PHM技术在京张高速铁路运用检修中的应用研究

Application of PHM Technology in Operation and Maintenance on Beijing-Zhangjiakou High Speed Railway

为提高京张高速铁路精准化、精细化管理和服务水平,保障冬奥会期间动车组安全高效运行,首次在京张高速铁路配属动车组上开展PHM研究和系统应用的先行先试。作为动车组运用检修系统的应用扩展与延伸,PHM系统实现了动车组在途故障的超前预警,视情维修信息可在动车组运用检修系统中进行流程贯通和交互闭环。结合京张高速铁路PHM试点应用情况,从需求分析、总体架构、功能架构、逻辑架构和物理架构等方面总结归纳了动车组PHM技术体系及关键技术。通过PHM系统在京张高速铁路的试点应用,有效提高动车组运行保障能力,提升运用效率和效益,改善运行秩序,为PHM技术在全路范围的应用提供宝贵经验。

To improve the precise and refined management and service level of the Beijing-Zhangjiakou High Speed Railway and ensure the safe and efficient operation of electric multiple units(EMUs)during the Winter Olympics,this paper took the lead in presenting pilot prognostics and health management(PHM)research and PHM system application on the EMUs assigned to the Beijing-Zhangjiakou High Speed Railway.As the expanded application and extension of the EMU operation and maintenance system,the PHM system achieved the advance fault warning for EMUs in transit and the process connection and interactive closed-loop of condition-based maintenance information in the EMU operation and maintenance system.By investigating the pilot application of PHM on the Beijing-Zhangjiakou High Speed Railway,this paper summarized the PHM technology system for EMUs and its key technologies from the aspects of demand analysis,overall architecture,and functional,logical,and physical architectures.The pilot application of the PHM system on the Beijing-Zhangjiakou High Speed Railway shows that this system can effectively elevate the operation guarantee capability,operation efficiency and profit,and operation order of EMUs,and it also provides valuable experience for the application of PHM technology in the whole railway network.
