Description of the new model: [Technical field to which the new model belongs] This creation is about a kind of If acoustic sensing device 4, especially a kind of monitoring and recording the situation of sleeping and playing in a non-perceptive manner. After processing such as amplification, wave filtering, A / D conversion, etc., and program interpretation, eight to Behan output, it is refined to provide a snoring sensing device for overall sleep quality assessment. [Previous technology] According to the survey, "at least one fifth of the Chinese people have hiccups, and three-sevenths and seven dozens of Xuanxuan have more serious lesions." This has caused health problems and other problems. When possible, it occurs with the dangerous situation of apnea or cessation caused by exhalation, and even leads to hypoxia and interrupted sleep in the brain; after years and months, memory, attention, King of Kings 5 &, force and efficiency, and work quality Will gradually worsen, even dementia and other phenomena, spear brother Tsukasa, because sleep interruption will cause sleep, lack of sleep, there will be a tendency to drowsiness during the day. 'The proportion of car accidents or work accidents is far more than normal people- The issue of snoring cannot be ignored. Sleep related breathing disease (sleep related breathing dis〇rd_) Generally, multiple physiological monitors (Polisomnograph) are used for testing in hospitals, which is inconvenient and cannot be monitored for a long time. In view of the inconvenience of multiple physiological monitors at night, the author hopes Able to develop a relatively simple measuring instrument 'without losing accuracy' to monitor the snoring situation of the subject in a non-perceptive manner for a long-term monitoring, and inform the person who hit #f to determine if For medical reference, the overall design requirements are shown in the figure 'Divided into sensing methods & ^ month b, output tribute and commercialization for M268002 test i' so that people with snoring problems can do preliminary at home first For testing, if you need to go to the doctor I1 for detailed inspection, the preliminary test data can also be used as a reference for the doctor. The changes in the behavior of Daxuan during sleep can be observed by sound and gas flow in the nose. The signal acquisition method of the monitoring device is also divided into two aspects: the sound sensor and the gas monitoring. As shown in Figure 2, in AD [Yi Yiyi et al. 994] Use a nasal mask to introduce the air from the nostril into an air pressure sensor to measure the nasal gas / melon / trapping situation. The advantage of this method is that in addition to clearly recording the situation of beating Xuan, even the nitrogen in the breath, The proportion of gases such as oxygen can also be measured. The disadvantage is that the tester needs to wear a nasal mask during the measurement, which is inconvenient and affects sleep. Yu Xiwu and other scholars in 1995 and Alfaro and other scholars in 1999 used Yu Ke The wind harvest method measures the sound caused by Xuansheng.

Alfar〇等學者將麥克風放在離試驗者口部30cm處,Kim等學者 則以兩個麥克風’―個放在喉頭上,—個放在頭上同時進行監 測。麥克風收音的缺點為雜訊多,易受環境背景聲音影響,優點 為麥克風體積小可㈣隱藏、設備便宜、靈敏度高,不^試驗 者接觸口乎非察覺性監測的原則,因此本打軒監測裝置也將以 聲音感測方式進行設計研究。 以聲音感测方式作軒聲監測,除了來自外界的雜音會影響訊 號的可U外,4驗者躺在床上的位置、面部所朝方向等因素, 可能也都會所_於西元㈣年―做了有㈣聲評估 的實驗’將感測麥克風擺設於試驗者頭上恢^,實驗發現試 驗細與仰臥造成的誤差小於2分貝,用揚聲器模擬打軒音源 M268002 放在床的中央與兩側,誤差也在2分貝内。根據這樣的實驗結 果他〜為軒每音里判斷的公差應為±2分貝,且將麥克風擺設 在試驗者頭部上方是—個適當的位置。 搁取軒聲訊號,於西元1995年Smithson則使用一種「音量 累。十分配圖(cumulative distributi〇n 〇f 加 〇v⑽响 wund ki)」,來量化打軒的等、級。如圖三戶斤*,紀錄整晚房間内的音 置大小,並依音量大小與所佔時間比例繪圖,如此一來只須觀察 曲線與x_y軸所圍面積的大小,即可判斷打鮮情形的嚴重程度 這個方法可將整晚打鮮的情形簡化成_個數字表示,大幅節省資 料儲空間,亦不失參考價值與可信度。 、 以麥克風作為軒聲訊號的擷取容易受到雜訊以及背景雜音 的影響’在消除雜訊的手段,大致可分成從硬體的增加狀電路 低通濾、波器、軟體數位低㈣波器、以及利用特殊演算法...等方 理仍有不足 式。硬體低通濾、波器能去除高頻、低頻雜訊,只留下鮮聲頻帶内 的訊號’ Smith議於西元1995年之研究中表讀聲的最低頻率 略J於1 00Hz,可以作為聲音濃波的頻帶標準。雖然軒聲多半分 佈於100Hz以下的頻域’但一般日常的談話聲、笑聲。咳嗽聲 等也多包含有這個頻帶内的聲音,因此僅以低通濾波器方式做處 /於西元2_年Jane等學者使用⑵個聲音樣本訓練類神經 系統,藉由22項頻域與時域的聲音特徵輸入值,系統可以在離 線狀態下分析經由錄音設備所儲存的聲音資料,辨識㈣並摒除 M268002 其他雜音與雜訊。