ACCIDENT IDENTIFICATION USING RF

AIM:

The aim of this project is to implement an accident identification system wirelessly using one of the wireless communications Radio Frequency.

DESCRIPTION:

Generally we don’t have any information while

our closest friends or family members met an accident

at some distance. Due to that we may face severe

situations at sometime. To avoid this problem we are

using accident identification system using RF, by this

we get the intimation very quickly and we save their

lives by taking some correct decision.

In transmitter section we are using H-Bridge, motors, vibration sensor, microcontroller, RF transmitter with RF encoder. In receiver section we are using RF receiver with decoder, microcontroller, LCD. How the identification will done is when the vehicle is moving, whenever the vehicle met an accident the vibration sensor which is attached to the vehicle, senses the vibrations and send this signal to the micro controller. According to the program controller takes appropriate decision that stops the vehicle immediately and at the same time the message i.e., vehicle met an accident will transfer from controller to the RF transmitter via RF encoder. From that it is received by the RF receiver and it is passed to the controller at the receiver section via RF decoder. According to the received information, corresponding message will display on LCD.
