[0008] <Problem to be Solved> The measuring instrument disclosed in Patent Document 1 includes a housing containing a processing unit for performing analytical processing, a measurement head for emitting and receiving measurement light, and a cable extending from the housing to the measurement head. An operator performs measurements while holding the measurement head in their hand. Measured quality information is recorded in association with management information (identification information) such as identification information for the fruit being measured and the tree on which the fruit is grown. However, since the operator's hands are occupied, manually inputting management information such as identification information into, for example, a separate mobile terminal device makes the work cumbersome and reduces operability. Therefore, the present invention provides a fruit management device that can improve the operability of fruit quality management, a fruit management system including the fruit management device, and a computer program for operating a computer as the fruit management device.

[0009] <Effect> Improves workability in fruit quality control.

[0010] <Outline of Embodiments of the Present Disclosure> The following is a summary of embodiments of the present disclosure. (1) A fruit management device of this embodiment is a management device having a processing unit that executes information processing to manage quality information of fruits using identification information related to one or both of fruits and fruit-bearing trees. The fruit management device includes a first input unit that acquires the quality information measured by a measuring device and a second input unit that acquires voice as input. The processing unit executes the storage process when the voice input to the second input unit instructs execution of a storage process to save the quality information. According to the fruit management device having the above configuration, the storage process associates the identification information with the quality information acquired by the measuring device and stores it. The storage process can be easily executed using the voice (vocalization) of an operator acquired by the second input unit. This eliminates the need for manual input by an operator, improving the operability of fruit quality management.

[0011] (2) In the storage process, if the voice commanding execution can be converted into the identification information, the processing unit converts the voice commanding execution into the identification information and stores the converted identification information in association with the quality information. With the fruit management device having the above configuration, simply by an operator uttering the identification information, not only can the identification information be obtained but also the storage process for storing the quality information can be executed.

[0012] (3) In the fruit management device of (1), when the second input unit acquires a voice instructing the execution and another voice different from the voice instructing the execution, in the storage process, if the other voice can be converted into the identification information, the processing unit converts the other voice into identification information and stores the converted identification information in correspondence with the quality information.

[0013] According to a fruit management device having the above configuration, even if the identification information is not a voice (called an execution voice) for executing a preservation process, an operator can not only obtain the identification information but also execute a preservation process that preserves quality information by simply uttering an execution voice and a voice that can be converted into identification information.

[0014] (4) In the fruit management device of (2) or (3), the processing unit determines that the voice commanding execution or another voice different from the voice commanding execution can be converted into the identification information when the voice commanding execution or another voice different from the voice commanding execution can be converted into a character string represented by at least one of symbols and alphanumeric characters and the character string can be distinguished from words. According to the fruit management device having the above configuration, the processing unit can convert the voice uttered by the worker or the like into the identification information.

[0015] (5) In any one of the fruit management devices (1) to (4), the fruit management device is provided with a storage device that stores judgment information for determining whether a voice instructs the execution of the preservation process, and the processing unit determines, based on the judgment information, whether the voice input to the second input unit is a voice instructing the execution of the preservation process.

[0016] According to the fruit management device having the above configuration, it is possible to easily determine the voice instructing the execution of the preservation process from among various voices.

[0017] (6) In the fruit management device of (5), if the voice input to the second input unit is not a voice instructing the execution of the preservation process, the processing unit does not start the preservation process and executes a correction process to input a voice through the second input unit. According to the fruit management device having the above configuration, even if a voice instructing the execution of the preservation process is not obtained, it is possible to instruct the worker to input a voice again through the correction process, and the preservation process can be started appropriately by voice.

[0018] (7) The fruit management device according to (6) above includes an output unit that outputs sound, and the processing unit executes, as the correction process, a process of causing the output unit to output sound information prompting the worker to speak about the identification information. With this configuration, if the result of the first verification process is negative, the worker can quickly try again.

[0019] (8) In the fruit management device according to any one of (1) to (7), when the voice input to the second input unit can be converted into identification information, the processing unit can execute a registration process for registering the identification information indicated by the voice in a database. With this configuration, the database for storing identification information is enriched.

[0020] (9) In the fruit management device according to any one of (1) to (8), the identification information is identification information that is ordered in a direction from one side to the other side of a row of trees. With this configuration, an operator can easily manage quality information by taking measurements along the row of trees.

[0021] (10) Any one of the fruit management devices according to (1) to (9) has a location acquisition unit that acquires location information of measurements made by the measuring device, and the processing unit is capable of executing a grouping process that groups correspondence information in which the identification information and the quality information are associated based on the location information. With this configuration, for example, when multiple trees are arranged in a row, the fruit management device can estimate that these trees are arranged in a row and can automatically group the correspondence information of the trees included in the row.

[0022] (11) In the fruit management device of (10), the processing unit can execute the grouping process by assigning row identification information indicating a row to the correspondence information regarding the trees where the measurement positions are aligned in one direction. With this configuration, when multiple trees are arranged in a row, row identification information is assigned to these trees. This makes it possible to manage trees by row (group).

[0023] (12) In any one of the fruit management devices (1) to (11), the processing unit is capable of executing a second storage process for storing additional information of one or both of the fruit and the tree in association with the correspondence information in which the identification information and the quality information are associated. For example, image information of the tree may be associated with the correspondence information as the additional information, or information indicating the appearance, taste, or other condition of the fruit may be associated with the correspondence information as the additional information.

[0024] (13) In the fruit management device according to any one of (1) to (12), the processing unit is capable of executing an output process for outputting measurement task information indicating a measurement task of the fruit using the measuring device. With this configuration, the fruit management device can guide an operator to prevent mistakes in measurement procedures or missing measurements.

[0025] (14) In the fruit management device of (13), the processing unit executes the output process of outputting, as the measurement task information, information on target trees that bear fruit that needs to be measured. In this case, the worker can measure the trees that bear fruit that needs to be measured in order, making the work easier.

[0026] (15) The fruit management device of (14) has a position acquisition unit that acquires position information of measurements made by the measuring device, and the processing unit is capable of executing a second matching process that compares the position information acquired by the position acquisition unit with a database that stores tree position information in advance, and the processing unit executes, as the second matching process, a process of comparing the position information of the target tree acquired by the position acquisition unit with the position information stored in the database for the target tree indicated by the measurement task information. With this configuration, it is possible for an operator to perform measurement work on the target tree indicated by the measurement task information without error.

