Summary of the Invention

Problems to be Solved by the Invention

[0005] In such a cultivation facility, it is desired to improve the efficiency of each process performed until the plants are shipped, such as the process of sowing plant seeds and the process of supplying water to the sown seeds, and to achieve unmanned operation for quality improvement in terms of hygiene.

[0006] Therefore, the purpose of the present technology is to realize the improvement of work efficiency and unmanned operation in each process.

Means for Solving the Problems

[0007] The seeding apparatus according to this technology comprises a container on which multiple seeds can be placed, a vibration mechanism for vibrating the container, an imaging device capable of imaging the seeds placed in the container, a moving mechanism for moving seeds from the container to a pot containing a growing medium for sowing seeds, and an information processing device that performs the following: a process for detecting seeds to be moved by the moving mechanism based on image data captured from the imaging device, a process for moving the detected seeds to the pot using the moving mechanism if the seeds to be moved can be detected, and a process for vibrating the container using the vibration mechanism if the seeds to be moved cannot be detected.

[0008] This causes the container to vibrate via the vibration mechanism until the seeds to be moved can be detected. As the container vibrates, the seeds placed on it also vibrate, causing each seed to move away from the others.

[0009] The water supply device according to this technology comprises a pressing mechanism capable of pressing a culture medium attached to a pot, with a water supply hole formed on the end surface that contacts the culture medium when pressing, and an information processing device that performs the process of causing the pressing mechanism to press the culture medium, and the process of supplying water from the water supply hole while the culture medium is pressed.

[0010] As a result, when the pressure is released, the culture medium elastically deforms due to its restorative force, and water is absorbed into the culture medium in accordance with this elastic deformation.

[0011] The first program relating to this technology causes an information processing device to perform the following processes based on captured image data from an imaging device: detecting a seed to be moved by a moving mechanism from among a plurality of seeds placed in a container; moving the detected seed to a culture medium using the moving mechanism if the seed to be moved is detected; and vibrating the container using a vibration mechanism if the seed to be moved cannot be detected.

[0012] The second program relating to this technology causes an information processing device to perform the following steps: pressing the culture medium stored in a pot with a pressing mechanism, and supplying water through a water supply hole formed on the end face of the pressing mechanism that contacts the culture medium while the culture medium is pressed. [Effects of the Invention]

[0013] This technology makes it possible to improve the efficiency of work and enhance hygiene quality in each stage of cultivation equipment. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present technology will be described with reference to FIGS. 1 to 16. Note that the configurations shown in the drawings referred to in the description are those obtained by extracting the main parts necessary for realizing the present embodiment and the configurations around them. In addition, each configuration including the plants shown in the drawings is schematically shown, and the relationship between the thickness and the planar dimensions, ratios, etc. in each configuration are merely examples. Therefore, within the scope not departing from the technical idea of the present technology, for each configuration, design changes and substitutions with equivalent configurations are possible.

[0016] Referring to FIG. 1, the outline of the plant production system 100 will be described. Examples of the plant 6 produced in the plant production system 100 include leafy vegetables mainly having leaves and stems as edible parts, such as lettuce, and include spinach, komatsuna, and chingensai. In addition, the plant 6 here is not limited to leafy vegetables, and may include, for example, cruciferous vegetables mainly having flower buds as edible parts, such as rape, broccoli, and cauliflower, and fruit vegetables having fruits or seeds as edible parts, such as eggplant, pepper, and tomato.

[0017] The plant production system 100 includes cultivation equipment 101 for cultivating and harvesting a plurality of plants 6, and shipping equipment 102 for shipping the harvested plants 6. The cultivation equipment 101 and the shipping equipment 102 are provided, for example, inside a plant factory building.

[0018] The cultivation facility 101 includes a sowing area 111, a sorting area 112, a seedling raising area 113, a transplanting area 114, a growth area 115, a harvesting area 116, and a washing area 117.

[0019] In the sowing area 111, the seeds 7 of the plants 6 to be cultivated are sorted and sown. In the sowing area 111, seeds 7 that are expected to have poor germination, for example, are removed. The remaining seeds 7 to be sown are sown into pots 3 (see Figure 2), which are containers fitted with the growing medium 2. The sown pots 3 are placed in groups on a transport panel 4 and transported to the next process.

[0020] When the seeds 7 sown in the culture medium 2 within the pot 3 germinate, the plants 6 are transported to the sorting area 112 by the transport panel 4.

[0021] In the sorting area 112, plants 6 with poor germination or other defects are removed. The remaining plants 6 are designated for seedling cultivation and are transported to the seedling cultivation area 113 for cultivation. The cultivated plants 6 are then transported to the transplanting area 114.

[0022] In the planting area 114, the pots 3 of plants 6, which have been grown in the seedling transport panel 4, are moved to the growth transport panel 5. At this time, pots 3 of plants 6 that are not growing well are removed. In addition, to maintain an appropriate distance between each plant 6 as it grows, the transport panel 5 ensures a wide spacing between each plant 6. The number of times the plants 6 are rearranged to other transport panels for growth can be set according to the type of plant 6 being grown and the growth method.

[0023] The transport panel 5 on which the pot 3 is placed is transported to the growth area 115, where the plant 6 is grown. Once the plant 6 has grown to a harvestable stage in the growth area 115, the transport panel 5 is transported to the harvest area 116.

[0024] In the harvesting area 116, the grown plants 6 are harvested. In the harvesting area 116, the plants 6 are harvested by separating them from the pots 3, for example by cutting the base of the stem. The harvested plants 6 are then transported to the shipping facility 102.

[0025] In the washing area 117, various transport panels 4, 5 and cultivation tools such as pots 3 used for cultivating plants 6 are washed, sterilized, and dried. After washing, the cultivation tools are transported to their respective areas and reused for cultivating plants 6.

[0026] The shipping equipment 102 includes a lower leaf processing area 121, a weighing area 122, a packaging area 123, a boxing area 124, and a loading area 125.

[0027] The plants 6 harvested in the harvesting area 116 of the cultivation facility 101 are transported to the lower leaf processing area 121. In the lower leaf processing area 121, lower leaf processing is performed to remove parts of the plants 6 that are not needed for shipment. The parts targeted for lower leaf processing here include parts of the plants 6 that are unsuitable for consumption, such as parts that have turned black due to factors such as decay. Note that this lower leaf processing may also be performed in the harvesting area 116 of the cultivation facility 101.

