Embedded Automobile Engine Locking System Using GSM & GPS Technology

This paper deals with the design &development of an embedded system, which is being used to prevent/control the theft of a vehicle. The developed instrument is an embeded system based on GSM technology. Here, we have made an attempt to develop an instrument based on At mega 8 microcontroller and operated using GSM technology. The device is a simple and low cost vehicle theft control embedded system. The entire system is installed in the engine along with GSM Modem. When the owner of the automobile finds that the automobile is missing, a SMS can be send by his/her mobile which is authenticated by device to stop & lock the engine of the automobile The information is passed onto the central processing insurance system which is in the form of the SMS, the microcontroller unit reads the SMS and sends it to the Global Positioning System (GPS) module using the triangulation method. GPS module feeds the exact location in the form of latitude and longitude to the user's mobile. By reading the signals received by the mobile, one can control the ignition of the engine; say to lock it or to stop the engine. The main concept in this designis introducing the mobile communications in to the embedded system. The entire designed unit is on asi ngleboard.
