Description

[Technical field]

[0001] The present invention relates to a work display method, a work display system, and a work display program. [Background technology]

[0002] 2. Description of the Related Art In recent years, for the purpose of cultivation management, information on work carried out in a farm field has been provided to users, such as owners and workers of the farm field, using information and communication technology.

[0003] For example, Patent Document 1 discloses a technique for displaying information about agricultural work for each section set in a mesh-like pattern within a farm field. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7293070 Summary of the Invention [Problem to be solved by the invention]

[0005] For example, by displaying the speed of the working device for each section as information on agricultural work, it is possible to check sections where work is not being performed at an appropriate vehicle speed. For example, in the case of growing sugarcane by germinating the stalk after harvesting, if the speed at harvesting is too fast, the stalk itself may be pulled out. Also, if the speed at harvesting is too slow, work efficiency decreases. In this way, since there is an appropriate speed for each work, the skill of the worker can be improved by checking sections where work is not being performed at an appropriate vehicle speed. However, as a habit of the worker, the vehicle speed may not be appropriate at the start or end of work. Also, there are cases where multiple workers work on one field. For this reason, it is difficult to perform a more accurate work evaluation with only information on agricultural work in each section.

[0006] In view of the above circumstances, one object of the present disclosure is to support more accurate work evaluation by displaying information on a small area set in a farm field in a manner that allows comparison with the trajectory of a work implement. Other objects can be understood from the following description and the explanation of the embodiment. [Means for solving the problem]

[0007] The means for solving the problems will be described below using the numbers and symbols used in the description of the embodiment of the invention. These numbers and symbols are added in parentheses for reference purposes to show an example of the correspondence between the description of the claims and the description of the embodiment of the invention. Therefore, the description in parentheses should not be interpreted as limiting the scope of the claims.

[0008] To achieve the above object, an embodiment of a work display method includes determining map information representing a small area (510) set in a field (500) in a display format corresponding to operation information of a work implement (30) in the small area (510). The work display method also includes determining a trajectory (600) of the work implement (30) for at least a portion of a period corresponding to the operation information. The work display method further includes outputting display information representing an image in which the trajectory (600) of the work implement (30) is superimposed on the map information.

[0009] To achieve the above object, a work display system (1000) according to one embodiment includes a map information determination unit (160), a trajectory determination unit (170), and an output unit (180). The map information determination unit (160) determines map information representing a small area (510) set in a farm field (500) in a display format corresponding to operation information of a work implement (30) in the small area (510). The trajectory determination unit (170) determines a trajectory (600) of the work implement (30) for at least a portion of a period corresponding to the operation information. The output unit (180) outputs display information representing an image in which the trajectory (600) of the work implement (30) is superimposed on the map information.

[0010] To achieve the above object, an operation display program (410) according to one embodiment causes a calculation device (120, 220) to determine map information representing a small area (510) set in a field (500) in a display format corresponding to operation information of a work implement (30) in the small area (510). The operation display program (410) also causes the calculation device (120, 220) to determine a trajectory (600) of the work implement (30) for at least a portion of a period corresponding to the operation information. The work display program (410) also causes the calculation device (120, 220) to output display information representing an image in which the trajectory (600) of the work implement (30) is superimposed on the map information. Effect of the Invention

[0011] According to the above aspect, the user can confirm information that enables a more accurate evaluation of the work performed by the worker using the work device. [Brief description of the drawings]

[0013] (Embodiment 1) A work display 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 display system 1000 includes a work display device 100 and a terminal 200. The work display device 100 is communicatively connected to the work device 30 and the terminal 200 via a network 20, for example, the Internet.

[0014] The working device 30 performs work while moving in, for example, a farm field 500. The working device 30 includes, for example, a tractor, a combine harvester, a drone, and the like. The working device 30 includes a measuring device for measuring its own position, such as a GNSS (Global Navigation Satellite System) receiver, a quantum compass, and the like. The working device 30 measures its own position at each time, and outputs position information representing the measured position to the work display device 100 as operation information.

[0015] Furthermore, the working device 30 may acquire status information indicating the state of the working device 30 at each time, such as speed, steering angle, and ON / OFF status of various clutches, and output this to the work display device 100. When the working 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 the hitch height and lift arm angle indicating the attitude of the work machine. The status information is, for example, included in operation information and output from the working device 30 to the work display device 100.

