轨道检测数据集成存储与数据质量评价

针对当前轨道检测体系产生的多源异构检测数据未能有效管理,导致数据质量参差不齐,无法有效支撑养护维修决策的问题,本文以动态检测数据为基础,提出了轨道检测数据融合管理业务集成架构,并基于集中存储、预处理、质量评价、按需发布等业务需求,设计了检测数据融合管理业务集成系统。系统采用分布式管理体系与数据共享模式,对检测数据的存储与共享进行规范化管理;运用数据预处理与数据质量评价方法,实现了检测数据自动化和标准化处理,从而为线路质量分析评价提供稳定、可靠的检测数据。

Integrated Storage for Track Inspection Data and Data Quality Evaluation

The multi-source heterogeneous inspection data generated from current track inspection system fail to be effectively managed,which lead to data quality uneven,unable to effectively assist maintenance decision. To solve these problems,this paper put forward an integrated management architecture for the track inspection data based on dynamic inspection data. According to designed business requirements such as quality evaluations,concentrated storage,pre-processing and on-demand releases,an integrated management system for the track inspection data was designed. The system utilizes distributed management system and data sharing mode to regulate and standardize the storage and sharing of inspection data. By using data pre-processing techniques and data quality evaluation methods,the automation and standardization of inspection data are realized,providing stable and reliable inspection data for line quality analysis and evaluation.
