Detailed Description

(First embodiment)

The work support system 1 of the present embodiment will be described with reference to the drawings. In the present embodiment, as shown in fig. 1, a work support system 1 includes a work support device 10 and a terminal device 20. The work support device 10 and the terminal device 20 are communicably connected to each other via a network NT to a work device 30 that performs work in each of the plurality of fields F. Examples of the network NT include the internet and an intranet.

In order to assist a user who performs a job in field F1, for example, job assist system 1 of the present embodiment determines a common field in which agricultural work should be performed on a schedule common to field F1, based on schedule information indicating a schedule in which work device 30 performed a job in the field. The common field includes, for example, one or more fields F (for example, field F2, field F3, … …, field Fn) to which agricultural work should be performed in the same cultivation type as field F1. The work support system 1 displays a support image showing the number of fields in which work is performed in common in one or more previous divided periods. For example, the one or more divided periods may be periods obtained by dividing the current time by a predetermined reference until a predetermined time (for example, 5 days ago). In the present embodiment, the divided period includes each period from 0 to 24 hours of the present day, the previous day, the 2 day previous, … … days previous, and the 5 day previous, which are obtained by dividing the period from the present day to the predetermined period by the reference time (for example, at 0 am). The division period may be a section divided in the morning and afternoon. Alternatively, the divided period may be a period obtained by dividing the period from the current time to a predetermined period (for example, one month) before every predetermined time (for example, 3 days). The division period may be, for example, a plurality of sections obtained by dividing a period including the current time, a month, or a period from the beginning of the year to the present time by a predetermined criterion (for example, daily or weekly).

The user who has observed the auxiliary image displayed by the work support system 1 can determine when the user should perform work by himself or herself based on the number of jobs on the field F where the agricultural work should be performed on the common schedule, for example, when the user performed work on a large number of common fields before 2 days and before 1 day, and so on. In the present embodiment, the work support system 1 displays the divided period in which the work is performed in the good field (for example, field F2) having excellent performance of the past agricultural work so as to be distinguishable from the divided period in which the work is not performed in the good field. Therefore, the user who observes the auxiliary image displayed by the work support system 1 can determine the time when he/she should work based on the period of time during which the work is divided in the good land which can be standardized among the common lands in which the agricultural work should be performed on the common schedule. In this way, the work support system 1 can efficiently support an operator who performs a work in a field.

The construction of the work support system 1 will be described. As shown in fig. 2, the work support apparatus 10 included in the work support system 1 includes an input/output apparatus 12, a computing apparatus 14, a communication apparatus 16, and a storage apparatus 18. The work support device 10 is, for example, a computer including a cloud, or a server device.

Information for the processing performed by the arithmetic device 14 is input to the input/output device 12.

The communication device 16 is connected to the network NT so as to be communicable, and communicates with devices (e.g., the working device 30 and the terminal device 20) external to the work support device 10 via the network NT. The communication device 16 transmits information acquired from the plurality of work devices 30 and the terminal device 20 to the arithmetic device 14. The information generated by the arithmetic device 14 is transmitted to either or both of the working device 30 and the terminal device 20. The communication device 16 includes various interfaces such as NIC (Network INTERFACE CARD: network interface card) and USB (Universal Serial Bus).

The storage device 18 serves as a non-transitory storage medium (non-transitory tangible storage medium) that stores these data and commands. The program P1 may also be provided as a computer program product (computer program product) recorded on the computer-readable storage medium M1. Alternatively, the storage medium M1 may be a storage device of an external server storing the program P1. In this case, the data including the program P1 can be provided as a computer program product downloadable from a server.

The arithmetic device 14 reads and executes a program P1 including a command and data for assisting the user operation of the working device 30 from the storage device 18. The arithmetic device 14 includes, for example, a central processing unit (CPU; central Processing Unit) and the like. The arithmetic device 14 reads and executes the program P1 to realize the functional units of the work support device 10 described later.

