摘要
针对主要有源单机的备份设计广泛应用于通信卫星有效载荷设计中,备份环路中选择哪些单机作为工作单机通过开关矩阵来实现。以往的备份环路开关矩阵设计主要依靠经验对现有的备份环进行改造设计。随着载荷规模的提升,备份环的规模也不断增大,现有的设计方法很难保证设计的完备性。针对完备的备份环设计,通过对图论中关于图形的基本要素以及连通度的研究对开关备份环进行了图形和数学模型抽象。进一步结合Harary环的概念和图形的演变,提出一种新型的开关备份环的设计方法。并证明了这种设计方法的完备性。
The redundancy design for the main active units is widely used in the design of communication satellite payloads.The switching of the primary and redundant units is realized by the RF switch matrix.Currently,the design of the redundancy network mainly relies on rebuilding existing matrix based on experience.As the scale of the payload increases,the scale of the redundancy network also continues to increase.It is difficult for the existing design methods to meet the requirements of supporting all combinations of failure in the matrix.In this paper,the mathematical model of the redundancy network is abstracted,and a new method of designing the switch matrix is proposed through the Harary graph theorem in conjunction with the method of graphic construction.
