Due to the sports characteristics and special working environment of cars, people's demand for high-quality sleep is also growing. Among them, office workers are very eager to get enough rest while busy at work to improve their work efficiency in the afternoon. On the other hand, for people who drive for a long time, if they can maintain a short and good rest in the middle of the journey, it can also improve the safety of drivers and passengers.

[0070] The sleep aid switch button 1 is connected to the controller assembly 2 and is used to start the switch signal with one button;

[0071] The output end of the controller assembly 2 is respectively connected to a brain wave detection component 3, a seat posture adjustment component 4, a natural breathing component 5, a water molecule atomization component 6 and a noise interference elimination component 7 for sending control instructions;

[0072] The output end of the brain wave detection component 3 is connected to a three-in-one control component 8, which is used to collect weak electrical signals from the cerebral cortex and analyze different brain wave characteristic signals; a seat posture adjustment component 4, which is used to store and adjust the seat state; a natural breathing component 5, which is used to detect and control the oxygen concentration; a water molecule atomization component 6, which is used to control the atomization amount of water molecules according to humidity data; a noise interference elimination component 7, which is used to block the propagation of noise; a three-in-one control component 8, which is used to adjust music, air conditioning and lighting.

[0073] Specifically, the sleep aid switch button 1 is a manual or automatic button installed in the vehicle cockpit. As the start button of the entire control system, it can start the entire control system to improve the sleeping environment with one click through the electrical connection with the controller assembly 2. It is convenient to operate and can improve the sleep quality of the sleeper in the cockpit with one click.

[0074] The controller assembly 2 serves as the core of the entire control system. The input end is used to receive the switch information transmitted by the sleep aid switch button 1, and the output end is electrically connected to the brain wave detection component 3, the seat posture adjustment component 4, the natural breathing component 5, the water molecule atomization component 6 and the noise interference elimination component to transmit control instructions.

[0075] The input end of the brain wave detection component 3 is connected to the controller assembly 2 and the cerebral cortex. When receiving the control signal of the controller assembly 2, the weak signal of the cerebral cortex is collected for processing and analysis. On the one hand, the imaging file is displayed and output. On the other hand, the brain wave waveform can be defined as falling asleep, latent sleep, moderate sleep and deep sleep, so as to match the music, air conditioning and lighting that are most suitable for the current sleep state according to the big data network center 9, and send them to the three-in-one control component 8 for three-in-one control of music, air conditioning and lighting.

[0076] The input end of the seat posture adjustment component 4 is connected to the controller assembly 2. The seat posture adjustment component 4 includes a memory part on the one hand, which can directly adjust the position of the seat back, seat cushion, and legs when in use; on the other hand, it includes a driving part, which can drive the pitch angle of the backrest, the front and rear movement of the seat cushion, and the tilt angle of the leg support. At the same time, it can also drive the heater in cold seasons to heat the above-mentioned positions.

[0077] The input end of the natural breathing component 5 is connected to the controller assembly 2. After receiving the control signal, the air can be released into the cockpit after filtering large particles and dust through the internal circulation pump, and the oxygen content in the cockpit can be controlled after detection by the sensor. In an oxygen-rich environment with high oxygen content, people have better sleep quality.

[0078] The input end of the water molecule atomization component 6 is connected to the controller assembly 2. After receiving the control signal, it controls and adjusts the atomization amount in the cockpit through the internal water tank and the atomization sheet to help improve sleep quality.

[0084] Specifically, the input end of the electrode module 31 is connected to the controller assembly 2. After receiving the control signal of the controller assembly 2, the collection electrode 311 in the electrode module 31 can be made into a head ring or a head cover type. When resting in the cockpit, the collection electrode 311 is fixed around the scalp and the electrical signal is collected. The signal amplifier 312 and the digital conversion subassembly 313 are amplified and converted in turn, and then transmitted to the signal adjustment module 32 for filtering and adjustment processing. Finally, the data analysis storage module 33 performs data analysis based on the four waveforms (α wave, β wave, θ wave and δ wave) to infer four sleep qualities (falling asleep, latent sleep, moderate sleep and deep sleep), and the big data network center 9 matches the influencing factors related to sleep quality and transmits them to the three-in-one control component 8 through the three-in-one controller 36 to control the internal environment of the cockpit. The data transmitted from the data analysis storage module 33 to the big data network center 9 will also be directly exported to the brain wave imaging file through the output module 34, which is conducive to medical examination when necessary, and is dynamically displayed on the output display terminal 35.

