Problems solved by technology
At present, in terms of acceptance and testing of on-board computers, it mainly relies on manual debugging; due to the low efficiency of manual debugging and high dependence on manual experience, the acceptance and testing of on-board computers takes a long time. Difficult to test and accept a large number of onboard computers
At the same time, with the further shortening of the space vehicle development cycle and the highly integrated development of the spaceborne computer, the contradiction between the low test efficiency of the spaceborne computer and the high acceptance of large-scale testing has become increasingly prominent.

The invention discloses a satellite-borne computer automatic test method and system. The method comprises the steps of inputting a preset test script; generating a control instruction according to thepreset test script; sending the control instruction to embedded test software so as to test the satellite-borne computer to be tested; receiving a test result of the satellite-borne computer to be tested; and performing data analysis on the test result to generate a test report of the satellite-borne computer to be tested. According to the invention, the satellite-borne computer can be automatically tested according to the functional requirements of the spacecraft or the test requirements of the satellite-borne computer in the spacecraft, the test efficiency of the satellite-borne computer isremarkably improved, and the development period of the spacecraft is greatly shortened.
Description
technical field [0001] The invention relates to the technical field of on-board computer testing in the aviation field, in particular to a method and system for automated testing of on-board computers. Background technique [0002] With the rapid development of the national aerospace industry, the number of space vehicles is increasing year by year, the functions are becoming more and more complex, and the design life is also increasing. At the same time, the development process of space vehicles has been greatly accelerated. However, due to the different functional requirements of different space vehicles, the hardware and software designs of the onboard computers of each space vehicle are also different. The differences between different onboard computers mainly exist in the aspects of CPU model, communication interface and data processing chip; among them, the commonly used CPU models of onboard computers mainly include TSF695 processor, BM3803 processor, ATF697 processor...
