Accident Detection System and Vehicle Overtaking

System Using Wireless Technology

Synopsis :-

Introduction(Abstract) :-Accidents are one of the most dreaded situations in one life, on an average

atleast one vehicular accident occur everyday around the world. It has also been

observed that the most number of people die as they do not get to the hospital intime after such road accidents in highways or remote locations such as rural

villages. This causes unintended loss of life.

Therefore to overcome such haphazards we propose to development awireless system which will reduce this problem drastically. The system will relay

wirelessly to a local police stations or hospitals, the exact location of an accident

as it occurs. Therefore notifying the authorities about such an event , where theycan help out the accident victims in time. Thus saving precious lives.

The system/ device will consist of micro controllers, wireless communication

modules and display devices to enhance user interaction and to make it easy for

anyone to use.The other benefit from this system is that it is also being used as a driver

assistor for overtaking vehicles in highways. Which will reduce noise pollution

and unwanted honking of horns? Therefore this project is designed to enhance theutility of electronics and telecommunication devices to enhance and save human

life on the go.

Market Survey :-

After a long hectic market survey at various electronic

component manufacturers; we found that even though costly, every necessarycomponent required for this project was available in the market. Also after a

proper search we concluded that although such a project has already been

invented, it is hardly a ready application anywhere.

Features :-

1. User friendly as it has GUI.2. Its an intelligent system as it consist microcontrollers.

3. Unique communication protocols and frequencies.4. The comm. module uses frequencies that are free in India.

Block Diagram :-

Block Diagram explanation:-

Accident Detection System : This is basically a mechanism which will notify themicrocontroller that an accident has occurred in the vehicle. This system is just

switching mechanism which has very less response time.

MICROCONTROLLER : This block consists of microcontroller ATmega8AVR based circuit. Here microcontroller is used as the main digital signal

processing system. It will control the communication module and the LCD

display.

Communication Module : This block consists of a 433Mhz ASK

transmitter/receiver module. This module has the capability to communicate the

Micro

ControllerDevice.

distance of over 10 mts with very less power. As it comes in a SMD package, it

also is small in size and consumes very less standby power.

LCD Display : This block consists of a standard 16x2 alpha numeric lcd display,

which also consumes very less power. This device is directly interfaced and run

by the micro controller.

Power Supply: This block consists of a regulated dc power supply. Usually a

battery in series with a 7805 ic regulator is used to supply 5V dc voltage.

Component Details : -

The list of components used in this project is given asfollows: - 1) Micro controller

2) Communication module

3) LCD display

4) Switches5) 7805 regulator

6) Resistors and capacitors.

Of all the components listed above, microcontroller card or IC is the heart

of the circuit and its cost is high as well. The costliest part of this circuit is the

communication module on which this particular project is to be implemented.

Advantages and Disadvantages :-

ADVANTAGES :

1) This system reduces accident deaths drastically.

2) Easy to implement and user friendly.3) Reduces Noise pollution.

4) Cheap and maintenance free.

DISADVANTAGES :

1) Communication modules are not directional.

2) Range of communication is only 10mts.

Applications :-

Since this project is designed and optimized to a specific application, its

applications are limited, other than its intension. Its can be modified into severalother systems also.

Future scopes :-

There is a vast range of future scopes for this projects. It

can be enhanced with GPS for better communication.
