Referring to fig. 1, fig. 1 is a side view of a cough type recognition device provided by the present invention.

As shown in fig. 1, the cough type identifying device 10 may include a fixing pin and button 101, a key switch 102, a network connection indicator 103, a signal acquisition indicator 104, a microphone sound receiving hole 105, a bone conduction sensor interface 106, a bone conduction sensor 107, a device body 108, and a connecting wire 109.

Specifically, the fixing pin and button 101, the key switch 102, the network connection indicator light 103, the signal acquisition indicator light 104, the microphone sound receiving hole 105 and the bone conduction sensor interface 106 may all be disposed on the housing of the device body 108.

Wherein, the fixing needle and the button 101 are arranged on the back of the shell of the device main body 108. The key switches 102 are disposed at the side of the housing of the device body 108. The network connection indicator light 103, the signal acquisition indicator light 104, the miniature microphone sound receiving hole 105 and the bone conduction sensor interface 106 are arranged on the top of the shell of the device body 108. The bone conduction sensor 107 is connected to the bone conduction sensor interface 106 by a connection line 109.

Specifically, when the target user uses the cough type recognition device 10, the cough type recognition device 10 can be fixed on the clothing of the target user through the fixing pin and the button 101, and the bone conduction sensor 107 is fixed on the body of the target user, so that the detection and carrying are convenient.

For example, but not limited to, the bone conduction sensor 107 is attached to the neck vocal cord occurrence of the target user by a disposable adhesive tape, and the cough type recognition device 10 is worn on the collar of the target user by fixing the needle and button 101. Referring specifically to fig. 3, fig. 3 is a schematic diagram illustrating a user wearing a cough type recognition device according to an exemplary embodiment of the present invention.

Specifically, bone conduction transducer 107 may acquire a first signal through contact with the body of the target user and micro microphone receiving aperture 105 may acquire a second signal through air. The acquisition periods of the first and second signals are the same.

The bone conduction sensor 107 transmits the first signal to the bone conduction sensor interface 106 through the connection line 109, and the bone conduction sensor interface 106 transmits the first signal to the device body 108. The miniature microphone sound-receiving aperture 105 transmits the second signal to the device body 108. The first signal and the second signal are subjected to extraction of signal features and identification of the cough type by a processing module inside the device main body 108, thereby confirming the cough type of the cough sound of the target user wearing the cough type identification device 10. The processing module inside the device main body 108 can refer to the cough type identification device shown in fig. 4, which will not be described herein.

Specifically, bone conduction means that sound waves are transmitted to the inner ear through the vibration of the skull, the jaw bone, and the like without passing through the outer ear and the middle ear, and without affecting others due to diffusion in the air. The technology utilizing the bone conduction principle is mainly embodied in bone conduction hearing aids, bone conduction microphones, bone conduction earphones, bone conduction mobile phones and the like.

The bone conduction transducer 107 may be collected and converted into an electrical signal using a slight vibration signal of the head and neck bone marrow that is caused by a person speaking (which vibration signal may be used to characterize the sound emitted by the user). Unlike a conventional microphone which collects or propagates an audio signal through air propagation, a bone conduction sensor is not affected by other sounds propagating through air, and a vibration signal of a target user contacting the bone conduction sensor can be collected or converted into sounds audible to the human ear and clearly propagated even in a very noisy environment. Therefore, the bone conduction transducer has good noise resistance and noise resistance.

However, since the frequency band of the signal that can be collected or transmitted by the existing bone conduction sensor is generally 0-2.4kHz, and the human cough sound is sometimes higher than the frequency band, the micro microphone sound collecting hole 105 is required to be matched with the collected cough audio signal, so as to collect the audio signal conforming to the human voice frequency band more comprehensively. The MEMS microphone, abbreviated as a micro microphone, may be formed by integrating various mechanical elements, sensors, and electronic circuits on a silicon chip by micro-electro-mechanical system (MEMS) process micro-processing technology, so that the micro microphone is more compact and smaller while improving audio quality.

After the start of the signal acquisition operation by the key switch 132, the signal acquisition indicator lamp 134 may be turned on.

The signal collection indicator lamp 134 may display the fifth state by performing the signal collection suspending operation through the key switch 132. Wherein the fourth state and the fifth state are different.

Please refer to fig. 4, fig. 4 is a schematic structural diagram of a cough type recognition apparatus according to the present invention, and the cough type recognition apparatus 40 may include a first acquisition module 401, a second acquisition module 402, a Digital Signal Processor (DSP) 403, a Micro Control Unit (MCU) 404, a communication module 405, and a power module 405.

