Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when the field is large, the agricultural work vehicle may require multiple days to complete the work in one field. In this case, it is difficult to grasp the detailed progress status of the work in the field, such as predicting the time when the work in the field will be completed, just by representing the movement trajectory that the agricultural work vehicle has moved so far.

[0006] In view of the above situation, one of the purposes of the present disclosure is to assist the user in grasping the detailed progress status of the work by distinguishing and representing the area where the work was performed in the past and the area where the work was performed in the most recent predetermined period. Other purposes can be understood from the following description and the explanation of the embodiments. [Means for solving the problem]

[0007] The means for solving the problem are described below using the numbers and symbols used in the embodiments for carrying out the invention. These numbers and symbols are added in parentheses for reference to show an example of the correspondence between the claims and the embodiments for carrying out the invention. Therefore, the claims should not be interpreted restrictively because of the parenthetical statements.

[0008] A work management method according to one embodiment for achieving the above objective includes determining a recent trajectory (620) representing the trajectory of one or more work devices (30) during a recent period, based on the operation information of one or more work devices (30) during a recent period, which represents a predetermined period in the most recent time. The work management method also includes outputting image information showing a progress image (600) that represents the recent trajectory (620) of one or more work devices (30) and work volume information representing the amount of work performed by one or more work devices (30) before the recent period.

[0009] A work management system (1000) according to one embodiment for achieving the above objective comprises a trajectory determination unit (160) and an output unit (180). The trajectory determination unit (160) determines the most recent trajectory (620) representing the trajectory of one or more work devices (30) in the most recent period, based on the operation information of one or more work devices (30) in the most recent period, which represents the most recent predetermined period. The output unit (180) outputs image information showing a progress image (600) that represents the most recent trajectory (620) of one or more work devices (30) and work amount information representing the amount of work performed by one or more work devices (30) before the most recent period.

[0010] A work management program (420) according to one embodiment for achieving the above objective causes the arithmetic units (120, 220) to determine the most recent trajectory (620) representing the trajectory of one or more work devices (30) during the most recent period, based on the operation information of one or more work devices (30) during the most recent period, which represents a predetermined period in the most recent time. The work management program (420) also causes the arithmetic units (120, 220) to output image information showing a progress image (600) that represents the most recent trajectory (620) of one or more work devices (30) and work amount information representing the amount of work performed by one or more work devices (30) before the most recent period. [Effects of the Invention]

[0011] According to the above configuration, users can gain a more detailed understanding of the progress of their work. [Brief explanation of the drawing]

[Figure 6] This flowchart shows the process by which a work management system in one embodiment determines the amount of work performed in a period prior to the most recent one. [Figure 7] This is a flowchart illustrating the process by which a work management system in one embodiment displays progress images on a terminal. [Modes for carrying out the invention]

[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 Figure 1, the work management system 1000 comprises a work management device 100 and a terminal 200. The work management device 100 is communicated with the terminal 200 and one or more work devices 30 via a network 20, for example, the Internet.

[0014] The work device 30 performs tasks such as tilling, planting, and harvesting while moving around in the field. The work device 30 includes, for example, a tractor that tows work machinery to perform tasks in the field, a harvester and planter integrated with the work machinery, a drone for spraying pesticides, and a truck for collecting harvested produce. When the work device 30 is working in the field, it transmits operational information at each moment to the work management device 100. For example, the operational information includes the location 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 a quantum compass, and acquires location information representing the position of the work device 30 at each moment it has moved. The operational information may also include, for example, status information representing the state of each machine of the work device 30, such as the ON / OFF status of various clutches. Furthermore, when the work device 30 is a vehicle that tows a work machine, such as a tractor, the status information may include information such as the PTO (power take-off) rotation speed when transmitting power to the work machine, and hitch height and lift arm angle indicating the posture of the work machine.

[0015] The work management device 100 determines the amount of work performed by the work devices 30, such as the work area, based on operational information, such as location information, obtained from one or more work devices 30. For example, the work management device 100 determines the amount of work performed by one or more work devices 30, such as the work area, before the most recent predetermined period, such as the most recent period representing today.

[0016] Further, the work management device 100 determines a recent trajectory representing the trajectories of one or more work devices 30 in the recent period based on the operation information acquired from one or more work devices 30 in the recent period, such as position information. The work management device 100 outputs image information indicating an image showing the determined recent trajectory and the work amount information representing the work amount of the work performed by one or more work devices 30 before the recent period to the terminal 200.

