[0001] The present invention relates to a work management method, a work management system, and a work management program, and can be suitably used, for example, in a work management method, a work management system, and a work management program for managing agricultural work. [Background technology]

[0002] In farming, it is important for users to understand and evaluate the production status and productivity of fields they manage or are involved in. However, in highly mechanized fields, even if it is a single field, many working machines are involved, and the types of work performed by these working machines are diverse. Furthermore, the same tractor may be equipped with different working machines and perform different types of work, and planters and harvesters that perform a single type of work may perform the same work over multiple days. In this way, field information can become complex, and it is not easy to understand every nook and cranny.

[0003] In relation to the above, Patent Document 1 (JP Patent Publication 2017-102924 A) discloses an agricultural management system. In this agricultural management system, a database server receives agricultural land information on the farmland where the agricultural crops are harvested and operation information on the harvesting in association with each other and records the information, and displays the information on a terminal display in response to a request from a user.

[0004] Furthermore, Patent Document 2 (Japanese Patent No. 6302391) discloses a remote server. This remote server receives and manages information indicating the status of each agricultural machine from various agricultural machines. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2017-102924 A [Patent Document 2] Patent No. 6302391 Summary of the Invention [Problem to be solved by the invention]

[0030] A work management method according to an embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of a configuration of a work management program according to an embodiment. Hereinafter, an example of the operation of the work management system 1 realized by the work management device 5 executing the work management program in an embodiment will be described.

[0031] When the work management device 5 according to one embodiment is started, the arithmetic device 51 of the work management device 5 executes a work management program, and the work management method starts. When the work management method according to one embodiment starts, step S1 is executed.

[0032] In step S1, the input unit 511 of the calculation device 51 of the work management device 5 prepares area information. The area information represents operation information, work area information, and work type information in association with each other.

[0033] The operation information will now be described. The operation information includes positioning information obtained by measuring multiple positions that the work machine passed while working in the field 9, and machine attribute information that represents the machine attributes of the work machine. The operation information may be transmitted from an on-board terminal 3 mounted on the work vehicle 2 and received by the work management device 5.

[0034] The positioning information will now be described. The positioning information is obtained by measuring multiple positions passed by the on-board terminal 3 mounted on the work vehicle 2 during work. The positioning information includes, for example, the latitude and longitude of the position where the measurement was performed, and the time when the measurement was performed.

[0035] The machine attribute information and the machine attributes represented by the machine attribute information will be described. Machine attributes are attributes that classify work machines according to the work that the work machines perform. Machine attributes include, for example, tractors, transplanters, pesticide sprayers, harvesters, and the like. Note that when it is known that a tractor performs only a specific work, for example, when a certain tractor is dedicated to the work of transplanting or spraying pesticides, the machine attribute of the tractor may be a transplanter or a pesticide sprayer according to the type of machine attached to the tractor. Information that represents machine attributes so that the work management device 5 can handle them is called machine attribute information.

[0036] The work type and work type information will be described. The work type is the type of work performed to grow crops. The work types include, for example, subsoil breaking, plowing, land leveling, transplanting, top dressing, inter-cultivation weeding, pest control, and harvesting. Information that represents the work type so that it can be handled by the work management device 5 is called work type information. The work type information may be acquired by the calculation unit 512 of the arithmetic device 51 of the work management device 5 by estimation based on the machine attribute information.

[0037] The working area and working area information will now be described. The area of ​​the field 9 where the work machine has performed work is called the working area. Information that represents the working area so that the work management device 5 can handle it is called the working area information. The working area information may be acquired by the calculation unit 512 of the arithmetic device 51 of the work management device 5 estimating it based on the positioning information and the working width of the work machine. Here, the working width refers to the width of the area where the work machine performed work on the field 9 while moving. The working area information also includes the date and time when the work was performed, the machine attribute information of the machine, and the work type of the work performed.

[0038] After step S1, step S2 is executed. In step S2, the output unit 515 of the arithmetic device 51 of the work management device 5 and the output unit 613 of the arithmetic device 61 of the external terminal 6 display the work area 91 based on the default conditions. More specifically, first, the output unit 515 of the work management device 5 outputs work area information representing a work area that meets the default conditions and transmits it to the external terminal 6, and then the output unit 613 of the external terminal 6 displays the work area 91 represented by the received work area information. Here, first, how the work area 91 is displayed will be described with reference to FIG. 5. Note that a method for extracting the displayed work area 91 based on the default conditions will be described later.

