Computer Application Onboard a Vessel - Distributed Digital Control System

摘要

A control system comprises interconnected elements or devices which interact in such a way as to maintain or affect, in a prescribed manner and that too without human intervention, some conditions of a machine forming a part of another larger system. This paper describes a microprocessor-based, computer-oriented control system where all operations including navigation and propulsion controls of a ship have been decentralized and managed from the field controller command centres. All parameters, data and communications within the ship's sub-systems are controlled by the decentralized field control stations with data being acquired, processed and stored locally for onward transmission to the command centres.
