Data acquisition system for condition-based maintenance
First Claim
1. A data acquisition system for monitoring one or more components of a rotating machine having a plurality of separate components, the data acquisition system comprising:
- a plurality of separate sensor modules associated with the machine, each of the plurality of separate sensor modules being associated with a separate respective component of the plurality of separate components of the machine and including;
a sensor configured to detect a parameter associated with a condition of the separate respective component and to provide sensor data based on the detected parameter; and
an interface module coupled to the sensor and configured to receive the sensor data from the sensor and to generate module output data based on the received sensor data, the module output data comprising a representation of the condition of the separate respective component; and
a data bus configured to couple each of the plurality of separate sensor modules to a server, wherein the server is configured to provide an estimate of remaining useful life of a selected one of the separate respective components of the rotating machine to a user.

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.

9. A system comprising:
-
a rotating machine; and a data acquisition system mounted on the rotating machine and configured to monitor components of the rotating machine, the data acquisition system comprising; a plurality of separate sensor modules, each of the plurality of separate sensor modules being associated with one of a plurality of separate respective components of the rotating machine and including; a sensor configured to detect a parameter associated with a condition of the separate respective component and to provide sensor data based on the detected parameter; and an interface module directly coupled to the sensor and configured to receive the sensor data from the sensor and to generate module output data based on the received sensor data, the module output data comprising a representation of the condition of the separate respective component; a data bus configured to couple each of the plurality of separate sensor modules to a server, wherein the server is configured to provide an estimate of remaining useful life of a selected one of the separate respective components of the rotating machine to a user; and a local data concentrator coupled to each of the plurality of separate sensor modules and configured to provide media access control (MAC) for at least one of the separate sensor modules, to transmit commands to at least one of the separate sensor modules, to receive data from at least one of the separate sensor modules and to provide received data to the server via the data bus. - View Dependent Claims (10, 11, 12, 13)
