Embodiment Construction

[0055] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0056] A kind of real-time sleep monitoring record and analysis method of the present invention, such as figure 2 As shown, it includes two parts: recording and analysis. The recording part is responsible for recording and monitoring EEG signals, EMG signals and video signals, and the analysis part processes the collected signals in real time and obtains the sleep state.

[0057] The recording part includes a front-end recorder, an image sensor, a communication module, and a central processing unit. The front-end recorder includes a filter, a front-end amplifier, and a digital-to-analog converter, which are used to record EEG signals and EMG signals and filter out interference. The image sensor is used to record the video signal of the animal's movement behavior. The recorded data is aggregated, parsed and synchronized on th...

Abstract

The invention discloses a real-time sleep monitoring record and analysis method, which is a common method for studying the sleep state of humans or other animals in the field of biomedicine. It provides a system for real-time sleep monitoring combined with hardware and software. The hardware is responsible for collecting data. The software is responsible for classifying sleep data and achieving real-time effects. The analysis algorithm uses dimensioned parameters (key frequency band energy, effective value and motion data) and dimensionless parameters (normalized convolution calculation values) and uses the European Calculation of the distance and Mahalanobis distance to determine the classification of the sleep state increases the accuracy of the classification algorithm and completes the real-time capture of data from the device for the calibration of the sleep state.

Description

technical field [0001] The invention relates to the field of sleep monitoring and staging, in particular to a real-time sleep monitoring record and analysis method. Background technique [0002] The sleep state is an important state to distinguish when recording behavior or brain activity. In the sleep state analysis of mammals, the animal's behavior, EEG signal and EMG signal are mainly recorded, and then the three states of animal sleep are analyzed offline, namely the awake period, slow wave sleep period and rapid eye movement period. . In some studies, real-time feedback of changes in brain activity in various states, or brain activity after deprivation of a certain sleep state is required, and the mainstream data processing methods cannot meet the requirements of these studies. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the present invention proposes a real-time sleep monitoring recording and analysis method, which fe...
