It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as herein.

[0053] In view of the above-mentioned defects of the prior art, the present invention provides a sleep aid device with automatic switching modules, the device comprising an electrical stimulation module and a control module; the electrical stimulation module comprises: a transcranial electrical stimulation module and a transcutaneous electrical stimulation module; the transcranial electrical stimulation module contacts the user's ear; the transcutaneous electrical stimulation module contacts the user's forehead; the transcranial electrical stimulation module and the transcutaneous electrical stimulation module are both used to emit current to stimulate the user's cranial nerves, and the current intensity of the transcranial electrical stimulation module is less than the current intensity of the transcutaneous electrical stimulation module; the control module is used to obtain the user's electroencephalographic activity within a preset time period; determine the first usage priority corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the electroencephalographic activity; obtain the user's hand movement trajectory within the preset time period; determine the second usage priority corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the hand movement trajectory; and regulate the operation of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module according to the first usage priority and the second usage priority. The present invention integrates a transcranial electrical stimulation module and a transcutaneous electrical stimulation module into a sleep aid device, and dynamically switches the operation of the two modules through EEG activity and hand movement trajectory. Since the two modules act on different parts of the user's body respectively, it can effectively solve the problem that current wearable sleep aid devices only act on one part of the body, and once they fall off, the sleep aid effect will be reduced.

[0054] like Figure 1 As shown, the device includes an electrical stimulation module 01 and a control module 02;

[0055] The electrical stimulation module 01 includes: a transcranial electrical stimulation module and a transcutaneous electrical stimulation module; the transcranial electrical stimulation module contacts the user's ear; the transcutaneous electrical stimulation module contacts the user's forehead; the transcranial electrical stimulation module and the transcutaneous electrical stimulation module are both used to emit current to stimulate the user's cranial nerves, and the current intensity of the transcranial electrical stimulation module is less than the current intensity of the transcutaneous electrical stimulation module;

[0056] The control module 02 is used to obtain the EEG activity of the user within a preset time period; determine the first usage priorities corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively based on the EEG activity; obtain the hand movement trajectory of the user within the preset time period; determine the second usage priorities corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively based on the hand movement trajectory; and regulate the operation of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module based on the first usage priority and the second usage priority.

[0057] Specifically, this embodiment integrates a transcranial electrical stimulation module (CES) and a transcutaneous electrical stimulation module (TENS), the former contacts the user's ear, and the latter contacts the user's forehead. The two act on different parts of the user's body and have different action intensities. Users have different needs for sleep aids at different EEG activity levels, and different sleep aid needs require different current intensities to meet. For example, the higher the EEG activity, the higher the need for sleep aid, and an electrical stimulation module with a stronger current intensity is required to help sleep. Therefore, this embodiment first uses EEG activity to determine the first use priority of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module. Secondly, since some users will unconsciously wave their hands during sleep, it is easy to cause the worn sleep aid device to be knocked off. Once knocked off, the sleep aid effect will be greatly reduced. In this embodiment, when one electrical stimulation module is knocked off, the other electrical stimulation module can continue to work to ensure the sleep aid effect, so this embodiment will also determine the risk of the two electrical stimulation modules being knocked off based on the hand movement trajectory, and then determine the second use priority of the two electrical stimulation modules. Finally, the first usage priority and the second usage priority are combined to determine which electrical stimulation module to use first, so as to meet the user's sleep-aiding needs and ensure the sleep-aiding effect as much as possible.

[0058] In one implementation, obtaining the EEG activity of the user within a preset time period includes:

[0059] Acquire brain wave data of the user within the preset time period, and determine two waveform envelope data according to the brain wave data;

[0060] Determine a plurality of pairs of data points that are evenly distributed in the two waveform envelope data, and obtain a first distance value between two data points in each pair of data points;

[0061] Determine an average distance value of two waveform envelope data according to the first distance values ​​corresponding to each pair of data points;

[0062] The EEG activity is determined according to the average distance value.

[0063] Specifically, in order to easily extract the information reflected by the brain wave data, the present embodiment will first convert the brain wave data into two waveform envelope data, one waveform envelope data is obtained based on the connection of each peak value in the brain wave data, and the other waveform envelope data is obtained based on the connection of each valley value of the brain wave data. Therefore, the relative distance between the two waveform envelope data can reflect the gap between the peak value and the valley value in the brain wave data, thereby reflecting the fluctuation amplitude of the brain wave data. In order to obtain a more reliable and true relative distance between two waveform envelope data, the present embodiment selects several pairs of data points evenly distributed on the two waveform envelope data, each pair of data points corresponds to a horizontal coordinate, and by obtaining the average value of the relative distance between the two data points in each pair of data points, the distance between the two waveform envelope data can be determined, and then the fluctuation amplitude of the brain wave data can be accurately determined, and then the fluctuation amplitude of the brain wave data can be used to evaluate the current brain wave activity of the user.

[0064] In one implementation, determining the first usage priorities corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the EEG activity includes:

[0065] Determining a sleep state category of the user according to the EEG activity;

[0066] When the sleep state category is awake, the first use priority of the transcranial electrical stimulation module is lower than the first use priority of the transcutaneous electrical stimulation module;

[0067] When the sleep state category is a quiet state, the first usage priority of the transcranial electrical stimulation module is greater than the first usage priority of the transcutaneous electrical stimulation module.

