| 摘 要： | 提出了基于ZigBee无线网络的脉搏信号测试系统,包括脉搏传感器、信号调理、ZigBee网络节点、数据采集部分.根据人体脉搏信号属于非平稳信号的特点,提出了基于Choi-Williams分布(CWD)的脉搏信号时频分析方法.实验结果表明,本系统能够对人体的脉搏信号进行实时采集,CWD分布信号处理能很好地反映脉搏信号所包含生理病理的信息;如果同临床医学病例结合起来,将有很好的应用价值.

| Abstract: | Provided the pulse wave measurement system based on ZigBee wireless sensor network.Pulse sensor,signal process circuit,ZigBee nodes and data sampling block were included in this system.As the pulse signals were non-stable signals,the method based on Choi-Williams distribution(CWD) was used for pulses signals analysis.The results of test verify that the system run well for the real-time pulse monitoring and that CWD is a good way to analyze the pulse signals.The system will provide wide pratical application combining with the medicine. |
