摘要
老人摔倒可能导致严重后果.鉴于此,开发一种基于云端的老人摔倒检测和告警系统或可避免此类问题.该系统采用STM32F103C8T6单片机作为主控,用传感器MAX30100采集老人的心率和血压值,传感器MPU6050采集老人摔倒的角度及加速度,A/D转换器转化为数字量,借助I2C总线把数字量送至微控制器,用ATK-1218-BD模块实现老人定位,ESP8266-01模块将采集的数据上传至云端,通过手机APP显示.系统可以监测老人当前状态,快速辨别其身姿,获取位置信息,满足实时监测和摔倒报警的要求.测试结果表明:系统总体布局合理,方案可行,运行稳定,误差不超过1%,实现了较精准的身姿识别,达到摔倒报警及远程监测的目的.
Abstract
A fall of the elderly may result in serious consequences,in view of which,a cloud-based fall detection and alarm system for the elderly may avoid such problems.The system adopted STM32F103C8T6 as the microcontroller.The sensor MAX30100 collected the heart rate and blood pressure of the elderly,while sensor MPU6050 monitored their angle and acceleration.Data were converted to digital quantity through A/D and sent to MCU through I2C bus.The ATK-1218-BD module was used to locate the elderly and data were uploaded to the cloud using ESP8266-01 module.The system was able to monitor the current status of the elderly,identifying their posture quickly,and obtaining the lo-cation information to meet the requirements of real-time monitoring and fall alarm.The overall layout of this system was reasonable,the scheme was feasible,the operation was stable,and the systematic errors were less than 1%.The system can obtain more accurate posture identification,and achieve the goal of fall alarm and timely remote monitoring of the elderly.
