Description

Technical Field

[0001] This invention relates to a method for managing farmland information, a management system for farmland information, and a program for managing farmland information. Background Technology

[0002] In recent years, research has been conducted on technologies that use information and communication technologies to efficiently manage information related to field operations.

[0003] Patent document 1 discloses a technology that displays information related to the work being carried out in the field for each working device.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2022-168628

[0005] Information related to operations carried out in the fields is sometimes used not only by the operators but also by buyers of the crops grown on those fields, such as food companies. For example, sometimes operators sign a sales contract with a buyer regarding the harvested crop before planting it, and then deliver the harvested crop to the contracted buyer after harvesting. In such cases, the buyer uses information related to the operations in the fields when they want to confirm the delivery date, quality, etc.

[0006] However, when operators are cultivating crops other than those delivered to contracted buyers, they sometimes cannot easily extract and disclose the information intended for the buyers. Summary of the Invention

[0007] In view of the above, one of the purposes of this disclosure is to easily provide information that can be disclosed to other users from information related to an operation performed by a certain user. Other purposes can be understood from the following description and implementation method.

[0008] One embodiment of the field information management method for achieving the above objectives includes storing field information representing multiple first fields associated with a first user, and one or more operation information related to operations performed in the multiple first fields. Furthermore, the field information management method includes extracting public information related to publicly accessible fields included in the multiple first fields from the one or more operation information. Additionally, the field information management method includes outputting the public information to a second display device used by a second user different from the first user.

[0009] One embodiment of the field information management system for achieving the above objectives includes a data storage unit, a public information extraction unit, and an output unit. The data storage unit stores field information representing multiple first fields associated with a first user, and one or more operation information related to operations performed in the multiple first fields. The public information extraction unit extracts public information related to public fields included in the multiple first fields from one or more operation information. The output unit outputs the public information to a second display device used by a second user, different from the first user.

[0010] In one embodiment for achieving the above objectives, a field information management program causes a computing device to store field information representing multiple first fields associated with a first user, and one or more operation information related to operations performed in the multiple first fields. Furthermore, the field information management program causes the computing device to extract public information related to public fields included in the multiple first fields from the one or more operation information. Finally, the field information management program causes the computing device to output the public information to a second display device used by a second user different from the first user.

[0011] Using the method described above, it is possible to easily provide information that can be made public to other users from information related to a task performed by a particular user. Attached Figure Description

Detailed Implementation

[0029] (Implementation Method)

[0030] The farmland information management system 1000 based on this embodiment of the present invention will be described with reference to the accompanying drawings. In this embodiment, as... Figure 1 As shown, the field information management system 1000 includes a field information management device 100 and one or more terminals 200 used by one or more users 40. The field information management device 100 is communicatively connected to the operating device 30 and one or more terminals 200 via a network 20, such as the Internet.

[0031] The working device 30 performs operations while moving across the field 500. The working device 30 may include, for example, a tractor towing the working machinery. Alternatively, the working device 30 may also include combine harvesters, transplanters, sprayers, etc., integrated with the working machinery. The working device 30 may also include drones that perform agricultural operations by flight, such as pesticide spraying.

[0032] For example, such as Figure 2 As shown, the working device 30 moves along the movement path 600 to perform operations in the field 500. For example, the working device 30 moves from its storage location 560 to the first field 500-1 via the road 570 to perform operations. After completing its operations in the first field 500-1, the working device 30 crosses the road 570 to move to the second field 500-2 to perform operations. Moreover, after completing its operations in the second field 500-2, the working device 30 moves via the road 570 to the third field 500-3 to perform operations. After completing its operations in the third field 500-3, the working device 30 returns to the storage location 560 via the road 570.

[0033] The operating device 30 has a positioning device that measures the machine's position at various times, such as latitude and longitude. The positioning device may include, for example, a GNSS (Global Navigation Satellite System) receiver, a quantum compass, etc., and measures a positioning position 610 representing the machine's location at predetermined intervals (e.g., 1-second intervals). Therefore, the positioning position 610 represents the position on the movement path 600. For example, the operating device 30 measures the positioning position 610 representing the machine's location and outputs the position information representing the measured position to the field information management device 100.

[0034] The field information management device 100 determines information related to the operations performed by the operating device 30 based on location information obtained from the operating device 30. For example, Figure 3As shown, the field information management device 100 determines the movement trajectory 650 of the work device 30 and the work area 660 in which the work device 30 performs its work. In addition, the field information management device 100 can also determine the period (e.g., date) in which the work device 30 performs its work and the type of work performed (e.g., tilling, sowing, transplanting, pesticide spraying, harvesting, etc.).

[0035] here, Figure 1 The more than one terminal 200 shown may include, for example, a first terminal 200-1 used by a first user 40-1, a second terminal 200-2 used by a second user 40-2, and a third terminal 200-3 used by a third user 40-3. For example, the first user 40-1 is associated with multiple fields 500, representing an operator working on the multiple fields 500, a manager of the multiple fields 500, etc. The second user 40-2 represents a purchaser buying crops harvested from a portion of the multiple fields 500, and the third user 40-3 represents a purchaser buying crops harvested from another portion of the multiple fields 500.

[0036] like Figure 3 As shown, the first user 40-1 can, for example, browse information about the operations of all fields 500. On the other hand, the second user 40-2 can only browse information about the operations of fields 500 where the crop to be purchased is grown, such as the first field 500-1 and the second field 500-2. Furthermore, the third user 40-3 can only browse information about the operations of fields 500 where the crop to be purchased is grown, such as the third field 500-3.

[0037] For example, the first user 40-1 selects, among all fields 500, fields 500 that disclose the operation information to the second user 40-2 (e.g., first field 500-1 and second field 500-2). Similarly, the first user 40-1 selects, among all fields 500, fields 500 that disclose the operation information to the third user 40-3 (e.g., third field 500-3).

[0038] The field information management device 100 generates operation information for all fields 500 provided to the first user 40-1. Furthermore, the field information management device 100 extracts information about the fields 500 selected by the first user 40-1 that correspond to the second user 40-2 and the third user 40-3 from the operation information of all fields 500. Thus, the field information management system 1000 can provide a portion of the operation information performed by the operation device 30 to other users 40 (e.g., the second user 40-2, the third user 40-3, etc.). Here, for ease of understanding, when distinguishing between users 40 who disclose information (e.g., the first user 40-1) and users 40 who disclose objects (e.g., the second user 40-2, the third user 40-3), users 40 who disclose information are sometimes referred to as publicly licensed users 41, and users 40 who disclose objects are sometimes referred to as browsing users 42. Therefore, a user 40 who was previously a publicly licensed user 41 may sometimes become a browsing user 42, and a user 40 who was previously a browsing user 42 may sometimes become a publicly licensed user 41.

[0039] Furthermore, the working device 30 can also acquire status information indicating the status of the working device 30 at various times. For example, the working device 30 acquires status information at predetermined intervals (e.g., 10-second intervals). The status information may include, for example, the speed, direction of travel, steering angle, and status of various clutches of the working device 30. Additionally, when the working device 30 is a tractor towing the working machinery, the status information may also indicate the PTO (power take-off) speed when power is transmitted to the working machinery, the hook height indicating the posture of the working machinery, the lifting arm angle, etc. Moreover, the working device 30 can also measure the amount of material used (e.g., seeding rate, planting rate, pesticide and fertilizer spraying rate, etc.) or the amount of material obtained (e.g., harvest rate), and the status information indicates the measured amount of material. The acquired status information is output to the field information management device 100. For example, the status information is output to the field information management device 100 as operational information summarized with location information. Furthermore, the operational information may also include identification information of the working device 30, such as identification ID, manufacturing number, etc.