[0039] 5, the touch panel device as the output device 642 outputs information indicating a work area 91 extracted based on predetermined conditions from among a plurality of farm fields 9 by displaying it on a map. At this time, the touch panel device displays the position and shape of the work area 91 on the map under the control of an output unit 613 realized by the arithmetic device 61 of the external terminal 6 executing a display operation program. The output unit 613 may control the touch panel device to further display a mark 92 indicating a representative position of the work area 91.

[0040] After step S2, step S3 is executed. In step S3, the input unit 511 of the work management device 5 determines whether or not the user has input an extraction condition for the work area 91. More specifically, when the user operates the touch panel device serving as the input device 641 of the external terminal 6 to perform an input for setting or changing the extraction condition for the work area 91, information representing this input is transmitted from the output unit 613 of the external terminal 6 to the input unit 511 of the work management device 5. The input unit 511 of the work management device 5 waits by repeating step S3 while the information representing this input is not received (No), and proceeds to step S4 when the information representing this input is received (Yes).

[0041] An example of a method in which a user operates a touch panel device to input extraction conditions for the work area 91 will be described. In addition to the work area 91 displayed on a map, the touch panel device serving as the output device 642 of the external terminal 6 may display condition setting windows 70, 80 for inputting extraction conditions. The user may operate the touch panel to set or change extraction conditions by appropriately operating input frames 71, 72, 73 and switches 81, 82, 83, 84, 85 provided in the condition setting windows 70, 80.

[0042] 5, the user may set conditions for extracting the work area 91 by inputting a desired character string, a desired period, and a desired work type into input frames 71, 72, and 73 included in the condition setting window 70. Also, by operating switches 81, 82, 83, 84, and 85 included in the condition setting window 80, the user may switch between displaying or not displaying registered fields, displaying or not displaying the work area 91 and the mark 92, displaying or not displaying a work area whose machine attribute is a harvester, displaying or not displaying a work area whose machine attribute is a truck, displaying or not displaying a work area whose machine attribute is a tractor, and displaying or not displaying a work area whose machine attribute is a transplanter, respectively.

[0043] In step S4, the extraction unit 514 of the calculation device 51 of the work management device 5 extracts the work area 91 based on the extraction conditions input in step S3. Here, the extraction unit 514 refers to the area information to extract work type information that satisfies the extraction conditions input in step S3, and extracts work area information associated with the extracted work type information as extracted area information. Here, if there is a one-to-one correspondence between the work type selected as the extraction condition and the machine attribute corresponding to the selected work type, the work area information associated with the machine attribute information representing the machine attribute may be extracted as extracted area information.

[0044] After step S4, step S5 is executed. In step S5, the output unit 515 of the calculation device 51 of the work management device 5 and the output unit 613 of the calculation device 61 of the external terminal 6 display the work area 91 based on the extraction condition. More specifically, first, the output unit 515 of the work management device 5 outputs work area information representing the work area that meets the extraction condition and transmits it to the external terminal 6, and then the output unit 613 of the external terminal 6 displays the work area 91 represented by the received work area information.

[0045] With reference to FIG. 6, an example of the display of the work area 91 extracted based on the extraction conditions input in step S3 will be described. In the example of FIG. 6, the work area 91 in which a work machine having a machine attribute with the switch 83 in an on state performed the work type entered in the input frame 73 during the period entered in the input frame 72 is displayed together with a mark 92. More specifically, the work area 91 in which a work machine having a machine attribute of a harvester corresponding to the switch 83 performed the work of "harvesting", which is the work type corresponding to the input frame 73, during the period from May 1, 2021 to May 7, 2021 entered in the input frame 72 is displayed together with a mark 92. This display is obtained as a result of the user's input into the input frame 72, the input frame 73, and the switch 83 in step S3.

[0046] After step S5, the process may return to step S3 and wait until new extraction conditions are input.

[0047] As described above, in the processes of steps S3 to S5, the user is required to input appropriate extraction conditions in order to display the desired work area 91. The more fields 9 the user manages, the more complicated the input of extraction conditions may become. Therefore, in one embodiment, an attempt is made to estimate the work area 91 desired by the user at the time of step S2 and automatically display it.

