PROJECT DESCRIPTION

The project is designed to detect a crack, if any, on the railway track and alert the respective railway department. This is to avoid rail accidents by using latest communication technologies. In this project GSM communication protocols are used to convey the message of crack detection via SMS.

This project uses a microcontroller from 8051 family. The primary objective of this project is to detect the crack in the railway track and alert the nearby station through effective and highly reliable communication mode.

To demonstrate this project, two rails forming the part of a track are made using a pair of wire which is connected with a detachable jumper in between each wire/track. Removing the detachable jumper creates a fault in the respective track; otherwise it is generally shorted by the jumper wire to simulate healthy track condition.

Removing the jumpers result in driving transistors delivering a different logic to the controller. The program thereafter takes over to send an SMS through GSM modem interfaced through a level shifter IC to the microcontroller. An LCD is also interfaced to the MC to display the status of GSM and track condition.

Thus the proposed model is designed to recognize the cracks in the railway tracks and provides instant information to the concerned railway authorities. The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier.

The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Output video enables even a layman also to decide the kit / kit type are good. I liked the different kit types and all the material needed for project we got in kit itself. Working good / easily able understand. Everything about the kit is good.
