Embodiment Construction

[0032] The sleep monitoring system of the present invention is characterized in that it includes sleep monitoring based on wrist three-axis acceleration sensor signals and sleep monitoring based on sleep evaluation scale.

[0033] The three-axis acceleration sensor collects arm activity signals. And transfer data to smartphone or PC via bluetooth.

[0034] Smartphones use local sleep models to process acceleration signals to distinguish sleep levels and calculate sleep indicators. Proceed as follows:

[0035] A. Calculate the square root G of the sum of squares of the three-axis acceleration signals per minute. When the acceleration signal sampling rate is 20Hz, the number of data points per minute is 1200.

[0036] B. Calculate the eigenvalue STD of G, which is the standard deviation of the 1200 data points. MAX-MIN, which is the difference between the maximum value and the minimum value among the 1200 data points.

[0037] C. When STD>0.0225g and MAX-MIN>1g, mark this mi...

Abstract

The invention belongs to the field of wearable medical care, and relates to a sleep monitoring system and method. The hardware comprises a triaxiality acceleration sensor, a bluetooth module, and an intelligent mobile phone or a PC, wherein the triaxiality acceleration sensor collects an acceleration signal of a wrist of a human body; the bluetooth module is responsible for transmission of acceleration data to the intelligent mobile phone or the PC; APPs on the intelligent mobile phone and the PC can analyze the acceleration signal, can recognize a lucid interval and a sleep period, and calculate a sleep index. According to the sleep monitoring system and method disclosed by the invention, the rolling recognition rate can reach 98% through the acceleration signal, so that the sleep stage effect is improved; besides, only the acceleration signal is collected, so that the condition that power consumption is not too high is guaranteed.

Description

technical field [0001] The invention belongs to the field of wearable medical treatment, and relates to a sleep monitoring system and method. Background technique [0002] With the accelerated pace of life and increased work pressure, sleep disorders have become a major problem for modern people, especially in developed cities such as Beijing, Shanghai, Guangzhou, where almost 60% of people suffer from sleep disorders. There are many types of sleep disorders, which can be summarized into three categories: insomnia, insomnia, and insomnia. Sleep disorders will bring a lot of inconvenience to our lives, and will more easily lead to accelerated aging, decreased immunity, and the induction of cardiovascular and cerebrovascular diseases. It can be seen that maintaining a healthy sleep is very important. [0003] At present, the concept of preventive medicine is used to solve the problem of sleep disorders, that is, early detection and early treatment. The traditional sleep dis...
