摘　　要：随着航天器结构与热设计复杂性的提升,结构表面测温工艺实施难度增大,测温区域趋于多元化,对航天器热试验中非接触测温技术的应用需求日益增多。以红外测温设备在真空、高低温环境中的应用为研究对象,对设备热防护方案与装置进行设计,并基于节点网络法对红外测温设备热防护进行仿真分析,通过物理试验验证,该防护装置能够有效实现设备在真空、高低温环境中热防护,确保设备处于正常工作温度区间且其测温算法模型不受影响,测温准确度优于±2℃,满足设备在空间环境试验中的使用需求。With the increasing complexity of spacecraft structure and thermal design,it is more difficult to implement surface temperature measurement technology,and the temperature measurement area tends to diversify.Therefore,there is an increasing demand for the application of non-contact temperature measurement technology in spacecraft thermal test.This paper takes the application of infrared temperature measuring equipment in vacuum and high-low temperature environment as the research object,designs the thermal protection scheme and device of the equipment,and simulates and analyses the thermal protection of infrared temperature measuring equipment based on node network method.Through physical test,the device can effectively realize the thermal protection of equipment in vacuum and high-low temperature environment,and ensure that the equipment is in the normal working temperature range and its temperature measurement algorithm model is not affected,the accuracy of temperature measurement is better than±2℃.It meets the requirements of equipment in space environment test.
