Problems solved by technology

However, it is not easy to obtain sleep data, and the workload of manual labeling is also very large.
Therefore, it is difficult to obtain enough training samples
In the case of limited training samples, it is difficult for the sleep stage classifier to have good universality, and the accuracy of sleep stage determination is difficult to be guaranteed.

Embodiment 1

[0035] Embodiment 1 of the present invention provides a method for determining a sleep stage, and the steps of the method can be as follows figure 2 shown, including:

[0036] Step 101. Determine a first ECG characteristic parameter of an ECG signal.

[0037] In this step, the first ECG characteristic parameter of the ECG signal within a specified time period may be determined. The first ECG characteristic parameter can be understood as, but not limited to, signals such as heart rate variability or heart rate.

[0038] The electrocardiographic signal may be the received electrocardiographic signal collected in advance, or the electrocardiographic signal collected in this step.

[0039] It should be noted that, in order to subsequently describe the sleep stage corresponding to the specified time period, the specified time period may be sequentially divided to obtain a plurality of time segments according to a duration not greater than a set time period. Specifically, the sp...

Embodiment 2

[0057] Embodiment 2 of the present invention provides a method for determining a sleep stage, and the schematic diagram of the steps of the method can be as follows image 3 shown, including:

[0058] Step 201, collect electrocardiographic signals, and determine heart rate variability.

[0059] In this step, ECG signals within a specified time period can be collected, and the heart rate variability rate after detrending analysis can be obtained according to the collected ECG signals, and information related to sleep time in the heart rate variability rate data can be eliminated to reduce subsequent According to the complexity of segmenting and matching with the set conditions according to the heart rate variability rate, the accuracy of segmenting and matching with the set conditions is improved, thereby improving the accuracy of determining the sleep stage.

[0060] Specifically, in this step, the R wave position of the ECG signal collected within a specified time period can...

Embodiment 3

[0081] Embodiment 3 of the present invention provides a sleep stage determination system, the structural diagram of the system can be as follows Figure 4 As shown, it includes a determination module 11 and an analysis module 12, wherein:

[0082] Determining module 11, for determining the first electrocardiographic characteristic parameter of the intracardiac signal of specified time period;

[0083] The analysis module 12 is used to determine whether the first electrocardiographic characteristic parameter meets the set condition in a time segment of the specified time period, and if it is determined that the first electrocardiographic characteristic parameter satisfies the set condition, determine the time The sleep stage corresponding to the segment is waking or rapid eye movement sleep (REM), otherwise, determine that the sleep stage corresponding to the time segment is not waking or REM; obtained by division.

[0084] The analysis module 12 is specifically used to deter...

Abstract

An embodiment of the invention provides a sleep stage determining method and a sleep stage determining system. The sleep stage determining method includes: determining a first electrocardio characteristic parameter of an electrocardio signal, and determining whether a sleeper is in a waking stage or an REM (rapid eye movements) sleep stage or not within a time segment by means of judging whether the first electrocardio characteristic parameter satisfies a characteristic of the waking stage or the REM sleep stage or not within the time segment. Determination of a macro sleep structure is achieved by means of distinguishing the waking stage, the REM sleep stage or other similar sleep stages. Sleep stage determination is achieved by means of rule judgment, and accordingly, accuracy of sleep stage determination is guaranteed. Moreover, a sleep stage classifier can be used cooperatively to achieve comprehensive judgment on the sleep stages and can be used for classifying other kinds of sleep stages into a light sleep stage and a deep sleep stage so as to achieve a micro sleep structure, and accordingly, accuracy of sleep stage judgment is further improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a sleep stage determination method and system. Background technique [0002] People spend nearly 1 / 3 of their life in sleep, and the quality of sleep is directly related to the memory, study, work, immunity and other aspects of the human body. With the development of the times, people's life rhythm is getting faster and faster, and the pressure is getting bigger and bigger. Many people have sleep problems, and sleep monitoring has emerged as the times require. [0003] In sleep monitoring, human sleep is usually described by a sequence of 6 stages, which usually include: [0004] 1. The waking stage can be recorded as waking. During this stage, the consciousness of the sleeper is awake. [0005] 2. The stage of falling asleep can be recorded as non-rapid eye movements (NREM)1. In NREM1, the sleeper's eyes are closed, but if awakened during this stage, the sleeper may feel th...
