摘要
本文介绍了基于单片机AT89C52的光离子化检测仪构建。硬件系统利用AT89C52芯片实现了电压信号的数据采集与A/D转换、数码显示和数据串口发送,软件系统采用模块化设计,分为数据采集、数据存储和数据串口发送模块等。
In this paper, the construction of photoionization detect instrument based on AT89C52 chip is presented. In the hardware system, AT89C52 chip is used to realize the data acquiring and A/D conversion of voltage signal, digital display and the data sending of serial interface. The software system is based on the design of modularization, including the modules of data acquisition, data preserving and data transmission by serial interface.
