摘要
Abstract
Currently,the master-slave indirect grid-connected data bus system is mostly used in multi-compartment combined spacecraft.In response to the shortcomings of this system,such as the lack of bus control right migration capability and system reconfiguration capability,large sys-tem delay and complex system composition,a peer-to-peer direct-connection and reconfigurable combined spacecraft data bus system is proposed in this paper.Under the condition of limited re-sources,it achieves the reliable direct-connection and rapid synchronization of the multi-craft data bus system,reduces the data transmission latency,and ensures the reliability and security of the combined spacecraft data bus system network.Through in-orbit validation,the research results can provide reference for the design of data communication system between multiple modules of subsequent combined spacecraft.关键词
