基于STM32的心率检测仪设计与实现.docVIP

PAGE 24 内容摘要 现代科学的发展，导致越来越多人开始重视自己的身体健康，他们往往会想在能力之余使用健身运动等方式来锻炼自身。你会发现，在健身房，健身达人或者是教练都会叮嘱新手去关注自己的心率节奏。一般来说，人的激烈的锻炼会造成心脏血压的上升，心率变化从而加剧。而心率恰恰就作为人们运动的警戒和灯塔，运动状态下，心率的平稳状态、是否处于正常范围内都是健身人士应该注意的地方，不管你健身的目的是为了什么，而这更多的是与自身体重、体制等的相关。与此同时，心率的表现也能让人们能及时发现身体的异样。心率不定往往会造成。心脏、心血管等疾病。但往往是如此致命的病，检测其的方式就很简单。而心率检测的作用，就是作为一个实时监控并且在危急时刻能警报你的装置，由此可得出心率检测仪对人们的作用十分重要。 在这个系统设计上，采用了以STM32芯片中的F103系列芯片来作为总处理终端，在通过BUTTERWORTH滤波等之后将放大的心率信号进行除杂、去噪，也相对的对电路进行了优化。数据显示方面将用到一块OLED屏幕将个人的动态心率进行纪律以及同步在屏幕中显示出来，其显示的内容将包括心率的单独显示已经更显而易见的图标模式。利用心跳脉搏波形的特点以及心电图的基础将平均心率计算出来，从而展示出心率的“脉象图谱”。 关键词：心率检测 STM32 动态光谱 脉象图谱 Abstract For healthy, people often want to exercise themselves in ways such as fitness exercises in addition to their ability. Heart rate is exactly an indicator of exercise intensity, and its level directly affects the training effect of people, especially those who want to lose fat. At the same time, the performance of the heart rate can also allow people to detect the abnormal body in time. Irregular heart rates often result. Heart, cardiovascular and other diseases. But often such a deadly disease, the way to detect it is simple. The heart rate monitor is a device that can monitor you in real time and alert you in an emergency, so you can see that the heart rate monitor is very important for people. The heart rate detector is designed with STM32F103 as the core control terminal and signal acquisition and detection system, combined with dual-wavelength frequency division method and over sampler technology, which not only improves the signal resolution, improves the signal-to-noise ratio, but also greatly simplifies the circuit. Digital filtering and digital demodulation are used to separate the two - way signals. The data side will use an OLED screen to discipline and synchronize an individuals dynamic heart rate, which will include a separate display of the heart rate in an already more visible icon mode. The average heart rate is calculated according to the characteristics of the pulse wavefor
