The RFID reading device 802 transmits an activation signal from the cable 3 to the RFID 28, receives a response signal returned from each RFID 28 in response to the transmission of the activation signal via the cable 3, and outputs it to the ID detection device 804. do.

Note that when the cable 3 is an unshielded metallic cable, the RFID reader 802 transmits the activation signal and receives the response signal via the cable 3 itself. When the cable 3 is a shielded metallic cable or a coaxial cable, the RFID reader 802 transmits the activation signal and receives the response signal via the shield portion included in the cable 3. Furthermore, when the cable 3 is an optical cable, the RFID reading device 802 transmits an activation signal and receives a response signal via a metal tension cable attached to the optical cable for installation.

In addition, in order to detect the wireless IDs from all RFIDs 28 for one cable 3, the detection control device 800 performs control for detecting wireless IDs in advance until the wireless ID of a new RFID 28 is not detected. Repeat at set time intervals. When the detection control device 800 determines that no new wireless ID of the RFID 28 is detected for one cable 3, it controls the ID detection device 804 to send all of the detected wireless IDs of the RFID 28 to the route detection device 806. Output to .

The wireless DB 600 and the tray DB 602 output wireless information and tray information to the route detection device 806 every time the wiring route of the cable 3 is detected. The design DB 606 outputs design information to the route display device 810.

The route detection device 806 detects the power generation plant 1 and the wiring equipment 2 of this cable 3 based on the wireless information and tray information corresponding to the wireless IDs of all the RFIDs 28 for one cable 3 inputted from the ID detection device 804. The route is detected and output to the route display device 810. In other words, the route detection device 806 detects the position information of the trays 26-ij corresponding to the wireless IDs included in the wireless information about all the cables 3 inputted from the ID detection device 804, with the subscript i being Sort consecutively. The route detection device 806 extracts a set of position information indicating continuous positions obtained as a result of this sorting from the tray information, and detects it as wiring route information of the cable 3 in the power generation plant 1 and the wiring equipment 2.

FIG. 18 is a diagram illustrating an image showing the wiring route of a certain cable 3 detected in the power generation plant 1 shown in FIG. 1. Note that FIG. 18 shows a case where the cable 3 is laid from the third floor of the data center to the fourth floor of the control building. The route display device 810 displays the wiring route information of the cable 3 inputted from the route detection device 806 on the output device 414 in an image that is easy for the user to understand, as shown by the thick line in FIG.

Furthermore, each time a new or additional cable 3 is laid, the user connects the RFID reader 802 of the route detection device 8 to the cable 3 or its metal part, and uses the input device 410 of the maintenance server 4 to detect the wiring route. Perform operations for. Further, if necessary, an operation for detecting the wiring route is also performed for the cable 3 that has been laid but whose route has not been confirmed.

When the user performs this operation, the detection control device 800 controls the RFID reading device 802 to transmit an activation signal to the RFID 28 provided on the tray 26. When the RFID 28 receives the activation signal from the RFID reader 802 via the cable 3, it transmits a response signal. That is, only the RFID 28 attached to the route where the cable 3 is actually laid is activated and transmits a response signal. RFID reading device 802 receives a response signal from RFID 28 via cable 3 and outputs it to ID detection device 804 . The ID detection device 804 detects the wireless ID of each RFID 28 from the received signal input from the RFID reader 802, stores it in the RAM 406 (FIG. 6) of the maintenance server 4, and further outputs it to the detection control device 800.

The detection control device 800 controls the RFID reading device 802 and the ID detection device 804 to detect the wireless ID of the RFID 28 until the ID detection device 804 no longer detects the new wireless ID of the RFID 28 . When the ID detection device 804 no longer detects the wireless ID of a new RFID 28, the detection control device 800 controls the ID detection device 804 to output the wireless IDs of all detected RFIDs 28 to the route detection device 806.

The route detection device 806 processes the position information indicating the position of the tray 26 in the wiring equipment 2 corresponding to all the wireless IDs input from the position DB 808, and obtains wiring route information of the cable 3 in the power generation plant 1 and the wiring equipment 2. is generated and output to the route display device 810.

The image is displayed on output device 414 for presentation to the user. In addition, the route display device 810 compares the planned wiring route information of the cable 3 inputted from the design DB 606 and the wiring route information inputted from the route detection device 806, and in the wiring equipment 2, the wiring route information is Detect locations where discrepancies occur.

Furthermore, the route display device 810 displays the position where a mismatch occurs in the wiring route information superimposed on the image showing the wiring route. Further, the route display device outputs mismatch information indicating a position where a mismatch occurs in the wiring route information to the inspection device 526 of the construction/maintenance device 5.

When the user performs an operation on the input device 410 to specify the mismatched position displayed on the output device 414, the route display device 810 displays the wireless ID of the cable 3 corresponding to the specified mismatched position and the cable 3. Mismatch information indicating which tray 26 is installed is generated. Further, the route display device 810 displays the generated mismatch information in association with the designated mismatch position in the image showing the wiring route.

