[0005] The technology described in Patent Document 1 can manage information about harvested products, but it cannot properly grasp the progress of collection of containers that actually contain the harvested products. The quality of harvested products, such as sugarcane, deteriorates over time after harvesting. For this reason, it is important to grasp the progress of collection.

[0006] In view of the above circumstances, one of the objects of the present disclosure is to support progress management by a user by appropriately notifying the progress of harvest collection.

[0013] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the work management system 1000 includes a work management apparatus 100 and a terminal 200. The work management apparatus 100 is communicably connected to one or more terminals 200 and a work apparatus 30 via a network 20, for example, the Internet.

[0014] The work equipment 30 harvests crops, such as sugarcane, grown in a field and discharges the harvested crops back into the field. Examples of the work equipment 30 include a tractor that pulls a harvesting device that harvests the crops, a harvester formed integrally with the harvesting device, and the like. As shown in FIG. 2, the work equipment 30 includes, for example, a lifting device 310, a reaping device 320, a transporting device 330, a winnowing device 340, and a discharging device 350. The lifting device 310 lifts up fallen sugarcane in the field. The lifted sugarcane is then harvested by the reaping device 320. The transporting device 330 cuts the harvested sugarcane into pieces of predetermined size and transports them to the winnowing device 340. The winnowing device 340 separates the sugarcane stalks to be harvested from the sugarcane leaves and dust, transports the sugarcane stalks to the discharge device 350, and discharges the sugarcane leaves and dust to the side or rear. The discharge device 350 stores the sugarcane stalks in a storage container, for example, a bag, and discharges the storage container into the field when the sugarcane stalks exceed a predetermined amount.

[0015] Furthermore, while working in the field, the work device 30 transmits operation information indicating its operating state at each time to the work management apparatus 100. For example, the operation information includes position information of the work device 30. The work device 30 is equipped with a positioning device, such as a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position of the work device 30 at each time it moves. The operation information may include, for example, information indicating the state of each machine of the work device 30, such as the ON / OFF status of various clutches, and the state of the mechanisms that operate when the discharge device 350 discharges the storage container. Furthermore, when the work device 30 is a vehicle that tows the work machine, such as a tractor, the operation information may include information such as the PTO (power take-off) rotation speed when transmitting power to the work machine, and information indicating the attitude of the work machine, such as the hitch height and lift arm angle.

[0016] 1 determines the location of a group of harvested products, such as a storage container, and the time at which the group of harvested products was discharged, based on operation information acquired from the operation device 30. Information indicating the determined location of the group of harvested products and the time at which the group of harvested products was discharged is output from the operation management device 100 to the terminal 200.

[0017] Information indicating the location of the harvested products and the time of discharge is displayed, for example, on the first terminal 200-1 and notified to a user, for example, a worker who collects the harvested products discharged in the field. For example, as shown in FIG. 3 , the terminal 200 displays the fields 500 in which the harvested products exist, such as the first field 500-1, the second field 500-2, the third field 500-3, and the fourth field 500-4, in a manner that enables them to be distinguished from the other fields 500. For example, the terminal 200 displays, for each field 500, remaining information 510 indicating the quantity of the harvested products discharged from the work device 30 and the quantity of the harvested products that have not yet been collected. The terminal 200 may also display an image in which the display format of the remaining information 510, for example, the color or pattern, is changed depending on the time elapsed since the discharge. Based on the image displayed on the terminal 200, the user can determine the priority of collecting the harvested crops.

[0018] Furthermore, information indicating the location of the harvested crops and the time of discharge may be displayed on the second terminal 200-2 and reported to a user, for example, a manager who monitors the progress of the harvest collection work at the post-harvest facility. The manager can check the progress of the harvested crop collection work based on the image displayed on the terminal 200. This allows the manager to instruct the worker who collects the harvested crops which crops to collect.

