This document provides an overview of a vehicle tracking and locking system based on GPS and GSM technologies. The system puts the vehicle in sleep mode when handled by the owner and active mode when theft is detected. When theft occurs, the system sends an SMS to the microcontroller to stop the engine and lock the doors. The location of the vehicle can then be easily tracked. The system was implemented and tested successfully.

3. Introduction
 Vehicle tracking and locking system used to track the theft vehicle
by using GPS and GSM technology
 GPSGSM is the most important system, which integrate both
GPS and GSM technologies
 Vehicle tracking systems used in consumer vehicles as a theft
prevention and rescue device
 Vehicle tracking usually used in navy operators for navy
management functions

4. System overview
 Vehicle tracking and locking system used to track the theft vehicle
 Sleep mode / active mode
 If theft identified, IR sensor senses the signals and SMS is sent to
microcontroller, issue the necessary signals to stop the motor
 After switch off the engine, motor cannot restart without permission
of password
 Tracking of vehicle place is easy and doors locked automatically, thief
cannot get away from the car.

6. Analysis and Design
GPS TECHNOLOGY
GPS is a satellite-based navigation system consists of a network of
24 satellites located into orbit
The system provides essential information to military, civil and
commercial users
GPS works in any of the weather circumstances at anywhere in the
world

7. Cont..
A GPS receiver must be locked on to the signal of at least three
satellites to estimate 2D position and track movement
 Once the vehicle position has been determined, the GPS unit can
determine other information like, speed, distance to destination, time.
GPS receiver is used to detect the
vehicle location and provide the
information to responsible person
through GSM technology

8. GSM MODEM SIM300 V7.03
 It accepts a SIM card operates on a subscriber’s mobile number ,
just like a cellular phone
 It is a cell phone without display
 Modem sim300 is a triband GSM/GPRS engine that works on
EGSM900MHz, DCS1800MHz and PCS1900MHz frequencies
 GSM Modem is RS232-logic level compatible, i.e., it takes-3v to -
15v as logic high and +3v to +15 as logic low

9.  MAX232 is used to convert TTL into RS232 logic level converter
used between the microcontroller and the GSM board
 The signal at pin 11 of the microcontroller is sent to the GSM
modem through pin 11 of max232 this signal is received at pin2
(RX) of the GSM modem.
 The GSM modem transmits the signal from pin3 (TX) to the
microcontroller through MAX232, which is received at pin 10 of
IC1
Cont…

10. Features of GSM
 Single supply voltage 3.2v-4.5v
 Typical power consumption in SLEEP Mode: 2.5mA
 SIM300 tri-band
 MT,MO,CB, text and PDU mode,
SMS storage: SIM card
 Supported SIM Card :1.8V,3V

11. Debugging and Testing Process
 The debugging and testing of microcontroller-based systems
divided into two groups:
1] software-only tools
2] software-hardware tools
 The user program operated in a simulated environment where the
user can insert breakpoints
 Micro controller-based systems usually have interfaces to various
external devices

12. Cont…
 Inputs to the simulator come from files that store complex digital I/O
signals and waveforms
 Outputs is of the form of digital data or waveforms, usually stored in
a file, or displayed on a screen
 software program is written in c or assembly language and compiled
using Keil software
 The hex code of the program should be loaded into the AT89C52 by
using Top win Universal programmer.

13.  Hardware Assembling and Testing
 Assemble all the components on the PCB based on circuit diagram
 TX and RX pins of the GSM modem to pins 13 and 14 of MAX 232
and insert a valid SIM in the GSM modem
 Connect the GPS module according to circuit diagram
 This projects implemented and tested successfully by us
 This system is very useful and secure for car owners

14. CONCLUSION
vehicle tracking and locking systems used to track the theft
vehicle by using GPS and GSM technology. This system puts
into the sleeping mode vehicle handled by the owner or
authorized persons; otherwise goes to active mode. When the
theft identified, the responsible people send SMS to the micro
controller, then issue the control signals to stop the engine
motor. After that all the doors locked. To open the doors or to
restart the engine authorized person needs to enter the
passwords. In this method, easily track the vehicle place and
doors locked.