[0068] Specifically, the user's EEG activity is different in different sleep states. Usually, the sleep state is mainly divided into four types: awake state, calm state, light sleep state and deep sleep state. The EEG activity of the four sleep states decreases successively, and the need for sleep aid is usually related to the first two sleep states. The current intensity of the transcutaneous electrical stimulation module is higher than that of the transcranial electrical stimulation module, so the former has a better sleep aid effect. Since the EEG activity corresponding to the awake state is higher than that corresponding to the calm state, the need for sleep aid is greater in the awake state than in the calm state. This embodiment sets the user to give priority to the transcutaneous electrical stimulation module in the awake state, and give priority to the transcranial electrical stimulation module in the calm state. Thereby achieving dynamic switching of different electrical stimulation modules according to the user's sleep state.

[0069] In one implementation, the obtaining of the hand movement trajectory of the user within the preset time period includes:

[0070] Acquire a plurality of posture images corresponding to the upper body of the user within the preset time period,

[0071] Determine, according to each of the posture images, a plurality of moving parts of the user's upper body and the moving directions corresponding to each of the moving parts;

[0072] Determine an average moving direction according to each of the moving directions, and take the moving part corresponding to the moving direction with the largest difference from the average moving direction as the target moving part;

[0073] The moving trajectory of the target moving part is determined according to each of the posture images to obtain the hand moving trajectory.

[0074] Specifically, some users may flip over their bodies in addition to waving their hands while sleeping, so there may be multiple moving parts detected in the multiple posture images collected continuously. However, compared with the hands, the movement directions of other parts of the body are relatively limited, and usually they are horizontal displacements based on the flipping of the body. Only the movement directions of the hands are relatively diverse. Therefore, these posture images can be used to first determine the multiple moving parts that have been displaced and the moving directions of each moving part, and then the moving part whose moving direction is obviously different from that of other moving parts is determined as the target moving part, that is, the user's hand. Finally, the movement trajectory of the target moving part is extracted through each posture image, that is, the hand movement trajectory. Compared with traditional image analysis, this embodiment determines the area of ​​the hand in the image by the moving direction, avoids the computational overhead of feature extraction, feature analysis and other links, and can quickly and easily identify the area where the hand is located in the image.

[0075] In one implementation, determining the second usage priorities corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the hand movement trajectory includes:

[0076] Determining second distance values ​​between the user's hand and the transcranial electrical stimulation module and the transcutaneous electrical stimulation module, respectively, according to the hand movement trajectory;

[0077] Determining the knockdown risk values ​​corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the second distance value between the transcranial electrical stimulation module and the transcutaneous electrical stimulation module;

[0078] The second usage priorities respectively corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module are determined according to the knock-off risk values ​​of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module.

[0079] Specifically, the hand movement trajectory can be used to determine whether the user's hand is gradually approaching the transcranial electrical stimulation module and the transcutaneous electrical stimulation module, that is, the second distance value between the user's hand and the transcranial electrical stimulation module and the transcutaneous electrical stimulation module is obtained, and then the corresponding risk values ​​of being knocked off the transcranial electrical stimulation module and the transcutaneous electrical stimulation module are determined. The higher the risk value of being knocked off, the lower the possibility that the module will play a normal sleep-aiding role in the future. Therefore, the module with a lower risk value of being knocked off should be used first, that is, the risk value of being knocked off is inversely proportional to the second usage priority.

[0080] In one implementation, regulating the operation of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module according to the first usage priority and the second usage priority includes:

[0081] Performing a weighted calculation according to the first usage priority and the second usage priority, wherein a weight value of the second usage priority is greater than a weight value of the first usage priority;

[0082] The module with the largest weighted result between the transcranial electrical stimulation module and the transcutaneous electrical stimulation module is used as the operating module.

[0083] Specifically, this embodiment combines the first use priority and the second use priority in a weighted manner. Since the first use priority is related to the sleep-aiding effect, and the second use priority is related to whether the module can normally play the role of sleep-aiding in the future, and the sleep-aiding effect is only produced under the premise that the module functions stably, this embodiment sets the weight value of the second use priority to be greater than the weight value of the first use priority. The module with the larger weighted result may have better sleep-aiding effect and stability, so the module with the largest weighted result is preferentially used as the running module.

[0084] In one implementation, the method further includes:

[0085] Determining the degree of occlusion of the running module according to each of the posture images;

[0086] When the degree of shielding is greater than a preset threshold, module switching is performed.

[0087] Specifically, if the running module is blocked, it means that it may be covered by the user's body. In order to ensure that the sleep aid device can stably exert the sleep aid effect, this embodiment determines whether to switch modules according to the blocking degree of the running module.

[0088] Based on the above embodiments, the present invention further provides a method for automatically switching modules of a sleep aid device, the method being applied to the sleep aid device, the device comprising an electrical stimulation module, the electrical stimulation module comprising: a transcranial electrical stimulation module and a transcutaneous electrical stimulation module; the transcranial electrical stimulation module is in contact with the ear of the user; the transcutaneous electrical stimulation module is in contact with the forehead of the user; the transcranial electrical stimulation module and the transcutaneous electrical stimulation module are both used to emit current to stimulate the cranial nerves of the user, the current intensity of the transcranial electrical stimulation module is less than the current intensity of the transcutaneous electrical stimulation module; Figure 2 As shown, the method includes:

[0091] Step S300, obtaining the hand movement trajectory of the user within the preset time period;

[0092] Step S400, determining the second usage priorities corresponding to the transcranial electrical stimulation module and the transcutaneous electrical stimulation module respectively according to the hand movement trajectory;

[0093] Step S500: regulating the operation of the transcranial electrical stimulation module and the transcutaneous electrical stimulation module according to the first usage priority and the second usage priority.

When the computer program is executed by the processor, a method for automatically switching modules of a sleep aid device is implemented.
