可穿戴式水下生命体征与环境监测系统

Wearable underwater vital signs and environmental monitoring system

设计了一种能够在水下300 m的环境下正常工作的生命体征与海洋环境监测系统。系统集成多块传感器测量血氧饱和度、心率、心电信号和体温等生理指标以及海洋温度、电导率和压力等环境参数;采用可穿戴式一体化设计,将数据实时传输至腕部显示终端及水面上位机,供潜水员和水面工作人员监测;对采集到的光电容积脉搏波信号(PPG)和心电图信号(ECG)进行滤波处理,并进行了体温、心率、血氧准确度测试、水下通信稳定性测试、水下环境感知系统标定测试以及封装耐压测试。

A vital signs and marine environment monitoring system that can operate normally at underwater depths of 300 m is designed.The system integrates multiple sensors for measuring physiological parameters including blood oxygen saturation,heart rate,electrocardiogram signals,and body temperature,alongside environmental parameters such as ocean temperature,conductivity,and pressure.Utilizing a wearable,integrated design,it transmits data in real⁃time to a wrist display terminal and an upper computer on surface of water for monitoring by divers and personnel who work on surface of water.The collected photoplethysmography(PPG)and electrocardiogram(ECG)signals are filtered,and tests are conducted on body temperature,heart rate,and blood oxygen accuracy,underwater communication stability,underwater environment perception system calibration,and packaging pressure resistance.
