The notification program 330 may be provided as a computer program product recorded on the computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The notification program 330 may be recorded on the storage medium 1 and provided.

By reading and executing the notification program 330, the arithmetic device 220 cooperates with the input/output device 210 to operate the notification unit 250 that notifies the user of the work information acquired from the work management device 100, as shown in FIG. come true. The notification unit 250 acquires work information estimated by the work management device 100 and notifies the user of the work information. For example, the notification unit 250 displays the work area estimated by the work management device 100, the work period, and the work type. The notification unit 250 updates information registered in the work data 300 by user's operation.

(Operation of work management device)
When the engine is stopped, the work vehicle 30 transmits operation information to the arithmetic device 120 of the work management device 100 . When the operation information is received from the work vehicle 30, the arithmetic device 120 of the work management device 100 reads and executes the work management program 320. FIG. By executing the work management program 320, the computing device 120 executes the processing shown in FIG.

In step S110, the work estimating unit 160 implemented by the computing device 120 receives the operation information from the work vehicle 30, and estimates the work period and work area based on the received operation information. For example, the work estimation unit 160 estimates the work period from the time when the work vehicle 30 is started to the time when the work vehicle 30 is stopped. Further, the work estimation unit 160 estimates the work period based on the time when the work of the work vehicle 30 is started and the time when the work is finished, for example, the time when the work machine towed by the work vehicle 30 is driven and stopped. good too. The work period may be estimated based on the time when the work vehicle 30 enters the field and the time when it leaves the field. Also, the work period may be estimated based on the time when the engine of the work vehicle 30 starts and the time when the work vehicle 30 stops, for example, the engine stops. The work estimation unit 160 registers the estimated work period in the work data 300 .

The work estimation unit 160 estimates the work area based on the position information of the work vehicle 30 during the estimated work period. Specifically, the work vehicle 30 is equipped with a positioning device, for example, a GNSS (Global Navigation Satellite System) receiver, and acquires position information representing the position at each time it moves during the work period. The acquired position information is transmitted from the work vehicle 30 to the arithmetic device 120 of the work management device 100 . A work estimating unit 160 implemented by the computing device 120 estimates a work area based on the acquired position information. For example, the work area is represented by any closed figure, such as a polygon or rectangle, including the position represented by the acquired position information. For example, the work area is represented by a figure that encloses all of the acquired position information. The work estimation unit 160 registers the estimated work area in the work data 300 in association with the corresponding work period. The work area is thereby associated with the determined work duration.

In step S<b>120 , the work estimation unit 160 estimates the work type based on the operation information received from the work vehicle 30 . For example, the work estimation unit 160 estimates the work type using a learned model obtained by machine learning. In this case, the trained model is trained so as to estimate the work type from the operation information. Moreover, the work estimation unit 160 may estimate the work type based on the model of the work vehicle 30 or the work machine. In this case, the data holding unit 150 stores and holds in the storage device 140 work correspondence data that associates the model of the work vehicle 30 or work machine with the work type. The work estimation unit 160 estimates the work type based on the work correspondence data.

The work estimation unit 160 registers the estimated work type in the work data 300 in association with the corresponding work period. Thus, the work type is associated with the work period and work area estimated in step S110.

In step S130, the output unit 170 acquires output conditions for outputting the estimated work information. First, the output unit 170 acquires an output condition selected from one or more output conditions. The output condition is selected by inputting a condition selection operation for selecting the output condition to the input/output device 210 of the terminal 200 shown in FIG. When a condition selection operation is input to the input/output device 210, the notification unit 250 of the terminal 200 shown in FIG. The data holding unit 150 registers condition selection information representing the selected output condition in the setting data 310 based on the condition selection signal. The output unit 170 acquires condition selection information from the setting data 310 .

The output conditions include, for example, a first output condition, a second output condition, and a third output condition. The first output condition includes that work vehicle 30 has reached the set area. The setting area is set by inputting an area setting operation for setting the setting area to the input/output device 210 of the terminal 200 shown in FIG. The notification unit 250 of the terminal 200 shown in FIG. 3 outputs an area setting signal representing the setting area to the data holding unit 150 of the work management device 100 when an area setting operation is input to the input/output device 210 . The data holding unit 150 registers setting area information representing the setting area set in the setting data 310 based on the area setting signal.