[0048] Details of step S2 will be described with reference to Fig. 7. When step S2 is executed after step S1 in Fig. 4, step S201 in Fig. 7 is executed first.

[0049] In step S201, the input unit 511 of the calculation device 51 of the work management device 5 prepares cultivation calendar information representing a cultivation calendar. The cultivation calendar information is stored in the cultivation calendar information storage unit 524 of the storage device 52 of the work management device 5, as shown in Fig. 2. The cultivation calendar information may be read from the recording medium 520, or may be obtained from the outside via the communication device 53.

[0050] FIG. 8 is a table showing an example of the contents of a cultivation calendar according to an embodiment. A plurality of periods are arranged in order in the horizontal direction of the table in FIG. 8. Here, "B" represents the beginning of each month, "M" represents the middle of each month, and "E" represents the end of each month. In addition, work types and work names representing the work types are arranged in the vertical direction of the table in FIG. 8. In a cell where a period and a work type intersect, a check is entered if the work type is scheduled to be performed in that period, and conversely, no check is entered if the work type is not scheduled. Note that the work name is a name used uniquely by a producer or a production area, and may be the same as the work type, or a name different from the work type may be used as long as it is linked to the work type. As an example, the work name "planting" may be used corresponding to the work type "transplanting".

[0051] The cultivation calendar may be filled in or changed by the user. As an example, with the table shown in FIG. 8 displayed on a touch panel device serving as the output device 642 of the external terminal 6, the user can check or delete a cell where a period and a task type intersect by operating the touch panel device serving as the input device 641 of the external terminal 6. The user can also add or delete a task type row by operating the "ADD" button or "DELETE" button. Furthermore, the user can change the task type of that row by operating the task type pull-down menu.

[0052] After step S201, step S202 is executed. In step S202, a login by a user occurs, and the input unit 511 of the calculation device 51 of the work management device 5 acquires the login time. This login may occur when the user starts up the external terminal 6 and the external terminal 6 starts communication with the work management device 5.

[0053] After step S202, step S203 is executed. In step S203, the extraction unit 514 of the calculation device 51 of the work management device 5 reads out the content corresponding to the login time from the cultivation calendar. Here, the extraction unit 514 extracts, from the cultivation calendar information, the work type scheduled for the period including the login time at which the user logged in. The extracted work type is called the extracted work type. In the example shown in FIG. 8, when the login time is included in early May 2021, data for period 101 is read out from the cultivation calendar information.

[0054] After step S203, step S204 is executed. In step S204, the determination unit 513 of the calculation device 51 of the work management device 5 determines whether or not there is one work type that corresponds to the content read out in step S104. If there is one work type that corresponds (Yes), step S204 is followed by step S205. Conversely, if there is not one work type that corresponds (No), step S204 is followed by step S207. In the example shown in FIG. 8, the work type included in the read data for period 101 is one type, "top dressing," so in this case step S204 is followed by step S205.

[0055] In step S205, the extraction unit 514 of the calculation device 51 of the task management device 5 extracts a task area in which the task type corresponding to the content read in step S203 is performed. More specifically, task area information that represents the task area associated with the task type of interest is extracted. The extracted task area information is called extracted area information.

[0056] After step S205, step S206 is executed. In step S206, the output device 642 of the external terminal 6 displays the work area represented by the extraction area information extracted in step S205. More specifically, the output unit 515 of the work management device 5 controls the communication device 53 to transmit the extraction area information to the external terminal 6, and the output unit 613 of the calculation device 61 of the external terminal 6 controls the output device 642 to display the work area 91 represented by the extraction area information.

[0057] As an example, in step S206, the extracted work area 91 may be displayed as shown in Fig. 9. Fig. 9 is a diagram showing an example of a display according to an embodiment. At this time, a period including the login time may be displayed in input frame 72 of condition setting window 70. Furthermore, the extracted work type may be displayed in input frame 73 of condition setting window 70.

[0058] After step S206, the process proceeds to step S3 in FIG.

