the form of the structure 300 and the plant P shown in FIG.

[0327] On the day 60 days after the sowing date, the space specifying unit 3612 specifies space information that associates the day (date) 60 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 61 based on the growth information in Figure 58 (step S70). The receiving unit 3613 receives the space information and records it in the storage unit 3615.

[0328] On the day 60 days after the sowing date, the operation identification unit 3614 identifies operation information by associating the day 60 days after the sowing date with the fact that the ceiling 350 does not operate (step S71). The operation identification unit 3614 records the identified operation information in the storage unit 3615.

[0329] On the day 60 days after the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate (step S72). The height of the ceiling 350 remains at 140 cm.

[0330] After 90 days have passed since the sowing date, the height of the plant P will be approximately 120 cm. Therefore, the structure 300 and the plant P will be in the form of the structure 300 and the plant P shown in FIG.

[0331] On the day 90 days after the sowing date, the space specifying unit 3612 specifies space information that associates the day (date) 90 days after the sowing date with the three-dimensional coordinates of the required space N (required space N) in Figure 62 based on the growth information in Figure 58 (step S73). The receiving unit 3613 receives the space information and records it in the storage unit 3615.

[0332] On the day 90 days after the sowing date, the operation identification unit 3614 identifies operation information by associating the day 90 days after the sowing date with the fact that the ceiling 350 will move 70 cm in the Y direction (step S74).

[0333] On the day 90 days after the sowing date, the structure control unit 362 moves the ceiling 350 by 70 cm in the Y direction (step S75). The structure 300 in Figure 68 becomes the structure 300 in Figure 69 due to the movement of the ceiling 350. The height of the ceiling 350 changes from 140 cm to 210 cm. The volume of the interior I4 increases.

[0334] After 120 days have passed since the sowing date, the height of the plant P will be approximately 210 cm. Therefore, the structure 300 and the plant P will be in the form of the structure 300 and the plant P shown in FIG.

[0335] On the day 120 days after the sowing date, the space specifying unit 3612 specifies space information that associates the day (date) 120 days after the sowing date with "none" (necessary space N) (step S76). The receiving unit 3613 receives the space information and records it in the storage unit 3615.

[0336] On the day 120 days after the sowing date, the operation identification unit 3614 identifies operation information by associating the day 120 days after the sowing date with the fact that the ceiling 350 is not operating (step S77).

[0337] On the day when 120 days have passed since the sowing date, the structure control unit 362 controls the structure 300 so that the structure 300 does not operate (step S78). The height of the ceiling 350 remains at 210 cm.

[0338] On the day 120 days after the sowing date (harvest date), the structure control unit 362 moves the ceiling 350 in the Y direction and the movable plate 3113 in the X direction to realize the structure 300 shown in Figure 50 (step S79). A person or a device harvests the plants P in the interior I4.

[0339] On the day 120 days after the sowing date, after the harvesting work is completed, the structure control unit 362 moves the ceiling 350 in the negative Y direction and the movable plate 3113 in the negative X direction to realize the structure 300 shown in Fig. 65 (step S80). Since it is just after the harvesting, there are no plants P in the interior I4.

[0340] (4) Features (4-1) The information processing device 361 further includes a growth identification unit 3611 that identifies growth information based on type information indicating the type of plant P and environmental information indicating elements of at least one of the physical environment and the chemical environment in the interior I4 that affect the growth of the plant P. The space identification unit 3612 of the information processing device 361 identifies space information based on the growth information identified by the growth identification unit 3611.

[0341] Plant growth is affected by the type of plant and the environmental factors that affect plant growth, which in turn affect the volume that a plant requires.

[0342] The information processing device 361 can identify growth information based on the type information and the environmental information, and can identify spatial information with high accuracy. Therefore, the information processing device 361 can achieve energy savings in cultivating the plant P, and can reduce the cost of cultivating the plant P.

