Description

[Technical field]

[0001] The present invention relates to a work management method, a work management system, and a work management program. [Background technology]

[0002] Even if the same work, for example harvesting, is being performed in a farm field, the next work to be performed may differ depending on the content of the work that has been performed in the farm field.

[0003] For example, Patent Document 1 discloses a technique for producing silage from straw after harvesting grains, such as rice. This technique produces silage by leaving the straw from which the rice grains have been separated for a short period of time in a farm field to absorb moisture and then subjecting it to anaerobic fermentation.

[0004] Patent Document 2 also describes a method of supplementing the nitrogen source in the field by plowing in straw after harvesting grains. In this case, as described in Patent Document 2, the straw is chopped by a combine and discharged into the field. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2010-081933 A [Patent Document 2] JP 2012-147727 A Summary of the Invention [Problem to be solved by the invention]

[0006] In this way, even after the same grains are harvested, the next work to be done may be different. In particular, when there are many fields, it is necessary to check the next work to be done for each field while preparing for the next work. Even in the case of a single field, if preparation for the next work is done in a location away from the field, preparation for a different work from the planned work may be done.

[0007] In view of the above circumstances, one of the objects of the present disclosure is to support a user by notifying the user of information regarding a next task based on operation information of a working device performing work in a farm field. Other objects can be understood from the following description and the explanation of the embodiment. [Means for solving the problem]

[0008] The means for solving the problems will be described below using the numbers and symbols used in the description of the embodiment of the invention. These numbers and symbols are added in parentheses for reference purposes to show an example of the correspondence between the description of the claims and the description of the embodiment of the invention. Therefore, the description in parentheses should not be interpreted as limiting the scope of the claims.

[0009] To achieve the above object, a work management method according to one embodiment includes determining a second work type of a second work performed after the first work by the first work implement (30) based on a comparison between operation information indicating a state of the first work implement (30) performing the first work in a farm field (400) and pre-stored conditions. The work management method also includes outputting second work information related to the second work.

[0010] To achieve the above object, a work management system (1000) according to one embodiment includes a next work determination unit (170) and a next work output unit (180). The next work determination unit (170) determines a second work type of a second work to be performed after the first work by the first work implement (30) based on a comparison between operation information indicating a state of the first work implement (30) performing a first work in a field (400) and pre-stored conditions. The next work output unit (180) outputs second work information related to the second work.

[0011] To achieve the above object, a work management program (320) according to one embodiment causes the arithmetic device (120, 220) to determine a second work type of a second work performed after a first work by the first work implement (30), based on a comparison between operation information indicating a state of the first work implement (30) performing a first work in a field (400) and pre-stored conditions. The work management program (320) also causes the arithmetic device (120, 220) to output second work information related to the second work. Effect of the Invention

[0012] According to the above aspect, the user can easily check the next work to be performed in the field. [Brief description of the drawings]

[0014] (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 Fig. 1, the work management system 1000 includes a work management device 100 and one or more terminals 200, for example, a first terminal 200-1 and a second terminal 200-2. The work management device 100 is communicatively connected to the terminal 200 and one or more work devices 30 via a network 20, for example, the Internet.

[0015] The working device 30 includes, for example, a harvester that harvests crops, and moves within a farm field to perform work. The working device 30 may be a vehicle that pulls a work machine that performs work, for example, a tractor. The working device 30 may be a vehicle that performs seedling transplant work, for example, a rice transplanter or transplanter. The working device 30 may be a vehicle that sprays materials, for example, a sprayer (pesticide sprayer) or a fertilizer applicator.

[0016] The working device 30 acquires operation information indicating the state of the working device 30 while moving within the farm field 400 and performing work. The acquired operation information is output to the work management device 100. The operation information indicates the state of the working device 30 at each time, and indicates, for example, the speed, steering angle, engine speed, and ON / OFF status of various clutches of the working device 30. Furthermore, when the working device 30 is a vehicle that tows a work machine, the operation information may include information such as the PTO (power take-off) speed when transmitting power to the work machine, and the hitch height and lift arm angle indicating the attitude of the work machine. Furthermore, when the working device 30 is a harvester that harvests grain, the operation information may include information indicating whether or not the stalks (straw) after the rice husks are separated are cut depending on the ON / OFF status of various clutches.

