[0016] (Embodiment) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the work management system 1000 includes a work management device 100 and a terminal 200. The work management device 100 is communicatively connected to the terminal 200 and a work vehicle 30 via a network 20, for example, the Internet.

[0017] The work management device 100 acquires operation information on the field from the work vehicle 30, and performs an estimation process to estimate work information related to the work, such as the work period, work type, work area, etc., based on the acquired operation information. The work type indicates the type of work performed in the field, such as plowing, leveling, fertilizing, planting, etc. The work area indicates the area where the work was performed, such as the area within the field where the work was performed, or the area of ​​the entire field where the work was performed.

[0018] Furthermore, the work management apparatus 100 outputs the estimated work information to the terminal 200 at a set time. The terminal 200 notifies a user, such as a worker or a field owner, of the work information based on the work information. The user can check the work information by receiving the notification from the work management system 1000.

[0019] In this way, the work management system 1000 notifies the user of the estimated work information, thereby reducing the occurrence of the user forgetting to check. Furthermore, the work management system 1000 notifies the user after the estimation process is completed, thereby reducing unnecessary access to the work management device 100 by the user before the estimation process is completed, thereby improving the user's work efficiency.

[0020] The operation information acquired from the work vehicle 30 includes information indicating the state of the work vehicle 30 when working in the field, such as the speed, steering angle, engine RPM, ON / OFF status of various clutches, position information of the work vehicle 30 at each time, and time information indicating the time when various information was output. When the work vehicle 30 is a vehicle that tows a work machine, such as a tractor, the operation information may include information such as the PTO (power take-off) RPM when transmitting power to the work machine, and the hitch height and lift arm angle that indicate the attitude of the work machine.

[0021] The configuration of the work management apparatus 100 will be described. The work management apparatus 100 includes an input / output device 110, a calculation device 120, a communication device 130, and a storage device 140. The work management apparatus 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input / output device 110. The input / output device 110 also outputs the results of the processing executed by the calculation device 120. The input / output device 110 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input / output device 110 may be omitted.

[0022] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers operation information acquired from the work vehicle 30 to the arithmetic device 120. The communication device 130 also transfers signals generated by the arithmetic device 120 to the terminal 200. The communication device 130 includes various interfaces, such as a network interface card (NIC) and a universal serial bus (USB).

[0023] The storage device 140 stores various data for estimating the task type, such as task data 300, setting data 310, and task management program 320. The storage device 140 is used as a non-transitory tangible storage medium for storing the task management program 320. The task management program 320 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

[0024] The work data 300 includes data related to work in the field, for example data calculated from operation information from the work vehicle 30. For example, the work data 300 includes work period information indicating the work period, work area information indicating the work area, and work type information indicating the work type. The work period information, work area information, and work type information are registered in association with the work data 300. The work period indicates the time when work in the field started and ended. The work area indicates the area where work in the field was performed, for example the position and shape. The work type indicates the type of work performed in the field, for example plowing, leveling, fertilizing, planting, etc.

[0025] The setting data 310 includes data on the time when the work management apparatus 100 outputs the work information to the terminal 200. For example, the work management apparatus 100 outputs the work information when the work vehicle 30 reaches a set area, for example, a storage location of the work vehicle 30. For example, consider a case where the work vehicle 30 moves from a farm field 440 to a storage location 400 along a route 420 as shown in FIG. 2. In this case, the work management apparatus 100 outputs the work information when the work vehicle 30 reaches the storage location 400, for example, when the work vehicle 30 enters an area included in the storage location 400. The setting data 310 includes set area information representing a set area, for example, an area of ​​the storage location 400. The work management apparatus 100 may also output the work information at an output time, for example, at a fixed time every day. In this case, the setting data 310 includes output time information representing the output time. The work management apparatus 100 may also output the work information when a set time has elapsed since the work vehicle 30 stopped. In this case, the setting data 310 includes setting time information that indicates the setting time.

[0026] The task data 300 and the setting data 310 are read by the arithmetic device 120 shown in Fig. 1 and used for various data processing for outputting task information at a set time. The arithmetic device 120 reads and executes the task management program 320 from the storage device 140, estimates a task type, and outputs information indicating the estimated task type at a set time. For example, the arithmetic device 120 includes a central processing unit (CPU) and the like.

