[0012] Each embodiment will be described below with reference to the drawings. In all drawings, the same or corresponding components are designated by the same reference numerals, and common descriptions will be omitted.

[0013] First Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings.

[0014] 1 is a diagram showing an example of the configuration of a management system S according to the present disclosure. The management system S includes a server device 10 and an RFID device 30. The server device 10 is connected to a terminal device PC. The server device 10 and the RFID device 30 are connected to a network via a wireless communication station. Note that a wired communication device may be used instead of the wireless communication station.

[0015] The server device 10 is connected to a terminal device PC via a network. A user U accesses the server device 10 from the terminal device PC. The user U is a person who manages fruit cultivation, and acquires and analyzes growth information indicating the growth level of the fruit at each of multiple growth stages in the fruit cultivation process from the server device 10. Fruit is a type of fresh produce. Fruits grow on branches or vines of trees growing in a field, or vines on branches. A terminal device PC may not be required, and in this case, the user U may operate the server device 10 directly.

[0016] There may be one or more fields. Multiple trees or multiple branches may grow in one field. One tree may have multiple branches. Each of the multiple branches may have one or multiple vines. After obtaining the growth information, the user U writes the growth information to the RFID tag TG attached to the fruit vine using the RFID device 30.

[0017] The growth information includes a field identifier that identifies the field in which the fruit-bearing tree or branch grows, location information that indicates the location of the fruit in the field, variety information that indicates the variety of the fruit, and stage information that indicates the first growth stage in the fruit's growth process. The field identifier and location information can uniquely identify fruits growing in one or more fields. The first growth stage may be the time when a new shoot for the fruit sprouts from the branch. When the new shoot sprouts from the bud seat of the branch, a user U attaches an RFID tag TG that is unique to the new shoot to the new shoot or to a branch near the new shoot.

[0018] When the user U acquires the growth information, the user U transmits the growth information to the wireless communication station using the RFID device 30. The server device 10 receives the growth information via the wireless communication station and the network NW. The server device 10 acquires performance information indicating past growth performance for multiple fruits. The multiple fruits may be multiple for a single variety, or multiple samples may be defined for each of multiple different varieties of fruit. The past growth performance may be the number-average number of days for multiple fruits of a specific variety up to each stage included in the process from when new shoots sprout from tree branches or when seedlings are planted to when they are harvested and delivered to consumers. The past growth performance may further include at least one of the average outdoor temperature, the hours of sunlight per day, and the average humidity for the specific variety of fruit from when new shoots sprout from tree branches or when seedlings are planted to when they are harvested.

[0019] The server device 10 estimates the second time point based on the growth information and performance information and outputs it to a display device or the like. The display device may be a liquid crystal display device. The second time point corresponds to a second growth stage for the fruit, which is a growth stage subsequent to the first growth stage. The second growth stage may be the first time point, i.e., the growth stage subsequent to the first growth stage, which is the current growth stage. For example, if the first growth stage is the germination of shoots on a fruit-bearing tree, the second growth stage may be the flowering of the fruit.

[0020] After confirming the second time point on a display device or the like, user U goes to the field at or around the second time point and performs work corresponding to the second growth stage on the fruit buds, inflorescences, or clusters. For example, if the fruit is grapes and the second growth stage is the flowering of inflorescences from the bud seat, user U may perform cluster formation work on all inflorescences growing in the field. Cluster formation work involves removing unnecessary accessory spikes and pedicels from the inflorescence. This is expected to remove grapes that are not growing well, stabilize the shape of the grape cluster, and increase the rate of high-quality grapes. Note that for grapes that have not flowered at this stage, cluster formation work may not be performed and the grapes may be thinned out by cutting off the bud seat from the branch or vine. This is expected to ensure that grapes that are growing well receive sufficient nutrients. User U may collect the RFID tags TG of the thinned grapes.

