基于LabVIEW的数据采集系统的设计

Design of data acquisition system on LabVIEW

针对文本编程语言复杂、开发周期长的缺点,结合数据采集系统需要,在LabVIEW软件平台下开发了数据采集控制系统.运用队列缓存技术实现多线程间的数据同步,避免数据丢失,并且使数据采集分析与显示线程之间协调运行,遵循模块化的方法设计软件界面,实现了电路编程、采样读数等功能.结果表明,该软件运行可靠、操作简便、人机界面友好.

Combined with the needs of the system for data acquisition and aimed at the complex text programming language and long time of developing, the data acquisition and control software were designed by LabVIEW2010. Applying the queue cache technology to realize data synchronization between threads, to avoid the data loss and data collection and coordination between threads running; follows a modular approach software interface design and completes the circuit programming, sampling readings, etc. The results showed that the software should be reliable running, simple operation, and friendly man-machine interface.