[0343] (4-2) The information processing device 361 includes environmental information indicating at least any of the temperature of the interior I4, the humidity of the interior I4, the illuminance of light in the interior I4, the time for which light is shone on the interior I4, the components of the air in the interior I4, the amount of water given to the plant P, the amount of fertilizer given to the plant P, the components of the fertilizer given to the plant P, the components of the soil S in which the plant P is planted, and the components of the nutrient solution in which the plant P is immersed.

[0344] Therefore, the information processing device 361 can identify the spatial information with high accuracy. Therefore, the information processing device 361 can achieve energy saving for the cultivation of the plant P, and can reduce the cost for the cultivation of the plant P.

[0345] (5) Modifications A modification of the third embodiment will be described, focusing on the differences from the third embodiment, and omitting the description of the similarities to the third embodiment.

[0346] (5-1) Modification 3A The structure 300 may be provided inside the plant factory 20 instead of inside the greenhouse 10. FIG. 72 is a schematic diagram showing the overall configuration of the structure system 3 according to Modification 3A. The racks R1 and R2 are provided inside I4 of the structure 300. The structure and function of the racks R1 and R2 are the same as those of Modification 1B of the first embodiment. In Modification 3A, the height is the distance in the Y direction from the ground F, except where it is described as a relative height.

[0347] <Fourth Embodiment> (1) Overall Configuration The overall configuration of the structure system 4 according to the fourth embodiment will be described. Below, similarities between the third and fourth embodiments will be omitted, and differences between the third and fourth embodiments will be mainly described. In the fourth embodiment, as in the third embodiment, front means the negative Z direction, rear means the Z direction, left means the negative X direction, right means the X direction, down means the negative Y direction, and up means the Y direction. Height is the distance in the Y direction from the soil S.

[0348] 73 is a schematic diagram showing the overall configuration of a structure system 4 according to the fourth embodiment. The structure system 4 mainly includes a greenhouse 10, an air conditioner 11, and a control device 46. The greenhouse 10 and the air conditioner 11 are the same as those in the third embodiment, and therefore description thereof will be omitted.

[0349] The control device 46 mainly controls the structure 300 and the air conditioner 11. The control device 46 is connected to the structure 300 and the air conditioner 11 by wire or wirelessly. Details of the control device 46 will be described later. The structure 300 is the same as in the third embodiment, so its description will be omitted.

[0350] (2) Detailed Configuration The detailed configuration of the control device 46 will be described. Fig. 74 is a functional block diagram of the control device 46. The control device 46 mainly includes an information processing device 461, a structure control unit 362, and an air conditioning control unit 363. The structure control unit 362 and the air conditioning control unit 363 are the same as those in the third embodiment, and therefore description thereof will be omitted.

[0351] (2-1) Information Processing Device The information processing device 461 mainly includes a learning unit 4610, a growth identification unit 4611, a space identification unit 3612, a reception unit 3613, an action identification unit 3614, and a storage unit 4615. The space identification unit 3612, the reception unit 3613, and the action identification unit 3614 are the same as those in the third embodiment, and therefore description thereof will be omitted.

[0352] (2-1-1) Learning Unit The learning unit 4610 learns by associating environmental information with growth information for each type of plant P, and generates a trained model for each type of plant P. In other words, the learning unit 4610 learns for each type of plant P, using the environmental information as an explanatory variable E and the growth information as a target variable R, and generates a trained model for each type of plant P. The learning unit 4610 records the generated trained model in association with the type of plant P in the storage unit 4615. Note that learning may include not only generating a trained model based on the training data L, but also calculating the accuracy of the trained model based on the test data T.

[0353] The training data L and the test data T are input to the control device 46 by a user or an external device (not shown). Alternatively, the training data L and the test data T may be input to the control device 46 from outside via a network by real-time processing or batch processing.

