摘要
应对当前心电信号(ECG)监测系统的不足,设计了一种基于穿戴式心电信号监测系统,系统架构由AD8232生物芯片、超低功耗微控制器MSP430FR5738以及Micro—SD卡组成。详细介绍了系统软硬件的具体设计,并提出了一种动态双阈值的实时心率提取算法。通过对于本系统的功耗测试与实时心率算法的验证,得出本系统具备体积小、低功耗等穿戴式设备的优越性。
To deal with shortcomings of current ECG monitoring system,design an ECG monitoring system based on wearable device. This system is mainly composed of an AD8232 biochip,ultra low power consumption Microcontroller MSP430FR5738 and a Micro-SD card. Introduce the specific designs of system software and hardware are introduced detailedly and a realtime heart rate extraction algorithm is proposed with dynamic double threshold value. By testing power consumption of this system and by verifying realtime heart rate algorithm,it is concluded that this system has many advantages of wearable devices,such as small volume and low power consumption.
