Summary of the Invention

Problems to be Solved by the Invention

[0005] The work type estimated by the technique described in Patent Document 1 may be different from the work type of the work actually performed. Therefore, a user, for example, a worker, a field owner, etc., sets whether the estimated work type is the same as the work type of the work actually performed. Here, when work is being carried out in many fields, the user may not be able to easily grasp the fields for which the work type has been confirmed and the fields for which it has not been confirmed.

[0006] In view of the above situation, one of the objectives of the present disclosure is to assist the user in grasping the fields for which the work type has been confirmed and the fields for which it has not been confirmed. Other objectives can be understood from the following description and the explanation of the embodiments.

Means for Solving the Problems

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

[0008] A work management method according to one embodiment for achieving the above objective includes storing work data (300) that represents work performed in a first work area (400-1), including confirmed work types and information associated with the first work area (400-1), and estimated work types that are estimated to be performed in a second work area (400-2) but are not yet confirmed, including information associated with the second work area (400-2). The work management method also includes displaying an image on a map that distinguishes between the first work area (400-1) corresponding to confirmed work types and the second work area (400-2) corresponding to estimated work types that are not yet confirmed.

[0009] A work management system (1000) according to one embodiment for achieving the above objective comprises a data storage unit (150) and a display unit (250). The data storage unit (150) stores work data (300) that represents work performed in a first work area (400-1), including confirmed work types and information associated with the first work area (400-1), and estimated work types that are estimated to be performed in a second work area (400-2) but are not yet confirmed, including information associated with the second work area (400-2). The display unit (250) displays an image on a map that distinguishes between the first work area (400-1) corresponding to confirmed work types and the second work area (400-2) corresponding to estimated work types that are not yet confirmed.

[0010] A work management program (310) according to one embodiment for achieving the above objective causes the arithmetic unit (120) to store work data (300) representing work performed in the first work area (400-1), including confirmed work types and information associated with the first work area (400-1), and estimated work types that are estimated to be performed in the second work area (400-2) but are not yet confirmed, including information associated with the second work area (400-2). The work management program (310) also causes the arithmetic unit (120) to display an image on a map that distinguishes between the first work area (400-1) corresponding to confirmed work types and the second work area (400-2) corresponding to estimated work types that are not yet confirmed. [Effects of the Invention]

[0011] According to the above configuration, users can efficiently check the types of work registered in the work management device. [Brief explanation of the drawing]

[0012] [Figure 1] This is a schematic diagram of a work management system in one embodiment. [Figure 2] This figure shows a work area displayed by a terminal in one embodiment. [Figure 3] In one embodiment, this is a graph showing the quantity of work area for each type of work. [Figure 4] This diagram shows the structure of the work data in one embodiment. [Figure 5] This diagram shows a functional block that is executed by a work management system in one embodiment. [Figure 6] This is a flowchart illustrating the processing performed by the work management system in one embodiment. [Figure 7] In one embodiment, this is a graph showing the quantity of work area for each type of work. [Modes for carrying out the invention]

[0013] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Figure 1, the work management system 1000 comprises a work management device 100 and a terminal 200. The work management device 100 is communicated with the terminal 200 and the work device 30 via a network 20, for example, the Internet.

[0014] The work management device 100 acquires operational information from the work device 30 and estimates work-related information, such as the work area, work period, and work type, based on the acquired operational information. The work period represents the period during which the work device 30 performed work in the field, for example, from the start of the engine of the work device 30 until it stops. The work type represents the type of work performed in the field, for example, tilling, leveling, fertilizing, planting, etc. The work device 30 includes, for example, a tractor that tows the work machinery. The work machinery includes, for example, a plow or rotary tiller for tilling, a harrow for leveling, a broadcaster for fertilizing, and a transplanter for planting.

