人體健康參數(shù)監(jiān)測(cè)系統(tǒng)的設(shè)計(jì)

人體健康參數(shù)監(jiān)測(cè)系統(tǒng)設(shè)計(jì) 摘要 近年來(lái)，隨著人們生活水平的不斷提高，健康意識(shí)的逐漸增強(qiáng)，健康問(wèn)題已經(jīng)成為人們關(guān)注的焦點(diǎn)，人體健康參數(shù)監(jiān)測(cè)儀器的研究也成為重要的研究課題。本系統(tǒng)主要由數(shù)據(jù)采集單元（ADuC841）、中央控制單元（ADuC7026）、顯示單元等組成。系統(tǒng)工作時(shí)，中央控制單元發(fā)出監(jiān)測(cè)指令（不同的生命參數(shù)對(duì)應(yīng)不同的指令），由數(shù)據(jù)采集單元控制傳感器開始對(duì)人體生理信號(hào)進(jìn)行采集，采集到的模擬信號(hào)經(jīng)放大、濾波、陷波、整形等調(diào)理電路，傳輸至ADuC841單片機(jī)進(jìn)行A/D采樣處理，能實(shí)時(shí)的對(duì)人體體溫、脈搏、心率、血壓和血?dú)獾葏?shù)信息傳遞給中央控制單元ADuC7026，中央控制單元對(duì)監(jiān)測(cè)到的數(shù)據(jù)進(jìn)行分析及實(shí)時(shí)顯示，同時(shí)存入數(shù)據(jù)庫(kù)供隨時(shí)回放，并通過(guò)串口與PC機(jī)通訊，將存儲(chǔ)資料進(jìn)行打印分析。 關(guān)鍵字：人體健康參數(shù)；數(shù)據(jù)采集單元；中央控制單元；顯示單元；串口通訊 Human health parameter monitoring system ABSTRACT In recent years, with the continuous improvement of living standards, health consciousness is gradually increased, health has become a focus of attention, the study of the health parameter monitoring instruments also become 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.