As shown in fig. 3, the terminal device 20 includes an input/output device 22, a computing device 24, a communication device 26, and a storage device 28. Examples of the terminal device 20 include a computer, a tablet computer, and a mobile phone. Information for the operation device 24 to execute display processing of a screen based on the output information is input to the input/output device 22. The input/output device 22 outputs the result of the processing performed by the arithmetic device 24. The input-output device 22 includes various input devices and output devices including, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

The communication device 26 is connected to the network NT so as to be capable of communication, and performs communication with external devices (for example, the work support device 10, the work device 30, and the like) via the network NT. The communication device 26 transmits information acquired from the work support device 10 to the arithmetic device 24. The information generated by the arithmetic unit 24 is transmitted to the work support device 10. The communication device 26 includes various interfaces such as a transceiver, NIC (Network INTERFACE CARD), and USB (Universal Serial Bus) for wireless communication such as a wireless LAN (Local Area Network: local area Network), a cellular Network, and the like.

The storage device 28 stores various data for displaying a screen based on the output information acquired from the work support device 10, for example, the program P2. The storage device 28 serves as a non-transitory storage medium (non-transitory tangible storage medium) storing the program P2. The program P2 may also be provided as a computer program product (computer program product) recorded on the computer-readable storage medium M2. Alternatively, the storage medium M2 may be a storage device of an external server storing the program P2. In this case, the program P2 can be provided as a computer program product downloadable from a server.

The arithmetic device 24 reads and executes the program P2, and as described later, cooperates with the input/output device 22 to realize a display function or the like of a screen based on the output information from the work support device 10.

In the present embodiment, work implement 30 shown in fig. 1 is an agricultural machine that performs a work in a field. Examples of the working device 30 include a tractor that pulls various working machines such as a harvester, a cultivator, and a fertilizer applicator, and a seedling transplanting machine such as a rice transplanter, and a vehicle that performs agricultural work in a field. Examples of the equipment other than the working device 30 include agricultural equipment that can fly such as an unmanned aerial vehicle that performs agricultural work. The working device 30 includes, for example, a positioning device that repeatedly acquires its own position and the current time (for example, date, time, minute, second, etc.) using a positioning system such as a global positioning satellite system (GNSS). The positioning device of the present embodiment measures the position and time of the working device 30 at a predetermined cycle (for example, every 5 seconds), for example. The working device 30 includes a sensor that measures an operating state (for example, a speed, an engine speed, an engaged/disengaged state of a clutch, and an amount of pesticide and fertilizer spread at each time) in the field. The work device 30 outputs operation information including position information indicating a position and a time at which the work is performed in the field and operation information indicating a measured operation state at the time to the work support device 10.

The physical structure shown in fig. 2 and 3 allows the work support device 10 and the terminal device 20 to realize the functional units shown in fig. 4. As an example, the arithmetic device 14 of the work support apparatus 10 executes the program P1 to realize the functions of the information acquisition unit 110, the cultivation type estimation unit 120, the common determination unit 130, the aggregate generation unit 140, the quality determination unit 150, the quality generation unit 160, the output unit 170, and the information storage unit 180.

The information storage unit 180 stores information necessary for the later-described processing including, for example, the field information D1, the schedule information D2, the cultivation type template information D3, the actual result information D4, and the operation information D5 in advance. The information storage unit 180 may temporarily store information acquired or generated by the information acquisition unit 110, the cultivation type estimation unit 120, the common determination unit 130, the aggregate generation unit 140, the quality determination unit 150, and the quality generation unit 160.

The field information D1 includes, for example, information indicating the geographical position and the range of each field F of the plurality of fields F to be processed by the work support system 1. The field information D1 may include information indicating the entire area of each field F of the plurality of fields F.

