摘　　要：为了满足独居老人的护理需求,解决老人摔倒后不能够及时得到救助的问题,设计了一种多传感器协同的摔倒智能检测系统。以STM32单片机为控制核心,通过加速度传感器和震动传感器检测加速度改变和身体震动情况来判断老人是否跌倒,同时利用心率传感器检测心率变化情况。传感器采集的数据经STM32主控芯片进行处理,判断老人当前的状态,若老人摔倒或心率异常,蜂鸣器报警并通过GSM模块向紧急联系人发送短信通知。仿真结果表明,老人在摔倒或心率异常时,系统能够及时报警并发送求救短信,尽可能降低对老人身体的伤害。In order to meet the nursing needs of elderly people living alone and solve the problem of not being able to receive timely assistance after falling,a multi-sensor collaborative fall intelligent detection system was designed.This system was based on the STM32 microcontroller as the control core,and used acceleration sensors and vibration sensors to detect changes in acceleration and body vibration to determine whether an elderly person has fallen.At the same time,it used a heart rate sensor to detect changes in heart rate.The data collected by the sensor was processed by the STM32 main control chip to determine the current status of the elderly person.If the elderly person fell or had an abnormal heart rate,the buzzer would sound an alarm and send a text message notification to the emergency contact person through the GSM module.The simulation results showed that when the elderly fell or had abnormal heart rate,the system could promptly alert and send distress messages,minimize the harm to the body as much as possible.