[0028] The trimmed plants 6 are sorted according to their product specifications based on their weight measured in the weighing area 122, and then packaged with film or the like in the packaging area 123. The packaged plants 6 are transported to the boxing area 124, inspected by a metal detector, and then packed into pre-formed boxes. The boxes containing the plants 6 are stacked on pallets in the loading area 125 and shipped in a refrigerated state.

[0029] Furthermore, all or part of each area in the cultivation facility 101 may be provided in the shipping facility 102, and all or part of each area in the shipping facility 102 may be provided in the cultivation facility 101. Also, the configurations provided in each area of ​​each facility are merely classifications for convenience, and one of the above-mentioned areas may include all or part of the configurations included in the other areas.

[0030] Furthermore, either the cultivation facility 101 or the shipping facility 102 may be located in different factories. In addition, parts of each area of ​​the cultivation facility 101 and the shipping facility 102 may be located in different factories. In other words, even if parts of each facility and its areas are located in different places, the plant production system 100 is constructed based on the functions of each facility.

[0031] Next, referring to Figure 2, the structures of the growing medium 2, pots 3, and transport panels 4 and 5 used in the cultivation equipment 101 will be described. The growing medium 2, pots 3, and transport panels 4 and 5 are included in the plant production system 100.

[0032] The culture medium 2 is formed, for example, in a cubic shape, from a resin molded product such as urethane, a mineral-derived material such as rock wool, or an organic material such as peat moss. A depression is formed on one side of the cubic shape, which serves as a sowing hole 2a for placing the seeds 7. The culture medium 2 is water-absorbent and formed in an elastic, sponge-like manner. Note that the cubic shape of the culture medium 2 is just one example; it can be made into various shapes such as a cylinder.

[0033] Pot 3 is used as a container for holding the growing medium 2 in order to handle the plants 6 being cultivated and to stabilize the position of the growing medium 2. Pot 3 opens upwards, forming a storage space 3a in which the growing medium 2 can be stored. The storage space 3a is shaped to accommodate the cubic shape of the growing medium 2.

[0034] After the culture medium 2 is placed in the pot 3, the pot 3 is loaded onto the transport panel 4, for example, after seeds 7 have been sown in the sowing hole 2a. The transport panel 4 is provided with multiple pot placement holes 4a. When the pot 3 is inserted into these pot placement holes 4a from the bottom side, the flange 3c provided on the rim of the pot 3 is locked to the upper surface of the transport panel 4. The flange 3c has a rectangular outer edge, but it can be formed into various shapes such as circles or polygons.

[0035] This locking mechanism ensures that the pots 3 are stably placed on the transport panel 4. Furthermore, by placing detachable pots 3 in each of the multiple pot placement holes 4a, transport within each area of ​​the cultivation facility 101 becomes more efficient.

[0036] Although not shown in the diagram, the transport panel 5 (see Figure 1) also has pot placement holes 5a formed therein. However, the pot placement holes 5a of the transport panel 5 are spaced wider apart than those of the transport panel 4, and wider apart than the spacing of the pot placement holes 4a.

[0037] Next, with reference to Figure 3, the components included in the cultivation equipment 101 will be described. The cultivation equipment 101 includes, for example, an imaging device 10, a work unit 11, an information processing device 12, and a database 13.

[0038] In the cultivation facility 101, the operation of the work units 11 provided in each area is controlled by the information processing device 12, allowing various tasks on the plants 6 to be performed automatically without human intervention. The information processing device 12 can also control the operation of the imaging device 10.

[0039] The imaging device 10 performs remote sensing of plants 6 in each area of ​​the cultivation facility 101. The image data obtained by the imaging device 10 is sent to the information processing device 12.

[0040] The imaging device 10 includes an imaging unit, a signal processing unit, and an image processing control unit. The imaging unit includes an imaging lens system, an exposure unit, a filter, and an image sensor. The image sensor detects the light that has passed through the filter using its sensing element and outputs an image signal corresponding to the amount of light to the signal processing unit.

[0041] The signal processing unit processes the captured image signal output from the image sensor of the imaging unit, performing AGC (Automatic Gain Control) processing, A / D (Analog / Digital) conversion processing, etc., to convert it into digital data. It then performs various necessary signal processing and outputs it to the imaging control unit as image data of the target to be captured. The imaging control unit stores the image data supplied sequentially from the signal processing unit in a storage unit (not shown), for example, so that it can be transmitted to the information processing device 12.

[0042] The imaging control unit is configured, for example, by a microcomputer, and controls the overall operation of the imaging device 10, including imaging, image data storage, and communication.

[0043] The imaging device 10 is provided, for example, in the sowing area 111. The imaging device 10 may be provided in each area of ​​the cultivation equipment 101, or one imaging device 10 may be configured to image multiple areas. Furthermore, multiple imaging devices 10 may be provided in each area. Also, the imaging device 10 may be included as part of the work unit 11.

[0044] The work units 11 are provided in each area of ​​the cultivation facility 101 and are equipped with various configurations necessary for the work in each area. Multiple work units 11 may be provided in each area. The work units 11 operate based on control signals from the information processing device 12 and perform various tasks required in each area. For example, a work unit 11 is provided in the sowing area 111. Details of the work unit 11 in the sowing area 111 will be described later.

[0045] The hardware configuration of the information processing device 12 will now be described. The information processing device 12 includes a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory), each of which is interconnected via a bus.

[0046] The CPU executes various processes according to programs stored in ROM or loaded into RAM. RAM also stores data necessary for the CPU to perform these processes.

[0047] The CPU performs processing operations based on various programs, thereby executing the necessary information processing and communication in the information processing device 12. For example, the functions of the information processing device 12 may be incorporated into electronic devices such as equipment management devices for the entire plant factory in the plant production system 100. Alternatively, the functions of the information processing device 12 may be incorporated into each electronic device, such as equipment management devices in each area. For example, the information processing device 12 may be included as part of the work unit 11 provided in each area. Furthermore, the functions of the information processing device 12 may be incorporated not only into equipment management devices in each area, but also into personal computers and mobile terminals.

[0048] The information processing device 12 is not limited to being composed of a single CPU, but may be configured with multiple CPUs in a system. These multiple CPUs may include CPUs available through cloud computing services.

[0049] The information processing device 12 includes a function to control the operation of the work unit 11 and the imaging device 10 based on, for example, image data obtained by the imaging device 10 and detection information from sensors provided on the work unit 11.

