Energy Saving Systems for Railway Platforms

INTRODUCTION

In todays world. Microcontroller based control systems are gaining more importance, because

of their number of advantages over the manual control system. The microcontroller based

control systems are more reliable, accurate and easily programmable. Hence they allowed

user to perform data transfer, data security, design the control system and tracking the

changes in the system.

In this project we have tried to make such a control system for energy saving on platform

lights. e have placed I! sensors on both the sides of station in order to sense the presence

of train. hen any train crosses the I! sensor It cuts the I! beam. This event will be tracked

by Microcontroller. hich will turn "# the lights for limited pervade of time hence saving the

energy wastages and over consumptions

Description:

Microcontroller

This is the most important segment of the project, i.e. the microcontroller 8051 The controller is

responsible for detection and polling of the peripherals status. It is responsible for making. It is

responsible for prioritizing all the devices attached to it. e have used the !T"#$ 8%s51

microcontroller. The !T8%&51 is a lo'(po'er, high(performance )"*& +(bit microcontroller

'ith 8 b-tes of in(s-stem programmable lash memor-. It has got / I* lines, atchdog

timer, t'o data pointers, t'o 12(bit timercounters, si3(vector t'o(level interrupt architecture, a

full duple3 serial port, on(chip oscillator, and a clock circuitr-.

Infra Red (IR) Sensors:

Infra red sensors are a t-pe of light sensors the- function in the infra red part of the fre4uenc-

e will need to drive a lamp with respect to sensors output. e are going to use !elay for this

purpose
