[Abstract]:Satellite communication, as a common communication mode, can play an important role in many situations, while portable RF front-end devices are widely used because of their small size and high flexibility under networking. In this paper, the monitoring subsystem of portable RF front-end equipment is taken as the research object. In recent years, with the development of computer application technology and remote control technology, especially the progress of wireless local area network (WLAN) technology, a new model based on C / S model is designed based on portable RF equipment. Monitoring system in wireless network environment becomes very necessary. The main purpose of the monitoring system is to guide the user to complete the star-finding task through a simple and intuitive user interface. Through the connection with antenna system and satellite modem, the effect of star finding is displayed in the user interface, so that the precision of radio frequency equipment can basically meet the requirements, and the communication link between radio frequency equipment and lower computer can be monitored. This paper first introduces the development of portable radio frequency equipment at home and abroad, the composition of portable radio frequency equipment and its working principle and some common technologies, and then gives a detailed introduction to the overall design ideas and design scheme of the monitoring system. It includes the hardware part and the software part. The function case diagram of each sub-module is given by modeling method and the design of software protocol and database is emphasized. Followed by the introduction of the java language and some core programming techniques used in the development of the system, the protocol parsing algorithm is realized by coding. Finally, the debugging process of the system is illustrated with an example, and the common errors are analyzed and solved. The system functional test results are given. The research results have been tested in many ways, and meet the performance requirements stipulated in the contract, and have been authenticated and accepted.
