Description

Technical Field

[0001] This invention belongs to the field of intelligent transportation and Internet of Things technology, specifically a two-wheeled vehicle intelligent three-dimensional parking system that integrates wireless charging and anti-theft positioning. Background Technology

[0002] With the acceleration of urbanization and the rapid increase in the number of two-wheeled vehicles (such as electric bicycles and motorcycles), the parking and charging management of these vehicles has become a crucial issue to be addressed in urban transportation. On the one hand, limited urban space makes traditional planar parking methods for two-wheeled vehicles insufficient to meet the growing parking demand. Multi-level parking systems, with their advantage of efficient space utilization, are gradually gaining attention and are beginning to be applied in two-wheeled vehicle parking scenarios. On the other hand, the demand for convenient charging for electric two-wheeled vehicles is becoming increasingly prominent. Wireless charging technology, as a convenient and relatively safe charging method that eliminates the need for plugging and unplugging charging cables, has shown promising application prospects in the field of two-wheeled vehicle charging.

[0003] For example, the invention disclosed in CN117513838A, entitled "Two-Wheeled Vehicle High-Low Nested Parking System and Two-Wheeled Vehicle Vertical Circulation Three-Dimensional Parking Garage," includes a drive unit and several horizontal and tilting parking units placed side-by-side and nested within each other. The drive wheel of the horizontal parking unit drives the first transmission unit to move the low-position traction frame linearly back and forth, allowing the horizontal two-wheeled vehicle to move longitudinally horizontally into the parking space. The high-position traction frame of the tilting parking unit moves the traction clamp upwards, tilting the two-wheeled vehicle. The drive wheel of the tilting parking unit drives the first transmission unit to move the high-position traction frame linearly back and forth, allowing the tilted two-wheeled vehicle to move longitudinally horizontally into the parking space. The drive unit controls the energization of each electromagnetic clutch, driving each drive wheel to rotate, thus realizing the "parking" or "retrieval" of each parking unit. This invention offers advantages such as safe, fast, and orderly vehicle parking, increased parking capacity within the same area, widespread applicability to two-wheeled vehicle parking lots, and convenient intelligent management.

[0004] However, in existing technologies, mainstream anti-theft positioning solutions achieve their functions through "GPS / BeiDou positioning chip + IoT module + vibration sensor": the positioning chip collects vehicle location data in real time, the IoT module uploads the data to the cloud platform, and when the vibration sensor detects abnormal vibrations (such as lock picking or moving), the system triggers an audible and visual alarm and pushes location information to the owner's mobile phone. However, such solutions are mostly "externally added" and are not deeply integrated with multi-level parking systems and wireless charging modules. In practical applications, there are two major contradictions: First, the metal frame structure of multi-level parking garages can block GPS signals, resulting in a decrease in positioning accuracy (the positioning error inside the garage often exceeds 5 meters, making it impossible to identify the specific parking level / location of the vehicle); second, the alternating electromagnetic field (frequency usually 100kHz-200kHz) generated when wireless charging is activated can cause strong interference to the signal receiving link of the positioning chip; the theft of two-wheeled vehicles is a prominent problem, and vehicle owners have a strong demand for anti-theft measures during vehicle parking. Anti-theft positioning systems can track vehicle locations in real time, promptly alerting owners to any abnormal movement and assisting in vehicle retrieval in the event of theft. Therefore, integrating anti-theft positioning functionality into two-wheeled vehicle parking scenarios is essential.

[0005] Based on the aforementioned application needs, a smart three-dimensional parking system for two-wheeled vehicles integrating wireless charging and anti-theft positioning functions has emerged. However, during actual research and development and application exploration, some technical problems have been discovered that need to be solved. Specifically, in terms of anti-theft positioning, since the wireless charging process relies on electromagnetic fields to achieve energy transfer, and this electromagnetic field generates a certain electromagnetic environment during operation, this electromagnetic environment may interfere with the signal of the anti-theft positioning system. The anti-theft positioning system mainly relies on key components such as positioning chips to receive and transmit signals to achieve accurate positioning and real-time transmission of location information. Once interfered with by the electromagnetic field of wireless charging, the signal reception and processing of the positioning chip may have errors, thus affecting the accuracy and stability of the entire positioning system. Therefore, to address the above problems, a smart three-dimensional parking system for two-wheeled vehicles integrating wireless charging and anti-theft positioning is proposed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a smart three-dimensional parking system for two-wheeled vehicles that integrates wireless charging and anti-theft positioning, thereby solving the technical problems mentioned in the background art.