[0059] In step S207, the calculation unit 512 of the arithmetic device 51 of the work management device 5 counts up the total number of work areas for each work type that exists within a predetermined period. More specifically, the calculation unit 512 calculates the total number of pieces of extracted area information associated with each of the multiple work types determined in step S204 to be more than one type. FIG. 10 is a table showing an example of the contents of a cultivation calendar according to one embodiment. In the example of FIG. 10, the work types included in the read data for the period 102 are three types, "transplanting," "top dressing," and "inter-tillage weeding," so the total number of pieces of extracted area information associated with each of these three types of work types is calculated.

[0060] After step S207, step S208 is executed. In step S208, the extraction unit 514 of the calculation device 51 of the task management device 5 extracts the task area of ​​the task type for which the total number tallied in step S207 is the largest.

[0061] After step S208, step S209 is executed. In step S209, similarly to step S206, the output unit 613 of the external terminal 6 controls the output device 642 to display the registered field 9 and the work area extracted in step S208.

[0062] As an example, in step S209, the registered and scattered fields 9 may be displayed as shown in FIG. 11A, and the extracted work areas may be displayed as shown in FIG. 11B. FIG. 11A is a diagram showing an example of a display according to an embodiment. FIG. 11B is a diagram showing an enlarged view of a part 93 of FIG. 11A. At this time, a condition setting window 70 may be displayed in FIG. 11A together with the fields 9, and a period including the login time may be displayed in an input frame 72 of the condition setting window 70. In addition, all of the extracted work types may be displayed in an input frame 73 of the condition setting window 70. In the example of FIG. 11A, the three types of work types, "transplanting", "top dressing", and "intertillage weeding", read out in FIG. 10, are displayed in the input frame 73. As an example, when there are multiple extracted work types, the order in which these multiple work types are displayed in the input frame 73 may be the order of the number of total work areas of the work type. In the example of FIG. 11A, "transplanting", which has the largest number of total work areas, is displayed at the top of the input frame 73 and is highlighted in bold.

[0063] In the example of FIG. 11B, fields 9A, 9B, 9C, 9D, 9E, and 9F are displayed in a part 93 of FIG. 11A. Also, in the example of FIG. 11B, it is shown that the work area 9A1 of "transplanting", which has the largest total number of corresponding work areas, exists inside the field 9A. Similarly, in the example of FIG. 11B, it is also shown that the work areas 9D1 and 9D2 of "transplanting" exist inside the field 9D. In this case, the work areas 9B1 and 9B2 of "top dressing" displayed in the input frame 73 of FIG. 11A may or may not be displayed as existing inside the field 9B, but if displayed, it is preferable to display the work areas 9A1, 9D1, and 9D2 of "transplanting" more emphatically. Similarly, for the "inter-tillage weeding" work area 9C1 displayed in the input frame 73 in Figure 11A, it may or may not be displayed that it is inside the field 9C, but if it is displayed, the "transplanting" work areas 9A1, 9D1, and 9D2 are displayed with more emphasis. However, in either case, it is preferable to always display the frame lines representing the fields 9A, 9B, 9C, 9D, 9E, and 9F.

[0064] FIG. 11C is a diagram showing FIG. 11B in another state. This state is a state transitioned to by the user selecting one of the work types displayed in the input frame 73 shown in FIG. 11A by operating the external terminal 6, etc. The example of FIG. 11C shows a state in which "top dressing" is selected among the work types displayed in the input frame 73 shown in FIG. 11A. At this time, "top dressing" is displayed in bold in the input frame 73, and FIG. 11C shows that the work areas 9B1 and 9B2 of "top dressing" are present inside the field 9B. At this time, the remaining work areas 9A1, 9D1, and 9D2 of "transplanting" and the work area 9C1 of "inter-tillage weeding" may or may not be displayed, but if they are displayed, the work areas 9B1 and 9B2 of "top dressing" selected in the input frame 73 are displayed with greater emphasis. However, in either case, it is preferable to display the frame lines representing the fields 9A, 9B, 9C, 9D, 9E, and 9F at all times.

[0065] After step S209, the process proceeds to step S3 in FIG.

[0066] (Modification) A modified example of the work management method according to an embodiment will be described with reference to Fig. 12. The work management method according to this modified example is obtained by replacing step S4 shown in Fig. 4 with the flowchart shown in Fig. 12. In this modified example, when step S4 shown in Fig. 4 starts, step S401 shown in Fig. 12 starts.

