摘要： A system to monitor the health of the structure, program product, and associated methods are provided. The system can include multiple health monitoring sensor nodes positioned to monitor parameters of a portion of the body of the structure. Sensor elements of the sensor nodes are spatially positioned along the body of structure at related or complementary locations to form a special correlative relationship between sensor nodes. The system can also include a data collector having a transceiver positioned to gather sensed parameter data from each of the sensor nodes, and a central computer including in memory, parameter process program product adapted to analyze the sensed parameter data, correlate the sensed parameter data to infer a state of health of the structure responsive to the correlation, and to detect or otherwise determine a type, severity, and/or location of damage to or incipient failure of the structure.

摘要： A processing system for clearance estimation in a rotating machine includes one or more sensors and one or more digital signal processors for calculating the estimated clearance. The processing system may include techniques for obtaining real-time clearance estimates and techniques for obtaining averaged clearance estimates. Aspects of the processing system may also include a method of switching between real-time clearance estimates and averaged clearance estimates depending on the operating conditions of the rotating machine. Other aspects of the processing system include the use of two digital signal processors: a first digital signal processor configured to receive signals from a clearance sensor and perform a first set of high speed processing tasks, and a second digital signal processor configured to receive signals from the first digital signal processor and perform a second set of lower speed processing tasks.

摘要： Self-calibration of a multiple channel clearance sensor system, which in one embodiment includes at least one sensor for measuring at least one clearance parameter signal between a stationary object and a rotating object of a rotating machine. The sensor output is processed as a clearance parameter by an offset correction section configured to determine an offset error in the clearance parameter signal which is used by a level shifter. The level shifter is also switchably coupled to the clearance parameter signal wherein the output of the level shifter, which may be amplified and digitally converted, is processed by a signal level analyzer to determine a channel gain signal.
