论文摘要
由于卡迪血管疾病（CVD）对人们的健康构成了严重威胁，因此长期心电图（ECG）监测对改善治疗具有很大的价值。为了实现远程的长期心电图监控，本文提出了低功率无线可穿戴的心电图监控设备。 ECG监视设备缩写为ECGM，是基于铁电微处理器设计的，该微处理器提供了超低功耗，并包含四个Parts-MCU，BLE，BLE，传感器和功率。 MCU部分是指MSP430FR2433的电路，ECGM的核心。 BLE部分是CC2640R2F模块用于收集的生物信号数据的无线传输。传感器部分包括几个传感器，例如用于监视生物信号和佩戴者运动的BMD101，而电源零件由电池电路，充电电路和3.3V/1.8V/4.4V电源电路组成。 ECGM首先从粘附到佩戴者胸部的织物电极中收集ECG信号，预处理信号以消除注入的噪声，然后通过蓝牙低能（BLE）将输出数据传输到佩戴者的手持手机。佩戴者可以在手机上获取ECG和其他生理参数以及一些相应的建议。系统的新颖性在于低功率ECG传感器芯片与铁电微观处理器的组合，从而实现了超低功耗和高信号质量。
Since cadiovascular disease (CVD) posts a heavy threat to people's health, long-term electrocardiogram (ECG) monitoring is of great value for the improvement of treatment. To realize remote long-term ECG monitoring, a low-power wireless wearable ECG monitoring device is proposed in this paper. The ECG monitoring device, abbreviated as ECGM, is designed based on ferroelectric microprocessor which provides ultra-low power consumption and contains four parts-MCU, BLE, Sensors and Power. The MCU part means circuit of MSP430FR2433, the core of ECGM. The BLE part is the CC2640R2F module applied for wireless transmission of the collected bio-signal data. And the sensors part includes several sensors like BMD101 used for monitoring bio-signals and motion of the wearer, while the Power part consists of battery circuit, charging circuit and 3.3V/1.8V/4.4V power supply circuit. The ECGM first collects ECG signals from the fabric electrodes adhered to wearers' chest, preprocesses the signals to eliminate the injected noise, and then transmit the output data to wearers' hand-held mobile phones through Bluetooth low energy (BLE). The wearers are enabled to acquire ECGs and other physiological parameters on their phones as well as some corresponding suggestions. The novelty of the system lies in the combination of low-power ECG sensor chip with ferroelectric microprocessor, thus achieving ultra-low power consumption and high signal quality.