[0016] 2, the work display device 100 determines map information representing operation information in a small area 510 set in a farm field 500 based on operation information acquired from the work device 30. For example, in the map information, the small area 510 is represented in a display format corresponding to the operation information, such as a color or a type of hatching.

[0017] The work display device 100 also determines a trajectory 600 of the work device 30 based on the position information included in the operation information of the work device 30. The work display device 100 outputs to the terminal 200 display information showing an image in which the determined trajectory 600 is superimposed on map information showing the operation information in the small region 510.

[0018] A user of terminal 200, for example, an owner of field 500 or a work manager, evaluates the work performed by the worker based on the display information displayed on terminal 200. Based on the evaluation of the work, the worker can improve his / her skills in working with the work device 30.

[0019] (Configuration of the work display system) The configuration of the work display device 100 included in the work display system 1000 shown in FIG. 1 will be described. As shown in FIG. 3, the work display device 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work display device 100 is a computer including, for example, 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 calculation device 120 executing the processing. The input / output device 110 includes various input devices and output devices, including, 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 connected to the network 20 and communicates with each device via the network 20. The communication device 130, for example, transfers operation information acquired from the maintenance device 30 to the arithmetic device 120. The communication device 130 also transfers a signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, for example, a network interface card (NIC) and a universal serial bus (USB).

[0021] The storage device 140 stores various data for determining display information related to the work device 30, such as operation data 400 and a work display program 410. The storage device 140 is used as a non-transitory tangible storage medium that stores the work display program 410. The work display program 410 may be provided as a computer program product recorded in a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

[0022] The operation data 400 stores operation information acquired from the maintenance device 30.

[0023] The arithmetic device 120 reads out the operation display program 410 from the storage device 140 and executes it to perform various data processing for determining display information related to the operation device 30. For example, the arithmetic device 120 includes a central processing unit (CPU) and the like.

[0024] The arithmetic device 120 reads and executes the work display program 410, and in cooperation with the storage device 140, realizes a data storage unit 150, a map information determination unit 160, a trajectory determination unit 170, and an output unit 180, as shown in FIG. 4. The data storage unit 150 stores operation data 400. The map information determination unit 160 determines map information representing operation information in each small area 510. The trajectory determination unit 170 determines a trajectory 600 of the work device 30 based on the operation information of the work device 30. The output unit 180 outputs display information representing an image in which the trajectory of the work device 30 is superimposed on the map information to the terminal 200.

[0025] Next, the configuration of the terminal 200 shown in Fig. 1 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.

[0026] The communication device 230 is connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers, for example, display information acquired from the work display device 100 to the arithmetic device 220. The communication device 230 includes various interfaces, such as a transceiver used for wireless communication in a wireless LAN (Local Area Network) or a cellular network, a NIC (Network Interface Card), a USB (Universal Serial Bus), and the like.

[0027] The storage device 240 stores various data for displaying display information acquired from the work display device 100, for example, a display program 420. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 420. The display program 420 may be provided as a computer program product recorded in a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

[0028] The arithmetic device 220 reads out and executes the display program 420 from the storage device 240, and performs various data processing to display the operation information in the small area 510 and the trajectory 600 of the working device 30. For example, the arithmetic device 220 includes a central processing unit (CPU) and the like.

[0029] 4, the arithmetic device 220 cooperates with the storage device 240 to implement the display unit 250 by reading and executing the display program 420. The display unit 250 cooperates with the input / output device 210 to display display information.

[0030] (Operation of the work display system) The operation of the work display system 1000 will be described. First, the process in which the work display device 100 acquires operation information from the work device 30 will be described. A worker moves to the field 500 with the work device 30, for example, a tractor, in order to perform work in the field 500. For example, the worker starts the drive device of the work device 30, for example, an engine or a motor. When the drive device is started, the work device 30 acquires operation information, specifically, position information and status information. The work device 30 outputs the acquired operation information to the work display device 100. For example, the work device 30 sequentially outputs operation information to the work display device 100. In addition, when the drive device is stopped, the work device 30 may output the operation information acquired from when the drive device is started to when it is stopped to the work display device 100.

