基于RS-232的通用自动测试系统设计与应用

An Universal Measurement System Design and Application Based on RS-232

本通用自动测试系统利用数字万用表的自带 RS-232接口,以可视化 C 语言作为编程语言,实现各类模拟量的采集、存盘,并以文本和图形两种方式实时显示。该系统还可根据用户要求进行极大值、极小值、均值、方差等简单统计计算。在多种机型上的使用结果表明,该系统可以在多种 Windows 操作系统上稳定工作。

RS-232 port was employed to communicate between multimeter and computer in the universial measurement system.The system could gather,save and display analog signal.Also,it could carry out basic statistic calculations ac- cording to the user's selection.The interface and program were written by viewable C language.Experiments suggest that the system can work stably on any Windows-O peration-System.
