Method Of Identifying Abnormal Operation Of A Machine And An Apparatus Therefor

摘要

A method of identifying abnormal operation of an industrial machine includes the step of determining statistical parameters from a plurality of samples of characteristic parameter(s) of known similar industrial machines in normal operation and storing them, the statistical parameters defining a statistical range of values of the characteristic parameter(s) for normal operation of the industrial machine. The characteristic parameter(s) of a machine being monitored are sampled and a determination ( 702 ) is made as to whether sampled characteristic parameter(s) falls within the statistical range of values for normal operation of the industrial machine. If the sampled characteristic parameter falls outside the statistical range of values for normal operation of the industrial machine an alarm signal is generated ( 706 ).
