具体实施方式Detailed ways
以下结合附图对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。The specific implementations of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.
图1是本发明实施例提供的一种鼾声检测装置的结构示意图。如图1所示，所述鼾声检测装置包括：光传递部件20，该光传递部件用于对发光源10所发射的光进行传输，其中所述光传递部件20包括振膜30以及拾音孔40，所述振膜30能够因通过所述拾音孔40进入的鼾声而震动，进而影响所述发光源所发射的光的强度。FIG. 1 is a schematic structural diagram of a snore sound detection device provided by an embodiment of the present invention. As shown in FIG. 1 , the snore detection device includes: a light transmission part 20 for transmitting the light emitted by the light source 10 , wherein the light transmission part 20 includes a diaphragm 30 and a sound pickup hole 40. The diaphragm 30 can vibrate due to the snoring sound entering through the sound pickup hole 40, thereby affecting the intensity of the light emitted by the light-emitting source.
上述方案中，对于发光源10可以是产生特定波长的发光二极管，例如产生610nm波长的发光二极管。振膜30为弹性材料，拾音孔40可以通过外界气流，但是外界光不能进入，振膜30能够因通过所述拾音孔40进入的鼾声而震动，进而影响所述发光源所发射的光的强度，当没有鼾声时，振膜30不会震动，不变形，进而不会影响所述发光源所发射的光的强度，当有鼾声通过时，如图2所示，振膜30震动，产生形变，进而影响所述发光源所发射的光的强度，则从所述光传递部件所输出的光的强度小于输入至所述光传递部件的光的强度。In the above solution, the light-emitting source 10 may be a light-emitting diode that generates a specific wavelength, for example, a light-emitting diode that generates a wavelength of 610 nm. The diaphragm 30 is an elastic material, and the sound pickup hole 40 can pass the external airflow, but the outside light cannot enter. The diaphragm 30 can vibrate due to the snoring sound entering through the sound pickup hole 40, thereby affecting the light emitted by the light-emitting source. When there is no snoring sound, the diaphragm 30 will not vibrate, not deform, and will not affect the intensity of the light emitted by the light-emitting source. When there is a snoring sound passing through, as shown in FIG. If the deformation is generated, which affects the intensity of the light emitted by the light-emitting source, the intensity of the light output from the light transmission part is smaller than the intensity of the light input to the light transmission part.
另外，为了近距离检测鼾声，所述鼾声检测装置的佩戴位置为尽量靠近面部的口鼻位置。In addition, in order to detect snoring sound at close range, the wearing position of the snoring sound detection device is the position of the mouth and nose as close to the face as possible.
通过本发明实施例提供的鼾声检测装置，利用光传递部件中的振膜能够因通过所述拾音孔进入的鼾声而震动，进而影响发光源所发射的光的强度，通过光的强度的变化来识别鼾声压力值，解决了现有技术中通过麦克风检测鼾声有电信号接触人体的安全隐患，以及通过气流管路检测鼾声存在压力衰减检测失灵的问题，通过本发明实施例中的光传输检测鼾声，既可以避免电信号接触人体，提高了安全性，又可以利用光传递速度快的优势，保证检测的准确性。With the snoring sound detection device provided by the embodiment of the present invention, the diaphragm in the light transmission component can vibrate due to the snoring sound entering through the sound pickup hole, thereby affecting the intensity of the light emitted by the light-emitting source. To identify the pressure value of snoring sound, it solves the potential safety hazard in the prior art that the electrical signal of snoring sound is detected by a microphone and contacts the human body, and the problem of pressure attenuation detection failure in detecting snoring sound through the airflow pipeline. Snoring can not only prevent electrical signals from contacting the human body, improve safety, but also take advantage of the fast transmission speed of light to ensure the accuracy of detection.
在本发明的一种实施方式中，图3示出了本发明实施例提供的一种鼾声检测装置的结构示意图。如图3所示，所述装置还包括：入光检测部件50，用于检测输入至所述光传递部件的光的强度；以及出光检测部件60，用于检测所述光传递部件所输出的光的强度。In an embodiment of the present invention, FIG. 3 shows a schematic structural diagram of a snore sound detection device provided by an embodiment of the present invention. As shown in FIG. 3 , the device further includes: an incoming light detection part 50 for detecting the intensity of light input to the light transmission part; and a light outgoing detection part 60 for detecting the light output from the light transmission part the intensity of light.
其中，所述入光检测部件50和出光检测部件60可以均为光敏三极管，另外，为了提高检测精度，所述入光检测部件50和出光检测部件60中还可以包括只能通过特定波长的干涉滤光片(图中未示)，例如，当发光源10为能够产生610nm波长的发光二极管时，则所述干涉滤光片只能通过610nm波长的光，减少干扰。Wherein, the incoming light detection part 50 and the light outgoing detection part 60 may both be phototransistors. In addition, in order to improve the detection accuracy, the incoming light detection part 50 and the light outgoing detection part 60 may also include interference that can only pass a specific wavelength. For example, when the light source 10 is a light emitting diode capable of generating a wavelength of 610 nm, the interference filter can only pass light with a wavelength of 610 nm to reduce interference.
在本发明的另一种实施方式中，经所述拾音孔40进入的鼾声能够垂直到达所述振膜30的表面。为了提高鼾声检测的准确性，如图4所示，在所述光传递部件20上设置两个拾音孔40，相对设置在所述光传递部件20上位于所述振膜30的两侧的位置。In another embodiment of the present invention, the snoring sound entering through the sound collecting hole 40 can reach the surface of the diaphragm 30 vertically. In order to improve the accuracy of snoring sound detection, as shown in FIG. 4 , two sound pickup holes 40 are provided on the light transmission part 20 , and two sound pickup holes 40 are arranged on the light transmission part 20 opposite to the two sides of the diaphragm 30 .

