摘要:This paper is for transportation security and fleet management. An embedded device is designed and fabricated into PCB. The embedded device having SIM908, integrated GSM/GPS module, is kept inside vehicle which acquires the speed and location of the vehicle and send data to the server. The fuel level detection circuit calculates the fuel level from the fuel gauge which is present in all the vehicles. Connecting to internet requires additional money deducted by internet provider and the more use of battery. In order to be efficient, SMS function is included to start/stop internet connection. When the owner needs to track the vehicle, a SMS is sent to the device which then establishes the connection to the TCP server through GPRS. Data such as location speed and fuel level is sent to the server and stored in a database. The web page and android application designed for this purpose tracks the vehicle three dimensionally and show them in integrated map. Emergency call function is designed. The driver can call to the police, ambulance and the owner of the vehicle in emergency situations. The owner can dial a call to the vehicle at situations when the driver goes beyond the limits like high speed driving and wrong direction.
