Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0030] The various non-limiting embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0031] Referring to FIG. 1, a system for testing an airborne data conversion unit according to an embodiment of the present application is shown. In this embodiment, the system includes a digital simulation environment module, an integrated test environment module, a real-time input / output module, and an airborne data conversion unit. The digital simulation environment module is connected to the integrated test environment module, and the integrated test environment module is connected to the airborne data conversion unit through the real-time input / output module. Figure 2 Specifically, the digital simulation environment module can be used to generate an ICD file according to a source ICD file in XML format. In this embodiment, the digital simulation environment can be based on an MBSE methodology and integrated with various system simulation and verification tools.
[0032] In one implementation, the digital simulation environment module can include an ICD conversion module and an ICD management module. The ICD conversion module can be used to identify a source ICD file in XML format and convert the source ICD file in XML format into the ICD file using an ICD conversion tool. That is, the digital simulation environment module can identify a source ICD file in XML format, run an ICD conversion tool, and obtain an ICD.ate file (i.e., an ICD file) to provide to the integrated test environment module as an integrated test constraint input.
[0033] The ICD management module can be used to manage and tailor the ICD according to the ICD file to obtain a processed ICD file. Specifically, after importing ICD data in standard XML format, the ICD management module can complete the management and tailoring of the ICD and generate a customized ICD file for the object under test.
[0034]
[0035] Specifically, the integrated test environment module is configured to manage the ICD according to the ICD file, determine the hardware test resource, connect with the aviation data conversion unit through the real-time input and output module, test the aviation data conversion unit, and collect the test result of the aviation data conversion unit.

[0042] In an implementation manner, the integrated test environment module includes a configuration management unit. The configuration management unit is configured to perform configuration management on the ICD and determine hardware test resources according to the operable engineering file. The operable engineering file can contain interface information of various bus and non-bus signals in the ICD, so that the configuration management on the ICD and the determination of the hardware test resources (i.e., binding of various signal interfaces and hardware test resources of the aviation data conversion unit) can be performed according to the operable engineering file. After the ICD interface and the hardware resource are configured, the test can be started, and finally the test and verification of the aviation data conversion unit are completed.

Based on the editable configuration ICD management, the management and editing of the signal interface during the testing process can be realized, and various testing configurations can be realized. Based on the test tool chain formed by the digital simulation environment module and the integrated test environment module, the data interaction based on the real-time network can be realized, and the testing command can be completed.

[0046] S302: An ICD file is generated according to the XML format source ICD file.
[0047] Specifically, the XML format source ICD file can be first converted into the ICD file by using an ICD conversion tool. Then, the ICD can be managed by cutting according to the ICD file, and a processed ICD file is obtained.
[0048] The interface data is configured by the digital simulation environment through the import of the XML format source ICD file of the aviation data conversion unit. After the rule check is completed without error, a platform ICD file that can be recognized by the integrated test environment is generated.
[0049] S303: The ICD is managed by configuration according to the ICD file, and hardware test resources are determined.
[0050] The ICD file is imported into the software engineering (i.e., a conversion program) of the integrated test environment to obtain an operable engineering file. The ICD can be configured and managed in the operable engineering file, and the interface information of various bus and non-bus signals in the ICD is included. In the operable engineering file, various signal interfaces of the airborne data conversion unit and hardware test resources are bound.
[0051] S304: Based on the configured ICD and hardware test resources, the airborne data conversion unit is tested, and the test results of the airborne data conversion unit are collected.
