摘要随着电子测试技术的不断发展,测试技术正向自动化,智能化,数字化和网络化的方向发展。其中数字滤波器作为测试技术的重要工具而被广泛的使用与各个领域。本课题是用Labview来实现温度检测系统的设计以及应用首先,本论文介绍Labview相关知识,利用虚拟仪器的开发平台——Labview开发的软件系统,主要包括五个模块:数据采集,显示记录,数据回放,数据处理和数据分析。VI是计算机技术和传统的仪器技术相结合的产物,是仪器发展的一个重要方向,Labview是一个基于图形虚拟仪器的软件开发工具,主要用于自动测试、过程控制、仪器设计和数据分析等领域,其基本思想是在仪器设计或测试系统中尽可能用软件代替硬件,即“软件就是仪器”,他是在通用计算机平台上,根据用户需求来定义和设计仪器的测试功能,其实质是充分利用计算机的最新技术来实现和扩展传统仪器的功能。本文重点介绍了虚拟仪器的界面Labview的应用,并设计一个基于虚拟仪器的数字和控制系统,阐述了系统开发过程中数据的采集和软硬件的设计关键字:Labview温度测量数据采集AbstractAlongwiththeelectronictesttechnology'sunceasingdevelopment,thetesttechnologyforwardautomation,theintellectualization,digitizedandthenetworkdirectiondevelops.Andthedigitalfiltertakethetesttechnologytheimportanttoolbythewidespreaduseandeachdomain.Thistopicisrealizesthetemperatureexaminationsystem'sdesignaswellastheapplicationwithLabviewfirst,thepresentpaperintroducedthattheLabviewrelatedknowledge,theusehypothesizedinstrument'sdevelopmentplatform--Labviewdevelopment'ssoftwaresystem,mainlyincludesfivemodules:Thedataacquisition,demonstratestherecord,playbacking,thedataprocessingandthedataanalysis.VIistheproductwhichthecomputertechnologyandthetraditionalinstrumenttechnologyunifies,isanimportantdirectionwhichtheinstrumentdevelops,Labviewisonebasedonthegraphhypothesizedinstrument'ssoftwaredevelopmenttool,mainlyusesindomainsandsoontestautomation,processcontrol,instrumentaldesignanddataanalysis,itsbasicphilosophyisusesthesoftwareintheinstrumentaldesignorthetestsystemtoreplacethehardwareasfaraspossible,namely“thesoftwareistheinstrument”,heisinthegeneral-purposecalculatorplatform,definesanddesignsinstrument'stestfunctionaccordingtotheuser'sneeds,itsessenceisrealizesfullyusingcomputer'snewesttechnologywiththeexpansiontraditioninstrument'sfunction.Thisarticleintroducedwithemphasisthehypothesizedinstrument'scontactsurfaceLabviewapplication,anddesignsonebasedonthehypothesizedinstrument'sdigitandthecontrolsystem,elaboratedinthesystemperformancehistorydatagatheringandsoftwareandhardware'sdesignKeyword:LabVIEWTemperaturesurveyDataacquisition目录摘要……………………………………………………………………………………ⅠAbstract………………………………………………………………………………Ⅱ第一章绪论1.1课题背景………………………………………………………………………11.1.1背景简介…………………………………………………………………21.1.2引言………………………………………………………………………2第二章虚拟仪器简介2.1虚拟仪器特点……………………………………………………………………32.2虚拟仪器构成……………………………………………………………………4.3Labview8.5的安装及应用……………………………………………………5第三章系统硬件设计3.1系统设计流程模块………………………………………………………………63.2硬件电路设计……………………………………………………………………73.2.1硬件电路基本组成………………………………………………………93.2.2硬件电路基本功能描述…………………………………………………03.2.3硬件电路模块功能分析………………………………...
