摘　　要：高速列车是高铁完成运输使命的核心装备和直接载体,绝大多数高铁重大事故和安全隐患均发生在列车运行中,高速列车在途安全和运用效率是高铁安全保障和运维技术体系构建的核心目标,也是全球高铁领域科技竞争高地。本文介绍了项目组在列车在途服役状态全息化感知和精确辨识、故障在途诊断和预警、预测性精益维修和高性能车地数据传输等瓶颈技术取得的一些重要进展。High-speed trains are the core equipment and direct carrier for the high-speed rail to accomplish the transportation missions.As most major high-speed rail accidents and safety hazards occur during train operation,the en-route safety and operation efficiency of high-speed trains are the core goals when establishing the teclmical systems for high-speed rail safety and operation and maintenance,and is a field of tech competition in high speed rail worldwide Tliis paper introduces some important advances made by the project team in the holographic perception and precise identification of the trains in service status,en-route fault diagnosis and early warning,predictive lean maintenance,and high-perfonnance vehicle-to-ground data transmission.
