摘　　要：针对未来载人航天器种类、规模及功能多样化的特点,尤其是多航天器构建的复杂大型载人航天器,对现有载人航天器空间数据系统的通用性、可扩展性、兼容性进行分析,提出了1种基于多层1553B总线的多构型、高可靠、可重构、大负载的空间数据系统器载网络架构和1种基于CCSDS的载人航天器空间数据系统协议体系架构。器载网络和协议体系架构可支持载人航天器天地间、器间及器载业务和协议的标准化设计,促进设备及软件的模块化和通用化,增强载人航天器的兼容性及可扩展性,便于支持未来可能的国际合作。Considering the characteristics in category,scale and function diversification of the future manned spacecraft,especially the complex large manned space facility composed of multiple spacecraft,the generality,scalability and compatibility of the existing manned spacecraft space data system were analyzed.A multi-configuration,highly reliable,reconfigurable and large-load on-board network architecture for the space data system based on multi-layer 1553B bus was proposed,and a protocol architecture for the space link subnetwork and on-board network protocol system based on CCSDS protocol standards was put forward.The architecture of the on-board network and protocol may provide support for the standardized design of spacecraft,promote the modularization and generalization of equipment and software,enhance the compatibility and scalability of manned spacecraft,and facilitate potential future international cooperation.
