Description

Library system using RFID and its method {SYSTEM AND METHOD FOR BOOK MANAGEMENT USING RFID}

The present invention relates to a library system, and more particularly, to a library system and a method for reserving, lending, and returning a book more simply and quickly using RFID.

In general, each library operated by a school or public institution has a large amount of academic and general books for students or the general public. Library users can browse the various books in the library and apply for a loan to the library if they want to borrow a particular book and return the loaned book before the end of the loan period.

However, the existing library is in the stage of expanding quantitatively and qualitatively, resulting in serious library problems. In particular, a large number of people and time are given to libraries used for opening classes, schools, and public period libraries to organize books according to the movement of books. However, there is a limit to the employment of manpower, which necessitates a separate library system.

One of the problems with existing libraries is that even if the books are not stolen or damaged, people must find them and move them back to their original location if they are not in their original designated location, which can easily be done if the book is large. It is not a thing.

Therefore, if the user wants to find a book in the library when the book's position is out of the designated position, the user can know the fact that the book exists in the library through the loan history of the book, but the book is not known because the book is in the correct position. You will not be able to touch. No matter how many books are in the library, if the user cannot read the book he wants due to the lack of organization of the books, the existence of the library itself may be meaningless.

In addition, even if the book organization is complete, if the book is searched using a PC installed in each library, the location information of the book is provided in the form of `` X-floor XX library XX bookshelf ''. In order to check whether it is plugged in, the title of the book is checked for the entire bookshelf and the desired book is obtained.

An object of the present invention is to provide a library method and system using RFID to solve the fundamental problem of time and effort required to find a book in a library.

In addition, an object of the present invention is to provide a library method and system using RFID that provides an optimal process for the process of booking, lending, returning books.

In particular, it is an object of the present invention to provide a library library method and system using RFID, which enables a library user to receive a service for a book with minimal walking and shortest time.

The present invention includes the steps of retrieving location information for at least one registration book; And providing map information of the shortest distance for visiting the registration book based on the location information of the registration book.

The present invention provides a book information database storing book information and location information of all books provided in a library; A library module for retrieving location information of at least one registered book according to a user's inquiry request command; And a shortest path module for providing map information of the shortest distance for visiting the registered book based on the location information of the registered book.

The present invention performs library library such as reservation, loan, and return using RFID, and provides the shortest distance in the library by using the location information of the book that the user wants to find. Accordingly, the library system according to the present invention provides a new library process that can minimize the time it takes for a user to find at least one book.

The present invention improves user convenience for using a library and minimizes time and effort required for a user to search for a book by providing a shortest path of moving book (map information) with respect to a book list to be searched by the user.

In addition, even when the book is returned to its original location after returning the book, the shortest route of movement (map information) can be provided, thereby minimizing time and effort required to bring the book.

Hereinafter, a library system and a library method using RFID according to the present invention will be described with reference to the accompanying drawings.

The configuration of a library system using RFID according to the present invention will be described with reference to FIG. 1 is a view showing the configuration of a library system using the RFID of the present invention.

As shown, the present invention provides a library system 110 that manages not only basic book information but also book reservations, loans, and returns for all books provided in a library.

Libraries system 110 of the present invention includes a library server 111, a library module 112, a book information database 113, the shortest path module 114.

The book information database 113 stores various book information including location information of each book in the library, and reservation information, loan information, or return information for each book.

The location information of each book can be read through a reader installed in the library, in which case real-time location can be determined.

The library module 112 performs book reservation, loan and return processing of the user and stores the result in the book information database 113. In addition, the library module 112 may search the book information, that is, reservation information, loan information, or return information of the book, for the book that the user requests for inquiry, and provide the result to the user.

The shortest path module 114 calculates and provides a path of the shortest distance so that the user can visit and find the book more quickly based on the location information of each book with respect to the at least one book list requested by the user.

The library server 111 serves as a web server for providing book information stored in the book information database 113 in a web environment. When users on the web request a book search, the library information is searched for the book information stored in the book information database 113 through the library module 112 and the result is provided to the user.

Libraries system 110 of the present invention preferably uses RFID for library library in the library, each book is equipped with a book tag 118 using RFID.

The book tag 118 has a unique identification number for identifying an individual book, and stores information for managing the book, for example, a management number, reservation / loan / return information, location information, and the like.

Libraries system of the present invention further includes a book-only terminal 116 for the user to check the book and confirm the reservation, loan, return information of the inquired book.

The book-only terminal 116 includes a function selection unit (not shown) for inputting a user command such as inquiry, reservation, loan, and return for a book. The book-only terminal 116 transmits a user command input through the function selection unit to the library module 112 and displays a result provided by the library module 112 according to the user command. Play a role.

In particular, the book-only terminal 116 serves as a display means for displaying map information including the shortest route provided by the shortest route module 114. Accordingly, the book-only terminal 116 guides the moving line in the library along the shortest path so that the user can visit and find the book quickly.

