INTRODUCTION• Developing a smart logic for automatically detect the USER which has to be issued

with the help of RFID and automatic deduction of tariff for book issue.

• tag to every user. This unique number is store in the silicon chip and placed in the identity card of every student and teacher. No one can change this code.

• This UID code is already store in the data base of library system. When any person carrying a book, reach near the exit gate then the Rf passive card reader generate a 125 kHz frequency for decoding RF tag.

• If the data base is ok then person is asked to enter his password. If everything is correct and account has sufficient balance, issue tariff is deducted and gates open automatically.

• If balance is not sufficient, account can be charged there only by paying cash .

• No person can exit library with a book without paying for it.

BASIC COMPONENTS USED

•MICROCONTROLLER 89S52

•LCD ( 2 BY 16 ) 5 BY 7 MATRIX

•MEMORY 24C02 ( SERIAL EEPROM )

•RF READER COIL & TAGS

•DC MOTOR (9V)

•KEYBOARD (MATRIX)

MODULES OF PROJECT

WE HAVE DIVIDED THE HARDWARE OF OUR PROJECT IN TWO PARTS:

• MODULE 1: ENTRY GATE

• MODULE 2: EXIT GATE

ENTRY GATE• THE ENTRY GATE OF OUR LIBRARY SYSTEM IS A

SIMPLE PASSWORD ENTRY GATE.• A PASSWORD IS ASSIGNED TO EACH AUTHORISED

USER THROUGH WHICH ACCESS IS GRANTED INTO THE LIBRARY.

• WE HAVE GIVEN THE ENTRY PASSWORD AS 1234 AND IF IT IS ENTERED WRONG MORE THAN 3 TIMES THEN MASTER LOCK WILL BE ACTIVATED WITH THE BUZZER BEEPING AND THE MASTER PASSWORD KEPT IS 9876.

• THE BASIC WORKING HAS BEEN SHOWN THROUGH THE FLOW DIAGRAM.

EXIT GATE

• THE EXIT GATE OF OUR LIBRARY SYSTEM WORKS WHEN A PERSON WANTS TO ISSUE A BOOK AND EXIT THE LIBRARY

• THEN THE RFID READER INSTALLED AT THE EXIT GATE READS THE RFID TAG .

• THE PERSON HAS TO ENTER THE PASSWORD AND THE AMOUNT FOR ISSUE OF THE BOOK IS DEDUCTED AND THE EXIT GATE OPENS.

• IF THE ACCOUNT DOES NOT HAVE ENOUGH BALANCE THEN THE USER CAN RECHARGE IT.

HARDWARE SNAPSHOT

FUTURE SCOPES

• THIS PROJECT IS A DUMMY MODEL OF THE LIBRARY SYSTEM IN WHICH THE CODING HAS BEEN DONE FOR ONLY A MAXIMUM NUMBER OF 15 STUDENTS AND 1 TEACHER.

• THIS COULD BE INCREASED IN THE PROGRAMMING FOR FUTURE SCOPES OF THIS LIBRARY SYSTEM & THE DATABASE CAN ALSO BE MAINTAINED OF THEM.

MILESTONES

• Selection of topic

• Submission of synopsisAUGUST

• References

• Basic study of projectSEPTEMBER

• Hardware of module1 entry gate.NOVEMBER

• Module 2 Hardware design(Exit gate)

FEBRUARY

• Coding of microcontroller of entry and exit gate.

• Interfacing of entry and exit gate.

• Final completion of project

• Documentation and Thesis

MARCH and APRIL

PROBLEMS ENCOUNTERED

• WE WERE PLANNING TO INSTALL TWO RF ID READER BOTH AT THE ENTRY AND EXIT GATES.

DUE TO FREQUENCY MISMATCHING SO ONLY ONE RF ID COULD HAVE BEEN INSTALLED AT THE EXIT GATE.

• THE CODING AND INTERFACING OF BOTH THE MICROCONTROLLERS WAS A BIG TASK.
