Embodiment Construction

[0019] It should be understood that the automatic satellite ground test curve interpretation method of the present invention includes test curve feature extraction, interpretation criterion formulation, basic interpretation algorithm compilation, and algorithm implementation during the test process. The steps of the specific test process are as follows:

[0020] Before the test is implemented, the extraction of the test curve features is completed. Firstly, the curves generated during the satellite testing process are classified, the main features of different types of curves are extracted, and the features are quantitatively analyzed.

[0021] Then, sort out the ground test curves of the previous satellites of the same platform, or the test curves that have been completed in the previous stage of the satellite to be tested, find the distribution range of the main characteristics of the test curves corresponding to different test items, and formulate a correctness interpretati...

Abstract

The invention provides a curve data automation interpretation method which is used for carrying out automation interpretation on correctness of a test curve generated during a satellite test process. The method comprises the following steps of extracting main characteristics of different types of curves generated during a curve satellite test process in advance and carrying out quantitative analysis on the main characteristics of the curves; arranging the different types of curves and finding a distribution scope of the main characteristics of the curves so as to make an interpretation criterion; using a predetermined scripting language to compile an algorithm used by a curve determination criterion and integrating to a ground automation test module so as to execute the interpretation; and through taking the curve ground automation test module, carrying out automatic interpretation on the curve to be tested. Therefore, by using the method, interpretation efficiency can be increased, an interpretation method is extendable, covering performance to different types of the tested curves is good, an advantage of the scripting language can be fully used, and the method is easy and simple and has good transportability. Besides, the method possesses good adaptability to the interpretation of the curve whose characteristic is not easy to extract.

Description

technical field [0001] The present invention is applicable to the field of spacecraft ground testing, in particular relates to the automatic interpretation of test curves in the ground testing process of communication satellites, and more specifically relates to a curve used for automatic interpretation of the correctness of the test curves generated in the satellite testing process Data automatic interpretation method. Background technique [0002] During the satellite ground test process, the telemetry of the satellite equipment or the ground test equipment itself will generate a large amount of test data, most of which are functions of time, and form different curves within a given test time. The range, shape and other characteristics of the curve are a reflection of the function and performance of the satellite. Therefore, the interpretation of the curve data is an important means to judge the functions and technical indicators of the satellite in the process of satellit...
