【摘要】 虚拟仪器的迅速发展,使得计算机控制的模块化仪器系统得到了广泛的认同与应用。本文建立了LabWindows/CVI和MATLAB的接口,实现了两者的混合编程,在此基础上设计了一个实用的信号采集、分析与处理系统,通过软、硬件技术结合,实现了对实际模拟信号的采集、分析与处理。为了节约系统开发时间和开发难度,在系统开发过程中使用了模块化的思想。更多还原

【Abstract】 The quickly development of Virtual Instrument makes the modular instrument,which is on computer control ,is accepted and applied widely.The meet between the LabWindows/CVI and MATLAB is build,so the mix-program betweenthe two software is realized,on this basis a data acquisition system and frequency-field signal processing system is presented.Through the technical combination of hardware and software,the signal acquisition and processing of various kinds of param-eters from multiple analog data are realized.In order to save the time of exploring the system and reduce the difficulties,themodular programming technology is used.更多还原