[0017] The terminal 200 displays a progress image 600 representing the recent trajectory and the work amount information. For example, as shown in FIG. 2, the progress image 600 represents the recent trajectory 620 and the work amount information, such as the work area 610, on a map. For example, the work area 610 represents the area where work was performed by the work device 30 before the recent period, for example, before the previous day. The recent trajectory 620 represents the trajectory along which the work device 30 moved during the recent period, for example, on the current day. The recent trajectory 620 is updated at a predetermined interval, for example, every minute, based on the position information acquired from the work device 30. A user, such as the owner of the farmland 500 or the manager of the work, can check the progress status in each farmland 500 by viewing the progress image 600.

[0018] For example, by viewing the progress image 600, the user can confirm that the work in the first farmland 500-1 has been completed for the area represented by the work area 610 and the area represented by the recent trajectory 620 before the recent period. In this way, the work management system 1000 supports the user in checking the detailed progress of the work.

[0019] (Configuration of Work Management System) 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. 3, the work management device 100 includes an input / output device 110, an arithmetic device 120, a communication device 130, and a storage device 140. The work management device 100 is a computer including, for example, a cloud server or the like. Information for the arithmetic device 120 to execute processing is input to the input / output device 110. Also, the input / output device 110 outputs the result of the processing executed by the arithmetic device 120. The input / output device 110 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. The input / output device 110 may be omitted.

[0020] 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 the operation information acquired from the work device 30 to the arithmetic device 120. Also, it transfers the signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces such as, for example, a NIC (Network Interface Card), a USB (Universal Serial Bus), and the like.

[0021] The storage device 140 stores various data for determining the most recent trajectory 620 of the work device 30 in the most recent period and the work amount of the work device 30 before the most recent period, for example, the work area 610, such as the field data 400, the work data 410, and the work management program 420. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 420. The work management program 420 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.

[0022] The field data 400 stores information about the field 500 on which work is performed by the work device 30. For example, the field data 400 represents the location and shape of one or more fields 500. For example, field information about the field 500, such as location and shape, is pre-registered by the user. For example, the user inputs information about the field 500, such as location and shape, into the terminal 200. For example, the user inputs the shape of the field 500 on a map displayed on the terminal 200. The terminal 200 outputs the information about the field 500 to the work management device 100. Alternatively, the information about the field 500 may be extracted based on images of the field 500 taken from above.

[0023] The work data 410 stores work volume information representing the amount of work performed by the work device 30 in the period prior to the most recent period, for example, work area 610. For example, the work data 410 stores work volume information representing the amount of work performed in the current season. Here, the season represents the period from when agricultural products were harvested in the field 500 until the next harvest. For example, the current season represents the period from when agricultural products were most recently harvested in the field 500 to the present. Alternatively, the current season may represent the period from when agricultural products were most recently harvested in the field 500 until the next harvest. Furthermore, previous seasons represent the period prior to when agricultural products were most recently harvested in the field 500. The work data 410 may also store information representing the type of work performed by the work device 30, such as tilling, planting, harvesting, etc., in association with the work volume information. The work data 410 may also store operating information of the work device 30.

[0024] The arithmetic unit 120 executes the work management program 420 and performs various data processing to determine the most recent trajectory 620 of the work device 30 in the most recent period and the amount of work performed by the work device 30 prior to the most recent period, such as the work area 610. For example, the arithmetic unit 120 includes a central processing unit (CPU).

[0025] The arithmetic unit 120 reads and executes the work management program 420 to realize a work determination unit 150, a trajectory determination unit 160, a work field determination unit 170, and an output unit 180, as shown in Figure 4. The work determination unit 150 determines the amount of work performed by the work device 30, for example, the work area 610, at predetermined intervals, for example, at predetermined times each day, based on the operation information of the work device 30. The trajectory determination unit 160 determines the most recent trajectory 620, which represents the trajectory of the work device 30 during the most recent period, based on the position information of the work device 30 during the most recent period. The work field determination unit 170 determines the field 500 in which the work device 30 performed work during the most recent period. The output unit 180 outputs image information showing the most recent trajectory 620 and a progress image 600 representing the amount of work to the terminal 200.

