Real-Time Vehicle Data Logging System Using GPS And GSM

摘要

Abstract: This paper proposes and implements a low cost Vehicle Data Logging System using GPS and GSM. This system allows a user to trace the present and past positions recorded in SD card. This system also reads the current position of the vehicle using GPS, the data is sent via GSM service from the GSM network. The vehicle's position including the driving speed, the UTC time and data are stored in the SD card for live and past tracking. All of that GPS data is sent to PIC 18F4520 by the Universal Asynchronous Receiver/Transmitter (UART) and also store in SD card. GSM also uses UART to transmit. To know the position of the vehicle, the owner sends a request through a SMS. The SMS sends to the authorized person through the GSM network. The travel history of the vehicle are stored in a file on an SD card in FAT format.This system is very useful for car tracking, for adolescent driver being checked by parent (speed limit exceeding, leaving a specific area). V The developed system is easy to use, requires no additional hardware, and permits the selection of the amount of data and the time intervals between the data recordings. In addition, the collected data can easily be transferred to a computer via a connected serial port.
