铁路轨道状态分析信息系统设计与实现

研究了轨道状态分析信息系统的设计与实现方法。利用检测数据作为分析轨道状态的出发点,研究轨道状态的变化趋势,在分析国内现有铁路工务管理系统中存在的数据资源分散、忽视历史数据积累等问题的基础上,阐述了构建铁路轨道状态分析信息系统的可行性和必要性,并采用数据仓库技术和地理信息系统(GIS)技术,从空间和时间两个维度分析数据,提出了建立轨道状态预测模型的趋势分析法。笔者研究的核心内容是如何在整合各类轨道动、静态检测数据及铁路运营数据的基础上,建立轨道状态预测模型,为掌握及预测轨道状态变化趋势提供可靠的分析工具。

Design and Realization of Analytical Information System for Railway Track State

The design and realization of analytical information system for railway track state is studied.The data measured are used to analyze the changing trend of the track.The current problems of the data resource are rather scattered and historical data neglected.The feasibility and necessity to construct an analytical information system is probed into in detail.By using the database technology and Geography Information System(GIS),the trend analysis method of track state prediction model is put forward from the analytical data of space and time dimensions.The core content is to establish the prediction model of track state based on integrating the dynamic and static data measured as well as railway operation data providing a reliable analytical tool for mastering and forecasting the changing trend of track state.
