Further, the operation information includes information representing, for example, the speed of the work device 30, the steering angle, the engine rotation speed, the ON/OFF status of various clutches, the position information of the work device 30 at each time, and the like. When the working device 30 is a vehicle that pulls a working machine, such as a tractor, the operation information includes the PTO (power take-off) rotation speed when transmitting power to the working machine, the hitch height indicating the attitude of the working machine, and the like. Information such as lift arm angle may also be included.

When a work is performed by the dedicated device 32, the work management device 100 determines a work type representing the type of work performed. Further, once the work type is determined, the work management device 100 estimates the work type of the work performed by the general-purpose device 31 in the field where the dedicated device 32 worked, based on the work plan data 320. Thereby, the work management device 100 can accurately estimate the work type of the work performed by the work device 30.

(Work management system configuration)
The configuration of work management device 100 included in work management system 1000 shown in FIG. 1 will be described.

The device data 300 represents the type of work performed by the work device 30 with respect to the identifier of the work device 30, such as the model and serial number. For example, a plurality of work types are associated with an identifier representing the general-purpose device 31. Furthermore, one work type is associated with the identifier representing the dedicated device 32. For example, "harvest" is associated with an identifier representing a combine harvester. Furthermore, information indicating that one type of work is not specified may be associated with the identifier representing the general-purpose device 31.

For example, as shown in FIG. 2, the work performance data 310 represents the field where the work was performed by the work device 30, the work period representing the period during which the work was performed, and the work type of the work performed. For example, work performance data 310 shown in FIG. 2 indicates that sowing work 400 was performed in field A on May 7th. Further, the work performance data 310 indicates that work was performed in the field A on April 9th and May 2nd, but the work type of the work has not been determined. For example, the work performance data 310 indicates that work was performed by the general-purpose device 31 on April 9th and May 2nd, and the work type of the work is unknown. Further, the work performance data 310 may store operation information output from the work device 30. Further, the work performance data 310 may store information determined from the operation information, for example, information representing the area in which work was performed by the work device 30.

Work plan data 320 shown in FIG. 1 represents a work schedule to be performed by work device 30 in one or more fields. For example, as shown in FIG. 3, the work plan data 320 represents the field where the work is scheduled to be performed by the work device 30, the work type of the work to be performed, and a planned time indicating the time when the work will be performed. The work plan data 320 shown in FIG. 3 indicates that "plowing" will be performed in the field A three weeks after "cultivation" is performed. Further, the work plan data 320 indicates that "seeding" will be performed in the field A one week after "plowing" is performed. The work plan data 320 indicates that "weeding and spraying" will be performed in field A three weeks after "seeding" is performed. The work plan data 320 may include information representing the area of the field where the work is performed by the work device 30.

The computing device 120 shown in FIG. 1 executes the work management program 330 and is used for various data processing to estimate the work type of the work performed by the general-purpose device 31. For example, the arithmetic device 120 includes a central processing unit (CPU).

By reading and executing the work management program 330, the computing device 120 stores the data storage section 150, the period determining section 160, the dedicated device determining section 170, the type estimating section 180, and the output section, as shown in FIG. 190. The data storage unit 150 stores device data 300, work performance data 310, and work plan data 320. Furthermore, the data storage unit 150 determines the field where the work was performed by the work device 30 based on the operation information of the work device 30. The period determination unit 160 determines the work period in which the work device 30 performed the work based on the operation information of the work device 30. The dedicated device determination unit 170 determines whether the working device 30 that performed the work is the dedicated device 32 based on the device data 300 and the operation information. The type estimation unit 180 estimates the work type of the work performed by the work device 30 based on the work period of the work device 30. The output unit 190 outputs work information representing the estimated work type.

Next, the configuration of the terminal 200 will be explained. As shown in FIG. 1, the terminal 200 includes an input/output device 210, an arithmetic device 220, a communication device 230, and a storage device 240. Terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the arithmetic unit 220 to execute processing is input to the input/output device 210 . In addition, the input/output device 210 outputs the results of processing performed by the arithmetic 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 computing device 220. Further, the signal generated by the arithmetic device 220 is transferred 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, such as a display program 340, for displaying work information acquired from the work management device 100. The storage device 240 is used as a non-transitory tangible storage medium that stores the display program 340. The display program 340 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.