[0067] In step S401, the determination unit 513 of the work management device 5 determines whether the extraction conditions include a period and do not include a work type and a machine attribute. If the result of the determination is true (TRUE), the process proceeds to step S402. On the other hand, if the result of the determination is false (FALSE), the process proceeds to step S404.

[0068] In step S402, the calculation unit 512 of the work management device 5 counts the total number of work areas for each work type that exists within the target period that meets the extraction conditions. At this time, the work area for the work type with the largest total number is stored so that it can be distinguished from the work areas for the other work types. As an example, in the cultivation calendar shown in FIG. 13, the period 103 from early April 2021 to late May 2021 is included in the extraction conditions, and the work types that exist in this period 103 are "transplanting," "top dressing," and "inter-tillage weeding."

[0069] After step S402, step S403 is executed. In step S403, the extraction unit 514 of the work management device 5 extracts work areas of all work types that exist within the target period that meets the extraction conditions. As an example, in the example shown in FIG. 13, the work areas of "transplanting", "top dressing", and "inter-tillage weeding" are extracted.

[0070] After step S403, the process proceeds to step S5 in FIG. 4. In step S5, the registered scattered fields 9 are displayed as in FIG. 14A, and the work areas extracted in step S403 are displayed as in FIG. 14B. FIG. 14A is a diagram showing an example of a display according to one embodiment. FIG. 14B is a diagram showing an enlarged view of a portion 93 in FIG. 14A. At this time, the work area of ​​the work type with the largest total number tallied in step S402 is highlighted so as to be distinguished from the work areas of the other work types. As an example, the display example shown in FIG. 14B displays the work areas of "transplanting," "top dressing," and "intertillage weeding" extracted in step 403. More specifically, it shows that the work areas 9A1, 9D1, and 9D2 of "transplanting" are located inside the fields 9A and 9D, the work areas 9B1 and 9B2 of "top dressing" are located inside the field 9B, and the work area 9C1 of "inter-tillage weeding" is located inside the field 9C. Furthermore, among these work areas, the work areas 9A1, 9D1, and 9D2 of "transplanting", which has the largest total number, are highlighted so as to be distinguishable from the other work areas 9B1, 9B2, and 9C1. In the example of FIG. 14B, the work areas are highlighted with a thick line, but the present disclosure is not limited to this example, and other highlighting may be performed using a different color or a different line type.

[0071] In the state of FIG. 14B, the display for identifying the work type corresponding to each work area may be omitted. On the other hand, as a result of the user performing an operation to select the display of the work area, the work type of the work area may be displayed by characters or the like. An example of the display in such a state is shown in FIG. 14C. In the example of FIG. 14C, when the user selects the work area 9B1 or 9B2 of "top dressing" by touching the touch panel or the like, the characters "top dressing" are displayed in these work areas 9B1 and 9B2. At this time, the work areas 9A1, 9D1, and 9D2 of "transplanting" that were displayed until then and the work area 9C1 of "inter-tillage weeding" may remain displayed or may not be displayed, but if displayed, it is preferable to display the selected work areas 9B1 and 9B2 of "top dressing" in an emphasized manner so that they can be distinguished.

[0072] When performing these processes, the input box 73 may remain blank unless the user operates the input box 73. Conversely, the user may operate the input box 73 to search for a work area of ​​the specified work type. As a result, work areas that match the search conditions may be selectively displayed.

[0073] In step S404, the extraction unit 514 of the task management device 5 extracts the task area of ​​the extracted task type. Here, the task area of ​​the extracted task type may be the task area of ​​all task types that meet the extraction condition.

[0074] After step S404, the process proceeds to step S5 in Fig. 4. In step S5, all the work areas extracted in step S404 are displayed.

[0075] As described above, according to one embodiment, the user operates the external terminal 6 to log in, and before the user sets the conditions for extracting the work area 91, the information required by the user is predicted and automatically displayed. As a result, the information required by the user can be output efficiently. After that, the user can also output other information desired by the user by appropriately setting the extraction conditions.

[0076] Although the invention made by the inventor has been specifically described based on the embodiment, the present invention is not limited to the embodiment, and it goes without saying that various modifications can be made without departing from the gist of the invention. Furthermore, the respective features described in the embodiment can be freely combined within the scope of technical compatibility. [Explanation of symbols]
