具体实施方式Detailed ways
如图1所示，一种睡眠诱导装置，包括：采集作用对象实时生理信号的生理信号采集模块100，接收与处理作用对象实时生理信号、当实时生理信号处于预设阈值范围时发出控制信号的睡眠深度监测模块200，获取作用对象不同睡眠参数相关的最佳频率的最佳频率获取模块300，根据控制信号以及最佳频率发出脉冲电磁场的睡眠诱导模块400，脉冲电磁场作用于作用对象以诱导进入控制信号对应的睡眠状态。As shown in FIG. 1 , a sleep inducing device includes: a physiological signal collecting module 100 that collects a real-time physiological signal of a working object, receives and processes a real-time physiological signal of the working object, and issues a control signal when the real-time physiological signal is within a preset threshold range. The sleep depth monitoring module 200 acquires an optimal frequency acquisition module 300 that applies an optimal frequency related to different sleep parameters of the target object, and a sleep induction module 400 that emits a pulsed electromagnetic field according to the control signal and the optimal frequency, and the pulsed electromagnetic field acts on the active object to induce entry. The sleep state corresponding to the control signal.
生理信号采集模块100与睡眠深度监测模块200连接，睡眠深度监测模块200以及最佳频率获取模块300分别与睡眠诱导模块400连接。The physiological signal acquisition module 100 is connected to the sleep depth monitoring module 200, and the sleep depth monitoring module 200 and the optimal frequency acquisition module 300 are respectively connected to the sleep inducing module 400.
生理信号采集模块100用于采集作用对象实时生理信号，生理信号采集模块100具体可以包括用于采集肌电生理信号的肌电采集模块、用于采集脉率生理信号的脉率采集模块以及用于采集体动生理信号的传感器模块，肌电采集模块、脉率采集模块以及传感器模块分别与睡眠深度监测模块连接。具体地，对于肌电生理信号：在觉醒时，肌电生理信号的幅度较大，随着睡眠程度加深，幅度减小；对于脉率生理信号，包括动脉搏动的频率、脉率变异性(PRV，Pulse  Rate Variability)。脉率的快慢受年龄、性别、运动和情绪等因素的影响。运动和情绪激动时，可使脉率增加，而休息、睡眠时则减慢。脉率变异性与心率变异性高度相关，可以反映自主神经活动，用以分析睡眠情况。对于体动生理信号：在觉醒时，体动生理信号大多较为明显和频繁，除了觉醒期外，其它时相期也可能存在偶尔的非明显体动行为，但与觉醒时相比，发生的频度较低，动作幅度也较小，可由此有效地区分出觉醒期与睡眠期。The physiological signal acquisition module 100 is configured to collect a real-time physiological signal of the active object, and the physiological signal acquisition module 100 may specifically include a myoelectric acquisition module for collecting the electrophysiological signal, a pulse rate acquisition module for collecting the pulse rate physiological signal, and The sensor module for collecting body motion physiological signals, the myoelectric acquisition module, the pulse rate acquisition module and the sensor module are respectively connected with the sleep depth monitoring module. Specifically, for the electrophysiological signal: when awakening, the amplitude of the electrophysiological signal is larger, and the amplitude decreases as the degree of sleep deepens; for the pulse rate physiological signal, including the frequency of the arterial pulsation, the pulse rate variability (PRV) , Pulse Rate Variability). The speed of the pulse rate is affected by factors such as age, gender, exercise and mood. When exercising and agitation, the pulse rate is increased, while rest and sleep are slowed down. Pulse rate variability is highly correlated with heart rate variability and can reflect autonomic activity to analyze sleep. For body motion physiological signals: when awakening, body and body physiological signals are mostly obvious and frequent. In addition to the awakening period, occasional non-obvious physical behavior may occur in other phases, but the frequency occurs when compared with awakening. The degree is lower and the range of motion is smaller, so that the awakening period and the sleep period can be effectively separated.
