Bus Security and Tracking System Using GSM

Abstract

This paper summarizes our work on the design and implementation of GSM-based system for tracking the location of buses provided for public transportation. The system consists of three main modules: In-Bus Module, Bus-Stop Module and Base-Station Module. When bus leaves from BASE Station, the GSM tag at BASE-Station is read by the GSM reader in the In-Bus Module and the tag data is then sent to BASE-Station via GSM. By using the signals from AT89S52 microcontroller, GSM modem is used to send appropriate GSM tag data to the BASE-Station. An entry corresponding to the bus is created and entered into the database at BASE-Station. BASE-Station Module sends the data about bus, its current location and remaining time for arriving particular bus stop to the Bus-Stop modules via GSM. Bus-Stop Module is installed at every bus stop and consists of GSM, GSM tag and LCD display all interfaced to a microcontroller. This module then display the data received form BASE-Station on LCD displays. AT89S52 microcontroller is the main controlling device which controls and synchronizes all the operations by receiving the data from GSM tag. This paper is embedded based, embedded means dumping of software in to the hardware. Here software code is written and debugged with the help of micro version Keil. Keil converts the asm file into hex file and this software code is dumped into the microcontroller AT89S52 using dumping kit.