[0015] Terminal 200 acquires work-related information from the work management device 100 and provides the acquired work-related information to users, such as workers or field owners. For example, as shown in Figure 2, terminal 200 displays an image representing multiple work areas 400 on a map. Terminal 200 displays in a way that distinguishes between a first work area 400-1, where the user has confirmed the type of work, and a second work area 400-2, where the user has not confirmed the type of work. For example, the color of the area representing the first work area 400-1, where the type of work has been confirmed, is different from the color of the area representing the second work area 400-2, where the type of work has not been confirmed. This allows the user to easily understand the second work area 400-2, where the type of work has not been confirmed, and its proportion.

[0016] Further, as shown in FIG. 3, the terminal 200 graphically displays an overall quantity 510 representing the quantity of work areas 400 where work has been performed for each type of work. Also, the quantity of the work area 400 may be separately represented as an undetermined quantity 520 representing the quantity of the second work area 400-2 for which the work type has not been confirmed and a determined quantity 530 representing the quantity of the first work area 400-1 for which the work type has been confirmed. Thereby, the user can easily confirm the tendency of the work types being performed in the plurality of work areas 400. Also, for each type of work, the user can easily confirm the ratio of the second work area 400-2 for which the work type has not been confirmed, and furthermore, can confirm the tendency of the estimated work type. The terminal 200 may display a list of the overall quantity 510 representing the quantity of the work areas 400 where work has been performed for each type of work.

[0017] Here, the operation information includes information representing the operating state of the work device 30 when working in the field, for example, information representing the speed of the work device 30, the steering angle, the engine speed, the ON / OFF status of various clutches, the position information of the work device 30 at each time, the working period, and the like. When the work device 30 is a vehicle that pulls a work machine, for example, a tractor, the operation information may include information such as the PTO (power take-off) speed when transmitting power to the work machine, the hitch height indicating the attitude of the work machine, and the lift arm angle.

[0018] Also, the operation information includes the position information of the work device 30. The work device 30 includes a positioning device, for example, a receiver of GNSS (Global Navigation Satellite System), and acquires position information representing the position of the work device 30 at each time when it moves.

[0019] (Configuration of the Work Management System) The configuration of the work management device 100 included in the work management system 1000 shown in FIG. 1 will be described. The work management device 100 includes an input / output device 110, an arithmetic device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information for the arithmetic device 120 to execute processing is input to the input / output device 110. Further, the input / output device 110 outputs the result of the processing executed by the arithmetic device 120. The input / output device 110 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like. The input / output device 110 may be omitted.

[0020] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 130 transfers the operation information acquired from the work device 30 to the arithmetic device 120. Further, it transfers the signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces such as, for example, a NIC (Network Interface Card), a USB (Universal Serial Bus).

[0021] The storage device 140 stores various data for determining the work type representing the work performed in the work area 400, for example, work data 300, and a work management program 310. The storage device 140 is used as a non-transitory tangible storage medium that stores the work management program 310. The work 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.

[0022] The work data 300 includes data related to field work, such as data calculated from operational information from the work equipment 30. For example, as shown in Figure 4, the work data 300 stores work area information representing the work area 400 (e.g., the location and shape of the work area 400), work area information representing the work area of ​​the work area 400, work period information representing the work period, work type, and registration status information representing the registration status of the work type. The work area information, work period information, work type, and registration status information are stored in relation to each other.

[0023] The registration status indicates whether the work type has been determined or not. For example, in the work data 300 in Figure 4, "Determined" in the registration status for work area 400 of "Area A" indicates that the work type has been determined to be "plowing". In work area 400 of "Area C", "Not Determined" in the registration status indicates that the work type has not been determined to be "plowing". Hereafter, a determined work type may be referred to as a determined work type.

[0024] The arithmetic unit 120 shown in Figure 1 is used for various data processing to execute the work management program 310 and determine the type of work performed in the work area 400. For example, the arithmetic unit 120 includes a central processing unit (CPU).

[0025] The arithmetic unit 120 reads and executes the work management program 310, thereby realizing a data storage unit 150, an estimation unit 160, a confirmation unit 170, an aggregation unit 180, and an output unit 190, as shown in Figure 5. The data storage unit 150 stores work data 300. The estimation unit 160 acquires operational information from the work device 30 and estimates the work type. The confirmation unit 170 confirms the work type based on confirmation information indicating that the user has confirmed the work type. The aggregation unit 180 aggregates the quantity of work areas 400 where work has been performed for each work type. The output unit 190 outputs area display information representing the work areas 400 to the terminal 200.

