Description

Technical Field

[0001] The present invention belongs to the technical field of wireless communications and relates to a signal reception quality enhancement auxiliary system based on millimeter wave communication equipment. Background Art

[0002] Millimeter-wave communication equipment, due to its high bandwidth, is widely used in scenarios such as 5G base stations and automotive radars. However, in complex environments, it faces signal attenuation issues caused by multipath fading, mechanical vibration, and temperature and humidity interference. When deployed on mobile platforms or in high-humidity environments, the signal-to-noise ratio (SNR) of the received signal can be significantly degraded due to phenomena such as receiver directivity deviation, electromagnetic field disturbance caused by cooling airflow, and signal scattering exacerbated by water vapor adsorption. Existing technologies mitigate these issues through hardware reinforcement and algorithmic filtering, such as using mechanical vibration damping brackets to suppress vibration or using digital signal processing to compensate for multipath effects.

[0003] Traditional solutions employ mechanically stabilized structures that absorb vibration energy by adding damping elements, but this fails to eliminate the impact of high-frequency microvibrations on millimeter-wave phase. Active cooling utilizes fans for forced convection, but the alternating magnetic fields generated by rotating blades can interfere with high-frequency signal demodulation. Environmental control systems employ sealed cavities to isolate moisture, hindering the smooth transmission and reception of millimeter-wave signals. While signal processing algorithms can dynamically balance multipath fading, response delays can render compensation ineffective in scenarios involving sudden strong vibrations or rapid temperature changes.

[0004] To address the above issues, when multiple interference sources occur simultaneously, the compensation effects of each independent module cancel each other out; for example, the displacement of the vibration reduction structure blocks the heat dissipation duct, and the forced heat dissipation airflow exacerbates the vibration of the equipment, forming a negative cycle. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a signal reception quality enhancement auxiliary system based on millimeter wave communication equipment.

[0006] A signal reception quality enhancement auxiliary system based on millimeter wave communication equipment, comprising:

[0007] The rotating scanning module drives the receiving head to continuously rotate and scan and capture the millimeter wave signals reflected by the environment, generating a multi-directional composite signal stream;

[0013] The guidance feedback module is used to control the LED aperture to display the color gradient according to the intensity change of the collaborative enhancement signal, and generate visual operation guidance.

[0014] A further embodiment of the present invention generates a multi-directional composite signal stream, comprising the following steps:

[0015] A micro motor is installed inside the millimeter wave communication device. The output shaft of the micro motor is directly connected to the rotating base of the millimeter wave receiving head. When the millimeter wave communication device is powered on, the micro motor drives the receiving head to rotate and scan at a constant speed.

[0016] The waveguide groove on the surface of the device's metal shell begins to capture the millimeter wave signals reflected from the environment;

[0017] The rotating receiving head continuously receives direct waves from the front and reflected waves converged through the waveguide groove, forming a spatial phase matching relationship that depends on the rotation position of the receiving head and the waveguide groove pattern. The two types of signals are superimposed in the high-frequency circuit inside the receiving head to form a mixed waveform containing multi-path information, and the output is a multi-directional composite signal stream.

[0018] A further solution of the present invention is to provide a waveguide groove on the surface of the metal housing of the device, comprising the following steps:

[0019] A waveguide groove is a continuous wavy groove pattern formed on the surface of the metal shell of the device by laser etching. The wave period of the waveguide groove is set to N times the wavelength of the millimeter wave.

[0020] The depth of the waveguide trough and the wave period are set based on the contrast experiment of the reflected wave enhancement of different trough depth-period combinations;

[0021] The electromagnetic field modulation effect of the metal surface corrugations is utilized to force the environmental reflected waves to dynamically converge toward the rotating receiving head.

[0022] A further solution of the present invention generates a dynamic interference parameter set, comprising the following steps:

[0023] Piezoelectric ceramic sensors are attached to the four corners of the device's metal casing. When the device is vibrated by external force, the crystal plate of the piezoelectric ceramic sensor generates a microcurrent due to deformation, and the vibration current signal output by the piezoelectric ceramic sensor is obtained;

[0024] Real-time detection of ambient temperature and relative humidity;

[0025] The cooling fan motor power supply line is connected in series with a Hall ammeter, which measures the driving current and converts it into the real-time speed of the fan;

[0026] The equipment vibration intensity, ambient temperature and relative humidity collected by the integrated temperature and humidity sensor, and cooling fan speed are aligned according to timestamps to generate a dynamic interference parameter set containing standardized parameters.

