The invention relates to the technical field of medical monitoring, in particular to a unilateral chewing monitoring device and a monitoring method.

When eating food, the chewing muscles on the left and right sides should be chewed evenly, so that the gums on both sides can be evenly stimulated by the function, which is beneficial to the normal development of the teeth, jaws and corresponding muscles. If you chew unilaterally for a long time, you will develop muscles on one side and muscle atrophy on the other side.

FIG. 1 is a schematic diagram of a connection structure of a unilateral chewing monitoring device 100 according to an embodiment of the present application, which includes a first transceiver 110, a second transceiver 120, and a processor 130.

The first transceiver 110 is configured to transmit at least one wireless signal to the left chewing muscle within a period of time, receive at least one left reflected wave reflected by the left chewing muscle, and send the received left reflected wave to the processor 130. In a possible implementation manner, the first transceiver 110 is, for example, a wireless device. The wireless device transmits and receives a fixed-frequency wireless signal to the left chewing muscle at a certain time interval t, that is, the left reflected wave. Of course, those skilled in the art should understand that this is only an example and should not be construed as limiting the embodiments of the present application.

The second transceiver 120 is configured to transmit at least one wireless signal to the right chewing muscle during this period, and receive at least one right reflected wave reflected by the right chewing muscle, and send the received right reflected wave to the processor 130. In a possible implementation manner, the second transceiver 120 is, for example, a wireless device. The wireless device transmits and receives a fixed-frequency wireless signal to the right chewing muscle at a certain time interval t, that is, the right reflected wave. Of course, those skilled in the art should understand that this is only an example and should not be construed as limiting the embodiments of the present application.

The processor 130 is configured to obtain a left reflection wave sent by the first transceiver 110 during the period, obtain a left spectrum width value according to the left reflection wave, and obtain a right reflection wave sent by the second transceiver 120 during the period, according to the right The reflected wave acquires the right spectrum width value; and, at least according to the left spectrum width value and the right spectrum width value, determines whether it is a unilateral chewing during this period.

The inventor of the present application found that when a user chews with the left chewing muscle, the left chewing muscle's action amplitude is greater than the right chewing muscle's action amplitude, resulting in the left side reflection wave's spectrum width value H _{left being} greater than the right side reflection wave's spectrum width value H. _right ; When the user chews with the right chewing muscle, the action amplitude of the right chewing muscle is greater than that of the left chewing muscle, causing the right width of the reflected wave ’s spectrum H _{right to be} greater than the left width of the reflected wave ’s spectrum H _left ; similarly, When the user chews with the left and right chewing muscles, the left chewing muscle's action amplitude is equal to or almost equal to the right chewing muscle's action amplitude, resulting in the left side reflection wave's spectral width value H _left is equal to or almost equal to the right side reflection wave's spectral width value H. _right . Therefore, according to the magnitude relationship between the left-side reflected wave spectral width value H _left and the right-side reflected wave spectral width value H _right , it can be determined as left chewing or right chewing, or non-unilateral chewing or bilateral chewing.

Specifically, the processor 130 determines that the left-side chewing is based on that the left-side reflected wave ’s spectral width value H _{left is} greater than the right-side reflected wave ’s spectral width value H _right ; or that the right-side reflected wave ’s spectral width value H _{right is} greater than the left-side reflected wave ’s spectrum The width value H _{left is} determined to be right chewing; or, based on the spectral width value H _{left of the} left reflected wave is equal to or almost equal to the spectral width value H _{right of the} right reflected wave, it is judged to be bilateral chewing or non-unilateral chewing.

Figure 2 shows the spectrum curve of the left reflection wave and the spectrum curve of the right reflection wave, where the abscissa X is the frequency spectrum, the ordinate Y is the power spectral density, curve 21 is the spectrum curve of the left reflection wave, and curve 22 is the right The spectral curve of the reflected wave. It can be seen that the spectrum width value H _{left of the} curve 21 is greater than the spectrum width value H _{right of the} curve 22, then the schematic diagram of the curve shows that the user chews on one side and chews on the left side.

In this embodiment, the spectral width value of the left reflected wave and the spectral width value of the right reflected wave respectively reflect the left chewing condition and the right chewing condition. Therefore, according to the spectral width value of the left reflected wave and the spectral width value of the right reflected wave, , You can determine whether it is unilateral chewing.

