摘要随着社会的不断发展，医疗水平也在不断提高，人们也越来越关注自身的健康问题，人体健康监测系统由此得到发展。

本文 设计 的是 基 于 单片 机控制的人体健康监测系统，由硬件和软件两部分组成。本设计能够检测人体的三个健康体征：心跳、体温、血压。首先是心跳检测，利用压电传感器将检测到的心跳信号转换为电信号再通过集成运放转换成单片机可以接收的信号。然后是温度检测，利用温度传感器DS18B20进行温度检测，因为该芯片采用的是单总线模式，所以在编程过程中必须严格按照该芯片的读写时序来进行温度检测。接着是血压检测，利用压力传感器BP01将血压转换成为电信号，通过ADC0809模数转换器转化为数字信号通过单片机处理后呈现出来。另外本系统还包括了单片机电源电路、超限报警电路、复位电路以及键盘电路。76795

 Human health detection system

Abstract With the continuous development of society, the medical level is also increasing, people are increasingly concerned about their health problems, the human health monitoring system has been developed。

This system design is the human body health monitor system whichcontrols based on the monolithic integrated circuit, this system needshealthily to examine the human body three health body drafts:Palpitation, body temperature, blood pressure。 Are composed by the hardware and the software two parts。First is the palpitation examines, will examine the palpitation signalusing the piezoelectric pick-up to transform into the electricalsignal transports again through the integration puts transforms thesignal which the monolithic integrated circuit will be allowed toreceive。Next is the temperature examination, uses mouth temperature sensorDS18B20 to carry on the temperature examination, because this chipuses the single main line pattern, strictly carries on the temperatureexamination in the programming process according to this chipread-write succession。 Is the blood pressure examination once more, transforms into usingpressure transmitter BP01 the blood pressure the electrical signal,transforms through the ADC0809 modulus switch for the digital signaldemonstrates through monolithic integrated circuit processing。Moreover also includes the monolithic integrated circuit powercircuit, ultra limits the alarm circuit, repositions the electriccircuit as well as the keyboard electric circuit。

The papers concludes fourteen figures and twenty-two articles。
