基于STM32和GSM的老年人摔倒智能急救报警系统的设计与应用

Design and application of intelligent detection and alarm system for elderly fall based on STM32 and GSM

目的根据疗养院实际工作需要,通过设计跌倒特征算法,实现基于STM32和GSM的智能摔倒急救报警系统的研发。方法通过三轴加速度传感器,采集重保对象日常行为参数。一旦瞬时加速度超过阈值,STM32单片机将会启动GSM模块,拨打预设电话号码,完成跌倒报警。结果通过多次跌倒检测实验,检测正确率接近100%。结论该系统功耗低,工作稳定,成本低廉,为高龄疗养员疗养期间的安全保障起到了重要作用,也确保了医护人员疗养任务的顺利开展。

Objective According to the actual work needs of sanatorium,the intelligent fall detection and alarm system based on STM32 and GSM was developed by designing fall feature algorithm.Method The daily behavior parameters of the most important protected objects were collected through the three-axis acceleration sensor.Once the instantaneous acceleration exceeded the threshold,the STM32 MCU would start the GSM module to dial the preset telephne number to complete the fall alarm.Result Through many fall detection experiments,the detection accuracy was close to 100%.Conclusion The system has low power consumption,stable work and low cost.It plays an important role in ensuring the safety of elderly convalescents during convalescent period,and also ensures the smooth development of convalescent tasks for medical and nursing personnel.
