  As shown in FIG. 1, the harvest management system includes a computing device 30. The arithmetic device 30 is, for example, a server or a mobile terminal (smart phone, tablet, PDA, notebook computer, etc.). Further, the arithmetic device 30 may be a device provided in the crop discharge device 40. For example, the calculation device 30 may be combined with the control device 48, or provided in the harvest discharge device 40 separately from the control device 48. Also good. In this embodiment, the calculation device 30 will be described as a mobile terminal.

The portable terminal 30 can be connected to the communication device 16 and can acquire various information from the communication device 16. For example, the mobile terminal 30 receives information (identification information,
(Capacity information, mounting information, radio wave intensity), grain characteristic information, harvest information, and the like can be received. The portable terminal 30 includes a storage unit 31, an estimation unit 32, and a display unit 33.

As shown in FIG. 6, the storage unit 31 stores IDs of a plurality of first RFID tags 10A (tag A, tag B, tag C, tag D) attached to the first container 11A. The storage unit 31 stores IDs of a plurality of second RFID tags 10B (tag E, tag F, tag G, tag H) attached to the second container 11B. The IDs of tag A, tag B, tag C, and tag D are identification information of the first container 11A. The IDs of the tag E, tag F, tag G, and tag H are identification information of the second container 11B. Each of the IDs of tag A to tag D is assigned in advance to correspond to the first container 11A, and even with one ID, the first container 11A can be identified. Each of the IDs of the tags E to H is assigned in advance corresponding to the second container 11B, and even if it is one ID, the second container 11B can be identified. In addition, you may memorize | store the attachment number of the tag attached to the predetermined | prescribed container in the memory | storage part 31 as attachment information.

  The estimation unit 32 estimates the grain discharge destination, and includes a program stored in the mobile terminal 30. The estimation unit 32 estimates the grain discharge destination based on the radio wave intensity of the plurality of RFID tags 10 received by the RFID reader 20. Specifically, the estimation unit 32 discharges the grain based on the radio wave intensity at the plurality of first RFID tags 10A received by the RFID reader 20 and the radio wave intensity at the plurality of second RFID tags 10B received by the RFID reader 20. Estimate the destination. That is, the estimation unit 32 estimates the grain discharge destination based on at least the radio wave intensity of the identification information among the information received by the RFID reader 20. In this case, the plurality of first RFID tags 10A and the plurality of second RFID tags 10B may be tags that output only identification information.

  When estimating the grain discharge destination, the estimation unit 32 uses the radio wave intensities (received radio wave intensities) of the plurality of first RFID tags 10A and the plurality of second RFID tags 10B received by the RFID reader 20 during the discharging operation. In the discharge operation, the discharge unit 49 is located on the container 11 from the start of discharge to the completion of discharge, and the RFID reader 20 can receive the identification information of the second RFID tag 10B.

  First, when a predetermined program or the like of the portable terminal 30 is activated and estimation of the grain discharge destination is started, the estimation unit 32 refers to the storage unit 31 and refers to the number of tags (first number) attached to the first container 11A. 1 attachment number) and the number of tags attached to the second container 11B (second attachment number) are determined to be the same. For example, as shown in FIG. 6, the storage unit 31 stores four first RFID tags 10A (tag A, tag B, tag C, tag D) and the first container 11A in association with each other. . Therefore, the estimation unit 32 recognizes that the first attachment number is four. Similarly, since the four second RFID tags 10B (tag E, tag F, tag G, tag H) are stored in the storage unit 31 in association with each other, the estimation unit 32 has a second attachment number of 4. Recognize that it is an individual. Thus, when the first number of attachments and the second number of attachments are the same, the sum of the radio field intensities (first sum) of all the tags A to D corresponding to the first container 11A, and the second The total of the radio field intensities (second total) of all the tags E to G corresponding to the container 11B is compared. For example, FIG. 7A shows the radio field intensity of a plurality of first RFID tags 10A (tag A, tag B, tag C, tag D) and the plurality of second RFID tags 10B (tag E, tag F, tag G, tag H). An example of radio wave intensity is shown.

  As shown in FIG. 7A, since the first total is larger than the second total, the estimation unit 32 determines the grain discharge destination as the first container 11A. The portable terminal 30 displays the discharge destination estimated by the estimation unit 30 on the display unit 33 configured by a liquid crystal panel or the like. For example, when the first container 11A is “container A” and the second container 11B is “container B”, the display unit 33 displays that the grain discharge destination is “container A”.

