[0036] To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] In this embodiment, the user can be intervened and stimulated by means of acoustic-electric collaborative intervention to affect a specific frequency band and improve the intervention effect of the transcranial direct current stimulation device. Specifically, in implementation, this embodiment first controls a preset intervention stimulation electrode to perform microelectric stimulation when the transcranial direct current stimulation device is working. Then, the binaural frequencies are obtained, the frequency difference is determined based on the binaural frequencies, and it is determined whether the frequency difference meets a preset target frequency range. If the frequency difference meets the target frequency range, then a collaborative intervention is performed based on the frequency difference and the microcurrent output by the intervention stimulation electrode.

[0038] The collaborative intervention control method based on binaural frequency and transcranial direct current in this embodiment can be applied to a terminal device, which can be an intelligent product terminal connected to a transcranial direct current stimulation device, such as a mobile phone, a computer, etc. In specific applications, the terminal device in this embodiment is connected to a transcranial direct current stimulation device. The transcranial direct current stimulation device includes an electroencephalogram detection electrode and an intervention stimulation electrode. The electroencephalogram detection electrode is used to collect the electroencephalogram signal of the user, and the intervention stimulation electrode is used to stimulate the anterior temporal lobe and prefrontal lobe of the brain with a weak current. This transcranial direct current stimulation device can make the user concentrate when working by stimulating the anterior temporal lobe and prefrontal lobe of the user's brain. Moreover, after the transcranial direct current stimulation device in this embodiment performs microcurrent intervention stimulation on the user's brain, for example, by microcurrent stimulating areas such as the dorsolateral prefrontal cortex (DLPFC), it can improve working memory and attention. Further, in addition to the intervention stimulation electrode, the transcranial direct current stimulation device in this embodiment is also provided with a sound wave output part, which is arranged on the left and right sides of the transcranial direct current stimulation device and corresponds to the positions of the user's ears respectively, and is used to output sound wave signals respectively. Therefore, the transcranial direct current stimulation device in this embodiment can output a left-channel sound wave signal and a right-channel sound wave signal, and the frequencies of the left-channel sound wave signal and the right-channel sound wave signal in this embodiment are different, so a frequency difference will be generated. Through research, it is known that specific sound wave frequencies have an impact on the brain gamma wave, and the gamma wave is usually related to higher-order cognitive functions, such as attention and information processing. For example, 40Hz auditory stimulation is considered to be able to induce gamma wave activity, which has been applied in the research of Alzheimer's disease and helps to clear amyloid. Based on this, this embodiment can perform collaborative intervention on the user based on this frequency difference and the intervention stimulation electrode generating microcurrent, thereby stimulating the neuronal activity of the user, effectively improving the stimulation effect on the user, and while improving the user's memory, avoiding the risk of the user suffering from Alzheimer's disease.

[0039] Based on this, this embodiment provides a collaborative intervention control method based on binaural frequency and transcranial direct current. As Figure 1 shown, the method in this embodiment includes the following steps:

[0040] Step S100, when the transcranial direct current stimulation device is working, control the preset intervention stimulation electrode to perform microelectrical stimulation.

[0041] The transcranial direct current stimulation device of this embodiment can be set to a head-mounted type, similar to a helmet or a headband product. When the user wears the transcranial direct current stimulation device, press the start switch set on the transcranial direct current stimulation device to send a start command to start the transcranial direct current stimulation device. The electroencephalogram detection electrode and the intervention stimulation electrode in the transcranial direct current stimulation device are located at different positions and are respectively used to act on different regions of the user's brain to stimulate the corresponding brain regions and help the user improve their energy. In specific applications, when the transcranial direct current stimulation device is worn properly and the transcranial direct current stimulation device is started, at this time, the transcranial direct current stimulation device has not started to intervene and stimulate the user. In order to analyze the effect of the intervention and stimulation, at this time, this embodiment can collect the electroencephalogram signal data of the user's brain to obtain the initial electroencephalogram signal data. The initial electroencephalogram signal data reflects the original electroencephalogram data when the transcranial direct current stimulation device has not started to intervene and stimulate the user's brain. The initial electroencephalogram signal data is used as reference data for analyzing whether the electroencephalogram signal data has changed.

