摘要	大气主要温室气体检测仪采用HgCdTe探测器实现CO2温室气体干涉光谱数据探测,HgCdTe探测器工作温度对探测器性能具有重要影响。针对HgCdTe探测器恒定低温下工作的需求,设计了温度采集电路与温控功率驱动电路,并以Actel公司反熔丝工艺FPGA作为主控单元,结合PID算法,完成了星载HgCdTe探测器温控系统,实现了探测器在轨温度控制。实验及应用结果表明,控温精度优于±0.5℃,控温稳定性优于±0.1℃/s,满足HgCdTe探测器在轨工作温度要求。
其他摘要	HgCdTe detector was used to detect the interference spectra of CO2 greenhouse gases on spaceborne greenhouse gas detection equipment. The performance of HgCdTe detector is significantly affected by operating temperature,and the detector needs to work at a constant low temperature. According to the operating temperature requirement, a temperature control system for spaceborne HgCdTe detector was designed. The system is mainly composed of temperature acquisition circuit, power-driven circuit and a main control unit based on FPGA. PID algorithm was adopted to realize precise temperature control. The experiment and application results show that the temperature control precision is better than ±0.5℃, and the temperature stability is better than ±0.1℃/s,which satisfies the on-orbit working temperature requirement of HgCdTe detector.
