Description

[Technical Field]

[0001] The present invention relates to a farm field registration method, a farm field registration system, and a farm field registration program. [Background technology]

[0002] Patent Document 1 (JP 2024-22037 A) discloses a work management method for identifying and managing a work area where a work device has performed work, based on positioning information indicating multiple positions of the work device that moves within a farm field while performing work. In this work management method, when a period in which the work device performed work straddles a reference time and is included in a first management unit period and a second management unit period, a combined work area that combines the first work area where the work device performed work in the first management unit period and the second work area where the work device performed work in the second management unit period is managed in association with the first management unit period.

[0003] In this way, with the above-mentioned work management method, when work is performed continuously on one work area across a reference time used for managing the work area, the work area can be managed as a single area without being divided by the reference time. On the other hand, with the above-mentioned work management method, when work on one work area is performed over multiple discontinuous periods, the work area cannot be managed as a single area.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a farm field registration method, a farm field registration system, and a farm field registration program according to the present disclosure will be described below with reference to the accompanying drawings.

[0013] (Embodiment) 1 , a farm field registration system 1 according to one embodiment includes a farm field registration device 4 and a user terminal 5. The farm field registration system 1 may further include an on-board terminal 20. The farm field registration device 4, the user terminal 5, and the on-board terminal 20 may communicate with each other via a network 3 by wired communication and / or wireless communication.

[0014] The on-board terminal 20 is mounted on a work device 2. The work device 2 moves on the ground and performs agricultural work such as tilling and harvesting on a field 9 and crops grown in the field 9. As an example, the work device 2 may be a work device 2 such as a tiller that performs tilling, a transplanter or rice transplanter that performs transplanting work, or a combine that performs harvesting work, or it may be a tractor that pulls work machines that perform harvesting, tilling, fertilizing, etc.

[0015] The on-board terminal 20 generates position information that measures the position of each of a plurality of points that the working device 2 passes through while working in the field. Position measurement may be performed using a Global Navigation Satellite System (GNSS) or a quantum compass that does not require an external auxiliary system such as an artificial satellite. The points where the position is measured are called positioning points. The position information includes positioning time information that indicates the positioning time when the position was measured at each positioning point. The on-board terminal 20 transmits the position information to the field registration device 4.

[0016] The field registration device 4 estimates the work area in which the work device 2 performed work, based on the location information received from the onboard terminal 20. The field registration device 4 further registers multiple work areas selected by the user from the estimated work areas as a single field 9 for collective management. This allows for easy management of multiple work areas. As an example, even if it is desired to perform the same work on multiple work areas at the same time, and strictly speaking, the work on each work area is performed across multiple days or across multiple discontinuous periods, by managing the multiple work areas as work areas belonging to the same field 9, it is possible to easily distinguish one work area from another field 9 to which the other work areas belong, making it easier to plan work on a field-by-field basis.

[0017] It should be noted that the field 9 to be registered in this embodiment is a unit of land used for managing the above-mentioned work plans, etc., and may have a different meaning from a field as a range of land registered with an administrative agency or a field as a range of land defined by physical boundaries.

[0018] The user terminal 5 may include a smartphone, tablet terminal, personal computer, etc. that have communication functions, display functions, and input functions. The user terminal 5 acquires work area information that represents the work area from the field registration device 4, displays the position and range of the work area so that the user can visually confirm it, accepts an operation by the user to set an area calculated based on a collection of some of the work areas as a registered field, and transmits registered field information that represents the registered field to the field registration device 4.

[0019] As shown in Fig. 2, the farm field registration device 4 according to one embodiment may be configured as a so-called computer. In the example of Fig. 2, the farm field registration device 4 includes a bus 41, a calculation device 42, a storage device 43, a communication device 44, and an input / output device 45. The bus 41 may be configured to realize communication between the calculation device 42, the storage device 43, the communication device 44, and the input / output device 45.

