中文摘要：

阐述了一种基于STM32的智能防跌倒看护系统，由主机和从机组成，二者通过蓝牙通信。主机主要实现了计步、跌倒检测、定位等功能，从机主要实现了发送求助短信、测心率、一键呼救、接电话和显示等功能。本文给出了基于陀螺仪MPU6050和微控制器STM32F103C8T6的系统总体框架、硬件和软件设计，以及一些检测算法的设计。实验表明，该系统的误判率极低、实时性高、数据准确，可广泛应用。

英文摘要：

An intelligent device of care system based on STM32 is introduced in this article. The device is made up of host system and the slave system. The communication mode between the two parts is based on bluetooth. Functions like steps-counting, falling detection, satellite positioning etc are realized on the master system and the functions like message sending, calling, alerting and pulse monitor are realized on the slave system. This article shows the hardware and software designs of the system based on MPU6050 and STM32F103CST6. The experiments show that this system has a lower rate of erroneous judgment ; it also has advantages of real-time processing and accurate data, so it can be widely used in our life.
