用VC++实现原子吸收光谱仪串行口实时数据采集和即时曲线显示

Realization of atomic absorption spectrometer's serial communication for data acquisition and real-time plotting with Visual C ++

在分析仪器的计算机系统改造过程中,仪器串行口通信编程是关键。本文详细介绍了在VC++6.0环境下用MSComm通信控件开发串行口(RS-232)的通信程序,实现了微机通过串行口对902型原子吸收光谱仪进行实时数据采集和实时曲线显示。程序代码详细,对其它分析仪器的计算机系统改造有重要的参考价值。

Serial communication is a commonly used communication in analytical instruments,and the program of serial communicationis important to remake the instrument computer systems.The paper introduces a design method and steps using Microsoft Communica-tion Control to develop the program of serial communication with VC++6.0,and realizes real-time data collection and real-time plot-ting between microcomputer and spectrometer.Several brief and useful programs are also given to solve the practical problems of highspeed and complex serial communication.
