Accident detection for release airbag using gsm, gps&mems using arm7.

  1. 1. Accident detection for release airbag using GSM, GPS&MEMS usingARM7ABSTRACT:Main concentration of this project is to find out the vehicle which is met with anaccident by using MEMS sensor and GPS, GSM to release Air bag.Vehicle tracking system is one of the hot topics in embedded systems industry.By using this project a vehicle can be tracked anywhere on the globe. In this projectARM LPC2148 communicates with LCD, GPS module and GSM modem. This systemwill be placed in a moving vehicle. The ARM LPC2148 will poll GPS module in prefixedintervals and sends the vehicle location information (Latitude & Longitude) to centralstation over GSM network.When ever any accident occurs MEMS sensor detects the vibration of the vehicleand sends mechanical force, to ARM, by using GPS, we will get particular location whereaccident occurs, then GSM sends message to authorized members & 108.One more best feature is when ever any authorized people gives message to GSMat accident location then it sends back the message of the accident location long and latvalues.This project uses regulated 5V, 750mA power supply. 7805 three terminal voltageregulator is used for voltage regulation. Bridge type full wave rectifier is used to rectifythe ac output of secondary of 230/18V step down transformerwww.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur

  4. 4. Applications: It is used for vehicle tracking When ever any authorized people gives message to GSM at accident locationthen it sends back the message of the accident location long and lat values.Advantages: It reduces the death percentages in accidents It gives immediate information to the belonging one Simple and reliable Low cost Easily applicablewww.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
