【摘要】 随着卫星和遥感技术的发展,卫星上日益增长的遥感数据量和卫星的制造成本成为了新的挑战。本文正是为了应对这些挑战,在拥有多遥感器的遥感卫星数据处理与传输系统中引入高速数据传输总线,这样不仅能适应高数据传输速率的要求,同时还可以实现星上设备接口的标准化和智能化。论文首先介绍了目前常用的几种星载总线,包括SFODB总线、IEEE1394总线、PCI总线以及SpaceWire总线,经过对几种总线进行分析和比较,选择SpaceWire总线做为标准总线接口,并对SpaceWire网络技术进行详细介绍。然后对星载数据处理器的相关组织(CCSDS组织)和协议(AOS协议)进行了简要的介绍,讨论了常规数据处理器面临的问题,通过引入标准化接口、路由功能、状态监控功能,构建智能化的数据处理器,可解决常规数据处理器面临的问题。论文重点研究了一种基于SpaceWire的星载智能数据处理器,详细介绍了基于SpaceWire的星载智能数据处理器的功能和总体设计方案,并对基于SpaceWire的星载智能数据处理器外形结构、内部各个功能模块进行详细设计,并在硬件平台上得到验证,说明基于SpaceWire的星载智能数据处理器满足各项功能要求。更多还原

【Abstract】 With the development of satellite and remote sensing technology, there are two challenges should be coped with, more and more data generated by remote sensors and the cost of satellites manufacture. In order to cope with these challenges, the high-speed data bus is introduced to the data transfer system of satellites which have many remote sensors. It not only could satisfy the request of high-speed data transfer, but also could reduce the cost of manufacture.Several onboard data buses including SFODB bus, IEEE1394bus, PCI bus and Space Wire bus are introduced, analyzed, after and compared. The Space Wire bus is choosed as standard bus interface and the Space Wire network technology are introduced in details.Secondly, the onboard data processor related organization (Consultative Committee for Space Data Systems) and protocol (Advanced Orbiting System) are introduced in brief. Problems of the regular data processor are discussed, too. The problems could be solved by introducing standardized interfaces, routing functions, condition monitoring function, build intelligent data processor.An Intellectualized onboard Data Processor base on Space Wire was studied, mainly. At first, the function and overall design scheme of data processor were introduced. And the structure, each function module of data processor was introduced, too. Through verified on the hardware platform, various functions of the designd Data are able to fulfil the requirement.更多还原
