【摘要】 本文对虚拟示波器的结构进行了分析,设计出基于AVR单片机现场数据采集系统与MATLAB应用软件的虚拟示波器。文中详细给出了数据采集系统的设计,基于MATLAB仪器控制工具箱的数据通信软件的设计,以及MATLAB下波形显示程序的设计。所设计的虚拟示波器在一阶惯性电路上进行实验测试,测试结果表明该设计正确、可行。更多还原

【Abstract】 The paper analyses the structure of the Virtual-Oscillograph,and designs one based on AVR-MCU data -acquisition system and MATLAB applications.This paper describes detailedly the designs of the data-acquisition system,the communicati on software based on MATLAB’s Instrument Control Toolbox,and the waveform-display software under MATLAB. This virtual-oscillograph is experimentized with a first-order circuit,and the result indicates that this design is right and feasible.更多还原
