NI expands capabilities in machine prognostics and health management
National Instruments has introduced the Watchdog Agent Prognostics Toolkit for NI LabVIEW system design software to expand the capabilities of LabVIEW in machine prognostics and health management (PHM) applications.
The product is the result of a collaboration between NI and the National Science Foundation's Industry/University Cooperative Research Center at the University of Cincinnati.
The toolkit serves demand for monitoring and reporting the health status of machines, structures, components and systems.
This is said to provide an easy-to-use solution for predictive maintenance and prognostics.
The ready-to-run prognostics solution can increase engineering efficiency for developing any PHM application.
It employs the signal processing capabilities of LabVIEW and the analysis of the NI Sound and Vibration Measurement Suite.
Algorithms include logistic regression, statistical pattern matching, a self-organising map, a support vector machine and a Gaussian mixture model.
Engineers can use these to create machine and component status descriptors of operating states and failure modes, converting multiple field sensory readings into summarised health information values for efficient monitoring.
The toolkit also includes a health radar chart that displays organised health values of multiple machine components on a single display.
In addition to integrating with the Sound and Vibration Measurement Suite, the Watchdog Agent toolkit can read history data collected from the NI measurement hardware including NI CompactRIO, CompactDAQ, PXI and PCI.
It also integrates with the IOtech eZ-TOMAS Technical Data Management Streaming (TDMS) data plug-in, vibDaq from CalBay Systems or any other sensory data acquisition systems based on NI TDMS data files.
