基于MSP430的运动健康监测系统的设计
基于MSP430的运动健康监测系统的设计(论文14000字)
摘要：近年经济有了很大的进步，我国居民的生活水平与质量不断提高，身体肥胖与血脂高的人不断增多，使得出现了许多疾病，健康问题逐渐成为人们关注的焦点，锻炼身体成为现阶段人们最受用也是最快速有效的方法，那么运动健康监测就显得非常重要。本文将两者结合设计了一个便携式的计步与脉搏监测器。该系统采用MSP430单片机作为控制核心；选用加速度传感器ADXL345测量步数；采用脉搏传感器进行脉搏监测；所得结果通过LCD1602液晶显示；并通过蓝牙模块将结果传输给用户，以便进行实时运动健康监测。所设计的计步与脉搏监测器集成度高、体积小、功耗低、性能稳定，具有一定的实用价值。

Sports health monitoring system based on MSP430
Abstract: With the rapid development of economy, the living standards and quality of our residents have been continuously improved, while body fat and high blood fat people are increasing which can make the emergence of a number of diseases. So health problems have gradually become the focus of attention. It is very important to monitor sports and health because Physical exercise has become people's benefit and the most rapid and effective method. A portable meter step and pulse monitor system is designed in this paper. This system uses MSP430 single chip microcomputer as the control core, while uses acceleration sensor ADXL345to measure steps. The results obtained are displayed by the LCD1602 liquid crystal, and is transmitted to the user through the Bluetooth module. Real-time sports health monitoring is carried out in the system. The system has the characteristics of integrated level high, small size, low power, stable performance and practical value.