For example, as shown in fig. 5, the schedule information D2 stores, for each field F, information indicating the time when any one of the plurality of work devices 30 has performed a work, and information indicating the type of work performed. In the example of fig. 5, the schedule information D2 associates and stores "job ID" indicating information for specifying the job, "field ID" indicating the field in which the job is performed, "job date" indicating the date on which the job is performed, and "job type" indicating the type of the job. In the present embodiment, the information storage unit 180 stores schedule information D2 of each field F, and the schedule information D2 includes, for example, information of a job from the start to the end of a one-time cultivation period including a period from the start of the preparation of the agricultural field to the end of harvesting for crops currently being cultivated.

For example, as shown in fig. 6, the cultivation type template information D3 stores information indicating typical work periods of agricultural works to be performed in the field F for a plurality of cultivation types. One cultivation type corresponds to a cultivation method in which "spinach" is planted in a certain period by a certain method, such as "inhibited cultivation" for "early spring sowing, summer and autumn harvest". In the example of fig. 6, the cultivation type template information D3 is associated with and stored as "cultivation type ID" indicating information for specifying a cultivation type, "crop" indicating a name of a crop, "details" indicating specific contents of a cultivation type such as a cultivation time and a cultivation method, "job type" indicating a type of job to be executed for each cultivation type, and "job period" indicating a typical period in which each job type should be executed.

In the example of fig. 6, the work such as "cultivated land", "flat ground" and "sowing" is required for the cultivation type having "cultivation type ID" ID01", the" crop "is" soybean ", the" detail "is" spring sowing ", and typically, the work is performed at the time indicated by each cell of the" work period ". On the other hand, in the cultivation type in which the "cultivation type ID" is "ID02", the "crop" is "spinach", the "detail" is "spring sowing", and the operations such as "cultivated land", "flat ground" and "sowing" are required, and typically, the operations are performed at the time indicated by each cell of the "operation period".

The actual performance information D4 shown in fig. 4 stores, for example, information indicating actual performance of work on a plurality of fields F. In the present embodiment, the actual performance information D4 includes information on the actual performance of the past harvest amount, such as the harvest amount per unit area of the previous year, for each of the plurality of fields F.

The operation information D5 shown in fig. 4 is information in which operation information output by the work machine 30 that performs a work in each of the plurality of fields F is stored.

The information acquisition unit 110 shown in fig. 4 acquires information for processing to be described later, such as field information D1, schedule information D2, cultivation type template information D3, actual result information D4, and operation information D5, from the information storage unit 180. Alternatively, the information acquisition unit 110 may acquire the information from the storage device 18, a user input using the input/output device 12, an external server device, the terminal device 20, or the like.

As described later, the cultivation type estimating unit 120 estimates the cultivation type of the crop cultivated in the plurality of fields F shown in the field information D1, based on the schedule information D2 and the cultivation type template information D3.

The common determining unit 130 determines one or more common fields (for example, fields F2 to Fn) that are common to the field F1 to be processed, based on the cultivation type estimated by the cultivation type estimating unit 120, and a schedule of the work to be performed in the plurality of fields F.

As described later, the summary generation unit 140 generates summary information obtained by summing up the number of common fields subjected to the work in one or more divided periods before the current time.

As will be described later, the quality determining unit 150 determines a quality field (for example, field F2) in which past work performance in the common field satisfies a predetermined criterion, based on the performance information D4.

As described later, the quality generation unit 160 generates quality information indicating a period in which a job is performed in the good land among one or more divided periods.

The output unit 170 outputs output information including the summary information generated by the summary generating unit 140 and the excellent information generated by the excellent generating unit 160.

The terminal device 20 executes the program P2 by the computing device 24, and cooperates with the input/output device 22 to realize the display unit 210. The display unit 210 displays an auxiliary image for assisting the job in the field F1 based on the output information. The content of the auxiliary image will be described later.

