Description

  Embodiments described herein relate generally to a cable management method, a cable management system, and a cable management apparatus.

  Currently, in power facilities such as power plants, cables wound around drums are pulled out and cut by the installation length of the construction site, and are divided into multiple cable trays and conduits arranged according to the type of electrical circuit. Work is being laid on the applicable items.

  Usually, a cable tray or a conduit has a code or the like for identifying an electric circuit on its side surface, and the operator visually recognizes the code and lays the corresponding cable.

  By the way, when laying the cable on the cable tray in a case where the cable source is long and the source of the cable is not visible, the cable path can be identified by the notation of the cable tray, but there is no sign of the cable on the cable. However, since the cable is limited to the end of the cable, it is necessary to trace the cable and confirm the origin of the cable, and then install the cable on the cable tray of the corresponding type of electric circuit.

  Also, cable trays that already have cables laid out have many cables laid on one tray, which often extends to multiple levels, so when replacing or reconnecting cables during maintenance work Therefore, it is necessary to check the electric circuit (connection source, wiring flow, relay unit, connection destination, etc.) with great care to avoid wiring mistakes.

Furthermore, in addition to the horizontal and vertical directions of the feed mechanism 56, a drive roller (not shown) that rotates the shaft of the cable 8 is provided, so that codes (characters) can be printed spirally on the cable 8. .

  The notebook PC 4 includes an issuing unit 40, a storage unit 41, a USB port 42 as an external memory reader, a control unit 43, an input unit 44 such as a keyboard, and a display unit 45 such as a monitor.

  The USB port 42 is connected to a storage medium such as the USB memory 18 to exchange information about the cable 8. The USB port 42 reads the information of the cable 8 from the USB memory 18 in which the information of the cable 8 is stored in, for example, the notebook PC 17.

  The issuing unit 40 acquires the laying instruction information of the cable work instruction form 20 read by the code reader 3 and the information (drum number) of the drum 6, reads the information of the cable 8 stored in the USB memory 18, and this information A new cable ID that does not match the issued cable ID (existing ID) included in the ID is issued, and the information of the cable 8 obtained from the USB memory 18 and the information of the cable 8 that has been keyed in the issued cable ID. Are registered in the management table 41a of the storage unit 41 in association with each other.

  That is, the issuing unit 40 refers to the information in the USB memory 18 based on the laying instruction information acquired by the code reader 3 and the keyed cutting position, and has already issued the cable ID managed on the server 10 side. A newly generated cable ID is issued so as not to overlap (identification information unique to the cable), and the issued cable ID, tray number, drum number, and cutting position are associated with each other and stored in the storage unit 41.

  The storage unit 41 stores a management table 41a (see FIG. 5) as a management information storage unit and a print information table 41b (see FIG. 6) as a print information storage unit.

  As shown in FIG. 5, the management table 41a stores the issued cable ID in correspondence with the tray number, the drum number, and the cutting position.

  The cable ID is identification information for identifying the individual of the cut cable 8, and is an ID issued each time. The tray number is identification information of the cable tray obtained from the server 10 by the inquiry request. Cable trays are arranged separately for each type of electrical circuit. The type is, for example, regular or emergency. The drum number is information obtained from the barcode 24 on the label 61 of the drum 6.

  The From point at the cutting position is the initial length of the cable 8 before being wound around the drum 6, and the To point indicates the length at which the cable 8 is drawn from the drum 6 and cut. For example, if the From point is 900 m and the To point is 750 m, the length of the cable 8 for each application created by cutting is 150 m of the difference.

  As shown in FIG. 6, the print information table 41b stores an electric circuit color, a line color, and a print target in association with each tray number as the electric circuit type. In addition to the tray number, the electric path type may be a conduit ID. The electric circuit color is information for designating the color of information printed on the cable 8.

  The print target indicates information to be printed. In the example of FIG. 6, when the electric circuit type is “AAA1”, the electric circuit type and the cable ID are to be printed, and “AAA1” from the management table 41 a of FIG. 5. And a code (character) of “XXXX-001” is printed.

  The line color is information for designating the color of the line when printing information other than the electric circuit type and the cable ID on the cable 8, for example, a line.

  In the example of the print information table 41b in FIG. 6, when the electric circuit type is the code “AAA2,” the line is also printed in addition to the tray number and the cable ID, and “AAA1”, “XXXX-002”, “colored” Line "is printed.

  For “colored lines”, the line width and line length are set to fixed values. The information to be printed is set in advance in the storage area outside the table or in the control unit 43 in the case of a fixed value that is not changed only by the electric circuit type and cable ID.

  In this example, the electric circuit color and the line color are the same color, but they may be set differently. In addition, character type, line width, length, interval, and the like may be set as print information. In the default setting, for example, it is assumed that characters and lines are 3 m intervals, and lines are continuous.

  The control unit 43 specifies a print target (in this example, an electric circuit type and a cable ID) and a color (green) according to the tray number (electric circuit type) from the print information table 41b based on the installation instruction information, and the management table 41a. Information to be printed (“AAA1” and “XXXX-001”) is read out from the printer, and the information to be printed (“AAA1” and “XXXX-001”) is printed on the cable 8 in color (green). .

