Abstract
The present disclosure provides a photoelectric physiological signal acquiring and processing device including a light source, a photoelectric sensing device, an acquisition unit, an analog-to-digital device, and a microprocessing unit. The acquisition unit includes a current-to-voltage conversion module, a filtering device, and an amplification circuit. The photoelectric sensing device acquires a light transmitted through or reflected by the light source through the human physiological signal acquisition site, and converts it into a current signal. The current-to-voltage conversion module converts the current signal into a voltage signal, the filtering device and the amplification circuit process the voltage signal in sequence, the analog-to-digital device converts a processed voltage signal into a digital signal, and the physiological signal is obtained by the microprocessing unit.
