Description

The present invention relates to a work management method, a work management system, and a work management program.

Even if the same work is being done in the field, such as harvesting, the next work to be done may differ depending on the work that was done in the field.

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 husks have been separated, on the farm for a short period of time to absorb moisture and then subjecting it to anaerobic fermentation.

Patent Document 2 also describes how, after harvesting grains, straw is tilled into the field to supplement the nitrogen source present in the field. In this case, as described in Patent Document 2, the straw is chopped by a combine harvester and discharged into the field.

In this way, even after the same grains have been harvested, the next work to be done may be different. In particular, when there are multiple 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 preparations for the next work are made in a location away from the field, preparations for a different work than was planned may be made.

In view of the above situation, one of the objectives of the present disclosure is to support the user by notifying the user of information regarding the next task based on the operation information of the work device performing work in the field. Other objectives can be understood from the following description and explanation of the embodiment.

(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.

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, such as a tractor. The working device 30 may be a vehicle that performs seedling transplant work, such as a rice transplanter or transplanter. The working device 30 may be a vehicle that sprays materials, such as a sprayer (pesticide sprayer) or a fertilizer applicator.

When the working device 30 moves and works within the field 400, it acquires operation information that indicates the state of the working device 30. 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 working machine, the operation information may include information such as the PTO (power take-off) speed when transmitting power to the working machine, and the hitch height and lift arm angle that indicate the attitude of the working machine. Furthermore, when the working device 30 is a harvester that harvests grains, the operation information may include information indicating whether or not the stalks (straw) after the rice grains are separated are cut, depending on the ON/OFF status of various clutches.

The work device 30 also includes a positioning device, such as a GNSS (Global Navigation Satellite System) receiver, and acquires location information indicating the location of the work device 30 at each time it moves. The acquired location information is included in the operation information.

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

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 understand 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, depending on 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. Also, when the next work is "plowing", the worker connects a "rotary tiller" to the tractor of the next work device 40.

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. The user, for example, a worker, can reduce work errors in the field 400 by checking the next work information related to the next work. In addition, the user, for example, a manager, can understand the work status without waiting for a report from the worker, 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 operation information may further include the amount of work performed by the work device 30. For example, when the work device 30 is a vehicle that harvests, the operation information may include information that indicates the harvest amount. Furthermore, when the work 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 and shutter opening).

(Configuration of Work Management System)
The configuration of a work management device 100 included in the work management system 1000 shown in Fig. 1 will be described. As shown in Fig. 2, the work management device 100 includes an input/output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input/output device 110. The input/output device 110 outputs the results of the processing executed by the calculation device 120. 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.

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

The storage device 140 stores various data for determining the type of work to be performed next in the field 400, such as work data 300, field data 310, and 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.

The work data 300 represents conditions for determining the work type of the next work depending on the work type of the work being performed in the field 400 and the type of work equipment 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 equipment 30, conditions, and the next work type. The work type represents the type of work being performed in the field 400, such as harvesting, turning over straw, plowing, straw compression and packaging, etc. The type of work equipment 30 represents the type of work equipment 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 represents the type of work to be performed next. When the conditions represented in the work data 300 are met, the work of the next work type corresponding to the conditions will be performed next.

For example, when "harvesting" is being performed by a "combine" in the field 400, if the condition that the proportion of work in which the combine cuts the 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 proportion of work in which the combine cuts the straw is less than a threshold is satisfied, the work management device 100 determines that "straw turning" will be performed next. Also, the work type of the next work may be 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/packaging" will be performed next.

The field data 310 shown in FIG. 4 stores information associating the type of work performed in each field 400, the worker performing the work, and the type of work equipment 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 equipment used. The field name represents the field 400 where 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 equipment used represents the type of work equipment 30 used when the corresponding worker performs the corresponding work.

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

The arithmetic device 120 shown in FIG. 2 executes the work management program 320 and is used for various data processing to determine the work type of the next work to be performed in the field 400. For example, the arithmetic device 120 includes a central processing unit (CPU) and the like.