[0026] Next, the configuration of terminal 200 will be described. As shown in Figure 5, terminal 200 comprises an input / output device 210, an arithmetic unit 220, a communication device 230, and a storage device 240. Terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information for the arithmetic unit 220 to perform processing is input to the input / output device 210. The input / output device 210 also outputs the results of the processing performed by the arithmetic unit 220. The input / output device 210 includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, touch panel, etc.

[0027] 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 computing device 220. It also transfers signals generated by the computing device 220 to the work management device 100. The communication device 230 includes various interfaces such as transceivers used for wireless communication, such as wireless LAN (Local Area Network) and cellular networks, NIC (Network Interface Card), and USB (Universal Serial Bus).

[0028] The storage device 240 stores various data for displaying image information acquired from the work management device 100, such as a display program 430. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 430. The display program 430 may be provided as a computer program product recorded on a computer-readable storage medium 2, or as a computer program product downloadable from a server.

[0029] The arithmetic unit 220 executes the display program 430 and performs various data processing to display the image information acquired from the work management device 100. For example, the arithmetic unit 220 includes a central processing unit (CPU).

[0030] The arithmetic unit 220 reads and executes the display program 430, and in cooperation with the input / output device 210, realizes the display unit 250 as shown in Figure 4. The display unit 250 displays image information acquired from the work management device 100.

[0031] (Operation of the work management device) First, we will explain the operation of the work management device 100, which determines the amount of work, for example, the work area 610, performed by one or more work devices 30 in the period prior to the most recent period, based on the operation information of the work devices 30. When a work device 30 is working in the field 500, it outputs operation information to the work management device 100. The work device 30 acquires operation information at predetermined intervals, for example, every 10 seconds. The work device 30 outputs the acquired operation information to the work management device 100 sequentially. In addition, when the drive device, for example, the engine, stops, the work device 30 may output the operation information acquired from the start of the drive device until it stops to the work management device 100. The work management device 100 stores the acquired operation information in work data 410.

[0032] The calculation unit 120 of the work management device 100 executes the work management program 420 at predetermined intervals, for example, at a predetermined time each day. The work determination unit 150 determines the amount of work performed by the work device 30 in the most recent period, for example, before the most recent predetermined time, at predetermined intervals, for example, at a predetermined time each day. For example, the work determination unit 150 determines the amount of work performed before midnight on the current day when it reaches midnight each day. For example, the most recent period represents the period after the time when the calculation unit 120 most recently determined the amount of work, for example, the current day. By executing the work management program 420, the calculation unit 120 performs the processing shown in Figure 6, which is part of the work management method.

[0033] In step S110, the work determination unit 150, implemented by the calculation unit 120, determines a work period representing the time during which the work device 30 was performing work, based on the position information included in the operating information of the work device 30. For example, the work determination unit 150 determines the speed of the work device 30 at the position indicated in the position information, based on the position information of the work device 30, and determines the period during which the speed of the work device 30 falls within a predetermined range as the work period. The measured speed of the work device 30 at each position of the work device 30 is determined, for example, based on the distance between the positions of two adjacent work devices 30 and the interval between the measured times.

[0034] In step S120, the work determination unit 150 determines the amount of work performed by the work device 30, for example, the work area 610 in which the work device 30 performed work, based on the position information of the work device 30 during the work period. For example, the work determination unit 150 extracts the position of the work device 30 during the work period from the position information of the work device 30. The work determination unit 150 determines the convex hull for the position of the work device 30 during the work period as the work area 610. Alternatively, the work determination unit 150 may determine the work area 610 as an area obtained by expanding the convex hull by the working width of the work device 30.

[0035] Furthermore, the work determination unit 150 determines which fields 500 registered in the field data 400 have been worked on by the work device 30. For example, the work determination unit 150 determines that a field 500 including a work area 610 has been worked on by the work device 30. The work determination unit 150 stores area information representing the determined work area 610 as work volume information in the work data 410. The work determination unit 150 stores the work volume information in the work data 410 in association with the fields 500 on which work was performed by the work device 30.