[0027] (16) In the fruit management device of (15), the processing unit starts the storage process when the result of the second comparison process is positive. With this configuration, the quality information of the fruit belonging to the target tree indicated by the measurement task information is stored in correct correspondence with the identification information of the target tree.

[0028] (17) In the fruit management device of (15) or (16), if the result of the second comparison process is negative, the processing unit executes a correction process to input voice through the second input unit without starting the saving process. If the tree measured by the measuring device is not the target tree indicated by the measurement task information, the result of the second comparison process is negative. Therefore, with this configuration, the worker is given another opportunity to measure using the measuring device. Quality control errors are prevented. As the correction process, the processing unit executes a process to output a sound from the output unit to prompt the worker to measure using the measuring device (try again).

[0029] (18) In the fruit management device according to any one of (1) to (17), the fruit is grapes. In a farm, grape trees are often arranged in rows. The fruit management device is particularly suitable for managing quality information about such grapes.

[0030] (19) A fruit management system according to the present embodiment includes the fruit management device according to any one of (1) to (18) above, and a measuring unit capable of transmitting the quality information to the fruit management device. The fruit management system according to the present disclosure improves the workability of fruit quality management.

[0031] (20) The computer program of this embodiment is a computer program for operating a computer as a fruit management device that performs information processing to manage quality information of fruits using identification information regarding one or both of fruits and trees that bear fruit, and causes the computer to perform a first input step of acquiring the quality information measured by a measuring instrument, a second input step of acquiring voice as input, and a storage processing step of executing the storage processing if the input voice is voice instructing the execution of a storage processing to save the quality information.

[0032] According to the computer program having the above configuration, the identification information and the quality information obtained by the measuring device are stored in association with each other in a storage process step. The storage process step can be executed by the operator's voice (vocalization) acquired by the second input unit. This eliminates the need for manual input by the operator, improving the workability of fruit quality control.

[0033] <Details of Embodiments of the Present Disclosure> Details of embodiments of the present disclosure will be described below with reference to the drawings. Note that at least some of the embodiments described below may be combined in any manner. [Management System] FIG. 1 is an explanatory diagram of a management system including a fruit management device. The management system 7 shown in FIG. 1 is a system for managing the quality of fruits grown in a field such as a farm. In this embodiment, the fruits are grapes, but other fruits may also be used. Grapes are used, for example, in wine production. The management system 7 (fruit management system) shown in FIG. 1 includes a fruit management device 10 (hereinafter referred to as the "management device 10") and a measuring device 11. Note that the management system 7 may also include a server device 12 in addition to the management device 10 and the measuring device 11. Workers at the farm carry the management device 10, which is a mobile terminal device, and the measuring device 11 to perform measurement work. The management device 10 is a device for managing grape quality information, and for this management, uses identification information that identifies one or both of the grapes and the grape-bearing trees. Specifically, the identification information is one or both of identification information for a cluster of grapes and identification information for a tree having multiple clusters of grapes. The identification information is, for example, information indicating an identification number (identification ID) composed of alphabets and / or numbers. The identification information may also be information for management purposes other than the identification number.

[0034] In a grape farm, grape trees are lined up in rows. In this embodiment, the identification information is assigned in a sequence from one side of the row of trees to the other. The identification information of the trees is assigned in a sequence from one side of the row of trees to the other, and the identification information of the grapes on each tree is assigned a number in order, starting from the lowest cluster at the tip of the branch. By performing measurements along the row of trees, workers can easily acquire and manage quality information. The management device 10 of this embodiment is particularly suitable for managing quality information about grape trees lined up in rows. Note that in the above-described embodiment, the identification information is assigned in a sequence from one side of the row of trees to the other, but the identification information does not have to be assigned in a sequence from one side of the row of trees to the other.

[0035] The management device 10, which is a mobile terminal device, is a portable computer having a processor (arithmetic processing unit) and semiconductor memory consisting of RAM, ROM, etc. A computer program for managing quality information is installed on the computer. The processor reads and executes the computer program from the memory. This allows the mobile terminal device to function as the management device 10 that executes each process for grape quality control. The mobile terminal device may be a smartphone, tablet, or the like.

[0036] The management device 10 has a wireless communication function and can be connected to a communication network 13. The management device 10 can communicate with a server device 12 through the network 13. The server device 12 is, for example, a computer installed in a management facility of a farm. The server device 12 has a control unit 31, a memory unit 32, and a communication unit 33. The control unit 31 is composed of one or more computers, and is connected to the memory unit 32 and the communication unit 33 via an internal bus. The memory unit 32 is composed of a hard disk, a semiconductor memory, or the like. The communication unit 33 is a communication interface for communicating with the management device 10 through the network 13.

[0037] The measuring instrument 11 is a device for measuring the quality of grapes. For example, the measuring instrument 11 irradiates grapes with measurement light, receives transmitted or reflected light, and performs component analysis using spectroscopic analysis. The measuring instrument 11 is capable of non-destructively measuring quality such as sugar content, acidity (total organic acid content), and damage level. The measuring instrument 11 is portable, and an operator carries the management device 10 and the measuring instrument 11 to perform quality measurement work. The measuring instrument 11 has a housing 41 with a computing device that processes component analysis, a measuring unit (measuring head) 42 that irradiates and receives measurement light, and a cable 43 extending from the housing 41 to the measuring unit 42. The operator holds the measuring unit 42 and performs measurement work. The measuring instrument 11 is, for example, a Fruit Selector (trademark, manufactured by Kubota Corporation, K-BA800).

[0038] The measuring instrument 11 has an analysis processing unit 45 and a communication unit 44. The analysis processing unit 45 is configured with a microcomputer having a processor (arithmetic processing unit) and semiconductor memory consisting of RAM, ROM, etc. The measurement unit 42 irradiates the grapes with measurement light and receives the transmitted or reflected light. The analysis processing unit 45 acquires the light reception signal from the measurement unit 42 and performs component analysis. The communication unit 44 has a function for communicating with the management device 10. This communication may be wired or wireless. Quality information, which is the result of the analysis processing by the analysis processing unit 45, is sent to the management device 10.

[0039] [Management Device 10] Figure 2 is a block diagram of the management device 10. The management device 10 has a processing unit 21 that executes information processing for managing grape quality information. The processing unit 21 is composed of a processor (arithmetic processing device) included in a mobile terminal device such as a smartphone or a tablet terminal. The processing unit 21 executes a computer program, thereby performing each process.

