(Embodiment 1)
A farm field management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the farm field management system 1000 includes a farm field management device 100 and a terminal 200. The farm field management device 100 is communicatively connected to the terminal 200 and a work device 30 via a network 20, for example the Internet. The work device 30 includes, for example, a crop planting machine, a tractor that pulls a work machine, and the like.

The field management device 100 has field group data 300 that stores multiple pieces of field data representing information about the field in which the work device 30 performs work. The field management device 100 also acquires operation information from the work device 30 and determines a work area 500 related to the work based on the acquired operation information, as shown in FIG. 2. The determined work area 500 may differ from the area of the registered field 400 represented in the field data. For example, even if a change occurs in the area of the actual real field corresponding to the field data, the area of the registered field 400 represented in the field data may not be changed. Also, field data representing a new real field may not be registered in the field group data 300. The work area 500 of the work performed in such a real field, for example, an actual field whose area has been changed or a new actual field, differs from the area of the registered field 400 represented in the field data.

When the area of the actual field differs from the area of the registered field 400 represented in the field data, the user registers field data representing the area of the actual field in the field group data 300. Therefore, when the working area 500 differs from the area represented in the field data of the field group data 300, the field management device 100 supports the user in registering field data related to the actual field based on the working area 500. In this way, the field management system 1000 can support the user in efficient cultivation management.

Here, the operation information includes information that indicates the operating state of the working device 30 when work is being performed in an actual field, and includes information that indicates, for example, the speed, steering angle, engine RPM, ON/OFF status of various clutches, position information of the working device 30 at each time, and the working period. When the working device 30 is a vehicle that tows a work machine, such as a tractor, the operation information may include information such as the PTO (power take-off) RPM when transmitting power to the work machine, and the hitch height and lift arm angle that indicate the attitude of the work machine. The working device 30 may also be a drone that sprays pesticides.

The operation information also includes position information of the work device 30. The work device 30 is equipped with a positioning device, for example a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position of the work device 30 at each time it moves.

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

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

The storage device 140 stores various data for updating the field data stored in the field group data 300, such as the field group data 300 and the field management program 310. The storage device 140 is used as a non-transitory tangible storage medium for storing the field management program 310. The field management program 310 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.

The field group data 300 stores multiple field data. The field data represents information about one registered field 400, and includes attribute information about the registered field 400, area information representing the field area of the registered field 400, work status information, and the like. The attribute information represents, for example, the field name, owner name, and name of the crop being cultivated of the registered field 400. The area information represents, for example, the position and shape of the registered field 400. The work status information represents whether work in the corresponding registered field 400 has been completed. The field name, owner name, crop information, area information, and work status information are stored in association with each other.

The computing device 120 shown in FIG. 1 executes the field management program 310 and is used for various data processing operations for updating the field data related to the registered field 400. For example, the computing device 120 includes a central processing unit (CPU) and the like.

By reading and executing the field management program 310, the computing device 120 realizes a data storage unit 150, a work information determination unit 160, a field detection unit 170, a field registration unit 180, and an output unit 190, as shown in FIG. 4. The data storage unit 150 stores the field group data 300. The work information determination unit 160 acquires operation information from the work device 30 and determines the work area 500. Based on the field group data 300, the field detection unit 170 detects field candidate areas within the work area 500 that differ from the areas represented in the field data of the field group data 300. The field registration unit 180 registers the field data representing the field candidate areas in the field group data 300. The output unit 190 outputs at least a portion of the field data stored in the field group data 300 to the terminal 200.

Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input/output device 210, a computing 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 computing device 220 to execute processing is input to the input/output device 210. The input/output device 210 also outputs the results of the processing executed by the computing device 220. 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.

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 farm field management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the farm field management device 100. The communication device 230 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

The storage device 240 stores various data for registering field data in the field group data 300, such as a display program 320. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 320. The display program 320 may be provided as a computer program product recorded on a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

The computing device 220 reads and executes the display program 320, and cooperates with the input/output device 210 to realize the display unit 250 as shown in FIG. 4. The display unit 250 acquires at least a portion of the field data from the field management device 100 and displays at least a portion of the field data. In addition, the display unit 250 transmits registration information related to the field data to be registered to the field management device 100 based on a registration operation by a user to register the field data.