The second output condition includes that the current time has reached the output time. The output time is set by inputting a time setting operation for setting the output time to the input/output device 210 of the terminal 200 shown in FIG. The notification unit 250 of the terminal 200 shown in FIG. 3 outputs a time setting signal representing the output time to the data holding unit 150 of the work management device 100 when a time setting operation is input to the input/output device 210 . The data holding unit 150 registers set time information representing the output time set in the setting data 310 based on the time setting signal.

The third output condition includes that the set time has passed since the time when the work vehicle 30 stopped. The set time is set by inputting a time setting operation for setting the set time to the input/output device 210 of the terminal 200 shown in FIG. The notification unit 250 of the terminal 200 shown in FIG. 3 outputs a time setting signal representing the set time to the data holding unit 150 of the work management device 100 when a time setting operation is input to the input/output device 210 . The data holding unit 150 registers set time information representing the set time set in the setting data 310 based on the time setting signal.

At step S140 shown in FIG. 4, the output unit 170 determines whether the output condition represented by the acquired condition selection information is satisfied. When determining that the output condition is satisfied, the output unit 170 executes the process of step S150. When determining that the output condition is not satisfied, the output unit 170 waits until the output condition is satisfied.

For example, when the first output condition is selected, the output unit 170 determines whether the first output condition is satisfied. Specifically, after finishing the work in the field, the worker moves the work vehicle 30 shown in FIG. The work vehicle 30 outputs operation information to the arithmetic device 120 of the work management device 100 when the engine is stopped. The output unit 170 implemented by the computing device 120 shown in FIG. 3 extracts the position information of the work vehicle 30 from the operation information. The output unit 170 acquires the latest position information among the extracted position information as the stop position where the engine of the work vehicle 30 is stopped. The output unit 170 also acquires setting area information from the setting data 310 . The output unit 170 determines whether the stop position is included in the set area represented by the set area information. When the stop position is included in the set area, the output unit 170 determines that the output condition is satisfied, and executes the process of step S150. When the stop position is not included in the set area, the output unit 170 determines that the output condition is not satisfied, and waits for the operation information to be output from the work vehicle 30 .

When the second output condition is selected, the output unit 170 determines whether the second output condition is satisfied. Specifically, the output unit 170 acquires the set time information from the setting data 310 and compares the output time represented by the acquired set time information with the current time. When the current time reaches the output time, the output unit 170 determines that the output condition is satisfied, and executes the process of step S150. When the current time has not reached the output time, the output unit 170 determines that the output condition is not satisfied, and waits until the output time is reached.

When the third output condition is selected, the output unit 170 determines whether the third output condition is satisfied. Specifically, output unit 170 acquires set time information from setting data 310 . The work vehicle 30 shown in FIG. 1 outputs operation information to the arithmetic device 120 of the work management device 100 when the engine is stopped. The output unit 170 implemented by the computing device 120 shown in FIG. 3 determines that the engine has been stopped when the operation information is received. The output unit 170 determines whether or not the set time indicated in the set time information has passed since the operation information was received. When the elapsed time has passed since the operation information was received, the output unit 170 determines that the output condition is satisfied, and executes the process of step S150. When the elapsed time has not elapsed since the operation information was received, the output unit 170 determines that the output condition is not satisfied, and waits until the elapsed time has elapsed since the operation information was received.

In step S150 shown in FIG. 4, the output unit 170 executes processing for informing the user of the work information estimated by the work estimation unit 160. FIG. Specifically, output unit 170 shown in FIG. 3 outputs a notification signal representing the estimated work information to notification unit 250 of terminal 200 . For example, the output unit 170 sends an e-mail containing work information. The notification unit 250 of the terminal 200 receives the e-mail and displays the work information on the input/output device 210 of the terminal 200 shown in FIG.

The user confirms the displayed work information and inputs an operation for confirming the work information to the input/output device 210 of the terminal 200 shown in FIG. For example, the user confirms the work information described in the e-mail and inputs an operation to display the work data 300 stored in the storage device 140 of the work management device 100 on the input/output device 210 of the terminal 200. . The notification unit 250 of the terminal 200 shown in FIG. 3 transmits a request signal requesting the work data 300 to the data holding unit 150 of the work management apparatus 100 according to the user's operation. The data holding unit 150 transmits work information included in the work data 300 to the notification unit 250 in response to the request signal. Upon receiving the work information, the notification unit 250 displays the received work information, such as the work area and the work type, on the input/output device 210 .

