Vehicle Security System using Embedded and GSM Technology

Abstract

This paper deals with design and development of the theft control system for an automobile, which is being used to prevent or control the theft. The developed system makes use of an embedded system based on GSM technology. The designed and developed is installed in the vehicle. An interfacing mobile is also connected to the microcontroller which is in turn, connected to the engine. We need to give the password before starting it. Once an unauthorized person tries to run the vehicle by giving a wrong password an alert message is sent to the owner of the vehicle that the vehicle is being stolen. This information is passed on to the central processing system whereby sitting at a remote place, a particular number is dialed by them to the interfacing mobile that is with the hardware kit which is installed in the vehicle. By reading the signals received by the mobile, one can control the ignition of the engine, say to stop the engine immediately. Again it will come to the normal condition only after entering a secured password. The owner of the vehicle and the central processing system will know this secured password. The main concept in this design is introducing the mobile communication into the embedded system. The designed unit is very simple and low cost. The entire designed unit is on a single chip. When the vehicle is stolen, the owner of the vehicle may inform to the central processing system, then they will stop the vehicle, by just giving a ring to the secret number and with the help of SIM tracking knows the location of the vehicle and informs to the local police or stops it from further movement.
