CHAPTER ONE

1.0     INTRODUCTION

We all know that micro-processor have became one of the must widely used technology in the field of computing information processing and management real-time processing, telecommunication e.t.c.

Briefly, some of the most impressive change which the microprocessor revolution has liquidifies are:-    

Low cost of computing machinery and micro-processor based device

Tremendous improvement in the system reliability and some times reduction in the size of such systems.

The accuracy and consistency of such system when properly programmed requires no over emphasis.

Increased speed of computation leading to higher through put.

These important attributes possessed have led to their wide application in so many area of life from computer system, home appliance to serious industrial and other office machineries.

An automated luggage billing device is an instrument, which is used in determining the weight of object placed on its load cell. This device may be constructed in such a way that it could be connected to a computer system for direct weight transmission and the whole system may become computerized using an effective software system. The system consists of a strain-guage transducer on which the luggage is placed. The guage voltage is proportional to weight placed on it. The voltage is fed directly to an ADC means (Analog-Digital converter) which in turn converts the signals to corresponding binary code and presents it via register. The binary coded data is usually received by the decoder/demultipler as signals from the input lives of the internal expansion.

Having known how an automated billing device works, a computer software-base luggage billing system for parcel and luggage section of Sosoliso air line is a software which may implement such device. It has been designed to accept weight of the luggage, the distance (km) between location and destination in order to produce a comprehensive bill which could be stored and manipulated according to users choice.
