Abstract

The invention discloses an AFDX network data analysis system and method applied to a civil aircraft, which relates to the civil aircraft field. The system comprises a data processing unit, a data dictionary, a data state configuration unit and a data storage unit. The data dictionary reads the data structure and attributes of the AFDX device, and generates a data structure document. The data stateconfiguration unit identifies the data structure document and generates a data configuration interface. The data storage unit stores the parsed data of the data processing unit. The data processing unit collects the original data from the exchanger, obtains the data structure document to guide the data analysis, obtains the effective range, compares with the analysis data, controls the reading and writing of the data storage unit, saves the analysis data and the over-limit data to the data storage unit, and reads out the data in the data storage unit for the second analysis. It solves the problem of data parsing that can not support multiple avionics equipments, and realizes the unified management of multiple avionics equipments.

Description

technical field [0001] The invention relates to the field of civil aircraft, in particular to an AFDX network data analysis system and method applied to civil aircraft. Background technique [0002] With the increasing complexity and integration of avionics on civil aircraft, the data transmission rate and data volume between devices are constantly increasing, and the traditional avionics bus (such as: ARINC429 bus) can no longer meet the requirements. The AFDX network (ARINC664 bus) has the characteristics of easy maintenance and light weight on the physical line, so it is widely used in the manufacture of civil aircraft and avionics equipment in the world. [0003] At present, the analysis system of AFDX network data is mostly used for specific avionics equipment, and cannot support the data analysis of the entire avionics system or multiple avionics equipment, and the current AFDX data analysis system does not analyze network data deeply enough, and users cannot intuitive...
