Description

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

In recent years, research has been conducted into using information processing technology for cultivation management.

Patent Document 1 discloses a system for managing the progress of work carried out in multiple farm fields. When a work vehicle enters a farm field to carry out work, the system requests the worker to input the progress status. The system calculates the progress of work across the multiple farm fields based on the input progress status and pre-registered information about the farm field where the work is to be carried out.

Patent No. 6069139

The technology described in Patent Document 1 requires workers to input the progress of work in each field and to register information about the fields where work is planned to be carried out in advance. As a result, as the number of fields increases, the registration process becomes more cumbersome. Also, depending on the condition of the field, such as its shape, size, and slope, work may be carried out without using a work vehicle. As a result, the system may not be able to calculate an accurate progress status.

In view of the above circumstances, one of the objectives of this disclosure is to assist users in managing their progress. Other objectives can be understood from the following description and explanation of the embodiments.

The means for solving the problems will be explained 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.

To achieve the above object, a work management method according to one embodiment includes determining a first target area in a plurality of fields where the target work is to be performed using one or more work devices (30) based on work history data (310) representing work performed in the plurality of fields. The work management method also includes determining the progress of the target work in the first target area based on a first completion area in which the target work has been completed by one or more work devices (30) and the first target area.

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

In one embodiment of the work management program (320) for achieving the above object, the work management program (320) causes the calculation device (120, 220) to determine a first target area in which the target work is to be performed using one or more work devices (30) in multiple fields, based on work history data (310) representing work performed in multiple fields. The work management program (320) also causes the calculation device (120, 220) to determine the progress of the target work in the first target area, based on a first completion area in which the target work has been completed by one or more work devices (30) and the first target area.

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

(Embodiment 1)
A work management system 1000 according to the present 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 a terminal 200. 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 work management device 100 determines the progress amount, for example, the progress rate, of the work performed by the work device 30 based on the completion information indicating the completion area where the work device 30 has completed the work and the target information indicating the target area where the work is planned 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 within a field to perform work. The work device 30 may be a vehicle that pulls the work machine that performs the work, for example, a tractor. The work device 30 may be a vehicle that performs seedling transplant work, for example, a rice transplanter or transplanter. The work device 30 may be a vehicle that sprays materials, for example, a sprayer (pesticide sprayer) or a fertilizer applicator. For example, the work device 30 is equipped with a positioning device, for example, a GNSS (Global Navigation Satellite System) receiver, and acquires position information indicating the position of the work device 30 at each time it moves. The acquired location information is output from the work device 30 to the work management device 100.

The work management device 100 determines the target area where work is planned to be performed based on work history data 310 that represents work that has been performed in multiple fields in the past. For example, the work management device 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 multiple fields. Furthermore, when work is performed by the work device 30 in a field in which work has not been performed by the work device 30 in the past, the work management device 100 adds the area of this field to the target area.

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

In addition, one or more of the work devices 30 may include a work device 30 that does not have a positioning device. In this case, the work management device 100 determines the completion area according to the proportion of the work devices 30 that do not have a positioning device. This allows the work management system 1000 to determine a more accurate amount of progress.

The determined progress amount is displayed on the terminal 200 as shown in FIG. 2. Along with the progress amount, the terminal 200 displays the ratio of the target area to the area of all fields, and the ratio of work devices 30 that do not have positioning devices to the work devices 30. Along with the progress amount, a user, for example a work manager, checks the correction amount used to determine the progress amount, for example the ratio of the area of the target area to the area of multiple fields. This allows the user to grasp a more accurate progress amount and the correction amount. In this way, the work management system 1000 supports the user in progress management.

(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. 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 also outputs the results of the processing executed by the calculation device 120. The input/output device 110 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. 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 progress of work by the work device 30, such as farm 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 a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

The field data 300 stores information about multiple fields. For example, as shown in FIG. 3, the field data 300 stores the name, region, and area of the field. The area represents the area included in the field, and for example represents the positions of multiple vertices that represent the outline of the field. The area represents the area of the field. The name, region, and area of the field are registered in advance by the user.