[0354] An example of the processing of the learning unit 4610 will be described. The learning unit 4610 reads the training data L and identifies the explanatory variables E and the response variable R. The learning unit 4610 generates a trained model by associating the explanatory variables E and the response variable R using a training method. Examples of training methods include, but are not limited to, multiple regression analysis, linear regression analysis, logistic regression analysis, and neural networks (Dropout, stochastic gradient descent (SGD), mini-batch gradient descent (Adam), backpropagation (BP), AdaDelta, AdaGrad, RMSprop, MomentumSGD, etc.). The learning unit 4610 associates the generated trained model with the type of plant P and records them in the storage unit 4615. Note that the learning unit 4610 may test the trained model based on test data T and calculate the accuracy of the trained model.

[0355] 75 is a diagram showing explanatory variable E, objective variable R, learning data L, and test data T. A specific example of the processing of the learning unit 4610 will be described based on the explanatory variable E and objective variable R, learning data L, and test data T in FIG. 75. Suppose the variety (major category) of plant P is cherry tomato, and the variety (minor category) of plant P is mini carol.

[0356] The explanatory variables E are the temperature of the interior I4, the humidity of the interior I4, and the illuminance of the interior I4. The dependent variable R is the period and the change in height of the plant P. The number of combinations of the explanatory variables E and the dependent variable R in FIG. 75 is 11, but is not limited to this. Eight combinations of the explanatory variables E and the dependent variable R are used as the training data L. Three combinations of the explanatory variables E and the dependent variable R are used as the test data T.

[0357] The learning unit 4610 reads a combination (learning data L) of eight explanatory variables E and a response variable R. The learning unit 4610 associates the explanatory variables E with the response variable R and performs learning using a neural network to generate a trained model. The learning unit 4610 associates the generated trained model with cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P) and records them in the memory unit 4615. The learning unit 4610 then inputs the explanatory variables E of the test data T into the trained model stored in the memory unit 4615. The learning unit 4610 compares the output of the trained model with the response variable R of the test data T to calculate the accuracy of the trained model.

[0358] The learning unit 4610 may use type information in addition to the environmental information as the explanatory variable E. For example, the learning unit 4610 may use a numerical value corresponding to the type of plant P (a numerical value that is set in advance corresponding to the type of plant P) as the explanatory variable E in addition to the environmental information.

[0359] (2-1-2) Growth Identification Unit The growth identification unit 4611 identifies growth information from the growth information output by inputting environmental information for each type of plant P into the trained model generated by the learning unit 4610. The growth identification unit 4611 records the identified growth information in the storage unit 4615.

[0360] An example of processing by the growth identification unit 4611 will be described. The growth identification unit 4611 reads type information stored in the storage unit 4615 and identifies the type of plant P. The growth identification unit 4611 identifies a trained model associated with the identified type of plant P from among the trained models stored in the storage unit 4615. The growth identification unit 4611 reads environmental information stored in the storage unit 4615 and inputs it to the identified trained model. The growth identification unit 4611 identifies the growth information output by the trained model as growth information.

[0361] A specific example of the processing of the growth identification unit 4611 when the type information is the type information in Fig. 52 and the environmental information is the environmental information in Fig. 53 will be described. The growth identification unit 4611 reads the type information in Fig. 52 and identifies cherry tomato (the variety (major category) of plant P) and mini carol (the variety (minor category) of plant P). Of the trained models stored in the storage unit 4615, the growth identification unit 4611 identifies a trained model associated with cherry tomato (the variety (major category) of plant P) and mini carol (the variety (minor category) of plant P).

[0362] The growth identification unit 4611 reads the environmental information in FIG. 53 and inputs 23°C (temperature of interior I4) and 75% (humidity of interior I4) into the identified trained model. Assume that the trained model outputs the growth information in FIG. 57. The growth identification unit 4611 identifies the growth information in FIG. 57 output by the trained model as growth information. The growth identification unit 4611 records the identified growth information in the storage unit 4615.

[0363] (2-1-3) Storage Unit The storage unit 4615 stores the trained model generated by the learning unit 4610. The storage unit 4615 also stores the growth information identified by the growth identification unit 4611. The storage unit 4615 also stores the spatial information received by the reception unit 3613. In addition, the storage unit 4615 stores the motion information identified by the motion identification unit 3614. The storage unit 4615 stores type information and environmental information. Examples of the storage unit 4615 include an HDD and an SSD.

