老人防跌倒报警器设计

Design of Alarm Device for Preventing Falling of the Elderly

近年来,我国人口老龄化日益严重,许多家庭都出现了空巢老人,老人出行安全成了很大的问题,老人防跌倒报警器显得尤为重要。主要介绍了一种老人防跌倒报警器的设计方案,整个系统的研究方法、工作原理及设计过程,包括硬件和软件设计。其中硬件设计包括单片机控制模块、电源模块、ADXL345跌倒检测模块、OLED液晶显示模块、GPS模块、GSM/GPRS模块、蜂鸣器模块、心率检测模块。通过对制作实物测试表明,系统性能可靠,实现了帮助盲人出行的设计目标。

In recent years,China’s aging population problem is becoming increasingly sever,With the number of empty nesters growing,the elderly travel safety has become a big problem and the elderly fall alarm is particularly important.This paper mainly introduces a kind of old man fall alarm design scheme that composes of the research method and working principle of the whole system and the whole design process,including hardware design and software design.The hardware design includes single-chip control module,power module,ADXL345 fall detection module,OLED liquid crystal display module,GPS module,GSM/GPRS module,buzzer module,heart rate detection module.The practical test shows that the system has reliable performance and realizes the target of helping blind people travel.