The computing device 120 reads and executes the work management program 320 to realize 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 field data 310. The work status determination unit 160 determines the work status being performed in the field 400 based on the operation information acquired from the work device 30. For example, the work status determination unit 160 identifies the field 400 where the 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 field 400 based on the operation information acquired from the work device 30. The next work output unit 180 outputs the next work information related to the next work to the terminal 200.

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 computing device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the computing device 220 to execute processing is input to the input/output device 210. The input/output device 210 also outputs the results of the processing executed by the computing device 220. The input/output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 230 transfers information acquired from the work management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces such as a transceiver used for wireless communication such as a wireless LAN (Local Area Network) or a cellular network, a NIC (Network Interface Card), and a USB (Universal Serial Bus).

The storage device 240 stores various data for notifying the user of the next task information, such as the 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 on a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server.

The computing device 220 reads and executes the notification program 330, and cooperates 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.

(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.

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 that includes the position represented 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.

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 work device 30. For example, the work status determination unit 160 determines the ratio of the area where the work device 30 has performed work to the area of the field 400 as the progress amount. For example, the work status determination unit 160 determines the convex hull including the positioning positions indicated in the position information of the work device 30 as the completed area where the work device 30 has performed work. The convex hull represents the smallest area including all the positioning positions. The completed area may also represent the area obtained by expanding the outline of the convex hull outward by the work width of the work device 30. The work status determination unit 160 determines the area of the completed area as the area where the work device 30 has performed work. The work status determination unit 160 determines the progress amount by dividing the area of the field 400 where work is being performed by the area of the completed area.

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

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, where 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 device 30 in the field 400 is about to be completed. For example, the threshold value may be set to 80% or more, 90% or more, or 100%.

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, the next work determination unit 170 first 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 device 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 the corresponding conditions that "the proportion of work in which straw is cut is equal to or greater than a threshold value" and "the proportion of work in which straw is cut is less than a threshold value."

Next, the next work determination unit 170 determines which of the acquired conditions are 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.

The cutting work area may be determined, for example, based on the position where the work device 30 was cutting and discharging 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.

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

The next operation determination unit 170 determines the area of the 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 also represent the area of the region obtained by expanding the outline of the convex hull outward by the operation width of the operation device 30.

The next task determination unit 170 determines the task proportion of straw cutting among the tasks in the field 400 by dividing the cutting task area by the area of the field 400 where the task is being performed by the task device 30. 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 that are satisfied by the operation information.

In step S150 shown in FIG. 7, the next work determination unit 170 determines the next work type in the work data 300 that corresponds to the conditions satisfied by the operation information 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 next work to be performed is "plowing in." Also, when the work ratio of the work of cutting straw is less than the threshold value, it determines that the next work to be performed is "straw turning."

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 other users, such as the work manager or the owner of the field 400.

For example, based on the field data 310 shown in FIG. 4, when the field 400 where work is being performed is "Field A" and the next work type indicates "straw inversion", 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 to the terminal 200 of "Worker B", for example, information indicating that "straw inversion" will be performed using a "tedder rake" in "Field A".

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 unit 180 determines that the worker performing the next work is "Worker D" and that the type of next work device 40 to be used for the next work is a "rotary tiller". The next work output unit 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".

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.

The notification unit 250 may also notify a user, such as a work manager or the owner of the field 400, of the progress of the work being performed in the field 400 as the work status, in addition to the next work information. The user can grasp the work status in the field 400 by checking the progress of the work. In this case, the next work output unit 180 of the work management device 100 may output information indicating the progress of the work to the terminal 200, in addition to the next work information.

When a user who has been notified of the next task information, for example a worker performing the next task, performs the task using the next task device 40, the next task device 40 acquires operation information indicating the state of the next task device 40 and outputs the acquired operation information to the task management device 100. When the calculation device 120 of the task management device 100 receives the operation information from the next task device 40, it executes the process shown in FIG. 7. In step S110, the task status determination unit 160 of the task management device 100 identifies the field 400 in which the next task device 40 is performing the task based on the operation information of the next task device 40. Here, the next task device 40 may identify the field 400 in which the previous task was performed as the field 400 in which the task is being performed. Next, in step S120, the task status determination unit 160 determines the progress of the task.