[0040] (Structure of the farmland information management system)

[0041] right Figure 1 The structure of the land information management device 100 included in the shown land information management system 1000 will be described. For example... Figure 4As shown, the field information management device 100 includes an input / output device 110, a computing unit 120, a communication device 130, and a storage device 140. The field information management device 100 is, for example, a computer including a cloud server. Information for processing by the computing unit 120 is input to the input / output device 110. Furthermore, the input / output device 110 outputs the results of the processing by the computing unit 120. The input / output device 110 may include various input and output devices, such as a keyboard, mouse, microphone, display, speaker, touch panel, etc. The input / output device 110 may also be omitted.

[0042] Communication device 130 is connected to network 20 and communicates with various devices via network 20. For example, communication device 130 transmits information obtained from operating device 30 to computing device 120. Additionally, communication device 130 transmits signals generated by computing device 120 to terminal 200. Communication device 130 may include various interfaces such as NIC (Network Interface Card) and USB (Universal Serial Bus) terminals.

[0043] Storage device 140 stores various data, such as field data 400, operation data 410, and field information management program 420, which are used to provide information to browsing user 42 regarding operations performed by operating device 30 of publicly licensed user 41. Storage device 140 is used as a non-transitory tangible storage medium for storing field information management program 420. Field information management program 420 may be provided as a computer program product recorded on computer-readable storage medium 1, or it may be provided as a computer program product that can be downloaded from a server.

[0044] Field data 400 stores field information related to field 500. For example, the field information associates the identification information of user 40 with the geographical extent of field 500. For example, user 40 associated with the geographical extent of field 500 indicates that user 40 has registered for the geographical extent of field 500. For example, the geographical extent of field 500 can represent the location and shape of field 500 in any form. For example, when the geographical extent of field 500 is represented by a polygon, it is represented by the positions of each vertex (e.g., latitude and longitude). Alternatively, the geographical extent of field 500 can also be represented by the positions of each vertex and information indicating the vertices adjacent to each vertex on the periphery of field 500. The field information can also associate the varieties of crops cultivated in field 500 with the geographical extent of field 500.

[0045] The work data 410 stores information related to the work performed by the work device 30. For example, such as... Figure 5 As shown, the work data 410 stores work information 411 that associates the work period, work device 30, movement trajectory 650, work area 660, and work category. A piece of work information 411, for example, represents the period during which the work device 30 performed one operation. For instance, a piece of work information 411 represents the period from the start of work device 30 to its stop.

[0046] The working device 30 represents information identifying the working device 30 performing the operation (e.g., name, identification ID, etc.). The operation period, for example, represents the time from the start of the working device 30 to its stop. The operation period can also represent the date and time the working device 30 starts. The movement trajectory 650 represents the trajectory of the working device 30 during the operation period. The work area 660 represents the geographical area where the work is performed by the working device 30. The work area 660 can be represented in any form. For example, the work area 660 can be represented as a polygon, defined by the positions of the polygon's vertices (e.g., latitude and longitude) and other adjacent vertices on the periphery of the work area 660. Figure 5 The indicated job category represents the type of operation performed by the work device 30 (e.g., tilling, transplanting, sowing, pesticide spraying, harvesting, etc.). Job information 411 can represent the amount of materials used in the work area 660 (e.g., amount of seeds, transplanting, pesticides, fertilizers, etc.), the amount of materials obtained (e.g., harvest amount), etc. Job information 411 is generated, for example, by the field information management device 100 based on the operation information of the work device 30.

[0047] Figure 4 The computing unit 120 shown reads from the storage device 140 and executes the field information management program 420, performing various data processing tasks to provide a portion of the information on the operations performed by the operating device 30 of the publicly licensed user 41 to the browsing user 42. For example, the computing unit 120 may include a central processing unit (CPU).

[0048] like Figure 6As shown, the arithmetic unit 120, in cooperation with the storage unit 140, implements the data storage unit 150, the operation information generation unit 160, the public field determination unit 170, the public information extraction unit 180, and the output unit 190 by reading and executing the field information management program 420. The data storage unit 150 stores field data 400 and operation data 410. The operation information generation unit 160 generates operation information 411 based on the operation information of the operation device 30. The public field determination unit 170 determines the fields 500 (e.g., the first field 500-1, etc.) that are open to browsing users 42 other than the public license user 41 associated with the field 500 as public fields. The public information extraction unit 180 extracts public information representing operation-related information in the public fields from the operation-related information of the operation device 30. In order to disclose to the browsing user 42, the output unit 190 outputs display information representing operation-related information in the public fields to the terminal 200 of the browsing user 42.

[0049] Next, for Figure 1 The structure of the terminal 200 shown will be explained. For example... Figure 7 As shown, terminal 200 includes an input / output device 210, a processing unit 220, a communication device 230, and a storage device 240. Terminal 200 may include, for example, a computer, a tablet computer, or a mobile phone. Information for processing by the processing unit 220 is input to the input / output device 210. Furthermore, the input / output device 210 outputs the results of the processing performed by the processing unit 220. The input / output device 210 may include various input and output devices, such as a keyboard, mouse, microphone, display, speaker, and touch panel.

[0050] The communication device 230 is connected to the network 20 and communicates with various devices via the network 20. For example, the communication device 230 transmits display information obtained from the field information management device 100 to the computing device 220. Additionally, the communication device 230 transmits signals generated by the computing device 220 to the field information management device 100. The communication device 230 may include various interfaces such as transceivers for wireless communication (LAN, cellular network, etc.), NICs (Network Interface Cards), and USB terminals.

[0051] Storage device 240 stores various data, such as display program 430, used for displaying information obtained from field information management device 100. Storage device 240 is used as a non-transitory tangible storage medium for storing display program 430. Display program 430 may be provided as a computer program product recorded on computer-readable storage medium 2, or it may be provided as a computer program product that can be downloaded from a server.

[0052] The arithmetic unit 220 reads from the storage device 240 and executes the display program 430 to perform various data processing for displaying information. For example, the arithmetic unit 220 may include a central processing unit (CPU).

[0053] like Figure 6 As shown, the arithmetic unit 220, in cooperation with the storage unit 240 and the input / output unit 210, implements the display unit 250 by reading and executing the display program 430. The display unit 250 displays display information obtained from the field information management device 100. In addition, the display unit 250 receives public license information indicating public fields selected by the public license user 41 associated with the field 500 to be disclosed to the browsing user 42.

[0054] (The operation of the farmland information management system)

[0055] The operation of the land information management system 1000 will be explained. First, the process of user 40 registering land 500 in land data 400 will be explained. User 40 registering land 500 includes both publicly licensed users 41 and browsing users 42. Publicly licensed users 41, for example, register land 500 for which operations are to be performed. Browsing users 42 register land 500 for which they wish to browse operation information 411.

