卫星通信地球站智能切换单元的设计与实现

卫星通信系统中,可靠性是衡量地球站正常运行的重要指标之一,射频设备的稳定是地球站可靠运行的关键。针对有多套卫通系统的地球站,提出了关键设备资源调度思想,设计了一种简捷、高效、可靠的智能切换单元,实现了地球站之间射频设备的互相备份。重点对硬件设计中的关键部件和软件构架进行了设计和分析。在不增加设备的前提下,方便地球站之间关键设备的替代使用,通过实践应用,验证了智能切换单元的优异性能。

Design and Realization of Intelligent Switching Unit for Satellite Communication Earth Station

The reliability of satellite communication system is one of the most important indicators of the earth station＇ s normaloperation,and the stability of RF devices is the key to ensure the reliable operation of earth station. Aiming at an earth station withmuhiple sets of satellite communication system,the idea of key devices resource scheduling is provided.A simple,efficient and reliableintelligent switching unit is designed, and the mutual backup of RF devices is realized among earth stations. This paper focuses ondesigning and analyzing the key hardware components and the software architecture. Without adding more devices, the intelligentswitching unit is convenient for the replacement of key devices among earth stations. The actual application verifies the excellentcapability of this intelligent switching unit.
