电子产品设计题目智能体温计姓名xxx学号xxx专业班级xxx所在学院信电分院指导教师（职称）杨锆二○一六年六月十九日摘要1电子产品设计——智能体温计摘要智能体温计采用AT89S52作为核心器件实现对系统的自动控制，采用双单片机串行处理结构。外界温度经AD590集成温度传感器采集，温度变化转换为线性电压信号，再经由OP07构成高精度低温漂的放大电路处理后，作为ADC0809的模拟输入信号，由ADC0809完成A／D转换，得到8位的数字信号送入单片机1（AT89S52）。单片机1将采集到温度值在LED数码管上显示出来，也通过串口通信将温度信号传到单片2（AT89S52）。此外温度预制，报警电路模块功能也由单片机1完成。单片机2完成温度值的语音播放功能。通过系统的设计与实现说明本设计方案切实可以，能够完成题目所要求的基本功能部分，并留有相应的接口，为完成扩展功能打下基础。关键字：单片机AD590ADC0809ISD2560Abstract2Electronicproductdesign——ElectronicthermometerAbstractIntelligenttemperaturemeteradoptsAT89S52asthecoredevicetorealizetheautomaticcontrolofthesystem,usingtheserialprocessingstructure.OutsidetemperaturebyintegratedtemperaturesensorAD590acquisition,temperatureconversionintothelinearvoltagesignal,andthenthroughtheOP07constitutehighprecisionandlowtemperaturedriftofamplificationcircuits,asADC0809analoginputsignal,bytheADC0809completea/Dconversionandget8bitdigitalsignalintothemicrocontroller1(AT89S52).SCM1willbecollectedtothetemperaturevalueintheLEDdigitaltubedisplay,butalsothroughtheserialcommunicationtothetemperaturesignaltothemonolithic2(AT89S52).Inadditiontothetemperature,thealarmcircuitmodulefunctioniscompletedbytheMCU1.SCM2tocompletethetemperaturevalueofthevoiceplayer.Throughthedesignandimplementationofthesystem,thisdesigncanberealized,cancompletethebasicfunctionalrequirementsofthetitle,andleavethecorrespondinginterface,forthecompletionoftheextensionfunctiontolaythefoundation.Keyword:singlechipmicrocomputerADC0809ISD2560AD590浙江大学城市学院毕业论文目录3目录摘要.....................................................................................................................................1第1章绪论....................................................................................................................11.1背景....................................................................................................................11.2设计目的............................................................................................................1第2章原理分析............................................................................................................22.1设计总原理........................................................................................................22.1.1温度传感器的选择.....................................................................................22.1.2A／D转换器的选择..................................................................................32.1.3语音提示模块.............................................................................................32.2原理分析............................................................................................................32.3系统电路原理图................................................................................................4第3章主要电路设计与参数计算................................................................................53.1电源电路模块....................................................................................................53.2温度检测、放大模块........................................................................................63.2.1换成DS18B20温度模块怎么改...............................................................63.2.2AD590简介................................................................................................63.2.3图5温度检测、放大电路原理.................................................................83.3A/D转换模块....................................................................................................83.4温度设制、显示及报警电路模块....................................................................93.5串行通信模块..................................................................................................103.6语音播放模块...................................................................................................113.6.1录音、放音简介........................................................................................113.6.2ISD2560简介............................................................................................113.6.3芯片工作原理...........................................................................................133.6.4硬件电路设计...........................................................................................143.6.5本方法的特点...........................................................................................14第4章系统软件设计..................................................................................................154.1系统程序流程图..............................................................................................15第5章系统测试..........................................................................................................165.1硬件测试..........................................................................................................165.1.1单元模块的测试.......................................................................................16浙江大学城市学院毕业论文目录45.1.2系统整体测试...........................................................................................175.1.3软件测试..........................................................................