[0056] For example, user 40 inputs an operation to the input / output device 210 of terminal 200 for registering land 500. The processing unit 220 of terminal 200 reads from the storage device 240 and executes the display program 430 based on the user 40's operation. If the display program 430 is executed, the processing unit 220 begins processing as part of the land information management method.

[0057] For example, the display unit 250, implemented by the computing device 220, receives information related to the farmland 500 registered by the user 40. The display unit 250 displays an image representing a map on the input / output device 110. The user 40 specifies the geographical extent of the farmland 500 in the displayed map. For example, when representing the geographical extent of the farmland 500 with a polygon, the user 40 selects the vertices of the polygon on the map in an order around its outer perimeter. The display unit 250 outputs information representing the geographical extent of the specified farmland 500 to the farmland information management device 100. For example, the display unit 250 outputs information representing the location (e.g., latitude and longitude) of the selected vertices on the map and the order of selection to the farmland information management device 100. Furthermore, the information output to the farmland information management device 100 includes identification information representing the user 40. Furthermore, the method by which the user 40 specifies the geographical extent of the farmland 500 can be any method.

[0058] The data storage unit 150 of the field information management device 100 stores information related to the field 500 in the field data 400 based on information obtained from the terminal 200. For example, the data storage unit 150 stores field information representing the geographical extent of the field 500 in the field data 400 in association with the identification information representing the user 40.

[0059] In this way, the field information management system 1000 stores information indicating the geographical extent of the field 500 specified by the user 40 in the field data 400, associating it with the user 40. Additionally, the display unit 250 of the terminal 200 can also receive information indicating the varieties of crops cultivated in the field 500 as information related to the registered field 500. In this case, information indicating the varieties of crops cultivated in the field 500 is transmitted from the terminal 200 to the field information management device 100 and stored in the field data 400 in association with the geographical extent of the field 500 via the data storage unit 150 of the field information management device 100. The information related to the registered field 500 may also include other arbitrary information.

[0060] (Generation of job information)

[0061] Next, the process of storing operation information 411 related to the operation performed by the working device 30 in the operation data 410 will be described. For example, when user 40 (e.g., publicly licensed user 41) uses the working device 30 to perform operations in the field 500, the user starts the working device 30 and moves it to the field 500. For example, if the prime mover (e.g., engine, motor) is started, the working device 30 measures its position and status at various times. The working device 30 outputs operation information indicating the measured position, status, and time to the field information management device 100. For example, when the prime mover stops, the working device 30 summarizes and outputs the operation information obtained from the start of the prime mover to its stop. Alternatively, the working device 30 may output the operation information sequentially.

[0062] If the computing unit 120 of the field information management device 100 receives operation information from the operating device 30, it reads from the storage device 140 and executes the field information management program 420. If the field information management program 420 is executed, the computing unit 120 begins to function as part of the field information management method. Figure 8 The processing shown.

[0063] First, in step S110, the job information generation unit 160, implemented by the computing device 120, determines the movement trajectory 650 of the job device 30 in a job based on the operation information (especially position information) of the job device 30. For example, the job information generation unit 160 based on... Figure 2 The positioning position 610 shown is used to determine the movement trajectory 650. For example, the work information generation unit 160 determines the movement trajectory 650 as a line obtained by connecting the positioning positions 610 of the work device 30 at each time in the measured order. For example, the movement trajectory 650 represents a line obtained by connecting two adjacent positioning positions 610 at the measured time with straight line segments.

[0064] Next, in Figure 8 In step S120, the job information generation unit 160 determines the job area 660 where the job device 30 performed the work based on the operation information of the job device 30. For example, the job information generation unit 160 extracts the operation information of the job device 30 during operation from the operation information of the job device 30 using any method. For example, the job information generation unit 160 extracts the operation information of the job device 30 from the operation information of the job device 30. Figure 2 The positioning position 610 shown is the positioning position 610 when the working device 30 performs operations, such as the positioning position 610 measured between the first positioning position 610-1 and the second positioning position 610-2.

[0065] For example, the work information generation unit 160 extracts the operation information of the work device 30 when its speed is within the speed range during operation from the operation information of the work device 30. In this case, the speed of the work device 30 corresponding to the operation information represents the speed of the work device 30 at the positioning position 610 indicated by the position information included in the operation information. Here, the speed of the work device 30 at each positioning position 610 can also be determined based on the distance between that positioning position 610 and other positioning positions 610 adjacent to the measured time, and the interval between the times of measuring the two positioning positions 610. The work information generation unit 160 can also obtain the speed of the work device 30 from the status information of the work device 30.

[0066] Additionally, the operation information generation unit 160 can also extract operation information indicating the location 610 within the field 500 as operation information for the operation device 30 during operation. Furthermore, the operation information generation unit 160 can also use the status information of the operation device 30 to extract operation information for the operation device 30 during operation. For example, the operation information generation unit 160 can extract operation information indicating that the operation device 30 is performing operations (e.g., operation information indicating that the machinery of the tillage operation device 30 is descending) as operation information for operation.

[0067] Next, the operation information generation unit 160 determines the geographical extent of the operation area 660 using any method based on the location information of the classified operation information groups. For example, the operation information generation unit 160 determines the geographical extent of the operation area 660 for a single operation information group. For instance, the operation information generation unit 160 determines the area containing all the location positions 610 represented by an operation information group as the geographical extent of the operation area 660. The operation information generation unit 160 determines the geographical extent of the operation area 660 where operations were performed by the operation device 30 using any method based on the extracted operation information containing all the location positions 610 represented by the location information. For instance, the operation information generation unit 160 classifies the extracted operation information into operation information groups determined when operations were performed in the same field 500. For instance, the operation information generation unit 160 uses any clustering method to classify the location positions 610 represented by the extracted operation information into one or more operation information groups.

[0068] The geographical extent can also be determined by any method. For example, the job information generation unit 160 determines the geographical extent of the job area 660 as the convex hull relative to all corresponding positioning locations 610. Here, the convex hull includes all corresponding positioning locations 610, displaying the smallest convex polygon. Alternatively, the job information generation unit 160 can also determine the geographical extent of the job area 660 as the concave hull relative to multiple positioning locations 610. For example, the concave hull can be formed by any algorithm, such as representing an alpha shape for multiple positioning locations 610.

[0069] Furthermore, the work information generation unit 160 can also define the geographical area that has been expanded from the convex or concave hull as the work area 660 based on the work width of the work device 30. For example, the work information generation unit 160 can also define the geographical area that has been expanded from the outline of the convex or concave hull by half the work width as the work area 660. In addition, the work width represents the distance of the geographical area where the work device 30 performs work in a direction orthogonal to the travel direction of the work device 30.

[0070] Next, in Figure 8 In step S130, the operation information generation unit 160 determines the operation category of the operation performed in each operation area 660 based on the classified operation information groups. The operation information generation unit 160 determines one operation category for each operation information group. The operation information generation unit 160 determines the operation category of the operation performed by the operation device 30 using any method based on the operation information groups. For example, the operation information generation unit 160 uses a learning model learned to output operation categories based on operation information to determine the operation category. Alternatively, the operation information generation unit 160 can also determine the operation category based on the type of operation device 30. For example, when the operation device 30 is a combine harvester, the operation information generation unit 160 determines that the operation performed by the operation device 30 is harvesting. In this case, the type of operation device 30, such as information indicating its model, can also be included in the operation information.