Furthermore, the field data 300 stores information on the target work for which the progress amount is determined. For example, the field data 300 indicates, for each field, the planned work time, the target field indicating whether the target work is necessary, the equipment work field indicating whether work is performed by the work equipment 30, and the work status. The planned work time indicates 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 planned work time, or may select an area including multiple fields, field attribute information such as the owner, producer, crop variety, planting time (month, early, middle, late, week), etc., and register the information for multiple fields at once. The planned work time may indicate one day when the work is scheduled to be performed, or may be expressed as a period including multiple days.

The target field indicates whether or not the target work is performed in that field. When a field is a target field, it indicates that the target work is performed in that field. For example, when the target work is harvesting, a field that is not cultivated does not qualify as a target field because the target work is not performed on that field. In the example shown in FIG. 3, "Field A", "Field B", "Field C", and "Field E" qualify as target fields where the target work is performed, and "Field D" is a non-target field where the target work is not performed. The target fields are determined, for example, by the computing device 120.

The equipment work field indicates whether or not work has been performed by the work device 30 in the past in each field. For example, when the target work for which the progress amount is to be determined has been performed by the work device 30 in the past in a field, the field corresponds to an equipment work field. The example shown in FIG. 3 indicates that "Field A", "Field B", and "Field D" correspond to equipment work fields where the target work has been performed by the work device 30 in the past, and "Field C" and "Field E" do not correspond to equipment work fields where the target work has not been performed by the work device 30. The equipment work field is determined, for example, by the calculation device 120.

The work status indicates whether or not the target work for which the progress amount is to be determined 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 work status is determined, for example, by the computing device 120.

The work history data 310 shown in FIG. 1 represents work performed in the past in multiple fields. For example, the work performed in the past in multiple fields may be represented by operation information acquired from the work device 30. The operation information represents the state of the work device 30 at each time, for example, the speed, steering angle, engine speed, and ON/OFF status of various clutches of the work device 30. In addition, when the work 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. The operation information may include the amount of work performed by the work device 30. For example, 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). In addition, the work history data 310 may represent the type of work determined based on the operation information, for example, planting, fertilizer spraying, pesticide spraying, harvesting, etc.

Furthermore, the work history data 310 may include images obtained by photographing the field from the sky, such as aerial photographs, satellite images, and normalized difference vegetation index (NDVI). The work history data 310 may represent a work type determined based on changes in features depicted in an area captured in an image. For example, when an image at a second time point shows a crop in an area where soil is depicted in an image at a first time point, the work history data 310 may represent that "planting" was performed in that area.

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

By reading and executing the work management program 320, the calculation device 120 realizes a data storage unit 150, a target area determination unit 160, a completed area determination unit 170, and a progress amount determination unit 180, as shown in FIG. 4. The data storage unit 150 stores farm field data 300 and work history data 310. The target area determination unit 160 determines a target area where work is planned to be performed by the work device 30. The completed area determination 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 work by the work device 30 based on the completed area and the target area.

The target area determination unit 160 includes a non-target field determination unit 161 and an equipment work field determination unit 162. The non-target field determination unit 161 determines, from among the multiple fields, a field in which the target work will be performed. The equipment work field determination unit 162 determines, from among the multiple fields, a field in which work will be performed by the work equipment 30.

Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, 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 displaying the progress of work performed by the work device 30, such as a display program 330. 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 a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The display program 330 may be provided by being recorded on a storage medium 1.

The computing device 220 reads and executes the display program 330, and cooperates with the input/output device 210 to realize the display unit 250 as shown in FIG. 4. The display unit 250 acquires progress information indicating the amount of progress of work by the work device 30 from the work management device 100, and displays the acquired progress information.

(Operation of the work management device)
When the arithmetic device 120 of the work management apparatus 100 receives the position 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. 5, which is a work management method.

In step S110, the non-target field determination unit 161 realized by the calculation device 120 determines a non-target field where the target work for determining the progress amount is not performed, for example, a field where no cultivation is being performed, based on the work history data 310 representing work performed in the past. For example, the non-target field determination unit 161 determines a non-target field based on an image of the field captured from the air and included in the work history data 310. For example, the non-target field determination unit 161 determines a field included in an area where no crops are 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 multiple fields included in the field data 300 shown in FIG. 3. For example, the example shown in FIG. 3 indicates that "Field D" is a determined non-target field, and "Field A," "Field B," "Field C," and "Field E" are target fields where the target work for which the progress amount is to be determined is scheduled to be performed.