In a possible implementation manner, the processor 130 obtains the left spectrum width value H _left according to the left reflected wave, and obtains the right spectrum width value H _right according to the right reflected wave; and the left spectrum width value H _left and the right spectrum width value The difference between H _right and a spectrum width threshold H _th is compared. When the absolute value of the difference between the left spectrum width value H _left and the right spectrum width value H _right is greater than or equal to the spectrum width threshold H _th (that is, H _left -H _right ｜ H _th ), it is determined to be unilateral chewing, and it is determined that the spectrum width value is greater than the chewing side; otherwise, it may be judged to be non-unilateral chewing. The spectrum width threshold H _th can be set according to circumstances.

In a possible implementation manner, the processor 130 obtains the chewing duration of unilateral chewing in multiple periods, obtains the cumulative duration of left chewing and the cumulative duration of right chewing, and obtains the cumulative duration of left chewing and right chewing. The difference of the cumulative duration of at least is based on at least the absolute value of the difference and the threshold of the duration difference to determine whether it is unilateral chewing during these periods. The duration difference threshold can be set according to the situation.

Specifically, the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing is greater than or equal to the threshold value of the difference in length, and it is determined as unilateral chewing. For the case of unilateral chewing, when the cumulative time of left chewing grows The cumulative duration of chewing on the right side is determined as left chewing; when the cumulative duration of left chewing is less than the cumulative length of right chewing, it is judged as right chewing. If the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the threshold difference, it is determined as bilateral chewing.

For example, for n chewing periods (n is a natural number), paragraphs 1, 2, 3, ..., n, respectively, obtain the chewing duration of each chewing period, and accumulate n chewing durations to accumulate. Duration T. Then obtain the cumulative duration T _{left of the left} chewing and the cumulative duration T _{right of the right} chewing during these n chewing periods, and obtain the difference between the cumulative duration T _{left of the left} chewing and the cumulative duration T _right of the right chewing. The absolute value of the difference is compared with the duration difference threshold T _th . When the absolute value of the difference between the cumulative duration T _{left of the left} chewing and the cumulative duration T _right of the right chewing is greater than or equal to the duration difference threshold At T _th (that is, T _left -T _right ｜ T _th ), it is judged to be unilateral chewing during these n periods, and it is judged that the accumulated time is the chewing side; otherwise, it is judged to be non-unilateral chewing. The method of recording the duration is, for example, calculating the chewing duration based on the start chewing time and the end chewing time. Of course, those skilled in the art may also use other methods to calculate the chewing duration, which is only used as an example here and should not be construed as a limitation on the protection scope of the present application.

The processor 130 may be provided in a wearable device, such as smart glasses, headphones, and the like. The processor 130 may communicate with the first transceiver 110 and the second transceiver 120 by means of Bluetooth, infrared, or the like. Of course, those skilled in the art should understand that this is only used as an example and should not be understood as a limitation on this application. Other ways of communicating with each other are also included in the protection scope of this application.

In this embodiment, if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than the duration difference threshold, it means that the user chews on one side for a long time. Thereby, it is possible to automatically monitor whether unilateral chewing is performed.

FIG. 3 is a schematic diagram of a connection structure of a monitoring device 300 according to another embodiment of the present application. The monitoring device 300 may further include: a prompter 340 for performing unilateral chewing according to the result of the processor 130 determining that it is unilateral chewing. prompt.

The processor 130 determines that it is unilateral chewing, and sends a trigger signal for unilateral chewing to the prompter 340, and the prompter 340 performs unilateral chewing prompt according to the trigger signal. For example, the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing is greater than the threshold difference, and the cumulative length of the left chewing is greater than the cumulative time of the right chewing, indicating that the left chewing is most of the time , You can be prompted to chew on the left side for a long time, or prompt the user to chew on the right side, or prompt the user to accumulate the left side and the right side for the user's reference to adjust the chewing side. Similarly, a unilateral chewing prompt can be provided for the case where the user uses the right chewing.

In a possible implementation manner, the prompter 340 is one, that is, the processor 130 sends a trigger signal for one-sided chewing to the prompter 340, and the prompter 340 provides a prompt according to the trigger signal, so that the user can know that he has used it for a long time. Chew on one side and adjust the chewing side accordingly.