[0020] The arithmetic device 42 executes at least a part of the field registration program according to one embodiment, thereby realizing the processing of a position information acquisition unit 421, a work area information generation unit 422, a work area information transmission unit 423, and a field registration unit 424. The position information acquisition unit 421, the work area information generation unit 422, the work area information transmission unit 423, and the field registration unit 424 are virtual functional blocks that execute processing realized by the arithmetic device 42 and the storage device 43 working together. The position information acquisition unit 421 acquires, from the on-board terminal 20, position information generated when the work device 2 performs work in the field 9. The work area information generation unit 422 calculates the position and range of the work area in which the work device 2 performed work based on the position information, generates work area information, and stores the generated work area information in the work area information storage unit 432. The work area information transmission unit 423 transmits the work area information to the user terminal 5. The field registration unit 424 registers the field 9 in the registered field information storage unit 433 based on the registered field information received from the user terminal 5.

[0021] The storage device 43 includes a program storage unit 431, a work area information storage unit 432, and a registered field information storage unit 433. At least a part of the field registration program may be read from an external recording medium 430 and stored in the program storage unit 431. The recording medium 430 may be a non-transitory and tangible medium. The work area information storage unit 432 may store location information acquired from the on-board terminal 20 and work area information generated by the work area information generation unit 422. The registered field information storage unit 433 may store registered field information representing the field 9 registered by the field registration unit 424.

[0022] The communication device 44 communicates with external devices including the on-board terminal 20 and / or the user terminal 5 by wireless communication and / or wired communication via the network 3. The farm field registration program may be received by the communication device 44 from the outside and stored in the program storage unit 431.

[0023] The input / output device 45 outputs information to the user and accepts operations input by the user. As an example, the input / output device 45 includes a display device that outputs images, and a keyboard and / or a mouse that accepts input.

[0024] 3, the user terminal 5 may be configured as a computer including a bus 51, a computing device 52, a storage device 53, a communication device 54, and an input / output device 55, similar to the farm field registration device 4. In the example of FIG. 3, the bus 51 may be configured to realize communication between the computing device 52, the storage device 53, the communication device 54, and the input / output device 55.

[0025] The arithmetic unit 52 executes at least a portion of the field registration program according to one embodiment, thereby implementing the processes of a work area information acquisition unit 521, extraction condition setting unit 522, work area extraction unit 523, extracted work area display unit 524, work area selection unit 525, registration candidate field calculation unit 526, registered field setting unit 527, and registered field information transmission unit 528. The work area information acquisition unit 521 acquires work area information from the work area information transmission unit 423 of the field registration device 4 shown in FIG. 2. The extraction condition setting unit 522 in FIG. 3 sets extraction conditions for extracting a portion of the work area represented by the acquired work area information. The work area extraction unit 523 extracts the portion of the work area based on the set extraction conditions and sets it as an extracted work area. The extracted work area display unit 524 displays the position and range of the extracted work area information representing the extracted work area so that the user can visually confirm it. The work area selection unit 525 accepts an operation by the user to select at least a portion of the extracted work areas to be included in the registered field as the selected work area. The registration candidate field calculation unit 526 calculates the position and range of the registration candidate field that is a candidate for the registered field based on the position and range of the selected work area. The registration field setting unit 527 accepts an operation by the user to correct the position and range of the registration candidate field as necessary and set the position and range of the registered field. The registered field information transmission unit 528 transmits registered field information representing the registered field to the field registration unit 424 of the field registration device 4 in Figure 2.

[0026] The storage device 53 includes a program storage unit 531 and a data storage unit 532. At least a part of the farm field registration program may be read from an external recording medium 530 and stored in the program storage unit 531. The recording medium 530 may be a non-transitory and tangible medium. The data storage unit 532 may store work area information acquired from the work area information transmission unit 423 of the farm field registration device 4 shown in FIG. 2.

[0027] 3 communicates with external devices including the farm field registration device 4 by wireless communication and / or wired communication via the network 3. The farm field registration program may be received by the communication device 44 from the outside and stored in the program storage unit 431.

