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
Shaohong Wang Tao Chen Jianghong Sun 《Frontiers of Mechanical Engineering in China》2010,5(2):165-170
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
