According to the work performance management system of the present invention, the work performance management system includes an identification information storage medium that stores medium identification information and is carried by the worker, and a management device that manages work performance. The identification information storage medium includes a beacon signal receiving unit that receives a beacon signal output by a beacon terminal provided for each work equipment, and a work state of the worker determined based on the received beacon signal. and beacon terminal identification information for transmitting beacon terminal identification information in which beacon terminal identification information included in the received beacon signal and the medium identification information are associated with each other based on the work state determination result. and a transmission unit, wherein the management device includes a beacon terminal identification information reception unit that receives the beacon terminal identification information, and based on the beacon terminal identification information, the worker, the work equipment, and work start. The problem is solved by having a work performance information generation unit that generates work performance information in which time and work end time are associated with each other, and a work performance information output unit that outputs the work performance information.

This eliminates the need for cable laying work to connect the work equipment and the management device, so the work management system can be easily introduced.
The identification information storage medium determines the working state of the worker, and the management device does not determine the working state of the worker. Therefore, the processing load on the management device is reduced, and it becomes possible to centrally manage the work results of a large number of workers.
Then, work performance information is generated in which the worker, work equipment, work start time, and work end time are associated with each other. That is, since the work results are managed in association with the work equipment, it is possible to grasp the work results simply with less information than in the case of managing the work results based on the worker's flow line.

It is preferable to As a result, the work performance information can be grasped from two viewpoints, one for each worker and one for each work facility.

Moreover, it is preferable that the work performance management system has the beacon terminal, and the beacon terminal has an output level setting unit for setting the output level of the beacon signal. As a result, it is possible to appropriately determine the work status of work equipment and work areas of different sizes, so that more accurate work performance information can be generated.

Also, the identification information storage medium is preferably a card-type identification information storage medium. As a result, the worker can hang the identification information storage medium from his neck or store it in the pocket of his work clothes, so that the worker can easily carry the identification information storage medium without lowering the working efficiency of the worker. be able to.

Further, the above-mentioned problem is a work result management method carried out by an identification information storage medium in which medium identification information is stored and carried by a worker, and a management device for managing work results, wherein the identification information storage a step in which a medium receives a beacon signal output by a beacon terminal provided for each work facility; and a step in which the identification information storage medium determines the working state of the worker based on the received beacon signal. a step in which the identification information storage medium transmits beacon terminal identification information in which the medium identification information is associated with the beacon terminal identification information included in the received beacon signal based on the determination result of the working state; a step in which the management device receives the beacon terminal identification information; and a step in which the management device associates the worker, the work equipment, and work start time and work end time based on the beacon terminal identification information.

This eliminates the need for cable laying work to connect the work equipment and the management device, so the work management system can be easily introduced.
The identification information storage medium determines the working state of the worker, and the management device does not determine the working state of the worker. Therefore, the processing load on the management device is reduced, and it becomes possible to centrally manage the work results of a large number of workers.
Then, work performance information is generated in which the worker, work equipment, work start time, and work end time are associated with each other. That is, since the work results are managed in association with the work equipment, it is possible to grasp the work results simply with less information than in the case of managing the work results based on the worker's flow line.

Since the beacon terminal 14 repeatedly transmits the beacon signal at a predetermined time period, the card-type communication device 22 receives the beacon signal multiple times. Then, the card-type communication device 22 calculates the average RSSI value of the beacon signals received a plurality of times. Specifically, the card-type communication device 22 calculates an average value excluding outliers including at least the maximum value and the minimum value from the RSSI of the beacon signals received a plurality of times (hereinafter referred to as the average RSSI). ). An outlier is a value that is extremely large or extremely small relative to other values, and in the case of this embodiment, RSSI or The RSSI shows an extremely small value.

Then, the card-type communication device 22 subtracts the above-described average RSSI from the transmission signal level transmitted by the beacon terminal 14, so that the amount of attenuation of the beacon signal between the beacon terminal 14 and the card-type communication device 22 (attenuation amount ). The card-type communication device 22 estimates the distance between the beacon terminal 14 and the card-type communication device 22 based on the attenuation amount.
However, the distance estimation method is not limited to the method described above. It is sufficient if the distance between the card-type communication device 22 and the mechanical equipment 11 can be estimated based on the RSSI of the beacon signal.

Subsequently, the card-type communication device 22 determines the working state of the worker 20 based on the distance estimation result. Specifically, when the estimated distance is within a predetermined distance (threshold value), it is determined that the worker 20 is working. The predetermined distance (threshold value) is a distance for determining that the worker 20 is positioned at a position where the machine equipment 11 can be operated to perform work. In this embodiment, the threshold is 1 meter.