[0071] Next, in step S140, the job information generation unit 160 generates a job information based on the determined movement trajectory 650, the geographical range of the job area 660, the job category, etc. Figure 5The work information 411 is shown. For example, the work information generation unit 160 determines the work period during which the work device 30 performed the work based on the operation information. For example, the work information generation unit 160 determines the work period as the time between the initial measurement and the last measurement of the operation information. In addition, the work information generation unit 160 determines the information representing the work device 30 (e.g., name, identification ID, etc.) based on the identification information (e.g., manufacturing number) of the work device 30 included in the operation information. In this case, the work information generation unit 160 stores a correspondence table that establishes a correspondence between the identification information of the work device 30 represented by the operation information and the information of the work device 30 included in the work information 411, and determines the information of the work device 30 based on the correspondence table. Furthermore, the work information generation unit 160 may also determine detailed information related to the work, such as information indicating the seeding amount, planting amount, harvest amount, etc., based on the status information of the work device 30, and include the determined information in the work information 411. In addition, the work information 411 may also include information indicating the variety of the crop cultivated in the work area 660. In this case, for example, the job information generation unit 160 extracts fields 500 that overlap with the geographical area of ​​the job area 660 from the field data 400, and identifies the variety of crops cultivated in the fields 500 as the variety of crops cultivated in the job area 660. The identified job information 411 is stored in the job data 410 by the job information generation unit 160.

[0072] Next, in Figure 8 In step S150, the output unit 190 outputs the job information 411 to the terminal 200. For example, the output unit 190 outputs information representing an image showing the geographical extent of the job area 660 on a map to the terminal 200. Additionally, the output unit 190 outputs information contained in the job information 411, such as information relating to the geographical extent of the job area 660, indicating the job period, job type, etc., to the terminal 200.

[0073] Next, in step S160, the display unit 250 of the terminal 200 displays the operation information 411 obtained from the field information management device 100. For example, such as... Figure 3 As shown, the display unit 250 displays an image on a map representing the geographical extent of the work area 660. Additionally, the display unit 250 can also display the movement trajectory 650 of the work device 30 on the displayed image. Furthermore, the display unit 250 can also display information indicating the work period and work type in association with the geographical extent of the work area 660.

[0074] In this way, the field information management system 1000 generates operation information 411 based on the operation information of the operation device 30 and stores it in the operation data 410. In addition, the field information management system 1000 can also display the generated operation information 411.

[0075] (Provide job information to browsing users)

[0076] Next, the method by which the field information management system 1000 provides a portion of the information on the operations performed by the work device 30 based on the operation information 411 to the browsing user 42 will be described. For example, a publicly licensed user 41 associated with field 500 (e.g., the user 40 of the work device 30 that performed the operations in field 500) selects a field 500 for which the browsing user 42 is authorized to browse the operation information 411. Thus, the browsing user 42 is able to browse the operation information 411 of the selected field 500.

[0077] In this scenario, for example, a licensed user 41 associated with field 500 inputs an operation to the input / output device 210 of terminal 200 to browse field 500 for selecting licensed operation information 411. The processing unit 220 of terminal 200 reads and executes the display program 430 based on the operation performed by the licensed user 41, initiating a field information management method. Figure 9 The processing shown.

[0078] First, in step S210, the display unit 250, implemented by the computing device 220, receives public license information for the farmland 500 representing the public operation information 411. For example, the display unit 250 displays information indicating that the farmland 500 has been registered by the public license user 41. For example, as... Figure 10 As shown, display unit 250 displays an image representing the geographical extent of the farmland 500 registered on the map. (As shown...) Figure 10 As shown, the display unit 250 can also display operation information 411 in addition to displaying the geographical extent of the field 500. The display unit 250 can also display the registered field 500 in tabular form.

[0079] The authorized user 41 selects the field 500 to be viewed by the authorized browsing user 42 from the image displayed on the input / output device 210. For example, when the authorized browsing user 42 (e.g., the second user 40-2) is browsing the operation information 411 of the first field 500-1 and the second field 500-2, the authorized user 41 selects the first field 500-1 and the second field 500-2.

[0080] If field 500 is selected, the display unit 250 requests, for example, information about the browsing user 42. For example, the display unit 250 displays an image of an input field indicating that the browsing user 42 can input identification information. The authorized user 41 enters information (e.g., identification ID, name, etc.) about the browsing user 42 (e.g., second user 40-2) in the displayed input field.

[0081] If field 500 is selected and the information of browsing user 42 is entered, the display unit 250 determines that it has received public access permission information indicating the selected field 500 and the information of browsing user 42. The display unit 250 outputs the received public access permission information to the field information management device 100.

[0082] Furthermore, information indicating that the land 500 was registered by the publicly licensed user 41 is obtained from the land data 400 of the land information management device 100. For example, the display unit 250 of the terminal 200 can also obtain information indicating that the land 500 was registered by the publicly licensed user 41 from the land information management device 100 based on the operation of the publicly licensed user 41.

[0083] Next, in Figure 9 In step S220, the public land determination unit 170 of the land information management device 100 determines whether there exists a land 500 among the lands 500 registered by the browsing user 42 as indicated in the public license information that corresponds to all the lands 500 indicated in the public license information. For example, the public land determination unit 170 extracts information indicating the lands 500 registered by the browsing user 42 from the land data 400. The public land determination unit 170 determines whether there exists a land 500 among the extracted lands 500 of the browsing user 42 that has a geographical range corresponding to the geographical range of the lands 500 indicated in the public license information. For example, the public land determination unit 170 determines whether there exists a land 500 among the lands 500 of the browsing user 42 that has a geographical range overlapping with the geographical range of the lands 500 indicated in the public license information. For example, in Figure 10 In the example shown, the public land determination unit 170 determines whether the land 500 corresponding to the first land 500-1 and the second land 500-2 selected by the public license user 41 has been registered by the browsing user 42.

[0084] For example, when the browsing user 42's land 500 includes land 500 whose geographical area overlaps at least partially with the geographical area of ​​the land 500 in the publicly licensed information, the publicly licensed land determination unit 170 determines that there exists a land 500 corresponding to the land 500 in the publicly licensed information. For example, when the browsing user 42 registers a land 500 corresponding to the land 500 selected by the publicly licensed user 41, the publicly licensed land determination unit 170 determines that there exists a corresponding land 500. For example, when the geographical area of ​​the land 500 selected by the publicly licensed user 41 overlaps at least partially with the geographical area of ​​the land 500 registered by the browsing user 42, the publicly licensed land determination unit 170 determines that there exists a corresponding land 500. When a corresponding land 500 exists (yes), the publicly licensed land determination unit 170 executes... Figure 9 The process shown in step S230.

[0085] On the other hand, when the browsing user 42's land 500 does not include any land 500 whose geographical range overlaps at least partially with the geographical range of the land 500 in the publicly licensed information, the publicly licensed land determination unit 170 determines that there is no land 500 corresponding to the land 500 in the publicly licensed information. For example, when there is no land 500 whose geographical range overlaps at least partially with the geographical range of the land 500 selected by the publicly licensed user 41 and has been registered by the browsing user 42, the publicly licensed land determination unit 170 determines that there is no corresponding land 500. When there is no corresponding land 500 (No), the publicly licensed land determination unit 170 performs the processing of step S240.

