| 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. |
