Architectural design of distributed operation monitoring systems

This paper presents an architectural design of distributed information systems used for monitoring operations of gas turbine power generation systems. The software architectural design logically uses a star topology that connects local operation monitoring systems to a central operation monitoring system. The systems are composed in accordance with the concept of three tier model on basis of COM technologies. It is argued that asynchronous and synchronous communication mechanisms are required to for different data transmission scenarios. Finally, COM+ services are implemented to support object pooling, transaction coordination and security control.