When the displayed work information is incorrect, the user inputs a correction operation to the input/output device 210 to correct the work information. The notification unit 250 transmits correction information for correcting work information, for example, information representing the type of work after correction, to the data holding unit 150 of the work management apparatus 100 based on the correction operation. The data holding unit 150 updates the work data 300 based on the received correction information.

When the displayed work information is correct, the user inputs a confirmation operation to the input/output device 210 to confirm the work information. The notification unit 250 transmits information indicating that the work information is correct to the data holding unit 150 of the work management device 100 based on the confirmation operation. The data holding unit 150 determines the work information of the work data 300 based on the received information.

In this way, the work information estimated by the work management system 1000 is notified to the user. As a result, it is possible to reduce forgetting to confirm by the user.

(Modification)
The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not hinder the functions. The number of output conditions set in the setting data 310 is not limited to three, and any number of one or more may be selected. Moreover, the set output conditions are not limited to the above-described embodiment, and may be set arbitrarily.

Although the output unit 170 selects one output condition from one or more output conditions in step S130 shown in FIG. 4, it may select two or more output conditions. For example, the output unit 170 outputs work information when any one of the selected two or more output conditions is satisfied. Further, the output unit 170 may output the work information when all the output conditions among the selected two or more output conditions are satisfied.

The output unit 170 may set the output condition based on the time when the user checked the work information in the past. When the user confirms the work information, the notification unit 250 of the terminal 200 shown in FIG. The data holding unit 150 stores the time when the requested request signal is received as the time when the user confirms the work usage.

The output unit 170 may set, as an output condition, that the current time is the access time zone in which work information was checked most frequently in a day at the time when work information was checked in the past. For example, the output unit 170 calculates the access time period during which the work information was checked most frequently in one day, based on the time when the work information was checked in the past. The output unit 170 sets the arrival of the calculated access time period as an output condition. Thereby, the output unit 170 outputs the work information when the frequency of confirming the work information in one day is the highest.

In addition, based on the times at which work information was checked in the past, the output unit 170 calculates the average time of the time at which work information was checked in a day, and the access time with the highest frequency of checking work information in a day. It may be calculated as a band. For example, the output unit 170 may set the output condition to reach a time earlier than the calculated average time by a predetermined time. In this case, the output unit 170 outputs the work information at a predetermined time earlier than when the user confirms the work information.

In step S110, the output unit 170 may perform processing for notifying the user of the scheduled time at which the estimation processing will be completed. For example, the output unit 170 calculates the estimated time to complete the estimation process according to the received operation information and the load status of the arithmetic unit 120 of the work management apparatus 100 shown in FIG. The output unit 170 outputs schedule information representing the calculated scheduled time to the notification unit 250 of the terminal 200 shown in FIG. For example, the output unit 170 transmits an e-mail containing schedule information. The notification unit 250 of the terminal 200 receives the e-mail and displays the estimated time of completion of the estimation process on the input/output device 210 of the terminal 200 shown in FIG. By the user confirming the scheduled time, the work management system 1000 can reduce unnecessary access to the work management apparatus 100 by the user before the estimation process is completed.

The output unit 170 may calculate the scheduled time for completing the estimation process based on the process schedule included in the setting data 310 . The processing schedule represents the order of operation information in which the work estimation unit 160 performs estimation processing when the work estimation unit 160 receives operation information from a plurality of work vehicles 30 . Moreover, the processing schedule may represent the scheduled time at which the work estimation unit 160 starts the estimation processing of each piece of operation information. The output unit 170 acquires the processing schedule from the setting data 310, and calculates the scheduled time to start the estimation processing for the received operation information based on the processing schedule. Based on the calculated scheduled time, the output unit 170 calculates the scheduled time at which the estimation process will be completed.

The work estimating unit 160 may determine the time at which the work estimating unit 160 starts the estimation process based on the time when the user checked the work information in the past. For example, the work estimating unit 160 calculates the time to start the estimation process so that the estimation process is completed before reaching the access time slot in which the work information is checked most frequently in a day. Specifically, the work estimating unit 160 calculates the access time zone in which the work information was checked most frequently in a day at the time when the work information was checked in the past. Also, the work estimation unit 160 calculates the processing time required for the estimation process based on the operation information. The work estimator 160 calculates a time that is earlier than the calculated processing time than the start of the calculated access time period as the start time of the estimation process. The calculated time is registered in the processing schedule of the setting data 310 as the time to start the estimation process. The work estimation unit 160 starts the estimation process by executing step S110 shown in FIG. 4 at the time registered in the process schedule.