[0021] When the work corresponding to the second growth stage is completed, the user U writes the second time point to the RFID tag TG using the RFID device 30. The user U performs this writing operation for all fruits for which the work corresponding to the second growth stage has been completed in the field. In this case, since the second growth stage corresponds to the current growth stage, the user U may update the first time point by setting the time point corresponding to the second growth stage as the first time point, or may manage the next growth stage as the third growth stage and accumulate it as performance information. The user U accesses the server device 10 from the terminal device PC to refer to and analyze the growth information and make a fruit cultivation plan. In this way, the user U uses the server device 10 and the RFID device 30 to repeatedly and continuously manage the fruit growth based on the growth information and performance information until the fruit reaches the consumer.

[0022] 2 is a diagram showing an example of a functional configuration diagram of a server device 10 according to the present disclosure. The server device 10 includes an acquisition unit 11, a processing unit 12, an output unit 13, a storage unit 14, and a communication unit 15. The acquisition unit 11 accepts operations and input of information from outside. The processing unit 12 processes and processes information and data acquired from outside. The processing unit 12 may read and execute commands from the storage unit 13, or may execute commands stored within the processing unit 12.

[0023] The output unit 13 outputs information and data to the outside. The storage unit 14 stores information, data, and commands acquired from the outside, and information and data processed and modified by the processing unit 12. The communication unit 15 transmits information and data to an external device, and transmits and receives information and data from an external device.

[0024] 3 is a diagram showing an example of a functional configuration diagram of an RFID device 30 according to the present disclosure. The RFID device 30 includes a reading unit 31, a writing unit 32, a processing unit 33, an output unit 34, and a communication unit 35. The RFID device 30 may further include a storage unit 36 ​​and an acquisition unit 37.

[0025] The reading unit 31 and writing unit 32 each read information from or write information to the IC chip included in the RFID tag TG via communication using an antenna included in the RFID tag TG. The processing unit 33 processes the information and data handled by the reading unit 31 and writing unit 32 and the information and data received by the communication unit 35. The output unit 34 outputs the information and data handled by the RFID device 30 to the outside. The communication unit 35 may be compatible with a wireless LAN interface, a Bluetooth interface, or a USB interface. The communication unit 35 is connected to the network NW via a wireless communication station and communicates with the server device 10.

[0026] The RFID tag TG includes at least an IC chip and an antenna. The IC chip is a memory element that stores growth information. The RFID tag TG may be a passive tag without a power source or an active tag with a built-in power source. The RFID tag TG may be a UHF tag that uses the UHF frequency band for reading and writing, or an NFC tag that uses the 13.56 MHz band.

[0027] FIG. 4 is a diagram showing an example of a branch configuration for a grapevine according to the present disclosure. In this case, grapes are an example of a fruit or vegetable. The configuration example in FIG. 4 is a branch formation method used for short-shoot grape cultivation. FIGS. 4(a)-(d) may be referred to as the straight-branch type, H-branch type, double H (WH) type, and all-back type, respectively. In FIG. 4(a), the straight-branch type has a main branch Tr growing almost vertically from the ground, and two sub-main branches Br growing horizontally in opposite directions. The sub-main branches Br branch off from a single main branch Tr. In FIG. 4(b), the H-branch type has four sub-main branches Br growing horizontally to form an H shape. Note that the main branch Tr may be the trunk of a tree.

[0028] In Figure 4(c), in the WH type, eight sub-main branches Br extend horizontally from the main branch Tr, which grows almost vertically to the ground. The eight sub-main branches Br extend as if forming two H shapes. In Figure 4(d), on the slicked-back side, two sub-main branches Br branch off from the main branch Tr, which grows vertically to the ground, and the two sub-main branches Br extend horizontally to form a concave or U shape.

[0029] By selecting the branch configuration shown in Figure 4, the main branches Tr will grow in the field at the intersections of the horizontal and vertical lines that make up a rectangular grid, and the sub-main branches Br will be laid out in a shape similar to a checkerboard. This makes it easier to express the position of the new shoots growing from the bud loci Bd contained in the sub-main branches Br in two-dimensional coordinates. Therefore, it is expected that the position of the grape bunches growing from the new shoots will be easily identified in the field. Bud loci Bd will be discussed later.