[0050] Each function of the information processing device 12 is a function realized by processing performed by, for example, the CPU included in the information processing device 12. Note that all or some of the processing of each configuration described below may be realized by hardware. Furthermore, when each function is realized by software, it is not necessary for each function to be realized by an independent program. A single program may execute the processing of multiple functions, or a single function may be realized through the cooperation of multiple program modules.

[0051] Database 13 records various data necessary for processing performed by the information processing device 12. For example, Database 13 records data for each type of plant 6, such as the size, shape, and color of seeds 7 suitable for sowing, the number of seeds 7 to sow in the sowing holes 2a of the culture medium 2, the appropriate sowing interval, and data related to measuring the amount of water supplied to the sown seeds 7. In addition, data related to measuring the amount of water supplied to the sown seeds 7 is recorded for each type of pot 3 and the type of culture medium 2 attached to it.

[0052] The database 13 may be built in a separate information processing device from the information processing device 12, or it may be built in the information processing device 12. The database 13 may be implemented in any form as long as it is accessible to the information processing device 12.

[0053] Next, with reference to Figure 4, the equipment provided in the seeding area 111 of the cultivation facility 101 will be described. The seeding area 111 is equipped with a pot conveying conveyor 22, a panel conveying conveyor 21, a culture medium supply device 23, a seeding device 24, a water supply device 25, and a pot moving device 26.

[0054] Multiple pots 3 are transported by a pot transport conveyor 22. The pot transport conveyor 22 is equipped with multiple placement units 22a on which the pots 3 are placed during transport. For example, pots 3 that have been washed in the washing area 117 are placed on their respective placement units 22a by a parts feeder (not shown).

[0055] The pot conveyor 22 moves the pots 3, for example, with direction F1 as the direction of travel. A culture medium supply device 23, a seeding device 24, a water supply device 25, and a pot moving device 26 are arranged in order to the side of the pot conveyor 22. The necessary operations are performed on the pots 3 as they are transported by the pot conveyor 22 by each of the above devices.

[0056] On the other side of the pot conveying conveyor 22, a panel conveying conveyor 21 is provided to run adjacent to and parallel to it. Multiple conveying panels 4 are conveyed by the panel conveying conveyor 21. For example, conveying panels 4 that have been washed in the washing area 117 are transported by the panel conveying conveyor 21. The panel conveying conveyor 21 moves the conveying panels 4 with, for example, direction F1 as the direction of travel.

[0057] The culture medium supply device 23 applies the culture medium 2 to the pots 3 that are being transported by the pot conveyor 22. The pots 3 with the culture medium 2 applied are then transported by the pot conveyor 22 to the position of the seeding device 24.

[0058] The seeding device 24 sows seeds 7 into the culture medium 2 of the transported pots 3. The pots 3 with seeds 7 sown in the culture medium 2 are transported by the pot transport conveyor 22 to the location of the watering device 25.

[0059] The water supply device 25 supplies moisture to the growing medium 2 of the transported pots 3. This moisture is necessary for the germination of the sown seeds 7. The pots 3, with moisture supplied to the growing medium 2, are transported by the pot transport conveyor 22 to the position of the pot moving device 26.

[0060] The pot transfer device 26 moves the pots 3, which are being transported by the pot transport conveyor 22, to the transport panels 4, which are being transported by the panel transport conveyor 21. As a result, the pots 3 are placed in each of the pot placement holes 4a of the transport panel 4. With this, the process in the sowing area 111 is completed.

[0061] Subsequently, when the seeds 7 sown in the culture medium 2 within the pots 3 germinate in the sowing area 111, the transport panel 4 on which the pots 3 are placed is transported to the sorting area 112 by the pot transport conveyor 22.

[0062] In addition, in the sowing area 111, the order of the water supply device 25 and the sowing device 24 may be reversed in direction F1. That is, after supplying water to the culture medium 2 in the pot 3 with the water supply device 25, the seeds 7 may be sown in the culture medium 2 with the sowing device 24. In this case, an additional step is added to supply water to hydrate the seeds 7 before or after they are sown in the culture medium 2.

[0063] Next, with reference to Figures 5 to 11, the seeding device 24 in the seeding area 111 will be described. As shown in Figures 5 and 6, the seeding device 24 is equipped with a seed placement mechanism 30 and a moving mechanism 40 as a work unit 11 (see Figure 3). The seeding device 24 also includes an imaging device 10 and an information processing device 12.

[0064] The seed placement mechanism 30 includes a slider 31, a feeder 32, a container 33, a vibration mechanism 34, a light-emitting mechanism 35, and a receiving tray 36.

[0065] The slider 31 guides the seeds 7 to the feeder 32. The slider 31 is open in the upward and longitudinal directions, and its cross-sectional shape in the direction perpendicular to the longitudinal direction is U-shaped. One end of the slider 31 in the longitudinal direction is open toward the storage hole 32a of the feeder 32, which will be described later. The slider 31 is also inclined so that its height decreases in the vertical direction as it approaches the storage hole 32a. Therefore, the seeds 7 supplied from the other end of the slider 31 in the longitudinal direction are guided toward the storage hole 32a.

[0066] The supply of seeds 7 to the slider 31 may be performed manually by an operator in the cultivation facility 101. In this case, the slider 31 extends to an area accessible to the operator. Alternatively, a device for automatically supplying seeds 7 to the slider 31 may be provided. In this case, the operation of the device may be controlled, for example, by the information processing device 12. This device may be included in the seeding device 24.

[0067] The feeder 32 has an internal space, and a storage hole 32a and a supply hole 32b are provided as openings to this internal space. The storage hole 32a is formed to open upward, and the seeds 7 carried by the slider 31 pass through the storage hole 32a and are stored in the internal space.

[0068] The supply hole 32b is formed to open to the side, and a guide plate 32c that protrudes laterally is provided at the lower rim of the opening. A portion of the seeds 7 stored in the internal space of the feeder 32 is supplied to the container 33 from the supply hole 32b via the guide plate 32c at a predetermined timing.

[0069] The container 33 is formed in a box shape with an opening at the top, and has a bottom surface 33a facing vertically and a plurality of side surfaces 33b protruding upward from each side of the bottom surface 33a. The bottom surface of the container 33 functions as a mounting surface 33d for placing a plurality of seeds 7 supplied from the feeder 32.

[0070] The seeds 7 placed on the mounting surface 33d are imaged by the imaging device 10 (see Figure 6). The image data obtained is supplied to the information processing device 12, and based on the image data, the seeds 7 to be moved to the pot 3 are detected.