[0019] Information representing the collected harvested products is registered in the terminal 200 by a user, for example, a worker who collects the harvested products. The work management apparatus 100 then determines which of the discarded harvested products remain in the field 500 and outputs information representing the quantity of the remaining products and the time of their disposal to the terminal 200. This allows the user to check the progress of the collection work in real time. This allows the user to perform the collection work efficiently and reduce the time elapsed from the time of disposal to collection.

[0020] Here, the operation information output by the working device 30 may include information representing the state of a mechanism that operates when the discharge device 350 discharges the harvested crops. For example, as shown in FIGS. 4A and 4B , the discharge device 350 includes a hydraulic cylinder 351, a container locking unit 352, and a storage container 353. For example, as shown in FIG. 4B , when the discharge device 350 discharges the harvested crops, specifically the storage container 353, the hydraulic cylinder 351 is extended. Therefore, the operation information may include information representing the pressure of the hydraulic cylinder 351 at each time. The operation information may also include information representing the length of the hydraulic cylinder 351 at each time.

[0021] Furthermore, the container locking portion 352 tilts when the discharging device 350 discharges the storage container 353. For this reason, the operation information may include information representing the tilt angle of the container locking portion 352 at each time. Furthermore, each connection portion of the discharging device 350, for example, a connection portion at the end of a hydraulic cylinder, rotates relative to the connected counterpart when the discharging device 350 discharges the storage container 353. For this reason, the operation information may include information representing the relative angle of each connection portion of the discharging device 350. Furthermore, the operation information may include information representing the state of an operating portion, for example, an operating lever, that is operated when the discharging device 350 discharges the storage container 353.

[0022] Furthermore, when the discharge device 350 discharges the harvested crop, the height of the harvested crop stored in the storage container 353 decreases. Therefore, the operation information may include information indicating the height of the harvested crop stored in the storage container 353.

[0023] (Work management system configuration) The configuration of the work management device 100 included in the work management system 1000 shown in FIG. 1 will be described. As shown in FIG. 5, the work management device 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information used by the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 also outputs the results of processing executed by the calculation device 120. The input / output device 110 includes various input and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input / output device 110 may be omitted.

[0024] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 130 transfers operation information acquired from the maintenance device 30 to the calculation device 120. The communication device 130 also transfers signals generated by the calculation device 120 to the terminal 200. The communication device 130 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0025] The storage device 140 stores various data for determining the progress of the collection operation of the harvested crops discharged in the field 500, such as operation data 410, field data 420, and an operation management program 430. The storage device 140 is used as a non-transitory tangible storage medium for storing the operation management program 430. The operation management program 430 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

[0026] The work data 410 stores information about the harvested products discharged from the work device 30. For example, the work data 410 stores information about the work performed for each harvested product group from the time the harvested product group is discharged from the work device 30 until the harvested product group is transported to the post-harvest facility. For example, as shown in FIG. 6, the work data 410 stores information that associates the work device 30 that discharged the harvested product group, the discharge time indicating the time the harvested product group was discharged, a harvested product group number for identifying the harvested product group, and the discharge location indicating the location where the harvested product group was discharged. The harvested product group number may represent an identifier assigned to a storage container that contains the harvested product. The work data 410 also stores information indicating the collection device 40 that collected the harvested product group and the time of collection. The work data 410 stores the delivery time indicating the time the collection device 40 delivered the harvested product group to the post-harvest facility. Furthermore, the work data 410 may store a status indicating the status of each harvested product group. The information stored in the work data 410 is stored in association with a work number that indicates work related to one harvest group.

[0027] FIG. 6 shows, for example, the work data 410 as of 10:00 AM on January 11, 2022. In the example shown in FIG. 6, the work with a "work number" of "1" represents the work from when a group of harvested products is discharged until it is transported to the post-harvest facility. FIG. 6 shows that, for the work with a "work number" of "1," a "first work device" performed the harvesting work and the group of harvested products was discharged at 11:30 AM on January 8, 2022. FIG. 6 also shows that, for the work with a "work number" of "1," the identifier of the discharged group of harvested products, for example, the identifier assigned to the storage container 353, is "1," and the group of harvested products was discharged to coordinates "X1, Y1." FIG. 6 also shows that, for the work with a "work number" of "1," the group of harvested products has not been collected by the collection device 40. The "status" of the work with a "work number" of "1" is set to "warning," indicating that the time elapsed since the discharge time has exceeded a predetermined period.