[0364] (3) Operation The operation of the structure system 4 from the sowing date to the harvest date will be described. Assume that the learning data L and test data T in FIG. 75 are prepared in advance for cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P). Assume that the type information in FIG. 52 and the environmental information in FIG. 53 are pre-recorded in the memory unit 4615. Assume that the structure control cycle is one day. Assume that the harvest date is 120 days after the sowing date. Assume that the air conditioning control unit 363 controls the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior I4 is suitable for growing the plant P.

[0365] Figure 76 is a flowchart showing the operation of the structure system 4. Before the sowing work, the learning unit 4610 reads the training data L in Figure 75 and generates a trained model. Before the sowing work, the learning unit 4610 associates the generated trained model with cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P), and records the association in the memory unit 4615 (step S81).

[0366] On the sowing day, the structure control unit 362 moves the ceiling 350 in the Y direction and moves the movable plate 3113 in the X direction to realize the structure 300 shown in Fig. 50 (step S82). A person or a device performs the work of sowing plants P in the interior I4.

[0367] On the sowing day, after the sowing work is completed, the structure control unit 362 moves the ceiling 350 in the negative Y direction and the movable plate 3113 in the negative X direction to realize the state of the structure 300 in Fig. 65 (step S83). The height of the ceiling 350 is 140 cm.

[0368] On the sowing date, the growth identification unit 4611 identifies the trained models associated with cherry tomato (a variety (major category) of plant P) and mini carol (a variety (minor category) of plant P) from among the trained models stored in the memory unit 4615. The growth identification unit 4611 reads the identified trained model and inputs 23°C (temperature of interior I4) and 75% (humidity of interior I4) into the identified trained model. Assume that the trained model outputs the growth information of Figure 57. The growth identification unit 4611 identifies the growth information of Figure 57 as growth information (step S84). The growth identification unit 4611 records the identified growth information in the memory unit 4615.

[0369] The space identification unit 3612 identifies the required space N based on the growth information in FIG. 57 and identifies space information (step S85). The reception unit 3613 receives the space information and records it in the storage unit 4615. The action identification unit 3614 associates the fact that the ceiling 350 will not move with the date and identifies action information (step S86). The action identification unit 3614 records the identified action information in the storage unit 4615. The structure control unit 362 reads the action information and controls the structure 300 so that the structure 300 does not move (step S87).

[0370] According to the growth information in FIG. 57 , the daily change in height of the plant P is 1.6 cm. The height of the ceiling 350 on the sowing date is 140 cm. Therefore, the structure system 4 repeats the operations from step S85 to step S87 from the sowing date until 86 days after the sowing date (loop 1). The ceiling 350 does not operate from the sowing date until 86 days after the sowing date. The height of the ceiling 350 remains at 140 cm until 86 days after the sowing date.

[0371] From the day 87 days after the sowing date to the day 119 days after the sowing date, the space identification unit 3612 identifies the required space N based on the growth information in FIG. 57 and identifies space information (step S88). The receiving unit 3613 receives the space information and records it in the storage unit 4615. The motion identification unit 3614 associates the fact that the ceiling 350 will move in the Y direction with the date and identifies motion information (step S89). The motion identification unit 3614 records the identified motion information in the storage unit 4615. The structure control unit 362 reads the motion information and controls the structure 300 so that the ceiling 350 moves in the Y direction (step S90).

[0372] The height of the upper surface of the required space N on the day 87 days after the sowing date is 140.8 cm. The height of the ceiling 350 on the day 87 days after the sowing date is 140 cm. Therefore, the structure system 4 repeats the operations from step S88 to step S90 from the day 87 days after the sowing date until the day 119 days after the sowing date (loop 2). On the day 87 days after the sowing date, the ceiling 350 moves 0.8 cm in the Y direction. From the day 88 days after the sowing date until the day 119 days after the sowing date, the ceiling 350 moves 1.6 cm in the Y direction every day. On the day 119 days after the sowing date, the height of the ceiling 350 changes to 192 cm.

