TECHNICAL FIELD
[0001] The present application relates to the technical field of vehicle lock unlocking control, and particularly relates to a voiceprint unlocking intelligent vehicle lock system and method. BACKGROUND
[0002] As an important tool for short-distance travel, the electric bicycle is an important part of the electric bicycle, and the lock is a key part of the electric bicycle. The lock is used frequently to ensure the safety of the electric bicycle. However, the traditional mechanical lock and the electronic lock have the problems of high rate of theft, easy loss of key and remote control safety hazard. The voiceprint recognition technology is particularly suitable for electric bicycles which need to be frequently unlocked and are cost-sensitive. However, the current voiceprint recognition technology needs to be further improved in terms of intelligence, and the voice recognition is fixed and cannot effectively perform related operations according to the user's requirements. The identity recognition accuracy of the electric bicycle is low under complex working conditions such as vibration and wind noise. SUMMARY
[0003] To achieve the above purpose, the technical scheme adopted by the present application is as follows:
[0004] In one aspect of the present application, a voiceprint unlocking intelligent vehicle lock system is provided, comprising:
[0005] A modal resonance excitation subsystem is used to generate a frame structure eigen-vibration spectrum based on an output elastic structure fingerprint. The frame structure eigen-vibration spectrum is modulated by the frame structure material resonance mode and the rider contact stiffness. The structure carrier wave resonance is excited only when the sound frequency matches the specific mode. The rider needs to excite resonance at the sound frequency of the structure carrier wave resonance, so that the energy node distribution is generated at the handlebar or the seat cushion.
[0006] A motion entropy field verification body subsystem is used to input the generated energy node distribution into a motion entropy processor, and generate a riding voiceprint entropy field in combination with the riding state. By mapping the parameters of the riding voiceprint entropy field to the deformation tolerance of the preset human-vehicle coupling constraint domain, the unlocking is triggered when the tolerance interval converges to the threshold value.
[0007] In another aspect of the present application, a voiceprint unlocking intelligent vehicle lock method of a voiceprint unlocking intelligent vehicle lock system is provided, comprising the following steps:
[0008] When the rider of the electric bicycle makes a sound, the sound wave of the sound is collected in the tubular transmission wave of the frame structure of the electric bicycle. By analyzing the multi-phase damping oscillation formed by the sound wave at the contact point of the tubular wall of the frame structure and the rider, a dynamic boundary waveguide mechanism is constructed. The dynamic boundary waveguide mechanism converts the frame structure into an acoustic transmission line with an elastic structure fingerprint. The waveguide characteristics of the acoustic transmission line integrate the geometric characteristics of the frame structure and the biomechanical characteristics of the rider.
[0009] Generate the frame structure eigen vibration spectrum based on the output-based elastic structure fingerprint; the frame structure eigen vibration spectrum is modulated by the frame structure material resonance mode and the rider contact stiffness, and the structure carrier wave resonance is excited only when the sound emission frequency matches a specific mode; the rider needs to excite resonance at the sound emission frequency of the structure carrier wave resonance to generate an energy node distribution at the handlebar or seat cushion;
[0010] Input the generated energy node distribution into a motion entropy processor to generate a riding voiceprint entropy field in combination with the riding state; by mapping the parameters of the riding voiceprint entropy field to the deformation tolerance of the preset human-vehicle coupling constraint domain, the unlocking is triggered when the tolerance interval converges to a threshold value.
