On-Line Detection of Key Equipment Failure (105)
Problem: Develop a reliable, on-line method to monitor manufacturing equipment for critical component failure
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Integrated Systems
PNNL Solution:
- Determined acoustic signatures that can detect key component failure
- Designed system using commercial sensors with PNNL electronics, signal analysis, and controls
- Successfully integrated system into operating industrial production line
- Transferred technology to commercial source
- R&D 100 Award winner in 2000
- FLC Award winner in 2001
Capabilities Employed to Meet Client Needs: Production plant testing to determine broad spectral acoustic signatures and levels associated with normal operation; testing to determine acoustic signatures associated with equipment failure; analysis of broad spectrum acoustic data to determine spectral signatures that allowed reliable failure detection; transducer selection; electronics design; signature analysis development based on exploitable acoustic signature; prototype equipment development for on-line equipment monitor; mechanical design for instrument housing and plant installation; equipment installation on production line; on-line testing to verify operation with low false alarms and reliable failure detection; technology transfer to selected vendor.