[0071] A sorting hole 33c opening to the side is formed in one of the multiple side portions 33b. The sorting hole 33c is formed continuously with the mounting surface 33d. Note that the sorting hole 33c may be formed in multiple side portions 33b. Also, multiple supply holes 32b may be formed in a single side portion 33b.

[0072] As shown in Figure 6, among the seeds 7 supplied to the container 33, there may be seeds 7b that are unsuitable for germination due to defects or deformation. Although not shown, the placement surface 33d may also contain not only seeds 7 but also fine debris, powder, and other materials besides seeds 7. As shown in Figure 7, the sorting holes 33c function as holes for discharging such seeds 7b and fine debris. Therefore, the vertical width of the sorting holes 33c is formed to be greater than the longest width of the seeds 7b. Furthermore, to prevent suitable seeds 7 from being discharged, as shown in Figure 8, the vertical width of the sorting holes 33c is formed to be smaller than the shortest width of the suitable seeds 7.

[0073] Returning to Figure 6, a vibration mechanism 34 for vibrating the container 33 is provided at the bottom of the container 33. For example, the container 33 is vibrated by driving a vibration actuator included in the vibration mechanism 34 under the control of the information processing device 12.

[0074] Multiple seeds 7 supplied from the feeder 32 to the container 33 may accumulate in one place on the mounting surface 33d, as shown in Figure 9. In this case, it may not be possible to accurately detect each seed 7 from the image data obtained by the imaging device 10. Therefore, by vibrating the container 33 with the vibration mechanism 34, the seeds 7 can be dispersed and separated from each other, as shown in Figure 10. This improves the accuracy of detecting the seeds 7 from the image data obtained by the imaging device 10 through image analysis.

[0075] Furthermore, a light-emitting mechanism 35 is provided at the bottom of the bottom surface 33a of the container 33. The light-emitting mechanism 35 is capable of projecting light onto the bottom surface 33a. The light-emitting mechanism 35 consists of, for example, multiple LEDs (Light Emitting Diodes) provided on a substrate, and emits light based on, for example, the control of the information processing device 12.

[0076] The bottom surface 33a is translucent, allowing light from the light-emitting mechanism 35 to pass through. This illuminates the seeds 7 placed on the mounting surface 33d, improving the accuracy of detecting the seeds 7 from the image data obtained by the imaging device 10 through image analysis.

[0077] Returning to Figure 5, the receiving tray 36 is formed in a box shape with an opening at the top. The receiving tray 36 is located on the side of the container 33 where the sorting hole 33c is open. Seeds 7b and fine debris discharged from the sorting hole 33c are collected in the receiving tray 36.

[0078] The moving mechanism 40 is a mechanism for moving seeds 7 placed on a container 33 to a culture medium 2 in a pot 3, and is composed of an arm, a joint mechanism, an actuator, etc. The tip of the arm of the moving mechanism 40 is provided with a plurality of suction holes 41, and the seeds 7 can be moved by adsorption through air suction from each suction hole 41. The operation of the moving mechanism 40 is controlled by the information processing device 12. In addition to air suction, a chuck system or other method can also be used to move the seeds 7 in the moving mechanism 40.

[0079] The following describes the work process performed in the seeding device 24. For the operation, the feeder 32 (see Figure 5) is pre-filled with a large quantity of seeds 7 supplied from the slider 31. When the seeds 7 in the feeder 32 run low, seeds 7 are replenished from the slider 31. In addition, the mounting surface 33d of the container 33 is continuously imaged by the imaging device 10 (see Figure 6).

[0080] First, seeds 7 are supplied from the feeder 32 to the container 33 at a predetermined timing. Then, the container 33 is vibrated by the vibration mechanism 34 until the seeds 7 to be moved can be detected based on the image data of the mounting surface 33d obtained by the imaging device 10. For example, the container 33 is vibrated from a state where multiple seeds 7 are piled up on the mounting surface 33d as shown in Figure 9 until the seeds 7 on the mounting surface 33d are separated from each other as shown in Figure 10. At this time, the vibration of the container 33 guides seeds 7b that are not suitable for germination and other debris to the sorting holes 33c and discharges them, as shown in Figure 7.

[0081] Furthermore, when the imaging device 10 images the mounting surface 33d, the bottom surface 33a is illuminated by the light-emitting mechanism 35 in order to make it easier to detect the seeds 7 that are to be moved.

[0082] When the seed 7 to be moved is detected based on the image data captured from the mounting surface 33d, the vibration of the container 33 by the vibration mechanism 34 stops. Then, as shown in Figure 6, the seed 7 detected as the target to be moved is adsorbed by the adsorption holes 41 of the moving mechanism 40, making it ready to move.

[0083] If the seed 7 is suitable for germination, it is moved to the pot 3 by the transfer mechanism 40 and sown in the seeding hole 2a of the culture medium 2. If the seed 7 is not suitable for germination, such as a damaged or deformed seed 7b, it is moved to a tray 36 or the like by the transfer mechanism 40 and discarded.

[0084] When the amount of seeds 7 on the mounting surface 33d of the container 33 decreases, seeds 7 are replenished into the container 33 from the feeder 32. Then, the container 33 is vibrated until seeds 7 to be moved can be detected, and the detected seeds 7 are moved by the moving mechanism 40.

[0085] These operations are repeated in the seeding device 24. The pots 3 in which seeds 7 have been sown in the culture medium 2 are then transported by the pot conveyor 22 toward the watering device 25 (see Figure 4).

[0086] Next, referring to Figure 11, the process performed by the information processing device 12 in the seeding device 24 will be explained. During the operation of the seeding device 24, the information processing device 12 repeatedly performs the process shown in Figure 11.

[0087] First, in step S101, the information processing device 12 determines the amount of seeds 7 placed on the mounting surface 33d (see Figure 5) of the container 33. The information processing device 12 determines the amount of seeds 7 based on image analysis of the image data of the mounting surface 33d obtained from, for example, the imaging device 10. At this time, the information processing device 12 controls the emission of light by the light-emitting mechanism 35. As a result, light passes through the bottom surface 33a of the container 33, illuminating the seeds 7 on the mounting surface 33d. By imaging the mounting surface 33d with the imaging device 10 while the seeds 7 are illuminating, it becomes easier to detect the seeds 7 during image analysis. The information processing device 12 may control the emission of light by the light-emitting mechanism 35 each time it executes the process in step S101, or it may continuously control the emission of light by the light-emitting mechanism 35 from the start to the end of the process in Figure 11.

