摘要
Abstract
A gas detection system based on FPGA is proposed,which realizes the miniaturization and digitalization of TDLAS gas measurement system. FPGA have good performance on parallel computing, easy to realize DDS and quadrature digital phase-locked which can be used to calculate the high frequency signal and the extraction of har-monic signal in the process of TDLAS measurement. The laser, the temperature control module, the current drive module,the signal generator,the photoelectric detector,the band-pass filter and the ADC sampling are integrated on the same printed circuit board to realize the miniaturization and integration of the system. Finally,the stability of the system is verified by monitoring the oxygen concentration in the air for a long time.关键词
