杭州地铁车辆智能运维系统设计与应用

Design and Application of the Vehicle Intelligent Operation and Maintenance System for Hangzhou Metro

针对地铁列车维护成本高、时间窗口少和人为因素影响大等问题,综合应用互联网、大数据与人工智能等技术,文章构建了以“1+4+N体系”为主体结构的杭州地铁车辆智能运维系统。该系统由1个智能运维平台、4个核心子系统(车载监测系统、轨旁监测系统、运维支持系统和智能检修系统)及N个执行模块组成,其利用车载监测设备和轨旁检测设备获取列车运行实时状态信息和故障数据,由运维平台对车辆各系统进行故障诊断和状态监测;并结合智能检修和运维支持系统,实现对车辆的健康管理、检修管理及资产管理,推动了地铁车辆运维从传统故障修、计划修到状态修的维修模式升级。通过该系统的应用,实现了杭州地铁列车的正线运行监视与故障应急处置,提升了车辆列检自动化程度,并为后续检修修程优化奠定了良好的基础。

Aiming at the problems of high cost,small time window and great influence of human factors for metro train maintenance,internet,big data and artificial intelligence technology are used in this paper to construct an intelligent operation and maintenance system of Hangzhou Metro vehicles with"1+4+N system"as the main structure.The intelligent operation and maintenance system is composed of one intelligent operation and maintenance platform,four core subsystems(on-board monitoring system,trackside monitoring system,operation and maintenance support system,intelligent maintenance system)and N execution modules.Its principle is using the on-board monitoring equipments and trackside testing equipments to obtain real-time train running conditions and fault data,and using the maintenance platform to implement metro train system fault diagnosis and condition monitoring.Combined with intelligent maintenance system and maintenance support system,it provides functions of health management,maintenance management and asset management for vehicles,promotes the upgrade of metro train maintenance mode from traditional fault repair,planned repair to state repair.Through the application of the system,normal line operation monitoring and fault emergency handling of Hangzhou Metro trains have been realized,automation degree of daily inspection and maintenance has been improved,and a good foundation has been laid for the optimization of subsequent maintenance and repair process.