[0028] The input / output device 55 outputs information to the user and accepts operations input by the user. As an example, the input / output device 55 includes a touch panel that integrates a display device that outputs images and a touchpad that accepts input by touch operation.

[0029] An example of the processing of the field registration method according to one embodiment will be described with reference to the sequence diagram of Fig. 4. The field registration method may be started when the field registration device 4 and the user terminal 5 are started. At this time, the arithmetic device 42 of the field registration device 4 shown in Fig. 2 and the arithmetic device 52 of the user terminal 5 shown in Fig. 3 each execute at least a part of a field registration program, thereby realizing the processing of the field registration method in the sequence diagram shown in Fig. 4.

[0030] When the arithmetic device 42 of the field registration device 4 of FIG. 2 starts processing of the field registration method, step S401 of FIG. 4 is executed. In step S401, the position information acquisition unit 421 of FIG. 2 acquires the position information of the operation device 2 transmitted by the onboard terminal 20 of FIG. 1. Here, if the onboard terminal 20 is included in the field registration system 1 according to this embodiment, the process in step S201 of the sequence diagram shown in FIG. 4 in which the onboard terminal 20 transmits the position information to the field registration device 4 is included in the field registration method according to this embodiment. The position information includes information indicating the positions of the positioning points and information indicating the positioning times when the positions of each positioning point were measured. In step S201, the onboard terminal 20 may transmit to the field registration device 4, in addition to the position information, operation device identification information that identifies the operation device 2, worker identification information that identifies the worker who operated the operation device 2 to perform the work, operation information that indicates the status of the operation device 2 during the work, and the like. The position information acquisition unit 421 in FIG. 2 may store various pieces of information, including the position information of the working device 2 , received and acquired from the on-board terminal 20 in the working area information storage unit 432 .

[0031] After step S401 in FIG. 4, step S402 is executed. In step S402, the work area information generation unit 422 in FIG. 2 generates work area information based on the position information. The work area information represents the position and range of the work area in which the work apparatus 2 has performed work. As an example, the work area information generation unit 422 may calculate or estimate the position and range of the work area by performing image processing such as convex hull processing or concave hull processing on multiple positioning points included in the position information. In addition to the position and range of the work area, the work area information generation unit 422 may calculate or estimate the time when the work apparatus 2 performed the work and the type of work performed by the work apparatus 2 based on the position information. The work area information generation unit 422 may store work area information representing various information including the position and range of the work area in the work area information storage unit 432.

[0032] Step S501 is executed after step S402 in Fig. 4. In step S501, the work area information acquisition unit 521 of the user terminal 5 shown in Fig. 3 requests work area information from the farm field registration device 4. More specifically, the work area information acquisition unit 521 generates a request signal requesting the work area information stored in the work area information storage unit 432 of the farm field registration device 4 shown in Fig. 2, and transmits the request signal to the farm field registration device 4.

[0033] Step S403 is executed after step S501 in Fig. 4. In step S403, the work area information transmission unit 423 of the farm field registration device 4 shown in Fig. 2 transmits work area information to the user terminal 5. More specifically, in response to a request signal received from the user terminal 5, the work area information transmission unit 423 reads out the work area information from the work area information storage unit 432 and transmits it to the user terminal 5.

[0034] After step S403 in Fig. 4, step S502 is executed. In step S502, the work area information acquisition unit 521 of the user terminal 5 shown in Fig. 3 acquires the work area information. More specifically, the work area information acquisition unit 521 receives and acquires the work area information transmitted from the work area information transmission unit 423 of the farm field registration device 4 shown in Fig. 2. The work area information acquisition unit 521 in Fig. 3 may store the acquired work area information in the data storage unit 532.

