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。

英文摘要 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.