[0011] The present application realizes biomechanical identity authentication based on human-vehicle coupling characteristics through multi-module cooperation, and its technical significance mainly lies in that the elastic boundary waveguide modeling subsystem combines the mechanical impedance characteristics of the frame structure with the biomechanical characteristics of the rider when sounding, such as contact stiffness and damping characteristics, to form a unique elastic structure fingerprint, which not only contains geometric parameters such as pipe diameter, wall thickness and included angle of the frame material, but also integrates acoustic modulation characteristics such as soft tissue damping and skeletal conduction of the rider's body organization, realizing deep coupling of physical structure and physiological characteristics. The modal resonance excitation subsystem requires the rider to accurately excite a specific resonance mode of the frame structure through the matching mechanism of the eigen vibration spectrum, which has a double anti-counterfeiting feature: on the one hand, it needs to match the natural frequency of the frame material, and on the other hand, it needs to meet the stiffness condition of the human-vehicle contact interface, such as palm pressure and sitting contact area; only when the structure resonance and biomechanical constraints are met at the same time, can a detectable energy node be formed at the specified position of the handlebar / seat cushion. The motion entropy field verification subsystem constructs a human-vehicle coupling characteristic field containing time and space dimensions by monitoring the dynamic characteristics of the spatial trajectory, intensity distortion rate and phase difference of the energy node. The innovation of the system lies in extending the static voiceprint to a dynamic entropy field, and realizing continuous identity verification in the motion state by quantifying the signal stability under wind shear interference and the nonlinear distortion caused by acceleration.

[0024] Embodiment 1:
[0025] As shown in Figure 1 , the embodiments of the present application provide a voiceprint unlocking intelligent bicycle lock system (the principle is referred to the attached Figure 2 , which comprises:
[0026] The elastic boundary waveguide modeling subsystem is used to collect the tubular transmission wave of the sound wave when the rider of the electric bicycle makes a sound in the frame structure of the electric bicycle; a dynamic boundary waveguide mechanism is constructed by analyzing the multi-phase damping oscillation of the sound wave at the contact point of the tubular wall of the frame structure and the rider; the dynamic boundary waveguide mechanism converts the frame structure into an acoustic transmission line with an elastic structure fingerprint, and the waveguide characteristics of the acoustic transmission line integrate the geometric characteristics of the frame structure and the biomechanical characteristics of the rider;
[0027] The modal resonance excitation subsystem is used to generate a frame structure intrinsic vibration spectrum based on the output elastic structure fingerprint; the frame structure intrinsic vibration spectrum is modulated by the frame structure material resonance mode and the rider contact stiffness, and only when the sound frequency matches a specific mode, the structure carrier wave resonance is excited; the rider needs to excite resonance at the sound frequency of the structure carrier wave resonance, so that the energy node distribution is generated at the handlebar or the seat cushion;
[0028] The motion entropy field verification body subsystem is used to input the generated energy node distribution into a motion entropy processor, and generate a riding voiceprint entropy field in combination with the riding state; by mapping the parameters of the riding voiceprint entropy field to the deformation tolerance of the preset human-vehicle coupling constraint domain, when the tolerance interval converges to a threshold value, the unlocking is triggered;
[0029] The riding voiceprint entropy field comprises: the migration trajectory of the energy node in the frame space, the distortion rate of the node intensity with acceleration, and the phase difference between the wind shear sound and the structure resonance.
[0030] In the above-mentioned embodiment, the voiceprint unlocking smart car lock system of this embodiment achieves biomechanical identity authentication based on the coupling characteristics of human and vehicle through the collaboration of multiple modules. Its technical significance lies in the following: the elastic boundary waveguide modeling subsystem combines the mechanical impedance characteristics of the frame structure with the biomechanical characteristics of the rider's voice, such as contact stiffness and damping characteristics, to form a unique elastic structural fingerprint. This fingerprint not only includes geometric parameters of the frame material, such as tube diameter, wall thickness, and angle, but also integrates the acoustic modulation characteristics of the rider's human tissue, such as soft tissue damping and bone conduction, achieving deep coupling between physical structure and physiological characteristics. The modal resonance excitation subsystem, through the matching mechanism of the intrinsic vibration spectrum, requires the rider to accurately excite specific resonant modes of the frame structure, thus providing dual anti-counterfeiting features: on the one hand, it must match the natural frequency of the frame material, and on the other hand, it must meet the stiffness conditions of the human-vehicle contact interface, such as palm pressure and sitting contact area. Only when both structural resonance and biomechanical constraints are met can a detectable energy node be formed at the specified position of the handlebar / seat. The motion entropy field verification subsystem constructs a characteristic field for human-vehicle coupling that encompasses both spatial and temporal dimensions by monitoring the spatial trajectory, intensity distortion rate, and phase difference of energy nodes. The system's innovation lies in expanding the static voiceprint into a dynamic entropy field. By quantifying signal stability under wind shear interference and nonlinear distortion caused by acceleration, it enables continuous authentication in motion.
