基于北斗定位技术的远程心率监控系统设计

Design of Remote Heart Rate Monitoring System Based on Beidou Positioning Technology

设计实现了一种基于北斗定位技术和STM32F103的远程心率监控系统。系统主要由心电信号采集和处理模块、TFT触摸屏、北斗定位模块、GSM模块等组成。心电信号采集由压电陶瓷片的正压电效应实现,经过仪表放大器放大后,通过多回路负反馈滤波电路,获取频率范围为0.3~3 Hz的心电信号。显示模块采用TFT触摸屏,可以显示日期、时间、心跳次数、经度、纬度信息等内容。北斗定位模块获取用户所在的地理坐标,GSM模块将健康信息和地理位置信息以短信的形式发送给用户的监护人和医生,从而实现远程心率监护。

A remote heart rate monitoring system based on Beidou positioning technology and STM32F103 is designed for the outdoor patient, whose location and condition such as an irregular heartbeat can be timely sent to the rescuer. It is mainly composed of ECG signal acquisition and processing module, Beidou positio-ning module,GSM module and TFT touch screen module. The ECG signal is firstly acquired by the positive piezoelectric effect of piezoelectric ceramic plate, and then amplified by the instrumentation amplifier, finally the frequency range 0. 3 ~ 3 Hz of ECG signals are obtained through multi - loop negative feedback filter cir-cuit. The TFT touch screen module can display the date, time, the heartbeat, latitude and longitude informa-tion,etc. The Beidou positioning module can get the user^s geographic coordinates of the users. At last the GSM module sends the user 爸 health infonnation and location infonnation to guardian and doctors in the form of text messages,so as to realize remote heart rate monitoring.
