INTRODUCTION:
What do you do if you are injured or trapped in the vehicle
The communication says not only that something has happened but also how serious the accident
NEED TO REDUCE THE ACCIDENT RESPONSE TIME
Most of the fatalities occur soon after the accident. Statistics says that 30 percent of deaths occur within minutes of the crash.
It also reduces severity of survivors' injuries
HARDWARES REQUIRED
Tri-axial accelerometer
Seat weight sensors
Safety belt sensors
Air bag sensors
GPS receiver
CMOS camera
Flash memory
On-board microprocessor
Onboard communications
Cellular phone
PRINCIPLE:
By pushing a button in the car, the call to the emergency centre can also be made manually.
WORKING:
The message sent within the emergency call contains a minimum data set (MDS).
The terminal can send a larger set of data via mobile data connection (e.g. GPRS) to a service centre
TYPES OF SENDING MDS:
1. DTMF –messaging:
DTMF is already implemented and available in all GSM networks
2. UUS-messaging:
Implementation requires telecom operators investing in telecommunications network infrastructure.
3. USSD-messaging
Steps involved in detection of accident
1. Pre-certification
2. Application tests
i. Manual initialization
ii. Automatic initialization
3. Environmental tests
ADVANTAGES:
The primary task of this system will be to save the lives of people from accidental deaths.
It is estimated that the e-Call system could save up to 2 500 lives a year in the EU
The reduction of response time has pattern of
40%-in urban areas
50%- in rural areas
CONCLUSION:
This e-call technology is highly efficient and is going to play a predominant role in future emergency service system.
The day is not far when each and every car or vehicle is equipped with the e-call devices
