With the improvement of the quality of life, people pay more attention to how to improve the sleep quality. The high-quality sleep can enable the brain and the body of people to rest and recover, improve the work and learning efficiency of people and relieve the emotion.
Currently, there are many sleep-aid products on the market that help users to enter a sleep state as soon as possible. When a user falls asleep, the sleep state and emotion of the user may change, and the conventional sleep-aiding product can only work at a fixed position with fixed parameters and cannot automatically adjust according to the physiological characteristics of the user in the falling asleep process, so that the sleep-aiding effect is poor.
Aiming at the defects of the prior art, the invention provides a sleep assisting device, a method, a terminal and a storage medium based on multiple types of electric stimulation, wherein the device comprises a control module and an electric stimulation module, the sleep state data and the change frequency of the positions of the eyebrows of a target user in a preset time period are determined through the control module, and the electric stimulation module is controlled according to the sleep state data and the change frequency of the positions of the eyebrows; the electrical stimulation module comprises a transcranial electrical stimulation module and a percutaneous electrical stimulation module, the transcranial electrical stimulation module and the percutaneous electrical stimulation module are both used for sending current to stimulate the cranial nerves of the target user, and the current intensity of the transcranial electrical stimulation module is smaller than that of the percutaneous electrical stimulation module. According to the invention, the control module dynamically controls the transcranial electrical stimulation module and the percutaneous electrical stimulation module to work based on the sleep state data of the user and the change frequency of the positions of the eyebrows, so that the problems that the existing sleep-assisting product is single in action position and cannot be automatically adjusted according to physiological characteristics of the user in the sleep process, and the sleep-assisting effect is poor are solved.
For example, the following steps are carried out: when a target user sleeps, the sleep assisting device collects the electroencephalogram signals of the target user within a preset time period through the control module, and judges the sleep state of the target user at the moment according to the electroencephalogram signals of the target user. In addition, the control module can also acquire the facial image of the target user within a preset time period, and determine the eyebrow position change frequency of the target user according to the facial image of the target user. After the control module determines the sleep state and the change frequency of the positions of the eyebrows of the target user, the electrical stimulation module can be controlled according to the sleep state and the change frequency of the positions of the eyebrows, and the effect of improving the sleep quality of the target user is achieved. For example, when the sleep state of the target user is a waking state, the stimulation intensity of the electrical stimulation module needs to be correspondingly increased, and if the user is in a shallow sleep state or a deep sleep state, the stimulation intensity of the electrical stimulation module needs to be reduced, so that the interference to the sleep of the user is reduced; when the change frequency of the positions of the eyebrows and the eyes of the user is too high, the user is not comfortable at the moment, and the electrical stimulation module needs to be adjusted/switched, so that the target user can keep comfortable, and the sleep quality cannot be influenced by the auxiliary sleep device.
Exemplary devices
As shown in fig. 1, the device control module 01 and the electrical stimulation module 02;
the control module 01 is configured to acquire an electroencephalogram signal of a target user within a preset time period, and determine sleep state data according to the electroencephalogram signal, where the sleep state data is one of a waking state, a resting state, a light sleep state, and a deep sleep state;
acquiring a plurality of frames of facial images of the target user in the preset time period, and determining the eyebrow position change frequency of the target user according to each frame of facial image;
and controlling the electrical stimulation module according to the sleep state data and the change frequency of the positions of the eyebrows and the eyes.
The sleep assisting device in the embodiment comprises a control module and an electrical stimulation module. The control module acquires relevant parameters of the target user capable of reflecting the sleep quality in the sleep process, and controls the electrical stimulation module according to the parameters, so that the effect of improving the sleep quality of the target user is achieved. Specifically, the sleep quality of the target user is reflected by the sleep state data and the frequency of the change in the position of the eyebrows. The control module firstly obtains the electroencephalogram signal of the target user in a preset time period, and determines the sleep state data of the target user in the preset time period according to the electroencephalogram signal. Because the fluctuation of the electroencephalogram signal of the target user is different between the waking state and the sleeping state, according to the fluctuation degree of the electroencephalogram signal, the sleeping state data of the target user is divided into the waking state, the resting state, the light sleeping state and the deep sleeping state. And after the control module determines the sleep state data of the target user, the control module accurately controls the electrical stimulation module according to the determined sleep state data.