(Operation of farmland management device)
When the computing device 120 of the farm field management device 100 receives operation information from the work device 30, it reads and executes the farm field management program 310. By executing the farm field management program 310, the computing device 120 executes the processing shown in Fig. 5 which is a farm field management method.

In step S110, the work information determination unit 160 realized by the computing device 120 determines the work area 500 in which the work device 30 performed work and the work type based on the operation information acquired from the work device 30. For example, the work information determination unit 160 determines the work area 500 based on the position information of the work device 30 included in the operation information. For example, the work area 500 is represented by any closed figure, such as a polygon or rectangle, that includes the position represented in the acquired position information. For example, the work area 500 is represented by a figure that surrounds all of the acquired position information.

The work information determination unit 160 may also determine the trajectory of the movement of the work device 30 based on the position information, and determine the work area 500 based on the determined trajectory. For example, the work information determination unit 160 connects the positions indicated in the position information with a line, for example a straight line segment, in the order of the measured time, and determines the obtained line as the trajectory of the movement of the work device 30. The work information determination unit 160 determines an area within a distance of a preset work width from the trajectory as the work area 500. Here, the work width represents the distance from the position of the positioning device provided on the work device 30 to the edge of the area where the work is performed by the work device 30 in a direction perpendicular to the traveling direction of the work device 30.

The work information determination unit 160 also determines the work type of the work performed in the work area 500 based on the operation information. The work type indicates the type of work performed in the work area 500, such as plowing, leveling, fertilizing, planting, etc. For example, the work information determination unit 160 estimates the work type using a trained model obtained by machine learning. In this case, the trained model is trained to determine the work type from the operation information. The work information determination unit 160 may also determine the work type based on the model of the work device 30. In this case, the storage device 140 stores work correspondence data that associates the model of the work device 30 with the work type. The work information determination unit 160 determines the work type based on the work correspondence data.

The work information determination unit 160 may also determine the work period during which work was performed in the work area 500 based on the operation information. For example, the work information determination unit 160 may determine the period from when the engine of the work device 30 starts to when it stops as the work period.

In step S120, the field detection unit 170 extracts the work area 500 where work has been completed in the corresponding registered field 400. For example, the field detection unit 170 detects field data representing the registered field 400 including the work area 500 from the multiple field data stored in the field group data 300. It determines whether the work in the registered field 400 including the work area 500 has been completed based on the time that has elapsed since the time that work was last performed in the area of the registered field 400 in the detected field data. When a predetermined time or more has elapsed since the time that work was last performed in the area of the registered field 400, the field detection unit 170 determines that the work in the registered field 400 including the work area 500 has been completed, and extracts the work area 500 included in the registered field 400 where the work has been determined to have been completed.

The field detection unit 170 may also determine whether work has been completed in the registered field 400 corresponding to the work area 500 based on a user's input operation. For example, the user inputs a work completion operation to the input/output device 210 of the terminal 200 shown in FIG. 1, specifying the work area 500 in which work has been completed in the corresponding registered field 400. When the work completion operation is input to the input/output device 210, the calculation device 220 of the terminal 200 reads and executes the display program 320. Based on the work completion operation, the display unit 250 realized by the calculation device 220 transmits work completion information representing the work area 500 in which work has been completed in the corresponding registered field 400 to the field management device 100. Based on the work completion information, the field management device 100 extracts the work area 500 in which work has been completed in the corresponding registered field 400.

In step S130 shown in FIG. 5, the field detection unit 170 detects, based on the work area 500 and the field group data 300, from among the areas included in the extracted work area 500, candidate field areas to be registered as areas of the registered field 400 represented in the field data. For example, the field detection unit 170 detects, from among the extracted work area 500, candidate field areas having areas not included in areas represented by the multiple field data stored in the field group data 300. In the example shown in FIG. 2, the field detection unit 170 detects work areas 500 that do not overlap with areas of the registered field 400 represented in the field data, for example, the first work area 500-1, the second work area 500-2, and the third work area 500-3.

The field detection unit 170 also detects, as a candidate field area, a working area 500 that includes an area that overlaps with at least a portion of the area of the registered field 400 represented in the field data and an area that does not overlap with the area of the registered field 400. In the example shown in FIG. 2, the field detection unit 170 extracts a fourth working area 500-4 that includes an area that overlaps with a portion of the fourth registered field 400-4 and an area that does not overlap with the area of the fourth registered field 400-4. When the area of the working area 500 included in the area of the registered field 400 represented in the field data is smaller than the area of the registered field 400, the field detection unit 170 extracts this working area 500 as a candidate field area.

