摘要
本文介绍了一种基于数字信号处理器DSP的智能光谱仪电路系统的设计与实现方案。整个系统通过DSP驱动CCD传感器采集信号,并由DSP完成模数转换以及各种变换运算,最后由DSP控制液晶显示模块输出光谱曲线。此外,该系统还可以实现与计算机的串口通信。由于在系统中采用了高性能的数字信号处理器,使得系统的结构简化,可靠性高,可实时与智能控制,扩展性强,成本低。
Electronic design of intelligent spectrometer is introduced. In this system, DSP drives CCD to collect signals, converts analog signals to digital signals, completes fast Fourier transform, and controls LCM to display spectrogram. Due to DSP, it has the features of simplified configuration, high reliability, real-time and intelligent control, excellent expansibility and low cost.