如圖四所示,為—充滿雜訊的訊號,經過處理 後仍能清楚分辨鼾聲與非鼾聲;如圖五所示,為顯示一突波聲音 出現,系統則將其視為如咳嗽等雜訊而不列入考慮。 根據文獻Smithson於西亓i qqs含4匕,· 6 士 70 1995年指出鼾聲主要集中在 麵2的低頻地帶’我們收集了日常生活常見的34種聲音,藉 由Matlab的Simulink模組將樣本聲音分別通過〇〜^、 ㈣销、*、心職的模擬帶通低通較器,以驗證文獻 的結果。34個樣本聲音分為軒聲、人類聲音、以及曰常動㈣ 生活器具三大類’觀察其在頻域上的分佈情形,紀錄得到如表丄 的聲音頻域分佈表,㈣“〇”代表 立 耳曰私含该頻帶的聲 _ 可發現3個樣本㈣大都包含在〇〜2_z 頻帶内,其他聲音分布頻域則較廣。因此本創作人首 收聲音的頻率著手’採用濾波曲線較為平滑的丨接 波器(如圖六所示),對外界接收聲 自動式低通滤 4 曰先行濾波,去除高頻訊號。Scholars such as Alfar0 placed the microphone 30cm away from the mouth of the test subject, while Kim and other scholars used two microphones—one on the throat and one on the head for monitoring. The disadvantage of the microphone radio is that it has a lot of noise and is easily affected by environmental background sounds. The advantages are that the microphone is small and can be hidden, the equipment is cheap, and the sensitivity is high. The tester's contact is based on the principle of non-perceptual monitoring. The device will also be designed for sound sensing. Xuan sound monitoring with sound sensing method, in addition to the noise from the outside will affect the signal U, 4 factors such as the position of the bed in the bed, the direction of the face, etc., may also be _ Yu Yuannian _ do In the experiment with snoring evaluation, the sensor microphone was placed on the subject's head. The experiment found that the error caused by the test and the supine was less than 2 decibels. The loudspeaker M268002 was simulated with a speaker and placed on the center and sides of the bed. The error Also within 2 decibels. Based on the results of such experiments, the tolerance judged in each tone of Xuan Xuan should be ± 2 dB, and the microphone should be placed at an appropriate position above the subject's head. Taking the Xuansheng signal, in 1995 AD Smithson used a "cumulative distributi. Ten distribution map (cumulative distributi0n 〇f plus 〇v⑽ wund ki)" to quantify the level and level of playing Xuan. As shown in the figure of three households *, record the sound setting in the room all night, and plot it according to the volume and the proportion of time occupied. In this way, you only need to observe the size of the area surrounded by the curve and the x_y axis to determine the freshness. This method can simplify the situation of refreshing the whole night to _ a number, which greatly saves data storage space without losing reference value and credibility. The use of microphones as Xuan sound signals is easy to be affected by noise and background noise. In the method of eliminating noise, it can be roughly divided into hardware low-pass filter, wave filter, and software digital low wave filter. , And the use of special algorithms ... and so on. The hardware low-pass filter and wave filter can remove high-frequency and low-frequency noise, leaving only the signal in the fresh sound frequency band. Smith suggested that the lowest frequency of table reading in the 1995 study was slightly lower than 100Hz, which can be used as Band standard for sound rich waves. Although Xuansheng is mostly distributed in the frequency domain below 100Hz ’, daily conversation and laughter are common. Cough sounds also include sounds in this frequency band, so they only use low-pass filters. In 2nd year AD, scholars such as Jane used a sound sample to train the neural system. With 22 frequency domains and time Domain voice characteristic input value, the system can analyze the sound data stored through the recording device in offline state, identify and eliminate other noise and noise of M268002. As shown in Figure 4, it is a noise-filled signal that can clearly distinguish between snoring and non-snoring after processing; as shown in Figure 5, in order to show the emergence of a sudden sound, the system considers it as a cough and other noise. Information without consideration. According to the literature Smithson Yu Xiqin qqs containing 4 daggers, 6 shi 70 In 1995, it was pointed out that the snoring was mainly concentrated in the low frequency zone of face 2. 