For example, when the area of the working area 500 included in the area of the registered field 400 represented in the field data is smaller than a predetermined ratio of the area of the registered field 400, the field detection unit 170 extracts the working area 500 as a candidate field area. In addition, when the area of the working area 500 not included in the area of the registered field 400 represented in the field data is larger than a predetermined ratio of the area of the registered field 400, the field detection unit 170 extracts the working area 500 as a candidate field area. This reduces the influence of measurement errors contained in the acquired position of the working device 30.

The field detection unit 170 may also extract a working area 500 when the area of the working area 500 included in the area of the registered field 400 represented in the field data is smaller than a predetermined area with respect to the area of the registered field 400. The field detection unit 170 may also extract a working area 500 when the area of the working area 500 not included in the area of the registered field 400 represented in the field data is larger than a predetermined area with respect to the area of the registered field 400.

In addition, the field detection unit 170 detects a working area 500 that is entirely included in a part of a registered field 400 represented in the field data as a candidate field area. In the example shown in FIG. 2, the field detection unit 170 extracts a fifth working area 500-5 that is entirely included in a part of a fifth registered field 400-5 as a candidate field area. For example, when the area of the working area 500 included in the area of the registered field 400 represented in the field data is smaller than a predetermined ratio of the area of the registered field 400, the field detection unit 170 extracts this working area 500 as a candidate field area. When the area of a work area 500 included in the area of a registered field 400 represented in the field data is smaller than a predetermined area relative to the area of the registered field 400, the field detection unit 170 may extract this work area 500 as a candidate field area.

In addition, the field detection unit 170 detects a work area 500 including an area that overlaps the entire area of the registered field 400 represented in the field data and an area that does not overlap the area of the registered field 400 as a candidate field area. In the example shown in FIG. 2, the field detection unit 170 detects a sixth work area 500-6 including an area that includes the entire area of the sixth registered field 400-6 and an area that is not included in the area of the sixth registered field 400-6. For example, when the area of the work area 500 that is not included in the area of the registered field 400 represented in the field data is greater than a predetermined ratio of the area of the registered field 400, the field detection unit 170 extracts this work area 500 as a candidate field area. When the area of a work area 500 that is not included in the area of a registered field 400 represented in the field data is larger than a predetermined area relative to the area of the registered field 400, the field detection unit 170 may extract the work area 500 as a candidate field area.

The field detection unit 170 may also detect candidate field data for change representing a registered field 400 whose attribute information should be changed, based on the work area 500 and the field group data 300. In the example shown in FIG. 2, the field detection unit 170 detects candidate field data for change representing a first registered field 400-1, whose area does not overlap with the work area 500, from among the field data stored in the field group data 300.

In step S140 shown in FIG. 5, the output unit 190 outputs field candidate information representing the detected field candidate area to the terminal 200. The output unit 190 may output attribute information corresponding to a registered field 400 corresponding to the field candidate area, for example, a registered field 400 including at least a part of the field candidate area, to the terminal 200. The output unit 190 also outputs at least a part of the change candidate field data representing a registered field 400 whose area does not overlap with the work area 500 to the terminal 200.

In step S150, the display unit 250 of the terminal 200 displays the field candidate information representing the field candidate area acquired from the field management device 100, and accepts a registration operation by the user. For example, the display unit 250 displays an image showing the field candidate area on a map as shown in FIG. 2. The display unit 250 displays an image showing, for example, the area of the registered field 400 represented in the field data stored in the field group data 300 and the work area 500 on a map. The display unit 250 may display the field candidate area in, for example, a different color so as to be distinguishable from the other work areas 500. For example, the display unit 250 highlights the field candidate area compared to the other work areas 500. The display unit 250 may display a list of the field candidate areas.

