Description

Technical Field

[0001] This invention relates to a general testing method and system for spacecraft based on a hybrid nesting of general templates, belonging to the field of spacecraft system integration and verification. Background Technology

[0002] Spacecraft system testing, as a crucial component of spacecraft system integration and verification, bears the important responsibility of ground verification of spacecraft system design and on-orbit operational capability verification. The quality of system testing directly affects the spacecraft's on-orbit performance and operational status.

[0003] Because a spacecraft system is a highly complex and large-scale system, both hardware and software design integrate the system designers' thorough consideration and research on the normal operation of the spacecraft in orbit. Therefore, comprehensive, complete, efficient, and accurate system testing places higher demands on test personnel. Due to significant differences in the functions and designs of different spacecraft, the methods, modes, and operating conditions for system testing also vary. This brings immense workload and pressure to test personnel.

[0004] Current testing methods involve cumbersome manual operations. System testing under complex conditions requires testers to perform repetitive tasks, which seriously affects tester efficiency and exposes them to the risk of human error. Summary of the Invention

[0005] The technical problem solved by this invention is: addressing the shortcomings of existing technologies, this invention proposes a general spacecraft testing method based on a hybrid nesting of general templates. By designing a general system test template, it enables the hybrid nesting of different models and designs of systems to automate system testing. From multiple dimensions such as command transmission, data interpretation, and logical timing, it improves the effectiveness of system testing, increases testing efficiency, reduces the risk of human error, ensures the progress and quality of spacecraft development, and supports the safe and stable operation of spacecraft in orbit.

[0006] The present invention solves the above-mentioned technical problem through the following technical solution:

[0007] A general spacecraft testing method based on a hybrid nested general template includes:

[0008] Based on the system design input, clarify the system testing requirements, screen the common elements of the system testing items, and design a general test sequence execution template;

[0009] The obtained general test sequence execution template is used to perform mixed nesting for different test requirements, test items and test conditions, forming test rules based on mixed nesting of general templates and quantifying requirement indicators, and setting corresponding execution conditions and execution result criteria for each test item;

[0010] The obtained test details are divided according to the execution conditions of each test item, and standardized in terms of time and event dimensions to form test instructions for test items. The test results are directly linked to the test instructions to improve the effectiveness of the test.

[0011] For the obtained test results and test data, review the test details and test instructions, judge the correctness and validity of the data, and verify whether the test results meet the test requirements to reduce the risk of misjudgment.

[0012] Furthermore, the general test sequence execution template is formulated based on the minimum test items, with execution conditions, execution time, execution instructions, and execution results as common elements of the test template.

[0013] Furthermore, the specific method for generating test details by mixing and nesting general templates is as follows:

[0014] The logical relationship between test templates can be parallel or serial. Under the test project with the largest envelope, it is subdivided into multiple sub-test projects defined by general templates. In each sub-test project, the executed instruction is a single instruction or a set of multiple instructions or a set of general templates. Through the mixed nesting of templates and instructions, a complete test sequence is gradually built.

[0015] Furthermore, the execution conditions for the general template are designed, specifically by designing the template execution conditions from two dimensions: time and event. The elements include:

[0016] The absolute time relative to the start time of the entire test project;

[0017] Should the judgment criteria for the results of the previous test item continue to be executed?

[0018] After a certain state variable changes, determine whether the test item should be executed;

[0019] Execute unconditionally.

[0020] Furthermore, the execution conditions determine whether the test item is executed, the execution time determines the start time of the test template, the execution instructions determine the specific operations under the test item, and the execution result criteria determine whether the test results of the test item meet the test requirements or expectations, and can become the execution conditions of other test templates.

[0021] A universal spacecraft testing system based on a hybrid nested general template includes:

[0022] General Test Sequence Execution Template Generation Module: Based on the system's design input, clarify the system testing requirements, select common elements of the system testing items, and design a general test sequence execution template;

[0023] General Test Sequence Execution Template Combination Module: The obtained general test sequence execution template is mixed and nested for different test requirements, test items and test conditions to form test rules based on the mixed nesting of general templates and quantify the requirement indicators, and set the corresponding execution conditions and execution result criteria for each test item;

[0024] The general test sequence execution instruction generation module: Based on the execution conditions of each test item, the obtained test details are standardized and designed from the two dimensions of time and event to form test instructions for the test items. The test results are directly associated with the test instructions to improve the effectiveness of the test.

