In general, the number of people suffering from sleep disorders is gradually increasing due to complicated and irregular lifestyles, stress, and obesity due to an incorrect eating culture. Sleep disorders often involve symptoms such as snoring and sleep apnea. Especially, if snoring continues during sleep, the incidence of hypertension is twice as high and the incidence of myocardial infarction is higher than that of normal people without snoring. Snoring occurs when the throat passes through the air before it enters the airway and becomes narrow when the air cannot easily enter. This causes not only breathing difficulties during sleep, but also progresses to sleep disorders such as sleep apnea. Is likely to be. The snoring signal has a specific frequency band of about 800-1200 Hz. Conventionally, a pillow for preventing snoring is used to prevent the occurrence of snoring having the above characteristics, but malfunctions due to external noises are frequent, and when snoring strengths are different, the snoring is not accurately detected, and thus it is quickly used.

Referring to Figures 1 to 4 will be described the present invention.

First, the snoring signal detection unit 10 for inputting snoring and various noises and outputting a desired snoring signal includes a microphone 12 to which snoring and noise are input and a signal applied from the microphone 12 to a predetermined size. An amplifying unit 14 for amplifying a signal, an adder 16 for synthesizing two signals respectively applied from the two amplifying units 14, and a direct current for removing a direct current component of a signal applied from the adder 16. The signal removing unit 18 and the analog filter unit 20 for filtering only the signal applied from the DC signal removing unit 18 to pass a signal similar to the snoring signal, and the signal applied from the analog filter unit 20. Full-wave rectification circuit section 22 for rectifying the, and auto-gear authentication width section for adjusting the size of the signal to be a predetermined set size if the signal applied from the full-wave rectification circuit section 22 is too small or too large (auto a gain amplifier 24 and an A / D converter 26 for converting a signal applied from the auto gain authentication section 24 into a digital signal. Two microphones 12 are provided on both sides of a pillow (not shown) and have a frequency response of 20 to 20000 Hz with a sensitivity of -38 dB to input voice signals in all directions. The snoring signal and the noise signal, which are voice signals input through the microphone 12, are amplified by about 100 times through the amplifying unit 14 to have a constant magnitude (eg, -4V to + 4V), and the two amplifications. The signals amplified in section 14 are then summed in adder 16. The signal summed by the adder 16 removes the DC component through the DC signal removing unit 18. The signal applied from the DC signal removing unit 18 is filtered so that only the snoring signal and the similar noise signal pass through the analog filter unit 20 by passing only a signal in the 800 to 1200 kHz band corresponding to the snoring signal. The signal applied from the analog filter unit 20 is full-wave rectified by the full-wave rectifying circuit unit 22 so that only a signal of 0 to + 4V is applied to the control unit 30.

The signal passing through the full-wave rectifying circuit section 22 is applied to the auto-gear authentication section 24 to automatically adjust the amplitude of the signal applied from the full-wave rectifying circuit section 22. The signal applied from the auto gain authentication section 24 converts the analog signal into a digital signal (sampling at 0.82 msec interval ) in the A / D converter section 26. The A / D converter unit 26 of the snoring signal detection unit 10 applies a voice signal, which is a digital signal, to the control unit 30, and the control unit 30 is digitally applied from the A / D converter unit 26. The data corresponding to the snoring signal converted to the signal and similar noise signals are stored in the memory unit 60. In addition, if the magnitude of the signal applied from the A / D converter unit 26 is larger or smaller than the set size, the controller 30 controls the auto-gear authentication section 24 to adjust the signal to the set size. 30) always apply a certain amount of signal. Therefore, it can be used regardless of the small snoring of the person using the pillow for preventing snoring. The controller 30 analyzes the snoring signal, which is a voice signal stored in the memory unit 60, and a similar noise signal, and when the snoring signal is detected, operates the rotation motor driving unit 40.

The controller 30 stores the data corresponding to the snoring signal and the noise signal applied through the A / D converter unit 26 in the memory unit 60. The memory unit 60 stores data applied from the A / D converter unit 26 in sequence (S100) under the control of the controller 30, and the controller 30 stores the data in the memory unit 60. The selected data are sequentially selected in units of S (for example, 10) (S110), and the maximum value M, which is the highest value among the selected S (for example, 10) data, is obtained (S120). Select the highest data among the selected S data values to make the maximum value (M), and then replace the S data with the maximum value (M) with the maximum value (M) as the representative value. In order to store each of the maximum value (M) in order to store again in the memory (60) (S130). The controller 30 repeatedly executes a process of selecting a data value stored in the memory unit 60 in units of S and repeatedly calculating a maximum value. Then, the controller 30 uses all the maximum values M for each process as representative values. The S data values are replaced with the maximum value M and stored again.

