密级：学士学位论文THESISOFBACHELOR（年）题目：温度数据无线传输系统学院：系专业：班级：学号：学生姓名：指导教师：起讫日期：温度数据无线传输系统专业：学号：姓名：指导老师：摘要人们生产生活需要知道温度，工业生产需要知道温度控制温度。为了生产生活的需要，我们要有一套及时、方便、有效、快捷的传输温度量的系统。本系统主要有两个模块，一个温度采集发送模块和一个温度数据接收模块。在温度采集模块通过温度传感器DS18B20采集温度数据，这种传感器可将模拟的温度量转换成数字量通过IIC总线将数据传送到单片机，单片机采用LM3S1138芯片，这个芯片具有很快的处理速度，有单独的休眠模块，通过软件使其进入休眠非常省电。然后将温度数据送到无线发射模块，我采用的无线发射是工业通用的nRF905无线收发模块，将数据送到无线发射模块中，发射模块会自动将数据打包，最后将数据发送。数据接收模块中无线接收模块每隔650us扫描一次，当有同频率的信号过来时就开始接收数据包，将接收到的数据包解压，将数据送到单片机，然后单片机将数据送到上位机，上位机既可以处理数据。该设计可以使温度数据及时的监控，通过无线传输不用布线。并且可以方便的在上位机处理数据。关键词：DS18B20，LM3S1138，nRF905，温度采集，无线传输。TemperaturedatawirelesstransmissionsystemAbstractPeopleneedtoknowproductionandlifeoftemperature,theindustrialproductionneedtoknowthetemperatureandcontroltemperature.Inordertotheneedsofproductionandlife,wewanttohaveatimely,convenient,efficient,quicktransmissiontemperatureamountofsystem.Systemtherearetwomainmodules,atemperaturegatheringsendmoduleandatemperaturedatareceivingmodule.IntemperatureacquisitionmodulethroughthetemperaturesensorDS18B20collectiontemperaturedata,thesensorcanbesimulatedtemperatureisconvertedintodigitalquantitythroughtheIICtrunktosenddatatoasingle-chipmicrocomputer,thesinglechipmicrocomputerLM3S1138chip,thechiphasquicklyprocessingspeed,hasaseparatedormancymodule,throughthesoftwaremakeitintothedormancyveryprovinceelectricity.Thenwillthetemperaturedatasenttowirelesstransmittingmodule,IusewirelesslaunchisthenRF905industrialgeneralwirelesstransceivermodule,thedatasenttowirelesstransmittingmodules,launchmoduleautomaticallywilldatapacking,finallywillsenddata.Datareceivingmodulewirelessreceivingmodulesinevery650usscanningtime,whenthefrequencyofthesignalwithcamethroughtoreceivedatapackets,willreceivethepacketdecompression,datatothesinglechipmicrocomputer,andthenthedatasenttothesinglechipmicrocomputeruppermachine,PCcanprocessingdata.Thisdesigncanmakethetemperaturedatatimelymonitoring,throughthewirelesstransmissionneednotwiring.Andcanbeconvenientinuppermachineprocessingdata.KEY:DS18B20,LM3S1138,nRF905,Temperaturegathering,Wirelesstransmission目录摘要......................................................................................................................ⅠAbstract................................................................................................................Ⅱ•绪论.......................................................................................................1•课题的来源与研究意义....................................................................1•国内外研究现状及发展趋势............................................................1•本文主要研究内容............................................................................2•温度采集发射硬件及工作原理..............................................................32.1系统总体方案设计.............................................................................32.2温度采集的硬件电路及工作原理....................................................32.3温度采集电路....................................................................................32.4单片机选型........................................................................................62.5复位电路............................................................................................72.6电源电路............................................................................................82.7无线发射电路....................................................................................8第三章温度数据接收硬件及工作原理...........................................................133.1温度数据接收的硬件电路及工作原理...........................................133.2单片机选型......................................................................................133.3电源电路及串口通信......................................................................133.4无线接收电路..................................................................................14第四章软件设计...............................................................................................154.1温度采集发射模块软件设计...........................................................154.1.1主程序...................................................................................154.1.2温度采集模块程序...............................................................164.1.3无线发射模块程序...............................................................204.2温度数据接收模块软件设计...........................................................214.2.1主程序...................................................................................214.2.2数据接收模块程序...............................................................22结论.....................................................................................................................26参考文献.............................................................................................................27致谢.....................................................................................................................28附录：1.温度采集发射模块电气原理图2.温度数据接收模块电气原理图3.温度采集发射模块PCB图4.温度数据接收模块PCB图5.温度采集发射模块程序清单6.温度数据接收模块程序清单•绪论•课题的来源及研究意义温度数据无线传输系统，主要用于对温度的自动采集和温度数据的自动无线传输。对于现在社会，气象的发展以及人们对气象服务的需求日益增多[1],而以前用的各种型号的温度表，人工根据温度表刻度读数的采集方式已经远远不能