Also, the output unit 170 may output the schedule information to the terminal 200 at a set time. For example, the output unit 170 outputs the schedule information to the terminal 200 when an output condition selected from one or more output conditions is satisfied. The process of determining whether the output condition is satisfied may be the same process as steps S130 and S140 shown in FIG.

In step S150 shown in FIG. 4, the output unit 170 may output information indicating that the estimation process has been completed instead of the work information. In this case, the notification unit 250 of the terminal 200 displays on the input/output device 210 that the estimation process has been completed. The user confirms the information displayed on the input/output device 210 and inputs an operation for displaying the work information. The notification unit 250 acquires work information from the data holding unit 150 of the work management apparatus 100 and displays the acquired work information according to the user's operation.

In this case, the notification signal includes information representing the selected output condition, and output unit 170 is realized by work management device 100 and terminal 200 . For example, when the first output condition is selected, the output unit 170 realized by the terminal 200 acquires the position of the terminal 200, and when the position of the terminal 200 is included in the setting area, outputs the work information. Output to notification unit 250 . The notification unit 250 displays the output workplace method on the input/output device 210 . In this case, terminal 200 includes a positioning device for measuring its own position. When the second output condition is selected, the output unit 170 of the terminal 200 outputs work information to the notification unit 250 when the set output time is reached. The notification unit 250 displays the output work information on the input/output device 210 . When the third output condition is selected, the output unit 170 of the work management device 100, upon confirming that the work vehicle has stopped, calculates the notification time when the set time has elapsed since the time when the work vehicle 30 stopped. The output unit 170 of the work management device 100 transmits a notification signal including information representing the calculated notification time to the output unit 170 of the terminal 200 . The output unit 170 outputs work information based on the notification signal when the notification time is reached. The notification unit 250 displays the output work information on the input/output device 210 .

Although the operation information of the work vehicle 30 has been shown to be sent to the work management device 100 when the engine is stopped, it is not limited to this, and may be sent to the work management device 100 at any timing. The work vehicle 30 may transmit operation information to the arithmetic device 120 of the work management device 100 at predetermined intervals while it is in operation.

In this case, the output unit 170 determines in step S140 shown in FIG. 4 that the output condition is satisfied when the work vehicle 30 enters the setting area set in the setting data 310, for example, the storage location 400 area. good. For example, the output unit 170 acquires position information of the work vehicle 30 from operation information received at predetermined intervals. When the position information received most recently is not included in the set area and the position information received immediately before is not included in the setting information, output unit 170 determines that work vehicle 30 has entered the set area. When the output unit 170 determines that the work vehicle 30 has entered the set area, the output unit 170 executes the process of step S150 shown in FIG.

Further, the output unit 170 may determine that the output condition is satisfied when the set time set in the setting data 310 has elapsed after the work vehicle 30 stopped. For example, the output unit 170 acquires position information of the work vehicle 30 from operation information received at predetermined intervals. When the position indicated by the position information received most recently is the same as the position indicated by the position information received immediately before that, output unit 170 determines that work vehicle 30 has stopped. The output unit 170 executes the process of step S150 shown in FIG. 4 when the set time has elapsed after determining that the work vehicle 30 has stopped. The output unit 170 determines that the work vehicle 30 has stopped when the work vehicle 30 has not moved for a predetermined time or more, for example, when the position represented by the position information of the work vehicle 30 remains the same for a predetermined time. may Further, the output unit 170 may determine that the work vehicle 30 has stopped when, for example, the distance traveled by the position indicated by the position information of the work vehicle 30 in a predetermined time is equal to or less than a threshold.

The embodiments and modifications described above are examples, and the configurations described in the embodiments and modifications may be arbitrarily changed and/or combined as long as the functions are not hindered. may Furthermore, some of the functions described in the embodiment and modifications may be omitted as long as the required functions can be realized. For example, the work management system 1000 may omit the terminal 200 and use the terminal 200 as a device outside the system.
