is to find the vehicle accident location by means of sending a
message using a system which is placed inside the vehicle.
The message can be sent to the any subscriber or to the
ambulance service.MATERIALS REQUIREDMicrocontrollers 89C52
Derivative of 8052 microcontroller LPC 2148 arm processor based
chipsAT89S52 - made for the accident alert systemMAX 232 - dual
driver/receiver GPS ModemGSM Modem (SIM300 System)

WORKING PRINCIPLEWhenever accident occurs MEMS sensor detects
and sends mechanical force to ARM by using GPS, we will get
particular location where accident occurs, then GSM sends message
to the subscribers and also to the 108 AMBULANCE SERVICE.One more
best feature is when every subscriber gives a missed call to GSM at
accident location, then it sends the messages of the accident
location.FLOW CHART
OPERATIONAL CIRCUIT
PROCESS AT TRANSMITTER SECTIONHere, MEMS senses the vibration
during accident and sends the electrical signal to LPC 2148. Then
MAX 232 converts TTL/CMOS levels to RS232 logic levels during
serial communication of microcontrollers with PC/Mobile.
PROCESS AT RECIEVER SECTIONHere the message is received using
GPS receiver and displayed in LCD.

APPLICATIONSUsed in auto motives and transport vehicles- from
lighter vehicles like cars, to heavier auto motives like ships and
aero planes.Security and remote monitoring of vehicles especially
during military operations.This system is also can be interfaced
with Vehicle airbag system such that when the sensors detect the
accident, the air bags get opened. THANK YOU ..!!