[0088] Alternatively, the seed placement mechanism 30 may be equipped with a weight sensor to detect the weight of the container 33. In this case, the information processing device 12 can measure the change in the weight of the container 33 based on the detection data obtained from the weight sensor and determine the amount of seeds 7 from the measurement result.

[0089] If the information processing device 12 determines in step S101 that the amount of seeds 7 is insufficient, it proceeds to steps S102 and S103 and controls the replenishment of seeds 7 to the mounting surface 33d. For example, the feeder 32 (see Figure 5) may be provided with an opening / closing mechanism (not shown) for opening and closing the supply hole 32b. In this case, the information processing device 12 controls the opening and closing of the opening / closing mechanism, thereby replenishing seeds 7 from the feeder 32 to the mounting surface 33d. The feeder 32 may also be provided with a vibration mechanism 34. In this case, the information processing device 12 controls the vibration mechanism 34, causing the feeder 32 to vibrate, and this vibration can release seeds 7 from the supply hole 32b into the container 33.

[0090] When seeds 7 are added to the mounting surface 33d, the information processing device 12 proceeds to step S101 and determines the amount of seeds 7 on the mounting surface 33d again.

[0091] On the other hand, if it is determined in step S101 that there is no shortage of seeds 7, the information processing device 12 proceeds to steps S102 to S104 to detect the seeds 7 to be moved. Based on the image analysis of the image data of the mounting surface 33d obtained from the imaging device 10, the information processing device 12 detects the seeds 7 to be moved from among the multiple seeds 7 placed on the mounting surface 33d.

[0092] At this time, the information processing device 12 can control the emission of light from the light-emitting mechanism 35. This is to make it easier to detect the moving seed 7 when analyzing the image data obtained from the imaging device 10. The information processing device 12 may control the emission of light from the light-emitting mechanism 35 each time it executes the process in step S104, or it may continuously control the emission of light from the start to the end of the process in Figure 11.

[0093] If the seed 7 to be moved cannot be detected in step S104, the information processing device 12 proceeds to steps S105 and S106, and vibrates the container 33 with the vibration mechanism 34. For example, as shown in Figure 9, it is difficult to detect the seed 7 to be moved when multiple seeds 7 are overlapping each other. However, by vibrating the container 33, the overlapping seeds 7 are dispersed and separated from each other, as shown in Figure 10, making it easier to detect the seed 7 to be moved. In addition, the vibration of the container 33 causes some of the seeds 7b that are unsuitable for germination to be discharged from the sorting holes 33c, as shown in Figure 7. Discharging the seeds 7b from the mounting surface 33d makes it easier to detect the seed 7 to be moved.

[0094] At this time, the information processing device 12 can control the vibration of the vibration mechanism 34 to change the magnitude and frequency of the vibration. By changing the magnitude and frequency of the vibration, the seeds 7 placed on the mounting surface 33d can be effectively dispersed. The information processing device 12 may also determine the degree of dispersion of the seeds 7 based on image analysis of the captured image data and change the vibration and frequency according to the degree of dispersion. Furthermore, the magnitude and frequency of the vibration for vibration control may be set according to the type of seed 7 and the type of container 33. In this case, for example, information on the magnitude and frequency of the vibration according to the type of seed 7 and the type of container 33 is recorded in the database 13. The information processing device 12 controls the vibration mechanism 34 based on the information obtained from the database 13.

[0095] After the vibration control of the vibration mechanism 34 is completed, the information processing device 12 proceeds to step S104 and detects the seed 7 to be moved again.

[0096] If a seed 7 to be moved is detected in step S104, the information processing device 12 proceeds to steps S105 through S107 to determine if the detected seed 7 is of good quality. In determining whether a seed is of good quality, the information processing device 12 determines that a seed 7 suitable for germination is of good quality. The information processing device 12 determines whether a seed is of good quality or not by comparing the characteristics of the seed 7 obtained from, for example, the database 13 with the characteristics of the detected seed 7. The characteristics here include, for example, size, color, and shape. A seed 7 that is determined not to be of good quality is, for example, a seed 7b that is unsuitable for germination due to defects, discoloration, or deformation.

[0097] If the information processing device 12 determines in step S107 that the seeds 7 to be moved are of good quality, it proceeds to steps S108 through S110, and moves the seeds 7 to be moved to the pot 3 using the moving mechanism 40. The seeds 7 are moved to the pot 3 while being adsorbed by the adsorption holes 41 of the moving mechanism 40, for example, by air suction. After that, the suction by the adsorption holes 41 is released, and the seeds 7 are sown in the sowing holes 2a of the culture medium 2 attached to the pot 3. After step S110, the information processing device 12 returns to step S101 and continues to execute the subsequent processes.

[0098] It is also possible to sow multiple seeds 7 in a single seeding hole 2a. The information processing device 12 controls the movement mechanism 40 so that an appropriate number of seeds 7 are sown in the seeding hole 2a, based on data regarding the number of seeds 7 to be sown, obtained from, for example, the database 13. In this case, the information processing device 12 also obtains data regarding the seeding interval of the seeds 7 from the database 13 and controls the movement mechanism 40 so that the seeds 7 are sown in the seeding hole 2a at that interval.

[0099] On the other hand, if the information processing device 12 determines in step S107 that the seed 7 to be moved is not of good quality, it proceeds to steps S108 and S109, and moves the seed 7 (7b) to be moved using the moving mechanism 40 and discards it. The information processing device 12 moves the seed 7 (7b) to be moved using the moving mechanism 40 to, for example, a receiving tray 36 (see Figure 5). After step S109, the information processing device 12 returns to step S101 and continues to execute the subsequent processes. The information processing device 12 may omit the processing in step S109. That is, it is possible to prevent the movement of seeds 7 that have been determined to be unsuitable by the movement mechanism 40. Unsuitable seeds 7 that remain in the container 33 without being moved are discharged, for example, through the vibration of the container 33. In addition, the information processing device 12 can also issue an alarm from a speaker (not shown) if it determines that the number of unsuitable seeds 7 has increased based on image analysis of the image data obtained from the imaging device 10. This allows an operator who has seen the alarm to remove the unsuitable seeds 7 remaining in the container 33.

[0100] Next, with reference to Figures 12 to 15, the water supply device 25 in the sowing area 111 will be described. The water supply device 25 is equipped with a pressing mechanism 50, as shown in Figure 12. The water supply device 25 also includes an information processing device 12 (see Figure 3). The operation of the pressing mechanism 50 is controlled by the information processing device 12.