[0035] After step S502 in Fig. 4, step S503 is executed. In step S503, the extraction condition setting unit 522 of the user terminal 5 shown in Fig. 3 sets extraction conditions for extracting a portion of the work area represented by the work area information. More specifically, the extraction condition setting unit 522 accepts an operation by the user of the user terminal 5 to set extraction conditions for extracting a work area to be managed as a single field from among the multiple work areas represented by the work area information. As an example, the operation by the user may be performed using a touch panel serving as the input / output device 55 of the user terminal 5.

[0036] After step S503 in FIG. 4, step S504 is executed. In step S504, the work area extraction unit 523 of the user terminal 5 shown in FIG. 3 extracts a work area that satisfies the set extraction conditions. More specifically, the work area extracted based on the set extraction conditions is extracted from among the multiple work areas represented by the work area information stored in the data storage unit 532. Hereinafter, for the sake of distinction, the work area extracted in step S504 will be referred to as the extracted work area. The work area extraction unit 523 in FIG. 3 stores the extracted extracted work area in the data storage unit 532. As an example, the work area extraction unit 523 may perform a process of adding additional data to the work area information stored in the data storage unit 532, such as setting a flag indicating that the work area is an extracted work area in the part of the work area represented by the work area information.

[0037] After step S504 in FIG. 4, step S505 is executed. In step S505, the extraction work area display unit 524 of the user terminal 5 shown in FIG. 3 displays the extraction work area. More specifically, the extraction work area display unit 524 displays information representing the extraction work area on a touch panel serving as the input / output device 55 so that the user of the user terminal 5 can visually confirm the information. As an example, the extraction work area display unit 524 may display the position and range of the extraction work area superimposed on a map as information representing the extraction work area, or may display identification information for identifying the extraction work area as a character string. The identification information of the extraction work area may include work time information representing the time when work was performed in the extraction work area and work type information representing the type of work performed in the extraction work area.

[0038] After step S505 in Fig. 4, step S506 is executed. In step S506, the work area selection unit 525 of the user terminal 5 shown in Fig. 3 sets a selected work area by selecting at least a part of the extraction work area. More specifically, the work area selection unit 525 accepts an operation by the user of the user terminal 5 to select and set at least a part of the extraction work area as a work area to be registered in the field. As an example, the operation by the user may be performed on a touch panel serving as the input / output device 55 of the user terminal 5.

[0039] After step S506 in Fig. 4, step S507 is executed. In step S507, the registration candidate field calculation unit 526 of the user terminal 5 shown in Fig. 3 combines the selected work areas into one area to calculate the registration candidate field. Here, the registration candidate field is a candidate for an area to be registered as a field. More specifically, the registration candidate field calculation unit 526 calculates the position and extent of the registration candidate field by performing image processing such as convex hull processing and concave hull processing on the set of selected work areas. The registration candidate field is treated as a candidate for registration field in the sense that its position and extent may be modified before it is actually registered as a field.

[0040] After step S507 in FIG. 4, step S508 is executed. In step S508, the registration field setting unit 527 of the user terminal 5 shown in FIG. 3 sets a registration field based on the registration candidate field. More specifically, the registration field setting unit 527 accepts an operation by the user of the user terminal 5 to set the position and range of the registration field based on the position and range of the registration candidate field. As an example, the registration field setting unit 527 may display the position and range of the registration candidate field superimposed on a map on a touch panel serving as the input / output device 55 of the user terminal 5, and accept an operation by the user to modify the displayed position and range of the registration candidate field. Furthermore, the registration field setting unit 527 may accept an operation by the user to set the modified position and range of the registration candidate field as the position and range of the registration field, and store information representing the set position and range of the registered field in the data storage unit 532.

[0041] After step S508 in Fig. 4, step S509 is executed. In step S509, the registered field information transmitting unit 528 of the user terminal 5 shown in Fig. 3 transmits the registered field information to the field registration device 4. Here, the registered field information represents the registered field set in step S508 in Fig. 4. More specifically, the registered field information transmitting unit 528 generates the registered field information and transmits it to the field registration device 4. As an example, the registered field information may include identification information that identifies the registered field, information that represents the location and range of the registered field, and identification information of the work area that belongs to the registered field.

