It is.

When the portable terminal 3 receives such work instruction data, the portable terminal 3 displays the work instruction on a display. The worker at the work site B performs the wiring work of the intra-office communication facility 10 based on the work instruction displayed on the display. This wiring work is performed by reading the identification code 15 assigned to the communication cable 14 and the like by the identification code reader 16 and constantly confirming that the work is correctly progressing. After the work is normally completed, the portable terminal 3 electronically reports the work completion to the management computer 2 via the LAN. In this work completion report, the actually performed wiring configuration is listed as a column of the identification code 15.

The control unit 7 of the management computer 2 manages the work progress, and compares the wiring indicated by the work completion report with the wiring given by the work instruction by the wiring comparing means 8. Then, the comparison result in the wiring comparing means 8 is given to the database updating means 9, and the database updating means 9

As a result, it becomes possible to perform wiring different from the work instruction at the discretion of the worker, and it is possible to perform highly flexible and highly efficient wiring work.

Here, the case where the work different from the work instruction is performed is as follows: (1) In the work of laying the communication cable 14, the shape of the laid floor is peculiar (database such as existence of temporarily placed articles on the laying route). 6 is a factor that cannot be fully understood), and it is difficult to lay the work according to the work instruction. (2) In the wiring work of the communication line 14b, the length of the communication line 14b may be insufficient or congestion may easily occur. . When the laying floor has a unique shape, the laying work bypassing the communication cable 14 is performed by an operator. In the case where the length of the communication line 14b is insufficient, for example, the line connection substituted by another vacant communication line 14b or the line connection substituted by the empty port 21 of the intermediate module 20 is performed by the operator. .

As an example of the line connection substituted by another vacant communication line 14b, as shown in FIG. 7, the work instruction instructs the connection of {(p1, a1), (p2, b1)}. What you are doing, by the judgment of the site ｛(p1, a
2), there is an example in which the connection is changed to the combination of (p2, b2)}. Further, as an example of the line connection substituted by the empty port 21 of the intermediate module 20, as shown in FIG. 8, the work instruction instructing the connection of (p2, a1) is changed to (p16 , A1) in some cases.

Then, it is determined whether or not there is a problem in the data transmission. For example, when the transmission module 18 is mounted on the transmission frame 17 other than the specified one, whether or not this mounting location is reserved (1) Whether another work order has already been issued to the mounting location), (2) whether a failure report has been received before,
(3) Whether the transmission module 18 is allowed to be mounted, (4)
Confirm that the existing service can be implemented.

As another example of determining whether or not there is a problem in data transmission, when a line connection is made by using the free line 14b or the free port 21, the first work instruction is as shown in FIG. A check is performed to determine which port 19 of which transmission module 18 is connected to which port 23 of which termination module 22. next,
Based on the work completion report made by the worker, (b) it is checked which port 19 of which transmission module 18 is connected to which port 23 of which end module 22. When (a) and (b) match, the data introduced into the transmission module (starting point of the wiring) 18 is transferred to a predetermined port (exact position) 23 of the terminating module (end of the wiring) 22. It is determined that there is no problem in data transmission as it can be reached. (A) and
If (b) does not match, it is determined that there is a problem in data transmission.

If it is determined that there is no problem in data transmission, the contents of the work completion report are stored in the database 6.
Register with. When it is determined that there is a problem in data transmission, a new work instruction is issued to the worker to perform the work again.

The present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention.

[0029]
