摘要
为解决传统的硬件实验受实验时间、场地和学校投入等因素限制较大的难题,利用高性能的模块化硬件结合灵活高效的软件,将LabVIEW应用于机械工程测试的教学中以满足各种测试和控制的需要。以凌华USB数据采集卡为硬件平台,利用LabVIEW 8.6编制软件搭建信号采集与分析系统。该系统包含3个模块:信号的采集、数据存储和调用以及信号的时频域分析模块。最后,利用信号发生器作为信号源进行数据采集试验,验证了该数据采集系统的性能,证明了该系统的可行性和实用性。
The Time , area and large cost in experimental teaching must be devoted to purchasing traditional instrument seriously restrict .In order to solve this problem , it applies LabVIEW in teaching activity and combined the hardware experiment with virtual experiment .For example ,it realizes the time frequency analysis of signal in LabVIEW.Instrument panel and program chart of LabVIEW that illustrates the characteristic of virtual experiment teaching are listed , which show LabVIEW can provide a new manner for experiment teaching .