There is a problem that the sampling rate must be very high due to the characteristics of the snoring signal and the noise signal, which are voice signals applied from the A / D converter unit 26 to the memory unit 60 under the control of the controller 30. In this way, the sampling problem can be solved by selecting and unifying the maximum value M as one representative value from any S unit. It is difficult to maintain the continuity of the data because the data stored in this way change at different levels for each S unit. Therefore, in the process of replacing all the S data with the maximum value M and storing the data in the memory unit 60 in order, a 64-point moving average is executed every time the data is replaced with the maximum value M (S140). Will be maintained. In addition, to increase the signal-noise ratio, the 64-point moving averaged data is squared. By squaring the 64-point moving averaged data, the final data L obtained by processing the snoring signal is obtained (S150). When the final data L is graphically illustrated, the snoring signal as shown in FIG. 3 may be illustrated.

As shown in FIG. 3, the snoring signal obtained by graphing the final data L is applied to the snoring signal specific threshold value K1 set in advance in the snoring-detection routine. (L) is compared with the threshold value K1. The number of final data L larger than the threshold value K1 is counted. By counting the final data L larger than the threshold value K1, a duration T1 in which the final data L is continuously larger than the threshold value K1 is obtained (S160). Therefore, the duration in which the final data L larger than the threshold value K1 is continuously input is set as 'T1', and when the value of the final data L becomes smaller than the threshold value K1, the first step is executed. do.

When the duration T1 satisfies the set time P1 by comparing the duration T1 with the set time P1 (for example, 0.6-2.5 seconds) initially set (S170), that is, 0.6 seconds. If 'T1' does not exist between 2.5 seconds, the first step is executed, and if 'T1' is present , the number of peaks R1 present during the duration T1 is counted ( S180). The maximum number of points R1 may be obtained by counting the portion of the maximum point by comparing the final data L stored in the memory unit 60 with the final data L before and after. Since the snoring signal has a maximum number of points (R1) different from the normal noise signal, the signal satisfying the previous step is calculated and used as the peak-point routine. By calculating the hourly rate of the maximum number of points (R1) and comparing it with the hourly rate of a certain set maximum number of points (R2) (S190), when 'R1' is greater than 'R2', it is recognized that one snoring signal is detected. (S200). If 'R1' is smaller than 'R2', the first step is executed.

Also, the time for detecting the second snoring signal is calculated from the time for detecting the first snoring signal. In other words, the second detection time is subtracted from the first detection time to calculate the idle time T2 from the first snoring signal to the next snoring signal.

The dwell time T2 should satisfy the dwell time arbitrarily set initially. If a signal satisfying the duration T1 of the snoring signal is detected during the idle time T2, it is determined that the snoring signal is not the first step. At this time, the first detected snoring signal is also ignored. When a signal satisfying the snoring duration T1 is detected after the designated time T2 after detecting the first snoring signal, the second snoring signal is recognized. This step is repeated until the third snoring signal is detected until it is recognized as snoring. At this time, a selection switch 70 for selecting the number of snoring signals is installed on the outside of the pillow, and when the first selection is made by using the selection switch 70, the snoring is detected once to operate the rotary motor driving unit 40. And, if the number 2 is selected to operate the rotary motor driving unit 40 after detecting twice, if the number 3 is selected to operate the rotating motor driving unit 40 after detecting three times.

In addition, when a signal is applied from the control unit 30 to the rotary motor 42 of the rotary motor driving unit 40, the rotation motor 42 is driven so that the posture deformation plate 46 operates to change the shape of the pillow. When the driving signal is applied from the controller 30, the rotary motor 42 rotates. The rotary shaft 42 is connected to the rotary motor 42 through a worm gear 41, and the cam shafts 44 are installed at opposite ends of the rotary shaft 43, respectively, in opposite directions. The posture deformation plate 46 is installed at the upper end of the camshaft 44, and the posture deformation plate 46 maintains an equilibrium state or inclines in one direction according to the rotation of the camshaft 44. Both sides of the rotating shaft 43 are mounted on the fixed shaft 45 so as to rotate, respectively, the posture deformation plate 46 is mounted on the fixed shaft 45 through the tension spring 47. Both sides of the posture deformation plate 46 are in close contact with the camshaft 44, respectively.

In addition, the control unit 30 is connected to the battery 52 of the power supply unit 50, the control unit 30 detects the amount of current charged in the battery 52 determines whether the set current amount is charged. When the amount of current charged in the battery 52 is low, the controller 30 operates the alarm sound generator 56 to generate an alarm sound. If the current level of the battery 52 continues to be low for a certain period of time because the alarm 52 is not charged or the power is not cut off after the alarm is generated, the battery cut-off unit 54 ), The battery 52 is cut off, and the battery 52 does not supply a current in a low state, thereby protecting the battery 52 by not completely discharging the battery 52.

As can be seen from the above description, the present invention calculates the final data L by processing the snoring signal and the noise signal which are voice signals detected from the microphone constituting the snoring signal detection unit, and calculating the final data L. Analyzes whether the duration T1 having a value greater than the threshold value K1 is greater than the set time P1, and if the duration T1 is greater than the set time P1, the maximum number of points that exist during the duration T1. (R1) is counted. When the maximum number of points R1 is greater than the set maximum number of points R2, it is determined as a snoring signal. When the snoring signal is detected the selected number of times, the control unit applies a driving signal to the rotating motor of the rotating motor driving unit so that the posture deformation plate of the pillow is inclined so as not to snor.
