Abstract: Due to the isolation between the state monitoring, the fault diagnosis and the maintenance management at present, they could not function very well. To deal with this problem, a strategy for Condition-Based Maintenance (CBM) which combined off-line and on-line monitoring and diagnosis was proposed. The working model for CBM was set up. The function model of equipment maintenance management system based on condition monitoring and fault diagnosis was constructed by IDEF. The maintenance management system based on state monitoring and fault diagnosis was developed through network, computer and database technologies. The proposed system could be served as an effective management tool for implementing CBM in power plants.
