摘要
在太空环境中,卫星的公转会给自身带来较大的温差和温度交替频率,为了对卫星结构的温度场进行实时监控,采用准分布式光纤光栅测温系统。分析对比现有成熟技术,对光纤光栅种类、解调仪选型、卫星内布线方法和传感器封装技术等方面进行探究,通过一系列模拟试验,得出基于光纤光栅传感器的卫星温度场测量的较优方案,为后续工程提供指导性建议。
In the space environment, the satellite transfers itself to a large temperature difference and temperature al- ternating frequency. In order to realize the real-time monitoring of the satellite structure's temperature field, the quasi dis- tributed fiber grating temperature measuring system is adopted. The existing mature technology is analyzed and compared to explore the fiber grating type,the demodulation instrument selection, the intra satellite routing method andthe sensor package technology. Through a series of simulation experiments, based on the optical fiber grating sensor, the satellite opti'mum scheme is gotten to provide guidance for the follow-up project implementation to measure the temperature field.
