心电监护仪能长时间连续记录心电数据,一直以来是医院病房不可缺少的医疗仪器，如今在家庭中的应用也越来越普及。基于ARM微处理器，设计开发了一种心电监护仪。采用AD8232作为ECG前端采集芯片来获取心电信号，结合放大、滤波电路，将前端信号放大后再进行滤波除噪处理。使用STM32微处理器作为心电信号处理芯片，对心电信号进行模数转换，通过蓝牙模块ATKHC05发送至智能终端，实现在智能终端上的心电图形绘制与实时显示。系统设计中，充分考虑了心电电极的导联脱落检测以及低功耗模式实现，因此实现的心电监护仪具有数据准确，携带便捷等优点，必将在市场上得到广泛使用。
The ECG monitor can continuously record the ECG data for a long time, so it has been an indispensable medical instrument in hospital wards. And now it is more and more popular in the family. An ECG monitor is designed and implemented based on ARM microprocessor in this thesis. AD8232 is used as the ECG frontend acquisition chip to obtain the ECG signal, and the signal is filtered and denoised after being amplified by amplifier and filter circuit. The ECG signal is converted from analog to digital using the STM32 microprocessor as signal processing chip and sent to the smart terminal through the Bluetooth module ATKHC05. Then electrocardiogram can be drawn and display in real time in the smart terminal. In the design of the system, the detection of lead drop and the realization of low power consumption mode are fully considered, so the ECG monitor will be widely used in the market because of its accurate data, light weight and so on.
