| 201 | Methods for using digitized sound patterns to monitor operation of automated machinery | US14870256 | 2015-09-30 | US09945755B2 | 2018-04-17 | Blake Pluemer |
| 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. | ||||||

| An apparatus for acquiring repeatable and trendable performance data for monitoring the health of an articulating machine includes sensors, a programmable logic controller, a machinery monitoring system, and a display device. The sensors collect performance data as the machine performs prescribed motions. The programmable logic controller includes memory for storing motion predicate values that indicate motion conditions to be achieved as predicates to analysis of performance data as the machine performs the prescribed motions. A processor in the programmable logic controller compares the performance data to the motion predicate values to determine whether the motion conditions are being achieved as the machine performs the particular prescribed motion. A processor in the machinery monitoring system calculates analysis parameter values that indicate the health of the machine. These calculations are made using performance data collected while the motion conditions are being achieved. The display device prompts an operator to operate the machine to perform each of the prescribed motions until data has been collected for the prescribed motions. | ||||||

| 207 | Processing machinery protection and fault prediction data natively in a distributed control system | US14808418 | 2015-07-24 | US09727050B2 | 2017-08-08 | John W. Willis; Deane M. Horn; Michael D. Medley; Richard W. Kephart; Kevin D. Steele |
| A vibration data acquisition and analysis module is operable to be inserted directly into a distributed control system (DCS) I/O backplane, so that processed vibration parameters may be scanned directly by the DCS I/O controller. Because the process data and the vibration data are both being scanned by the same DCS I/O controller, there is no need to integrate numerical data, binary relay outputs, and analog overall vibration level outputs from a separate vibration monitoring system into the DCS. The system provides for: (1) directly acquiring vibration data by the DCS for machinery protection and predictive machinery health analysis; (2) direct integration of vibration information on DCS alarm screens; (3) acquisition and display of real time vibration data on operator screens; (4) using vibration data to detect abnormal situations associated with equipment failures; and (5) using vibration data directly in closed-loop control applications. | ||||||