睡眠深度监测模块200用于接收与处理作用对象实时生理信号，当实时生理信号处于预设阈值范围时发出控制信号，调控睡眠诱导模块。该控制信号具有特定的模式(Pattern)，与具体的睡眠状态紧密相关。比如通过接收到的实时肌电生理信号、实时脉率生理信号以及实时体动生理信号，经过数字滤波、小波分解等处理之后，建模推导出作用对象的睡眠状态。对多个生理信号综合处理，可以提高对作用对象睡眠状况的监测精准度，以更好地进行后续睡眠诱导。当监测到作用对象处于某种觉醒状态，需要辅助睡眠时，发出与该觉醒状态相关的控制信号；当监测到作用对象处于睡眠状态时，发出控制信号关闭睡眠诱导模块。The sleep depth monitoring module 200 is configured to receive and process a real-time physiological signal of the active object, and issue a control signal when the real-time physiological signal is in a preset threshold range, and adjust the sleep inducing module. The control signal has a specific pattern that is closely related to the specific sleep state. For example, through the received real-time electrophysiological signals, real-time pulse rate physiological signals, and real-time physical and physiological signals, after digital filtering, wavelet decomposition, etc., the sleep state of the target object is derived by modeling. Comprehensive processing of multiple physiological signals can improve the monitoring accuracy of the sleeping condition of the active subject to better perform subsequent sleep induction. When it is detected that the active object is in a certain awakening state and needs to assist sleep, a control signal related to the awakening state is issued; when it is detected that the active object is in a sleep state, a control signal is issued to close the sleep inducing module.
最佳频率获取模块300用于获取作用对象不同睡眠参数相关的最佳频率，具体地，最佳频率获取模块用以搜索天线在目标区域敏感的频率段内的反射系数最小的频点，即最佳频率。最佳频率，指的是载波频率的最佳频率，与头是否离枕等睡眠参数有关。睡眠参数也包括心率参数、肌电参数、体动参数等等。个性化的控制信号，即模式(Pattern)，与清醒、浅睡、深睡等睡眠状态有关。与睡眠状态相关的不同模式(Pattern)的控制信号：睡眠状态可以划分为若干个，如三种清醒情景、三种浅睡情景和三种深睡情景。处在不同清醒情景下，采用不同模式的控制信号。同一种清醒情景，不同的作用对象的模式，也是不一样的。个性化的模式是后台通过分析对象的大数据，推导得出的，主要参数包括脉冲电磁场的强度、脉冲调制信号的频率、占空比、持续时间等等。The optimal frequency acquisition module 300 is configured to obtain an optimal frequency related to different sleep parameters of the target object. Specifically, the optimal frequency acquisition module is configured to search for a frequency point with the smallest reflection coefficient of the antenna in the frequency segment sensitive to the target area, that is, the most Good frequency. The optimal frequency refers to the optimal frequency of the carrier frequency, which is related to the sleep parameters such as whether the head is off the pillow. Sleep parameters also include heart rate parameters, myoelectric parameters, body motion parameters, and the like. The personalized control signal, the pattern, is related to sleep states such as waking, light sleep, and deep sleep. Different patterns of sleep signals related to the sleep state: The sleep state can be divided into several, such as three awake scenarios, three shallow sleep scenarios, and three deep sleep scenarios. In different awake scenarios, different modes of control signals are used. The same kind of lucid situation, the mode of different objects is also different. The personalized mode is derived from the analysis of the object's big data in the background. The main parameters include the intensity of the pulsed electromagnetic field, the frequency of the pulse modulation signal, the duty cycle, the duration, and so on.
