The redundancy networks are widely used in the design of communication satellite payloads. Currently, the design of the redundancy switch matrix mainly relies on rebuilding existing matrix based on experience. As the scale of the redundancy network continues to increase, it is difficult for the existing design methods to meet the requirements and ensure the optimal design, which requires both minimum number of switches and compliance of the redundant switching functions. In this paper, the mathematical model of the redundancy network is abstracted based on the graph theory, and the key elements in the model including vertices, edges and connectivity are introduced. A new method of designing the switch matrix is proposed through the Harary graph theorem in conjunction with the method of graphic construction. |
