摘    要:阐述了开放式虚拟仪器平台LabVIEW的特点,介绍了PCI总线技术。利用图形化编程语言LabVIEW的虚拟仪器和动态特性,在计算机上构成用户界面动态显示和交互,使用LabVIEW动态链接库,调用板卡函数开发出了一个由计算机控制的FIFO半满式32路数字量采集系统,并且进行了软件可行性的测试。数据采集卡配合虚拟仪器中的LabVIEW编程,就能完成数据采集过程。实验证明,采用这种方法省去了复杂的语言编程,缩短了软件的开发时间,简化了开发过程,同时也增加了应用的灵活性。

关 键 词:LabVIEW  PCI总线  数字量采集

Abstract:The features of LabVIEW are discussed,which is an open virtual instrument platform.The PCI bus technology is introduced.Using the dynamic characteristics and virtual instrument of the graphical programming language LabVIEW,a user interface is constituted to complete dynamic display and interaction.Using the dynamic link library and the function of DAQ,an half-full type 32-channel digital acquisition system is developed,which is controlled by computer.Then the feasibility of the software is tested.DAQ combined with LabVIEW program can realize the data collection process.The experiment results show that this approach can avoid the complex language programming,reduce the time of software development,simplify the development process and also increase the flexibility of the application.
Keywords:LabVIEW  PCI bus  digital acquisition