The user sets the area of the registered field 400 of the field data to be registered, and sets attribute information related to this registered field 400, such as the field name, owner name, and crop name shown in FIG. 3. For example, the user first inputs a selection operation to the input/output device 210 to select a work area 500 to be newly registered as field data. When the selection operation is input, the display unit 250 displays one or more candidate areas of the registered field 400 represented by the field data to be registered based on the selected work area 500. For example, when one of multiple adjacent work areas 500 is selected, the display unit 250 displays each work area 500 and the area obtained by integrating the adjacent work areas 500 as candidate areas for the registered field 400. For example, when the first work area 500-1 is selected, the display unit 250 displays the first work area 500-1, the second work area 500-2, the third work area 500-3, and the area obtained by integrating the three work areas 500 from the first work area 500-1 to the third work area 500-3. The display unit 250 may also display the area obtained by integrating the first work area 500-1 and the second work area 500-2, and the area obtained by integrating the second work area 500-2 and the third work area 500-3, as candidate areas for the registered field 400.

For example, when a working area 500 is selected that includes an area that overlaps with the area of the registered field 400 represented in the field data and an area that does not overlap with the area of the registered field 400, the display unit 250 displays the working area 500 and small areas 510 divided from the working area 500 as candidate areas of the registered field 400, as shown in FIG. 6. For example, when a fourth working area 500-4 is selected, the display unit 250 displays the working area 500, a first small area 510-1 included in the area of the registered field 400 represented in the field data, and a second small area 510-2 not included in the area of the registered field 400, as candidate areas. The display unit 250 may also display the area of the registered field 400 represented in the field data, for example the fourth registered field 400-4, as a candidate area.

When a work area 500 that is entirely contained within a portion of the registered field 400 represented in the field data is selected, the display unit 250 displays the work area 500 as a candidate area. For example, when the fifth work area 500-5 shown in FIG. 2 is selected, the display unit 250 displays the fifth work area 500-5 as a candidate area.

When a work area 500 including multiple areas not included in the area of the registered field 400 represented in the field data, for example the sixth work area 500-6, is selected, the display unit 250 displays the work area 500 and multiple small areas 510 as candidate areas, as shown in FIG. 7. For example, the display unit 250 displays the sixth work area 500-6, a fourth small area 510-4 included in the area of the sixth registered field 400-6, a third small area 510-3 not included in the area of the sixth registered field 400-6, and a fifth small area 510-5. The third small area 510-3 and the fifth small area 510-5 represent areas obtained by dividing the sixth work area 500-6 by the fourth small area 510-4.

Next, the user selects the area of the registered field 400 of the field data to be registered from the displayed area candidates. The display unit 250 determines the selected area candidate as the area of the registered field 400 of the field data to be registered. When the display unit 250 determines the area of the registered field 400 of the field data to be registered, it displays the attribute information of the corresponding field data in order to set attribute information of the registered field 400, such as the owner name and crop name shown in FIG. 3. For example, when the selected work area 500 does not include the area of the registered field 400 of the field data, the display unit 250 displays attribute information of field data representing one or more registered fields 400 whose distance from the selected work area 500 is shorter than a predetermined distance, among the multiple field data. In the example shown in FIG. 2, when the first work area 500-1 is selected, the display unit 250 displays attribute information of the field data representing the registered field 400 closest to the first work area 500-1. The display unit 250 also displays attribute information of the field data representing one or more registered fields 400 whose distance from the first work area 500-1 is less than a predetermined distance.

When the selected work area 500 includes at least a portion of the area of a registered field 400 in the field data, the display unit 250 displays attribute information of the registered field 400 included in the work area 500. In the example shown in FIG. 2, the field data corresponding to the fourth work area 500-4 represents the field data of the fourth registered field 400-4. The field data corresponding to the fifth work area 500-5 represents the field data of the fifth registered field 400-5. The field data corresponding to the sixth work area 500-6 represents the field data of the sixth registered field 400-6.

Finally, the user modifies the displayed attribute information, such as the owner name and crop name, as necessary, and sets it as the attribute information of the registered field 400 represented by the field data to be registered. The display unit 250 determines the attribute information set by the user as the registration information of the field data to be registered. The display unit 250 transmits the determined registration information to the field management device 100. The registration information includes area information representing the area of the registered field 400 corresponding to the field data to be registered.

