In the example of fig. 1, the working device 30 is provided with: the work should be performed in a plurality of fields a. Therefore, when the work of the field A1 in the current work is completed, the work device 30 is transported by the transport device 40 and moved toward the field A2 to be subjected to the next work. The conveying device 40 is, for example: a truck or a vehicle capable of transporting the working device 30, such as a tractor that pulls a transport vehicle for transporting the working device 30.

The information storage unit 170 stores: for example, the 1 st operation information D1, the field information D2, the 2 nd operation information D3, and the plan information D4.

The 1 st operation information D1 stores, for example, operation information of the work implement 30 to be processed of the work support system 1 in association with information (for example, "work implement ID") specifying the work implement 30. Here, the operation information of work implement 30 includes: positioning information of work implement 30, and information indicating a work width of work implement 30. When there are a plurality of pieces of positioning information of the working device 30 at the time of working in the field A1, the 1 st operation information D1 is stored in association with the working device ID of the working device 30.

As an example, as shown in fig. 6, the field information D2 is stored in association with information ("field ID") for specifying each field a, information ("area definition information") for indicating the position of the field a, and information ("area") for indicating the area of the field a.

For example, the 2 nd operation information D3 is the latest positioning information among the plurality of positioning information repeatedly positioned by the conveying device 40. When there are a plurality of conveyance devices 40 capable of conveying the work device 30, the 2 nd operation information D3 is stored in such a manner that the operation information of the plurality of conveyance devices 40 is associated with the conveyance device ID.

As shown in fig. 8, the schedule information D4 is stored in association with information ("job ID") for specifying a job to be performed from the current start of the job device 30, information (e.g., "field ID") for specifying a field a in which the job is to be performed, and information (e.g., "job amount") indicating an amount of the job to be performed in the field a. In the present embodiment, the work amount represents: the time required for estimating the work performed in each field a by work implement 30.

The information acquisition unit 110 transmits the acquired information to each functional part such as the time determination unit 120, the object conveyance determination unit 130, and the information storage unit 170.

The time determination unit 120 determines, based on the 1 st operation information D1 and the plan information D4: it is estimated that an estimated end time is required until the work device 30 to be processed ends the work in the field A1 currently performing the work. The time determination unit 120 transmits information indicating the determined estimated end time to the movement output unit 140.

The object conveyance determination unit 130 determines, based on the positions of 1 or more conveyance devices 40 indicated by the 2 nd operation information D3 and the position of the field A1 indicated by the field information D2: the object carrying device 40A that can carry the working device 30 out of 1 or more carrying devices 40 of the terminal device 20 is capable of carrying the working device 30. The object conveyance determination unit 130 transmits information indicating the determined object conveyance device 40A to the movement output unit 140.

The movement output unit 140 outputs movement instruction information indicating that the movement to the field A1 is to be performed, based on the estimated end time determined by the time determination unit 120, to: the terminal device 20 corresponding to the object carrying device 40A determined by the object carrying determination unit 130.

The conveyance destination acquisition unit 150 acquires, based on the plan information D4, a conveyance destination field A2 to which the working device 30 should be conveyed, from among the plurality of fields a. The conveyance destination acquisition unit 150 transmits information indicating the acquired conveyance destination field A2 to the conveyance output unit 160.

The conveyance output unit 160 outputs conveyance instruction information indicating that the conveyance terminal device 20 should be conveyed to the field A2 determined by the conveyance destination acquisition unit 150 to: the terminal device 20 corresponding to the object carrying device 40A determined by the object carrying determination unit 130.

The display unit 210 of the terminal device 20 uses the input/output device 22 to display the movement instruction information output by the movement output unit 140: a screen indicating that the object carrying device 40A should be moved to the field A1. The display unit 210 also displays, based on the conveyance instruction information output by the conveyance output unit 160: a screen showing that work implement 30 should be transported to field A2.