[0031] When the arithmetic device 120 of the work display device 100 acquires operation information from the work device 30, it reads and executes the work display program 410. The data storage unit 150, which is realized by reading and executing the work display program 410, stores the operation information acquired from the work device 30 in the operation data 400.

[0032] In this way, the work display device 100 acquires operation information from the work device 30 and stores it in the operation data 400.

[0033] Next, a process in which the work display system 1000 displays the operation information in the small area 510 and the trajectory 600 of the work device 30 will be described. The arithmetic device 120 of the work display device 100 reads and executes the work display program 410 when a predetermined time, for example a preset time each day, is reached. The arithmetic device 120 may read and execute the work display program 410 when it receives a request signal for displaying display information from the terminal 200. When the arithmetic device 120 reads and executes the work display program 410, it starts the process shown in Fig. 6, which is part of the work display method.

[0034] In step S110, map information determination unit 160 realized by calculation device 120 determines map information representing the operation information of the maintenance device 30 in small area 510, based on the operation information of the maintenance device 30. For example, the map information represents small area 510 in a display format corresponding to the operation information of the maintenance device 30, as shown in FIG.

[0035] As shown in Fig. 2, the small regions 510 are set in the field 500 and have an area smaller than the field 500. For example, one small region 510 is formed in a rectangular shape, such as a square, and is provided so that the small regions 510 are in contact with each other. For example, the small regions 510 are arranged along latitude and longitude. The small regions 510 may be arranged so as to include an area other than the field 500 as shown in Fig. 2, or may be provided so as to divide the field 500 and fit within the field 500.

[0036] The display format of the small region 510 is determined according to the operation information of the working device 30 in the small region 510. For example, the map information determination unit 160 determines the zone in which the operation information of the working device 30 in the small region 510 is included, and displays the small region 510 in a display format according to the determined zone. For example, in the example of FIG. 2, the speed of the working device 30 is classified into five zones, and the small region 510 is displayed in a display format corresponding to the classified zone. For example, the map information determination unit 160 determines the small region 510 included in the first zone where the speed of the working device 30 is less than 1.5 km / h (1.5 kilometers per hour) and the small region 510 included in the second zone where the speed is 1.5 km / h or more and less than 3 km / h. In addition, the map information determination unit 160 determines the small region 510 included in the third zone where the speed is 3 km / h or more and less than 4.5 km / h, the small region 510 included in the fourth zone where the speed is 4.5 km / h or more and less than 6 km / h, and the small region 510 included in the fifth zone where the speed is 6 km / h or more. The map information determination unit 160 determines map information that represents the small areas 510 in different display formats depending on the corresponding zones. For example, the map information represents an image in which the target farm field 500 and the small areas 510 represented in different display formats depending on the zones of speed are superimposed on a map. In the example shown in FIG. 2, the first small area 510-1 represents that the working implement 30 is included in the first zone where the speed is less than 1.5 km / h, the second small area 510-2 represents that the working implement 30 is included in the second zone where the speed is 1.5 km / h or more and less than 3 km / h, and the third small area 510-3 represents that the working implement 30 is included in the third zone where the speed is 3 km / h or more and less than 4.5 km / h.

[0037] Here, the operation information in the small region 510 represents, for example, a statistical value of the operation information included in the small region 510, such as an average value, a median value, etc. The operation information represents the position of the working apparatus 30 at each time and the state of each working apparatus 30. For example, as shown in FIG. 7, the operation information represents the state of the working apparatus 30 at a positioning position 650 measured by the positioning device of the working apparatus 30. For example, a part of the operation information represents the state of the working apparatus 30 when the working apparatus 30 exists at the positioning position 650, such as the speed. For this reason, the map information determination unit 160 extracts operation information whose position represented in the position information is included in the small region 510, and determines the statistical value of the extracted operation information as the operation information in the small region 510. For example, in the example shown in FIG. 7, the first small region 510-1 includes a first positioned position 650-1, a second positioned position 650-2, a third positioned position 650-3, and a fourth positioned position 650-4. Therefore, the map information determination unit 160 determines statistics of the status information corresponding to the first positioned position 650-1, the status information corresponding to the second positioned position 650-2, the status information corresponding to the third positioned position 650-3, and the status information corresponding to the fourth positioned position 650-4. For example, the map information determination unit 160 determines the average value of the speed of the first positioned position 650-1, the speed of the second positioned position 650-2, the speed of the third positioned position 650-3, and the speed of the fourth positioned position 650-4 as the average speed in the small region 510.

