[0018] (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 device 100 and a terminal 200. The work management device 100 is communicatively connected to the terminal 200 and at least one or more work devices 30 via a network 20, for example, the Internet.

[0019] The working device 30 performs agricultural work by moving within the farm field 500. The working device 30 includes, for example, a tractor equipped with various types of working machines, a harvesting machine such as a combine harvester, a sprayer that sprays pesticides such as a drone, and the like.

[0020] The operating device 30 outputs operation information at each time to the operation management device 100. The operation information includes, for example, position information indicating the position of the operating device 30 at each time. The operating device 30 includes a positioning device that measures the position at each time, such as a GNSS (Global Navigation Satellite System) receiver or a quantum compass. The operating device 30 measures its own position at a predetermined interval, for example, at 10 second intervals, and obtains position information indicating the measured time and its own position in association with each other.

[0021] The operation information also includes status information indicating the state of the working implement 30 when working in the field 500, such as the speed, steering angle, engine RPM, and ON / OFF status of various clutches at each time of the working implement 30. When the working implement 30 is a vehicle that tows a working machine, such as a tractor, the operation information may also include information such as the PTO (power take-off) RPM when transmitting power to the working machine, and the hitch height and lift arm angle indicating the attitude of the working machine. For example, the working implement 30 measures its own status at a predetermined interval, such as every 10 seconds, and obtains status information indicating the time of measurement in association with the state of the working implement.

[0022] The work management apparatus 100 determines the working status of the work apparatus 30 at each time, for example, working, moving, stopped, not working, etc., based on the operation information of the work apparatus 30. Furthermore, the work management apparatus 100 determines the furrow on which the work apparatus 30 is working at each time, based on the position information of the work apparatus 30. The working status indicates an overview of the working status of the work apparatus 30, and indicates a classification according to, for example, whether or not the work apparatus 30 is working and the speed of the work apparatus 30. For example, working indicates that the work apparatus 30 was performing farm work, and moving indicates that the work apparatus 30 was moving without performing farm work. Stopped indicates that the drive device of the work apparatus 30, for example, the engine, was stopped while running, and not working indicates that the drive device of the work apparatus 30 was stopped.

[0023] The terminal 200 displays the operating status of the working device 30 in association with the ridge on which work is being performed at each time. For example, as shown in Fig. 2, the terminal 200 displays a display image 400 showing the operating status of the working device 30 in association with the ridge 510 being worked on at each time. This allows a user, such as a worker or the owner of the field 500, to easily grasp the ridge 510 on which the working device 30 has worked at each time.

[0024] (Work management system configuration) The configuration of the work management apparatus 100 included in the work management system 1000 will be described. As shown in FIG. 3, the work management apparatus 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management apparatus 100 is, for example, a computer including a cloud server. Information for the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 outputs the results of the processing executed by the calculation device 120. The input / output device 110 includes various input devices and output devices, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like. The input / output device 110 may be omitted.

[0025] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers operation information acquired from the maintenance device 30 to the arithmetic device 120. The communication device 130 also transfers signals generated by the arithmetic 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).

[0026] The storage device 140 stores various data, such as farm field data 310, for determining the operating status of the work device 30 and the ridges 510 on which work has been performed at each time, and the work management program 320. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 320. The work management program 320 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.

[0027] The farm field data 310 stores ridge information about ridges 510 provided in the farm field 500. The ridge information represents, for example, the position of the ridge 510. For example, the ridge information may represent a line connecting both ends of the ridge 510, such as a straight line segment, or may represent the area of ​​the ridge 510.

[0028] The arithmetic device 120 reads out and executes the work management program 320 from the storage device 140, and performs various data processing to determine the operating status of the work device 30 and the ridges 510 on which the work has been performed. For example, the arithmetic device 120 includes a central processing unit (CPU) and the like.

[0029] The arithmetic device 120 reads and executes the work management program 320, thereby realizing an operating status determination unit 150, a ridge determination unit 160, and an output unit 170, as shown in FIG. 4. The operating status determination unit 150 determines the operating status of the working device 30 at each time, for example, working, moving, stopped, not working, etc., based on the operating information of the working device 30. The ridge determination unit 160 determines the ridge 510 on which the working device 30 has performed work at each time. The output unit 170 outputs work information representing the operating status of the working device 30 in association with the ridge 510 on which the work has been performed at each time. The work information represents, for example, a display image 400 representing the operating status of the working device 30 in association with the ridge 510 on which the work has been performed at each time, as shown in FIG. 2.

