摘要
设计了一种便携式的光谱检测系统。该系统采用线阵CCD作为光电转换器件。它以基于ARM架构的S3C2410为核心,在其上移植了嵌入式Linux操作系统,开发了Linux下A/D转换驱动程序,并利用Qt/Embedded开发了人机界面。实际应用表明:该系统能够实现光信号的采集处理以及光谱图的绘制。人机界面友好、操作简单、功能较强、准确度高。
A design of portable spectrum detecting system was introduced. The system used linear CCD as photoelectric transducer. It used S3C2410 based on advance RISC machine architecture as core and the embedded Linux real time operating system was transplanted. The analog-to-digital conversion device driver was developed under Linux and human-computer interface was developed by using Qt/Embedded. The practical application shows that the system can realize optical signals acquisition and processing, and spectrum char drawing. It has friendly human-machine interface, easy operation, strong function and high accuracy.
