Abstract

The invention discloses a DF file verification method based on the ARINC661. The DF file verification method based on the ARINC661 is characterized by comprising the following steps that firstly, a DF file is led in, information of the DF file is read and stored in a unified global variable, after the DF file is led in successively, data are analyzed and displayed according to a logical hierarchical structure, and attribute values and types of all parts are displayed in rows; secondly, a CDS server is started; thirdly, dynamic verification is performed on the DF file; fourthly, a test scrip of the Python format is automatically generated according to attributes of the corresponding parts of a DF and based on the ARINC661 protocol specifications, an execution environment and management are provided, original manual operation is converted into a script file to be stored, and therefore the verification process can be repeated. According to the DF file verification method based on the ARINC661, time in analyzing question reasons can be reduced, more emphasis of project testing can be put on logical functions, and therefore the development progress and the development efficiency of a whole project are ensured.

Description

technical field

[0001] The invention relates to a DF file verification method, in particular to an ARINC661-based DF file verification method. Background technique

[0002] With the increasing degree of integration of avionics and the continuous improvement of human-computer interaction requirements, as well as the different interfaces of electronic devices provided by aviation manufacturers, ARINC has developed a comprehensive solution for the aircraft cockpit display system CDS (Cockpit Display System, aircraft cockpit display system) to the user system. The UA (User Application, user system) interface defines the specification ARINC661, which has been used by airlines such as Airbus (A380, A400), Boeing (787), and has gradually become an industry standard after continuous revision.

[0003] ARINC661 aims to standardize the definition of cockpit display system CDS and the communication between CDS and user system UA. In a specific implementation manner, a definition file ...