[0036] In step S130, the work determination unit 150 determines the type of work performed during the work period, such as tilling, planting, or harvesting, based on the operating information of the work equipment 30 during the work period. For example, the work determination unit 150 determines the type of work using a trained model obtained by machine learning. In this case, the trained model is trained to estimate the type of work from the operating information. Alternatively, the trained model may be trained to estimate the type of work from the location information. The work determination unit 150 may also determine the type of work based on the model of the work equipment 30. In this case, the storage device 140 stores work-related data that associates the model of the work equipment 30 with the type of work. The work determination unit 150 determines the type of work based on the work-related data. The type of work may also be entered by the user into the terminal 200. In this case, the work determination unit 150 obtains information representing the type of work from the terminal 200. The type of work is stored in the work data 410 by the work determination unit 150 in association with the amount of work information.

[0037] In this way, the work management device 100 stores information regarding work performed by the work device 30 in the work data 410 for periods prior to the most recent period.

[0038] Next, we will explain the operation in which the work management system 1000 determines the most recent trajectory 620 of the work device 30 for the most recent period and displays the progress image 600 on the input / output device 210 of the terminal 200. The work device 30 sequentially outputs at least the position information from the acquired operational information to the work management system 100. When the arithmetic unit 120 of the work management system 100 receives the position information from the work device 30, it reads and executes the work management program 420. By executing the work management program 420, the arithmetic unit 120 performs the process shown in Figure 7, which is part of the work management method.

[0039] In step S210, the trajectory determination unit 160, implemented by the calculation unit 120, determines the most recent trajectory 620, which represents the trajectory of the work device 30 in the most recent period, based on the position information of the work device 30 in the most recent period. For example, the trajectory determination unit 160 extracts the position of the work device 30 measured in the most recent period from the position information of the work device 30. Alternatively, the trajectory determination unit 160 may extract the position of the work device 30 measured at intervals greater than the intervals in which the position of the work device 30 was measured in the most recent period, for example, at 1-minute intervals. The trajectory determination unit 160 determines the most recent trajectory 620 as a line connecting the extracted positions in the order of the measured times. For example, the trajectory determination unit 160 may determine the most recent trajectory 620 as a line connecting the extracted positions with straight line segments in the order of the measured times.

[0040] In step S220, the work field determination unit 170 determines the work field in which the work device 30 performed work in the most recent period, based on the position information of the work device 30. For example, based on the position information of the work device 30, the work field determination unit 170 determines the work field 500 in which the work device 30 has stayed continuously for a time threshold or longer in the most recent period. For example, the work field determination unit 170 determines the time at which the work device 30 was first included in the area of ​​field 500 as the entry time, which represents the time when the work device 30 entered field 500. The work field determination unit 170 determines field 500 as a work field when the positions of each work device 30 measured from the entry time to the time after the time threshold has elapsed are included in the area of ​​field 500. Furthermore, the work field determination unit 170 may determine a field 500 as a work field if the positions of each work device 30 measured from the time of entry to the time measured immediately after the time threshold has elapsed are included in the area of ​​field 500.

[0041] For example, in the example shown in Figure 2, the working device 30's position in the first field 500-1 and the second field 500-2, measured from the time of entry to the time after the time threshold has elapsed, is included in each field 500. Therefore, the working field determination unit 170 determines the first field 500-1 and the second field 500-2 as working fields. On the other hand, the working device 30 enters the third field 500-3 once to retrieve components, such as bags for agricultural products, that were placed there, but immediately exits and moves to the first field 500-1. Therefore, the period during which the working device 30 is in the third field 500-3 is less than the time threshold. Therefore, the work field determination unit 170 does not determine the third field 500-3 as a work field.

[0042] In step S230, the work determination unit 150 determines the type of work performed in the most recent period, such as tilling, planting, or harvesting. For example, the work determination unit 150 determines the type of work based on the model of the work device 30. In this case, the storage device 140 stores work-related data that associates the model of the work device 30 with the type of work. The work determination unit 150 determines the type of work based on the work-related data. Alternatively, similar to step S130 shown in Figure 6, the work determination unit 150 may determine the type of work performed in the most recent period based on the operating information of the work device 30 in the most recent period. The type of work may also be entered by the user into the input / output device 210 of the terminal 200.

[0043] In step S240 shown in Figure 7, the output unit 180 outputs image information to the terminal 200 showing the most recent trajectory 620 and a progress image 600 representing the amount of work information. The image information may be image data representing the most recent trajectory 620 and the amount of work information, or it may be data representing the composition of the image representing the most recent trajectory 620 and the amount of work information.

