摘要
研制了一台应用于自动控制实验教学的虚拟仪器 ,其具体实现是以NI公司PCI 60 2 4E为数据采集卡 (DAQ卡 ) ,以LabVIEW为开发软件平台 ,编写了信号发生程序、信号采集程序和取代电子模拟仿真仪的传递函数仿真程序 ,从而实现了该全数字自动控制实验仪器所要求的各项功能。该仪器将信号生成、信号记录功能集成在一块DAQ卡上 ,特别是用传递函数仿真器取代了电路系统。
In order to develop a more compositive and flexible virtual instrument used in autocontrol test, PCI-6024E and LabVIEW of National Instruments Corporation are used as basic tools in the project. Several key programmes which are needed in the virtual instrument, such as waveform regenerator, data acquisition code, and transfer function emulator used to replace hardware emulator, have been designed successfully. This instrument integrates waveform regeneration with signal recording on a DAQ card, especially replaces circuit system with a transfer function emulator.