[0027] By reading and executing the work management program 320, the calculation device 120 realizes a data storage unit 150, a work estimation unit 160, and an output unit 170, as shown in Fig. 3. The data storage unit 150 stores work data 300 and setting data 310. The work estimation unit 160 estimates a work type based on operation information obtained from the work vehicle 30, and registers it in the work data 300. The output unit 170 outputs the estimated work type at a set time.

[0028] Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input / output device 210, a calculation device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the calculation device 220 to execute processing is input to the input / output device 210. In addition, the input / output device 210 outputs the result of the calculation device 220 executing the processing. The input / output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

[0029] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers work information acquired from the work management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the work management device 100. The communication device 230 includes various interfaces, such as a wireless LAN (Local Area Network) transceiver, a NIC (Network Interface Card), and a USB (Universal Serial Bus).

[0030] The storage device 240 stores various data for notifying a user of work information acquired from the work management device 100, for example, a notification program 330. The storage device 240 is used as a non-transitory tangible storage medium for storing the notification program 330. The notification program 330 may be provided as a computer program product recorded in a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The notification program 330 may be provided by being recorded in the storage medium 1.

[0031] The arithmetic device 220 reads and executes the notification program 330, thereby realizing a notification unit 250 that cooperates with the input / output device 210 to notify the user of work information acquired from the work management device 100, as shown in Fig. 3. The notification unit 250 acquires the 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, work period, and work type estimated by the work management device 100. The notification unit 250 updates the information registered in the work data 300 in response to a user operation.

[0032] (Operation of the work management device) When the work vehicle 30 stops the engine, it transmits operation information to the arithmetic device 120 of the work management device 100. When the arithmetic device 120 of the work management device 100 receives the operation information from the work vehicle 30, it reads and executes the work management program 320. By executing the work management program 320, the arithmetic device 120 executes the processing shown in FIG.

[0033] In step S110, the work estimation unit 160 realized by the calculation device 120 receives operation information from the work vehicle 30 and estimates the work period and the 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. The work estimation unit 160 may also estimate the work period based on the time when the work of the work vehicle 30 starts and ends, for example, the time when the work machine towed by the work vehicle 30 starts and stops. The work period may also be estimated based on the time when the work vehicle 30 enters the field and the time when it leaves the field. The work period may also 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 time when the engine stops. The work estimation unit 160 registers the estimated work period in the work data 300.

[0034] 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 indicating the position at each time when the work vehicle 30 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. The work estimation unit 160 realized by the arithmetic device 120 estimates the work area based on the acquired position information. For example, the work area is represented by any closed figure, such as a polygon or a rectangle, including the position represented in the acquired position information. For example, the work area is represented by a figure that surrounds all of the acquired position information. The work estimation unit 160 associates the estimated work area with the corresponding work period and registers it in the work data 300. As a result, the work area is associated with the determined work period.

[0035] In step S120, 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 trained model obtained by machine learning. In this case, the trained model is trained to estimate the work type from the operation information. The work estimation unit 160 may also estimate the work type based on the model of the work vehicle 30 or work machine. In this case, the data retention unit 150 stores and retains work correspondence data that associates the model of the work vehicle 30 or work machine with the work type in the storage device 140. The work estimation unit 160 estimates the work type based on the work correspondence data.

[0036] The task estimation unit 160 associates the estimated task type with the corresponding task period and registers it in the task data 300. In this way, the task type is associated with the task period and task area estimated in step S110.

[0037] In step S130, the output unit 170 acquires an output condition for outputting the estimated work information. First, the output unit 170 acquires a selected output condition from among one or more output conditions. The output condition is selected by inputting a condition selection operation for selecting an output condition to the input / output device 210 of the terminal 200 shown in FIG. 1. When a condition selection operation is input to the input / output device 210, the notification unit 250 of the terminal 200 shown in FIG. 3 outputs a condition selection signal representing the selected output condition to the data storage unit 150 of the work management device 100. The data storage 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 the condition selection information from the setting data 310.