[0086] exist Figure 9 In step S230, the public field determination unit 170 determines the public field 500 representing the field for disclosing job information 411 to the designated browsing user 42 based on the public license information. For example, the public field determination unit 170 determines the field 500 represented by the public license information as the public field for disclosing job information 411 to the browsing user 42 represented by the public license information. For example, the public field determination unit 170 determines the first field 500-1 and the second field 500-2 selected by the public license user 41 as public fields. If the processing of step S230 ends, the processing proceeds to step S270.

[0087] When no corresponding field 500 exists in step S220, in step S240, the field disclosure determination unit 170 outputs a confirmation request to confirm whether to disclose the operation information 411 related to the field 500 in the disclosure license information to the browsing user 42. For example, when the field 500 selected by the disclosure license user 41 includes a field 500 that the browsing user 42 has not registered, the field disclosure determination unit 170 confirms whether the operation information 411 of that field 500 can be disclosed to the browsing user 42. Therefore, the confirmation request information is, for example, used to confirm whether the operation information 411 of the field 500 can be disclosed to the browsing user 42 even though the browsing user 42 has not registered the field 500 selected by the disclosure license user 41. For example, the confirmation request information represents a field 500 that the browsing user 42 has not registered among the more than one field 500 represented by the disclosure license information. In addition, the confirmation request information also represents the browsing user 42 represented by the disclosure license information.

[0088] For example, in Figure 10 In the example shown, assume that browsing user 42 registered field 500 corresponding to the first field 500-1, but did not register field 500 corresponding to the second field 500-2. In this case, the public field determination unit 170 outputs confirmation request information indicating browsing user 42 and the second field 500-2 to the terminal 200.

[0089] Next, in Figure 9 In step S250, the display unit 250 of the terminal 200 receives confirmation information indicating whether the operation information 411 of the selected field 500 can be disclosed to the designated browsing user 42, based on the confirmation request information. For example, the display unit 250 displays information indicating the browsing user 42 and the field 500 (e.g., the second field 500-2) indicated by the confirmation request information. The display unit 250 displays an image for confirming whether the operation information 411 of the field 500 indicated by the confirmation request information can be disclosed to the browsing user 42 indicated by the confirmation request information.

[0090] For example, such as Figure 11 As shown, the display unit 250 displays an image on a map representing the geographical extent of the field 500 indicated by the confirmation request information. Additionally, the display unit 250 displays a confirmation image 700 for confirming whether operation information 411 regarding the geographical extent of the field 500 has been publicly displayed to the browsing user 42.

[0091] The user 41 who grants public access inputs confirmation information indicating whether to disclose the operation information 411 of the field 500 represented by the confirmation request information to the input / output device 210. For example, in Figure 11In the example shown, the licensed user 41 selects "Yes" when disclosing the operation information 411 of the second field 500-2 to the browsing user 42, and selects "No" when not disclosing the operation information 411 of the second field 500-2 to the browsing user 42. When "Yes" is selected, the display unit 250 determines that it has received confirmation information indicating that the operation information 411 of the second field 500-2 has been disclosed to the browsing user 42. On the other hand, when "No" is selected, the display unit 250 determines that it has received confirmation information indicating that the operation information 411 of the second field 500-2 has not been disclosed to the browsing user 42.

[0092] The display unit 250 outputs the received confirmation information to the field information management device 100. Furthermore, when the confirmation request information indicates multiple fields 500, the display unit 250 can also display a confirmation image 700 for each field 500. In this case, the confirmation information indicates whether the operation information 411 for each field 500 should be disclosed to the browsing user 42.

[0093] Next, in Figure 9 In step S260, the public land determination unit 170 of the land information management device 100 determines the public land for which the operation information 411 is made public to the browsing user 42 based on the public permission information and the confirmation information. For example, the public land determination unit 170 determines the public land from the land 500 represented by the public permission information after excluding the land 500 that is designated as not public in the confirmation information. Therefore, public land refers to the land 500 among the land 500 represented by the public permission information, the land 500 for which the corresponding land 500 was registered in step S220, and the land 500 that was indicated for public disclosure by the public permission user 41 in step S250. If the processing of step S260 ends, the processing proceeds to step S270. In addition, the public land determination unit 170 may also register the land 500 that was indicated for public disclosure in the confirmation information as the land 500 registered by the browsing user 42 in the land data 400.

[0094] In step S270, the public information extraction unit 180 extracts public information representing information related to operations in the public field from the operation information 411. For example, such as... Figure 12 As shown, the public information extraction department extracts 180... Figure 5 The portion of the work information 411 shown that is included within the geographical area of ​​the open fields (e.g., first field 500-1 and second field 500-2). For example, the open information extraction unit 180 extracts the portion of the movement trajectory 650 represented by the work information 411 that overlaps with the geographical area of ​​the open fields as the open trajectory 655. For example, as Figure 12As shown, the public information extraction unit 180 extracts the portion of the movement trajectory 650 that includes the geographical area of ​​the first field 500-1 as the first public trajectory 655-1. Additionally, the public information extraction unit 180 extracts the portion of the movement trajectory 650 that includes the geographical area of ​​the second field 500-2 as the second public trajectory 655-2. Furthermore, when a portion of the movement trajectory 650 from the first public trajectory 655-1 to the second public trajectory 655-2 is not included in the work area 660, this portion can also be extracted as a public trajectory 655 (e.g., a third public trajectory 655-3). This indicates that the information of the extracted public trajectory 655 is included in the public information. Therefore, a public trajectory 655 represents the portion of the movement trajectory 650 that excludes at least the geographical area of ​​undisclosed fields other than publicly disclosed fields among the multiple fields 500 stored in the field data 400.

[0095] Furthermore, the public information extraction unit 180 extracts the work area 660 corresponding to the publicly disclosed farmland from one or more work areas 660 represented by the work information 411 as a publicly disclosed work area 665. For example, the public information extraction unit 180 extracts work areas 660 having a geographical extent that overlaps with at least a portion of the geographical extent of the publicly disclosed farmland as publicly disclosed work areas 665. Figure 10 In the example shown, at least a portion of the geographical extent of the first work area 660-1 overlaps with a portion of the geographical extent of the first field 500-1, which is an open field. Furthermore, at least a portion of the geographical extent of the second work area 660-2 overlaps with a portion of the geographical extent of the second field 500-2, which is also an open field. Therefore, as... Figure 12 As shown, the public information extraction unit 180 extracts the first work area 660-1 and the second work area 660-2 as the first public work area 665-1 and the second public work area 665-2. Furthermore, information indicating that the extracted public work areas 665 are included in the public information.

[0096] In addition, the Public Information Extraction Department 180 Figure 5 The work data 410 shown also extracts information associated with the public work area 665, such as work period and work category, as part of the public information. Furthermore, in the public information, each piece of information, such as work period and work category, is also represented in association with the public work area 665.

[0097] In this way, the public information extraction unit 180 extracts public information from the operation information 411 based on the geographical range of the public field.

