摘要:针对传统的心率、血氧饱和度检测方法在现代医院的应用中存在的缺陷和不足问题,开发了
一种基于 LoRa 的心率血氧实时监测系统。该系统包括一组患者佩戴的心率血氧实时监测手环和
与 心 率 血 氧 实 时 监 测 手 环 通 过 LoRa 基 站 连 接 的 服 务 器 。 心 率 血 氧 实 时 监 测 手 环 以
STM328L151CBU6A 作 为 处 理 器 ,集 成 MAX30102 脉 搏 波 传 感 器 、SX1278 芯 片 等 。
STM328L151CBU6A 处理器首先对 MAX30102 采集的脉搏波信号进行预处理,然后通过心率血氧
算法计算出心率血氧值并判断异常与否,SX1278 芯片通过 LoRa 无线方式将心率血氧值或异常信
号传输至 LoRa 基站,LoRa 基站将数据或异常信号通过以太网的方式传输至服务器,服务器对接收
到的数据或异常信号进行处理和存储,供每个护士站对每个患者的心率血氧状况进行实时的监
测。实验表明,该系统传输网络稳定可靠、复杂环境传输距离远,对心率、血氧的监测准确度较高。

Abstract: Aiming at the shortcomings of traditional heart rate and blood oxygen saturation detection
methods in modern hospitals,a real- time monitoring system of heart rate and blood oxygen based on
LoRa was developed. The system consists of a real-time heart rate and blood oxygen monitoring wristband
worn by a group of patients and a server connected to a LoRa base station by a real-time heart rate and
blood oxygen monitoring wristband. STM328L151CBU6A is used as the processor of the wristband for
real-time monitoring of heart rate and blood oxygen,and integrated with MAX30102 pulse wave sensor
and SX1278 chip. Firstly STM328L151CBU6A processor preprocesses the pulse wave signals collected
by MAX30102,and then calculates the heart rate and blood oxygen value by heart rate and blood oxygen
algorithm and judges whether the result is abnormal or not. SX1278 chip transmits the heart rate and
blood oxygen value or abnormal signal to LoRa base station by LoRa wireless mode,and LoRa base
station transmits the data or abnormal signal to the server by ethernet. The data or abnormal signals
received by the server are processed and stored for real- time monitoring of heart rate,blood oxygen
status of each patient in each nurse station. The experiments show that the system has stable and reliable
transmission network,long transmission distance in complex environment,low power consumption of
wearing equipment,and high accuracy of heart rate and blood oxygen monitoring.
