Design of remote control alert system

CHAPTER ONE

INTRODUCTION

1.1          
                  OBJECTIVE OF PROJECT

The need
for a remote control alert system that can control domestic appliances and
various lighting points and sockets has often been a concern for users. At
times users find it inconvenient and time consuming to go around turning their
appliances on or off each time there is power outage or each time they are
leaving the house for work. It has also often led to damage of appliances due
to the fact that an appliance was not turned off before leaving the house.

          The
Objective of putting up this project, therefore, is to design an equipment that
can facilitate a convenient and easy way of controlling our domestic
appliances, lighting points and sockets especially in powering them, without always
going to appliances physically by ourselves.

          This objective will be accomplished using various
components which include a Microcontroller (AT89C51) which acts as the backbone
of the project together with other components.

1.2           
JUSTIFICATION OF PROJECT

The ease
of putting our appliances, lighting points and sockets on or off has made it
necessary to develop this system in order to control our appliances, lighting
points and sockets from a central point using a remote control. The issues of
always forgetting our appliances ON when leaving the house has often caused
fire outbreak and explosion in homes and this is another reason that led to
designing and construction of this project.

1.3    SCOPE OF DIAGRAMS
IN PROJECT

               In this project report, the
diagrams will range from simple block diagrams to complex circuit diagrams
which will comprise mostly of common electrical and electronics symbols. Some
of the diagrams that will feature in this report will be used as the main block
on which certain parameters will be explained upon. Relevant electronic
components will also be shown and described.

           This project report will also
contain an outline of the circuit diagram as it is seen physically. The package
design diagram will be included showing the width, height in millimeter (mm).

PROJECT  REPORT ORGANIZATION

Chapter
1 serves as the introductory chapter where I try to relay the concept and
acceptable reasons why the project should be implemented for the intending user
of the work. Thus, showing the block diagram of the design and a scope of
diagram for the entire project design.

Chapter
2 deals with the literature review where it will be discussing the origin of
this project design. In the origin of the project, we will be looking at what
brings about the three phase selector in our day to day activity and how the
idea of designing this project comes about.

A
description of the Project is also given where the 2 sections of the project
are discussed and the various components contained in the sections also
mentioned.