[0028] FIG. 6 also shows that in the operation with the "operation number" "2," the "second operation device" performed the harvesting work and the harvested product group was discharged at "2022 / 1 / 10 10:30." The identifier of the harvested product group in the operation with the "operation number" "2" is "2," and the harvested product group was discharged at coordinates "X2, Y2." FIG. 6 also shows that the harvested product group was collected by the "first collection device" at "2022 / 1 / 10 12:00" and delivered to the post-harvest facility at "2022 / 1 / 10 12:30." Therefore, the "status" of the operation with the "operation number" "2" is set to "delivered," indicating that the harvested product group has been delivered to the post-harvest facility.

[0029] In this way, the work data 410 stores information about each group of harvested products discharged from the work device 30.

[0030] The field data 420 shown in FIG. 5 stores information about the field 500 on which the work device 30 performs work. For example, the field data 420 stores the position, area, harvested product group number, and remaining product group number of the field 500, as shown in FIG. 7. The "field position" representing the position of the field 500 represents, for example, the geometric center of the field 500. The "field area" representing the area of ​​the field 500 represents, for example, the area included in the field 500. The "harvested product group number" represents the harvested product group number of the harvested product group discharged in the field 500, and the "remaining product group number" represents the harvested product group number of the remaining product group remaining in the field 500. The field data 420 may also store the "work number" of FIG. 6, which represents the work performed in the field 500.

[0031] 5 executes a work management program 430 to perform various data processing operations to determine the progress of the work of collecting the harvested crops discharged in the farm field 500. For example, the calculation device 120 includes a central processing unit (CPU) and the like.

[0032] By reading and executing the work management program 430, the calculation device 120 realizes a discharge determination unit 150, a residual extraction unit 160, an elapsed time determination unit 170, and an output unit 180, as shown in FIG. 8. The discharge determination unit 150 determines the discharge location and discharge time of the harvested product groups based on the operation information of the work device 30. The residual extraction unit 160 extracts residual groups representing the harvested product groups remaining in the field 500 from the harvested product groups discharged to the field 500. The elapsed time determination unit 170 determines the time elapsed since the discharge time for the residual groups. The output unit 180 outputs progress information representing the progress of the collection work based on the quantity of the residual groups.

[0033] Next, the configuration of the terminal 200 will be described. As shown in Fig. 9, the terminal 200 includes an input / output device 210, an arithmetic device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information used by the arithmetic device 220 to execute processing is input to the input / output device 210. The input / output device 210 also outputs the results of processing executed by the arithmetic device 220. The input / output device 210 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel.

[0034] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 230 transfers information acquired from the work management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0035] The storage device 240 stores various data, such as a display program 440, for displaying information obtained from the work management device 100. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 440. The display program 440 may be provided as a computer program product recorded on a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

[0036] The arithmetic device 220 executes the display program 440 and performs various data processing for displaying information acquired from the work management device 100. For example, the arithmetic device 220 includes a central processing unit (CPU) and the like.

[0037] The arithmetic device 220 reads and executes the display program 440, thereby working in cooperation with the input / output device 210 to realize the display unit 250 as shown in Fig. 8. The display unit 250 displays the progress information acquired from the work management apparatus 100. In addition, the display unit 250 outputs collection information indicating the harvested product groups collected by the collection device 40 to the work management apparatus 100 in response to an input operation by the user.