[0007] To address the above technical problems, the following technical solution is adopted: a two-wheeled vehicle intelligent three-dimensional parking system integrating wireless charging and anti-theft positioning, the system including an electromagnetic environment adjustment module, a signal shielding optimization module, and a positioning compensation and correction module; the electromagnetic environment adjustment module is used to reduce the signal interference of the electromagnetic environment generated during wireless charging on the anti-theft positioning system by arranging multiple layers of electromagnetic shielding materials around the wireless charging device and dynamically adjusting the electromagnetic field strength.

[0008] The electromagnetic shielding material comprises a conductive fiber layer, a magnetic absorbing layer, and an insulating layer, which are fixed together by flexible connectors to form an integrated structure. The signal shielding optimization module monitors the signal reception strength of the anti-theft positioning chip in real time when the wireless charging device is activated, and adjusts the shielding parameters of the electromagnetic shielding material according to changes in signal strength. Specifically, this includes the shielding material thickness, the number of shielding layers, and the arrangement order of the shielding materials. (The parameter settings include the shielding material thickness, the number of shielding layers, and the arrangement order of the shielding materials.) These parameters are pre-configured based on the overall system's operating environment (such as indoor and outdoor environments, basements, etc.). Manual adjustments are made within the specific scenario of the entire system (i.e., the environment they configure is adjusted according to the environment; the settings for indoor and outdoor environments do not change arbitrarily after the system is set up).

[0009] The positioning compensation and correction module is used to correct the positioning data by means of a built-in error compensation algorithm when the signal error of the anti-theft positioning chip exceeds a preset threshold. At the same time, it generates a corrected positioning result by combining the three-dimensional coordinate information of the vehicle's physical location.

[0010] Preferably, the electromagnetic environment adjustment module further includes an electromagnetic field strength dynamic adjustment unit. The electromagnetic field strength dynamic adjustment unit calculates the optimal working intensity of the current electromagnetic field by collecting the power output data of the wireless charging device and the signal quality index of the anti-theft positioning chip, and feeds the intensity value back to the control unit of the wireless charging device, so that the control unit can perform the corresponding power adjustment operation.

[0011] Preferably, the signal shielding optimization module adjusts the shielding parameters in the following manner: First, after the wireless charging device is started, the signal reception strength data of the anti-theft positioning chip at different time points are collected, and these data are compared and analyzed with the preset standard signal strength range; second, if the signal strength is found to be lower than the standard range, the thickness or number of layers of electromagnetic shielding material is gradually increased until the signal strength is restored to the standard range; third, if the signal strength is higher than the standard range, the thickness or number of layers of electromagnetic shielding material is reduced, and the arrangement order of the shielding material is adjusted to ensure that the signal strength is maintained at the optimal state.

[0012] Preferably, the signal error correction processing of the anti-theft positioning chip includes: first, based on the original positioning data of the anti-theft positioning chip, extracting the main sources of signal error, including phase shift caused by electromagnetic interference, signal amplitude attenuation, and positioning deviation caused by multipath effect; second, for each source of error, using a corresponding error compensation algorithm for processing, such as using a phase correction algorithm to eliminate phase shift, using a gain amplification algorithm to compensate for signal amplitude attenuation, and using a multipath suppression algorithm to reduce the influence of multipath effect; finally, fusing the processed positioning data with the three-dimensional coordinate information of the vehicle's physical location to generate the final corrected positioning result.

[0013] Preferably, the positioning compensation and correction module further includes an error feedback unit, which is used to feed back the positioning error values ​​before and after correction to the electromagnetic environment adjustment module and the signal shielding optimization module after the positioning data correction is completed, so as to further optimize the parameter configuration of the electromagnetic shielding material and the dynamic adjustment strategy of the electromagnetic field strength.

[0014] Preferably, the positioning compensation and correction module further includes an anomaly alarm unit. The anomaly alarm unit is used to send an anomaly alarm message to the vehicle owner when the positioning error is detected to continuously exceed a preset threshold and cannot be completely corrected by the error compensation algorithm. At the same time, it records the time, location and relevant environmental parameters of the anomaly, so as to provide a basis for subsequent problem investigation.

[0015] Preferably, the step of feeding back the positioning error values ​​before and after correction to the electromagnetic environment adjustment module and the signal shielding optimization module includes: first, storing the positioning error values ​​before and after correction to designated data buffers respectively; second, sending the stored error values ​​to the electromagnetic environment adjustment module and the signal shielding optimization module through a data transmission interface; and third, the electromagnetic environment adjustment module adjusting the thickness and number of layers of the electromagnetic shielding material according to the received error values, and the signal shielding optimization module recalculating the optimal arrangement order of the shielding materials according to the error values.