By reading and executing the display program 340, the arithmetic device 220 cooperates with the input/output device 210 to realize the display section 250 as shown in FIG. The display unit 250 acquires work information from the work management device 100 and displays the acquired work information.

(Operation of work management device)
When the computing device 120 of the work management device 100 receives the operation information from the work device 30, it reads and executes the work management program 330. By executing the work management program 330, the computing device 120 executes the processing shown in FIGS. 5A and 5B, which is a work management method.

In step S110, the data storage unit 150 executed by the arithmetic device 120 determines the field where the working device 30 worked based on the operation information of the working device 30. For example, the data storage unit 150 determines the field worked by the working device 30 based on the position information included in the operation information. For example, the data storage unit 150 determines the field including the position represented by the position information as the field worked by the working device 30. Note that information representing the field area is stored in the work plan data 320, for example.

In step S120, the period determination unit 160 determines the work period in which the work device 30 performed the work based on the operation information of the work device 30. For example, the period determination unit 160 determines the period from the first measurement time to the last measurement time as the work period in the position information representing the position included in the field. The period determining unit 160 may determine the start time when the engine of the work device 30 starts and the stop time when the engine stops based on the position information, and determine the period from the start time to the stop time as the work time.

In step S130, the dedicated device determination unit 170 determines whether the work device 30 that performed the work is the dedicated device 32, based on the device data 300 and the operation information of the work device 30. For example, the dedicated device determination unit 170 extracts the identifier of the working device 30 that outputs the operating information from the operating information of the working device 30. The dedicated device determination unit 170 searches the device data 300 for the work type corresponding to the extracted identifier. When the searched work type is one, the dedicated device determination unit 170 determines that the work device 30 that performed the work is the dedicated device 32. When the work device 30 is the dedicated device 32, the process moves to step S140. When the work device 30 is not the dedicated device 32, the process moves to step S210 shown in FIG. 5B.

In step S140, the type estimating unit 180 determines the work type of the first work representing the work performed by the work device 30, specifically the dedicated device 32, based on the device data 300. The type estimating unit 180 determines the work type retrieved in step S130 as the work type of the first work performed by the dedicated device 32. For example, as shown in FIG. 2, when the dedicated device 32 that only performs "seeding" works in field A on May 7th, the type estimating unit 180 performs "seeding" on field A on May 7th. This is determined as the work type of the work performed at A.

In step S150, the type estimation unit 180 estimates the work type of the undetermined second work based on the work plan data 320. For example, the type estimating unit 180 first extracts the second work whose work type is undetermined from the work performance data 310. In the example shown in FIG. 2, the type estimating unit 180 extracts the work on May 2nd and the work on April 9th as the second work for which the work type has not been determined.

Next, the type estimation unit 180 acquires the relationship between the work period of the first work whose work type was determined in step S140 and the work period of the extracted second work whose work type has not been determined, based on the work performance data 310. do. For example, the type estimating unit 180 determines the difference and order between a first work period in which a first work whose work type has been determined is performed and a second work period in which a second work whose work type has not been determined is performed. . For example, in the example shown in FIG. 2, the type estimation unit 180 indicates that the second work on May 2 was performed five days before the first work on May 7, for which the work type was determined. Get information. The type estimating unit 180 also acquires information indicating that the second work on April 9th was performed 28 days before the first work on May 7th for which the work type was determined.

Next, the type estimating unit 180 determines the type of work to be performed based on the work plan data 320, the determined work type of the first work, and the relationship between the work period of the first work and the undetermined work period of the second work. 2. Estimate the work type of the work. For example, the type estimation unit 180 determines, in the work plan data 320, the second work of the second work for the first work period of the first work with respect to the planned time when the determined work type of the first work is scheduled to be performed. The work type of the work corresponding to the period relationship is determined as the work type of the second work. For example, the type estimating unit 180 extracts the determined work type of the first work, such as "seeding", from the work plan data 320 shown in FIG. 3 . The type estimating unit 180 determines the work type of the work corresponding to the relationship of the work period of the second work to the work period of the first work with respect to the planned time of the work type "seeding" of the first work. Determine as the type. For example, the type estimating unit 180 selects the work type of the work that is closest to the relationship of the work period of the second work to the work period of the first work with respect to the planned time of the work type "seeding" of the first work. This is determined as the work type.

