GPS BASED VEHICLE TRACKING AND SECURITY SYSTEM.
[attachment=22573]
Abstract:
The Global Positioning System is usually called as GPS. The NAVSTAR GPS (Navigation Signal Timing and Ranging Global Positioning System) is a collection of Satellites, which monitors the Longitude and Longitudes of a particular position. A typical GPS receiver calculates its position using the signals from four or more GPS satellites. Four satellites are needed since the process needs a very accurate local time, more accurate than any normal clock can provide, so the receiver internally solves for time as well as position.
GSM (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voice and data services. Here we are using it only for transmitting and receiving the messages. GSM wireless data module is used for remote wireless applications, machine to machine or user to machine and remote data communications in many applications.
The GSM and GPS modules can be serially interfaced to the microcontroller which has UART. Both the modules are connected to MAX232 through a relay for switching alternatively.
Initially the GPS continuously takes the data from the satellite and stores the latitude and longitudinal positions in microcontroller’s buffer. If we want to know the path of the vehicle we need to send a message to the GSM which gets activated by receiving our message. At the same instant the GPS gets deactivated with the help of relay. As soon as the GSM gets activated it takes the last received latitude and longitude positions from the buffer and sends a message to the particular number which is executed in the program. After the message has been sent to the user the GSM gets deactivated and similarly the GPS gets activated. This is a cyclic process.
The applications for this project are in military, Navigation, Automobiles, Aircrafts fleet management, remote vending, remote monitoring, remote control, security systems, tele-services, etc.