[0038] 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 the work vehicle 30 has reached the set area. The set area is set by inputting an area setting operation for setting the set area to the input / output device 210 of the terminal 200 shown in FIG. 1. When the area setting operation is input to the input / output device 210, the notification unit 250 of the terminal 200 shown in FIG. 3 outputs an area setting signal representing the set area to the data holding unit 150 of the work management device 100. The data holding unit 150 registers set area information representing the set area set in the setting data 310 based on the area setting signal.

[0039] 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 into the input / output device 210 of the terminal 200 shown in Fig. 1. When the time setting operation is input into the input / output device 210, the notification unit 250 of the terminal 200 shown in Fig. 3 outputs a time setting signal indicating the output time to the data holding unit 150 of the work management apparatus 100. The data holding unit 150 registers setting time information indicating the output time set in the setting data 310 based on the time setting signal.

[0040] The third output condition includes that a set time has elapsed since the time the work vehicle 30 stopped. The set time is set by inputting a time setting operation for setting the set time into the input / output device 210 of the terminal 200 shown in Fig. 1. When a time setting operation is input into the input / output device 210, the notification unit 250 of the terminal 200 shown in Fig. 3 outputs a time setting signal representing the set time to the data retention unit 150 of the work management apparatus 100. The data retention unit 150 registers set time information representing the set time set in the setting data 310 based on the time setting signal.

[0041] 4, the output unit 170 determines whether the output condition indicated in the acquired condition selection information is satisfied. If the output unit 170 determines that the output condition is satisfied, it executes the process of step S150. If the output unit 170 determines that the output condition is not satisfied, it waits until the output condition is satisfied.

[0042] For example, when the first output condition is selected, the output unit 170 judges whether the first output condition is satisfied. Specifically, when the worker finishes work in the field, the worker moves the work vehicle 30 shown in FIG. 1 to the storage location 400 and stops the engine of the work vehicle 30. When the engine is stopped, the work vehicle 30 outputs operation information to the arithmetic device 120 of the work management device 100. The output unit 170 realized by the arithmetic device 120 shown in FIG. 3 extracts position information of the work vehicle 30 from the operation information. The output unit 170 acquires the most recent position information of the extracted position information as the stop position where the engine of the work vehicle 30 is stopped. In addition, the output unit 170 acquires the set area information from the setting data 310. The output unit 170 judges whether the stop position is included in the set area represented in the set area information. When the stop position is included in the set area, the output unit 170 judges 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 section 170 determines that the output condition is not satisfied, and waits for the work vehicle 30 to output operation information.

[0043] 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 setting time information from the setting data 310, and compares the output time represented in the acquired setting time information with the current time. When the current time has reached 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.

[0044] When the third output condition is selected, the output unit 170 determines whether the third output condition is satisfied. Specifically, the output unit 170 acquires the set time information from the setting data 310. When the engine of the work vehicle 30 shown in FIG. 1 is stopped, the work vehicle 30 outputs the operation information to the arithmetic device 120 of the work management device 100. The output unit 170 realized by the arithmetic device 120 shown in FIG. 3 determines that the engine is stopped when the operation information is received. The output unit 170 determines whether the set time represented by the set time information has elapsed since the operation information was received. When the elapsed time has elapsed since the operation information was received, the output unit 170 executes the process of step S150, assuming that the output condition is satisfied. 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.

[0045] In step S150 shown in Fig. 4, the output unit 170 executes a process for notifying the user of the task information estimated by the task estimation unit 160. Specifically, the output unit 170 shown in Fig. 3 outputs a notification signal representing the estimated task information to the notification unit 250 of the terminal 200. For example, the output unit 170 sends an email including the task information. The notification unit 250 of the terminal 200 receives the email and displays the task information on the input / output device 210 of the terminal 200 shown in Fig. 1.

[0046] The user checks the displayed work information and inputs an operation to confirm the work information to the input / output device 210 of the terminal 200 shown in Fig. 1. For example, the user checks the work information described in an email and inputs an operation to display the work data 300 stored in the storage device 140 of the work management apparatus 100 to the input / output device 210 of the terminal 200. In response to the user's operation, the notification unit 250 of the terminal 200 shown in Fig. 3 transmits a request signal to the data storage unit 150 of the work management apparatus 100 to request the work data 300. In response to the request signal, the data storage unit 150 transmits the work information included in the work data 300 to the notification unit 250. Upon receiving the work information, the notification unit 250 displays the received work information, for example, the work area and the work type, on the input / output device 210.

