Description

Technical Field

[0001] This invention relates to the field of airborne high-speed bus testing technology, and in particular to an airborne high-speed bus testing system. Background Technology

[0002] Airborne products refer to equipment, systems, or components installed on aircraft (such as airplanes, helicopters, and drones) to support flight, navigation, communication, mission execution, or passenger services. Before airborne products are applied, they need to undergo functional and performance testing.

[0003] With the increasing integration and intelligence of airborne products, the amount of data exchange is growing, making the 1394B bus a crucial interface for data exchange between the flight control system and various airborne products. Therefore, before conducting functional and performance tests on individual airborne products, it is essential to ensure the accuracy of data exchange between the flight control system and the airborne products; that is, to first conduct airborne high-speed bus testing.

[0004] Currently, airborne high-speed bus test systems are typically customized for airborne products. If the airborne product model remains unchanged or is not upgraded or replaced, these systems can be used indefinitely. However, during the development of this application, the inventors discovered that airborne products experience frequent changes to their bus interface control protocols during the design and development phase, and testing time is tight. When the bus interface control protocol changes, the software source code of the airborne high-speed bus test system needs to be modified simultaneously for software adaptation and iterative upgrades before it can be used. However, the software version upgrade cycle of the airborne high-speed bus test system is long, and frequent software upgrades lead to low efficiency, making it difficult to meet the high-speed bus testing requirements of airborne products during the design and development phase. Summary of the Invention

[0005] This invention provides an airborne high-speed bus testing system to address the problem that current airborne high-speed bus testing systems are too inefficient and cannot meet the high-speed bus testing requirements of airborne products during the design and development phase.

[0006] In a first aspect, embodiments of the present invention provide an airborne high-speed bus testing system, comprising: a bus database template, a bus user interface library, a bus encoding / decoding logic library, a bus database update module, and a system loading module;

[0007] The bus database update module is used to generate a target bus interface control protocol database for the airborne product under test based on the current version bus data information of the airborne product under test and the bus database template.

[0008] The system loading module is used to load the target bus interface control protocol database, the bus user interface library, and the bus codec logic library to obtain the target airborne high-speed bus test system for the airborne product under test.

[0009] In one possible implementation, the process of determining the bus database template includes:

[0010] Iterate through all data types and configuration information of the high-speed bus of the airborne product under test;

[0011] Based on all data types and all configuration information, the bus database template is defined.

[0012] In one possible implementation, the process of determining the bus user interface library includes:

[0013] Based on all data types and all configuration information, the largest set of data types is selected to equip the encoding control template and parsing control template, thus obtaining the bus user interface library.

[0014] In one possible implementation, the process of determining the bus codec logic library includes:

[0015] Based on all data types and all configuration information, encoding and decoding logic for all data types are generated to obtain the bus encoding / decoding logic library.

[0016] In one possible implementation, the bus database update module is specifically used for:

[0017] Based on the bus database template, generate the previous version bus interface control protocol database of the airborne product under test.

[0018] Based on the differences between the current version bus data information and the previous version bus data information of the airborne product under test, the bus interface control protocol database of the previous version is modified to generate the target bus interface control protocol database of the airborne product under test.

[0019] In one possible implementation, the bus database update module is specifically used for:

[0020] The bus database template is used to decompose the current version bus data information of the airborne product under test, and the target bus interface control protocol database of the airborne product under test is generated based on the decomposition results.

[0021] Secondly, embodiments of the present invention provide an airborne high-speed bus testing method, including:

[0022] Based on the current version bus data information and bus database template of the airborne product under test, generate the target bus interface control protocol database of the airborne product under test.

[0023] The target bus interface control protocol database, bus user interface library, and bus codec logic library are loaded to obtain the target airborne high-speed bus test system for the airborne product under test.

[0024] The high-speed bus data transmission of the airborne product under test is tested based on the target airborne high-speed bus test system.

[0025] Thirdly, embodiments of the present invention provide an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the method described in the second aspect above.

[0026] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the method described in the second aspect above.

[0027] Fifthly, embodiments of the present invention provide a computer program product, including a computer program that, when executed by a processor, implements the method described in the second aspect above.

[0028] In this embodiment of the invention, a bus database template, a bus user interface library, a bus codec logic library, a bus database update module, and a system loading module are set up. The bus database update module generates a target bus interface control protocol database for the airborne product under test based on the current version bus data information and the bus database template. The system loading module loads the target bus interface control protocol database, the bus user interface library, and the bus codec logic library to obtain a target airborne high-speed bus test system for the airborne product under test. After modifying the bus interface control protocol of the airborne product under test, only the target bus interface control protocol database needs to be generated based on the current version bus data information of the airborne product under test to obtain a synchronously modified target airborne high-speed bus test system. There is no need to modify the software source code of the airborne high-speed bus test system, thereby improving testing efficiency and meeting the high-speed bus testing requirements of airborne products in the design and development stage.

