摘要
针对当前卫星上存在电缆多、电气连接复杂等问题,文章提出用ZigBee无线网络代替传统星载总线的设计构想。结合空间应用的特点,对ZigBee星载应用的优势进行了分析,并提出了相应的可行性设计建议,包括ZigBee星载应用的系统组成、网络拓扑、帧结构以及网络节点的实现方案,研究结果可以为未来卫星和空间站电子系统的设计提供参考。
Considering such issues as abundant cables and complex electrical connections onboard satellite, this paper puts forward an idea of the design of ZigBee wireless network instead of the traditional satellite bus. In combination with the characteristics of satellite applications, the paper analyses advantages of ZigBee wireless network for satellite application, introduces some feasible suggestions on ZigBee system components, network topology, frame structure and implementa- tion schemes for satellite applications of wireless networks, which can be a reference for future design of satellite and space station avionics.