[0098] Next, in Figure 9In step S280, the output unit 190 outputs display information representing the extracted public information to the terminal 200, such as the terminal 200 used by the browsing user 42 (e.g., the second terminal 200-2). For example, as shown... Figure 12 As shown, the display information may also show an image on a map representing the geographical extent of the publicly disclosed work area 665 indicated by the publicly disclosed information. Additionally, the display information may also show an image on a map representing the publicly disclosed track 655. The display information may also include work information 411 related to the publicly disclosed field, such as the work period and work type.

[0099] Next, in Figure 9 In step S290, the display unit 250 of the user 42's terminal 200 (e.g., the second terminal 200-2) displays the display information obtained from the field information management device 100 on the input / output device 210. For example, as shown... Figure 12 As shown, the display unit 250 displays an image on a map representing the geographical extent of the open work area 665 and the open track 655. The display unit 250 can also display detailed information related to the work in the open work area 665, such as work period, work type, and planting quantity, in association with the geographical extent of the open work area 665. Additionally, the display unit 250 can display detailed information about the work in the open work area 665 in tabular form, corresponding to the open work area 665 represented by the displayed information. Furthermore, by browsing the detailed information selected by the user 42 to be displayed in tabular form, the display unit 250 can also display an image on a map representing the open track 655 corresponding to the selected detailed information. Alternatively, the display unit 250 can display an image representing the geographical extent of the field 500 corresponding to the open work area 665, and display detailed information about the work in the open work area 665 in association with the geographical extent of the field 500, instead of displaying the open work area 665 itself.

[0100] In this way, the field information management system 1000 provides the browsing user 42 with the information corresponding to the field 500 from the operation information 411 related to the operation performed by the operation device 30. For example, the field information management system 1000 provides the browsing user 42 with the information corresponding to the field 500 from the operation information 411 related to one operation performed by the operation device 30. Therefore, publicly licensed users 41 associated with multiple fields 500, such as operators and owners of the fields 500, can easily disclose the operation information 411 of the fields 500 to other browsing users 42.

[0101] Similarly, when browsing user 42 is a third user 40-3, and publicly discloses the operation information 411 of field 500 (e.g., third field 500-3), the field information management system 1000 executes the same action. Figure 9The processing is shown. In this case, as... Figure 13 As shown, the display unit 250 of the terminal 200 displays the operation information 411 of the third field 500-3, such as the third public operation area 665-3 and the third public track 655-3. Here, in step S210, the public access user 41 may also specify multiple browsing users 42, such as the second user 40-2 and the third user 40-3. In this case, the public access information will represent the information of each browsing user 42 in association with the field 500 to which the operation information 411 is disclosed to each browsing user 42.

[0102] In addition, the land information management device 100 of the land information management system 1000 can also be used in... Figure 8 When the processing shown generates operation information 411 related to the already identified public field, then the following steps are executed. Figure 9 The steps S270 and subsequent processing are shown. In this case, the operation information 411 of the public field can be disclosed to the browsing user 42 as soon as possible. In addition, the display unit 250 can also display multiple operation information 411 of the public field (e.g., operation period, operation category, etc.) in tabular form. For example, when the geographical area of ​​the public field represented on the map is selected, the display unit 250 can also display multiple operation information 411 of the selected public field.

[0103] In addition, Figure 9 In step S280 shown, the output unit 190 of the field information management device 100 can also output display information to the terminal 200 (e.g., the first terminal 200-1) used by the publicly licensed user 41. For example, the output unit 190 can also distinguish between... Figure 8 In step S150, the job information 411 is output, and display information indicating public information is output instead. In this case, the licensed user 41 can easily confirm the licensed job information 411.

[0104] (Request for disclosure of job information)

[0105] exist Figure 9In step S290, the display unit 250 of the terminal 200 (e.g., the second terminal 200-2) used by the browsing user 42 can also accept requests for disclosure of land 500 for which job information 411 is not displayed. For example, when the job information 411 for the land 500 that should be displayed is not displayed in the display information shown on the input / output device 210 of the terminal 200, the browsing user 42 will select the operation input for that land 500 to the input / output device 210. For example, the browsing user 42 selects the land 500 for which job information 411 is requested from the land 500 registered in the land data 400 of the land information management device 100. The display unit 250 outputs disclosure request information indicating the selected land 500 to the land information management device 100. The disclosure request information may also include information indicating the browsing user 42 using the terminal 200. In addition, the disclosure request information may also include information indicating the disclosure license user 41 requesting disclosure.

[0106] If the public land determination unit 170 of the land information management device 100 obtains public land request information, it outputs the obtained public land request information to, for example, the terminal 200 (e.g., the first terminal 200-1) of the public land licensee 41. For example, the public land determination unit 170 outputs information indicating the browsing user 42 represented by the public land request information and the land 500 represented by the public land request information.

[0107] The display unit 250 of the terminal 200 of the authorized user 41 accepts permission information indicating whether to grant permission for the disclosure of operation information 411 based on information obtained from the field information management device 100. For example, the display unit 250 displays an image on a map showing the geographical extent of the field 500 represented by the disclosure request information. In addition, the display unit 250 displays an image confirming whether to disclose the operation information 411 to the browsing user 42 who requested the disclosure, in association with the geographical extent of the field 500 represented by the disclosure request information.

[0108] The user 41, who grants the right to disclose the operation information 411 of the field 500 shown in the image, inputs this information to the input / output device 210, indicating whether or not to disclose it to the requesting user 42. When information indicating the disclosure of the operation information 411 is input, the display unit 250 determines that it has received permission information indicating permission to disclose. Conversely, when information indicating that the operation information 411 should not be disclosed is input, the display unit 250 determines that it has received permission information indicating that disclosure is not permitted.

[0109] The display unit 250 outputs permission information, indicating whether the disclosure of operation information 411 is permitted, to the field information management device 100. The permission information may also include information about the field 500 that is the object and the browsing user 42 who requested the disclosure.

[0110] The public land determination unit 170 of the land information management device 100 determines the land 500 for which the operation information 411 will be disclosed to the browsing user 42 who requested disclosure, based on the permission information. For example, the public land determination unit 170 determines the land 500 for which disclosure is permitted in the permission information as public land. Here, if the land 500 for which disclosure is permitted has not been registered by the public disclosure licensee 41, the public information extraction unit 180 may also store the information representing the land 500 associated with the public disclosure licensee 41 in the land data 400. For example, the public information extraction unit 180 may also store the land 500 for which disclosure is permitted as a land 500 registered by the public disclosure licensee 41 in the land data 400. Subsequent processing and Figure 9 The steps S270 and subsequent processes shown are the same, so detailed descriptions are omitted.

[0111] In this way, the field information management system 1000 can also determine public information based on requests from browsing users 42.

[0112] (Notification of abnormal data)

[0113] Additionally, when the publicly disclosed work information 411 contains abnormal data, the browsing user 42 can also request confirmation of the work device 30 from the publicly licensed user 41 via the field information management system 1000. For example, the browsing user 42 selects the work information 411 containing abnormal data and inputs the operation to the input / output device 210. The browsing user 42 can also further input information explaining the abnormal data (e.g., information representing explanatory text) to the input / output device 210. The display unit 250 outputs the input information as abnormal information to the field information management device 100. The abnormal information may also include information about the work device 30 represented by the selected work information 411. Furthermore, the abnormal information may also include information identifying the publicly licensed user 41 who disclosed the licensed work information 411.

