CHAPTER ONE
INTRODUCTION
1.1 THE BACKGROUND OF THE PROJECT
It
was reported that as many as 1000 cars were stolen monthly in Nigeria
in the year 2000. The existing vehicle alarm systems are of no match to
the well-equipped thieves. In the United States, there are already many
transportation companies and vehicle manufacturers that employ Global
Positioning System (GPS) based location and tracking system combined
with conventional cellular communication for stolen vehicle recovery as
well as for constant monitoring of vehicle fleet management. However
there are situation where the GPS system cannot perform well such as at
underpasses and indoor parking. Most cars are still using he
conventional alarm system which is easily handled by car thief. One
major problem in those car alarms is tuning and adjustment. There may be
so many car alarms that are too sensitive, while the rest can withstand
a major earthquake without a single beep. Consequently, the public
loose interest in the car alarms since they could be falsely triggered.
Another weak point is that, it has limited capability to interact with
its owner. In addition, the conventional alarm systems did not provide
any means in assisting the recovery of stolen vehicle.
A car tracking
system is an electronic device that being installed in a vehicle to
demobilize and find the area where the vehicle is located by the use of
Global Positioning System (GPS) enabled phone and the signals from any
communication firm, but here we used MTN telecommunication service
provider.
With your GPS enabled phone you will call the phone number
of the phone that is attached to the car security device which will
indicate where or the position where the car is being demobilized for
recovery. It only indicates the position where the Network masts you are
using being installed.
TYPES OF CAR TRACKING SYSTEM
Car tracking
system can be categorized into various forms, namely passive and active
car tracking system. However what determines whether the system is
passive or active depends on the mode through which information can be
extracted from the system by the owner or the authorized user.

1:1:1 PASSIVE CAR TRACKING SYSTEM
A
passive car tracking device provides the records of journey activities,
which includes the destination and the speed used by the driver of the
car. This performs demobilizing and tracking but the difference is that
the active one gives a real time data while passive one can only bring
a report when the car reaches at a destination point for the owner to
be able to process out data recorded and stored in the memory of the
microcontroller. This system provides real time data transfer and makes
use of a GPS phone and signals from any network that have GPS masts to
carry out its tracking. Once the authorized person calls the number
assigned to GPS phone he/she will be able to get a real time data as
regards to where the car is as at that particular moment. For this
project, the installation deals with where and how the connections of
the car tracking device are made. The car tracking system which is
mainly the Global Positioning system phone working with signals from MTN
network is interconnected together with a relay which has an automatic
switching connected to a cable supplying mains to the fuel pump of the
car.

ABSRACT - [ Total Page(s): 1 ]Car security systems are still of no match to the well-equipped thieves. It is just a matter of seconds to break through the system. This project introduces and describes the design of mobile controlled car security system offering higher level of car security features. The mobile controlled car security is capable of providing an effective two-way communications between the alarm system and the car owner. This system is able to notify the car owner immediately when intrusion is detected. Additi ... Continue reading---