[0026] Next, the configuration of terminal 200 will be described. As shown in Figure 1, terminal 200 comprises an input / output device 210, an arithmetic unit 220, a communication device 230, and a storage device 240. Terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information for the arithmetic unit 220 to perform processing is input to the input / output device 210. The input / output device 210 also outputs the results of the processing performed by the arithmetic unit 220. The input / output device 210 includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, touch panel, etc.

[0027] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 230 transfers information acquired from the work management device 100 to the arithmetic unit 220. It also transfers signals generated by the arithmetic unit 220 to the work management device 100. The communication device 230 includes various interfaces such as a NIC (Network Interface Card) and a USB (Universal Serial Bus).

[0028] The storage device 240 stores various data, such as a display program 320, for displaying the work area 400 where the work device 30 has performed work. 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 as a computer program product downloadable from a server. The display program 320 may also be provided recorded on storage medium 1.

[0029] The arithmetic unit 220 reads and executes the display program 320, and in cooperation with the input / output device 210, realizes the display unit 250 as shown in Figure 5. The display unit 250 acquires area display information representing the work area 400 from the work management device 100 and displays the area display information representing the work area 400. The display unit 250 also transmits confirmation information to the work management device 100 to confirm the type of work performed in the work area 400 based on user operation.

[0030] (Operation of the work management device) When the arithmetic unit 120 of the work management device 100 receives operational information from the work device 30, it reads and executes the work management program 310. By executing the work management program 310, the arithmetic unit 120 performs the work management method shown in Figure 6.

[0031] In step S110, the estimation unit 160 determines the work area 400 and the work period based on the operation information acquired from the work device 30. For example, the estimation unit 160 determines the work area 400 based on the position information of the work device 30 included in the operation information. For example, the work area 400 is represented by an arbitrary closed shape that includes the position represented in the acquired position information, such as a polygon or rectangle. For example, the work area 400 is represented by a shape that encloses all of the acquired position information. The work area information representing the determined work area 400 is newly stored in the work data 300 shown in Figure 4 by the estimation unit 160.

[0032] Furthermore, the estimation unit 160 determines the work period to be from the time the work device 30 is started until the time the work device 30 is stopped. The estimation unit 160 stores the work period information representing the determined work period in the work data 300 in association with the newly added work area information.

[0033] The estimation unit 160 also stores in the work data 300 the workers who performed work in the work area 400. The estimation unit 160 has worker correspondence data that associates the work device 30 with the worker, and determines the worker based on the work device 30 that transmitted the operation information.

[0034] In step S120 shown in Figure 6, the estimation unit 160 estimates an estimated work type representing the type of work performed in the work area 400 based on the operational information. For example, the estimation unit 160 estimates the estimated work type using a trained model obtained by machine learning. In this case, the trained model is trained to estimate the estimated work type from the operational information. Alternatively, the estimation unit 160 may estimate the estimated work type based on the model of the work device 30. In this case, the storage device 140 stores work-corresponding data that associates the model of the work device 30 with the estimated work type. The estimation unit 160 estimates the estimated work type based on the work-corresponding data. The estimated work type is associated with work area information representing the work area 400 by the estimation unit 160 and stored in the work data 300 shown in Figure 4. The estimation unit 160 also sets the corresponding registration status of the work data 300 to "Undetermined".

[0035] In step S130 shown in Figure 6, the output unit 190 outputs area display information to the terminal 200, which is associated with the registration status information of the work area information stored in the work data 300. For example, the output unit 190 outputs area display information that distinguishes between a first work area 400-1, which indicates a registration status of "confirmed," and a second work area 400-2, which indicates a registration status of "unconfirmed." The area display information includes not only newly added work area information but also previously stored work area information.

