Problems solved by technology

[0019] In the 1990s, the AirBus A380 project abandoned the ARINC 429 and ARINC 629 data buses based on factors such as cost, bus performance, flexibility, and applicability, and chose aviation full-duplex switched Ethernet, but now there is no aviation full-duplex Avionics Management System Based on Switched Ethernet

Abstract

The invention discloses an aviation electronic management system based on avionics full-duplex switched Ethernet (AFDX). The system comprises: a data generator, a sending end aviation electronic system, an AFDX switch and the like. The sending terminal aviation electronic system and a receiving end aviation electronic system are parallelly arranged between the data generator and the AFDX switch. The data generator generates a data source. After collecting various kinds of data frames which is from the data source of the data generator, a first aviation electronic subsystem sends the data frames to a first terminal system. The first terminal system sends the data frames to the AFDX switch. The AFDX switch distributes the data frames to the receiving end aviation electronic system. A second terminal system sends the received data frames to a second aviation electronic subsystem so as to carry out application layer processing. According to the invention, the terminal system and switch working parameter setting of the aviation electronic system based on the AFDX can be rapidly and accurately completed so as to rapidly and effectively realize AFDX network communication framework.

Description

technical field [0001] The invention relates to an avionics management system, in particular to an avionics management system based on aviation full-duplex switched Ethernet. Background technique [0002] With the continuous development of avionics technology, all avionics systems are in the stage of full completion of functions and rapid performance improvement, and the performance of airborne data bus communication bandwidth, network scale, communication scheduling and other aspects are getting higher and higher. demand. Although the ARINC 429 and MIL-STD-1553B data buses used in traditional combined avionics systems in the past have good reliability and maturity, but because of their low data transfer rate (MIL-STD-1553B bandwidth is 1Mbps, and Even the maximum transmission rate of ARINC 429 is only 100kbps), the expansion capability is limited (MIL-STD-1553B can only have 31 remote terminals at most, and each ARINC 429 bus can only have one data source, when the number ...
