(Use of barcode reader)
Here, a method of checking the connection state when a barcode reader is used as the measurement input device 6 connected to the portable information terminal 3 shown in FIG. 2 in step S105 of the flowchart shown in FIG. 4 will be described.

First, when checking using a bar code reader, a bar code or a two-dimensional code is attached in advance to each terminal and electric cable of the terminal block arranged on the switchboard in the plant. To do. That is, identification information is given in advance to the terminal and the electric cable.
Thus, by using a barcode reader as the measurement input device 6, the operator 7 is attached to each component in the terminal block to be checked when performing a connection check on the connection list screen 80 shown in FIG. 8. The connection status can be checked by reading the barcode.

For this purpose, the worker 7 first reads the barcode attached to the terminal of the terminal block with a barcode reader. This bar code reader includes a function for decoding the read bar code, and an ID for identifying a terminal obtained by decoding the read bar code is temporarily stored in the information portable terminal 3. Subsequently, the worker 7 reads the barcode attached to the electric cable connected to this terminal with a barcode reader. The read bar code is similarly decoded to obtain an ID for identifying the electric cable.
The information portable terminal 3 that has acquired the ID for identifying the terminal and the ID for identifying the electric cable connected thereto determines whether there is an error in the connection between the terminal and the electric cable based on the information displayed on the connection list screen 80. To do. As a result, if the connection state is correct, “OK” is displayed in the area indicated by reference numeral 87. By repeating the same procedure, it is possible to check the connection state of the electric cable connected to the terminal block after the restoration work is completed.

In this way, by checking the connection state using the barcode reader, it is possible to reduce an artificial check mistake caused by the operator 7 visually observing the connection list screen 80 and the connection state in the field. Can do.
Further, by attaching identification information such as a barcode or a two-dimensional code to components in the switchboard, the identification information is read by a barcode reader and stored in the plant specification DB 911 of the database server 9. In addition, it is possible to easily search for specification information (such as cable manufacturing date, connection destination, deterioration information) of equipment used in the switchboard.

  It is also conceivable that deterioration of an electric cable or the like is confirmed on the spot by connecting a deterioration diagnosis probe such as an ultrasonic diagnosis probe as the measurement input device 6.

(Second Embodiment)
Next, a detailed description will be given of a second embodiment in which the work management system according to the present invention is applied to work management of a worker working in a radiation management area.

(Work management system configuration)
The components constituting the work management system in this embodiment are almost the same as the work management system of the first embodiment shown in FIG. 1, and therefore different parts from the work management system of the first embodiment. This will be described in detail (see FIG. 1 as appropriate).

In this embodiment, the worker 7 carries an exposure dose management apparatus that measures his / her exposure dose as a new component. Here, FIG. 11 is an example of a functional block diagram of the exposure dose management apparatus 110. The worker 7 carries the exposure dose management device 110 on a part of the body (as an optimal place, the left chest for men and the lower abdomen for women).
Referring to FIG. 11, the exposure dose management apparatus 110 mainly includes a sensor control unit 111, a dose sensor 112 that measures the exposure dose, and an antenna 119 connected to the sensor control unit 111. Further, the sensor control unit 111 includes a work memory 113, a program memory 114, a control circuit 115, an information transmission control circuit 116, an identification information recording circuit 117, and a timer circuit 118.
The timer circuit 118 passes the time interval for acquiring information from the dose sensor 112 to the control circuit 115. The work memory 113 temporarily stores information sent from the dose sensor 112. The identification information recording circuit 117 records an ID number for individual recognition of the exposure dose management apparatus 110. The information transmission control circuit 116 transmits information obtained by the exposure dose management apparatus 110 from the antenna 119 to the portable information terminal 3 carried by the worker 7. The control circuit 115 processes information sent from the dose sensor 112 in accordance with a program stored in the program memory 114 and transmits the information from the information transmission control circuit 116 to the information portable terminal 3.

The exposure dose management apparatus 110 temporarily stores information on the exposure dose sent from the dose sensor 112 in the work memory 113. The information on the exposure dose is sequentially transmitted from the antenna 119 of the exposure dose management apparatus 110 to the information portable terminal 3 of the worker 7 who is working, whereby the worker 7 uses his / her information portable terminal 3 to Changes in exposure dose can be confirmed in real time.
Further, the information on the exposure dose transmitted to the information portable terminal 3 is transmitted from the data transfer device 4 connected to the information portable terminal 3 to the database server installed in the office 12 via the Internet 20.

  Next, FIG. 12 shows an example of a functional block diagram of the database server of this embodiment. The database server 9 ′ shown in FIG. 12 stores information on the exposure dose of the worker 7 measured by the exposure dose management apparatus 110 in addition to the components of the database server 9 (see FIG. 3) of the first embodiment. It can be seen that it is configured to include an exposure dose management means 912 to be managed and an exposure dose information DB 913 storing information on the exposure dose of each worker 7 and information obtained by processing it.

