RANGED FAULT SIGNATURES FOR FAULT DIAGNOSIS

摘要

A method and apparatus for diagnosing faults . This defect is detected . That one or more process variables that contributed to the fault are determined. One or more process variables each relative contributions is determined. Fault signatures is made a determination as to whether a defect and matching , the relative contributions of the one or more process variables is made when there are matched within the relative contribution range of a fault signature matching . Each fault signature is associated with at least one fault class .
