(Operation of work management system)
When the engine of the work device 200 is started, the arithmetic unit 222 of the data transmission device 220 shown in FIG. 3 reads and executes the data transmission program 400, thereby executing part of the work management method. The data transmitter 250 implemented by the arithmetic device 222 acquires the identification information 414 of the transmitter 215 from the transmitter 215 via the receiver 226 . Furthermore, the data transmitter 250 acquires the reception sensitivity 415 from the receiver 226 when the identification information 414 of the transmitter 215 is received. Furthermore, the data transmitter 250 acquires position information 413 of the working device 200 measured by the positioning device 225. The data transmitter 250 stores the acquired identification information 414 of the transmitter 215, reception sensitivity 415, and position information 413 of the working device 200 in the storage device 224 at predetermined time intervals, for example, every minute. do. The data transmitter 250 stores the identification information 414 of the transmitter 215, the reception sensitivity 415, the position information 413 of the working device 200, and the storage time when these are stored in the storage device 224 in association with each other. Further, identification information of the working device 200 representing the working device 200 is also stored in the storage device 224 . When the engine of the work device 200 is stopped, the data transmitter 250 transmits the operating information stored in the storage device 224 to the arithmetic device 120 of the work management device 100.

The computing device 120 of the work management device 100 shown in FIG. 5 reads and executes the work management program 430, for example, when the work management device 100 is started. By executing the work management program 430, the computing device 120 executes the processing shown in FIGS. 8A and 8B, which is part of the work management method. In step S110, the data storage unit 150 implemented by the arithmetic device 120 receives the operation information from the work device 200 and stores the received operation information in the operation data 410.

In step S120, the data correction unit 160 extracts a storage time at which the identification information 414 corresponding to an adjacent storage time changes from the stored operation information. For example, the data correction unit 160 extracts the operation information stored in the operation data 410 shown in FIG. 6 in the order of the storage time indicated by the time information 412. Identification information 414 (hereinafter referred to as extracted identification information) included in the extracted operating information is compared with identification information 414 (hereinafter referred to as adjacent identification information) included in the immediately previously extracted operating information. When the extracted identification information differs from the adjacent identification information, the data correction unit 160 determines that the identification information 414 has changed, and changes the time information 412 (hereinafter referred to as change time information, which is represented by the change time information) corresponding to the extracted identification information. The memory time is called the change memory time).

In the example shown in FIG. 6, "-" in the identification information 414 included in the first operation information 510 indicates that reception is not possible. Unreceivable indicates that the data transmitter 250 of the data transmitter 220 shown in FIG. 4 could not normally receive the identification information 414 from the transmitter 215 during the time interval for storing the operation information. For example, when the identification information 414 is not received in the time interval stored by the data transmitting unit 250, the identification information 414 indicates that it cannot be received. Further, when the receiving sensitivity 415 is smaller than a predetermined value, it is assumed that normal reception has not been possible, and the identification information 414 indicates that reception is impossible.

On the other hand, identification information 414 included in the operation information immediately before the first operation information 510 shown in FIG. 6 represents "A." Therefore, since the identification information 414 included in the first operating information 510 is different from the identification information 414 included in the immediately preceding operating information, the data correction unit 160 extracts the storage time from the time information 412 included in the first operating information 510. Extract.

In step S130 shown in FIG. 8A, the data correction unit 160 determines whether a change storage time at which the identification information 414 changes has been extracted. When the data correction unit 160 extracts the change storage time, it executes the process of step S140. When there is no change storage time at which the identification information 414 changes, the data correction unit 160 ends the process. For example, in the example shown in FIG. 6, the identification information 414 has changed in the first operating information 510, so the data correction unit 160 executes the process of step S140.

In step S140 shown in FIG. 8A, the data correction unit 160 determines whether the changed identification information 414 (hereinafter referred to as changed identification information) represents unreceivable. The data correction unit 160 extracts identification information 414 corresponding to the change storage time extracted from the operation data 410 as the change identification information. When the change identification information, which is the extracted identification information 414, does not indicate unreceivable, the data correction unit 160 executes step S160 shown in FIG. 8B. When the change identification information indicates unreceivable, the data correction unit 160 executes the process of step S150 shown in FIG. 8A. In the example shown in FIG. 6, since the identification information 414 included in the first operation information 510 indicates that reception is not possible, the data correction unit 160 executes the process of step S150.

