Dual-redundancy ring network architecture

Abstract

The invention provides a dual-redundancy ring network architecture, and the architecture is characterized in that the architecture comprises a first ring network and a second ring network; the first ring network comprises a first core processor (11), a first remote interface unit (31), a second remote interface unit (32), a first remote power distribution unit (41), a second remote power distribution unit (42), a first independent controller (51) and a second independent controller (52); the second ring network comprises a second core processor (12), a third remote interface unit (32), a fourth remote interface unit (34), a third remote power distribution unit (43), a fourth remote power distribution unit (44), a third independent controller (53) and a fourth independent controller (54), wherein the second core processor (12) is connected with the first core processor (11) through a network branch line (6).

Description

technical field [0001] The invention relates to the architecture design of an aviation airborne system, in particular to a double-redundancy ring network architecture. Background technique [0002] Ring networks such as 1394B have been used as airborne buses in foreign advanced aircraft such as F35. This type of ring network is generally designed with three degrees of redundancy, the configuration is relatively complex, and the design and manufacturing costs are relatively high. It is generally suitable for the bus of high-real-time and fast-response flight control systems or aircraft management systems. At home and abroad, there is no example of designing the 1394B ring network into a dual-redundancy architecture as the main bus of the electromechanical system. Contents of the invention [0003] In order to solve the above technical problems, this application provides a dual-redundancy ring network architecture, which saves costs and improves the security of the network ...
