多超声波传感器的距离测量系统设计.docx

****************论文摘要摘要本文详细介绍了一种基于AT89C51单片机的脉冲反射式双传感器超声波测距系统设计，具体内容为测距单元硬件设计和单片机应用程序设计；该系统是以空气中超声波的传播速度为确定条件，利用发射超声波与反射回波的时间差来测量待测距离。本超声波测距系统设计基于Polaroid6500系列的超声波传感器及其驱动模块两套，设计以AT89C51单片机为核心的超声波测距电路，能实现多模式距离测量与温度补偿以及距离结果显示，并且能够以串行通信方式将处理后的测距数据信号传送到PC机，并从PC机接受控制信号。本系统安装使用方便，价格便宜，并可与遥测遥控系统配合使用，有较广阔的应用前景。关键词:超声波，超声波传感器，超声波测距系统，AT89C51单片机，温度补偿。ABSTRACTThethesisintroducesakindofsingle-pulse-reflectiondouble--ultrasonicsensorsdistancemeasurementsystemdesignindetailbasedontheAT89C51SCM.Thespecificcontentsarethedesignsofhardware’sunitandapplicationoftheSCM;Thissystemcouldmeasurecertaindistancewiththetimebetweentransmittedwaveandreflectedwaveonconditioninwhichthespeedoftransmittingwaveisfixedinroom。TheultrasonicdistancemeasuringsystemisbasedonthePolaroid6500seriesofultrasonicsensorsandtwosetsofdrivemodule,thedesignhasusedtakingtheAT89C51SCMasthecoreofultrasonicrangingcircuit,toachievemulti-modedistancemeasurementandtemperaturecompensation,theresultsdisplayedbyLED.AndsenttherangingdatasignalstothePCbythewayofSerialcommunicationafterthesignalsbeendealtwith,acceptcontrollingsignalsfromthePC.Thissystemiseasytobeinstalledandapplied，lowinPriceandcapableofbeingusedincombinationwiththesystemsoftelemeteringandtelecontrolling，andithasextensiveapplicationprospects.KeyWords:Ultrasonicwave,Ultrasonicsensor，Ultrasonicdistance-measurementsystem，TheAT89C51SCM，Temperaturecompensation.****************论文目录目录TOC\o"1-2"\p""\h\z\uHYPERLINK\l"_Toc201293993"第1章绪论………………………………………………………………PAGEREF_Toc201293993\h1HYPERLINK\l"_Toc201293994"1.1课题的提出…………………………………………………………PAGEREF_Toc201293994\h