[0030] Next, the configuration of the terminal 200 will be described. As shown in FIG. 5, the terminal 200 includes an input / output device 210, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

[0031] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. 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).

[0032] The storage device 240 stores various data, such as a display program 330, for displaying on the input / output device 210 of the terminal 200 work information representing the working status of the working device 30 in association with the ridges 510 on which the work has been performed at each time. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 330. The display program 330 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.

[0033] The arithmetic device 220 reads and executes the display program 330 to perform various data processing for displaying the work information acquired from the work management device 100. The arithmetic device 220 includes, for example, a central processing unit (CPU) and the like.

[0034] When the arithmetic device 220 reads and executes the display program 330, it cooperates with the input / output device 210 to realize the display unit 250 as shown in Fig. 4. The display unit 250 acquires work information from the work management apparatus 100, and displays a display image 400 representing the work information.

[0035] (Operation of the work management system) A method in which the work management system 1000 determines work information will be described. As shown in Fig. 1, the work device 30 outputs operation information to the work management device 100. For example, when a drive device, such as an engine or an electric motor, is stopped, the work device 30 outputs operation information from when the drive device is started to when it is stopped to the work management device 100. The work device 30 may sequentially output operation information to the work management device 100 while it is operating.

[0036] When the arithmetic device 120 of the work management apparatus 100 receives operation information from the work device 30, it reads and executes the work management program 320, and starts the processing shown in Fig. 6 which is a work management method. In step S110, the operation status determination unit 150 realized by the arithmetic device 120 determines the operation status of the work device 30 at each time, based on the operation information of the work device 30.

[0037] For example, the operating status determination unit 150 determines the operating status of the working apparatus 30 at each time based on the speed of the working apparatus 30 represented in the operation information. For example, when the speed of the working apparatus 30 is greater than a first threshold, the operating status determination unit 150 determines that the working apparatus 30 was moving (moving) at the time represented in the operation information, for example, the time when the speed of the working apparatus 30 was measured. Furthermore, when the speed of the working apparatus 30 is equal to or less than the first threshold and greater than a second threshold, the operating status determination unit 150 determines that the working apparatus 30 was performing work (working) at the time represented in the operation information. When the speed of the working apparatus 30 is equal to or less than the second threshold, the operating status determination unit 150 determines that the working apparatus 30 was stopped (stopped) at the time represented in the operation information. The operating status determination unit 150 determines that the working apparatus 30 was not operating (not operating) at a time when the working apparatus 30 did not acquire operation information. The speed of the working apparatus 30 may be included in the status information of the working apparatus 30, or may be determined from the position information of the working apparatus 30. For example, the speed of the working apparatus 30 may be determined based on the distance between two measured positions and the interval between the measured times in two pieces of position information where the measured times are adjacent to each other.

[0038] In step S120, the ridge determination unit 160 determines the ridge 510 on which work is being performed at each time based on the position information included in the operation information of the working device 30. For example, the ridge determination unit 160 acquires ridge information indicating the position of the ridge 510 in the field 500 from the field data 310. The ridge determination unit 160 determines that work is being performed on a ridge 510 that is a predetermined distance, for example, 20 cm or less, from the position of the working device 30 at each time. The ridge determination unit 160 may also determine a ridge 510 that is a predetermined distance or less from the position of the working device 30 for a predetermined period of time, for example, one continuous minute or more, as a ridge 510 on which the working device 30 is performing work. When the ridge information represents an area of ​​the ridge 510, the ridge determination unit 160 may determine, at each time, the ridge 510 that includes the position of the working device 30 as the ridge 510 where work is being performed. The ridge determination unit 160 may also determine, as the ridge 510 where work is being performed, the ridge 510 that includes the position of the working device 30 for a predetermined continuous period of time or more.