[0038] (Operation of work management device) First, we will explain the operation of the work management system 1000 when the work device 30 discharges the harvested crops into the field 500. When the work device 30 is working in the field 500, it outputs operation information to the work management device 100. When the operation information is received from the work device 30, the calculation device 120 of the work management device 100 reads and executes the work management program 430. By executing the work management program 430, the calculation device 120 executes the processing shown in FIG. 10, which is part of the work management method.

[0039] In step S110, the discharge determination unit 150 implemented by the calculation device 120 determines the discharge position and discharge time when the harvested product group is discharged by the work device 30, based on the operation information of the work device 30. For example, the discharge determination unit 150 determines the discharge position and discharge time based on the operation information that represents the state of the mechanism of the discharge device 350 when the harvested product group is discharged. For example, when the operation information represents that the hydraulic cylinder 351 shown in FIG. 4B is extended, the discharge determination unit 150 determines the position represented by the operation information as the measured position, and determines the time corresponding to the operation information, for example, the time when the operation information was measured, as the discharge time.

[0040] The discharge determination unit 150 may also determine the discharge position and discharge time based on operation information representing the mechanical state of the discharge device 350 when discharging the harvested products and operation information representing the mechanical state of the reaping device 320 when harvesting the harvested products. For example, the discharge determination unit 150 determines a candidate discharge time based on operation information representing the mechanical state of the discharge device 350 when discharging the harvested products. When operation information representing that the harvested products are being harvested is included between two determined candidate discharge times, the discharge determination unit 150 determines the later of the two candidate discharge times as the discharge time when the harvested products are being discharged. The discharge determination unit 150 determines the position corresponding to the determined discharge time as the discharge position. Note that the discharge determination unit 150 may also determine that the working device 30 is harvesting the harvested products when the operation information represents the state of a mechanism included in any device of the working device 30 when harvesting the harvested products. The discharge determination unit 150 can more accurately determine the discharge time by using the operation information when the harvested products are being harvested. The discharge determination unit 150 associates the name of the work device 30 that output the operation information with the determined discharge time and discharge position and stores them in the work data 410. The discharge determination unit 150 also determines a unique harvest group number and stores the determined harvest group number in the work data 410. When the operation information includes an identifier that identifies the harvest group, the discharge determination unit 150 stores the identifier of the harvest group in the work data 410 as the harvest group number.

[0041] Furthermore, the discharge determination unit 150 stores the harvest group number in the field data 420 shown in FIG. 7 in association with the field 500 where the implement 30 performed the work. The field 500 where the implement 30 performed the work is determined by the discharge determination unit 150. For example, the discharge determination unit 150 extracts the field 500 whose area includes the position of the implement 30 based on the field data 420, and determines the extracted field 500 as the field 500 where the work was performed by the implement 30. For example, the discharge determination unit 150 determines the field 500 that includes the discharge position where the implement 30 performed the harvest group as the field 500 where the implement 30 performed the work. The discharge determination unit 150 may also determine the field 500 that the implement 30 entered just before the discharge time at which the harvested crop was discharged as the field 500 where the implement 30 performed work. The discharge determination unit 150 may also determine the field 500 that includes the position of the implement 30 when the harvested crop is being harvested as the field 500 where the implement 30 performed work.

[0042] In step S120 shown in FIG. 10 , the residue extraction unit 160 extracts the harvested products remaining in the field 500 based on the work data 410. For example, the residue extraction unit 160 extracts the harvested products that have not been collected by the collection device 40 in the work data 410 as the remaining harvested products remaining in the field 500. For example, the residue extraction unit 160 extracts the work for which the collection time is not recorded, such as the "work number," from the work data 410, and determines the harvested product group number corresponding to the extracted work as the harvested product group number of the remaining harvested products. The residue extraction unit 160 stores the determined harvested product group number of the remaining harvested products in the work data 410 in association with the field 500 in which the remaining harvested products remain. The field 500 in which the remaining harvested products remain is determined based on the discharge location where the remaining harvested products were discharged and the area of ​​the field 500. The residual extraction unit 160 determines the field 500 including the discharge position where the residual group was discharged as the field 500 where the residual group remains.