[0027] A further solution of the present invention is to detect the ambient temperature and relative humidity in real time, comprising the following steps:

[0029] The probe of the integrated temperature and humidity sensor is directly exposed to the air to detect the ambient temperature and relative humidity in real time.

[0030] A further solution of the present invention is to output an anti-vibration stabilization signal, comprising the following steps:

[0031] The dynamic interference parameter set extracts the equipment vibration intensity data, which represents the acceleration value converted by the piezoelectric ceramic sensor;

[0032] generating a vibration-cancelling current for reverse vibration according to a preset acceleration current mapping table;

[0033] The vibration-cancelling current is transmitted to the electromagnetic brake on the device mainboard to generate a reverse mechanical force, which simultaneously transmits the same vibration-cancelling current signal to the micro-motor of the receiving head rotation mechanism, triggering the receiving head to deflect in the opposite direction of the vibration;

[0034] The deflected receiving head continuously receives the multi-directional composite signal flow converged by the waveguide slot, compensates for the signal phase shift caused by vibration, and outputs a vibration-resistant and stable signal.

[0035] A further solution of the present invention generates a magnetic field enhancement signal, comprising the following steps:

[0036] Guide the heat dissipation airflow through the annular magnetic grid to cut the magnetic lines of force and generate an axially stable magnetic field;

[0037] Read the real-time speed of the cooling fan and adjust the magnetic saturation intensity;

[0038] The anti-vibration stabilization signal is input to the induction coil surrounding the annular magnetic grid, so that the signal carrier is electromagnetically coupled with the axial stabilization magnetic field to generate a magnetic field enhancement signal.

[0039] A further embodiment of the present invention generates an environmentally optimized energy flow, comprising the following steps:

[0040] When the humidity value of the dynamic interference parameter set exceeds the preset humidity threshold, the high-voltage electrostatic generator is triggered to release high-voltage static electricity to the surface of the waveguide groove, ionizing the water molecules adsorbed on the surface of the wavy continuous groove pattern of the waveguide groove to form a uniform water-repellent film;

[0041] The dehumidification heat is converted into electric current through the semiconductor thermocouple and introduced into the magnetic grid;

[0042] The current in the annular magnetic grid generates Joule heat to increase the temperature of the annular magnetic grid. The heat diffuses into the airflow through the grid of the annular magnetic grid to form a thermal circulation field. The thermal circulation field enhances signal stability and generates an environmentally optimized energy flow.

[0043] A further solution of the present invention is to output a collaborative enhancement signal, comprising the following steps:

[0044] The environmentally optimized energy flow acts on the magnetic coating of the magnetic grid to increase magnetic permeability;

[0045] Obtain real-time angle data of the receiving head rotation mechanism;

[0046] Dynamically calculate the signal gain coefficient based on the spatial angle and temperature change;

[0047] The gain coefficient is multiplied by the carrier amplitude of the magnetic field enhancement signal to generate a radio frequency waveform with optimized carrier energy to output a collaborative enhancement signal.

[0048] A further solution of the present invention generates a visual operation guide, comprising the following steps:

[0049] The synergistic enhancement signal intensity was converted into normalized intensity percentage;

[0050] The normalized intensity is compared with a preset intensity color mapping table, and a corresponding pulse width modulation signal is generated according to the comparison result;

[0051] The intensity color mapping table sets the low color mapping threshold and the high color mapping threshold. When the normalized intensity percentage is less than the low color mapping threshold, it is displayed in red; when the normalized intensity percentage is between the low color mapping threshold and the high color mapping threshold, it is displayed in yellow; when the normalized intensity percentage is greater than the high color mapping threshold, it is displayed in green.

[0052] Generate a pulse width modulation signal to drive the RGB LED light ring to display a visual operation guide corresponding to the color gradient.