For the change frequency of the eyebrow positions, because the transcutaneous electrical stimulation module is located at the forehead of the target user, which easily causes a large foreign body sensation to the target user, the embodiment determines the change frequency of the eyebrow positions of the target user in a preset time period by acquiring facial images of a plurality of frames of the target user in the preset time period and analyzing the facial images, and determines whether the target user has an uncomfortable condition due to the foreign body sensation according to the change frequency of the eyebrow positions of the target user. Generally, when the transcutaneous electrical stimulation module is operated, if the eyebrow position of the target user is constantly changed, it indicates that the target user may be interfered by the instrument and is not comfortable. Therefore, in this embodiment, the determination is performed according to the frequency of the change of the eyebrow position of the target user, and when the frequency of the eyebrow position of the target user is greater than a certain value, it is considered that the target user may have an uncomfortable condition, and the electrostimulation module needs to be switched, so that the target user can be maintained in a comfortable state.
In an implementation manner, in this embodiment, the control module determines that the sleep state data and the eyebrow position change frequency of the target user are performed simultaneously, so that the electrical stimulation module is controlled according to the sleep state data and the eyebrow position change frequency within the same preset time period, the accuracy of sleep quality judgment of the target user is enhanced, the occurrence of a situation that the target user is interfered in the sleep process and is changed into the awake state from the sleep state is reduced, and the sleep quality of the target user is ensured.
The electrical stimulation module 02 includes: a transcranial electrical stimulation module and a percutaneous electrical stimulation module; the transcranial electrical stimulation module is in contact with the ear of the target user; the transcutaneous electrical stimulation module is in contact with the forehead of the target user; the transcranial electrical stimulation module and the percutaneous electrical stimulation module are both used for sending current to stimulate the cranial nerves of the target user, and the current intensity of the transcranial electrical stimulation module is smaller than that of the percutaneous electrical stimulation module.
Specifically, the electrical stimulation module in this embodiment includes two parts, namely a transcranial electrical stimulation module (CES) and a transcutaneous electrical stimulation module (TENS), which both stimulate the brain through low-intensity micro current, change abnormal brain waves of the brain of the target user, and promote the brain to secrete neurotransmitters and hormones that promote sleep and mood. The difference is that the transcranial electrical stimulation module (CES) is in contact with the ear of the target user, and stimulation is performed from behind the ear, and the stimulation signal has a long path to the brain. The transcutaneous electrical stimulation module (TENS) is in contact with the forehead of the target user, and the stimulation signal thereof directly acts on the cerebral cortex, and the path is relatively shorter, so that the transcutaneous electrical stimulation module (TENS) is more effective in stimulating the brain of the human body than the transcranial electrical stimulation module (CES). Because the transcranial electrical stimulation module (CES) is contacted with the ear of the target user, compared with the fact that the transcutaneous electrical stimulation module (TENS) needs to be attached to the forehead of the target user, the transcranial electrical stimulation module (CES) brings less foreign body sensation to the target user and is more comfortable in use feeling. Therefore, in the actual use process, the control module can dynamically switch the transcranial electrical stimulation module and the transcutaneous electrical stimulation module according to the state of the target user.
In one implementation, the determining a frequency of eyebrow position changes of the target user according to the facial image of each frame includes:
acquiring position variation of an eyebrow area in the face images of two adjacent frames;
acquiring the proportion of the position variation with the numerical value larger than a preset value in the position variation;
and determining the eyebrow position change frequency according to the ratio, wherein the ratio is in direct proportion to the eyebrow position change frequency.
