Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] A kind of airborne network with distributed switching of the present invention is the bottom physical connection network formed by M vertical buses parallel to each other and N horizontal buses parallel to each other in a three-dimensional space in a cross layout mode (in a machine The number of vertical and horizontal buses in the carrier network must be the same, that is, M=N), and the access of multiple airborne devices is distributed on the space intersection point. see figure 1 As shown, in the local area network composed of multiple vertical and horizontal buses, the intersection point of the vertical bus and the horizontal bus in the three-dimensional space is marked as a node; and the airborne equipment is connected to the node, and the node is used for the communication terminal Provide transceiver and two-hop relay services. In order to rea...

Abstract

The invention discloses an airborne network with distributed switching and an information communication method under the same. The airborne network is a communication network formed by accessing communication service nodes with transceiving and relaying functions based on a physical connection structure formed by intersecting mutually parallel transverse buses and mutually parallel longitudinal buses. Subsequently, the time division and routing strategies of the communication service nodes under the structure, and a damage handling mode when a few nodes are broken down are provided. The communication service mode is adopted to provide large throughput, high real-time and high survivability for the airborne network with the distributed switching.

Description

technical field [0001] The present invention relates to an airborne network applicable to the comprehensive technology of advanced avionics, more particularly, refers to an airborne network capable of realizing distributed switching. Background technique [0002] The effective operation of the avionics system in the limited space of the aircraft needs to solve two problems: the first is the sharing of information resources; the second is the sharing of equipment resources. Only when all devices, modules and components are connected into a network can they share information and resource devices, and the performance of the entire system can be fully utilized. The airborne network is a means to connect the equipment, modules and components in the aircraft platform. It is a core supporting technology to realize the integration of avionics, and it is also considered as the "central nerve" of the aircraft. [0003] The connected devices, modules and components on the aircraft are...
