可穿戴式体温监测预警系统设计

Design of wearable body temperature monitoring and early warning system

设计了一种可穿戴在腕部的体温监测预警系统,可用于新冠肺炎集中隔离人群的体温监测,也适用于需要连续监测体温的场景和常见情况下使用。以单片机为核心进行设计,温度采集模块采集腕部体表温度和外界环境温度,通过最小二乘法拟合的方式补偿环境温度对腕部温度的影响,然后通过蓝牙模块以无线方式传输到手机端。手机端可以实时显示体温值,温度异常时会显示异常提醒,同时可查看历史体温数据。经测试该系统测量误差小于0.1℃,且稳定性好,实时性高,视觉效果良好,易于功能扩展。

A novel coronavirus pneumonia monitoring system was designed for monitoring the temperature of the COVID-19 with a centralized isolation population.It also applies to scenes requiring continuous monitoring of body temperature and common use.The design was based on MCU,the temperature acquisition module collected the wrist surface temperature and the external environment temperature respectively,compensated the influence of the environment temperature on the wrist temperature by the least square fitting method,and then transmited to the mobile phone through the Bluetooth module.The mobile terminal could display the body temperature value in real time.When the temperature was abnormal,it could display the abnormal reminder and view the historical temperature data.After testing,the measurement error of the system is less than 0.1℃,and it has good stability,high real-time performance,good visual effect and easy function expansion.
