基于ZigBee的无导联线动态心电监测系统设计

为克服传统的有导联线动态心电监测装置导线连接复杂，影响心电信号采集的质量，使患者受限、产生束缚感等不足，设计了一种基于ZigBee的无导联线动态心电监测样
机。该系统主要由信号采集模块和无线传输模块组成，采集到的心电信号通过CC2530自带的A/D转换成数字信号并通过无线模块发送，经 ZigBee 无线传输后，由接收模块接收心电数据并通过串口上传至PC机实时显示。给出了硬件电路的设计方案及软件程序流程图，并在实验室环境下对该样机进行了测试，实现了心电信号的无导联线监测和心电波形的实时显示。该样机具有功耗低、成本低、重量轻和体积小等特点，心电波形失真度较小，可满足临床分析与诊断的要求。

Wireless Dynamic ECG Monitoring System Based on ZigBee Technology

The traditional dynamic ECG(ElectroCardioGram) monitoring device is complex due to many wire connection.The patients body is lim ited resulting in a sense of restraint and the quality of ECG is affec ted.To overcome these drawbacks,we designed a wireless dynamic ECG monito ring device based on ZigBee.The device has the advantages of low power consumpti on,low cost,light weight,and small size.It is mainly composed of a signal acquis ition module and wireless transmission module.The acquired ECG signals are conve rted to digital signals by the A/D in CC2530,and sent through the wireless module.Via ZigBee wireless transmission,the ECG signals are received by re ceiving module and uploaded to PC machine in serial for real-time display. This study describes the design of the hardware circuit,and gives the flow char t of software program.The device has been tested in the laboratory,and th e real-time ECG waveforms show that the achieving ECG signals with li ttle distortion can be used for clinic analysis and diagnosis.
