Microcontroller-Based Generic Remote Process Monitoring System Using Fully Expanded State Transition Table

Abstract

This work proposes the development of a generic microcontroller–
based monitoring system which can be applied to any process control
system. It was successfully accomplished using cost reduction
techniques. Microcontroller was used to control the example
processes by using the technique of ROM based fully expanded table.
The process of emulating AT commands using microcontroller was
also demonstrated. This approach can be applied to many other
monitoring systems. It is adaptable for use in a wide range of
applications and yet it is simple and does not need a complicated
process of customization. A new application can use the software
simply by replacing the state transition table (STT) with that of the
new application through a Graphical User Interface (GUI) module. As
a result, the developed system can be plugged into many applications
that require remote mobile access. It serves as an effective front-end
communication interface that provides wireless access to data in real
time from anywhere.
