Design of Remote Physiological Parameter Test System Based on Wi-Fi and GPRS

设计了一种基于Wi-Fi与GPRS的远程生理参数测试系统。系统由传感器、控制、数据发送和显示等模块组成。心电信号由光电心率传感器进行采集,通过控制芯片对心电信号的读取、滤波、运算等处理,再由GPRS及Wi-Fi模块将数据无线发送到手机终端及相关医院的数据库中。显示设备在发送端自带液晶屏,能实时显示心电图、心率、血氧等数据。基于Android系统开发一款智能手机的APP,只要用一台智能终端,接入Internet网,便可以实时获取病人的心电图、心率、血氧饱和度、健康状况生理参数。实验结果表明,该系统和医用设备具有良好的一致性,且切实有效,具有一定的医学应用价值。

A remote physiological parameter test system is designed based on Wi-Fi and GPRS to give doctor patients＇ reliable real-time physiological parameters which may be used as a basis for treatment. The system is composed of the ECG acquisition module, control module, data sending module and display module. The ECG signal is collected by the optical heart rate sensor SFHT050, read, filtered, operated and further processed through the control chip STM32. Then data are sent to the mobile terminal and related hospital database by the GPRS and Wi-Fi wirelessly. An LCD screen is used as display device in the transmitter side to real-timely display ECG, heart rate, blood oxygen and other data. In addition, based on the Android system a smart phone APP is developed. By a smart terminal accessing to the Internet, doctor can real-timely access to a patient with his/her ECG, heart rate, oxygen saturation, health status physiological parameters. Experimental results show that the designed medical equipment has a good consistency and effectiveness, so has a certain degree of medical application value.
