Finger Printing: What is it?
Fingerprinting is a pattern recognition technique
that when enabled with CogniSim can allow mechanical behavior to be measured and
compared against a baseline fingerprint. Examples where fingerprinting could be
beneficial include, detection of abnormal behavior before catastrophic failure,
or the sensing of paper texture surface quality, or any other distinguishable
vibrational characteristics of an application.
The unique nature of CogniSim allows the controller
to extract information about shaft disturbances that cannot be acquired by any
traditional system, and if properly utilized can provide a fingerprinting
capability that can be used to monitor the state of the motor and mechanical
system over time.
This capability can be developed into a monitoring
tool that will provide a more flexible approach to maintenance planning and
execution based upon changing trends in the motor/mechanical systems operating
signature.
Since CogniSim samples data at very high speeds, it
generally allows the CogniSim controller to provide a natural capability as a
spectrum analyzer, allowing the fingerprinting capability to be readily
realized. |
