ACCIDENTAL ALERT & RESCUE SYSTEM

Group - 33

Problem Definition

Accidents happen everywhere, every day to even the most careful drivers.

Most of the people who met with accidents die because of delay in providing help at right time.

Our main objective is to reduce the accidents and rescue the injured people who met with accident.

Case 1:- (No Accident)Vr =0 and Current normally flows in the circuit.

Case 2:- ( Accident)Vr =0 and flow of current reduced in great amount and this is detected by Microcontroller

Concept 4(Rubber Tube Mechanism)

Concept Selected(Accelerometer Method)

An accelerometer is a sensor that measures the physical acceleration experienced by an object due to inertial forces or due to mechanical excitation.

By employing this method, we can find accurate details of the accident happened or not and also the exact location of the accident.

In this mechanism , the vehicle design may not be changed much and in turn reusability power is more.

Low cost and High serviceability makes this concept a best among other concepts.

How our system actually works ?

Functions to be Implemented in Design

Detection of accident by a device and sending it to microcontroller. Activating the GPS to access the co-ordinates of the accident and then

sending them to microcontroller. Conversion of co-ordinates into a form of message by microcontroller. Sending this message to the family members ,police station, hospital

via sms or voice message through a GSM modem.

Reducing accidents by giving accident alerts to the driver from alcohol detection and collision detection

If accident has happened then process is:-

Design Brief Benefits:-

a) Helping injured at a right time of an accident. b) Used also as a tracking device.

c) Reducing traffic issues (some part). d) Alcoholic detection e) Collision Detection

Drawbacks:-a) Failure incase of “Network Less” area.b) Failure incase of heavy accident happening to the

vehicle.

CONCLUSION

At present, there is no system like automatic detection of accident and sending the location of accident.

Also, there is no simple mechanism like us to detect alcoholic consumption and collision alert.

Though there are some minor disadvantages, it is more useful in present day busy system of human.

The system that is shown can be compressed into a form of a “SMART PHONE” which can be run by creating an application(apk file) because smart phone already has ACCELEROMETER , GPS, GSM inside it.
