Design and Development of Smart Fleet System using Global Positioning System

Now a days, Vehicle tracking system plays a major role in our daily life. As the technology grows, vehicle thefts are increasing enormously. This paper proposes to design an embedded system which is used to track and position any vehicle by using Global Positioning System (GPS) and Global system for mobile communication (GSM). This helps in monitoring and reporting the status of the moving Vehicle on demand continuously. So, ATMEGA328 microcontroller is serially interfaced to a GSM Modem and GPS Receiver through serial communication protocol RS 232. In this, driver circuit is used to covert TTL voltages into RS 232 voltage levels. Identifying the position of the remote vehicle is done by GPS modem continuously. The current location details like vehicle longitudes and latitudes of the remote vehicle is sent through GSM modem. The output is acquired from GPS modem and displayed on the LCD display. The same data is transmitted to the mobile at the other end from where the position of the vehicle is demanded. Based on the request placed by the user, the position of the vehicle is automatically sent to the corresponding mobile number. So, this project has been implemented to identify lost vehicle, know the status of moving vehicle from remote location and send the information to the user's mobile number.
