Integration of Diagnosis Techniques
Rolf-Einar Grini, Tor Karstad · 1992
One îf the largest branches in computerised operator support system research for process plants is diagnosis systems. Various techniques arc applied in the diagnostic process. Two diagnosis systems, DISKET and Detailed Diagnosis, applying different techniques have been developed at the OECD Halden Reactor Project. The diversity calls for a way of integrating diagnosis techniques within a framework. Two approaches to this are discussed here; centralised integration and distributed integration. It is required that diagnosis systems being integrated have some sort îf common description of possible diagnoses, represented by diagnosis definitions. Also, the diagnoses must be organised in a tree structure. Centralised integration lets the diagnosis systems work as self-standing systems, sending their output to a central diagnosis administrator which carries out a coordination of the suggested diagnoses. In the distributed integration concept, diagnosis administrators are distributed, each covering a certain process section. The coordination of diagnoses is distributed correspondingly.