[0039] In step S130, the output unit 170 outputs work information indicating the operating status of the working device 30 and the ridge 510 on which work is being performed at each time to the terminal 200. The work information indicates, for example, a display image 400 indicating the operating status of the working device 30 and the ridge 510 on which work is being performed in association with each other at each time, as shown in Fig. 2. The display image 400 has, for example, a work information display area 410 and a ridge information display area 480.

[0040] The work information display area 410 displays information relating the operating status of the working device 30 and the ridge 510 on which work is being performed at each time. For example, the work information display area 410 displays each time in a band shape, and the operating status of the working device 30 at each time and the ridge 510 on which work is being performed are displayed in a identifiable manner at a position corresponding to the position at which each time is displayed. The work information display area 410 has, for example, a time display area 420 that displays each time, an operating status display area 430 that displays the operating status of the working device 30, and a worked ridge display area 440 that displays the ridge 510 being worked on.

[0041] In the example shown in FIG. 2, the time from 7:00 to 19:00 is displayed in a band shape in the time display area 420. In the operation status display area 430, the operation status of the working device 30 at that time, for example, working, moving, stopped, not working, etc., is displayed according to the position where the time is displayed in the time display area 420. For example, below the position of the time displayed in the time display area 420, an area in a display format showing the operation status of the working device 30 at that time is displayed. For example, when the working device 30 is working in the period from 7:10 to 8:15, a working display area 431 showing that the working device 30 is working is displayed below the position showing the period from 7:10 to 8:15 in the time display area 420. Also, in the example shown in FIG. 2, an area showing that the working device 30 is moving is displayed below the position showing the period from 8:15 to 8:25 in the time display area 420. In addition, an area indicating that the work device 30 is stopped is displayed below the position indicating the period from 11:50 to 12:15 in the time display area 420. An area indicating that the work device 30 is not operating is displayed below the position indicating the period from 12:15 to 12:30 in the time display area 420.

[0042] The worked ridge display area 440 displays the ridge 510 on which work was performed at that time according to the position where the time is displayed in the time display area 420. The worked ridge display area 440 displays, for example, work time information 441 indicating the period during which work was performed on the ridge 510, and ridge identification information 442 indicating the ridge 510 on which work was performed, such as an identifier representing the ridge 510. For example, the work time information 441 is displayed as an area in a display format representing the ridge 510 below the position indicating the time when work was performed on the ridge 510 in the time display area 420. For example, when work was performed on the first ridge 510-1 in the period from 7:10 to 8:15, the area representing the first ridge 510-1 is displayed as work time information 441 below the position indicating the period from 7:10 to 8:15 in the time display area 420. Furthermore, ridge identification information 442 indicating the ridge 510 on which work was performed, for example a number indicating the ridge 510, is displayed at a position corresponding to the work time information 441. For example, the ridge identification information 442 is displayed adjacent to the position at which the work time information 441 is displayed. For example, the ridge identification information 442 is displayed below the position at which the work time information 441 is displayed.

[0043] The ridge information display area 480 displays the position of the ridge 510 in the field 500, which is represented by the work time information 441 and the ridge identification information 442. For example, the ridge information display area 480 displays the field 500, the position of the ridge 510 in the field 500, and the ridge identifier 520 of the ridge 510 on a map. For example, the ridge 510 is displayed in a display format different from that of the other ridges 510, such as a color, pattern, line type, etc. For example, the ridge 510 displayed in the ridge information display area 480 is displayed in the same display format as the work time information 441 in the work ridge display area 440. Furthermore, the ridge identifier 520 displayed in the ridge information display area 480 is displayed in the same notation, such as characters, as the ridge identification information 442 in the work ridge display area 440.

[0044] Therefore, the display image 400 shown in FIG. 2 indicates that the work implement 30 was working on the second ridge 510-2 from 9:45 to 10:50.

[0045] In this way, the work information output from the output section 170 to the terminal 200 may represent a display image 400 that shows, at each time, the operating status of the work implement 30 in association with the ridge 510 on which work is being performed.

[0046] 6, the display unit 250 of the terminal 200 displays the work information acquired from the work management apparatus 100 on the input / output device 210. For example, as shown in FIG 2, the display unit 250 displays a display image 400 showing the operation information of the work apparatus 30 at each time in association with the ridges 510 on which the work was performed at each time.

