The estimation unit 32 estimates the discharge destination of the grain, and is composed of a program or the like stored in the mobile terminal 30. The estimation unit 32 estimates the grain discharge destination based on the radio field intensities of the plurality of RFID tags 10 received by the RFID reader 20. Specifically, the estimation unit 32 discharges grains based on the radio field strength of the plurality of first RFID tags 10A received by the RFID reader 20 and the radio field strength of 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 strength (received radio wave strength) of the plurality of first RFID tags 10A and the plurality of second RFID tags 10B received by the RFID reader 20 during the discharge work. In the discharge work, 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 mobile terminal 30 is activated and the estimation of the grain discharge destination is started, the estimation unit 32 refers to the storage unit 31 and the number of tags attached to the first container 11A (the first). It is determined whether or not the number of tags attached to the second container 11B (the number of attached pieces) is the same as the number of tags attached to the second container 11B. For example, as shown in FIG. 6, four first RFID tags 10A (tag A, tag B, tag C, tag D) and the first container 11A are stored in association with each other in the storage unit 31. .. Therefore, the estimation unit 32 recognizes that the number of first attachments is four. Similarly, since four second RFID tags 10B (tag E, tag F, tag G, tag H) are stored in association with each other in the storage unit 31, the number of second attachments of the estimation unit 32 is four. Recognize that it is an individual. In this way, when the number of first attachments and the number of second attachments are the same, the sum of the radio field intensities of all tags A to D corresponding to the first accommodator 11A (first total) and the second Compare with the sum (second sum) of the radio field strengths of all tags E to G corresponding to the incubator 11B. For example, FIG. 7A shows the radio field intensities of the 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 field strength 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 to the first container 11A. The mobile terminal 30 displays the discharge destination estimated by the estimation unit 30 on the display unit 33 composed of 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 "container A" as the grain discharge destination.

As described above, when the first mounting number and the second mounting number are the same, the estimation unit 32 compares the first total and the second total, and sets the larger numerical value as the discharge destination. judge. However, when the first mounting number and the second mounting number are different from each other, the first total and the second total are corrected from the ratio of the first mounting number and the second mounting number, and the corrected first total and second total are corrected. Compare with the total. For example, when the number of second attachments is larger than the number of first attachments, the first total is "first total = (second attachment number / first attachment number) x radio field strength of the tag attached to the first container. The second total is calculated by the sum of all the radio field strengths attached to the second container. Then, the estimation unit 32 compares the first total with the second total. Similarly, when the number of the second mounting is smaller than the number of the first mounting, the first total is calculated by the sum of all the radio field strengths mounted in the first container, and "second total = (first mounting number /). 2nd number of attachments) x average radio field strength of tags attached to the 2nd container ”.

In addition, the estimation unit 32 compared the first total and the second total, and determined the one with the larger numerical value as the discharge destination, but the difference between the first total and the second total (radio wave intensity difference). If the difference in radio field intensity is greater than or equal to a predetermined value, the larger value may be determined as the emission destination.
In the above-described embodiment, the estimation unit 32 has determined the number of first attachments and the number of second attachments by referring to the storage unit 31, but instead of this, the plurality of first RFID tags 10A and the plurality of second RFID tags The first mounting number and the second mounting number may be obtained based on the mounting number included in the mounting information transmitted from 10B.

Further, the estimation unit 32 estimates the emission destination based on the radio wave intensity, but instead of this, the estimation unit 32 may estimate the emission destination based on the number of tags that have received the identification information. Specifically, the estimation unit 32 includes the number of the plurality of first RFID tags 10A (the number of first receptions) for which the RFID reader 20 has received the identification information, and the plurality of second RFID tags 10B for which the RFID reader 20 has received the identification information. The discharge destination of the harvested product is estimated based on the number (second received number). FIG. 7B is a diagram showing a first reception number and a second reception number. The estimation unit 32 uses the number of identification information (IDs) that can be received by the RFID reader 20 among the IDs of the tags A, B, tag C, and tag D as the first received number. The estimation unit 32 uses the number of identification information (IDs) that can be received by the RFID reader 20 among the IDs of the tags E, F, tag G, and tag H as the second reception number.

