无线电监测数据仓库的构建与应用研究

对于无线电监测和相关海量数据的检测,单纯的存储和查询无法满足实际应用的需求。为满足无线电监测业务中的高层决策和智能监管业务需求,对业务系统中的数据进行预处理,设计并开发了无线电监测数据仓库。首先,为实现业务系统和信息化平台中源数据的采集,设计ETL规则；其次,设计维度、度量、级别,建立不明信号数据立方体；最后,实现多维数据模型的分析、预测和决策功能,从而增强不明信号相关业务功能。

Research on Construction and Application of Radio Monitoring Data Warehouse

When faced with massive data on radio signal detection and surveillance,the simple storage and queries fail to meet the application requirements.In order to satisfy the requirements of higher level decision making in radio monitoring system and intelligent monitoring services,a radio monitoring data warehouse was designed based on the preprocessing of the data collected from existing radio monitoring system.First,ETL (Extract/Transform/Load) rules were defined to collect data from application systems and information platforms.Second,an unknown signal data cube was built after the design of dimensions,measures,and levels.Finally,the implementation of analysis,prediction and decision-making functions based on multidimensional data models was done.It helps to enhance the business functions relatedwith unknown signals.
