摘要随着我国城市化的不断推进，城市轨道交通得到了迅速发展。轮对作为城市轨道交通车辆重要组成部件，安全性日益受到广泛重视，其尺寸、磨损情况和故障状态需要进行记录、趋势分析及预估。能自动化处理分析轮对信息的城市轮对管理信息系统，其功能也正得到不断地拓展。本文在国内外研究现状的基础上，增加了一些管理信息系统的关键模块，包括给出轮对数据的磨损趋势及规律的分析示例，应用到管理系统后可实现分析结果的自动输出；划分轮对故障风险等级，设计硬件警报流程以及得出镟修周期优化的方案。初步完成了轮对管理系统一些关键智能模块的拓展。62985

Title Wheelsets Management Information System of Urban Rail Transit Vehicles ——The Development of Key Intelligent Modules 

Abstract With the continuous advance of China's urbanization, urban rail transit has been developing rapidly. Wheelsets act a key component of urban rail transit vehicles, whose security increasingly widespread attention. Its’ dimensions, wear data and fault status need to be recorded, analysis and forecast. While Wheel information can be automated processing and analysis on wheelsets management information system，the functions of the wheelsets management information system are being constantly expanded. This paper based on research status at home and abroad, adds some key modules to the management information system, including giving an example how to analyze wheel wear data and trend, applied to the analysis results, system can achieve automatically outputs; piding the fault state into some grades; a design of a hardware alarm process; raising an optimization of the wheel re-profiling cycle. Some key intelligence modules of the wheelset management system are completed initially.