[0101] The pressing mechanism 50 is equipped with multiple water supply pipes 50a that extend vertically and are movable vertically. The end face 50c of the water supply pipe 50a shown in Figure 13 is provided with multiple rectangular water supply holes 50b. Note that the shape of the water supply holes 50b formed on the end face 50c is not limited to rectangular, but can be various shapes such as elliptical. In addition, a water flow channel 50d is formed inside the water supply pipe 50a as shown in Figures 14 and 15. Water is supplied to the water flow channel 50d by a water supply pump or the like provided in the water supply device 25. The amount of water supplied is adjusted by the information processing device 12 controlling the operating amount of the water supply pump or the like. The water that has passed through the water flow channel 50d is discharged from the multiple water supply holes 50b. Note that the water discharged from the water supply holes 50b is supplied to the growing medium 2 in the pot 3, and may be mixed with liquid fertilizer or other substances necessary for the growth of plants 6.

[0102] The following describes the work process performed in the water supply device 25. First, the pots 3 in which seeds 7 have been sown in the culture medium 2 are transported by the pot transport conveyor 22 to the position of the pressing mechanism 50. At this time, the water supply pipe 50a of the pressing mechanism 50 is waiting in the standby position shown in Figure 14.

[0103] When the pot 3 is transported to a predetermined position where the end face 50c of the water supply pipe 50a and the culture medium 2 face each other, the water supply pipe 50a descends as shown in Figure 15, and the culture medium 2 is pressed by the end face 50c of the descending water supply pipe 50a. At this time, the culture medium 2 shrinks due to the pressure from the end face 50c.

[0104] When the culture medium 2 is pressed, water is supplied through the water supply hole 50b formed on the end face 50c that contacts the culture medium 2. Once the water supply from the water supply hole 50b is complete, the water supply pipe 50a rises to the standby position shown in Figure 14, and the pressure on the culture medium 2 by the water supply pipe 50a is released.

[0105] The sponge-like culture medium 2 exhibits its greatest water absorption capacity when it elastically deforms due to its own restorative force. Therefore, once the pressure is released, the culture medium 2 fully absorbs the supplied water. The seeds 7 also absorb sufficient water as a result of the water supplied to the culture medium 2. In this way, the seeds 7 receive water not only from the water supply device 25 but also from the water-containing culture medium 2. As a result, the culture medium 2 stores the water necessary for the germination of the seeds 7 sown in the sowing holes 2a.

[0106] The raised water supply pipe 50a waits again in the waiting position shown in Figure 14 until the next pot 3 is transported to the designated position. In the water supply device 25, these operations are repeated sequentially for each pot 3 that is transported. The pots 3 that have been supplied with water to the culture medium 2 are then transported by the pot transport conveyor 22 towards, for example, the pot moving device 26 (see Figure 4).

[0107] Next, with reference to Figure 16, the process performed by the information processing device 12 in the water supply device 25 will be explained. During the operation of the water supply device 25, the information processing device 12 repeatedly performs the process shown in Figure 16.

[0108] First, in step S201, the information processing device 12 lowers the water supply pipe 50a onto the culture medium 2 in the pot 3 that has been transported to a predetermined position (see Figure 15). At this time, the water supply pipe 50a is lowered with a fixed stroke that enters the storage space 3a of the pot 3. As the water supply pipe 50a lowers, the culture medium 2 is pressed against its end face 30c.

[0109] The stroke of the water supply pipe 50a is set to a length that allows the end face 50c to press against the culture medium 2. In order to allow the culture medium 2 to exert its water absorption force due to elastic deformation when the pressure is released, it is desirable to set the stroke so that the end face 50c reaches a position approximately two-thirds of the vertical length of the pot 3. Here, the vertical length of the pot 3 can also be considered as the vertical length of the storage space 3a. Alternatively, by setting the stroke so that the end face 50c reaches a position approximately two-thirds of the vertical length of the culture medium 2 installed in the pot 3, sufficient water absorption force of the culture medium 2 can also be ensured.

[0110] In step S202, the information processing device 12 starts supplying water to the culture medium 2 from the water supply hole 50b formed on the end face 50c of the water supply pipe 50a, while the culture medium 2 is being pressed by the end face 50c of the water supply pipe 50a.

[0111] At this time, the information processing device 12 determines in step S203 whether the water supply through the water supply pipe 50a has been completed.

[0112] For example, a flow sensor (not shown) for measuring the amount of water supplied from the water supply hole 50b may be provided in the water channel 50d of the water supply pipe 50a. This flow sensor is included in the water supply device 25. In this case, the information processing device 12 determines whether or not water supply to the culture medium 2 is complete based on the measurement data from the flow sensor. The information processing device 12 determines whether or not water supply is complete by comparing the amount of water supplied indicating completion of water supply obtained from the database 13 with the amount of water supplied based on the measurement data from the flow sensor.

[0113] Alternatively, for example, a weight sensor (not shown) for measuring the weight of the pots 3 being transported may be provided on the mounting unit 22a of the pot transport conveyor 22. This weight sensor is included in the water supply device 25. In this case, the information processing device 12 determines whether or not water supply to the culture medium 2 is complete based on the measurement data from the weight sensor. The information processing device 12 determines whether or not water supply is complete by comparing the weight of the pots 3 indicating completion of water supply obtained from the database 13 with the weight of the pots 3 based on the measurement data from the weight sensor.

[0114] For example, the information processing device 12 determines whether or not water supply to the culture medium 2 is complete based on the elapsed time since the start of water supply. The information processing device 12 determines whether or not water supply is complete based on whether the water supply time obtained from the database 13 has elapsed.

[0115] Database 13 records the amount of water supplied, the weight of the pots 3, and the watering time, indicating the completion of watering. Database 13 also records information on the appropriate amount of water supplied, the weight of the pots 3, or the watering time, depending on, for example, the type of plant 6, the type of pots 3, the type of growing medium 2, the surrounding environment such as the temperature and humidity of the sowing area 111, or a combination of these conditions.

[0116] The information processing device 12 obtains information on the amount of water supplied, the weight of the pot 3, or the water supply time corresponding to the set conditions from the database 13, and determines whether water supply is complete by comparing it with the amount of water supplied based on the flow sensor measurement, the weight of the pot 3 based on the weight sensor measurement, or the water supply time since the start of water supply.