通过上述技术方案，利用通过拾音孔进入的鼾声对振膜的影响，从而影响所述发光源所发射的光的强度，通过检测输入至所述光传递部件的光的强度以及所述光传递部件所输出的光的强度来检测鼾声。由于本发明实施例利用光的传递，避免现有技术中利用电信号检测带来的安全隐患，以及避免了气流导管传输衰减的问题，提高了鼾声检测的安全性和准确性。Through the above technical solution, the influence of the snoring sound entering through the sound pickup hole on the diaphragm is used to influence the intensity of the light emitted by the light-emitting source. The intensity of the light output by the component is used to detect snoring. Because the embodiment of the present invention utilizes the transmission of light, it avoids the potential safety hazard caused by the use of electrical signal detection in the prior art, and avoids the problem of transmission attenuation of the airflow duct, thereby improving the safety and accuracy of snore detection.
相应的，图6是本发明实施例提供的一种鼾声检测系统的结构示意图。如图6所示，本发明实施例提供的系统包括上述图1-图5中任一附图所示的鼾声检测装置61，以及处理器62，其中，所述处理器62，用于根据输入至所述光传递部件的光的强度与所述光传递部件所输出的光的强度之差，确定待测鼾声压力值。Correspondingly, FIG. 6 is a schematic structural diagram of a snore sound detection system provided by an embodiment of the present invention. As shown in FIG. 6 , a system provided by an embodiment of the present invention includes the snore sound detection device 61 shown in any of the above-mentioned FIGS. 1 to 5 , and a processor 62 , wherein the processor 62 is configured to, according to the input The difference between the intensity of the light to the light transmission part and the intensity of the light output by the light transmission part determines the snore pressure value to be measured.
通过上述鼾声检测系统，在由鼾声检测装置得到的输入至所述光传递部件的光的强度与所述光传递部件所输出的光的强度之后，确定待测鼾声压力值。通过光的强度的变化来识别鼾声压力值，解决了现有技术中通过麦克风检测鼾声有电信号接触人体的安全隐患，以及通过气流管路检测鼾声存在压力衰减检测失灵的问题，通过本发明实施例中的光传输检测鼾声，既可以避免电信号接触人体，提高了安全性，又可以利用光传递速度快的优势，保证检测的准确性。With the above snore detection system, the snore pressure value to be measured is determined after the intensity of the light input to the light transmission part and the intensity of the light output from the light transmission part obtained by the snore detection device. The pressure value of snoring sound is identified by the change of light intensity, which solves the potential safety hazard in the prior art that the electrical signal of snoring sound is detected by a microphone and contacts the human body, and the problem of pressure attenuation detection failure in detecting snoring sound through the air flow pipeline is implemented by the present invention. The optical transmission in the example detects the snoring sound, which can not only prevent the electrical signal from contacting the human body, improve the safety, but also take advantage of the fast optical transmission speed to ensure the accuracy of the detection.
在本发明的一种实施方式中，为了保证光传递的稳定性，在根据输入至所述光传递部件的光的强度与所述光传递部件所输出的光的强度之差确定待测鼾声压力值之前，所述处理器还用于执行以下操作中的一者或多者：In an embodiment of the present invention, in order to ensure the stability of light transmission, the snore sound pressure to be measured is determined according to the difference between the intensity of the light input to the light transmission part and the intensity of the light output by the light transmission part value, the processor is further configured to perform one or more of the following operations:

例如，判断所述输入至所述光传递部件的光的强度是否在1s内稳定于所述入光强度预设范围，若稳定则进行确定待测鼾声压力值的处理，若不稳定，则报错。或者判断所述光传递部件所输出的光的强度是否在5s内稳定于出光强度预设范围，若稳定则进行确定待测鼾声压力值的处理，若不稳定，则报错，可结束检测，关闭发光源。或者上述1)和2)同时进行判断，当所述输入至所述光传递部件的光的强度和所述光传递部件所输出的光的强度均稳定时，则进行确定待测鼾声压力值的处理，若不稳定，则报错，可结束检测，关闭发光源。For example, it is judged whether the intensity of the light input to the light transmission component is stable within the preset range of the incident light intensity within 1s, and if it is stable, the process of determining the pressure value of the snoring sound to be measured is performed, and if it is not stable, an error is reported . Or determine whether the intensity of the light output by the light transmission component is stable within the preset range of light intensity within 5s, and if it is stable, the process of determining the snoring pressure value to be measured is performed. If it is unstable, an error is reported, the detection can be ended, and the light source. Or the above 1) and 2) are judged at the same time, when the intensity of the light input to the light transmission part and the intensity of the light output by the light transmission part are both stable, then determine the snoring sound pressure value to be measured.

The measured snore pressure values fluctuating within the range are marked and/or stored. Wherein, using the definition of snoring sound frequency in the prior art, the preset snoring sound frequency range can be set to 25 Hz to 300 Hz, and the pressure value of the snoring sound to be measured fluctuating within the preset snoring sound frequency range is marked and/or stored. .
