Description

  The present invention relates to a cable having information recording means for a cable and a cable management system for managing the cable.

  When connecting cables between devices that are separated from each other, cut the required length from a long cable wound on a reel, etc. according to each connection destination, and then send information such as the cable length and connection destination to the cable. When connecting the cable to the device, check the mark.

FIG. 4 is a diagram showing a configuration example of a conventional cable.
In FIG. 4, markings 2 a, 2 b, 2 c are marked with characters, symbols, colors, etc. at the ends of the cables 1 a, 1 b, 1 c so that the cables are not mixed when laid.

By arranging recording means that records information about cables on the surface of insulators, protective coatings, etc., or inside them, cables that can check information about cables from the outside not only at terminals but also at intermediate parts As shown, for example, there was one described in Patent Document 1.
JP 2003-203527 A

However, the conventional example has the following problems.
When many cables are cut out from a long cable wound on a reel or the like, it is not easy to measure the length of the necessary cable. In addition, in order to manage cables that have been cut and select necessary cables from the cables, there is a problem in that the markings attached to the cables must be confirmed one by one.

  The present invention has been made to solve the above-described problems, and an object thereof is to realize a cable that can easily check the position information of the cable and a cable management system that manages the cable.

In order to achieve such a subject, the present invention is configured as follows.
(1) In a cable having an IC tag,
A plurality of the IC tags are arranged in the length direction of the cable, and have a cable ID code and position information corresponding to the position of the IC tag.

(2) The cable according to (1), wherein the IC tags are arranged at equal intervals.

(3) In the cable management system for managing the cable described in (1) or (2),
When cutting the cable, a cable cutter that reads the ID code and the position information from an IC tag near the cutting portion;
A database holding information of the cable cutter;
A cable management system comprising:

(4) In the cable management system for managing the cable described in (1) or (2),
The cable management system according to (3), further comprising a display device that reads the IC tag and displays the cable information with reference to the database.

The present invention has the following effects.
An appropriate cable cutting position can be easily determined from the position information of the IC tag.
Further, cables can be managed based on the ID code and position information of the IC tag, and necessary cables can be easily selected.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a cable according to the present invention.
In FIG. 1, IC tags 10 are arranged at equal intervals on the cable 1. Each IC tag 10 is recorded with an ID code and position information. The ID code is a number assigned to each long cable wound on a reel or the like such as a production number. The position information is length information corresponding to the position of the IC tag.

In this figure, the IC tags 10 are arranged on the cable 1 at equal intervals of 1 m. For example, the IC tag 10-1 has “CBL1” as ID code and “1m” as position information recorded therein. In the tag 10-200, “CBL1” is recorded as an ID code, and “200m” is recorded as position information. The arrangement of the IC tag 10 may be on the surface of the cable 1 or inside.
In addition, cable information such as manufacturer, date of manufacture, cable product name, standard, etc. can be recorded in the IC tag 10.

There is a 1000m long cable. The position information of the IC tags 10-1 and 10-1000 at both ends of the cable 1 is “1 m” and “1000 m”.
The position information of the IC tag 10-200 indicates “200m”, and the position information of the IC tag 10-201 indicates “201m”. In this case, the position of the IC tag is arranged so that the cable length becomes 200 m when the predetermined CUT position 20a between the IC tags 10-200 and 10-201 is cut.
Similarly, the position information of the IC tag 10-400 indicates “400 m”, and the position information of the IC tag 10-401 indicates “401”. In this case, the position of the IC tag is arranged so that the cable length becomes 400 m when the predetermined CUT position 20b between the IC tags 10-400 and 10-401 is cut.

FIG. 2 is a diagram showing an embodiment of a cable management system according to the present invention.
In FIG. 2, the cable cutter 30 also serves as an IC tag information reader. When the cable 1 is cut at the CUT position 20a, the ID codes are read from the IC tags 10-200 and 10-201 on both sides of the cut portion. And read location information.
In this figure, the cable cutter 30 is a manual one, but may be an automatic one.
Information read by the cable cutter 30 is transmitted to the database 40 and stored.

By using the data stored in the database 40, the length of the cut cable can be known.
For example, in the cable 1 of FIG. 1, when the cable cutter 30 is cut at the cutting position 20a, the cable cutter 30 has the ID code and position information of “CBL1-200m” from the IC tag 10-200 and “CBL1-201m” from the IC tag 10-201. And store these information in the database 40. Next, when cutting at the cutting position 20b, the cable cutter 30 reads the ID code “CBL1-400m” from the IC tag 10-400 and “CBL1-401m” and the position information from the IC tag 10-401, and these information. Is stored in the database 40.

  By performing the association using the data stored in the database 40, “CBL1-1m” and “CBL1-200m”, “CBL1-201m” and “CBL1-400m”, “CBL1-401m” and “CBL1- It can be recognized that 1000 m "is the both ends of the same cable, and the cable lengths are 200 m, 200 m, and 600 m, respectively.

In addition, even if the cables have the same cable length of 200 m cut out from the same cable 1, the position information of the IC tag is “1 m” and “200 m” for one cable, and “201 m” and “400 m” for the other cable. Therefore, a separate identification code is attached to each cut out cable, and the cables can be selected.
Therefore, it is possible to identify the cable without marking again at both ends of the cable.

FIG. 3 is a diagram showing another embodiment of the cable management system according to the present invention.
In FIG. 3, the display device 50 reads information “CBL1-400m” of the IC tag 10-400 at the end of the cable 11. By referring to the information stored in the database 40, it is understood that the information of the IC tag 10-201 at the other end of the cable 11 is “CBL-201m” and the cable length is 200 m. Can be easily selected.
On the contrary, when the information on the IC tag 10-201 is read by the display device 50, the information on the IC tag 10-400 at the other end of the cable is correlated by referring to the information stored in the database 40. Therefore, it is understood that the cable length is 200 m, and the cables can be selected.

  Further, when the information in the database 40 is used, it can be seen that “CBL1-201m” and “CBL1-400m” are both ends of the same cable and the cable length is 200 m. Even when the information (for example, “CBL-305m”) is read, since it is between “CBL1-201m” and “CBL1-400m”, it can be seen that the cable length is 200 m.

The display device 50 may be one in which the contents of the database 40 have been taken in advance, or one that exchanges data with the database 40 each time.
In addition, if information such as the cable length and connection destination is written to the IC tag after the cable is cut, it is easy to select the necessary cables simply by reading the information on the IC tag with the display device 50 when laying the cable. Can do.

It is a block diagram which shows one Example of the cable which concerns on this invention. It is the figure which showed the Example of the cable management system which concerns on this invention. It is the figure which showed the other Example of the cable management system which concerns on this invention. It is the figure which showed the structural example of the conventional cable.