[0117] When the information processing device 12 obtains information on the amount of water supplied or the weight of the pots 3 based on the surrounding environment of the sowing area 111 from the database 13, various sensors (not shown) for measuring information on the surrounding environment of the water supply device 25 may be provided within the equipment of the sowing area 111, such as a temperature sensor for measuring the temperature in the area and a humidity sensor for measuring the humidity in the area. These various sensors are included in the water supply device 25. In determining whether water supply is complete, the information processing device 12 obtains information on the amount of water supplied, the weight of the pots 3, or the water supply time corresponding to the measurement data from the various sensors from the database 13.

[0118] The information processing device 12 executes the determination process in step S203 until the water supply is complete. If it determines in step S203 that the water supply is complete, the information processing device 12 proceeds to steps S204 and S205, raising the water supply pipe 50a to the standby position shown in Figure 14. This releases the pressure on the culture medium 2 from the end face 50c of the water supply pipe 50a, and moisture is absorbed by the elastically deformed culture medium 2. After step S205, the information processing device 12 returns to step S201 and continues to execute the subsequent processes. The information processing device 12 may omit the processes in steps S203 and S204. In this case, the information processing device 12 can also execute the process in step S205 while the water supply to the culture medium 2 has started from the water supply hole 50b of the water supply pipe 50a and the water supply is continuing, raising the water supply pipe 50a and releasing the pressure on the culture medium 2.

[0119] According to the embodiment described above, the seeding device 24 in the seeding area 111 includes a container 33 on which multiple seeds 7 can be placed, a vibration mechanism 34 for vibrating the container 33, an imaging device 10 capable of imaging the seeds 7 placed in the container 33, a moving mechanism 40 for moving the seeds 7 from the container 33 to a pot 3 containing a culture medium 2 for sowing the seeds 7, and an information processing device 12 (see Figures 2, 3, 5, and 6). Here, the information processing device 12 performs a process to detect the seeds 7 to be moved by the moving mechanism 40 based on the image data captured from the imaging device 10 (see Figure 11). If the seeds 7 to be moved are detected, the information processing device 12 performs a process to move the detected seeds 7 to the pot 3 using the moving mechanism 40. On the other hand, if the seeds 7 to be moved cannot be detected, the information processing device 12 performs a process to vibrate the container 33 using the vibration mechanism 34.

[0120] As a result, the container 33 vibrates due to the vibration mechanism 34 until the seeds 7 to be moved can be detected. As the container 33 vibrates, the seeds 7 placed on the mounting surface 33d also vibrate, and the seeds 7 disperse so that they separate from each other.

[0121] By separating the seeds 7 from each other through vibration, the accuracy of detecting the seeds 7 from the image data captured by the imaging device 10 through image analysis can be improved. In addition, the movement mechanism 40 can prevent malfunctions such as moving multiple nearby seeds 7 together when attempting to move a single seed 7.

[0122] Furthermore, because the orientation of the seed 7 changes due to vibration, the imaging device 10 can obtain image data of the seed 7 from various angles. By performing image analysis based on multiple image data captured from various angles in this way, the detection accuracy of the seed 7 can be improved.

[0123] Furthermore, the seeding device 24 enables the automatic dispersal of seeds 7 in the container 33, selection of seeds 7 to be moved, and transfer of seeds 7 to the growing medium 2 in the pots 3. This expands the automation of the plant production system 100 and improves production efficiency. In addition, it improves the hygienic quality of the plants 6 by eliminating human intervention.

[0124] Furthermore, by consolidating these operations into a single piece of equipment, the seeding device 24, the area required for the seeding device 7 can be reduced, thus saving space in the plant factory. Consolidating the operations into the seeding device 24 can lead to a reduction in equipment size and the number of units, as well as simplification of control, resulting in cost savings for the entire plant production system 100.

[0125] In the seeding device 24 of this embodiment, it is desirable to have sorting holes 33c through which the seeds 7 to be moved cannot pass (see Figures 5 and 6). For example, the width of the sorting holes 33c is set to allow defective or deformed seeds 7b that are unsuitable for germination, as well as debris mixed in with the seeds 7, to pass through (see Figures 7 and 8). This allows the seeds 7b and debris to be moved and discharged through the sorting holes 33c when the container 33 is vibrated to separate the seeds 7 (see Figure 7). In this way, by removing objects other than the seeds 7 to be moved, the accuracy of detecting the seeds 7 from the image data captured by the imaging device 10 through image analysis can be improved.

[0126] Furthermore, it is desirable that the bottom surface 33a of the container 33 be translucent, and that the seeding device 24 be equipped with a light-emitting mechanism 35 capable of projecting light onto the bottom surface 33a (see Figure 6). The light projected from the light-emitting mechanism 35 passes through the bottom surface 33a, illuminating the seeds 7 placed on the placement surface 33d. By capturing images of the seeds 7 while they are illuminated by the imaging device 10, the accuracy of detecting the seeds 7 from the captured image data by image analysis can be improved.

[0127] In the seeding device 24 of this embodiment, it is desirable that the information processing device 12 performs the following processes: determining whether the detected seeds 7 are good based on the captured image data, and moving the detected seeds 7 to the pot 3 using the moving mechanism 40 if they are determined to be good (see Figure 11). This makes it possible to sow seeds 7 suitable for germination in the culture medium 2, and improves the germination rate of seeds 7 in the sowing area 111. Therefore, it is possible to improve the yield of plant production 6 in the plant production system 100.

[0128] In the seeding device 24 of this embodiment, it is desirable that the information processing device 12 performs a process of moving the seeds 7 to the culture medium 2 using the moving mechanism 40 based on the seeding interval set according to the type of plant 6 (see Figures 5 and 11). This allows, for example, when sowing multiple seeds 7 in one culture medium 2 for multi-seed sowing cultivation, to sow each seed 7 at an optimal interval according to the variety of plant 6. Therefore, the germination rate of the seeds 7 in the sowing area 111 can be improved, and the yield of plant production 6 can be improved.

[0129] In this embodiment, the seeding device 24 can be considered to include the pot transport conveyor 22 and the pots 3 equipped with the culture medium 2 (see Figure 5). Furthermore, the seeding device 24 can also be considered to include the database 13 (see Figure 2) accessible by the information processing device 12.

[0130] Furthermore, according to the embodiment, the water supply device 25 of the sowing area 111 includes a pressing mechanism 50 capable of pressing the culture medium 2 attached to the pot 3, and having a water supply hole 50b formed on the end surface 50c that contacts the culture medium 2 when pressing, and an information processing device 12 (see Figures 3 and 12). The information processing device 12 performs the process of causing the pressing mechanism 50 to press the culture medium 2, and the process of supplying water from the water supply hole 50b while the culture medium 2 is pressed (see Figure 11). In addition, the information processing device 12 can perform the process of stopping the water supply from the water supply hole 50b and releasing the pressing of the culture medium 2 by the pressing mechanism 50 when the water supply to the culture medium 2 is complete.

