    摘要:

    针对家庭心电健康监护,以及提高低功耗心电监测系统监测的准确性,设计并实现了一种采用卡尔曼滤波的心电监测系统。该系统采用AD8232作为模拟前段对通过电极和三导联心电采集线提取的微弱心电信号进行滤波放大,再经STM32处理器进行卡尔曼滤波处理,最终在LCD得到清晰稳定的生物电信号及心率。经实验样机初步测试,在人体保持安静的情况下,LCD显示的心电信号清晰稳定,能够反映人体实际心电特征。结果表明该设计较好地完成了心电信号的滤波处理,能够满足家庭心电监测的需求,对于家庭医疗设备有一定参考价值。

    Abstract:

    Aimed at ECG health care for families,and improving the accuracy of the low power monitoring ECG monitoring system,an ECG monitoring system using Kalman filter is designed and implemented. The weak ECG signals are extracted by electrodes and ECG collecting line of three lead, and then filtered and amplified through the analog front using AD8232 , then the STM32 processor is used for Kalman filter processing. At last, the actual ECG characteristics of biological electrical signals and heart rate are got in the LCD.Tested by the experimental prototype,under the condition of the human body being quiet,the result in the LCD is clear and stable,and can reflect the actual electrical characteristics of the human body. The results show that the design successfully completed the ECG signal filter processing,can meet the needs of home ECG monitoring,which means a certain reference value for family medical equipment.
