Japanese Unexamined Patent Publication No. 2014-178907

When a system operation worker engages in work other than input work, such as inputting necessary information from a terminal for system operation settings, meetings with related parties, confirmation of work procedure manuals, etc. There is. The operation worker may be simply referred to as a worker or an operator below. In addition, the operator may perform a plurality of operation works in parallel from a plurality of terminal devices, and it is not possible to estimate the work time of each of the operations performed in parallel from the operation history of one terminal device alone.

In order to estimate the time that the operator has engaged in a specific operation work with higher accuracy, it is necessary to estimate by considering the information including the operator's action history in addition to the start time and end time of the operator's operation work in the terminal device. There is.

Furthermore, in the operator room where the operator works, multiple operators perform different operation work in the same period, and multiple terminals for the operator to perform the operation work are installed, so that the action history of each operator can be grasped. In order to do so, it is necessary to accurately grasp the working position of the operator. However, Patent Document 1 does not consider accurately grasping the time (required time) required for the actual work in consideration of the operator's work place.

In order to solve the above problems, one of the desirable aspects of the present invention is as follows.
The estimation support system of the present invention manages the information of the operation worker who performed the operation work, the implementation content of the operation work, and the first time information in association with each operation work of the plurality of operation works. An incident information management device that stores information, a location information management device that manages the position information of operation workers together with a second time information, and a terminal device that inputs one of a plurality of operation tasks as an estimation condition. When the incident information management device, the location information management device, and the terminal device are connected via a network and the estimation conditions are input from the terminal device, the incident information is managed in association with the operation work specified by the estimation conditions. The operation worker and the plurality of first time information are extracted, and the extracted operation worker is between the start time and the completion time of the operation work among the extracted plurality of first time information. The first time when the position information corresponding to the second time included in the time zone is extracted from the position information management device and the time required for the operation work specified by the estimation conditions by the operation worker is extracted. It is configured to calculate based on the information and the second time information.

According to the present invention, in addition to the engagement period grasped from the start and end of the operation work of the operation worker, the time actually required for the operation work can be accurately grasped as the required time from the position information of the operation worker. In addition, the operating cost of the target estimation work can be estimated with high accuracy from the time required for the operation work that has been accurately grasped.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an example of an estimation support system that supports the operation of the system. This estimation support system functions as an operator operation cost calculation system or an operation estimation system, for example, depending on its use. The operator means a system operation worker, and means a person in charge of directly operating a machine at the site. In particular, it means a person who performs routine and repetitive work according to a manual or the like, or a person who receives instructions such as work contents and executes the operation as it is.

The operator operation cost calculation system includes a sensor data relay device 100, an incident information management device 120, an operator position information management device 130, an operation cost calculation device 140, and a terminal 150, each of which is a LAN (Local Area Network). ) Is connected via various networks 160 such as the Internet. FIG. 1 has described an example in which the sensor data relay device 100, the incident information management device 120, the operator position information management device 130, the operation cost calculation device 140, and the terminal 150 are configured by separate computing units. All or part of it may be realized by using the resources of cloud computing, or any combination of devices may be realized by one computer. For example, in the case of cloud computing, the incident information management device 120, the operator position information management device 130, and the operation cost calculation device 140 are configured on the cloud side, and the sensor data relay device 100 is configured on-premise. In this case, since the sensor data relay device receives wireless data from the receiver 107 and there are restrictions on the installation location, the sensor data relay device is not configured in the cloud. However, if the repeater 110 is configured to send data via the network, the sensor data relay device 100 can also be configured on the cloud.

The sensor data relay device 100 has a received data storage unit 101, a sensor data information transmission unit 102, and a sensor data information management database 103. The sensor data information management database 103 is composed of at least receiver installation location information, operator-owned sensor information, and sensor data information. The transmission unit 102 transmits the data stored in the sensor data information management database 103 to the incident information management device 120, the operator position information management device 130, and the operation cost calculation device 140 as necessary.

The incident information management device 120 has an incident management database 121 and holds incident information. Incident is work history information with one unit from the start to the end of one operation work content.

The operator position information management device 130 has a sensor data information registration unit 131 and an operator position information management database 132. The operator position information management database 132 holds operator work position information.

The operation cost calculation device 140 has an operation cost calculation unit 141 and a management database 142. The management database 142 includes operator availability information, work content information at the work place, and work unit price information.

