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.
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
