摘要随着工农业生产对温湿度的要求越来越高，准确测量温度变得至关重要。本文设计主要是针对恶劣环境下的工业现场以及高科技大范围的农业现场，布线困难，浪费资源，占用空间，可操作性差等问题做出的一个解决方案。该方案主要是利用热电偶采集外界的温度，利用无线传输实现在上位机显示采集到的温度，并对数据进行相应的对比和处理。本文主要利用两路热电偶采集温度的模拟量，并且利用热电偶串行模数转换器实现信号放大、冷端补偿和A/D转换，再由单片机进行处理，并通过无线传输模块将测量的数值传输给PC机，在PC机上实现数据的对比，从而可以对工业现场和农业现场的环境温度进行实时监测，并且利用该设计还可以实现对热电偶测量准确度的现场检测。本设计结构简单，但应用范围广泛，使用方便而且节约资源，同时可以进行远距离的监控。关键词：温度数据采集，无线传输，热电偶，单片机，PC机AbstractWiththemoreandmorerequestofindustryandagricultureproductioninthetemperature,itbecomeveryimportanttosurveythetemperatureaccurately.Thisarticleisdesignedforharshenvironmentsandhigh-techindustriesatthesceneoflarge-scaleagricultureatthescene,wiringproblems,wasteofresources,space,andmakeoperationalapoorsolution.Thisdesignismainlytousethethermocoupletogathertemperature,andthenusethewirelesstransmissiontorevealthegatheredtemperatureonthepositionmachine,andcomparisonofdataandprocessingthecorresponding.ThisdesignmainlyusestwothermocoupletogathertheanalogquantityofthetemperatureandusesthethermocoupleserialADCtoachievesignalamplification,coldjunctioncompensationandtheA/Dconversion,andthenthedigitalquantitywillbeabletobedistinguishedbythemicrochipandthentransmittedthroughthewirelesstransmissionmoduletothePC,andtoachievethecompareofdata,thenthetemperatureofthesceneofindustrialandagriculturalcanbemonitoredinanytime,andthroughthisdesignwecandetecttheaccuracyofthermocoupleatthesceneofmeasurements.Thissystemisofsimplestructure,butinextensiveapplicationrange,easybeingused.Moreover,itsavesresourcesandalso,thelongrangemonitormaybecarriedonatthesametime.Keywords:temperaturedataacquisition,wirelesstransmission,thermocouple,single-chip,PC目录摘要............................................................IAbstract...........................................................II目录..........................................................III第一章引言.....................................................11.1课题的背景和意义........................................................................................11.2无线温度采集原理........................................................................................21.3无线温度采集的发展状况..............................................................................41.4无线温度采集系统的研究内容......................................................................6第二章总体方案设计..............................................72.1任务要求..........................................................................................................72.2总体方案的论证..............................................................................................72.3总体方案的选择............................................................................................10第三章单元电路的设计...........................................123.1温度传感器信号调理电路............................................................................123.1.1热电偶...............................................123.1.2温度数据采集部分的放大电路...
