Intelligent O&M Technology of EMUs Based on Prognostics and Health Management
Prognostics and Health Management(PHM)technology is a critical component in establishing a precision-based O&M system for EMUs.This technology is essential for enhancing lifecycle management and advancing manufacturing and repair processes of EMUs.Through the analysis on O&M requirements of EMUs,this paper proposes the intelligent O&M objectives of EMUs based on PHM technology,as well as the system design architecture incorporating functions such as condition monitoring,fault prediction,health assessment,decision support and O&M analysis;and constructs a PHM-based standardized system for intelligent O&M of EMUs.The study also explores aspects such as the data lifecycle of EMUs,the development of PHM models,high-frequency streaming computation methods,unified management of heterogeneous models,and PHM-driven O&M production organization technologies.The PHM-based intelligent O&M system has been implemented across the railway network,achieving seamless information flow throughout the entire process of monitoring,decision-making and execution.
