The document describes the design of an advanced car security system using RFID, GSM, and an Arduino board. The system is intended to prevent car theft by only allowing an authorized RFID card to start the car. If an unauthorized card is used, the system will send a call to the owner's phone using GSM and stop the car once the owner responds. The document outlines the components, design, block diagram, and results of testing the system. It concludes that the system enhances car security while allowing for authorized access.

3. PROBLEM ANALYSIS AND
SOLUTION
 Motor vehicle theft is the biggest concerned these days.
 The statistics shows, the theft has increased on the large scale and industry
observers caution that thieves constantly devise new and sophisticated
means of stealing vehicles.
 Thus, the project is aid in providing the security to the car by bringing an
electronic module called “Advanced Car Security”.

4. Introduction
But Don’t Worry
There are various methods of prevention to
reduce the likelihood of a vehicle getting
stolen.
 From the LITERATURE SURVEY Motor
vehicle theft is the criminal act of
attempting to steal a car.
 There were an estimated 1.2 million motor
vehicle thefts, or approximately 416.7
motor vehicles stolen for every 100,000
inhabitants.

GSM module
LCD
display

6. Continue…
 Initially the LCD displays “RFID card please.” the system analyse
the code of the RFID card and allows the access only if the card code
matches the pre-defined code in the module.
 After checking of the card, LCD display “card ok and allow” which
assures that the driver of the car is the owner.
 In case someone tries to start the car without RFID check or with a
wrong RFID card the system will inform the owner of the car by
sending a call to him/her at the registered cell phone number using
GSM and stop the car as soon as the owner sends the
acknowledgement by calling.

7. Concept of project
 Flow of project:
Stage 1: Detection of RFID tag
Stage 2: Display whether access is granted or not
Stage 3: Owner can start the car if the access is granted
Stage 4: Send the call via GSM if access is not permissible
Stage 5: Receive the acknowledgement from the owner to stop the car and
stop it.

10.  The Mega 2560 board has a number of facilities for communicating with a
computer, another board, or other microcontrollers.
 The ATmega2560 provides four hardware UARTs for TTL (5V) serial
communication. An ATmega16U2 on the board channels one of these over
USB and provides a virtual com port to software on the computer Windows
machines will need a .inf file, but OSX and Linux machines will recognize
the board as a COM port automatically.
 The Arduino Software (IDE) includes a serial monitor which allows simple
textual data to be sent to and from the board. The RX and TX LEDs on the
board will flash when data is being transmitted via the
ATmega8U2/ATmega16U2 chip and USB connection to the computer

12. Continue..
 RFID stands for Radio-Frequency Identification.
 The RFID device serves the same purpose as a bar code or a magnetic strip
on the back of a credit card or ATM card.
 A Radio-Frequency Identification system has three parts:
- A scanning antenna
- A transceiver with a decoder to interpret the data
- A transponder - the RFID tag - that has been programmed with information.
 RFID Tag: -
An RFID tag is a microchip combined with
an antenna in a compact package; the packaging is
structured to allow the RFID tag to be attached to an
object to be tracked. RFID tag has diverse range of
functions

14.  Description
 The GSM shield by Arduino is used to send/ receive messages and
make/receive calls just like a mobile phone by using a SIM card by a
network provider.
 Advantage of using this modem will be that its RS232 port can be used to
communicate and develop embedded applications.
 The modem can either be connected to PC serial port directly or with any
microcontroller through MAX232.
 This GSM modem is a highly flexible plug and play quad band SIM900A
GSM modem for direct and easy integration to RS232 applications. It
Supports features like Voice, SMS, Data/Fax, GPRS and integrated TCP/IP
stack.

15.  Liquid crystal Display
LCD displays consists primarily of two sheets of polarized glass plates with a
thin layer of liquid crystal solution sandwiched between them.

16.  Car Module
I. Relay
What is relay?
 Usually a relay is used in a circuit as a magnetic switch to turn on a
second circuit.
 A relay is an electromagnetic switch, which is activated when a
small current is passed through its coil.
The interesting fact is that this small current is capable of turning on a
secondary circuit which works on much larger current.
05/15/16 16Advanced car security system

17. Why relays are useful to us?
 As the name indicates, many sensors are extremely sensitive type of
electronic components and produce only small output currents.
 But we need to drive bigger electrical machines using those sensors!
Relays, makes it possible for small currents to trigger bigger current
circuits.

18. II. Servo motor
What is servo motor?
 Servos are motors that are used to accurately
control physical movement. This is because they
generally move to a position instead of
continuously rotating.
 They are ideal for making something rotate over a
range of 0 to 180 degrees.
05/15/16 18Advanced car security system

19. How servo can use?
 Specifically, in our circuit, we will make it so that the servo motor rotates
180 degrees and then stops and then rotates 180 degrees back (in the
direction it began).
 Servos are easy to connect to the arduino and control, because the motor
driver is built into the servo. This means that the driver circuit to operate
the motor is internally constructed into the servo.
 Thus, all we do is connect the pins of the servo directly to the arduino board
and program it, and that's all that needs to be done.
 The different pin terminals are differentiated on the servo motor by their
colors.

Black Wire GND terminal
Orange Wire digital pin (I/O)

22. Limitations
 If wrong RFID is scanned the owner gets a call on the registered
number and if the owner sends an acknowledgment to stop the car
the car may stop half the way in the middle of the road which may
increase the probability of the accident which is not at all likely for
the owner.
 After the car stops, the thief may run away and thus, the owner may not
come to know about the thieves which is again not in favour of the owner
05/15/16 22Advanced car security system

23. Future Scope
 Smoke emitter can be introduced in the module which can overcome
the limitation of car accident that is when the owner sends the
acknowledgment to stop the car, the switch of the smoke emitter
circuit triggers and the car becomes smoky so the driver due to his
vague vision takes the car at the off side of the road and then the car
stops gradually.
 A hidden camera can be placed in the car which can capture the
image of the thief and help the owner to find the thief.
 GPS can be added in the module by which we can trace and monitor
the location of the car and can find stolen car easily via location.

24. Conclusion
 Thus advanced car security enhances the security of a vehicle and
makes it possible only for some selected people to access the car.
Thus by implementing this relatively cheap and easily available
system on a car one can ensure much greater security and
exclusivity than that offered by a conventional lock and key.
 There is a scope of further improvement in terms of efficiency and
accuracy which can be achieved by improving the hardware to
capture the image or by improving the image enhancement
techniques
 The project “Advanced Car Security” has been successfully designed
and tested. Integrated features of all the hardware components used
have developed it.
