摘要:

系統(tǒng)以MSP430FG439超低功耗微處理器為核心,結(jié)合低功耗射頻收發(fā)器CC2500,實(shí)現(xiàn)了心電數(shù)據(jù)的采集、處理以及無(wú)線傳輸,點(diǎn)陣LCD顯示操作界面、心電波形和相關(guān)結(jié)果。此外當(dāng)處理器檢測(cè)到異常波形時(shí),可以將數(shù)據(jù)無(wú)線傳輸?shù)缴衔粰C(jī)進(jìn)行進(jìn)一步的診斷,這種方式使得無(wú)線便攜成為可能。由于采用了高集成度的微處理器,簡(jiǎn)化了系統(tǒng)的心電采集前端模擬放大電路。測(cè)試結(jié)果顯示系統(tǒng)采集的心電波形特征波明顯,可用作相關(guān)疾病的智能診斷。本系統(tǒng)具有功耗低、體積小、精度高、使用方便等特點(diǎn)。

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 processer 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.
