便携式心电监护仪的设计

Design of Portable ECG Monitor Based on Community ECG Monitoring System

根据社区医疗监护的发展趋势,设计了一款基于嵌入式系统的便携式心电监护仪。以MSP430单片机为核心处理器,将采集到的心电信号经心电采集电路的处理后,通过液晶实时显示心电波形和相关数据。以SD卡作为数据存储设备,通过ZigBee无线通信设备进行数据传输。该设计充分利用了MSP430单片机功耗低、体积小的优势,将其应用在社区心电监护系统中,为社区医疗和家庭监护提供了一种有效的解决方案。

According to the development tendency of community medical monitoring system,a portable ECG monitor based on embedded system was introduced.The MSP430 was used as the core processor,collection of ECG signals was processed through the ECG circuit,wave form and relevant data were displayed on the LCD in real-time,and SD card was employed as the data storage device.All the data were transferred through the Zigbee wireless telecommunication device.The monitor takes full use of the advantages of the MSP430,which is low in power consumption and small in volume,has wide application in community ECG monitoring system,and provides an effective solution to community medical care and home monitoring.