[0017] The work device 30 also includes a positioning device, for example a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position at each time the work device 30 moves. The acquired position information is included in the operation information.

[0018] The work management apparatus 100 determines a next work type that indicates the work type of the work to be performed next in the field 400, based on the operation information acquired from the work apparatus 30. Here, the work type indicates the type of work, such as harvesting, plowing, turning over straw, sowing, etc. For example, when the work apparatus 30 is cutting and discharging straw, the work management apparatus 100 determines that the next work type is "plowing over". Also, when the work apparatus 30 is discharging straw without cutting it, the work management apparatus 100 determines that the next work type is "turning over straw". The work management apparatus 100 outputs next work information that indicates information related to the next work to the terminal 200.

[0019] The terminal 200 notifies the user of the next work information acquired from the work management device 100. For example, the first terminal 200-1 notifies the user who manages the work in the field 400, such as the manager or the owner of the field 400, of the next work information. This allows the manager to grasp the status of the work in the field 400. In addition, the second terminal 200-2 notifies the worker of the next work device 40 to be used for the next work of the next work information. The worker can prepare the next work device 40 based on the next work information. For example, the worker can confirm the work machine to be connected to the next work device 40, for example, a tractor, according to the information on the next work that indicates the work to be performed next. For example, when the next work is "straw turning", the worker connects a "tedder rake" to the tractor of the next work device 40. In addition, when the next work is "plowing", the worker connects a "rotary cultivator" to the tractor of the next work device 40.

[0020] In this way, the work management system 1000 supports the user in working in the field 400 by notifying the user of next work information related to the next work in the field 400. By checking the next work information related to the next work, the user, for example, a worker, can reduce mistakes in work in the field 400. In addition, because the work management system 1000 outputs information related to the next work based on the operation information acquired from the work device 30, the user, for example, a manager, can grasp the work status without waiting for a report from the worker.

[0021] The operation information may further include the amount of work performed by the working device 30. For example, when the working device 30 is a vehicle that harvests, the operation information may include information that indicates the harvest amount. Furthermore, when the working device 30 is a vehicle that transplants or sprays materials, the operation information may include information such as the planting amount and the spraying amount (nozzle opening degree and shutter opening degree).

[0022] (Work management system configuration) The configuration of a work management apparatus 100 included in the work management system 1000 shown in FIG. 1 will be described. As shown in FIG. 2, the work management apparatus 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management apparatus 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 outputs a result of the calculation device 120 executing the processing. The input / output device 110 includes various input devices and output devices, 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.

[0023] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 130 transfers operation information acquired from the maintenance device 30 to the arithmetic device 120. Also, the communication device 130 transfers a signal generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, for example, a network interface card (NIC) and a universal serial bus (USB).

[0024] The storage device 140 stores various data for determining the work type of the next work to be performed in the field 400, such as work data 300, field data 310, and a work management program 320. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 320. The work management program 320 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.

[0025] The work data 300 indicates conditions for determining the work type of the next work according to the work type of the work being performed in the field 400 and the type of work implement 30 being used. For example, as shown in FIG. 3, the work data 300 stores information that associates the work type, the type of work implement 30, conditions, and the next work type. The work type indicates the type of work being performed in the field 400, such as harvesting, straw turning, plowing, straw compression and packaging, etc. The type of work implement 30 indicates the type of work implement 30 being used for the work being performed in the field 400. The conditions are used to determine the work type of the next work to be performed. The next work type indicates the type of work to be performed next. When a condition indicated in the work data 300 is satisfied, the work of the next work type corresponding to that condition will be performed next.

