Abstract

The invention discloses an airborne redundant network data transmission method, which solves the contradiction between strong real-time burst data transmission and ordinary service data transmission in an airborne unified network. The present invention is achieved through the following technical solutions: configuring a redundant network transmission mode according to an avionics system, configuring the redundant network as a split transmission, data backup transmission or network backup transmission mode, in the split transmission mode, the processor and Its application unit distributes data packets of different characteristic types to different redundant transmission networks through the processor interface for transmission; when configured as data backup transmission mode, the same data packets are transmitted through the redundant transmission network, and the transmission management of the sending node The unit copies the data into multiple copies and transmits it through multiple redundant networks; in the network backup mode, only part of the redundant transmission network is in the transmission state, and when the working network fails, the backup network is enabled through network backup.

Description

technical field

[0001] The invention relates to an airborne redundant network data transmission method, in particular to a method that supports heterogeneous transmission modes and can take into account the transmission of strong real-time burst data and common service data. Background technique

[0002] The avionics system has experienced the development process of separation, combination and integration, and is developing in the direction of high integration. The bus network is a key factor determining the performance of the airborne electronic system. The carrier electronic system puts forward higher requirements on the transmission rate, real-time performance and reliability of the bus network. The use of a unified airborne high-speed network can not only meet the requirements of high-speed interconnection and transmission, but also simplify system design, facilitate system integration, maintenance and management, and further improve the degree of integration of the avio...
