An Internet-based Machinery Health Monitoring System

摘要

An Internet-based machine condition monitoring system has been developed that allows off-site maintenance personnel to access machinery diagnostic information in real-time. The Internet provides an inexpensive vehcile for the collection and assessment of condition data from machiens in distant plants that leads to improved maintenance scheduling. The On-line health monitoring system is designed to efficiently and reliably transfer acquired data to remote server for processing and analysis then publish the results on a secure Web-site on a minute by minute basis. Sophisticated machine condition assessment techniques including sensor validation, statistical trending, and fuzzy logic algorithms are implemented to detect incipient forms of machien performance degradation. An Internet-based conditon monitor for a supercritical steam turbine is presented to illustrate the features, operation, and architecutre of the system.
