摘要
针对目前市面上的心电图监测设备存在体积庞大、价格昂贵等问题,设计了一款轻便小巧,价格相对便宜,操作简单的心电监测系统。本设计使用AD8232方案作为模拟前端,通过STM32单片机对心电信号进行处理,最后通过OLED屏幕,或者通过蓝牙与上位机等终端设备连接来显示心电图及心率,从而实现心电监测的基本功能。经实际测量的结果显示,本设计在使用上满足应用的测量精度同时也非常便捷,有较高实用价值。
Aiming at the problems of large and expensive ECG monitoring equipment on the market,a light and compact ECG monitoring system with relatively low price and simple operation is designed.This design uses the AD8232 solution as the analog front end,processes the ECG signal through the STM32 microcontroller,and finally displays the ECG and heart rate through the OLED screen or through Bluetooth and the host computer and other terminal devices to realize the basic function of ECG monitoring.The actual measurement results show that the design meets the application’s measurement accuracy in use and is also very convenient,with high practical value.
