Embodiment Construction

[0058] see figure 1 , a sleep stage monitoring method, comprising the following steps:

[0059] S101, acquire the tester's physical sign parameters, the physical sign parameters include body movement data, continuous breathing rate, continuous heart rate and heart rate variability;

[0060] S102, traversing the body motion data in the manner of a sliding time window to obtain a body motion data sequence reflecting a body motion frequency and a body motion duration in a region without body motion, and performing an opening operation and summing on the body motion data sequence by superimposing a morphological filter The signal obtained by the closing operation is used to obtain the body movement trend line;

[0061] S103. According to the fluctuation of the body motion trend line, extract the undetermined area in the body motion signal trend that meets the characteristics of the awakening period, and make a judgment based on the data changes of the continuous breathing rate an...

Abstract

The invention relates to a sleep staging monitoring method. The method carries out sleep staging monitoring by taking multi-dimensional vital sign parameters such as continuous heart rate, respiration rate and body movement as identification basis, and realizes accurate identification of an awakening period, a rapid eye movement period and a non-rapid eye movement period.

Description

technical field [0001] The invention relates to the field of sleep stage monitoring, in particular to a sleep stage monitoring method. Background technique [0002] Sleep is an important physiological activity that plays a key role in the physical and spiritual self-recovery of the human body. In recent years, with the acceleration of the pace of society, people's work and life pressures are increasing day by day, and the decline in sleep quality has become a problem faced by many people, seriously affecting their physical and mental health. [0003] Therefore, people pay more and more attention to the evaluation and analysis of sleep quality, and the basis and premise of sleep quality evaluation and analysis is to carry out sleep stage monitoring. The stages of sleep specifically include an awakening period, a rapid eye movement period, and a non-rapid eye movement period including a deep sleep period and a light sleep period. Under individualized differentiation, the sle...
