Introduction:

GPS and GPRS based real time vehicle

tracking on Google Earth

Abstract:

The project aims in designing a system which is

capable of continous monitoring of path of the vehicle on

PC with Google Earth Application.

This project consists of GPS receiver present in the

vehicle system which continuously gets location

information from the satellites and GPRS modem; placed in

vehicle system,. The GPRS modem, which is present in the

vehicle, will continuously send location information into a

web-link.

GPS is the acronym for Global Positioning System.

It is employed to find the position, velocity, time of

anything located on the earth. This information is provided

by the GPS receiver with the help of the data it receives

from the satellites.

Micro controller forms the controlling module and

it is the heart of the device. The controller performs the

functionality of receiving data from the GPS. The

microcontroller is programmed in such a way that the data

from GPS receiver is processed and continuously sent

through GPRS modem. The data is uploaded to a pre-

defined web-link through a GPRS modem interfaced to the

Microcontroller. The received data is tracked on the Google

Earth application in the PC. A line driver MAX232 is used

to convert CMOS levels to RS232 levels. The

Microcontroller is programmed using Embedded C

language which provides effective environment in

performing the task.

Vehicle tracking Reduce the cost by knowing in real-timethe current location of a vehicle such as atruck or a bus The location of a vehicle is used by a fleetOperator to efficiently plan a schedule inOrder to reduce the transportation time anddistance

The system architecture: GPS tracking and GSM modules

The system has two main modules, as shown in figure (2). The first module is the tracking device which is attached to the moving automobile. This module composes of: a GPS receiver,Microcontroller and a GSM Modem. The GPS Receiver retrieves the location information from satellites in the form of latitude and longitude real-time readings. The Microcontroller has threemain tasks: to read certain engine parameters from automobile data port (OBD-II), to processes the GPS information to extract desired values and to transmit this data to the server using GSM modem by SMS. The

chosen engine parameters are: RPM, engine coolant temperature, vehicle speed, percent throttle.The second module consists of a recipient GSM modem and workstation PC. The modemreceives the SMS that includes GPS coordinates and engine parameters. This text is processedusing a Visual Basic program to obtain the numeric parameters, which are saved as a MicrosoftOffice Excel file. The received reading of the GPS is further corrected by Kalman filter. Totransfer this information to Google Earth, the Excel file is converted to KML (Keyhole MarkupLanguage) format. Google Earth interprets KML fileandshows automobile’s location andInternational Journal of Computer Science & Information Technology (IJCSIT) Vol 3, No 6, Dec 201177engine parameters on the map. The system’s efficiency is dependable on the sufficiency of theused communication network.An additional setting could be implemented to interface the system to the car’s alarm to alertthe owner on his cell phone if the alarm is set off. The automobile’s airbag system can also bewired to this system to report severe accidents to immediately alert the police and ambulanceservice with the location of the accident.Figure 2. The system architecture: GPS tracking and GSM modules. 4. Hardware specification

The tracking unit, as shown in figure (3), consists of two main inputs: The first receivedinput is the GPS output, which has a sentence based on NMEA 0183 standard. The other inputis obtained by the automobile data port, typically called ON Board Diagnostics port, version II(OBD-II). The unit sends an SMS using Hayes command (AT Command).

Schematic diagram of in-vehicle tracking unit.

On-Board Diagnostics port (OBD-II) is a universal automotive protocol supported by modern automobilesTo retrieve diagnostic errors over a Controller Area Network (CAN) bus of the microcontroller (MCU)[11].The used GSM module is of type SIM900D, this modulesupports standard AT command and compatible with several GSM networks. Transmissionparameters are set to: Baud rate is set at 19200 bps, the data is 8N1 format, and flow control is set to none. For this study, we chose certain parameters to show the status of the engine: RPM, engine coolant temperature, vehicle speed and percent throttle