[0131] When water is supplied while the culture medium 2 is compressed, the culture medium 2 elastically deforms due to its restorative force upon release of the pressure, and water is absorbed. At this time, the seeds 7 in the culture medium 2 also become sufficiently moist. Thus, the seeds 7 receive moisture not only from the water supply device 25 but also from the moistened culture medium 2. This allows the culture medium 2 to efficiently distribute the moisture necessary for germination. Furthermore, by ensuring a stable moisture level in the culture medium 2, the germination rate of the seeds 7 can be improved. Furthermore, the culture medium 2 may be made of a material that absorbs moisture without undergoing elastic deformation due to pressure.

[0132] With this water supply device 25, tasks such as watering the growing medium 2 can be performed automatically. This expands the automation of the plant production system 100 and improves production efficiency. In addition, it improves the hygienic quality of the plants 6 by eliminating human intervention.

[0133] Furthermore, by consolidating these operations into a single piece of equipment, the water supply device 25, the area required for the equipment to supply water to the growing medium 2 can be reduced, thus saving space in the plant factory. Consolidating the operations into the water supply device 25 can lead to a reduction in equipment size and the number of units, as well as simplification of control, resulting in cost savings for the entire plant production system 100.

[0134] In the water supply device 25 of this embodiment, the pressing mechanism 50 presses the culture medium 2 with the seeds 7 sown in the seeding holes 2a of the culture medium 2. By positioning the seeds 7 in the seeding holes 2a, it is possible to prevent damage to the seeds 7 from occurring when the end face 50c of the pressing mechanism 50 comes into contact with the culture medium 2 as it descends for pressing. Furthermore, when water is supplied while the end face 50c is in contact with the culture medium 2, positioning the seeds 7 in the space formed by the end face 50c and the seeding holes 2a prevents the seeds 7 from being ejected from the culture medium 2 by the force of the water supply. In addition, by sowing the seeds 7 in the seeding holes 2a of the culture medium 2, it is also possible to prevent the position of the seeds 7 in the culture medium 2 from shifting due to the shaking of the pots 3 when they are transported on the pot conveyor 22.

[0135] In this embodiment, the water supply device 25 is preferably equipped with a flow sensor (not shown) for measuring the amount of water supplied from the water supply hole 50b. At this time, the information processing device 12 performs a process to determine whether or not water supply to the culture medium 2 has been completed based on the measurement data from the flow sensor (see Figure 16). Here, water is supplied to the culture medium 2 of each transported pot 3 to a predetermined amount. Therefore, the amount of water required for germination can be supplied to the culture medium 2 automatically and stably.

[0136] In this embodiment, the water supply device 25 is preferably equipped with a weight sensor (not shown) that measures the amount of water supplied from the water supply hole 50b. At this time, the information processing device 12 performs a process to determine whether or not water supply to the culture medium 2 has been completed based on the measurement data from the weight sensor (see Figure 16). Here, the weight of the pot 3 in the state where the culture medium 2 has been supplied with the necessary amount of water is set in advance. Then, water is supplied to the culture medium 2 until each transported pot 3 reaches the set weight. By this means as well, the amount of water required for germination to be supplied to the culture medium 2 can be automatically and stably carried out.

[0137] In the water supply device 25 of this embodiment, it is desirable that the information processing device 12 performs a process to supply water from the water supply hole 50b based on the amount of water supplied according to the type of pot 3 or the type of culture medium 2 (see Figure 16). This makes it possible to flexibly set the amount of water supplied even when different amounts of water are required depending on the type of pot 3 or culture medium 2 used.

[0138] In the water supply device 25 of this embodiment, it is desirable that the information processing device 12 performs a process to supply water from the water supply hole 50b based on the amount of water supplied according to the surrounding environment (see Figure 16). This makes it possible to flexibly set the amount of water supplied according to the surrounding environment, such as the temperature, humidity, and brightness of the sowing area 111 where the water supply device 25 is installed.

[0139] In this embodiment, the water supply device 25 can be considered to include the pot transport conveyor 22 and the pot 3 equipped with the culture medium 2 (see Figure 5). Furthermore, the water supply device 25 can also be considered to include the database 13 (see Figure 2) accessible by the information processing device 12.

[0140] In this embodiment, the information processing device 12 is configured with a microprocessor and performs control processing based on a program. The control processing that executes the procedures shown in Figures 11 and 16 can be realized by a program executed by the CPU of the information processing device 12. Such a program can be pre-recorded on a recording medium built into a computer or other device, or on ROM in a microcomputer with a CPU. It can also be temporarily or permanently stored (recorded) on a removable recording medium such as semiconductor memory or a memory card. In addition, such a program can be installed on a personal computer or the like from a removable recording medium, or downloaded from a download site via a network such as the Internet.

[0141] Furthermore, the information processing device 12 of this embodiment can improve the accuracy of various judgments by using machine learning with an AI (artificial intelligence) engine. For example, in step S108 of Figure 11, the information processing device 12 can improve the accuracy of its judgment by using machine learning when making a good product judgment. For example, by accumulating image data of various plants 6 throughout the process from sowing to harvesting and performing machine learning, it becomes possible to link image data of seeds 7 at the time of sowing with image data of plants 6 at the time of harvesting. Based on this link between seeds 7 at the time of sowing and plants 6 at the time of harvesting, the information processing device 12 can identify seeds 7 that are likely to be abnormally cultivated at the time of harvest from among the imaged seeds 7. As a result, it becomes possible to judge seeds 7 that are highly likely to become abnormal in the future as good products.

[0142] Furthermore, for example, when setting the conditions for water supply completion in step S203 of Figure 16, machine learning can be used to improve the accuracy of these settings. For instance, by accumulating information on the surrounding environment, such as temperature, humidity, and brightness, of the facility where the good quality plants 6 were grown, as well as data on the amount of water supplied at that time, and performing machine learning, it becomes possible to set an appropriate amount of water to supply under each condition.

[0143] Finally, the effects described in this disclosure are illustrative and not limiting; other effects may be achieved, or only some of the effects described in this disclosure may be achieved. Furthermore, not all combinations of configurations described in the embodiments are necessarily essential for solving the problem. [Explanation of Symbols]
