Abstract

The invention belongs to the technical field of computer software design, and specifically relates to a large aircraft integrated and modularized avionics system airborne Avionics Full Duplex Switched Ethernet (AFDX) network data monitoring method. The method comprises the following steps of (1) determining a data content needing to be monitored by a user according to a flight mission; (2) configuring a status monitoring table according to the data content needing to be monitored; (3) receiving monitoring data needing to be monitored, and processing the data by using a two-level screening and three-level cache mechanism; (4) downloading a stored file from a large capacity module by the user, and monitoring a bus network of an aircraft according to the data in the file. By the method disclosed by the invention, various different monitoring requirements in an AFDX network are met; massive data frames in the AFDX network are accurately obtained, and are supplied to the user for analysis so as to realize the monitoring.

Description

technical field

[0001] The invention belongs to the technical field of computer software design, and in particular relates to a data monitoring method of an airborne AFDX network of a comprehensive modular avionics system of a large aircraft. Background technique

[0002] Avionics Full Duplex Switched Ethernet (AFDX) is a full-duplex, high data rate, dual-redundant network with higher reliability, bandwidth and lower latency. And it overcomes the shortcomings of complicated wiring, excessive weight, difficult maintenance and modification. As a new type of aviation network interconnection technology, AFDX has been successfully applied on Airbus A380 / 400M, Boeing B787 and other aircraft, and has become the basis for the current international mainstream avionics network interconnection.

[0003] The data monitoring function captures and stores various original parameters during the flight of the aircraft (capturing and storing various data in the aircraft bus network through t...