In step S150 shown in FIG. 8A, the data correction unit 160 corrects the change identification information to identification information 414 corresponding to a storage time adjacent to the change storage time. For example, the data correction unit 160 corrects the identification information 414 indicating unreceivable to the identification information 414 corresponding to the storage time immediately before or after. In the example shown in FIG. 6, the identification information 414 included in the first operating information 510 is corrected to "A", which is the identification information 414 corresponding to the immediately previous storage time, as shown in FIG. Furthermore, the receiving sensitivity 415 included in the first operating information 510 is also corrected to "-86", which is the receiving sensitivity 415 corresponding to the immediately previous storage time. After correcting the identification information 414, the data correction unit 160 returns to step S120 and executes the process.

When the change identification information after the change does not indicate unreceivable, in step S160 shown in FIG. Determine. If the data correction unit 160 determines that the work device 200 is not moving at the extracted change storage time, the data correction unit 160 returns to step S120 shown in FIG. 8A and executes the process. If it is determined that the work device 200 is moving at the extracted change storage time, the data correction unit 160 executes the process of step S170.

For example, the data correction unit 160 determines whether the work device 200 is moving at the change storage time based on the position information 413 corresponding to the change storage time and the position information 413 corresponding to a storage time adjacent to the change storage time. judge. For example, the data correction unit 160 extracts position information 413 corresponding to the change storage time (hereinafter referred to as change position information) from the operation data 410 shown in FIG. 9, and position information corresponding to the storage time adjacent to the change storage time. 413 (hereinafter referred to as adjacent position information). When the extracted change position information and adjacent position information are different, the data correction unit 160 determines that the work device 200 is moving at the change storage time. The data correction unit 160 may determine that the work device 200 is moving at the extracted storage time when the distance between the position represented by the changed position information and the position represented by the adjacent position information is greater than a predetermined threshold. . The adjacent position information may include a plurality of pieces of position information 413 corresponding to a plurality of consecutive storage times including a change storage time. In this case, the data correction unit 160 determines whether the working device 200 has been continuously stopped for a period longer than a predetermined period among the periods represented by a plurality of consecutive storage times. When the working device 200 has not stopped continuously for longer than the predetermined time, the data correction unit 160 determines that the working device 200 is moving at the change storage time.

In the example shown in FIG. 9, in step S120, the data correction unit 160 extracts the second operating information 520 as operating information corresponding to the storage time at which the identification information 414 changes, and in the order of steps S130, S140, and S160. Execute. In step S160, the data correction unit 160 extracts the position information 413 (hereinafter referred to as second position information) included in the second operation information 520 and the storage time (hereinafter referred to as the second storage time) included in the second operation information 520. It is determined that the work device 200 is moving based on the position information 413 of the operation information adjacent to For example, when comparing the second position information and the position information 413 included in the immediately previous operation information, and when the second position information and the position information 413 included in the immediately previous operation information are different, the data correction unit 160 It is determined that the work device 200 is moving. Furthermore, the data correction unit 160 may determine that the work device 200 is moving when the distance from the second position information to the position information 413 included in the immediately preceding operation information is greater than a predetermined distance.

In step S170 shown in FIG. 8B, the data correction unit 160 extracts, based on the operation data 410, a reference period in which the corresponding identification information 414 is the same and is represented by a predetermined number or more consecutive storage times. For example, the data correction unit 160 extracts a reference period that has the same identification information 414, is closest to the change storage time extracted in step S120, and is represented by a predetermined number, for example, 5 or more consecutive storage times. The reference period may be a period before and closest to the change storage time.

In the example shown in FIG. 9, the data correction unit 160 uses a standard that represents the same identification information 414 five times or more consecutively before and closest to the second storage time of the second operating information 520, which is the change storage time. Extract the period. Therefore, the data correction unit 160 extracts the period represented by the second performance information group 525 as the reference period.

In step S180 shown in FIG. 8B, the data correction unit 160 determines whether the work device 200 is continuously moving from the extracted reference period to the change storage time. If there is a period during which the work device 200 is stopped between the reference period and the change storage time, the data correction unit 160 returns to step S120 shown in FIG. 8A and executes the process. When the work device 200 is continuously moving from the reference period to the change storage time, the data correction unit 160 executes the process of step S170 shown in FIG. 8B. The method explained in the process of step S160 is used as the method by which the data correction unit 160 determines the movement of the work device 200. For example, the data correction unit 160 extracts two pieces of operation information whose memory times are adjacent to each other from the period from the reference period to the change memory time, and based on the two extracted pieces of operation information, the data correction unit 160 determines whether the work device 200 has stopped or not. Determine if there are any.

In the example shown in FIG. 9, the data correction unit 160 allows the work device 200 to continuously move between the reference period corresponding to the second operation information group 525 and the second storage time corresponding to the second operation information 520. Determine whether If the data correction unit 160 determines that the work device 200 is continuously moving, it executes the process of step S190.

In step S190 shown in FIG. 8B, the data correction unit 160 corrects the change identification information corresponding to the change storage time to the identification information 414 corresponding to the reference period. Once the change identification information is corrected, the data correction unit 160 returns to step S120 shown in FIG. 8A and executes the process.