The terminal 150 has a condition input screen 151 for inputting an operating cost estimation condition, and a display unit 153 for displaying an operating cost calculation screen 152 for outputting the calculated operating cost.

2A and 2B are hardware configuration diagrams of a computer (sensor data relay device 100, incident information management device 120, operator position information management device 130, operation cost calculation device 140, input / output terminal 150, etc.). be.

The computer is connected to the output I / F201, the input I / F202, the main memory 203, the CPU204, the communication I / F205, and the storage device 206 by a communication line such as a bus connecting them. The CPU 204 reads the program stored in the storage device 206 into the main memory 203 and executes various processes. Hereinafter, the program may be described as if it is an act subject, but it goes without saying that the CPU is actually the subject who executes the program and performs processing.

For example, the sensor data relay device 100 shown in FIG. 2A executes various functions by reading the software stored in the storage device 206 such as a hard disk drive into the memory 203 and executing the CPU 204. For example, the CPU 204 functions as a reception data storage unit 101, and stores data received by the wireless I / F 209 from the receiver 107 via an antenna (not shown) in the storage device 206 as a sensor data information management database. The sensor data information management database stores receiver installation location information, operator-owned sensor information, sensor data information, and the like. The memory 203 includes a RAM, a ROM, and the like. The communication I / F 205 is a communication circuit for communicating with other computers such as the incident information management device 120 through the network 160. The storage device 206 stores application programs, receiver installation location information input via the input device 207 and the network 160, operator-owned sensor information, and the like.

Since the incident information management device 120, the operator position information management device 130, and the operation cost calculation device 140 include common components such as a memory 303, a CPU 304, and a storage device 306 together with the terminal 150, they will be described with reference to FIG. 2 (B). do.

The incident information management device 120 realizes various functions as an incident information management device by reading the software stored in the storage device 306 such as a hard disk drive into the memory 303 and executing the software by the CPU 304. For example, when the incident information 121 is received via the network 160, the CPU 304 stores it in the memory 303, processes the data, and then stores it in the storage device 306 as an incident information management database.

Further, the operator position information management device 130 operates as various functions by reading the software stored in the storage device 306 such as a hard disk drive into the memory 303 and executing the software by the CPU 304. For example, when the operator work position information is received via the network 160, the CPU 304 stores it in the memory 303, performs data processing, and then stores it in the storage device 306 as an operator position information management database.

Further, the operation cost calculation device 140 realizes various functions as an operation cost calculation device by reading the software stored in the storage device 306 such as a hard disk drive into the memory 303 and executing the software by the CPU 304. For example, when the operation cost estimation condition is received from the terminal 150 via the network 160, the incident information, the operator position information, and the like necessary for calculating the operation cost are received via the network. The operating cost is calculated from the received data and output to the output device 308 such as the display of the terminal 150.

If the incident information management device 120, the operator position information management device 130, and the operation cost calculation device 140 do not require the input device 307 and the output device 308, they can be omitted.

Then, the terminal 150 reads the software stored in the storage device 306 such as a hard disk drive into the memory 303, and the CPU 304 executes the software to realize various functions as an input device for estimation conditions and a display device for operating costs. .. For example, the software read from the storage device 306 to the memory 303 outputs the condition input screen of the operation cost to be estimated to the output device 308, and sends the condition input from the input device 307 to the operation cost calculation device 140. The result calculated by the operation cost calculation device 140 is displayed.

FIG. 3 shows the state of the operator room in which the operator 106 performs the operation work, and is a diagram showing that the receiver 107 that receives the sensor data changes depending on the movement of the operator 106. The operator room is 40 to 100 square meters and has 10 to 30 work PCs. Normally, the operator is generally working with 3 to 4 people. Therefore, in order to specify the work performed by the operator from the position information, it is preferable that the position of the operator can be specified with an accuracy of meters (preferably several tens of centimeters).

The sensor 105 attached to the operator transmits a beacon. For example, if Bluetooth (registered trademark) (IEEE 802.15.1) is used for beacon transmission, data can be transmitted from a radius of several meters to several tens of meters. In order to apply it to the operator room, the range of the electric field 109 radiated while suppressing the radio field strength is appropriately set. The receiver installed in each work place determines the received signal strength of the beacon received from the sensor.

