Abstract

The invention provides a signal processing method and device. The method is applied to wearable equipment, wherein the wearable equipment is provided with a biosensor and a body movement detection device group; the method comprises the following steps: acquiring human physiological signals collected by the biosensor and dividing the human physiological signals into a plurality of signal frames, wherein each signal frame corresponds to a time range; for each signal frame, determining whether a wearing user is in a body movement state or not according to body movement signals collected by the body movement detection device group in the time range corresponding to the signal frame; and if not, storing the signal frames in a preset cache. Body movement is sensed through the body movement signals collected by the body movement detection device group, and the human physiological signals collected by the biosensor are filtered, so that the filtered human physiological signals all are signalsof the wearing user in a resting state, the stability and reliability of medical health monitoring and diagnosis of the wearable equipment are improved, and the false alarm rate is reduced.

Description

technical field [0001] The present application relates to signal processing, and in particular to a signal processing method and device. Background technique [0002] With the development of smart hardware, it is becoming more and more common to collect physiological signals of the human body through biosensors on wearable devices (such as bracelets, watches, etc.) for medical health monitoring and diagnosis. However, the physiological signals collected by biosensors are usually relatively weak, and are often interfered by various noises, such as motion noise introduced by human movement, contact noise between sensors and skin, etc. These interferences will directly lead to the decline of detection performance, and in severe cases will Detection fails because the signal is completely submerged in noise and cannot be reconstructed. Since the detection requirements of physiological signals are relatively high, any small error will bring a negative psychological burden to the ...