FIG. 6 is a diagram showing the concept of work state determination processing.
FIG. 6 shows a machine 11, a worker 20a who operates the machine 11, and a worker 20b who is away from the machine 11 and observes the state of the machine 11 on the pedestrian lane 16. FIG. A dashed line indicates a position at a distance of 1 meter from the beacon terminal 14 . A reference numeral 17 denotes an area inside the dashed line, that is, an area within a threshold value, and an operation area 17 in which the worker 20 can operate the mechanical equipment 11 to perform work. Since the worker 20a is positioned within the operation area 17 within the threshold, the card-type communication device 22 carried by the worker 20a determines that the worker 20a is working. On the other hand, the card-type communication device 22 carried by the worker 20b determines that the worker 20b is not working.

Here, it is preferable that the card-type communication device 22 has a threshold value setting unit capable of setting a threshold value for determining the work state. For example, the threshold value of the card-type communication device 22 of the worker 20a who operates the machinery 11 is set to 1 meter. On the other hand, the threshold value of the card-type communication device 22 carried by the worker 20b who supports the worker 20a by giving advice or the like at a position a little away from the mechanical equipment 11 is set to a value larger than 1 meter. In this way, by making it possible to set a different threshold for each card-type communication device 22, a threshold corresponding to the attributes of the worker 20 carrying the card-type communication device 22 (responsible task, work content, type of job, position, etc.) can be set, and the working state can be determined appropriately.
The threshold value may be input via the input unit 24 of the card-type communication device 22 described above, or may be input by writing to the non-volatile memory of the control unit 23 from the outside.

When the card-type communication device 22 receives beacon signals from a plurality of beacon terminals 14 respectively installed in a plurality of mechanical equipment 11, the one mechanical equipment 11 in which the beacon terminal 14 at the closest distance is installed, Identify as work target equipment. Specifically, when receiving a plurality of beacon signals, the card-type communication device 22 determines the beacon terminal 14 with the highest average RSSI of the received beacon signals as the beacon terminal 14 at the closest distance.

FIG. 7 shows a state in which a plurality of machines 11 are installed around a worker 20, and a card-type communication device 22 carried by the worker 20 receives beacon signals from a plurality of beacon terminals 14. ing. In the example shown in FIG. 7 , four machines 11 are installed around the worker 20 , and one beacon terminal 14 is attached to each machine 11 . At this time, the card-type communication device 22 carried by the worker 20 receives beacon signals from the four beacon terminals 14 . Then, the card-type communication device 22 identifies the mechanical equipment 11 to be worked on based on the beacon signal with the largest average RSSI, and determines whether or not the identified mechanical equipment 11 is being operated to perform the work. .

Thus, the card-type communication device 22 determines that the worker 20 is working when the distance from the beacon terminal 14 is within 1 meter based on the average RSSI. Then, when beacon signals are received from a plurality of beacon terminals 14, the beacon terminal 14 with the highest average RSSI is determined, and it is determined that the machine equipment 11 to which the beacon terminal 14 is attached is being operated for work. do.

When determining that the worker 20 is working, the card-type communication device 22 transmits beacon terminal identification information including the beacon ID and the card ID to the work performance management server 50 . While it is determined that the worker 20 is operating the machinery 11 to perform work, the card-type communication device 22 repeats the beacon terminal identification information at regular time intervals (every 10 seconds) and manages work results. Send to server 50 .
Since the beacon ID and card ID are transmitted by wireless communication from the card-type communication device 22 carried by the worker 20, there is no need for cable laying work when introducing the present system 1 into a factory or the like. Moreover, the card-type communication device 22 determines the work status of the worker 20 , and the work result management server 50 does not determine the work status of the worker 20 . Therefore, the processing load on the work performance management server 50 is reduced, and the work performance of many workers 20 can be centrally managed.

When the worker 20 leaves the front of the mechanical equipment 11 and exits the operation area 17, the card-type communication device 22 determines that the worker 20 is not working, and stops transmitting the beacon terminal specifying information.
When determining that the worker 20 is not working, the card-type communication device 22 repeatedly transmits the card ID to the work result management server 50 at regular time intervals. That is, when determining that the worker 20 is not working, the card-type communication device 22 transmits the card ID without transmitting the beacon terminal specifying information.