[0031] In summary, this embodiment establishes a three-tiered authentication system: structural conduction, modal excitation, and motion verification. This upgrades traditional voiceprint recognition to a multi-dimensional authentication system that incorporates frame mechanical characteristics, riding dynamics, and environmental factors. Without the need for additional sensors, the frame itself serves as a waveguide, enabling embedded biometric collection while maintaining mechanical strength. This solves the problem of reliable identification of e-bikes in complex operating conditions such as vibration and wind noise.
[0032] Example 2:
[0033] like Figure 3 As shown, based on Example 1, the elastic boundary waveguide modeling subsystem provided by the embodiment of the present invention includes:
[0034] The multi-phase damped oscillation feature extraction module is used to extract the biomechanical damping fingerprint of each contact point by capturing the asymmetric propagation delay of the ripples in the three-sided tubular structure of the frame.
[0035] The biomechanical damping fingerprint includes: the acoustic energy attenuation slope of the seat cushion contact area, the ripple reflection phase shift of the handlebar point, and the frequency dispersion distortion rate of the pedal contact surface;
[0036] The topological constraint waveguide synthesis module is used for inputting the biomechanical damping fingerprint into a frame geometry constraint field according to the spatial topological relationship of the frame structure; the dynamic boundary conduction mechanism is generated by fusing the biomechanical damping fingerprint, the upper tube and the vertical tube included angle to determine the longitudinal waveguide curvature and the lower tube and the rear fork length ratio to generate the transverse harmonic suppression coefficient; and the waveguide path constraint of the sound wave under the elastic boundary condition is quantified.
[0037] The living body coupling transmission line generation module is used for field coupling of the dynamic boundary conduction mechanism and the real-time parameters of the seat cushion pressure distribution and the hand holding stiffness of riding; the attenuation flux of the conduction matrix is modulated by the seat cushion pressure gradient, and the stress refractive index of the waveguide path is remodeled to dynamically calibrate the conduction matrix according to the hand holding stiffness, and finally the elastic structure fingerprint acoustic transmission line with living body adaptability is output.
[0038] In the above embodiment, the elastic boundary waveguide modeling subsystem of the embodiment realizes accurate modeling and dynamic optimization of the sound wave conduction characteristics of the bicycle frame structure through the cooperative work of multiple modules. Specifically, the multiple-phase damping oscillation characteristic extraction module quantifies the biomechanical damping characteristics of the seat cushion, handlebar and pedal contact points by capturing the asymmetric sound wave conduction delay in the three-edge tubular structure of the frame, and provides input parameters for the system, including the attenuation slope, phase shift and frequency dispersion distortion rate. The topological constraint waveguide synthesis module generates a dynamic boundary conduction mechanism based on the frame geometry constraint field, such as the upper tube-vertical tube included angle, the lower tube-rear fork length ratio and the biomechanical damping fingerprint. The path constraint of the sound wave conduction under the elastic boundary condition is quantified, including the longitudinal waveguide curvature and the transverse harmonic suppression coefficient. The coupling transmission line generation module dynamically calibrates the attenuation flux and stress refractive index of the conduction matrix by fusing the real-time parameters of riding, such as the seat cushion pressure gradient and the hand holding stiffness, and finally outputs the elastic structure fingerprint acoustic transmission line adapted to the current riding state.
[0039] In summary, the embodiment accurately characterizes the sound wave conduction characteristics of the frame structure under dynamic load by coupling acoustic waveguide modeling and biomechanical parameters, and provides a quantitative basis for frame vibration suppression, material optimization or riding posture adjustment. The modules form a closed loop: characteristic extraction, topological constraint modeling, real-time parameter coupling and transmission line generation, realizing full-link acoustic conduction simulation from static geometry to dynamic load.