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

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, based on the work data 300 shown in FIG. 3, the next work determination unit 170 determines that there is no condition and that "straw compression/packaging" will be performed next because "straw inversion" is being performed by a "tedder/rake".

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

In this way, the work management system 1000 can repeatedly execute the process shown in FIG. 7 until there is no more work to be done.

(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 task type used in the processing of step S140 shown in Fig. 7, specifically, the task type of the task being performed in the field 400, is registered in advance in the task management apparatus 100, but this is not limiting, and the task type may be determined by any method. The task type may be estimated by the task status determination unit 160 based on the operation information of the task device 30.

In addition, 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 device 100, but this is not limited thereto, 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 information on the sender included in the operation information acquired from the work device 30.

In step S120, the work status determination unit 160 has determined a convex hull including the positioning position indicated 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 this is not limited to the above, 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 that connects the positioning positions indicated in the position information in the order of the time of positioning with a line, for example a straight line segment. 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.

In addition, in step S120, the work status determination unit 160 may determine the amount of progress using any method. For example, the work status determination unit 160 may determine the amount of progress as 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 the amount of progress as the ratio of the amount of pesticide sprayed by the work device 30 to the amount of pesticide sprayed in the field 400.

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 in the order of the measured time of the positioning positions 500 with a line, for example, a straight line segment.

For example, the first positioning position 500-1 and the second positioning position 500-2 are adjacent to each other in the order of time when the positioning positions 500 were measured, so the next work determination unit 170 determines the line segment connecting the first positioning position 500-1 and the second positioning position 500-2 as part of the first cutting movement trajectory 560-1. Similarly, the next work determination unit 170 determines the line segment connecting the second positioning position 500-2 and the third positioning position 500-3 as part of the first cutting movement trajectory 560-1. Here, the third positioning position 500-3 and the seventh positioning position 500-7 are not adjacent to each other because they sandwich the fourth positioning position 500-4 to the sixth positioning position 500-6 in between in the order of time when the positioning positions 500 were measured. Because 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 way, the next task determination unit 170 determines the cutting movement trajectory 560.

The next work determination unit 170 determines the area of the region in which the distance of the determined cutting movement trajectory 560 is within the working width of the working device 30 as the cutting work area.

In addition, in step S140 shown in FIG. 7, the next work determination unit 170 may use any method to determine the work ratio that represents 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.

The work data 300 shown in FIG. 3 is an example in which conditions are stored corresponding to the work type and the work device 30 that performs the work, but is not limited to this. For example, the work data 300 may store conditions corresponding only to the work type. Furthermore, the work data 300 may store conditions corresponding to the work device 30.

The field data 310 shown in FIG. 4 stores information that associates the type of work performed in the field 400, the worker performing the work, and the type of work equipment used for the work, but is not limited to this. The field data 310 may have any configuration as long as it can identify the worker performing the next work and the next work equipment 40 used by the worker. For example, the field data 310 may store information that associates the work type, the worker, and the type of work equipment used, regardless of the 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 field data 310 and the type of work equipment used. The next work output unit 180 outputs the next work information to the terminal 200 of one of the searched workers.

The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be modified and/or combined as desired without impairing the functions. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the necessary functions can be realized. For example, some or all of the processing of the work management device 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 device 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.

The order of the flowchart shown in FIG. 7 may be changed as long as it does not impair functionality. For example, the work management device 100 may execute the process of step S130 after the process of step S150. When information representing the field 400 in which work is to be performed is registered in advance in the work management device 100, the process of step S110 may be omitted.

In step S160 shown in FIG. 7, the next work output unit 180 outputs information identifying the field, the name of the next work type, and the type of work equipment 30 to be used in the next work as next work information related to the next work. However, 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 equipment 30 to be used in the next work based on the name of the next work type. The next work output unit 180 may also output next work information indicating only the type of work equipment 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 equipment 30.
