Embodiment approach

[0074] In an optional implementation manner, the two original sleep signals collected by the double-person sleep detection device can be obtained according to the preset signal duration that can be processed each time, and the time length collected by the double-person sleep detection device is obtained. Two original sleep signals of the above signal duration. For example, it can be set that the signal duration that can be processed each time is 1 minute, and the two-person sleep detection device collects a signal with a signal duration of 1 minute as the original sleep signal.

[0075] In another optional implementation manner, the two original sleep signals collected by the double-person sleep detection device can be obtained, and the number of cycles collected by the double-person sleep detection device can be obtained according to the preset signal cycle that can be processed each time. The two original sleep signals of the signal period. For example, the pre-set signal p...

Abstract

Embodiments of the present application provide a sleep signal processing method and device. Wherein, the method includes: acquiring two paths of original sleep signals collected by a double-person sleep detection device; extracting respective signal features of the two paths of original sleep signals; calculating the correlation coefficient of the two paths of original sleep signals; The respective signal characteristics of the sleep signals and the correlation coefficients of the two original sleep signals identify an effective signal corresponding to the state of the user in bed among the two original sleep signals. The embodiments of the present application aim to improve the accuracy of detection of the user's in-bed or out-of-bed state on the double mattress, laying a foundation for improving the accuracy of sleep detection.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular to a sleep signal processing method and device. Background technique [0002] With the progress of society and the improvement of living standards, people pay more and more attention to the quality of sleep, and the detection of sleep is very important. At present, there are many devices on the market that can detect sleep, such as wristbands, detection belts, mattresses, etc. These devices collect the user's sleep signals through acceleration sensors, piezoelectric sensors or other types of sensors, and then based on the collected Sleep Signal analyzes sleep quality. [0003] For single-person detection equipment, the accuracy of sleep quality analysis results can be guaranteed through specific algorithm processing. However, for a two-person detection device, since it includes two detection units, the situation is more complicated, and it is difficult to ensur...