(Action of work support System)

The work support system 1 performs the processing shown in fig. 7 and 8 by the above-described functional configuration, and displays a support image. For example, the work support device 10 starts the process of fig. 7 when the time of day becomes a predetermined time (for example, at 0 am). Alternatively, the work support device 10 may start the process of fig. 7 when receiving a user operation for performing the classification process of the field F via the input/output device 12.

First, in step S1002, the information acquisition unit 110 of the work support apparatus 10 acquires the field information D1 and the operation information D5. For example, the information acquisition unit 110 acquires the field information D1 from the information storage unit 180. The field information D1 is stored in the information storage unit 180 in advance by a user operation of inputting information indicating the field F to be processed, for example, using the input/output device 22. The information storage unit 180 stores the operation information as the operation information D5 in a concentrated manner each time the operation information is output from the work device 30 that has performed the work in each field F.

Next, in step S1004, the information storage section 180 generates schedule information D2 based on the field information D1 and the operation information D5. For example, if the operation information D5 includes operation information indicating a position included in the geographical range of each field F indicated by the field information D1, the information storage unit 180 recognizes that a job is performed on the field F on the date when the operation information is located. Then, the information storage unit 180 registers information indicating the field F as "field ID" and information indicating the date of operation as "date of operation" in the schedule information D2. The information storage unit 180 determines, for example, the type of agricultural work that has been performed on the work day based on user input, and stores information indicating the type of work in the "type of work". For example, the terminal device 20 receives a user input indicating the type of a job in each field F that the user has performed on that day, using the input/output device 22. The information storage unit 180 obtains information indicating the type of the job input by the user, in addition to the operation information of the working device 30 that has performed the job in each field F. Then, when the schedule information D2 is registered based on the operation information, the information storage unit 180 registers information indicating the type of the job that has been performed on the field F on that day. The information storage unit 180 performs such registration processing each time the operation information is output from the working device 30, and stores the schedule information D2 in the information storage unit 180 in advance. The information storage unit 180 may acquire the schedule information D2 from an external server that collects the operation information from the work implement 30.

Next, in step S1006, the cultivation type estimating unit 120 of the work support apparatus 10 estimates the cultivation types of the plurality of fields F based on the schedule information D2 and the cultivation type template information D3. For example, the cultivation type estimating unit 120 compares the "job period" of the "job type" of the cultivation type registered in the cultivation type template information D3 with the job date on which the job of the type corresponding to the "job type" is performed as shown in the schedule information D2, and estimates the cultivation type of each field F. As an example, when all of the work days of a certain field F shown in the schedule information D2 are included in the "work period" of the "work type" corresponding to a certain work type registered in the work type template information D3, the work type estimating unit 120 estimates the work type as the work type of the field F. When the work date of a certain type of work in a certain field F indicated by the schedule information D2 does not completely coincide with the "work period" of the "work type" corresponding to any of the cultivation types registered in the cultivation type template information D3, the cultivation type estimating unit 120 obtains, for each cultivation type, an error of a date closer to the work date among the time periods (earliest or latest date) of the work date and the "work period" for each work date not included in the "work period". Then, the cultivation type estimating unit 120 estimates the cultivation type of the field F as the cultivation type of which the cumulative total of the differences between the work day and the work period, which are not included in the "work period", is the smallest.

Then, the information storage unit 180 temporarily stores information on the type of cultivation estimated for each field F, and the work support apparatus 10 ends the process of fig. 7.

The job support device 10 starts the process of fig. 8 based on a user input for displaying the auxiliary image of the job of the field F1 to be supported, for example. In the present embodiment, first, the terminal device 20 receives a user input for displaying an auxiliary image of the field F1 using the input/output device 22. Examples of the user input for displaying the auxiliary image of the field F1 include clicking the field F1 on a screen on which the map images of a plurality of fields F are displayed by the input/output device 22 of the terminal device 20. When receiving the information indicating the user input output from the communication device 26 of the terminal device 20, the job support device 10 starts the process of fig. 8.

