提高老人医护安全的可穿戴心率测护仪设计

Design of Wearable Heart Rate Monitor to Improve the Safety of Elderly Medical Caring

为实现对患有心梗的老年人身体状况的自动化管理以及减轻监护人对特殊人群的监护压力,文章设计了一种老年人的实时监测系统;该系统以Arduino以及32位的STM32F103单片机控制,采用ADS1292、LMT70传感器通过AD采集电位电压数据,利用放大电路和信号处理电路等转换为心率以及温度值,ESP8266无线传输模块在建立TCP连接之后,将数据传送至服务器和将数据传送至OLED显示终端,实现了当监护人不在床前陪护的情况下,依然能够将老年人的身体状况信息传送到监护人的手机APP中,有效防止了在发生意外时,不能及时采取措施的情景;该设计经过测试表明,心率的测量准确度高达95.29%,体表温度的测量准确度高达99.937%;测试结果表明,该设计具有足够高的准确性以及可靠性,具有实际推广与应用价值。

In order to realize the automatic management of the physical condition to the elderly with myocardial infarction,and reduce the pressure of guardianship on the special human,a real-time monitoring system is designed for the elderly.This system is controlled by Arduino and the 32-bit STM32F103 microcontroller.The potential voltage data is collected by the sensors ADS1292 and LMT70.The voltage data is converted to heart rate and temperature value by AD convertor,the amplification and signal processing circuits.ESP8266 wireless transmission module is used to transfer data to the server and transfer data to OLED display terminal based on establishing the TCP connection.The designed system can transmit the elderly's physical condition information to the guardian's mobile phone APP,it can effectively prevent the accident of no taking measures timely when the guardian is not in bed escort.The experiment shows that the heart rate measurement accuracy up to 95.29%,body surface temperature measurement accuracy up to 99.937%.The test results indicate that the system has high accuracy and reliability,and has practical popularization and application value.