[0030] FIG. 5 is a diagram showing an example of the configuration of sub-main branches Br and bud orifices Bd in a grapevine according to the present disclosure. Bud orifices Bd are included at predetermined intervals on the horizontally extending sub-main branches Br. New shoots emerge from the bud orifices Bd, and as the new shoots grow, they eventually become bunches of grapes. If too many new shoots grow on a sub-main branch Br, the nutrients supplied to each bunch may decrease, resulting in insufficient growth. Therefore, ensuring sufficient spacing between bud orifices Bd increases the likelihood of producing high-quality grapes, but this may also increase the production cost per bunch, so there may be a trade-off between these two.

[0031] 6 is a diagram showing an example of attaching an RFID tag TG to a grapevine according to the present disclosure. A sub-main branch Br extends horizontally to the ground. A grape fruit Fr, which has grown from a bud center Bd included in the sub-main branch Br, is suspended from the sub-main branch Br by a vine V. The RFID tag TG is attached to the vine V, but if there is only one cluster on the sub-main branch Br, the RFID tag TG may be attached somewhere on the sub-main branch Br, or the RFID tag TG may be attached to a sub-main branch Br near the fruit Fr so that any particular fruit Fr can be identified.

[0032] 7 and 8 are flowcharts showing the flow of a series of processes in the management method according to the present disclosure. In Figs. 7 and 8, grapes will be used as an example of the fruit and vegetable.

[0033] In step S100, the processing unit 12 initializes the growth information corresponding to each of the predetermined number of prepared RFID tags TG. The predetermined number may be the number of grape bunches that can grow in the field managed by the user U. The processing unit 33 may perform the initialization process instead of the processing unit 12.

[0034] In step S101, the acquisition unit 11 acquires performance information and stores it in the storage unit 14. The performance information includes performance values ​​for at least one of the following when grapes were grown in the past, including the previous year: the date of shoot germination associated with the field identifier and location information, the date of cluster formation work, the rachis length, the number of cluster rows, the date of flowering, the date of gibberellin treatment, the period of fruit thinning and the number of grapes, the period of cluster hardening, the period of cluster softening and shoot management, the harvest date, the weight of the cluster on the harvest date, the date of veraison, the sugar content of the cluster on the harvest date, and the average temperature and average hours of sunshine from the time the shoots sprouted until the harvest date.

[0035] In step S102, the acquisition unit 11 acquires growth information and stores it in the memory unit 14. The acquisition of growth information may be achieved by the acquisition unit 11 accepting input of growth information from the user U. The growth information includes a field identifier that identifies a field that includes a sub-main branch Br on which a new shoot has grown, location information that indicates the position of the new shoot in the field, variety information that indicates a grape variety, and stage information that indicates a first growth stage in the growth process of a single grape. The field is one of multiple fields managed by the user U. The field identifier may be expressed in any way as long as it can uniquely identify the field.

[0036] The positional information may be expressed in any manner as long as it allows the position of the bud locus Bd to be identified. For example, the position of a specific bud locus Bd may be identified by positional information A-B2-C3. Here, A may indicate a main branch Tr in a specific field, B2 may indicate a sub-main branch Br on the main branch Tr, and C3 may indicate a bud locus Bd included in the sub-main branch Br. As new shoots sprout from bud locus A Bd and growth progresses to flower spikes and clusters, the positional information -B2-C3 will ultimately identify a cluster of grapes.

[0037] In addition, the location information may be used to identify the position of the bud locus Bd in the field by its distance on a two-dimensional coordinate system with the main branch Tr as the origin, or by the number of the bud locus Bd in the positive or negative direction of the Y axis and the positive or negative direction of the X axis on a two-dimensional coordinate system with the main branch Tr as the origin.

