This document presents an accident reporting system using a MEM sensor that can detect vehicle accidents and send alerts. The system includes a MEM sensor to detect vibrations during accidents, an LPC2148 microcontroller, a GSM module to send SMS alerts, a GPS module to locate the accident site, and an LCD display. When an accident occurs, the MEM sensor detects it and the microcontroller activates the GSM module to send an SMS with the accident location from the GPS module to emergency services. This allows for faster emergency response times and treatment for victims. The system aims to reduce accident response times and property and life losses.

3. INTRODUCTION
• Advent of technology leads to increased traffic hazards and road
accidents.
• Huge loss of life and property due to poor emergency facilities.
• The system detects the vehicle accident using vibration sensor or
MEMS sensor.
• It sends a message to police control room with the location of
accident to minimise the time required for legal police process, and
a victim can get fast treatment.

6. GSM(Global System for Mobile
communication)
• Now a days, GSM service is easily available to everyone.
• You need not to carry a different remote.
• It is used to send SMS.
• It provides serial interface.
• Can be controlled through serial AT commands.

7. MEM SENSOR
• It is the most applicable Micro-electromechanical system.
• It is a small, thin, low power complete 3 axis accelerometer.
• It can measure the static acceleration of gravity in tilt sensing as well
as dynamic acceleration resulting from motion, shock or vibrations.
• The output signals are analog voltages that are proportional to
acceleration.

8. LPC 2148
• 16/32 bit ARM -7TDMI-S microcontroller.
• One or two 10 bit A/D converter.
• 8 to 40 kB of on-chip static RAM and 32 to 512 kB of on-chip flash
program memory.
• Single 10-bit D/A converter provides variable analog output.
• Single power supply CPU operating voltage range of 3.0V to3.6V with
5 V tolerant I/O pads.
• On-chip integrated oscillator operates with an external crystal in range
from 1 MHz to 30 MHz and with an external oscillator up to 50 MHz.

9. GPS(Global positioning system)
• It is a system which determine location accurately anywhere in the
world.
• It has 3 segments:
o Space Segment – 24 satellites.
o User Segment – all of us with receivers, phones, etc.
o Control Segment – 6 ground stations located around the world.

11. LIQUID CRYSTAL DISPLAY
• An LCD is a displaying device used to display the character.
• 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 displayed on the LCD such that changes can be made if
necessary.
• The standard dimension of a 4x20 display unit is 68x27 mm for a
single square unit on the display board.

12. ADVANTAGES &
DISADVANTAGES
Advantages:
• Vehicle which has undergone accident can be identified using
tracking technology.
• Few sensors are able to capture a wide variety of movements.
• User convenience and effective power saving.
• Immediate medication will be provided to the victims in remote
areas.

13. Disadvantages:
• Existing system do not work if the system itself damaged in the
vehicle accident.
• System will not work in case it is not in the GSM network coverage
area.

14. APPLICATIONS
• Cost effective solution for control of accidents.
• It can be used in anti-lock breaking system.
• This system can be interfaced with vehicle airbag system.

15. FUTURE WORK
• There is a scope for improvement and as a future implementation,
we can add a alcohol sensor to prevent accident and a digital camera
to know the more detail about the accident.
• This system can be interfaced with vehicle airbag system that
prevents vehicle occupants from striking interior objects such as the
steering wheel or window.

16. CONCLUSION
• This system can shorten the alarm time greatly and locate the
accident spot accurately.
• It will save the rescuers from wasting their time in search.
