基于单片机的跌倒检测报警系统设计

当代社会,老年人群健康安全监护的需求日益增加,老年人跌倒检测的研究成为社会关注热点。故文章设计了一种基于单片机的跌倒检测报警系统,选用STC89C52单片机作为控制芯片、ADXL345传感器作为检测模块以及GSM发送装置作为通信模块。首先,利用检测模块采集老人日常活动中的运动数据,经模数转换后将其发送给单片机,以判断老年人当前状态。当满足触发条件时,报警模块发出声音提醒老人和周围的人,并将求救短信发送到相关人员手机上。本设计有耗能低、易携带、传输距离远等特点,为老年人的安全防护提供一种智能手段。

In today’s,the demand for health and safety monitoring of the elderly population is increasing.The fall detection system can effectively detect the occurrence of falls in the elderly and promptly report the alarm to protect the health and safety of the elderly.This paper presents a fall detection and GSM alarm system based on the ADXL345 tilt sensor.The ADXL345 inclination sensor collects the inclination data generated by the elderly in daily activities in real time,and then sends the data to the microcontroller STC89C52 for processing and judging the exercise state of the elderly.When the system detects the occurrence of a fall,an alarm sound is issued to remind the elderly and the surrounding people and an alarm message can be sent to the relevant person’s mobile phone.
