Self — Propelled safety system using CAN protocol — A review

The most of the people using vehicles which have become the most important part in our life for transportation. In existing system the main snags are glaring effect accidents due to opposite vehicle headlight illumination at night driving. Second the short circuit fault in automotive wiring. Third is to perceive gas leakage fire accidents. Fourth faults due to increase in temperature on engine. Fifth higher sound in horn which cause disturbance in restricted surroundings. Sixth inaccurate fuel level monitoring in analog meter. Seventh accidents due to unequal wheel pressure. The proposed system has two modules Master and Slave they are communicating through CAN (Controller Area Network). The hardware has been developed in SMT (Surface Mount Technology) with SMD (Surface Mount Device) components and the hardware uses double layer PCB (Printed Circuit Board) design to optimize the space requirement and power consumption. The proposed system will be in cost effective safety system, reliability and hardware size will be small.
