The Border Region Of Yunnan Electromagnetic Environment Monitoring And Evaluation System Research

With China’s southwest neighbours with the rapid development of economy and the prosperity of the border trade, border radio frequency increasingly serious conflict, must take effective measures to border frequency coordination, yunnan border frequency research and countermeasures study will be conducting border frequency coordination in yunnan province, provides the basis.In this paper, the electromagnetic environment of border, monitoring and evaluation method, forms the border inspection, evaluation standard electromagnetic environment, and on the basis of the electromagnetic environment evaluation database development border and assessment software, the monitoring results are storage, analysis and display, and combined with the fixed station border long-term periodic monitoring and evaluation data, make full use of monitoring analysis database, and integrate the frequency stations in our province database resource, and finally form the electromagnetic environment of long-term monitoring and evaluation border mechanism and applications system.The paper mainly work as follows:1、The electromagnetic environment monitoring the border region, determines the frequency band, monitoring content, monitoring monitoring parameters Settings, monitoring methods and results, and other technical requirements, and put forward the test site selection, including test environment requirements, power supply requirements, time determined, general signal testing method, GSM signal testing method, FM radio signal testing methods of the electromagnetic environment test method.2、Completed the border region electromagnetic environment assessment, proposed by background noise, take degree, frequency band time power than, than the large signal, choose some environment comprehensive evaluation, regional electromagnetic environment comprehensive evaluation of the electromagnetic environment of evaluation model, and gives the electromagnetic environment rating model.3、The monitoring and evaluation system development research, using UML use case diagram express electromagnetic environment assessment, spectrum diagram analysis, signal management, monitoring basic data management, testing data management function demand, on the system overall design and function modules of the input, output and processing design, gives the main database table structure.
