The Application And Research Of Radio Monitoring System In Electromagnetic Interference

Along with the rapid growth of social and science technology,the quantity of the communication equipment increas,electromagnetic environment grows sophisticated pyramidally,limited radio resources become more congesting,which has brought new challenges and difficulties of the distribution and management spectrum resources.The radio monitoring is the more important part than other of the management,and provides the basis for the decision-making of the spectrum management.Radio monitoring is a series of search and receive,analysis and identification,monitoring direction finding,parameters extraction and positioning of the signal in a specific region for the job.By signal processing technology,the type,location and related parameters of signal are acquired,so as to identify the validity of the signal and manage it.The development of radio monitoring in our country is very late,but the progress of the development is particularly rapid.Fixed monitoring station,all kinds of monitoring instruments and equipment,mobile monitoring station,etc.,are rapidly increasing,and improving the level of radio spectrum monitoring.At the same time,with the continuous improvement of communication technology,radio monitoring need to solve more and more problems,communication services,increasing the amount of communication,the use of more and more intensive,monitoring station construction distribution to be more scientific and reasonable,monitoring equipment manufacturers are not consistent,the construction of these issues for radio monitoring network is a particularly great challenge.When the existing monitoring system to find the interference signal,first determine the frequency and the direction of the wave,and then use artificial approximation method to determine the interference signal.Future monitoring system requires intelligent monitoring function,through the unattended station computer system check-in,reduce human intervention,reduce the man-made errors,reduce staffs work intensity,improve the work efficiency.Therefore,the whole network monitoring,sharing monitoring data and analysis results are used to improve the efficiency of radio monitoring is an important direction of the development of radio monitoring technology.The future monitoring system will be intelligent integrated monitoring system,let the computer instead of people to perform a series of monitoring and analysis.Intelligent analysis and statistics of the monitoring data,and then upload to the monitoring control center,other sub monitoring system to automatically share the monitoring data and analysis results,such as the basic characteristics of radio and television,public mobile communication signals,and some of the characteristics of the interference signal data.In addition,each control center,fixed monitoring station,vehicle monitoring stations,small station,between shifting monitoring stations and other different radio monitoring equipment or network can also be through wireless or SMS way monitoring network,each system cooperating intelligent monitoring.Radio monitoring for the management department to supply the technical support,to analyze and solve the problem from the skill level,more scientific and intelligent display invisible electromagnetic environment and the use of spectrum occupancy and to the radio management department provides effective reference data.The database of radio monitoring is the important reference data for the identification of radio management of unknown signals..It is the effective estimation of the electromagnetic and frequency usage,and it is a very important process in the development of radio technology.New radio monitoring system is proposed in this paper,after all,only a model of the system,including some of the function module description,the basic design and construction of the network is still confined to the stage theory,has not been substantial validation in practical application.So,to make the system applied in the actual work also have to experience a long waiting process,there are many need to run in the improvement.
