Equipment health monitoring architecture for fleets of assets
First Claim
Patent Images
1. An asset fleet health monitoring system, comprising:
- a sensor data feed module for providing multivariate sensor data from a plurality of fleet assets;
a database for storing empirical models of assets in the fleet;
an estimation engine disposed to generate estimated sensor values and residuals in response to receiving from the data feed an observation of multivariate sensor data for an asset in the fleet, using a corresponding empirical model for the asset stored in said database;
an incident diagnostics engine module responsive at least to said residuals to determine whether an incident should be registered for said asset; and
a graphical interface module having a hierarchical fleet view of the health status of all assets and an exception-based view of all assets having registered incidents.

Abstract
A system and method for use in monitoring equipment condition employs an empirical model, a rules engine, incident generation and resolution logic, a display interface, and a messaging capability for interacting with other systems. The empirical model uses similarity-based modeling to generate equipment instantiation-specific models with high fidelity. Residuals are generated by comparison of model estimates with actual current parameters, and rules are used to identify diagnostic incidents from patterns in the residuals, actual values, estimates, and alerts on residuals.