Subsequently, a procedure for cable laying work in which the cable management system of this embodiment is introduced will be described.
When laying a new cable 8 on a cable tray at a cable laying location, the long cable 8 wound around the drum 6 is cut to generate a cable 8 for each application.

  In this case, the notebook PC 17 in the office creates the cable 8 installation instruction information, and outputs the print data of the barcode 24 in which the instruction information is encoded to the printer 16, so that the cable work instruction form 20 is installed. A barcode 24 is printed together with the instruction information.

  The operator brings the cable work instruction form 20 with the barcode 24 and the USB memory 18 created in the office to the building where the drum 6 as the cable cutting work place is placed, and creates the cable 8 for each use. Work to do.

When creating the cable 8 for each application, first, the USB memory 18 is connected to the notebook PC 4 and information regarding the cable of the USB memory 18 is captured.
Subsequently, the bar code 24 of the cable work instruction form 20 is scanned (scanned) by the code reader 3, and the installation instruction information of the bar code 24 is taken into the notebook PC 4.

  Further, the barcode 24 of the label 61 attached to the drum 6 is scanned by the code reader 3, and the drum number indicated by the barcode 24 is taken into the notebook PC 4.

  In the notebook PC 4, the issuing unit 40 issues a cable ID for each newly generated application based on the acquired installation instruction information and information on the cable taken in from the USB memory 18.

  When issuing the cable ID, the issuing unit 40 reads the issued cable ID included in the cable information fetched from the USB memory 18, and issues a unique ID that does not overlap with the read issued cable ID.

  The issuing unit 40 has the newly issued cable ID, information on the electric circuit for laying the cable 8 included in the acquired laying instruction information, the drum number read from the label 61 of the drum 6, and the keyed cable 8. The length information (from position of cutting position, To) is associated and stored in the management table 41a of the storage unit 41.

  After the cable 8 of the drum 6 is pulled out and set in the color printing mechanism 5, when the printing start operation is performed from the input unit 44, the control unit 43 refers to the printing information table 41b and prints according to the type of the electric circuit. The color and information to be printed (cable ID and electrical path type) are specified, the color printing mechanism 5 is controlled, and the cable ID and electrical path type are printed in the corresponding print color on the cable 8 while the cable 8 is pulled out from the drum 6.

  As shown in FIG. 7, the operator brings the cable 8 (see FIG. 4) for each application, which is generated by printing with the color printing mechanism 5 and cut to a length suitable for the application, to the installation work place. The characters 81 (cable ID and electric circuit type) printed on the cable 8 and the color thereof, and the tray number 71 and the color (electric circuit type color) displayed on the cable tray 9 are confirmed to be visually matched. The cable 8 is laid on the cable tray 9.

  As described above, according to the cable management system of this embodiment, when the cable 8 is created in the field, the cable 8 itself has a combination of the electric circuit type (information indicating the electric circuit) and the cable ID (information indicating the individual cable). By printing the character 81, the installation work can be performed while confirming the electric path and installation location of the cable 8 to be used by being drawn and cut from the drum 6 by a desired length.

  Further, during maintenance work, the maintenance target cable 8 can be easily identified from among the many cables 8 already laid in the electric circuit. Furthermore, by printing in a plurality and spiral, it is possible to prevent the printing from becoming difficult to see depending on the orientation of the cable.

In the present embodiment, the following effects can be obtained.
1. Since the application of the cable 8 can be specified even in the middle of the electric circuit, it can be visually confirmed whether the cable 8 correctly created for each application is installed in the electric circuit.

  2. When maintenance work such as extending the cable 8 is performed, the cable 8 can be laid out by distinguishing the correct electric path.

  3. At the work site where the cable 8 is actually laid, codes (characters) such as an electric circuit type and a cable ID are printed on the cable 8 that has been cut according to the application, so the printing position of the cable 8 can be adjusted when printing, By printing on the surface in a spiral shape, it is possible to print on a portion that is easy to visually recognize after laying the cable 8 and to improve the visibility of the print information of the cable 8.

  4). Since each cable 8 is assigned (printed) with a unique ID, it is possible to manage the individual cables 8 even after the cables have been installed, check the history of the installation work, maintain the cables 8, and Workability such as usage status confirmation can be improved. Further, since this cable ID printing is also used to associate with the type color of the electric circuit, useful information such as the cable ID can be used as the correspondence identification information with the electric circuit.

  Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  In the above embodiment, the cable tray 9 is illustrated as an example of the electric circuit, and the example in which the cable 8 is laid on the cable tray 9 has been described. However, for example, as illustrated in FIG. In some cases, a pull box 73 is used as a relay box for relaying.

  Even when laying the cable 8 in the pull box 73, the operator works while confirming the match between the conduit ID 74 displayed on the conduit 72 and the code (character) printed on the cable 8. Therefore, this case is also effective.

  The constituent elements of the server 10 and the notebook PC 4 shown in the above embodiment may be realized by a program installed in a storage such as a hard disk device of a computer. The above program may be realized by a computer-readable electronic medium: electronic media.
