INTRODUCTION

In today’s world there is a severe increase in the use of vehicles. Such heavy automobile usage has increased traffic and thus resulting in a rise in road accidents. This takes a toll on the property as well as causes human life loss because of unavailability of immediate preventive and safety facilities. Complete accident prevention is unavoidable but at least repercussions can be reduced. This embedded system can prevent the accident to occur and proper preventive measures are taken in this system. The ambulance service and the police station can easily find the location as the location along with the google map link was sent to their smart devices with mobile network accessibility.The system consists of eye blink sensor, temperature sensor, alcohol sensor, accelerometer, GPS module, GSM module, motor, buzzer, led etc. and all these devices are interfaced with the central micro controller unit. We are going to use eye blink sensor for detecting sleep by setting the certain time limit, if the driver gets sleepy,we can warn him. Temperature sensor helps us in detecting the heat of the engine and if the engine is overheated then that of a normal condition, we can warn the driver. Alcohol sensor helps us in detecting if the driver is drunk or not. If he/she is over drunk the vehicle provides warning and the engine stops functioning.Accelerometer detects the occurrence of accident and sends signal to the micro controller for further functioning. GPS module provides us the location, speed, time and date of the certain place where the vehicle is in the real time.If accident occurs, the location of accident that we get from the GPS is send to the ambulance service and police by the help of GSM module. Everything might be all right after a simple accident so the driver can re-inform the ambulance service and police station in this case.

MOTIVATION

Currently there is no technology for accident detection.As it is done manually there is loss of life in golden hours.The accident victim is dependent on the mercy of others to rush him to hospital.Many times an accident goes unnoticed for hours before help comes .Due to all these factors there is a high rate of mortality of the accident victims.In addition to this there is delay in the ambulance reaching the hospital to the traffic congestion between accident location and hospital which increases the chances of the death of victim

Although automobiles save our lots of travelling time, the risk increases in travelling because of the accidents. For the prevention from such accidents, we can use modern additional technologies. In the context of our project,we have used some sensors, electronic modules and microcontroller unit which helps us in providing prevention from accidents, detects the accident if it occurs even after the preventive measures and reports the ambulance service.

PROBLEMS

The use of vehicles increases in the proportion of the population. Due to the traffic
congestion, the accidents are also increasing day by day. This causes the loss of life due
to the delay in the arrival of ambulance to the accident spot or from the accident spot to
the hospital. So, it is necessary to take the accident victim to the hospital as soon as
possible. Whenever, the accident occurs, it has to be informed to the investigation unit.
So, it is also beneficial if the intimation is reached to the enquiry section so that the
time for the investigation can be minimized.

OBJECTIVES

The main objective of this project is to prevent the accident which happens due to alcoholism of driver, sudden asleep and due to the over heating of engine.Certainly, if the accident happens due to other cases, the used electronic devices will be able to provide the spontaneous message and exact location to police and ambulance in order to recover victims.