[0040] The computer program is a computer program for operating a computer as a management device 10 that performs information processing to manage grape quality information using identification information regarding one or both of the grapes and the trees on which the grapes grow.

[0041] The management device 10 has a memory unit 20. The memory unit 20 is configured with a hard disk, semiconductor memory, or the like. The memory unit 20 stores computer programs executed by the processing unit 21 and other information. The management device 10 has a first input unit and a second input unit. The first input unit is an input interface 23. The input interface 23 is capable of communicating with the measuring device 11 wirelessly or via a cable. The input interface 23 acquires quality information measured by the measuring device 11.

[0042] The second input unit is a microphone 24. The microphone 24 acquires the voice uttered by the worker as input. For example, the microphone 24 acquires the voice uttered by the worker as input so that the management device 10 can acquire identification information. The voice signal is processed by the processing unit 21 and converted into data. The management device 10 may have a display 22 and a position acquisition unit 26. The display 22 is a display device of the mobile terminal device (management device 10) (see FIG. 1). The display 22 displays various data as text information. The display 22 functions as a touch panel and allows the worker to input information through input operations.

[0043] The position acquisition unit 26 is a positioning device that acquires the position of the management device 10. Because workers carry the management device 10 and perform quality measurement work near trees, the position acquisition unit 26 can acquire the work position, i.e., the tree's position information. In this embodiment, the position acquisition unit 26 performs positioning using RTK-GNSS. The position acquisition unit 26 includes an RTK receiver 26a, a GNSS receiver 26b, and a processing circuit 26c. The GNSS receiver 26b receives satellite signals transmitted from multiple GNSS satellites and generates GNSS data based on the satellite signals. In the case of RTK-GNSS, correction signals transmitted from a reference station are used in addition to satellite signals from multiple GNSS satellites. The reference station is installed near the grapevine orchard where the worker performs measurement work. The reference station generates correction signals, for example, in RTCM format, based on the satellite signals from multiple GNSS satellites. The RTK receiver 26a acquires the correction signals. The processing circuit 26c uses the correction signal to correct the positioning result of the GNSS receiver 26b. By using the RTK-GNSS, positioning with an accuracy of, for example, a few centimeters is possible.

[0044] The management device 10 may have an output unit 25, a camera 28, and a communication unit 29. The output unit 25 is a speaker. The speaker 25 outputs various types of information as sound. The processing unit 21 etc. generates various types of information, and the speaker 25 outputs the information as a sound signal. For example, the speaker 25 can output the identification information generated by the generation unit 27 as sound.

[0045] The camera 28 is a photographing device mounted on the management device 10 and is capable of capturing images of grapes or trees. The communication unit 29 is a communication interface for communicating with the server device 12 via the network 13.

[0046] [Specific Example of Quality Control Processing] A description will now be given of the quality control processing performed by the management device 10 having the above configuration and the management system 7 having the management device 10. Figures 3 to 12 are explanatory diagrams of images displayed on the display 22 of the management device 10. The display of images on the display 22 is performed by the function of the processing unit 21. The quality control processing is performed by the processing unit 21. Figure 13 is a flow diagram of the quality control processing.

[0047] [Setting Process] As shown in FIG. 13 , when an operator or the like performs a predetermined operation on the management device 10, the management device 10 starts the quality control process. In the quality control process, the management device 10 first executes a field selection process ST10. In the field selection process ST10, the management device 10 displays a selection screen (farm selection screen) as shown in FIG. 3 on the display 22. The farm selection screen displays information indicating farms, such as farm 1 and farm 2. If multiple farms are displayed on the farm selection screen, at least one farm is available for acceptance. When the operator selects at least one farm from the multiple farms displayed on the farm selection screen by touch operation or the like, the management device 10 determines the selected farm as the farm (variety) where work will be performed. Note that farms are associated with grape varieties. Information on the farms and varieties may be stored in the memory unit 20 of the management device 10 or in the memory unit 32 of the server device 12. In this embodiment, the management device 10 receives the information from the server device 12 and displays a farm selection screen.

[0048] As shown in FIG. 13 , the management device 10 executes the initiation process ST20 after the field selection process ST10. In the initiation process ST20, the management device 10 displays an image on the display 22 prompting the user to check the power supply of the measuring device 11, as shown in FIG. 4 . When a section on the screen of FIG. 4 that asks the user to check that the power supply of the measuring device 11 is turned on is selected, the management device 10 completes the initiation process ST20 and proceeds to the measuring device selection process ST30. In the measuring device selection process ST30, the management device 10 displays, for example, a selection image of the measuring device 11 on the display 22, as shown in FIG. 5 . The management device 10 displays, for example, a selection image of the measuring device 11 connectable to the management device 10 on the display 22. When a specific measuring device 11 is selected from the measuring devices 11 displayed on the display 22, the management device 10 establishes a communication connection with the selected measuring device 11. When the communication connection is successfully established, the management device 10 proceeds to the task selection process ST40 and the positioning selection process ST50, as shown in FIGS. 13 and 6 .

[0049] In the task selection process ST40 and the positioning selection process ST50, the management device 10 displays a management method selection image as shown in FIG. 6 . The selection image in FIG. 6 is an image for selecting whether tree management is required, whether RTK positioning is required (whether positioning by RTK-GNSS is required), and whether bunch (grape) management is required. That is, as shown in FIG. 6 , in the task selection process ST40, it is determined whether tree-by-tree management is required or whether bunch (grape) management is required (whether bunch management is required). As shown in FIG. 6 , in the positioning selection process ST50, it is determined whether RTK positioning is required. If RTK positioning is selected in the positioning selection process ST50, the management device 10 displays a selection image of the RTK device that is the reference station as shown in FIG. 7 . When the operator selects "Start" in the selection image, positioning by RTK-GNSS can be performed.

[0050] As described above, once the operator selects whether or not to manage trees, clusters, and RTK positioning, the management device 10 proceeds to the setting confirmation process ST60, as shown in FIGS. 13 and 8. FIG. 8 shows a setting confirmation screen, in which the items set (selected) in each of the above processes (field selection process ST10, start process ST20, measuring device selection process ST30, task selection process ST40, and positioning selection process ST50) are displayed for confirmation. If there are any errors or corrections, they can be changed from this setting confirmation screen (setting confirmation process ST60). After completing the confirmation, the operator selects "Start" on the setting confirmation screen. The management device 10 then ends the setting process and proceeds to the measurement input process.