[0016] The present invention also discloses an electronic device applied to any of the aforementioned intelligent three-dimensional parking systems for two-wheeled vehicles that integrate wireless charging and anti-theft positioning; the electronic device includes: at least one processor, a memory, and a computer program stored in the memory and capable of running on the at least one processor.

[0017] The beneficial effects of this invention are:

[0018] This invention presents an intelligent three-dimensional parking system for two-wheeled vehicles that integrates wireless charging and anti-theft positioning. By introducing an electromagnetic environment adjustment module, a signal shielding optimization module, and a positioning compensation and correction module, it effectively solves the problem of interference from the electromagnetic field of wireless charging to the anti-theft positioning system. The electromagnetic environment adjustment module reduces the impact of electromagnetic interference on signal transmission by dynamically adjusting the electromagnetic field strength and arranging multiple layers of electromagnetic shielding material. The signal shielding optimization module ensures that the signal quality is always at its optimal state by monitoring the signal strength in real time and adjusting the shielding parameters. The positioning compensation and correction module improves the accuracy and stability of the positioning results by correcting the positioning data through an error compensation algorithm. The synergistic effect of these technologies not only enhances the overall performance of the system but also provides a reliable guarantee for the efficient parking and secure anti-theft of two-wheeled vehicles.

[0025] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0026] Specific implementation examples are given below.

[0027] Example

[0028] Please see Figures 1-2 This invention provides a two-wheeled vehicle intelligent three-dimensional parking system that integrates wireless charging and anti-theft positioning, including an electromagnetic environment adjustment module 1, a signal shielding optimization module 2, and a positioning compensation and correction module 3, which includes a conductive fiber layer 4, a magnetic wave-absorbing layer 5, an insulating isolation layer 6, and a flexible connector 7.

[0029] In practical applications, the electromagnetic environment conditioning module 1 is located in the area surrounding the wireless charging device. It effectively controls electromagnetic interference generated during wireless charging by arranging multiple layers of electromagnetic shielding material. The electromagnetic shielding material consists of a conductive fiber layer 4, a magnetic absorbing layer 5, and an insulating isolation layer 6. The layers are fixed together by flexible connectors 7 to form an integrated structure.

[0030] The conductive fiber layer 4 is positioned near the wireless charging device to absorb high-frequency electromagnetic waves and convert them into heat energy. The magnetic absorbing layer 5 is located outside the conductive fiber layer 4 to absorb the energy of low-frequency magnetic fields. The insulating layer 6 serves as the outermost layer, blocking external electromagnetic interference. The flexible connector 7 is made of a highly elastic material. This material characteristic allows for a certain degree of deformability and relative displacement space between the shielding layers, providing a structural basis for parameter adjustment. For example, the shielding material layers can be moved by a preset mechanical adjustment mechanism (such as a telescopic component driven by a micro-motor), thereby changing the thickness of the shielding material (e.g., indirectly achieving equivalent thickness changes through adjusting the interlayer distance) or the number of layers (e.g., connecting or removing some spare shielding layers from the working area through a mechanical structure) to adapt to wireless charging devices of different shapes and sizes.

[0031] The "anti-interference capability" of shielding materials depends not only on the physical thickness of a single layer, but also on the "density of stacking" of multiple layers. When two layers of shielding materials are closer together (smaller interlayer distance), their magnetic / electric field blocking effects will be "superimposed and enhanced," thus increasing the equivalent shielding thickness. When two layers of shielding materials are farther apart (larger interlayer distance), the superposition effect weakens, the anti-interference capability decreases, which is equivalent to "reducing the equivalent shielding thickness." By adjusting the "interlayer distance" through mechanical structures, the "equivalent thickness" can be indirectly controlled.

[0032] Flexible connectors are elastic bands that can be stretched and retracted. Materials such as silicone strips, thin elastic fabrics (similar to the elastic fabrics used in sportswear), nylon elastic webbing, and flexible PVC strips can be selected.

[0033] At the edge of each layer of shielding material (leaving one mounting point on each side), use glue or small screws to fix the flexible connector between the two layers of shielding material. For example, stick a silicone strip to the lower edge of the conductive fiber layer, and stick the other end of the silicone strip to the upper edge of the magnetic absorbing layer. Like an elastic rope, it can both hold the two layers of shielding material together and allow the two layers of material to move back and forth / up and down (because the silicone strip can be stretched and shortened) without breaking due to movement.