[0042] In one implementation, in this embodiment, after the transcranial direct current stimulation device is started, the contact state between the electroencephalogram detection electrode and the user's brain is obtained. The contact state reflects the contact situation between the electroencephalogram detection electrode and the user's brain, that is, it reflects whether the electroencephalogram detection electrode is in close contact with the user's brain, so as to avoid inaccurate detection of electroencephalogram signal data due to poor contact. In specific applications, when analyzing the contact state between the electroencephalogram detection electrode and the user's brain in this embodiment, it can be analyzed based on the contact area or contact pressure between the electroencephalogram detection electrode and the user's brain. When the contact area between the electroencephalogram detection electrode and the user's brain exceeds the preset area threshold, it can be explained that the electroencephalogram detection electrode is in relatively close contact with the user's brain, and the contact state meets the preset requirements (that is, the electroencephalogram detection electrode is in place in contact with the user's brain). Similarly, when the contact pressure between the electroencephalogram detection electrode and the user's brain exceeds the preset pressure threshold, it can be explained that the electroencephalogram detection electrode is in relatively close contact with the user's brain, and the contact state meets the preset requirements. When it is determined that the contact state meets the preset requirements, this embodiment can trigger the electroencephalogram detection electrode to work and obtain the initial electroencephalogram signal data. After the electroencephalogram detection electrode obtains the initial electroencephalogram signal data, the collected initial electroencephalogram signal data can be sent to a preset APP, and the terminal device can record the initial electroencephalogram signal data based on the preset APP for subsequent steps to use the initial electroencephalogram signal data for corresponding analysis.

[0043] Next, this embodiment can activate the transcranial direct current stimulation device and control the intervention stimulation electrode to output a microcurrent with default stimulation information to achieve microelectrical stimulation. The default stimulation information in this embodiment can be the preset microcurrent intensity and stimulation duration, or the microcurrent intensity and stimulation duration when the intervention stimulation electrode performed microelectrical stimulation last time. For this purpose, this embodiment can obtain the preset microcurrent intensity and stimulation duration in the intervention stimulation electrode, and use the preset microcurrent intensity and stimulation duration as the default stimulation information to achieve microelectrical stimulation. Or, obtain the microcurrent intensity and stimulation duration when the intervention stimulation electrode performed microelectrical stimulation last time, and use the microcurrent intensity and stimulation duration when the intervention stimulation electrode performed microelectrical stimulation last time as the default stimulation information to achieve microelectrical stimulation.

[0044] In other implementation manners, a mode selection menu is provided in the transcranial direct current stimulation device of this embodiment, and a plurality of selectable intervention stimulation modes are provided in the mode selection menu. To better assist the user in selecting an intervention stimulation mode, this embodiment can recommend modes to the user. A user login interface can be set in the mode selection menu of this embodiment, and the user can enter their identity information in the user login interface. After receiving the identity information, the transcranial direct current stimulation device can obtain the historical usage data corresponding to the identity information. These historical usage data are the data of the user using the transcranial direct current stimulation device in the past period of time. Therefore, based on these historical usage data, the microcurrent intensity and stimulation duration when the intervention stimulation electrode performed microelectrical stimulation last time can be obtained, and the microcurrent intensity and stimulation duration when the intervention stimulation electrode performed microelectrical stimulation last time can be used as the default stimulation information for intervention.

[0045] In another implementation manner, to improve the microelectrical stimulation effect of the intervention stimulation electrode and avoid the insufficient effect caused by individual differences, for example, the skull thickness and brain structure of different people may affect the microelectrical stimulation effect. Therefore, this embodiment can adjust the above default stimulation information based on individual differences. Specifically, this embodiment can be based on the MRI data or CT data provided by the user in advance, and then use the user's MRI data or CT data to construct a skull-brain model, and calculate the optimal electrode position and optimal current intensity of this user. In this way, the terminal can fit the intervention stimulation electrode in the transcranial direct current stimulation device to the optimal electrode position, and adjust the microcurrent output by the intervention stimulation electrode to the optimal current intensity, so as to provide the best microelectrical stimulation effect for this user. In addition, this embodiment can also let the user apply microelectrical stimulation in a specific cognitive task. For example, when the user uses the transcranial direct current stimulation device, the user is synchronously allowed to perform a memory training task, so as to enhance the microelectrical stimulation effect by using the neural plasticity window period.

[0046] Step S200: Obtain the binaural frequencies, determine the frequency difference based on the binaural frequencies, and determine whether the frequency difference meets a preset target frequency range.

