【摘要】：近年来,随着航天技术的发展,航天器处理的数据向着多样性、复杂性及标准国际化的趋势。为了适应空间数据通信技术发展的趋势,为航天配电器通信系统选用合适的通信标准成为了重中之重。CCSDS(Consultative Committee for Space Data Systems)协议能够突破传统PCM体制固定采样率和固定编码格式的局限性,满足星上复杂多变的数据源传输要求,成为了配电器通信标准的首选。本论文首先介绍了CCSDS协议的发展历史,并与传统的PCM体制作比较,论证了CCSDS协议应用于配电器通信系统的优越性和必要性;参照CCSDS一系列协议并结合本课题的实际需要,为配电器通信系统设计整体框架、各类功能所需要的包;并且设计了五种服务接口满足包通信的需要,使得软件模块化;最后调用五种服务完成遥测参数处理及下传、总线指令接收和解析、上电复位三个主要功能的设计,使得满足配电器通信系统的要求。采用CCSDS协议设计的航天配电器通信系统能够成为满足未来空间数据通信技术需求的合理有效途径。本论文的研究不仅能够为航天配电器通信系统设计提供模板和参考,也为未来在航天配电器数据通信和CCSDS协议的应用与国际合作打下坚实的技术基础。
[Abstract]:In recent years, with the development of space technology, the data processed by spacecraft tend to be diversified, complex and internationalized.In order to adapt to the trend of spatial data communication technology,The choice of appropriate communication standard for spaceflight distribution equipment communication system has become the top priority. The CCSD Consultative Committee for Space Data Systems can break through the limitation of fixed sampling rate and fixed coding format of traditional PCM system, and meet the requirements of complex and changeable data source transmission on board.Has become the first choice of communication standards for distribution equipment.This paper first introduces the development history of CCSDS protocol, and compares it with the traditional PCM system, and demonstrates the superiority and necessity of applying CCSDS protocol to the communication system of distribution equipment, referring to a series of CCSDS protocols and combining with the actual needs of this subject.Design the whole frame for the distribution equipment communication system, and design five kinds of service interfaces to meet the need of packet communication, make the software modularization, finally call five kinds of services to complete the telemetry parameter processing and transmission,The design of three main functions of bus instruction receiving and analyzing and power-on reset makes it meet the requirements of distribution communication system.The spaceflight distribution equipment communication system designed by CCSDS protocol can be a reasonable and effective way to meet the needs of future spatial data communication technology.The research in this paper can not only provide the template and reference for the design of spaceflight distribution equipment communication system, but also lay a solid technical foundation for the future application and international cooperation of spaceflight distribution equipment data communication and CCSDS protocol.
