摘要
在有关虚拟仪器及其编程语言LabVIEW的教科书中,对如何建立数据采集任务介绍了3种方式,即利用MAX软件、DAQ助手和DAQmx VI函数。但由于对这三者之间的逻辑关系介绍得不尽清楚、简明,致使学习者对这部分内容存疑较多,甚至概念模糊、不得要领。事实上,基于LabVIEW建立数据采集任务,本质上只有2种方式,即利用DAQ助手或利用DAQmx VI。本文试对基于LabVIEW实现数据采集的方式进行梳理和归纳,阐述MAX、DAQ助手、DAQmx VI之间的逻辑关系,着重分析DAQ助手和DAQmx VI函数的优缺点,进而给出使用建议。
In the current textbooks about LabVIEW,when talking about the creation of data acquisition task,three ways are presented：using MAX software,DAQ Assistant and DAQmx VI.Because the logical relationship between these three software was not clearly introduced,the programming ability and learning efficiency of students are greatly reduced.In this paper,the logical relationship between MAX,DAQ Assistant,and DAQmx VI was described,the advantages and disadvantages of DAQ Assistant and DAQmx VI was compared,and some use suggestions are proposed.