[0040] Embodiment 3:
[0041] On the basis of embodiment 1, the modal resonance excitation subsystem provided by the embodiment of the application comprises:
[0042] A biomechanical spectrum modulation component is used to input the elastic structure fingerprint into the contact stiffness field, and extract the living resonance modulation factor through real-time feedback of the cyclist's palm pressure gradient and the saddle deformation depth. It contains the dynamic stiffness coefficient of the handlebar grip point area, the damping attenuation rate of the saddle contact interface, and the energy reflection phase of the pedal force point.
[0043] An intrinsic vibration field synthesis component is used to couple the living resonance modulation factor with the inherent properties of the frame material. By coupling the living resonance modulation factor, the Young's modulus of the frame tube material, and the stress distribution of the welding point, a three-dimensional field convolution of the harmonic suppression domain is derived, and the frame structure intrinsic vibration spectrum with human-vehicle coupling characteristics is synthesized. The resonance peak position is dynamically shifted by the biomechanical parameters.
[0044] A carrier resonance excitation component is used to excite stress standing waves inside the frame when the rider's voice frequency matches the main modal of the frame structure intrinsic vibration spectrum. The standing wave forms a high stress antinode density at the handlebar stand pipe and a low energy node at the saddle support point. Through the spatial coupling of the high stress antinode density and the low energy node, an energy node distribution is formed, and its topological structure is determined by the frame geometry and the living modulation factor.
[0045] A dynamic resonance verification component is used to monitor the stability of the stress standing wave in real time. The gradient of the antinode density and the spatial consistency of the high stress antinode density generate the resonance confidence coefficient. The time-domain correlation of the anti-node energy attenuation rate and the low-energy anti-node generates the energy convergence factor. When the product of the resonance confidence coefficient and the energy convergence factor exceeds the critical threshold, it is determined that the energy node distribution is effective.
[0046] In the above embodiment, the modal resonance excitation subsystem of the embodiment realizes accurate regulation and verification of the resonance characteristics of the bicycle frame structure during riding through the synergistic effect of multiple components. The specific function decomposition is as follows: the biomechanical spectrum modulation component extracts the resonance modulation factor, dynamic stiffness coefficient, damping attenuation rate, and energy reflection phase through the palm pressure gradient of the rider, seat deformation depth, and pedal force point feedback, and provides dynamic parameter input of human-vehicle interaction for the system. The intrinsic vibration field synthesis component couples the resonance modulation factor with the inherent properties of the frame material, Young's modulus, and stress distribution at the welding point to generate a three-dimensional field convolution of the base frequency dispersion and the harmonic suppression domain, and outputs the frame intrinsic vibration spectrum modulated by the dynamic biomechanical parameters, and the resonance peak position changes with the riding state. The carrier wave resonance excitation component excites the stress standing wave inside the frame when the rider's sound frequency matches the main modal of the frame intrinsic vibration spectrum, forms a spatial distribution of high stress antinode density at the handlebar riser and low energy node at the seat support point, and its topological structure is determined by the frame geometry and the resonance modulation factor. The dynamic resonance verification component calculates the resonance confidence coefficient and the energy convergence factor by monitoring the antinode density gradient and the time domain energy attenuation rate of the stress standing wave; when the product of the two exceeds the threshold, it is determined that the current energy node distribution meets the resonance stability requirements.
[0047] In summary, the embodiment dynamically combines the intrinsic vibration spectrum of the human-vehicle coupling through the coupling of biomechanical parameters and frame material properties, and excites a controllable stress standing wave under acoustic excitation. Finally, through the real-time verification mechanism, the stability of the resonance energy distribution is ensured, providing a quantitative basis for active control of frame vibration, optimization of resonance frequency, or evaluation of structural safety. The components form a closed loop link: parameter modulation, vibration spectrum synthesis, standing wave excitation, and dynamic verification, realizing the whole process regulation from biomechanical input to resonance characteristic output.
[0048] Embodiment 4:
[0049] Based on embodiment 3, the dynamic resonance verification component provided by the embodiment of the application comprises:
[0050] The spatial consistency quantization sub-component is used to monitor the stress standing wave energy field on the surface of the frame in real time, extract the instantaneous antinode density distribution in the handlebar riser area, perform spatial convolution on the instantaneous antinode density distribution and the high stress antinode density template pre-generated by the carrier wave resonance excitation component, obtain the geometric center offset vector of the antinode cluster, measure the topological distortion rate of the antinode spacing, and generate the antinode spatial fidelity through vector synthesis of the geometric center offset vector and the topological distortion rate. The scalar value reflects the spatial consistency degree of the actual distribution and the theoretical template.
