Abstract
Model-based testing is an important direction of test automation research, the autonomous thermal control function of spacecraft is relatively solidified, the principle is relatively simple, and the test method of autonomous thermal control is universal. In this paper, the autonomous thermal control function of the thermal control subsystem of a deep space probe is selected as the research object. Firstly, the modeling process is introduced. Secondly, the two important links in the modeling process, strategy classification and model definition are described in detail. Finally, an example and the verification results of modeling correctness are given. The result of this model design will greatly shorten the time of test preparation and test implementation, and reduce the test cost. The results of research have great support and reference significance for the common generation selection test in deep space field and the design and implementation of model-based test in other fields.
