## Abstract

An item management system using tag information includes a wireless tag provided to each of a plurality of products; first to nth (n is a natural number equal to or greater than 2) readers provided at different locations to receive tag information from the wireless tag; and a control module configured to control the first to nth readers, wherein the control module includes a receiving unit configured to receive the tag information; an information generating unit configured to generate the received tag information and response frequency information representing receipt of the tag information for each of the first to nth readers; and a location information generating unit configured to generate location information of the wireless tag by using the response frequency information and the location information of the first to nth readers.

## Claims

### Claim 1

A product management system using tag information, comprising:
a wireless tag provided to each of a plurality of products;
first to nth readers provided at different locations to receive tag information from the wireless tag, where n is a natural number equal to or greater than 2; and
a control module configured to control the first to nth readers, the control module comprising:
a receiving unit configured to receive the tag information;
an information generating unit configured to generate the received tag information and response frequency information representing receipt of the tag information for each of the first to nth readers;
a location information generating unit configured to generate location information of the wireless tag by using the response frequency information and the location information of the first to nth readers, the location information generating unit generating the location information of the corresponding wireless tag by proportionally applying a difference in response frequency of the corresponding tag information received from the readers to a separation distance between the two or more readers receiving the same tag information;
a route generating unit configured to generate route data of the wireless tag when the location information of the wireless tag is changed;
an image storing unit configured to receive and store image data from a plurality of imaging means that photograph images of regions of the first to nth readers;
an object route generating unit configured to sense an object by analyzing the received image data and generate route data of the sensed object by matching coordinate information in the image data of the object with actual physical location coordinate information; and
an integrated information unit configured to store integrated information in which the information about the wireless tag and the information of the object matched with each other are associated, when the route data of the wireless tag and the route data of the object are matched over reference similarity.

### Claim 2 (depends on 1)

The product management system using tag information according to claim 1, wherein the reader includes a specification varying unit for variably adjusting a transmission cycle in which the wireless tag transmits the tag information, and
the control module further includes a communication control unit for controlling the specification varying unit to shorten the transmission cycle when the response frequency information is lower than a reference frequency or when the difference in the response frequency information of the readers receiving the same tag information is lower than a reference difference.

### Claim 3 (depends on 1)

The product management system using tag information according to claim 1, wherein the control module includes:
a tracking image extracting unit configured to extract tracking image data, which is image data of a time zone in which a location change occurs, from the image data of a region where the location change occurs when the location information of the wireless tag is changed; and
a data processing unit configured to store the extracted tracking image data in association with the information of the wireless tag whose location information is changed.

### Claim 4 (depends on 3)

The product management system using tag information according to claim 3, wherein the control module further includes a DB unit in which transfer-planned product information is stored; and
the tracking image extracting unit extracts the tracking image data only when the wireless tag whose location information is changed does not correspond to the transfer-planned product information.

### Claim 5 (depends on 1)

The product management system using tag information according to claim 1, wherein the integrated information unit matches the sensed object with stored photograph or feature point information to extract identity information of the sensed object and stores the extracted identity information to be included in the integrated information.
