This project is very helpful for claiming against the accident. With the help of this project we can able to record and generate the report in various formats.

Key Words: Event, Multiplexer, Retrieve, Investigation, Detect, etc..

  1. INTRODUCTION

    As we all familiar about the current situation in road accidents, but still we dont know the exact reason behind that accident. So in such conditions this Event Data Recorder (EDR) plays very important role, in such situations this device activates the car's airbags also record and store information of a car's speed whether the driver of car fastened seatbelts or not, and whether driver hit the brake before a collision. This device works like a black box in airplanes. EDR can record the Car's Speed, status of seat belt, brakes and the video recording of that moment. Now days it is very helpful device for insurance companies as well as for police for further procedure. In this project various sensors are interfaced with the microcontroller for recording various parameters of the accident so that it can be used to analyse the accident accordingly.

    The four wheeler accident is a major problem in many countries. Despite awareness campaign, accidents are increasing due to rider's poor behaviours such as speed driving, driving with alcohol consuming, riding with insufficient sleep, etc. Deaths and disabilities numbers are very high due to late medical assistance to people who got in accident. This result into huge social and economic burdens to people involved. By considering the importance of the problem, many organisations and automobile industries have developed safety devices to protect peoples from accidental injuries.

    In this the device contains two lights for knowing its present status such as a green indicator light means the system is armed and ready to capture an event. And red light represents that when collision of vehicle take place it turns on and start recording the data related to accident during a pre-defined period before and after the impact. This recorded information is stored in the internal memory of the device and we can take this data on our external memory. To save the internal storage of the system and to increase the efficiency, system will get refreshed after every start of the vehicle, unless an accident has taken place.

    This paper mainly contains two sections. The first one is how to detect and collect the information from the vehicle. The second is how to present the data to the user in a simplified way. For implementing first section various sensors are used and for second one by writing

    records the data and second is it retrieves the data from microcontroller memory to display on LCD. Mostly following sensors data that is needed after the accident: Belt status, Break status, Speed Status, Vibration status etc.