[0047] By viewing the work information displayed on the input / output device 210, such as the display image 400, the user can easily check the ridge 510 on which the work device 30 was working at each time and the operating status of the work device 30 at that time.

[0048] (Embodiment 2) The working device 30 may be accompanied by a following device 40, as shown in Fig. 7. For example, when the working device 30 harvests crops, the harvested crops are loaded from the working device 30 onto the following device 40, such as a transport vehicle, which follows the working device 30. When the loaded harvested crops reach a load capacity that the following device 40 can carry, the following device 40 leaves the working device 30 and transports the harvested crops to a predetermined location, such as a post-harvest factory.

[0049] As shown in FIG. 8, the work management system 1000 may display, at each time, the operation status of the work device 30, the ridge 510 on which the work was performed, and the follower device 40 following the work device 30. In other words, the work management system 1000 may display, at each time, the operation status of the work device 30, the ridge 510 on which the work was performed, and the period during which the follower device 40 follows the work device 30. The user can check, at each time, the follower device 40 following the work device 30 and the ridge 510 on which the work was performed. For example, this allows the user to easily estimate the amount of crops loaded on the follower device 40 by checking the ridge 510 on which the work device 30 was performed while the follower device 40 was following.

[0050] Here, the tracking device 40 includes a positioning device that measures the position at each time, such as a GNSS (Global Navigation Satellite System) receiver, a quantum compass, etc. Position information indicating the measured position of the tracking device 40 is output from the tracking device 40 to the work management device 100.

[0051] (Work management system configuration) The configuration of the work management system 1000 is the same as that of the first embodiment, except that the work management apparatus 100 executes the work management program 320 to realize the following apparatus determination unit 180 as shown in Fig. 9. For this reason, detailed explanations will be omitted except for the following apparatus determination unit 180. The following apparatus determination unit 180 determines the following apparatus 40 that is following the work apparatus 30 at each time, based on the position information of the work apparatus 30 and the position information of the following apparatus 40.

[0052] (Operation of the work management system) A method in which the work management system 1000 determines the work information will be described. As in the first embodiment, the work device 30 outputs operation information to the work management device 100. In addition, the tracking device 40 outputs position information to the work management device 100. For example, the tracking device 40 sequentially outputs position information to the work management device 100 while operating. In addition, when a drive device, such as an engine or an electric motor, is stopped, the tracking device 40 may output position information from when the drive device is started to when it is stopped to the work management device 100.

[0053] When the arithmetic device 120 of the work management apparatus 100 receives operation information from the work device 30 and position information from the tracking device 40, it reads and executes the work management program 320 and starts the processing shown in Fig. 10 which is a work management method. The processing of steps S110 and S120 is the same as in the first embodiment, and therefore description thereof will be omitted.

[0054] In step S125, the following device determination unit 180 determines the following device 40 following the working device 30 at each time based on the position information of the working device 30 and the position information of the following device 40. For example, the following device determination unit 180 determines the following device 40 that is a predetermined distance, for example, 3 m or less, from the position of the working device 30 at each time as the following device 40 following the working device 30. The following device determination unit 180 may also determine the following device 40 that is a predetermined distance or less from the position of the working device 30 for a predetermined period of time, for example, one minute or more, as the following device 40 following the working device 30.

[0055] In step S130B, the output unit 170 outputs to the terminal 200 work information indicating the operating status of the working device 30, the ridge 510 on which work is being performed, and the follow-up device 40 following the working device 30 at each time. The work information indicates, for example, a display image 400B indicating the operating status of the working device 30 in association with the ridge 510 on which work is being performed at each time, as shown in FIG. 8. The display image 400B has, for example, a work information display area 410B and a ridge information display area 480. The ridge information display area 480 is the same as in embodiment 1, and therefore description thereof will be omitted.

[0056] The work information display area 410B displays information relating the operation status of the work device 30, the ridge 510 on which work is being performed, and the follow-up device 40 following the work device 30 at each time. For example, the work information display area 410B displays each time in a band shape, and the operation status of the work device 30 at each time, the ridge 510 on which work is being performed, and the follow-up device 40 following the work device 30 are displayed in an identifiable manner at the position where each time is displayed. The work information display area 410B has, for example, a time display area 420, an operation status display area 430, a work ridge display area 440, and a follow-up device display area 450. The time display area 420 and the operation status display area 430 are the same as those in the first embodiment, so their explanations will be omitted.