In the process of fig. 8, in step S2002, the common determining unit 130 of the work support apparatus 10 determines a common field of the fields F1 to be processed. For example, the common determining unit 130 determines, as a common field of the fields F1, a field F common to the field F1 of the treatment target and the type of cultivation estimated in step S1006 in fig. 7 among the fields F shown in the field information D1.

Next, in step S2004, the summary generating unit 140 generates summary information on the jobs in the common field. For example, the summary generating unit 140 sums up the number of fields F, on which the job has been performed, in the common field determined in step S2002 for each of the one or more divided periods based on the schedule information D2. For example, when the divided period is set for each day before the current day to 5 days, and the fields F2 to Fn are determined as the common fields, the summary generating unit 140 generates summary information in which the number of fields in which the operations are performed on each day before the current day to 5 days among the fields F2 to Fn are summarized. In the present embodiment, the summary generating unit 140 sums up the number of fields in which the jobs have been performed so as not to distinguish the types of jobs performed during each of the divided periods in the processing of step S2004. The aggregate generating unit 140 may be configured to aggregate the fields F1 to Fn having the same cultivation type as the field F1 itself.

Next, in step S2006, the quality determination unit 150 determines a quality field based on the performance information D4. For example, the quality determining unit 150 determines a field (for example, field F2) having the most excellent work performance shown in the shared field performance information D4 determined in step S2002 as a good field. As an example, when the actual performance information D4 includes information on the harvest amount per unit area of each field F of the previous year as an index value indicating the actual performance, the quality determination unit 150 may determine the field F1 having the highest harvest amount per unit area as the quality field. Alternatively, the quality determination unit 150 may determine all of the common fields in which the work performance shown in the performance information D4 satisfies the predetermined condition as the quality fields.

Next, in step S2008, the quality generation unit 160 generates quality information indicating a period of time during which the job has been performed in the good land determined in step S2006, among the one or more divided periods. For example, when the schedule information D2 shows that the work is performed in the field F2 that is the good field on 3 days, the good generation unit 160 generates good information indicating that the work is performed in the good field during the period of 3 days before the first day. In the case where there are a plurality of excellent fields, the excellent information may be information on the number of excellent fields in which the work is performed for each section period.

Next, in step S2010, the output unit 170 outputs output information including the summary information generated in step S2004 and the excellent information generated in step S2008. For example, the output unit 170 outputs output information to the terminal device 20 using the communication device 16.

Next, in step S2012, the display unit 210 of the terminal device 20 displays the auxiliary image based on the output information. For example, as shown in fig. 9, the auxiliary image includes information indicating one or more divided periods (day to 5 days ago) and information TI indicating the number of common fields (fields F2 to Fn) in which the work is performed in each divided period. As an example, the display unit 210 classifies the respective divided periods by the number of the fields F subjected to the work in the divided period based on the summary information. For example, classified into: the number of field F subjected to the work is more than a predetermined first threshold (for example, 5) divided periods, less than a predetermined second threshold (for example, 2) divided periods, and divided periods between the first threshold and the second threshold. Then, the display unit 210 displays information indicating how many fields the work has been performed in each divided period in a recognizable manner. In the example of fig. 9, as the information TI indicating the number of common fields in which the work is performed on the day, the display unit 210 marks the "small" indicating that the number of fields F in which the work is performed is small, the "large" indicating that the number of fields F is large, and the "medium" indicating that the fields F are in the middle of the two, on the auxiliary image below the circle indicating the divided period, and displays the mark.

In the example of fig. 9, the auxiliary image includes information EI that enables identification between a period in which the work is performed in the good field (for example, field F2) and a period in which the work is not performed in the good field. For example, the display unit 210 may display "correspondingto-! "tag as information EI.

