Design And Construction Of A Car Timing Security System

ABSTRACT

This project work is titled design and construction car timing security system. Car timing security system is an electronic security device fitted to an automobile that prevents an intruder or unauthorized person from moving the car to a far distance. The system demobilizes the car after few seconds the car is moved.

The timing circuit that is connected with the ignition allows an intruder to start the car, which will later disconnect the ignition if the right code is not entered or the switch is not pressed, and the switch or code must be hidden which must be known only by the right user. Hence this has been achieved by the use of timing circuit and high current relay switches and it is powered by 12V dc car battery.

CHAPTER ONE

1.1                                                        INTRODUCTION

The rate of increase in car theft in this part of the world has reached an alarming rate. In the rave of this development, engineers in this country have been performing researches aimed at providing a lasting solution to this endemic act. This research team in an attempt to proffer a lasting solution thought of exploring the electronic car anti-theft device techniques as possible remedy.

The implementation is divided into two subsystems: the alarm and the car timing subsystems. The importance of this design cannot be over emphasized since it helps to reduce the rate of vehicle theft within our society.

For instance, when there is an intruder into the vehicle, the system will immediately and automatically stopped the car after few seconds the intruder moves the car thereby blowing an alarm the status of the car and preventing the car from being stolen.

This automobile security system is manually operated security system. Few of the many auto-motive theft-prevention systems allow a vehicle to start and temporarily run before disabling a critical component, such as the fuel or ignition system.

In case of hijacking, the driver can leave the car safely, and then use any phone to send out some commands and remotely cut off power or gasoline supply, so as to stop the car from running and get back the car easily. In such case, the vehicle snatcher will not be in a position to harm the vehicle owner.

Car security system has been very popular in recent times and widely used in most cars and automobiles owned by companies, business organizations and even by some private individuals who can afford the cost.

1.2                                                    AIM AND OBJECTIVE

The main aim and objective of the design and construction this project is to create a comfort in the minds of vehicle owners or users when their vehicles are parked or stationed anywhere without much fear of car-theft, by constructing a car timing security system which will deactivate the ignition if the right code is not entered (or is not entered correctly) or the switch is not pressed, and the switch or code must be hidden which must be known only by the right user.

1.3                                         SIGNIFICANCE OF THE PROJECT

• This device functions as an electronics watch dog. This device functions as a major security alarms used in an cars which can also be used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders.
• This system doesn’t require the car owner to activate it; it operates automatically. Car timing security system is considered as providing much more effective anti-theft protection than an audible alarm alone; many auto insurance companies offer lower rates for vehicles that are equipped with them.
• To determine whether there is a device in the car, it is very difficult. The alarm is intended to scare off intruders.
• The car timing security system is almost impossible to disconnect: to determine the location of the system unit from the first impossible, and the principle of operation of many of the hijackers is unknown.
• The simplicity and ease of use.
• High reliability and silent operation, which is important.

 1.4                                                 SCOPE OF THE PROJECT

A car timing security system is an anti-theft mechanism that prevents car from moving far unless the right deactivating code or switch is pressed. One of the advantages of car timing security system is that the car owner does not have to remember to activate it – its operation is automatic. The device is considered as a passive anti-theft system since it does not require action from a person to make it work. One disadvantage of the system is that car keys with the embedded transponder are more expensive and time consuming to replace if lost and usually requires a visit to a car dealer. Most new vehicles have a car timing security system as standard equipment, but aftermarket or add-on car timing security system are available for older cars or vehicles without factory-installed car timing security system.

1.5                                           LIMITATION OF THE PROJECT

• For the device to work, the owner must put ON the ignition
• Car keys with the embedded transponder are more expensive and time consuming to replace if lost and usually requires a visit to a car dealer.
• The system can cause accident if not de-activated in time.
• The alarm could cause noise pollution.