In another possible implementation manner, the prompter 340 may include a left-side prompter and a right-side prompter. For a case where the left-side chewing is determined, the processor 130 may send a trigger signal of one-sided chewing to the left-side prompter. The trigger signal provides a reminder so that the user knows that he used the left side for chewing for a long time, and accordingly adjusted to use the right side for chewing. Similarly, for the case where the right side is determined to be chewed, the processor 130 may send a unilateral chew to the right prompter. According to the trigger signal of the trigger signal on the right, the right prompter prompts according to the trigger signal, so that the user knows that he has used the right side for chewing for a long time, and accordingly adjusted to use the left side for chewing. Of course, those skilled in the art can understand that this is only an example and should not be construed as limiting the embodiments of the present application. For example, when the user uses left chewing for a long time, the processor 130 may also send a trigger signal to the right prompter, and the right prompter prompts the user to use the right chewing according to the trigger message.

The prompter 340 may be provided on a wearable device or a mobile terminal, such as smart glasses, headphones, and the like. The prompter 340 may be an indicator light, an alarm, or a spectacle lens of smart glasses, or the like.

A possible implementation manner is to set an indicator light or an alarm on the left or right side of the smart glasses respectively, for users to use the left side for a long time to chew, the left indicator light flashes to remind, or use an alarm to give an alarm. The prompter 340 can be set on the left or right spectacle frame of the smart glasses; it can also be set on the left or right spectacles.

A possible implementation manner is that the subtitle content is displayed on the smart glasses, that is, the display screen of the smart glasses is used as the prompter 340, and the processor 130 sends a prompt message to the smart glasses on the result of the unilateral chewing. For example, the left chewing has been used for a long time. , The prompt message is displayed on the spectacle lens of the smart glasses, and the user can adjust the chewing side according to the prompt message.

A possible implementation manner is to set an indicator light or an alarm on the left or right side of the headset, respectively, and for a user to chew on the left side for a long time, the left indicator light flashes to remind, or an alarm prompts the alarm. The left side mentioned here is, for example, the left earpiece of the headset, and the right side is, for example, the right earpiece of the headset.

A possible implementation manner is that the prompter 340 is disposed on the mobile terminal. When the processor 130 determines that it is unilateral chewing, it sends a trigger signal for unilateral chewing to the mobile terminal. According to the trigger signal, the mobile terminal performs unilateral sound in at least one of the following ways: sound prompt, indicator flashing, alarm sound, and subtitle content display. Chewing tips.

In this embodiment, a unilateral chewing prompt is performed according to a result determined to be unilateral chewing, and the user may be recommended to chew with one side with a small accumulated time, thereby reminding the user to chew evenly.

FIG. 4 is a schematic layout diagram of a first transceiver and a second transceiver in the monitoring device shown in FIG. 3. The first transceiver 110 and the second transceiver 120 are wireless devices, which are respectively disposed under the left frame 401 and the right frame 402 of the smart glasses 400. The processor and the prompter are both disposed in the smart glasses 400 (for example, in the smart glasses 400). The frame of the glasses 400 is connected to the first transceiver 110 and the second transceiver 120 by line). Because the layout diagram in FIG. 4 focuses on the layout of the first transceiver 110 and the second transceiver 120, the processing is not marked in detail. And reminder. Those skilled in the art should understand that this embodiment is only for example, and should not be construed as limiting the protection scope of the present application.

Specifically, the first transceiver 110 is disposed below the left frame 401 of the smart glasses 400, and transmits and receives a fixed-frequency wireless signal to the left chewing muscle (refer to the area shown by the virtual circle 403 in the figure) at a certain time interval t. , Which is the reflected wave on the left. Because the first transceiver 110 is disposed under the left side frame 401, when the user wears the smart glasses 400, the first transceiver 110 is located above the left chewing muscle 403. During the user's chewing process, the first transceiver 110 takes a certain period of time. The wireless signal is transmitted to the left chewing muscle 403 at the interval t, that is, the left reflected wave reflected by the left chewing muscle 403 can be received at a fixed frequency, and the received left reflected wave is sent to the processor. Of course, the first transceiver 110 may also be disposed on the side of the left frame 401 or any other position, as long as it can transmit and receive the left reflection wave reflected by the left chewing muscle 403.