[0026] For example, when "harvesting" is being performed by a "combine" in the field 400, if the condition that the ratio of work in which the combine cuts straw is equal to or greater than a threshold is satisfied, the work management device 100 determines that "plowing" will be performed next. Also, when "harvesting" is being performed by a "combine" in the field 400, if the condition that the ratio of work in which the combine cuts straw is less than a threshold is satisfied, the work management device 100 determines that "straw turning" will be performed next. Also, there are cases where the work type of the next work is determined without any conditions for determination. In the example shown in FIG. 3, when "straw turning" is being performed by a "tedder / rake" in the field 400, the work management device 100 unconditionally determines that "straw compression / packing" will be performed next.

[0027] The field data 310 shown in FIG. 4 stores information that associates the type of work performed in each field 400, the worker performing the work, and the type of work implement 30 used for the work. For example, the field data 310 stores information that associates the field name, field area, work type, worker, and type of work implement used. The field name represents the field 400 where the work is performed. The field area represents the area of ​​the field 400, for example, the position and shape. The work type represents the type of work performed in the field 400. The worker represents the worker performing the corresponding work in the field 400. The type of work implement used represents the type of work implement 30 used when the corresponding worker performs the corresponding work.

[0028] The example shown in Figure 4 indicates that "harvesting" in "field A" is performed by "worker A" using a "combine harvester." It also indicates that "straw turning" in "field A" is performed by "worker B" using a "tedder and rake." It also indicates that "harvesting" in "field B" is performed by "worker E" using a "combine harvester."

[0029] 2 executes the work management program 320 and is used for various data processing for determining the work type of the next work to be performed in the field 400. For example, the calculation device 120 includes a central processing unit (CPU) and the like.

[0030] The arithmetic device 120 reads and executes the work management program 320, thereby implementing a data storage unit 150, a work status determination unit 160, a next work determination unit 170, and a next work output unit 180, as shown in FIG. 5. The data storage unit 150 stores work data 300 and farm field data 310. The work status determination unit 160 determines the work status being performed in the farm field 400 based on operation information acquired from the work device 30. For example, the work status determination unit 160 identifies the farm field 400 where work is being performed by the work device 30 and determines the progress of the work. The next work determination unit 170 determines the next work type of the next work to be performed next in the farm field 400 based on operation information acquired from the work device 30. The next work output unit 180 outputs next work information related to the next work to the terminal 200.

[0031] Next, the configuration of the terminal 200 will be described. As shown in FIG. 6, the terminal 200 includes an input / output device 210, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

[0032] 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 device 220. Also, the communication device 230 transfers a signal generated by the arithmetic device 220 to the work management device 100. The communication device 230 includes various interfaces, such as a transceiver used for wireless communication in a wireless LAN (Local Area Network) or a cellular network, a NIC (Network Interface Card), a USB (Universal Serial Bus), and the like.

[0033] The storage device 240 stores various data for notifying the user of the next task information, for example, a notification program 330. The storage device 240 is used as a non-transitory tangible storage medium for storing the notification program 330. The notification program 330 may be provided as a computer program product recorded in a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

[0034] The arithmetic device 220 reads and executes the notification program 330, thereby working together with the input / output device 210 to realize the notification unit 250 as shown in Fig. 5. The notification unit 250 acquires next task information related to the next task from the task management device 100, and notifies the user of the acquired next task information. For example, the notification unit 250 displays the next task information on the input / output device 210.

[0035] (Operation of the work management device) When the arithmetic device 120 of the work management apparatus 100 receives operation information from the work apparatus 30, it reads and executes the work management program 320. By executing the work management program 320, the arithmetic device 120 executes the process shown in Fig. 7, which is a work management method.

[0036] In step S110, the work status determination unit 160 realized by the calculation device 120 identifies the field 400 where work is being performed, based on the operation information acquired from the work device 30. For example, the work status determination unit 160 identifies the field 400 where work is being performed by the work device 30, based on the position information of the work device 30 included in the operation information. The work status determination unit 160 searches the field data 310 for a field 400 having a field area including the position indicated in the position information of the work device 30. The work status determination unit 160 identifies the searched field 400 as the field 400 where work is being performed.

