脉搏信号无线采集装置

Wireless Acquisition Device of Pulse Signal

针对脉搏信号无线传输和在线监测的问题,设计了一种基于ZigBee的无线脉搏信号采集装置,利用双极性放大器OP07对脉搏信号进行滤波、放大和升压处理,利用片上系统芯片CC2430对调理后的信号进行采集和无线传送,并利用VC++设计了上位机监测界面,整个系统能够实现对脉搏信号的实时采集,并无线传送至监测中心进行显示和数据分析,该系统利用ZigBee协议进行通信,能够满足实际应用中的低功耗、低成本以及高可靠性的要求.

This paper designs a kind of wireless pulse signal acquisition device based on ZigBee which aims at solving wireless transmission and online monitor problem. It uses the bipolar pulse amplifier O1＇07 to filter, amplify and boost the pulse signal. Use the chip CC2430 to collect and wirelessly deliver the processed signal and design monitor PC interface using VC ＋＋, so the whole system can achieve real-time collection on the pulse signal and can wirelessly transmit it to the monitor centre to analyze the data. The system utilizes the ZigBee protocol for communi- cation, which meets low power, low cost and high reliability requirements.