(action of work assistance System 1)

The work support system 1 is configured as described above, and performs the processing shown in fig. 9A and 9B as an example of the work support method, thereby supporting the improvement of the transportation efficiency of the terminal device 20. For example, the work support device 10 of the work support system 1 starts the process of fig. 9A when the information acquisition unit 110 acquires the 1 st operation information D1 of the work device 30 from the outside (for example, the work device 30).

First, the information acquisition unit 110 determines in step S1002: the work device 30 to be processed currently performs the work on the field A1. For example, information acquisition unit 110 first compares the latest position of work implement 30 indicated by the latest positioning information among the 1 st operation information D1 with the geographical ranges of a plurality of fields a indicated by field information D2. Then, the field a including the latest position of working device 30 is determined as: work implement 30 is currently performing work on field A1. The field information D2 is acquired from an external device (for example, an external server) in advance and stored in the information storage unit 170. Alternatively, the field information D2 is generated based on the user input and stored in the information storage unit 170 in advance.

Next, in step S1004, the time determination unit 120 determines based on the 1 st operation information D1 and the field information D2 indicating the position and time of the working device 30: the estimated end time is estimated to be required until the end of the job in the field A1 determined in step S1002. The time determination unit 120 determines, based on the field information D2 and the 1 st operation information D1: the progress of the work machine 30 in the field A1 up to now. For example, the time determination unit 120 determines, as the positioning information at the start of the job, the time of the positioning information initially included in the field A1 among the positioning information of the work device 30 to be processed included in the 1 st operation information D1. The time determination unit 120 determines the time from the positioning information at the start of the job to the latest positioning information as: the current working time of working device 30 in field A1. The time determination unit 120 determines, based on the latest positioning information, based on the positioning information at the start time of the job: the area of the field A1 in which the work is completed is the work completion area. For example, the time determination unit 120 determines an area obtained by multiplying the length of the trajectory of the working device 30 from the positioning information at the start of the work to the latest positioning information by the working width of the working device 30 as: the work completion area up to the present time. The estimated end time is determined based on the area of the entire field A1 indicated by the field information D2, the area on which the work is completed, and the work time. For example, the time determination unit 120 may determine the estimated end time using the following equation 1.

(1) [ estimated end time ] = ([ area of the entire field A1 ] - [ work completion area ]) ]

In the present embodiment, the time determination unit 120 further determines, based on the estimated end time: it is estimated that the terminal device 20 ends the work in the field A1 (estimated end time). For example, the time determination unit 120 determines, as the estimated end time, a time obtained by adding the estimated end time to the latest positioning information of the operation performed by the terminal device 20 in the field A1.

Further, when there is a time to date when the work is not performed in the field A1 after the start of the work in the field A1, the work device 30 may exclude the positioning information from the above-described calculation processing.

Next, the time determination unit 120 determines in step S1006 that: whether the determined estimated end time satisfies the 1 st condition determined in advance. For example, when the estimated ending time is shorter than a predetermined threshold (for example, 1 hour), the time determining unit 120 determines that the 1 st condition is satisfied (YES in step S1006), and the process proceeds to step S1010. On the other hand, when the estimated ending time is equal to or longer than the predetermined threshold (for example, 1 hour), the time determining unit 120 determines that the condition is not satisfied (step S1006: NO), and ends the process. The value such as the threshold value of condition 1 is determined by setting at the time of factory shipment, but may be determined based on a user input.

Next, the information acquisition unit 110 acquires the 2 nd operation information D3 in step S1010. For example, the information acquisition unit 110 reads the 2 nd operation information D3 stored in advance in the information storage unit 170, and acquires the 2 nd operation information D3. In this case, the arithmetic device 14 of the work support device 10 acquires the operation information every time 1 or more transport devices 40 output the operation information before starting the process of fig. 9A, and stores the operation information in the information storage unit 170. Alternatively, the information acquisition unit 110 may acquire the 2 nd operation information D3 from an external server (for example, a server of a manufacturer of the conveying apparatus 40) that manages the conveying apparatus 40. Alternatively, when step S1010 is executed, the information acquisition unit 110 may acquire the operation information from 1 or more transport devices 40 (for example, transport devices 40 owned by a user of the work device 30) capable of transporting the work device 30 to be processed, and generate the 2 nd operation information D3.