[0034] The mechanical adjustment structure can be composed of a "micro stepper motor + slide rail + lead screw nut". The micro stepper motor is a motor smaller than a ping-pong ball, which can precisely rotate "small angles" (such as 1.8° each time) to provide the power for "pushing / pushing the shielding layer".

[0035] Fix the slide rail to the "shielding cover of the wireless charging device", then fix the "magnetic wave-absorbing layer" (intermediate shielding material) to the "nut". The motor and the lead screw are connected together and attached to one end of the slide rail. This is equivalent to "the motor driving the lead screw to rotate, and the nut carrying the magnetic wave-absorbing layer sliding back and forth on the slide rail".

[0036] Assuming the electromagnetic field of current wireless charging is too strong, weakening the signal of the anti-theft positioning chip, the system needs to "increase the equivalent shielding thickness." The specific steps are as follows:

[0037] Monitoring signal: The signal shielding optimization module found that "the positioning chip signal strength is -80dBm, which is lower than the standard range of -70~-60dBm", so it sent an instruction to the mechanical adjustment mechanism: "The equivalent thickness needs to be increased, and the magnetic absorbing layer should be pushed 2mm closer to the conductive fiber layer."

[0038] Motor operation: After receiving the command, the micro stepper motor rotates clockwise by a certain angle (e.g., 10 revolutions), and the lead screw rotates accordingly. The nut on the lead screw then moves along the slide rail towards the "conductive fiber layer" along with the "magnetic wave-absorbing layer".

[0039] At this point, the flexible connector between the two layers will be "compressed" (because the distance between the two layers becomes smaller), but the elasticity of the flexible connector will keep the two layers close together and prevent them from becoming loose.

[0040] The original distance between the two layers was 5mm, but now it has become 3mm, thus increasing the effective shielding thickness.

[0041] Stop adjustment: The signal shielding optimization module monitors the signal in real time. When the signal strength returns to -65dBm (within the standard range), it immediately sends a "stop" command to the motor. The motor stops rotating, and the shielding layer is fixed in position. The whole process takes less than 10 seconds and is completely automatic.

[0042] If the signal is too strong (e.g., -50dBm, exceeding the standard range), the reverse is applied: the motor rotates counterclockwise, the nut carries the magnetic absorbing layer away from the conductive fiber layer, the interlayer distance changes from 3mm back to 5mm, the equivalent thickness decreases, and the signal strength is reduced to the standard range.

[0043] The electromagnetic environment conditioning module 1 also includes an electromagnetic field strength dynamic adjustment unit, which calculates the optimal working strength of the current electromagnetic field by collecting the power output data of the wireless charging device and the signal quality index of the anti-theft positioning chip.

[0044] In practice, the electromagnetic field strength dynamic adjustment unit first obtains the real-time power output value of the wireless charging device, and at the same time monitors the signal reception strength of the anti-theft positioning chip.

[0045] When the signal reception strength is below a preset threshold, the dynamic adjustment unit reduces the output power of the wireless charging device to minimize the impact of electromagnetic interference on signal transmission. Conversely, if the signal reception strength is above the preset threshold, the output power of the wireless charging device is appropriately increased to ensure charging efficiency. This process is executed by the control unit of the wireless charging device, which adjusts the power output based on the optimal operating strength value fed back by the dynamic adjustment unit.

[0046] The signal shielding optimization module 2 and the electromagnetic environment adjustment module 1 work together, both aiming to "optimize the electromagnetic environment of the anti-theft positioning chip and ensure signal quality," and they interact with each other and coordinate functions. The electromagnetic environment adjustment module 1 dynamically adjusts the electromagnetic field strength, changing the electromagnetic environment of the anti-theft positioning chip and thus affecting its signal strength. The signal shielding optimization module 2 monitors signal strength changes in real time, and its decisions to adjust shielding parameters may require consideration of changes in electromagnetic field strength (e.g., if the electromagnetic field strength is too high, it may be necessary to further increase the shielding thickness or number of layers). Simultaneously, the parameter adjustments made by the signal shielding optimization module 2 may also have a feedback effect on the operation of the electromagnetic environment adjustment module 1 (e.g., after improving the shielding effect, the electromagnetic field strength dynamic adjustment unit can appropriately increase the wireless charging power). The error feedback unit of the positioning compensation and correction module 3 feeds back the positioning error values ​​before and after correction to both the electromagnetic environment adjustment module 1 and the signal shielding optimization module 2. The electromagnetic environment adjustment module 1 and the signal shielding optimization module 2 can adjust their own operating parameters according to the error feedback. For example, if the error feedback shows that the positioning error is still large, the electromagnetic environment adjustment module (1) can further reduce the electromagnetic field strength, and the signal shielding optimization module (2) can readjust the thickness, number of layers or arrangement order of the shielding material to form a closed loop of "monitoring-adjustment-feedback-readjustment". When the wireless charging device is started, the signal receiving strength of the anti-theft positioning chip is monitored in real time, and the parameter configuration of the electromagnetic shielding material is adjusted according to the change of signal strength. The thickness of the shielding material directly determines its ability to attenuate electromagnetic interference. The greater the thickness, the stronger the blocking effect of electromagnetic interference. When the electromagnetic interference generated by wireless charging is strong, if the thickness of the shielding material is insufficient, a large amount of electromagnetic interference will penetrate the shielding layer and interfere with the positioning signal received by the anti-theft positioning chip, resulting in a decrease in signal strength; conversely, if the thickness of the shielding material is too large, although it can effectively block electromagnetic interference, it may cause excessive attenuation of the positioning signal (such as GPS signal, Bluetooth signal, etc.) normally received by the anti-theft positioning chip, which also leads to a decrease in signal strength.

