automobile thefts and the vehicle production
are increasing in yearly world. Thefting the vehicle is a common problem.
The owners of the
vehicle have take care of thefting the vehicle. The motivation of this paper is
to avoid the thefting of vehicle and deduction of vehicles. When the vehicles
are theft the GSM will send messages.The owner will receive the message of their own vehicle.
The owner is now
responsible for sending the message back in effect off thefting the vehicle.
For this reason
when any person is stealing the vehicle the modem in the GSM will send a
message through the microcontroller which will interrupt the vehicle.
On seeing the
message the microcontroller will stop the vehicle.
Keywords: GSM modem, voltage regulation, micro controller.
everyone in this world prefers to make
the things easy perfect to handle, this project sets an example to some extent.
In this paper we deal with the security of the vehicle. Whenever the GSM modem
receives the message from the particular mobile then the car engine gets
stopped. The message received from the mobile number send to the vehicles
owners mobile number.. Applications such as the air-conditioner, VCD player,
DVD player, printer, fax machine, mobile phone etc. are examples of embedded
systems. Each of these appliances will have a processor and special hardware to
meet the specific requirement of the application along with the embedded
software that is executed by the processor for meeting that specific
requirement. The embedded software is also called “firm ware”. The
desktop/laptop computer is a general purpose computer.
2. Proposed Method
are using the
manufacturer security alarm only. The thief had an experience
regarding this security alarm, which means their work
is getting easier to steal
the car because they had
well known about the alarm circuit. They know when the time to cut off the alarm and had well known about the system. So, it is important to
double protect the security of the vehicle. Antitheft security
system utilizes an embedded system design with
Dual Tone Multi Frequency
(DTMF) and a GSM to
monitor and safeguard a vehicle. It secures the vehicle
against theft. Upon activation, it automatically demobilizes the vehicle by
disconnecting the ignition key supply . This makes impossible
for anybody for starting the vehicle in a moving time. In an attempt of
theft through the vehicle doors
or boot, the system
sends text message to the vehicle owner and at the same time starts up
an alarm. This design popped out due
to the increasing
rate at which
packed vehicles are
stolen especially in our country, but with this design this packed
vehicle is being monitor red irrespective of where it is packed, provided
there is GSM network coverage. Now GSM will not send message to
the vehicle and we only we can hear the
alarm from the security . Then it is guaranteed that the vehicle will send
text message to his phone, and at
the same time, have people around alerted of what is happening.
automobile thefts are increasing and also the production of vehicle.
The theft detection system of a vehicle using GSM is as shown in the Fig.1 and 2.

systems using a digital technology will become
the universal method of tele-communications.
Short message service is a technique of
delivery of small messages over the mobile networks. It is a store and forward
way of transmitting messages to and from mobiles. The message (text only) from
the sending mobile is stored in a central short message center (SMS) which then
forwards it to the destination mobile. This means that in the case that the
recipient is not available, the short message is stored and can be sent later.Since
signaling message system used signaling to desired channel as opposed to dedicated
channels, these messages can be sent/received simultaneously with the voice/data/fax through GSM network. SMS supports national
and international roaming. This means that you can send short messages to any
other GSM mobile user around the world. With the PCS networks based on all the
three technologies, GSM, CDMA and TDMA supporting SMS, SMS is more or less a
universal mobile data service.

system installed in the engine of the vehicle along with the
GSM modem. By entering a correct password the instrument allows to activate the
12v relay and then ignition of the engine will start. Hence starts the vehicle. If anyone
tries to access the vehicles
password or theft the vehicle , then
the MCU will block the entry of further password. Then the buzzer will turned on to create a noise to panic the culprit, followed by sending a message “Alert: Car Is Under
Threat” through GSM modem to the owner’s mobile for further action for prevention of his vehicle. According to the prototype
model after entering correct password the Fan
will move and at the same time, according to the instruction it
will run forward for 10 sec and backward for10 sec like
an automobile. Password can be c hanged by the following proper procedure. First
enter # , then enter the old password , then new password. Now test, whether the new
is working or not. As per algorithm given below the new password will retain even after power failure.
So it will work as usual. The source code is written in the embedded C language. To develop the
source code the flow chart of the project is shown in the figure below 3.

control system by using GSM
3. RESULTS AND DISCUSSIONS
This GSM based vehicle theft control system retrieves vehicle status is whether
it is in theft
mode. This data is
fed to the microcontroller, which is interfaced to a GSM modem. The microcontroller generates the
vibrations and sends an SMS to
the concerned authority over GSM modem on
periodical interv alls which is set by the user.
An LCD display is connected to the
microcontroller for crossing the data received before being
sent over GSM. This project will be very
useful to people to
keep track of their vehicles. Further,
this project can be developed by making an arrangement
to stop the ignition of the vehicle by the owner remotely by sending an SMS in theft
consists of an ARM
Controller, Relay circuit, GSM Module and LCD
Display are interfaced
on a single board
and embedded on single board which is
embedded to a
vehicle as a control unit. The relay is connected to the
Vehicle Engine Unit of the Automobile When “OFF” message sent by the
owner of the vehicle to the mobile embedded in the control unit, the controller displays
the message in the
LCD as shown in the Fig.4.and invokes
the relay that is connected to engine of the vehicle stop the
flow of fuel by making the engine to be locked.
Engine OFF Message
Similarly when “ON” the owner of the vehicle will send a message to the
mobile embedded in the
control unit, the controller displays
the message in the LCD is shown in the Fig.5 and allows the fuel flow
by unlocking the vehicle engine.
Fig.5 Engine ON Message
In this paper we
have studied and implemented a complete working model using a Microcontroller.
Using this project, one can control his vehicle’s car engine by means of an
SMS. The main purpose of this paper is
to prevent vehicle theft. This functionality is achieved by detecting vehicle
status in theft mode and by sending an sms which is generated automatically.
This sms is then sent to the owner of the vehicle .The owner can then sent back
the sms in order to disable the ignition of the vehicle.
Thus in this way
crimes can be reduced to a great extent as vehicles today are being stolen in
large number. Hence, vehicles today require high security which can be achieved
with the help of this application.
5 Future scope
enhancement can be done to this paper by
using a GPS
system that helps to find
out the exact position of the vehicle with the help of its latitude and longitude which then can be sent to the owner of the vehicle via SMS. This data can be then entered by the owner on Google
map to find out the
exact location of the vehicle. There are many Applications of GPS based Vehicle theft
detection system using GSM technology, few
of them are
listed below:GPS Car theft detection can be used in
transportation vehicles of Companies, schools, colleges and industries. This
work can be used in our cars
and even in bikes.
