INTRODUCTIONINTRODUCTION

The main intention of this project is to

find the accident spot at any placefind the accident spot at any place

This project contains MEMS , GSM

module and a GPS modem interfaced

to the PIC microcontroller

contd…

Global system for mobiles(GSM)

technology is used to establish

cellular connection

GSMGSM

cellular connection

GSM is a digital cellular

communication system

It is used for transmitting mobile

voice and data services

GPSGPS

GPS(Global Positioning System)

GPS is used to trace the positionGPS is used to trace the position

GPS Receiver gets the location

information from satellites

MEMSMEMS

MEMS(microelectromechanical system) is a technique of combining

electrical and mechanical componentelectrical and mechanical component

together on a chip

The device typically converts measured

mechanical signals into electrical signals

ABSTRACTABSTRACT

MEMS Sensor used to detect abrupt vibration when an accident occurs

Detection and messaging system Detection and messaging system composed of a GPS receiver, microcontroller and GSM modem

GSM modem sends message to the predefined mobile number

FEATURESFEATURES

PIC 16F73 is a 28 pin IC

4 K bytes flash program memory

192 bytes RAM192 bytes RAM

8 bit , 5 channel ADC

22 input / output pins

3 timers/counters

GSM MODEMGSM MODEM

GSM modem is used to send information

collected from GPS module along with other

details to a specific mobile number

GPS MODULEGPS MODULE

GPS module always receives the information

from satellites regarding the position of the

place where the accident occurs.

MEMS CHIPMEMS CHIP

Whenever any accident occurs MEMS chip

detects and sends electrical signal to the

ADC channel of the PIC microcontrollerADC channel of the PIC microcontroller

POWER SUPPLYPOWER SUPPLY

Power supply unit provides regulated

5v power

The power supply circuit consists of a bridge rectifier which is then passed on to the regulator through a

filter circuit

MAX 232MAX 232

MAX 232 is an dual driver / receiver

It is used to convert the TTL logic level to

RS232 logic levels during serial RS232 logic levels during serial

communication if microcontrollers with PC

WORKINGWORKING

Whenever accident occurs MEMS sensor detect and sends electrical signal to the ADC channel of the PIC signal to the ADC channel of the PIC microcontroller

By using GPS , we get particular location where accident occurs,then GSM modem sends message to authorized mobile number

CONTD..CONTD..

The GPS positioning is done in the form of latitude and longitude along with the exact location of the place with the exact location of the place by making Google maps

ADVANTAGESADVANTAGES

The immediate medication will be provided to the accident victims in the remote areasthe remote areas

Mobile number can be changed at any time

DISADVANTAGESDISADVANTAGES

In some places where there is no provision of GSM networks it is difficult for communicationdifficult for communication

APPLICATIONS &APPLICATIONS &

FUTURE SCOPE FUTURE SCOPE

Automotive Security System

This system can be interfaced with Vehicle

Airbag System

This can also be developed by

interconnecting a camera to the controller

module that takes the photograph of the

accident spot that makes tracking easier

CONCLUSIONCONCLUSION

To take immediate action when an accident occurs by alerting the respective people by sending respective people by sending message
