Description

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

In recent years, the use of information processing technology for cultivation management has been studied.

Patent Literature 1 discloses a system that manages the progress of work performed in a plurality of fields. The system prompts the worker for progress input as the work vehicle enters the field to perform the work. This system calculates the progress of work in all of a plurality of farm fields based on the input progress status and pre-registered information on the farm field where work is to be performed.

Japanese Patent No. 6069139

In the technique described in Patent Literature 1, it is necessary for the worker to input the progress of work in each field and to register in advance information about the field where the work is to be performed. Therefore, when the number of farm fields increases, the registration work becomes complicated. In addition, depending on the field conditions, such as the shape, size, and slope, there are cases where work is performed without using a work vehicle. Therefore, the system may not be able to calculate an accurate progress.

In view of the above situation, one of the objects of the present disclosure is to support progress management by users. Other objects can be understood from the following description and the description of the embodiments.

Means for solving the problems will be described below using the numbers and symbols used in the mode for carrying out the invention. These numbers and symbols are added in parentheses for reference in order to show an example of correspondence between the description of the claims and the mode for carrying out the invention. Therefore, the claims should not be construed as limiting by the parenthesized description.

A work management method according to one embodiment for achieving the above object includes determining a first target area where target work is scheduled to be performed using one or more work devices (30) in a plurality of fields based on work history data (310) representing work performed in a plurality of fields. Further, the work management method includes determining a progress amount of the target work in the first target area based on the first completion area in which the target work is completed by one or more work devices (30) and the first target area.

A work management system (1000) according to one embodiment for achieving the above object comprises a target area determination unit (160) and a progress amount determination unit (180). A target area determination unit (160) determines a first target area in which target work is scheduled to be performed using one or more work devices (30) in a plurality of fields based on work history data (310) representing work performed in a plurality of fields. A progress amount determination unit (180) determines the progress amount of the target work in the first target area based on the first target area and the first completion area in which the target work has been completed by one or more work devices (30).

A work management program (320) according to one embodiment for achieving the above object causes a computing device (120, 220) to determine a first target area where target work is to be performed using one or more work devices (30) in a plurality of fields based on work history data (310) representing work performed in a plurality of fields. Further, the work management program (320) causes the arithmetic device (120, 220) to determine the progress amount of the target work in the first target area based on the first completion area in which the target work is completed by one or more work devices (30) and the first target area.

According to the above aspect, the user can easily check the progress of the work.

It is a flow chart showing processing by a work management system in one embodiment. In one embodiment, it is a figure showing the progress amount of the object work displayed by the terminal. In one embodiment, it is a figure showing the amount of work of each time displayed by a terminal.

(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, a work management system 1000 includes a work management device 100 and a terminal 200, as shown in FIG. The work management device 100 is communicably connected to a terminal 200 and one or more work devices 30 via a network 20 such as the Internet.

The work management apparatus 100 determines the amount of progress of the work performed by the work device 30, for example, the progress rate, based on the completion information representing the completed area where work has been completed by the work device 30 and the target information representing the target area where work is to be performed. The work management device 100 determines the completion area based on the position information of the work device 30 . The work device 30 includes, for example, a harvester that harvests crops, and moves in a field to perform work. The work device 30 may be a vehicle, such as a tractor, that tows a work machine that performs work. The working device 30 may be a vehicle for transplanting seedlings, such as a rice transplanter or a transplanter. The working device 30 may be a vehicle for spraying materials, such as a sprayer (pesticide sprayer) or a fertilizer applicator. For example, the work device 30 includes a positioning device such as a GNSS (Global Navigation Satellite System) receiver, and acquires position information representing the position at each time when the work device 30 moves. The acquired position information is output from the work device 30 to the work management device 100 .

