Description

Wireless Internet ordering system and method using RFID tag {WIRELESS INTERNET ORDERING SYSTEM AND METHOD USING RFID TAG}

The present invention relates to an internet order using RFID tags. More particularly, when two or more items need to be purchased, the present invention collectively recognizes each tag for a plurality of items, and then simultaneously through a wireless Internet connection. The present invention relates to a wireless Internet ordering system and method using an RFID tag that can perform an order.

Conventionally, by attaching a barcode to a number of objects, such as various goods, facilities, inventory, etc. to obtain information about the information and price of each object, various application development has been made using this. However, in order to improve the limitations of barcode technology (for example, human intervention for barcode recognition), the use of RFID technology, which is regarded as an alternative to barcodes, is actively taking place, and the future of ubiquitous computing It is considered to be an essential technology to advance.

RFID technology utilizing RFID tags collects and records tag information from RFID tags attached to objects using radio frequency, and uses automated tag recognition and collection (AIDC: Automatic Identification and Data Capturing). It is classified as one of the techniques. The RFID system consists of three main components: a hardware device such as an RFID tag and an RFID reader, and a host computer that receives and processes tag data by connecting to an RFID reader. The RFID reader reads data from the RFID tag and wires the data. It is a method of transmitting to a host computer through a wireless communication network.

In general, in order to utilize RFID technology, RFID tag is assigned a kind of code value to identify the object to which the tag is attached, and the RFID reader periodically collects the code value in the individual tag existing in the RFID reader recognition area. In other words, this task is performed at least ten times per second. The electronic tag information recognized each time is transmitted to the host computer. As code information of an individual RFID tag is transmitted to the host computer several times per second for a plurality of tags existing in the recognition zone, duplicate information is removed from a large amount of electronic tag information, which is to be utilized. There is a demand for a function that purifies and delivers only information necessary for an application.

Accordingly, in recent years, a search system capable of recognizing surrounding object information using RFID technology is being developed. For example, as illustrated in FIG. 1, a system for searching for an information URL in an RFID network environment is disclosed, wherein the above-described Uniform Resource Locator (URL) is a format capable of consistently expressing an address of a resource accessible from the Internet.

In addition, the thing information system refers to a program that provides information on an object with an RFID tag on the Internet. The type of thing information provided by the thing information system may appear in various ways depending on how it is connected to and expressed on the Internet. For example, using HTTP, the World Wide Web protocol, things are supported by HTML pages, image files, web services, Web Service Discription Language (WSDL), programs such as CGI or Java applets, and other HTTPs. It means files.

Meanwhile, as shown, the thing information system group 40 means that one or more thing information systems exist collectively, and the thing information registries 31 to 33 are defined in one or more thing information systems. A type of database that contains registration information about a system. It is a system that performs the function of specifying registration information and finding related information. In general, when specifying a registration information for a system, a program and a service having a common characteristic, and defining a system for discovering related information as a registry, the thing information registry defines a thing information system as a common characteristic. It's a management system.

Accordingly, the type of thing information registry includes a name resolution service 31, an XML registry service 32, and a directory service 33. The thing information registry group 30 means that one or more thing information registries 31 to 33 exist collectively. In the RFID network environment 10, when the client 11 requests a query to the thing information URL retrieval service device 20 using the identifier recorded on the RFID tag 13 through the RFID tag reader 12, the thing information URL The search service apparatus 20 informs the URL of the thing information system related to the identifier of the RFID tag 13 in the thing information system group 40 through interaction with the thing information registry group 30.

In order to provide the client 11 with the object information corresponding to the identifier of the specific RFID tag 13, the thing information URL retrieval service device 20 interacts with the object information registry group 30 connected to the public Internet. It serves to retrieve and refine it. In addition, since the thing information may be distributed in various thing information systems on the Internet, the thing information registry group 30 may include the name resolution service 31, the XML registry service 32, and the directory service 33. There may be one or more thing information registries.

According to the thing information query of the client 11, the thing information URL retrieval service apparatus 20 composes and transmits a response message through the thing information registry group 30 interacting. At this time, the client 11 is a situation in which the identifier of the RFID tag 13 is known as a key value of the query before the inquiry process, which is the RFID tag reader 12 in the RFID network environment 10 of FIG. 1. Means that the identifier is extracted from the data recognized through the radio wave communication from the RFID tag 13.

First, the client 11 transmits a URL search query message to the thing information URL search service device 20 to obtain URL information of the thing information system corresponding to the specific RFID tag 13 identifier. Then, the thing information URL search service device 20 receives the URL search query message sent by the client 11, and then provides the thing information provided by the one or more thing information registry existing in the thing information registry group 30. Retrieve the URL of the system.

Next, the thing information URL search service device 20 removes duplicated URL information and transmits the processed result information to the client 11 as a response message. Thereafter, the client 11 may access the thing information system 40 using the URL information of the response message to obtain the thing information.