[0053] In summary, the present invention has the following beneficial technical effects:

[0054] 1. The mechanical vibration compensation unit and the receiver head deflection control form a closed-loop linkage. Within the millisecond time window generated by vibration interference, a counteracting mechanical force and signal angle correction are generated simultaneously, effectively canceling out high-frequency phase shifts in real time. The cooling airflow is converted into an axially stable magnetic field carrier, transforming the interference source of the traditional cooling system into a signal-enhancing medium through thermal-magnetic coupling. The waveguide groove's water-repellent film and heat recovery mechanism form an environmentally adaptive loop, blocking water vapor adsorption while utilizing waste heat to enhance magnetic permeability. The triple physical fields, under unified control timing, form a positive gain loop, breaking through the bottleneck of mutually constrained performance among various modules in traditional solutions.

[0055] 2. After standardized integration of vibration, temperature, humidity, and fan speed data, the system drives the coordinated calculation of vibration compensation current and receiver head deflection angle, eliminating control delays caused by discrete sensors. A mechanism dynamically adjusts magnetic saturation intensity with fan speed, converting heat dissipation energy into controllable electromagnetic resources. A humidity threshold triggers a cascade reaction between a water-repellent film and thermoelectric power generation, establishing a chain of transformation between environmental interference and energy reuse. This global optimization strategy ensures that the system maintains consistent and stable signal compensation even in situations with sudden strong vibrations and rapid temperature changes.

[0056] 3. LED color gradient display based on signal strength mapping breaks through the cognitive barrier of traditional instrument numerical display. The deflection status of the receiving head is synchronized with the frequency of light flashing to warn, preventing human misjudgment of device orientation. The activation status of the environmental optimization energy flow is dynamically indicated by breathing lights, providing visual monitoring of energy-saving operation. This design upgrades the device from an isolated communication node to an intelligent terminal with self-diagnosis and guidance capabilities, significantly lowering the professional threshold for deployment and commissioning.

[0062] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Figures 1-2 The present application proposes a signal reception quality enhancement auxiliary system based on a millimeter wave communication device, comprising the following modules:

[0063] A rotating scanning module is used for continuously rotating and scanning the receiving head by driving and capturing the millimeter wave signals reflected by the environment to generate a multi-directional composite signal stream.

[0064] An interference detection module is used for collecting the vibration intensity of the device, the temperature and humidity of the environment and the rotating speed of the heat dissipation fan in real time to generate a dynamic interference parameter set.

[0065] A vibration compensation module is used for generating a vibration cancellation current based on the vibration data in the dynamic interference parameter set to control the deflection of the receiving head to output an anti-vibration stable signal.

[0066] A magnetic field reconstruction module is used for generating an axial stable magnetic field by cutting the magnetic grid with the heat dissipation airflow, superimposing the anti-vibration stable signal and the axial stable magnetic field to generate a magnetic field enhancement signal.

[0067] An environmental linkage module is used for forming a water-repellent film and guiding the dehumidification heat into the magnetic grid to generate an environmental optimization energy flow when the humidity value of the dynamic interference parameter set exceeds a preset threshold.

[0068] A signal fusion module is used for coupling the magnetic field enhancement signal and the environmental optimization energy flow, adjusting the gain coefficient through the rotating angle of the receiving head and outputting a synergistic enhancement signal.

[0069] A pointing feedback module is used for controlling the color gradient of the LED aperture display according to the intensity change of the synergistic enhancement signal to generate a visual operation guide.

[0070] In one of the embodiments of the present application, the generation of the multi-directional composite signal stream comprises the following steps:

[0071] The receiving head is continuously rotated and scanned by a micro motor for 360 degrees, the millimeter wave signals reflected by the environment are captured by the waveguide groove on the surface of the metal shell of the device to generate a multi-directional composite signal stream.