'We collected 34 kinds of sounds common in daily life, and sampled the sounds through Matlab's Simulink module Pass the analog band-pass low-pass comparators of 0 ~ ^, ㈣ pin, *, and heart to verify the results of the literature. The 34 sample sounds are divided into three categories: Xuan sound, human sound, and daily life. Observe the distribution in the frequency domain. The record can be obtained from the audio-frequency distribution table shown in Table ㈣, where “〇” stands for It is said that most of the three samples are contained in the 0 ~ 2_z frequency band, while other sounds have a wider frequency domain. Therefore, the author started with the frequency of the first received sound 'using a smoother filter (as shown in Figure 6) to automatically receive low-pass filtering of externally received sound. This means that high-frequency signals are removed.

At the end of the sound from the fresh sound, you can find that the sound of the snoring is very regular: heavy Repeated. Please refer to FIG. 9 again, which is a more careful observation of the time and interval of the continuous maintenance of four or two times. To know the characteristics of U and interval between the snoring of the positive peak, You can use this feature to distinguish the recorded 簦 ^ ㈣ Zhuo Yue 5fl bluffs belong to snoring or non-snoring. If a sound signal is maintained for a period of time corresponding to the characteristics of the snoring car, and after a period of time, a sound that meets the characteristics of the snoring length is generated, and the length of the interval must also be consistent. If the sound characteristics, Jiang 5 纟 can distinguish far sounds as Xuan sound instead of ordinary noise, and the counter will start counting. Lee 1 uses the same idea, whether the subject is strung, and there is sleep apnea (〇SAS) produced ", " Wang " strange sounds may also be measured. However, in other daily life, he has not had the opportunity to present the above interval pattern. Therefore, another rule can be added to 12 M268002, that is, this interval pattern must occur twice in a row, if the mouth occurs-times The calculation will not be included until the second consecutive occurrence, and the first uncalculated snoring will be corrected (see Figure + 如图 No), so the chance of misjudgment will be greatly reduced. Please refer to Figure 11, which is a flowchart of the design concept of the above-mentioned Xuanyuan 4-sensor sensing device. It first uses a sound sensor to convert a sound wave signal into a voltage signal, and amplifies the signal through an audio amplifier. Signal for subsequent processing, and then enter the cut-off frequency of 2 'low-pass low-pass filter, and then through the A / D conversion system ... analog digital conversion' After the conversion is completed, the snoring identification software system 0 will perform Xuansheng Interval mode identification, the number of times of identification and display interface 43 are output; the 鼾 sound signal is amplified and filtered and input to pic single chip 4 for A / D conversion system 41 and stored in the computer. Make the waveform shown in Figure 12. Among them, the characteristic of the acoustic wave signal is that it will oscillate up and down according to a voltage level, but this signal form is not easy to handle. Therefore, the first step is to zero the voltage level in a programmatic manner. The method used is In order to calculate the a / d value of 10 strokes ~ average person, you can get the centerline of up and down oscillations, as shown in Figure 13, and then subtract the newly entered value from the centerline to get the accuracy shown in Figure 14. The waveform after the bit returns to zero, the culling frequency at this time is 2_Hz. Because the signal is oscillating up and down, but the downward data points are not helpful for the snoring judgment, so the method of finding the regional maximum value is used to remove unnecessary signals, that is, a maximum value is compared for each data point To represent these 10 points, the downward points can be removed. The