The work management device 100 determines a target area to be worked on based on work history data 310 representing work performed in a plurality of fields in the past. For example, the work management apparatus 100 determines, as the target area, an area of a field in which work has been performed by the work device 30 in the past, among the plurality of fields. Further, when work is performed by the work device 30 on a field in which work has not been performed by the work device 30 in the past, the work management device 100 adds this field region to the target region.

The work management apparatus 100 determines the progress amount of the work in the target area based on the target area and the completion area. By limiting the target area to the area of the field where the work is performed by the work device 30, a more accurate amount of progress can be determined.

The one or more work devices 30 may also include work devices 30 without positioning devices. In this case, the work management device 100 determines the completion area according to the ratio of the work devices 30 that do not have the positioning device among the work devices 30 . Thereby, the work management system 1000 determines a more accurate amount of progress.

The determined amount of progress is displayed on the terminal 200 as shown in FIG. The terminal 200 displays the progress amount, the ratio of the target area to the area of all fields, and the ratio of the working devices 30 without positioning devices to the working devices 30 . A user, for example, a work manager, confirms the amount of progress and the amount of correction used to determine the amount of progress, such as the ratio of the area of the target region to the area of a plurality of fields. As a result, the user can grasp the more accurate amount of progress and the amount of correction thereof. Thus, the work management system 1000 supports progress management by the user.

(Configuration of work management system)
The configuration of the work management device 100 included in the work management system 1000 shown in FIG. 1 will be described. The work management device 100 includes an input/output device 110 , an arithmetic device 120 , a communication device 130 and a storage device 140 . Work management device 100 is, for example, a computer. Input/output device 110 receives input of information for arithmetic device 120 to execute processing. The input/output device 110 also outputs the result of the processing executed by the arithmetic device 120 . The input/output device 110 includes various input devices and output devices, such as keyboards, mice, microphones, displays, speakers, and touch panels. 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 work device 30 to the arithmetic device 120 . Also, the signal generated by the arithmetic device 120 is transferred to the terminal 200 . The communication device 130 includes various interfaces such as NIC (Network Interface Card) and USB (Universal Serial Bus).

The storage device 140 stores various data for determining the progress of work by the work device 30 , such as field data 300 , work history 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 the computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

The farm field data 300 stores information about a plurality of farm fields. For example, the field data 300 stores field names, regions, and areas, as shown in FIG. The area represents an area included in the field, and represents, for example, the positions of a plurality of vertices representing the outline of the field. The area represents the area of the field. The field name, area, and area are registered in advance by the user.

In addition, the farm field data 300 stores information about the target work for determining the amount of progress. For example, the field data 300 represents, for each field, the scheduled work time, the target field indicating whether or not the target work is required, the device work field indicating whether or not work is performed by the work device 30, and the work status. The scheduled work time represents the time when the target work is scheduled to be performed in the field, and is registered in advance by the user. For example, the user may select each field and register the scheduled work time, or may select an area including multiple fields, field attribute information, such as owner, producer, planted variety, planting time (month, early-mid-late, week), etc., and register them collectively for multiple fields. The scheduled work time may represent one day when the work is scheduled to be performed, or may be represented by a period including a plurality of days.

The target field indicates whether or not the target work is performed in the field. When the field corresponds to the target field, it means that the target work is performed in the field. For example, when the target work is harvesting, an uncultivated field does not correspond to the target field because the target work is not performed. In the example shown in FIG. 3, "field A", "field B", "field C", and "field E" correspond to target fields in which the target work is performed, and "field D" corresponds to the non-target field in which the target work is not performed. The target agricultural field is determined by the computing device 120, for example.

The device work field indicates whether or not work was performed by the work device 30 in each field in the past. For example, in a field, when the target work for which the amount of progress is to be determined has been performed by the work device 30 in the past, the field corresponds to the device work field. The example shown in FIG. 3 indicates that “field A”, “field B”, and “field D” correspond to device working fields in which the target work was performed by the working device 30 in the past, and that “field C” and “field E” are not subject work by the working device 30 and do not correspond to device working fields. The device working field is determined by the computing device 120, for example.

