毕业设计基于LabVIEW的电子秤的设计研究摘要随着科学技术的进步，对测量技术的要求越来越高。电子测量技术在各个领域得到了越来越广泛的应用。传统的电子测量仪器由于其功能单一，体积庞大，己经很难满足实际测量工作中多样性、多功能的需要。以虚拟仪器为代表的新型测量仪器改变了传统仪器的思想，它们充分利用计算机强大的软硬件功能，把计算机技术和测量技术紧密结合起来，是融合了电子测量、计算机和网络技术的新型测量技术。特别是基于计算机平台的各种测量仪器由于成本低、使用方便等优点得到了更广泛的应用。本设计是结合传感器技术、数据采集技术和虚拟仪器技术开发设计了一种基于LabVIEW的电子秤，该系统采用普通PC机为主机,利用图形化可视测试软件LabVIEW为软件开发平台,将被测重量转换处理进行数据采集，实时进行处理、显示。关键词：电子秤；虚拟仪器；LabVIEWDesignoftheintelligentelectronicsteelyardbasedonLabVIEWAbstractWiththedevelopmentofscienceandtechnology,therequirementonmeasurementtechnologyisgettingmoreandmoreimportant.Theapplicationofelectronicmeasurementtechnologyhasextendedtomorefieldsthanbefore.Duetolimitedfunctionsandbigsize,traditionalelectronicmeasuringequipmentsarenolongersuitabletocommonpurposes.Therapiddevelopmentofintegratedcircuitandcomputertechnologygivesbirthtoanewkindofinstrument,VirtualInstrument(VI).Asaresult,thetestingcostincreasesbyawidemargin.Inrecentlyyears,anewmeasuretechnologythatcombinesthetechnologyofelectron,technologyofcomputer,technologyofnetwork,isdevelopedandthisnewtechnologyisnamedVI.Especiallyvariousmeasuringinstrumentsbasedoncomputer,theyaremorewidelyusedbecauseoftheirexcellencesuchas:lowercost,easilyused,etc.Thedesignofsensortechnology,dataacquisitiontechnologyandinstrumenttechnologydevelopmentanddesignaLabVIEW-basedelectronicsteelyard,thesystemusedforordinaryPC-host,theuseofgraphicvisualtestsoftwareforLabVIEWsoftwaredevelopmentplatform,theweightwillbetestedConversionprocessingofdataacquisition,real-timeprocessingthat.Keyword:Electronicssteelyard;Virtualinstrument;LabVIEW目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc200951558"摘要PAGEREF_Toc200951558\hIHYPERLINK\l"_Toc200951559"AbstractPAGEREF_Toc200951559\hIIHYPERLINK\l"_Toc200951560"第一章引言PAGEREF_Toc200951560\h3HYPERLINK\l"_Toc200951561"1.1研究背景PAGEREF_Toc200951561\h3HYPERLINK\l"_Toc200951562"1.1.1称重技术和衡器的发展PAGEREF_Toc200951562\h错误！未定义书签。HYPERLINK\l"_Toc200951563"1.1.2电子秤的发展状况PAGEREF_Toc200951563\h