[0085] It should be noted that the frequency and amplitude ranges of the four waveforms are:

When the driver only needs to automatically adjust the seat posture, the custom seat module 432 can send a signal to the two-in-one controller 41, and then the two-in-one controller 41 adjusts the seat through the connected seat drive module 42. Secondly, the seat drive module 42 is connected to the sensor subassembly 433 and the memory chip 431, and the memory chip 431 is connected to the two-in-one controller 41 to form a loop.

[0106] In an embodiment of the present invention, Figure 6 As shown, the water molecule atomization assembly 6 includes a second start / stop button 61 and a second sub-controller 62 connected to each other;

[0107] The second sub-controller 62 is respectively connected to an oscillating circuit 63, a fan 64 and a mist control circuit 65, the oscillating circuit 63 and the mist control circuit 65 are both connected to an atomizing sheet 66, the second start / stop button 61 is connected to a water level detection circuit 67; the fan 64, the atomizing sheet 66 and the water level detection circuit 67 are all arranged in a water storage tank 68;

[0108] The water storage tank 68 is provided with a water inlet pipe 681, a water discharge pipe 682 and a mist discharge pipe 683 at the shell;

[0109] The second sub-controller 62 is connected to the controller assembly 2 , and the demisting pipe 683 is connected to the cockpit. A humidity sensor 69 is also provided in the cockpit, and the humidity sensor 69 is also connected to the big data network center 9 .

[0110] Specifically, the water molecule atomization assembly 6 includes a second sub-controller 62 whose input end is connected to the controller assembly 2, which is used to receive signals from the controller assembly 2 and send control instructions to the oscillating circuit 63 and the mist control circuit 65. The oscillating circuit 63 and the mist control circuit 65 are both connected to the atomizing sheet 66 in the water storage tank 68. The water mist generated by the electrolysis of water molecules by the atomizing sheet 66 enters the cockpit through the mist exhaust pipe 683. In addition, the second sub-controller 62 is also connected to the second start-stop button 61, which is connected to the water level detection circuit 67. The driver can actively or passively operate the second sub-controller 62; when the mist is not needed or the water volume in the water storage tank 68 exceeds the standard, the second sub-controller 62 can be terminated, thereby terminating the operation of the oscillating circuit 63 and the mist control circuit 65.

[0111] Among them, the fan 64, the atomizer 66 and the water level detection circuit 67 are all arranged in the water tank 68. The shell of the water tank 68 is provided with a water inlet pipe 681, a drainage pipe 682 and a mist exhaust pipe 683, which are used for water intake, drainage and mist exhaust respectively.

[0112] In addition, a humidity sensor 69 is provided in the cockpit, and the humidity sensor 69 is also connected to the big data network center 9 for data matching, so as to obtain the optimal sleepiness humidity information and send it back to the controller assembly 2 and the second sub-controller 62 in turn, so as to adjust the atomization amount of water molecules most suitable for sleep this time.

[0113] In an embodiment of the present invention, Figure 7 As shown, the noise interference elimination component 7 includes a third start / stop button 71 and a third sub-controller 72 connected to each other;

[0114] The third sub-controller 72 is connected to a muffler 73, and the third sub-controller 72 is connected to the controller assembly 2;

[0115] The noise interference elimination assembly 7 further includes a sound absorbing layer 74 arranged in the cockpit.

[0116] Specifically, the noise interference elimination component 7 includes a third sub-controller 72 whose input end is connected to the controller assembly 2, which is used to receive the signal of the controller assembly 2 and send a control instruction to the muffler 73; the mufflers are respectively arranged at the engine, radiator, and air-conditioning compressor to cut off the generation of noise at the signal source. Among them, the third sub-controller 72 is connected to the third sub-controller 72 separately, and the driver can actively run or stop the third sub-controller 72. In addition, the noise interference elimination component 7 also includes a sound absorbing layer 74 arranged inside or around the cockpit.

[0117] It should be noted that the muffler can also be placed at other noise sources in the car to reduce noise.

[0118] It should be noted that the sound absorbing layer 74 may be a high-efficiency sound absorbing material other than ceramic microbeads or carbon fiber composite materials, so as to achieve the effect of reducing noise and preventing noise from affecting sleep.

[0119] The present invention also provides a control method for a control system for optimizing sleep quality in a cockpit, such as Figure 2 As shown:

[0120] Step 1: Press the sleep aid switch button 1 to release the switch signal to the controller assembly 2;

[0121] Step 2: The controller assembly 2 filters, amplifies and modulates the switch signal to obtain an electrical signal, and calculates the control signal through a preset PID control method and parameters;

[0122] Specifically, the controller assembly 2 has a built-in signal processing circuit (including a filter, an amplifier, a modulator) and a control algorithm. The signal processing circuit filters, amplifies, and modulates the switch signal released by the sleep-aid switch button 1 to obtain an electrical signal. In addition, the pre-processed electrical signal is used to calculate a control signal through a preset proportional-integral-differential (PID) control algorithm and parameters.

