【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。
[Abstract]:With the development of satellite and remote sensing technology, the increasing amount of remote sensing data on satellite and the manufacturing cost of satellite have become new challenges. In order to meet these challenges, this paper introduces a high-speed data transmission bus into the remote sensing satellite data processing and transmission system with multiple remote sensors, which can not only meet the requirements of high data transmission rate. At the same time, it can also realize the standardization and intelligence of the interface of on-board equipment. Firstly, this paper introduces several kinds of satellite-borne buses, including SFODB bus, IEEE1394 bus, PCI bus and SpaceWire bus. After analyzing and comparing several kinds of buses, SpaceWire bus is selected as the standard bus interface. The SpaceWire network technology is introduced in detail. Then the related organizations (CCSDS organization) and protocol (AOS protocol) of on-board data processor are briefly introduced, and the problems faced by conventional data processor are discussed. By introducing standardized interface, routing function and status monitoring function, The construction of intelligent data processor can solve the problems faced by conventional data processor. This paper focuses on a kind of on-board intelligent data processor based on SpaceWire, introduces the function and overall design scheme of on-board intelligent data processor based on SpaceWire in detail, and introduces the configuration and structure of on-board intelligent data processor based on SpaceWire. The internal functional modules are designed in detail and verified on the hardware platform, which shows that the on-board intelligent data processor based on SpaceWire meets the functional requirements.
