便携式卫星地球站测试系统的设计与实现
[Abstract]:When confronted with sudden natural disasters, major accidents, wars and so on, communication equipment and power system are seriously damaged. Satellite communication can quickly resume communication in a short time, transmit a large amount of data, and is not limited by region. Portable satellite earth station is widely used in emergency communication because of its small caliber, light weight and easy to carry. Before the satellite earth station is put into operation, strict network testing is needed. With the development of WLAN technology, computer application technology and remote control technology, it is very important to design a multifunctional and high performance test system. The portable satellite earth station test system designed in this paper can collect and process the data accurately. It has the functions of quickly correcting the angle, obtaining accurate antenna parameters, and storing large amount of memory. The remote monitoring and testing is realized. Taking the portable satellite earth station as the research object, the design process and implementation method of the test system are introduced in detail in this paper. Firstly, the working principle and system composition of the satellite earth station are briefly introduced, and the design principle of the satellite earth station is expounded. Then, the test scheme based on LAN, some basic parameters of antenna test and its calculation formula are described. Then the software design process of the test system is given, and the detailed design of each function module and the key technologies used in the system development are introduced, such as Socket communication programming technology, database design and graphical user interface design. Finally, the software interface results of the test system are given, and the antenna pattern obtained by the test is analyzed. The automatic test of system software is generated automatically by Robot Framework, test report, and the analysis test result is displayed in the report. After many tests, the portable satellite earth station test system designed in this paper meets the design requirements, realizes the antenna automatic test, and automatically generates the test report.