The second transceiver 120 is disposed below the right frame 402 of the smart glasses 400, and transmits and receives a fixed-frequency wireless signal, i.e., the right-side reflected wave, at the time interval t to the right chewing muscle (refer to the area shown by the virtual circle 404 in the figure). . Since the second transceiver 120 is disposed below the right side frame 402, when the user wears the smart glasses 400, the second transceiver 120 is located above the right chewing muscle 404. During the user's chewing process, the second transceiver 120 takes a certain period of time. The wireless signal is transmitted to the right chewing muscle 404 at the interval t, that is, the right reflected wave reflected by the right chewing muscle 404 can be received at a fixed frequency, and the received right reflected wave is sent to the processor. Of course, the second transceiver 120 may also be disposed on the side of the right frame 402 or any other position, as long as it can transmit and receive the right reflected wave reflected by the right chewing muscle 404.

The processor is set in the smart glasses, obtains the spectral width value of the left reflected wave and the spectral width value of the right reflected wave within a period, and determines whether to chew unilaterally according to the two spectral width values. For example, based on the value of the spectral width of the left reflected wave being greater than the value of the spectral width of the right reflected wave, it is determined that the chewing during this period is unilateral and left chewing, the length of the left chewing is recorded, and the cumulative time of the left chewing during the n chewing periods is obtained. long. Similarly, the cumulative length of right chewing during n chewing periods is obtained. For example, if the cumulative length of the left chewing is 3 hours, the cumulative length of the right chewing is 1 hour, and the difference threshold is 30 minutes, then the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing 2 hours, greater than the 30-minute difference threshold, indicating a longer period of chewing with the left side.

After determining that it is chewing on the left, the processor sends a prompt message to the left prompter set on the left frame of the smart glasses, triggering the left prompter to “remove the left side for a longer period of time” reminder. The left prompter is, for example, an indicator light or an alarm. Device. Alternatively, the processor sends a prompt message to the right prompter provided on the right frame of the smart glasses, and triggers the right prompter to “please use the right chew” reminder, such as a light or an alarm. Alternatively, the content of the subtitles can be displayed on the glasses of the smart glasses, that is, the lens is used as a reminder, and the processor sends a prompt message to the prompter and displays the prompt message on the lens, for example, "the left side chewing is being used for a long time. ", Or" Please use the right side for chewing ", or display the cumulative length of the left chewing and the cumulative length of the right chewing on the ophthalmic lens.

In this embodiment, the monitoring device is set to the smart glasses, and the unilateral chewing can be conveniently monitored and prompted by the smart glasses.

FIG. 5 is a schematic diagram of a connection structure of a monitoring device 500 according to another embodiment of the present invention, including a first module 510, a second module 520, and a processing module 530.

The first module 510 is used to obtain at least one left reflected wave of the left masticatory muscle reflection in a period, and sends the obtained left reflected wave to the processing module 530; the second module 520 is used to obtain the right masticated muscle reflection in the period. At least one right-side reflected wave sends the obtained right-side reflected wave to the processing module 530; the processing module 530 obtains the left-side spectrum width value according to the left-side reflected wave, obtains the right-side spectrum width value according to the right-side reflected wave, and at least according to the left-side spectrum width value and The value of the right spectrum width determines whether it is unilateral chewing during this period. The first module 510, the second module 520, and the processing module 530 can be disposed on wearable devices, such as smart glasses, headphones, and the like.

Among them, the first module 510 and the second module 520 can be implemented by, for example, a transceiver, and the processing module 530 can be implemented by, for example, a calculator and a comparator. The calculator obtains the left spectrum width value according to the left reflected wave, and according to the right The reflected wave obtains the right spectrum width value, and outputs the left spectrum width value and the right spectrum width value to the two input ends of the comparator, respectively. The comparator compares according to the above two values, and outputs a signal indicating the comparison result. For example, if the left spectrum width value is greater than the right spectrum width value, a high-level signal is output; otherwise, a low-level signal is output. In another embodiment, if a reminder module is also connected, the high-level or low-level signal is sent to the prompt module, and the prompt module prompts according to the high-level signal or low-level signal. Of course, the first module 510, the second module 520, and the processing module 530 can also be implemented by software programs and stored in a device or a storage medium, which will be described in the following embodiments.