In this way, the job support system 1 displays the support image indicating the number of fields F to be worked in each of the one or more divided periods among the common fields to be worked on the schedule common to the fields F1 to be processed. Therefore, the user acting as the job in the field F1 can determine when the user should perform the job on the basis of the information on the progress degree of the job in the fields F2 to Fn in which the agricultural jobs should be performed on the common schedule. Further, the work support system 1 displays a support image including information EI indicating a period of time during which the work is divided in the field F2, which is a good field. Therefore, the user can perform the work of the field F1 with reference to the work schedule of the other user who achieves excellent work efficiency. Therefore, the work support system 1 can efficiently support the work in the field F.

(Modification)

The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not hinder the function.

For example, the common determining unit 130 of the work support system 1 according to the above embodiment estimates the cultivation type of each field F based on the schedule information D2 and the cultivation type template information D3 generated based on the operation information D5, and determines the field F corresponding to the common cultivation type as the common field. However, the present invention is not limited thereto, and the common determining unit 130 may determine the common field by classifying the plurality of fields F based on the schedule information D2 without using the cultivation type template information D3. As an example, the common determination unit 130 classifies the plurality of fields F into a plurality of groups each including one or more fields to be operated according to the common schedule, based on the similarity of the operation days shown in the schedule information D2. For example, the common determination unit 130 prepares n-dimensional data indicating the operation status of the first to the m-th days in the present year. The n-dimensional data are for example like field Fk: { d1, d2, d3, … …, dm } includes the value d1 corresponding to the first day of the work of the field Fk, the values d2, … … corresponding to the second day of the work, and the value dm corresponding to the mth day of the work. Each of the values d1 to dm takes a value of 1 when the work is performed on the field Fk on the corresponding date, and takes a value of 0 when the work is not performed. The common determining unit 130 may perform unsupervised clustering on the n-dimensional data of each of the fields F1 to Fn so as to classify the data having high similarity between the data into the same rank, and determine the fields F classified into the common rank as the common fields.

For example, the common determination unit 130 may determine the common field based on the schedule information D2 of the same period before the last year, instead of the schedule information D2 showing the schedule of the work in the current season. In this modification, even when the work on the current season of the field F is hardly performed, the common field of the field F1 can be determined based on the previous actual results.

In the above embodiment, the actual performance information D4 used by the excellent determining unit 150 includes information on the harvest amount per unit area of each field F of the previous year as an index value indicating the actual performance of the work. However, the performance information D4 is not limited to this, and may include quality information (for example, information indicating sugar level or acidity of crops produced in the field F) of each field F and sales per unit area as index values. Alternatively, the performance information D4 may include information indicating the field F where the operator of the fields F1 to Fn performs the work by the operator selected for the excellent operator. For example, a good operator may be an operator who is selected by the operator as an operator who harvest more crops of higher quality than other operators. In this case, the quality determination unit 150 may determine the field F in which the quality worker works as indicated by the performance information D4 as the quality field in step S2006.

In the above embodiment, the information storage unit 180 determines the "job type" of the schedule information D2 based on the user input. However, the present invention is not limited to this, and the information storage unit 180 may estimate the type of the job indicated by the "job type" based on the operation information. For example, the information storage unit 180 may store a machine learning model that learns using teacher data including operation information of the work device 30 that performs a known type of work and data indicating the type of work. The information storage unit 180 may also estimate the type of the job on each day in each field F by inputting the operation information on each job day of the job device 30 that has performed the job in each field F in the operation information D5 into the machine learning model. Or, for example, when the working device 30 is a tractor, the working device 30 outputs the operation information including information indicating the type of the working machine (for example, a harvester, a cultivator, or a fertilizer applicator) towed by the tractor, and outputs the operation information including information indicating the product model. The information storage 180 estimates the type of the work performed by the work device 30 based on the information indicating the type of the work machine and the type of the work device 30 included in the operation information, and stores the estimated type of the work in the "type of work".

