SMART CARD BASED DOOR LOCK SYSTEM
1. Scope of work Understanding of IR sensor and its importance.
Microcontroller programming in C language.
Understanding of ‘Embedded system’
PCB designing and Circuit designing of circuit.
PCB development, Component mounting and soldering.
Testing of the circuit
2. IntroductionSmart card systems are widely used by many different organizations to provide both
convenience and security. Hotels use them for room access; credit card companies
use them for handling purchases, and college campuses use cards for both building
access and electronic payments.
A smart card is a type of plastic card embedded with a computer chip that stores and
transacts data between users. This data is associated with either value or information or
both and is stored and processed within the card’s chip, either a memory or
microprocessor. The card data is transacted via a reader that is part of a computing
system.
Through this project we presented the prototype of ‘Smart card’ which is also used to
control the door lock system.
3. MotivationSmart card system is one of the safest mode to lock the home as to unlock the door that
particular swap card is required. Until and unless that swap card is not used to unlock
the door, no one can succeed in order to enter the home by the means of door in which
this system is installed. The main reason behind designing this project is to decrease
number of robbery and burglary in the city and especially in metropolitans. As today’s
generation is working, security is very important for their home. Hence, to provide
better security system we have designed the following system.
4. Objective(s)The fundamental requirements for the smart card based door lock system
remained fixed throughout the design process. The goal was to design a system
which would allow the user automated and convenient access to the door system. The
fundamental objectives of the system include:
Programming in proper manner
Interfacing to be done in a right manner
5. Project OverviewIn the project the name of the components which were used in it are as follows:
1) IR sensor
2) Microcontroller
3) Motor driver
4) Dc motor
Here as the person enters the card it passes through the area where IR sensor is placed
.Once it crosses that area the system came to know that some card is entered and drives the
motor to move the card inside passes to a certain limit. After reaching a particular point, it
will be stopped. The; card consists of a particular pattern of holes which will be detected
;either hole is present over there or not if its present then it will ask for the password .Now
you have to enter the password in between if the entered code is wrong and it happens for
three times then it will cancel whole task and makes you unable to collect the card otherwise
the system will unlock if code is correct.
We will be using 8 bit ATMEL microcontroller AT89S8253. It is a low-power, high-
performance CMOS 8-bit microcontroller with 12K bytes of In-System Programmable
(ISP) flash program memory and 2K bytes of EEPROM data memory. It has 32
programmable input output lines. The resulting architecture is more code efficient. Outputs
from port pins of the microcontroller are fed input pins of motor driver.
6. Description of workingInsert the card in the card slot, it will ask for the password. Enter the password and the door
will get unlock. But while operating this system you must keep in mind that the code which
you are entering should be the correct one, in case it is wrong for the three time then you
will loose your card.