In step S120, the device work field determination unit 162 determines the device work field where the target work for which the progress amount is to be determined is performed by the work device 30 based on the work history data 310 that indicates the work performed in the past. For example, the device work field determination unit 162 acquires the position information of the work device 30 that performed the target work for which the progress amount is to be determined in the past from the work history data 310. The device work field determination unit 162 extracts a field that includes the position represented in the acquired position information from the multiple fields included in the field data 300, and registers the extracted field as a device work field in the field data 300. For example, when the target work for which the progress amount is to be determined is harvesting, the device work field determination unit 162 registers a field that the work device 30 entered in the past to harvest from the work history data 310 as a device work field in the field data 300. For example, in the example shown in FIG. 3, "Field A," "Field B," and "Field D" are equipment-operated fields where target work has been performed by the work device 30 in the past. "Field C" and "Field E" are not equipment-operated fields where target work has not been performed by the work device 30 in the past.

In step S130, the completion area determination unit 170 determines the completion area in which the target work for which the progress amount is to be determined has been performed by the work device 30, based on the position information acquired from the work device 30 performing the target work for which the progress amount is to be determined. For example, the completion area determination unit 170 determines a convex hull including the positioning positions indicated in the position information of the work device 30 as the completion area. The convex hull represents the smallest area including all the positioning positions. The completion area may also represent an area obtained by expanding the outline of the convex hull outward by the working width of the work device 30. The working width of the work device 30 is registered in advance by the work device 30. For example, the working width represents the distance in the width direction of the work device 30 from the position of the positioning device provided on the work device 30 to the edge of the area in which the work device 30 performs work. The working width represents the distance in the width direction of the work device 30 from the position of the positioning device provided on the work device 30 to the edge of the area in which the work device performs work when the tractor tows the agricultural machine.

The completed area determination unit 170 may also determine the completed area based on the movement trajectory of the work device 30. For example, the completed area determination unit 170 determines a movement trajectory that connects the measured positions indicated in the position information in the order of the time of measurement with a line, for example, a straight line segment. The completed area determination unit 170 determines an area whose distance from the movement trajectory is within the working width of the work device 30 as the completed area.

The completed area determination unit 170 may also determine the area of the field that includes the positioning position indicated in the position information of the work device 30 as the completed area. When the area of the field area included in the completed area is greater than a predetermined percentage of the area of the field area, the completed area determination unit 170 determines that the target work in the field is completed, and registers "completed" as the work status in the field data 300 shown in FIG. 3. For example, in the example shown in FIG. 3, the target work in "field B" for which the progress amount is to be determined has been completed by the work device 30.

In step S140 shown in FIG. 5, the target area determination unit 160 determines the target area where the target work for which the progress amount is to be determined is performed by the work device 30 based on the 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 multiple fields registered in the field data 300 shown in FIG. 3, and registers the extracted field as an equipment work field in the field data 300. As a result, a field in which the target work is not performed by the work device 30 in the work history data 310 and in which the target work is currently performed by the work device 30 is registered in the field data 300 as an equipment work field. Based on the updated field data 300, the target area determination unit 160 determines the area of the field that corresponds to the target field and the equipment work field as the target area. For example, in the example shown in FIG. 3, the area of "field A" and the area of "field B" that correspond to the target field and the equipment work field are determined as the target fields. In addition, the target area determination unit 160 registers the field that includes the completed area as the equipment work field in the field data 300.

In addition, the target area determination unit 160 adds to the target area, among the target fields in which the target work for which the progress amount is to be determined is performed in the field data 300 shown in FIG. 3, the area of the field that has not yet passed the planned work period. For example, the target area determination unit 160 extracts, among the multiple fields registered in the field data 300, fields that are target fields and are not equipment work fields. The target area determination unit 160 adds to the target area, among the extracted fields, the area of the field that has not yet passed the planned work period. For example, in the example shown in FIG. 3, when the current time is October 20th, the area of "field E" that is a target field, is not an equipment work field, and has not yet passed the planned work period is added to the target area.

