基于LabVIEW的数据存取优化设计

摘要 本文介绍了基于LabVIEW对大气浓度进行实时监测，通过LabSQL将采集的信号等间距时间段自动存入数据库（ACCESS）。LabSQL的开发是在LabVIEW 中利用Active X功能,通过调用Microsoft ADO控件,结合SQL语言,并通过ODBC接口函数库驱动程序实现对数据库的访问。采用虚拟仪器技术，开发研制基于LabVIEW的数据存取系统，可代替多个空气质量监测仪器，使得多点空气质量监测方便易行，并节约了测试成本。同时，其界面友好，操作自如，有着十分广阔的应用前景。

LabVIEW-based data access optimization design

Abstract  This paper introduces the real-time monitoring of atmospheric concentrations based on LabVIEW,the signal will be collected by LabSQL equidistant time automatically and stored in the database(ACCESS). In LabVIEW, the development of LabSQL is used of Active X which calls the Microsoft  ADO control,and combines with SQL language,and achieve access to the database through ODBC driver interface function library. Virtual instrument is used to develop data access system,the system can replace multiple air quality monitoring equipment,make more convenient and easy to monitor concentration of air quality and save the cost of testing.At the same time,the system has friendly interface,ease for operator and has a very broad application prospects.