[0047] To achieve collaborative control, in this embodiment, the binaural frequencies can be obtained. The binaural frequencies include the first frequency corresponding to the left-channel acoustic wave signal and the second frequency corresponding to the right-channel acoustic wave signal. Specifically, in this embodiment, the acoustic wave output parts provided on the transcranial direct current stimulation device can be used to output the left-channel acoustic wave signal and the right-channel acoustic wave signal respectively. The first frequency and the second frequency in this embodiment are different. Therefore, a difference can be determined between the first frequency and the second frequency, and this difference is the frequency difference. In this embodiment, it is necessary to determine whether this frequency difference meets the preset target frequency range. Research shows that specific acoustic frequencies have an impact on the brain's gamma waves, and gamma waves are usually related to higher cognitive functions such as attention and information processing. For example, 40 Hz auditory stimulation is considered to be able to induce gamma wave activity, which has applications in the research of Alzheimer's disease and helps to clear amyloid. However, due to individual differences or with age, auditory stimulation below 40 Hz may be more conducive to inducing gamma wave activity, such as 32 Hz. Based on this, the target frequency range in this embodiment is set at 32 - 40 Hz. The target frequency range in this embodiment is the result obtained by analyzing the frontal electroencephalogram signals of users of different ages, so that this embodiment can be applied to a wider user group. Only when the frequency difference is within this target frequency range can collaborative intervention be carried out. Therefore, after obtaining this frequency difference in this embodiment, the frequency difference is matched with the target frequency range to determine whether the frequency difference meets the preset target frequency range.

[0048] Step S300: If the frequency difference meets the target frequency range, perform collaborative intervention based on the frequency difference and the microcurrent output by the intervention stimulation electrode.

[0049] When it is determined that the frequency difference meets the target frequency range, in this embodiment, it can be determined that at this time, the frequency difference is within 32 - 40 Hz, and auditory stimulation within this range can induce the brain's gamma wave activity and help to clear amyloid. Therefore, when the transcranial direct current stimulation device outputs a microcurrent through the intervention stimulation electrode, it can simultaneously output the left-channel acoustic wave signal and the right-channel acoustic wave signal through the acoustic wave output part, and then can perform intervention stimulation on the user based on the microcurrent and the frequency difference at the same time, thereby stimulating the user's neuronal activity, effectively improving the stimulation effect on the user, and while improving the user's memory, avoiding the risk of the user suffering from Alzheimer's disease.

[0050] In this embodiment, the left-channel acoustic wave signal and the right-channel acoustic wave signal are not fixed. As long as the frequency difference between the two satisfies the target frequency range, cooperative intervention can be achieved. Therefore, if the frequency difference between the two does not meet the target frequency range, the left-channel acoustic wave signal and the right-channel acoustic wave signal are adjusted until the frequency difference meets the target frequency range. For example, if the first frequency of the left-channel acoustic wave signal is controlled to be 160 Hz and the second frequency of the right-channel acoustic wave signal is controlled to be 200 Hz, the frequency difference between the two can be controlled to be 40 Hz. It can be seen that the left-channel acoustic wave signal and the right-channel acoustic wave signal of the present invention can be adjusted according to requirements. In the APP of the terminal device, a corresponding interface can be set to adjust the acoustic wave frequencies (i.e., the first frequency and the second frequency) output by the acoustic wave output parts on both sides, so as to control the acoustic wave output parts on both sides to emit acoustic wave signals with corresponding frequencies, so that the frequency difference between the two meets the target frequency range. In other implementation manners, in this embodiment, the frequency difference can be directly set in the APP of the terminal device. For example, if the frequency difference is set to 38 Hz, the APP will automatically match the acoustic wave frequencies output by the acoustic wave output parts on both sides. For example, the first frequency of the left-channel acoustic wave signal is controlled to be 208 Hz, and the second frequency of the right-channel acoustic wave signal is controlled to be 170 Hz. In this way, the frequency difference between the two acoustic wave frequencies is 38 Hz, thus meeting the target frequency range.

[0051] In another implementation manner, during the cooperative intervention process of this embodiment, real-time electroencephalogram signal data can be obtained. Then, based on the real-time electroencephalogram signal data, the intervention effect is evaluated, and based on the intervention effect, the microcurrent output by the intervention stimulation electrode and / or the acoustic wave signal output by the acoustic wave generating part are adjusted in real time. For example, when it is found that the difference between the real-time electroencephalogram signal data and the initial electroencephalogram signal data is not large after cooperative intervention, that is, the electroencephalogram wave fluctuation is not large before and after the intervention. Therefore, the microelectrical stimulation of the intervention stimulation electrode and / or the acoustic wave frequency emitted by the acoustic wave generating part can be adjusted in real time, so as to improve the intervention effect.

[0052] In summary, in this embodiment, first, when the transcranial direct current stimulation device is working, the preset intervention stimulation electrode is controlled to perform microelectrical stimulation. Then, the binaural frequencies are obtained, and based on the binaural frequencies, the frequency difference is determined, and it is determined whether the frequency difference meets the preset target frequency range. Finally, if the frequency difference meets the target frequency range, cooperative intervention is performed based on the frequency difference and the microcurrent output by the intervention stimulation electrode. This embodiment can perform intervention stimulation on the user through the acoustic-electric cooperative intervention method to achieve an impact on a specific frequency band and improve the intervention effect of the transcranial direct current stimulation device.
