摘　　要：为了提高电学演示实验的可见度和精确度,提出一种能实时展示实验操作过程、同步显示实验原理和实时采集实验数据的综合实验平台。利用简易的音频插孔,采用AT 89C 52单片机作为控制核心分析处理各种反馈信号,通过串口扫描枪识别元件,编写L abV IEW程序显示实验原理图。同时,通过高速摄像头实时展示实验操作过程,用智能万用表进行数据采集。实践表明,此演示平台操作简单、效果直观,具有实时、同步、量化三个重要特征,解决了电学演示实验过程难以远距离观察,分析处理结果非实时的问题,有力地支持了信息技术与物理教学的全面整合。In order to improve the visibility and accuracy of the electrical demonstration experiment, an integrated experiment platform which includes real-time display of experimental operation, synchronous display experimental principles and real-time collection of experimental data is presented. The program to show the experimental schematic with LabVIEW is written by the use of simple audio jacks and adopting AT89C52 singlechip as the center to analyze all kinds of feedback signals and the exploitation of serial Port scan-gun to recognize components meanwhile the experimental procedures are shown by the use of high-speed camera and a smart multimeter to collect the experimental data. The experiment shows that such a platform is characterized by real-time, synchronization and quantization and easy to operate and its effect is visual. The problem that electrical demonstration experiments are immune to remote observation and the processing of the results of such experiments are solved by using the platform, which results in a comprehensive integration of information technology and physics teaching.