The inventor of the present application has found that when a user chews with the left chewing muscle, the left chewing muscle's action amplitude is greater than the right chewing muscle's action amplitude, resulting in that the left side reflected wave's spectral width value is greater than the right side reflected wave's spectral width value. When a user chews with the right chewing muscle, the action amplitude of the right chewing muscle is greater than that of the left chewing muscle, resulting in that the value of the spectral width of the right reflected wave is greater than the value of the spectral width of the left reflected wave. Similarly, when a user chews with the left and right chewing muscles, the left chewing muscle's motion amplitude is equal to or almost equal to the right chewing muscle's motion amplitude, resulting in the left side reflection wave's spectral width value being equal to or almost equal to the right side reflection wave's spectral width value. . Therefore, according to the magnitude relationship between the spectral width value of the left reflected wave and the spectral width value of the right reflected wave, it can be determined to be left chewing or right chewing, or bilateral chewing.

The processing module 530 determines that the left side chew is based on the spectral width value of the left reflected wave being greater than the right side reflected wave, or determines the right chewing based on the spectral width value of the right reflected wave that is greater than the left side reflected wave. Alternatively, it is determined that the chewing width of the left-side reflected wave is equal to or almost equal to the spectral width value of the right-side reflected wave. For example, the left side reflected wave spectrum curve and the right side reflected wave spectrum curve shown in FIG. 2 are combined, where curve 21 is the user's left chewing face reflection wave spectrum curve, and curve 22 is the user's right chewing face reflection wave spectrum. curve. The value of the spectrum width of the curve 21 is greater than the value of the spectrum width of the curve 22, and the graph indicates that the user uses the left side to chew.

In this embodiment, the spectral width value of the left reflected wave and the spectral width value of the right reflected wave respectively reflect the left chewing condition and the right chewing condition. Therefore, according to the spectral width value of the left reflected wave and the spectral width value of the right reflected wave, , You can determine whether it is unilateral chewing.

In a possible implementation manner, the processing module 530 obtains the chewing duration of unilateral chewing in multiple periods, obtains the cumulative duration of left chewing and the cumulative duration of right chewing, and obtains the cumulative duration of left chewing and right chewing. The cumulative difference in duration is determined based on at least the absolute value of the difference and a duration difference threshold to determine whether it is unilateral chewing during these periods. The duration difference threshold can be set according to the situation. For example, for n chewing periods (n is a natural number), paragraphs 1, 2, 3, ..., n, respectively, to obtain the chewing duration of each chewing period, and accumulate n chewing durations to obtain the cumulative time. The length of the left chewing and the time of the right chewing were recorded separately. The method of recording the duration is, for example, calculating the chewing duration based on the start chewing time and the end chewing time. Of course, those skilled in the art can also use other methods to calculate the chewing duration, which is only an example here and should not be construed as limiting the scope of protection of the present application.

Among them, the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than or equal to the threshold value difference threshold, and it is determined to be unilateral chewing. For the case of unilateral chewing, when the cumulative length of the left chewing is greater than the cumulative length of the right chewing, the left chewing is determined; when the cumulative length of the left chewing is less than the cumulative length of the right chewing, the right chewing is judged. If the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the threshold difference, it is determined as bilateral chewing.

In this embodiment, if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than or equal to the duration difference threshold, it means that the user chews on one side for a long time. Thereby, it is possible to automatically monitor whether unilateral chewing is performed.

FIG. 6 is a schematic diagram of a connection structure of a monitoring device 600 according to another embodiment of the present invention. Compared with the embodiment shown in FIG. 5, the monitoring device 600 in this embodiment may further include a prompt module 640 for processing according to processing. Module 530 determines that it is the result of unilateral chewing, and performs unilateral chewing prompt.

For example, the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing is greater than the threshold difference, and the cumulative length of the left chewing is greater than the cumulative time of the right chewing, indicating that the left chewing is most of the time The prompt module 640 can prompt the left chewing for a long time, or prompt the user to chew on the right, or prompt the user to accumulate the left chewing time and the right chewing cumulative time for the user to adjust the chewing side. Similarly, a unilateral chewing prompt can be provided for the case where the user uses the right chewing.

