A Test Approach And Realization For Radio Monitoring And Direction Finding System On Open Area Test Site

With the rapid development of social economy in China,as the radio management infrastructure gradually improved,several problems appeared in the process.Radio management departments purchased Radio monitoring and direction finding system which lack of third party certification to the objective test;Radio monitoring and direction finding system which in use are aging and the indicators are in worsening,lack of professional? targeted testing and maintenance;Radio monitoring database of the direction finding system will update regularly,as the environment,equipment,indicators of regular the changed.The system need a relatively good electromagnetic environment to do the basic data collection sites.In order to solve the problems of daily radio management work mentioned above,in the meantime,implement the instructions of Mr Liu Lihua,Deputy Minister of Industry and Information Technology,who puts forward on strengthening the "four systems" at the 2012 National Radio Management Symposium,Radio Monitoring Center organizes the compilation of the communications industry standard?The testing standard of VHF / UHF radio direction finding system?.Following this tendency,Ningxia radio management departments get support for built the first standard calibration field of VHF / UHF radio monitoring system in the country,in time to make the standard landing.In order to realize the automatic testing work,there must have a set of fully automated testing software,connect various nodes like measured system,signal source,contrast receiving system and so on through the network interface to achieve remote operation and complete the relevant testing and verification work.After studying ?The testing standard of VHF / UHF radio direction finding system? and the equipment programming manual of receiving and transmitting signal,by using the core idea of database technology and software engineering,follow the basic principle of development,completed the system's physical architecture and software architecture design,implements the calls and data collection from various equipment and measured system finally the program is written in the C language,through the real test to verify the operation of the system,formed a complete data and graphics data.The development of the system has a certain practical significance,It can improve the test efficiency and reduce the external interference factors,leading to improve the test level and capability of Ningxia standard calibration field of radio monitoring system.
