Design and realization of a remote monitoring and diagnosis and prediction system for large rotating machinery 总被引:1,自引:0,他引:1

Traditional on-site fault diagnosis means cannot meet the needs of large rotating machinery for its performance and complexity.
Remote monitoring and diagnosis technology is a new fault diagnosis mode combining computer technology, communication technology,
and fault diagnosis technology. The designed remote monitoring and diagnosis and prediction system for large rotating machinery
integrates the distributed resources in different places and breaks through shortcomings as the offline and decentralized
information. The system can make further implementation of equipment prediction technology research based on condition monitoring
and fault diagnosis, provide on-site analysis results, and carry out online actual verification of the results. The system
monitors real-time condition of the equipment and achieves early fault prediction with great significance to guarantee safe
operation, saves maintenance costs, and improves utilization and management of the equipment. 相似文献

Web-based remote monitoring and fault diagnosis system 总被引:2,自引:0,他引:2

This paper proposes an approved Web-based multilayer distributed software architecture solution for remote monitoring and
fault diagnosis. To tightly integrate legacy monitor systems, a component framework model based on COM has been proposed,
which is very suitable for remote monitoring and fault diagnosis applications. This system has the potential for exchanging
a data acquisition system by using wrapper service components. A mixed thick Web client architecture is proposed to implement
real-time remote monitoring. A Web-based remote monitoring and fault diagnosis system is developed by using modeling technology,
Web application technology, component technology and VME extension for instrumentation (VXI) bus technology, which publishes
a fault diagnosis algorithm package, a basic monitoring package and an advanced analysis package on the Internet. This system
provides authorized users with an effective and instant way to access new monitoring and diagnosis component packages in time.
This paper gives researchers a paradigm to accomplish similar systems. The technique developed may be used for other fields,
such as power engineering, manufacture and transportation system. 相似文献