The cultivation type estimating unit 120 may estimate the cultivation type of each field F by a process different from the process described in step S1006 in fig. 7. For example, the cultivation type estimating unit 120 may estimate the cultivation type of the field F using the machine learning model in step S1006. As an example, the information storage unit 180 may store a machine learning model that learns using teacher data including a known cultivation type and operation information of the work implement 30 that performs work on the cultivation type. Then, in step S1006, the cultivation type estimating unit 120 inputs the operation information of the work machine 30 that has performed the work on each field F into the machine learning model, and estimates the cultivation type from the obtained output.

In the above-described embodiment, in step S2004 in fig. 8, the work support system 1 performs processing without distinguishing the type of work of the work performed in each field F. However, the job support system 1 may perform the process of generating the summary information in consideration of the job type. For example, the summary generating unit 140 determines the type of job to be performed next in the field F1 to be processed in step S2004 in fig. 8. At this time, the summary generating unit 140 determines, based on the schedule information D2, the job of the type closest to the "job period" among the jobs that have not yet been performed in the field F1, among the plurality of "job types" to be performed in the field F1, which are indicated by the cultivation type template information D3, as the job type to be performed next. Then, in step S2004, summary information may be generated that summarizes the number of fields F that have performed the determined types of work to be performed next among the common fields (fields F2 to Fn). Similarly, in step S2008, the quality generation unit 160 may determine quality information indicating a period during which the division of the type of work to be performed next is performed in the field F2 that is the good field.

In step S1004, information storage 180 obtains schedule information D2 based on the operation information output from work implement 30. The information storage 180 may store the schedule information D2 based on a user operation. For example, a user who performs a job in each field F inputs information about the fact that the job was performed on that day to the terminal device 20 using the input/output device 22 of the terminal device 20. Then, the terminal device 20 outputs information indicating the field F where the job is performed and information indicating the date when the job is performed to the job support device 10. The information storage 180 may store the schedule information D2 by registering the information in the schedule information D2.

The auxiliary image displayed by the display unit 210 is not limited to the image shown in fig. 9. For example, the auxiliary image displayed on the display unit 210 may further include weather information indicating weather in each divided period. For example, the display unit 210 of the terminal device 20 obtains weather information for each divided period from a server providing the weather information using the communication device 26. The weather information may include, for example, information indicating whether the weather during the section is rainy or sunny, precipitation, maximum air temperature, minimum air temperature, and the like. The display unit 210 may display an auxiliary image including, for example, information indicating an umbrella mark for rain or a sun mark for sun, and digital information indicating precipitation, highest temperature, and lowest temperature, as information indicating each divided period and weather information, which are shown in fig. 9.

In the above embodiment, the work support system 1 generates the aggregated information without considering the geographical position of each field F. However, the present invention is not limited to this, and the job support system 1 may generate the summary information for only the field F located within a predetermined range from the field F1 to be processed. In this case, for example, the common determining unit 130 may determine the common field for all the fields F included in the field information D1 in step S2002 in fig. 8. On the other hand, in step S2004, the summary generation unit 140 may generate summary information for a common field (for example, a common field existing in the same province and city and county as the field F1, a common field existing within a radius D km from the field F1, a common field existing in an arbitrarily set polygonal area (rectangle), or the like) that is geographically near the field F1 based on the field information D1.

As shown in fig. 10, the display unit 210 may display an auxiliary image including information AI indicating geographical information about the periphery of the field F1 to be processed. The display unit 210 may display information AI in which the geographical areas occupied by F2 to Fn, which are common fields, among the plurality of fields F existing within the predetermined distance range (for example, radius d km) are displayed so as to be distinguishable from other areas (for example, in different colors).

As shown in fig. 11, the display unit 210 may display an auxiliary image including the bar chart G1 as information indicating the summary information. In the example of fig. 11, the bar shape indicating the number of fields on each day corresponds to the information TI indicating the number of shared fields on which the work is performed. In the auxiliary image of fig. 11, a bar chart corresponding to the date of the operation performed in the field F2, which is a good field, is displayed in a different color from other bar charts. The bar chart is displayed so as to be distinguishable from the divided period in which no work is performed in the good field (field F2), and thus corresponds to the information EI of fig. 9.

