摘要: 在首先介绍了空间站DMS网络结构的基础上,通过对DMS网络使用的FDDI、MIL-STD-1533B及IEEE802.4网络在各种情况下的可靠性分析,应用概率分析的方法得出了系统可靠性的数学模型,通过图示得出DMS网络可靠性随站点数及链路失效概率的变化情况,为空间站DMS网络可靠性设计提供了依据。

Abstract: This paper first introduces the structure of space station DMS.By analysing of the fault tolerance ability and the reliability of the FDDI、IEEE802 4、MIL-STD-1553B in each case,may be obtained the reliability mathematics models with probability analysis.It also illustrates the DMS reliability variation with the variation of station's quantity and link failure probability,and this provides the foundation of the reliability design of the space station DMS.
