人體健康參數(shù)監(jiān)測系統(tǒng)的設(shè)計
人體健康參數(shù)監(jiān)測系統(tǒng)設(shè)計 摘要 近年來,隨著人們生活水平的不斷提高,健康意識的逐漸增強,健康問題已經(jīng)成為人們關(guān)注的焦點,人體健康參數(shù)監(jiān)測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,中央控制單元發(fā)出監(jiān)測指令(不同的生命參數(shù)對應不同的指令),由數(shù)據(jù)采集單元控制傳感器開始對人體生理信號進行采集,采集到的模擬信號經(jīng)放大、濾波、陷波、整形等調(diào)理電路,傳輸至ADuC841單片機進行A/D采樣處理,能實時的對人體體溫、脈搏、心率、血壓和血氣等參數(shù)信息傳遞給中央控制單元ADuC7026,中央控制單元對監(jiān)測到的數(shù)據(jù)進行分析及實時顯示,同時存入數(shù)據(jù)庫供隨時回放,并通過串口與PC機通訊,將存儲資料進行打印分析。 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.
