Method for determining switch network

Abstract

A method for determining a switch network comprises the steps: (1) splitting the switch network into (M-N) small rings according to the number N of master single machines and the number (M-N) of backup single machines, wherein, the switch network is connected with the master ringlet machines and the backup single machines; M is greater than N; (M-N) is less than or identical to 4; and each small ring only comprises a backup single machine; (2) for each small ring, using a master switch with four ports and a relay switch to connect the master single machines with the backup single machines forforming a small ring structure, wherein the switch connection modes are performed respectively according to odd number or even number of the master single machines contained in the small ring; and (3) constituting various small rings into a big ring, so as to obtain a final switch network. By the method, under a condition that the numbers of the master and backup single machines are determined, adesign scheme of the switch network can be determined fast by three steps of splitting a big network into small networks, determining the connecting relation of the small networks and constituting the small networks into a big network; and the determined switch network satisfies the completeness, minimality, first backup compatibility and first backup shortest performance of a redundant network.

Description

technical field [0001] The invention belongs to the field of reliability design of satellites and other projects, and relates to a switch network for switching between main and backup single machines. Background technique [0002] Modern communication satellites are long-lived and highly reliable satellites. In order to ensure that the transponders can work normally for a long time, in addition to using a high-reliability and long-lived stand-alone, it is particularly important to carry out redundant design for key components. The key active units in the transparent transponder, including receivers, traveling wave tube amplifiers and beacons, all adopt redundant design. Redundancy design is to add several additional backup stand-alone machines in addition to the main stand-alone machine in normal use, and at the same time design a switch network at the input and output ends of the master-standby stand-alone unit, and control the switching of the master-standby stand-alone ma...

AI Technical Summary

Problems solved by technology

Such a design method not only takes a long time to design, but also cannot guarantee the rationality of the design

Especially when the scale of the redundant ring is relatively large, how to design and verify whether the redundant ring is effective and optimal is also a relatively complicated problem
