Design And Construction Of Rfid Based Garage Door Entry

ABSTRACT

The RFID Garage Door Entry System team is a project team which seeks to create an automation solution using a relatively un-harnessed technology called Radio Frequency Identification (RFID). Using RFID technology, the team seeks to combine the functionality and convenience of automated remote transmission with an existing garage door opener system. The intent of this project was to build a system that allowed a garage door to open wirelessly with no interaction from the user.

This system demonstrates a RFID based garage door system wherein once the correct code or password is entered, the door is opened and the concerned person is allowed to enter the garage. Again if another person arrives it will ask to enter the password. If the password is wrong then door would remain closed, denying the access to the person.

 

CHAPTER ONE

1.1                                                        INTRODUCTION

The security situation in many parts of the world today leaves much to be desired. In Nigeria particularly, the prevalence of armed robbers and other groups that constitute nuisance to the society has led to the loss of lives and properties worth millions of dollars. Many of the attacks that led to the loss have occurred in the homes or in guarded compounds and the attacks took place in spite of the existence of seemingly impregnable security gates that were designed to ward off intruders. The needs for electronically controlled gates that have superior security features to those operated manually thus exist and have been on the increase in recent times.

The RFID Garage Door Entry System team created a product which will automate the operation of a typical garage door using RFID technology. With the technology used in garage door control, a simple idea is explored: How to make a garage door open automatically upon arrival, without the push of a button. The RFID garage door opener system will consist of two major components: a reader and a tag both of which will communicate wirelessly with each other. The stationary reader will be located in the garage and will initiate all communication sequences. When a tag is in range it will then respond to the reader. The tag will validate the reader, and the reader will validate the tag. The tag will be located within the car but will not be physically embedded. This is to allow versatility of the product, such as switching a tag between automobiles, and also due to the goal of this product to be easily installable. The desire to utilize a new technology in a familiar situation is a motivating factor for this project. RFID is a relatively untapped technology that has perfect applications in secure home automation. Upon reception of this RF signal by the receiver module, another microcontroller activates a driver circuitry to operate the gate automatically. Some advantages of the system over those described in and include:

(i) It does not need close contact to control the gate; the control can be done from inside the car at a distance.

(ii) It operates as a stand-alone system and does not require a network provider for reception of signals.

(iii) The use of a keypad to generate the code necessary for the opening and closing of the gate enhances the security of the system since it requires very many trials by an intruder to succeed in breaking into the system.

(iv)The features of the system that are controlled by the firmware resident in the memory of the microcontrollers can be easily improved for future upgrade.

1.2                                             OBJECTIVE OF THE PROJECT

The main objective of this project is to develop an embedded system, which is used to verify and authenticate the authorized and person enter the room. This code is entered from a handheld unit. The security of the system is enhanced since the code is not easy to break and is only known to the operator.

1.3                                          SIGNIFICANCE OF THE PROJECT

• This project provides security
• Power consumption is less
• Used commonly available components
•  Project is simple and easy

1.4                                      APPLICATIONS OF OF THE PROJECT

·        This simple circuit can be used at residential places to ensure better safety.

• It can be used at organizations to ensure authorized access to highly secured places.
• With a slight modification this Project can be used to control the switching of loads through password.

1.5                                                 SCOPE OF THE PROJECT

The main component in the circuit is the controller. In this project 4×3 keypad is used to enter the password. The password which is entered is compared with the predefined password.

If the entered password is correct then the system opens the door by rotating door motor and displays the status of door on LCD. If the password is wrong then door is remain closed and displays “pwd is wrong” on LCD.

Main concept behind Radio Frequency Identification (RFID) based Security system is to allow the access only to uthorized persons . Rfid card has to be shown in front of the Rfid reader, then the access is allowed or denied to the resptive person/Rfid card.
