摘要
为了能够及时发现病人的病情,对患有心血管类疾病的患者进行实时、有效的监护,设计实现了一种基于STM32的生理参数无线监测系统。系统由心电采集模块、血压采集模块、控制模块、数据发送模块和显示模块组成。心电信号由光电心率传感器SFH7050进行采集,血压信号由XGZP101SB1采集,通过STM32控制芯片对心电信号进行读取、滤波、运算等,再由蓝牙将生理参数数据无线传输到PC上位机。通过实验测得血氧器饱和度和心率值与专用医学监测仪误差在0.1%以内,血压测得平均误差在2%以内,结果表明该设计和医用设备有一致性,具有医学应用价值。
In order to discover the patient’s condition in time,and conduct real-time and effective monitoring of patients with cardiovascular diseases,the study has designed and implemented a wireless physiological parameter monitoring system based on STM32.The system consists of ECG acquisition module,blood pressure acquisition module,control module,data transmission module and display module.ECG signal is collected by the photoelectric heart rate sensor SFH7050,and blood pressure signal is collected by the XGZP101SB1.STM32 control chip is applied to actualize reading,filtering,computing and other processing of the ECG signal.Then Bluetooth is used to achieve wireless transmission of physiological parameters to the PC.Compared with the data from special medical monitor,the daviation of the blood oxygen saturation and heart rate value measured by experiment is less than 0.1%,and the average blood pressure measurement error is less than 2%.The data shows that the design and medical equipment has consistency and certain medical application value.
