真空熱試驗測控軟件系統(tǒng)架構設計

The software architecture design of measurement and control system in vacuum thermal tests

  • 摘要: 隨著航天器真空熱試驗的不斷增多,對真空熱試驗熱流模擬、溫度測量與控制系統(tǒng)的熱流模擬精度、速度、模式、測控通道數(shù)、系統(tǒng)功能等要求也越來越高。為進一步增強整個測控試驗流程的可靠性、安全性、易用性、可擴展性,縮短試驗準備時間,文章基于現(xiàn)有硬件系統(tǒng)與測控系統(tǒng)任務要求,提出了一套測控軟件系統(tǒng)架構設計,即采用自頂向下逐步細化的分層設計將整個系統(tǒng)軟件分層,再根據(jù)功能進行模塊劃分,保證了上層軟件的設備無關性與各模塊間的獨立性,能夠作為代碼并行開發(fā)的基礎,為代碼開發(fā)人員提供指導和限制。

     

    Abstract: With the increasing demand of vacuum thermal tests of spacecraft, the (temperature) measurement and the control system is required to expand its capabilities, including heat flux simulation accuracy, rate, modes, the number of channels, and system functions. In order to meet this development trend and enhance the reliability, security, usability, expansibility of software, this paper presents a new software architecture design of the measurement and control system based on the existing hardware resources and the system requirements. The hierarchical design and the module division in the architecture design are discussed in this paper. This architecture design can provide the code developers with sufficient guidance and restrictions, and serve as the foundation for concurrent code development.