Next, in step S1012, the object conveyance determination unit 130 determines, based on the 2 nd operation information D3: it is estimated that the conveyance device 40 needs to move from the current position toward the field A1. For example, the route search is performed for each of the 1 or more conveying apparatuses 40 of the 2 nd operation information D3 by using the position indicated by the positioning information of the 2 nd operation information D3, the field A1, and the map information. Then, based on the path search, it is calculated that: the time required for the carrying device 40 to move toward the field A1. The object conveyance determination unit 130 determines the calculated required time as the estimated movement time for moving from the current position of the conveyance device 40 toward the field A1. Alternatively, the object conveyance determination unit 130 may acquire the estimated movement time of the conveyance device 40 toward the field A1 based on the position indicated by the positioning information of the 2 nd operation information D3 and the field A1 by using the route search service provided by the external server.

Turning to fig. 9B, next, in step S1014, the object conveyance determination unit 130 selects, from among 1 or more conveyance devices 40, based on the estimated movement time determined in step S1012: the object carrying device 40A of the working device 30 should be carried. For example, the object conveyance determination unit 130 selects: the conveyance device 40 having the shortest estimated movement time determined in step S1012 among the 1 or more conveyance devices 40 is the target conveyance device 40A.

Next, in step S1016, the movement output unit 140 outputs movement instruction information indicating that the object carrying device 40A should move to the field A1 of the object to the terminal device 20. For example, the movement instruction information includes information indicating that: information indicating the object carrying device 40A (for example, carrying device ID), and information indicating the field A1 in the current job of the object (for example, field ID). In the present embodiment, the movement instruction information further includes: the estimated end time determined in step S1004. In the present embodiment, the movement output unit 140 outputs movement instruction information to the terminal device 20 of the object corresponding to the object conveying device 40A indicated by the 2 nd operation information D3. When the terminal device 20 is a vehicle-mounted terminal of the object carrying device 40A, the movement output unit 140 outputs movement instruction information to the object carrying device 40A. Alternatively, when the transport device 40 is managed by an external server, the movement output unit 140 may output movement instruction information to the external server.

In this way, the movement output unit 140 outputs movement instruction information indicating that the object carrying device 40A should move to the field A1 of the object to the terminal device 20, based on the determination by the time determination unit 120 that the estimated end time satisfies the condition 1 in step S1006.

Next, the display unit 210 of the terminal device 20 displays in step S1018: a screen based on the movement instruction information output in step S1016. For example, the display unit 210 displays the content shown in fig. 10. In the example of fig. 10, a conveyance device ID ("conveyance device to be conveyed") indicating the object conveyance device 40A to be moved to the field A1, a field ID ("field in the current operation") indicating the field A1 to be moved, and an instruction ("conveyance preparation for the working device toward the field A1 until bb is found in aa") indicating that the movement to the field A1 are associated and displayed.

In the example of fig. 10, in response to an instruction that the movement should be performed to the field A1, the estimated end time included in the movement instruction information is displayed as: the object carrying device 40A should reach the time of the deadline of the field A1. Thus, if the user sees the display of the terminal device 20, the user can grasp when it is appropriate to move the object carrying device 40A to the field A1.

Next, in step S1020 in fig. 9B, the conveyance destination acquisition unit 150 acquires the field A2 of the conveyance destination of the working device 30 based on the plan information D4. For example, the conveyance destination acquisition unit 150 first determines: it is estimated that the object conveying device 40A needs an estimated conveying time for conveying the terminal device 20 from the field A1 in operation to each field a of the plan information D4. The conveyance destination acquisition unit 150 performs route search based on the position of the field A1 indicated by the field information D2, the positions of the other fields a, and the map information. Then, based on the path search, it is determined that: the object conveying device 40A estimates a conveying time for conveying the work device 30 from the field A1 to each field a. The conveyance destination acquisition unit 150 may acquire the estimated conveyance time based on the position of the field A1 indicated by the field information D2 and the position of 1 or more fields a included in the plan information D4, using a route search service provided by an external server.

