文档介绍：人体健康参数监测系统设计
摘要
近年来,随着人们生活水平的不断提高,健康意识的逐渐增强,健康问题已经成为人们关注的焦点,人体健康参数监测仪器的研究也成为重要的研究课题。本系统主要由数据采集单元(ADuC841)、中央控制单元(ADuC7026)、显示单元等组成。系统工作时,中央控制单元发出监测指令(不同的生命参数对应不同的指令),由数据采集单元控制传感器开始对人体生理信号进行采集,采集到的模拟信号经放大、滤波、陷波、整形等调理电路,传输至ADuC841单片机进行A/D采样处理,能实时的对人体体温、脉搏、心率、血压和血气等参数信息传递给中央控制单元ADuC7026,中央控制单元对监测到的数据进行分析及实时显示,同时存入数据库供随时回放,并通过串口与PC机通讯,将存储资料进行打印分析。

Human health parameter monitoring system
ABSTRACT
In recent years, with the continuous improvement of living standards, health consciousness is gradually increased, health has e a focus of attention, the study of the health parameter monitoring instruments also e an important research topic. The system mainly consists of data acquisition unit, central control unit and display unit. During the operation, the central control issues the monitoring instruction, the unit the sensors start to collect physiological signals. After processed by the amplification, filtering, notching and shaping circuits, the signals are transferred to the microcontroller for further processing. The signals are sampled by the A/D converter, to real-time display human body temperature, pulse, heart rate, blood pressure and blood gas parameters such information to the central control unit ADuC7026, the central control is in charge of receiving, analyzing and displaying the data which is from the sensors, and storing the data in the database for playback at any time. It conmunicats with the PC through the serial port for priting of the stored data.
Key word:the health parameter monitoring instruments;data acquisition unit;central control unit;display unit;the serial port