[0037] In step S120, the work status determination unit 160 determines the progress amount, for example the progress rate, of the work in the field 400 based on the operation information of the working device 30. For example, the work status determination unit 160 determines the ratio of the area where the working device 30 has performed the work to the area of ​​the field 400 as the progress amount. For example, the work status determination unit 160 determines a convex hull including the positioning positions indicated in the position information of the working device 30 as the completed area where the working device 30 has performed the work. The convex hull represents the smallest area including all the positioning positions. The completed area may also represent an area obtained by expanding the outline of the convex hull outward by the working width of the working device 30. The work status determination unit 160 determines the area of ​​the completed area as the area where the working device 30 has performed the work. The work status determination unit 160 determines the progress amount by dividing the area of ​​the field 400 where the work is being performed by the area of ​​the completed area.

[0038] Here, the working width of the working implement 30 is registered in advance by the working implement 30. For example, the working width represents the distance in the width direction of the working implement 30 from the position of a positioning device provided on the working implement 30 to the edge of the area in which the working implement 30 works. The working width represents the distance in the width direction of the working implement 30 from the position of a positioning device provided on the working implement 30 to the edge of the area in which the working implement works when a tractor pulls the agricultural machine.

[0039] In step S130, the work status determination unit 160 compares the determined progress amount with a threshold value. When the progress amount is less than the threshold value, the process returns to step S120, and the progress amount is determined based on newly received operation information. When the progress amount is equal to or greater than the threshold value, the process proceeds to step S140. For example, the threshold value is set so that it can be determined that the work by the work implement 30 in the field 400 will soon be completed. For example, the threshold value may be set to 80% or more, 90% or more, or 100%.

[0040] In step S140, the next work determination unit 170 compares the operation information acquired from the work device 30 with the conditions stored in the work data 300. For example, first, the next work determination unit 170 acquires, from the work data 300, the work type of the work being performed in the field 400 and the conditions corresponding to the work device 30 performing the work. The work type of the work being performed in the field 400 and the type of work device 30 performing the work are registered in advance in the work management apparatus 100. In the example shown in FIG. 3, when "harvesting" is being performed by a "combine" in the field 400, the next work determination unit 170 acquires, as the corresponding conditions, that "the proportion of work in which straw is cut is equal to or greater than a threshold value" and that "the proportion of work in which straw is cut is less than a threshold value."

[0041] Next, the next work determination unit 170 determines which of the acquired conditions is satisfied by the operation information. For example, when "harvesting" is being performed by a "combine" in the field 400, the next work determination unit 170 determines the proportion of work in the field 400 in which the work device 30 (combine) cut straw. For example, the next work determination unit 170 determines the proportion of the cutting work area in which the work device 30 cut straw to the area of ​​the field 400 as the proportion of the straw cut by the work device 30.

[0042] The cutting work area may be determined, for example, based on the position where the working device 30 cut and discharged the straw. The next work determination unit 170 extracts cutting work position information corresponding to the time when the operation information indicating that the straw was being cut was measured from the position information included in the operation information.

[0043] 8, for example, it is assumed that the positioning device of the working device 30 measures the position of the working device 30 in the order of the first positioned position 500-1 to the ninth positioned position 500-9. At this time, it is assumed that the working device 30 cuts straw when it moves from the first positioned position 500-1 to the third positioned position 500-3 and when it moves from the seventh positioned position 500-7 to the ninth positioned position 500-9. It is also assumed that the working device 30 does not cut straw when it moves from the fourth positioned position 500-4 to the sixth positioned position 500-6. In this case, the operation information corresponding to the first located position 500-1, the second located position 500-2, the third located position 500-3, the seventh located position 500-7, the eighth located position 500-8, and the ninth located position 500-9 indicates that the working device 30 was cutting straw. Also, the operation information corresponding to the fourth located position 500-4, the fifth located position 500-5, and the sixth located position 500-6 indicates that the working device 30 is not cutting straw. Therefore, the next work determination unit 170 extracts cutting work position information indicating the cutting work position 550 indicating the position when the straw was being cut from the position information indicating the located position 500.

[0044] The next operation determination unit 170 determines the area of ​​a convex hull including the cutting operation position 550 of the extracted cutting operation position information as the cutting operation area. The cutting operation area may represent the area of ​​a region obtained by expanding the outline of the convex hull outward by the operation width of the working device 30.