[0072] Specifically, the millimeter-wave communication device contains a built-in micromotor, whose output shaft is connected to the rotating base of the millimeter-wave receiving head. When the millimeter-wave communication device is powered on, the micromotor drives the receiving head at a constant speed of 5-10 revolutions per second for continuous 360-degree rotation and scanning. The micromotor uses a constant-torque miniature stepper motor, and its speed is determined by experimental data on the millimeter-wave signal decay period, ensuring that the receiving head can complete omnidirectional scanning within 20ms. Simultaneously, a waveguide groove pre-machined on the surface of the device's metal casing begins to capture millimeter-wave signals reflected from the environment. The waveguide groove refers to a continuous, wavy groove pattern with a depth of 0.1-0.3mm, formed on the surface of the device's metal casing by laser etching. The wave period of the waveguide groove is set to N times the millimeter-wave wavelength, with N ranging from 1 / 4 to 1 / 2. The depth and wave period of the waveguide groove were determined through comparative experiments on reflected wave enhancement using 16 different groove depth-period combinations. The electromagnetic field modulation effect of the waveguide groove on the device's metal casing is used to force the reflected waves from the environment to dynamically converge toward the rotating receiving head.

[0073] When a millimeter-wave signal strikes a person or an obstruction such as a wall, the reflected millimeter wave propagates along the surface of the device's metal casing. The waveguide slot alters the current distribution on the metal casing, forcing the reflected wave toward the receiving head. The rotating receiving head continuously receives direct waves from the front and reflected waves converged by the waveguide slot. An adaptive delay compensation circuit aligns the multipath signal phases. The direct wave and at least three reflected waves from different directions are superimposed in the time domain to form a mixed waveform. This creates a spatial phase matching relationship that depends on the receiving head's rotational position and the waveguide slot's wavy, continuous groove pattern. The output is a multi-directional composite signal stream.

[0074] For example, referring to Appendix 1, 16 groups (only 3 groups are listed in the appendix) of reflection wave enhancement comparison experiments with different groove depth-period combinations are conducted. The comparison experiments are based on millimeter wave communication characteristics simulation and actual measurement verification, proving that the depth of 0.2mm + period λ / 3 is the optimal combination.

[0075] Guided wave groove parameter combinations Reflection signal gain (dB) Multipath identification rate Depth 0.1 mm + period λ / 4 +8.2 92.1％ Depth 0.2 mm + period λ / 3 +12.7 96.4％ Depth 0.3 mm + period λ / 2 +9.5 87.3％

[0076] Appendix 1 Example of reflection wave enhancement comparison experiment

[0077] In one embodiment of the present invention, generating a dynamic interference parameter set includes the following steps:

[0078] The device vibration intensity collected by the piezoelectric ceramic sensor, the ambient temperature and humidity collected by the temperature and humidity integrated sensor, and the cooling fan speed collected by the Hall effect ammeter are aligned according to the timestamp to generate a dynamic interference parameter set.

[0079] Specifically, piezoelectric ceramic sensors are attached to the four corners of the metal shell of the device. The piezoelectric ceramic sensors are crystal sheets made of lead zirconate titanate crystal material. The attachment position of the piezoelectric ceramic sensors must avoid the wavy continuous groove pattern area of ​​the waveguide slot to ensure that vibration detection is not affected by the waveguide slot structure. When the device vibrates due to external force, the piezoelectric ceramic sensor generates microcurrent due to its own deformation. The vibration intensity of the device is the mechanical vibration acceleration value converted from the current signal, which satisfies the formula: a = C (I-I0), where a represents the vibration acceleration, and the unit is m / s. 2 I represents the microcurrent measured by the piezoelectric ceramic sensor, in mA; I0 is the no-load reference current, which is determined according to the equipment specifications and has a value range of 0.15%-3% of the rated current, in mA; C represents the current-acceleration conversion coefficient, which is determined by the vibration table calibration experiment and has a value range of 0.05-0.2, in m / s 2 ) / mA.

[0080] An integrated temperature and humidity sensor is installed at the ventilation hole position of the metal casing of the equipment. The probe of the integrated temperature and humidity sensor is directly exposed to the air to detect the ambient temperature and relative humidity in real time. The probe surface of the integrated temperature and humidity sensor is coated with a nano-hydrophobic coating to prevent condensation of water droplets in a high humidity environment from affecting the detection accuracy. The unit of the ambient temperature T is ℃, and the unit of the relative humidity H is %.

