Paper Abstract

Widespread acceptance of Condition Based Monitoring (CBM) systems has been hampered by, among other things, high costs and inaccurate diagnostics. The advent of new methods for signal processing, local wireless networks, and an industry standard architecture is an opportunity to develop low cost, reliable, practical health monitoring systems. We will discuss the signal processing issues that contribute to poor performance and how new algorithms can provide near optimum detection and recognition of broad-band signals in nonideal, changing, noise. We will then discuss the ONR sponsored Open Systems Architecture (OSA) and how that provides a common operating protocol for health monitoring systems. The heart of the OSA/CBM system is protocols for communication among the hardware and software components of a generalized CBM system which allows rapid and easy integration of specialty components. Finally, we will discuss the impact of several new technologies, including local wireless networks. For example, in many potential installations, almost 90% of the cost of installation is the wiring from the sensors to the processing units. By processing the raw data at the sensor and using a local wireless network to move data and monitor the CBM system itself, the cost of health monitoring can be dramatically reduced.
