When the electric wire 9 is connected to the control terminal block 7 and the main circuit terminal block 8 and the band marks 11 and 12 attached to the electric wire 9 are imaged by the camera 16, the control unit 13 is imaged. The image data is created in association with the serial number, the item number, and the board number, and the image data signal including the created image data is transmitted from the data communication unit 14 to the server 3. Further, when the operator operates the display 15 to instruct data collation, the control unit 13 causes the data communication unit 14 to transmit the collation instruction signal to the server 3.

The design data acquisition unit 19a acquires design data based on a wiring connection diagram showing the connection of the electric wire 9 to the terminal block of the switchboard. That is, for example, when a wiring connection diagram is created by a computer design support tool (CAD) in a PC terminal 24, design data is created from the created wiring connection diagram, and a design data signal including the created design data is generated. Since it is transmitted from the PC terminal 24, the design data acquisition unit 19a acquires the design data by receiving the design data signal transmitted from the PC terminal 24. Since the wiring connection diagram contains information on the serial number, item number, drawing number, board number, terminal block device number, terminal block number, color matching, cursor, extension terminal number, and external line terminal number. , The information is also included in the design data created from the wiring connection diagram.

The phase color is the color of the electric wire 9. The extension terminal number is the number of the extension terminal to which the electric wire 9 is connected. The terminal number of the external line is the number of the external line terminal to which the electric wire 9 is connected. When the design data acquisition unit 19a acquires the design data, the design data acquisition unit 19a stores the acquired design data in a database in the design data storage unit 21.

When the image data signal transmitted from the mobile terminal 2 is received by the data communication unit 20, the image data acquisition unit 19b extracts and acquires image data from the received image data signal, and the acquired image data. Is stored in the image data storage unit 22 as a database.

The recognition data creation unit 19c reads the image data from the image data storage unit 22, analyzes the read image data, and creates the recognition data. That is, the recognition data creation unit 19c is a case where the band marks 11 and 12 of the electric wire 9 connected to the control terminal block 7 are imaged, and the captured image data includes the terminal block device number, the terminal block number, and the like. If the cursor, internal line terminal number, and external line terminal number are included, the image data is analyzed to create recognition data including the terminal block device number, terminal block number, cursor, internal line terminal number, and external line terminal number. .. The recognition data creation unit 19c is a case where the band marks 11 and 12 of the electric wire 9 connected to the main circuit terminal block 8 are imaged, and the image data captured is captured by the terminal block device number, color matching, and cursor. , If the extension terminal number is included, the image data is image-analyzed to create recognition data including the terminal block device number, color matching, cursor, and extension terminal number. When the recognition data creation unit 19c creates the recognition data, the recognition data is stored in the recognition data storage unit 23 as a database.

When the collation instruction signal transmitted from the mobile terminal 2 is received by the data communication unit 20, the collation unit 19d designs design data corresponding to the serial number, item number, and board number associated with the image data. It is read from the storage unit 21, the recognition data is read from the recognition data storage unit 23, and the read design data and the recognition data are collated. That is, if the band marks 11 and 12 of the electric wire 9 connected to the control terminal block 7 are imaged, the collation unit 19d may use the terminal block device number, terminal block number, cursor, extension terminal number, and outside line terminal. Match the design data including the number with the recognition data. If the band marks 11 and 12 of the electric wire 9 connected to the main circuit terminal block 8 are imaged, the collation unit 19d includes design data including the terminal block device number, color matching, cursor, and extension terminal number. And the recognition data are collated.

In this case, if the electric wire 9 is correctly connected to the control terminal block 7 and the main circuit terminal block 8, the design data and the recognition data will match. On the other hand, if the electric wire 9 is not correctly connected to the control terminal block 7 and the main circuit terminal block 8, the design data and the recognition data will not match. The collation result output unit 19e causes the data communication unit 20 to transmit a collation result signal including the collation result of the collation unit 19d to the mobile terminal 2.

In the mobile terminal 2, when the collation result signal transmitted from the server 3 is received by the data communication unit 14, the control unit 13 extracts and acquires the collation result from the received collation result signal, and acquires the collation result. The collation result is displayed on the display 15.

