Description

technical field [0001] The patent of the present invention relates to the field of space satellite test data simulation, and mainly relates to a test data simulation method and system that can flexibly customize the frame format. Background technique [0002] With the advancement of aerospace technology, the functions of various satellites are becoming more and more diverse and complex, and the satellite ground test technology is also gradually developing towards generalization. Especially in the test of satellite data transmission system and fixed storage system, ground test equipment needs to generate test data that meets the requirements according to the frame format defined by the system to simulate the real environment for system testing. Such equipment is called data simulation equipment. For different stand-alone systems, the data frame format and interface type are completely different. Therefore, the development of a data simulation device with a flexible frame form...

AI Technical Summary

Problems solved by technology

In complex test scenarios with multiple interface types and multiple data formats, multiple test devices need to be used in combination, which increases the complexity of the test system

Therefore, the existing test data simulation equipment cannot flexibly modify the data frame format and interface type, the degree of generalization is low, the test data transmission speed is slow, and the test method cannot be customized and modified.