Specifically, the first acquisition module 401 may acquire the first signal through contact with a target user wearing the cough type recognition device 40, and the second acquisition module 402 may acquire the second signal through an air medium.

As an alternative embodiment, the first acquisition module 401 may be, but is not limited to, a bone conduction sensor, a piezoelectric sensor, and a piezoresistive sensor. The second acquisition module 402 may be, but is not limited to, a micro-electro-mechanical system microphone, a moving coil microphone, a condenser microphone, or an electret condenser microphone.

For convenience to understand, the utility model discloses in use first collection module to explain for miniature microphone as bone conduction sensor, second collection module. The description of the bone conduction sensor and the micro microphone can refer to the description of fig. 1, and will not be repeated herein.

Specifically, the MCU404 is a control module, and is configured to control specific implementations of the first acquisition module 401, the second acquisition module 402, the DSP403, and the communication module 405.

Specifically, the MCU404 controls the first acquisition module 401 and the second acquisition module 402 to perform: acquiring a first signal and a second signal acquired when a user coughs; the first signal is a signal obtained by collecting other signals which are not sound and are generated when the user coughs in a contact mode, and the second signal is an audio signal obtained by collecting the sound generated when the user coughs.

The MCU404 controls the DSP403 to perform the following operations: obtaining a third signal according to the first signal and the second signal; determining a cough type of the user's cough from the third signal.

Specifically, although the first signal only belongs to the signal sent by the target user, the frequency band range of the first signal acquired by the contact type method is small, and the cough of the target user cannot be comprehensively represented. The second signal has a wide frequency band, but includes noise other than the voice of the target user. The utility model discloses combine first signal and second signal to obtain the third signal, get rid of environmental noise and other noises (like the other people's of non-target user speech sound, cough sound, the physical activity sound etc.) in the second signal, obtain the signal that only belongs to the target user and send, and the frequency band scope is comprehensive, can be used for the third signal of accurate sign target user's cough sound. The extraction of the first signal characteristics and the identification of the cough type are carried out on the third signal, so that not only can noise be filtered, but also the cough signals belonging to partial frequency bands of the target user can not be omitted, and the identification of the cough types such as dry cough, wet cough and the like is more accurate and comprehensive.

In particular, the first signal and the second signal each comprise a plurality of signal frames, each signal frame corresponding to a different acquisition period.

The acquisition periods of the first signal and the second signal may be identical, and the first signal may include the same number of signal frames as the second signal. Each signal frame of the first signal corresponds to a signal frame of the second signal one to one according to the acquisition period. For example, but not limiting of, the acquisition periods of the first signal frame of the first signal and the first signal frame of the second signal are the same.

The obtaining a third signal according to the first signal and the second signal includes:

if the energy of the first signal frame is larger than or equal to a preset energy threshold value, determining a second signal frame in the third signal as the first signal frame; the second signal frame and the first signal frame correspond to the same acquisition time period, and the first signal frame is any one of the first signals.

And if the energy of the first signal frame is smaller than the preset energy threshold, determining that the second signal frame is a third signal frame in the second signal, wherein the third signal frame and the first signal frame correspond to the same acquisition time period.

For ease of understanding, please refer to fig. 5. Fig. 5 is a schematic diagram illustrating obtaining a third signal according to the first signal and the second signal.

As shown in fig. 5, this embodiment includes a histogram of a first signal 51, a second signal 52, and a third signal 53, where the horizontal axis of the histogram represents signal frames and the vertical axis represents a corresponding signal spectrum for each signal frame. It should be noted that the signal exemplarily shown in fig. 5 only contains 10 signal frames, and in a specific implementation, the signal contained in the signal may be less than or greater than 10 signal frames, and the present invention does not limit the number of signal frames.

In the histogram of the second signal 52 and the third signal 53 shown in fig. 5, the different heights of the vertical axis signals are only used to indicate that the signals are different from each other. For example, but not limited to, the higher the height of the vertical axis signal corresponding to a signal frame is, the higher the loudness of the signal frame may be represented, and the higher the short-term energy of the signal frame may also be represented, which is not limited by the present invention. The color of the vertical axis signal is used to indicate whether the corresponding signal frame is an invalid signal frame or a valid signal frame. The color of the vertical axis signal is black to indicate that the signal frame is an effective signal frame, and the color of the vertical axis signal is gray to indicate that the signal frame is an ineffective signal frame.