[0114] The output unit 190 of the field information management device 100 outputs information requesting confirmation of the operation device 30 represented by the abnormal information to the terminal 200 of the publicly licensed user 41 who disclosed the permitted operation information 411, based on the abnormal information. For example, the output unit 190 may also transmit the abnormal information obtained from the terminal 200 of the browsing user 42 (e.g., the second terminal 200-2) to the terminal 200 of the publicly licensed user 41 who disclosed the permitted operation information 411 (e.g., the first terminal 200-1).

[0115] The display unit 250 of the terminal 200 of the licensed user 41 displays information (e.g., anomaly information) obtained from the field information management device 100 on the input / output device 210. For example, the display unit 250 displays that the operation information 411 of the operation device 30 indicated by the anomaly information contains abnormal data. In addition, the display unit 250 may further display a request for confirmation of the operation device 30 indicated by the anomaly information. If the licensed user 41 browses the anomaly information displayed on the input / output device 210, they can investigate the corresponding operation device 30 to confirm whether there is an anomaly.

[0116] In this way, when browsing user 42 discovers abnormal data in job information 411, the field information management system 1000 can quickly urge user 40 using the corresponding job device 30 to confirm the job device 30.

[0117] (Variation example)

[0118] The embodiments and variations described above are merely examples. The structures described in each embodiment and variation can be arbitrarily changed and / or combined without affecting the functionality. Furthermore, as long as the required functionality can be achieved, some of the functions described in the embodiments and variations can be omitted.

[0119] This demonstrates the operation of the field information management device 100 when it receives operational information from the operating device 30. Figure 8 The examples shown are not limited to this one. Figure 8 The processing shown can also be performed at any interval (e.g., one day). For example, the computing unit 120 of the field information management device 100 can also perform the processing at a predetermined time each day. Figure 8 The process is shown. In this case, the period during the job can also indicate the execution... Figure 8 The processing interval shown extends from the initial start of the work device 30 to the final stop. Additionally, in this case, work information 411 will be displayed during the execution... Figure 8 The processing intervals shown are treated as one job, and information related to that job is represented.

[0120] In addition, Figure 8 In step S130 shown, the operation information generation unit 160 of the field information management device 100 can also determine an operation category based on all operation information related to an operation.

[0121] exist Figure 9In step S210 shown, the display unit 250 of the terminal 200 of the public license user 41 associated with the field 500 can also accept public license information indicating that the field 500 is authorized for browsing in any way. For example, the public license user 41 may first designate the browsing user 42 of the public operation information 411, and then the display unit 250 may accept the public license information by selecting the field 500 of the public operation information 411.

[0122] Alternatively, in step S210, the display unit 250 may also accept public license information by specifying a region that includes more than one field 500 instead of directly selecting the field 500 in the public operation information 411. In this case, the display unit 250 accepts information indicating the geographical scope of the region that includes more than one field 500. For example, the geographical scope of the region can be represented by the name of the region, such as the name of an administrative division. In this case, the field data 400 stores the names of the regions containing each field 500, and the public field determination unit 170 of the field information management device 100 processes the field 500 registered by the public license user 41 and included in the name of the specified region as the field 500 selected by the public license user 41.

[0123] Alternatively, the geographical extent of a region can be represented by a range specified on a map, for example, when represented by a polygon, by selecting the positions of the vertices of the polygon in order around its perimeter. In this case, the public land determination unit 170 of the land information management device 100 processes the land 500 registered by the public license user 41 and included within the specified range as the land 500 selected by the public license user 41 based on the land data 400.

[0124] Furthermore, in step S210, the display unit 250 may accept not only the public permission information for the field 500, but also public permission information including other conditions, such as the period, type of operation, and type of crop cultivated. In this case, in step S270, the public information extraction unit 180 extracts operation information 411 that meets the conditions indicated by the public permission information and generates the extracted operation information 411 as public information. For example, when a period is specified in the public permission information, the public information extraction unit 180 excludes operation information 411 that indicates an operation period that does not overlap with the specified period. For example, the public information extraction unit 180 extracts only operation information 411 that indicates an operation period that overlaps with at least a portion of the specified period. In addition, when the type of operation is specified in the public permission information, the public information extraction unit 180 extracts only operation information 411 that indicates the type of operation specified.

[0125] exist Figure 9In step S220 shown, an example is illustrated where the public land determination unit 170 of the land information management device 100 determines a field 500 that overlaps at least partially with the field 500 in the public license information as the corresponding field 500, but this is not a limitation. For example, the public land determination unit 170 may also determine a field 500 that overlaps with the field 500 in the public license information by a predetermined proportion or more as the corresponding field 500. For example, the public land determination unit 170 may also determine a field 500 whose overlapping area with the field 500 in the public license information is at least a threshold proportion relative to the area of ​​the field 500 in the public license information as the corresponding field 500. For example, the public land determination unit 170 determines an overlap area representing the area where the geographical range of the field 500 registered by the browsing user 42 overlaps with the geographical range of the field 500 in the public license information. When the ratio of the overlapping area to the area of ​​the geographical range of the publicly licensed land 500 is above a threshold, the publicly licensed land determination unit 170 determines the land 500 registered by the browsing user 42 as the corresponding land 500. Additionally, when the ratio of the overlapping area to the area of ​​the geographical range of the land 500 registered by the browsing user 42 is above a threshold, the publicly licensed land determination unit 170 determines the land 500 registered by the browsing user 42 as the corresponding land 500. Furthermore, when the ratio of the overlapping area to the area of ​​the geographical range encompassed by the land 500 registered by the browsing user 42 or the land 500 in the publicly licensed information is above a threshold, the publicly licensed land determination unit 170 may also determine the registered land 500 as the corresponding land 500.

[0126] exist Figure 9In step S270 shown, an example is illustrated where the public information extraction unit 180 of the field information management device 100 extracts a work area 660 having a geographical extent that overlaps with at least a portion of the geographical extent of the public field as a public work area 665, but this is not a limitation. For example, the public information extraction unit 180 may also extract a work area 660 that overlaps with the geographical extent of the public field by a predetermined proportion or more as a public work area 665. For example, the public information extraction unit 180 may also extract a work area 660 whose overlapping area with the public field is at least a threshold proportion relative to the area of ​​the public field as a public work area 665. For example, the public information extraction unit 180 determines an overlapping area representing the area where the geographical extent of the public field overlaps with the geographical extent of the work area 660. When the ratio of the overlapping area to the area of ​​the geographical extent of the public field is at least a threshold proportion, the public information extraction unit 180 extracts the work area 660 as a public work area 665. Furthermore, when the ratio of the overlapping area to the area of ​​the geographical range of the work area 660 is above a threshold, the public information extraction unit 180 can also extract the work area 660 as the public work area 665. When the ratio of the overlapping area to the area of ​​the public field or the geographical range contained in the work area 660 is above a threshold, the public information extraction unit 180 can also extract the work area 660 as the public work area 665.

