Modeling method for airborne product testing based on state machine

Abstract

The present invention provides a state machine-based airborne product testing modeling method, including the following steps: S1, determine all the signals used in the current test according to the cross-linking relationship of the tested product in the actual operating environment, and test the signal Carry out modeling to generate a test signal model; S2, model the airborne product architecture according to the airborne product schematic block diagram to generate an airborne product architecture model; S3, design a test scene based on the working scene according to the airborne product test requirements, and draw The test state machine obtains the test state machine model; S4, generates test cases. The application can make the design process more explicit and easy to understand, make the reuse of test information more convenient and flexible, and make the conformity evaluation of the airborne product test on the test requirement items more accurate, comprehensive and easy to read.

Description

technical field [0001] The invention relates to the field of product testing, in particular to an airborne product testing modeling method based on a state machine. Background technique [0002] At present, with the rapid development of domestic aviation technology, the complexity of airborne systems and equipment, the complexity of the operating environment, the complexity of signal cross-linking relationships, and the continuous improvement of system integration, the test logic of airborne products is increasingly complex, and the test requirements are becoming more and more difficult to track. Management, how to evaluate the test design scheme to meet the input test requirements, has become a problem that has to be considered when conducting airborne product testing; [0003] At the same time, with the gradual promotion of the model-based forward development model in the field of aviation equipment, product testing must match the new development model. After MBSE (Model-...

AI Technical Summary

Problems solved by technology

After MBSE (Model-Based Systems Engineering) was put forward, it solved the shortcomings and deficiencies of the document-based system engineering design method, such as inaccurate information representation, easy ambiguity, and difficulty in finding the required information from massive documents. The model method is more from the design point of view. There are many redundant information in each model that cannot be used in the test, resulting in low test case design efficiency and complex configuration when the test case is executed in the test system.