[0038] "One fruit or vegetable" refers to the grape currently being targeted for management among the grapes growing from a bud locus Bd included in a sub-main branch Br in the field. "One fruit or vegetable variety" refers to the grape variety. The grape variety may be, for example, Kyoho, Pione, or Muscat. The first growth stage may be when a new shoot sprouts from the bud locus Bd.

[0039] In step S103, the acquisition unit 11 acquires the germination date, which is the date on which a new shoot emerges from the bud locus Bd. The germination date may also be referred to as the first time point.

[0040] In step S104, the processing unit 12 updates the growth information by including the germination date of the new shoots in the stage information.

[0041] In step S105, the writing unit 32 writes the growth information to the RFID tag TG. The growth information may be received by the communication unit 35 from the communication unit 15, or may be acquired by an acquisition unit 37 separately provided in the RFID device 30, and this is the same for the subsequent growth information writing process.

[0042] In step S106, the processing unit 12 estimates the date of the cluster formation work based on the performance information and the growth information. The date of the cluster formation work may be referred to as a second time point, and information indicating the second time point may be referred to as time information. The processing unit 12 may refer to the average temperature since the grape harvest of the previous year, the average temperature since the shoots sprouted, or the average sunshine hours from the performance information. For example, if the average temperature since the shoots sprouted is higher than that of the previous year indicated by the performance information, or if the average sunshine hours since the shoots sprouted are longer than that of the previous year indicated by the performance information, the processing unit 12 may set the date of the cluster formation work to an earlier date than that of the previous year. If the average temperature since the shoots sprouted is lower than that of the previous year indicated by the performance information, or if the average sunshine hours since the shoots sprouted are shorter than that of the previous year indicated by the performance information, the processing unit 12 may set the date of the cluster formation work to a later date than that of the previous year. The same applies to each subsequent growth stage.

[0043] In step S107, the output unit 13 outputs time information indicating the estimated date on which the bunch forming work will be performed. The communication unit 35 may transmit the time information to the terminal device PC instead of the output unit 13. Based on the time information, the user U can plan the date on which the bunch forming work, which is the next growth stage, will be performed.

[0044] In step S108, the acquisition unit 11 acquires information indicating the date on which the user U performed the tuft forming work and the number of tufts.

[0045] In step S109, the processing unit 12 adds the date of the bunch forming operation and the number of rows of the bunch to the growth information as stage information.

[0046] In step S110, the writing unit 32 writes the growth information into the RFID tag TG.

[0047] In step S111, the processing unit 12 estimates the flowering date based on the performance information and growth information. The flowering date may be, for example, three weeks after the germination of new shoots.

[0048] In step S112, the output unit 13 outputs time information indicating the estimated flowering date.

[0049] In step S113, the acquisition unit 11 acquires information indicating the actual flowering date. This acquisition process may be realized by the acquisition unit 11 accepting input of information indicating the actual flowering date after the user U confirms the actual flowering date in the field.

[0050] In step S114, the processing unit 12 adds information indicating the actual flowering date to the stage information, and adds the stage information to the growth information.

[0051] In step S115, the writing unit 32 writes the growth information into the RFID tag TG.

[0052] In step S116, the processing unit 12 estimates the date of gibberellin treatment based on the performance information and growth information. Gibberellin treatment is a process in which the bunches are soaked in gibberellin, a plant hormone. This treatment renders the grapes in the bunch seedless and promotes grape enlargement during the growth process.

[0053] In step S117, the output unit 13 outputs time information indicating the estimated date of implementation of the gibberellin treatment.

[0054] In step S118, the acquisition unit 11 acquires information indicating the date on which the gibberellin treatment was performed. This acquisition process may be realized by the acquisition unit 11 receiving input of information indicating the date on which the gibberellin treatment was performed after the user U performed the gibberellin treatment in the field.

[0055] In step S119, the processing unit 12 adds information indicating the date on which the gibberellin treatment was carried out to the stage information, and adds the stage information to the growth information.

