【摘要】：现代社会老龄化速度逐步加快,亚健康和慢性病人群比例也逐步升高,这些都严重制约着和谐社会的实现和人们生活质量的提高;但是传统的医疗资源存在着城乡分布不均、优劣混杂等缺点,远不能满足人们对它日益增长的需求;因此为了实现对体温、血氧和脉搏健康参数的检测,本文设计了一种基于安卓智能手机音频口通信的多参数健康检测系统。本设计首先设计了3.7 V锂电池的USB充电电路和3 V的稳压电路来实现低功耗的Msp430单片机的供电,再利用单片机实现体温、血氧、脉搏参数的采集;其次将采集到的参数数据进行数据分析以确定参数数值是否在各参数正常检测范围内,是则直接将数据以特殊的调幅方式调制并按通信协议编码后通过手机音频口传送给手机端应用程序,否则便先驱动蜂鸣器警示后再将数据调制编码后传输给手机端;再次将体温、血氧、脉搏生理参数在手机音频口采样解调后按通信协议解码得到最终的生理参数值;最后在手机端应用程序上完成生理参数的显示、存储和查询功能,实现了多种参数的检测。通过测试发现本设计数据检测速度快、操作方便简单,具有一定的实用价值。
[Abstract]:The aging speed of modern society is speeding up, and the proportion of people with sub-health and chronic diseases is gradually rising, which seriously restricts the realization of a harmonious society and the improvement of people's quality of life; however, the traditional medical resources are unevenly distributed between urban and rural areas. The pros and cons are far from satisfying the growing demand for it; therefore, in order to detect the parameters of body temperature, blood oxygen and pulse health, A multi-parameter health detection system based on Android smart phone audio port communication is designed in this paper. In this design, the USB charging circuit of 3.7V lithium battery and the voltage stabilizing circuit of 3V are designed to realize the power supply of low-power Msp430 microcontroller, and then the collection of temperature, oxygen and pulse parameters is realized by the single-chip microcomputer. Secondly, the collected parameter data are analyzed to determine whether the parameter value is within the normal detection range of each parameter. It directly modulates the data in a special amplitude modulation mode and transmits the data to the application program of the mobile phone via the mobile phone audio port after coding according to the communication protocol, otherwise it drives the buzzer warning first and then transmits the data modulation and coding to the mobile phone end; The physiological parameters of body temperature, oxygen and pulse are sampled and demodulated in the audio port of the mobile phone again, and the final physiological parameters are decoded according to the communication protocol. Finally, the display, storage and query functions of the physiological parameters are completed on the application program of the mobile phone. The detection of various parameters is realized. Through the test, it is found that the design data detection speed is fast, the operation is convenient and simple, and has certain practical value.
