Abstract

The present invention relates to a method of location management on the road using RFID series. In particular, the present invention provides RFID series, where a number of RFID tags are concurrently installed without the need of installing RFID tags one by one and ID of each RFID tag is automatically computed, and therefore work can be completed with a little time and workforce without confusion even where a number of RFID tags are required in order to constitute an RFID system, and a method of location management on the road to specifically grasp the location where an optional thing on the road (e.g. a car) stops or moves using the RFID series.

Claims

1. In RFID series encapsulated in the shape of string after wrapping a number of RFID tags with a covering, where the RFID tags are continuously arranged at regularly spaced intervals (d) and a division or a color indicating connection intervals (d) between the RFID tags is coded on the covering, a method of location management on the road, wherein the location connecting optional two points (a, b) on the road is managed, comprising:

(a) hollowing out serial grooves between the optional two points (a, b) and bury RFID series;

(h) reading and recording IDs of the head (a) and the end (b) of the buried RFID series by use of an RFID reader;

(c) monitoring and inputting the arrangement order of RFID tags in the database;

(d) reading an RFID tag at an optional point (objective RFID tag) by use of an RFID reader; and

(e) monitoring that the objective RFID tag is an RFID tag located on n^th from the RFID tag located on the head (a) and confirming that the objective RFID tag is located at L from the head (a) where L is resulted from multiplying n and d.

2. The method of claim 1, further comprising monitoring and input IDs of RFID tags in the database and to assign IDs of the RFID tags and their corresponding zone IDs and match them after step (c).

3. The method of claim 2, wherein the zone IDs comprises information on the name of area where RFID tags of RFID series installed on the road according to an administrative district or the distance of the concerned RFID tags from the head RFID tag of RFID series installed on the road.