[0038] In this way, the map information determination unit 160 determines map information that displays the small area 510 in a display format that corresponds to the operation information of the working device 30.

[0039] In step S120 shown in FIG. 6, the trajectory determination unit 170 determines the trajectory 600 of the working device 30 in at least a part of the period corresponding to the operation information of the working device 30. For example, as shown in FIG. 7, the trajectory determination unit 170 determines the trajectory 600 of the working device 30 in a period including a work period in which the operation information indicates that the working device 30 is performing work. For example, the trajectory determination unit 170 extracts operation information indicating a speed included in a predetermined range as the operation information when the working device 30 is performing work. The trajectory determination unit 170 determines the trajectory 600 of the working device 30 based on the extracted operation information. For example, the trajectory determination unit 170 determines the trajectory 600 of the working device 30 based on the position information included in the extracted operation information. For example, the trajectory determination unit 170 determines the trajectory 600 of the working device 30 as a line connecting the positioning positions 650 measured by the positioning device of the working device 30 in the order in which they were measured, for example, a line segment connecting two positioning positions 650 whose measured times are adjacent in a straight line as the trajectory 600 of the working device 30.

[0040] In step S130 shown in Fig. 6, the trajectory determination unit 170 determines the traveling direction of the working apparatus 30 based on the operation information of the working apparatus 30. For example, as shown in Fig. 7, the trajectory determination unit 170 determines a traveling direction 610 of the working apparatus 30 in a trajectory 600 of the working apparatus 30. For example, the trajectory determination unit 170 determines a direction from a positioned position 650 measured earlier to a positioned position 650 measured later as the traveling direction 610 of the working apparatus 30. Furthermore, when the traveling direction 610 is included in the status information of the working apparatus 30, the trajectory determination unit 170 may determine the traveling direction 610 of the working apparatus 30 based on the status information.

[0041] 6, the output unit 180 outputs to the terminal 200 display information showing an image in which the trajectory 600 of the working device 30 is superimposed on the map information. The display information may include direction information showing the traveling direction 610 of the working device 30. The display information shows, for example, an image showing a small area 510 displayed in a display format according to the operation information of the corresponding working device 30 on a map, and the trajectory 600 of the working device 30.

[0042] In step S150, the display unit 250 of the terminal 200 displays display information showing an image in which the trajectory 600 of the working device 30 is superimposed on the map information. For example, as shown in Fig. 2, the display unit 250 displays an image showing the map information and the trajectory 600 of the working device 30 on a map. For example, the image shown on the display unit 250 shows the traveling direction 610 of the working device 30 in an arbitrary manner. For example, the image shown on the display unit 250 shows the traveling direction 610 of the working device 30 by an arrow. The arrows showing the traveling direction 610 are arranged, for example, so as to extend along the trajectory 600 of the working device 30, and are shown at intervals of a predetermined distance along the trajectory 600.

[0043] A user, for example, a manager of the field 500, a work manager, a worker, etc., can check the operation information shown in the map information, such as the speed, and the process of the work performed in each small area 510 in relation to the entire work, by using the image displayed on the terminal 200.

[0044] For example, in the example shown in FIG. 2, the speed of the working implement 30 is relatively low in the first small area 510-1, the second small area 510-2, etc., where the work has started. In addition, in the third small area 510-3 and after, except for the fourth small area 510-4, etc., where the work is turned, the speed is kept at about 3km / h to 4.5km / h. However, the speed becomes relatively fast in the fifth small area 510-5 and after. In the sixth small area 510-6, before the work is completed, the speed is shown to exceed 6km / h. For example, by checking the image shown in FIG. 2, the user can evaluate that the speed of the working implement 30 tends to increase as the worker approaches the end of the work. In this way, the user can evaluate the work performed in the field 500 in more detail based on the display information displayed by the display unit 250.

