Method and apparatus for equipment health monitoring
First Claim
1. A computer implemented method of monitoring the health of a system comprising:
- storing a first plurality of system data associated with at least one steady state capacity level in a memory, wherein the memory is accessible by a building supervisory controller;
obtaining a second plurality of system data indicative of system conditions during system operations;
identifying from the second plurality of system data that the system was operating at a normal operating level during at least one sample window of the system operations;
associating the normal operating level of the at least one sample window with the at least one steady state capacity level;
retrieving first health data for parameters associated with a first health condition from the first plurality of system data;
retrieving second health data for parameters associated with the first health condition from the second plurality of system data that were obtained during the at least one sample window;
comparing the first health data with the second health data;
determining by the building supervisory controller if the second health data is indicative of a health condition based upon the comparison; and
displaying the results of the determination.

Abstract
The present invention provides for monitoring the health of a system. In one embodiment, a method includes storing benchmark data in a memory, storing a second plurality of system data indicative of system conditions during system operations, determining from the second plurality of system data that the system was operating at a steady state capacity level during at least one sample window of the system operations, associating the steady state capacity level of the at least one sample window with the benchmark data, retrieving first health data for parameters associated with a first health condition from the first plurality of system data, retrieving second health data for parameters associated with the first health condition from the second plurality of system data that were obtained during the at least one sample window, comparing the health data and determining if the second health data is indicative of a health condition.
