Real-time video for distributed control systems

摘要

Automation based on distributed control systems (DCS) technology enormously increases the plant supervision capability of a single human. For example, DCSs over broadband networking makes possible the integration and operation of a country-wide electricity generation and distribution system. Out-of plant supervision is, however, more risky due to the impossibility of direct plant observation and exclusive reliance on digital data systems for decision making. This paper describes a distributed system based on CORBA technology to provide real-time visual feedback to operators of such a large supervision system.