In addition, the order server 203 recognizes the ODS server 205 and the OIS server 207 as separate servers, and performs information exchange with each server, but the ODS server 205 and The OIS server 207 performs its own interworking, and the order server 203 may be provided with object detailed information only through information exchange with the ODS server 205. That is, after the order server 203 transmits the RFID code information to the ODS server 205 and requests the object detail information for each code, the ODS server 205 receives the RFID code from the OIS server 207. It may have a procedure of receiving the detailed information of the object corresponding to the transmitted to the order server (203).

Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

5 is a flowchart for explaining the main operation of the present invention. As shown, in step S501 the user reads the RFID tag attached to each article by using the RFID reader built into the mobile communication terminal 201. The user can read the RFID tag for one article or read multiple RFID tags as needed. The user sequentially reads a corresponding tag for each article using the key applying unit 301 or inputs a key signal for reading a tag for any one article.

As the key signal input by the key input unit 301 is recognized by the RFID driver 303, the RFID driver 303 transmits a frequency signal set by an RFID tag attached to each article. The RFID tag generates small power from the transmission frequency signal and transmits RFID code information stored in the RFID tag based on the small power. The RFID driver 303 receives the signal transmitted from the RFID tag and provides it to the RFID decoder 305.

In step S503, the RFID decryption unit 305 demodulates the RFDI code information from the currently received signal. The RFID code information refers to a code structure defined in ISO 11784 as coded identification information for identifying a corresponding article. This RFID code information is based on a total of 64 bits, and indicates whether or not the item that the transponder has information about the animal, ID information about the transponder, country information issued ID, transponder manufacturing Company, ID, and the issue number, that is, 0 to 274,877,906,944, including the issue number. Therefore, such RFID code information holds about 270 billion individual numbers and has a unique code for every kind of article.

In step S505, the RFID decryption unit 305 extracts the RFID code information, that is, the digitized identification number, and stores the RFID code information in the RFID code storage unit 307. Code information stored in the RFID code storage unit 307 is managed based on an input signal of the key input unit 301. The user may store code information about at least one item by using the key input unit 301, and may store code information about a plurality of items as necessary.

As for each piece of code information about the article, the code information currently read into the RFID code storage unit 307 is stored until the tag reading from the key input unit 301 is finished. Of course, the user may selectively delete the code information read up to now. After this procedure, the user requests an internet connection to obtain item details of the item using the key input unit 301 in step S509.

The server access control unit 309 receives the Internet access command from the key input unit 301, and then enables the RFID code storage unit 307 to fetch pre-stored RFID code information. The server access control unit 309 attempts a wireless Internet connection with the order server 203 through a wireless Internet network, and at least one RFID code fetched from the RFID code storage unit 307 after the Internet connection is recognized. Send the information.

From the step S511 is a flowchart showing the operation of the order server 203 described above, the operation of the different subjects described in the previous process, but for convenience of description, the operation of different subjects are described in one flowchart It should be recognized that there is.

In step S511, the order server 203 receives the RFID code information transmitted from the mobile communication terminal 201. This is done by the code receiving unit 401 connected to the internet network, and the code receiving unit 401 provides the currently received code information to the code-specific information collecting unit 403. The code information is provided sequentially as at least one information. In step S513, the code-specific information collecting unit 403 provides code information of an article currently received to the ODS server 205.

The ODS server 205 is an object directory service, that is, an RFID retrieval system, which is a service server that informs a location (URL: Uniform Resource Location) of a server that has article information related to an RFID code inserted in an RFID tag, and is a DNS (Domain). It is implemented based on the name system technology. The ODS server 205 works in conjunction with an OIS server 207, that is, an Object Information Service, that contains actual information of a tag. Therefore, the code-specific information collecting unit 403 provides the code information of the article to the ODS server 205, and requests detailed information of the article based on this.

The detailed information of the article is article information matching the code information, and represents detailed information of each code information. The code-specific information collecting unit 403 collects a plurality of item information through the ODS server 205 and provides it to the Internet page generation unit 405. In step S515, the Internet page generation unit 405 generates an Internet page based on the item information corresponding to the RFID code information.

The Internet page is detailed information on an item selected by a user, and includes information such as an item picture, price, discount information, manufacturing information (manufacturer, manufacturer, date of manufacture, etc.). Accordingly, the Internet page is a page for providing detailed information on a plurality of items that the user wants to purchase. The Internet page is generated by the Internet page generation unit 405 and then the mobile communication terminal 201 through a wireless Internet network. Is sent). The mobile communication terminal 201 displays the Internet page using a WAP browser. After checking the goods information displayed on the mobile terminal 201, the user requests an order for purchasing goods in step S517.

The purchase of goods may also be executed using a WAP browser, and the code receiving unit 401 may receive an order command input from a user and provide it to the order managing unit 407. As in step S519, in response to the user request, the order management unit 407 requests a batch of goods order based on each URL information for each item. In addition, the result of the order for the article is provided to the mobile communication terminal 201 through the Internet network, and the mobile communication terminal 201 is provided with the article order result through the WAP browser.

As described above, according to the present invention, when ordering items using an RFID tag, the detailed information of a plurality of items is collected in a batch through an Internet page, and then each item may be collectively ordered. It can be said that industrial use value is high because it can effectively manage communication resources by drastically reducing the use of wireless Internet.
