ACCIDENT MESSENGING SYSTEM
(Thiran 2014)
INTRODUCTION:
It would be amazing if an accident can locate itself and sends a message of its location for help, it would save numerous lives. This project presents an accident alert system which instantly sends text messages to the predefined mobile numbers about the accident.
CIRCUIT COMPONENTS:
1.PIC Microcontroller 16F73
2.MEMS Chip ADXL202E
3.GSM Modem
4.GPS Module
5.Power Supply
6.Voltage Level Convertor
/*these components can be bought from electronics shop (near Fivelamps) in the name of order */
ABOUT THE COMPONENTS:
MEMS:
The MEMS (Micro Electro Mechanical System) is a kind of sensor that can detect acceleration, tilt, shock and vibration. The basic principle of operation behind the MEMS accelerometer is the displacement of a small proof mass etched into the silicon surface of the integrated circuit and suspended by small beams.
PIC MICROCONTROLLER:
The main advantage of PIC (Programmable Interface Controller) is that it can be operated at variable frequency level. In this project PIC16F73 is used because of its low cost, wide availability, re-programming with flash memory capability.
WORKING:
Whenever the accident occurs, mechanical vibrations are produced and these vibrations are detected by the MEMS sensor. MEMS sensor converts the mechanical vibrations into electrical signals and the signals are sent to the ADC channel of the PIC microcontroller.
By using GPS we get the information about the particular location where the accident occurs. Then the GSM modem sends messages to the authorized mobile numbers.

By using GPS we get the information about the particular location where the accident occurs. Then the GSM modem sends messages to the authorized mobile numbers.
/*But here in demonstration due to unavailability of GPS& GSM receivers we have used a seven segment display interfaced at the output pin of MICRO-CONTROLLER.*/
ADVANTAGES:
Immediate medication can be provided to the accident victims in the remote areas.The mobile number can be changed at any time.Immediate action can be taken when an accident occurs by alerting the respective people by sending messages. It is used in vehicle security system.This system can be interfaced with vehicle airbag system.This can also be developed by interconnecting a camera to the controller that takes the photograph of the accident spot that makes the tracking easier.
