The quantity information acquisition unit 84 acquires quantity information L based on the output of the mass measurement module 73. Specifically, the quantity information acquisition unit 84 determines whether the container B is filled with the crop A based on the output of the mass measurement module 73 at the time when the container B is full of the crop A or when the storage of the crop A in the container B is finished. The mass of the stored crop A is calculated, and the calculated value and time are stored in the storage unit 89 as amount information L. The mass of the crop A stored in the container B is calculated by subtracting the mass of the container B (the mass of the empty state, which has been measured or set in advance; the tare weight) from the output value of the mass measurement module 73. This is done by

The quality information acquisition unit 85 acquires quality information M based on the output of the quality measurement module 74. Specifically, the quality information acquisition unit 85 analyzes the captured image of the crop A generated by the quality measurement module 74, acquires data indicating the quality of the crop A, and stores the acquired data and time as quality information M. 89. The data indicating the quality of crop A is, for example, the size, shape, color, etc. of crop A.

The information may be transmitted via a wireless or wired communication network, or via an information medium.

The management server 200 includes a control section 181 and a storage section 189. The control unit 181 includes a container information generation unit 182 and a storage location information generation unit 183.

The control unit 181 causes the storage unit 189 to store the position information J, identification information K, quantity information L, and quality information M received from the harvester 100.

The container information generation section 182 generates container information N based on the position information J, identification information K, quantity information L, and quality information M stored in the storage section 189, and causes the storage section 189 to store the container information N.

The container information N is generated, for example, as follows. The container information generation unit 182 refers to the identification information K and specifies the time period (starting period and ending period) in which a certain container B was set in the harvesting machine 100. The container information generation unit 182 specifies the position information J corresponding to the specified time period, and specifies the aircraft position indicated by the specified position information J as the position where the crop A stored in the container B was harvested. .

Further, the container information generation unit 182 specifies the amount information L corresponding to the end of the specified time period, and converts the amount of crop A indicated by the specified amount information L into the amount of crop A contained in the container B. Specify as.

Furthermore, the container information generation unit 182 specifies quality information M corresponding to the specified time period, and specifies the quality of the crop A indicated by the specified quality information M as the quality of the crop A stored in the container B. do. The container information generation unit 182 generates container information N from the specified position information J, identification information K, quantity information L, and quality information M.

Here, the flow of generating container information N based on the quality information M specified as described above will be described in detail. The container information generation unit 182 generates in-container quality information Q based on the quality information M specified as described above. More specifically, by combining the quality information M identified as described above as one in-container quality information Q (for example, by assigning the same tag to each identified quality information M), the in-container quality information Generate Q. Container information N is then generated by associating the identified position information J, quantity information L, and container quality information Q with the identification information K. In this embodiment, as shown in FIG. 1, the container information N includes the identified identification information K, quantity information L, locus information T, and in-container quality information Q.

Here, the trajectory information T is information indicating the trajectory of the harvester 100 corresponding to the time period specified as described above. The trajectory information T is generated by the container information generation unit 182 based on the position information J specified as described above.

In this way, the information management system generates container information that shows container B in association with in-container quality information Q that indicates the quality of crop A stored in container B, based on quality information M and identification information K. It includes a container information generation section 182 that generates N.

FIG. 7 shows an example of the correspondence between the in-container quality information Q indicated by the container information N and the container B. In FIG. As shown in FIG. 7, in this example, the quality of crop A is expressed in three levels: "excellent," "good," and "fair." The quality information M is information indicating this classification. Further, in this example, the quality of crop A is determined in three stages based on the size, shape, color, etc. of crop A obtained by image analysis of the captured image of crop A generated by the quality measurement module 74. . Image analysis can also be performed using a trained model generated by machine learning, or can be performed by any means using artificial intelligence.

Note that the present invention is not limited to this. For example, the quality of crop A may be represented by fewer than three classifications, or may be represented by more than three classifications. Further, the quality of the crop A may be expressed not by classification but by numerical values such as moisture value and sugar content, and the quality information M may be information indicating the numerical values.

In the example shown in FIG. 7, the first information Q1 and the container B whose identification number is 1 are shown in correspondence. Further, the second information Q2 and the container B whose identification number is 2 are shown in correspondence. Note that both the first information Q1 and the second information Q2 are in-container quality information Q.

Moreover, in the example shown in FIG. 7, the in-container quality information Q is information indicating the quality of each of the plurality of crops A housed in the container B in the order in which they were harvested.

Note that the present invention is not limited to this. For example, the in-container quality information Q indicates the ratio of the number of crops A that corresponds to each category to the number of crops A stored in container B (for example, the ratio of "excellent", "good", and "fair"). It may be information, or it may be information indicating which category has the largest number of applicable crops A among each category, or information such as the average quality or standard deviation of the crop A stored in container B. It may be a statistical value or a frequency distribution (for example, the number of S, M, and L sizes).

Further, as shown in FIG. 1, the storage location information generation unit 183 uses the location information J and identification information K stored in the storage unit 189 and the time period specified by the container information generation unit 182 as described above. Based on this, container storage location information P is generated and stored in the storage unit 189.

