Design And Research Of The Electromagnetic Spectrum Monitoring System And Relative Algorithm

With the rapid development of radio communication,more and more digitalized and intelligent radio stations have made the spectrum resources more and more intense,and the order of radio waves has become more and more complicated and unknown.In order to manage the spectrum scientifically and effectively,electromagnetic spectrum monitoring is essential and very important.Faced with the increasing demand of spectrum monitoring and monitoring network coverage,the spectrum data in spectrum monitoring work is getting larger and larger.In order to reduce the pressure of data storage and transmission,it is imperative to compress the monitoring data.In addition,the effective display of large amount of information is also an issue to be improved in the electromagnetic spectrum monitoring system.This paper analyzes the situation of spectrum monitoring and the trend of gridding monitoring.Combined with the requirements of spectrum monitoring,the architecture of electromagnetic spectrum monitoring system is designed and a software and hardware system of electromagnetic spectrum monitoring system is developed.In order to facilitate the interconnection of monitoring data and the unified access of multiple sensors,we realized the RMTP and the sensor access protocol.To optimize the operating experience of data for users,we use data visualization tools such as ECharts and Baidu map API in the client of the spectrum monitoring system to assist data display.In this paper,aiming at the mass data storage compression in the process of spectrum monitoring,a compressed storage scheme based on text compression and database table structure optimization is given.From the perspective of text compression,we study the lossless compression algorithms such as DEFLATE and LZMA and evaluate the compression performance of several lossless compression algorithms.In addition,it also proposes to store the spectrum monitoring data in the form of graphs and adopt JPEG compression.Then from the point of view of the structure of the database table,a hierarchical storage scheme for the statistical data and a scheme of database segmentation are designed.Finally,the compression module is applied to the electromagnetic spectrum monitoring software and it is able to achieve a good compression effect.It decreases the transmission time and the response time of electromagnetic spectrum monitoring system.