[0123] Step 3, after the brain wave detection component 3 receives the control signal, it drives the electrode to collect the weak electrical signal of the cerebral cortex, and calculates the signal output value after filtering and modulating the weak electrical signal for terminal display; at the same time, after obtaining one of the α wave, β wave, θ wave and δ wave according to the frequency and amplitude range, the sleep state of the resting person is judged, and then the best sleep condition is selected to control the three-in-one control component 8 to adjust the music, air conditioning and lighting in the cockpit;

[0124] The seat posture adjustment component 4, the natural breathing component 5, the water molecule atomization component 6 and the noise interference elimination component 7 also receive the control signal in step 2 at this time and control the seat state, oxygen concentration, water molecule atomization amount and noise reduction in the cockpit respectively.

[0125] Step 3 The specific steps are as follows:

[0126] Step 3.1, the collection electrode 311 receives the control signal transmitted by the controller assembly 2, and starts the electrode to collect weak electrical signals around the human scalp; the weak electrical signal is transmitted to the signal amplifier 312 for amplification to obtain an amplified electrical signal; the amplified electrical signal is then filtered and processed by the digital conversion subassembly 313 and converted into a digital signal and transmitted to the signal conditioning module 32;

[0127] Step 3.2, the signal conditioning module 32 has a built-in signal filtering algorithm, and then uses the frequency characteristics of the signal to modulate the signal by introducing impedance to obtain a frequency modulated signal;

[0128] Step 3.2.1, the specific filtering process is to represent the signal in the time domain, that is, the time domain signal x(t);

[0129] Next, the signal is converted from the time domain to the frequency domain through the Fourier transform method, which is expressed as the superposition of sine waves of different frequencies; the Fourier transform formula is:

[0130] X(f)=∫x(t)e^(-j2Πft)dt(1)

[0131] Among them, X(f) is the frequency domain signal, x(t) is the time domain signal, f is the frequency, t is the time, and j is the imaginary part;

[0132] Then, according to the signal processing requirements, the components are selectively retained or removed, and the output result after filtering is calculated as follows:

[0133] Y(n)=a*X(n)+(1-a)*Y(n-1)+a*(X(n)-Y(n-1))(2)

[0134] Among them, Y(n) is the current filtering result, X(n) is the current sampling value, a is the filtering coefficient, and Y(n-1) is the previous filtering result;

[0135] After frequency selection, the signal is converted from the frequency domain back to the time domain to obtain the filtered signal, which needs to be inverse Fourier transform. The formula is:

[0136] x(t)=(1 / 2Π)∫X(f)e^(j2Πft)df(3);

[0137] Step 3.2.2, applying the filtered signal x(t) obtained in step 3.1.1 to the carrier signal (high frequency signal), carrying the modulated signal by changing the amplitude, phase or frequency of the carrier, and then transforming it into a signal suitable for channel transmission;

[0138] The present invention adopts a frequency adjustment method, and its signal expression is:

[0139] sFM(t)=Ac*cos[2*Π*(fc+Δf*x(t)t+ρ)(4)

[0140] Where sFM(t) is the frequency modulated signal, Ac is the carrier amplitude, fc is the carrier frequency, Δf is the frequency offset, x(t) is the low frequency signal, ρ is the initial phase, and t is the signal transmission time;

[0141] Step 3.3, after the data analysis storage module 33 analyzes one of the waveforms of α wave, β wave, θ wave and δ wave according to the above final signal, the sleep state of the resting person is defined as one of falling asleep, latent sleep, moderate sleep and deep sleep; then, in combination with the big data network center 9, the influencing factors related to sleep quality are matched, and the best sleep condition is selected to control the three-in-one control component 8 to adjust the music, air conditioning and lighting in the cockpit;

[0142] At the same time, the data analysis and storage module 33 will directly export the EEG imaging file through the output module 34, which is beneficial for medical examination when necessary, and dynamically display it to the output display terminal 35;

[0143] Step 3.4, the seat posture adjustment component 4, the natural breathing component 5, the water molecule atomization component 6 and the noise interference elimination component 7 also receive the control signal in step 2 at this time and control the seat status, oxygen concentration, water molecule atomization amount and noise reduction in the cockpit respectively.