[0373] On the harvest day, the space identification unit 3612 identifies that the required space N does not exist and identifies space information. The reception unit 3613 receives the space information and records it in the storage unit 4615. The action identification unit 3614 associates the fact that the ceiling 350 will not move with the date and identifies action information. The action identification unit 3614 records the identified action information in the storage unit 4615. The structure control unit 362 reads the action information and controls the structure 300 so that the ceiling 350 will not move (step S91).

[0374] On the harvest day, the structure control unit 362 moves the ceiling 350 in the Y direction and the movable plate 3113 in the X direction to realize the structure 300 shown in Fig. 50 (step S92). A person or a device harvests the plants P in the interior I4.

[0375] On the harvest day, after the harvesting work is completed, the structure control unit 362 moves the ceiling 350 in the negative Y direction and moves the movable plate 3113 in the negative X direction to realize the structure 300 configuration shown in Figure 65 (step S93).

[0376] (4) Features (4-1) The information processing device 461 identifies growth information based on the growth information output by inputting environmental information for each type of plant P into a learned model generated by the growth identification unit 4611 through learning in which environmental information and growth information are associated for each type of plant P.

[0377] Plants grow under the influence of scientific factors (such as environmental factors). The environmental factors for each plant type are correlated with plant growth. Therefore, a trained model can be generated by associating the environmental factors for each plant type with plant growth.

[0378] The information processing device 461 identifies the growth information using a trained model generated by learning by associating environmental information with growth information for each type of plant P. As a result, the information processing device 461 can achieve energy savings in cultivating the plant P and reduce the cost of cultivating the plant P.

[0379] (4-2) The information processing device 461 further includes a learning unit 4610 that learns by associating environmental information with growth information for each type of plant P and generates a trained model for each type of plant P. The growth identification unit 4611 of the information processing device 461 inputs environmental information for each type of plant P into the trained model generated by the learning unit 4610 and identifies the growth information from the output growth information.

[0380] Therefore, the information processing device 461 can achieve energy savings in cultivating the plant P, and can reduce the cost of cultivating the plant P.

[0381] (5) Modifications A modification of the fourth embodiment will be described, focusing on the differences from the fourth embodiment, and omitting the description of the similarities to the fourth embodiment.

[0382] (5-1) Modification 4A The information processing device 461 may not include the learning unit 4610. In this case, information associating the trained model with the type of plant P is input to the control device 46 by a user or an external device (not shown). Alternatively, information associating the trained model with the type of plant P may be input to the control device 46 from outside via a network by real-time processing or batch processing.

[0383] (5-2) Modification 4B (5-2-1) Configuration The information processing device 461 may further include an update unit (not shown). The update unit updates the trained model generated by the learning unit 4610 based on information in which environmental information and growth information are associated for each type of plant P. The update unit records the updated trained model in the storage unit 4615. This performs machine learning on the trained model.

[0384] When a trained model is generated using a small amount of training data, the accuracy of the trained model may be low. Also, it may be difficult to prepare all the training data corresponding to various types of plants and various environments.

[0385] The information processing device 461 updates the trained model based on information in which environmental information and growth information are associated for each type of plant P. The information processing device 461 can improve the accuracy of the trained model. As a result, the information processing device 461 can achieve energy savings in cultivating the plant P and reduce the cost of cultivating the plant P.

[0386] (5-3) Modification 4C The control device 46 may control the structure 300 inside the plant factory 20 and the racks R1 and R2 provided in the structure 300 instead of the structure 300 inside the greenhouse 10. The structure and function of the racks R1 and R2 are the same as those in Modification 1B of the first embodiment. In Modification 4C, the height is the distance in the Y direction from the ground F, except where it is described as a relative height.

