Abstract

A system for transmitting data from a rotating component includes sensors on the rotating component, wherein each of the sensors detects at least one characteristic of the rotating component and transmits a signal reflective of the characteristic. Data slip rings are in communication with the sensors, and a signal conditioning circuit between the sensors and the data slip rings converts each of the signals from the sensors into a digital signal. A method for transmitting data from a rotating component includes sensing a characteristic of the rotating component using sensors and generating a signal from each of the sensors reflective of the characteristic of the rotating component. The method further includes converting each of the signals to a digital signal and transferring each of the digital signals from the rotating component through a plurality of data slip rings.

Description

technical field [0001] The present invention generally relates to systems and methods for communicating data from rotating assemblies. In particular embodiments, systems and methods may provide power to sensors on rotating assemblies. Background technique [0002] Many machines contain rotating components. For example, wind turbines, gas turbines, steam turbines, pumps, fans, generators, engines, and other forms of commercial equipment often contain shafts, blades, and other rotating components. It is known in the art to mount one or more sensors on a rotating assembly to measure various characteristics of the rotating assembly to control, monitor, and / or improve the operation of the rotating assembly. For example, sensors that measure temperature, velocity, stress, strain, vibration, and / or other characteristics of rotating components may allow early detection of abnormal conditions, adjustments to repair or maintenance schedules, and / or other actions to improve operation...