It should be noted that, since the first signal 51 is a signal frame for excluding the non-target user voice in the second signal 52, the third signal 53 containing only the target user voice is obtained. In the process of acquiring the third signal, it is not necessary to consider the difference of signal characteristics such as loudness and short-time energy of each signal frame included in the first signal 51, and it is only necessary to distinguish whether each signal frame is invalid or valid. For ease of understanding, the histogram of the first signal 51 shown in fig. 5 has the same height and different color for all vertical axis signals. Wherein the color convention is consistent with the second signal 52 and the third signal 53 described above. In a specific implementation, however, the signal characteristics of the signal frames included in the first signal 51 may be different, and the present invention is not limited thereto.

The first signal frame of the first signal 51 is taken as the first signal frame to be processed currently. The second signal frame corresponding to the acquisition time of the first signal frame is a first signal frame of the third signal, and the third signal frame corresponding to the acquisition time of the first signal frame is a first signal frame of the second signal.

As shown in fig. 5, the color of the vertical axis signal of the first signal frame of the first signal 51 is gray, and the first signal frame is an invalid signal frame, that is, the energy of the first signal frame is less than the preset energy threshold. Thus, the second signal frame of the third signal is determined to be the first signal frame. That is, the first signal frame of the third signal 53 shown in fig. 5 is determined to be an invalid signal frame, and the color of the vertical axis signal is gray.

Then, as shown in fig. 5, the number of signal frames that have been processed in the first signal 51 is 1, which is smaller than the number 10 of all signal frames that the first signal 51 contains. It can be confirmed that the first signal frame is not the last signal frame of the first signal 51. The first signal frame is shifted backward by one frame length, i.e. the first signal frame is defined as the second signal frame of the first signal 51, and the processing and the judgment are continued.

The second signal frame corresponding to the acquisition time of the current first signal frame is the second signal frame of the third signal 53, and the third signal frame corresponding to the acquisition time of the current first signal frame is the second signal frame of the second signal 52.

Finally, as shown in fig. 5, if the color of the vertical axis signal of the redefined first signal frame (i.e. the second signal frame of the first signal 51) is black, the first signal frame is a valid signal frame, i.e. the energy of the first signal frame is equal to or greater than the preset energy threshold. Thus, the second signal frame of the third signal is determined to be the third signal frame of the second signal. That is, the vertical axis signal of the second signal frame of the third signal 53 shown in fig. 5 is determined to coincide with the vertical axis signal of the second signal frame of the second signal 52. By analogy, after all signal frames of the first signal 51 are traversed, a third signal 53 comprising 10 signal frames is obtained as shown in fig. 5.

After determining the third signal, in a possible implementation, the DSP may match the third signal with signals corresponding to each cough type stored in the DSP in advance to determine the cough type of the user cough, where the signals corresponding to each cough type are signals stored in the DSP after being processed in advance, and a processing procedure of processing the signals corresponding to each cough type is the same as a processing procedure of processing the signals corresponding to each cough type to obtain the third signal.

For example, if the matching degree of the third signal and the signal corresponding to the dry cough is higher than a preset threshold, determining that the cough type of the cough of the user is the dry cough; or, if the matching degree of the third signal and the signal corresponding to the wet cough is higher than the preset threshold, it is determined that the cough type of the user is the wet cough, and the cough type is not limited to this. The preset threshold may be set to 95%, 98%, etc. Any of the methods in the prior art may be adopted as the matching method for matching two signals (i.e., the method for matching the third signal with the signal corresponding to each cough type), and the embodiments of the present invention are not limited thereto.

Then, the DSP403 transmits the processed cough data (i.e., the cough type of the cough of the user described above) to the MCU 404. The MCU404 transmits the cough data to the communication module 405, and controls the communication module 405 to transmit the data result to the server. The server can send the cough data to the user terminal for display, and a target user can conveniently check the cough data through the user terminal.

As an optional implementation manner, the control module shown in fig. 4 is not limited to the MCU404, and in a specific implementation, the control module may also be a single chip or a Central Processing Unit (CPU). The utility model discloses do not limit to this.

In particular, a power module 406 for providing electrical energy to the cough type identifying means 40.

As an alternative implementation, the DSP403 may be a DSP of model TMS320LF2407APGEA, the MCU404 may be an MCU of model STM32F405RGT6TR, the communication module 405 may be implemented by an 88MW300 chip, and the power module 406 may be implemented by a low dropout regulator chip of model BL8568CB5ATR 33.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