Then, the conveyance destination acquisition unit 150 determines: the estimated conveyance start time at which the conveyance device 40 starts the conveyance work device 30 is estimated. In the present embodiment, the conveyance destination acquisition unit 150 determines, as the estimated conveyance start time, the later of the estimated arrival time, which is the time obtained by adding the estimated movement time to the time when the movement instruction information is output by the movement output unit 140, and the estimated end time determined in step S1004, which is added to the time when the latest positioning information of the work is performed in the field A1 by the terminal device 20. In addition, the conveyance destination acquisition unit 150 determines, based on the estimated conveyance start time, the estimated conveyance time, and the information (the "work amount" in fig. 8) on the work amount in each field a indicated by the plan information D4: the estimated end time of the job end in each field a included in the plan information D4 is estimated. For example, when the "work amount" of the plan information D4 indicates a statistical work time in the field a, the conveyance destination acquisition unit 150 determines the statistical work time as: estimated work time required for work in field A2. When the "work amount" of the plan information D4 indicates the area of the field a and the work time per unit area, the conveyance destination acquisition unit 150 determines the result of dividing the area of the field a by the work time per unit area as the estimated work time.

Then, the conveyance destination acquisition unit 150 determines: an estimated conveyance start time and an estimated end time obtained by adding the estimated conveyance time and the estimated work time. The conveyance destination acquisition unit 150 determines, as the field A2, the field a having the longest estimated work time among the fields a having the estimated end time earlier than the predetermined time (work stop time). In the present embodiment, the job stop time is, for example: the predetermined time is the time when the work device 30 should stop the work or the period for completing the work. The job stop time may be a job receipt time (e.g., 18 hours and 00 minutes on the day, or 24 hours and 00 minutes on the day) of the operator of the working device 30, which is determined by a user input. Alternatively, the job stop time may be: the lifetime of work implement 30 determined by the setting, or the period for which the agricultural work should be completed for seasonal reasons. By such processing, the work support system 1 can instruct the work implement 30 to move toward the field a where the longest work can be performed, from among the fields a where the work can be completed up to the time of the work stop, and therefore, the efficiency of moving the work implement 30 can be improved.

Alternatively, the conveyance destination acquisition unit 150 may determine, as the conveyance destination field A2, a field a closest to the field A1 in the current operation among fields a whose estimated end times are earlier than the job stop time.

When there is no field a whose estimated end time is earlier than the job stop time, the conveyance destination acquisition unit 150 determines the field a whose estimated end time is earliest in terms of time as the conveyance destination field A2. Alternatively, the destination acquisition unit 150 may determine the storage place of the working device 30 (for example, a garage of the working device 30 determined by the setting) as the destination.

Next, in step S1022, the conveyance output unit 160 outputs: conveying instruction information indicating that the work implement 30 to be processed should be conveyed to the field A2. For example, the conveyance output unit 160 outputs conveyance instruction information including information specifying the field A2 to be conveyed determined in step S1020 to the terminal device 20 corresponding to the conveyance target device 40A.

Next, the display unit 210 of the terminal device 20 displays in step S1024: a screen based on the conveyance instruction information output in step S1022. For example, the display unit 210 displays the content shown in fig. 11. In the example of fig. 11, a conveyance device ID ("conveyance device for the object") indicating the conveyance device 40A that should convey the work device 30 to the field A2, a field ID ("field for the conveyance destination") indicating the field A2 for the conveyance destination, and an instruction ("please convey the work device for the object to the field A2") indicating that the work device 30 for the object should be conveyed to the field A2 are displayed in association with each other.

