摘　　要：当前市场上大部分低功耗蓝牙(Bluetooth Low Energy,BLE)心率计只能同与之配套的App一起使用。本文研究并设计了基于BLE的开放式心率计,其选用心率传感器MAX30102采集光电容积脉搏波(Photoplethysmography,简称PPG),并通过控制器处理原始PPG信号和计算心率,最后利用BLE实现心率计与开放式运动健康App或运动手表的连接、配对、绑定以及心率数据传输。测试结果表明,本文设计的心率计能快速准确地测量心率,并通过BLE链路在开放式App或运动手表上显示心率。Most of the BLE heart rate devices in the current market can only be used in the matching Apps.An open-ended heart rate de- vice which based on BLE is researched and designed in this paper.MAX30102 sensor is selected to collect the PPG raw signal.The original Photoplethysmography（PPG）signal is processed and the heart rate is calculated via the microcontroller.The function of Bluetooth connection, pairing, binding and heart rate data transmission between heart rate device and fitness Apps or fitness watch is implemented on the basis ofBLE.The experimen- tat results reveals that the heart rate device designed in this paper can measure heart rate accurately and successfully display heart rate data on fitness Apps and watch under the BLE link.