The container storage information P is generated, for example, as follows. The storage location information generation unit 183 specifies the time when the container B was removed from the harvester 100 based on the time period specified as described above. The storage location information generation unit 183 generates container storage information P based on the location information J corresponding to the specified time and the identification information K. More specifically, the storage location information generation unit 183 generates container storage information P by associating the identification information K with the position information J corresponding to the specified time. Note that the position information J corresponding to the specified time is position information J indicating the position of the harvester 100 at the specified time.

In this way, the information management system determines the location of the container B removed from the harvester 100 based on the location information J and the identification information K corresponding to the time when the container B was removed from the harvester 100. It includes a storage location information generation unit 183 that generates container storage information P indicating the location of the container B in a state where it is identified.

Further, as shown in FIG. 6, the information management system includes a display section 21. The display unit 21 in this embodiment is a mobile communication terminal having a display. However, the present invention is not limited thereto, and the display unit 21 may be, for example, a display mounted on the harvester 100 or a display of a personal computer of an administrator.

The control unit 181 transmits the container storage information P and container information N stored in the storage unit 189 to the display unit 21. These information may be sent each time the information is generated, when the harvesting work for one container B is completed, or all at once at the end of the day's work. good. The information may be transmitted via a wireless or wired communication network, or via an information medium.

The display unit 21 displays a container map 300 as shown in FIG. 2 based on the container storage information P received from the control unit 181.

In this way, the information management system uses the display unit 21 to display the container map 300 showing the location of the container B removed from the harvester 100 with the container B identified, based on the container storage location information P. Equipped with

Further, the display unit 21 can display the in-container quality information Q corresponding to the container B in the container map 300, as shown in FIG. 2, based on the container information N received from the control unit 181.

More specifically, in the example shown in FIG. 2, in-container quality information Q is displayed in container information icons D1, D2, and D3. In this example, the in-container quality information Q indicates the average quality of the crop A stored in the container B.

In this way, the display unit 21 can display the in-container quality information Q corresponding to the container B in the container map 300 based on the container information N.

Note that, based on the container information N, the display unit 21 can display other information included in the container information N, such as quantity information L, in addition to the in-container quality information Q corresponding to the container B in the container map 300. It may be configured as follows.

Note that the present invention is not limited to this, and the predetermined standard may be any standard as long as it can be determined based on the quality information M whether or not it is satisfied.

Furthermore, in this first alternative embodiment, among the crops A, the crop A that does not meet the predetermined criteria is a substandard crop 2A.

Then, when the specific crop 1A is conveyed by the conveyor 14, the determining unit 75 changes the attitude of the sorting unit 17 so that it is swung forward before the specific crop 1A reaches the conveyor 14. . Thereby, the specific crop 1A is guided to the rear side of the partition wall 14a by the sorting section 17. Then, the specific crop 1A is conveyed to the right by the conveyor 14 and stored in the first container B1.

Further, when the non-standard crop 2A is conveyed by the conveyor 14, the determining unit 75 causes the sorting unit 17 to take a posture in which it is swung rearward before the non-standard crop 2A reaches the conveyor 14. Change posture. Thereby, the non-standard crops 2A are guided by the sorting section 17 to the front side of the partition wall 14a. Then, the non-standard crop 2A is transported to the right by the conveyor 14 and stored in the second container B2.

That is, under the control of the determining unit 75, the sorting unit 17 sorts the crops A so that the specific crop 1A is accommodated in the first container B1, and crops A other than the specific crop 1A are not accommodated in the first container B1. .

In this way, the information management system determines that the specific crop 1A is stored in the first container B1, which is one of the plurality of containers B, and that the specific crop 1A is stored in the first container B1, based on the determination result by the determination unit 75. A sorting section 17 is provided to sort crops A so that crops A other than crop 1A are not accommodated.

[Other embodiments]
(1) The location information acquisition unit 82, the identification information acquisition unit 83, the quantity information acquisition unit 84, and the quality information acquisition unit 85 may be provided outside the harvester 100 (for example, the management server 200, a mobile information terminal, etc.). good. The container information generation unit 182 and the storage location information generation unit 183 may be provided outside the management server 200 (for example, the control device 80 of the harvester 100, a mobile information terminal, etc.). All components of the information management system may be provided in the harvester 100.

(2) The identification information K may be acquired in the following manner. At the start of harvesting work, in response to the operator turning on the work clutch, the identification information acquisition section 83 activates the identification module 72 to read information. Thereafter, the identification information acquisition unit 83 operates the identification module 72 to read information at predetermined time intervals (for example, every 10 seconds) while performing the harvesting work. The identification information acquisition unit 83 causes the storage unit 89 to store the read information, the position coordinates of the harvester 100 at that time, and the time as identification information K.