The book-only terminal 116 is a terminal for registering a user's reservation, loan or return for a book, and includes an RFID reader 117 that can recognize the book tag 118 mounted on a book. Can be. That is, the book-only terminal 116 recognizes the book tag 118 of each book through the RFID reader 117 and recalls the processing result of the book according to a user command (reservation, loan, return). Transfer to library module 112. The RFID reading unit 117 of the book-only terminal 116 recognizes the user tag 170 assigned to the user as well as the book tag 118 and outputs the processing result of the book together with user information. It is desirable to forward to 112.

The book-only terminal 116 may be configured as a terminal that performs data input / output in a wireless manner with the library module 112 to be portable and mobile in a state possessed by a user.

On the other hand, the user may access the library server 111 by using a user terminal 130 that can access the Internet from outside the library. The user terminal 130 may use a personal computer or a portable terminal capable of internet communication.

When the user terminal 130 is portable, the book-only terminal 116 may be replaced with the user terminal 130.

In order to access the library server 111, the user may have a user tag 170 that stores an identification number pre-assigned from the library. The user tag 170 is also configured as an RFID tag, has a unique identification number for identifying a user, and may store book management information of the user, that is, reservation / loan / return information.

The user terminal 130 includes an RFID reader 150 for recognizing the user tag 170 and performing a write role on the user tag 170.

The user terminal 130 may perform a user authentication process by transferring the identification number of the user tag 170 recognized by the RFID reader 150 to the library server 111.

The library server 111 registers a reservation or a loan for the book after performing the inquiry of the book requested by the user through the library module 112 and lists the book (hereinafter, 'reserved book list'). Or a list of books (hereinafter, referred to as a 'registered book list') in which the loan is registered is stored in the book information database 113.

In detail, the library module 112 first determines whether or not each book requested by the user can be loaned under the control of the library server 111. The book is stored in the user's registration book list in the case of a book that can be borrowed according to the loan availability, and the book is stored in the user's book list in the case of a book that is not available for loan.

The library server 111 transmits a list of registered books and a list of reserved books to the user terminal 130. The user terminal 130 receives the registration book list and the reservation book list from the library server 111 and writes to the user tag 170 through the RFID reader 150.

Here, the registration book and reservation book list, as shown in Figure 2 is composed of the identification number (ID) of each book corresponding to the registration book list and the reservation book list with the corresponding user identification number (ID). Therefore, when the user visits the library while holding the user tag 170, the user can use the loan book list and the reservation book list registered on the web without going through a separate book search process in the library.

The library server 111 periodically manages the availability of each book corresponding to the book list, and when a book is transferred to the loanable state, the library server 111 may borrow the book for the book in question. Can be informed. At this time, the book is transferred to the loanable state is preferably deleted from the book list stored in the book information database 113 is added to the list of registered books.

Library system 110 of the present invention further includes an RFID reader 115 for recognizing the user tag 170 of the user visiting the library. The RFID reader 115 may be installed at an entrance to perform an anti-theft function of a book.

The RFID reader 115 recognizes a user's identification number (ID) through the user tag 170 and at the same time recognizes a list of registered and reserved books of the user stored in the user tag 170. The RFID reader 115 transmits a list of registered and reserved books of the user to the library module 112 together with the recognized user identification number.

By such a configuration, the library module 112 receives an identification number of the user who visited the library, a list of registered books and a book, and reads a list of registered books of the user.

The library module 112 retrieves location information of each book corresponding to the list of registered books from the book information database 113 and transmits the location information of the books to the shortest path module 114.

At this time, the shortest path module 114 calculates a moving line for sequentially visiting the books in the registered book list based on the location information of the books received from the library module 112. In particular, the shortest path module 114 calculates and provides the shortest distance moving line (map information) with respect to the distance position of each book.

The shortest path module 114 delivers the calculated shortest distance moving copper wire to the book-only terminal 116 and provides map information of the shortest distance for visiting the book to the user through the book-only terminal 116. .

Referring to Figure 3 will be described the entire process of the library method using the RFID according to the present invention.

3 is a diagram illustrating a whole process of a library method using RFID according to the present invention, and illustrating a process of providing map information in a sequence of distances based on location information of a book.

As shown, first receives a user's registration book list through the user authentication (S300). The list of registered books may be any one of a list of registered books in which a user directly inquires or requests a loan through the book-only terminal 116, or a list of registered books stored in the user tag 170.

It is determined whether the number of books corresponding to the list of registered books is greater than the preset maximum number of inquiry registration (S310). By setting the maximum number of inquiry registrations, it is possible to limit the number of books that can be inquired at a time and to set no more inquiry registrations.

If the number of books in the list of registered books is greater than the maximum number of inquiry registration, it is preferable to output an error message indicating that the inquiry registration is impossible and to stop the inquiry process for the book.