[0056] In step S120, the writing unit 32 writes the growth information into the RFID tag TG.

[0057] The subsequent processing will be explained with reference to FIG.

[0058] In step S121, the processing unit 12 estimates the grape thinning period based on the performance information and growth information. Grape thinning is the process of thinning out some of the grapes in a bunch. It is expected that grape thinning will evenly distribute the grapes in the bunch, make the size of the grapes in the bunch uniform, and ensure that nutrients are sufficiently distributed among the grapes. The grape thinning process will be described later using Figure 9.

[0059] In step S122, the output unit 13 outputs time information indicating the estimated thinning period.

[0060] In step S123, the acquisition unit 11 acquires information indicating the period during which the de-berrying work was actually performed, information indicating the stalk length, and information indicating the number of grains per tassel. This acquisition process may be realized by the acquisition unit 11 accepting input from the user U of information indicating the period during which the de-berrying work was actually performed, information indicating the stalk length, and information indicating the number of grains per tassel, after the user U has performed the de-berrying work in the field.

[0061] In step S124, the processing unit 12 adds information indicating the period during which the fruit thinning work was actually carried out, information indicating the axis length, and information indicating the number of fruit per cluster to the stage information, and adds the stage information to the growth information.

[0062] In step S125, the writing unit 32 writes the growth information into the RFID tag TG.

[0063] In step S126, the processing unit 12 estimates the hardening period, softening period, and new shoot management period based on the performance information and growth information. The hardening period and softening period indicate the periods during which the grapes contained in the bunch become hard and soft, respectively. The new shoot management period is the work of appropriately thinning out the bud loci Bd contained in the sub-main branches Br. The processing unit 12 may also estimate the time of coloring of the bunch based on the performance information and growth information. The hardening start date may be 30 days after full bloom of the flowers, and the softening start date may be 45 days after full bloom of the flowers. The coloring start date may be 60 days after full bloom of the flowers. These dates may be earlier or later depending on the temperature or hours of sunlight.

[0064] In step S127, the output unit 13 outputs time information indicating the estimated hardening period, softening period, and new shoot management period. The time information may further indicate the coloring period of the bunches.

[0065] In step S128, the acquisition unit 11 acquires information indicating the period during which the new shoot management work was actually performed. This acquisition process may be realized by the acquisition unit 11 accepting input of information indicating the period after the new shoot management work is performed in the field by the user U. The acquisition unit 11 may further acquire information indicating the time when the bunches actually became colored.

[0066] In step S129, the processing unit 12 adds information indicating the period during which the new shoot management work was actually performed to the stage information, and adds the stage information to the growth information. The stage information may further include information indicating the time when the bunches actually became colored.

[0067] In step S130, the writing unit 32 writes the growth information into the RFID tag TG.

[0068] In step S131, the processing unit 12 estimates the harvest date and the weight of the bunches based on the performance information and growth information. The harvest date may be 90 days after the flowers are in full bloom. The harvest date may be earlier or later depending on the temperature or the hours of sunlight.

[0069] In step S132, the output unit 13 outputs time information indicating the estimated harvest date and information indicating the weight of the bunch. The weight of the bunch may be 800 g.

[0070] In step S133, the acquisition unit 11 acquires time information indicating the actual harvest date, information indicating the weight of the bunch, and information indicating the sugar content of the kernels contained in the bunch. This acquisition process may be realized by the acquisition unit 11 accepting input of information indicating the date of the harvest, information indicating the weight of the bunch, and information indicating the sugar content after the user U has performed the harvesting work and measured the weight and sugar content of the bunch. The sugar content may be acquired by the user U through measurement using a non-contact sensor. The acquisition unit 11 may further acquire information indicating the number of kernels per bunch.

[0071] In step S134, the processing unit 12 adds time information indicating the actual harvest date, information indicating the weight of the bunch, and information indicating the sugar content to the stage information, and adds the stage information to the growth information. The stage information may further include information indicating the number of kernels per bunch.