[0051] [Measurement Input Process] As shown in Figure 13, the measurement input process includes an input process ST70, an editing process ST80, and a termination process ST90. In the input process ST70, it is possible to input a bunch number (bunch ID), which is identification information for the grapes to be measured. Alternatively, in the input process ST70, it is possible to input, in addition to the bunch number, a tree number (tree ID), which is identification information for the tree on which the grapes with that bunch number grow. In addition to this, it is possible to input quality information from the measuring device 11 in the input process ST70. In other words, in the input process ST70, quality information and identification information for either or both of the grapes (bunch) for which the quality information was obtained and the tree on which the grapes grow are input.

[0052] Specifically, when an operator uses the measuring device 11 to measure the quality of grapes, the management device 10 (processing unit 21) acquires the quality information each time the measuring device 11 acquires the quality information. The management device 10 (processing unit 21) also acquires voice input to the second input unit (microphone 24). If the acquired voice (input voice) can be converted into grape identification information (cluster ID, tree ID), the management device 10 (processing unit 21) converts the input voice into the identification information. If the input voice is a voice (execution voice) instructing execution of a storage process to save the quality information, the management device 10 (processing unit 21) executes the storage process. As the storage process, the management device 10 (processing unit 21) executes a process of linking the quality information input to the input interface (first input unit) 23 with the identification information input to the second input unit (microphone 24) and storing the linked information in the memory unit (storage device) 20 or the like. In other words, in the input step ST70, when the management device 10 (processing unit 21) acquires a voice (execution voice) instructing execution of a storage process, the quality information and the identification information are stored.

[0053] Here, in the input process ST70, whether the voice uttered by the worker is a voice instructing execution of the save process (execution voice) is determined based on the determination information stored in the storage unit (storage device) 20. The determination information is information for determining whether the input voice is an execution voice, and is voice data or a program or data for analyzing voice. FIG. 19 shows an example of the determination information. As shown in FIG. 19 , when "yes" is recognized as the execution voice, if the input voice is "yes" (when the worker says "yes"), the management device 10 (processing unit 21) determines that the execution voice has been acquired. On the other hand, if the input voice is other than "yes" (when the worker says something other than "yes"), the management device 10 (processing unit 21) determines that the execution voice has not been acquired. In other words, when "yes" is recognized as the execution voice, if the voice input to the second input unit (input voice) is "yes," the processing unit 21 determines that the voice instructing execution of the save process is a voice instructing execution of the save process, and if the voice input to the second input unit (input voice) is other than "yes," the processing unit 21 determines that the voice is not a voice instructing execution of the save process. As shown in FIG. 19 , when identification information is recognized as an execution voice, if the input voice corresponds to "identification information" (i.e., the worker utters identification information), the management device 10 (processing unit 21) determines that the execution voice has been acquired. Furthermore, if the input voice is not a voice corresponding to identification information (i.e., the worker utters something other than identification information), the management device 10 (processing unit 21) determines that the execution voice has not been acquired. In other words, when identification information is recognized as an execution voice, if the voice input to the second input unit (input voice) is identification information, the processing unit 21 determines that the voice instructs execution of a storage process to save quality information. If the voice input to the second input unit (input voice) is not identification information, the processing unit 21 determines that the voice instructs execution of a storage process. Whether the execution voice is "yes" or identification information is built into the management device 10 as a program. Whether the execution voice is "yes" or identification information may be set by operating the management device 10.In the above-described embodiment, "Yes" or identification information (a voice corresponding to the identification information) is set as the execution voice, but other voices may also be used and the present invention is not limited to the above embodiment. In the storage process, the management device 10 (processing unit 21) associates the quality information input to the input interface (first input unit) 23 with the identification information input to the second input unit (microphone 24), and stores the associated information in the storage unit (storage device) 20 or the like. The quality information and the identification information may be stored in a database provided in the server device 12. The database may be the first database 35 or the second database 36 described below (see FIG. 1).

[0054] Hereinafter, for ease of explanation, information that associates quality information with identification information may be referred to as "corresponding information." The grapes from which quality information is obtained are referred to as "measurement target grapes (measurement target fruits)." The trees on which measurement target grapes grow are referred to as "measurement target trees." Note that quality information may be stored for each measurement target grape, or for each measurement target tree on which measurement target grapes grow. The identification information associated with quality information may be only the identification information of the measurement target grapes, or only the identification information of the measurement target trees, or may be both the identification information of the measurement target grapes and the identification information of the measurement target trees.

[0055] FIG. 9 shows an example of the display on the display 22 in the input step ST70. As shown in FIG. 9, the display 22 displays a map of the farm selected in the field selection step ST10, or a map of a portion of the farm. The measurement position Q acquired by the position acquisition unit 26 is displayed on the map. The display 22 also displays the number of measurements, the record number, the date and time of the measurement, quality information measured by the measuring device 11, and the like. In the example shown in FIG. 9, the quality information is the sugar content and acidity (total organic acid content). FIG. 9 also displays grape identification information (bunch ID, tree ID), etc. Note that while FIG. 9 shows an image for inputting the identification information outside the display 22, this is for illustrative purposes only; in reality, the image for inputting the identification information is displayed on the display 22.

[0056] As described above, once the storage process of linking the quality information and the identification information, i.e., the storage of the correspondence information, is completed, a registration image is displayed on the display 22 as shown in FIG. 10. FIG. 10 shows the registration image. The registration image includes the associated identification information ("B0001" in the illustrated example) and quality information (sugar content value, acidity value), and this identification information and quality information are displayed as text information. The correspondence information is also stored in association with information on the date and time of the measurement operation by the measuring device 11 and information on the measurement location. The date and time information is acquired by the clock function of the management device 10. The measurement location is acquired by the location acquisition unit 26.

[0057] Other information about the grapes or trees being measured can also be input in the registered image. This other information is defined as additional information. As shown in FIG. 10 , detailed information about the grapes being measured, such as "worm damage," "discoloration," and "name of disease (powdery)," can be input as additional information. Taste evaluation information by an operator (experienced worker) can also be input as additional information. For example, this can be input in the "Memo" field shown in FIG. 10 . Images (photographs) of either or both of the grapes and the trees being measured can be input as additional information. The images are acquired by camera 28.