In the example shown in FIG. 9, the identification information 414 in the second performance information 520 is corrected to "A", which is the identification information 414 in the second performance information group 525, as shown in FIG. The data correction unit 160 returns to step S120 and executes the process, so that the third performance information 530 is processed in the same manner as the second performance information 520, and as shown in FIG. The identification information 414 of is corrected to "A".

Furthermore, the operation data 410 may receive identification information 414 from different transmitters 215 at the same storage time, as shown in the fourth operation information 540 and the fifth operation information 550 in FIG. Also in this case, the data correction unit 160 extracts the fifth performance information 550 as the performance information corresponding to the storage time at which the identification information 414 changes in step S120 shown in FIG. 8A. Here, the fifth performance information 550 shown in FIG. 11 may be compared with the fourth performance information 540 or with performance information immediately before the storage time indicated by the fourth performance information 540. The data correction unit 160 executes steps S130, S140, and S160 in order, using the storage time corresponding to the extracted fifth operation information 550 (hereinafter referred to as the fifth storage time) as the change storage time.

In step S170 shown in FIG. 8B, the data correction unit 160 represents the same identification information 414 five times or more consecutively before and closest to the fifth storage time of the fifth operating information 550, which is the change storage time. Extract the base period. Therefore, the data correction unit 160 extracts the period represented by the fifth performance information group 555 shown in FIG. 11 as the reference period. The fifth performance information group 555 may be a period including the fourth performance information 540.

The data correction unit 160 executes the processes of steps S180 and S190 shown in FIG. 8B, and as shown in FIG. It is corrected to a certain "A". Thereafter, the data correction unit 160 returns to step S120 and executes the process, and ends the process when no change storage time is extracted.

In this way, the data correction unit 160 of the work management device 100 can correct the operation information of the operation data 410.

When the processes shown in FIGS. 8A and 8B are completed, the work management method determines the work information to be registered in the work data 420 based on the operation data 410 shown in FIG. 5. Specifically, the work determination unit 170 shown in FIG. 4 determines work information, such as work period, work type, work area, etc., based on the corrected operation data 410, and stores the determined work information in data storage. 150. The work determination unit 170 determines, for example, the time from the time when the work device 200 is started to the time when the work device 200 is stopped as the work period. Further, the work determination unit 170 determines the work period based on the time when the work of the work device 200 starts and ends, and the time when the work machine 210 towed by the work device 200 starts and stops, for example. You may. The working period may be determined based on the time when the working device 200 enters the field and the time when it leaves the field. Further, the work period may be determined based on the time when the engine of the work device 200 starts and the time when the work device 200 stops, for example, the engine stops.

The work area is determined based on the position information 413 of the work device 200 during the determined work period. Specifically, the work determination unit 170 determines the work area based on the position information 413 of the operation data 410. For example, the work area is represented by any closed figure including the position represented by the position information 413, such as a polygon or a rectangle. For example, the work area is represented by a figure that surrounds all of the positions represented by the acquired position information 413.

The work type is determined based on the type or model of the work machine 210, for example, the work machine 210, which is towed by the work device 200 during the determined work period. Specifically, the work determination unit 170 determines the work type based on the identification information 414 of the operation data 410 shown in FIG. The data storage unit 150 stores the identification information 414 of the transmitter 215 and the working machine 210 provided with the transmitter 215, such as the type, model, serial number, etc. of the working machine, in association with each other. Further, the data storage unit 150 stores the type, model, serial number, etc. of the work machine 210, for example, the work machine 210, in association with the type of work performed using the work machine 210. The work determination unit 170 determines the work type from the identification information 414 of the operation data 410 and the information stored in the data storage unit 150.

The work information stored in the data storage section 150 in this manner is displayed on the input/output device 310 of the terminal 300 by the display section 350 of the terminal 300 shown in FIG. For example, the terminal 300 generates a request signal for requesting work information from the data storage unit 150 of the work management device 100 in response to a user's operation, for example, an operation for displaying work information. Data storage section 150 generates a response signal representing work information included in work data 420 in response to a request signal from display section 350 of terminal 300, and transmits the response signal to display section 350 of terminal 300. The display unit 350 of the terminal 300 displays work information on the input/output device 310 based on the response signal. By checking the input/output device 310, the user can check the work information determined using the corrected operation information.

