voice based elevator movement and display control technique

Abstract

Elevator is the main part in day to day life .it become transport devices that we are using every day
.elevator is useful to move goods and persons. In this project,we are using the microcontroller AT89S52 .on this microcontroller the elevator controller is constructed to simulate as elevator in the real elevator. This project dissertation documents the results of a research on a microcontroller based elevator control system. It provides useful data to those who want to carry out a elevator Control system research . This System is operated on the Voice of any person which will help the handicap person to Travel form one place to another without any help of other. Microcontroller is become main part of each application now a days. application in each and every automation control like Hand-held communication devices Remote controllers,, automatic and automobiles, security system, telephone printing machines, indicating ,measuring instruments and products of day to day life. The project described here being also a microcontroller based, used for security purpose and in emergency condition. The use of microcontroller in this project is to store the data which is using in the programming for purpose of moving the elevator, process data that will be according to the user wishes.

INTRODUCTION

Elevator is become the main part of our day to day life.elevator is become a transport device that is very common to us
now a days. We use it every day to move goods or peoples vertically in a high building such as shopping center, working
office, hotel and many more things. Elevator is a very useful device that moves people in the shortest time to desired
floor .Lift is the vital part of everyone’s life living in large buildings, and moreover it is the necessary thing in large
buildings or any big construction having number of floors to move from one floor to another. Now a day it is becoming
prestigious thing for the malls, shopping markets ,colleges ,hospitals ,hotels. which are having two or three floors or
more than that. So we are trying to make it more automatic through our project.Speech recognition model is the method by which the elevator can be controlled .and by Speech recognition model we will get input to controlling the elevator. Whenever we are dealing with voice control, the first term come in our mind is Speech Recognition i.e. system should know or understand human voice as input to the speech recognition model. Speech recognition is a technology in which the system will understand the words but not its meaning of the words given by the speech of any person to speech recognition module. Speech is an best and ideal method to controlling the elevaor.In this project we are also going to give indication to the security in emergency situation. In emergency situation means in case of lift failure .it may be the fault because of power failure or may more reasons of power failure .in emergency condition it will indicate to the security person and that time buzzer will ringing on.