[0051] The time domain attenuation correlation subcomponent is used for synchronously collecting the anti-node energy time sequence of the seat support point, performing third-order differentiation on the attenuation curve to extract the energy curvature feature, performing time domain correlation on the energy curvature feature and a pre-stored low-energy anti-node reference model, comparing the time domain positioning deviation of the energy valley, and obtaining the curvature similarity of the attenuation slope; and the anti-node time domain convergence factor is derived through the weighted fusion of the time domain positioning deviation and the curvature similarity.
[0052] The dynamic confidence fusion subcomponent is used for inputting the antinode space fidelity into the frame deformation constraint field, adjusting the confidence weight in real time according to the riding posture, generating a space verification tolerance coefficient of the handlebar torque in steering, and generating a time domain compensation factor of the seat cushion displacement on a bumpy road; and the resonance confidence coefficient is generated through field coupling operation of the antinode space fidelity, the space verification tolerance coefficient and the time domain compensation factor.
[0053] The energy convergence judgment subcomponent is used for correlating the anti-node time domain convergence factor with the riding energy dissipation ground state, modulating the attenuation reference line of the wind speed gradient, and compensating the environmental disturbance of the tire ground noise generation; and the energy convergence factor is output through dynamic calibration of the anti-node time domain convergence factor, the attenuation reference line and the environmental disturbance compensation.
[0054] The double-factor combined triggering subcomponent is used for performing tensor product operation on the resonance confidence coefficient and the energy convergence factor in the motion constraint space, mapping the space distribution of the confidence coefficient to the geometric constraint space, and converting the time domain change of the convergence factor to the energy dissipation constraint; when the intersection volume of the geometric constraint space and the energy dissipation constraint exceeds a critical threshold, a stress standing wave topology locking signal is generated, and it is judged that the energy node distribution is effective.
[0055] In the above embodiment, the dynamic resonance verification component of the embodiment realizes accurate control of the frame vibration energy through multi-dimensional collaborative detection. The spatial consistency quantization subcomponent establishes a spatial dimension evaluation reference for the antinode distribution, the time domain attenuation correlation subcomponent constructs a time domain evaluation standard for energy attenuation, and the two form orthogonal detection dimensions to ensure that the vibration energy distribution meets the spatial topology requirements and the time domain attenuation characteristics at the same time. Through real-time adjustment of the space verification tolerance coefficient and the time domain compensation factor, the system has the ability to adapt to changes in riding posture and road excitation, and maintains the dynamic stability of the verification standard. Field coupling operation realizes interactive verification of the stress standing wave field, the mechanical load field and the displacement field, tensor product operation unifies the geometric constraint and the energy constraint to the motion constraint space, and a multi-dimensional parameter correlation model is established. The intersection volume threshold triggering mechanism converts continuous detection quantities into discrete locking signals, and quantifies the overlap degree of the geometric constraint space and the energy dissipation constraint to objectively judge whether the vibration energy distribution reaches the ideal resonance state.
[0056] In summary, the embodiment outputs a binary decision result topology locking signal or distribution invalidity with clear physical meaning through a four-level processing flow of spatial distribution detection, time domain attenuation analysis, environmental disturbance compensation and multi-field coupling calculation, thereby providing a deterministic decision basis for frame resonance control.

[0064] In the above embodiments, the dual-factor combined trigger subassembly system of the present embodiment realizes precise control of the resonance energy of the bicycle frame through multi-dimensional constraint coupling and dynamic evaluation mechanism. The confidence distribution model of the frame structure is established through the spatial discretization module, and the time domain discretization module constructs the time reference of energy attenuation, which together forms a four-dimensional constraint body, three-dimensional space + time dimension. This collaborative constraint unifies the physical characteristics of the frame and the energy characteristics of the motion in the four-dimensional parameter space. The dissipation path embedding module dynamically adjusts the effective volume of the four-dimensional constraint body by comparing the reference dissipation channel with the actual energy trajectory in real time. The feedback mechanism enables the system to adapt to the energy distribution changes during cycling, maintaining the real-time effectiveness of the constraint conditions. The topological locking trigger module introduces the quantitative comparison of stable standing wave proportion and energy leakage rate. When the system meets the standing wave stability condition, the stable standing wave proportion > energy leakage rate x safety factor, the locking signal is triggered.

