基于LabVIEW的數(shù)據(jù)存取優(yōu)化設(shè)計

摘要 本文介紹了基于LabVIEW對大氣濃度進(jìn)行實時監(jiān)測，通過LabSQL將采集的信號等間距時間段自動存入數(shù)據(jù)庫（ACCESS）。LabSQL的開發(fā)是在LabVIEW 中利用Active X功能,通過調(diào)用Microsoft ADO控件,結(jié)合SQL語言,并通過ODBC接口函數(shù)庫驅(qū)動程序?qū)崿F(xiàn)對數(shù)據(jù)庫的訪問。采用虛擬儀器技術(shù)，開發(fā)研制基于LabVIEW的數(shù)據(jù)存取系統(tǒng)，可代替多個空氣質(zhì)量監(jiān)測儀器，使得多點空氣質(zhì)量監(jiān)測方便易行，并節(jié)約了測試成本。同時，其界面友好，操作自如，有著十分廣闊的應(yīng)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.