[0044] The progress image 600, for example as shown in Figure 2, displays one or more fields 500, work volume information, and the most recent trajectory 620 on a map. For example, the work volume information displayed in the progress image 600 includes area information representing the work area 610. The progress image 600 may also represent device position information 630, which represents the current position of the work device 30. The progress image 600 may also represent a starting position 640, which represents the position where the work device 30 started moving in the most recent period. For example, the most recent trajectory 620 is represented on the map by a line connecting the starting position 640 to the position represented in the device position information 630, along the trajectory of the work device 30.

[0045] The device location information 630 may represent the type of work device 30, for example, a tiller, planter, harvester, etc. For example, the device location information 630 may represent an image, for example, an icon, corresponding to the type of work device 30. The device location information 630 may also represent the type of work performed by the work device 30, for example, tilling, planting, harvesting, etc. For example, the device location information 630 may represent an image, for example, an icon, corresponding to the type of work.

[0046] In the example shown in Figure 2, the progress image 600 indicates that the work device 30 is currently located at the position indicated by the device position information 630 on the map. The progress image 600 also indicates that, in the most recent period, the work device 30 has moved along the most recent trajectory 620 connecting the starting position 640 to the position indicated by the device position information 630. Furthermore, the progress image 600 indicates that the work device 30 has performed work in the first field 500-1 and the second field 500-2 of the field 500. The first field 500-1 and the second field 500-2 may be distinguished from the other fields 500 by a display format such as color or pattern. Furthermore, the progress image 600 may represent only the first field 500-1 and the second field 500-2, which are the work fields, out of the total field 500. By distinguishing the work fields from the other fields 500, users can easily check the progress of the work in the most recent period.

[0047] The progress image 600 may represent only the amount of work performed in the work fields during the most recent period, for example, only the work area 610. For example, in the example shown in Figure 2, the work area 610 is represented only in the first field 500-1 and the second field 500-2, where work was performed during the most recent period. Therefore, the progress image 600 indicates that no work was performed in the second field 500-2 before the most recent period. Also, since no work was performed in the third field 500-3, the progress image 600 does not represent the work area 610 even if work was performed before the most recent period. As a result, the user is only shown the amount of work performed in the 500 fields during the most recent period, making it easy to grasp the progress status during the most recent period.

[0048] In step S250 shown in Figure 7, the display unit 250 of the terminal 200 displays image information acquired from the work management device 100 on the input / output device 210. For example, the display unit 250 displays the progress image 600 shown in Figure 2. By viewing the displayed image information, the user can check the detailed progress status of each field 500.

[0049] Furthermore, the progress image 600 displayed by the display unit 250 may include an area representing an operation menu 700. The operation menu 700 controls the information displayed in the progress image 600 based on user input. For example, the operation menu 700 includes an area representing a trajectory display button 710 that controls whether or not to display the most recent trajectory 620 in the progress image 600. For example, the operation menu 700 controls the progress image 600 so that the most recent trajectory 620 is not displayed when the slider of the trajectory display button 710 is slid to the left, and so that the most recent trajectory 620 is displayed when it is slid to the right.

[0050] For example, when the display unit 250 does not display the most recent trajectory 620, it receives trajectory display information indicating that the progress image 600 should display the most recent trajectory 620. For example, when the user slides the slider of the trajectory display button 710 to the right, the display unit 250 determines that it has received trajectory display information. Upon receiving trajectory display information, the display unit 250 outputs the trajectory display information to the work management device 100. Upon receiving trajectory display information, the output unit 180 of the work management device 100 outputs information about the most recent trajectory 620 to the terminal 200. Based on the acquired information, the display unit 250 of the terminal 200 displays the most recent trajectory 620 in the progress image 600.

[0051] Furthermore, the operation menu 700 may include an area for representing a field display button 712 that controls whether or not to display field 500 in the progress image 600. For example, the operation menu 700 may control whether or not to display field 500 in the progress image 600 when the slider of the field display button 712 is slid to the left, and whether or not to display field 500 when it is slid to the right. The field display button 712 may also control whether or not to display working fields, such as the first field 500-1 and the second field 500-2, in the progress image 600.