[0036] In step S140, the display unit 250 of the terminal 200 displays an image representing the work area 400 on a map, as shown in Figure 2, based on the area display information acquired from the work management device 100, and accepts the user's operation to confirm the type of work. For example, the display unit 250 displays an image that distinguishes between the first work area 400-1, for which the type of work has been confirmed, and the second work area 400-2, for which the type of work has not been confirmed. The user can easily identify the second work area 400-2, for which the type of work has not been confirmed.

[0037] When a confirmation operation is input to the input / output device 210, the display unit 250 transmits confirmation information representing the correct work type to the work management device 100. Once the confirmation information is transmitted, the process moves to step S150 shown in Figure 6. For example, the user selects a second work area 400-2, whose work type has not yet been determined, to the input / output device 210 of the terminal 200. When the second work area 400-2 is selected, the display unit 250 displays work information 410 representing the estimated work type of the second work area 400-2, corresponding to the selected second work area 400-2, as shown in Figure 2. The user confirms the displayed estimated work type. If the displayed estimated work type is the same as the work type of the work performed in the corresponding second work area 400-2, the user inputs a confirmation operation to confirm the work type, for example, by selecting the confirmation button 411, to the input / output device 210. When the estimated work type differs from the work type of the work performed in the corresponding second work area 400-2, the user inputs a change operation to the input / output device 210, for example, by selecting the change button 412, in order to change the work type. After performing the change operation, the user inputs the correct work type to the input / output device 210. Based on the confirmation operation or change operation, the display unit 250 outputs confirmation information representing the correct work type to the work management device 100. When a confirmation operation is input to the input / output device 210, the confirmation information indicates that the estimated work type of the selected second work area 400-2 is correct. When a change operation is input to the input / output device 210, the confirmation information indicates the correct work type of the selected second work area 400-2.

[0038] In step S140 shown in Figure 6, the display unit 250 also accepts a statistical display operation to display statistical information representing the quantity of work area 400 for each type of work. If a statistical display operation is entered without a confirmation operation being entered, the display unit 250 sends request information requesting statistical information to the work management device 100. Once the request information is sent, the process moves to step S160.

[0039] In step S150, the confirmation unit 170 of the work management device 100 confirms the work type of the second work area 400-2 based on confirmation information representing the correct work type. Specifically, the confirmation unit 170 obtains the second work area 400-2 represented in the confirmation information and the correct work type. In the work data 300 shown in Figure 4, the confirmation unit 170 sets the correct work type in the second work area 400-2 represented in the confirmation information and changes the registration status to "confirmed". For example, when a confirmation operation, such as selecting the confirmation button 411, is entered, the confirmation unit 170 changes the corresponding registration status to "confirmed". When a change operation is entered, the confirmation unit 170 changes the work type of the second work area 400-2 to the work type represented in the confirmation information and changes the registration status to "confirmed".

[0040] In step S160 shown in Figure 6, the aggregation unit 180 aggregates the quantity of the work area 400 for each work type based on the work data 300 shown in Figure 4. For example, first the aggregation unit 180 extracts one or more work types stored in the work data 300. In the example shown in Figure 4, the aggregation unit 180 extracts "plowing" and "weeding" as work types stored in the work data 300.

[0041] Next, the aggregation unit 180 aggregates the quantities of work areas 400 that correspond to one or more extracted work types from the work areas 400 stored in the work data 300. In the example shown in Figure 4, the aggregation unit 180 obtains "4" as the quantity of work areas 400 whose work type is "plowing". The aggregation unit 180 also obtains "1" as the quantity of work areas 400 whose work type is "weeding".

[0042] Furthermore, based on the work data 300, the aggregation unit 180 aggregates the quantity of the first work area 400-1 corresponding to the confirmed work type and the quantity of the second work area 400-2 corresponding to the unconfirmed work type for each work type. In the example shown in Figure 4, the aggregation unit 180 obtains "2" as the quantity of the first work area 400-1 where the work type is "plowing" and the registration status is "confirmed". The aggregation unit 180 obtains "2" as the quantity of the second work area 400-2 where the work type is "plowing" and the registration status is "unconfirmed". The aggregation unit 180 obtains "1" as the quantity of the first work area 400-1 where the work type is "weeding" and the registration status is "confirmed". The aggregation unit 180 obtains "0" as the quantity of the second work area 400-2 where the work type is "weeding" and the registration status is "unconfirmed".

