Embodiment 1

[0025] like figure 1 As shown, an EAFR data download processing method of the research model C919, the method is as follows:

[0026] A. The data acquisition component transmits the collected AFDX frame structure data to the EAFR recorder through the ARINC 664 data bus based on the AFDX aviation data network. In this embodiment, the EAFR recorder (Enhanced Airborne FlightRecorder, referred to as EAFR) is selected from the United States General Electric Company ( The enhanced aerial flight recorder produced by General Electric Company, referred to as GE), the present invention has a built-in recorder electronic record file (FlightRecorder Electronic Documentation, referred to as FRED) in the EAFR recorder. In this embodiment, the recorder electronic record file is in accordance with ARINC The 647A specification requires that it be written in the .XML file format. The electronic record file of the recorder is also called the FRED file. The electronic record file of the recorder ...

Embodiment 2

[0033] like Figure 2 to Figure 4 As shown, an EAFR data download processing method of the research model C919, the method is as follows:

[0034] A. The data acquisition component transmits the collected AFDX frame structure data to the EAFR recorder through the ARINC 664 data bus based on the AFDX aviation data network. The EAFR recorder has a built-in recorder electronic record file (FlightRecorder Electronic Documentation, referred to as FRED), In this embodiment, the electronic record file of the recorder is written in the .XML file format according to the requirements of ARINC 647A, and the electronic record file of the recorder is also called FRED file. File format storage, recorder electronic record file is a descriptive file that stores rules and sequences. The FRED file is written in accordance with the requirements of the ARINC 647A specification, which mainly includes the following three parts:

[0035] a) Header file: The first section of the FRED file has a fix...

Abstract

The invention discloses an EAFR data downloading processing method and system of a research model C919, the system comprises a data acquisition assembly, an EAFR recorder, an EAFR data downloading device, an AirFASE software platform and CEFA simulation software, the data acquisition assembly performs AFDX frame structure data acquisition through an ARINC664 data bus based on an AFDX aeronautical data network, the EAFR recorder is internally provided with a recorder electronization recording file, and the EAFR data downloading device is provided with a C919 EAFR data downloading module. The EAFR recorder stores the AFDX frame structure data collected by the data collection assembly as EAFR frame structure data according to a recorder electronic record file; and the AirFASE software platform decodes the EAFR data, and the CEFA simulation software performs flight data simulation production. The EAFR recorder is used as a server, the EAFR data downloading device is used as a client to construct the data communication Ethernet so as to facilitate EAFR data downloading, the EAFR data downloading problem of a research machine type C919 is solved, and a complete set of solution of data downloading and simulation manufacturing is provided.

Description

technical field [0001] The invention relates to the field of civil aviation flight data, in particular to a method and system for downloading and processing EAFR data of a C919 model under development. Background technique [0002] The civil aviation regulations of various countries in the world mandate that passenger or cargo aircraft and helicopters must be equipped with flight data recorders; flight data recorders are used as airborne data recording equipment to record the flight status of the aircraft, crew operations, system and equipment operations, Various data such as the external environment can be used to realize the investigation of the cause of flight accidents, data analysis of unsafe events and cases, and provide detailed data support for the improvement of aircraft design and maintenance or training programs. Traditional aircraft (A318 / 319 / 320321, B737 / 747 / 757 / 767 / 777, etc.) are based on ARINC 429 data bus for information transmission, C919, A380, A350, B787 a...