[0052] For example, if the progress image 600 does not show the area of ​​field 500, the display unit 250 receives field display information indicating that the progress image 600 should show the area of ​​field 500. For example, if the user slides the slider of the field display button 712 to the right, the display unit 250 determines that it has received field display information. Upon receiving the field display information, the display unit 250 outputs the field display information to the work management device 100. Upon receiving the field display information, the output unit 180 of the work management device 100 outputs the information of field 500 to the terminal 200. Based on the acquired information of field 500, the display unit 250 of the terminal 200 displays the area of ​​field 500 in the progress image 600.

[0053] Furthermore, the operation menu 700 may include an area for a work amount display button 711 that controls whether or not to display work amount information, such as the work area 610, in the progress image 600. For example, the operation menu 700 may control the progress image 600 so that work amount information is not displayed when the slider of the work amount display button 711 is slid to the left, and so that work amount information is displayed when it is slid to the right. Alternatively, the work amount display button 711 may be set so that it can only be slid to the right when the slider of the field display button 712 is slid to the right.

[0054] For example, when the progress image 600 does not display workload information, the display unit 250 receives workload display information indicating that workload information should be displayed in the progress image 600. For example, when the user slides the slider of the workload display button 711 to the right, the display unit 250 determines that it has received workload display information. Upon receiving workload display information, the display unit 250 outputs the workload display information to the work management device 100. Upon receiving the workload display information, the output unit 180 of the work management device 100 outputs the workload information to the terminal 200. Based on the acquired workload information, the display unit 250 of the terminal 200 displays the workload information in the progress image 600.

[0055] Furthermore, the operation menu 700 may include an area representing a display selection button 720 for selecting a work type to display the most recent trajectory 620 and work amount information, such as the work area 610, on the progress image 600. For example, the operation menu 700 may control the display selection button 720 so that when the slider is slid to the left, the most recent trajectory 620 and work amount information for the work type corresponding to that slider are not displayed. Also, the operation menu 700 may control the display selection button 720 so that when the slider is slid to the right, the most recent trajectory 620 and work amount information for the work type corresponding to that slider are displayed.

[0056] For example, when the slider for the "Tillage" display selection button 720 is slid to the right, the progress image 600 displays the most recent track 620 with the work type "Tillage" and the amount of work information. Conversely, when the slider for the "Tillage" display selection button 720 is slid to the left, the progress image 600 does not display the most recent track 620 with the work type "Tillage" and the amount of work information.

[0057] For example, when the slider for the "Planting" display selection button 720 is slid to the right, the progress image 600 displays the most recent trajectory 620 with the work type "Planting" and the amount of work information. Conversely, when the slider for the "Planting" display selection button 720 is slid to the left, the progress image 600 does not display the most recent trajectory 620 with the work type "Planting" and the amount of work information.

[0058] For example, when the slider for the "Harvest" display selection button 720 is slid to the right, the progress image 600 displays the most recent trajectory 620 for which the work type is "Harvest" and the amount of work information. Conversely, when the slider for the "Harvest" display selection button 720 is slid to the left, the progress image 600 does not display the most recent trajectory 620 for which the work type is "Harvest" and the amount of work information.

[0059] In this case, the display unit 250 receives selection information indicating the type of work that should represent either the most recent trajectory 620 or the workload information, or both, in the progress image 600. For example, when a user slides the slider of a display selection button 720 corresponding to a work type to the right, the display unit 250 determines that it has received selection information indicating the type of work corresponding to the slid display selection button 720. Upon receiving the selection information, the display unit 250 outputs the selection information to the work management device 100. Upon receiving the selection information, the output unit 180 of the work management device 100 outputs to the terminal 200 information representing the most recent trajectory 620 in which work of the work type indicated in the selection information was performed, and the workload information for work of the work type indicated in the selection information. The display unit 250 of the terminal 200 displays the acquired information in the progress image 600.

[0060] Furthermore, the display unit 250 receives hidden information indicating a work type that does not represent the most recent trajectory 620 and workload information in the progress image 600. For example, when a user slides the slider of a display selection button 720 corresponding to a work type to the left, the display unit 250 determines that it has received hidden information indicating the work type corresponding to the slid display selection button 720. Upon receiving hidden information, the display unit 250 displays the progress image 600 without showing the most recent trajectory 620 and workload information corresponding to the work type indicated in the hidden information. This allows the user to check the progress information for a specific work type in detail.

