However, it will be apparent to those skilled in the art that the present invention can be applied to other than the book.

Referring to FIG. 1, a book management system includes a book management device 100, a manager computer 200, and a book management server 300.

The book management apparatus 100 recognizes an access of a book desired to be loaned / returned, and thus, detects an RFID tag attached to the book and acquires information of the book.

When the book information is acquired, the book management apparatus 100 transmits the obtained book information to the manager computer 200 so that the book is loaned or returned.

When the manager computer 200 receives the book information from the book management device 100, the manager computer 200 receives and stores the book information, and accordingly, the manager computer 200 performs a loan or return operation of the book. To be performed.

That is, the information of the book transmitted to the manager computer 200 is displayed through a separate display screen, so that the manager checks whether the book is normally returned or normally loaned.

In addition, if there is an error in the loaned or returned books, the manager computer 200 prevents the loan or return of illegal books by not allowing the loan or return.

When the manager computer 200 determines that the loan or return of the book is normally performed, the book information is transmitted to the book management server 300.

The book management server 300 stores the information of the customer who loans or returns the book, the information of the book held, and the book information or the book information returned by the customer.

That is, the book management server 300 collects book information transmitted from the manager computer 200 through a network and builds it into a database, and the constructed database is variously used according to the use environment and purpose of the book management system. It can be utilized. To this end, the book management server 300 may provide a database and a website opened on the Internet to search and browse.

To this end, the book management server 300 is building a database, and stores all the information for book management, the database data storing the RFID identification ID information and book identification ID information matching the RFID tag in the database At least one base may include a database for storing book information and a database for storing and managing customer information. The book information may include a book name, author name, synopsis, plot, summary and book review.

In addition, the book management server 300 may separately manage the preferred book information, etc. for each customer, each customer may provide the customer by managing the book status, such as monthly loans according to the loan and return status. .

Hereinafter, the book management apparatus 100 will be described in more detail with reference to the accompanying drawings.

2 is a detailed block diagram of a book management apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the book management apparatus 100 includes an I / O processing unit 110, an RFID reader unit 120, and an antenna unit 130.

The I / O processing unit 110 recognizes the access of the book, and as the access of the book is recognized, the RFID reader unit 120 and the antenna unit 130 are driven to correspond to the RFID tag attached to the accessed book. Allow book information to be obtained.

The RFID reader unit 120 is installed at the gate of the customer, and reads tag data detected through the antenna unit 130 and transmits the read tag data to the I / O processing unit 110.

The antenna unit 130 detects tag data from the RFID tag attached to the accessed book according to the RF signal generated from the RFID reader unit 120.

At this time, the antenna unit 130 is preferably implemented as an antenna of the NFC (Near Field Communication) method.

That is, the embodiment according to the present invention performs the RFID communication of the UHF band, the RFID communication of the UHF band has a disadvantage that the radio wave exposure of the RF signal is severe.

Thus, the power supply and the signal can be supplied in one line without separating the power line and the signal line, and it is easy to install the RFID reader by not using a separate external independent power supply. In addition, it is easy to manufacture the RFID reader, it is possible to lower the manufacturing cost of the product.

Here, the communication unit 121 supplies a voltage of 5V and a current of 500mA to the power supply 122, such a voltage and current is sufficient power for the RFID reader to recognize the information of the tag in a short distance Supply.

In addition, the power supply unit 33 is provided with a separate regulator to supply the 3.3V power and 1.8V power to the RFID modem 123, 3.3V power to the control unit 124.

The book management apparatus according to the embodiment of the present invention as described above operates a RFID reader only when a book with an RFID tag is approached by a separate infrared sensor to perform a more accurate task, and by applying an NFC antenna to RF Minimize propagation loss.

Thus, the embodiment according to the present invention can efficiently manage the loan and return of the article with the RFID tag, and can loan and return a plurality of items at the same time, reducing the workload of librarian staff and loan and return books It can increase the accuracy and speed of work.

5 is a flowchart illustrating a book management method step by step of the book management apparatus according to an embodiment of the present invention.

Referring to FIG. 5, the infrared sensor 114 included in the book management apparatus 100 continuously checks whether there is a book approaching the surroundings (step 100).

In this case, when the book approaching the periphery is detected, the infrared sensor 114 transmits a detection signal indicating that the book is detected to the controller 115.

In operation 110, when the detection signal indicating that there is a book approaching the surroundings is transmitted through the infrared sensor 114, the controller 115 generates an RFID communication start signal according to the transmitted detection signal (step 110).

That is, the controller 115 allows the book information according to the RFID tag attached to the detected book to be acquired through the RFID reader 120 at the time when the book approaches.

At this time, the RFID reader unit 120 stops tag data recognition operation before the detection signal is transmitted through the control unit 115, and the operation is performed when the operation start signal is transmitted through the control unit 115. Will begin.

When the operation start signal is transmitted, the RFID reader unit 120 acquires information of the book from the RFID tag attached to the book approaching the surrounding (step 120).

In addition, when the book information is obtained, the RFID reader unit 120 transfers the acquired book information to the I / O processing unit 110.

When the book information is delivered, the I / O processing unit 110 confirms a task to be processed according to the delivered book information (step 130).

For example, the I / O processing unit 110 checks additional information according to the currently accessed customer, the currently accessed book, and whether the book is a loan or return.

In addition, when the additional information is confirmed, the I / O processing unit 110 transmits the confirmed additional information to the manager computer 200 through a network (step 140).

According to the embodiment according to the present invention as described above, it is possible to efficiently manage the loan and return of the article with the RFID tag, and it is possible to borrow and return a number of items at the same time, reducing the work load of the librarian staff Increase the accuracy and speed of loans and returns.
