The invention discloses a sleep mild wake-up method based on a user sleep curve, and belongs to the technical field of
sleep monitoring, and the method comprises the steps: collecting a physiological
signal of a user, generating a sleep stage curve by using a pre-trained sleep stage model, and carrying out the parallel analysis of
heart rate variability and respiratory coordination to generate a
mood index curve; overlapping and fusing the two curves to form a sleep-
mood alignment
feature set; in a preset wake-up
time range, analyzing the sleep stage and psychological state of the user according to the
feature set, and dynamically determining an optimal wake-up starting opportunity; when the
clock arrives, an instruction is sent to the linkage
alarm clock, and sound, light and touch multi-mode stimulation is triggered in sequence in a cooperative mode; in the wake-up process, the sleep depth of the user is continuously monitored, if it is detected that the depth
recovery exceeds the
critical threshold value, the stimulation intensity is adaptively adjusted until the depth falls back, it is ensured that the user naturally wakes up under the condition that the discomfort is the lowest, and intelligent mild wake-up is achieved.