When the first mounted number in the first container 11A and the second mounted number in the second container 11B are the same, the estimation unit 32 compares the first received number and the second received number. As shown in FIG. 7B, the estimation unit 32 determines that the discharge destination is "container A" because the number of first receptions is larger than the number of second receptions.
When the number of first attachments and the number of second attachments are different, the estimation unit 32 estimates the discharge destination based on the number of first receptions and the number of second receptions and the number of attachments stored in the storage unit 31. Specifically, the estimation unit 32 obtains the ratio of the first received number to the first mounted number (first received number / first mounted number), and the ratio of the second received number to the second mounted number (first). 2 Received number / 2nd mounting number). Then, the estimation unit 32 compares the ratio of the first received number to the first mounted number and the ratio of the second received number to the second mounted number, and discharges the container 11 corresponding to the mounted number having a high ratio. First. For example, when the number of first attachments is 5 and the number of second attachments is 3, the number of first receptions is 3 and the number of second attachments is 3. In this case, the estimation unit 32 determines that the discharge destination is the “container B (second container 11B””.

According to the above, the container 11 includes a plurality of RFID tags 10 for transmitting information about the storage unit 12 (container 11). Therefore, in one container 11, information from a plurality of RFID tags 10, for example, identification information of the container 11 can be obtained. For example, the identification information transmitted from the plurality of RFID tags 10 can be obtained only 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 harvested product is stored in the container 11, the storage destination of the grain can be easily specified.

The accommodating portion 12 has a bottom portion 13 and a peripheral portion 14 surrounding the bottom portion 13, and a plurality of RFID tags 10 are provided on the peripheral portion 14. Since a plurality of RFID tags 10 are provided on the peripheral portion 14, the information of the containment device 11 can be easily transmitted from the container 11 to the outside, and the RFID reader 20 receives the information from the RFID tag 10 at various positions ( Can be obtained).
Further, the plurality of RFID tags 10 are provided in the vicinity of the peripheral portion 14 where the opening 15 is formed. In a plurality of RFID tags 10, even if the radio waves are relatively weak, the information of the RFID tag 10 can easily reach the external RFID tag 10, and the harvested product itself can suppress the transmission of radio waves. it can.

The peripheral portion 14 includes a vertical wall 14a that stands up from the bottom 13 and a horizontal wall 14b that stands up from the bottom 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 on the RFID tag 10 can be transmitted to the outside from at least both the vertical wall 14a side and the horizontal wall 14b side, and the RFID reader 20 can easily acquire the information on the RFID tag 10.

The RFID tag 10 is a passive tag having a storage unit 101 that stores identification information that identifies the storage unit 12 (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 a passive tag, the range of radio waves transmitted (output) from the plurality of RFID tags 10 can be adjusted to the size of the containment device 11, or the RFID tag 10 can be placed at a predetermined position. It is possible to set the range in which radio waves can be received.

In addition, the harvest management system includes a plurality of first RFID tags 10A for transmitting information regarding the first container 11A, a plurality of second RFID tags 10B for transmitting information regarding the second container 11B, and a grain first container 11A. To the information received by the RFID reader 20 and the RFID reader 20 which are provided in the combine 40 to be discharged to any of the second container 11B and can receive the information of the plurality of first RFID tags 10A and the information of the plurality of second RFID tags 10B. A computing device 30 for estimating the discharge destination of the grain discharged from the combine 40 based on the combination 40 is provided.

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

The mobile terminal 30 is a grain discharge destination based on the number of a plurality of first RFID tags 10A (first reception number) and the number of a plurality of second RFID tags 10B (second reception number) for which the RFID reader 20 has received information. To estimate. Since the number of receptions that can be received by the RFID reader 20 changes depending on the distance between the combine 40 and the container 11, it is possible to determine the grain discharge destination simply by comparing the first reception number and the second reception number. it can. For example, of 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 mobile terminal 30 has a plurality of first RFID tags 10A (number of receptions) and a plurality of second RFID tags 10B (receptions) for which the RFID reader 20 has received information, and a plurality of first RFID tags for the first container 11A. The grain discharge destination is estimated based on the mounting information of 10A and the mounting information of the plurality of second RFID tags 10B with respect to the second container 11B. For example, when the number of the first RFID tags 10A attached to the first container 11A and the number of the second RFID tags 10B attached to the second container 11B are different, not only the number of received items but also the attachment information is provided as supplementary information. By using it, it can be determined as a grain discharge destination.

