RFID based vehicle accident detection and messaging system using GSM and GPS mode

Security in travel is primary concern for everyone. This project presents an automotive localization system using GPS and GSM-SMS services. When the vehicle is involved in an accident immediately an SMS will send to predefined numbers with GPS location by using vibration sensor. A switch is provided because if the person presses the switch it indicates the person is in a safe condition. RFID is used to know the information about the vehicle; information is nothing but the vehicle number and location by using GPS. This system also can be interfaced with vehicle airbag system. This detection and messaging system is composed of a GPS receiver, microcontroller and a GSM modem. GPS receiver gets the location information from satellites in the form of latitude and longitude. The project is built around the LPC2148 microcontroller from Atmel. This microcontroller provides all the functionality of the SMS alert system. It also takes care of filtering of the signals at the inputs. The uniqueness of this project is, not only alerting the neighbors by its siren, but also it sends a caution SMS to two mobile numbers.