[0387] Fifth Embodiment (1) Overall Configuration The overall configuration of the structure system 5 according to the fifth embodiment will be described. Below, similarities between the third and fifth embodiments will be omitted, and differences between the third and fifth embodiments will be mainly described. In the fifth embodiment, as in the third and fourth embodiments, front means the negative Z direction, rear means the Z direction, left means the negative X direction, right means the X direction, down means the negative Y direction, and up means the Y direction. Height is the distance in the Y direction from the soil S.

[0388] 77 is a schematic diagram showing the overall configuration of a structure system 5 according to the fifth embodiment. The structure system 5 mainly includes a greenhouse 10, an air conditioner 11, a control device 56, and a sensor 59. The greenhouse 10 and the air conditioner 11 are the same as those in the third embodiment, and therefore will not be described here.

[0389] (1-1) Control Device The control device 56 mainly controls the structure 300 and the air conditioner 11. The control device 56 is connected to the structure 300 and the air conditioner 11 by wire or wirelessly. Details of the control device 56 will be described later. The structure 300 is the same as in the third embodiment, so its description will be omitted.

[0390] (1-2) Sensor The sensor 59 detects the presence of the plant P within a predetermined distance below (in the negative Y direction) the ceiling 350 and generates detection information. The detection information is information indicating the presence of the plant P within a predetermined distance below the ceiling 350. The sensor 59 transmits the generated detection information to the control device 56. Examples of the sensor 59 include, but are not limited to, an infrared sensor, an image sensor, a heat sensor, and an electromagnetic sensor.

[0391] The sensor 59 is provided in the interior 14. The sensor 59 may be provided in a location other than the interior 14 where the sensor 59 can detect the presence of the plant P within a predetermined distance below the ceiling 350. Examples of the predetermined distance include, but are not limited to, 3 cm to 10 cm.

[0392] (2) Detailed Configuration The detailed configuration of the control device 56 will be described. Fig. 78 is a functional block diagram of the control device 56. The control device 56 mainly includes a receiving unit 560, a structure control unit 562, and an air conditioning control unit 363. The air conditioning control unit 363 is the same as in the third embodiment, and therefore description thereof will be omitted.

[0393] (2-1) Receiving Unit The receiving unit 560 receives detection information from the sensor 59.

[0394] (2-2) Structure Control Unit When the receiving unit 560 receives detection information, the structure control unit 562 controls the structure 300 to ensure the required space N. An example of the required space N is a space in which the height of the bottom surface of the required space N is the current height of the ceiling 350, and the height of the top surface of the required space N is the sum of the current height of the ceiling 350 and a preset height (hereinafter referred to as the set height). Examples of the set height include, but are not limited to, heights from 1 cm to 30 cm.

[0395] A description will be given of an example of the processing of the structure control unit 562. When the receiving unit 560 receives detection information, the structure control unit 562 moves the ceiling 350 in the Y direction by 20 cm (set height).

[0396] The structure control unit 562 does not have a structure control cycle, unlike the structure control unit 162 (first embodiment and second embodiment) and the structure control unit 362 (third embodiment and fourth embodiment). The structure control unit 562 controls the structure 300 using the reception of detection information by the receiving unit 560 as a trigger.

[0397] The structure control unit 562 controls the structure 300 to realize the state of the structure 300 when agricultural work is being performed. Before the agricultural work begins, the structure control unit 562 moves the ceiling 350 in the Y direction and moves the movable plate 3113 in the X direction to realize the state of the structure 300 shown in FIG. 50 . After the agricultural work is completed, the structure control unit 562 moves the ceiling 350 in the negative Y direction and moves the movable plate 3113 in the negative X direction to realize the state of the structure 300 before the agricultural work.

[0398] (3) Operation The operation of the structure system 5 from the sowing date to the harvest date will be described. The predetermined distance to the sensor 59 is assumed to be 10 cm. The set height is assumed to be 10 cm. The air conditioning control unit 363 is assumed to control the air conditioner 11 so that the environment (temperature, humidity, etc.) of the interior 14 becomes an environment suitable for growing the plants P.

