Human body sign monitoring method and device and intelligent monitoring pillow

The invention relates to a human body sign monitoring method and device and an intelligent monitoring pillow.The human body sign monitoring method comprises the steps that a first signal collected by a sensor is obtained at first, then filtering preprocessing is conducted on the first signal to obtain a second signal, and then a third signal is obtained according to the second signal, a time window and an iteration step length; and finally, acquiring signal characteristics of the third signal, determining whether a snore signal exists in the third signal according to the signal characteristics of the third signal, and determining a heart rate signal of the user according to the signal characteristics of the third signal. Therefore, according to the human body sign monitoring method, the signals collected by the sensor can be preprocessed, interference is removed, whether snore signals exist or not is determined according to the signal features of the preprocessed signals, the heart rate signals of the user ar
