【正文】 I 摘 要 本系統(tǒng)設(shè)計(jì)的是基于單片機(jī)控制的人體健康監(jiān)測系統(tǒng)，本系統(tǒng)需要檢測人體的三個(gè)健康體征：心跳、體溫、血壓。由硬件和軟件兩部分組成。首先是心跳檢測，利用壓電傳感器將檢測到的心跳信號(hào)轉(zhuǎn)換為電信號(hào)再通過集成運(yùn)放轉(zhuǎn)換成單片機(jī)可以接收的信號(hào)。其次是溫度檢測，利用一線口溫度傳感器 DS18B20 進(jìn)行溫度檢測，由于該芯片采用單總線模式，在編程過程中嚴(yán)格按照該芯片的讀寫時(shí)序進(jìn)行溫度檢測。再次是血壓檢測，利用壓力傳感器 BP01 將血壓轉(zhuǎn)換成為電信號(hào)，通過 ADC0809 模數(shù)轉(zhuǎn)換器轉(zhuǎn)化為數(shù)字信號(hào)通過單片機(jī)處理顯示出來。 另外還包括單片機(jī)電源電路、超限報(bào)警電路、復(fù)位電路以及鍵盤電路。 本系統(tǒng)的研究于開發(fā)有利于人體健康檢測的需要，對日常生活的改善有很多好處，具有很高的實(shí)用價(jià)值。 關(guān)鍵詞 單片機(jī) 8051； DS18B20； BP01； A/D 轉(zhuǎn)換 畢業(yè)設(shè)計(jì) (論文 ) Abstract II Abstract 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 posed by the hardware and the software two parts. First is the palpitation examines, will examine the palpitation signalusing the piezoelectric pickup 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 chipreadwrite 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 Key word Monolithic integrated circuit 8051。 DS18B20。 BP01。 A/D transformation 畢業(yè) (論 文 ) 目錄 III 目 錄 中文摘要及關(guān)鍵字 .............................................................................................................
