Description

Technical Field

[0001] The present application relates to the field of satellite detection, and in particular to a method and device for detecting a satellite ground cabin plate, a test device and a storage medium. Background Art

[0002] With the rapid development of communication technology and central processing units, satellite products have begun to change from the original high-orbit, large satellite-dominated to small satellite constellations, such as the Iridium constellation, OneWeb constellation, and Starlink constellation. The number of satellites has developed from the traditional number of satellites to hundreds, thousands, and even tens of thousands. For example, Space-X's Starlink project has a total of more than 40,000 satellites, and currently produces 120 satellites per month. This has challenged the traditional satellite development model and development capabilities. The development cycle of traditional satellites is 5 to 10 years, and that of small satellites is as long as 2 to 3 years, which cannot meet the development needs of current and future constellation plans. The development of satellites is divided into three stages: AIT (assembly, integration, testing, and experimentation). Among them, as the most important test and experimentation stage, its key proportion and time proportion in satellite development are particularly important.

[0003] In the process of conceiving and realizing this application, the inventors found that there are at least the following problems: in the development of traditional satellites, the test system is aimed at one satellite per test. How to ensure that the number of satellites developed is increased and the development cycle is greatly shortened; how to use limited resources for batch testing.

[0091] In one embodiment, the detection method further comprises:

[0092] S60: When a single test fails for a preset number of consecutive times, the test returns to the initial state and the detection method is re-executed.

[0093] By using the secondary confirmation method, the misjudgment of the star installation test can be avoided, and the process efficiency can be improved. Optionally, the present application does not limit the preset number of times. Generally, when a single test fails three times in a row, it returns to the initial state. It can also be set to four, five or other preset times.