The job support system 1 may generate the second summary information using the field F located outside the predetermined range from the field F1 to be processed as another summary object. In this case, for example, the summary generating unit 140 may generate the second summary information for the common field located in the region different from the field F1 based on the field information D1 in step S2004 in fig. 8. The field to be the second aggregation information may be, for example, a common field located in an administrative division (for example, city or province) different from the field F1, a common field located in a region different from the region including the field F1 in climatic conditions (for example, a plain of a region different from the region to which the field F1 belongs), or a common field located in a region earlier than the region including the field F1 in a job day suitable for the same type of job of the same farming type.

In this case, as shown in fig. 12, the display unit 210 may display an auxiliary image including a bar chart G2 indicating the second summary information in addition to the bar chart G1 of fig. 11. In the example of fig. 12, the bar graph G2 shows the number of fields in which work is performed in one or more divided periods in a common field that is geographically distant from the field F1 to be processed but is common to the cultivation type and the like. In such a modification, the user can compare information indicating the result of the aggregation of the geographically close common field and the common field of different areas, and can prepare a plan of the work in the field F1.

In addition, when a job is performed in one common field in a plurality of divided periods, the summary generating unit 140 of the job support system 1 may generate summary information in step S2004 in fig. 8, considering that a job is performed in the common field in each of the plurality of divided periods. For example, when the work is performed in the field F3 before 3 days, 2 days, and 1 day, the summary generating unit 140 may generate the summary information by counting the number of works performed before 3 days, 2 days, and 1 day.

In the case where the job is performed in a plurality of divided periods in one common field, the summary generating unit 140 of the job support system 1 may generate the summary information in step S2004 in fig. 8, considering that the number of jobs is performed less than once in the plurality of divided periods in which the job is performed in the common field. For example, when the jobs are performed in the same field F in a plurality of divided periods, the summary generating unit 140 may count that the jobs are performed once in total in the field F to generate summary information. As an example, when the work is performed in the field F3 before 3 days, 2 days, and 1 day, the summary generating unit 140 may generate the summary information by counting 1/3 times of the work performed before 3 days, 2 days, and 1 day.

Alternatively, the summary generating unit 140 may generate the summary information by using a value less than 1 obtained based on the area of the entire common field in which the work is performed and the area in which the work is performed in each divided period as the number of works performed in the common field in the divided period. For example, when a job is performed on 1/4 of the entire field F3 before 3 days, the summary generation unit 140 may generate summary information by counting 0.25 times before 3 days as the job is performed on the field F3. In this case, the summary generating unit 140 may determine the work area that has been performed in the divided period based on the position of the work device 30 that has performed the work in the field F in the divided period, as indicated by the operation information D5. As an example, the summary generating unit 140 may determine a convex hull including each position based on the position of the working device 30 that has performed the work in the field F during the division period shown in the operation information D5, and determine the area of the convex hull as the work area for the work division. The summary generating unit 140 may determine the ratio of the determined work area of the field F to the entire area of the field F shown in the field information D1 as a value of 1 or less indicating the number of times of work performed in the work area.

In addition, when obtaining information on the work width of the work implement 30, the summary generating unit 140 may calculate the work area in each divided period based on the travel distance and the work width in the field F. For example, the working device 30 outputs operation information indicating the own work width to the work support device 10. Then, the information storage unit 180 stores the job width of each job device 30 in the operation information D5. In step S2004 in fig. 8, the summary generation unit 140 obtains the distance moved by the working device 30 in the field F in the divided period, based on the position of the working device 30 in the field F in the divided period, among the positions indicated by the operation information D5. Then, the summary generating unit 140 may calculate the ratio of the work area to the entire area of the field F by using, as the work area, a value obtained by multiplying the calculated travel distance by the work width indicated by the operation information D5.
