Methods for using digitized sound patterns to monitor operation of automated machinery
First Claim
1. In a corrugator that converts paper webs into corrugated paperboard sheets, a method for monitoring operation of corrugator machinery, the method comprising:
- with a sensor, converting an actual sound pattern generated by an operating corrugator machine into an audio signal;
receiving the audio signal with a controller, and with the controller, digitizing the audio signal to create a real-time acoustic fingerprint unique to the actual sound pattern;
with the controller, accessing a reference database in a storage system, the reference database containing a plurality of stored acoustic fingerprints, each stored acoustic fingerprint in the plurality of stored acoustic fingerprints representing a unique sound pattern associated with a particular operating condition of the corrugator machine;
comparing the real-time acoustic fingerprint to the plurality of stored acoustic fingerprints in the reference database with the controller; and
in response to detecting a match between the real-time acoustic fingerprint and one of the plurality of stored acoustic fingerprints with the controller, generating an output command with the controller, which output command is associated with the particular operating condition in the storage system;
receiving and carrying out the output command at a component of the corrugator machine.

Abstract
In an operating machine, one example of a method for monitoring operation of operating machinery includes converting an actual sound pattern generated by the machine into an audio signal and digitizing the audio signal to create a real-time acoustic fingerprint unique to the actual sound pattern. A reference database contains a plurality of stored acoustic fingerprints, each stored acoustic fingerprint in the plurality of stored acoustic fingerprints representing a unique sound pattern associated with a particular operating condition. A controller compares the real-time acoustic fingerprint to the stored acoustic fingerprints in the reference database and generates an output in response to detection of a match between the real-time acoustic fingerprint and one of the plurality of stored acoustic fingerprints. One example of the machine is a corruptor machine that converts paper webs into corrugated paperboard sheets.

15. In a corrugator that converts paper webs into corrugated paperboard sheets, a method for monitoring operation of corrugator machinery, the method comprising:
-
(a) with a sensor, converting an actual sound pattern generated by a machine into an audio signal; (b) receiving the audio signal with a controller, and with the controller, digitizing the audio signal to create a real-time acoustic fingerprint unique to the actual sound pattern; (c) with the controller, accessing a reference database in a storage system of the controller, the reference database containing a plurality of stored acoustic fingerprints, each stored acoustic fingerprint in the plurality of stored acoustic fingerprints representing a unique sound pattern associated with a particular operating condition of the machine; (d) comparing the real-time acoustic fingerprint to the plurality of stored acoustic fingerprints in the reference database with the controller; (e) in response to detecting a match between the real-time acoustic fingerprint and one of the plurality of stored acoustic fingerprints generating a corrective output command with the controller, which corrective output command is associated with the particular operating condition in the storage system; (f) receiving and carrying out the corrective output command at a component of the machine; and (g) thereafter repeating steps (a) through (f) until the real-time acoustic fingerprint matches a stored acoustic fingerprint representing a unique sound pattern associated with a correct operating condition of the machine. - View Dependent Claims (16, 17, 18, 19, 20)
