Description

Reverse Automatic Modeling Method of Bus Structure Used in Matlab Automatic Test

Technical field:

The invention belongs to the field of automatic testing of aeroengine control law models.

Background technique:

At present, there are more and more automatic model testing applications based on Matlab. Model automatic simulation testing plays a very important role in the development and verification of the V process. Any development (including model development) process, as long as someone intervenes, there must be various All kinds of mistakes, therefore, the role of simulation and testing is very important, and it plays the role of the final check. V&V refers to Validation and Verification. First, we must do things correctly, and then verify whether we have done the right thing.

In the process of model automatic testing and verification, a very important part is to generate the tested Harness model. Since the models themselves are various, how to analyze all the models and then automatically generate the tested model is very important. Both the top-level model and the models in the middle layers must use the Bus structure. Therefore, the analytical model will encounter the analysis of the Bus structure, because the Bus structure is also complex and varied. And the most important thing is that all versions of Matlab on the market are not very good at identifying the Bus structure. When generating the tested model Harness, it cannot automatically analyze and generate the input and output signals containing the Bus structure. By modifying the model, removing the Bus structure, or simplifying the Bus structure, the Harness model can be generated. Therefore, the technology of analysis and reverse automatic modeling of the Bus structure is related to the success or failure of automatic testing. If the analysis and reverse automatic modeling technology for all Bus structures is solved, then the model automatic testing will be really applied.

Invention content:

Purpose of the invention: the present invention provides a kind of Bus structure reverse automatic modeling method that is used for Matlab automatic test.

Technical solutions:

A reverse automatic modeling method of Bus structure for Matlab automatic testing. include:

1) Automatically collect test case data in EXCEL files;

2) Automatically read the model under test, find all the input and output terminals in the model under test, and distinguish which input and output terminals contain BUS structures and which input and output terminals do not contain BUS structures;

3) For the input and output terminals containing the BUS structure, read the BUS structure contained in it, use the multi-fork tree preorder traversal algorithm, analyze the number and name of each Bus structure layer by layer, and record each BUS structure at the same time The path and name of the leaf nodes in the body are stored in the cache array;

4) According to the path and name in the cache array, starting from the root node, reverse automatic modeling layer by layer, until all the leaf nodes;

5) Encapsulate the model after automatic reverse modeling, and output it as a Harness model that can be automatically tested in the Matlab environment.

Beneficial effect:

After adopting the present invention, various complex Bus structures can be fully automatically identified. Through a large number of tests and verifications, the model can be completely and automatically established according to the reverse of the Bus structure hierarchy, and the connection relationship is correct, and the compilation is passed. Meet all the requirements of automatic testing. The manpower is liberated, and the defect that the Harness model to be tested must be manually established when using the matlab tool for testing is solved.

detailed description

A reverse automatic modeling method of Bus structure for Matlab automatic testing. As shown in Figure 1, including:

1) Test case reading: automatically collect test case data in EXCEL files;

2) Model reading: automatically read in the model under test, search for all input and output terminals in the model under test, and identify which input and output terminals contain BUS structures and which input and output terminals do not contain BUS structures;

3) Traversing and analyzing the BUS structure: For the input and output terminals containing the BUS structure, read in the BUS structure contained in it, and use the multi-fork tree preorder traversal algorithm to analyze the number and name of each Bus structure layer by layer, At the same time, record the path and name of the leaf nodes in each BUS structure and store them in the cache array;

4) Automatic reverse modeling: According to the path and name in the cache array, starting from the root node, reverse automatic modeling layer by layer until all leaf nodes;

5) Automatically encapsulate the Harness model: encapsulate the model after the automatic reverse modeling, automatically set the relevant attributes of all input and output terminals, and finally output the Harness model that can be automatically tested in the Matlab environment.

The compilation process of the software part of the inventive method is as follows:
