GSM Based Anti-theft System for Automobiles

Abstract

Car theft cases are higher than ever, an excellent protection can be provided with reliable anti-theft system. Car central locking system ensures the best guarantee to protect your car from different kinds of theft cases. It is a car security device that offers excellent protection to car. A car with central locking security system helps the user to lock and unlock doors at the press of a button. Again this system could not prove to provide complete security and accessibility of the vehicle in case of theft. So a more developed system makes use of an embedded system based on GSM technology. The designed & developed system is installed in the vehicle. The main concept in this design is introducing the mobile communications into the embedded system. A vehicle tracking system combines the installation of an electronic device in a vehicle with purpose-designed computer software to enable the owner to track the vehicle's location, collecting data in the process. Modern vehicle tracking systems commonly use Global Positioning System (GPS) technology for locating the vehicle. Vehicle information can be viewed on electronic maps via the Internet or specialized software. To avoid this kind of steal we are going to implement a system it provides more security to the vehicle. The RF transmitter is attached with the vehicle which has its own identification. This data will be continuously transmitted to the receiver connected to the microcontroller. This GPS will be locating the position of vehicle and transmit that data to the microcontroller. Suppose the RF receiver is not receiving signal from the transmitting unit, receiver unit send the signal to the microcontroller, from that we can identify the theft. If the vehicle is stolen, it automatically sends location of the vehicle to its owner as a SMS through GSM modem. This is a much simpler and low cost technique compared to others.