Here, the target area determination unit 160 does not add to the target area the area of a field that corresponds to the target field where the target work for which the progress amount is to be determined is performed and that does not correspond to an equipment work field, and where the planned work time has passed. In this case, the target area determination unit 160 determines that the target work will be performed without using the work device 30 in the field for which the work status is registered. In the example shown in FIG. 3, the target area determination unit 160 excludes from the target area the area of "field C" that corresponds to the target field, does not correspond to an equipment work field, and where the planned work time has passed. After this, when the target work is performed by the work device 30 in "field C", "field C" comes to include a completed area. Therefore, "field C" corresponds to both the target field and the equipment work 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 completed 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 area by adding up the areas of the fields included in the target area, in the example shown in FIG. 3, the areas of "Field A", "Field B", and "Field E".

The progress amount determination unit 180 also calculates the area of the completed area where the target work for which the progress amount is determined is performed by the work device 30. The work devices 30 performing work in multiple fields may include output work devices that output positioning information to the work management device 100 and non-output work devices that do not output positioning information to the work management device 100. In this case, the progress amount determination unit 180 pre-registers the device ratio of the number of output work devices to the number of all work devices 30. The progress amount determination unit 180 corrects the area of the completed area determined by the completed area determination unit 170 based on the device ratio. For example, the progress amount determination unit 180 multiplies the area of the completed area by the reciprocal of the device ratio to determine the area of the completed area where the target work for which the progress amount is determined is performed by all work devices 30. When the work devices 30 performing work in multiple fields do not include non-output work devices that do not output positioning information, the area of the completed area determined by the completed area determination unit 170 may be calculated, and the area of the completed area where the corresponding work is performed by all work devices 30 may be determined.

The progress amount determination unit 180 calculates the area of the completed area relative to the calculated area of the target area as the progress amount. The progress amount determination unit 180 outputs progress information indicating the calculated progress amount to the terminal 200. The progress information may include correction information indicating a correction amount used to calculate the progress amount. The correction amount indicates, for example, the ratio of the area of the target area to the total area of multiple fields registered in the field data 300, the device ratio of the number of non-output work devices to the number of all work devices 30, etc.

In step S160 shown in FIG. 5, the display unit 250 of the terminal 200 displays a progress display image showing 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, for example, as shown in FIG. 2. The progress image 500 includes, for example, a progress graph 510 showing the amount of progress. The progress graph 510 is, for example, a pie chart showing 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.

The display unit 250 may also 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 multiple fields registered in the field data 300. For example, as shown in FIG. 2, the total area of multiple fields registered in the field data 300 may be displayed as the "registered area." The correction amount may also include the total area of the target area, and the total area of the target area may be displayed as the "planned area" where the target work is planned to be performed. The correction amount may also include the area of the completed area where work has been performed by all 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 area to the total area of the multiple fields registered in the field data 300 included in the correction amount as the "cultivation ratio". In the example shown in Figure 3, the "cultivation ratio" represents the value obtained by dividing the total area of the fields corresponding to the "target fields", such as "Field A", "Field B", "Field C", and "Field E", by the total area of the multiple fields registered in the field data 300. The display unit 250 may also display the ratio of the area of the fields corresponding to the equipment work fields to the area of the target area included in the correction amount as the "mechanical harvest ratio". In the example shown in FIG. 3, the "mechanical harvest ratio" represents the value obtained by dividing the total area of the fields corresponding to the "target field" and the "equipment work field", such as "field A" and "field B", by the total area of the fields corresponding to the "target field", such as "field A", "field B", "field C", and "field E". In addition, the display unit 250 may display the equipment ratio of the number of non-output work equipment to the number of all work equipment 30 included in the correction amount as the "data acquisition ratio".

The display unit 250 may display the total area of the target region as the "planned area" and the total area on which the target work is planned to be performed by the work device 30 as the "planned machine work area."

The display unit 250 may display a graph 550 showing the progress rate changing over time, as shown in FIG. 6. The graph 550 may show the time, e.g., date, when the target work is completed in all target areas based on the progress rate at each time.