[0399] Figure 79 is a flowchart showing the operation of the structure system 5. On the sowing day, the structure control unit 562 moves the ceiling 350 in the Y direction and moves the movable plate 3113 in the X direction to realize the configuration of the structure 300 in Figure 50 (step S101). A person or a device performs the work of sowing plants P in the interior I4.

[0400] On the sowing day, after the sowing work is completed, the structure control unit 562 moves the ceiling 350 in the negative Y direction and moves the movable plate 3113 in the negative X direction to realize the state of the structure 300 in Fig. 65 (step S102). The height of the ceiling 350 is 140 cm.

[0401] If the sensor 59 detects the presence of a plant P within 10 cm below the ceiling 350 from the sowing date to the harvest date (step S103: YES), the sensor 59 transmits the detection information to the control device 56. The receiving unit 560 receives the detection information (step S104). The structure control unit 562 moves the ceiling 350 10 cm in the Y direction (step S105).

[0402] If the sensor 59 does not detect the presence of plant P within 10 cm below the ceiling 350 from the sowing date to the harvest date (step S103: NO), the sensor 59 does not transmit the detection information to the control device 56, and the structure control unit 562 does not operate the ceiling 350.

[0403] If the harvest date or the height of the ceiling 350 has not reached 210 cm (the maximum height of the ceiling 350) (step S106: NO), the operation of step S103 is repeated. On the other hand, if the harvest date or the height of the ceiling 350 has reached 210 cm (step S106: YES), the repetition of the operation of step S103 is terminated.

[0404] On the harvest day, the structure control unit 562 moves the ceiling 350 in the Y direction and the movable plate 3113 in the X direction to realize the structure 300 shown in Fig. 50 (step S107). A person or a device harvests the plants P in the interior I4.

[0405] On the harvest day, after the harvesting work is completed, the structure control unit 562 moves the ceiling 350 in the negative Y direction and moves the movable plate 3113 in the negative X direction to realize the structure 300 in the state shown in Figure 65 (step S108).

[0406] (4) Features The control device 56 further includes a receiving unit 560 that receives detection information indicating the presence of a plant P within a predetermined distance from the ceiling 350 of the structure 300 from a sensor 59 that detects the presence of a plant P within a predetermined distance from the ceiling 350 of the structure 300. When the receiving unit 560 receives the detection information, the structure control unit 562 of the control device 56 controls the structure 300 to ensure the required space N.

[0407] It may be difficult to predict in advance the change in height of a plant due to its growth. When the control device 56 receives detection information indicating the presence of a plant P within a predetermined distance from the ceiling 350, it controls the structure 300 to ensure the required space N. The control device 56 can control the structure 300 to ensure the required space N using the sensor 59 without preparing growth information in advance or requiring complex processing. Therefore, the control device 56 can achieve energy savings in cultivating the plant P and reduce the cost of cultivating the plant P.

[0408] (5) Modifications The following description of modifications of the fifth embodiment will focus on the differences from the fifth embodiment, omitting the description of the similarities to the fifth embodiment.

[0409] (5-1) Modification 5A The control device 56 may control the structure 300 inside the plant factory 20 instead of the structure 300 inside the greenhouse 10, and the racks R1 and R2 provided in the structure 300. The structure and function of the racks R1 and R2 are the same as those in Modification 1B of the first embodiment. In Modification 5A, the height is the distance in the Y direction from the ground F, except where it is described as a relative height.

[0410] The sensor 59 detects the presence of a plant P within a predetermined distance below the movable platform 182, the presence of a plant P within a predetermined distance below the movable platform 183, and the presence of a plant P within a predetermined distance below the ceiling 350. The detection information is information indicating the presence of a plant P within a predetermined distance below the movable platform 182, the presence of a plant P within a predetermined distance below the movable platform 183, and the presence of a plant P within a predetermined distance below the ceiling 350. When the receiving unit 560 receives the detection information, the structure control unit 562 moves the movable platform 182, the movable platform 183, and the ceiling 350 in the Y direction by a set height.