In a possible implementation manner, the prompting module 640 is one, that is, the processing module 530 sends a triggering signal for one-sided chewing to the prompting module 640, and the prompting module 640 performs prompting according to the triggering signal. In another possible implementation manner, the prompting module 640 includes a left-side prompting module and a right-side prompting module, and performs prompting according to corresponding trigger signals sent by the processing module 530, respectively. The reminder module 640 may be provided on a wearable device or a mobile terminal, such as smart glasses, headphones, and the like. The prompt module 640 may be an indicator light, an alarm, or a spectacle lens of a smart glasses.

One possible implementation manner is to set indicator lights or alarms on the left and right sides of the smart glasses, respectively, for users to use the left side for a long time to chew, the left indicator light flashes to remind, or use the alarm to give an alarm. The prompt module 640 can be set on the left and right spectacle frames of the smart glasses; it can also be set on the left and right spectacles.

A possible implementation manner is that, by displaying the subtitle content on the smart glasses, that is, using the display screen of the glasses of the smart glasses as the reminder module 640, the processing module 530 sends a reminder message of the chewing result to the glasses, For example, left chewing has been used for a long time, and a reminder message is displayed on the ophthalmic lens. The user can see the prompt message and adjust the chewing side accordingly.

A possible implementation manner is to set an indicator light or an alarm on the left or right side of the headset, respectively, for users to use the left side for a long time to chew, the left indicator light flashes to remind, or use an alarm to give an alarm. The left side mentioned here is, for example, the left earpiece of the headset, and the right side is, for example, the right earpiece of the headset.

A possible implementation manner is that the prompt module 640 is disposed on a mobile terminal. When the processing module 530 determines that it is unilateral chewing, it sends a trigger signal for unilateral chewing to the mobile terminal. According to the trigger signal, the mobile terminal performs single chewing by at least one of sound prompting, indicator flashing, alarm sound, and subtitle content display. Side chewing tips. In this embodiment, a unilateral chewing prompt is performed according to the result determined to be unilateral chewing, and the user may be recommended to chew with one side with a shorter chewing duration, thereby reminding the user to chew evenly.

The present invention also provides a unilateral chewing monitoring method. FIG. 7 is a schematic flowchart of a monitoring method according to an embodiment of the present invention. The monitoring method includes the following steps: S710: Obtain at least one left-side reflection wave reflected by the left chewing muscle in a period of time. To obtain the left spectral width value according to the left reflected wave; S720, to obtain at least one right reflected wave of the right chewing muscle during the period, and to obtain the right spectral width value according to the right reflected wave; S730, at least according to the left spectral width value and the right spectral width Value to determine whether it is unilateral chewing during this period.

The inventor of the present application has found that when a user chews with the left chewing muscle, the left chewing muscle's action amplitude is greater than the right chewing muscle's action amplitude, resulting in that the left side reflected wave's spectral width value is greater than the right side reflected wave's spectral width value. When a user chews with the right chewing muscle, the action amplitude of the right chewing muscle is greater than that of the left chewing muscle, resulting in that the value of the spectral width of the right reflected wave is greater than the value of the spectral width of the left reflected wave. Similarly, when the user chews with the left and right chewing muscles, the left chewing muscle's motion amplitude is equal to or almost equal to the right chewing muscle's motion amplitude, resulting in the right side reflection wave's spectral width value equal to or almost equal to the left side reflection wave's spectral width value. . Therefore, according to the magnitude relationship between the spectral width value of the left reflected wave and the spectral width value of the right reflected wave, it can be determined that the left chewing or right chewing, or non-unilateral chewing or bilateral chewing.

Specifically, the left chewing is determined according to the spectral width value of the left reflected wave being greater than the spectral width value of the right reflected wave, or the right chewing is determined according to the spectral width value of the right reflected wave being greater than the spectral width value of the left reflected wave. Alternatively, it is determined that the chewing width of the left-side reflected wave is equal to or almost equal to the spectral width value of the right-side reflected wave. Of course, those skilled in the art should understand that the left chewing or the right chewing is determined here according to the value of the spectrum width, which is only for illustration and should not be construed as limiting the scope of protection of the present application.