In the example shown in FIG. 2, the relationship between the work period of the first work, sowing work 400, and the work period of the second work, for example, the work on May 2, is five days earlier. Therefore, in the work plan data 320, the type estimating unit 180 calculates, for the work type "seeding" of the first work, the work 5 days ago, which is the relationship between the work period of the second work and the work period of the first work. Extract the applicable work type. In the example shown in FIG. 3, the work type that corresponds to the planning time closest to the five days before the work type "seeding" is "plowing" that corresponds to one week before "seeding". Therefore, the type estimating unit 180 determines "padding" as the work type for the work on May 2nd, as shown in FIG.

Further, the type estimating unit 180 similarly determines the work type of the work on April 9th. The relationship between the work period of the sowing work 400, which is the first work, and the work period of the work on April 9 is 28 days ago. In the example shown in Figure 3, the work type that corresponds to the planning period closest to 28 days before the work type "Sowing" is "Pilling" which is 4 weeks before "Sowing", which is the sum of 1 week and 3 weeks before "Sowing". be. Therefore, the type estimating unit 180 determines "cultivation" as the work type for the work on April 9, as shown in FIG. The type estimating unit 180 may determine the work to be performed on April 9th based on the relationship of the work period of the work on April 9th to the previously determined puddling work 410.

In step S160 of FIG. 5A, the output unit 190 outputs work information representing the determined work type to the terminal 200. The work information may include information representing the position and area of the field where the work was performed by the work device 30. Further, the work information may include information representing a work period in which the work was performed by the work device 30.

In step S170, the display unit 250 of the terminal 200 displays the work information acquired from the work management device 100. For example, the display unit 250 displays the type of work performed by the work device 30 on the input/output device 210. Further, the display unit 250 may display an image showing on a map the field where the work was performed by the work device 30 and the type of work performed by the work device 30. The display unit 250 may further display the work period in which the work was performed by the work device 30.

When it is determined in step S130 that the work device 30 does not correspond to the dedicated device 32, in step S210 shown in FIG. Determine whether the work type exists. When the determined work type exists in the work performance data 310, the type estimation unit 180 executes the process of step S220. When the determined work type does not exist in the work performance data 310, the process moves to step S230.

For example, as shown in FIG. 7, it is assumed that the data storage unit 150 of the work management device 100 has acquired operation information regarding the work on May 28th. In this case, in the work performance data 310, there are sowing work 400, plowing work 410, and plowing work 420 as determined work types. Therefore, the type estimation unit 180 executes the process of step S220 shown in FIG. 5B.

In step S220, the type estimating unit 180 estimates the work type of the work performed by the work device 30 based on the work plan data 320, similar to the process in step S150. For example, first, the type estimating unit 180 determines, based on the work performance data 310, the first work period of the first work for which the work type has been determined, and the second work period of the second work performed by the work device 30. Get a relationship with. For example, in the example shown in FIG. 7, the sowing work 400 for which the work type has been determined is performed on May 7th, and the work by the work device 30 is performed on May 28th, so the work period of the second work is In contrast, the first task was performed 21 days ago. Therefore, the type estimation unit 180 obtains that the second work is being performed 21 days after the first work, as the relationship between the first work period of the first work and the second work period of the second work. .

Next, the type estimating unit 180 calculates the type of work based on the work plan data 320, the determined work type of the first work, and the relationship between the first work period of the first work and the second work period of the second work. , estimate the work type of the second work. For example, the type estimating unit 180 extracts "seeding" as the determined work type of the first work in the work plan data 320 shown in FIG. 3 . In FIG. 7, the work on May 28th is 21 days after the sowing work 400, so the type estimating unit 180 determines the plan that is closest to the time 21 days after the work type "seeding" in the work plan data 320 shown in FIG. "Weeding and spraying" is extracted as the work type that corresponds to the period. The type estimating unit 180 estimates the extracted "weeding and spraying" as the work type of the work performed on May 28th. In the example shown in FIG. 7, the type estimating unit 180 may determine the work on May 28th based on the relationship of the work period of the work on May 28th with respect to the determined puddling work 410. Further, the type estimating unit 180 may determine the work to be performed on May 28th based on the relationship of the work period of the work on May 28th to the determined tilling work 420.

