Beschreibung
Zusammenfassung:	The present invention relates to a monitoring parameter selection method based on failure characteristic analysis. The method mainly includes the following steps: (1) determining a to-be-analyzed failure mode set according to system failure attributes (severity, failure rate, transmission intensity); (2) performing expanded failure modes, mechanisms and effects analysis (FMMEA) according to the to-be-analyzed failure mode set; and (3) determining a system monitoring parameter set according to the result of the extended FMMEA. System failure propagation characteristics and failure evolution characteristics are considered in the method based on the existing monitoring parameter determination method, thereby enabling finally obtained monitoring parameters to be more practicable in engineering.