waveform in Figure 14 is simplified as shown in Figure 15. At this time, the operating frequency is 200Hz, and the volume of chirping sound that plays 13 M268002 is about 75. In decibels, the maximum voltage caused by the snoring sound is 300mV, while the silent voltage is 75mV. The difference between the two is only 225mV. If the pitch of the snoring sound is even smaller, it may cause difficulty in judgment, so use 丨 〇 to do — The sub-summary is a method similar to the integral to strengthen the energy of the signal and widen the gap between the sound and the sound 'to facilitate judgment (as shown in Figure 16). However, its waveform still has excessive fluctuations, so it is smoothed with a 5-point average (see Figure 17). When the signal becomes as shown in Figure 17, the beeping sound will change from a complex up and down line to a smooth continuous increasing and decreasing signal. At this time, the program generates 20 data points per second. G2 seconds) are both increasing time points tl, indicating the beginning of ㈣; continuous 5 "material points (about 0.2 seconds) are decreasing time points are t2, indicating the end of Xuansheng; the difference between ^ Magic 2 is Xuan The duration of the sound; her next consecutive 5 asset-side time points are t3, t2 and t3 # Τ9 ρ & —— -◊ 差 丁 2 is the interval between the two sounds (as shown in Figure 18) . In this way, you can identify the two snoring durations D1 and snoring interval T2 required by the software system 42. After the calculation method of the snoring percentage and interval time is determined, we observe four The testees have continuous M, we can have a small chance, to determine shame a… go wrong to pass the time characteristics of the largest and most ambiguous—the second complete sound of the two. The other ten shows that four subjects, and then go * The duration of snoring sounds between 0 and 19 and 0.5 and 2.0 seconds each, ϋ, but never Most of the cases that fall from 1 to 2.0 seconds account for all 1.7% of the total amount.) 7 / ❶, we do not include this block difference in the calculation, so the meaning is 0.5 ~ 20. Evening „v v ear hold, time interval. However, the interval time between the most of them is between 1.6 ~ 3.6 M268002 seconds. Outside this interval, only 3% of the i is considered as an error. Xuansheng is defined as a "soundless situation with Ik with 1.6 ~ 3.6 seconds" and must be continued on a regular basis. In addition, the actual test line is divided into two stages. The first stage is first in the laboratory. The main purpose of using the recorded ㈣ test is to test the recognition rate of different test subjects by the Xuansheng monitoring device under a controlled environment; the field test is performed in the second stage, the main purpose is to test in the actual sleeping environment. Affected by factors including environmental noise, and other people who turn around, and other factors, Benxuan Sound monitors the Xuansheng recognition rate of the set-the test equipment layout of the Zhongyi and Nasal sound recognition test is shown in Figure 21. The microphone 5 and the sensor 6 are spaced 5Gem apart and placed with a decibel meter 7. The reason for putting the scallop 7 is that the volume range of the general Xuan sound is between 60 and 90 decibels, so it must also be at this time during playback. Ligu m, the right maximum snoring sound is more than 9 () dB : The volume caused by the sound is not counted, the experiment is not counted, and the experiment is performed again after the tone is small. The experimental results are shown in Table 2. There are four groups of materials numbered from A to D. Three tests were performed, and the value of _read divided by the actual number of times was defined as: the second rate. The average success rate of the test results was as low as 74%.毅… ^ 's perseverance and reproducibility m through μ identification software system ~ 卩 can effectively and accurately determine whether _ = The results obtained are more reliable and more basis.