  As described above, when the first attachment number and the second attachment number are the same, the estimation unit 32 compares the first sum and the second sum, and determines the larger one as the discharge destination. judge. However, when the first number of attachments and the second number of attachments are different from each other, the first sum and the second sum are corrected from the ratio of the first attachment number and the second attachment number, and the corrected first sum and second Compare the total. For example, when the number of second attachments is greater than the number of first attachments, the first total is “first total = (second attachment number / first attachment number) × the field intensity of the tag attached to the first container. The second sum is obtained as the sum of all the radio field intensities attached to the second container. In addition, the estimation unit 32 compares the first sum and the second sum. Similarly, when the second number of attachments is smaller than the first number of attachments, the first total is obtained by summing up all the radio wave intensities attached to the first container, and “second total = (first attachment number / 2nd number of attachments) × average radio field intensity of tags attached to the second container ”.

Note that the estimation unit 32 compares the first sum and the second sum and determines that the larger numerical value is the discharge destination, but the difference between the first sum and the second sum (difference in radio wave intensity) is determined. If the radio wave intensity difference is greater than or equal to a predetermined value, the larger value may be determined as the discharge destination.
In the embodiment described above, the estimation unit 32 obtains the first attachment number and the second attachment number by referring to the storage unit 31, but instead, the plurality of first RFID tags 10A and the plurality of second RFID tags. The first attachment number and the second attachment number may be obtained based on the attachment number included in the attachment information transmitted from 10B.

  In addition, the estimation unit 32 estimates the discharge destination based on the radio wave intensity. Alternatively, the estimation unit 32 may estimate the discharge destination based on the number of tags that have received the identification information. Specifically, the estimation unit 32 includes the number of first RFID tags 10A (first received number) that the RFID reader 20 has received identification information, and the number of second RFID tags 10B that the RFID reader 20 has received the identification information. Based on the number (second received number), the harvest destination is estimated. FIG. 7B is a diagram illustrating the first reception number and the second reception number. The estimation unit 32 sets the number of identification information (ID) received by the RFID reader 20 among the IDs of the tags A, B, C, and D as the first reception number. The estimation unit 32 sets the number of identification information (ID) received by the RFID reader 20 among the IDs of the tag E, tag F, tag G, and tag H as the second reception number.

The estimation unit 32 compares the first reception number and the second reception number when the first attachment number in the first container 11A and the second attachment number in the second container 11B are the same. As illustrated in FIG. 7B, the estimation unit 32 determines that the discharge destination is “container A” because the first reception number is larger than the second reception number.
When the first attachment number and the second attachment number are different, the estimation unit 32 estimates the discharge destination based on the first reception number and the second reception number and the attachment number stored in the storage unit 31. Specifically, the estimation unit 32 obtains a ratio of the first reception number to the first attachment number (first reception number / first attachment number), and a ratio of the second reception number to the second attachment number (first number). 2 received number / second attached number). Then, the estimation unit 32 compares the ratio of the first reception number with respect to the first attachment number and the ratio of the second reception number with respect to the second attachment number, and discharges the container 11 corresponding to the attachment number with a high ratio. First. For example, when the first attachment number is 5 and the second attachment number is 3, the first reception number is 3 and the second attachment number is 3. In this case, the estimation unit 32 determines that the discharge destination is “container B (second container 11B)”.

  As described above, the container 11 includes a plurality of RFID tags 10 that transmit information related to the container 12 (the container 11). Therefore, information from a plurality of RFID tags 10, for example, identification information of the container 11 can be obtained in one container 11. For example, the identification information transmitted from the plurality of RFID tags 10 can be acquired simply by bringing the RFID reader 20 that receives the identification information of the RFID tag 10 close to the container 11. That is, when the harvest is stored in the container 11, the storage destination of the grain can be easily specified.

The accommodating part 12 has a bottom part 13 and a peripheral part 14 surrounding the bottom part 13, and the plurality of RFID tags 10 are provided in the peripheral part 14. Since a plurality of RFID tags 10 are provided on the peripheral portion 14, information of the container 11 can be easily transmitted from the container 11 to the outside, and the RFID reader 20 receives information from the RFID tag 10 at various positions ( Acquisition).
In addition, the plurality of RFID tags 10 are provided in the vicinity of the portion of the peripheral portion 14 where the opening 15 is formed. In a plurality of RFID tags 10, even if the radio wave is relatively weak, it is easy to make the information of the RFID tag 10 reach the external RFID tag 10, and it is possible to prevent the transmission of radio waves from being hindered by the harvest itself. it can.