In this way, the work support system 1 determines from among 1 or more transport devices 40 capable of transporting the work device 30: the object carrying device 40A that actually carries out the carrying outputs movement instruction information based on the estimated end time estimated to be required until the working device 30 ends the work in the field A1 to the terminal device 20 corresponding to the object carrying device 40A. Thus, the work assistance system 1 can assist: the appropriate object carrying device 40A moves at an appropriate timing and carries the working device 30. Accordingly, the work support system 1 can improve the conveyance efficiency of the working device 30.

(embodiment 2)

In the work support system 1 according to embodiment 1, the movement output unit 140 outputs movement instruction information based on the determination in step S1006 that the estimated end time satisfies the predetermined condition 1. The work support system 1 according to the present embodiment differs from embodiment 1 in that movement instruction information is output based on the determination that the estimated end time satisfies the 2 nd condition different from the 1 st condition. The other points are the same as those in embodiment 1.

The work support system 1 of the present embodiment includes, like the work support system 1 described with reference to fig. 1 in embodiment 1: work support device 10, terminal device 20, and work device 30. The configuration of the work assistance devices 10 to 30 and the 1 st operation information D1 to the plan information D4 is the same as that of the 1 st embodiment described with reference to fig. 2 to 8, and therefore, the description thereof is omitted.

(action of work assistance System 1)

The work support system 1 according to the present embodiment is configured by the above-described functions, and performs the processing shown in fig. 12A and 12B as an example of the work support method, thereby improving the efficiency of carrying the support terminal device 20. For example, when the information acquisition unit 110 acquires the 1 st operation information D1 of the working device 30 from the outside (for example, the working device 30), the working assistance device 10 of the working assistance system 1 starts the process of fig. 12A.

First, in step S1102, the information acquisition unit 110 determines, as in step S1002 of fig. 9A: the work device 30 to be processed currently performs the work on the field A1.

Next, in step S1104, the time determination unit 120 determines the estimated end time, as in step S1004 of fig. 9A.

Next, in step S1106, the information acquisition unit 110 performs the same processing as in step S1010 of fig. 9A to acquire the 2 nd operation information D3.

In step S1108, the conveyance destination acquisition unit 150 performs the same processing as in step S1012 of fig. 9A, and determines based on the 2 nd operation information D3: the conveyance device 40 estimated to be 1 or more requires an estimated movement time for moving from the current position toward the field A1.

Next, the time determination unit 120 compares the estimated movement time determined in step S1108 with the estimated end time determined in step S1104 in step S1110 under the condition 2. For example, the time determination unit 120 determines: the shortest time among the estimated movement times determined in step S1108 is compared with the estimated end time determined in step S1104.

Next, the time determination unit 120 determines in step S1112: whether the result after the comparison in step S1110 satisfies the condition 2. For example, when the value obtained by adding the predetermined value to the shortest value among the estimated movement times of the object conveying device 40A is longer than the estimated end time determined in step S1104, the time determining unit 120 determines that the condition 2 is not satisfied (step S1112: NO). In this case, the work support system 1 ends the processing of fig. 12A and 12B.

On the other hand, when the value obtained by adding the predetermined value to the shortest value among the estimated movement times of the conveying device 40 is equal to or less than the estimated end time determined in step S1104, the time determining unit 120 determines that the condition 2 is satisfied (step S1112: YES). In this case, the job assistance system 1 advances the process to step S1114.

Here, the predetermined value added to the minimum value of the estimated movement time is, for example: a value determined by a setting at the time of factory shipment or a user input. This predetermined value corresponds to an allowable upper limit time for waiting for the completion of the work by the work device 30 after the object carrying device 40A reaches the field A1, for example. For example, the prescribed value may be: values from 0 to 30 minutes. The predetermined value may include: an error in the estimated movement time or a safety threshold value. Alternatively, when a predetermined waiting time is allowed after the working device 30 ends the work in the field A1 until the carrying device 40 reaches the field A1, a negative value (for example, 0 to-30 minutes) may be used as the predetermined value.

