Description

Wireless Communication Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication device. More particularly, the present invention relates to a wireless communication device that connects to a server using connection information of a server corresponding to an RFID tag, and receives and displays detailed information of an article with an RFID tag from the server. Relates to a device.

In the past, the Internet, which was confined to a specific class, became widespread through the implementation of the Web, which had a great impact on the digital industry as a whole. Internet-based services and content distributed through the Internet have become the yardstick for the digital industry in the 21st century. In addition, as the multimedia of contents has been realized through the high speed of the internet network, mobile phones, PDAs, notebooks, etc., multimedia has become an essential item, not an option.

Meanwhile, the concept of computer-based information communication is changing to the concept of ubiquitous. Ubiquitous is a Latin word meaning that it exists anytime, anywhere. It means an information and communication environment where users can freely access the network regardless of the network or computer.

The core of ubiquitous computing is RFID (Radio Frequency Identification), which is a diagram showing a conventional RFID system.

The RFID system includes a transponder 11 that stores unique information, a transceiver (reader or reader) 12 that reads and decrypts functions, a server (host computer) 13, a network 14, and an application program ( For example, an application program based on manufacturing and logistics information such as enterprise resource planning (ERP) and supply chain management (SCM).

Transponder 11, commonly called a tag, is composed of an IC (Integrated Circuit) chip and an antenna, and has various shapes and sizes. Transponder 11 implanted under the skin to track the animal is as small as a pencil lead diameter is only 1cm in length. The main functions of the IC chip are the data storage, the memory size (25 bit ~ 512 kb or more), the memory type (read-only, read-write type, write once and read multiple times), memory type (Electrically Erasable Prices vary depending on Programmable Read-Only Memory (FRAM) and Ferroelectric Random Access Memory (FRAM).

The RFID system may be classified into an inductively coupled method and an electromagnetic wave method according to a wireless access method. The mutual induction method is short-range (within 1m), the electromagnetic wave method is used for medium and long distance RFID, the mutual induction method uses a coil antenna and the electromagnetic wave method uses a high frequency antenna to wirelessly connect to each other.

In mutual induction, the transponder 11 is operated almost manually. In other words, all the energy required for the operation of the IC chip of the transponder 11 is supplied by the transceiver 12. Thus, the antenna coil of the transceiver 12 generates a strong magnetic field in the surrounding area. A portion of the emitted magnetic field generates an inductive voltage at the coil antenna of the transponder 11 away from the transceiver 12, rectifies and supplies it with energy for the IC. The electromagnetic wave transponder 12 does not receive enough power to drive the IC chip from the transceiver 12, and thus includes an additional battery for long-range recognition (active type).

The transceiver 12 and the transponder 11 process baseband data using various digital codings. The wireless signal is mainly converted into a high frequency signal and transmitted using a basic three digital modulation schemes, namely, Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). However, in a specific frequency band (UHF band of the United States), only a specific modulation scheme is required to reduce the human body influence of electromagnetic waves or interference with other communication systems, and the most widely used is spread spectrum (SS). Among the frequency spreading methods, a direct sequence (DS) used for a CDMA mobile phone or a wireless LAN and a frequency hopping (FS) used for Bluetooth are mainly used. However, applying such a modulation scheme to a tag requires a more complicated circuit and increases the price, so in practice, only the transceiver 12 uses this modulation scheme, and the transponder 11 covers the entire frequency of frequency spreading. And transmit the signal using ASK.

In addition, various signal processing is performed to increase the reliability of data information, such as an error rate reduction method using a method such as cyclic redundancy check (CRC), Aloha or the like used in a wireless LAN to distinguish multiple transponders 11. An anti-collision method using a similar method to Carrier Sense Multiple Access (CSMA), a data security method using a symmetric or asymmetric encryption algorithm to protect data, and the like are applied. In particular, such signal processing depends on the functionality of the memory of the transponder 11.

