目? 录
?摘? 要
随着生活水平的提高，无论是老年还是青壮年群体，人们对于健康越来越重视。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血氧血氧计步3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STM32单片机电路、ADXL345加速度传感器、心率血氧血氧检测电路、OLED液晶显示电路、电源电路、时钟DS1302和DS18B20温度传感器组成。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。通过心率血氧传感器测试，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血氧采集。并将步数、心率血氧，温度、时间显示在液晶LCD1602上，并且我们也可以通过蓝牙把当前的数据发生到手机端进行显示，这样也方便陪练人员随时观察运动者状态。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 词：STM32；单片机；DS18B20温度传感器；计步器；液晶显示
With the improvement of living standards, people pay more and more attention to health for both the elderly and the young. Only a good body can experience life, but how can the public better understand their physical and mental health? Electronic information technology and medicine are developing at the same time. The combination of the two can just solve people's health problems. Therefore, people have a greater demand for high-precision portable medical monitoring instruments. For this reason, according to the needs of the development of the times, a motion monitoring module based on MCU is designed.
This design is mainly composed of STM32 MCU circuit, adxl345 acceleration sensor, heart rate detection module circuit, OLED liquid crystal display circuit, power supply circuit, clock DS1302 and DS18B20 temperature sensor. Through adxl345 measurement of gravity acceleration, is used to judge the state of the human body, according to the numerical changes of the state of step counting function. Through the heart rate sensor test, through the finger pulse amplification, after the comparator processing, sent to the MCU for heart rate acquisition. The steps, heart rate, temperature and time are displayed on LCD1602. This design system has low price and cost, comprehensive functions and good market prospects.
KEY WORDS: STM32; Single chip microcomputer; DS18B20 temperature sensor; A pedometer; Liquid crystal display