  The peripheral portion 14 includes a vertical wall 14a that rises from the bottom portion 13 and a horizontal wall 14b that stands from the bottom portion 13 and intersects the vertical wall 14a. The plurality of RFID tags 10 include one or more RFID tags 10a provided on the vertical wall 14a and one or more RFID tags 10b provided on the horizontal wall 14b. Information of the RFID tag 10 can be transmitted to the outside at least from both the vertical wall 14a side and the horizontal wall 14b side, and the RFID reader 20 can easily acquire the information of the RFID tag 10.

  The RFID tag 10 is a passive tag having a storage unit 101 that stores identification information for identifying the storage unit 12 (the storage container 11), and a transmission unit 102 that transmits the identification information stored in the storage unit 101. Since the RFID tag 10 is composed of passive tags, the range of radio waves transmitted (output) from the plurality of RFID tags 10 is adjusted to the size of the container 11 or from the RFID tag 10 at a predetermined position. It is possible to set a range in which radio waves can be received.

  In addition, the harvest management system includes a plurality of first RFID tags 10A that transmit information related to the first container 11A, a plurality of second RFID tags 10B that transmit information related to the second container 11B, and grains that are used in the first container 11A. And the information received by the RFID reader 20 and the RFID reader 20 provided in the combine 40 that is discharged to one of the second containers 11B and capable of receiving the information of the plurality of first RFID tags 10A and the information of the plurality of second RFID tags 10B. An arithmetic unit 30 is provided that estimates the discharge destination of the grains discharged from the combine 40 based on the above.

When the grain is discharged from the combine 40 to either the first container 11A or the second container 11B, it is simply estimated whether the grain discharge destination is the first container 11A or the second container 11B. Can do.
The portable terminal 30 estimates the grain discharge destination based on the radio field intensity of the plurality of first RFID tags 10A and the radio field intensity of the plurality of second RFID tags 10B received by the RFID reader 20. The grain discharge destination is determined simply by comparing the radio field intensity of the plurality of first RFID tags 10A provided in the first container 11A and the radio field intensity of the plurality of second RFID tags 10B provided in the second container 11B. can do. For example, the one where the radio field intensity of the first RFID tag 10A or the second RFID tag is stronger can be determined as the grain discharge destination.

  Based on the number of first RFID tags 10 </ b> A (first received number) and the number of second RFID tags 10 </ b> B (second received number) that the RFID reader 20 has received information on, the portable terminal 30 discharges grain. Is estimated. Since the number of receptions that can be received by the RFID reader 20 varies depending on the distance between the combine 40 and the container 11, it is possible to determine the grain discharge destination only by comparing the first reception number and the second reception number. it can. For example, among the first reception number and the second reception intensity, the one with the larger reception number can be determined as the grain discharge destination.

  The portable terminal 30 includes a plurality of first RFID tags 10A (number of reception) and a plurality of second RFID tags 10B (number of reception) from which the RFID reader 20 has received information, and a plurality of first RFID tags for the first container 11A. Based on the attachment information of 10A and the attachment information of the plurality of second RFID tags 10B with respect to the second container 11B, the grain discharge destination is estimated. For example, when the number of the first RFID tags 10A attached to the first container 11A is different from the number of the second RFID tags 10B attached to the second container 11B, not only the received number but also the attachment information as supplementary information. By using it, it can be determined as a grain discharge destination.

The RFID reader 20 includes a changing unit 20a that changes the reception sensitivity for receiving radio waves from the RFID tag 10. In other words, the changing unit 20a of the RFID reader 20 can change the radio wave reading intensity from the RFID tag 10. The changing unit 20 a of the RFID reader 20 changes the reception sensitivity when performing calibration with the RFID tag 10.
The portable terminal 30 has a setting unit 35 for performing calibration. Setting part 3
5 includes a program stored in the mobile terminal 30. When the program of the mobile terminal 30 is activated, the setting unit 35 displays on the display unit 33 of the mobile terminal 30 to indicate that it is in the calibration mode. The setting unit 35 displays a start button or the like for starting calibration on the display unit 33. In order to perform calibration, the front end portion (discharge port 49b1) of the lateral feed portion 49b is disposed above the center portion of the predetermined container 11. And if the start button displayed on the display part 33 of the portable terminal 30 is selected in the state which stopped the front-end | tip part (discharge port 49b1) of the horizontal feed part 49b, a calibration will be started. When calibration is started, the RFID reader 20 outputs radio waves and measures the radio field intensity of the RFID tag 10. The changing unit 20a of the RFID reader 20 gradually decreases the reception sensitivity from the maximum value in response to the start of calibration. The setting unit 35 of the portable terminal 30 has a predetermined reception sensitivity when the radio field intensity of all the RFID tags 10 attached to the predetermined container 11 is equal to or higher than a predetermined value (when at least identification information can be received), for example, The display unit 33 displays “Identified”. On the other hand, the setting unit 35 of the mobile terminal 30 has a predetermined reception sensitivity when the radio field intensity of all the RFID tags 10 attached to the predetermined container 11 is less than a predetermined value (when the identification information cannot be received). ), For example, “Unable to identify” is displayed on the display unit 33. The RFID reader 20 stores the reception sensitivity when the radio wave intensity of the RFID tag 10 is equal to or higher than a predetermined value, and holds the reception sensitivity.

