    ABSTRACT

    This project deals with the design and implementation of a radio controlled car lock with 5-minutes ignition deactivation facility capable of locking a vehicle using a remote control from a distance. The system is designed in two functional units; the transmitter which is an RF handheld remote control, and the receiver units. The receiver unit is realized in several modules. A tuned radio frequency receiver (TRF) output is used to trigger a bistable multivibrator configured using CD 4013 whose output is used to trigger the car lock switch.

    The four doors of a conventional car are represented using four push and hold switches wired to trigger a 5-min delay circuit realized with Ne555 timer in monostable mode. The system works in such a way that if your car is snatched at gunpoint, you simply press the remote and the car locks by switching off a green LED before the armed robber zoom off. And once any of the doors is opened and closed, the vehicle automatically comes to a stop after five minutes. And the ignition lamp goes off too. The system also contains a reset switch installed at a recessed location in the car for resetting the locking system when the car is found. Due mainly because of the area of application, the system is chordless.


    Design and Implementation of a Radio Controlled Car Lock with 5-Min Ignition Deactivation Facility

    CHAPTER ONE

    Radio Controlled Car Lock System Overview

    1.1. Background of the Study

    The present innovations relate generally to wireless transmitters and more particularly to remotely controlled operations which employ RF transmitters and Receivers. With the invention of GPRS, GPS, 3G, 4G, GSM and the internet people in different parts of the world can communicate and control some operation effectively. Putting into consideration the above milestone, there is vital need to incapacitate car thieves using a wireless technology. Because of this, a thorough research was embarked on Remote control car lock with 5-minutes ignition deactivation facilities. This system prevents car snatchers from disappearing with the vehicle. It frustrate them five minutes after closing of any of the car doors. It arrests the issue of car snatching and deactivation in real time, without any delay. It is made up of a portable handheld RF remote control which should always be in the driver's pocket. And the receiver is installed inside the vehicle.

    1.2. Problem Statement

    Owing to the high rate of unemployment in the country social vices have been on the increase. This menace has called for individual security of lives and properties. All over the world, car lifting is a threatening social vice people have lost their vehicles, worth of billions of dollar, to car thieves and sometimes their lives. These is utmost need to come-up with a means of tracking car thieves by demobilizing the vehicle irrespective of their location using wireless technology regarding the harms that have been caused by car lifting/ thieves, I deemed it necessary to embark on the project design and implementation of a radio controlled car lock with 5 minutes ignition deactivation facilities. This system should be able to lock the vehicles ignition system and deactivated it/brings the car to a stop, 5-minustes after closing and of the doors. This device should use a radio frequency (Rf) technology.

    1.3. Aims and Objectives of the Study

    1. The aim of this project is to design and implement a radio controlled car lock with 5-min ignition deactivation facility capable of discontinuing the movement/motion of a vehicle snatched at Gunpoint using remote control.
    2. The objectives of this study are; to develop a prototype system that can be used to lock and deactivate an automobile snatched at gunpoint using RF remote control.
    3. To develop an automotive device which can be powered using car battery.
    4. To develop a system which can use Rf remote to lock a vehicle.
    5. To develop a module which can switch the ignition of vehicle using the car doors

    1.4. Significance of the Project

    This project work signifies a lot in computer, electrical and electronic engineering. It is used in deactivating vehicles a snatched at gunpoint, also has many relevance in telecom. A project of this nature will be very vital in security/surveillance. This design can be modified to function as an RF remote controlled electronic appliance — this will make it have ground in domestic and industrial settings. The project can be used in office and home locks. This device, if funded and developed, will sell like a German burger.

    1.5. Specification

    This project work is a prototype of the real — life system which would be used in a vehicle. This device would be able to lock the car ignition system by pressing an Rf remote control at a maximum range of 100 meters. This system would be able to deactivate the ignition system of the vehicle after a period of 5 minutes any of the doors is opened and closed. This device can only lock and deactivate the vehicle but cannot indicate or show the location of the vehicle. It only makes the car thieves stranded.

    Defense Procedure for Computer Science Researchers

    In preparation for defending a project or seminar on Design and Implementation of a Radio Controlled Car Lock with 5-Min Ignition Deactivation Facility, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

    Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

    Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

    During the question and answer segment, the External Examiner may pose questions pertaining to your research.
