摘要
介绍研制的太阳跟踪和傅里叶变换红外(FT IR)光谱技术相结合的大气成分监测系统。该系统跟踪部分以ATm ega128芯片为控制核心,结合光学、电子学、GPS模块、PSD位置传感器以及机械部分完成对太阳运行的实时跟踪,利用FT IR光谱仪和计算机处理得到的光谱数据用于大气成分的监测。通过实验验证,FT IR大气成分监测系统运行稳定、可靠,跟踪精度在0.3°以内。
An atmospheric composition monitoring system, in which the sun-tracking and FTIR spectroscopy are combined, is introduced. The ATmega 128 chip is used as a controlling core of the tracking section of the system to realize real-time tracking of the sun in combination with the optics, electronics, GPS module, PSD position sensor and mechanical section. The spectral data gained by FTIR spectrometer and the computer is applied to the atmospheric composition monitoring. The system was verified by the experiments. The experiments show that the system is stable and reliable, and its tracking accuracy is within 0.3°.
