Embodiment Construction

[0035] The basis of the airborne AFDX network data monitoring method proposed by the present invention is that as a part of the aircraft airborne central maintenance system, it resides in the airborne integrated core processing computer, and is connected with the capture port of the AFDX switch through a dedicated data capture channel, thereby Real-time monitoring of various data interacted in the aircraft bus network.

[0036] combine figure 1 It can be seen that the integrated core processing computer mainly consists of the following modules: AFDX switch module (as the central node in the AFDX network, connecting each terminal system in the network), power supply module (power supply for each module in the integrated core processing computer), general The processing module (runs various application programs and completes the integrated core processing function of the avionics system), the graphic image module (runs the application programs related to graphic images), and the...

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...
