摘　　要：为了有效地解决独居老人由于突发性病症而得不到及时救治的问题,本系统以STM32W108无线射频芯片为核心处理器,提出了的一种心率实时监测和跌倒检测的解决方案。该系统利用ECG信号中的QRS波提取心率,同时分析三轴加速度传感器的信号,结合运动状态变化(SVM、DSVM)和姿态特征变化(姿态角)判断是否跌倒。该设备通过模拟测试证明了其可靠性和实用性。In order to solve the problem that the old solitary man can＇t get the treatment in time when they fall ill suddenly, the system use the STM32W108 radio frequency chip as the core processor, which is used to monitor the heart rate and the fall incident. The system extracts the heart rate based on the QRS wave in ECG signal while determines whether the elderly have a fall depended on the analysis on the signal from the three axis acceleration sensor combined with the change of motion state and the attitude features. The device has been proved to be reliable and practical with the simulative test.