[0043] In step S170 shown in Figure 6, the output unit 190 outputs statistical information representing the quantity of work area 400 for each type of work to the terminal 200. The statistical information may represent the quantity of work area 400 by distinguishing between the quantity of first work area 400-1 corresponding to a confirmed work type whose work type has been determined, and the quantity of second work area 400-2 corresponding to an estimated work type whose work type has not been determined, for each type of work.

[0044] In step S180, the display unit 250 of the terminal 200 displays statistical information acquired from the work management device 100 on the input / output device 210. As shown in Figure 3, the display unit 250 displays the total quantity 510 representing the quantity of the work area 400 where work has been performed, the undetermined quantity 520 representing the quantity of the second work area 400-2 where the work type has not been confirmed, and the confirmed quantity 530 representing the quantity of the first work area 400-1 where the work type has been confirmed. As shown in Figure 3, the display unit 250 may also represent the total quantity 510 using the undetermined quantity 520 and the confirmed quantity 530, and represent the ratio of the undetermined quantity 520 to the total quantity 510. Alternatively, the display unit 250 may display the ratio of the undetermined quantity 520 to the total quantity 510 as a numerical value. By checking the image displayed on the input / output device 210, the user can grasp the proportion of work areas 400 where the work type has not been confirmed for each work type.

[0045] In this way, the work management system 1000 assists users in confirming the type of work.

[0046] (modified version) The configuration described in the embodiment is just one example, and the configuration can be changed as long as it does not impede functionality. For example, when the display unit 250 of the terminal 200 displays the quantity of work areas 400 for each type of work shown in Figure 3, it may display the quantity of the first work area 400-1, for which the type of work has been determined, and the quantity of the second work area 400-2, for which the type of work has not been determined, without distinguishing between them.

[0047] The display unit 250 may display the area of ​​the work area 400 instead of the quantity of the work area 400 in the graph shown in Figure 3. In this case, in step S160 shown in Figure 6, the aggregation unit 180 of the work management device 100 aggregates the area of ​​the work area 400 for each type of work based on the work data 300 shown in Figure 4 to calculate the total area. The aggregation unit 180 also aggregates the area of ​​the first work area 400-1 corresponding to the confirmed work type and the area of ​​the second work area 400-2 corresponding to the unconfirmed work type for each type of work to calculate the total area of ​​the first work area 400-1 and the total area of ​​the second work area 400-2. In step S170, the output unit 190 outputs statistical information representing the area of ​​the work area 400 for each type of work to the terminal 200. The statistical information may represent the area of ​​the work area 400 by distinguishing between the area of ​​the first work area 400-1 corresponding to a confirmed work type for which the work type has been determined, and the area of ​​the second work area 400-2 corresponding to an estimated work type for which the work type has not been determined. In step S180, the display unit 250 of the terminal 200 displays the statistical information on the input / output device 210.

[0048] Furthermore, as shown in Figure 7, the display unit 250 may distinguish between workers who performed work in the work area 400 and display the quantity of work area 400 for each type of work. In the example shown in Figure 7, the first worker-specific graph 600-1 shows the quantity of work area 400 performed by worker a for each type of work. The second worker-specific graph 600-2 shows the quantity of work area 400 performed by worker b for each type of work. The worker-specific graph 600 may distinguish between an undetermined quantity 620 representing the quantity of the second work area 400-2 where the type of work has not been confirmed, and a confirmed quantity 630 representing the quantity of the first work area 400-1 where the type of work has been confirmed. The display unit 250 may use the undetermined quantity 620 and the confirmed quantity 630 to represent the total quantity 610, and may also represent the ratio of the undetermined quantity 620 to the total quantity 610. This allows the user to confirm the type of work performed in the work area 400 on a worker-by-worker basis. Furthermore, users can easily compare the confirmation rate of workers who are checking the type of work with the confirmation rates of other workers. For example, a user can notify workers whose confirmation rate is lower than that of other workers to check the type of work. In this case, the aggregation unit 180 of the work management device 100 distinguishes workers, aggregates the quantities of work areas 400 for each type of work, and outputs statistical information representing the aggregated quantities to the terminal 200.