In addition, in step S150, the display unit 250 displays at least a portion of the change candidate field data that does not overlap the work area 500, and accepts an exclusion operation by the user. For example, as shown in FIG. 2, the display unit 250 displays an area representing a registered field 400 that does not include the work area 500, for example the first registered field 400-1, among the registered fields 400 represented by the multiple field data stored in the field group data 300, in a manner that is distinguishable from areas representing the other registered fields 400. For example, the display unit 250 highlights the area representing the first registered field 400-1 compared to areas representing the other registered fields 400. The display unit 250 may display a list of the registered fields 400 represented by the change candidate field data.

The user selects a registered field 400 of field data to be excluded from the target of cultivation management from the registered fields 400 represented by the change candidate field data, and excludes the field data of the selected registered field 400 from the field data to be subject to cultivation management. The display unit 250 displays attribute information of the selected change candidate field data, such as the owner's name and crop name. The user checks the displayed attribute information and inputs an exclusion operation to exclude the field data from the target of cultivation management. Based on the exclusion operation, the display unit 250 transmits exclusion information representing the change candidate field data corresponding to the selected registered field 400 to the field management device 100.

In step S160 shown in FIG. 5, the field registration unit 180 of the field management device 100 registers the field data represented in the registration information in the field group data 300 based on the registration information related to the field data set by the user. The field registration unit 180 registers the candidate area selected by the user in the field group data 300 as an area of the registered field 400 corresponding to the newly registered field data. The field registration unit 180 also registers the attribute information set by the user, such as the field name, the owner's name, and the crop name of the crop cultivated in the registered field 400, in the field group data 300 as attribute information of the registered field 400 corresponding to the newly registered field data.

Furthermore, the field registration unit 180 excludes the corresponding field data from the field group data 300 based on the exclusion information representing the field data corresponding to the registered field 400 specified by the user's exclusion operation. The field registration unit 180 deletes the corresponding field data from the field group data 300. The field registration unit 180 may also exclude the corresponding field data from the management target without deleting it from the field group data 300.

In step S170, the output unit 190 outputs at least a portion of the field data related to the registered field 400 stored in the field group data 300. The output unit 190 outputs, for example, at least a portion of the newly registered field data, for example area information of the registered field 400, to the terminal 200.

The output unit 190 may also extract the work area 500 in which work was performed during the specified period specified by the user, and output work information representing the extracted work area 500. The output unit 190 may also extract the work area 500 included in the area of the registered field 400 including the work area 500 in which work was performed during the specified period, and include information on the extracted work area 500 in the output work information. For example, the output unit 190 first extracts field data representing the registered field 400 including the work area 500 in which work was performed during the specified period from the multiple field data stored in the field group data 300. Next, the output unit 190 extracts the work area 500 in which work was performed outside the specified period included in the area of the registered field 400 of the extracted field data. The output unit 190 outputs work information including information representing the extracted work area 500 in which work was performed outside the specified period. In the output work information, information representing the work area 500 outside the specified period may be distinguished from information representing the work area 500 during the specified period.

For example, when a user specifies a work area 500 in which work was performed in March, as shown in FIG. 8, the output unit 190 extracts the work area 500 in which work was performed in March, for example, the 11th work area 500-11 in which work was performed on March 21st. The output unit 190 may also extract the 10th work area 500-10 in which work was performed in January but which is included in the area of the 10th registered field 400-10 that includes the 11th work area 500-11.

The output unit 190 may also extract work areas 500 that are closer than a predetermined distance from the work area 500 in which work was performed during the specified period, and include information on the extracted work areas 500 in the output work information. In the output work information, information representing work areas 500 outside the specified period may be distinguished from information representing work areas 500 during the specified period. For example, the output unit 190 may also extract a twelfth work area 500-12 adjacent to an eleventh work area 500-11, in which work was performed in January.

In step S180 shown in FIG. 5, the display unit 250 of the terminal 200 displays at least a portion of the field data acquired from the field management device 100, for example, area information of the registered field 400. The display unit 250 also displays work information representing the extracted work area 500. This allows the user to confirm the newly registered registered field 400 and the work area 500. The display unit 250 may also display the work area 500 for the specified period and the work area 500 outside the specified period in a distinguished manner.

In the example shown in FIG. 8, the eleventh work area 500-11 may be displayed, for example, in a different color to distinguish it from the tenth work area 500-10 and the twelfth work area 500-12. The user can check the work areas 500 in which work was performed in the entire registered field 400. In addition, the user can check the work areas 500 in which work was performed in the area including the work area 500 by displaying all work areas 500 within a specified distance at once.

