CHAPTER ONE
INTRODUCTION
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.
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.
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. The use and importance of this project
design will also be mentioned here. It will be looking at the best place where
this project design can be use and where it cannot. This chapter will also make room for adding
additional information that will help in the actualization of this project
design.
Chapter 3 treats the methodology of
this project design. It comprises of the information gathering; the source of
the materials used in designing and writing the project report, data analysis;
the components and devices used in the course of designing this project will be
analysis to know their basic means of operation and how they will help in
putting up this design, system design approach; the possible way to tackled the
project design from scratch, bottom-up; it will treat how the practical detail
was gotten before considering about the general principle of the system design,
choice of design system; it focuses on why the project design was done using a
microcontroller rather than using only digital logic, and also the data flow
arrangement and system flow chart.
In chapter 4, the detail design work
will be presented. It will include the schematic of the design of the various
sections of the design and the source code (in C language) used in programming
the microcontroller.
Chapter
5 will be discussing the system testing, Expected results, and Performance
evaluation.
Summary and conclusion of the
design will be presented in Chapter 6. It will be looking at the problems
encountered in designing the project and possible solutions to them. From the
problems and solutions of this work, the suggestion for further improvement
will be stated.