[0081] The power supply line of the cooling fan motor is connected in series with a Hall ammeter. By measuring the driving current and converting it into the real-time fan speed, the following formula is satisfied: N = K × I fan , N is the real-time fan speed, in revolutions per minute (RPM); I fan is the current value measured by the Hall effect ammeter, which is the real-time working current driving the cooling fan motor, in milliamperes (mA); K is the motor characteristic coefficient, calibrated through no-load-rated load experiments, with a value range of 0.1-10, and the unit is RPM / mA.

[0082] The equipment vibration intensity output by the piezoelectric ceramic sensor, the ambient temperature and relative humidity collected by the temperature and humidity integrated sensor, and the cooling fan speed are aligned according to the timestamp. The numerical dimensions of all parameters are uniformly converted into dimensionless standardized parameters to generate a dynamic interference parameter set containing four-dimensional data. The following formula is satisfied: X std =(X raw -μ) / σ,X std represents the dimensionless parameter after standardization; X raw represents the original parameter value; μ represents the historical mean of the parameter, and σ represents the historical standard deviation of the parameter. The latest 100 sets of historical statistics are calculated using rolling calculations. The dynamic interference parameter set is stored in an array as a mapping table of time, device vibration intensity, temperature, humidity, and fan speed.

[0083] In one embodiment of the present invention, outputting an anti-vibration stabilization signal includes the following steps:

[0084] According to the vibration intensity of the device in the dynamic interference parameter set, a vibration-cancelling current with reverse vibration is generated and acts on the device mainboard. The signal of the vibration-cancelling current is transmitted to the receiving head rotation mechanism, triggering the receiving head to deflect in the opposite direction of the vibration and output an anti-vibration stabilization signal.

[0085] Specifically, after generating the dynamic interference parameter set, the device vibration intensity data is extracted through the dynamic interference parameter set. The device vibration intensity data is the acceleration value converted by the piezoelectric ceramic sensor and is input into the vibration compensation controller. The vibration compensation controller generates the vibration cancellation current for the reverse vibration based on the preset acceleration current mapping table. The acceleration current mapping table stores the corresponding relationship between vibration acceleration and cancellation current, which satisfies the following formula: I m =(M·a) / B,I m represents the offset current in amperes (A); M represents the mass of the device in kilograms (kg); a represents the target acceleration in m / s 2 ; B represents the force constant of the electromagnetic brake. According to the data provided by the manufacturer, the value range of B is 5-10N / A, and the unit is N / A.

[0086] The vibration-cancelling current is transmitted to the electromagnetic brake on the mainboard of the device to generate a reverse mechanical force, and the vibration-cancelling current signal is simultaneously transmitted to the micro-motor of the receiving head rotation mechanism. The micro-motor calculates the deflection angle of the receiving head according to the current intensity ratio: θ = A × k m ; θ represents the deflection angle of the receiving head, in degrees; A represents the vibration acceleration value, in m / s 2 ;k m is the vibration angle conversion coefficient, unit is °·s 2 / m; vibration angle conversion coefficient k m Determined by vibration table test, the typical value is k m Equal to 0.5°·s 2 / m, combined with the deflection angle of the receiving head, the micro motor drives the receiving head to deflect in the opposite direction of vibration.

[0087] After deflection, the receiving head continues to receive the multi-directional composite signal flow gathered by the waveguide slot, compensates for the signal phase shift caused by vibration, and outputs an anti-vibration stable signal. The anti-vibration stable signal is the waveform of the multi-directional composite signal flow after deflection compensation by the receiving head.

[0088] In one embodiment of the present invention, generating a magnetic field enhancement signal includes the following steps:

[0089] To reconstruct the heat dissipation electromagnetic field, air flow is introduced into the annular magnetic grid (a metal mesh cover with a magnetic coating) outside the cooling fan. The air flow cuts the annular magnetic grid to generate an axially stable magnetic field. The anti-vibration stability signal is superimposed on the axially stable magnetic field to generate a magnetic field enhancement signal.

[0090] Specifically, the airflow generated by the device's cooling fan is directed into a ring-shaped magnetic grid (a metal mesh with a magnetic coating). This grid houses a neodymium iron boron permanent magnet base and has a mesh density of 20-30 holes per square centimeter. Wind tunnel testing has determined this density balances airflow and magnetic field generation efficiency. The grid's surface is evenly sprayed with a ferrite coating with a thickness of 0.2mm-0.5mm. Its magnetic permeability parameter, μ, is set to 1200 Henry per meter. Electromagnetic simulations have verified that it can generate a stable axial magnetic field of 5-8 millitesla under conventional cooling airflow. The grid is coaxially mounted with the receiving head's rotating axis, with an eccentricity error of ≤0.1mm.