大脑分为不同区域，不同区域负责不同的功能。当需要提高警觉度时，可通过刺激(即调制)苏醒区，该区包含蓝斑核(LC，Locus Coeruleus)等，提高该区细胞核团的极化与去极化频率，释放出更多诸如乙酰胆碱(Ach， Acetylcholine)的神经递质；如需促进睡眠，可通过刺激(即调制)下丘脑附近的细胞核团，如腹外侧视前核(VLPO，Ventrolateral preoptic nucleus)，使其更加活跃而释放出更多促进睡眠的神经递质，如γ-氨基丁酸等。不同功能区的工作频率是不一样的，对外在环境的响应也不相同。比如，脑电信号在熟睡时，其频率小于4Hz；浅睡时，其频率为4Hz-8Hz；放松状态时频率为8Hz-13Hz；觉醒时一般大于13Hz，且随着频率的升高，意识状态为越清醒状态。The brain is divided into different regions, and different regions are responsible for different functions. When it is necessary to increase the alertness, it can stimulate (ie, modulate) the wake-up zone, which contains the locus nucleus (LC, Locus Coeruleus), etc., to increase the polarization and depolarization frequency of the cell nuclei in the zone, releasing more such as A neurotransmitter of acetylcholine (Ach, Acetylcholine); if it is required to promote sleep, it can be released by stimulating (ie, modulating) a nuclear mass near the hypothalamus, such as the ventral lateral preoptic nucleus (VLPO, Ventrolateral preoptic nucleus). More neurotransmitters that promote sleep, such as gamma-aminobutyric acid. The operating frequency of different functional areas is different, and the response to the external environment is different. For example, when the EEG signal is asleep, its frequency is less than 4 Hz; when it is sleeping, its frequency is 4 Hz-8 Hz; when it is relaxed, the frequency is 8 Hz-13 Hz; when it is awake, it is generally greater than 13 Hz, and as the frequency increases, the state of consciousness The more awake the state is.
睡眠诱导模块400接收控制信号以及最佳频率，根据控制信号以及最佳频率产生脉冲电磁场，再将脉冲电磁场靶向作用于作用对象的目标区域，调节目标区域的工作频率。比如，将脉冲电磁场靶向作用于作用对象的下丘脑，使其更加活跃而释放出更多促进睡眠的神经递质，以诱导作用对象快速进入控制信号对应的睡眠状态。具体的，比如待测对象处在第一清醒情景，目标区域的目标频率≥15Hz，睡眠参数给出的最佳频率为5GHz，则睡眠诱导模块输出的脉冲电磁场可能是控制信号为1kHz、占空比为10％、峰值功率为40dBm、载波频率为5GHz的电磁场。通过靶向性的能量与信息传输，使目标区域的细胞核团的极化与去极化频率≥15Hz，释放出更多的促进睡眠的神经递质，以快速进入睡眠状态。目标区域的目标频率，需通过实验与专业的仪器，如EEG(electroencephalograph，脑电图描记器)设备、PET(Positron Emission Computed Tomography，正电子发射型计算机断层显像)仪器、fMRI(functional magnetic resonance imaging，功能性磁共振成像)仪器等，进行获取。一组控制信号，产生出一个特定的模式，以针对不同的情境和不同的作用对象。The sleep inducing module 400 receives the control signal and the optimal frequency, generates a pulsed electromagnetic field according to the control signal and the optimal frequency, and then targets the pulsed electromagnetic field to the target area of the active object to adjust the operating frequency of the target area. For example, the pulsed electromagnetic field is targeted to the hypothalamus of the subject, making it more active and releasing more neurotransmitters that promote sleep, so as to induce the subject to quickly enter the sleep state corresponding to the control signal. Specifically, if the object to be tested is in the first awake scenario, the target frequency of the target region is ≥15 Hz, and the optimal frequency given by the sleep parameter is 5 GHz, the pulse electromagnetic field output by the sleep inducing module may be a control signal of 1 kHz and duty. An electromagnetic field with a ratio of 10%, a peak power of 40 dBm, and a carrier frequency of 5 GHz. Through the targeted energy and information transmission, the polarization and depolarization frequency of the nuclear nucleus in the target region is ≥15Hz, releasing more sleep-promoting neurotransmitters to quickly enter the sleep state. The target frequency of the target area needs to pass experimental and professional instruments, such as EEG (electroencephalograph), PET (Positron Emission Computed Tomography) instrument, fMRI (functional magnetic resonance) Imaging, functional magnetic resonance imaging) instruments, etc., are acquired. A set of control signals that produce a specific pattern for different contexts and different objects of action.

The physiological signal collecting module 100 is connected to the sleep depth monitoring module 200, and the sleep depth monitoring module 200 and the most The good frequency acquisition module 300 is connected to the sleep inducing module 400, respectively. The physiological signal acquisition module 100 is configured to collect a real-time physiological signal of the active object, and the sleep depth monitoring module 200 is configured to receive and process a real-time physiological signal of the active object, and send a control signal when the real-time physiological signal is within a preset threshold range, and the optimal frequency acquisition module 300 The sleep inducing module 400 receives the control signal and the optimal frequency, and outputs a pulsed electromagnetic field according to the control signal and the optimal frequency. The pulsed electromagnetic field acts on the object of action, and guides the activity of the target area by targeting the target area of the target object, so as to induce the object to quickly enter the sleep state corresponding to the control signal. The sleep inducing device can effectively improve the quality of sleep and solve the problem of sleep disorders.