The processing of step S1116 to step S1124 is the same as that of step S1016 to step 1024 in fig. 9B, and therefore, the description thereof is omitted.

The work support system 1 according to the present embodiment outputs movement instruction information by the movement output unit 140 based on a result of comparing the estimated movement time of the conveyance device 40 to the field A1 with the estimated end time estimated to be the end of the work in the field A1. Thus, the work support system 1 can output movement instruction information at an appropriate timing corresponding to the current position of the carrying device 40. For example, the work assistance system 1 can reduce: when the carrying device 40 arrives at the field A1 earlier than the completion of the work by the working device 30, a waiting time may occur.

In addition, in embodiment 2 described above, in step S1112, the time determination unit 120 compares the shortest time (minimum value) among the estimated movement times determined in step S1108 with the estimated end time. Alternatively, the time determination unit 120 may compare the center value or average value of the plurality of estimated movement times with the estimated end time. Alternatively, the average value, the central value, and the minimum value of the estimated movement time may be compared with a predetermined threshold value. For example, the time determination unit 120 may determine that the comparison result satisfies the condition 2 when the minimum value of the estimated movement time is greater than 1.2 times the estimated end time.

(modification)

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

For example, in the above-described embodiment, the arithmetic device 34 of the working device 30 may implement a part or the whole of the functions executed by the working assistance device 10. When the arithmetic device 34 of the working device 30 can realize all the functions (the information acquisition unit 110 to the information storage unit 170) of the working assistance device 10, the working assistance system 1 may not include the working assistance device 10.

The 1 st operation information D1, the field information D2, the 2 nd operation information D3, and the plan information D4 stored in the information storage unit 170 may be data different from those of the above-described embodiment. For example, the 1 st operation information D1 may include operation information of a plurality of work devices 30. In this case, the work support device 10 executes the processing of fig. 9A and 9B for each of the plurality of work devices 30. At this time, when the object carrying determination unit 130 of the work support apparatus 10 determines the object carrying apparatus 40A in step S1014 of the process for the certain work apparatus 30, the mark during the movement is created in the 2 nd operation information D3, and the mark is excluded from the selection objects in step S1014 of the processes of the other work apparatuses 30. The object transfer determination unit 130 may remove the mark during the moving transfer when the information of the transfer completion is acquired from the terminal device 20. In this case, when the user, for example, the driver of the carrying device 40 finishes carrying the work device 30, information indicating the completion of carrying is input to the input/output device 22 of the terminal device 20. The display unit 210 of the terminal device 20 outputs information indicating the end of conveyance to the work support device 10.

The plan information D4 is not limited to the field a storing only the non-work, and may include: all fields a to be worked by the working device 30 to be processed including the field a after the work are completed. In this case, when the movement output unit 140 of the work support device 10 outputs the conveyance instruction information in step S1022 in fig. 9B, the completion flag is set for the field A1 to which the conveyance device 40 moves for conveying the work device 30. In addition, regarding the field a for which the work completion flag has been set, the conveyance destination acquisition unit 150 may exclude the field A2 from candidates for which the conveyance destination is determined in step S1020 in the processing of fig. 9A and 9B to be executed next.

In addition, in the case where the plurality of fields a to be worked by the working device 30 are arranged in the working order regardless of whether the work is completed or not, in the plan information D4, the conveyance destination acquisition unit 150 may determine, as the conveyance destination field A2, the field a stored next to the field A1 currently being worked in the plan information D4 in step S1020.

The processing performed by the job assistance system 1 may also be different from fig. 9A and 9B in order or processing content. For example, when the number of the transporting devices 40 of the work equipment 30 capable of transporting the processing target is only one, the work support system 1 may omit step S1014 and determine the transporting device 40 capable of transporting as the target transporting device 40A. Alternatively, the information for specifying the object conveying device 40A to convey the working device 30 may be acquired from the user input received by the external server or the input/output device 12 of the working support device 10 (or the input/output device 32 of the working device 30). In this case, the information acquisition unit 110 may acquire information indicating the object carrying device 40A as known information. Further, a modification of the processing performed in the steps of fig. 9A and 9B may be applied to the corresponding steps of fig. 12A and 12B.

