摘要
介绍一种以单片机作为下位机采集数据,并经RS232串口传输到上位机——计算机的数据采集系统的实现方法。在VB开发环境下,运用VB提供的通信控件,实现PC机与89C51单片机之间的串行通信,并对采集的数据进行实时图形化显示、处理、存储等功能并给出硬件结构图和软件流程图。
This paper presents a data acquisition system consisting of SCM, RS232 serial ports and a computer. In VB development environment, with communication widget supplied by VB, to realize operation configuration and data communication between PC and 89C51 SCM, to display, process arid store data, and to present hardware structural chart and software flowchart.