[0025] Test structure judgment module: Review the test results and test data, verify the test details and test instructions, judge the correctness and validity of the data, and verify whether the test results meet the test requirements to reduce the risk of misjudgment.

[0026] The advantages of this invention compared to the prior art are:

[0027] (1) The present invention proposes a spacecraft general test method based on general template hybrid nesting, which can realize the standardization, unification and generalization of large and complex system test work and improve the effectiveness of system test;

[0028] (2) This invention simplifies the testing process by configuring the test sequence according to different working conditions and projects, and directly associates the data results with the test execution conditions to ensure the effectiveness of the test, improve the test efficiency, and reduce the risk of human error.

[0031] Figure 3 A hybrid nesting method based on a general test template is provided for the invention. Detailed Implementation

[0032] The specific solution of the present invention will now be described with reference to the accompanying drawings.

[0033] A general spacecraft testing method based on a hybrid nested general template is proposed. This method establishes a framework by mining common elements of test items, such as... Figure 2 The generalized test sequence execution template shown can be nested and mixed to handle different test tasks, as follows: Figure 3 As shown, a generalized test solution is implemented to handle different test tasks. For the "normal simulated flight of a spacecraft" test condition, such as... Figure 1 As shown, the specific steps are as follows:

[0034] (1) Based on the system design input, clarify the system testing requirements, screen the common elements of the system testing items, and design a general test sequence execution template. The general test sequence template is as follows: Figure 2 :

[0035] Test templates are designed based on the smallest test items. Execution conditions, execution time, execution instructions, and execution results are common elements of test templates. Among them, execution conditions determine whether the test item is executed, execution time determines the start time of the test template's operation, execution instructions determine the specific operations under the test item, and execution results and criteria determine whether the test results of the test item meet the test requirements or expectations, and can become the execution conditions for other test templates.

[0037]

[0038] (2) Execute the general test sequence template obtained in step (1), and perform mixed nesting for different test requirements, test items, and test conditions to form test details based on the mixed nesting of the general template, quantify the requirement indicators, and set corresponding execution conditions and execution result criteria for each test item. For the "spacecraft normal simulated flight" test condition, the specific method for generating test details by mixed nesting of the general template is as follows: Figure 3 :

[0039] The logical relationships between test templates can be parallel or sequential. Under the largest envelope of test items, multiple sub-test items defined by general templates can be further subdivided. In each sub-test item, the executed instruction can be a single instruction, a set of multiple instructions, or a set of general templates. A complete test sequence is gradually built through the mixing and nesting of templates and instructions. Different test items and operating conditions can be achieved through the combination and nesting of different templates, facilitating systematic testing and also benefiting the work of the subdivided sub-test items.

[0040] By analyzing the "spacecraft normal simulated flight" test conditions, the following general templates can be formed: ground equipment initial state setting template, system initial power-on setting template, on-board component state initial setting template, time synchronization template, component selection template, active phase exhaust setting template, satellite-launch separation setting template, normal mode ground-to-space setting template, on-board component state setting template, spacecraft mode setting template, attitude maneuvering template, orbital maneuvering template, antenna setting template, system power-off setting template, etc. Each type of template is shown in Table 1. By mixing and nesting different templates, different test requirements can be achieved, as shown in the following table:

[0041] Table 2. Test Details for Mixed Nesting of General Templates

[0042]

[0043] (3) Based on the test details obtained in step (2), and according to the execution conditions of each test item, standardize the design from the two dimensions of time and event to form test instructions for the test items. Directly link the test results with the test instructions to improve test effectiveness. The template execution conditions are designed from the two dimensions of time and event, with the following elements:

[0044] 1) The absolute time relative to the start time of the entire test project;

[0045] 2) Should the judgment conditions for the results of the previous test item continue to be executed?

[0046] 3) A change in a certain state variable determines whether the test item should be executed;

[0047] 4) Execute unconditionally.

[0048] The design of execution conditions directly links test results to test instructions, ensuring the effectiveness, continuity, and accuracy of test projects even without human intervention.

[0049] For the various test conditions shown in Table 2, the test instructions generated autonomously based on the general template hybrid nesting are shown in the following table:

[0052]

[0053] (4) Review the test results and test data obtained in step (3), check the test details and test instructions, judge the correctness and validity of the data, and check whether the test results meet the test requirements to reduce the risk of misjudgment.