[0058] Thus, in the input process, the management device 10 associates additional information about one or both of the grapes and the grape-bearing trees with the corresponding information, which associates the identification information with the quality information, and stores the associated information. The additional information is manually input by the operator into the display 22. The additional information is associated with the corresponding information and stored in the management device 10 or the server device 12. As shown in FIG. 10 , when the register button displayed on the display 22 is selected, the management device 10 proceeds to the editing process ST80, which is the next step after the input process ST70. FIG. 11 shows an example of the display 22 in the editing process ST80. As shown in FIG. 11 , the next measurement image includes an edit image. When the operator selects edit, editing of various information that has already been registered (saved) can be performed.

[0059] As shown in FIG. 11 , the measurement screen includes a map of the farm or a portion of the farm. The measurement position Q acquired by the position acquisition unit 26 of the management device 10 is displayed on the map. Furthermore, if the input of the measurement results, etc., has failed, the measurement position E where the measurement failed is displayed on the planar image. As shown in FIG. 11 , when the operator selects "Complete" (the "Complete" button) displayed on the display 22, a measurement completion image is displayed (completion step ST90). FIG. 12 shows the completion image. When "Complete" included in the completion image is selected (if "Yes" is selected for the completion step in FIG. 13 ), the measurement is completed. Until "Complete" is selected (if "No" is selected for the completion step in FIG. 13 ), the process is repeated, starting from the input step (ST70 in FIG. 13 ).

[0060] [Input Process] Figure 14 is a flow diagram (operational flow) of the input process. In the explanation of the operational flow in Figure 14, the explanation will proceed assuming that the execution voice is set to grape identification information (bunch ID, tree ID) or "yes." When the worker speaks (ST901 in Figure 14), the microphone 24 and processing unit 21 of the management device 10 acquire the voice (input voice) and perform voice recognition processing (ST902 in Figure 14).

[0061] In ST902 of FIG. 14 , if the input speech can be converted into identification information, for example, if the speech can be converted into symbols and alphanumeric characters, and the converted data is not words, the processing unit 21 converts the input speech into identification information (identification information data). If the speech can be converted into a string of characters represented by at least symbols and alphanumeric characters, and the string can be distinguished from words, the processing unit 21 determines that the speech can be converted into identification information and converts it into identification information. For example, if the converted speech (converted data) is expressed as "KUBOTA," the processing unit 21 determines that although the converted data is a string, the entire string is a word recognized as a family name and therefore cannot be converted into identification information. On the other hand, if the converted speech (converted data) is expressed as "KUBOTA1221," the processing unit 21 determines that although the converted data is a string, the "1221" portion can be distinguished from words and therefore can be converted into identification information, and executes conversion as identification information. Also, in ST902 of Fig. 14, the processing unit 21 can convert the input voice into identification information (data of identification information) by executing a voice recognition program (voice recognition processing), etc. Also, in ST902 of Fig. 14, even if the input voice is not identification information, the input voice can be converted into data (data other than identification information) by the voice recognition program (voice recognition processing), etc.

[0062] Next, the processing unit 21 determines whether the input voice (converted data) is the execution voice (ST903, ST904 in FIG. 14). The processing unit 21 refers to the determination information stored in the memory unit (storage device) 20 (ST903) and determines whether the execution voice is set to a voice corresponding to the grape identification information (bunch ID, tree ID) (ST904 in FIG. 14).

[0063] Here, if the input voice is identification information and the execution voice is set to a voice corresponding to the identification information (Yes in ST904 of FIG. 14), the identification information is transmitted to server device 12 via communication unit 29 (ST905). Server device 12 then sends a reception confirmation (ST906 of FIG. 14). That is, if the worker utters a voice corresponding to the identification information in ST901 of FIG. 14 and the voice corresponding to the identification information is set as the execution voice, then, via Yes in ST904 of FIG. 14, the identification information is transmitted to server device 12 via communication unit 29 (ST905).

[0064] On the other hand, if the execution voice is not set to a voice corresponding to the grape identification information (bunch ID, tree ID) (No in ST904 of FIG. 14 ), the processing unit 21 determines whether the execution voice is set to a voice corresponding to "yes" (ST907 of FIG. 14 ). If the input voice is "yes" and is the execution voice (Yes in ST907 of FIG. 14 ), the processing unit 21 executes a process to prompt the worker or the like to generate the identification information by voice (ST908 of FIG. 14 ). In ST908 of FIG. 14 , the processing unit 21 executes a process to, for example, display "Please state your identification information" on the display 22 shown in FIG. 9 or generate a sound saying "Please state your identification information" from the speaker 25 of the management device 10.

[0065] When the worker speaks (ST909 in FIG. 14 ), the microphone 24 and processing unit 21 of the management device 10 acquire the voice (input voice) and perform voice recognition processing (ST910 in FIG. 14 ), similar to ST902 in FIG. 14 . The processing unit 21 determines whether the input voice acquired in ST910 in FIG. 14 is grape identification information (bunch ID, tree ID) (ST911 in FIG. 14 ). If the processing unit 21 determines through the voice recognition processing that the input voice is identification information (Yes in ST911 in FIG. 14 ), it transmits the identification information to the server device 12 via the communication unit 29 (ST905). The server device 12 then sends a receipt confirmation (ST906 in FIG. 14 ). In other words, as shown in ST902, ST903, ST904-No, and ST907 to ST911, when the processing unit 21 acquires an execution voice (yes) and a voice (identification information) different from the execution voice, in the storage process, if the voice (identification information) different from the execution voice (yes) can be converted into identification information, the voice (another voice) different from the voice instructing execution is converted into identification information.

[0066] Note that if the input voice generated in ST901 of FIG. 14 is not "Yes" set as the execution voice (No in ST907 of FIG. 14), i.e., if the input voice is not the execution voice (voice instructing execution of a save process to save the quality information), the processing unit 21 proceeds to error processing (correction processing) (ST920 of FIG. 14). In the error processing (correction processing), the processing unit 21 does not start the save process and instead executes correction processing to input voice through the microphone 24. In the correction processing, for example, the processing unit 21 displays "Save process cannot be performed" on the display 22 shown in FIG. 9 or generates a sound saying "Save process cannot be performed" from the speaker 25 of the management device 10. In the correction processing, for example, the processing unit 21 displays "Please state your identification information" on the display 22 shown in FIG. 9 or generates a sound saying "Please state your identification information" from the speaker 25 of the management device 10. Thereafter, the processing unit 21 waits for the worker's voice input, that is, until a voice input is performed, and when the worker speaks (ST901), the processing returns to ST902 and executes the processes from ST902 onwards.

