Further, the control module 30 is further specifically configured to position the human body according to the echo signal, and output a sleep monitoring result according to the target data after extracting corresponding target data from the echo signal according to a human body positioning result.
In this embodiment, please refer to fig. 5, when the millimeter wave radar module 20 in the monitoring device body 1 transmits a millimeter wave electromagnetic signal to the human body in the sleeping area, an echo signal reflected by the human body is received, the echo signal is complex data including amplitude information and phase information, not only including the radial distance and radial velocity information of the human body target, but also including rich micro-motion information of each part of the body, which can help the radar to distinguish the motion state and extract parameters of the human body target, so that if the sleep monitoring analysis is performed completely, the data amount to be processed is large, which results in too high power consumption and low efficiency of sleep monitoring, in this embodiment, the position of the human body is first located according to the echo signal, i.e. the distance between the human body and the monitoring device body 1, and the corresponding target data is extracted from the echo signal according to the obtained human body location result, and then the sleep monitoring characteristic analysis is performed, the processing efficiency is greatly improved by reducing the data processing amount, and the real-time sleep monitoring is more favorably realized.
In specific implementation, the control module 30 searches a maximum amplitude region in the echo signal, extracts target echo data corresponding to the maximum amplitude region, performs sleep feature analysis on the target echo data, and outputs a sleep monitoring result.
The sleep monitoring result comprises heart rate, and/or respiratory rate, and/or sleep state, and/or sleeping posture.
In this embodiment, control millimeter wave radar module 20 and detect echo signal when there is the human body in the sleep area, because millimeter wave radar signal is not good to human body penetrability, echo amplitude is very high, and can calculate the distance that the echo corresponds according to the echo time difference of receiving, consequently seek the maximum amplitude value in echo signal's the plural array, the distance that this maximum amplitude value corresponds is human position promptly to confirm the maximum amplitude region according to the width of the waveform that maximum amplitude value is located, the distance range that this maximum amplitude region corresponds promptly is human sleep area promptly, extract the target echo data that this maximum amplitude region corresponds in echo signal, through target echo data carries out sleep monitoring analysis, obtains corresponding sleep monitor result, realizes the monitoring to rhythm of the heart, breathing, sleep state and sleeping posture.
During specific implementation, a human body target tends to have a low motion speed, and a frequency spectrum part of the human body target and a ground clutter are distributed near a zero intermediate frequency, so that aliasing can be caused on a frequency domain, secondly, the human body motion contains abundant micro-motion information, a Doppler diffusion effect can occur, signal energy is dispersed, and the detection performance of the human body target is reduced.
When the separation of the doppler signals is performed, it may be performed in a time dimension or a two-dimensional combined dimension of a time-frequency dimension. During time domain separation, decomposing a signal into basis functions according to frequency bands by using the difference between main body motion and a micro motion form, and then reconstructing micro motion information, wherein the means for separating the signal from the time domain comprises wavelet decomposition, empirical mode decomposition and the like; when the time-frequency domain is separated, signals are converted to a time-frequency spectrum by using a time-frequency analysis method, and the signals are separated according to the difference of radial velocity of a main body movement and a micro-motion form along with the change of time, wherein common time-frequency analysis means comprise short-time Fourier transform, wavelet transform, Weiganan-Weill distribution and the like. The micro-motion information of the human body target obtained by separation can be used as characteristic vectors for motion state classification, namely different human body states are distinguished through the characteristic vectors, specifically, classification training can be carried out through setting a classifier, and common classifiers include KNN, SVM, artificial neural networks and the like.
Specifically, when an object moves towards or away from the radar, the frequency and the phase of the reflected chirp will change, and since the wavelength of a signal transmitted by the millimeter wave radar module 20 is in the millimeter level, any small change will cause a large phase change, when sleep monitoring is performed, the size of body movement can be obtained according to the size of mean square error after the mean square error calculation is performed on the phase in target echo data, and meanwhile, due to the movement of the chest of the human body, the target echo data extracted after the chirp is transmitted is phase-modulated, the modulation covers all components of the movement, including the movement caused by heartbeat and respiration, so that the heartbeat and respiration frequency values of the current target human body can be obtained by analyzing the target echo data, and then the sleep state can be judged. For example, when the human body is in a static state for more than one minute and is breathing steadily, the statistic is deep sleep when the human body is motionless, the statistic is shallow sleep when the human body is irregularly moved and the action amplitude is large (the mean square error is larger than 0.1), and the statistic is eye movement sleep when the human body is regularly moved and the action is small (the mean square error is smaller than 0.1), so that the sleep state monitoring is realized.
And because the radar detection areas of the human body under different sleeping postures (sleeping on back, sleeping on side and sleeping on lying prone), the maximum amplitude value of the extracted target echo data is different from the distance width corresponding to the maximum amplitude area, the sleeping posture is judged by presetting the width ranges corresponding to different sleeping postures, and when the distance width corresponding to the maximum amplitude area in the actually extracted target echo data falls into the corresponding width range, the current user can be judged to be sleeping on back, sleeping on side or sleeping on lying prone. Further, due to the fact that the micro-motion information in the target echo data is different in different sleep orientations in the same sleeping posture, for example, when the user sleeps on one side, the micro-motion size when the user faces the sleep monitoring device is larger than that when the user faces the sleep monitoring device on the back, the mean square error thresholds in different sleep orientations can be set, the detected mean square error is compared with the mean square error thresholds in different sleep orientations, the current sleep orientation can be further determined and distinguished, and accurate sleep posture judgment is achieved.
Further, a communication module 40, a power module 50, a microphone 60 and a speaker 70 are further arranged in the monitoring device body 1, the communication module 40, the power module 50, the microphone 60 and the speaker 70 are all connected with the control module 30, and the communication module 40 can adopt a bluetooth module, a WIFI module or a cellular network module to realize the communication connection with the mobile terminal for remote control; the power module 50 is used for supplying power to each functional module in the sleep monitoring device, and can be realized by dry batteries or rechargeable batteries and the like; the microphone 60 is configured to collect audio information, where the audio information may be voice information input by a user or background audio information in a current sleep environment, and the voice control or sleep quality judgment assistance is implemented through the audio information; the speaker 70 is used for outputting voice prompt information, so that a user can know the working state of the current sleep monitoring device conveniently.