The radio wave 109A radiated from the sensor 105 attached to the operator 106 before the movement is transmitted as data including the sensor ID that uniquely identifies the sensor 105, and is received by the receivers 107A and 107B. The receivers 107A and 107B that have received the sensor ID add the receiver ID that uniquely identifies themselves, the time, and the radio field strength value between the sensor and the receiver to the received data, and use the data 111A and 111B as the data 111A and 111B in the repeater 110. Send. That is, the receiver 107 inputs the sensor ID received from the sensor 105 to the receiver ID for identifying itself, the time when the data is received from the sensor, and the reception intensity value of the data from the sensor to the relay device 110. Send as. In this way, the sensor data relay device 100 can manage the sensor data information in which the receiver ID, the reception time, and the radio wave intensity value are set for the sensor ID from each receiver 107.

Next, in the radio wave 109B radiated from the sensor 105 attached to the moved operator 106, the data including the sensor ID is received by the receivers 107C and 107D. The receivers 107C and 107D that have received the sensor ID add the receiver ID that identifies themselves to the sensor ID received from the sensor 105, the time to the received data, and the radio wave strength value between the sensor and the receiver, and are repeaters. Data 111C and 111D are transmitted to 110.

FIG. 4 is a diagram showing an incident information table in the incident information management database 121 of the incident information management device. The incident indicates work history information in which one unit is from the start to the end of one operation work content.

The table shows the time 401 (first time information) when the incident was updated, the incident ID 402 that uniquely identifies the incident, that is, the work content, the work content 403 of the incident that is the operation work content, and the incident status that represents the incident status. 404, the corresponding operator 405 is retained as a set of information. In the table, for example, at the timing when the operator starts the incident work, the incident status is set to "start" from the work PC 108, and the incident information is registered. Further, when the work is completed, the operator updates the incident status of the target incident information from the work PC 108 to "finished". That is, the incident management device 120 receives the entries constituting the table from the work PC 108 via the network 160. In the incident management device 120, the CPU 304 registers "start" and "end" information for each incident of the operator in the incident information table of the storage device 306.

In this incident information table, the incident status for each work content, that is, the start time (start time) and end time (completion time) of the work content corresponding to each incident can be managed as the first time information, and the operator can manage it. The time required for each incident is information that can be grasped as the engagement period. In FIG. 4, item numbers # "1" and "2" are performed by an operator whose incident ID is 00001 and whose work content 403 is "patch application" by "Tanaka". It can be seen that the engagement time of this work is one hour from the update time when the status is "start" to "end". In the item numbers # "7" and "8", the same operator "Tanaka" performs "patch application" which is the same work content for the incident ID 0004. It can be seen that the engagement period of this work is 5 hours from the update time of the status. Such a difference in engagement period occurs, for example, for incident ID00001, the operator concentrated on the work, while for incident ID00004, other work such as meetings with related parties was performed. Probably the result of doing it in a different place. For each incident, the operator updates the incident status, and the work PC can detect the start and end of the incident work and change it automatically.

FIG. 5 is a diagram showing a sensor data information table in the sensor data information management database 103 of the sensor data relay device. The table is a set of receivers including the time 501 when the receiver 107 receives data from the sensor 105, the receiver ID 502 which received the data from the sensor, the sensor ID 503 of the sensor which transmitted the data, and the radio wave strength 504 between the sensor and the receiver. Hold as data. In the sensor data relay device 100, the receiver data received via the wireless I / F 209 is stored in the sensor data information table of the storage device 206 by the reception data storage unit (CPU204). Using this table, the operating cost calculation device 140 can specify the receiver having the maximum radio field strength value between the sensor and the receiver in the same sensor data transmitted from each receiver at the same time. .. The time when the receiver 107 receives data from the sensor 105 is not limited to this example, and can be any interval such as every 5 minutes or 10 minutes for which the position of the operator is desired to be managed. In the sensor data information transmitting unit 102 (CPU204), among the sensor data transmitted from each receiver at the same time, the same is near the receiver showing the data having the maximum radio field strength value between the sensor and the receiver. It is determined that the operator holding the sensor was staying. In the case of FIG. 3, it is determined that the user stayed in the receiver 107A before the worker moved and in the receiver 107C after the worker moved.

