M.Kamaraju / International Journal of Engineering Science and Technology Vol. 2(8), 2010, 3707-3711 A NOVEL DESIGN OF LOW COST REAL TIME VEHICLE NAVIGATION SYSTEM Prof.M.Kamaraju Professor & Head, Department of ECE Gudlavalleru Engineering College, Pin Code: 521356 Gudlavalleru,A.P, INDIA Abstract: A low cost GPRS based vehicle navigation system is developed using ARM processor for real time application. The main core of the system is an embedded hardware along with Java/J2EE. The embedded device communicates with GSM network which is accessible from anywhere .This system eliminates large maintenance. In PC, Java programming is used for getting the data from serial port and given to the database (SQL SERVER).In the front end, programming code is written in J2EE.The latitudes and longitudes are received through GSM network and stored in the data base .With the help of these values the vehicle navigation can be seen on google map. Keywords: GPRS,ARM, GS, J2E, Internet. 1. Introduction An automotive navigation system [R Prasad (2005)] is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. The GPS / GSM vehicle tracking system[E Bekiroglu (2005)],[Bj E Marca (2000)], it is an idea design not only for GPS real time tracking, but also a complete GSM alarm controllable by user's mobile phone message. GSM and GPRS are developed for cellular mobile communication The GPS tracking solution, with the tracking software and maps. Users can set up a complete tracking station in a PC.There is no need for the costly web server and software. The all-in-one system includes the GPS / GSM tracking main unit in google earth map. Track and control the vehicles using just a PC or Laptop. A GPRS connection with unlimited duration of connectivity is charged only for the data package transfers.This is adopted in several mobile remote control/access systems. GPRS becomes a cost- effective solution only if the data transfers can be optimized. Once a GPRS connection has been established, queried data can be relayed to the client via a central server commands sent, using TCP/IP protocol and User Datagram protocol. It requires large maintenance. In this work embedded hardware developed using the GPS, GSM, ARM processor and writing the code in J2EE to track the vehicle position. It eliminates the large maintenance. 2. System Overview The block diagram of the system is shown in Fig.1.The transmitter section consists of a ARMLPC2148, GPS module, GSM transmitter, temperature sensor, relay, keypad, LCD.The microcontroller extracts the latitude and longitude values according to the code. By using the keypad entering the mobile number of the receiving part of the GSM mobile 2 in the LCD buffer.For displaying relay sends the message for every 20 seconds to the GSM mobile 1 passes to the GSM mobile 2 .This interface with the RS232 cable of the computer system respectively. The GPS module receives the tracking information of the satellites and codes it according to the NMEA protocol. This protocol sentence includes several commands. The receiver section consists of a GSM receiver and a PC. The information sent from the transmitter section is received by the GSM receiver and then traced by using PC at the control station. This vehicle tracking system employs a GSM/GPS Module for continuously updating the geographical location of the vehicle to the base station.The latitudes and longitudes will be plotted on the maps and stored in PC.