In step S230 shown in FIG. 5B, the output unit 190 outputs work information representing the work type to the terminal 200, similar to the process in step S160 shown in FIG. 5A.

In step S240, the display unit 250 of the terminal 200 displays the work information acquired from the work management device 100, similar to the process in step S170 shown in FIG. 5A. For example, the display unit 250 displays the type of work performed by the work device 30 on the input/output device 210. Further, the display unit 250 may display an image showing on a map the field where the work was performed by the work device 30 and the type of work performed by the work device 30. The display unit 250 may further display the work period in which the work was performed by the work device 30.

In this manner, the work management system 1000 uses the work plan data 320 to accurately estimate the work type of the work performed by the general-purpose device 31 such as a tractor.

(Modified example)
The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not impede functionality. For example, the operation information of the work device 30 may include information representing whether the work device 30 is a dedicated device 32 as an identifier representing the work device 30. Furthermore, when the work device 30 is a dedicated device 32, the operation information may include information representing the type of work performed by the dedicated device 32. In this case, in step S130 shown in FIG. 5A, the dedicated device determining unit 170 determines that the working device 30 is the dedicated device 32 when the identifier of the working device 30 included in the operation information indicates the dedicated device 32. Further, in step S140, the type estimating unit 180 determines the work type represented by the identifier of the work device 30 included in the operation information as the work type of the work performed by the work device 30.

The device data 300 shown in FIG. 1 may store information that associates the identifier of the dedicated device 32 that performs work in the field with the type of work performed by the dedicated device 32. For example, device data 300 may not include information regarding general-purpose device 31. In this case, in step S130 shown in FIG. 5A, the dedicated device determination unit 170 determines that when the identifier of the working device 30 represented in the operation information is included in the device data 300, the working device 30 that performed the work in the field is a dedicated device. 32. Further, when the identifier of the working device 30 represented in the operation information is not included in the device data 300, the dedicated device determination unit 170 determines that the working device 30 that performed the work in the field corresponds to the general-purpose device 31.

Further, the device data 300 may store information indicating whether or not the working device 30 corresponds to the dedicated device 32 in association with the identifier of the working device 30. In this case, in step S130 shown in FIG. 5A, the dedicated device determination unit 170 determines that when the identifier of the working device 30 represented in the operation information represents the dedicated device 32 in the device data 300, the working device 30 corresponds to the dedicated device 32. Then, it may be determined.

In step S150 shown in FIG. 5A, the type estimating unit 180 calculates the second work based on the order of the work as the relationship between the work period of the first work whose work type has been determined and the work period of the second work whose work type has not been determined. The work type of the work may be estimated. For example, in the example shown in FIG. 2, the type estimating unit 180 determines the work type of the work on April 9th and the work type of the work on May 2nd based on the order of the work expressed in the work plan data 320. It may be estimated that For example, in field A, the work on May 2nd corresponds to the work immediately before the sowing work 400 on May 7th. Further, the work on April 9th corresponds to the work two steps before the sowing work 400 on May 7th. In the example shown in FIG. 3, the work type of the work immediately preceding the "seeding" work corresponds to "plowing". For this reason, the type estimating unit 180 determines "padding" as the work type for the work on May 2nd. Furthermore, the work type of the second work before the "seeding" work corresponds to "cultivation". Therefore, the type estimating unit 180 determines "cultivation" as the work type for the work on April 9th. Similarly, in step S220 shown in FIG. 5B, the type estimating unit 180 calculates the relationship between the work period of the first work for which the work type has been determined and the work period of the second work performed by the work device 30. The work type of the second work may be estimated based on the order of the work.