[0045] (Embodiment 2) As shown in FIG. 8, the work display system 1000 may display weather information when work is performed in the field 500, for example, information about rain. Appropriate work in the field 500, for example, an appropriate speed of the work implement 30, varies depending on weather conditions. For this reason, the work display system 1000 provides the user with weather information for the field 500, allowing the user to more accurately evaluate the work. The work display system 1000 may also display weather information from the day the work is performed until a predetermined period ago. The condition of the ground of the field 500 when the work is performed, for example, softness, may change depending on weather conditions from the day the work is performed until a predetermined period ago, for example, the amount of precipitation. The user can more accurately evaluate the work by checking the weather information for the period from the day the work is performed until the predetermined period ago.

[0046] For example, the weather information is acquired from a weather information distribution device 40 outside the work display system 1000, as shown in FIG.

[0047] (Configuration of the work display system) 10, the work display system 1000 in this embodiment is similar to that in embodiment 1, except for an output unit 180B realized in the work display system 1000, and therefore detailed description thereof will be omitted, except for the output unit 180B. As in embodiment 1, the output unit 180B outputs display information presenting an image in which the trajectory 600 of the work implement 30 is superimposed on map information to the terminal 200. In addition, the output unit 180B acquires weather information for the field 500 from the weather information distribution device 40.

[0048] (Operation of the work display system) A description will be given of the operation of the work display system 1000. The process in which the work display device 100 acquires operation information from the work device 30 is similar to that in the first embodiment, and therefore a detailed description will be omitted.

[0049] The process by which the work display system 1000 displays the operation information in the small area 510 and the trajectory 600 of the work device 30 will be described. As in the first embodiment, the calculation device 120 of the work display device 100 reads and executes the work display program 410 when a predetermined time, for example a preset time each day, is reached. When the calculation device 120 reads and executes the work display program 410, it starts the process shown in Fig. 11, which is part of the work display method.

[0050] The processes from step S110 to step S130 are similar to those in the first embodiment, and therefore a detailed description thereof will be omitted.

[0051] In step S135, output unit 180B acquires weather information for the field 500 from the weather information distribution device 40. For example, output unit 180B determines the area of ​​field 500 and the period, for example, the date, during which the work was performed, based on the position information of the work device 30 that performed work in the field 500. Output unit 180B acquires weather information, for example, the amount of precipitation, for the determined area for a predetermined period prior to the period during which the work was performed, for example, up to four days prior, from the weather information distribution device 40.

[0052] In step S140B, output unit 180B outputs to terminal 200 display information showing an image in which trajectory 600 of working implement 30 is superimposed on map information, as in the first embodiment. Furthermore, output unit 180B includes, in the display information to be output, weather information for a period from the period in which the work was performed until a predetermined period prior. The weather information included in the display information indicates, for example, the total amount of precipitation that fell on each day from the period in which the work was performed in field 500 until the predetermined period prior.

[0053] In step S150B, display unit 250 of terminal 200 displays display information representing an image in which trajectory 600 of working implement 30 is superimposed on map information, as in the first embodiment. Since the display information includes meteorological information for field 500, display unit 250 also displays meteorological information for field 500, as shown in FIG.

[0054] By checking the weather information as well, the user can evaluate the work carried out in the field 500 while taking into account the weather conditions.

[0055] (Modification) 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 functions are not impaired. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the necessary functions can be realized.

[0056] 12, the trajectory 600 of the working device 30 may be displayed in different display formats as divided trajectories 601 divided according to the time when the working device 30 performed work. For example, the display information output from the output unit 180 of the work display device 100 displays a first divided trajectory 601-1 traveled while performing work on September 14th and a second divided trajectory 601-2 traveled while performing work on September 15th in different display formats. The display information may also include work period information 602 indicating a period, for example a date, corresponding to each divided trajectory 601.

[0057] In this case, in step S120 shown in FIG. 6 or FIG. 11, the orbit determination unit 170 determines the divided orbits 601 by dividing the orbit 600 of the working device 30 into one or more parts based on the time indicated in the position information. For example, the orbit determination unit 170 determines the divided orbits 601 based on the time when the working device 30 was on the orbit 600. For example, the orbit determination unit 170 determines a period including the time when the operation information was measured from a predetermined period group, and determines the orbit 600 of the working device 30 in the determined period as the divided orbits 601. The orbit determination unit 170 divides the orbit 600 into period groups of one day, for example. Specifically, the orbit determination unit 170 may determine the divided orbits 601 divided according to the date when the operation information was measured. The orbit determination unit 170 may also divide the orbit 600 into period groups of half-days. Specifically, the orbit determination unit 170 may determine the divided orbits 601 divided according to the morning and afternoon of each day.

