摘　　要：为辅助《检测技术与仪表》课程综合实验教学、改善实验教学质量,以单片机数据采集系统为例,提出了基于LabVIEW和Proteus的虚拟数据采集系统设计方法。利用Proteus中的AT89C51单片机作为下位机,实现数据采集、数据显示及向上位机传输数据功能。以LabVIEW软件为平台构建上位机系统,实时采集下位机数据,对采集的数据进行保存和分析处理,按需要回放存储数据。利用Virtual Serial Port Driver 6.0虚拟的一对串口实现上位机与下位机之间的通信。实验结果表明,设计的虚拟数据采集系统与实际系统实验结果一致。In order to provide an auxiliary teaching method for comprehensive experimental teaching of ＂Measuring Tech- nology and Instruments＂ course and greatly improve experiment teaching quality, a virtual data acquisition system based on Lab- VIEW and Proteus is presented. AT89C51 in Proteus is used as the slave computer to achieve the functions of data acquisition, data display and data transmission to the host computer. LabVIEW was employed to construct the master system to acquire realtime data from the slave computer, to save and process these data, and to playback them if necessary. The master system com- municated with the slave computer by a pair of virtual serial ports constructed by Virtual Serial Port Driver 6.0. Simulation resuits show the virtual data acquisition system has the same operation characteristic as the real hardware system.