In the above embodiment, the information acquisition unit 110 of the work support system 1 determines: in step S1002 in fig. 9A, working device 30 currently performs a work on field A1. However, the information acquiring unit 110 may acquire information for specifying the field A1 from the user input received by the working device 30, or by an external server or the input/output device 12.

In the process of step S1020 in fig. 9B, the conveyance destination acquisition unit 150 of the work support system 1 determines the field A2 to which the work implement 30 should be conveyed. However, the destination acquisition unit 150 may acquire information for specifying the field A2 on which the next job is to be performed, from the user input received by the external server or the input/output device 12.

In the process of step S1020 in fig. 9B, the conveyance destination acquisition unit 150 of the work support system 1 determines 1 field A2 to which the work implement 30 should be conveyed. However, the present invention is not limited thereto, and the destination acquiring unit 150 may determine a plurality of destination fields A2. For example, in the case where a plurality of fields a are provided at a time earlier than a predetermined time (job stop time) at step S1020, the conveyance destination acquisition unit 150 may determine all of the fields a as the conveyance destination fields A2. In this case, the conveyance output unit 160 outputs: and conveying instruction information including the fields A2 of the plurality of conveying destinations. The display unit 210 may display, on a screen of the field A2 indicating a plurality of transport destinations: "please carry to any one of these fields" or the like should carry the content to any one of the plurality of fields A2.

The time determination unit 120 determines the estimated end time of the job based on the 1 st operation information D1 and the field information D2, and the movement output unit 140 of the job support device 10 outputs movement instruction information based on the estimated end time. However, the information acquisition unit 110 of the work support device 10 may acquire advance notice information indicating that the work is terminated immediately from an external device (for example, the work device 30). In this case, the process of step S1006 in fig. 9A may be omitted, and the movement output unit 140 may output movement instruction information based on the advance notice information. For example, the output unit 320 of the working device 30 outputs advance notice information to the work support device 10 in response to the input/output device 32 receiving a user operation to advance notice that the work in the field A1 is completed. Then, in response to the information acquisition unit 110 receiving the advance notice information, the movement output unit 140 outputs movement instruction information to the terminal device 20.

Next, the conveyance destination acquisition unit 150 determines the estimated work time for each field a based on the planning information D4. Alternatively, the estimated work time may be determined by the conveyance destination acquisition unit 150, and the information acquisition unit 110 may acquire the estimated work time as known information. The conveyance destination acquisition unit 150 determines estimated end times at which the work ends in the plurality of fields a based on the estimated conveyance time and the estimated work time. Then, the conveyance destination acquisition unit 150 determines the conveyance destination field A2 from among the plurality of fields a based on the estimated end time. As an example, the conveyance destination acquisition unit 150 may determine, as the field A2, the field a having the longest estimated operation time among the fields a having the estimated end time earlier than the predetermined harvest time.

In step S1014 of fig. 9A, the object transfer determination unit 130 may determine the transfer device 40 having the shortest transfer time determined in step S1012 as the object transfer device 40A. The object transfer determining unit 130 is not limited thereto, and may determine the object transfer device 40A by another method. For example, the object carrying determination unit 130 may determine the carrying device 40 at a position closest to the field A1 in a straight line as the object carrying device 40A. Alternatively, the object transfer determining unit 130 may determine the object transfer device 40A based on a user input received by using the input/output device 12 or the like.