Further, the work management device 100 may determine the storage position of the work machine 210 based on the operation data 410. The work machine 210 shown in FIG. 2 is removed from the work device 200 and placed in a storage location. Thereafter, when the work device 200 separates from the work machine 210, the receiver 226 of the data transmitting device 220 provided in the work device 200 separates from the transmitter 215 provided in the work machine 210, and the identification information 414 of the transmitter 215 will no longer be able to receive. For this reason, from the time when the receiver 226 is no longer able to receive the identification information 414 from the transmitter 215, the identification information 414 in the operation data 410 shown in FIG. 2 indicates that it cannot be received. In the operation data 410, the storage position of the work machine 210 is determined based on the position information 413 when the identification information 414 cannot be received continuously for a predetermined period.

For example, when the identification information 414 is continuously unreceivable for a predetermined period in the operating data 410, the data correction unit 160 shown in FIG. 4 acquires the storage time when the identification information 414 changed to unreceivable. The data correction unit 160 acquires position information 413 corresponding to the acquired storage time in the operation data 410 shown in FIG. The information is recorded in the storage unit 150. The data storage unit 150 shown in FIG. 4 transmits storage location information representing the recorded storage location of the work machine 210 in response to a request from the display unit 350 of the terminal 300. The display unit 350 of the terminal 300 can display the storage location of the working machine 210 based on the received storage location information indicating the storage location of the working machine 210.

(Modified example)
The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not impede functionality. For example, in step S160 shown in FIG. 8A, the data correction unit 160 may use any method as long as it can determine whether the work device 200 has moved to the change storage time extracted in step S120. For example, the data correction unit 160 may determine that the work device 200 is moving based on the position information 413 in a plurality of consecutive pieces of operation information including the change storage time. For example, based on the operation data 410, the data correction unit 160 acquires a plurality of position information 413 of the working device 200 during a predetermined period before the change storage time, for example, from the change storage time to 5 minutes before the change storage time. Based on the plurality of pieces of acquired position information 413, the data correction unit 160 determines whether the work device 200 is moving.

For example, when the distance between the two most distant positions among the positions represented by the plurality of acquired position information 413 is greater than a predetermined distance, the data correction unit 160 determines that the work device 200 is moving. do.

Furthermore, the data correction unit 160 extracts all combinations of two pieces of position information 413 whose corresponding storage times are adjacent to each other from the plurality of pieces of position information 413. For all extracted combinations, the distance between the positions represented by the two pieces of position information 413 is calculated. When at least one of the calculated distances is greater than a predetermined distance, the data correction unit 160 may determine that the work device 200 is moving.

In step S180 shown in FIG. 8B, similarly to step S160, the data correction unit 160 determines whether there is a period during which the work device 200 is stopped between the reference period extracted in step S170 and the change storage time. Any method may be used if possible. For example, the data correction unit 160 may determine whether the work device 200 has been stopped for a predetermined period or more, for example, 5 minutes or more, from the reference period to the change storage time. When the working device 200 has been stopped for a predetermined period or longer, the data correction unit 160 determines that there is a period in which the working device 200 has been stopped. When the working device 200 has not stopped for a predetermined period or more, the data correction unit 160 determines that there is no period in which the working device 200 has stopped. Furthermore, the method for determining the movement of work device 200 in step S180 may be the same as or different from the method for determining in step S160.

The storage time of the operating information transmitted by the data transmitter 250 shown in FIG. It may be expressed in any format as long as the corresponding time can be expressed. For example, the stored time may be the time when the identification information 414 of the transmitter 215 was received.

In steps S170 to S190 shown in FIG. 8B, the data correction unit 160 may use any method as long as it can correct the identification information 414 to more likely identification information 414. For example, the data correction unit 160 extracts a period in which the working device 200 continues to move, including the change storage time extracted in step S120, and corresponds to the change storage time based on the identification information 414 for the determined period. The change identification information may be corrected.

Specifically, the data correction unit 160 extracts a period during which the work device 200 continues to move, including the change storage time, based on the operation data 410. The method for determining whether the work device 200 continues to move may be the same as step S160 or step S170 shown in FIG. 8B. Based on the identification information 414 in the extracted period, the data correction unit 160 corrects the change identification information. For example, the changed identification information is corrected to the identification information 414 that was received most by the receiver 226 among the identification information 414 in the extracted period.

The embodiments and modified examples described above are merely examples, and the configurations described in each embodiment and modified example may be arbitrarily changed and/or combined in any manner within a range that does not impede functionality. It's okay. Furthermore, some of the functions described in the embodiments and modified examples may be omitted if the necessary functions can be realized. For example, the display unit 350 shown in FIG. 4 may be realized by the data transmitting device 220. Furthermore, the data storage section 150 and the data correction section 160 may be realized by the data transmission device 220.

The data correction unit 160 may determine that the identification information 414 is correct when the receiver 226 has received the same identification information 414 consecutively for a predetermined number or more. In this case, step S180 shown in FIG. 8B may be omitted.