[0042] After step S509 in Fig. 4, step S404 is executed. In step S404, the field registration unit 424 of the field registration device 4 shown in Fig. 2 registers the registered field. More specifically, the field registration unit 424 receives the registered field information transmitted by the user terminal 5 in step S509 in Fig. 4, and registers the registered field represented by the received registered field information in the registered field information storage unit 433 shown in Fig. 2. At this time, the field registration unit 424 may store, in the work area information storage unit 432, field location affiliation information indicating that each of the work areas belonging to the registered field belongs to the registered field.

[0043] After step S404 in Fig. 4, the processing by the field registration device 4 in the processing of the field registration method according to this embodiment ends. Similarly, after step S509 in Fig. 4, the processing by the user terminal 5 in the processing of the field registration method according to this embodiment ends. Furthermore, if the onboard terminal 20 is included in the field registration system 1 according to this embodiment, after step S201 in Fig. 4, the processing by the onboard terminal 20 in the processing of the field registration method according to this embodiment ends.

[0044] Details of steps S503, S504, and S505 in Fig. 4 will be described with reference to Fig. 5. Fig. 5 shows an example of the display of touch panel 551 serving as input / output device 55 of user terminal 5 shown in Fig. 3 in steps S503, S504, and S505. In the example of Fig. 5, touch panel 551 displays extraction condition setting window 611 for accepting the operation of setting extraction conditions in step S503 of Fig. 4, and extraction work area 81 extracted in step S504 of Fig. 4 based on the extraction conditions set in step S503 of Fig. 4.

[0045] In step S503 of FIG. 4 , the extraction condition setting unit 522 of FIG. 3 displays an extraction condition setting window 611 on the touch panel 551, prompting the user of the user terminal 5 to input extraction conditions. When the user operates the extraction condition setting window 611 to set extraction conditions, the extraction condition setting unit 522 of FIG. 3 accepts the operation. In the example of FIG. 5 , the extraction condition setting window 611 has boxes for inputting the start date and time of the work period, the end date and time of the work period, the type of work, the work device identification information, the worker identification information, and whether or not the work belongs to a field. However, the extraction conditions shown in FIG. 5 are merely an example and do not limit the present embodiment. In the example of FIG. 5 , extraction conditions are set for the start date and time of the work period, the end date and time of the work period, the type of work, and the type of field, but not for the work device identification information and the worker identification information. In this way, the user may set only some or all of the settable extraction conditions. In addition, if the extraction condition for a work area is set to the sole requirement that the area does not belong to any field, it is possible to extract all work areas that are not yet included in any registered field.Furthermore, if the type or variety of crops to be grown is set as an extraction condition for a work area, it is possible to extract work areas that cultivate the specified crops.

[0046] The touch panel 551 may further be provided with a button 612 for resetting the extraction conditions set in the extraction condition setting window 611, and a button 613 for proceeding to the process of extracting a work area that satisfies the extraction conditions set in the extraction condition setting window 611.

[0047] When the user operates button 613, in step S504 of Fig. 4, the work area extraction unit 523 of Fig. 3 extracts, from the work areas represented by the work area information, a work area that satisfies the extraction conditions as an extracted work area. Then, in step S505 of Fig. 4, the extracted work area display unit 524 of Fig. 3 displays the extracted work area 81 on the touch panel 551, superimposed on a map of the area in which the extracted work area 81 is located. In the example of Fig. 5, the extracted work area 81 that satisfies the extraction conditions is displayed with solid lines and hatching.

[0048] Details of step S506 in Fig. 4 will be described with reference to Fig. 6. Fig. 6 shows an example of the display of touch panel 551 serving as input / output device 55 of user terminal 5 shown in Fig. 3 in step S506. In the example of Fig. 6, touch panel 551 displays a work area selection window 621 for accepting an operation to select work areas to be included in the field 9 to be registered from among the extraction work areas in step S506 in Fig. 4, the selected selected work area 82, and other unselected extraction work areas 83.

