Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a control method of transcranial alternating current stimulation equipment, the method based on the embodiment can analyze the optimal synchronization interval of the brain electrical signals of the target brain point location, and then the brain electrical signals of the target brain point location are enabled to achieve phase synchronization by conducting alternating current stimulation on the target brain point location, so that the transcranial alternating current stimulation equipment is applied, and the use requirements of users are met. When the method is specifically applied, the application requirement information can be firstly obtained, the functional scene information is determined based on the application requirement information, and the target brain points are determined based on the functional scene information, wherein the functional scene information is used for reflecting the current use function of the transcranial alternating current stimulation equipment, and the target brain points are multiple. Then, the brain electrical signals of each target brain point position are acquired based on the signal detection part, signal synchronization information is determined based on the brain electrical signals, and an optimal synchronization interval is determined based on the signal synchronization information. And finally, controlling the alternating current stimulation part to perform micro-electrical stimulation on the target brain point location based on the optimal synchronization interval so as to synchronize the phases of the brain electrical signals of the target brain point location. The principle of the transcranial alternating current stimulation device in the embodiment is that alternating current stimulation is carried out on different brain points of a user, so that the brain electrical signals generated by the different brain points are changed, and the brain electrical signals generated by the different brain points are synchronous, so that the stability of the brain electrical signals of the user is ensured.
The transcranial alternating current stimulation device of the embodiment can be applied to a terminal, and the terminal can be a preset mobile terminal, such as a mobile phone or a tablet computer, or can also be an intelligent device, such as a computer or an intelligent television. In a specific application, the terminal of this embodiment is connected to a transcranial alternating current stimulation device. The transcranial alternating current stimulation device comprises a signal detection part and an alternating current stimulation part, wherein the signal detection part is used for detecting an electroencephalogram signal, and the alternating current stimulation part is used for carrying out micro-electric stimulation on a target brain point position through the alternating current signal. Through researches, tACS (transcranial alternating current) can be used for the memory capacity, concentration capacity and the like of covered users, and the difference of defects of individuals is different due to different use requirements of different users. Some users have memory defects, and some users have hyperactivity defects (marked by hyperactivity and actigraphy), so that different functional scene information can be analyzed by the transcranial alternating current stimulation equipment according to the embodiment aiming at different users, and then target brain points are analyzed, so that alternating current stimulation is carried out aiming at the target brain points, and personalized and targeted stimulation effects are achieved.
Specifically, as shown in fig. 1, the control method of the transcranial alternating current stimulation device of the present embodiment includes the steps of:
step S100, obtaining the use requirement information, determining the functional scene information based on the use requirement information, and determining the target brain point location based on the functional scene information.
In a specific application, the terminal of the embodiment first analyzes the user requirement information of the user, where the user requirement information can determine the group of the user, the defect existing in the user, and the defect that the user needs to improve, for example, the memory defect existing in the user a, and the concentration defect existing in the user B, so that the user requirement information of the user a and the user B are different. Further, the terminal may analyze corresponding functional scenario information based on the user's use requirement information, where the functional scenario information reflects the current use function of the transcranial ac stimulation device, for example, a user has a memory defect, so that the corresponding functional scenario information corresponds to a functional scenario with improved memory defect, and B user has a concentration defect, so that the corresponding functional scenario information corresponds to a functional scenario with improved concentration defect. According to research, it is found that alternating current stimulation is performed on different areas of the brain of the user to improve different defects of the user, so that the terminal of the embodiment can determine the corresponding target brain point based on the functional scene information.
In one implementation, when determining the functional scene information, the embodiment includes the following steps:
step S101, voice instruction information is obtained, semantic recognition is carried out based on the voice instruction information, and semantic information is obtained;
step S102, determining the use requirement information based on the semantic information, and extracting keywords from the use requirement information to obtain keyword information;
step S103, determining the functional scene information based on the keyword information.
In a specific application, the transcranial alternating current stimulation device of the embodiment can receive voice instruction information input by a user, and the voice instruction information can be spoken by the user. When the transcranial alternating current stimulation equipment receives the voice command information, the voice command information can be subjected to semantic recognition to obtain semantic information, and the semantic information reflects the operation intention of a user, namely the defect of which aspect the user wants to use the transcranial alternating current stimulation equipment to improve is reflected. At this time, the terminal can determine the information of the use requirement based on the semantic information, and the defect of the user and the defect to be improved are defined. Further, since the use requirement information is determined based on semantic information, which is recognized from the voice instruction information, the semantic information is text information for reflecting the true meaning corresponding to the voice instruction information. Based on the keyword extraction, the terminal can extract the keyword from the use requirement information to obtain the keyword information. The keyword information is a keyword for reflecting the true semantics, that is, a keyword reflecting a defect that the user needs to improve.
