2. INTRODUCTION The main intention of this project is to find the
accidentspot at any place and intimating it to ambulance through theGPS
and GSM networks The GPS based vehicle accident identification
modulecontains MEMS,GSM module and a GPS modem connectedto the
microcontroller Global System for Mobiles (GSM) technology is used
toestablish cellular connection GPS is used to trace the position of the
vehicle
3. INTRODUCTION…. Now-a-days, it became very difficult to know that
anaccident has occurred and to locate the position where it
hashappened There is no system of identification and intimationregarding
an accident in previous Later on the SMS Service begins for intimation
purpose GPS and GSM makes the usage for intimation andidentification of
place
4. PREVIOUS SYSTEMWhen an accident occurs the information only is
sent throughGSM but there is no possibility to locate the spot
5. PROPOSED SYSTEMThis Project presents an automotive localization
systemusing GPS and GSM-SMS services

2. 9. POWER SUPPLYThe power supply circuit consists of a transformer
connected toa bridge rectifier which is then passed on to the LM
7805regulator through a filter and then sent to the LM 317 regulator
10. Global Positioning System27 SatellitesOrbit the Earth twice a
dayEquipped with an Atomic clockGPS Receiver3-D TrilaterationGPS
Receiver locates 4 satellites above itThen it calculates the distance to GPS
satellites bytiming a signals journey from satellite to receiver
11. Global Positioning System….
12. GPS MODULEThe GPS module ProGin SR-87 series is usedHigh
performance receiver tracks up to 20 satellitesThe module communicates
with application system viaRS232 with NMEA-0183 protocolAverage Cold
Start time under 42 secondsNMEA 0183 a combined electrical and data
specification forcommunication between marine electronic devices such
asGPS receivers, anemometer ,etc
13. GSM Modem A GSM modem is a wireless modem thatworks with a
GSM wireless network A wireless modem behaves like a dial-
upmodem The main difference between them is that adial-up modem
sends and receives data througha fixed telephone line while a wireless
modemsends and receives data through radio waves
14. GSM MODEM….The GSM network is used to provide
communicationfrom one place to otherThe GSM module using consists of
a Mobile Station andSIMThe commands that are using to provide
communicationare AT CommandsThe AT commands specifies the GSM
technology and arerelated to SMS service
15. General Characteristics of aGSM ModemReading, writing and deleting
SMS messages Sending SMS messages Monitoring the signal strength
Monitoring the charging status and charge level of the batterReading,
writing and searching phone book entries.Thenumber of SMS messages

3. that can processed by a GSMmodem per minute is very low -- only about
six to ten SMSmessages per minute
16. MEMS MEMS or Micro Electro Mechanical Systems is atechnique of
combining Electrical and Mechanicalcomponents together on a chip, to
produce a system ofminiature dimensions
17. LCD A liquid crystal display (commonly abbreviated LCD) is athin, flat
display device made up of any number of color ormonochrome pixels
arrayed in front of a light source orreflector It is prized by engineers
because it uses very small amountsof electric power, and is therefore
suitable for use in battery-powered electronic devices
18. LCD….In our project, the LCD used to display the status and position
of thevehicleThe number to which the position of the vehicle is to be
delivered , alsodisplays on the LCD such that changes can be made if
necessary
19. FEATURES OF LCD Ability to display numbers, characters and
graphics Read and Write the DATA Adjust the Contrast Low power
consumption

22. WORKING When ever any accident occurs mems sensor detects
andsends mechanical force to ARM, by using GPS, we will getparticular
location where accident occurs, then GSM sendsmessage to authorized
members & 108 One more best feature is when ever any authorized
peoplegives missed call to GSM at accident location then it
sendsmessages of the accident location
23. WORKING….
24. ADVANTAGES DISADVANTAGES The vehicle which has In some
places where there undergone to an accident is no provision of GSM can

4. be identified by using networks it is difficult for tracking technology without
communication any delay The immediate medication will be provided to
the accident victims in the remote areas
25. FUTURE SCOPE This system can be interfaced with Vehicle airbag
system thatprevents vehicle occupants from striking interior objects such
asthe steering wheel or window This can also be developed by
interconnecting a camera to theController Module that takes the
photograph of the accident spotthat makes the tracking easier
26. CONCLUSIONTo minimize the deaths and the severe conditions due
to accidentsthe GPS and GSM technologies are used where immediate
actionwould be take place by the ambulance/police service which
mightreduces the severity Pie Diagram representing the cause of deaths