On the other hand, if the number of books in the list of registered books is less than the maximum number of search registration, continue the inquiry process for books and read the location information of each book (hereinafter referred to as "registered books") corresponding to the list of registered books Comes (S320). In step S320, the location information of each registered book may be read by searching the information stored in the book information database 113, or the location information of the registered book may be read in real time by controlling a reading unit installed in the bookshelf. .

A distance order (hereinafter referred to as a "visit order") is configured to sequentially visit each registration book based on the position information of the read registration book (S330), and map information that is a moving line in the library based on the visit order. It provides to the user (S340).

In the present invention, the visit order for the registration book is preferably determined by calculating the shortest path to guide the fastest moving route for all the registration books corresponding to the list of the registration books.

Referring to FIG. 4, a process of providing map information of the shortest distance to the list of registered books will be described in detail. FIG. 4 illustrates a detailed process of step S330 of FIG. 3, that is, a process of determining a shortest moving moving line based on location information of a registration book.

The distance between the registration book and the registration book is calculated from the location information of all the registration books corresponding to the registration book list and stored therein (S410).

In addition, for each registered book corresponding to the list of registered books, a distance from a predefined entrance location is calculated, and a distance from a predefined exit location, respectively. At this time, the registration book closest to the entrance is fixed to the first point of the visit order and the registration book closest to the exit is fixed to the last point of the visit order (S420).

And, based on the registration book corresponding to the first point and the last point of the visit order, the number of cases of all possible visit order for the remaining registered books is listed (S430). Subsequently, the visit order is determined as having the shortest distance among the numbers in all cases using the calculated distance between the registered books and the registered books (S440).

5 is a diagram showing an example of map information in a visiting order for guiding the book position. As shown, if the user's list of registered books consists of books from books 1 to 5, the book 2 closest to the entrance is the first point in the visit order and the book 4 closest to the exit is the last point in the visit order. It will be. The book 1, book 3, and book 5, except for book 2 and FIG. 4, are listed for all cases that can be visited after book 2. For each of the above cases, the distance between the registration book and the registration book is compared and the case having the shortest moving line is selected to determine the visit order of the registration book.

As shown in FIG. 5, the shortest distance map information indicates the location of each registered book in the library with respect to the list of registered books of the user, and includes a registered book including an entrance and an exit so that the user can visit the registered books in sequence. Guides the movement of traffic to the registration book.

Therefore, the user may visit the registration books in sequence along the shortest moving path, and thus, even if the user visits the plurality of registration books, the user may find the book with the shortest visit path and the minimum required time.

When the user finds all the registered books corresponding to the list of registered books, the user completes the user authentication with his identification number (user tag 170) through the RFID reader 117 built in the book-only terminal 116, and then The book tag 118 of the registered book can be recognized to directly perform the book loan process.

When the user registers the loan for the registered book, the book-only terminal 116 manages the book as a loan book list of the user and stores the book in the book information database 113.

Next, the return process for the loan book will be described in detail with reference to FIG. 6.

6 is a view showing the entire process of the book return method in the library method using RFID. The book return process described below is performed by the user using the book-only terminal 116.

First, an identification number of a user requesting a book return is input (S610). The identification number of the user is that the user near the user's tag 170 to the RFID reader 117 of the book-only terminal 116, or the RFID reader 117 is activated in accordance with a user command to the The user tag 170 may be automatically recognized.

The user is determined from the input identification number, and the list of loan books of the corresponding user is searched in the book information database 113 (S611). As a result of the search, it is determined whether a list of loan books corresponding to the user identification number exists (S612).

If the loan book list does not exist, a notification message indicating that there is no loan book is output (S613) and the book returning process is terminated.

On the other hand, if there is a list of loan books corresponding to the user identification number receives the identification number of each loan book corresponding to the loan book list (S614). The identification number of the loan book is activated by bringing the book tag 118 of the loan book which the user wants to return to the RFID reader 117 or in response to a user command in the RFID reader 117. 118) may be automatically recognized.

It is determined whether there is a delinquency for the loan period for each loan book in which the identification number is input (S615), and a delinquent fee for each loan book is calculated by adding a delinquent fee per unit period to the loan book whose loan period is overdue. (S616).

It is determined whether the payment for the late fee of the loan book is calculated (S617). If the late fee is not settled, a list (for example, the overdue book list) is generated and stored for the book in which the late fee exists (S618). ).

On the other hand, if there is no book overdue the loan period or the payment of the late fee of the loan book is completed, it is determined whether there is a book not returned in the list of the loan book (S619).

As a result of the determination in step S619, if all books in the loan book list are returned and there are no books returned, a notification message indicating that the book is returned is output (S620). And after outputting a notification message indicating the number of the books (S621) and ends the book return process. In the case of the registered book that has been returned, the book is deleted from the list of loan books.
