9. PROJECT PRESENTATION:2012 • Tool & Resource : • SOFTWARES: • PROTEUS VERSION 7.0 • KEIL version 4.0 • TOPWIN 6.0 • EXPRESS PCB • HARDWARES: • Breadboard • Power supply • 8051 microcontroller • L293D IC • MAX232 IC • RS232 ports • RFID transmitter and receiver • motor • printed circuit board • Wires and Solder RFID BASED ACCESS CONTROL SYSTEM

10. PROJECT PRESENTATION:2012 • Concept used : • 8051 Microcontroller: • A 8051 microcontroller have • 4 ports and each ports • Having 8 pins. • It is 40 pins IC • 4k ROM(on chip program • Space in bytes) • 128 bytes RAM • 2 Timers • 32 I/O pins • 1 serial ports • 6 Interrupts sources RFID BASED ACCESS CONTROL SYSTEM

11. PROJECT PRESENTATION:2012 • RS232: • To allow compatibility among data communication equipment. • It is in DB 25 and DB 9. • It is most widely used in serial I/O Interfacing standard. • The I/O are not TTL compatible, In RS232 1 is represented by • -3 to-25v ,While a 0 bit is +3 to +25v ,making -3 to +3 undefined we must use a voltage converter such ac MAX232. RFID BASED ACCESS CONTROL SYSTEM

12. PROJECT PRESENTATION:2012 • MAX232 IC: • It is 14 pin IC. • A line driver such as the MAX232 chip is required to convert RS232 voltage levels to TTL levels, and vice versa • 8051 has two pins that are used specifically for transferring and receiving data serially. • These two pins are called TxD and RxD and are part of the port 3 group (P3.0 and P3.1). • These pins are TTL compatible; therefore, they require a line driver to make themRS232 compatible. RFID BASED ACCESS CONTROL SYSTEM

13. PROJECT PRESENTATION:2012 • L293D: • It is 16 pin IC. • The L293D device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL & TTL logic levels & drive inductive loads(such as relays solenoids, DC and stepping motors) and switching power transistors. • It is use as a motor driver.

14. PROJECT PRESENTATION:2012 • LCD: • It able to display numbers characters, and graphics. • It has 14 pin RFID BASED ACCESS CONTROL SYSTEM

15. PROJECT PRESENTATION:2012 Circuit Diagram : RFID BASED ACCESS CONTROL SYSTEM

16. PROJECT PRESENTATION:2012 • Working : • Low frequency RFID works on the principle of radio waves and at the frequency of 125 KHz. • There is a coil inside the RFID tag and when it is influenced by magnetic field, it sends an identity code to a device for further processing. • The RFID tag is used as an identity for a particular user. If the identity (serial number of the tag) of the user is matched with the one already stored in this system, he gets immediate access through it. • In beginning, the user is prompted to scan his tag or ID. The serial code of the tag is identified by the reader module and is sent to AT89C51 for checking. RFID BASED ACCESS CONTROL SYSTEM

17. PROJECT PRESENTATION:2012 • If the ID is matched by the microcontroller, the user gets the access. On the contrary, if the tag is not identified, a message (‘Access Denied’) is displayed on LCD screen. RFID BASED ACCESS CONTROL SYSTEM

19. PROJECT PRESENTATION:2012 • Application: • Security Purpose • Unauthorized Access Control • Automated database updation RFID BASED ACCESS CONTROL SYSTEM

20. PROJECT PRESENTATION:2012 • Advantages: • An RFID smart card-based system may reduce operation costs in the long run. • RFID equipment damage occurs much less frequently than is the case with magnetic strips or bar codes present on Charlie Tickets. RFID BASED ACCESS CONTROL SYSTEM

21. PROJECT PRESENTATION:2012 • Disadvantage: • In the short run, costs of diffusion and implementation for an RFID access control system is more. • Poor read rate can occur if the reader and receiver are not properly aligned. RFID BASED ACCESS CONTROL SYSTEM
