摘要

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.