Store the number (S2). Next, the control unit 13 operates the display 15 with respect to the control terminal block 7 and the main circuit terminal block 8 in a state where the operator has completed the wiring work of the electric wire 9 to the control terminal block 7 and the main circuit terminal block 8. When it is determined that the band marks 11 and 12 attached to the electric wires 9 connected to the above are imaged by the camera 16 (S3: YES), the captured image data is associated with the serial number, item number, and board number. (S4), and the data communication unit 14 transmits the image data signal including the created image data to the server 3 (S5). Next, when the control unit 13 determines that the operator has operated the display 15 to instruct data collation (S6: YES), the control unit 13 causes the data communication unit 14 to transmit the collation instruction signal to the server 3 (S7).

In the server 3, the control unit 19 determines that the design data signal transmitted from the PC terminal 24 has been received by the data communication unit 20 because the wiring connection diagram is created by the computer design support tool in the PC terminal 24 ( T1: YES), design data is extracted from the received design data signal and acquired (T2), and the acquired design data is stored in a database in the design data storage unit 21 (T3).

Next, when the control unit 19 determines that the image data signal transmitted from the mobile terminal 2 has been received by the data communication unit 20 (T4: YES), the control unit 19 extracts and acquires image data from the received image data signal. (T5), the acquired image data is stored in the image data storage unit 22 as a database (T6). Next, the control unit 19 reads the image data from the image data storage unit 22, analyzes the read image data to create recognition data (T7), and stores the created recognition data in the recognition data storage unit 23. Convert and memorize (T8).

Next, when the control unit 19 determines that the collation instruction signal transmitted from the mobile terminal 2 has been received by the data communication unit 20 (T9: YES), the control unit 19 determines that the serial number, item number, and board number associated with the image data. The design data corresponding to is read from the design data storage unit 21, the recognition data is read from the recognition data storage unit 23, and the read design data and the recognition data are collated (T10). Next, the control unit 19 causes the data communication unit 20 to transmit the collation result signal including the collation result to the mobile terminal 2 (T11).

In the mobile terminal 2, when the control unit 13 determines that the collation result signal transmitted from the server 3 has been received by the data communication unit 20 (S8: YES), the control unit 13 extracts the collation result from the received collation result signal. It is acquired (S9), and the acquired collation result is displayed on the display 15 (S10).

That is, if the design data and the recognition data match and the collation result is positive, the control unit 13 operates the display 15 and inputs the serial number, item number, and panel as shown in FIG. Along with the number, the character "pass" indicating that the collation result is positive is displayed on the display 15. On the other hand, if the design data and the recognition data do not match and the collation result is negative, the control unit 13 operates the display 15 to input the serial number, item number, and so on, as shown in FIG. Along with the board number, the characters "Fail" indicating that the collation result is positive and the inconsistent portion are displayed on the display 15.

Specifically, for example, in the control terminal block 7, if the electric wire 9 to be connected to the extension terminal number "16B" and the electric wire 9 to be connected to the extension terminal number "17B" are mistakenly connected by mistake. Since the corresponding design data and the recognition data do not match, the control unit 13 has the electric wire 9 to be connected to the extension terminal number “16B” and the electric wire 9 to be connected to the extension terminal number “17B” as shown in FIG. Information indicating that is incorrect is displayed on the display 15. Further, for example, if the electric wire 9 to be connected to the extension terminal number "RD1" and the electric wire 9 to be connected to the extension terminal number "TD1" are mistakenly connected in the main circuit terminal block 8, the corresponding design is applicable. Since the data and the recognition data do not match, as shown in FIG. 15, the control unit 13 erroneously connects the electric wire 9 to be connected to the extension terminal number “RD1” and the electric wire 9 to be connected to the extension terminal number “TD1”. Information indicating that the cable is displayed is displayed on the display 15. In this case, the control unit 13 may make it easier for the operator to grasp the error by, for example, blinking the inconsistent portion or displaying the color differently from the others.
