APPARATUS AND METHOD FOR MONITORING HEALTH OF ARTICULATING MACHINERY
First Claim
1. A method for acquiring repeatable and trendable performance data for monitoring the health of an articulating machine, the method comprising:
- (a) storing in memory one or more motion predicate values, each indicating a motion condition to be achieved as a predicate to analysis of performance data as the machine performs one or more prescribed motions;
(b) collecting performance data from a plurality of sensors attached to a plurality of components of the machine as the machine is operated to perform work;
(c) determining whether one or more motion conditions are being achieved for a particular one of the one or more prescribed motions based on comparing the performance data to the one or more motion predicate values;
(d) calculating one or more analysis parameter values that are indicative of the health of the machine using performance data collected while the one or more motion conditions are being achieved for the particular prescribed motion; and
(e) repeating one or more of steps (b) through (d) until analysis parameter values have been calculated for the one or more prescribed motions.

Abstract
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.

23. A method for acquiring repeatable and trendable performance data for monitoring the health of an articulating machine that performs one or more prescribed motions while performing work, the method comprising:
-
(a) collecting performance data from a plurality of sensors attached to a plurality of components of the machine as the machine is operated to perform work; (b) determining, based on the performance data, that the machine is performing a prescribed motion that repeats during operation of the machine; (c) selecting segments of the performance data that were collected while the machine was performing the prescribed motion that repeats during operation of the machine; (d) determining that a sufficient number of segments of the performance data have been selected to calculate one or more analysis parameter values that are indicative of the health of the machine; (e) calculating the one or more analysis parameter values when a sufficient number of segments have been selected; and (f) repeating one or more of steps (a) through (e) until analysis parameter values have been calculated for the one or more prescribed motions. - View Dependent Claims (24, 25, 26)