在一个实施例中，睡眠诱导装置中脉冲电磁场的频率为目标区域敏感的频率段内的频率，脉冲电磁场的频率为最佳频率获取模块获取到的最佳频率。脉冲电磁场具体的频率值，可以由最佳频率获取模块根据头部离枕等睡眠参数选取。比如某种清醒状态下，目标区域的目标频率≥15Hz，最佳频率获取模块获取到作用对象不同睡眠参数相关的最佳频率为5GHz，那么脉冲电磁场为控制信号为1kHz、占空比为10％、峰值功率为40dBm、载波频率为5GHz的电磁场。当脉冲电磁场的半波长与目标区域的尺寸相近相关时，脉冲电磁场的能量与信息可以最大程度地传递给目标区域，实现‘共振效应’。相近相关，具体指半波长或半波长的整数倍，大约与目标区域的尺寸一致。根据需要改变脉冲电磁场的调制频率，以引导作用对象目标区域的实际工作频率，即改变神经细胞的极化与去极化频率，进而强化目标区域的功能。考虑到单个脉冲对目标区域的极化与去极化频率影响非常小。因此，若要将目标区域的极化与去极化频率提高1Hz，需要n个脉冲。一般的，n在40～200之间。如需提高5Hz，则相关的调制频率为200Hz～1000Hz之间，具体选取因睡眠情境、作用对象等参数而不同。In one embodiment, the frequency of the pulsed electromagnetic field in the sleep inducing device is a frequency within a frequency segment that is sensitive to the target region, and the frequency of the pulsed electromagnetic field is the optimal frequency obtained by the optimal frequency acquisition module. The specific frequency value of the pulsed electromagnetic field can be selected by the optimal frequency acquisition module according to sleep parameters such as head occlusion. For example, in a certain awake state, the target frequency of the target area is ≥15 Hz, and the optimal frequency acquisition module obtains the optimal frequency related to different sleep parameters of the active object is 5 GHz, then the pulse electromagnetic field has a control signal of 1 kHz and a duty ratio of 10%. An electromagnetic field with a peak power of 40 dBm and a carrier frequency of 5 GHz. When the half wavelength of the pulsed electromagnetic field is closely related to the size of the target region, the energy and information of the pulsed electromagnetic field can be transmitted to the target region to the maximum extent, achieving a 'resonance effect'. Similar correlation, specifically an integer multiple of a half wavelength or a half wavelength, approximately the same as the size of the target area. The modulation frequency of the pulsed electromagnetic field is changed as needed to guide the actual working frequency of the target region of the target object, that is, to change the polarization and depolarization frequency of the nerve cells, thereby enhancing the function of the target region. Considering that the influence of a single pulse on the polarization and depolarization frequency of the target region is very small. Therefore, to increase the polarization and depolarization frequency of the target region by 1 Hz, n pulses are required. In general, n is between 40 and 200. If you need to increase 5Hz, the relevant modulation frequency is between 200Hz and 1000Hz. The specific selection is different due to parameters such as sleep situation and target object.