The work status indicates whether or not the target work for determining the progress amount has been performed in the target field. The example shown in FIG. 3 indicates that the target work is currently being performed in "field B" and "field C" and the target work is not being performed in "field A" and "field E". The working state is determined by the computing device 120, for example.

The work history data 310 shown in FIG. 1 represents work performed in the past in a plurality of fields. For example, work performed in the past in a plurality of fields may be represented by operation information acquired from the work device 30 . The operation information represents the state of the working device 30 at each time, such as the speed of the working device 30, the steering angle, the engine speed, the ON/OFF status of various clutches, and the like. Further, when the work device 30 is a vehicle that tows the work machine, the operation information may include information such as the number of PTO (power take-off) revolutions when power is transmitted to the work machine, and the hitch height and lift arm angle that indicate the posture of the work machine. The operating information may include the amount of work performed by the work device 30 . For example, when the working device 30 is a vehicle for transplanting or spreading materials, the operation information may include information such as the amount of planting and the amount of spreading (nozzle opening and shutter opening). Further, the work history data 310 may represent work types determined based on the operation information, such as planting, fertilizer application, pesticide application, and harvesting.

The work history data 310 may also include images obtained by capturing fields from above, such as aerial photographs, satellite images, normalized difference vegetation index (NDVI), and the like. The work history data 310 may represent the type of work determined based on changes in features represented in the imaged area. For example, the work history data 310 may indicate that “planting” was performed in an area where soil was represented in the image at the first time point and crops were represented in the image at the second time point.

The computing device 120 shown in FIG. 1 is used for various data processing for executing the work management program 320 and determining the amount of progress of work by the work device 30 . For example, the arithmetic unit 120 includes a central processing unit (CPU) and the like.

By reading and executing the work management program 320, the arithmetic unit 120 implements a data storage unit 150, a target area determining unit 160, a completed area determining unit 170, and a progress amount determining unit 180, as shown in FIG. The data storage unit 150 stores field data 300 and work history data 310 . The target area determination unit 160 determines a target area on which work is to be performed by the work device 30 . The completed area determining unit 170 determines a completed area where work has been completed by the work device 30 . The progress amount determination unit 180 determines the progress amount of the work by the work device 30 based on the completion area and the target area.

The target area determination unit 160 includes a non-target field determination unit 161 and a device work field determination unit 162 . The non-target field determination unit 161 determines a field on which target work is to be performed, among a plurality of fields. The device work field determination unit 162 determines a field on which work is performed by the work device 30 among the plurality of fields.

Next, the configuration of terminal 200 will be described. The terminal 200 includes an input/output device 210, an arithmetic device 220, a communication device 230, and a storage device 240, as shown in FIG. Terminals 200 include, for example, computers, tablets, mobile phones, and the like. Input/output device 210 receives information for arithmetic device 220 to execute processing. Also, the input/output device 210 outputs the result of the processing executed by the arithmetic device 220 . The input/output device 210 includes various input devices and output devices, such as keyboards, mice, microphones, displays, speakers, and touch panels.

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 signal generated by the computing device 220 is transferred to the work management device 100 . The communication device 230 includes, for example, various interfaces such as a transmitter/receiver used for wireless communication such as a wireless LAN (Local Area Network) and a cellular network, a NIC (Network Interface Card), and a USB (Universal Serial Bus).

The storage device 240 stores various data for displaying the progress of work by the work device 30, such as a display program 330. FIG. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 330 . The display program 330 may be provided as a computer program product recorded on the computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The display program 330 may be recorded in the storage medium 1 and provided.

By reading and executing the display program 330, the arithmetic device 220 cooperates with the input/output device 210 to implement the display unit 250 as shown in FIG. The display unit 250 acquires from the work management apparatus 100 progress information indicating the amount of progress of the work performed by the work device 30, and displays the acquired progress information.