The display unit 250 may also display a graph 600 showing the amount of work, such as the work area or harvest volume, of the target work performed at each time, for example, on each day, as shown in FIG. 7. The amount of work 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 amount of work of the target work performed by all the work devices 30.

In this way, the work management system 1000 notifies the user of the progress amount and the correction amount. This allows the user to grasp the progress status of the target work. The work management device 100 determines the target area where the target work is performed by the work device 30 based on the scheduled work time and past work history, and determines the progress amount. Therefore, the user can check the progress amount of the target work by the work device 30 without having to distinguish and register fields where the work device 30 is used and fields where the work device 30 is not used, for example, fields where work is performed manually. In addition, the work management device 100 corrects the completion area where the target work is completed based on the proportion of non-output work devices included in the work device 30 that do not output position information. Therefore, the user can grasp the progress status of the target work even if the target work includes non-output work devices that do not output position information.

(Modification)
The configuration described in the embodiment is an example, and the configuration can be changed as long as the function is not impaired. For example, in step S110 shown in Fig. 5, the non-target field determination unit 161 may exclude from the non-target fields an area in which work has been performed by one or more working devices 30 during a predetermined period, for example, a cultivation period of a crop for which the target work should be performed. For example, a field that includes a position represented by the position information of the working device 30 during the cultivation period is excluded from the non-target fields.

The non-target field determination unit 161 may also determine non-target fields based on the planned work timing in the field data 300 shown in FIG. 3. For example, the non-target field determination unit 161 may determine a field for which a planned work timing is not registered as a non-target field.

The non-target field determination unit 161 may also determine the timing of the first work, for example planting work, performed in multiple fields based on the work history data 310, and determine the non-target field based on the determined timing of the first work. For example, when the timing of planting work is different, the timing of work performed in the field, for example harvesting work, is different. For this reason, the timing of the target work relative to the timing of the first work is pre-registered in the non-target field determination unit 161. The non-target field determination unit 161 determines whether the target work will be performed in the field based on the timing of the first work performed in the field, the current time, and the timing of the target work relative to the timing of the first work. When the non-target field determination unit 161 determines that the target work will not be performed in the corresponding field, it determines the corresponding field as a non-target field.

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

The equipment work field determination unit 162 may also register in the field data 300 as equipment target fields those fields in which the target work has been performed by the work equipment 30 during a specified period, for example, from one year ago to the present, among the target work performed in the past in each field. The specified 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.

When the extracted information includes an image captured from the sky, the equipment work field determination unit 162 determines whether the area of the field shown in the image shows traces of the movement of the work device 30, such as the traces of a crawler or wheel. When the trajectory of the work device 30 is shown in the area of the field, the equipment work field determination unit 162 registers in the field data 300 that work was performed by the work device 30 in that field.

In step S150 shown in FIG. 5, the progress amount determination unit 180 corrects the area of the completed area when the work device 30 includes a non-output work device that does not output positioning information, but the area of the target area may also be corrected. For example, the progress amount determination unit 180 multiplies the target area determined by the target area determination unit 160 by the device ratio of the number of non-output work devices to the number of all work devices 30, to correct the target area. The progress amount determination unit 180 determines the amount of progress 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 device 100 determines the progress amount for each field group, and outputs progress information representing the determined progress amount for each field group to the terminal 200.

In addition, in step S140, the target area determination unit 160 may add to the target area the areas of fields that are target fields and are not device work fields, and for which the planned work period has passed. In this case, the completed area determination unit 170 similarly adds to the completed area the areas of fields that are target fields and are not device work fields, and for which the planned work period has passed.

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 required 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. Furthermore, 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 display program 330. Furthermore, the work management system 1000 does not include the terminal 200, and may display progress information on an external terminal not included in the work management system 1000.

The order of the flowchart shown in FIG. 5 may be changed as long as it does not impair functionality. For example, the work management device 100 may execute the process of step S110 after the process of step S130, and may execute the process of step S120 after the process of step S130. Furthermore, the process of step S110 and the process of step S120 may be executed only once before the target work is started. In this case, when the work management device 100 acquires location information from the work device 30, it executes the processes of steps S130 to S160.

In addition, information indicating the target field where the target work is to be performed may be input by the user to the input/output device 210 of the terminal 200. 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.

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