摘要
目前,由于中国的老龄化速度加快,中国老年人的数量越来越大,对于老年人来说,身体状况是第一大需要关心的问题,而目前最大的问题就是老年人不能实时地知晓自己的身体各项生理指标,主要是隔一段时间去医院体检一次,但是随着年龄的增长,一些疾病的发作是非常快的,对于某些突发的疾病,并不能做到一出现状况马上通知家人或者医院,以至于造成严重的后果。例如,老年人在运动时,由于运动量过大导致心率突变,接着导致心脏病突发等等。
针对以上情况,本文设计了一款便携式人体生理指标检测器,可以实时地检测人体的脉搏、体温,并对使用者的运动量进行大致估计,使使用者对自己的身体状况有大致的了解。
本设计分为两部分:、模块化设计。传感器采集数据,采集的数据送给单片机进行分析处理,通过软件编程设定各项指标的阈值,用字符型TC1604液晶显示所测的各项数值。并且可以制作PCB板使模块体积尽可能小,系统集成度高、工作稳定、电路简单、检测精度高、调试方便,非常具有实用价值。另一部分是通过SIM900A的GPRS模块进行通信,即传感器检测到人体参数异常,此时单片机控制SIM900A发送预置短信或者拨打预置电话,以便及时通知家人或者医院,对患者进行救治。实现了检测与处理的功能。

Title Portable physiological index detector

Abstract
Currently, due to China 's accelerated aging , the number of China 's old people ing more and more large , for the elderly, the needs of health care is the biggest problem , but now the most important problem is that the elderly can not know in real time the body's own physiological indicators ,usually once in a while to a medical hospital,But with the increasing of age,the onset of some diseases are very fast,for some diseases occured in a very short of time,we can not notice the family or the hospital timely,then there wil be a serious example,when the elder people doing some exercise,due to excessive movement mutations cause heart disease.
For the above situations,This paper designed a portable physiological index detector system,The detection system uses a hierarchical, modular sensors collect the dates,then microcontroller analysis the date,Set thresholds of the indicators by software programming,useing the LCD1604 to display the numbers,and we can use PCB to make the volume as small as is highly integrated, stable, simple circuit, high precision, easy debugging,the systemhas highly practical value,The other part is municate via GPRS module