[0061] (modified version) The configuration described in the embodiment is just one example, and the configuration can be changed as long as it does not impair the function. For example, the progress image 600 shown in Figure 2 may represent the amount of work done in field 500 where no work has been done in the most recent period. In this case, if work has been done in the third field 500-3 prior to the most recent period, the amount of work done may be displayed.

[0062] For example, the work volume information displayed in the progress image 600 may include past trajectory information representing the trajectory of the work device 30 before the most recent period. For example, the past trajectory information represents the trajectory of the work device 30 before the most recent period in the current season. Alternatively, the past trajectory information may represent only the portion of the trajectory of the work device 30 before the most recent period in the current season that falls within the area of ​​field 500. Alternatively, the past trajectory information may represent only the portion of the trajectory of the work device 30 before the most recent period in the current season that falls within the area of ​​the work fields where the work device 30 performed work in the most recent period, for example, field 1 500-1 and field 2 500-2.

[0063] In this case, in step S120 shown in Figure 6, the work determination unit 150 of the work management device 100 determines past trajectory information representing the trajectory of the work device 30 based on the position information of the work device 30 prior to the most recent period. For example, the work determination unit 150 extracts the position represented in the position information of the work device 30 prior to the most recent period. Alternatively, the trajectory determination unit 160 may extract the position of the work device 30 measured at intervals greater than the interval at which the position of the work device 30 was measured, for example, at 1-minute intervals, from the position information of the work device 30 prior to the most recent period. The trajectory determination unit 160 determines the line connecting the extracted positions in the order of the measured times as the trajectory of the work device 30 prior to the most recent period. For example, the work determination unit 150 may determine the line connecting the extracted positions with straight line segments in the order of the measured times as the trajectory of the work device 30 prior to the most recent period.

[0064] Furthermore, if the past trajectory information represents only the trajectory of the work device 30 in the area included in the field 500, in step S120, the work determination unit 150 determines the past trajectory information based on the position information of the work device 30 during the work period determined in step S110. In this case, the work determination unit 150 determines the field 500 including the trajectory of the work device 30 as the field 500 in which work was performed by the work device 30.

[0065] Furthermore, the work volume information displayed in the progress image 600 shown in Figure 2 may represent the progress rate of the fields 500 where the work device 30 performed work prior to the most recent period. For example, the work volume information may represent the area of ​​the fields 500 where the work device 30 performed work prior to the most recent period in different display formats depending on the progress rate of those fields 500. For example, the work volume information may represent multiple groups of fields 500, classified based on the progress rate of the fields 500 and one or more thresholds, in an identifiable display format. For example, when the fields 500 are classified using one threshold, the work volume information may represent the area of ​​fields 500 with a progress rate greater than the threshold and the area of ​​fields 500 with a progress rate less than or equal to the threshold in different display formats. For example, the work volume information may be displayed in a format that allows for the identification of field 500 with a progress rate of 0%, field 500 with a progress rate greater than 0% but below a threshold, and field 500 with a progress rate greater than a threshold but less than 100%.

[0066] In this case, in step S120 shown in Figure 6, the work determination unit 150 of the work management device 100 determines the progress rate of the field 500 where the work device 30 performed work prior to the most recent period. For example, the work determination unit 150 determines the progress rate of the field 500 based on the work area 610 and the area of ​​the field 500 where the work device 30 performed work. For example, the work determination unit 150 determines the progress rate as the ratio of the area of ​​the work area 610 included in the field 500 to the area of ​​the field 500.

[0067] In this case, in step S230 shown in Figure 7, the output unit 180 of the work management device 100 determines work volume information that represents the progress rate of the fields 500 where the work device 30 performed work before the most recent period, using a display format that represents the area of ​​the fields 500. For example, the output unit 180 may determine work volume information that represents multiple groups of fields 500, classified based on the progress rate of the fields 500 and one or more thresholds, using an identifiable display format. Alternatively, in step S240 shown in Figure 7, the display unit 250 of the terminal 200 may determine the progress rate of the fields 500 where the work device 30 performed work before the most recent period, using a display format that represents the area of ​​the fields 500.

[0068] Furthermore, the work volume information displayed in the progress image 600 shown in Figure 2 may represent two or more of the following: the work area 610, past trajectory information, and the progress rate.

