MICRO PROCESSOR BASED COLD STORAGE PROCESS INSTRUMENTATION CONTROL

Abstract

The main thrust of this work is in the direction of development of instrumE ntation system to measure and control different dynani c variables in a given cold-storage plant using Intel 8485 microprocessor. It is proposed to study the cold-storage plant thoroughly with a view to understand its -process dynamics and to develop microprocessor controller using Intel 8C85, The characteristics and the performance of the transducers in sensing the different process variables (encountered in Bold--storage plant) and signal conditioning them, to be compatiable with a microprocessor controller, is a very important area of this work. Development of microprocessor based digital instru-mentation, for displaying and controlling the different variables, also forms an equally important area of this work.
