Department of Electricals and Electronics Engineering,Sri Manakula Vinayagar Engineering CollegeOBJECTIVEThe aim of our work 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)

Sensors- Vibration Sensors- MEMS (Micro-Electro-Mechanical Systems) SensorsRS 232 (Data terminal equipment)EEPROMBuzzers16x2 LCDRegulated 5V, 500mA power supplyVoltage RegulatorBridge type Full wave rectifierPIN DIAGRAM OF AT89S52

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.
