1、 I 摘 要 本系统设计的是基于单片机控制的人体健康监测系统，本系统需要检测人体的三 个健康体征：心跳、体温、血压。由硬件和软件两部分组成。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。其次是温度检测，利用一线口温度传感器 DS18B20 进行温度检测，由于 该芯片采用单总线模式，在编程过程中严格按照该芯片的读写时序进行温度检测。再 次是血压检测，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显示出来。 另外还包括单片机电源电路、超限 报警电路、复位电路以及键盘电路。 本

3、 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 t

4、ransforms 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

5、 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 monol

6、ithic 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. This system research is advantageous to the development to the humanbody health examination need, has very many advantage to the dailylife improvement, has the very high practical value Key word Monolithic integrated circuit 8051; DS18B20; BP01; A/D transformation