Then, the embodiment may obtain a preset function database, where a plurality of vocabulary information for reflecting the function scenario is stored in the function database. Therefore, when the keyword information is matched with the function database, the function scene information is obtained, wherein the function scene information is the currently used function which needs to be started on the transcranial alternating current stimulation equipment, and the defect that the user corresponding to the currently used function needs to be improved is overcome. For example, when the keyword information is a keyword related to improving the memory level, the corresponding functional scene information can be matched based on the functional database to be the memory improving functional scene. When the keyword information is related to improving the concentration level, the corresponding functional scene information can be matched based on the functional database to be the concentration improving functional scene at this time, and further, if the functional scene information is the memory improving functional scene, the embodiment can determine that the target brain point is the temporal lobe and/or the frontal lobe of the brain. And when the functional scene information is a concentration improvement functional scene, determining the target brain point position as a frontal lobe of the brain. In this embodiment, there are a plurality of target brain points, and when performing electroencephalogram detection and micro-electrical stimulation, electroencephalogram detection and micro-electrical stimulation can be performed on these target brain points respectively.
Step 200, acquiring the brain electrical signals of each target brain point based on the signal detection part, determining signal synchronization information based on the brain electrical signals, and determining an optimal synchronization interval based on the signal synchronization information.
The terminal can control the signal detection part of the transcranial alternating current stimulation equipment to collect the brain electrical signals of each target brain point location, then determine whether the brain electrical signals between different target brain point locations are synchronous based on the collected brain electrical signals, namely, obtain signal synchronization information, and then determine the optimal synchronization interval based on the signal synchronization information. The optimal synchronization interval is an interval in which brain electrical signals between different target brain points are in synchronization, and can be used as a basis of micro-electrical stimulation in subsequent steps.
In one implementation, the method in this embodiment, when determining the signal synchronization information, includes the following steps:
step S201, drawing an electroencephalogram waveform chart of the electroencephalogram corresponding to each target brain point based on the electroencephalogram signals;
step S202, based on the electroencephalogram waveform diagrams of different target brain points, amplitude information and frequency information corresponding to the electroencephalogram signals of each target brain point are determined, and based on the amplitude information and the frequency information, phase synchronization information is determined, wherein the phase synchronization information reflects amplitude dissimilarity information and frequency dissimilarity information corresponding to the electroencephalogram signals of different target brain points.
Specifically, in this embodiment, after the electroencephalogram signals corresponding to each target brain point are collected, the collected electroencephalogram signals are drawn into an electroencephalogram signal waveform chart. Amplitude information and frequency information can be reflected from the electroencephalogram waveform. Then, the terminal can compare the amplitude information corresponding to the brain electrical signals of different target brain points and the frequency information corresponding to the brain electrical signals of different target brain points to determine the amplitude dissimilarity information and the frequency dissimilarity information. The amplitude difference information can reflect the synchronous and asynchronous intervals of the amplitude information corresponding to the brain electrical signals of different target brain points, and the frequency difference information can reflect the synchronous and asynchronous intervals of the frequency information corresponding to the brain electrical signals of different target brain points. Therefore, the terminal can determine the same amplitude interval and the same frequency interval of the electroencephalogram signals of different target brain points based on the amplitude dissimilarity information and the frequency dissimilarity information. And then, the interval with the same amplitude and the interval with the same frequency are intersected to obtain the optimal synchronization interval. That is, the optimal synchronization interval determined in the present embodiment is an interval in which the frequencies and amplitudes of the electroencephalogram signals at different brain points are synchronized. When the electroencephalogram signal at the target brain point position of the user is in the optimal synchronization interval, the electroencephalogram signal has high cooperativity, and the electroencephalogram signal is stable, so that the method has remarkable advantages for improving the memory and the concentration of the user.