[0057] The following device display area 450 displays the following device 40 following the working device 30 at each time. In the example shown in FIG. 8, the following device display area 450 displays the following device 40 following the working device 30 at that time according to the position where the time is displayed in the time display area 420. The following device display area 450 displays, for example, following time information 451 indicating the period during which the working device 30 is being followed, and following device identification information 452 indicating the following following device 40, for example the name of the following device 40 (first vehicle). For example, the following time information 451 is displayed as an area in a display format indicating that the following device 40 is following, below the position indicating the time during which the following device 40 is following the working device 30 in the time display area 420. For example, when the following device 40, e.g. the first vehicle, is following the working device 30 during the period from 7:10 to 7:50, an area representing the following of the following device 40 is displayed as following time information 451 below the position representing the period from 7:10 to 7:50 in the following device display area 450.

[0058] When multiple following devices 40 are following the working device 30, the following devices 40 following the working device 30 are displayed in an identifiable manner in the following device display area 450. For example, in the vertical direction, the periods during which each following device 40 is following are displayed at different positions. For example, the period during which a second following device 40, for example, a second vehicle, is following the working device 30 is displayed below the position representing the period during which a first following device 40, for example, a first vehicle, is following the working device 30.

[0059] In this way, the work information output from the output unit 170 to the terminal 200 may represent a display image 400B that shows, at each time, the operating status of the work device 30, the ridge 510 on which work is being performed, and the following device 40 that is following the work device 30 in association with each other.

[0060] 10, similarly to the first embodiment, display unit 250 of terminal 200 displays the work information acquired from work management apparatus 100 on input / output device 210. For example, as shown in FIG 8, display unit 250 displays display image 400B which shows, in association with each other, operation information of work apparatus 30 at each time, ridge 510 on which work was performed at each time, and follow-up device 40 following work apparatus 30 at each time.

[0061] By viewing the work information displayed on the input / output device 210, such as the display image 400B, the user can easily confirm at each time the ridge 510 on which the work device 30 performed work and the following device 40 that was following the work device 30 at that time.

[0062] (Modification) The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not impair the function. For example, in step S110 shown in FIG. 6 or FIG. 10, the operation status determination unit 150 of the work management apparatus 100 may determine the operation status of the working device 30, such as working, moving, stopped, not working, etc., in any manner based on the operation information. For example, when the speed of the working device 30 is greater than the second threshold, the operation status determination unit 150 may distinguish between working and moving based on the attitude of the working machine, such as the hitch height and lift arm angle. In addition, the operation status determination unit 150 may distinguish between working and moving based on the PTO rotation speed.

[0063] 6 or 10, the classification of the operating status determined may be arbitrarily selected so as to represent an overview of the status in which the working apparatus 30 is operating. For example, the operating status represents at least one of the classifications of whether the working apparatus 30 is operating or not and the speed of the working apparatus 30. For example, the operating status may be classified as operating and not operating, or as working and other.

[0064] Also, in step S120 shown in FIG. 6 or FIG. 10, the ridge determination unit 160 of the work management apparatus 100 may use any method based on the position information of the work apparatus 30 to determine the ridge 510 on which the work apparatus 30 is working at each time. For example, the ridge determination unit 160 may determine the closest ridge 510 among the ridges 510 that are a predetermined distance, for example, 1 m or less, from the position of the work apparatus 30 as the ridge 510 on which work is being performed. Furthermore, when the interval between times when work is being performed on the same ridge 510 is a predetermined period, for example, 1 minute or less, the ridge determination unit 160 may determine that work is being performed on that ridge 510 during that period. Furthermore, the ridge determination unit 160 may extract operation information indicating that the work apparatus 30 is working, and determine the ridge 510 on which work is being performed for the time corresponding to the extracted operation information.