FIG. 6 is a diagram showing an operator work position information table in the operator position information management database managed by the operator position information management device. The table shows the time 601 (second time information) when the receiver receives data from the sensor, the work place 602 of the operator who owns the sensor, the operator 603 which owns the sensor, and the sensor owned by the operator. The sensor ID 604 of the above is retained as a set of information. In the operator position information management device 130, the sensor data information registration unit (CPU 304) receives data from the sensor data relay device 100 via the communication I / F 305 and the network 160. The received data includes the time 601 when the receiver received the data from the sensor, the sensor ID, and the work location specified based on the receiver installation location information (see FIG. 7) of the sensor data relay device using the receiver ID as a key. , The operator specified based on the sensor possessed sensor information (see FIG. 8) using the sensor ID as a key is stored in the storage device 306 as an operator position information management device for a set of information. This information is stored in the operator position information management database 132, and the work place of each operator is managed at each time.

FIG. 7 is a diagram showing a receiver installation location information table in the sensor data information management database 103 of the sensor data relay device. The table holds the receiver ID 701 and the work place 702 in which the receiver is installed as a set of information in advance. This information may be input in advance by the input device of the sensor data relay device 100, or may be input by an input means of another computer such as a work PC.

FIG. 8 is a diagram showing an operator-owned sensor information table in the sensor data information management database 103 of the sensor data relay device. The table holds the operator name 801 and the sensor ID 802 of the sensor owned by the operator as a set of information. That is, from the sensor data actually received by the repeater 110 shown in FIG. 5 by using the relationship between the receiver in FIG. 7 and the work place and the relationship between the sensor ID in FIG. 8 and the operator, FIG. 6 Operator work position information can be constructed.

FIG. 9 is a diagram showing an operator availability information table in the management database 142 of the operating cost calculation device. The table manages operator availability information as an operator's schedule, and includes the operator name 901, the start (time) 902 of the period in which the operator can engage in work, and the end (time) 903 of the period in which the operator can engage in work. It is retained as a set of information. That is, the operator availability information means a period during which new work can be assigned to a specific operator.

FIG. 10 is a diagram showing a work content information table at a work place in the management database 142 of the operation cost calculation device. The table holds the operator's work place 1001 and the work content 1002 at the work place as a set of information. With this information, the work content can be specified from the work place.

FIG. 11 is a diagram showing a work unit price information table in the management database 142 of the operation cost calculation device. The table holds the work content 1101 and the hourly unit price 1102 in the work content as a set of information. The information shown in FIGS. 9 to 11 may be input in advance by the input device of the operation cost calculation device 140, or may be input by an input means of another computer such as a work PC.

FIG. 12 is a diagram illustrating a data flow until the sensor data is registered in the operator work position information table of the operator position information management database 132.

The sensor 105 wirelessly transmits the sensor data 112. The receiver A107A has a receiver ID of the receiver A107A, a time when the sensor data 112 is received, and between the sensor 105 and the receiver A107A with respect to the sensor data 112 (including the sensor ID) received from the sensor 105. The data 111A to which the radio wave strength is added is wirelessly transmitted to the repeater 110. Similarly, the receiver B107B receives the receiver ID of the receiver B107B, the time when the sensor data 112 is received, and the sensor 105 and the sensor data 112 (including the sensor ID) received from the sensor 105. The data 111B to which the radio wave strength between the machines B107B is added is wirelessly transmitted to the repeater 110.

Next, the repeater 110 transmits the data 111A received from the receiver A107A and the data 111B received from the receiver B107B to the sensor data relay device 100.
The reception data storage unit 101 of the sensor data relay device 100 stores the data 111A and the data 111B received from the repeater 110 in the sensor data information table of the sensor data information management database 103 in the device.

Next, the sensor data information transmission unit 102 of the sensor data relay device 100 has the maximum radio field strength for each record having the same time as the sensor ID from the sensor data information table of the sensor data information management database 103 in the device. Extract the record.

In addition, the work place is acquired from the receiver installation place information table by using the receiver ID of the same record as a key. The operator is acquired from the operator possessed sensor information table using the sensor ID as a key. The acquired work place and operator are added to the extracted record, and the result is transmitted to the operator work position information table of the operator position information management database 130. In this way, the operator position information table shown in FIG. 6 is managed as the operator position information management database 132.

The sensor data information transmission unit 102 of the sensor data relay device 100 is executed by daily batch processing, and the data range for transmitting the result to the operator work position information table of the operator position information management database 130 is the time of daily batch execution. Only the day before the day is targeted, but the execution interval of batch processing may be longer or shorter than the daily.

FIG. 13 is an example of the message content of the sensor data transmitted from the sensor to the receiver and from the receiver to the repeater. The sensor data 112 wirelessly transmitted from the sensor 105 holds the information of the sensor ID of the sensor 105.

