Data Acquisition System for NIR Spectrometer Based on DSP

摘要：

In order to realize the integration of measurement, scan control and analysis of spectrum in the portable Near-infrared spectrometer, the data acquisition system based on DSP TMS320F2812 has been developed. The components of system include the analog-todigital conversion module, the grating scan driving module, the LCD display module, the external storage module and the keyboard control module. The software of system was built on Code Composer Studio with C program. The parameters of the system can be set and the commands can be sent uesing the keyboard. Then the stepper motor will be controlled to drive the grating to scan. At the same time, the analog-todigital conversion module acquires the real-time spectrum data. And a low pass digital filter has been designed to reduce the noise of the data. The data will be shown as a spectrogram on LCD and saved in the NAND Flash.
