Cabin display system testing method based on ARIINC 661 standard

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 ...

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