Next, the data 111A includes the sensor ID received from the sensor 105 by the receiver A107A, the receiver ID of the receiver A107A, the time when the sensor data 112 is received, and the sensor 105 with respect to the received sensor data ID. Information indicating the radio wave strength between the receivers A107A is included. Similarly, the data 111B includes the receiver ID of the receiver B107B, the time when the sensor data 112 is received, and the sensor 105 with respect to the sensor ID received from the sensor 105 by the receiver B107B and the ID of the received sensor data. Information indicating the radio wave strength between the receiver B107B and the receiver B107B is included.

FIG. 14 is an example of the estimation condition input screen of the terminal 150. The quotation condition input screen 151 is configured so that the worker inputs the quotation target work and the quotation target work period. You may enter the work completion time (end deadline) instead of the work period to be estimated. In this case, the operator who can work is specified based on the operator's availability information in time for the work completion time. Further, when calculating the time required for the work to be estimated, it is sufficient to input only the target work.

FIG. 15 is an example of the estimation condition input and the operation cost calculation result screen 152 input by the terminal 150.
On the condition input screen 152, the operator inputs the work to be quoted and the work period to be quoted (start date and end date), and presses the "estimate display" button. The estimation result is displayed based on the estimated work and the estimated work period (start date and end date). The work to be estimated may include the type of system and the like in addition to the work content.

<Processing of operating cost calculation device 140>
First, an outline of the processing of the operating cost calculation device 140 will be described with reference to FIGS. 1 and 16.
The operating cost calculation device 140 receives the estimation conditions including the estimation target work input on the condition input screen 151 of the terminal 150 (FIG. 16, step 2001). In this case, the estimated work period may be input if necessary.
From the received estimation conditions, all operators who have performed the work to be estimated in the past and their engagement periods are extracted based on the incident information table shown in FIG. 4 (step 2002). That is, a record related to the same work content as the input target work is extracted from the incident information table of FIG. 4, and the operator who worked on the extracted incident and the status of the record of each incident are extracted as the start time and the end.

Next, the operators who can perform the work during the work period input in step 2001 are extracted based on the operator availability information in FIG. 9 (step 2003). Although the frequency of occurrence is not high in reality in terms of system operation, if the corresponding operator does not exist, the start date and end date of the estimation conditions are changed and input.
For the operators narrowed down in step 2003, the engagement period related to one incident is calculated from the start time and end time of the record having the same incident ID (step 2004).

The actual work time required for the estimation work is obtained from the incident information in FIG. 4 and the operator work position information in FIG. 6 (step 2005). Specifically, for the narrowed down operators, all the entries with the same work contents as the work to be estimated are extracted from the incident information table, and the engagement period is calculated for each incident. Since the time required for each operator to perform each incident is grasped as the engagement period from the update time registered in the incident information table, it is not possible to directly grasp the time taken for the actual work. That is, during the work period, the operator may be away from the work place due to a meeting with related parties or the like.

Therefore, in this embodiment, the time required for the work to be estimated by each operator is grasped based on the operator work position information stored in the operator position information management device 130. The actual work time is grasped as the required time with reference to the operator work position information shown in FIG.

For example, in the incident information of FIG. 4, it is grasped that the operator "Tanaka" takes one hour for the work content "patch application" in the item numbers # "1" and "2", but the operator work position in FIG. According to the information, the time spent at the work place "work place A" ("patch application" based on the work contents at the work place in FIG. 10) is 5 minutes from 0:00 to 0:05 on 1/10/2018. Is grasped. From the incident information in FIG. 4, it was grasped that the required time was 1 hour, but by grasping the time when the operator was at the work place within the update period of the incident status of the incident information, the actual time required for the work was grasped. It can be understood that it is 5 minutes.

The operation cost calculation device of FIG. 20 will be described in detail with reference to a diagram showing an outline of calculating the required time for the operator to perform the work related to the incident.
Operator A starts incident ID00001 at 9:00 on April 1st and ends at 13:00. This data is stored in the incident information table and is managed as the engagement period of the incident ID 00001 of the operator A. However, the operator A actually performed the incident ID00001 for a total of 2 hours, 1 hour from 9:00 to 10:00 and 1 hour from 12:00 to 13:00 at the work place A. It can be grasped from the information. Further, it can be seen that the operator A is performing different work at the work place B between 10 o'clock and 11 o'clock, and further different work is being performed at the work place C between 11 o'clock and 12 o'clock. In this way, it is possible to accurately grasp the time required for the work of the incident ID 00001 from the incident information and the position information of the operator actually grasped from the sensor data.