Meanwhile, the transponder 11 may be used to access data stored in the server 13 through the network 14, and the data may be stored in different servers for each transponder 11.

Therefore, the emergence of the invention which makes it possible to easily connect to a server providing data for each transponder 11 is required.

At this time, the communication unit 410 may refer to the access information specified in the request message. In addition, the communication unit 410 may perform a role of transmitting detailed information to the provided monitor device.

The communication unit 410 may transmit and receive baseband data by using the RFID tag 210 and various digital codings. ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying) are mainly digital modulation methods. By using PSK (Phase Shift Keying), a wireless signal obtained by converting a base signal into a high frequency signal may be transmitted and received.

The controller 440 extracts the access information or the access code of the information providing server included in the RFID packet received from the RFID tag 210. That is, as illustrated in FIG. 3, the RFID packet includes access information or an access code of the information providing server, and the controller 440 extracts the access information. Meanwhile, in the practice of the present invention, the access information extracting unit 470 may extract the access information of the information providing server based on the access code.

Here, the access information or access code is preferably included in a predetermined position of the RFID packet. Accordingly, the controller 440 may extract access information by accessing a specific location without analyzing the RFID packet.

In addition, the access code may be included in the RFID packet in a predetermined format. For example, the RFID tag may be in accordance with the EPC or ISO standard, in which case the access code may be "E", and in accordance with the ISO standard, the access code may be "I". Accordingly, the RFID transceiver 400 may select an analysis algorithm for the RFID packet using the received access code.

In addition, the access code may include a letter indicating the manufacturer of the product. For example, in the first manufacturer, the letter "A" may be included in the access code, and in the second manufacturer, the letter "B" may be included in the access code.

In addition, the access code may be configured in the form of a string by combining a letter corresponding to the RFID standard and the character representing the manufacturer of the product. For example, if the RFID tag for a product from a first manufacturer conforms to the EPC standard, the access code may be "EA", and if the RFID tag for a product from a second manufacturer conforms to the ISO standard, that access code May be "IB".

As such, as the access code is configured according to a preset format, the RFID transceiver 400 may easily analyze the access code. To this end, the RFID transceiver 400 may receive an analysis algorithm corresponding to the code system from the information providing server or the integrated management server, and the controller 440 may use the corresponding RFID packet by using the analysis algorithm corresponding to the received RFID packet. To analyze.

If the RFID packet received from the RFID tag includes an access code other than the access information, the access information extractor 470 may use a table (not shown) in which the access information and the access code matched with the access information stored in the storage 430. Reference information may be extracted by referring to.

In addition, the connection information extractor 470 may extract the access information using the information included in the RFID packet. As described above, the EPC region of the RFID packet may include an object class and a serial number, and the access information extractor 470 extracts the access information using a table (not shown) to which the access information for each object class is matched. Alternatively, the access information may be extracted using a table (not shown) having a matching range of serial numbers.

The controller 440 performs overall control of the communication unit 410, the storage unit 430, the location checking unit 450, the message generating unit 460, and the connection information extracting unit 470. It can also play a role in relaying data.

The message generator 460 generates a request message for requesting detailed information of an item to which the RFID tag 210 is attached. In generating the request message, the message generator 460 may insert the access information received from the controller 440 into the destination field of the request message.

In addition, the message generator 460 may generate a response message only when receiving an authentication request packet including a specific identifier from the RFID tag 210, the RFID tag 210 only when receiving a response message tag Information can be sent.

Here, the message generator 460 may determine the generation order of the response message by referring to the priority given to the specific delimiter.

As the request message is transmitted, the communication unit 410 may receive detailed information of the article from the information providing server, and the received detailed information may be temporarily stored in the storage unit 430 and again through the communication unit 410. Can be sent to the monitor device. In addition, the detailed information may be transmitted directly to the monitor apparatus through the communication unit 410 without temporarily storing the detailed information in the storage unit 430.

