基于ZigBee的无线传输脉搏检测系统设计

目的：设计了一种基于ZigBee技术的无线传输脉搏检测系统。方法：由CC2430控制单元将脉搏传感器采集到的人体浅表动脉处的搏动信号通过模拟电路的预处理，经数模转换后得到数字信号，再将转换后的数字信号传给控制和显示单元中的信息处理单元．进行处理和显示，同时将数据通过ZigBee无线通讯单元发送到上位机，由上位机存储数据，供医护人员检索和回放。结果：实验表明，此系统能够对人体的脉搏信号进行实时采集，同时可通过ZigBee无线网络进行实时、安全、可靠的通信。结论：该检测系统通过运用ZigBee无线通信技术，可以通过人体随身携带的无线终端采集到脉搏数据．使采集系统具有移动性，因此能广泛适用于健康运动监测、医院移动监测等领域。

Design of the Pulse Wave Measurement System Based on ZigBee Wireless Network

Objective To design a pulse wave measurement system based on ZigBee wireless technology.Methods CC2430 controlled by the pulse sensor unit will be collected in pulsatile signal to human superficial artery through analog circuit preprocessing, which could be transformed into digital signal in digital model, and then can be impressed and displayed by control unit to deal with and display, at the same time, data in ZigBee wireless communication data unit is sent to the host computer and these data would be retrieval and playback of medical workers. Results The experiments show that the system is able to acquire the pulse wave of the human body in real-time, at the same time, through the ZigBee wireless network, it can be real-time, secure and reliable communications. Conclusion It is applicable to a wide range of health movement monitoring, monitoring of mobile hospitals and other areas.