[0045] The next task determination unit 170 divides the cutting task area by the area of ​​the field 400 where the task is being performed by the task device 30 to determine the task proportion of cutting straw among the tasks in the field 400. The next task determination unit 170 compares the determined task proportion with a threshold value stored in the task data 300 to determine the conditions satisfied by the operation information.

[0046] In step S150 shown in Fig. 7, the next work determination unit 170 determines the next work type corresponding to the condition satisfied by the operation information in the work data 300 as the work type of the next work. As shown in Fig. 3, in a situation where "harvesting" is being performed by a "combine" in a farm field 400, when the work ratio of the work of cutting straw is equal to or greater than a threshold value, the next work determination unit 170 determines that the work to be performed next is "plowing in". In addition, when the work ratio of the work of cutting straw is less than the threshold value, the next work determination unit 170 determines that the work to be performed next is "reversing straw".

[0047] In step S160 shown in Fig. 7, the next work output unit 180 outputs next work information related to the determined next work to the terminal 200. The next work output unit 180 determines the worker who will perform the next work and the type of next work device 40 to be used in the next work based on the determined next work type of the next work and the field data 310. The next work output unit 180 outputs next work information related to the next work, such as the field 400 where the work will be performed and the type of next work device 40 to be used in the next work, to the terminal 200 of the worker who will perform the next work. The next work output unit 180 may also output next work information to the terminal 200 of another user, such as the work manager or the owner of the field 400.

[0048] For example, when the field 400 where work is being performed is "Field A" and the next work type indicates "straw inversion" based on the field data 310 shown in Fig. 4, the next work output unit 180 determines that the worker performing the next work is "Worker B" and that the type of next work device 40 to be used for the next work is a "tedder / rake". The next work output unit 180 outputs information about the next work, for example information indicating that "straw inversion" will be performed using a "tedder / rake" in "Field A", to the terminal 200 of "Worker B".

[0049] When the field 400 in which work is being performed is "Field A" and the next work type indicates "plowing in", the next work output section 180 determines that the worker performing the next work is "Worker D" and that the type of next work implement 40 to be used for the next work is a "rotary tiller". The next work output section 180 outputs information about the next work to the terminal 200 of "Worker D", for example information indicating that "plowing in" will be performed in "Field A" using a "rotary tiller".

[0050] In step S170 shown in FIG. 7, the notification unit 250 of the terminal 200 notifies the user of the acquired next work information. For example, the notification unit 250 displays on the input / output device 210 the next work information indicating the field 400 in which the next work is to be performed, the type of the next work to be performed in the field 400, and the type of the next work device 40 to be used in the next work. For example, the notification unit 250 displays an image showing the area of ​​the field 400 in which the next work is to be performed on a map. The notification unit 250 may also notify the worker of the next work information by voice. The user, for example, the worker performing the next work, checks the next work information, prepares the next work device 40, and moves to the field 400 in which the next work is to be performed. In this way, the user can check the field 400 in which the work is to be performed and the work device 30 to be used in the work and make preparations.

[0051] Furthermore, in addition to the next task information, the notification unit 250 may notify a user, for example, a work manager or an owner of the field 400, of the progress of the work being performed in the field 400 as the work status. By checking the progress of the work, the user can grasp the work status in the field 400. In this case, the next task output unit 180 of the work management apparatus 100 may output information indicating the progress of the work to the terminal 200, in addition to the next task information.

[0052] When a user who has been notified of the next work information, for example a worker who is to perform the next work, uses the next work device 40 to perform the work, the next work device 40 acquires operation information indicating the state of the next work device 40 and outputs the acquired operation information to the work management apparatus 100. When the arithmetic device 120 of the work management apparatus 100 receives the operation information from the next work device 40, it executes the process shown in FIG. 7. In step S110, the work status determination unit 160 of the work management apparatus 100 specifies the field 400 in which the next work device 40 is performing work, based on the operation information of the next work device 40. Here, the next work device 40 may specify the field 400 in which the previous work was performed as the field 400 in which the work is being performed. Next, in step S120, the work status determination unit 160 determines the progress amount of the work.

