【摘要】：近年來,隨著航天技術(shù)的發(fā)展,航天器處理的數(shù)據(jù)向著多樣性、復(fù)雜性及標(biāo)準(zhǔn)國際化的趨勢。為了適應(yīng)空間數(shù)據(jù)通信技術(shù)發(fā)展的趨勢,為航天配電器通信系統(tǒng)選用合適的通信標(biāo)準(zhǔn)成為了重中之重。CCSDS(Consultative Committee for Space Data Systems)協(xié)議能夠突破傳統(tǒng)PCM體制固定采樣率和固定編碼格式的局限性,滿足星上復(fù)雜多變的數(shù)據(jù)源傳輸要求,成為了配電器通信標(biāo)準(zhǔn)的首選。本論文首先介紹了CCSDS協(xié)議的發(fā)展歷史,并與傳統(tǒng)的PCM體制作比較,論證了CCSDS協(xié)議應(yīng)用于配電器通信系統(tǒng)的優(yōu)越性和必要性;參照CCSDS一系列協(xié)議并結(jié)合本課題的實際需要,為配電器通信系統(tǒng)設(shè)計整體框架、各類功能所需要的包;并且設(shè)計了五種服務(wù)接口滿足包通信的需要,使得軟件模塊化;最后調(diào)用五種服務(wù)完成遙測參數(shù)處理及下傳、總線指令接收和解析、上電復(fù)位三個主要功能的設(shè)計,使得滿足配電器通信系統(tǒng)的要求。采用CCSDS協(xié)議設(shè)計的航天配電器通信系統(tǒng)能夠成為滿足未來空間數(shù)據(jù)通信技術(shù)需求的合理有效途徑。本論文的研究不僅能夠為航天配電器通信系統(tǒng)設(shè)計提供模板和參考,也為未來在航天配電器數(shù)據(jù)通信和CCSDS協(xié)議的應(yīng)用與國際合作打下堅實的技術(shù)基礎(chǔ)。
[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.
