The
microcontroller: The microcontroller does most of the addressing and
instruction execution through its data, address and control busses.
The
Keypad: The keypad is used for selection i.e. As an input device to
issue instruction to the control processing unit (CPU) of the processor.
The smart card and its associated pin: provide the security system.
The Display Module: the display module shows the output of events that are taking place.
The
Electromagnetic Relay: The help of the relay is utilized by the CPU to
switch the motor ON which moves or turns causing the gate/door to slide
to the defined direction.
The Alarm Unit: The alarm unit produces an alarm signal when a wrong password or pin code is entered more than three times.
The power supply Unit: The power supply unit supplies a voltage for optimum operation of the circuit.
In all, this project demonstrates the integral function of what is obtainable in real system.
1.1 AREAS OF APPLICATION
This
project is applicable in areas where unauthorized personnel are
restricted from access as can be seen in Offices Hotels Residential
quarters Banks Security System Credit or ATM cards Authorization card
for pay television Sims for mobile phones
1.2 AIMS AND OBJECTIVES
The
major aim of this project is to construct a system that uses two-factor
authentication (smart card and their associated pins) to provide
security control to
reduce the threat of authorized access to some
restricted areas. It also aims at bridging the technological gap between
developing and developed countries of the world.
1.3 PROJECT SCOPE
The
construction of security door using smart card is based on discrete
components like resistors, transformers, Liquid crystal display,
transistors, relays, microcontroller, D.C motor, diodes, bridge
rectifier, bolt and nuts, aluminum etc. This project design can be
mounted on hotels door, office door etc with the incorporation of big dc
motor and thyristor that will be able to drive specially constructed
sliding gate/door when activated.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis project shows the construction of a microcontroller based security door using smart card. It is aimed towards programming the microcontroller to control the hardware in sliding door. The system consists of a microcontroller 89S52 which sends a signal to the multiplexers on insertion of the smart card in the card slot. The multiplexers consist of ICS which prompts for a display of the identity of the card user in the liquid crystal display (LCD). The LCD displays the status of the ca ... Continue reading---