[0049] In step S506 of FIG. 4, the work area selection unit 525 of FIG. 3 displays a work area selection window 621 on the touch panel 551, prompting the user of the user terminal 5 to select from the extracted work areas those work areas to be included in the field 9 to be registered. In the example of FIG. 6, the work area selection window 621 displays character strings representing the extracted work areas and buttons for setting whether to select each extracted work area. Note that in the example of FIG. 6, the character strings representing the extracted work areas include the date and time the work was performed and the type of work. Also, in the example of FIG. 6, a button indicating that the corresponding extracted work area is selected is represented by a black circle, and a button indicating that the corresponding extracted work area is not selected is represented by a white circle. The user may switch between the selected and unselected states of the corresponding extracted work area by operating a button displayed as a black or white circle.

[0050] Each time the user operates the work area selection window 621 to switch between the selected and unselected states of an extraction work area, the display of the work area superimposed on the map displayed on the touch panel 551 may switch between the selected selected work area 82 and other unselected extraction work areas 83. In the example of FIG. 6, of the six extraction work areas displayed in the work area selection window 621, the fourth extraction work area from the top is unselected, and the remaining five extraction work areas are selected. Corresponding to this state, of the extraction work areas displayed superimposed on the map, the unselected extraction work area 83 is displayed with a dashed line for distinction, and the remaining five selected extraction work areas, i.e., the selected work area 82, are displayed with solid lines and hatching.

[0051] The touch panel 551 may further be provided with a button 622 for returning to the process of setting extraction conditions, a button 623 for proceeding to the process of calculating the field, etc. When the user of the user terminal 5 operates button 622, the process of the user terminal 5 may return to step S503 in Fig. 4. At this time, the display on the touch panel 551 may return to the state of the extraction condition setting mode shown in the example of Fig. 5. Furthermore, when the user operates button 623, the process of the user terminal 5 proceeds to step S507 in Fig. 4.

[0052] Details of step S507 in Fig. 4 will be described with reference to Fig. 7. Fig. 7 shows an example of the display of touch panel 551 serving as input / output device 55 of user terminal 5 shown in Fig. 3 in step S507. In the example of Fig. 7, touch panel 551 displays registration candidate field 84 calculated in step S507 in Fig. 4. Touch panel 551 may further display a registration field information setting window 631 and buttons 632 and 633. Details of registration field information setting window 631 and buttons 632 and 633 will be described later.

[0053] In step S507 in Fig. 4, the registration candidate field calculation unit 526 in Fig. 4 calculates the position and area of ​​the registration candidate field 84 by image processing such as convex hull processing and concave hull processing of the selected work area 82, and displays the calculated registration candidate field 84 superimposed on a map including the selected work area 82. In the example in Fig. 7, the registration candidate field 84 has been calculated by convex hull processing of the selected work area 82, and has the shape of a polygon surrounded by a total of five points, i.e., a pentagon.

[0054] Details of step S508 in Fig. 4 will be described with reference to Fig. 8. Fig. 8 shows an example of the display of the touch panel 551 serving as the input / output device 55 of the user terminal 5 shown in Fig. 3 in step S508. In the example of Fig. 8, the touch panel 551 displays a registered field 85 that the user sets by modifying the position and range of the registration candidate field 84 as necessary in step S508 in Fig. 4, and a registered field information setting window 631 in which various information to be registered in association with the registered field 85 is set.

[0055] In step S508 of Fig. 4, the registered field setting unit 527 of the user terminal 5 shown in Fig. 3 accepts an operation by the user to modify the position and / or range of the registration candidate field 84, and displays the registered field 85 resulting from the modification on the touch panel 551, superimposed on the map. More specifically, the user may set the position and range of the registered field 85 by performing operations such as modifying the positions of multiple points 71 included in the polygon corresponding to the shape of the registration candidate field 84, deleting those points 71, or adding new points 71.

