The Research Of Radio Monitoring Data Post-processing And Visualization Technology

In order to improve the accuracy and efficiency of the radio monitoring,it is an urgent need for the new generation of radio monitoring tasks to make use of the monitoring data to in-depth analysis and mining.Based on the background and project requirements,this paper deeply analyzes the characteristics of the monitoring data and puts forward some effective data processing methods which achieved considerable effect,besides,this paper use some technical means to visually show the monitoring results and provides a way for the future of radio monitoring.Firstly,this paper analyzes the two important types of data that are electromagnetic power distribution data and abnormal signal positioning data in the radio monitoring network from the point of the spatial data characteristics and the method of analysis.It is found that there exists a large amount of redundancy in the electromagnetic power distribution data and a small number of noise points in the abnormal signal positioning,which will lay the foundation for the following data processing.Secondly,in order to reduce the redundancy of the electromagnetic power distribution data,improve the efficiency of data collection,transmission and query,and save resources,this paper proposes a data compression method based on the feature.This method effectively extracts larger information and abandons redundancy data combined with the road net patterns and the surrounding electromagnetic environment,which can also restore the compressed data and there exists error in the controllable range between restored data and original data.In order to improve the reliability of the localization results,a hybrid clustering method based on density is adopted in this paper.This method combines the advantages of OPTICS and DBSCAN algorithm,and can give the position and the moving track of the signal more accurately.Finally,in order to express the results of radio monitoring,this paper studies the visualization technology based on GIS.A results display system was designed and implemented based on the Java platform and related components in this article.The system uses the Oracle database,Baidu maps,Swing components,WebBrowser controls,etc.,which to achieve the goal of terminal information query,station display,electromagnetic power analysis,positioning results display and other functions.
