    The invention discloses a spacecraft thermal test reference point thermal response test system. The system comprises a control unit, a first information exchange unit, a data acquisition unit and a branching unit, the control unit is used as a main control unit, the selection, heating and temperature collection of reference points are controlled in a communication connection mode, and the first information exchange unit is used as an information exchange medium between the control unit and the data collection unit; the connection between a field acquisition device and each reference point in a vacuum container is established through the branching unit, the branching unit receives a to-be-measured reference point selection electric signal, selects one to-be-measured reference point and performs heating operation, and then the data acquisition module receives a temperature data acquisition electric signal and acquires temperature data. Acquired temperature data is converted by the first information exchange unit and then is transmitted to the control unit for storage; the correctness of the matching relation between the reference point platinum resistor and the thermocouple compensation end is effectively verified, and the vacuum thermal test of the spacecraft is ensured to be smoothly carried out.

    本申请公开了一种航天器热试验参考点热响应测试系统。包括：控制单元、第一信息交换单元、数据采集单元以及分线单元；本申请利用控制单元作为主要控制单元，通过通信连接方式控制参考点的选择、加热、温度采集，利用第一信息交换单元作为控制单元与数据采集单元之间的信息交换介质；通过分线单元建立现场采集器件与真空容器中各参考点的连接，其接收待测参考点选择电信号，选择一个待测参考点，进行加热操作，再利用数据采集模块接收温度数据采集电信号，对温度数据进行采集，采集到的温度数据经第一信息交换单元转换后传输至控制单元进行保存；实现有效验证参考点铂电阻与热电偶补偿端匹配关系的正确性，保障航天器真空热试验顺利进行的目的。
