本文介绍了计算机控制实验系统的开发及研究。在该系统硬件构成中,采用加热炉作 为控制对象,试验仪器,线路板,数据采集卡及PC 机,实现了对计算机控制技术的实践教学系统的硬件环境配置。实验系统软件采用虚拟仪器 (Virtual Instruments, VI)技术,开 发环境是美国国家仪器公司 (NationalInstruments,NI)推出的虚拟仪器应用软件开发平台 LabVIEW7.0。系统投入使用后取得良好的教学效果。 关键词: 虚拟仪器 PCL -818 LabVIEW Abstract:In this paper the experiment System for The course of computer control are introduced. The experiment system is made up of control object, test instrument, connection board, date gather card and computer. The experiment system software based on LabVIEW7.0 and PCL -818L is devoleped. The new modularization system based on the platform of virtual instrument is established. A good teaching effect has been brought after the experiment system for the course of computer control had been applied. Keywords: virtual instrument;PCL -818 ; LabVIEW