The data # 1 and # 2 indicating that the operator A shown in FIG. 20 is located at the work place A shall be determined from each record of the operator work position information (FIG. 6) created by the above method from the sensor data. Can be done. Although the dates of FIGS. 20 and 6 are different, the record numbers # 1 and 2 are information corresponding to # 1 and 2 of FIG. 20. Based on each record of the operator work position information of FIG. 6, the work time during which the operator's incident work as shown in FIG. It can be grasped with.

In this way, the total time that the operator was actually in the workplace within the incident status update period is the time required for one incident.

From the total time required for each incident and the number of incidents, the average actual work time for each operator for the same work is calculated (step 2006).
By multiplying the average actual work time by the work unit price shown in FIG. 11, an estimate reflecting an accurate cost can be created (step 2007). The operation cost is calculated by calculating the total required period of the past estimated work of all the operation operators from the incident information and the operator work position information, and multiplying the average work actual time per estimated work by the work unit price.

Next, the calculated operating cost is displayed on the terminal 150 (step 2008). When there are a plurality of operation works to be estimated, steps 2002 to 2007 of FIG. 16 are performed for all the operation works, the operation costs are totaled, and the total result is displayed on the operation cost calculation result screen 152.

FIG. 17 is a processing flow diagram of the received data storage unit 101 in the sensor data relay device 100.
The reception data storage unit 101 receives the sensor data 111 from the repeater 110 (step 1701), and stores the data in the sensor data information table of the operator position information management database 132 (step 1702). Then, the process returns to step 1701.

FIG. 18 is a processing flow diagram of the sensor data information transmission unit 102 in the sensor data relay device 100.
First, the sensor data information transmission unit 102 extracts a record having the same sensor ID 503 and time 501 from the sensor data information table of the operator position information management database 132 (step 1801).
Next, if there are multiple records with the same sensor ID 503 and the same time 501 and the same radio field strength 504 in the records extracted in step 1801 (step 1802), the record with the maximum radio field strength is left and the other records are left. Delete the record (step 1803).
Next, using the receiver ID 502 and sensor ID 503 of the extracted records as search keys, the work place 702 is acquired from the receiver installation location information table, and the operator 801 is acquired from the operator possessed sensor information table (step 1804).
Next, the result of step 1804 is transmitted to the operator work position information table of the operator position information management database 132 (step 1805), and the process is terminated.

FIG. 19 is a processing flow diagram of the sensor data information registration unit 131 in the operator position information management device 130.
First, the sensor data information registration unit 131 receives the transmission result of step 1805 of the sensor data information transmission unit 102 (step 1901).
Next, the data received in step 1901 is registered in the operator work position information table of the operator position information management database 132 (step 1902).
According to this embodiment, even when the operator engages in work other than input work, such as meetings with related parties and confirmation of work procedure manuals during work, it is necessary to perform the work to be estimated. The required time can be accurately grasped from the position information of the operator.

In addition, even in an environment such as an operator room where multiple operators perform different operation work during the same period or a plurality of terminals on which the operator performs operation work are installed, which cannot be grasped only by entry / exit management, the operator room It is possible to accurately grasp the work position of the operator, and it is possible to accurately grasp the time required for the work, which could not be accurately grasped from the engagement period.

In addition, by accurately grasping the required time for the work, the operating cost of the work to be estimated can be calculated.

Furthermore, an accurate estimate of operating costs can be calculated in consideration of the operator's free time.

<Other application examples>
As a means for grasping and managing the position of the operator, in addition to the method using the sensor described in the first embodiment, the sensor 105 is provided with a GPS function to obtain sensor data including position information. In this case, the receiver 107 becomes unnecessary, and the data received by the repeater 110 from the sensor includes the data including the sensor ID and the sensor position information. The location information is managed instead of the receiver IDs of FIGS. 5 and 7. The operation related to the receiver 107 in FIG. 12 is also unnecessary, and the repeater receives data directly from the sensor.

According to the example using this GPS function, it is effective in the case of a work area larger than the operator room.

Further, when there is one work PC in the operator room and one work is performed for each work PC, entry / exit management data can be used instead of the sensor data. In this case, the sensor data of FIG. 5 manages the entry / exit time and the operator who is the entry / exit person.