[0127] Alternatively, the public information extraction unit 180 can also extract the area within the geographical range of the work area 660 that overlaps with the geographical range of the public field as the public work area 665. In this case, the area where the geographical range of the work area 660 overlaps with the geographical range of the public field becomes the geographical range of the public work area 665.

[0128] exist Figure 9 In step S270 shown, the public information extraction unit 180 of the field information management device 100 can also generate public information based on the operation information of the operating device 30 representing the location 610 of the public field. For example, such as Figure 14 As shown, the public information extraction unit 180 extracts operation information representing the positioning positions 610 contained in the public fields (e.g., the first field 500-1 and the second field 500-2) from the operation information of the operating device 30. For example, the public information extraction unit 180 extracts operation information corresponding to the positioning positions 610 measured from the time of measuring the first positioning position 610-1 contained in the first field 500-1 to the time of measuring the second positioning position 610-2. The public information extraction unit 180 extracts operation information corresponding to the positioning positions 610 measured from the time of measuring the fourth positioning position 610-4 contained in the second field 500-2 to the time of measuring the fifth positioning position 610-5.

[0129] Furthermore, suppose the public information extraction unit 180 determines that the working device 30 has not performed any work from the second positioning position 610-2 last measured in the first field 500-1 to the fourth positioning position 610-4 initially measured in the second field 500-2. In this case, the public information extraction unit 180 may further extract the operation information corresponding to the positioning positions 610 measured from the time of measuring the second positioning position 610-2 to the time of measuring the fourth positioning position 610-4, such as the third positioning position 610-3.

[0130] The public information extraction unit 180 generates public information related to operations in the public field based on the extracted operational information. The method for generating the public information is similar to... Figure 8 The method for generating job information 411 from step S110 to step S140 is the same, so detailed descriptions are omitted.

[0131] exist Figure 9 In step S210 shown, an example is illustrated where a licensed user 41 selects a field 500 for public access information 411. However, the field information management device 100 can also select a field 500 for public access information. For example, the licensed user 41 inputs the operation of selecting a browsing user 42 to the input / output device 210 of the terminal 200. The display unit 250 of the terminal 200 outputs the public access information indicating the browsing user 42 to the field information management device 100. Furthermore, the public access information may also include information indicating the licensed user 41.

[0132] If public permission information representing browsing user 42 is obtained, the public land determination unit 170 of the land information management device 100 determines public land based on the land data 400. For example, the public land determination unit 170 extracts the land 500 registered by public permission user 41 and the land 500 registered by browsing user 42 from the land data 400. The public land determination unit 170 determines the land 500 whose geographical extent overlaps with that of browsing user 42's land 500 as public land. For example, the public land determination unit 170 determines the land 500 of public permission user 41 whose geographical extent overlaps with at least a portion of the geographical extent of browsing user 42's land 500 as public land.

[0133] Additionally, the public land determination unit 170 can also determine public land as land where the overlap between the public licensee's land 500 and the browsing user's land 500 exceeds a predetermined ratio. For example, the public land determination unit 170 determines the overlap area, which represents the area where the geographical range of the browsing user 42's land 500 overlaps with the geographical range of the public licensee's land 500. When the ratio of the overlap area to the geographical range of the public licensee's land 500 is a threshold or higher, the public land determination unit 170 determines that public licensee's land 500 as public land. Furthermore, when the ratio of the overlap area to the geographical range of the browsing user 42's land 500 is a threshold or higher, the public land determination unit 170 can also determine that public licensee's land 500 as public land. When the ratio of the overlapping area to the area of ​​the geographical range contained in the field 500 of browsing user 42 or the field 500 of publicly licensed user 41 is above a threshold, the publicly licensed user 41's field 500 may also be determined as publicly licensed field.

[0134] Additionally, the public land determination unit 170 can also confirm with the public licensee 41 whether to disclose the operation information 411 of the land 500 extracted from the land data 400 as a public land. In this case, for example, the public land determination unit 170 outputs information indicating the land 500 extracted from the land data 400 as a public land to the public licensee 41's terminal 200. The display unit 250 of the terminal 200 displays the information obtained from the land information management device 100. For example, the display unit 250 displays an image on a map showing the geographical extent of the land 500 extracted as a public land. The public licensee 41 selects the land 500 for which the operation information 411 is permitted to be disclosed to the browsing user 42 from the displayed image. Information indicating the selected land 500 is transmitted from the terminal 200 to the land information management device 100. The public land determination unit 170 of the land information management device 100 determines the land 500 selected by the public license user 41 as public land based on information obtained from the terminal 200.

[0135] It shows Figure 5 The job data 410 shown is only an example of job information 411 related to the publicly licensed user 41, but it may also store job information 411 related to other users 40, such as browsing user 42. In this case, the job information 411 includes information indicating the related user 40. Figure 8In step S140, the operation information generation unit 160 of the field information management device 100 includes information about the user 40 associated with the operation device 30 in the operation information 411. In this case, the operation information generation unit 160 maintains a mapping table that establishes a correspondence between the identification information of the operation device 30 and the user 40, and determines the user 40 based on this mapping table. Furthermore, in Figure 9 In step S270 shown, the public information extraction unit 180 of the field information management device 100 extracts the operation information 411 of the public licensed user 41 from the operation data 410, and extracts public information from the extracted operation information 411.

[0136] Additionally, the publicly licensed user 41 can also select information from the various details included in the work information 411, such as the work period, work device 30, movement trajectory 650, work area 660, and work category, to select the information that the licensed browsing user 42 can view. For example, in Figure 9 In step S210, the authorized user 41 selects the information viewed by the authorized browsing user 42 in the job information 411 as detailed public information. This detailed public information is included in the authorized public information and is output to the field information management device 100. Furthermore, in step S270, the public information extraction unit 180 of the field information management device 100 extracts only the information represented by the detailed public information in the job information 411 as public information. In this case, if the job area 660 is not included in the public information, such as... Figure 15 As shown, the display unit 250 displays operation information 411, such as operation period and operation category, in association with the geographical range of the corresponding field 500.

[0137] Alternatively, if the browsing user 42 wants to modify the publicly disclosed job information 411, they can authorize the publicly licensed user 41 to modify the job information 411. As a result, the publicly disclosed information extracted from the job information 411 is also modified. Furthermore, the publicly disclosed job information 411 can also be generated separately from the job information 411 stored in the job data 410. In this case, the browsing user 42 can also modify the publicly disclosed information without authorizing the publicly licensed user 41 to modify the job information 411.

[0138] For example, the field information management device 100 may also perform some or all of the processing of the terminal 200. The terminal 200 may also perform some or all of the processing of the field information management device 100. The terminal 200 may also be assembled into the operating device 30. The field information management program 420 may also include a display program 430.

[0139] The land information management system 1000 may also exclude the terminal 200, and display information on an external terminal not included in the land information management system 1000. When the terminal 200 performs all the processing of the land information management device 100, the land information management device 100 may also be omitted.

[0140] For example, even if the land 500 selected by the public licensee 41 includes land 500 that the browsing user 42 has not registered, steps S220 and the processes from steps S240 to S260 can be omitted without confirming the public licensee 41's access. In this case, for example, step S230 is performed after the process in step S210.

[0141] The field information management system 1000 can also obtain part or all of the operation information 411 from other systems. In this case, it can also be omitted. Figure 8 The processing shown.
