PROJECT : REAL-TIME VEHICLE LOCKING AND TRACKING SYSTEM

USING GSM AND GPS TECHNOLOGY-AN ANTI-THEFT SYSTEM.

ABSTRACT :

The safety of private and public vehicles is a major concern nowadays so having GPS vehicle tracking system ensure their safety while travelling. This vehicle tracking system can be found in consumers vehicles as a theft prevention and retrieval device.This Project presents an automotive localization

system using GPS and GSM-SMS services. The system permits localization of the

automobile and transmitting the position to the owner on his mobile phone as a short

message (SMS) at his request. The system can be interconnected with the car alarm

system and alert the owner on his mobile phone. This tracking system is composed of a

GPS receiver, Microcontroller and a GSM Modem. GPS Receiver gets the location

information from satellites in the form of latitude and longitude.

The Microcontroller processes this information and this processed information is sent to

the user/owner using GSM modem. Microcontroller also gets the speed of the vehicle and

sends it to user/owner. The presented application is a low cost solution for automobile

position and status, very useful in case of car theft situations, for monitoring adolescent

drivers by their parents as well as in car tracking system applications. The proposed

solution can be used in other types of application, where the information needed is

requested rarely and at irregular period of time (when requested). This system is also can

be interfaced with Vehicle airbag system. This enable it to monitor the accident situations

and it can immediately alerts the police/ambulance service with the location of accident.

This project uses regulated 5V, 750mA power supply, 7805 three terminal voltage

regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify

the ac output of secondary of 230/12V step down transformer.
