基于STM32的老年人摔倒检测系统的研究

Research on the Fall Detection System for the Elderly based on STM32

近年来,中国已进入老龄化社会,且老龄化进程不断加快,而摔倒已成为老年人受到伤害的重要原因之一。文章采用意法半导体的STM32F103系列单片机为平台,设计了1套摔倒检测装置,通过检测人体行为动作的加速度以及加速度的变化率为判断指标,集摔倒检测、体温、心跳速率以及血氧浓度检测、短信报警、定位等功能与一体。经测试表明,所设计的系统具有成本低、功耗低、识别率高的特点。

In recent years, China has entered an aging society and the aging process has been accelerating.Falling down has become one of the main causes of injuries to the elderly. In this paper, STM32F103 series microcontroller was used as the platform to design a set of fall detection device.By detecting the acceleration of human action and the rate of change of accel- eration, the system integrated the functions of fall detection, body temperature, heart rate and blood oxygen concentration de- tection, message alarm, positioning and so on.The test showed that the designed system has the characteristics of low cost, low power consumption and high recognition rate.