[0058] In step S110 shown in FIG. 6 or FIG. 11, the map information determination unit 160 may classify the operation information in the small region 510 into any zone. For example, the number of zones may be more or less than five. Furthermore, the range of each zone may be set arbitrarily, and the widths of the multiple zones (representing 1.5 km / h in the example shown in FIG. 2) may be the same or different.

[0059] Further, the operation information in the small region 510 is not limited to the above example, and may represent any information that can be obtained from the operation information. For example, the speed of the operation device 30 may be determined based on the position information of the operation device 30. In this case, the map information determination unit 160 may determine the speed of the operation device 30 by dividing the distance between two positioning positions 650 at which the measured times are adjacent by the interval between the measured times. Furthermore, the map information determination unit 160 may use any information related to the work as the operation information represented in the display format of the small region 510. For example, the map information determination unit 160 may use the load of the drive device or the amount of material, such as fertilizer or pesticide, sprayed as the operation information represented in the display format of the small region 510.

[0060] For example, the small regions 510 may be set in an area including the field 500 in any configuration. For example, the small regions 510 are not limited to a rectangle, and may have any shape, such as a hexagon. Furthermore, the small regions 510 may be formed in the same shape as the other small regions 510, or may be formed in a different shape. Furthermore, the small regions 510 may be inclined with respect to the field 500 as shown in FIG. 13. Furthermore, the small regions 510 may be arranged in any direction, not aligned in the latitude and longitude directions. For example, the small regions 510 may be provided so as to include an area where work has been performed by the working device 30. For example, the small regions 510 may be arranged in an area smaller than the field 500. For example, the area occupied by all the arranged small regions 510 may be provided so as to include an area where work has been performed by the working device 30, and may not include the entire field 500.

[0061] 6 or 11, the trajectory determination unit 170 may determine the trajectory 600 for any period including a period during which the work is being performed by the work device 30, out of the period corresponding to the operation information of the work device 30. For example, the trajectory determination unit 170 may determine the trajectory 600 for all periods corresponding to the operation information of the work device 30 as the trajectory 600 to be displayed in the display information. The trajectory determination unit 170 may also extract a period during which the work device 30 is present in the field 500 as a period during which work is being performed, and determine the trajectory 600 for the extracted period as the trajectory 600 to be displayed in the display information.

[0062] Furthermore, the trajectory determination unit 170 may determine the trajectory 600 of the working device 30 excluding a period during which the working device 30 is not actually performing work, such as a turning movement of the working device 30. For example, when the traveling direction of the working device 30 changes by a preset threshold value or more within a specified period, the trajectory determination unit 170 may determine the trajectory 600 of the working device 30 excluding that period, assuming that the working device 30 is performing a turning movement. Also, when the working device 30 tows a working machine such as a rotary, the working machine is raised and turned, so the trajectory determination unit 170 may determine the trajectory 600 of the working device 30 excluding a period during which the operation information of the working device 30 indicates that the working machine is raised.

[0063] The traveling direction 610 of the working device 30 may be omitted from the image shown in the display information of Fig. 2. In this case, step S130 shown in Fig. 6 or Fig. 11 may be omitted.

[0064] In step S135 shown in Fig. 11, the output unit 180B may obtain, from the weather information distribution device 40, information indicating the presence or absence of precipitation, for example, information indicating whether it is rain or other, as information regarding rain in the field 500. In this case, the display information may not indicate the amount of precipitation, but may indicate the presence or absence of precipitation, for example, information indicating whether it is rain or other. The display information may also indicate both the amount of precipitation and the presence or absence of precipitation. The output unit 180B may also obtain, from the weather information distribution device 40, information regarding the amount of clouds in the field 500, for example, information such as clear, sunny, or cloudy, and display this in the display information.

[0065] For example, a part or all of the processing of the work display device 100 may be executed by the terminal 200. Also, a part or all of the processing of the terminal 200 may be executed by the work display device 100. The work display program 410 may include a display program 420. The work display system 1000 does not include the terminal 200, and may cause an external terminal not included in the work display system 1000 to display the display information.
