Accident detection for release airbag using GSM, GPS&MEMS using ARM7.

Abstract :

Speed is one of the basic reasons for vehicle accident. Many lives could have been saved if emergency service could get accident information and reach in time. Nowadays, GPS has become an integral part of a vehicle system. This paper proposes to utilize the capability of a GPS receiver to monitor speed of a vehicle and detect accident basing on monitored speed and send accident location to an Alert Service Center. The GPS will monitor speed of a vehicle and compare with the previous speed in every second through a Microcontroller Unit. Whenever the speed will be below the specified speed, it will assume that an accident has occurred. The system will then send the accident location acquired from the GPS along with the time and the speed by utilizing the GSM network. This will help to reach the rescue service in time and save the valuable human life.

AIM :

              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

Description :

              Vehicle tracking system is one of the hot topics in embedded systems industry. By using this project a vehicle can be tracked any where on the globe.

             In this project AT89S52 communicates with LCD, GPS module and GSM modem. This system will be placed in a moving vehicle. The AT89S52 will poll GPS module in prefixed intervals and sends the vehicle location information (Latitude  & Longitude) to central station over GSM network. \

            When ever any accident occurs mems sensor detects the vibration of the vehicle and sends mechanical force, to AT89S52, by using GPS, we will get particular location where accident occurs, then GSM sends message to authorized members & 108.

            One more best feature is when ever any authorized people gives message to GSM at accident location then it sends back the message of the accident location long and lat values.