(Operation of work management device)
Arithmetic device 120 of work management device 100 , upon receiving the position information from work device 30 , reads and executes work management program 320 . By executing the work management program 320, the computing device 120 executes the processing shown in FIG. 5, which is the work management method.

In step S110, the non-target field determination unit 161 realized by the arithmetic device 120 determines non-target fields, for example, non-cultivated fields, on which the target work for determining the progress amount is not performed, based on the work history data 310 representing the work performed in the past. For example, the non-target field determination unit 161 determines non-target fields based on the image of the field captured from above included in the work history data 310 . For example, the non-target field determination unit 161 determines a field included in an area in which crops are not captured as a non-target field. The non-target field determination unit 161 registers in the field data 300 that the target work for determining the progress amount is not performed in the non-target field among the plurality of fields included in the field data 300 shown in FIG. For example, in the example shown in FIG. 3, "field D" is determined as a non-target field, and "field A", "field B", "field C", and "field E" are target fields where the target work for determining the progress amount is scheduled to be performed.

In step S120, the device work field determination unit 162 determines the device work field for performing the target work whose progress amount is to be determined by the work device 30, based on the work history data 310 representing the work performed in the past. For example, the device work field determination unit 162 acquires from the work history data 310 the position information of the work devices 30 that have previously performed the target work for determining the progress amount. The device working field determination unit 162 extracts a field including the position represented by the acquired position information from among the plurality of fields included in the farm field data 300, and registers the extracted farm field in the farm field data 300 as a device working field. For example, when the target work for determining the amount of progress is harvesting, the device work field determination unit 162 registers, from the work history data 310, the field that the work device 30 entered in the past for harvesting as the device work field in the field data 300. For example, in the example shown in FIG. 3 , “field A”, “field B”, and “field D” correspond to device work fields where target work was performed by the work device 30 in the past. “Field C” and “field E” have not been subjected to the target work by the work device 30 in the past, and do not correspond to the device work fields.

In step S130, the completed area determination unit 170 determines the completed area where the target work for determining the progress amount was performed by the task device 30 based on the position information acquired from the task device 30 that performs the target work for determining the progress amount. For example, the completion area determination unit 170 determines a convex hull including the positioning position represented in the position information of the work device 30 as the completion area. The convex hull represents the smallest area containing all positioning positions. Also, the completed area may represent an area obtained by expanding the contour of the convex hull outward by the working width of the working device 30 . 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 from the position of the positioning device provided in the working device 30 to the edge of the area in which the working device 30 works in the width direction of the working device 30 . The working width represents the distance from the position of the positioning device provided in the working device 30 to the end of the area in which the agricultural machine works in the width direction of the working device 30 when the tractor pulls the agricultural machine.

Further, the completion area determination unit 170 may determine the completion area based on the movement trajectory along which the work device 30 has moved. For example, the completed region determination unit 170 determines a movement trajectory in which the measured positions represented by the position information are connected by lines, for example, straight line segments in the order of the times when the positions were measured. The completion area determination unit 170 determines an area whose distance from the movement trajectory is within the working width of the work device 30 as a completion area.

Further, the completion area determination unit 170 may determine the area of the farm field including the positioning position represented by the position information of the work device 30 as the completion area. When the area of the farm field included in the completed area is larger than the area of a predetermined ratio of the farm field, the completed area determining unit 170 considers that the target work in the farm is completed and registers "completed" in the work status of the farm field data 300 shown in FIG. For example, in the example shown in FIG. 3 , the work device 30 has completed the target work for determining the amount of progress in the “farm field B”.

