摘　　要：本文针对强运动环境设计了一种可穿戴运动体征监测系统。选用ADS1292型模数转换器芯片作为心电(ECG)信号采集模块,LMT70型温度传感器芯片作为体温信号采集模块,ICM20602型6轴陀螺仪作为加速度测量模块,可穿戴于人体实现动态心电监测、体表温度采集以及运动步数和运动距离测量。针对强运动导致的基线漂移对心电信号检测的影响,设计了归一化最小均方(NLMS)自适应滤波器进行滤除。测试结果表明,本设备测试精度较高,抗基线漂移能力较强。A wearable system for monitoring physical signs during intense exercise was developed.The ADS1292 analog-digital converter chip is utilized for ECG signal acquisition.The LMT70 temperature sensor chip is used for temperature signal acquisition,and the ICM20602 six-axis gyroscope serves as the acceleration measurement module.This system can be worn on the body to enable dynamic ECG monitoring,surface temperature acquisition,and movement step and distance measurement.To address baseline drift caused by vigorous motion during ECG signal detection,a normalized least mean square(NLMS) adaptive filter has been designed to eliminate it.Test results demonstrate that the device exhibits high accuracy and robust anti-baseline drift capability.