Specifically, after a plurality of frames of facial images of a target user within a preset time period are acquired, the facial images of the frames are input into a preset deep learning model for analysis and learning, and the positions of eyebrow areas in the facial images of the facial image frames are obtained; and comparing the positions of the eyebrow areas in the face images in the two adjacent frames to obtain the position variation of the eyebrow areas. When the number of acquired face image frames is N, the number of position variations that can be determined is N-1. And comparing the value of each position variation with a preset value, and when the value of the position variation is larger than the preset value, indicating that the facial expression of the target user at the moment is changed greatly. And counting the quantity M larger than the preset value in all the position variation in the preset time period, and calculating M/(N-1). And determining the eyebrow position change frequency according to M/(N-1). Generally, the larger M/(N-1), the higher the frequency of change in the position of the eyebrows, and the higher the possibility of discomfort and interference to the user.
In one implementation, the determining the sleep state data from the brain electrical signal includes:
determining the brain electrical activity corresponding to the target user according to the brain electrical signal;
acquiring a plurality of preset numerical value intervals, wherein each numerical value interval corresponds to different sleep states;
and determining a target numerical value interval from each numerical value interval according to the brain electrical activity, and determining the sleep state data according to the sleep state corresponding to the target numerical value interval.
Specifically, in order to determine the specific sleep state of the target user, the control module acquires an electroencephalogram signal within a preset time period, and determines the electroencephalogram activity corresponding to the target user according to the electroencephalogram signal. When the fluctuation of the electroencephalogram signal is large, it is indicated that neurons of the brain of the target user are in an active state, the electroencephalogram activity corresponding to the target user is also large, correspondingly, when the fluctuation of the electroencephalogram signal is small, the electroencephalogram activity of the target user is also small, and the target user may be in a rest state. In this embodiment, a plurality of preset value intervals are set according to the size of the electroencephalogram activity, and the preset value intervals respectively correspond to different sleep states, such as a waking state, a calm state, a light sleep state, a deep sleep state and the like, according to the values from large to small, wherein the value intervals and the sleep states have a one-to-one correspondence relationship. In this embodiment, after determining the brain activity of the target user, the control module determines which value range the brain activity falls into, and thus obtains the target value range. And determining the sleep state data of the target user according to the sleep state corresponding to the target value interval. For example, the predetermined value intervals are [0,3], [4,6], [7,9], [10,12], which correspond to a deep sleep state, a light sleep state, a calm state, and a wake state, respectively. If the acquired brain activity of the target user is 5, determining that the sleep state data of the target user is in a shallow sleep state according to the brain activity of the target user. According to the embodiment, the sleep state data is determined according to the electroencephalogram signals by acquiring the electroencephalogram signals of the target user, so that the electrical stimulation module can be controlled more accurately, and the self-adaptive capacity of the sleep auxiliary device for improving the sleep quality of the target user is improved.
In one implementation, the controlling the electrical stimulation module according to the sleep state data and the eyebrow position variation frequency includes:
when the sleep state data is in a waking state, starting the percutaneous electrical stimulation module for a preset time length;
judging whether the sleep state data change within the preset time length or not, and judging whether the eyebrow position change frequency is higher than a frequency threshold or not when the sleep state data do not change;
when the change frequency of the eyebrow and eye positions is higher than the frequency threshold, stopping the percutaneous electrical stimulation module and starting the transcranial electrical stimulation module;
when the frequency of the change of the positions of the eyebrows and the eyes is lower than or equal to the frequency threshold value, adjusting the working parameters of the percutaneous electric stimulation module.