[0034] Figure 6 This is a schematic diagram of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] See Figure 1 The diagram illustrates an airborne high-speed bus testing system provided in an embodiment of the present invention, including: a bus database template 10, a bus user interface library 20, a bus encoding / decoding logic library 30, a bus database update module 40, and a system loading module 50.

[0037] The bus database update module 40 is used to generate a target bus interface control protocol database for the airborne product under test based on the current version bus data information of the airborne product under test and the bus database template 10.

[0038] The system loading module 50 is used to load the target bus interface control protocol database, the bus user interface library 20, and the bus encoding and decoding logic library 30 to obtain the target airborne high-speed bus test system for the airborne product under test.

[0039] Among them, combined Figure 2 As shown, a typical airborne high-speed bus test system is equipped with a 1394B bus excitation acquisition unit, which can provide control information simulation and bus data parsing for airborne products, completing the bus interconnection function test of airborne products. The process begins with initializing the 1394B (i.e., AIR5654) bus configuration, configuring the bus encoding and parsing logic. When receiving data, the system refreshes the data, then reads and parses the bus data, and refreshes the UI status. When sending data, the system acquires the UI status, then encodes the bus data and sends the bus data.

[0040] However, when the bus interface control protocol changes, the software source code needs to be modified to adapt to the new bus data encoding and parsing logic, and a new software version needs to be released before the bus function testing of airborne products can be carried out. Figure 3 As shown.

[0041] This application, by setting up a bus database template, a bus user interface library, a bus codec logic library, a bus database update module, and a system loading module, can modify the 1394B interface control protocol database when the bus interface control protocol changes, and then load the new version of the database to perform bus function testing on the new version of the airborne product. Figure 4 As shown.

[0042] This invention establishes a bus database template, a bus user interface library, a bus codec logic library, a bus database update module, and a system loading module. The bus database update module generates a target bus interface control protocol database for the airborne product under test (TBD) based on the current version of the TBD's bus data and the bus database template. The system loading module loads the target bus interface control protocol database, the bus user interface library, and the bus codec logic library, resulting in a target high-speed airborne bus test system for the TBD. This allows for modifications to the TBD's bus interface control protocol; simply generating the target bus interface control protocol database based on the current version of the TBD's bus data is sufficient to obtain a synchronously modified target high-speed airborne bus test system. No modification to the TBD's high-speed airborne bus test system's software source code is required, thereby improving testing efficiency and meeting the high-speed bus testing needs of airborne products during the design and development phase.

[0043] Optionally, the process of determining the bus database template 10 may include:

[0044] Iterate through all data types and configuration information of the high-speed bus of the airborne product under test.

[0045] Based on all data types and all configuration information, bus database template 10 is defined.

[0046] Optionally, the process of determining the bus user interface library 20 may include:

[0047] Based on all data types and all configuration information, the largest set of data types is used to equip the encoding control template and parsing control template to obtain the bus user interface library 20.

[0048] Optionally, the process of determining the bus codec logic library 30 may include:

[0049] Based on all data types and all configuration information, encoding and decoding logic for all data types is generated, resulting in bus encoding / decoding logic library 30.

[0050] Optionally, the bus database update module 40 is specifically used for:

[0051] Based on bus database template 10, generate the previous version bus interface control protocol database of the airborne product under test.

[0052] Based on the differences between the current version bus data information and the previous version bus data information of the airborne product under test, the bus interface control protocol database of the previous version is modified to generate the target bus interface control protocol database of the airborne product under test.

[0053] Specifically, an initial bus interface control protocol database for the airborne product under test (TBD) can be generated based on its initial version bus data and bus database template. The initial version bus data is then recorded as the previous version bus data, and the initial bus interface control protocol database is also recorded as the previous version bus interface control protocol database. When a new version bus data is available, it is used as the current version bus data for the TBD. Based on the differences between the current and previous version bus data, the previous version bus interface control protocol database is modified to generate the target bus interface control protocol database for the TBD.

[0054] When a second new version of bus data information is available, it is used as the current version of the bus data information for the airborne product under test. At this time, the previous version of bus data information is the same as the first new version of bus data information, and the previous version of bus interface control protocol database is the target bus interface control protocol database corresponding to the first new version of bus data information. Then, the process of "modifying the previous version of bus interface control protocol database according to the difference between the current version of bus data information and the previous version of bus data information of the airborne product under test, and generating the target bus interface control protocol database of the airborne product under test" is continued. This process obtains the target bus interface control protocol database corresponding to the current version of bus data information of the airborne product under test, so as to improve testing efficiency and meet the high-speed bus testing requirements during the design and development stage of the airborne product.

