ACCIDENT DETECTION FOR RELEASE AIRBAG USING GSM, GPS&MEMS
Main concentration of this project is to find out the vehicle which is met with an accident by using MEMS sensor and GPS, GSM to release Air bag. This system will be placed in a moving vehicle. The Atmel controller will poll GPS module in prefixed intervals and sends the vehicle location information (Latitude & Longitude) to central station over GSM network. Whenever any accident occurs MEMS sensor detects the vibration of the vehicle and sends mechanical force, to ARM, by using GPS. We will get particular location where accident occurs, and then GSM sends message to authorized members & 108. One best feature is whenever any authorized people gives message to GSM at accident location then it sends back the message of the accident location Long and Lat values. This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulators are used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18V step down transformer. This system can be interfaced with vehicle airbag system that prevents vehicles occupant from striking interior object such as the steering wheel or windows. This can also develop by interconnecting a camera to the controller module that takes the photography of the accident spot that makes the tracking easier.
