Virtual instrumentation for integrated bearing condition monitoring

This paper presents the design and implementation of a LabVIEW-based virtual instrument (VI) as part of an integrated bearing condition monitoring system. The VI is capable of performing various test and measurement functions including data acquisition, time and frequency domain analysis, data enveloping, archiving, and management. Furthermore, the VI enables an efficient and user-friendly interface for comprehensive on-line bearing working parameter display, which is of critical importance to bearing health monitoring and diagnosis
