一种基于大数据的轨道交通事件分析系统和方法
摘要：
本发明公开了一种基于大数据的轨道交通事件分析系统和方法。本发明对于系统事件数据，首先进行数据清洗，按照数据的有效属性进行清理、转换和规整，接着进行统计分类，再根据统计分类结果进行数据提取和筛除，然后按照预设时间窗的长度进行数据分段，最后对各分段做数据关联性分析。本发明不仅实现了数据整理和数据统计，而且挖掘了各个看似独立的事件间可能存在的内在关联关系，避免潜在危害，对提高轨道交通的运营管理水平提供了技术支持。
摘要（英）：

The invention discloses a rail transit event analysis system and method based on big data. According to the method, for system event data, data cleaning is firstly carried out, cleaning, conversion and normalization are carried out according to effective attributes of the data, then statistical classification is carried out, data extraction and screening are carried out according to statistical classification results, then data segmentation is carried out according to the length of a preset time window, and finally data correlation analysis is carried out on each segment. According to the method, data arrangement and data statistics are realized, possible internal association relationships among various events which seem to be independent are mined, potential hazards are avoided, and technical support is provided for improving the operation management level of rail transit.
