Abstract: To satisfy the demands of fault forecasting in Maintenance, Repair and Overhaul (MRO) service, an intelligent inspection system based on equipment status monitoring was designed. Data acquisition and localization were realized by data collection nodes. Then wireless communication was used to transmit data.Intelligent sensor network node was designed based on 8051 series Single Chip Microcomputer (SCM). A description algorithm for equipment performance degradation based on Wavelet Packet Decomposition (WPD) and Support Vector Data Description (SVDD) was proposed. Reliability and effectiveness of the proposed system were verified by applying to steel continue casting line.

Key words: steel, continuous casting equipment, inspection system, maintenance, repair and overhaul, wavelet packet decomposition, support vector data description, fault diagnosis