[0043] In the example shown in FIG. 6, the residue extraction unit 160 extracts the work with the "work number" of "1" and the work with the "work number" of "5" as work for which the "collection time" or "collection device" is not recorded. The residue extraction unit 160 extracts the "harvest group number" of "1" corresponding to the work with the "work number" of "1" and the "harvest group number" of "5" corresponding to the work with the "work number" of "5." Furthermore, for the work with the "work number" of "1," the residue extraction unit 160 determines the field 500 with the "discharge location" of "X1, Y1," for example, the second field 500-2, as the field 500 where the residue remains. The residue extraction unit 160 stores the "harvest group number" of "1" for the work with the "work number" of "1" in the second field 500-2 of the field data 420 shown in FIG. 7. Similarly, the residue extraction unit 160 stores the harvest number "5" corresponding to the "residual group number" of the first field 500-1, which includes "X5, Y5," to which the residual group with the "harvest group number" "5" was discharged.

[0044] In step S130 shown in FIG. 10 , the elapsed time determination unit 170 determines the elapsed time elapsed since the discharge time for the remaining sorghum left in the field 500. For example, as shown in the work data 410 in FIG. 6 , the elapsed time determination unit 170 may determine the “status” of the work in which the remaining sorghum remains in the field 500 based on the determined elapsed time. For example, the elapsed time determination unit 170 stores “Warning” in the “status” for work in which the elapsed time is a predetermined time, for example, 48 hours or more. For work in which the elapsed time is less than the predetermined time, the elapsed time determination unit 170 stores “Harvested” in the “status.” The “status” for work in which the harvested product remains in the field 500 may represent three or more states depending on the elapsed time. For example, the elapsed time determination unit 170 compares the elapsed time with two or more predetermined times to determine the “status” of the work.

[0045] In step S140, the output unit 180 outputs progress information indicating the progress status regarding the collection of the harvested products to the terminal 200. For example, the output unit 180 determines the progress status based on the quantity of remaining sorghum remaining in the field 500. For example, as shown in FIG. 3, the output unit 180 determines the quantity of remaining sorghum in each field 500, such as "1" which is the quantity of remaining sorghum in the first field 500-1 and "1" which is the quantity of remaining sorghum in the second field 500-2, as the progress status. Furthermore, in addition to the quantity of remaining sorghum in each field 500, the output unit 180 may also determine the quantity of harvested products discharged in the field 500, such as "4" which is the quantity of harvested products in the first field 500-1 and "1" which is the quantity of harvested products in the second field 500-2, as the progress status.

[0046] In step S150 shown in FIG. 10 , the display unit 250 of the terminal 200 displays the progress information acquired from the work management apparatus 100 on the input / output device 210. For example, as shown in FIG. 3 , the display unit 250 displays an image showing on a map the quantity of harvested product groups that have been discharged and the quantity of remaining residual groups for each field 500. For example, for each field 500, residual information 510 that indicates the quantity of remaining residual groups remaining in the field 500 is displayed. The residual information 510 may be displayed in the form of a fraction. For example, the quantity of harvested product groups that have been discharged is displayed as the denominator, and the quantity of remaining residual groups is displayed as the numerator.

[0047] In the example shown in FIG. 3, the first residual information 510-1 corresponding to the first field 500-1 indicates that the quantity of the harvested product group is "4" and that the quantity of the remaining group is "1." The second residual information 510-2 corresponding to the second field 500-2 indicates that the quantity of the harvested product group is "1" and that the quantity of the remaining group is "1." The third residual information 510-3 indicates that the quantity of the harvested product group is "3" and that the quantity of the remaining group is "1." The fourth residual information 510-4 indicates that the quantity of the harvested product group is "6" and that the quantity of the remaining group is "2."

