|
摘要
进行一种物联网型血压无线监测系统的研制,设计并制作了本系统的无线数字血压计硬件部分,通过气压传感器MPX5050GP和外围电路完成血压测量信号的采样,将两路血压测量振荡波法使用的信号通过STM32F407VGT6 MCU A/D转换及比值法算法计算,产生人体血压、脉搏参数,编写了相应程序,并通过WiFi模块以MQTT协议的方式发送至本系统的"乐为物联"物联网云平台接收端,实现血压和心率值的实时存储与显示等功能。系统可以通过本机液晶屏查看数据,也可以通过网页浏览或手机以微信公众号订阅等方式获取数据,方便数据分析、交流。
As to develop a kind of Internet of things based blood pressure wireless monitoring system, the hardware of this wireless digital sphygmomanometer system was designed and developed, and the blood pressure measurement signal was sampled by the pressure sensor MPX5050 GP and peripheral circuits. The signals used by oscillation wave method of two-way blood pressure measurement were calculated through STM32 F407 VGT6 MCU A/D conversion and the ratio algorithm, and the blood pressure and pulse parameters were generated and corresponding program was compiled, which were transmitted to the Internet of things cloud platform's receiving end called "LEWEI50" via WiFi module on the basis of MQTT protocol, achieving real-time record and display of the blood pressure and heart rate value.The system can check the data through the LCD screen, website or WeChat subscription of mobile phone and other ways to obtain data for convenient data analysis and exchange.
