摘要
社会经济不断发展的过程中，人口老龄化也在不断加速，老年人的健康问题逐渐受到大众的关注。老年人各项生理指标开始衰退，心脑血管疾病频发，作为老年人致死率较为严重的问题之一，跌伤伤害逐渐成为大众性问题。为了加强老年人对于自身健康的关注度，提高突发情况下的救助力度。此次设计利用单片机作为老人防跌倒报警监护系统的控制核心，负责协调各个模块完成整个系统的功能。采用温度传感器来对老人体温进行测量，采用PULSESENSOR心率传感器来对用户心率进行检测，利用HX711压力检测模块来进行血压检测操作，利用ADXL345陀螺仪传感器来用户的身体状态进行辨别。实际检测中，是时间检测到的心率数据、体温等数据信息通过显示进行显示，便于用户实时观测。当检测到用户摔倒，则触发GSM驱动程序在SIM800CGSM模块的工作下进行报警操作，并显示老人摔倒的具体定位信息，便于及时进行救援工作。在硬件电路设计以及软件功能调试的过程中，完成整体系统设计，同时在实物功能演示中，整体设计基本满足预期目标，能够实现各项数据的检测操作，在实际应用中具有一定的设计意义。