In the above-described embodiment, in the calibration mode, it is determined whether the radio wave intensity of the RFID tag 10 is equal to or higher than the predetermined value while changing the reception sensitivity. The receiving destination of the grain may be estimated by changing the reception sensitivity.
Hereinafter, the grain discharge destination may be estimated in a state where the reception sensitivity can be changed. FIG. 8 shows an estimated display screen Q1 in which the reception sensitivity can be changed and the grain discharge destination can be displayed. In FIG. 8, the estimation unit 32 will be described taking an example of estimating the grain discharge destination based on the radio wave intensity. However, the estimation of the discharge destination is not limited to the radio wave intensity, and all the methods described above are adopted. Can do.

  The estimation unit 32 displays an estimation display screen Q1 indicating the estimation of the container on the display unit 33 of the mobile terminal 30. For example, the estimation unit 32 displays the first container 11A and the second container 11B on the estimation display screen Q1. The estimation unit 32 displays the first RFID tag 10A (tag A, tag B, tag C, tag D) attached to the first container 11A on the estimation display screen Q1. The estimation unit 32 displays the second RFID tag 10B (tag E, tag F, tag G, tag H) attached to the second container 11B on the estimation display screen Q1. The estimation unit 32 displays an estimation start button 36 on the estimation display screen Q1. The estimation unit 32 displays a scale unit 37 from the upper limit to the lower limit of the reception sensitivity of the RFID reader 20 and a designation unit 38 for designating the reception sensitivity on the estimation display screen Q1. The designation unit 38 is movable along the scale unit 37, and the reception sensitivity can be changed by moving the designation unit 38. When the estimation start button 36 displayed on the estimation display screen Q1 is selected, the RFID reader 20 outputs radio waves and measures the radio wave intensity of the RFID tag 10. On the estimated display screen Q1, the radio field intensity of the first RFID tag 10A and the second RFID tag 10B obtained by the estimating unit 32 is displayed. Further, the sum of the radio field intensities of all the tags A to D corresponding to the first container 11A (first sum) and the sum of the radio field intensities of all the tags E to G corresponding to the second container 11B (the first sum). 2 sum), the radio field intensity difference between the first sum and the second sum is displayed. Further, the container 11 estimated by the estimation unit 32 of the mobile terminal 30 is displayed. Here, when the radio field intensity difference is less than a predetermined value (determination threshold) and the estimation unit 32 cannot determine the container 11 (determination of the discharge destination), it indicates that the discharge destination cannot be estimated. The notification information is displayed on the estimated display screen Q1 of the portable terminal 30.

As described above, the RFID reader 20 can adjust the reception sensitivity of the plurality of first RFID tags 10A and the plurality of second RFID tags 10B. The size of the container 11, the arrangement of the containers 11, the mounting interval of the first RFID tag 10A with respect to the container 11A, the mounting interval of the second RFID tag 10B with respect to the second container 11B, etc. By adjusting the reception sensitivity in response to various situations, it is possible to properly grasp the grain discharge destination. For example, when the first container 11A and the second container 11B are very small and the first RFID tag 10A and the second RFID tag 10B are adjacent to each other, the reception state of both is changed by reducing the reception sensitivity. For example, the difference in radio field intensity can be increased.

  If the grain discharge destination cannot be estimated, the portable terminal 30 outputs notification information indicating that the discharge destination cannot be estimated. An operator or the like can grasp that the discharge destination cannot be estimated regardless of whether the calibration or the discharge operation is in progress. Actions can be taken when the destination cannot be estimated. For example, it is possible to change the grain discharge position (the position of the discharge port 49b1 with respect to the container 11) from the current position to another position and try again to estimate the discharge destination. It is possible to carry out the discharge operation while making it possible to estimate.