[0067] As shown in ST906 of FIG. 14 , upon receiving a reception confirmation from server device 12, processing unit 21 displays the converted data as text information on display 22. That is, the converted data is used as identification information, and display 22 displays the identification information as text information. By looking at display 22, the worker can confirm that the identification information has been entered correctly (ST912 of FIG. 14 ). In addition to the display on display 22, or instead of displaying the identification information on display 22, output for confirmation of the identification information may be executed from speaker 25. For example, the identification information may be output as a sound from speaker 25.

[0068] The worker uses the measuring device 11 to measure the quality of the grapes corresponding to the identification information (ST913). The management device 10 acquires quality information that is the result of the quality measurement (ST914). The processing unit 21 completes the storage process for storing the quality information in association with the identification information.

[0069] In this embodiment, the correspondence information associating the quality information with the identification information is stored by the server device 12. Therefore, the processing unit 21 executes a storage request process to the server device 12 as a storage process in conjunction with the transmission process of the quality information (ST915 in FIG. 14). Then, the server device 12 stores the correspondence information associating the quality information with the identification information in a database.

[0070] 14, the measuring device 11 measures the quality of the grapes after the identification information is spoken, but the measuring device 11 may measure the quality of the grapes before the information is spoken. If the quality measurement is performed first, the processing unit 21 may execute a save request process to the server device 12 as a save process in conjunction with the process of transmitting the identification information.

[0071] The association between the quality information and the identification information may be performed by the management device 10 or by the server device 12. When the management device 10 performs the association process, it executes a save request process to the server device 12 as the save process in conjunction with the process of transmitting the correspondence information.

[0072] 14 , the microphone 24 acquires the voice uttered by the worker as input in order for the management device 10 to acquire the identification information. The processing unit 21 converts the voice into data that can be processed by the processing unit 21 (conversion process). When the execution voice is input, the processing unit 21 executes a storage process for storing the identification information and quality information in association with each other.

[0073] In this way, the worker vocalizes the identification information in accordance with the grape quality measurement by the measuring device 11. The processing unit 21 performs a conversion process to convert the identification information (voice) into data that can be processed by the processing unit 21. The identification information converted into the data is stored in association with the quality information obtained by the measuring device 11. Note that if the voice input is not successful, the worker can manually input the identification information via the display 22.

[0074] [Another Means for Acquiring Identification Information] Another means for the management device 10 to acquire identification information through voice recognition processing will now be described. In the first means shown in FIG. 14 , the worker vocalizes the identification information, and the management device 10 digitizes (converts to text) the identification information through the conversion process. FIG. 15 is a sequence diagram showing another means (second means) of voice recognition processing. In the second means, the management device 10 generates identification information (ST711) and outputs the identification information as sound (ST712). The worker hears the sound (sound output) and vocalizes approval (ST713), and the speech (voice) is converted into data that can be processed by the processing unit 21 through voice recognition processing (ST714).

[0075] The generation unit 27 of the management device 10 functions for the second means. The generation unit 27 generates identification information (ST711). The generation unit 27 generates the identification information in numerical order, for example, 0001, 0002, 0003, .... The speaker 25 outputs the generated identification information by sound (ST712). For example, the first "0001" is output by sound. In response to the sound output, the worker speaks. Note that instead of the management device 10 generating the identification information (ST711), a list of existing identification information (list information) may be provided to the management device 10, and the identification information may be output by sound according to the list.

[0076] After the speaker 25 outputs "0001," the microphone 24 acquires as input the voice uttered by the worker in response to the sound output (ST713). As described above, after the speaker 25 outputs "0001," the worker hears it and, in response to the sound output, utters a voice indicating that the worker "approves" the identification. For example, the worker utters "OK." The microphone 24 acquires the sound of "OK" as input.

[0077] As a conversion process, the processing unit 21 converts the voice "OK" uttered by the worker into data that can be processed by the processing unit 21. As a result, the processing unit 21 recognizes that the identification information "0001" has been approved (ST714). With the input "OK" from the microphone 24 as a condition, the processing unit 21 executes a process (storage process) for storing the identification information "0001" generated by the generation unit 27 and output as sound by the speaker 25 in association with the quality information.

[0078] The acquisition of quality information in management device 10 (ST716, ST717) and the transmission of information to server device 12 (ST718) are the same as in the first means, and therefore a description thereof will be omitted here. Note that in the second means as well, the measurement of grape quality by measuring device 11 may be performed before or after the utterance of "approval" of the identification information.

[0079] [First Verification Process] In the measurement input step shown in Fig. 13, the processing unit 21 can further execute a first verification process. The first verification process is a process of verifying the identification information acquired by voice recognition with a database 35 that stores identification information in advance, and is executed to correctly associate the quality information with the identification information and store it. The first verification process will be described in the case of the first means (Fig. 14), but the first verification process can also be applied to the second means (Fig. 15).

[0080] For the first collation process, the server device 12 has a database 35 (first database 35) that stores identification information in advance. The database 35 exists in the storage unit 32 (see FIG. 1). Grapes and their trees are already managed for each farm, and the database 35 stores the identification information of these grapes and their trees.

[0081] A number of grapes and / or a number of trees that require quality measurement by an operator are set in advance. This setting is based on "measurement task information." The measurement task information is information that indicates the measurement task (measurement item) for grapes using the measuring instrument 11. The measurement task includes identification information for the grapes, etc., that require quality measurement. The measurement task information is provided to the management device 10 and displayed on the display 22. The operator performs quality measurements of the grapes that require measurement based on this measurement task information. The identification information included in the measurement task information is registered in advance in the database 35.

[0082] 16 is a sequence diagram of a voice recognition process including a first verification process. In a measurement task performed by a worker based on measurement task information, the processing unit 21 acquires data obtained by converting the worker's voice as identification information (ST702), as in the case shown in FIG. 14 . The processing unit 21 then executes a process (first verification process) for verifying the identification information based on the converted data against the database 35. Since the database 35 is provided in the server device 12, the processing unit 21 executes a verification request process to the server device 12 as the first verification process, in conjunction with a process (ST703) for transmitting the identification information based on the converted data.

[0083] The server device 12 compares the identification information acquired from the management device 10 with the identification information registered in the database 35 and determines whether the identification information is registered in the database 35 (ST721). The server device 12 notifies the management device 10 of the comparison result (ST704). If the identification information based on the converted data is registered in the database 35, the result of the first comparison process is positive. If the result of the first comparison process is positive, the storage process is initiated, as in the case shown in FIG. 14. That is, the processing unit 21 executes a storage request process to the server device 12 as a storage process in conjunction with the transmission process of the correspondence information (ST723). The server device 12 then stores the correspondence information, which associates the quality information with the identification information, in the database.