In particular, since the transcutaneous electrical stimulation module is more efficient than the transcranial electrical stimulation module, when the control module detects that the target user is in a waking state, the control module first activates the transcutaneous electrical stimulation module in order to enable the target user to rapidly enter a sleeping state. The method comprises the steps that whether the sleep state of a target user changes or not is continuously detected within a preset working duration of a transcutaneous electrical stimulation module, if the sleep state of the target user does not change all the time and is kept in a waking state, whether the change frequency of the eyebrow-eye position of the target user is higher than a preset frequency threshold or not is judged, and if the change frequency of the eyebrow-eye position of the target user is higher than the frequency threshold, the transcutaneous electrical stimulation module possibly causes serious foreign body sensation on the forehead of the target user, and therefore the target user cannot fall asleep. At the moment, the control module controls the percutaneous electrical stimulation module to stop working and switches to start the transcranial electrical stimulation module. Because the transcranial electrical stimulation module is in contact with the ears of the target user, the contact area is smaller than that of the transcutaneous electrical stimulation module, and therefore foreign body sensation can be effectively reduced. If the change frequency of the eyebrow and eye positions of the target user is lower than or equal to the frequency threshold, it is indicated that the target user cannot fall asleep because the target user is uncomfortable to wear the transcutaneous electrical stimulation module, but the working parameters of the transcutaneous electrical stimulation module are not set correctly, and the working parameters of the transcutaneous electrical stimulation module are adjusted through the control module, such as increasing the current intensity and frequency, increasing the pulse duration and the like, so that the target user can be ensured to rapidly enter a sleep state. According to the embodiment, the two electrical stimulation modules are dynamically regulated according to the sleep state and the change frequency of the positions of the eyebrows and the eyes of the target user, so that the experience of the target user wearing the sleep-assisting product can be effectively improved, and the target user can be enabled to quickly enter the sleep state.
In one implementation, the determining whether the sleep state data changes within the preset time further includes:
and judging whether the sleep state data change within the preset time length, and stopping the percutaneous electrical stimulation module and starting the transcranial electrical stimulation module when the sleep state data change from a waking state to a calm state.
Specifically, if the sleep state data of the target user in the preset working duration of the transcutaneous electrical stimulation module is changed from a waking state to a calm state, which indicates that the target user has started to slowly enter the sleep state and does not need strong stimulation to promote the target user to fall asleep, the use of the transcutaneous electrical stimulation module is suspended, and the transcranial electrical stimulation module is started, so that the foreign body sensation and the stimulation intensity generated by the device to the target user are reduced, and the target user is prevented from being disturbed to fall asleep.
In one implementation, the activation of the transcranial electrical stimulation module further comprises:
acquiring the sleep state data of the target user at preset time intervals, and judging whether the sleep state data changes or not;
when the sleep state data is changed from a calm state to a waking state, stopping the transcranial electrical stimulation module and starting the percutaneous electrical stimulation module;
when the sleep state data is changed from a quiet state to a light sleep state or a deep sleep state, stopping the electrical stimulation module;
and when the sleep state data is not changed, adjusting the working parameters of the transcranial electrical stimulation module.
Specifically, after the target user enters a quiet state from a waking state, the sleep state data of the target user is acquired at preset time intervals, and whether the sleep state data of the target user changes or not is judged. The sleep state data of the target user changes in the following situations:
1. the sleep state data changes from a quiet state to an awake state. This situation indicates that the target user is disturbed during sleep and a more effective stimulus is needed to help the target user re-enter the sleep state. Therefore, when the sleep state data is changed from a calm state to a waking state, the transcranial electrical stimulation module is stopped, and the transcranial electrical stimulation module which is more effective in promoting sleep is adopted;
2. the sleep state data is changed from a quiet state to a light sleep state or a deep sleep state. At the moment, the target user enters a sleep state and does not need external force to assist in sleeping any more, and the electric stimulation module can be stopped;
3. the sleep state data is unchanged. At this time, when the target user is in a calm state all the time and cannot enter a shallow sleep state or a deep sleep state, the target user may be helped to enter the shallow sleep state or the deep sleep state by adjusting working parameters of the transcranial electrical stimulation module because the current intensity or the frequency of the transcranial electrical stimulation module is not high enough.
According to the embodiment, different operations are adopted according to different change conditions of the sleep state of the target user, so that the sleep quality of the target user can be more effectively improved.
In one implementation mode, the transcutaneous electrical stimulation module comprises a forehead belt, wherein a plurality of air bags and micro air pumps which are in one-to-one correspondence with the air bags are arranged in the forehead belt; each air bag is provided with an electrical stimulation unit, and the air bags are used for supporting the electrical stimulation units to be attached to the forehead of the target user; the stopping the transcutaneous electrical stimulation module includes:
controlling each electrical stimulation unit to stop sending current;
air in the corresponding air bags is sucked out through the micro air pumps, so that the air bags collapse, and the electric stimulation units are not attached to the forehead of the target user any more.