The display unit 33 displays the notification information or the estimated discharge destination. Therefore, the operator can grasp that the discharge destination cannot be estimated only by looking at the display unit 33, or can confirm the discharge destination determined by the estimation unit 31.

The receiving device 81 is a device that can receive the radio wave of the first device 80A and the radio wave of the second device 80B. The receiving device 81 is provided in the harvesting device 40 such as a combine. The mounting structure of the receiving device 81 is the same as that of the RFID reader 20 in the first embodiment, and a description thereof will be omitted.

  The computing device 82 is, for example, a device provided separately from the harvesting device 40 and is a [server, portable terminal (smart phone, tablet, PDA, notebook computer, etc.)]. In this embodiment, the computing device 82 is a mobile terminal. The portable terminal 82 can be connected to the communication device 16 and can acquire various information from the communication device 16. For example, the mobile terminal 82 can receive information (identification information, capacity information, mounting information, radio wave intensity), grain characteristic information, harvest information, and the like received by the first device 80A and the second device 80B.

  The mobile terminal 82 includes a storage unit 83, an estimation unit 84, and a display unit 85.

The computing device 82 estimates the grain discharge destination based on the radio wave intensity of the first device 80A received by the receiving device 81 and the radio wave intensity of the second device 80B received by the receiving device 81.

  In the portable terminal 82 (estimating unit 84), the estimation of the grain discharge destination in the radio wave intensity is the same as the method shown in the first embodiment. That is, the first RFID tag 10A shown in the first embodiment is read as “first device 80A”, the second RFID tag 10B is read as “second device 80B”, and the RFID reader 20 is read as “receiving device 81”. A, tag B, tag C, and tag D are read as “device A, device B, device C, device D”, and tag E, tag F, tag G, and tag H are replaced with “device E, device F, device G, device” It should be read as “H”, the estimation unit 32 as “estimation unit 84”, the storage unit 31 as “storage unit 83”, and the display unit 33 as “display unit 85”. As described above, even if the first container 80A provided in the first container 11A is not plural but one, the second apparatus 80B provided in the second container 11B is not plural but one. Even so, the estimation unit 84 estimates the discharge destination based on the radio wave intensity.

  The mobile terminal 82 (estimator 84) may estimate the grain discharge destination based on the presence of the radio wave of the first device 80A and the radio wave of the second device 80B received by the receiving device 81. The estimation of the discharge destination based on the presence or absence of radio waves in the portable terminal 82 (estimator 84) is the same as the method shown in the first embodiment. That is, depending on the presence or absence of radio waves received by the receiving device 81, the estimation unit 84 determines the number of first devices 80A (first received number) that the receiving device 84 has received identification information and the number of second devices 80B.

The grain discharge destination can be determined only by comparing the radio field intensity of the plurality of first devices 80A provided in the first container 11A and the second device 80B provided in the second container 11B. The stronger radio wave intensity of the first device 80A or the second device 80B can be determined as the grain discharge destination.

  The portable terminal 82 estimates the grain discharge destination based on the presence / absence of the radio wave of the first device 80A and the radio wave of the second device 80B received by the receiving device 81. Since the number of devices that can be received by the receiving device 81 varies depending on the distance between the combine 40 and the container 11, the first received number of the plurality of first devices 80A and the second received number of the plurality of second devices 80B Thus, it can be easily determined as a grain discharge destination.

  The mobile terminal 82 receives the radio wave of the first device 80A and the radio wave of the second device 80B received by the receiving device 81, the attachment information of the first device 80A with respect to the first container 11A, and the second information with respect to the second container 11B. Based on the attachment information of the device 80B, the grain discharge destination is estimated. For example, when the number of the first devices 80A attached to the first container 11A is different from the number of the second devices 80B attached to the second container 11B, not only the received number but also the attachment information as supplementary information. By using it, it can be determined as a grain discharge destination.

  The receiving device 81 can adjust the radio wave reception sensitivity of the first device 80A and the second device 80B. An operator or the like can grasp that the discharge destination cannot be estimated regardless of whether the calibration or the discharge operation is in progress. Actions can be taken when the destination cannot be estimated. For example, it is possible to change the grain discharge position (the position of the discharge port 49b1 with respect to the container 11) from the current position to another position and try again to estimate the discharge destination. It is possible to carry out the discharge operation while making it possible to estimate.