In step S1016 of fig. 9B, the movement output unit 140 outputs the movement based on the determination in step S1006 that the estimated end time satisfies the predetermined condition: including the estimated end time, the conveyance device ID of the object conveyance device 40A, and the field ID of the field A1. However, the movement output unit 140 may output based on the judgment that the estimated end time satisfies the predetermined condition: movement instruction information indicating that the object carrying device 40A corresponding to the "carrying device ID" of the movement instruction information alone should be moved to the field A1 without including the estimated end time. In this case, the display section 210 displays only: the object carrying device 40A should be moved to the field A1. Even in this case, the work support system 1 can instruct the movement of the conveying apparatus 40 at an appropriate timing.

In step S1020 in fig. 9B, the conveyance destination acquisition unit 150 determines the conveyance destination field A2 of the working device 30 based on the plan information D4, thereby acquiring conveyance destination information indicating the conveyance destination field A2. However, the destination acquiring unit 150 may acquire destination information of the field A2 indicating the destination from the outside. For example, the destination information may be acquired based on a user input by the input/output device 22 using the terminal device 20 or the input/output device 32 of the working device 30. Alternatively, the destination acquiring unit 150 may acquire the destination information of the field A2 indicating the destination from an external server operated by the manufacturer of the working device 30.

For example, in the above-described embodiment, after outputting and displaying the movement instruction information, the work support system 1 executes steps S1020 to S1024 to output and display the conveyance instruction information indicating: work implement 30 should be transported to field A2 at the transport destination. However, the process performed by the work support system 1 is not limited thereto. For example, the work support system 1 may execute steps S1022 to S1024 and display the movement instruction information and the conveyance instruction information at the same time, before displaying and outputting the movement instruction information in steps S1016 to S1018. Alternatively, the processing after step S1020 is omitted, and the movement instruction information is output at step S1018 at an appropriate timing, whereby the conveyance efficiency of work implement 30 can be improved.

The screen displayed by the display unit 210 is not limited to fig. 10 and 11. For example, the display unit 210 may display that the object carrying device 40A in fig. 10 should be moved to the field A1: a user interface (e.g., a clickable icon) indicating that the preparation for handling work implement 30 has been completed is received. After the user moves the object carrying device 40A to the field A1 and finishes the carrying preparation of the working device 30, the user input indicating that the carrying preparation is completed is performed using the user interface. In response to the user input, the input/output device 22 of the terminal device 20 outputs information indicating that the conveyance preparation is completed to the work support device 10. Further, the work support device 10 may start the processing in step S1020 or step S1022 in fig. 9B in response to the information indicating that the conveyance preparation is completed. According to such processing, the work support device 10 can output the conveyance instruction information at an appropriate timing when the conveyance preparation of the processing target work device 30 is completed.

In addition, the display unit 210 also displays in fig. 11: the time limit of the conveyance of the working device 30 to the field A2 of the conveyance destination. For example, the conveyance output unit 160 may determine, as the time obtained by subtracting the estimated working time of the field A2 determined in step S1020 in fig. 9B from the working time, a time obtained by: the time limit of the transportation of the work implement 30 to the field A2 of the transportation destination is set, and transportation instruction information including information indicating the time limit is output to the terminal device 20.

The movement output unit 140 and the conveyance output unit 160 may output the movement instruction information and the conveyance instruction information to the terminal device 20 at the same time. In this case, the output unit 220 may display: the case where the object carrying device 40A should be moved to the field A1 and the case where the terminal device 20 should be carried to the field A2 using the object carrying device 40A.

The above-described embodiments and modifications are examples, and the configurations described in the embodiments and modifications may be arbitrarily changed or/and arbitrarily combined within a range that does not interfere with the functions. Further, as long as the necessary functions can be realized, some of the functions described in the embodiments and modifications may be omitted.

(additionally remembered)

The job assistance method, the job assistance system, and the program described in the embodiments may be as follows.

The job assistance method according to the 1 st aspect includes the steps of: determining an estimated end time until the working device ends the work in the 1 st field based on the 1 st operation information indicating the position and time of the working device working in the 1 st field and the field information indicating the 1 st field in which the working device works; and outputting movement instruction information indicating that a carrying device carrying the working device should move toward the 1 st field based on the estimated end time.