[0047] When the displayed work information is incorrect, the user inputs a correction operation to correct the work information into the input / output device 210. Based on the correction operation, the notification unit 250 transmits correction information for correcting the work information, for example information indicating the corrected work type, to the data retention unit 150 of the work management apparatus 100. The data retention unit 150 updates the work data 300 based on the received correction information.

[0048] When the user believes that the displayed work information is correct, the user inputs a confirmation operation to confirm the work information into the input / output device 210. Based on the confirmation operation, the notification unit 250 transmits information indicating that the work information is correct to the data retention unit 150 of the work management apparatus 100. The data retention unit 150 confirms the work information in the work data 300 based on the received information.

[0049] In this way, the work management system 1000 notifies the user of the estimated work information, thereby reducing the occurrence of the user forgetting to check.

[0050] (Modification) The configuration described in the embodiment is an example, and the configuration can be changed as long as the function is not impaired. The number of output conditions set in the setting data 310 is not limited to three, and may be arbitrarily selected as long as it is one or more. In addition, the set output conditions are not limited to the above-mentioned embodiment, and may be arbitrarily set.

[0051] Although an example in which the output unit 170 selects one output condition from one or more output conditions in step S130 shown in Fig. 4 has been shown, two or more output conditions may be selected. For example, when any one of the two or more selected output conditions is satisfied, the output unit 170 outputs the work information. Furthermore, when all of the two or more selected output conditions are satisfied, the output unit 170 may output the work information.

[0052] The output unit 170 may set the output conditions based on the time when the user previously confirmed the work information. When the user confirms the work information, the notification unit 250 of the terminal 200 shown in Fig. 3 outputs a request signal to the data storage unit 150 of the work management apparatus 100 to request the work data 300. The data storage unit 150 stores the time when the request signal was received as the time when the user confirmed the work usage.

[0053] The output unit 170 may set as an output condition that the current time is an access time period during which the work information was most frequently checked in a day at the time when the work information was checked in the past. For example, the output unit 170 calculates an access time period during which the work information was most frequently checked in a day based on the time when the work information was checked in the past. The output unit 170 sets as an output condition that the calculated access time period is reached. In this way, the output unit 170 outputs the work information when the work information was most frequently checked in a day.

[0054] Furthermore, the output unit 170 may calculate the average time of the time that the work information was confirmed in a day based on the time that the work information was confirmed in the past as the access time period during which the work information was confirmed most frequently in a day. For example, the output unit 170 may set an output condition that a time that is a predetermined time earlier than the calculated average time is reached. In this case, the output unit 170 outputs the work information at a time that is a predetermined time earlier than the time that the user confirms the work information.

[0055] In step S110, the output unit 170 may execute a process for notifying the user of the scheduled time at which the estimation process is to be completed. For example, the output unit 170 calculates the scheduled time at which the estimation process is to be completed according to the received operation information and the load status of the arithmetic device 120 of the work management apparatus 100 shown in FIG. 1. The output unit 170 outputs schedule information indicating the calculated scheduled time to the notification unit 250 of the terminal 200 shown in FIG. 3. For example, the output unit 170 transmits an e-mail including the schedule information. The notification unit 250 of the terminal 200 receives the e-mail and displays the scheduled time at which the estimation process is to be completed on the input / output device 210 of the terminal 200 shown in FIG. 1. By the user checking 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.

[0056] The output unit 170 may calculate the scheduled time at which the estimation process will be completed based on the processing schedule included in the setting data 310. The processing schedule indicates the order in which the work estimation unit 160 performs estimation processing on the operation information when the work estimation unit 160 receives operation information from a plurality of work vehicles 30. The processing schedule may also indicate the scheduled time at which the work estimation unit 160 starts estimation processing for each piece of operation information. The output unit 170 acquires the processing schedule from the setting data 310, and calculates the scheduled time at which the estimation process will start for the received operation information based on the processing schedule. The output unit 170 calculates the scheduled time at which the estimation process will be completed based on the calculated scheduled time.

