摘要
基于STM32的用于老年人跌倒防护的装置,由控制模块,传感器模块,防护挽救模块组成。控制模块以STM32为核心,控制模块接收传感器模块检测的加速度、角速度信号,使用阈值判断法进行分析,并能够在老年人发生跌倒但未完全着地前为后面开启防护措施提供信号,从而避免老年人受伤害。实验显示,本系统采用的跌倒判断算法准确度高,系统可靠性高、结构简单。
Fall prevention device for elderly is composed of the control hardware device module, sensor module, prevention and saving module based on the STM32. Control module uses the STM32 as the core, which acquires sensor module detection signal and uses the threshold value judgment arithmetic to carry on the analysis The results of analysis can judge the fall action of elderly and provide signal to startup the prevention device before the elderly touching ground, so as to avoiding injured for old people The experiments show the judgment arithmetic of fall prevention has higher precision and reliability, simple, and easy to install.
