Introduction
Preview
The
project was first conceived along the lines of a goal that is simple to
understand and yet a challenge to implement. Other factors, which influenced the
choice of the project, include the application of the UART for remote
operational environment. Further, it enabled me to apply the knowledge gained
through the Engineering Council Examination and the skills acquired during my
work at the field of Electronic Engineering.
Objective
The
project is to read a number from a terminal, which is located at a remote point.
Subsequently, the numbers is validated by a database, which is places at central
location, and relay a message to remote terminal depending on the data it
received. The objective has been reached.
Methodology
The project design was carried out in
two phases. Phase I involved in the design of the RIVD and PCB. For this a wide
variety of remote interfacing products and associated literature were thoroughly
studied. Most importantly, the data sheets of communication ICs collected from
respective semiconductor manufacturers and further invited them for their
suggestion for the improvement of the project. First, all the individual events
were modularized to form the complete design and layout the basic architecture
of RIVD. Then each module was tested in account of its performance and was
linked to successive event and was tested again for overall performance. Once
this breadboard design part was accomplished, PCB design and other electrical
connections together with its associated accessories were accompanied
The phase II of the project was to write
programs in C and was scrapped and Visual Basic
program was written to take its place for RIVD. The programs were checked
manually with test data before the full implementation. Later, they were
complied and tested again to verify the 100% accuracy in performance. This work
was completed at week 11, which left one week to adjust and further improvement.
