摘要:

主要针对星载多路短波红外探测器的温度要求设计了高精度在轨温度控制系统。首先,在对工作温度控制需求进行分析的基础上,提出了该系统短波红外探测器的温度高稳定性要求;其次设计了高稳定性温度采集电路、低噪声热控驱动电路,并且在FPGA芯片上基于开关控制算法,产生了脉宽调制信号;然后利用该脉宽调制信号控制热电制冷器的驱动电流,实现了在资源有限的条件下,温度控制高稳定度的要求。最终性能测试的结果表明,温控的精度可以达到±0.1°的高稳定度要求,满足该多路短波红外探测系统星载工作温度要求。

Abstract:

An orbit temperature control system with high precision and stability is designed, which is aimed to satisfy the temperature requirements of satellite-borne multi-channel shortwave infrared detectors. First of all, according to the demand of operating temperature, the precision requirement of the shortwave infrared detector is presented. Then, the circuit,which acquires temperature with high stability as well as control thermal with low noise, is designed. Meanwhile, the pulse width modulation signal, established by FPGA based on the switch control algorithm, is used to control current of the thermoelectric refrigerator. The requirement of high stability temperature control with limited resources has been realized. The final test results show that the precision of the control system can reach ±0.1°, and meets the accuracy stability requirement of operating temperature.

Key words: polarized remote sensing, the satellite-borne, the shortwave infrared detector, the high stability refrigeration