If the wiring route detection method described here is carried out each time a new or additional cable 3 is added to the wiring equipment 2, the wiring route of each cable 3 in the power generation plant 1 and its The location of the discrepancy with the plan before installation and information on the discrepancy can be obtained. Each time the detection of the wiring route of the cable 3 is completed, or after the detection of the wiring route of all the cables 3 is completed, the cable 3 for which there is a discrepancy in the wiring route and its pre-laying plan shall be inspected by the installer. The wiring will be renovated to follow the planned wiring route.

FIG. 19 is a diagram showing maintenance of materials over the entire life cycle from laying the wiring of the cable 3 to replacement by the maintenance server 4 shown in FIG. 7 etc., which is performed in the power generation plant 1 shown in FIG. 1 etc. It is. As shown in FIG. 19, the construction planning device 520 (FIG. 7) designs the laying of the cable 3 according to the user's operation, generates planning information (FIG. 11), and designs the DB device 6. It is stored in the DB 606 (FIG. 8). In step S200, the construction information generation device 522 further processes the generated plan information according to the user's operation, generates construction information (FIG. 12), and stores it in the construction DB 608.

The user inputs the cable ID of this cable 3 and the result of the construction into the input device 410 every time construction for laying one cable 3 is performed in the power generation plant 1 according to the construction information. In step S202, the construction management device 524 associates the cable ID input to the input device 410 with construction result information indicating the result of the construction, generates result information (FIG. 13), and performs the construction of the DB device 6. The result is stored in the DB 610. This result information is used by the user to confirm the result of construction for laying the cable 3.

In step S204, the inspection device 526 inspects the cable 3 using the sensor 14 (FIG. 1), associates the inspection result with the discrepancy information obtained through the processing of the route detection device 8, and sets the inspection information ( FIG. 14) is generated and stored in the test result DB 612 of the DB device 6. This test result information is used by the user to confirm the status of each cable 3.

In step S206, the deterioration diagnosis device 528 estimates the deterioration state of the power generation plant 13 using the sensor 14, generates deterioration information (FIG. 15), and stores it in the deterioration DB 614 of the DB device 6. This deterioration information is required by the user to confirm the state of deterioration of each cable 3, and is also used by the material search device 506 to generate material information (FIG. 10). The material information generated by the material search device 506 is stored in the material DB 604 of the DB device 6.

In step S208, when the user refers to the deterioration information and determines that one of the cables 3 has deteriorated, the user searches the material DB 604, selects a new cable 3 to replace the deteriorated cable 3, Replace the deteriorated cable 3 with a new cable 3. Note that the selection of a new cable 3 to replace the deteriorated cable 3 may be automatically performed by the material search device 506. In this case as well, it is preferable that the installation route for the new cable 3 be created (selected) based on the class of the cable 3 and the environmental information on the wiring equipment.

As explained above, the maintenance server 4 (see FIG. 6, etc.) is responsible for designing, constructing, and checking the results of laying the cables 3 in the power generation plant 1, performing post-laying inspections, predicting deterioration, and detecting deteriorated cables 3. Can assist in selecting alternatives. Therefore, the maintenance server 4 can not only support the construction of the cable 3 but also support the maintenance of materials such as the cable 3 over the entire life cycle of the power generation plant 1.

Note that the number of cables 3 arranged on the bottom surface of the tray 26 is, for example, about 10 to about 200 to 300. In FIG. 4, each tray 26 has seven RFIDs 28, and in FIG. 17, each tray 26 has six RFIDs 28, but the number of RFIDs 28 in one tray 26 is arbitrary. be. Furthermore, each tray 26 may be covered with a lid that can prevent the activation signal and the response signal from leaking to other trays 26. Specific numerical values such as the reach distance, frequency, and transmission timing of the response signal shown in the embodiment are merely examples, and may be changed as appropriate depending on the configurations of the power generation plant 1 and the route detection device 8.

Moreover, although the embodiment using RFID28 as an example of a radio|wireless identification device was described, the radio|wireless identification device of this invention is not limited to RFID28. For example, as a radio identification device, it is also possible to use a device that can transmit and receive at a frequency other than the standardized frequency band for RFID (for example, a low frequency band around 5 kHz). Further, the wireless identification device only needs to be installed at a location suitable for transmitting and receiving signals between the wiring (cable), and may be installed on the wiring equipment 2 itself or on a place other than the wiring equipment 2. In addition, although confirmation of the condition and deterioration state of the cable 3 generated by the inspection device 526 and the deterioration diagnosis device 528 has been explained, the confirmation data generated from these can be used to confirm the activation of each cable route when an accident occurs in the power plant 1. The maintenance server 4 may also include a live line monitor that can be used to check the line status.
