摘要
随着生活水平的提高和健康意识的增强，血压和心率的监测成为人们关注自身健康的重要环节。对于中老年人而言，血压和心率的异常波动若不能及时监测和处理，可能会引发严重的健康问题，甚至危及生命。因此，研发一种能方便、准确监测血压和心率的设备十分必要。
本设计提出了一种基于 STM32F103C8T6 单片机的电子血压计。系统主要功能包括：通过血压检测模块检测当前用户的舒张压和收缩压；借助心率检测模块检测当前用户的心率；用户通过按键启动测量；当检测到心率或者血压不正常时，系统进行声光报警；通过 OLED 显示测量值；同时，系统通过存储模块存储检测的血压，可存储 20 组，用户可通过按键查看。
该电子血压计的作用在于，为人们提供了一种便捷、有效的血压和心率监测工具。通过及时监测和报警，能够帮助人们尽早发现健康隐患，便于及时采取措施，保障身体健康，提升生活质量。

Design of Electronic Blood Pressure Monitor Based on Single Chip Microcomputer
Abstract
With the improvement of living standards and the enhancement of health awareness, monitoring blood pressure and heart rate has become an important part of people’s attention to their own health. For middle-aged and elderly people, abnormal fluctuations in blood pressure and heart rate, if not monitored and treated in a timely manner, may lead to serious health problems and even endanger their lives. Therefore, it is necessary to develop a device that can conveniently and accurately monitor blood pressure and heart rate.
This design proposes an electronic blood pressure monitor based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the current user’s diastolic and systolic blood pressure through the blood pressure detection module; Using a heart rate detection module to measure the current user’s heart rate; The user initiates the measurement by pressing a button; When abnormal heart rate or blood pressure is detected, the system will sound and light an alarm; Display measurement values through OLED; At the same time, the system stores the detected blood pressure through a storage module, which can hold up to 20 sets, and users can view them by pressing a button.
The function of this electronic blood pressure monitor is to provide people with a convenient and effective tool for monitoring blood pressure and heart rate. By timely monitoring and alerting, it can help people detect health hazards as early as possible, facilitate timely measures, ensure physical health, and improve quality of life.
