基于LabVIEW的数据采集系统研究

针对在虚拟仪器的使用过程中需要利用数据采集卡对实验数据进行采集,而专用数据采集卡价格较贵这一现实问题,提出了一种基于LabVIEW的数据采集系统的设计方案,介绍了该系统的硬件组成及软件设计。该系统采用双51单片机控制技术,通过USB接口实现多种数据采集对象的在线实时传送或离线大容量数据存储等功能,达到了取代专用数据采集卡的目的。

Research of Data Acquisition System Based on LabVIEW

In view of problems that data acquisition card must be used to collect experimental data in use of virtual instrument and price of private data acquisition card is very high,the paper put forward a design scheme of data acquisition system based on LabVIEW and introduced the(system's) hardware configuration and software design.The system uses dual MCS51 control technology to achieve functions of on-line data acquisition or off-line mass data storage through USB interface,which can displace private data acquisition card.