Next, the relationship between a series of work performed by the worker 20 and the work performance information generated by the work performance information generation unit 56 will be described.
FIG. 8 shows the relationship between the work flow when the worker 20 operates a plurality of machines 11 to perform work during working hours of the day, and the work performance information generated for the work performed. . FIG. 8 shows that the work area 10 is equipped with four machines 11: a lathe machine, a cutting machine, an NC lathe machine, and a press machine. The worker 20 used the lathe machine, the cutting machine, and the press machine in order to finish the day's work. Specifically, when the work of the day starts, the worker 20 (worker A) first moves to the front of the lathe machine and operates the lathe machine from 9:23 to 10:45. did

When the worker A moves to the front of the lathe machine, the card-type communication device 22 carried by the worker A receives the beacon signal output by the beacon terminal 14 attached to the lathe machine, and the worker 20 Determine that you are working. The card-type communication device 22 transmits beacon terminal identification information including a beacon ID and a card ID to the work performance management server 50 . Then, the card-type communication device 22 repeats transmission of the beacon terminal identification information in a predetermined time cycle. The work performance management server 50 receives the beacon terminal identification information and stores it in the work performance storage unit 60 together with the reception time.

When the work is finished at 10:45, the worker A leaves the lathe and moves to another place. The card-type communication device 22 carried by worker A determines that worker A is not working. At this time, the card-type communication device 22 stops transmitting the beacon terminal identification information to the work performance management server 50 . Then, the card-type communication device 22 repeatedly transmits the card ID to the work result management server 50 at predetermined time intervals. The work result management server 50 receives the card ID and stores it in the work result storage unit 60 together with the reception time.

Next, worker A arrives in front of the cutting machine at 10:55. Then, the card-type communication device 22 receives a beacon signal output from the beacon terminal 14 attached to the cutting machine, and determines that the worker A is working. The card-type communication device 22 transmits the beacon terminal identification information to the work performance management server 50 . Then, the card-type communication device 22 repeats transmission of the beacon terminal identification information in a predetermined time cycle. The work performance management server 50 receives the beacon terminal identification information and stores it in the work performance storage unit 60 together with the reception time.

The work using the cutting machine ends at 11:25, and worker A leaves the front of the cutting machine and moves to another place. The card-type communication device 22 carried by worker A determines that worker A is not working. The card-type communication device 22 stops transmitting the beacon terminal identification information to the work performance management server 50 . Then, the card-type communication device 22 repeatedly transmits the card ID to the work result management server 50 at predetermined time intervals. The work result management server 50 receives the card ID and stores it in the work result storage unit 60 together with the reception time.

Subsequently, at 13:10, worker A moves in front of the press machine and starts work by operating the press machine. As described above, the card-type communication device 22 receives the beacon signal transmitted by the beacon terminal 14 attached to the press machine and determines that the worker A is working. The card-type communication device 22 then transmits the beacon terminal identification information to the work performance management server 50 . The work performance management server 50 receives the beacon terminal identification information and stores it in the work performance storage unit 60 together with the reception time.

The work using the press machine ends at 14:05, and worker A leaves the press machine and leaves the work area 10 . The card-type communication device 22 carried by worker A determines that worker A is not working. The card-type communication device 22 stops transmitting the beacon terminal identification information to the work performance management server 50 . Then, the card-type communication device 22 repeatedly transmits the card ID to the work result management server 50 at predetermined time intervals. The work result management server 50 receives the card ID and stores it in the work result storage unit 60 together with the reception time.
When worker A finishes work for the day and turns off the card-type communication device 22 or connects the card-type communication device 22 to the charging stand, the card-type communication device 22 sends a message to the work result management server 50. Stop sending the card ID.

When the manager of the work area 10 operates the input unit 52 of the work result management server 50 to request the display of work result information, the work result management server 50 generates the work result information. It outputs work performance information to the display unit 53 . The manager of the work area 10 may operate the input section of the work management terminal 80 to request display of the work performance information. At this time, the work performance information is output and displayed on the display section of the work management terminal 80. FIG.

Specifically, based on the beacon ID and the card ID, the work performance information generation unit 56 of the work performance management server 50 stores a record related to the work performance performed by the worker A operating the lathe processing machine in the work performance storage unit. Extract from 60. Then, among the extracted records, the work performance information generation unit 56 determines the reception time of the first record among the records consecutive at a predetermined time interval as the work start time. Similarly, the work performance information generation unit 56 determines the reception time of the last record among the extracted records that are consecutive at predetermined time intervals as the work end time. The work performance information generation unit 56 refers to the machine equipment information storage unit 58 and converts the beacon ID into the machine equipment name, and also refers to the worker information storage unit 59 to convert the card ID into the worker name. Generate performance information. Here, the work performance information of the work performed by the worker A using the lathe machine from 9:23 to 10:45 is generated.