[0053] When the determined progress amount is equal to or greater than the threshold, in step S140, the next work determination unit 170 compares the operation information acquired from the next work apparatus 40 with the conditions stored in the work data 300. In addition, in step S150, the next work determination unit 170 determines the next work type corresponding to the condition satisfied by the operation information as the work to be performed next. Here, the next work determination unit 170 may determine the next work determined for the previous work performed in the field 400 as the work being performed by the next work apparatus 40. In addition, the next work determination unit 170 may determine the type of next work apparatus 40 performing work in the field 400 as the type of next work apparatus 40 determined for the previous work performed in the field 400.

[0054] For example, when "harvesting" is performed in the field 400 and the next work determination unit 170 determines that the next work is "straw inversion", the next work determination unit 170 may determine that the next work device 40 is performing "straw inversion". Also, when "harvesting" is performed in the field 400 and the next work output unit 180 determines that a "tedder / rake" is to be used, the next work determination unit 170 may determine that the type of work device used in the field 400 is a "tedder / rake". In this case, the next work determination unit 170 determines that "straw compression / packaging" will be performed next because "straw inversion" is being performed by a "tedder / rake" based on the work data 300 shown in FIG. 3, there is no condition.

[0055] In step S160, the next task output unit 180 outputs next task information relating to the determined next task, for example, "compressing and packing straw", to the terminal 200. In step S170, the notification unit 250 of the terminal 200 notifies the user of the next task information.

[0056] In this manner, the work management system 1000 can repeatedly execute the process shown in FIG. 7 until there is no more work to be performed.

[0057] (Modification) The configuration described in the embodiment is an example, and the configuration can be changed to the extent that the function is not impaired. For example, an example has been shown in which the work type used in the processing of step S140 shown in Fig. 7, specifically, the work type of the work being performed in the farm field 400, is registered in advance in the work management apparatus 100, but this is not limiting, and the work type may be determined by any method. The work type may be estimated by the work status determination unit 160 based on the operation information of the work device 30.

[0058] Also, an example has been shown in which the type of work device 30 used in the processing of step S140, specifically, the type of work device 30 performing work in the field 400, is registered in advance in the work management apparatus 100, but this is not limiting and the type of work device 30 may be determined by any method. For example, the work status determination unit 160 may determine the type of work device 30 based on transmission source information included in the operation information acquired from the work device 30.

[0059] In step S120, the work status determination unit 160 has determined a convex hull including the positioning position represented in the position information of the work device 30 as the completed area where the work has been performed by the work device 30, but the present invention is not limited to this, and the completed area may be determined by any method. For example, the work status determination unit 160 may determine the completed area based on the movement trajectory of the work device 30. For example, the work status determination unit 160 determines a movement trajectory in which the positioning positions represented in the position information are connected by a line, for example, a straight line segment, in the order of the time at which the positions were measured. The work status determination unit 160 determines an area whose distance from the movement trajectory is within the work width of the work device 30 as the completed area.

[0060] Furthermore, in step S120, the work status determination unit 160 may determine the amount of progress by any method. For example, the work status determination unit 160 may determine, as the amount of progress, the ratio of the amount of work performed by the work device 30 to the amount of work performed in the field 400. For example, when the work device 30 sprays pesticide, the work status determination unit 160 may determine, as the amount of progress, the ratio of the amount of pesticide sprayed by the work device 30 to the amount of pesticide sprayed in the field 400.

[0061] In step S140, the next work determination unit 170 determines the area of ​​the convex hull including the cutting work position 550 as the cutting work area where the straw was cut, but the cutting work area may be determined by any method without being limited to this. For example, the next work determination unit 170 may determine the cutting work area based on a cutting movement trajectory that represents the trajectory along which the working device 30 moved while cutting the straw. For example, as shown in FIG. 9, the next work determination unit 170 extracts the cutting work position 550 where the working device 30 cut the straw from the measured positioning positions 500 of the working device 30 based on the operation information. The next work determination unit 170 determines a cutting movement trajectory 560 that connects two adjacent cutting work positions 550 with a line, for example, a straight line segment, in the order of the time when the positioning positions 500 were measured.

