Design and implementation of data visual system in spacecraft vacuum thermal test

摘要: 針對航天器真空熱試驗測控數(shù)據(jù)處理現(xiàn)狀和需求，通過引入三維數(shù)據(jù)可視化技術(shù)，設(shè)計了一種數(shù)據(jù)可視化系統(tǒng)。該系統(tǒng)運用Java 3D技術(shù)，通過虛擬場景設(shè)定，將真空熱試驗試件三維設(shè)計模型與熱模型結(jié)合，實現(xiàn)溫度數(shù)據(jù)—顏色映射，以云圖形式顯示測控數(shù)據(jù)，并實現(xiàn)與現(xiàn)有測控軟件數(shù)據(jù)交互。典型試驗結(jié)果表明：該可視化系統(tǒng)可以實時、真實、直觀地顯示試件在真空熱試驗過程中的溫度變化情況，為試驗過程中的實時溫度監(jiān)視和工況判讀提供有效手段。

Abstract: A three-dimensional data visualization display system for spacecraft vacuum thermal tests is designed by using Java 3D and by setting a virtual scene. The system combines the 3D model of the spacecraft with the thermal model, making the temperature data displayed in the form of cloud images through a color mapping, and the data exchange is realized with existing monitoring and control software. The typical experimental results show that this system can display the online test temperature not only visually but also accurately.
