摘　　要：在工业生产过程中,常常需要对一些数据进行高精度低速采集。介绍一种基于Delphi 7.0的数据采集系统。该系统在自制数据采集卡的基础上,达到了高精度低速采集的要求;并利用SPcomm串口控件和TChart绘图控件,实现了计算机通过串口接收数据采集卡的A/D数据,且通过数据处理,绘制出了采集数据的实时曲线图。It usually needs to sample some data for high resolution and low speed in the industry process. This article introduces a data acquisition system based on Delphi 7. 0. This system uses a data acquisition card which is made by itself, realizes high resolution and low sampling speed. What＇s more, it realizes that PC has received sampling data form data acquisition card through serial port by SPcomm serial port component and it draws a real - time picture by TChart component for sampling data after data process.