[0049] The display unit 250 may, instead of displaying the worker, distinguish between work area groups that classify multiple work areas 400 and display the quantity of work areas 400 for each work type. Here, a work area group includes multiple work areas 400 classified based on the similarity between two work areas 400. The similarity indicates whether the work performed in two work areas 400 where work of the same work type was performed is similar.

[0050] For example, the aggregation unit 180 of the work management device 100 calculates the similarity between two work areas 400 based on the work data 300 shown in Figure 4. For example, the similarity is calculated using the distance between the two work areas 400 and the time difference between the times when work was performed in the two work areas 400. For example, the similarity may be calculated based on a two-dimensional distance with the distance between the work areas 400 and the time difference as one axis each. Specifically, the aggregation unit 180 calculates the Euclidean distance, which is calculated by taking the square root of the value obtained by adding the square of the time difference to the square of the distance. The aggregation unit 180 calculates the similarity by calculating the reciprocal of the calculated Euclidean distance. Alternatively, any distance, such as the Manhattan distance, may be used instead of the Euclidean distance.

[0051] In this case, the aggregation unit 180 classifies the work areas 400 according to their similarity in step S160 shown in Figure 6. For example, the work areas 400 are classified so that two work areas 400 with a similarity score less than a threshold are included in the same work area group. The aggregation unit 180 then aggregates the quantity of work areas 400 for each work type, separating them into work area groups. In step S170, the aggregation unit 180 outputs statistical information representing the aggregated quantities to the terminal 200. The display unit 250 of the terminal 200 displays the quantity of work areas 400 for each work type, distinguishing the workers based on the statistical information.

[0052] The display unit 250 may also display the quantity of work areas 400 in which work was performed on a predetermined date. In this case, the aggregation unit 180 aggregates the quantity of work areas 400 in which work was performed on a predetermined date for each type of work, and outputs statistical information representing the aggregated quantity to the terminal 200.

[0053] The work area 400 shown in Figure 2 may represent a field. In this case, the work area 400 in the work data 300 shown in Figure 4 represents a field, and in step S110 shown in Figure 6, the estimation unit 160 determines the field where the work was performed from the position information of the work device 30. For example, the estimation unit 160 determines the field where the work was performed as the field that includes the position where the work device 30 performed the work. The display unit 250 displays the number of fields where the work was performed.

[0054] A single field may contain multiple work areas 400. For example, in step S160 shown in Figure 6, the aggregation unit 180 of the work management device 100 determines that the work type for a corresponding field is determined when the registration status of all work areas 400 included in a single field is "determined". The aggregation unit 180 determines that the work type for a corresponding field is not determined when the registration status of at least one work area 400 included in a single field is "not determined". For each work type, the aggregation unit 180 aggregates the quantity of the first work area 400-1 corresponding to the determined work type and the quantity of the second work area 400-2 corresponding to the undetermined work type.

[0055] In step S110 shown in Figure 6, the estimation unit 160 may determine the work period by any method. For example, the estimation unit 160 may determine the work period based on the time the work device 30 entered the field and the time it left the field.

[0056] In step S140 shown in Figure 6, the display unit 250 of the terminal 200 may display the work areas 400 in which work was performed during a predetermined period, for example, from the present time to one month prior. In this case, in step S130, the output unit 190 extracts the work areas 400 in which work was performed during a predetermined period from the work data 300 shown in Figure 4. Specifically, the output unit 190 extracts the work areas 400 in which the work period is included within the predetermined period. Area display information representing the extracted work areas 400 is output to the terminal 200.

For example, some or all of the processing of the work management device 100 may be performed by the terminal 200. Alternatively, some or all of the processing of the terminal 200 may be performed by the work management device 100.

[0058] Furthermore, the work management system 1000 may not include terminal 200 and may display area display information and statistical information on an external terminal not included in the work management system 1000.