The work plan data 320 shown in FIG. 1 may represent a scheduled period, for example, a scheduled date, as a scheduled work to be performed by the working device 30 in one or more fields. In this case, in step S150 shown in FIG. 5A, the type estimation unit 180 estimates the work type of the second work based on the work plan data 320 and the undetermined work period of the second work. For example, the type estimation unit 180 estimates the work type of the second work based on the scheduled period that is closest to the undetermined work period of the second work among the scheduled periods stored in the work plan data 320. For example, the type estimating unit 180 extracts the scheduled period closest to the undetermined work period of the second work, and estimates the work type of the work scheduled to be performed in the scheduled period in the work plan data 320 as the work type of the second work. do. Similarly, in step S220 shown in FIG. 5B, the type estimating unit 180 may estimate the work type based on the work plan data 320 and the work period of the work performed by the work device 30.

Further, the work plan data 320 may represent a cultivation calendar according to the crops to be cultivated and the cropping type, as shown in FIG. 8, as the scheduled period of work. For example, the cropping type includes information such as the cropping type name of the cultivated crop (for example, spring planting, summer planting, etc.), crop type, variety (early maturing, middle maturing, late maturing), cultivation cycle, cultivation method, and the like. The example shown in FIG. 8 represents a cultivation calendar when "crop A" is cultivated using "crop type A." This cultivation calendar indicates that tillage is carried out between late March and mid-April. Furthermore, the cultivation calendar indicates that puddling is performed from mid-April to the beginning of May, and sowing is performed from the beginning of May to the end of May. Furthermore, the cultivation calendar indicates that weeding and spraying will be performed from the beginning of June to the beginning of July.

When the work plan data 320 represents a cultivation calendar, in step S150 shown in FIG. 5A, the type estimating unit 180 estimates the work type of the second work based on the cultivation calendar and the undetermined work period of the second work. You may. For example, the type estimating unit 180 determines the work type of the work to be performed during the work period of the undetermined second work in the cultivation calendar as the work type of the second work. April 9th, when the work was performed in the example shown in FIG. 2, corresponds to the time when plowing is performed in the cultivation calendar shown in FIG. Therefore, the type estimating unit 180 estimates the work type of the work performed on April 9th as "cultivation". Furthermore, May 2nd, when the work was performed in the example shown in FIG. 2, corresponds to "plowing" and "seeding" in the cultivation calendar shown in FIG. 8. Since the sowing work 400 was performed on May 9th, the type estimating unit 180 estimates the work type of the work performed on May 2nd as "plowing". In this case, the crops and cropping types to be cultivated in each field may be input by the user. Similarly, in step S220 shown in FIG. 5B, the type estimating unit 180 may estimate the work type based on the cultivation calendar and the work period of the work performed by the work device 30.

Further, the work plan data 320 may represent a work schedule to be performed by the work device 30 depending on the crop. In this case, in step S150 shown in FIG. 5A and step S220 shown in FIG. Extract work schedule. Based on the extracted work schedule, the type estimation unit 180 estimates the work type of the undetermined second work.

Further, in step S150 shown in FIG. 5A, the type estimating unit 180 may estimate the work type of the undetermined second work using a plurality of methods. For example, the type estimation unit 180 estimates one or more work types of the undetermined second work using a plurality of methods, and estimates the work type that is estimated the most as the work type of the second work. Further, the type estimating unit 180 estimates one or more work types of the undetermined second work, and estimates one work type as the work type of the second work from the one or more work types using an arbitrary method. Good too. Similarly, in step S220 shown in FIG. 5B, the type estimating unit 180 may estimate the work type of the work performed by the work device 30 using a plurality of methods.

Furthermore, in step S170 shown in FIG. 5A and step S240 shown in FIG. The displayed second work type may be distinguished from the second work type. In this case, the user may input a confirmation operation to confirm the second work type into the input/output device 210 of the terminal 200. When the confirmation operation is input, the display unit 250 outputs confirmation information indicating that the second work type has been confirmed to the work management device 100. Based on the confirmation information, the type estimating unit 180 of the work management device 100 stores information indicating that the corresponding work type has been confirmed in the work performance data 310.

Further, the field information regarding the field where the work was performed by the work device 30 may be input by the user to the input/output device 210 of the terminal 200. In this case, the display unit 250 of the terminal 200 outputs field information to the work management device 100. The data storage unit 150 of the work management device 100 may determine the field where the work was performed by the work device 30 based on the field information.
