CHAPTER ONE
INTRODUCTION
1.1 Concept of Study
Over the
past years, automobile manufacturers have been integrating all manner of
security system, to its automobile, so as to ensure that users are
provided with all the security needed to ensure the safety of the
vehicle. Considering the lifestyle of most users, the companies realize
that its customers are always busy and most times have little or no
information about lifestyle beyond their work place. Also from their
search it was found that a large percentage of vehicle users use cell
phones as their primary means of staying in contact with their family,
friends and offices, (Joann Muller (2005-11-28,).This led to the idea of
developing a system that allows drivers and vehicle owners to stay in
constant communication with the world outside their automobile.
Since
the concept of security has become a major concern for our world, and
to most vehicle users, automobile manufacturers employed the idea of
vehicle security system which do not just help the human agent but could
on their own completely provide all the necessary security requirements
without supervision.
An Automobile Security System (ASS) as a form
of a vehicle security system combines the installation of an electronic
device in a vehicle, or fleet of vehicles with purpose-designed computer
software to enable the owner to track the vehicle’s location while
collecting data in the process. In this kind of security system, a
telecommunication system and method is used for instructing a device
interfaced with a vehicle’s electrical system to activate or deactivate
specific electrical device such as the ignition, car lock system and the
electronic fuel injector using a cellular network. This can be
accomplished by utilizing a mobile terminal or a unit containing the
mobile terminal receiver, herein after referred to as a “GSM MODEM†or
“Radio Interface Unit†(RIU), which is interconnected to a “Power
Interface Unit†(PIU).
The PIU directly interconnects to the
vehicle’s electrical system and ignition. This system enables the
vehicle user to access their vehicle’s electrical system from remote
places simply by dialing the cellular phone number (a number associated
with the RIU/GSM MODEM) from another mobile phone. The RIU when
triggered will either send notifications via SMS or call to the vehicle
user or receive instructions from the same user to activate or
deactivate electrical devices depending on the nature of instruction
given by the user.
With ASS the user can perform functions such as
locking the doors, switching off ignition, monitoring temperature,
turning on light, cutting off the electronic fuel injector and having
different reactions for several situations.
1.2 CLASSIFICATION OF AN AUTOMOBILE SECURITY SYSTEM (ASS)
There
can be many differentiating factors used to classify Automobile
Security Systems but in this work, we will classify them under two
major headings;
· Intelligent systems.
· Non-intelligent systems.
We could simplify it further as microcomputer based and non-microcomputer based security systems.
intelligent
systems: These are security systems that have an intelligent device,
which monitor the space area or variable under guard, and provide a
response signal when there is a bridge in normalcy. These systems are
made up digital devices like the microprocessors and microcontrollers
and posses a level of intelligence by which they measure the variables
under guard. They can also be completely un-manned or partially
un-manned. In the design of these systems, sensors and transducers
become a major part of the circuitry. Sensors and transducers are the
actual components that work with the processor to achieve a fully
automated system.
Non-Intelligent Systems: Non-intelligent systems
are systems that do not have any processor in their circuitry. This
ranges from the manual crude method that employs human effort and the
manually run machines that aid the individual to the monitored cameras
and laser monitoring intruder devices which blare alarms.

ABSRACT - [ Total Page(s): 1 ]The purpose of this project is to design and construct a car tracker system with code using GSM. A good car attracts everyone including thieves. When it comes to the safety of cars, car owners should be very careful. These days, the market is flooded with many safety devices. Typically, the most successful ones among all is the ‘alarming device’. Car alarms are good but they cannot give 100% satisfaction. Smart thieves know how to dismount the smartest car alarm security systems in ... Continue reading---
