Heart rate detection system based on smart mattress

针对现有智能设备对睡眠过程中的心率检测效果不够理想,以及常用的检测方案有很多条件限制、无法普遍适用于大部分情况的问题,文章设计一款基于智能床垫的心率检测系统,介绍了该系统的硬件设计与信号处理过程。该系统包括数据采集、数据传输及上位机数据处理等功能,其中数据处理模块采用基于奇异值分解的算法,针对心跳信号特征进行有效成分提取和幅值修正。测试实验结果表明检测结果真实可靠。

Existing smart devices are not ideal for detecting heart rate during sleep.Commonly used detection schemes require strict conditions,and cannot be generally applied in most situations.To cope with these problems,a heart rate detection system based on smart mattress is proposed.The complete process from hardware design to signal processing is introduced.The system function includes signal acquisition,signal transmission and data processing on the host computer.The data processing module employs the singular value decomposition algorithm,which extracts effective component and corrects the amplitude of the heartbeat signal.The results of the experiment prove the reliability of the system.
