SEDS在星载综合电子系统中的应用设计

Application of SEDS in Spacecraft

摘要:

针对目前如何实现星载软件快速集成和测试的需求，对空间数据系统咨询委员会CCSDS标准SIOS领域中SEDS的概念、应用背景以及国外最先展开应用的现状进行了分析；对星载综合电子系统的分层体系结构以及各层的功能、业务、构件、协议等进行了研究说明；基于该体系结构，给出了SEDS在星载综合电子系统研制过程中的顶层应用设计、以卫星遥测功能为例给出了SEDS的设计实例以及SEDS后续的扩展应用方法；在软件开发阶段、调试测试阶段、单元测试、组装测试以及确认测试阶段以SEDS为输入进行了设计验证，验证结果表明通过部分代码自动生成以及各阶段数据复用，SEDS的应用有助于实现星载接口的标准化并促进星载综合电子系统乃至整个航天器研制周期的缩短。

Abstract:

In order to realize the rapid integration and testing of spacecraf, the concept and the application background and foreign early application status of SEDS，which is in SIOS of Consultative Committee for Space Data Systems（CCSDS）are analyzed. The layered architecture and the functions, service, components and protocols of the integrated electronic system are studied. Based on this architecture, the top-level application design, design example of telemetry acquisition and application extension of SEDS in the development of the Service and Protocol System are presented. This design was verified in software development, debugging, unit testing, integrated testing, confirmation testing and the results show that the application of SEDS will give a support to standardize the satellite onboard interface and shorten the cycle of the Service and Protocol System and even the entire spacecraft by Auto-generated code and data reuse in different stages.
