Automatic Escalator System”

INTRODUCTION 

1.1 Introduction 


            I this chapter, I will introduce and explained briefly of my project that titled “Automatic Escalator System”. The objectives and scopes are very important because it will guide the whole process and also gives the right way to discover of completing this project.

1.2 Project Objective            This   project is developed to control an escalator automatically. The main modules in this project are Human sensor, Microcontroller unit, Driver unit and Escalator motor. When any one steps on the escalator, it senses that someone wants to go up or down.  It automatically sends signal to the microcontroller.  It automatically on the motor of the escalator.When the escalator starts, if another steps on the escalator, the microcontroller calculates the time the previous one come in and accordingly it stops the escalator when the first one reaches the particular place. The Microcontroller programs are written in assembly language. This will be very useful in industries, institutions etc.  In future this can be implemented with artificial intelligence.


1.3 Scope of Project
                  This automatic escalator system is using AT89S52 micro controller unit and          LM7805voltage regulator IC . The program is designed as per the requirements to fulfill the aim of project.
