列车运行控制系统车载设备PHM实施方案

Implementation scheme of prognostics and health management for on-board equipment of train control system

列车运行控制系统车载设备(简称:列控车载设备)是一种高度集成化的电子设备,针对其维护难点,提出将故障预测及健康管理(PHM,Prognostics and Health Management)技术引入列控车载设备维护。文章基于设备全生命周期管理理念,提出列控车载设备PHM实施方案,将设备功能需求与维修需求融合一体,使列控车载设备PHM系统的研发与列控车载设备的升级改造相协调,通过列控车载设备加装升级、数据处理与分析系统建设,在完善列控车载设备BIT和数据采集与分析功能的基础上,构建列控车载设备健康评估系统。并制定了列控车载设备PHM实施计划,稳步推进相关设备研制及系统研发与建设工作,使维修保障部门能够在列控车载设备健康评估系统支持下高效协同工作,实现故障处置闭环管理,推动列控车载设备维修转向视情维修模式。

The onboard equipment of the train operation control system is a highly integrated electronic device.To address the difficulties in its maintenance,it is proposed to introduce fault prediction and health management(PHM)technology into its maintenance.Based on the concept of equipment lifecycle management,this article proposes an PHM implementation scheme of train control on-board equipment.Through integrating equipment functional requirements with maintenance requirements,the research and development of PHM system for train control on-board equipment is coordinated with the upgrading and renovation of train control on-board equipment.After the upgrading and renovation of train control on-board equipment and the construction of data processing and analysis systems,the health assessment system for train control on-board equipment is built on the basis of improving the BIT and data acquisition functions of train control on-board equipment.Then,a implementation plan is formulated to steadily promote the development of related equipment and the construction of those systems.With the support of the health assessment system for train control on-board equipment,the maintenance support departments can work efficiently and collaboratively and enable closed-loop management of fault disposal,pushing forward the maintenance of onboard train control equipment to shift to On-Condition maintenance mode.