Note that when reading information by the identification module 72, information on a container B that is not set in the harvester 100 (for example, another container B installed in the harvester 100) may be read, or errors due to noise etc. reading of information may occur. As a countermeasure against such false detection, the identification information K may be modified as described below. One cycle is defined as the period from ON to OFF of the work clutch, and the most frequently read information during one cycle is the information that identifies container B in that cycle (the most frequent information). Information that differs from the most frequent information is treated as an error. It is regarded as a detection and is rewritten to the most frequent information. Note that the beginning of one cycle may be a mounting operation for container B (for example, a leftward movement of a crane that suspends container B). The final stage of one cycle may be an operation for attaching and detaching the container B (for example, movement of the crane that suspends the container B to the right).

(3) The identification module 72 may be a barcode reader or the like.

(4) The amount information L may be the number or volume of crops A. The amount information acquisition unit 84 may acquire the amount information L using other methods. For example, the quantity information acquisition unit 84 may acquire the number of crops A accommodated in the container B as the quantity information L based on the output of a phototube sensor that detects the crops A transported on the pulling belt 6. The quantity information acquisition unit 84 may acquire the number of crops A accommodated in the container B as the quantity information L based on the number of images output by the quality measurement module 74. The quantity information acquisition unit 84 may calculate the volume of the crop A by analyzing the image output by the quality measurement module 74, and acquire the volume of the crop A accommodated in the container B as the quantity information L. The quantity information acquisition unit 84 may calculate the mass of the crop A by analyzing the image output by the quality measurement module 74, and acquire the mass of the crop A accommodated in the container B as the quantity information L.

(5) The quality information M may be the size, length, diameter, presence or absence of defects, sugar content, moisture content, etc. of the crop A. The quality measurement module 74 may be a three-dimensional scanner, a sugar content measurement device, a water content measurement device, or the like.

(6) In the embodiment described above, the quality measurement module 74 images the crop A, and the quality information acquisition unit 85 acquires the quality information M by analyzing the captured image of the crop A. However, the present invention is not limited thereto. Instead of this configuration, the quality information acquisition unit 85 may be configured to directly measure the quality of the crop A. For example, the quality information acquisition unit 85 may be a camera that images the crop A harvested by the harvester 100. Furthermore, the quality information acquisition unit 85 may be a sugar content meter that measures the sugar content of the crop A harvested by the harvester 100.

When the quality information acquisition unit 85 is a sugar content meter, the quality information acquisition unit 85 may be configured to measure the sugar content using the juice collected from the crop A. In this case, for example, the juice coming out from the part of the crop A that has been cut by the rotary blade 7 may be used.

Furthermore, when the quality information acquisition unit 85 is a sugar content meter, the quality information acquisition unit 85 may be configured to irradiate the crop A with near-infrared light to measure the sugar content.

(7) Container information N may include positional coordinates within the field as information indicating the harvested position of crop A stored in container B, or may include the position of a ridge within the field or the location of a ridge within the field. Information that can be specified (for example, the number of the ridge) may be included, or the position (location) of the field or information that can be specified (for example, the name and number of the field) may be included.

(8) In the container map 300, the position where the crop A is harvested may be shown in a form other than the travel trajectory of the harvester 100. For example, the position where crop A was harvested may be indicated by a point, area, or the like. Further, the traveling trajectory of the harvester 100 may include a traveling trajectory during non-harvesting (for example, turning).

(9) The container B may have other forms, such as a box or a container. The full container B may not be lowered from the harvester 100 to the field, but may remain mounted on the harvester 100.

(10) Crop A may be vegetables other than carrots (onions, radish, etc.), or may be grains. The harvester 100 may be, for example, an onion harvester, a radish harvester, a combine harvester, or the like.

(11) The structure may be such that the operator of the chair 16 can take out the defective crop A while the crop A is being conveyed to the right by the conveyor 14. In addition, a camera that images the defective crops A being taken out, or a camera that images the crops A just before being stored in the container B is installed at a position downstream of the chair 16 in the conveyance direction by the conveyor 14. It's okay to be left behind. By comparing the image taken by this camera with the image taken by the quality measurement module 74, it is possible to identify the crop A that was removed by the operator on the chair 16. This identification may be performed by the quality information acquisition unit 85, for example. Furthermore, in the quality information acquisition unit 85, the quality of crop A is determined using artificial intelligence, and the captured image of crop A identified in this way is configured to be used for learning of this artificial intelligence. You can leave it there. In addition, the container information generation unit 182 generates in-container quality information Q based only on the quality information M regarding the crop A that was not removed by the operator of the chair 16 and was accommodated in the container B, out of the quality information M. At the same time, container information N may be generated.

(12) In the above embodiment, the quality information acquisition unit 85 acquires the quality information M by analyzing the captured image of the crop A generated by the quality measurement module 74. However, the present invention is not limited thereto. For example, the quality information acquisition unit 85 may be configured to acquire quality information M generated outside the information management system.

Note that the configurations disclosed in the above-described embodiments (including other embodiments, the same applies hereinafter) can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction occurs. Further, the embodiments disclosed in this specification are illustrative, and the embodiments of the present invention are not limited thereto, and can be modified as appropriate without departing from the purpose of the present invention.
