Optimization method for adaptive sensor reading scheduling and delayed alarm evaluation in real-time diagnostic systems

摘要

An optimization method is used in a real-time diagnostic system that monitors alarm sources and detects possible sources of failure in an industrial process. When the diagnostic system detects one or more alarms, it determines which components are likely sources of failure. The system determines the level of criticality of certain other, currently off-line, alarms sources and schedules the off-line alarms for evaluation according to their levels of criticality. The system refines its analysis of likely sources of failure by evaluating the status of the previously off-line alarm sources Those previously off-line alarm sources are added to the grouping of possible sources of failure prior to repeating the evaluation process. The evaluation process is repeated, with the analysis of likely causes of failure being continually refined.