[0055] Optionally, the bus database update module 40 is specifically used for:

[0056] Based on the bus database template 10, the current version bus data information of the airborne product under test is decomposed, and the target bus interface control protocol database of the airborne product under test is generated based on the decomposition results.

[0057] This embodiment provides another method for generating the target bus interface control protocol database. When the current version bus data information of the airborne product under test changes significantly, the current version bus data information of the airborne product under test can be directly decomposed according to the bus database template 10, and the target bus interface control protocol database of the airborne product under test can be generated according to the decomposition result, so as to generate the target bus interface control protocol database corresponding to the current version bus data information of the airborne product under test more efficiently and quickly.

[0058] For example, the data types of the high-speed bus of the airborne product under test can include integer data, enumerated data, Boolean data, floating-point numbers, etc. Configuration information can include byte offsets, word offsets, bit lengths, signal names, signal IDs, physical ranges, units, data values, truth definitions, etc., corresponding to different data types. The bus database template 10 can include templates for different data types and their corresponding configuration information. When decomposing the current version bus data information of the airborne product under test according to the bus database template 10, assuming the current version bus data information includes integer data and its corresponding configuration information, and enumerated data and its corresponding configuration information, the templates corresponding to integer data and enumerated data in the bus database template 10 can be matched. Therefore, according to the templates corresponding to integer data and enumerated data, a database corresponding to the current version bus data information is generated, which is the target bus interface control protocol database of the airborne product under test.

[0059] For example, the following specific examples illustrate the working process of the airborne high-speed bus testing system provided in the embodiments of the present invention:

[0060] Step 1: Traverse all data types and configuration information of the 1394B bus.

[0061] Step 2: Based on all the data types and configuration information obtained in Step 1, define a database template containing all bus configuration information to obtain 1394B bus database template result 1.

[0062] Step 3: Based on the 1394B bus database template result 1 obtained in Step 2, decompose the bus data information of the current version of the airborne product, enter it into the database, and obtain the 1394B bus interface control protocol database result 2.

[0063] Step 4: Based on all the data types and configuration information obtained in Step 1, develop a general display UI, take the largest set of data types, equip it with encoding and parsing control templates, and obtain the 1394B bus UI library result 3.

[0064] Step 5: Based on all data types and configuration information obtained in Step 1, develop the encoding and decoding logic for all data types to obtain the 1394B encoding and decoding logic library result 4.

[0065] Step 6: Based on the 1394B bus UI library result 3 obtained in Step 4 and the 1394B encoding and decoding logic library result 4 obtained in Step 5, perform software integration to obtain the 1394 bus custom test software result 5. That is, after integration, a 1394B bus test software is obtained (that is, the system loading module loads the 1394B bus interface control protocol database result 2, the 1394B bus UI library result 3 and the 1394B encoding and decoding logic library result 4 to obtain the 1394B bus test software).

[0066] Step 7: Obtain the modified bus data information of the new version of the airborne product.

[0067] Step 8: Based on the bus data information of the new version of the airborne product obtained in Step 7, modify the 1394B bus interface control protocol database result 2 (i.e., the first version of the bus interface control protocol database V1) to obtain the 1394B bus interface control protocol database result 6 (i.e., the second version of the bus interface control protocol database V2); modify the data according to the differences between the bus data information of the new version of the airborne product and the bus data information of the current version of the airborne product, without changing the software.

[0068] Step 9: Based on the 1394B bus interface control protocol database result 6 (i.e., V2) obtained in Step 8, load the 1394 bus custom test software result 5 obtained in Step 6. The software will automatically adapt the controls according to the modified protocol to obtain the new version of the 1394 bus custom test software result 7 (the software has pre-edited the controls for all signal types, and can automatically adapt and display them according to the data type flags in the loaded database).

[0069] Step 10: Click to obtain the new version of the 1394 bus custom test software result 7 according to step 9. Select different data content through the UI interface to send and receive bus data, and realize the 1394B bus function test of the bus data information of the new version of the airborne product.

[0070] The airborne high-speed bus testing system provided in this embodiment of the invention can complete the version upgrade of the airborne high-speed bus testing system simply by modifying the database and reloading it, without modifying the software source code for software upgrades and releases. This can meet the requirements of rapid adaptation when the bus interface control file changes and improve testing efficiency.