在一个实施例中，睡眠诱导装置中的睡眠深度监测模块包括接收与处理作用对象实时生理信号、当实时生理信号处于预设阈值范围时发出控制信号的控制器。比如控制器接收实时肌电生理信号、实时脉率生理信号以及实时体动生理信号，将实时肌电生理信号、实时脉率生理信号以及实时体动生理信号分别与对应的预设阈值范围进行比较，得到作用对象处于觉醒期或睡眠期。通过三个生理信号的实时值与预设阈值进行比较，来得到作用对象的睡眠状况，这样可以提高对作用对象睡眠状况的监测精准度，以更好地进行后续睡眠诱导。控制器在监测到作用对象处于觉醒期，需要辅助睡眠时，发出表征睡眠的控制信号；在监测到作用对象处于睡眠期时，需要辅助清醒时，发出表征觉醒的控制信号。更为具体地，控制器可以采用STM32系列控制芯片，比如STM32F413CGU6控制芯片。STM32F413CGU6控制芯片基于32位Cortex-M4 架构内核，内置闪存、RAM(Random Access Memory，随机存取存储器)、模数转换器、定时器/计数器和USART(Universal Synchronous/Asynchronous Receiver/Transmitter，通用同步/异步串行接收/发送器)通讯口等多种资源，时钟频率最高可达100MHz。合理地选择高性能的控制器，有利于***集成，便于产品小型化；同时，可提高监测的准确度和实时性。In one embodiment, the sleep depth monitoring module in the sleep inducing device includes a controller that receives and processes a real-time physiological signal of the active subject, and issues a control signal when the real-time physiological signal is within a predetermined threshold range. For example, the controller receives real-time electromyographic signals, real-time pulse rate physiological signals, and real-time physical and physiological signals, and compares real-time electrophysiological signals, real-time pulse rate physiological signals, and real-time physical and physiological signals with corresponding preset threshold ranges. , the target is in the awakening period or sleep period. By comparing the real-time values of the three physiological signals with the preset thresholds, the sleep state of the target object is obtained, which can improve the monitoring accuracy of the sleeping condition of the working object, so as to better perform subsequent sleep induction. When the controller detects that the active object is in the awakening period and needs assisted sleep, it sends a control signal indicating sleep; when it is detected that the active subject is in the sleep period, when the auxiliary awake is needed, a control signal indicating the awakening is issued. More specifically, the controller can use STM32 series control chips, such as the STM32F413CGU6 control chip. The STM32F413CGU6 control chip is based on a 32-bit Cortex-M4 architecture core with built-in flash memory, RAM (Random Access Memory), analog-to-digital converter, timer/counter and USART (Universal Synchronous/Asynchronous Receiver/Transmitter). Asynchronous serial receiver/transmitter) Communication port and other resources, the clock frequency can be up to 100MHz. Reasonable selection of high-performance controllers facilitates system integration and facilitates product miniaturization; at the same time, it improves monitoring accuracy and real-time performance.

The interaction module is connected to the controller, and the interaction module is used to facilitate user operations. Specifically, the interaction module may include a wearing detection module, a display module, and a switch module. The wearing detection module sends an acquisition start signal to the controller when detecting that the user is wearing well, and the controller sends a command to the physiological signal acquisition module to automatically start the data collection function; and when detecting that the user is not wearing properly, for example, through the infrared sensor Or the real-time signal detected by the capacitive sensor is not in the preset threshold range, then an acquisition off signal is sent to the controller, the controller does not start the data acquisition function, and outputs an incorrect prompt to the display module. The display module can display the current time, the connection status, the battery power, the sleep induction device working state, the subject's sleep state, the wearing state, and the like. The display module may include an OLED (Organic Light-Emitting Diode) display, and the OLED is also called an organic electro-laser display, an organic light-emitting semiconductor, and the OLED display has self-luminous, wide viewing angle, almost infinite contrast, and low Power consumption, high reaction speed and other advantages. The switch module can include a push button switch. For example, the OLED display can be activated or switched by short pressing the button switch, and the sleep inducing device can be activated or deactivated by long pressing the button switch. Specifically, the short press may be less than 2 seconds, and the long press may be greater than or equal to 3 seconds. The display module is connected to the controller to visually display the output information of the controller. The display module includes a display driving circuit and a display, the controller is connected to the driving circuit, and the driving circuit is connected to the display. For example, the controller receives the acquisition off signal sent by the wearing detection module, and outputs an instruction to wear the incorrect prompt information. After receiving the instruction, the driving circuit drives the display to display the “not properly worn” interface.

For example, the control signal received by the control chip is a control signal for characterizing sleep, and the target frequency of the target area of the received object is 12 Hz. The control chip issues a pulsed electromagnetic field generation command that causes the target region to enter the target state based on the received control signal indicative of sleep and the target frequency of the target region of the active object. The pulsed electromagnetic field generated according to the pulse electromagnetic field generating instruction acts on the target area of the active object, and guides the target area into the target state by targeting the target area to induce the object to enter the sleep state.
