Abstract

When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.

Claims

1. An RFID cable system comprising

a cable, a plurality of RFID tags being attached to said cable in a predetermined order;

and

a data storage for storing information stored in said plurality of RFID tags and information of an arrangement order of said plurality of RFID tags attached to said cable, said data storage being arranged at an outside of said cable;

wherein said data storage stores new cable identification name and information stored in RFID tags arranged on a newly manufactured cable or information stored in an RFID tag arranged on a portion near to a cut portion of said RFID cable which has been cut, said data storage stores said new cable identification name, said information stored in RFID tags, and said information of the arrangement order of said plurality of RFID tags.

2. The RFID cable system of claim 1,

wherein each of said RFID tags has an ID, said RFID tags are arranged in a longitudinal direction of said cable;

and

a database for storing a plurality of said IDs of said RFID tags bonded to said cable, and the order of said RFID tags bonded to said cable,

wherein said RFID tags are arranged on a ribbon in accordance with said order, and said ribbon is included in said cable.

3. The RFID cable system according to claim 2, further comprising:

a processing unit for receiving information stored in any one of said RFID tags arranged on said cable, and for searching information stored in said database to obtain a cable identification name.

4. The RFID cable system of claim 1, further comprising:

a display screen; and

a processing unit for receiving a cable identification name of a cable to be removed, and for receiving information stored in any one of said RFID tags arranged on said cable, and for searching information stored in said data storage to obtain a cable identification name, and for displaying a message indicating removal on said display screen when said cable identification name stored in said data storage is said cable identification name of said cable to be removed, and for displaying a message indicating no removal on said display screen when said cable identification name stored in said data storage is not equal to said cable identification name of said cable to be removed.

5. A method for using an RFID cable system comprising the steps of:

attaching a plurality of RFID tags on a cable in a predetermined order; and

storing information sorted in said plurality of RFID tags and information of an arrangement order of said plurality of RFID tags attached to said cable into a data storage arranged at an outside of said cable;

wherein said data storage stores new cable identification name and information stored in RFID tags arranged on a newly manufactured cable or information stored in an RFID tag arranged on a portion near to a cut portion of said RFID cable which has been cut, said data storage stores said new cable identification name, said information stored in RFID tags, and said information of the arrangement order of said plurality of RFID tags.

6. The method for using an RFID cable system of claim 5, further comprising the steps of:

arranging a plurality of RFID tags on a ribbon in a predetermined order;

each of said RFID tag has an ID,

bonding said ribbon to a cable in accordance with said order, said RFID tags are arranged in a longitudinal direction of said cable; and

storing, in a database, information corresponding to each RFID including an ID of each RFID, and the order of said RFID tags bonded to said cable.

7. The method for using an RFID cable system of claim 6, further comprising the steps of:

receiving information stored in any one of said RFID tags arranged on said cable, and

searching information stored in said database to obtain a cable identification name.

8. The method for using an RFID cable system of claim 5, further comprising the steps of:

receiving a cable identification name of a cable to be removed by a processing unit,

receiving information stored in any one of said RFID tags arranged on said cable, by the processing unit,

searching, by the processing unit, information stored in said data storage to obtain a cable identification name; and

displaying a message indicating removal on a display screen when said cable identification name stored in said data storage is said cable identification name of said cable to be removed, and displaying a message indicating no removal on said display screen when said cable identification name stored in said data storage is not equal to said cable identification name of said cable to be removed.