[0072] In step S135, the writing unit 32 writes the growth information into the RFID tag TG.

[0073] In step S136, the acquisition unit 11 acquires time information indicating the shipping date of the bunch.

[0074] In step S137, time information indicating the shipping date is added to the stage information, and the stage information is added to the growth information.

[0075] In step S138, the writing unit 32 writes the growth information to the RFID tag TG. In this case, the RFID tag TG may be attached to the grape bunch or the vine connected to the grape bunch. The growth information may be read by a distributor using the reading unit 31 during the grape distribution process. After shipping, the processing unit 12 may generate a two-dimensional code based on the growth information. The output unit 13 may print the two-dimensional code on a sticker using a printer or the like. The two-dimensional code represents the growth information by its geometric pattern. Thereafter, the sticker including the two-dimensional code may be attached to the harvested grape bunch or the vine connected to the grape bunch. The sticker including the two-dimensional code may be attached to any of the wrapping paper, bag, container, or box that stores the grape bunch.

[0076] After that, when the grapes are shipped, distributors can refer to the growing information from the RFID tag TG or 2D code to inspect them, implement quality control, and manage sales. Consumers can read the growing information from the RFID tag TG or 2D code using a terminal device such as a smartphone, estimate their preferred sweetness, and select the ripe time to eat them.

[0077] The processes from step S100 to step S138 are performed for all grapes contained in all fields managed by user U. If the growth of a spike or cluster is poor and the process of step S107 cannot be performed, user U may thin out such spikes or clusters. For example, in each field, if the estimated date for cluster formation work for each cluster has actually passed for 80% of all spikes or clusters, user U may perform cluster formation work, and if the growth of spikes or clusters is poor, user U may thin out such spikes or clusters. user U may collect the RFID tags TG corresponding to the thinned spikes or clusters.

[0078] For example, in step S117, if the estimated date for gibberellin treatment for 80% of all bunches in each field has actually passed, the user U may perform the gibberellin treatment, and if the growth of the bunches is not good, the user U may thin out such bunches. The user U may collect the RFID tags TG corresponding to the thinned bunches.

[0079] Similarly, in step S123, if the start date of the estimated grain thinning period for 80% of all bunches in each field has actually passed, the user U may carry out grain thinning work, and if the growth of the bunches is not good, the user U may thin out such bunches. The user U may collect the RFID tags TG corresponding to the thinned bunches.

[0080] The "first time point" may be the latest growth stage at which the work has been completed, and the "second time point" may be the next growth stage. Some of the work at multiple growth stages described in steps S100 to S138 may be omitted.

[0081] In FIGS. 7 and 8, grapes are given as an example of fruits and vegetables, but the fruits and vegetables are not limited to grapes and may be, for example, pears, apples, tomatoes, or cucumbers.

[0082] According to the above aspect, user U can efficiently carry out work at each stage up to delivery of fruits and vegetables to consumers, taking into consideration the growth state of each fruit and vegetable tree grown in the field. For example, user U can appropriately plan work at the field at each growth stage of the fruits and vegetables, and appropriately carry out harvesting, inspection, and shipping management of the fruits and vegetables. Distributors and retailers can efficiently carry out inspection, quality control, and sales management of the fruits and vegetables. Consumers can eat the fruits and vegetables according to their preferences, or use them to make processed products.

[0083] FIG. 9 is a diagram showing an example of arrangement of grape bunches when thinning the grapes according to the present disclosure.

[0084] As shown in Figure 9, the grape bunches can be divided into, for example, the first to fourth layers. In the thinning process, each layer can be further divided into two rows, one above the other, with each row containing three grapes, or the number of grapes in each row can be increased or decreased depending on the grape variety or layer. Alternatively, the user U can decide on a predetermined number of grapes per bunch and thin the grapes so that the number of grapes in each layer is evenly distributed.