In this way, the field management system 1000 assists the user in registering field data related to the registered field 400. This allows the user to efficiently register field data and efficiently check the work that has been carried out in the registered field 400.

(Modification)
The configuration described in the embodiment is an example, and the configuration can be changed to the extent that the function is not impaired. For example, the field detection unit 170 may extract the work area 500 based on the work type of the work performed in the work area 500 in step S130. For example, the field detection unit 170 extracts the work area 500 based on the work type that can most symbolically represent the shape of the actual field in the current year, such as planting, sowing, harvesting, etc. This allows the user to specify the cultivated area where the crop actually exists, and therefore the user can perform cultivation management more accurately. In addition, the work area 500 is extracted based on the work type that can distinguish the work area 500 depending on the type of crop to be cultivated, such as planting, sowing, harvesting, etc. This allows the user to specify the crop cultivated in the registered field 400 of the newly registered field data from a combination of information such as the work area and work time, and therefore the user can update the field data appropriately and efficiently.

In addition, in step S130, the field detection unit 170 may extract the work area 500 in which work was performed during the specified period specified by the user. The field detection unit 170 may also extract the work area 500 included in the area of the registered field 400 that includes the work area 500 in which work was performed during the specified period. For example, when the user specifies the work area 500 in which work was performed in March, as shown in FIG. 8, the field detection unit 170 extracts the work area 500 in which work was performed in March, for example, the 11th work area 500-11 in which work was performed on March 21st. The field detection unit 170 may also extract the 10th work area 500-10 in which work was performed in January but that is included in the area of the 10th registered field 400-10 that includes the 11th work area 500-11.

The field detection unit 170 may also extract work areas 500 whose distance from the work area 500 in which work was performed during the specified period is less than a predetermined distance. For example, the field detection unit 170 may also extract a twelfth work area 500-12 adjacent to an eleventh work area 500-11, in which work was performed in January.

In this case, in step S140, the output unit 190 outputs the field candidate information that distinguishes between the work areas 500 in which work was performed during the specified period and the work areas 500 in which work was performed outside the specified period. In step S150, the display unit 250 of the terminal 200 displays an image that distinguishes between the work areas 500 in which work was performed during the specified period and the work areas 500 in which work was performed outside the specified period. This allows the user to confirm the area of the newly registered field 400 in the entire same registered field 400 by displaying the work areas 500 included in the same registered field 400 at once. In addition, by displaying the work areas 500 included within a specified distance at once, the user can confirm the area including the work areas 500 and confirm the area of the newly registered field 400.

The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be modified and/or combined as desired 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 required functions can be realized. For example, some or all of the processing of the farm field management device 100 may be performed by the terminal 200. Also, some or all of the processing of the terminal 200 may be performed by the farm field management device 100.

In addition, some of the processing of the field management device 100 may be omitted. For example, the field detection unit 170 may omit the processing of step S120 shown in FIG. 5. Specifically, the field detection unit 170 may not extract work areas 500 where work has been completed, but may detect potential field areas in step S130 based on all work areas 500 and the field group data 300.

The field detection unit 170 may not detect a registered field 400 that does not include a work area 500, such as the first registered field 400-1 shown in FIG. 2. For example, the field detection unit 170 may detect only the field candidate area without detecting the change candidate field data in step S130 shown in FIG. 5. In this case, the output unit 190 does not output the change candidate field data to the terminal 200 in step S140. Furthermore, the display unit 250 of the terminal 200 does not accept an exclusion operation by the user in step S150.

The field management system 1000 may also omit the processing of step S140 and step S150 shown in FIG. 5. In this case, the field registration unit 180 registers field data in which the detected field candidate area is the area of the registered field 400 in the field group data 300. For example, when there are multiple candidate areas for one work area 500, the field registration unit 180 automatically selects one candidate area and registers the field data in which the selected candidate area is the area of the registered field 400.

In addition, the field detection unit 170 may detect only the change candidate field data without detecting the candidate field area in step S130 shown in FIG. 5. In this case, the output unit 190 does not output the candidate field information representing the candidate field area in step S140. In addition, the display unit 250 of the terminal 200 does not accept a registration operation by the user in step S150.