[0056] In the examples of Figures 7 and 8, the user corrects the position of point 71 shown in Figure 7 to the position of point 71 shown in Figure 8, thereby approximating the shape of the registration candidate field 84 to the rectangular shape of the actual field 9 and setting this as the shape of the registered field 85. Here, even if the unselected extraction work area 83 were included in the selected work area 82, the position and extent of the registered field 85 would likely be the same as in the example of Figure 8. In other words, the position and extent of the collection of extraction work areas 81 belonging to the registered field 85 registered in this embodiment do not necessarily coincide with the position and extent of the registered field 85. The user can either make the position and extent of the registered field 85 coincide with or not coincide with the registered field, or with or not coincide with the position and extent of the field defined by physical boundaries.

[0057] The user may further perform an operation to set various pieces of information to be registered in association with the registered field 85 in the registered field information setting window 631. The registered field setting unit 527 in FIG. 3 accepts the operation and displays the registered field information setting window 631 reflecting the result on the touch panel 551. In the example of FIGS. 7 and 8, the information about the registered field 85 includes a field ID, a field name, a calendar name, a project name, a cropping type, progress, notes, and the work area to which the field belongs. As an example, the field ID is information for identifying the registered field 85. The field name is the name of the registered field 85. The calendar name represents a cultivation plan for a crop to be cultivated in a work area to which the registered field 85 belongs. The project name represents a project for cultivating a crop in a work area to which the registered field 85 belongs. The cropping type indicates the method for growing crops in a work area belonging to the registered field 85. The progress indicates the progress of cultivation in a work area belonging to the registered field 85. The memo is an item in which the user can freely write about the registered field 85. The item for the working area to which it belongs is a character string that identifies the working area belonging to the registered field 85.

[0058] The touch panel 551 may further be provided with a button 632 for returning to the process of selecting the selection work area 82, a button 633 for proceeding to the process of registering the field, etc. When the user operates button 632, the process of the user terminal 5 may return to step S506 in Fig. 4. When the user operates button 633, the process of the user terminal 5 proceeds to step S509 in Fig. 4.

[0059] When the processing of the user terminal 5 proceeds to step S509 in Fig. 4, the registered field information transmission unit 528 of the user terminal 5 shown in Fig. 3 transmits information indicating the position and range of the registered field 85 and various information about the registered field 85 reflected in the registered field information setting window 631 to the field registration device 4. Then, step S404 in Fig. 4 is executed to register the registered field 85, and the processing of the field registration method according to this embodiment ends.

[0060] As described above, the farm field registration method, farm field registration system 1, and farm field registration program according to one embodiment make it possible to manage a work area in which work has been carried out over multiple discontinuous periods as a single area.

[0061] (Variation) In the embodiment described above, as shown in FIG. 4, the user terminal 5 sets extraction conditions, extracts work areas, selects work areas, calculates candidate fields for registration, and sets registered fields. As a variation of this configuration, a configuration in which these processes are performed by the field registration device 4 will be described. In this variation, the field registration device 4 of FIG. 2 includes an extraction condition setting unit 522, a work area extraction unit 523, a work area selection unit 525, a candidate field calculation unit 526 for registration, and a registered field setting unit 527, instead of the user terminal 5 of FIG. 3. However, the user terminal 5 executes the processes of displaying various information to the user and accepting various operations from the user. Each time, the field registration device 4 and the user terminal 5 of FIG. 1 send and receive the necessary information. This configuration reduces the computational load on the user terminal 5. However, this variation may increase the communication processing load on the user terminal 5 with the field registration device 4. Therefore, the field registration device 4 and the user terminal 5 may have both configurations so that the user can use either the above embodiment or this modified example as appropriate depending on the computing power and / or battery capacity of the user terminal 5, the local communication environment, etc.
