摘要:

       设计了一种利用臭氧氧化法检测土壤有机质的信号采集系统,该系统采用ATmega16单片机作为嵌入式信号采集处理系统的核心芯片,光电转换模块则利用日本滨松光电倍增管来完成。系统通过RS-232串口与PC机通信,PC机软件实时接收嵌入式信号采集处理系统的采样数据。实验证明,系统运行可靠,达到了设计要求。

Abstract:

         We design a signal acquisition system for the detection of the content of soil organic matter, which is based on a single chip microcomputer (SCM). Its core chip is ATmega16 and optoelectronic conversion module is a HAMAMATSU made photomultiplier. It communicates with a PC through a RS-232 serial interface. Experiments show that the system is reliable and satisfies the design requirements.

Key words: ATmega16, ozone oxidation, soil organic matter, signal acquisition, measuing instruments