[0048] Furthermore, the display format of the residual information 510, such as color, pattern, and outline thickness, may vary depending on the amount of time elapsed since the discharge of the residual group. For example, residual information 510 corresponding to a field 500 containing residual group whose elapsed time is greater than or equal to a predetermined time may be displayed in red, and residual information 510 corresponding to a field 500 not containing residual group whose elapsed time is greater than or equal to the predetermined time may be displayed in blue. For example, second residual information 510-2 is displayed in red because the corresponding second field 500-2 contains residual group whose elapsed time is greater than or equal to the predetermined time. Furthermore, first residual information 510-1 is displayed in blue because the corresponding first field 500-1 does not contain residual group whose elapsed time is greater than or equal to the predetermined time. The display unit 250 may classify the fields 500 into three or more categories depending on the amount of time elapsed, and display the corresponding residual information 510 in three or more display formats depending on the classification of the field 500.

[0049] The display unit 250 may display the progress information in different formats depending on the scale of the displayed map. For example, as shown in FIG. 11 , when the scale is smaller than a threshold, the display unit 250 may display the progress information by region. For example, the display unit 250 displays an image on a map in which regions containing residual groups for which a predetermined time or more has elapsed since the discharge time are distinguishable from other regions. For example, the display unit 250 displays regions containing residual groups for which a predetermined time or more has elapsed in red. In the example shown in FIG. 11 , the region representing "Region C" is displayed in red, and the regions representing "Region A" and "Region B" are displayed in another color, such as white. The display unit 250 may classify the regions into three or more categories based on elapsed time and display an image in which the corresponding regions are displayed in three or more display formats depending on the region classification. Note that the region may represent an area divided by any method, such as an administrative division, or an area divided based on latitude and longitude.

[0050] Furthermore, as shown in FIG. 12, the display unit 250 may display the quantity of remaining groups classified by the time elapsed since they were released for each region. The display unit 250 may display the quantity of remaining groups for which the elapsed time from the release time is equal to or greater than a predetermined time in a manner that makes it distinguishable from the quantities of other remaining groups. For example, as shown in FIG. 12, the display unit 250 may display an area representing the quantity of remaining groups for which the elapsed time is equal to or greater than a predetermined time in a different display format from the areas representing the quantities of other remaining groups. For example, in "region C," the display unit 250 displays an area representing the quantity of remaining groups for which the elapsed time is equal to or greater than 48 hours in red, and displays an area representing the quantity of other remaining groups in white.

[0051] In this way, a user, for example, a manager, can check the progress of the harvested crop collection work based on the image displayed on the terminal 200. The manager can easily find remaining crops, particularly those that have been there for a predetermined time or more. This allows the manager to instruct that remaining crops that have been there for a predetermined time or more be collected first. Similarly, workers collecting the harvested crops can also collect remaining crops that have been there for a predetermined time or more first. This allows users to collect the harvested crops efficiently, reducing the amount of harvested crops that are left in the field 500 for long periods of time.

[0052] Next, the operation of the work management system 1000 when a worker collects a harvested crop will be described. The worker inputs information about the harvested crop to be loaded onto the collection device 40 into the input / output device 210 of the terminal 200. When the worker inputs an operation to input information about the harvested crop to be collected into the input / output device 210 of the terminal 200, the arithmetic unit 220 of the terminal 200 executes the process shown in Fig. 13, which is part of the work management method.

[0053] In step S112, the display unit 250, which is realized by the calculation device 220 of the terminal 200, displays progress information regarding the harvested product collection work on the input / output device 210. For example, the display unit 250 requests the progress information from the work management apparatus 100 and acquires the progress information from the work management apparatus 100. Upon acquiring the progress information, the display unit 250 displays the progress information. For example, the display unit 250 displays information about the remaining product groups remaining in the field 500 on the input / output device 210. For example, the display unit 250 displays an image on a map showing the positions of the remaining product groups remaining in the field 500. The worker inputs a selection operation to the input / output device 210 to select the remaining product groups to be collected from the remaining product groups displayed on the map. The display unit 250 outputs collection information indicating the selected remaining product groups to the work management apparatus 100. For example, the collection information indicates the position of the selected remaining product groups and the time of selection. The collection information may also indicate the harvested product group number of the selected remaining product groups and the time of selection. The collection information also includes an identifier of the collection device 40 operated by the worker.