[0091] When the airflow flows through the grid gap of the annular magnetic grid at a speed of 3m-5m per second, the airflow cuts the magnetic lines of force on the surface of the annular magnetic grid to generate an axial stable magnetic field perpendicular to the mainboard of the device. At the same time, the real-time cooling fan speed data is read according to the cooling fan drive circuit, and the magnetic saturation intensity of the annular magnetic grid is adjusted according to the cooling fan speed to meet the following formula: B max =C·N;B max The magnetic saturation intensity of the annular magnetic grid is expressed in millitesla (mT). N represents the speed of the cooling fan in revolutions per minute (r / min). C is the magnetic field conversion constant, typically 0.02, expressed in millitesla minutes per revolution (mT·min / r). The setting of C = 0.02mT·min / r is based on the Hall effect ammeter's measurement of a 6mT magnetic field at a fan speed of 3000 rpm.

[0092] The anti-vibration stabilization signal is input into the induction coil surrounding the annular magnetic grid, causing electromagnetic coupling between the signal carrier and the axial stabilization magnetic field. This electromagnetic coupling process automatically compensates for signal phase shifts based on the magnetic field strength. The electromagnetic coupling process complies with Faraday's law of electromagnetic induction. The alternating magnetic field induces eddy currents in the ferrite coating of the annular magnetic grid, which in turn generate an additional magnetic field of the same frequency. The axial coaxiality of the induction coil and the annular magnetic grid (error ≤ 0.1mm) and the number of coil turns are precisely controlled to ensure that the additional magnetic field and the axial stabilization magnetic field remain in phase. The axial stabilization magnetic field strength is monitored in real time. If the magnetic field strength drifts due to temperature changes, the phase angle of the induction coil current is dynamically adjusted through a negative feedback circuit. Ultimately, the carrier of the anti-vibration stabilization signal and the additional magnetic field are superimposed in space vectors, resulting in a fused magnetic field with enhanced amplitude and consistent phase, which is output as a magnetic field enhancement signal.

[0093] In one embodiment of the present invention, generating an environment-optimized energy flow includes the following steps:

[0094] When the humidity value of the dynamic interference parameter set exceeds the preset humidity threshold, static electricity is released to the surface of the waveguide groove to form a water-repellent film. At the same time, the heat generated by the dehumidification process is introduced into the annular magnetic grid to generate an environmental optimization energy flow.

[0095] Specifically, after the magnetic field enhancement signal is generated, the dynamic interference parameter set is continuously monitored. When the humidity value of the dynamic interference parameter set exceeds the preset humidity threshold, the humidity threshold is set based on the millimeter wave scattering experiment in humid air, with a typical value of 80%. When the magnetic field enhancement signal intensity is lower than -90dBm, the humidity threshold is automatically lowered to 75% to prevent signal interruption, triggering the high-voltage electrostatic generator to release DC static electricity with a positive voltage of 12 kilovolts to the surface of the waveguide groove. The ionization of DC static electricity with a positive voltage of 12 kilovolts is the core mechanism of dehumidification. The water molecules adsorbed on the surface of the wavy continuous groove pattern of the waveguide groove are ionized to form a uniform water-repellent film with a thickness of 0.01mm-0.03mm.

[0096] The semiconductor thermocouple installed on the base of the waveguide slot is started synchronously to convert the heat generated by the dehumidification process into low-voltage current: Q e =η·Q c ;Q e Represents the output electrical energy in joules; Q c represents the heat generated during the dehumidification process, in joules; η represents the conversion efficiency of the semiconductor thermocouple, which is set in combination with the semiconductor material. For example, when using a TGM1-127 semiconductor thermocouple, the measured conversion efficiency is 4.8% when ΔT = 10°C.

