基于统一建模语言(UML)的航天器真空热试验测控系统电气建模

摘要

随着航天器批量化生产及新型号研制进程加快,航天器真空热试验需求越来越多样,试验温度测量与控制的复杂程度越来越高,现有测控系统逐渐暴露出固有缺陷.文章针对测控电气系统,基于统一建模语言(UML)分析并提出了系统模型,提高了试验设备信息的处理能力,增强了系统设计人机交互的规范性,改进了试验进行时状态跟踪效果.通过实际的案例应用,展示了通过电气模型提高试验可靠性的过程.%With the bulk and scale production of spacecraft and the accelerated proces;s of the new model development,the spacecraft vacuum thermal tests are required in more and more diverse conditions.For example,the temperature measurement and control is becoming more and more complicated,and the existing system gradually shows its inherent inadequacy.This paper focuses on the measurement and control electrical system,based on the united modeling language(UML) analysis and a system model is proposed to increase the information processing capability of the test equipment,to enhance the system design human-computer interaction level,and thus to improve the state tracking functions during the test.It is demonstrated through the actual case application that the reliability of the test is enhanced by the electric model.
