Real time embedded system for accident prevention

This paper presents autonomous accident prevention with security enabling techniques, speed control and accident detection system. The main objective is to design an Atmega328P 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 a circumstance to send the information [7]. The proposed system is composed of two separate design units: transmitter unit and receiver unit. Just before the vehicle is in 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. Security system includes alcohol sensor, eye sensor and smoke sensor. Accident detection system comprises of GPS and GSM in cell phones [13]. As collision occurs, piezoelectric sensor will detect the signal and sends it to ATmega328P microcontroller [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, ambulance services etc [5].
