可穿戴的心率和血氧监测耳机设计

Design of wearable headset system monitoring heart rate and blood oxygen

设计一款穿戴式的心率血氧健康监测耳机系统,完成了硬件设计和软件设计,并实现三个主要功能:信号采集;计算脉搏波输出波形数据以及实时的心率和血氧值;并将数据通过蓝牙模块发送到上位机。测试者通过上位机软件输出的结果,实现对自身健康的实时监测。对比设计的穿戴式健康监测耳机与标准的心率血氧监测仪测试结果,误差在允许范围内,验证了该设计的准确性。

This paper proposes the design of wearable headset system monitoring heart rate and blood oxygen, and completes the hardware and software design. The three main functional parts are as follows : the acquisition of signals, the calculation of the output data in pulse wave and the real-time heart rate and blood oxygen value; and the delivery of data from the Bluetooth module to the upper monitor. The testers achieve the real-time oversight through the results of the software of the upper monitor. In comparison with the designed system in the paper and the standard system, the errors are within the allowable range, which validates the accuracy of the design.
