中文摘要:
      为实时无线监测人体心率,提出了一套基于低功耗蓝牙技术的无线心率计设计方案。该心率计主要由主控芯片CC2541芯片通过IIC接口连接传感器Max30100,控制采集并读取人体腕部脉搏波数据;CC2541作为一款支持低功耗蓝牙协议的单片机芯片,能将脉搏波数据传送至蓝牙主机设备。提出了一种改进的R波检测方法,该方法通过加入对心率基频及其谐频的分析,有效减少R波误判。多次实测表明,该心率计可稳定实现心率测量与无线传输,具有功耗低、精度高、快速测量、实时监测等特点。
英文摘要:
      For the real time wireless monitoring of human heartrate, this paper presents a design of wireless power monitor based on Bluetooth Low Energy technology. The chip CC2541 is used to control the acquisition and read the data of wrist pulsewave; CC2541 as a microcontroller chip supports the BLE protocol, which can transmit the pulsewave data to the BLE host device. In this paper, an improved R wave detection method is proposed. By analysing the fundamental frequency and harmonic of heartrate, this method can reduce the R wave misjudgment effectively. Through several measurements show that the heart rate monitor can achieve heart rate measurement and wireless transmission, with stable,low power consumption, high precision, rapidly, real time.