In step S140 shown in FIG. 5, the target area determining unit 160 determines a target area where the target work for determining the progress amount is performed by the working device 30 based on the farm field data 300 and the completed area. For example, the target area determination unit 160 extracts a field including a completed area from among the plurality of fields registered in the field data 300 shown in FIG. 3, and registers the extracted field in the field data 300 as a device work field. As a result, in the work history data 310, the field in which the target work is not performed by the work device 30 and the target work is currently performed by the work device 30 is registered in the farm field data 300 as the device work field. Based on the updated field data 300, the target area determination unit 160 determines, as the target area, a field area corresponding to the target field and the device operation field. For example, in the example shown in FIG. 3, the area of "field A" and the area of "field B" corresponding to the target field and the device operation field are determined as target areas. In addition, the target area determining unit 160 registers, in the field data 300, the field including the completed area as the device work field.

In addition, the target area determining unit 160 adds, to the target area, the target area in which the target work for determining the progress amount is performed and the scheduled work time has not yet passed. For example, the target area determination unit 160 extracts, from among the plurality of fields registered in the field data 300, fields that correspond to target fields and that do not correspond to device operation fields. The target area determination unit 160 adds, among the extracted fields, areas of the farm fields for which the scheduled work time has not yet passed to the target areas. For example, in the example shown in FIG. 3, when the current time is October 20, the area of "field E" which corresponds to the target field, does not correspond to the device operation field, and has not passed the scheduled work time is added to the target area.

Here, the target area determination unit 160 does not add to the target area the area of the farm field that has passed the scheduled work time among the target fields for which the target work for determining the amount of progress is to be performed and that do not correspond to the device work fields. In this case, the target area determining unit 160 determines that the target work will be performed without using the work device 30 in the field whose work state is to be registered. In the example shown in FIG. 3 , the target area determining unit 160 excludes the area of “field C” that corresponds to the target field, does not correspond to the device operation field, and has passed the scheduled work time from the target area. After that, when the target work is performed by the work device 30 in the "field C", the "field C" includes the completion area. Therefore, "field C" corresponds to the target field and the device operation field, and is included in the target area.

In step S150 shown in FIG. 5, the progress amount determination unit 180 determines the progress amount of the target work by the work device 30 based on the target area and the completion area. For example, based on the field data 300 shown in FIG. 3, the progress amount determination unit 180 calculates the area of the target region by summing the area of the farm field included in the target region, which in the example shown in FIG.

In addition, the progress amount determination unit 180 calculates the area of the completed area where the target work for which the progress amount is to be determined has been performed by the working device 30 . The work devices 30 that work in a plurality of fields may include an output work device that outputs positioning information to the work management device 100 and a non-output work device that does not output the positioning information to the work management device 100 . In this case, the device ratio of the quantity of the output working devices to the quantity of all the working devices 30 is registered in advance in the progress amount determination unit 180 . The progress amount determining unit 180 corrects the area of the completed area determined by the completed area determining unit 170 based on the device ratio. For example, the progress amount determining unit 180 multiplies the area of the completed area by the reciprocal of the device ratio to determine the area of the completed area in which the target work for which the progress amount is to be determined has been performed by all the work devices 30 . When the working devices 30 that work in a plurality of fields do not include non-output working devices that do not output positioning information, the area of the completed region determined by the completed region determining unit 170 may be calculated, and the area of the completed region where the countermeasure work has been performed by all the working devices 30 may be determined.

The progress amount determination unit 180 calculates the area of the completed area with respect to the calculated area of the target area as the amount of progress. The progress amount determination unit 180 outputs progress information representing the calculated progress amount to the terminal 200 . The progress information may include correction information representing the correction amount used to calculate the progress amount. The correction amount represents, for example, the ratio of the area of the target area to the total area of the plurality of fields registered in the field data 300, the ratio of the number of non-output working devices to the number of all working devices 30, and the like.

In step S<b>160 shown in FIG. 5 , the display unit 250 of the terminal 200 displays a progress display image representing the progress information acquired from the work management device 100 on the input/output device 210 . The display unit 250 displays a progress image 500 as shown in FIG. 2, for example. The progress image 500 includes, for example, a progress graph 510 representing the amount of progress. The progress graph 510 is, for example, a pie chart representing the area of the completed area where work has been performed by the work device 30 and the area of the target area where the target work has not been performed.