[0097] Low-voltage current is introduced into the ferrite magnetic coating of the annular magnetic grid. The current in the ferrite magnetic coating generates Joule heat to increase the temperature of the annular magnetic grid. The heat diffuses into the airflow through the grid of the annular magnetic grid to form a thermal circulation field. The thermal circulation field enhances signal stability and generates an environmental optimization energy flow. The environmental optimization energy flow is a stable thermal magnetic coupling field formed when the surface temperature of the annular magnetic grid rises by 3°C-5°C.

[0098] In one embodiment of the present invention, outputting a collaborative enhancement signal includes the following steps:

[0099] The magnetic field enhancement signal is coupled with the environmental optimization energy flow, and the signal gain coefficient is adjusted in real time by the rotation angle of the receiving head to output a synergistically enhanced signal.

[0100] Specifically, a magnetic field enhancement signal is input into the induction coil surrounding the annular magnetic grid. The environmentally optimized energy flow acts on the ferrite coating of the annular magnetic grid via thermal conduction. The temperature increase of the ferrite coating increases its magnetic permeability, which in turn increases the carrier amplitude of the magnetic field enhancement signal in the induction coil. This increase in magnetic permeability is determined based on the material properties of the ferrite coating, such as PC40 MnZn ferrite (temperature coefficient +0.2% / °C).

[0101] The real-time angle data of the receiving head rotation mechanism is obtained. The real-time angle data is output by the encoder in the micro motor in units of degrees. Based on the spatial relative position of the receiving head rotation angle and the axial magnetic field of the annular magnetic grid, the signal gain coefficient is dynamically calculated to meet the following formula: k gain is the signal gain coefficient; k0 is the baseline gain coefficient, which is measured based on the original signal loss data of the waveguide slot, with a typical value of 1.2; α represents the temperature gain factor. Through testing, it is determined that the magnetic permeability of the ferrite magnetic coating increases by 0.4% for every 1°C increase in temperature, which corresponds to a 0.5% increase in signal amplitude, or a typical value of 0.005 / °C; ΔT represents the temperature change caused by the environmental optimization energy flow, in degrees Celsius; It is the angle between the normal line of the receiving head and the axial magnetic field of the annular magnetic grid, and the unit is degree.

[0102] The gain coefficient is multiplied by the carrier amplitude of the magnetic field enhancement signal to generate an RF waveform with optimized carrier energy. Finally, the waveform is integrated through an envelope detection circuit (such as the ADL5511 chip, which supports 28GHz millimeter wave demodulation) to output a collaborative enhancement signal. The collaborative enhancement signal is a baseband signal formed after carrier energy optimization and envelope detection.

[0103] In one embodiment of the present invention, generating a visual operation guide includes the following steps:

[0104] Based on the intensity changes of the collaborative enhancement signal, the LED aperture around the control device displays a color gradient to generate visual operation instructions.

[0105] Specifically, after the collaborative enhancement signal is output, the execution is continued, and the baseband waveform of the collaborative enhancement signal is extracted to obtain the real-time signal strength value. The real-time signal strength value is converted into a normalized strength in percentage format by a digital signal processor in dBm, satisfying the following formula: S n =100×(S m -S min ) / (S max -S min );S n represents the normalized intensity percentage, S m The real-time signal strength extracted from the baseband waveform representing the collaboratively enhanced signal; Smin representative minimum signal strength detectable by the device, typical value is -120dBm, S max representative maximum signal strength of the device, typical value is -30dBm, based on the sensitivity limit of the millimeter wave receiving module.

[0107] According to the comparison result, a corresponding pulse width modulation signal is generated, which satisfies the following formula: D c =K c ·S n ; D c represents the duty cycle of the pulse width modulation signal, S n represents the normalized intensity percentage; K c is a color saturation coefficient, which is determined by joint experiments of human eye visual characteristics and LED optical performance, and is verified by the recognition efficiency test of 20 subjects in outdoor scenes. The pulse width modulation signal is transmitted to the RGB LED aperture driving circuit embedded in the edge of the device metal shell, the embedded RGB LED aperture driving circuit controls the LED chip to emit light, and the light color duration is 200ms to 500ms, and the breathing flicker effect is added to ensure that the human eye can clearly identify. Finally, a visible light prompt ring with a diameter of 5cm to 8cm is formed on the periphery of the device, and a visual operation guide is generated.