Because the defects of different users are different, for the users with memory defects, the amplitude information or the frequency information of the brain electrical signals of the temporal lobe of the brain and/or the frontal lobe She Chu of the brain can be asynchronous, and for this reason, the embodiment determines that the optimal synchronization interval can be used as the basis for performing micro-electrical stimulation on the temporal lobe of the brain and/or the frontal lobe of the brain in the subsequent steps. Likewise, for a user with concentration defect, the amplitude information or the frequency information of the brain electrical signal at the forehead lobe of the brain will be asynchronous, so that the embodiment determines that the optimal synchronization interval can be used as the basis for performing micro-electrical stimulation on the forehead lobe of the brain in the subsequent step.
And step S300, controlling the alternating current stimulation part to perform micro-electrical stimulation on the target brain point based on the optimal synchronization interval so as to synchronize phases of brain electrical signals of the target brain point.
The terminal can control the alternating current stimulation part to perform micro-electrical stimulation on the target brain point location by taking the optimal synchronization interval as a basis, and after the micro-electrical stimulation is performed, the brain electrical signals of the target brain point location can be changed, and the frequency information and the amplitude information of the brain electrical signals of different target brain point locations can be synchronized, so that the memory defect or concentration defect of a user is improved.
In one implementation, the method in this embodiment includes the following steps when performing the micro-electrical stimulation:
step 301, determining proportion information of the optimal synchronization interval to a complete electroencephalogram signal fluctuation period based on the optimal synchronization interval;
and step S302, based on the proportion information, acquiring alternating current intensity, and controlling the alternating current stimulation part to perform micro-electrical stimulation on the target brain point location according to the alternating current intensity.
Specifically, after determining the optimal synchronization interval, the terminal may determine the proportion information of the optimal synchronization interval in a complete electroencephalogram signal fluctuation period. The electroencephalogram signal fluctuation period at this time is the average period among the electroencephalogram signals of different target brain points. Then, after the proportion information is obtained, the embodiment can obtain the alternating current intensity and control the alternating current stimulation part to perform micro-electrical stimulation on the target brain point according to the alternating current intensity. In this embodiment, when the proportion information is smaller, the proportion of the optimal synchronization interval in a complete electroencephalogram fluctuation period is smaller, that is, the optimal synchronization interval is smaller, which indicates that there are many unsynchronized places between electroencephalogram signals of different target brain points at this time, so that in order to synchronize the electroencephalogram signals of the target brain points, a larger alternating current intensity is required to control the electroencephalogram signals to become synchronized more quickly. When the proportion information is larger, the proportion of the optimal synchronization interval in a complete electroencephalogram signal fluctuation period is larger, namely the optimal synchronization interval is larger, and the fact that the electroencephalogram signals of different target brain points are in a less unsynchronized place is indicated, so that the electroencephalogram signals can be controlled to become synchronized by the aid of smaller alternating current intensity.
In this embodiment, the micro-electrical stimulation is performed on the target brain points based on the alternating current, and the amplitude peak caused by the asynchronism between the brain electrical signals of different target brain points is mainly suppressed based on the micro-electrical stimulation, so that the brain electrical signals are stable and synchronous, and the memory defect or the concentration defect of the user is improved. In other implementations, the present embodiment may further determine the ac power strength based on the amplitude information and the frequency information in the optimal synchronization interval, so as to eliminate the amplitude spike caused by the unsynchronization by determining the ac power strength.
In summary, the embodiment can analyze the optimal synchronization interval of the brain electrical signal of the target brain point, and then perform alternating current stimulation on the target brain point, so that the brain electrical signal of the target brain point realizes phase synchronization, thereby realizing the application of transcranial alternating current stimulation equipment and meeting the use requirements of users.
Based on the above embodiment, the present invention further provides a control device of a transcranial alternating current stimulation apparatus, where the transcranial alternating current stimulation apparatus includes a signal detection portion and an alternating current stimulation portion, the signal detection portion is used for detecting an electroencephalogram signal, and the alternating current stimulation portion is used for performing micro-electro-stimulation on a target brain point location through the alternating current signal. Specifically, as shown in fig. 2, the control device of the transcranial alternating current stimulation apparatus includes: the point location determination module 10, the interval determination module 20, and the current stimulation module 30. Specifically, the point location determining module 10 is configured to obtain usage requirement information, determine functional scene information based on the usage requirement information, and determine a target brain point location based on the functional scene information, where the functional scene information is used to reflect a current usage function of the transcranial alternating current stimulation device, and the target brain point location has a plurality of target brain points.
