Description

Multiple Code Analysis Apparatus Using EPC Header and Method of Performing the Apparatus {METHOD AND APPARATUS FOR DECODING VARIOUS CODES USING EPC HEADER}

The present invention relates to a multiple code analysis apparatus using an EPC header and a method of performing the apparatus, and receives code interpretation information on code information read from a storage medium from a code information server and converts the code interpretation information based on the code interpretation information. And a method for performing the apparatus, wherein the product information corresponding to the EPC header is received from a content server by using the information of the URN or FQDN format.

In the modern industrial society of mass production and mass consumption, numerous products produced by manufacturers in various fields are undergoing a complicated distribution process of sellers and purchased by the general consumer. Accordingly, various technologies have been developed for the effective management of goods in the production process and distribution process.

As an example, techniques for identifying a product by attaching a storage medium storing the product information to the product and reading the product information stored in the storage medium are used. In particular, as a storage medium, RFID, a next-generation recognition technology, is widely used for managing information of various objects such as animals, goods, and objects through IC chip and wireless communication. RFID is a technology that embeds information of the entire process from product production, sales, and purchase to a microchip (IC chip) and tracks it using radio frequency. It is a "electronic tag" or "smart tag", " It is called various names such as "electronic label" and "wireless identification".

1 shows an example of a data area stored in a conventional storage medium.

As shown in FIG. 1, the storage medium 100 may include an EPC header 110 and code information 120.

The EPC header 110 is header information of an electronic product code and indicates what kind of code is recorded on the storage medium. The code information 120 is a unique number assigned to a product, and may include a company code, a product code, a serial number, and the like.

Whereas previous standard codes (e.g., EAN standard codes) are limited to the identification of item units, EPC has the advantage of distinguishing individual products of the same item. That is, the previous EAN can only identify items called "250 ml coke cans", while the EPC can identify even "of any 250 ml coke cans" with the added serial digits. The user reads the EPC using a reader, and inquires in a separate system of detailed product information about the EPC.

The EPC header is standardized with the code information when recording the code information on the storage medium by EPC global.

2 shows a network configuration diagram for inquiring product information corresponding to an EPC in the related art.

Referring to FIG. 2, the reader 202 reads an EPC header and code information recorded in the storage medium 201, converts the read code information into a URN or FQDN, and performs a domain name system (DNS) server. Send to 203. The reader 202 receives the position information of the product corresponding to the code information, that is, the position information of the content server storing and managing the product information from the DNS server 203 and corresponds to the code information from the content server 204. Receive product information.

However, in the network structure for inquiring product information corresponding to the conventional EPC, the product information corresponding to the code information can only be converted if the code information read from the storage medium 201 can be converted into a URN or FQDN. There is a problem that can be received from the server. In addition, there is a limitation that the range of code information that can be used to receive the product information is extremely limited. In other words, the conventional system has a problem that only the code identified by the specific EPC header can be processed.

The multiple code interpretation device using the EPC header and the method for performing the device according to the present invention, when the code information read from the storage medium is code information that can not be converted into the form of URN or FQDN, that is, conventional standardized code We propose a new technique that can interpret new code information other than information.