[0054] In step S114, the residue extraction unit 160 of the work management apparatus 100 stores the collection information acquired from the terminal 200 in the work data 410. For example, as shown in FIG. 6 , the residue extraction unit 160 stores the time indicated in the collection information and the identifier of the collection apparatus 40 in the work data 410 in association with the harvest group number of the remaining group indicated in the collection information.

[0055] For example, suppose that a worker selects a remaining group with a "harvest group number" of "4" on "2022 / 1 / 10 13:00" using the input / output device 210 of the terminal 200. In this case, the collection information represents the time of selection, "2022 / 1 / 10 13:00," the "harvest group number" of the selected remaining group, "4," and the identifier of the collection device 40 operated by the worker. Therefore, for the task with a "task number" of "4" corresponding to the "harvest group number" of "4," the residue extraction unit 160 stores the selected time, "2022 / 1 / 10 13:00," as the collection time, and stores the "second collection device" corresponding to the worker as the "collection device."

[0056] Furthermore, based on the collection information, the remainder extraction unit 160 updates the "status" of the task data 410. For example, the remainder extraction unit 160 updates the "status" of the task corresponding to the collection information to "in transport."

[0057] 13, the residual extraction unit 160 extracts the harvested crops remaining in the field 500 based on the work data 410. The processing from step S120 onwards is the same as the processing from step S120 onwards shown in FIG. 10, and therefore a description thereof will be omitted.

[0058] Next, the operation of the work management system 1000 when a worker delivers a group of harvested products to a post-harvest facility will be described. When the worker inputs information indicating that the group of harvested products will be delivered to the post-harvest facility into the input / output device 210 of the terminal 200, the arithmetic device 220 of the terminal 200 executes part of the processing of the work management method. The display unit 250 realized by the arithmetic device 220 outputs delivery information indicating that the group of harvested products has been delivered to the post-harvest facility to the work management device 100. For example, the delivery information indicates the time the information was input and the identifier of the collection device 40 operated by the worker.

[0059] The remainder extraction unit 160 of the work management apparatus 100 updates the work data 410 shown in FIG. 6 based on the delivery information. For example, the remainder extraction unit 160 extracts, from the work data 410, a work that corresponds to the identifier of the collection device 40 indicated in the delivery information. For example, in the example shown in FIG. 6, when the identifier of the collection device 40 indicated in the delivery information indicates the "first collection device," the remainder extraction unit 160 extracts a work with a "work number" of "2" and a work with a "work number" of "3" that are performed by the "first collection device." For the extracted work, the remainder extraction unit 160 stores the time indicated in the delivery information, for example, the time the information is input, as the "delivery time" in the work data 410. The remainder extraction unit 160 also updates the "status" of the extracted work to "delivered."

[0060] As a result, the work data 410 represents the current collection status of the harvest group. Therefore, the work management system 1000 can notify the user of the collection status of the harvest group based on the information stored in the work data 410.

[0061] (Variation) The configuration described in the embodiment is merely an example, and the configuration can be changed as long as the functionality is not impaired. For example, in step S112 shown in FIG. 13, the collection device 40 may output collection information regarding the collected harvested product groups to the work management device 100. For example, the collection device 40 measures the position of the remaining group to be collected and outputs collection information indicating the measured position of the remaining group to the work management device 100. The residue extraction unit 160 of the work management device 100 determines the remaining group whose discharge position is closest to the position indicated in the collection information as the remaining group collected by the collection device 40. In addition, the collection information output by the collection device 40 includes information indicating the time the remaining group was collected and the identifier of the collection device 40.