[0062] For example, the first positioned position 500-1 and the second positioned position 500-2 are adjacent to each other in the order of time when the positioned positions 500 were measured, so the next task determination unit 170 determines the line segment connecting the first positioned position 500-1 and the second positioned position 500-2 as a part of the first cutting movement trajectory 560-1. Similarly, the next task determination unit 170 determines the line segment connecting the second positioned position 500-2 and the third positioned position 500-3 as a part of the first cutting movement trajectory 560-1. Here, the third positioned position 500-3 and the seventh positioned position 500-7 are not adjacent to each other because they sandwich the fourth positioned position 500-4 to the sixth positioned position 500-6 in between in the order of time when the positioned positions 500 were measured. Since the seventh positioning position 500-7 and the eighth positioning position 500-8 are adjacent to each other, the next task determination unit 170 determines the line segment connecting the seventh positioning position 500-7 and the eighth positioning position 500-8 as part of the second cutting movement trajectory 560-2. Similarly, the next task determination unit 170 determines the line segment connecting the eighth positioning position 500-8 and the ninth positioning position 500-9 as part of the second cutting movement trajectory 560-2. In this manner, the next task determination unit 170 determines the cutting movement trajectory 560.

[0063] The next task determination unit 170 determines the area of ​​the region in which the distance of the determined cutting movement trajectory 560 is within the task width of the task device 30 as the cutting task area.

[0064] 7, the next work determination unit 170 may use any method to determine the work ratio that indicates the ratio of work in which the work device 30 cuts straw to the work in the field 400. For example, when the work device 30 outputs operation information after the work in the field 400 is completed, the next work determination unit 170 may determine the amount of cut straw, for example the weight ratio, to the amount of cut straw, for example the weight, of the harvested straw as the work ratio of the work in which straw is cut.

[0065] 3 shows an example in which the task data 300 stores conditions corresponding to the task type and the task device 30 that performs the task, but is not limited to this. For example, the task data 300 may store conditions corresponding to only the task type. Furthermore, the task data 300 may store conditions corresponding to the task device 30.

[0066] Further, the farm field data 310 shown in FIG. 4 stores information associating the type of work performed in the farm field 400 with the worker performing the work and the type of work implement used for the work, but is not limited to this. The farm field data 310 may have any configuration as long as it is possible to identify the worker performing the next work and the next work implement 40 used by the worker. For example, the farm field data 310 may store information associating the work type, the worker, and the type of work implement used, regardless of the farm field 400. In this case, in step S160 shown in FIG. 7, the next work output unit 180 searches for the worker corresponding to the next work type determined from the farm field data 310 and the type of work implement used. The next work output unit 180 outputs the next work information to the terminal 200 of one of the workers found.

[0067] The above-described embodiment and modified examples are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily changed and / or arbitrarily combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, some or all of the processing of the work management apparatus 100 may be executed by the terminal 200. Also, some or all of the processing of the terminal 200 may be executed by the work management apparatus 100. The work management program 320 may include a notification program 330. Also, the work management system 1000 may not include the terminal 200 and may output the next work information to an external terminal not included in the work management system 1000. In this case, the external terminal notifies the user of the next work information.

[0068] 7 may be changed without impairing the functions. For example, the work management apparatus 100 may execute the process of step S130 after the process of step S150. When information representing the field 400 where the work is to be performed is registered in advance in the work management apparatus 100, the process of step S110 may be omitted.

[0069] In step S160 shown in FIG. 7, an example has been shown in which the next work output unit 180 outputs information identifying the field, the name of the next work type, and the type of work implement 30 to be used in the next work as next work information related to the next work, but only some of this information may be output. For example, the next work output unit 180 may output next work information indicating only the name of the next work type. A user, for example a worker, checks the type of work implement 30 to be used in the next work based on the name of the next work type. Furthermore, the next work output unit 180 may output next work information indicating only the type of work implement 30 to be used in the next work. In this case, a user, for example a worker, checks the work type of the next work based on the type of work implement 30. [Explanation of symbols]
