ABSTRACT
In most organizations, queues
for services have become a generic problem. This thesis presents a prototyped
wireless menu selection system for electronic-queue based service delivery. The
developed system consists of a microprocessor, interface circuit and an
improvised blue tooth wireless system. The model was configured to depict a
financial institution while the blue tooth wireless technology allows customers
to have remote access to the attendants (cashiers) for account balances (x),
crediting (y) and debiting (z) of accounts through the system interface box using
mobile phone keypad. The developed model showed how electronic-queue based
service delivery could be achieved with great deal of cost benefits from
reduced labour force.
CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF STUDY
There has been continuous quest for man to
improve his well being through, reactions to problems and challenges posed by
his environment. Over the years, attendants in the cafeteria/ fast food joints
use to go from table to table in order to know what customers demanded before
they could serve them. This was a very hectic duty and also slow mode of
service. This has led to an overwhelming need for a device that will always
display the customers’ need on each table.
This project design is simply used to
display the items demanded by each customer. Each table has a remote with three
by four set of menu selection. The processor is able to decode whichever button
is pressed. The tables are numbered. Customer on every table orders the item he
or she needed with the remote. Then, a screen in the kitchen is used to display
the table number and the items demanded.
The major components used in this design
are 8951 microprocessor, crystal oscillator, Electronic switches, Display units
(LCD), Buffer (74244), 3-8 lines decoder (74138), and some other common readily available components.
This project is microprocessor based, which is a dedicated or embedded
controller. This microprocessor is used to control and display information in
the device therefore it can be termed a micro controller because of the
controlling function it performs. The type of micro controller used is the 8951
which is an 8051 family chip.
The 8051 micro controller has an external
Read Only Memory (ROM) but the 8951 has an internal Rom. The 8951 Micro
processor accesses external devices using all of its ports 0, 1, 2 and 3.The
Rom inside the 8951 contains the program that the processor executes on boot
up. The program contained in the processor should be debugged and troubleshot
in order to get the device up and running, if not, any mistake in the program
will lead to improper working of the device. The 8051 operates based on an
external crystal oscillator which it uses to synchronize its operation.
A matrix of light emitting diodes is used
in this prototype instead of liquid crystal display (LCD) to display the
information contained in the program on the screen when the device is boot-up.
This information is displayed in a form that can be understood readily by the user
or the operator. As soon as an input is made using the remote control, an alarm
sounds from a loudspeaker to alert the attendants in the kitchen or
receptionists to
enable them check the screen. The design is reliable and has high efficiency
as a result of the micro controller and some other components used.
1.2 MOTIVATION
The
system of going from table to table in organizations and hospitality industries
in our society and asking customers what they need is worrisome
and hectic to the society. One is disturbed the time it takes, as well
as the difficulty it poses to the attendants who work in such places. This
device will enable
the attendants to
see the items demanded
from any table by looking on a screen thereby reducing queue
and saving cost.
1.3 JUSTIFICATION FOR THE PROJECT
It has been observed that the usual
practice of attendants enquiring from customers their needs before services are
rendered in the hospitality industries are associated with many problems which
includes:
Queue.
Increased
cost (labour cost).
Loss of
customers due to dissatisfaction in service.
Time
wastage.
1.4 SCOPE
OF THE WORK
This
wireless menu selection system prototype is intended to request for x; y; z;
services from customers in an organization. This research work aimed at
constructing effective software and hardware for wireless menu selection system
specifically has the following objectives: To produce a device that:
v
Saves the time of going from one table to
another to ask customers of their needs.
v
Has program control remote, which helps to
eliminate the use of switches and running of cables.
v
Create a system that can reduce sensitivity and
ensure integrity of the complete microprocessor system during all forms of
environmental stress (shock, transient noise) etc.
v
Removes queues associated with services in
organizations and the hospitality industries.
The
hardware construction is microprocessor- based.
1.5 SIGNIFICANCE
OF THE STUDY
The
significance of this research work is that the system designed can be useful in the hospitality industries, cafeteria and large or small
fast food
joints. The merits are:
Time:
This work saves the time it takes to go from one table to another to know
customers need.
Cost:
The system reduces cost as the numbers of attendants needed are minimal.
Queues
are greatly reduced thereby enhancing customer’s satisfaction.
This
work can be used for academic purpose
Generation
of fund: When an organization makes greater profit, they tend to pay larger tax
to the government.
However,
the use of this equipment reduces the number of attendants required is the industry.
