基于多源数据的高铁运营监测数据管理系统研发

Research and Development of High-speed Railway Operation Monitoring Data Management System Based on Multi-source Data

现有高速铁路运营监测数据管理体系主要由数据处理、成果流转、可视化显示、报告输出4个部分构成,信息挖掘与可视化能力弱,缺少与空间地理信息的融合。基于此,采用B/S模式,设计一种包括数据层、服务层和表现层的系统架构,用于运营监测数据的存储、分发和展示;基于ASP.NET和Vue.js框架,实现前后端架构分离;利用Openlayers拓展系统GIS地图可视化与空间分析能力,实现多源数据监测成果维护、监测数据信息挖掘和成果可视化等功能。选取总里程300 km,包含17061个监测点位,11期监测数据的2个运营监测项目作为应用案例,验证系统多层级数据管理体系、数据预检核机制以及地图和分析图表可视化能力。研究表明,该系统通过点位预录入和多坐标系合并导入的方式,有效提高数据入库效率,一张图模块和变形曲线等多张统计图表丰富了成果展示手段,可以有效服务高速铁路运营部门对监测数据的管理与维护。

The existing high-speed railway operation monitoring data management system consists of four main components,which are data processing,result transfer,visual display and report output.The system has disadvantages including weak visualization and data mining,and lacks of the integration with geology information.Based on the fact,a system architecture was built by using the B/S mode,which included data layer,service layer,and presentation layer,for storage,distribution,and display of operation monitoring data.The architecture achieved front-end and back-end separation using the ASP.NET and Vue.js framework.Aiming to enhance the system's GIS map visualization and spatial analysis capabilities,the highspeed railway operation monitoring data management system incorporated with the Openlayers which enabled maintenance of monitoring results from multiple data sources,information mining of monitoring data,and visualization of results.The system's effectiveness was verified through application cases involving two operational monitoring projects,covering a total distance of 300 km and comprising 17061 monitoring points with 11 periods of monitoring data.The research results demonstrate that the system has effectively improved data storage efficiency through pre-entry of points and the combination and import of multiple coordinate systems.The availability of multiple statistical charts,such as the one map module and deformation curve,enriches the display of results and can serve as an effective tool for railway management and maintenance departments in handling high-speed railway monitoring data.