[0084] In this way, when identification information for grapes that require quality measurement is extracted from the identification information registered in database 35, measurements are carried out on the extracted object, and the quality information is stored in correct correspondence with the identification information.

[0085] On the other hand, if the result of the comparison and determination (ST721) is that the identification information based on the converted data is not registered in the database 35, the result of the first comparison process is negative. In this case, the processing unit 21 executes a correction process for inputting voice through the microphone 24 without starting the saving process (ST722). As the correction process, the processing unit 21 executes a process for outputting a sound from the speaker 25 that prompts the worker to speak about the identification information. For example, the speaker 25 outputs a sound saying, "That identification information does not exist. Please try again."

[0086] The microphone 24 enters a voice input standby state, and the worker vocalizes the grape identification information. The microphone 24 of the management device 10 captures the voice (ST701). The processing unit 21 again converts the voice and acquires the data as identification information (ST702). The processing unit 21 then executes a process (first verification process) to verify the identification information based on the converted data against the database 35. The measurement input process, which includes the first verification process, provides the worker with another opportunity to vocalize the identification information. As a result, quality control errors are prevented. If the result of the first verification process is negative, the worker can quickly try again.

[0087] [Registration Process] The management device 10 has a function for adding new identification information to the database 35. When new grapes and trees are set as the subject of quality control, it is possible to register the new identification information in the database 35. For example, if, as a result of the first comparison process, identification information that is not registered in the database 35 is sent from the management device 10 (ST703 in FIG. 16 ), and the management device 10 receives a negative notification as a result of the comparison and determination (ST721), the processing unit 21 executes a registration process to newly register the identification information in the database 35 (ST723 in FIG. 16 ).

[0088] That is, the processing unit 21 executes a registration process for registering the identification information based on the converted data in the database 35. Since the server device 12 has the database 35, the registration process is a registration request process. By the registration process, it is possible to enrich the database 35.

[0089] [Grouping Process] In the measurement input step shown in Fig. 13, the processing unit 21 can further execute grouping process. The grouping process is a process for grouping multiple pieces of correspondence information that satisfy a predetermined condition. The grouping process will be described in the case of the first means (Fig. 14), but the grouping process can also be applied to the second means (Fig. 15).

[0090] As described above (see FIG. 2 ), management device 10 has a location acquisition unit 26 that acquires location information of measurements taken by measuring device 11. This location information indicates the location of the measurement work, and since the worker carrying management device 10 works near trees, management device 10 uses the acquired location information as tree location information. In the measurement input step, processing unit 21 stores, in server device 12, correspondence information that associates identification information acquired based on the worker's speech with quality information acquired by measuring device 11. The grouping process involves grouping the correspondence information based on the location information.

[0091] The grouping process will be described in detail. In this embodiment, the fruit to be measured for quality is grapes. In farms, grape trees are often grown in rows. FIG. 17 is an explanatory diagram showing rows of trees 50 and the measurement positions Pn (n = 1, 2, 3, ...) of each tree 50 (grape). When the processing unit 21 acquires grape quality information using the measuring instrument 11, it acquires from the position acquisition unit 26 the position information at the time the grape quality measurement was performed.

[0092] After measuring one grapevine 50, the worker moves to the next grapevine 50 and measures thereafter. This process is repeated. In this case, as shown in FIG. 17 , the measurement positions indicated by the position information Pn acquired by the management device 10 form a row aligned in one direction, similar to the row of trees 50 for which measurements were taken. If the row of trees 50 is linear, the measurement positions indicated by the acquired position information will be aligned in a straight line in a planar view of the farm. Therefore, as a grouping process, the processing unit 21 performs a process of assigning row identification information indicating the row to the corresponding information regarding the trees 50 whose measurement positions Pn are aligned in one direction.

[0093] When multiple trees 50 are arranged in a row, the management device 10 can infer that these trees 50 are arranged in a row and can automatically group the corresponding information of the trees 50 included in the row. In the present embodiment, since multiple trees 50 are arranged in a linear row, row identification information is assigned to these trees. As a result, management by row (group) is possible.

[0094] [Measurement Task Information Output Processing] In the measurement input step shown in Fig. 13, the processing unit 21 can execute output processing for outputting measurement task information. The measurement task information is information indicating a grape measurement task using the measuring instrument 11, such as identification information for the grapes to be measured or identification information for the tree. The output processing is executed, for example, before the input step (ST70 in Fig. 13), or every time the input step is performed.

[0095] In this embodiment, the processing unit 21 outputs, as measurement task information, identification information of the target tree, which is a grape-bearing tree that requires measurement. The measurement task information may be output as sound from the speaker 25, as text on the display 22, or as both sound and text.

[0096] The output process allows the worker to be guided by the output information and measure the grape-bearing trees that need to be measured in order, making the work easier. Note that the measurement task information indicating the measurement task may be something other than identification information, and may also be information indicating the work content (work sequence) for the measurement. The output process allows the management device 10 to guide the worker so that they do not make mistakes in the measurement procedure or miss any measurements.

[0097] The following describes how to utilize the output process of measurement task information. To utilize this, the management device 10 has a location acquisition unit 26 that acquires location information of measurements taken by the measuring device 11, as described above (see FIG. 2). Furthermore, the management device 10 can reference a database 36 (second database 36) that stores tree location information in advance. In this embodiment, the database 36 (second database 36) is included in the server device 12. The database 36 (second database 36) may be shared with the first database 35.

[0098] The tree position information stored in database 36 is acquired in advance by agricultural machinery such as a tractor. The agricultural machinery has a camera, a positioning device using RTK-GNSS or the like, LiDAR, etc., and can use these to identify trees and acquire their position information. The acquired tree position information is stored in database 36.

[0099] 13 , as described above, processing unit 21 stores in server device 12 correspondence information that associates identification information acquired based on the worker's speech with quality information acquired by measuring device 11. When acquiring quality information, that is, when measuring quality, processing unit 21 acquires location information of measurement by measuring device 11 from location acquisition unit 26. This location information is information that indicates the work location of the measurement. Because workers carrying management device 10 and measuring device 11 work near trees, processing unit 21 can use the acquired location information as tree location information.

