摘　　要：系统以MSP430FG439超低功耗微处理器为核心,结合低功耗射频收发器CC2500,实现了心电数据的采集、处理以及无线传输,点阵LCD显示操作界面、心电波形和相关结果。此外当处理器检测到异常波形时,可以将数据无线传输到上位机进行进一步的诊断,这种方式使得无线便携成为可能。由于采用了高集成度的微处理器,简化了系统的心电采集前端模拟放大电路。测试结果显示系统采集的心电波形特征波明显,可用作相关疾病的智能诊断。本系统具有功耗低、体积小、精度高、使用方便等特点。In this paper, we present a MSP430FG439-based portable wireless ECG monitoring system. Via RF transmitter chip CC2500 with low power ECG data was collected, analyzed and transmitted in real time and displayed on a LCD. Any anomalies will be transferred when the proeesser detected abnormal waveform, the date was transmitted on PC via RF transmitter chip CC2500 for further analysis. Highly integrated processor MSP430 significantly simplified the front-end analog amplifier circuits. The experimental results indicated that the system could provide a preliminary diagnostic information for some heart diseases based the characteristics of the ECG waveforms. In addition, the system has the advantages of low power consumption, small size, high precision and easy operation.