[0057] The work estimation unit 160 may determine the time when the work estimation unit 160 starts the estimation process based on the time when the user previously confirmed the work information. For example, the work estimation unit 160 calculates the time when the estimation process starts so that the estimation process is completed before the access time period when the work information is most frequently confirmed in one day is reached. Specifically, the work estimation unit 160 calculates the access time period when the work information is most frequently confirmed in one day at the time when the work information was previously confirmed. In addition, the work estimation unit 160 calculates the processing time required for the estimation process based on the operation information. The work estimation unit 160 calculates a time earlier than the start of the calculated access time period by at least the calculated processing time as the time when the estimation process starts. The calculated time is registered in the processing schedule of the setting data 310 as the time when the estimation process starts. The work estimation unit 160 executes step S110 shown in FIG. 4 at the time registered in the processing schedule to start the estimation process.

[0058] Furthermore, the output unit 170 may output the schedule information to the terminal 200 at a set time. For example, when a selected output condition is satisfied from among one or more output conditions, the output unit 170 outputs the schedule information to the terminal 200. The process of determining whether the output condition is satisfied may be the same as the process of steps S130 and S140 shown in FIG.

[0059] 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 checks the information displayed on the input / output device 210 and inputs an operation to display the work information. The notification unit 250 acquires the work information from the data storage unit 150 of the work management apparatus 100 in response to the user's operation, and displays the acquired work information.

[0060] The output unit 170 of the work management device 100 may execute the process of step S150 shown in FIG. 4 before the output condition is satisfied, and transmit a notification signal representing the work information to the notification unit 250 of the terminal 200. In this case, the notification signal includes information representing the selected output condition, and the output unit 170 is realized by the work management device 100 and the 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 outputs the work information to the notification unit 250 when the position of the terminal 200 is included in the set area. The notification unit 250 displays the output work information on the input / output device 210. In this case, the terminal 200 is equipped with a positioning device for measuring the position of the terminal 200. When the second output condition is selected, the output unit 170 of the terminal 200 outputs the 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, upon confirming that the work vehicle has stopped, the output unit 170 of the work management device 100 calculates the notification time when a set time has elapsed since the time the work vehicle 30 stopped. The output unit 170 of the work management device 100 transmits a notification signal including information indicating the calculated notification time to the output unit 170 of the terminal 200. Based on the notification signal, the output unit 170 outputs work information when the notification time is reached. The notification unit 250 displays the output work information on the input / output device 210.

[0061] Although an example has been shown in which the operation information of the work vehicle 30 is transmitted to the work management device 100 when the engine is stopped, this is not limited thereto, and the operation information may be transmitted to the work management device 100 at any timing. When the work vehicle 30 is operating, it may transmit the operation information to the calculation device 120 of the work management device 100 at predetermined intervals.

[0062] In this case, the output unit 170 may determine in step S140 shown in Fig. 4 that the output condition is satisfied when the work vehicle 30 enters a set area set in the setting data 310, for example, the area of ​​the storage location 400. For example, the output unit 170 acquires position information of the work vehicle 30 from operation information received at a predetermined interval. When the most recently received position information is not included in the set area and the position information received immediately before that is not included in the set information, the output unit 170 determines that the work vehicle 30 has entered the set area. When the output unit 170 determines that the work vehicle 30 has entered the set area, it executes the process of step S150 shown in Fig. 4.

[0063] The output unit 170 may also determine that the output condition is satisfied when a set time set in the setting data 310 has elapsed since the work vehicle 30 stopped. For example, the output unit 170 acquires the position information of the work vehicle 30 from the operation information received at a predetermined interval. When the position represented by the most recently received position information is the same as the position represented by the position information received immediately before, the output unit 170 determines that the work vehicle 30 has stopped. When the set time has elapsed since the output unit 170 determined that the work vehicle 30 has stopped, the output unit 170 executes the process of step S150 shown in FIG. 4. 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 continues to be the same for a predetermined time. The output unit 170 may also determine that the work vehicle 30 has stopped when, for example, the distance by which the position represented by the position information of the work vehicle 30 has moved in a predetermined time is equal to or less than a threshold value.

[0064] The above-described embodiment and modified examples are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily changed and / or arbitrarily combined as long as the functions are not impaired. Furthermore, some of the functions described in the embodiment and modified examples may be omitted as long as the necessary functions can be realized. For example, the work management system 1000 may omit the terminal 200 and treat the terminal 200 as a device outside the system. [Explanation of symbols]
