摘　　要：动车组滚动轴承故障轨旁声学诊断设备(TADS,Trackside Acoustic Detection System)能够实现动车组滚动轴承早期损伤的及时发现,为动车组运行安全提供了有力的保障。由于具有多次监测综合分析的诊断特点,单点部署的TADS设备在故障的快速准确判定上难以满足运用需求。为此,基于既有地对车安全监测联网应用的技术经验,针对动车组TADS设备特点及业务运用需求,研究了动车组滚动轴承故障轨旁声学联网监测应用技术,构建了两级部署、多级应用的总体联网技术方案,提出了集中统一的数据接入规范,设计了全流程闭环管理的监测故障报警处置流程,实现了动车组滚动轴承故障的集中监测、联网诊断及综合管理,为有效保障动车组运行安全提供了技术支持。TADS(Trackside Acoustic Detection System)can realize the early damage detection of EMU rolling bearings,which support the EMU running safety effectively.Due to the characteristics of multi-point comprehensive analysis,single-point TADS is difficult to achieve fast and accurate diagnosis of faults.In this paper,based on the equipment characteristics,application requirements,and the existing technical experience,we research the network monitoring technology of TADS,designed a scheme of multistage networking,proposed a unified data access specification,designed a fault closed loop management process,and implement an application system.The system realizes centralized monitoring,networked diagnosis and integrated management of EMU rolling bearing faults,provides effective technical support for ensuring EMU operation safety.
