ABSTRACT:
Security in travel is primary concern for every one. This Project describes a
design of effective alarm system that can monitor an automotive / vehicle / car condition
vehicle to the family members of the traveling persons. This project uses a piezo-electric
sensor which can detect the abrupt vibration when an accident is occurred. This sends a
signal to microcontroller.
This Project presents an automatic vehicle accident detection system using GPS
and GSM modems. The system can be interconnected with the car alarm system and alert
the owner on his mobile phone. 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 Microcontroller processes this information and this processed information is
sent to the user/owner using GSM modem A GSM modem is interfaced to the MCU. The
GSM modem sends an SMS to the predefined mobile number and informs about this
accident. This enable it to monitor the accident situations and it can immediately alerts
the police/ambulance service with the location of accident.
The project is built around the AT89S52 micro controller from Atmel. This micro
controller 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 four mobile numbers. This numbers can be changed at any
time by the user using a 3X4 key pad. These numbers are stored in EEPROM.
