基于LabVIEW平台的数据采集系统中模拟量和脉冲量同步问题的探讨

The Exploration of Synchronous Problem of Analog Input and Counter Input Based on LabVIEW Platform

同步问题是为了解决船模实验中同步采集拖车速度和其它物理量(模拟信号)而提出的。本文讨论了在LabVIEW环境下所能考虑到的所有的解决方法,详细说明了这些方法的实现,就其利弊及实验中出现的问题和结果作了深入的分析,并对各种方法进行了比较。

The synchronous problem of analog input and counter input in the data acquisition system based upon the LabVIEW platform was to address the problem in shipping modules experiment of acquiring the towing car＇ s speed and the rest of analog signals synchronously. This paper took into account all the solutions which were discussed in the LabVIEW environment, giving a method to achieve this goal, and conducted an analysis of these methods＇ advantage and disadvantages and a comparison of various methods.
