摘要
动车组故障预测与健康管理(PHM)技术是构建动车组精准化运用维修体系的关键环节,对完善动车组全生命周期管理、推进动车组造修水平提升具有十分重要的意义。通过对动车组运维需求分析,提出了基于PHM技术的动车组智能运维目标,以及包含状态监测、故障预测、健康评估、决策支持和运维分析等功能的系统设计架构;构建了基于PHM的动车组智能运维规范体系。对动车组全生命周期数据分析、PHM模型构建、高频流式计算方法、异构模型统一管理、PHM驱动的运维生产组织等技术展开研究。基于PHM的智能运维系统在全路获得了应用,实现了监测、决策与执行全流程信息流通。
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.