[0100] The processing unit 21 executes a process of comparing the location information acquired by the location acquisition unit 26 with the database 36. This process is the second matching process. The second matching process is a tree matching process that compares the trees on which the grapes whose quality has been measured are grown with the trees registered in the database 36. Figure 18 is a flow diagram of the second matching process. The worker measures the grapes on the trees using the measuring device 11, and the processing unit 21 acquires the quality information that is the measurement result (ST731). In this embodiment, the worker measures the grapes on the trees indicated by the measurement task information. Furthermore, the processing unit 21 acquires the measurement work location, i.e., the location information of the measured trees, using the location acquisition unit 26 (ST732).

[0101] As a second matching process, the processing unit 21 executes a process for matching the tree position information acquired by the position acquisition unit 26 during the measurement with the tree position information stored in the database 36 (ST733). The target tree indicated by the measurement task information is extracted from the trees previously stored in the database 36. Therefore, the matching process is executed for the target tree indicated by the measurement task information among the trees stored in the database 36.

[0102] If the result of the second comparison process is positive (Yes in ST734), the processing unit 21 starts the storage process (ST735). That is, in conjunction with the transmission process of the correspondence information, the processing unit 21 executes a storage request process to the server device 12 as a storage process. The server device 12 then stores the correspondence information, which associates the quality information with the identification information, in the database. As a result, the quality information of the grapes belonging to the target tree indicated by the measurement task information has actually been acquired, and the quality information is stored in correct association with the identification information of the target tree.

[0103] On the other hand, if the worker mistakenly uses the measuring device 11 to measure a tree that is not the target tree indicated by the measurement task information, that is, if the tree actually measured by the measuring device 11 is not the target tree indicated by the measurement task information, the result of the second verification process is negative (No in ST734). If the result of the second verification process is negative, the processing unit 21 executes a correction process to input voice through the microphone 24 without starting the saving process (ST736).

[0104] As the correction process, the processing unit 21 executes a process of outputting sound from the speaker 25 information prompting the worker to measure (try again) using the measuring device 11. The worker is given another opportunity to measure using the measuring device 11. The worker confirms that the target tree indicated by the measurement task information is the one measured again using the measuring device 11. This prevents errors in quality control. In this way, the second verification process allows the worker to measure the target tree indicated by the measurement task information without error.

[0105] [Management Device 10 of the Present Embodiment] As described above, the management device 10 of the present embodiment has a processing unit 21, which performs information processing to manage grape quality information using identification information related to one or both of the grapes (fruit) and the grape-bearing trees. The management device 10 has an input interface (first input unit) 23 that acquires the quality information measured by the measuring instrument 11, and a microphone (second input unit) 24 that acquires as input the voice uttered by the worker to acquire the identification information.

[0106] The processing unit 21 can execute a conversion process to convert the voice into data that can be processed by the processing unit 21, and a storage process (storage process) to store the identification information and quality information in association with each other, using the voice input as a condition (trigger). By this storage process, the identification information and the quality information obtained by the measuring instrument 11 are associated with each other and stored in the server device 12. The storage process is executed using the voice (utterance) of the worker picked up by the microphone 24 as a condition (trigger). This eliminates the need for manual input by the worker, improving the workability of grape quality control.

[0107] In the first method shown in FIG. 14 , the worker vocalizes identification information. The processing unit 21 uses the data converted from the voice as identification information. The processing unit 21 executes, as the storage process, a process for correlating and storing the identification information based on the data with quality information, with the input as a condition. In the first method, the worker vocalizes identification information in conjunction with measuring the quality of grapes with the measuring device 11. The processing unit 21 performs a conversion process and converts the identification information (voice) into the data. The identification information converted into data and the quality information obtained by the measuring device 11 are stored in association with each other.

[0108] 15 , the management device 10 vocalizes the identification information, and the worker approves it. To this end, the generation unit 27 of the management device 10 generates the identification information. The speaker 25 outputs the generated identification information as sound. After the sound is output by the speaker 25, the microphone 24 acquires as input the voice uttered by the worker in response to the sound output by the speaker 25.

[0109] The processing unit 21 executes, as the storage process, a process for storing the identification information generated and output as sound by the generation unit 27 in association with the quality information, using the input of the voice as a condition (trigger). In the second method, the management device 10 (generation unit 27) generates the identification information, and the speaker 25 outputs the identification information as sound. In response to the sound output, the worker vocalizes an utterance indicating that the identification information is "approved." As a conversion process, the processing unit 21 converts the voice uttered by the worker into data that can be processed by the processing unit 21, thereby recognizing that the identification information has been approved. The identification information and the quality information obtained by the measuring instrument 11 are stored in association with each other.

[0110] As described above, by continuing to accumulate corresponding information, it is possible to manage time-series changes in quality for each grape and tree. The time-series changes are displayed on the display 22 or on a display provided in the server device 12.

[0111] The computer program of this embodiment is a computer program that causes a computer (management device 10, which is a mobile terminal device) to execute at least the following steps: First input step: a step of acquiring quality information measured by measuring instrument 11 (ST707 in FIG. 14, ST717 in FIG. 15); Second input step: a step of acquiring voice as input (ST701 in FIG. 14, ST713 in FIG. 15); Conversion processing step: a step of converting the voice into data that can be processed by the computer (ST702 in FIG. 14, ST714 in FIG. 15); Storage processing step: a step of storing identification information and quality information in association with each other, using the voice input as a condition (trigger) (ST708 in FIG. 14, ST718 in FIG. 15).

[0112] [Other] The computer program used in the management device 10 may be manufactured and sold independently of the management device 10 (mobile terminal device). The computer program may be provided, for example, by being stored on a computer-readable storage medium. The computer program may be provided by downloading via a telecommunications line (for example, the Internet).

[0113] In the configuration shown in FIG. 1 , the management device 10 is separate from the measuring device 11. The management device 10 and the measuring device 11 may also be integrated. For example, a computer program for executing the functions of the analysis processing unit 45 of the measuring device 11 is stored in the management device 10, which is a mobile terminal device. The measuring unit 42 is connected to the interface of the management device 10. In this way, the management device 10 may have the functions of the measuring device 11. Alternatively, the measuring device 11 may have the functions of the management device 10.

[0114] The above-described embodiments are illustrative in all respects and are not limiting. The scope of the present invention is defined by the claims rather than the above-described embodiments, and includes all modifications within the scope equivalent to the configurations described in the claims.