Subsequently, the work performance management server 50 generates work performance information about the work performed by the worker A by operating the cutting machine. Specifically, the work performance information of the work performed by the worker A using the cutting machine from 10:55 to 11:25 is generated.
Finally, the work performance management server 50 generates work performance information about the work performed by the worker A by operating the press machine. Specifically, the work performance information of the work performed by the worker A using the press machine from 13:10 to 14:05 is generated.

During the time from 10:45 to 10:55 until the worker 20 leaves the lathe and moves in front of the cutting machine, the worker 20 does not enter the operation area 17, so the work performance information is not generated. Similarly, work performance information is not generated for the time from 11:25 to 13:10, which is the time when the worker 20 leaves the cutting machine and moves in front of the pressing machine. Also, the work performance information is not generated for the time from leaving the press machine and exiting the operation area 17 to finishing the work for the day.

Thus, the work performance management server 50 generates work performance information based on the beacon terminal identification information received from the card type communication device 22 . The work performance management server 50 can also generate information about working hours based on the card ID received from the card-type communication device 22 .

Next, the work performance information generation process and the work performance information output process executed by the work performance management server 50 will be described.
FIG. 9 shows a flow in which the control unit 51 of the work performance management server 50 generates and outputs work performance information. Steps S11 to S15 indicate work result information generation processing by the work result information generation unit 56, and steps S16 to S22 indicate work result information output processing by the work result information output unit 57. FIG.
First, the control unit 51 determines whether or not an operation for outputting and displaying work performance information has been performed (step S11). That is, whether or not the manager of the work area 10 has operated the input unit 52 of the work result management server 50 or the input unit of the work management terminal 80 to display the work result information. determine whether

If it is determined that the output display operation has not been performed (step S11: No), the process waits until the output display operation is performed.
On the other hand, when it is determined that the output display operation has been performed (step S11: Yes), the control unit 51 reads the record of work performance from the work performance storage unit 60 of the storage unit 55 (step S12).

Subsequently, the control unit 51 determines the work start time and the work end time based on the reception time information of the work performance record (step S13). Specifically, based on the beacon ID and the card ID in the record of the work performance read in step S12, the control unit 51 controls the work performed by the one worker 20 by operating the one mechanical equipment 11. Extract such records. The control unit 51 determines the reception time of the first record among the extracted records that are consecutive at predetermined time intervals as the work start time. Similarly, the control unit 51 determines the reception time of the last record among the extracted records that are consecutive at predetermined time intervals as the work end time. The control unit 51 repeats this process for all other mechanical equipment 11 and workers 20 .

Then, the control unit 51 refers to the mechanical equipment information storage unit 58 of the storage unit 55 and converts the beacon ID into the mechanical equipment name (step S14). At the same time, the control unit 51 acquires information on the installation area. Similarly, the control unit 51 refers to the worker information storage unit 59 and converts the card ID into the worker name (step S15).
Through the above process, the work performance information including the machine equipment name, worker name, work start time and work end time is generated.

Next, the control unit 51 outputs the worker performance information, which is the work performance information for each worker 20, based on the operation input by the manager, or outputs the equipment operation performance information, which is the work performance information for each machine equipment 11. It is determined whether or not to output (step S16). However, either the worker performance information or the equipment operation performance information may be output based on a predetermined setting.

When determining to output the worker performance information, the control unit 51 generates the worker performance information (step S17). Specifically, the control unit 51 repeats the process of extracting only the work performance information related to one worker 20 from among the work performance information generated in step S15 for all other workers 20. Generate worker performance information.
Subsequently, the control unit 51 outputs the worker performance information (step S18). A worker performance screen 61 for outputting and displaying worker performance information will be described later with reference to FIG.

Subsequently, the control unit 51 determines whether or not the facility operation record button 69 (see FIG. 10) has been pressed. If it is determined that the facility operation record button 69 has been pressed (step S19: Yes), the process proceeds to step S20. On the other hand, if it is determined that the facility operation record button 69 has not been pressed, the process is terminated.

When it is determined in step S16 that the facility operation record information is output, or when it is determined in step S19 that the facility operation record button 69 has been pressed, the control unit 51 generates the facility operation record information (step S20 ). Specifically, the control unit 51 repeats the process of extracting only the work performance information related to one mechanical equipment 11 from the worker performance information generated in step S15 for all the other mechanical equipment 11. to generate equipment operation record information.
Subsequently, the control unit 51 outputs the machine equipment performance information (step S21). The equipment operation result screen 71 for outputting and displaying the equipment operation result information will be described later with reference to FIG. 11 .

