THE DESIGN AND IMPLEMENTATION OF A SOFT-WARE-BASED LUGGAGE BILLING SYSTEM FOR AN AIR LINE. A RESEARCH PROJECT MATERIAL ON COMPUTER SCIENCE
Instruments used for weighing are found in many organizations at the sea and airports for weighing of luggages, at the post office of Sosoliso for weighing and billing determination of items.
Normally these organizations make use of ordinary bulky scales in analog form. The problems with these techniques are; the bill of a read weight of item and inefficiency.
The aim of this project is therefore to design, develop and implement a viable software system that may be modified to read analog signals translated by Analog-Digital-converter (ADC). The designed system accepts unit weight of items and rate (depends on the distance), computes bills and generates a comprehensive airbill for parcel/luggage section of Sosoliso airline.
The system is expected to be very fast in computation precise in bill determination, flexible, easy to read and has storage facilities. It is intelligent and therefore can be easily adjusted and adapted to suit other applications not incorporated in this design by hardware expansion and software modification.
A through description of the hardware design and requirement of an automated luggage weighing device which may implement the developed software system has been given as a stand point for further research.
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:-
Ø Low cost of computing machinery and micro-processor based device
Ø Tremendous improvement in the system reliability and some times reduction in the size of such systems.
Ø The accuracy and consistency of such system when properly programmed requires no over emphasis.
Ø 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.
