Data Acquisition System for Condition-Based Maintenance
First Claim
1. A data acquisition system for monitoring one or more components of rotating machinery, the data acquisition system comprising:
- a plurality of separate sensor modules, each of said plurality of separate sensor modules being associated with one of a plurality of separate components of rotating machinery and configured to detect a parameter associated with a condition of at least said separate respective component and to generate data comprising a representation of said condition of at least said separate respective component based, at least in part, on said detected parameter; and
a data bus configured to couple each of said plurality of separate sensor modules to a server, wherein said server is configured to provide an estimate of remaining useful life of a selected one of said separate respective components of said rotating machinery to a user based, at least in part, on a representation of a condition of said selected one of said separate respective components.

Abstract
Generally, a system and method consistent with the present disclosure may provide a relatively low cost, relatively robust data acquisition and analysis system useful for condition-based maintenance. The system may be useful for condition-based maintenance in industrial applications, e.g., of equipment and/or machinery. The industrial monitoring system may be used, for example, to monitor a condition of rotating machinery, e.g., a wind turbine. The system and method may include data analysis that may be useful for anticipating a need for maintenance, repair and/or replacement of one or more components.

16. A method of determining an estimate of a remaining useful life of a monitored component of rotating machinery, the method comprising:
-
providing a data acquisition system mounted on rotating machinery, said data acquisition system comprising; a plurality of separate sensor modules, each of said plurality of separate sensor modules being associated with one of a plurality of separate components of said rotating machinery; and detecting a parameter associated with a condition of a selected one of at selected one of said plurality of separate components or a component indirectly coupled thereto and generating sensor output data based, at least in part, on said parameter; analyzing said sensor output data; generating module output data comprising a representation of said condition of said selected one of said plurality of separate components or said component indirectly coupled thereto based, at least in part, on said sensor output data; transmitting said output data to a server, and estimating remaining useful life of said selected one of said plurality of components or said component indirectly coupled thereto based, at least in part, on a representation of a condition of said selected one of said plurality of components or said component indirectly coupled thereto. - View Dependent Claims (17, 18, 19, 20)