Further, the display unit 250 may display the correction amount in the correction amount display area 520 together with the progress graph 510 . The correction amount may include, for example, the total area of a plurality of farm fields registered in the farm field data 300 . For example, as shown in FIG. 2, the total area of a plurality of farm fields registered in the farm field data 300 may be displayed as "registered area." Further, the correction amount may include the total area of the target area, and the total area of the target area may be displayed as the "scheduled area" where the target work is scheduled to be performed. Further, the correction amount may include the area of the completed area where the work has been performed by all the work devices 30, and the area of the completed area may be displayed as the "actual area".

The display unit 250 may display the ratio of the area of the target region to the total area of the plurality of fields registered in the field data 300 included in the correction amount as the “cultivation ratio”. In the example shown in FIG. 3, the "cultivation ratio" represents a value obtained by dividing the total area of fields corresponding to the "target fields", such as "field A", "field B", "field C", and "field E", by the total area of a plurality of fields registered in the field data 300. In addition, the display unit 250 may display the ratio of the area of the field corresponding to the device operation field to the area of the target region included in the correction amount as the “machine harvest ratio”. In the example shown in FIG. 3, the "machine harvest ratio" represents a value obtained by dividing the total area of fields corresponding to the "target field" and "apparatus operation field", such as "field A" and "field B", by the total area of fields corresponding to the "target fields", such as "field A", "field B", "field C", and "field E". Further, the display unit 250 may display the ratio of the number of non-output work devices to the number of all work devices 30 included in the correction amount as the “data acquisition ratio”.

The display unit 250 may display the total area of the target area as the "scheduled area" and the total area where the target work is scheduled to be performed by the work device 30 as the "scheduled machine work area".

The display unit 250 may display a graph 550 representing progress rates that change over time, as shown in FIG. The graph 550 may represent the time, for example, the date, when the target work is completed in all target areas based on the progress rate at each time.

Further, as shown in FIG. 7, the display unit 250 may display a graph 600 representing the work amount of the target work performed at each time, for example, each day, such as the work area and harvest amount. The workload of the target work performed at each time is determined, for example, based on the operation information output from the work device 30 , and represents the workload of the target work performed by all the work devices 30 .

In this way, the work management system 1000 notifies the user of the amount of progress and the amount of correction. This allows the user to grasp the progress of the target work. The work management apparatus 100 determines the target area where the target work is performed by the work device 30 based on the scheduled work time and the past work history, and determines the amount of progress. Therefore, the user can confirm the amount of progress of the target work by the working device 30 without distinguishing between a field using the working device 30 and a field not using the working device 30, for example, a field where work is performed manually. Further, the work management apparatus 100 corrects the completion area where the target work is completed based on the ratio of non-output work devices that do not output the position information included in the work device 30 . Therefore, even if the user includes a non-output work device that does not output position information, the user can grasp the progress of the target work.

The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not hinder the functions. For example, in step S110 shown in FIG. 5, the non-target field determining unit 161 may exclude from the non-target fields an area in which one or more working devices 30 have performed work during a predetermined period, for example, the cultivation period of the crops to which the target work should be performed. For example, a field including the position represented by the position information of the working device 30 during the cultivation period is excluded from the non-target fields.

Further, the non-target field determination unit 161 may determine non-target fields based on the scheduled work time of the field data 300 shown in FIG. For example, the non-target field determination unit 161 may determine a field whose scheduled work time is not registered as a non-target field.

In addition, the non-target field determination unit 161 may determine the timing of the first work performed in a plurality of fields based on the work history data 310, for example, the planting work, and may determine the non-target fields based on the determined timing of the first work. For example, when planting operations occur at different times, operations performed in fields, such as harvesting operations, differ from each other. Therefore, the timing of the target work with respect to the timing of the first work is registered in advance in the non-target field determination unit 161 . The non-target field determination unit 161 determines whether or not the target work will be performed in the field based on the time of the first work performed in the field, the current time, and the time of the target work relative to the time of the first work. When determining that the target work is not performed in the corresponding field, the non-target field determination unit 161 determines the corresponding field as a non-target field.

