[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] The present application provides a fatigue intervention device that combines sound, light, and electromagnetics. In an exemplary embodiment, Figure 1 As shown, it includes: a main control module, an acoustic stimulation module, a light stimulation module, an electrical stimulation module and a magnetic stimulation module; the main control module is used to analyze the fatigue state according to the acquired human physiological signals, control the combination of any one or more modules among the acoustic stimulation module, the light stimulation module, the electrical stimulation module and the magnetic stimulation module, and perform fatigue intervention on the user by a combination of acoustic, light, electrical and magnetic stimulation means.

[0034] The acoustic stimulation module is used to adjust the frequency difference between the left and right channel audio according to the control of the main control module, and use acoustic stimulation to intervene in the fatigue of the user; the optical stimulation module is used to adjust the illumination intensity of the infrared light according to the control of the main control module, and use optical stimulation to intervene in the fatigue of the user; the electrical stimulation module is used to adjust the electrical stimulation intensity of the electrode sheet according to the control of the main control module, and use electrical stimulation to intervene in the fatigue of the user; the magnetic stimulation module is used to adjust the intensity of the generated magnetic field according to the control of the main control module, and use magnetic stimulation to intervene in the fatigue of the user.

[0035] Specifically in this embodiment, Figure 2 As shown, the main control module includes: a physiological signal acquisition unit, a fatigue state analysis unit and an intervention means determination unit. The physiological signal acquisition unit is used to acquire real-time human physiological signals and send the human physiological signals to the fatigue state analysis unit. The fatigue state analysis unit is used to analyze the human physiological signals and determine the user's fatigue state. The intervention means determination unit is used to determine the intervention means to be taken according to the user's fatigue state.

[0036] As an example, after analyzing the collected human physiological signals, the main control module drives the four stimulation modules of light, magnetism, sound, and electricity as needed to stimulate different parts of the human body to relieve fatigue and help sleep, and can also improve cognitive level to a certain extent. In a possible implementation, the human body's electrocardiogram signals are collected, and the heart rate variability is calculated to analyze the user's fatigue state.

[0037] In a further limited embodiment, the main control module further includes: an acoustic stimulation control unit, a light stimulation control unit, an electrical stimulation control unit and a magnetic stimulation control unit.

[0038] An acoustic stimulation control unit is used to adjust the acoustic stimulation instructions issued according to the fatigue state of the user when the intervention means includes acoustic stimulation. A light stimulation control unit is used to adjust the light stimulation instructions issued according to the fatigue state of the user when the intervention means includes light stimulation. An electrical stimulation control unit is used to adjust the electrical stimulation instructions issued according to the fatigue state of the user when the intervention means includes electrical stimulation. A magnetic stimulation control unit is used to adjust the magnetic stimulation instructions issued according to the fatigue state of the user when the intervention means includes magnetic stimulation.

[0039] In this embodiment, the sound stimulation instruction is a fixed-length binary data, which is used to control the switching / playing of music tracks and adjust the volume; the sound stimulation instruction includes a 2-byte header, a 1-byte command line, a 1-byte data length, a 6-byte valid data segment and a 2-byte tail. The light stimulation instruction, the electrical stimulation instruction and the magnetic stimulation instruction are all PWM signals; the duty cycle of the PWM signal is changed by the main control module to obtain an analog voltage signal simulated according to the digital signal output. The PWM signal can be obtained by changing the duty cycle of the PWM square wave output by the I / O port of the main control module, thereby obtaining an analog voltage signal simulated using a digital signal. The change in the duty cycle means that the proportion of the high level in the entire signal cycle will change. As the duty cycle increases, the output energy will increase accordingly, and the average voltage value obtained by the resistor-capacitor conversion circuit will increase. As the duty cycle decreases, the voltage average value of the output voltage signal will decrease, and the average voltage value obtained by the resistor-capacitor conversion circuit will also decrease. At a certain frequency, different output analog voltages can be obtained by different duty cycles. The schematic diagram of equivalent voltage values ​​at the same frequency and different duty cycles is as follows. Figure 3 shown.

[0040] Specifically in this embodiment, Figure 4 As shown, the sound stimulation module includes a sound stimulation circuit and headphones; the sound stimulation circuit is connected to the sound stimulation control unit and the headphones respectively; the sound stimulation circuit is used to adjust the frequency difference between the left and right channel audio according to the sound stimulation instruction output by the sound stimulation control unit, and to provide sound stimulation to the user through the headphones. After receiving the sound stimulation instruction sent by the sound stimulation control unit of the main control module, the sound stimulation circuit decodes, filters and amplifies it to drive the headphones, thereby adjusting the frequency difference of the audio heard by the left and right ears.

