This document describes a wireless accident identification system that uses GPS and GSM networks. The system includes a vibration sensor, microcontroller, LCD display, keypad, relay, GPS and GSM modules. When an accident occurs, the vibration sensor detects it and sends a signal to the microcontroller. The microcontroller then switches on the GPS and GSM modules using a relay. The GPS module obtains the location coordinates which are sent via GSM to an emergency contact. The system aims to quickly identify accident locations to dispatch ambulances.

3. PREVIOUS AND
PROPOSED SYSTEM

4.  The main intention of this project is to find the
accident spot at any place and intimating it to
ambulance through the GPS and GSM networks
 Global system for mobiles (GSM) technology is
used to establish cellular connection.
 GPS is used to trace the position of the vehicle.
INTRODUCTION

5. CIRCUIT COMPONENTS
 Power supply and vibration sensor.
 Microcontroller.
 Liquid crystal display.
 Keyped and DB9 connector.
 DPDT relay.
 GPS module.
 GSM module.

6. POWER SUPPLY AND
VIBRATION SENSOR
 Power supply is a referance to a source of
electrical power.
 Linear Mode Power Supplying is used in
this system.
VIBRATION SENSOR
 The circuit is constructed with
 Pizoelectric plate.
 Operational amplifier
 555 IC Timer.

7. LCD
 Here the LCD is used
to display the status
and position of the
vehicle.
 The number to which
the position of the
vehicle is to be
delivered, also display
on the LCD such that changes can be
made if necessary.

8. DPDT RELAY
 The ‘DP’ means that
it is double pole, so
it switches both
side of the circuit.
 The ‘DT’ means that
rather than just
turning on and off, it switches from
one set of wires to another.

9. GPS MODULE
 GPS SYSTEM
27 Satellites
Orbit the Earth
twice a day
Equipped with an
atomic clock.
 The GPS module
ProGin SR-87 is
used.

10. GSM MODULE
 The GSM network is used to provide
communication from one place to another.
 The commands that are using to provide
communication are AT commands.
 The AT command specifies the GSM
technology that are related to SMS service.

11. TRACKING

12. TRACKING
OPERATION
 When an accident occurs, the piezoelectric
plate gives electrical signal to MC.
 MC switches GSM and GPS network by using
DPDT switch.
 GPS receiver takes latitude and longitude
through antenna.
 GSM transmitter sends this information to
control system.

13. IMPLEMENTATION
 The proposed system
can be implemented by
interconnecting the
system to the
automobile.

14. ADVANTAGES AND
DISADVANTAGES
Advantage Disadvantage
 Low cost solution for
automobile position and
status.
 Very useful in case of car
theft situation.
 The immediate
medication will be
provided to the accident
victims in remote areas.
 The biggest problem
blockage of signal
transmission by
mountains, high
building tunnels.

15. FUTURE ENHANCEMENT
 This can be developed
by interconnecting a
camera to the
controller module that
takes the photograph
of the accident spot
that makes the
tracking easier.

16. CONCLUSION
 To minimize the death and the severe
conditions due to accidents the GPS and
GSM technologies are used where the
immediate action would be take place by
the ambulance/police which might
reduces the severity.
