Embedded Automobile Based Vehicular Security System

摘要

Electronics embedded systems have become an essential and integral part of modern vehicles. This paper deals with the design and development of an embedded system, which shall be programmed to prevent/control the theft of a vehicle. The developed instrument is a basic embedded system based on Bluetooth and fingerprint technology. The first module is placed in the engine of the vehicle and the other module is placed on the dash of the vehicle, both the MCU's are interfaced with a bluetooth module. The ignition relay of the vehicle can be programmed in such a way that it responds to commands/fingerprint received from the transmitter MCU only. The Bluetooth transmitter is identified by the MCU using the hardware address which is unique for each transmitter. In addition to the above features, an extra feature of facial recognition can also be introduced to ascertain more security of the vehicle.
