摘要
在LabVIEW开发环境下,为实时显示数据采集结果,通过结合虚拟仪器的概念,采用IVI驱动程序NI Scope和队列同步控制技术快速搭建实时数据采集系统。结果表明该系统可实现对模拟输入信号的实时采集和数据显示及可控制存储等功能,效果较好。特别是使用图形化编程语言,简化代码,操作方便,人机界面友好,可扩展性强。
In order to display the result of real- time data acquisition,combining to the idea of virtual instrument by using the virtual instrument of the development software LabVIEW, the real - time data acquisition system can be built quickly by using IVI device driver NI Scope and the queue for synchronizing control. The result indicates that the system can preferably realize and display the real - time data acquisition from analog input signal, data memory and so on. Especially by using the graphics programming language,the system can simplify codes, more convenient to operate with friendly interface and strong scalability.
