【正文】 基于人體脈搏信號(hào) 中文摘要 脈搏信號(hào)是一種較為常見的生物醫(yī)學(xué)信號(hào) ,是人體重要的動(dòng)力學(xué)信號(hào)之一 ,脈搏信號(hào)在相當(dāng)程度上可以反映人體心血管的生理狀態(tài)信息 ,它能反映人體心臟器官以及血液循環(huán)系統(tǒng)的生理情況變更 ,在臨床健康觀察和疾病診斷中位置非常的重要。因此脈搏信號(hào)的處理和分析在醫(yī)學(xué)界受到了廣泛的關(guān)注和重視。 具體研究工作為： （ 1） 通過采用一款 pulsesensor 基于光電反射式模擬傳感器用于測(cè)量脈搏、心率來檢 測(cè)人體模擬脈搏信號(hào)。 （ 3） 最后通過 matlab 對(duì)其進(jìn)行濾波處理消除噪聲干擾，得到正確脈搏信號(hào)。 關(guān)鍵詞： 人體脈搏信號(hào) 數(shù)字信號(hào)處理 濾波器 本科生畢業(yè)論文 數(shù)字信號(hào)處理算法研究 基于人體脈搏信號(hào) 3 Research on Digital Signal Processing Algorithm based on human pulse signal Abstract Pulse signal is a mon biomedical signal, is one of the important dynamic signals of the human body, the pulse signal to a certain extent, reflects the human cardiovascular physiological status information, it can reflect the human heart ans and blood circulation system physiological changes, It is very important in clinical health observation and disease diagnosis. Pulse signal processing and analysis in the medical world has been widely concerned and attention. With the development of electronic technology and puter technology, the human pulse signal into electrical signals for detection and analysis, to achieve intelligent pulse detection and analysis technology, biomedical engineering is the direction of research work: (1) to detect the pulse signal of human body by measuring the pulse and heart rate by using a pulsesensor based analog sensor. (2) and then through the Arduino microcontroller analog pulse signal into digital signal through the USB upload to the puter. (3) Finally, through matlab to filter it to eliminate noise interference, get the correct pulse signal. (4) after treatment found that the pulse signal can reflect the physiological characteristics of the human body.
