摘要
心脏病是一种严重威胁人类生命健康的疾病,文中设计实现了无线心电检测与传输。在采集端,微弱心电信号经放大滤波后,通过ADC转化为数字信号,再由微控制器做进一步的数字处理与分析,最后通过无线模块和串口将数据发送出去。在接收端,通过无线模块获取到无线数据,再由串口将获取的数据发送到上位机以显示。该系统运行稳定、安全可靠,同时具有功耗低、操作简单、便于随身携带等特点,对心血管疾病的实时监测具有重要的意义。
Heart disease is a serious threat to human life and health. A wireless ECG sensor based on microprocessor was designed. In the acquisition end, after the amplifying filter, weak signal was converted into a digital signal through the ADC, and then further digitally processed and analysed by the mierocontroller. Finally, the signal was sent out by the wireless module and serial port. At the receiving end, wireless data were accessed via the wireless module, and then sent to the host computer to display by the serial port. The system is stable, safe and reliable. Meanwhile, it has the advantages of low power consumption, simple operation and portabilityon, and it has important significance to the real time monitoring of cardiovascular disease.
