一种应用SpaceWire总线的即插即用星载计算机体系结构设计
A Plug-and-play Computer Architecture Design Based on SpaceWire Bus
摘要
Abstract
To address the limitations of long system integration cycle and difficult expansion caused by the heterogeneity of interfaces and software are protocols in traditional on-board com-puter(OBC),the technical system represented by the Space Plug and Play Electronic System Ar-chitecture(SPA)in the United States is studied,and a on-board computer architecture design scheme based on the SpaceWire bus is proposed in this paper.Firstly,the fundamental principles and implementation methodologies of plug-and-play technology are elaborated to ensure that the designed system is compatible with the SPA standard.Secondly,with the satellite attitude and control system(AOCS)as the application background,a proof-of-concept prototype is devel-oped,encompassing both hardware implementation and software architecture.To resolve univer-sality issues,an additional sensor interface module is designed.Furthermore,the synchronization network mechanism of the electronic system is improved using a SpaceWire time-code based de-sign.Finally,ground experiments demonstrate that the proposed architecture effectively sup-ports the rapid integration of on-board computers and enables stable closed-loop operation of the satellite AOCS.关键词
