Intelligent Book Shelving system

In conventional library system following problem are there as follow: The records of book issued, book returned etc. are kept manually in

registers.

Also in big libraries it is tedious job to find out the required book.

To perform all these tasks we are developing the Library management system.

The system will be all in one which consists of facilities for finding the

books and keeping records of books issued etc.

RFID based systems are going to revolutionize the entire library automationsystems which will track the books, say whether they are issued or they are

in library, so that library user will get the instant information.

RFID can be used for library theft detection systems. RFID-based systems

move beyond security to become tracking systems that combine security

with more efficient tracking of materials throughout the library, including

easier and faster charge and discharge.

MASTER UNIT:

This unit is connected to the PC at librarians table. The entry for

books can be written on the users card using this unit. Also the data on

the users card can be read using this unit.

WORKING:

In this system every user who wants to use library facility will be

issued one card. This card will consist of specific code which will be

unique for each user. By using this card we can keep the record of the

books allotted to him/her. For each entry of the member to the library the

presence will be detected. If the member takes any book the members ID and thebook ID will be collected in the librarian section. If the member returns the book

within the due period, the member is allowed to take another book if he needs. If

he doesnt return the book within the due period and if he takes another book it

alerts the librarian about the member. This automates the library and reduces the

burden of the librarian.

In this system, there is another RFID reader which will be

connected to slave card. Slave cards are kept on the

shelves. Limit switches will be placed rows and column

wise. Different tags with different code will be attached tobooks. While keeping or taking book from shelves reader

will identify the book and limit switch which is changed

while keeping or taking the book.

In this way slave unit will find out position and send it to

the master unit via 485 interfaces. Master unit will keep

the record of position of the book and books issued to the

particular user.

Master unit:

8051 is used as controller to control total system. it continuously scans the keypad

from cupboard

RFID reader is used to read the tag and send it to pc through RS485 to slave.

Slave unit:

8051 is used to read the data received from rs485 and send data to pc