[0062] Furthermore, when the collection device 40 delivers the harvested crops to the post-harvest facility, a device installed at the post-harvest facility may output delivery information indicating the identifier of the collection device 40 delivering the harvested crops to the work management device 100. For example, the device installed at the post-harvest facility may determine the identifier of the collection device 40 by reading the number of the collection device 40. The determined identifier of the collection device 40 is output to the work management device 100 as delivery information. Furthermore, the collection device 40 may output the delivery information to the work management device 100. For example, the collection device 40 may output the collection information when the collection device 40 enters the area of ​​the post-harvest facility.

[0063] The work management system 1000 may estimate the time when the harvested products will be discharged and display information indicating the estimated time on the input / output device 210 of the terminal 200. For example, the discharge determination unit 150 estimates the estimated discharge time when the harvested products will next be discharged based on operation information of the work device 30. For example, the discharge determination unit 150 estimates the estimated discharge time when the harvested products will next be discharged based on operation information indicating that harvesting is being performed and the discharge time. For example, the discharge determination unit 150 estimates the estimated discharge time when the harvested products will next be discharged based on operation information of harvesting work between two adjacent discharge times in past operation information. For example, the discharge determination unit 150 estimates the estimated discharge time based on information about the harvesting work performed by the work device 30 between the two adjacent discharge times, such as statistical values ​​such as the work time and harvest yield, for example, the average, median, minimum, and maximum values. For example, the discharge determination unit 150 determines the work time since the work device 30 last discharged the harvested crop, and determines the difference between the determined work time and the past work time between two adjacent discharge times as the work time until the work device 30 discharges the harvested crop. The determined estimated discharge time is output to the terminal 200 as progress information.

[0064] Furthermore, the discharge determination unit 150 may estimate the progress rate until the harvest group is discharged based on information about the harvesting work performed by the work device 30 between two adjacent discharge times. For example, the discharge determination unit 150 determines the work time since the work device 30 last discharged the harvest group, and determines the progress rate as the ratio of the determined work time to the past work time between the two adjacent discharge times. The determined progress rate is output to the terminal 200 as progress information. The terminal 200 displays the progress rate included in the progress information.

[0065] The work management system 1000 may support progress management of any work in which the work device 30 discharges a harvested crop into the field 500 and the collection device 40 collects the discharged harvested crop. For example, the harvested crop may be a grass roll or a straw roll. The work management system 1000 may also manage not only the discharge of the harvested crop, but also the cutting down of the harvested crop and the turning over of the harvested crop. In this case, the work data 410 shown in FIG. 6 stores information representing the cutting down time for cutting down the harvested crop and the turning over time for turning over one or more harvested crops. The elapsed time determination unit 170 determines the elapsed time from the cutting down time and the turning over time, and updates the work status based on the determined elapsed time. Here, the elapsed time may represent the amount of sunshine from the cutting down time or the turning over time.

[0066] The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be arbitrarily modified and / or combined as long as the functionality is not impaired. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the required functionality can be realized. For example, some or all of the processing of the work management device 100 may be executed by the terminal 200. Furthermore, some or all of the processing of the terminal 200 may be executed by the work management device 100.

[0067] For example, the elapsed time determination unit 170 of the task management apparatus 100 may be implemented by the terminal 200. In this case, the elapsed time determination unit 170 does not need to update the "status" of the task data 410 in step S130 shown in FIG. 10 . The task management program 430 may include a display program 440. Furthermore, the output unit 180 of the task management apparatus 100 may be implemented by the terminal 200. In this case, the output unit 180 of the terminal 200 outputs progress information to the display unit 250.

[0068] Furthermore, the work management system 1000 may not include the terminal 200, and may display progress information on an external terminal that is not included in the work management system 1000. The progress information may include any combination of the quantity of remaining groups left in the field 500, the quantity of harvested crop groups discharged to the field 500, and the elapsed time since the discharge of the remaining groups, or may include only one of them.
