I智能运动手环设计摘要当今社会随着人类的生活水平提高，大家对各自的健康问题有了更大的关心，只有一个好的身体才能体会生活，但是怎么才能让大众更好的去了解自己的身心健康呢？电子信息技术和医学刚好都在同步发展，两者合二为一刚好可以解决人们对于健康问题的困扰，因此人们对于高精密便携式医疗监控仪器的需求更大了。人体监控指标普遍通过心率计步两大指标，由于这个原因，本次毕设根据时代发展的需求设计一款基于单片机的运动监测模块。本次设计主要组成是MSP430F149单片机电路、ADXL345加速度传感器、心率检测模块电路、LCD1602液晶显示电路、电源电路组成。通过ADXL345测量重力加速度，是用来判断人体状态，根据状态的数值变化进行计步功能。通过心率传感器测试，通过手指脉动放大经过比较器处理后发送给单片机进行心率采集。并将步数、心率显示在液晶LCD1602上。本次设计系统价格成本较低，功能比较全面，具有良好的市场前景。关键字：单片机；心率；步数；智能手环DesignofIntelligentSportsHandRingIIAbstractNowadays,withtheimprovementofpeople'slivingstandards,peoplehavegreaterconcernfortheirhealthproblems.Onlyagoodbodycanexperiencelife.Therefore,healthproblemsaregettingmoreandmoreattentionfromthepublic.Buthowcanweletthepublicbetterunderstandtheirphysicalandmentalhealth?Electronicinformationtechnologyandmedicinearedevelopingatthesametime.Thecombinationofthetwocansolvepeople'shealthproblems.Therefore,peopleneedmorehigh-precisionportablemedicalmonitoringinstruments.Humanmonitoringindicatorsgenerallypassthroughtwomajorindicatorsofheartratemeterstep.Forthisreason,amotionmonitoringmodulebasedonsingle-chipcomputerisdesignedaccordingtotheneedsofthedevelopmentofthetimes.ThisdesignmainlyconsistsofMSP430F149MCUcircuit,ADXL345accelerationsensor,heartratedetectionmodulecircuit,LCD1602LCDdisplaycircuit,powersupplycircuit.ThemeasurementofgravityaccelerationbyADXL345isusedtojudgethestateofhumanbodyandtomeasurethestepsaccordingtothenumericalchangesofthestate.Throughtheheartratesensortest,throughfingerpulseamplification,afterthecomparatorprocessingsenttotheMCUforheartrateacquisition.ThestepsandheartrateweredisplayedonLCD1602.Thisdesignsystemhaslowcost,comprehensivefunctionsandgoodmarketprospects.Keywords:MCU;HeartRate;StepNumber;IntelligentBracelet目录摘要.......................................................................................................................................................................IAbstract................................................................................................................................................................II第一章绪论........................................................................................................................................................11.1课题背景及其意义...............................................................................................................................1III1.2国内外的研究状况................................................................................................................................11.3本文的主要研究内容及论文结构安排.................................................................................................2第二章方案的设计与论证.................................................................................................................................32.1控制方案的确定...................................................................................................................
