摘要
根据近红外光谱仪(NIRS)的特点,利用C8051F120单片机提出一种数据采集系统的设计方案,实现了对数据的精确采集。本文扼要介绍了C8051F系列单片机的接口结构及工作原理,重点阐述了近红外光谱仪的系统结构,以及数据采集系统的硬件设计和软件流程,给出了电路原理图和软件流程图。
According to the characteristics of signals of NIRS, a data-acquisition system based on C8051F is presented. With this system, the NIRS can acquire the data precisely. This paper introduces the characteristics of the interfaces and principle of C8051F, focuses on the structure of the NIRS system, the hardware and software of the data-acquisition system designed by C8051F. The scheme and flow chart of the software would be given.