In step S120 shown in FIG. 5, the device work field determination unit 162 may register, in the field data 300, a field in which the most recently performed target work among the target work performed in the past is being performed by the work device 30 in each field as the device target field. For example, from the work history data 310, the device work field determination unit 162 extracts information about the most recent target work among the target works that were performed in the past in each field. When the extracted information includes the position information of the working device 30, the device working field determining unit 162 registers in the field data 300 that the working device 30 has performed work in the corresponding field.

In addition, the device work field determining unit 162 may register in the field data 300, among the target work performed in the past, a field in which the target work was performed by the work device 30 for a predetermined period, for example, from one year ago to the present, as the device target field. The predetermined period may represent the previous cultivation period, for example, the period during which the target work was performed in the last season in each field.

Further, when the extracted information includes an image taken from above, the device work field determination unit 162 determines whether the field region represented by the image shows a trace of the movement of the work device 30, for example, a track of a crawler or a wheel. When the trajectory of the work device 30 is represented in the area of the field, the device work field determination unit 162 registers in the field data 300 that the work by the work device 30 was performed in that field.

In step S150 shown in FIG. 5, the progress amount determining unit 180 corrects the area of the completed area when the non-output working device that does not output the positioning information to the working device 30 is included, but the area of the target region may be corrected. For example, the progress amount determination unit 180 corrects the target area determined by the target area determination unit 160 by accumulating the ratio of the number of non-output work devices to the number of all work devices 30 . The progress amount determination unit 180 determines the progress amount by dividing the area of the completed area by the corrected target area.

In step S160 shown in FIG. 5, the display unit 250 of the terminal 200 may display progress information for each field group including one or more fields. In this case, the field data 300 shown in FIG. 3 stores information representing the field group to which each field belongs. The progress amount determination unit 180 of the work management apparatus 100 determines the progress amount of each farm field group, and outputs progress information indicating the determined progress amount of each farm field group to the terminal 200 .

Further, in step S140, the target area determination unit 160 may add, to the target area, an area of a field that has passed the scheduled work time among the target fields that are not device operation fields. In this case, the completion area determination unit 170 similarly adds an area of a field whose work schedule time has passed among the target fields and not the device operation fields to the completion area.

The embodiments and modifications described above are examples, and the configurations described in each embodiment and modifications may be arbitrarily changed and/or combined as long as the functions are not hindered. Furthermore, some of the functions described in the embodiment and modifications may be omitted as long as the required functions can be realized. For example, the terminal 200 may perform part or all of the processing of the work management device 100 . Moreover, the work management apparatus 100 may perform a part or all of the processing of the terminal 200 . Work management program 320 may include display program 330 . Moreover, the work management system 1000 may display the progress information on an external terminal that does not include the terminal 200 and is not included in the work management system 1000 .

Also, the order of the flowchart shown in FIG. 5 may be changed as long as the functions are not hindered. For example, the work management apparatus 100 may execute the process of step S110 after the process of step S130, or may execute the process of step S120 after the process of step S130. Further, the processing of step S110 and the processing of step S120 may be performed only once before the target work is started. In this case, when the work management device 100 acquires the position information from the work device 30, the processing from step S130 to step S160 is executed.

Further, the information representing the target farm field on which the target work is to be performed may be input to the input/output device 210 of the terminal 200 by the user. In step S110 shown in FIG. 5, the non-target field determination unit 161 of the work management device 100 acquires the input information from the terminal 200, and determines the target field based on the acquired information.

Also, the target work may be performed in all of the plurality of fields registered in the field data 300 . In this case, the non-target agricultural field determination unit 161 of the work management device 100 may be omitted. Also, the process of step S110 shown in FIG. 5 may be omitted.
