Problems solved by technology

[0002] With the application of ARINC661 standard to military aircraft and the improvement of the comprehensiveness of military aircraft avionics system, the aircraft cockpit display system based on ARINC661 standard becomes more and more complex
However, the traditional aircraft cockpit display system detection is only realized by system joint test. Because the system joint test is difficult to carry out boundary test and abnormal test, the test process is not sufficient. As a result, it is difficult to fully test the aircraft cockpit display system only by system joint test. Effectively guarantee the quality of equipment
[0003] In addition, the existing tests are basically aimed at the verification of the definition file (DF) of the ARINC661 standard, without considering the verification of the data structure of the ARINC661 standard during operation, so the verification is not comprehensive and cannot effectively guarantee the quality of equipment

Embodiment Construction

[0020] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] The test method in this embodiment realizes the comprehensive test of the ARINC661 cockpit display system by verifying and analyzing the definition file of the cockpit display system, and testing the run-time attributes of the components on the basis of the analysis. It mainly includes the verification and analysis of definition files, and the testing of runtime attributes.

[0022] 1. ARINC661 cockpit display system definition file verification. Load the definition file of the equipment (binary file in .BIN format), complete file analysis and verification from the file structure level and instruction level according to the ARINC661 standard, present the analysis results in a graphical manner, and save the verification results in the form of a report. ...

Abstract

The invention provides a cabin display system testing method based on the ARIINC 661 standard. A define file (DF file) based on the ARIINC 661 standard is analyzed at the file structure level and instruction level, the analysis result is displayed in an imaged mode, all components defined by the system and the hierarchical relation among the components can be seen clearly, the components are drawnin a figure form, and therefore correctness of the define file can be verified without products; attribute setting during component running is supported, and by means of interconnection with the system, product functions and performance are tested comprehensively. The cabin display system testing method completely conforms to ARIINC 661 standard, the current situation that the cabin display system testing method based on the ARIINC 661 standard only depends system integration tests to conduct verification, and system integration tests cannot expose all abnormal current situations; meanwhile,the cabin display system testing method is capable of supporting system debugging and fault locating and effectively improving system quality and has popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of testing and relates to a cockpit display system based on the ARINC661 standard, which is used to realize the comprehensive test, fault location and debugging of this type of cockpit display system. Background technique [0002] With the application of ARINC661 standard to military aircraft and the improvement of the comprehensiveness of military aircraft avionics system, the aircraft cockpit display system based on ARINC661 standard becomes more and more complex. However, the traditional aircraft cockpit display system detection is only realized by system joint test. Because the system joint test is difficult to carry out boundary test and abnormal test, the test process is not sufficient. As a result, it is difficult to fully test the aircraft cockpit display system only by system joint test. Effectively guarantee the quality of equipment. [0003] In addition, the existing tests are basically aimed at ...
