Example two
As shown in fig. 3, this embodiment provides a snore stopping method, which includes the following steps:
s1: in the same time period, a snore signal is acquired through a sound acquisition module, and a pressure signal between the head and the pillow is acquired through a pressure detection module;
s2: detecting the peak energy density of the snore signal, calculating the average energy density of the snore signal, judging whether the peak energy density is larger than N times of the average energy density, and if so, executing a step S3;
s3: obtaining the respiratory information of the user according to the pressure signal, and obtaining the peak value information of the user according to the respiratory signal; identification of snore: the accurate identification of snore is a precondition for implementing snore stopping, and the embodiment combines the characteristic that the snore time phase information is synchronous with the breathing rate to accurately identify the snore, as shown in fig. 6.
S4: and judging whether the peak value information of the respiratory signal is matched with the peak value information of the snore signal, and if so, controlling the feedback module to work. The peak information is a time point corresponding to the mth peak, and the first determining step specifically includes: and judging whether the time point corresponding to the Mth wave peak of the respiratory signal is consistent with the time point corresponding to the Mth wave peak of the snore signal or not, and if so, controlling the feedback module to work.
Firstly, extracting snore signals, wherein a sound pickup embedded on a headband and positioned at the forehead is responsible for collecting snore information, the main frequency spectrum of the snore is distributed at 200-2000 Hz, so the sampling frequency is set to 4000Hz, and then energy integration is carried out, namely every 400 collected data Y are weighted to be used as an nth new data point S (n): s (n) ═ Σ y (i); therefore, the data is finally down-sampled to 10Hz, and then the snore energy envelope is obtained, so that the data size and time consumption in the identification operation can be reduced.
The extraction of the respiratory frequency comprises the steps of firstly carrying out superposition summation on data collected by the pressure sensor array and realizing smooth filtering to obtain a respiratory fluctuation signal when a human body sleeps, and carrying out differentiation and other processing on the signal to detect the peak position of the respiratory fluctuation signal.
Snore identification process: detecting the detected snore signals one by one, calculating the energy density P in a period of time before and after the Mth peak value, and comparing the energy density P with the average energy density P0, if the energy density P is more than N times, the detected snore signals are classified as snore candidates;
then, peak value detection is carried out on the processed respiration signal, the time point of the Mth peak value is calculated, whether the peak value corresponding to the Mth candidate snore exists is searched in a time interval (shown by a dotted line in figure 6) before and after the time point, if yes, the Mth candidate snore is determined as the real snore, otherwise, the Mth candidate snore is classified as the noise; and similarly, if the 5 respiratory signal peak values are continuously detected to correspond to the real snore, the person who falls asleep is considered to be snoring, the snore identification is successful, the snore stopping program is started, and otherwise, the detection is continued. When the time point is judged, a certain error is allowed to exist, namely the difference between the wave peak corresponding to the respiration and the wave peak corresponding to the snore is within T0, and the matching is successful.
Besides the direct comparison, whether the number of the wave peaks of the snore signal is the same as that of the wave peaks of the respiratory signal within a period of time can be detected to judge; when five peaks of the snore signal are detected in a period of time and five peaks of the respiration signal exist at the same time, the two are considered to be matched.
S5: continuously acquiring the pressure signal detected by the pressure detection module, judging whether the current sleeping posture of the user is the side sleeping posture according to the pressure signal, and controlling the feedback module to stop working if the current sleeping posture of the user is not the side sleeping posture. The work of the control feedback module is specifically to control the micro vibrator to continuously vibrate from weak to strong, and the micro vibrator is provided with a plurality of vibration intensity grades.
Because the plurality of pressure detection modules are arranged at the back part and two sides of the brain, when a user is in different sleeping postures, different pressure values can be generated at different pressure detection modules; for example, when the user lies on one side, the head is deviated to one side, at this time, the pressure value generated by the pressure detection module on the other side is relatively small, and the pressure value generated by the pressure detection module on the pressed side is relatively large; therefore, the sleeping posture of the user lying on the side can be judged. Similarly, when the user is in the supine sleeping position, the hindbrain is directly contacted with the pillow and the like, the pressure detection modules at the hindbrain part can generate larger pressure values, and the pressure values generated by the pressure detection modules at the two sides of the brain part are zero, so that the sleeping position of the user can be judged through the distribution of the pressure values.
The main reasons for judging the sleeping posture are as follows: in the supine position, the soft tissues and the tongue body of the upper airway and the pharyngeal portion are blocked by the factors such as gravity, muscle relaxation and the like, so that snore is easy to generate, and when the lateral position sleeping position is adopted, the upper airway is greatly reduced in narrow degree, so that the snoring and apnea conditions are obviously reduced and even disappear, and the lateral position sleeping position cannot be selected and controlled for a person who falls asleep. The snore stopping principle of the embodiment is based on that the sleeping posture of the sleeping person can be changed without arousing wakefulness, namely the supine position is changed into the lateral position, the upper airway stenosis degree is reduced, and the snore and the apnea symptoms are reduced or prevented. The biofeedback technique in this embodiment mainly achieves the purpose of stopping snoring of the user by applying appropriate stimulation through vibration feedback.
As shown in fig. 4 and 5, the present embodiment, based on the biofeedback technology, can accurately identify snore from a general sleeping environment by jointly analyzing the respiratory information detected by the membrane pressure sensor disposed on the headband and the snore information collected by the sound sensor disposed on the headband, so as to adopt the snore stopping stimulation, thereby changing the sleeping posture of the sleeping person to reduce snoring and apnea; and judging whether the sleeping posture of the person falling asleep is changed into a supine position or not after stimulation, and obtaining the signal distribution condition by analyzing the signal distribution condition of the film pressure sensor array arranged on the head band, and continuously applying vibration stimulation to the person falling asleep until the sleeping posture is changed or snore stops.
In this embodiment, after snore is accurately identified, a snore stopping program is started to apply stimulation with the time length of H1 to a snorer so as to adjust the sleeping posture; and if the sleeping posture is adjusted to be changed from the supine position to the lateral position, the change of the thin film pressure array signal distributed on the head ring is analyzed to obtain the change, if the change is detected, the stimulation of stopping snore is stopped, and if the change is detected, the existence of snore is also detected, the stimulation of stopping snore is also stopped, and if the change disappears, the stimulation intensity is increased to perform a new round of stimulation. In the embodiment, the snorer is stimulated by setting the vibration level, and the corresponding vibration level is recorded for reference of a user; therefore, the user can know the stimulation of the user under which vibration level to easily stop the snore, and then the user can directly set the device to the vibration level which is easier to achieve the snore stopping effect when the device is used next time, so that higher snore stopping efficiency is obtained.
The embodiment can firstly accurately identify the snore of a sleeping person, simultaneously stimulate the snoring person and force the sleeping posture of the sleeping person to be adjusted, whether the sleeping posture is adjusted in place is detected by a film pressure sensor arranged on a headband in real time, the stimulation intensity is from weak to strong, and the waking of the sleeping person is not influenced until the sleeping posture is adjusted or the snore disappears; the headband is comfortable to wear, and the user can watch the intuitive sleep quality analysis map after waking up, and helps the user to have higher sleep quality.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