Both of them constitute the time-space separation quantization basis of authentication efficiency. The four-dimensional reference body construction unit innovatively takes the double-factor constraint volume as the reference framework, reflects the influence of frame dynamic deformation through the time-space expansion coefficient generated by strain field modulation, and combines the phase calibration vector of riding rhythm to construct a four-dimensional (3D space + time) dynamic reference system that can adapt to the change of riding state. The reference body provides a standardized coordinate system for subsequent authentication fusion. The authentication amount fusion unit uses manifold expansion and space projection technology to convert discrete time coverage authentication amount into continuous time manifold, and reconstructs the space-penetration authentication amount into a gridized space skeleton, and generates a fusion authentication body with complete four-dimensional characteristics through a time-space interlacing algorithm. This fusion method maintains the time-space topological relationship of the original authentication data. The critical volume determination unit introduces a time-space volume density integral algorithm, analyzes the intersection area between the fusion authentication four-dimensional body and the dynamic reference body, and converts the authentication effectiveness determination into a quantifiable time-space volume comparison (effective authentication volume to critical threshold). This determination method overcomes the limitations of traditional single-dimensional threshold determination.
[0082] In summary, the embodiment realizes a complete processing flow from discrete authentication data acquisition, time-space dimension separation quantization, dynamic reference construction, four-dimensional fusion, and volume determination, and finally outputs an energy node distribution effectiveness judgment with clear physical meaning, providing a core decision basis for precise control of the riding biological energy system.

[0102] Step S100: When an electric bicycle rider makes a sound, the tubular conduction ripples of the sound waves within the frame structure of the electric bicycle are collected; a dynamic boundary waveguide mechanism is constructed by analyzing the multiphase damped oscillations formed by the sound waves at the contact points between the tube wall of the frame structure and the rider. The dynamic boundary waveguide mechanism transforms the frame structure into an acoustic transmission line with an elastic structural fingerprint, and its waveguide characteristics integrate the frame structure geometry and the rider's biomechanical characteristics.
[0103] Step S200: Based on the output elastic structure fingerprint, an intrinsic vibration spectrum of the frame structure is generated. The intrinsic vibration spectrum of the frame structure is modulated by the resonant mode of the frame structure material and the rider's contact stiffness. The structural carrier resonance is excited only when the sound frequency matches a specific mode. The rider needs to resonate at the sound frequency of the structural carrier resonance to generate energy node distribution at the handlebars or seat.
[0104] Step S300: Input the generated energy node distribution into the motion entropy processor and generate a cycling soundprint entropy field based on the riding state; map the parameters of the cycling soundprint entropy field to the deformation tolerance of the preset human-vehicle coupling constraint domain, and trigger unlocking when the tolerance interval converges to a threshold;

When the rider speaks, the sound wave forms a multi-phase damping oscillation modulated by the biomechanical parameters in the frame, which is converted into an elastic structure fingerprint containing the coupling characteristics of the rider and the vehicle through a dynamic boundary waveguide mechanism. The fingerprint excites the structure carrier resonance of a specific mode in the intrinsic vibration spectrum of the frame, and forms energy nodes with spatial and temporal distribution characteristics at key parts of the vehicle body. Through the motion entropy processor, parameters such as the migration trajectory of the energy node, the intensity distortion, and the phase difference of the environmental noise are analyzed in real time, a multi-dimensional feature space of the riding voiceprint entropy field is constructed, and finally the unlocking decision is realized through the deformation tolerance matching of the human-vehicle coupling constraint domain. The frame structure and the human characteristics are used as an integral and indivisible part of the overall acoustic system, and the synergistic effect of structural resonance and biomechanics is used to realize high-security non-contact authentication.