The storage unit 430 may include a hard disk, flash memory, compact flash card, compact digital card, secure digital card, smart card, multimedia card, or memory stick. As a module capable of inputting / outputting, a module may be provided inside the wireless communication device 400 or may be provided in a separate device.

The positioning unit 450 refers to the location information received from the location tracking module, such as a GPS (Global Positioning System) module attached to the RFID tag 210, and checks the location of the corresponding article. When the location tracking module is installed at 400, the location information of the RFID transmitter 400 may be checked. On the other hand, the location of the article or location information of the RFID transmitter and receiver 400 confirmed by the positioning unit 450 may be included in the request message generated by the message generator 460 and transmitted to the information providing server.

In addition, when the RFID transceiver 400 is installed at a fixed position, the monitor devices 221 and 222 may use the unique information (IP address or MAC address, etc.) of the RFID transceiver 400 to determine the RFID transceiver 400. In addition, the monitor apparatuses 221 and 222 may use a table (not shown) in which the unique information of the RFID transceiver 400 is matched with its location. Here, the table in which the unique information of the RFID transceiver 400 matches the location may be stored in the monitor devices 221 and 222 and the information providing server 231, 232, 233, and 234 or the integrated management server 640.

6 is a view showing an article code accessible by login information according to an embodiment of the present invention.

That is, the RFID transceiver 400 receiving the RFID packet from the RFID tag 210 may transmit the login information input through the input unit 420 while accessing the information providing server using the access information included in the RFID packet. In this case, the information providing server may access the item code corresponding to the received login information and extract detailed information about the corresponding item.

For example, if the login information 1 610 is received, the information providing server may extract detailed information of the article having the article code 611 called AB221236, and if the login information 2 620 is received, the information providing server. Is capable of extracting detailed information of an article having article codes 621 called AB435678 and AB435679.

In addition, whether or not access to the detailed information of the specific item may be determined according to the login information. For example, when accessing the login information 1 610, it is possible to access the article code 611 called AB221236, but when accessing the login information 2 620, access to the article code 611 called AB221236. As impossible, the range of accessible product codes can be determined for each user's rating.

In addition, the type of information that may be provided may vary according to the user rating. FIG. 7 is a diagram illustrating a correspondence relationship between login information and accessible information according to an embodiment of the present invention. When logging in with login information A, only product information and production information may be provided, and when logging in with login information B. FIG. The figure shows that not only information and production information but also cost information, customer information and shipping information can be provided.

That is, as the user grade of the login information A and the user grade of the login information B are different, the type of information that may be provided may vary.

In addition, the type of accessible information may vary according to the identifier of the RFID tag. For example, when the identifier of the RFID tag is included in a preset range, access to specific information is allowed. When the identifier of the RFID tag is outside the preset range, access to the corresponding information is restricted.

In addition, when the identifier of the RFID tag is included in the preset range, the RFID transceiver 400 may extract the connection information corresponding thereto and access the information providing server. To this end, the RFID transceiver may store a range of identifiers and corresponding connection information. The stored information may be updated by a user through a monitor device.

Referring back to FIG. 6, a request message and login information for requesting detailed information of an item may be transmitted to the integrated management server 640. The integrated management server 640 is a device provided separately from the information providing server. Overall management of the entire information providing server may be performed, and a table (not shown) matching the login information and the corresponding information providing server may be managed. On the other hand, in the practice of the present invention, it may be to receive the login information directly from the information providing server without the integrated management server 640.

Accordingly, when the RFID transceiver 400 transmits the request message and the login information to the integrated management server 640, the integrated management server 640 accesses the information providing server corresponding to the request message and supplies the corresponding log information. After extracting the detailed information of the article having the code may respond to the RFID transceiver 400.

In addition, the table 700 of FIG. 7 showing the correspondence relationship between the user level of the login information and the accessible information may be stored in the information providing server or the integrated management server 640.

6 shows that the integrated management server 640 having received the login information 3 630 extracts detailed information of the article having the article code 631 as AB435682.
