MULTIPLE ASPECT OPERATOR INTERFACE FOR DISPLAYING FAULT DIAGNOSTICS RESULTS IN INTELLIGENT PROCESS CONTROL SYSTEMS

摘要

In a fault diagnostic system an operator interface (25, 30) simultaneously displays an operations hierarchy (60) and a components hierarchy (50) in two separate windows (200, 210). The display system is used with a model-based diagnostic system (10, 95) that monitors operational parameters of an industrial process (20). The diagnostic system (10, 95) identifies possible failure source components in the industrial process (20) an the display system (25, 30) uses these diagnostics to display the most interesting portions of the operations hierarchy and the components hierarchy. The most interesting node, to be displayed with its subtree, is defined as the node at the lowest level of the hierarchy that is both a fault source and that has more children than other fault sources at that level.
