基于单片机控制的人体健康监测系统设计

I摘要本系统设计的是基于单片机控制的人体健康监测系统，本系统需要检测人体的三个健康体征：心跳、体温、血压。由硬件和软件两部分组成。首先是心跳检测，利用压电传感器将检测到的心跳信号转换为电信号再通过集成运放转换成单片机可以接收的信号。其次是温度检测，利用一线口温度传感器DS18B20进行温度检测，由于该芯片采用单总线模式，在编程过程中严格按照该芯片的读写时序进行温度检测。再次是血压检测，利用压力传感器BP01将血压转换成为电信号，通过ADC0809模数转换器转化为数字信号通过单片机处理显示出来。另外还包括单片机电源电路、超限报警电路、复位电路以及键盘电路。本系统的研究于开发有利于人体健康检测的需要，对日常生活的改善有很多好处，具有很高的实用价值。关键词单片机8051；DS18B20；BP01；A/D转换毕业设计(论文)AbstractIIAbstractThissystemdesignisthehumanbodyhealthmonitorsystemwhichcontrolsbasedonthemonolithicintegratedcircuit,thissystemneedshealthilytoexaminethehumanbodythreehealthbodydrafts:Palpitation,bodytemperature,bloodpressure.Arecomposedbythehardwareandthesoftwaretwoparts.Firstisthepalpitationexamines,willexaminethepalpitationsignalusingthepiezoelectricpick-uptotransformintotheelectricalsignaltransportsagainthroughtheintegrationputstransformsthesignalwhichthemonolithicintegratedcircuitwillbeallowedtoreceive.Nextisthetemperatureexamination,usesmouthtemperaturesensorDS18B20tocarryonthetemperatureexamination,becausethischipusesthesinglemainlinepattern,strictlycarriesonthetemperatureexaminationintheprogrammingprocessaccordingtothischipread-writesuccession.Isthebloodpressureexaminationoncemore,transformsintousingpressuretransmitterBP01thebloodpressuretheelectricalsignal,transformsthroughtheADC0809modulusswitchforthedigitalsignaldemonstratesthroughmonolithicintegratedcircuitprocessing.Moreoveralsoincludesthemonolithicintegratedcircuitpowercircuit,ultralimitsthealarmcircuit,repositionstheelectriccircuitaswellasthekeyboardelectriccircuit.Thissystemresearchisadvantageoustothedevelopmenttothehumanbodyhealthexaminationneed,hasverymanyadvantagetothedailylifeimprovement,hastheveryhighpracticalvalueKeywordMonolithicintegratedcircuit8051;DS18B20;BP01;A/Dtransformation毕业(论文)目录III目录中文摘要及关键字.............................................................................................................-I-英文摘要及关键字............................................................................................................-II-绪论..................................................................................................................................-1-1.总体方案.....................................................................................................................-2-1．1方案论证及系统工作原理..............................................................................-2-1．2总体方案图.....................................................................................................-2-2硬件设计.......................................................................................................................-3-2．1主控芯片MCS—51介绍................................................................................-3-2．2ADC0809的介绍.............................................................................................-8-2．3心跳检测原理设计........................................................................................-10-2．4温度检测的原理及设计.................................................................................-11-2．5血压检测电路原理及设计............................................................................-15-2．6其他电路设计................................................................................................-17-2．7硬件总电路图...............................................................................................-17-3．软件设计..................................................................................................................-18-3．1主程序流程图................................................................................................-18-3．2子程序流程图...............................................................................................-19-3．2．1心跳检测流程...................................................................................-19-3．2．2温度检测流程图...............................................................................-20-3．2．3血压检测流程图...............................................................................-21-3．3主程序清单....................................................................................................-22-3．4子程序清单....................................................................................................-25-3．4．1心跳子程序：...................................................................................-25-3．4．2温度检测子程序：...........................................................................-27-3．4．3血压检测子程序：...........................................................................-31-结论................................................................................................................................-33-致谢............................................................................................................................-35-参考文献........................................................................................................................-36-附录一............................................................................................................................-37-附录二.................................