By the way, the RFID reader 20 includes a change 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 reading intensity of the radio wave from the RFID tag 10. The change unit 20a of the RFID reader 20 changes the reception sensitivity when calibrating with the RFID tag 10.
The mobile terminal 30 has a setting unit 35 for performing calibration. The setting unit 35 is composed of a program or the like stored in the mobile terminal 30. When the program of the mobile terminal 30 is started, the setting unit 35 displays on the display unit 33 of the mobile terminal 30 indicating that the calibration mode is set. In addition, 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 tip end portion (discharge port 49b1) of the lateral feed portion 49b is arranged above the central portion of the predetermined container 11. Then, when the start button displayed on the display unit 33 of the mobile terminal 30 is selected with the tip portion (discharge port 49b1) of the lateral feed unit 49b stopped, the calibration is started. When the calibration is started, the RFID reader 20 outputs radio waves and measures the radio wave intensity of the RFID tag 10. Further, the change unit 20a of the RFID reader 20 gradually reduces the reception sensitivity from the maximum value in response to the start of calibration. When the radio field intensity of all the RFID tags 10 attached to the predetermined container 11 is equal to or higher than the predetermined value (at least when the identification information can be received), for example, the setting unit 35 of the mobile terminal 30 has a predetermined reception sensitivity. , "Identified" is displayed on the display unit 33. On the other hand, when the setting unit 35 of the mobile terminal 30 has a predetermined reception sensitivity and 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, "Could not be identified" is displayed on the display unit 33. Then, 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 or not the radio wave intensity of the RFID tag 10 is equal to or higher than a predetermined value while changing the reception sensitivity. However, when the ejection work is actually performed, it is determined. The receiving sensitivity may be changed to estimate the grain discharge destination.
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 explain by taking as an example the estimation of the grain discharge destination based on the radio wave intensity, but the estimation of the discharge destination is not limited to the radio wave intensity, and all the above-mentioned methods are adopted. Can be done.

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. The estimation unit 32 displays, for example, 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 the estimation start button 36 on the estimation display screen Q1. The estimation unit 32 displays the scale unit 37 from the upper limit to the lower limit of the reception sensitivity of the RFID reader 20 and the designation unit 38 for designating the reception sensitivity on the estimation display screen Q1. The designated unit 38 can be moved along the scale unit 37, and the reception sensitivity can be changed by moving the designated 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 estimation display screen Q1, the radio field intensities of the first RFID tag 10A and the second RFID tag 10B obtained by the estimation unit 32 are displayed. In addition, the total radio field strength of all tags A to D corresponding to the first container 11A (first total) and the total radio field strength of all tags E to G corresponding to the second container 11B (first total). 2 total), the difference in radio field intensity between the first total and the second total is displayed. In addition, the container 11 estimated by the estimation unit 32 of the mobile terminal 30 is displayed. Here, if the difference in radio wave intensity is less than a predetermined value (determination threshold value) 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 broadcast information is displayed on the estimated display screen Q1 of the mobile terminal 30.

According to the 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 housing 11, the arrangement of the housings 11, the mounting interval of the first RFID tag 10A with respect to the housing 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 sensitivity of both is changed by lowering the reception sensitivity. For example, the difference in radio field intensity can be increased.

When the discharge destination of the grain cannot be estimated, the mobile terminal 30 outputs notification information indicating that the discharge destination cannot be estimated. The operator or the like can grasp that the discharge destination cannot be estimated regardless of whether the calibration or the discharge work is in progress. It is possible to take measures when the discharge destination cannot be estimated. For example, the grain discharge position (the position of the discharge port 49b1 with respect to the container 11) can be changed from the current position to another position, and the estimation of the discharge destination can be attempted again. It is possible to carry out the discharge work while making it possible to estimate.

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

The emission destination of the grain is estimated based on the radio wave intensity of the second device 80B received by the device 81. 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 with the second device 80B provided in the second container 11B. The one with the stronger radio field intensity of the first device 80A or the second device 80B can be determined as the grain discharge destination.

The mobile terminal 82 estimates the grain discharge destination based on the presence or 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 changes depending on the distance between the combine 40 and the accommodating device 11, the number of first receptions of the plurality of first devices 80A and the number of second receptions of the plurality of second devices 80B By comparing the above, it can be easily determined as the grain discharge destination.

It can be determined as a grain discharge destination.

The receiving device 81 can adjust the reception sensitivity of the radio waves of the first device 80A and the second device 80B. The operator or the like can grasp that the discharge destination cannot be estimated regardless of whether the calibration or the discharge work is in progress. It is possible to take measures when the discharge destination cannot be estimated.