Subsequently, the control unit 51 determines whether or not the operator performance button 72 (see FIG. 11) has been pressed. If it is determined that the operator performance button 72 has been pressed (step S22: Yes), the process proceeds to step S17. On the other hand, if it is determined that the operator performance button 72 has not been pressed, the process is terminated.

Next, the worker performance screen 61 output and displayed in step S18 will be described.
FIG. 10 shows a worker performance screen 61 displaying worker performance information. The worker track record screen 61 is output and displayed on the display unit 53 of the work track record management server 50, or is output to the work management terminal 80 connected to the Internet line NW via the communication unit .

The weekly display button 67 is a button for displaying the work performance information displayed in the work performance display 62 on a weekly basis. That is, when the weekly display button 67 is pressed, the work performance information for one week is displayed in the work performance display 62 .
The monthly display button 68 is a button for displaying the work performance information displayed in the work performance display 62 on a monthly basis. That is, when the monthly display button 68 is pressed, the work performance information for one month is displayed in the work performance display 62 .

The equipment operation result button 69 is a button for switching the display screen from the worker result screen 61 to the equipment operation result screen 71 for output display. The work performance information output unit 57 can switch between the worker performance screen 61 and the equipment operation performance screen 71 and output one of the display screens.

Moreover, the beacon terminal 14 may be attached to the mechanical equipment 11 installed in the off-limits area 12 . The mechanical equipment 11 installed in the off-limits area 12 is, for example, an aerial work platform. In this case, the mechanical equipment information storage unit 58 described with reference to FIG. 5A stores "aerial work vehicle" as the mechanical equipment name and "no-entry area" as the installation location.

In addition, near the entrance/exit of the work area 10, a preparatory work area 13 is set in which the worker 20 performs preparatory work before entering the work area 10. As shown in FIG. The worker 20 is obliged to wash his/her hands in the preparation work area 13 before entering the work area 10 .

The beacon signals transmitted by the beacon terminals 14 installed in the off-limits area 12 and the preparation work area 13 must be receivable by the card-type communication device 22 carried by the worker 20 in the area. Therefore, it is preferable that the beacon terminal 14 has an output level setting unit for setting the output level of the beacon signal according to the respective sizes of the restricted area 12 and the preparation work area 13 . The output level setting unit may be a setting button provided on the beacon terminal 14, or may be a non-volatile memory capable of writing output level setting values from the outside.

As a result, the administrator can grasp that the unscheduled worker 20 has entered the off-limits area 12, so that it is possible to determine whether or not the access to the off-limits area 12 is sufficiently restricted. can.

Although the notification display 74 is output and displayed when the worker 20 performs work in the off-limits area 12 or the preparation work area 13, the target of the notification display 74 is not limited to this. Information useful for the manager of the work area 10 can be notified and displayed. For example, a notification display 74 is output for the machine equipment 11 whose operation rate is lower than a predetermined threshold value, and the manager is informed of the operation of the machine equipment 11. May encourage review.

In addition, the work result information output unit 57 has been described as outputting and displaying the worker result screen 61 and the equipment operation result screen 71 on the display unit 53 of the work result management server 50, but the work result information output unit 57 does not transmit to the remote work management terminal 80. can be output as

Next, a second modification of the system 1 will be described.
In the above-described embodiment, one beacon terminal 14 is attached to one mechanical equipment 11 , but a plurality of beacon terminals 14 may be attached to one mechanical equipment 11 . At this time, a plurality of beacon terminals 14 attached to one piece of equipment 11 transmit a common beacon signal. Therefore, it is possible to appropriately manage the work performed by operating the large-sized mechanical equipment 11 having a wide operation area 17 and the large-sized mechanical equipment 11 having a plurality of operation areas 17 .

FIG. 15 shows the arrangement of mechanical equipment 11 according to the second modification. Two large machines 11 are installed in the work area 10 . Each machine 11 has a wide operating area 17 covered by the transmission areas of three beacon terminals 14 attached to the machine 11 . Three beacon terminals 14 attached to one machine 11 output a common beacon signal. That is, three beacon terminals 14 attached to one machine 11 have a common beacon ID and transmit this as a beacon signal.

When the operator 20 moves to the front of the mechanical equipment 11 to operate the mechanical equipment 11 to perform work, the worker 20 enters the operation area 17 . At this time, the card-type communication device 22 carried by the worker 20 receives the beacon signal transmitted by the beacon terminal 14, determines that the worker 20 is working, and transmits the beacon terminal specific information to the work result management server. 50.
