基于ARM嵌入式系统的便携式血压检测仪设计

Design of portable blood pressure measuring-apparatus based on ARM embedded system

为了实现血压检测便携性和实用性,文章采用了高性能的STM32F407芯片,实现了对血压检测过程的自动控制与调节。采用摩托罗拉公司MPX21000高精度压力传感器完成血压数据的采集。血压数据采集后可以实现自动显示以及储存,同时还进行了实时操作系统μC/OS-Ⅱ的植入,很大程度上提高了系统的稳定性和精度,且方便进行软件二次开发和升级。

In order to realize convenience and practicability blood pressure measuring, the paper used high-powered STM32F407 chip to automatic control and regulate blood pressure measuring process. It used MPX21000 high precision pressure sensor that designed by Motorola Inc to accomplish the blood pressure data collection. After the blood pressure data collection, it can realize automatic display and storage functions, at the same time, the detector also inserted μC/OS-Ⅱ real-time operating system, it improved the system’s stability and accuracy in a large part, and made a convenience to the system’s secondary development and upgrade.