[0069] Furthermore, the display selection button 720 in the operation menu 700 shown in Figure 2 may be configured to select the type of work device 30 to display the most recent trajectory 620 and work amount information on the progress image 600, such as a tiller, planter, or harvester. For example, the operation menu 700 displays the most recent trajectory 620 and work amount information of the type of work device 30 selected by the display selection button 720. For example, when the slider of the display selection button 720 is slid to the left, the operation menu 700 is controlled so that the most recent trajectory 620 and work amount information of the type of work device 30 corresponding to that slider is not displayed. Also, when the slider of the display selection button 720 is slid to the right, the operation menu 700 is controlled so that the most recent trajectory 620 and work amount information of the type of work device 30 corresponding to that slider is displayed.

[0070] In this case, in step S120 shown in Figure 6 and step S230 shown in Figure 7, the work determination unit 150 of the work management device 100 determines the type of work device 30 used to perform the work. For example, the type of work device 30 is determined based on the model of the work device 30. Alternatively, the type of work device 30 may be entered by the user.

[0071] In this case, the display unit 250 receives selection information indicating the type of work device 30 that should represent either the most recent trajectory 620 or the workload information, or both, in the progress image 600. For example, if a user slides the slider of a display selection button 720 corresponding to one type to the right, the display unit 250 determines that it has received selection information indicating the type corresponding to the slid display selection button 720. Upon receiving the selection information, the display unit 250 outputs the selection information to the work management device 100. Upon receiving the selection information, the output unit 180 of the work management device 100 outputs information to the terminal 200 representing the most recent trajectory 620 for the type of work device 30 indicated in the selection information, and the workload information for the type of work device 30 indicated in the selection information. The display unit 250 of the terminal 200 displays the acquired information in the progress image 600.

[0072] Furthermore, the display unit 250 receives hidden information indicating the type of work device 30 that does not represent the most recent trajectory 620 and workload information in the progress image 600. For example, when a user slides the slider of a display selection button 720 corresponding to one type to the left, the display unit 250 determines that it has received hidden information indicating the type corresponding to the slid display selection button 720. Upon receiving hidden information, the display unit 250 displays the most recent trajectory 620 and workload information corresponding to the type of work device 30 indicated by the hidden information in the progress image 600 without showing them. This allows the user to check detailed progress information regarding work performed by a specific type of work device 30.

[0073] For example, in step S110 shown in Figure 6, the work determination unit 150 of the work management device 100 may determine the work period during which the work device 30 performed the work using any method. For example, the work determination unit 150 may determine the work period using status information of the work device 30. For example, the work determination unit 150 may determine the work period based on the status of various clutches of the work device 30.

[0074] Furthermore, in step S120 shown in Figure 6, the work determination unit 150 of the work management device 100 may determine the work area 610 in any way. For example, the work determination unit 150 may determine the work area 610 as the concave hull corresponding to the position represented in the position information of the work device 30.

[0075] Furthermore, in step S220 shown in Figure 7, the work field determination unit 170 of the work management device 100 may determine the work field in which the work device 30 performed work in the most recent period, based on the status information and position information of the work device 30. For example, the work field determination unit 170 may determine the work field based on the status of the various clutches of the work device 30. For example, the work field determination unit 170 may determine the work field as the field 500 that includes the position of the work device 30 when the status of the various clutches of the work device 30 indicates that work is being performed.

[0076] The embodiments and modifications described above are examples, and the configurations described in each embodiment and modification may be arbitrarily changed and / or combined as long as they do not impede the function. Furthermore, some of the functions described in the embodiments and modifications may be omitted if the necessary functions can be realized. For example, some or all of the processing of the work management device 100 may be performed by the terminal 200. Alternatively, some or all of the processing of the terminal 200 may be performed by the work management device 100. The work management program 420 may include a display program 430. Also, the work management system 1000 may not include the terminal 200 and may display image information on an external terminal not included in the work management system 1000.

[0077] Furthermore, the work management system 1000 may omit processing depending on the information represented in the progress image 600. For example, when the work management system 1000 represents the most recent trajectory 620 and work volume information for a specific type of work or a specific type of work device 30, it does not need to determine the type of work or the type of work device 30 of the work performed. In this case, the processing in step S130 shown in Figure 6 and the processing in step S230 shown in Figure 7 may be omitted. Also, when the work management system 1000 represents work volume information without distinguishing between fields 500 where work has been performed in the most recent period, the processing in step S220 shown in Figure 7 may be omitted.
