摘要: 真空熱試驗是衛(wèi)星研制過程中必須進行的大型地面模擬試驗之一。在真空熱試驗的準備階段和試驗階段都必須采集衛(wèi)星南北板傾斜角度，密切關注衛(wèi)星姿態(tài)，以判斷熱管是否處于正常工作狀態(tài)。文章基于AT89C52單片機、TSD-232水平敏感器和C語言設計出一套衛(wèi)星水平度測量系統(tǒng)，并對其在Keil u Vision3和Proteus聯(lián)合平臺下進行了仿真分析。結果表明：該系統(tǒng)結構簡單，程序設計方便，為衛(wèi)星水平度的實時監(jiān)測提供了保障。Abstract: The vacuum thermal test of spacecraft is one of the most important ground tests for spacecraft. To ensure the normal working state of heat pipes, the inclining angle of spacecraft should be monitored, in order to judge the working state of heat pipes. This paper presents the design of a measurement system for the inclining angle of spacecraft based on AT89C52, TSD-232 and C language, and the system is simulated by using Keil uVision3 and Proteus unite software system.