In this embodiment, the spectral width value of the left reflected wave and the spectral width value of the right reflected wave respectively reflect the left chewing condition and the right chewing condition. Therefore, according to the spectral width value of the left reflected wave and the spectral width value of the right reflected wave, , You can determine whether it is unilateral chewing.

In a possible implementation manner, the method further includes: comparing a difference between the left spectrum width value and the right spectrum width value with a spectrum width threshold. When the absolute value of the difference between the left spectrum width value and the right spectrum width value is greater than or equal to the When the spectrum width threshold value is determined, it is judged as unilateral chewing, and the one with a larger spectrum width value is judged as the chewing side; otherwise, it may be judged as non-unilateral chewing. The spectrum width threshold can be set according to the situation.

In this embodiment, according to the left spectrum width value and the right spectrum width value, it can be determined whether it is unilateral chewing, such as left chewing or right chewing. Thereby, it is possible to automatically monitor whether unilateral chewing is performed.

FIG. 8 is a schematic flowchart of a monitoring method according to another embodiment of the present application. As shown in FIG. 8, the monitoring method of this embodiment includes the following steps: S710. Obtain at least one left-side reflection wave reflected by the left chewing muscle in a period of time. The left reflection wave obtains the left spectrum width value; S720, obtains at least one right reflection wave of the right masticatory muscle during the period, and obtains the right spectrum width value according to the right reflection wave; S730, at least according to the left spectrum width value and the right spectrum width value, Determine whether it is unilateral chewing during this period; S740, obtain the chewing duration of unilateral chewing in multiple periods, obtain the cumulative duration of left chewing and the cumulative duration of right chewing; S750, obtain the cumulative duration of left chewing and The difference in the cumulative duration of the right chewing, and at least according to the absolute value of the difference and the threshold of the difference in duration, determine whether it is unilateral chewing during these periods.

In step S750, the duration difference threshold can be set according to circumstances. For example, for n chewing periods (n is a natural number), paragraphs 1, 2, 3, ..., n, respectively, to obtain the chewing duration of each chewing period, and accumulate n chewing durations to obtain the cumulative time. And obtain the cumulative duration of the left chewing and the cumulative duration of the right chewing. Based on the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing, and the threshold difference threshold, determine the period Whether it is chewing on one side. The method of recording the duration is, for example, calculating the chewing duration based on the start chewing time and the end chewing time. Of course, those skilled in the art can also use other methods to calculate the chewing duration, which is only an example here and should not be construed as limiting the scope of protection of the present application.

Among them, the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing is greater than or equal to the threshold value of the difference in length, and it is determined to be unilateral chewing; for the case of unilateral chewing, when the cumulative length of the left chewing is greater than The cumulative duration of right chewing is determined to be left chewing; when the cumulative duration of left chewing is shorter than the cumulative length of right chewing, it is judged to be right chewing. On the other hand, if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is less than the threshold difference threshold, it is determined as bilateral chewing.

In this embodiment, if the absolute value of the difference between the cumulative duration of the left chewing and the cumulative duration of the right chewing is greater than the duration difference threshold, it means that the user chews unilaterally for a long time. Thereby, it is possible to automatically monitor whether unilateral chewing is performed.

In this embodiment, it may further include: performing a unilateral chewing prompt according to a result determined to be unilateral chewing. For example, the absolute value of the difference between the cumulative length of the left chewing and the cumulative length of the right chewing is greater than the threshold difference, and the cumulative length of the left chewing is greater than the cumulative time of the right chewing, indicating that the left chewing is most of the time , You can be prompted to chew on the left side for a long time, or prompt the user to chew on the right side, or prompt the user to accumulate the left side and the right side for the user's reference to adjust the chewing side. Similarly, a unilateral chewing prompt can be provided for the case where the user uses the right chewing.

In this embodiment, a unilateral chewing prompt is performed according to a result determined to be unilateral chewing, and the user may be recommended to chew with one side with a small accumulated time, thereby reminding the user to chew evenly.

Those skilled in the art can understand that in the above method, the sequence number of each step does not mean the order of execution. The execution order of each step should be determined by its function and internal logic, and should not deal with the implementation process of the embodiment of the present application. Constitute any limitation.
