摘　　要：为提升航天器部件的即插即用和自主能力,针对电子数据单技术在航天领域应用的问题,文章从空间数据系统咨询委员会(CCSDS)的空间数据系统参考架构(RASDS)信息视角,论述了信息对象的描述方法和抽象数据架构、数据模型、具体数据对象的3个建模过程。采用该方法,结合CCSDS的可扩展标记语言的遥测遥控信息交换标准(XTCE)和航天器接口业务电子数据单(SEDS)标准,分析了针对航天器所需要的遥测、遥控和部件接入等信息对象的应用场景,提出了相应的插件式电子数据单工具系统的设计思路,给出了在航天领域电子数据单技术研究方向的建议。In order to realize plug-and-play ability and prompt autonomous capabilities of component onboard, how to use electronic data sheet(EDS) technology on spacecraft is a problem. Therefore information object description methods and modeling processes are described in this essay, from the information viewpoint of CCSDS reference architecture of space data system(RASDS),mainly including three modeling processes: abstract data architecture, data model and actual data object. Adopting these methods, reference to CCSDS XTCE and SEDS standards, the information objects of telemetry, telecommand and plug-in components which spacecraft needed, and their application scenarios are analyzed. Correspondingly design idea of EDS tools system using plug-in method is put forward. Some research directions of EDS in aerospace area are proposed.