[0065] 10, the following device determination unit 180 of the task management apparatus 100 may determine the following device 40 following the task apparatus 30 by any method based on the position information of the task apparatus 30 and the position information of the following device 40. For example, the following device determination unit 180 may determine the following device 40 closest to the task apparatus 30 among the following devices 40 whose distance from the task apparatus 30 is a predetermined distance, for example, 10 m or less, as the following device 40 following the task apparatus 30. Furthermore, when the time interval during which the same following device 40 follows the task apparatus 30 is a predetermined period, for example, 1 minute or less, the following device determination unit 180 may determine that the following device 40 is following the task apparatus 30 during that period. In addition, the following device determination unit 180 may extract operation information indicating that the maintenance device 30 is performing work, and determine the following device 40 that is following the maintenance device 30 for the time corresponding to the extracted operation information.

[0066] The ridge identification information 442 shown in FIG. 2 or FIG. 8 may include information representing the field 500, for example, the name of the field 500. For example, in the work ridge display area 440, information representing the field 500 in which the ridge 510 is established, for example, the name of the field 500, may be displayed adjacent to information representing the ridge 510 in which work has been performed, for example, the number. Also, information representing the field 500 in which the ridge 510 is established may be displayed at the left end of the work ridge display area 440. In this case, for example, when displaying ridges 510 in which work has been performed in a plurality of fields 500, the information representing the ridge 510 and the tracking time information 451 may be displayed at a position corresponding to the field 500 in which the ridge 510 is established. For example, in the vertical direction, the periods in which work was performed on the ridges 510 established in each field 500 are displayed at different positions from each other. For example, below a position showing a period during which work was performed on a ridge 510 provided in one farm field 500, a period during which work was performed on a ridge 510 provided in another farm field 500 is shown.

[0067] Also, in step S130 shown in FIG. 6, the output unit 170 of the work management apparatus 100 may output to the terminal 200 work information representing, in any format, the operating status of the working apparatus 30 and the ridge 510 on which the work is being performed at each time. For example, the work information may be represented as a graph representing the operating status of the working apparatus 30 and the ridge 510 on which the work is being performed at each time, as shown in FIG. 11. For example, the work information may be represented by a line graph representing the operating status of the working apparatus 30 at each time and the ridge 510 on which the work is being performed at each time. In this case, the display unit 250 of the terminal 200 displays an image representing the graph shown in FIG. 11 in the work information display area 410 shown in FIG. 2.

[0068] 10, the output unit 170 may also output to the terminal 200 work information representing, in any format, the operating status of the working device 30, the ridge 510 on which work is being performed, and the follow-up device 40 following the working device 30 at each time. The output unit 170 may also output to the terminal 200 work information representing, in association with two of the operating status of the working device 30, the ridge 510 on which work is being performed, and the follow-up device 40 following the working device 30 at each time.

[0069] Furthermore, the work information output by the output section 170 of the work management apparatus 100 does not have to represent the display images 400, 400B shown in Fig. 2 or 8. For example, the display section 250 of the terminal 200 may generate the configurations of the display images 400, 400B based on the work information.

[0070] In step S125 shown in FIG. 10, when the operation information of the working device 30 includes harvest information indicating the harvest amount of the crop, the following device determination unit 180 may determine the amount of the crop stored in the following device 40 following the working device 30 based on the operation information. For example, the following device determination unit 180 determines the amount of the crop harvested by the working device 30 during the period in which the following device 40 follows the working device 30 as the amount of the crop stored in the following device 40. The information indicating the amount of the crop stored in the following device 40 is included in the work information and output to the terminal 200. For example, the display image 400B represented by the work information may display the amount of the crop stored in the following device 40 at a position corresponding to the following time information 451 indicating the period during which the following device 40 followed. For example, the display image 400B may show the harvest volume stored in the tracking device 40 adjacent to tracking time information 451 indicating the period of tracking by the tracking device 40. For example, in the display image 400B, the harvest volume stored in the tracking device 40 may be shown adjacent to the lower or upper side of the tracking time information 451.

[0071] The above-described embodiment and modified examples are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily changed and / or arbitrarily combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, some or all of the processing in the terminal 200 may be executed by the work management device 100. Furthermore, some or all of the processing in the work management device 100 may be executed by the terminal 200. Furthermore, the work management program 320 may include a display program 330.

[0072] Furthermore, the work management system 1000 may not include the terminal 200, and may display work information on an external terminal that is not included in the work management system 1000.
