Abstract
The system uses dual MCU design to achieve the acquisition and transmission of pulse signal without affecting the users sleeping process. The pulse signal is collected by infrared pulse sensor, and is wireless transferred to the personal computer by JF24C after the process of amplification, baseline correction and so on. Then personal computer analyses the signal using the method of wavelet transform algorithm. With wavelet decomposition, pulse signal can be decomposed into different scales of wavelet coefficients and recomposed according to the low-frequency coefficient of the bottom and high-frequency coefficients of various layers. During the process of wave recomposition , the coefficients related to noise can be rejected while the valuable information in the pulse signal maintained, and all the processes achieve the restoration of pulse signal. What is more, after simulating the wavelet transform algorithm using MATLAB, the consequences of this simulation indicate that multiple interferences can be effectively suppressed while keeping the pulse signal undistorted and it sustains the relevant characteristics of pulse signal.
