Real Time Embedded System for Accident Prevention

This Paper presents automatic accident prevention with security enable technique, speed control and accident detection system. .The main objective is to design an Renasis RL-78 controller to monitor the zones, which can run on an embedded system and to automatically locate the site of accident and alert concerned people. It should be done automatically as the person involved in the accident may not be in the position to send the information [7].The proposed system is composed of two separate design units: transmitter unit and receiver unit .Just before the vehicle to enter the transmitter zone, the vehicle speed is controlled by receiving the signal from the RF transmitter. For this, RF transmitter can be kept at a few meters before the zone, where the speed has to be controlled such as school zone, hospital zone etc. Security system includes alcohol sensor and seatbelt sensor (only for car). Accident detection system consists of GPS and GSM in cell phones [12].As accident occurs, accident switch will go high and sends the signal to the Renasis Rl-78 controller[ 6].Then, the GPS available in the smart phone will start communicate with the satellite and get the latitude and longitude values and name of place of accident will be send to the previously set phone numbers of relatives and concerned authority [5].