[0041] The light stimulation module includes a light stimulation circuit and a light emitter; the light stimulation circuit is connected to the light stimulation control unit and the light emitter respectively; the light stimulation circuit is used to adjust the illumination intensity of the infrared light according to the light stimulation instruction output by the light stimulation control unit, and perform light stimulation on the user through the light emitter. In this embodiment, the light stimulation module affects the catalytic efficiency of cytochrome C oxidase (CCO) in neurons by adjusting the illumination intensity of the infrared light emitted by the light emitter, and can catalyze oxygen utilization to produce aerobic energy, promote the efficiency of synthesizing adenosine triphosphate (ATP) in the mitochondrial respiratory chain reaction, thereby regulating the respiration of mitochondria in neurons and improving cognitive function.

[0042] Specifically, the light stimulation circuit receives the PWM signal sent by the light stimulation control unit of the main control module, and connects it to one end of the light emitter after amplification, and the other end of the light emitter is connected to the +5V voltage. The light stimulation control unit adjusts the duty cycle of the output PWM signal to adjust the voltage applied to both ends of the light emitter to adjust the intensity of the emitted infrared light, thereby changing the wavelength of the emitted infrared light. The light emitter applies the light stimulation signal to the human body according to the light intensity.

[0043] As an alternative solution, the fatigue intervention method of the light stimulation module can also introduce other wavelengths of light, such as blue light therapy is used to treat seasonal affective disorder and sleep disorders, but light therapy usually targets mental health problems rather than direct physical fatigue. Existing devices on the market, such as the KRS-1 red light therapy device, achieve pain relief and improve blood circulation by emitting red light of a specific wavelength; transcranial magnetic stimulation (TMS) devices, which activate neural networks in the brain by generating magnetic fields, have been used to treat depression and other neuropsychiatric diseases. However, its single mode of action cannot provide a full range of intervention solutions. The fatigue intervention device proposed in this application provides a comprehensive and personalized solution through a multimodal stimulation method, which is more effective than a single stimulation method. The device can also provide customized intervention solutions for different individuals and fatigue types, increasing its flexibility and effectiveness in practical applications.

[0044] The electric stimulation module includes an electric stimulation circuit and an electrode patch; the electric stimulation circuit is connected to the electric stimulation control unit and the electrode patch respectively; the electric stimulation circuit is used to adjust the electric stimulation intensity of the electrode patch according to the electric stimulation instruction output by the electric stimulation control unit, and electrically stimulate the user through the electrode patch. Specifically in this embodiment, the electrode patch includes an anode patch and a cathode patch; the anode patch and the cathode patch are respectively located on the left and right foreheads of the user; the anode patch acts on the left forehead to increase the excitability of the user's cerebral cortex, improve learning ability and memory ability, and relieve fatigue; the cathode patch acts on the right forehead to reduce the excitability of the user's cerebral cortex and produce a sleep-aiding effect. The specific position of the electrode patch is to connect a conductive rubber electrode patch to the anode end and the cathode end of the load resistor. The function of the electrode patch is to apply electrical signals to the human body. The action position is a certain position to the left and right of the FPZ point position on the forehead central axis.

[0045] In another exemplary embodiment of the present application, the electrical stimulation circuit adjusts the output current by changing the voltage applied to both ends of the electrode patch, and the output current is output after passing through a comparison circuit with the standard current to ensure that the output current is less than or equal to the standard current. The electrical stimulation circuit receives the PWM signal output by the electrical stimulation control unit of the main control module, amplifies the current to a certain range through an amplifier circuit, and then passes it through a comparison circuit with the standard current, and then sends it to the electrode patch; the output current can be adjusted by changing the voltage applied to both ends of the electrode patch, and the output current is output after passing through a comparison circuit with the standard current to ensure that the output current is less than or equal to the standard current.

[0046] The magnetic stimulation module includes a magnetic stimulation circuit and a magnetic induction coil; the magnetic stimulation circuit is connected to the magnetic stimulation control unit and the magnetic induction coil respectively; the magnetic stimulation circuit is used to adjust the intensity of the generated magnetic field according to the magnetic stimulation instruction output by the magnetic stimulation control unit, and perform magnetic stimulation on the user through the magnetic induction coil. In this embodiment, the magnetic field output by the magnetic stimulation module through the magnetic induction coil can penetrate the user's skull and induce a weak current in the neurons of the cerebral cortex, causing the neurons to depolarize and generate action potentials. Transcranial magnetic stimulation of different frequencies has different effects. High-frequency TMS (usually ≥5 Hz) is usually used to increase the excitability of the cerebral cortex, while low-frequency TMS (usually ≤1 Hz) is used to reduce excitability.

[0047] The magnetic stimulation circuit receives the PWM signal sent by the magnetic stimulation control unit of the main control module, and after amplification, it is connected to one end of the magnetic induction coil, and the other end of the magnetic induction coil is connected to the +5V voltage. By adjusting the duty cycle of the PWM signal, the voltage level at the output end of the magnetic induction coil can be changed, thereby changing the magnetic induction intensity of the magnetic induction coil. The higher the duty cycle, the higher the average voltage of the coil, the stronger the magnetic induction intensity, and vice versa, the weaker it is, thereby adjusting the generated magnetic field intensity. The magnetic induction coil applies the magnetic stimulation signal to the human body according to the magnetic stimulation intensity.
