Abstract

In this paper, a novel intelligent monitoring system based on digital twin framework is developed for spacecraft vacuum thermal test. More precisely, the corresponding digital twin model mapping of real-world spacecraft vacuum thermal test is constructed by hierarchy design scheme with robustness. Then, in order to reliably obtain all the dynamical data during the entire vacuum thermal testing processes, the monitoring system is designed with hardware equipment and software integration. As a result, the testing data analysis, fault detection and decision optimization for spacecraft vacuum thermal test can be achieved, which can effectively save the implementation cost and improve the testing efficiency. In the end, the practical experiment case is presented for showing the usefulness of the designed intelligent monitoring system.