The dose information DB 913 stores dose information for each worker 7 measured by the dose management apparatus 110. For example, as shown in Table 2 below, the dose information in units of time is stored in a table format. Stored.
The dose information shown in Table 2 is recorded in units of hours, but it is also possible to store dose information in minutes.

In order to make this table easier to see during the work, the exposure dose management means 912 of the database server 9 ′ can output the exposure dose as a graph from the display creation means 903.
Here, FIG. 13 is an example of an exposure dose management screen 130 that displays the exposure dose information in a graph. In the exposure dose management screen 130 shown in FIG. 13, the exposure dose of the worker 7 is displayed in the year unit indicated by reference numeral 131, the month unit indicated by reference numeral 132, and the day unit indicated by reference numeral 133. Furthermore, it is also possible to display in various time units such as quarterly units, hour units, and minute units.
The exposure dose management screen 130 uses information on the exposure dose of the worker 7 accumulated in the exposure dose information DB 913, and the daily exposure dose is the sum of the exposure doses per hour, and the exposure dose per year or month. Is calculated by summing the daily exposure dose. Other than this, quarterly exposure doses are calculated in the same way.
In the graphs indicated by reference numerals 131, 132, and 133, the broken line indicates the limit of the exposure dose obtained by multiplying the limit exposure dose in each work unit by the safety factor.

When the exposure dose of the worker 7 reaches the value indicated by the broken line in each graph of the exposure dose management screen 130, the exposure dose management means 912 of the database server 9 ′ It is also possible to notify the operator 7 that the exposure dose has exceeded the specified value by transmitting information indicating a withdrawal instruction or information for outputting an alarm sound.
The exposure dose management screen 130 can also be displayed on the information display unit 31 of the portable information terminal 3 of the operator 7 from the communication means 905 of the database server 9 ′. The operator 7 can confirm the history of his / her exposure dose at the work site 8 by referring to the exposure dose management screen 130.

  Furthermore, the exposure dose management screen 130 can be transmitted from the communication means 905 of the database server 9 ′ to the specialist 17, for example, an industrial physician via the Internet 20. It can be used as a material for statutory health checkups, and appropriate medical advice can be sent to the worker 7.

  The timing at which the history information of the exposure dose is transmitted from the information portable terminal 3 carried by the operator 7 to the database server 9 ′ of the office 12 is determined by the information portable terminal 3 from the dose management apparatus 110. It is also conceivable that the worker 7 transmits the information from the portable information terminal 3 when leaving the radiation control area after the work is completed. At this time, information in the work memory 113 is stored for each worker 7 in the exposure dose information DB 913 of the database server 9 ′ via the Internet 20, and when uploading of information from the database is confirmed, the database server 9 ′. Therefore, a signal for erasing information stored in the work memory 113 may be transmitted. This signal is transmitted to the exposure dose management apparatus 110 via the Internet 20 and the portable information terminal 3, whereby the control circuit 115 of the exposure dose management apparatus 110 deletes all the exposure dose information in the work memory 113. A configuration is also possible.

(Worker scheduling function)
Furthermore, the database server 9 ′ installed in the office 12 can also execute scheduling based on the exposure dose for a plurality of workers 7.
For example, the slope of each graph of the dose management screen 130 shown in FIG. 13 is calculated using the dose information of each worker 7 stored in the dose information DB 913 of the database server 9 ′. Thus, it is possible to calculate the predicted change rate of the exposure dose of the worker 7, predict the work limit time, and place another worker at another place on the work site 8.
As a result, the work manager of the office 12 selects an appropriate worker based on the exposure dose, work skill, work importance, and urgency of the worker 7 by combining known scheduling software and the like. Therefore, it is possible to take over work without reducing workability as much as possible.

(Radiation distribution map creation function)
Furthermore, in the work management system of the present embodiment, a position confirmation means such as a GPS (Global Positioning System) that can confirm the current position of the worker 7 is connected to the portable information terminal 3 carried by the worker 7. Therefore, the dose management means 912 of the database server 9 ′ associates the information on the dose in minutes measured by the dose management apparatus 110 with the position information measured by GPS, so that the radiation management area 912 It is also possible to calculate the radiation dose distribution.
Further, the information on the radiation dose distribution is output to the information display 10 as a display screen visualizing the radiation dose distribution by superimposing the information on the radiation dose distribution on the map information of the radiation management area stored in the plant specification DB 911 in the display creation means 903. can do.
By referring to the visualized radiation dose distribution display screen (not shown), the work manager of the office 12 does not approach the place where the radiation dose measured by passing the operator 7 is high again. It is possible to prompt the operator 7 as described above. Furthermore, by transmitting this radiation dose distribution display screen to the portable information terminal 3 of the worker 7, the worker 7 can continue working safely while paying attention to the area where the radiation dose is large.