[0047] Specifically, the signal shielding optimization module 2 first collects signal reception strength data of the anti-theft positioning chip at different time points and compares and analyzes this data with a preset standard signal strength range. If the signal strength is found to be lower than the standard range, the thickness or number of layers of electromagnetic shielding material is gradually increased until the signal strength recovers to the standard range. For example, when the signal strength drops significantly, the thickness of the magnetic absorbing layer 5 can be increased or an additional conductive fiber layer 4 can be added on its outer side.

[0048] If the signal strength exceeds the standard range, the thickness or number of electromagnetic shielding materials is reduced, and the arrangement order of the shielding materials is adjusted. For example, when the signal strength is too high, the thickness of the insulating layer 6 can be reduced, or the magnetic absorbing layer 5 can be moved closer to the wireless charging device. The above adjustment process is automatically completed by the algorithm built into the signal shielding optimization module 2, without manual intervention.

[0049] The positioning compensation and correction module 3 is mainly used to handle signal error issues of the anti-theft positioning chip. When the signal error of the anti-theft positioning chip exceeds a preset threshold, the positioning compensation and correction module 3 corrects the positioning data through a built-in error compensation algorithm.

[0050] In practice, the main sources of signal error are first extracted from the raw positioning data of the anti-theft positioning chip, including phase shift caused by electromagnetic interference, signal amplitude attenuation, and positioning deviation caused by multipath effects. For each source of error, a corresponding error compensation algorithm is then used for processing.

[0051] For example, a phase correction algorithm is used to eliminate phase shift, a gain amplification algorithm is used to compensate for signal amplitude attenuation, and a multipath suppression algorithm is used to reduce the impact of multipath effects. After error compensation processing, the corrected positioning data is fused with the three-dimensional coordinate information of the vehicle's physical location to generate the final corrected positioning result. The positioning compensation and correction module 3 also includes an error feedback unit and an anomaly alarm unit. After completing the positioning data correction, the error feedback unit stores the positioning error values ​​before and after correction in a designated data buffer and sends them to the electromagnetic environment adjustment module 1 and the signal shielding optimization module 2 through the data transmission interface.

[0052] The electromagnetic environment adjustment module 1 adjusts the thickness and number of layers of the electromagnetic shielding material based on the received error value, while the signal shielding optimization module 2 recalculates the optimal arrangement order of the shielding materials based on the error value. When the anomaly alarm unit detects that the positioning error continuously exceeds a preset threshold and cannot be completely corrected by the error compensation algorithm, it sends an anomaly alarm message to the vehicle owner and records the time, location, and relevant environmental parameters of the anomaly, providing a basis for subsequent troubleshooting.

[0053] In practical applications, the system operates as follows: when a two-wheeled vehicle is parked in the intelligent three-dimensional parking system, the wireless charging device starts working, and at the same time, the anti-theft positioning chip enters the signal monitoring state.

[0054] Electromagnetic environment conditioning module 1 reduces electromagnetic interference generated during wireless charging by arranging multiple layers of electromagnetic shielding material and dynamically adjusting the electromagnetic field strength. Signal shielding optimization module 2 monitors the signal reception strength of the anti-theft positioning chip in real time and adjusts the parameter configuration of the electromagnetic shielding material according to changes in signal strength.

[0055] When the positioning compensation and correction module 3 detects that the signal error of the anti-theft positioning chip exceeds the preset threshold, it corrects the positioning data through the built-in error compensation algorithm and feeds back the positioning error values ​​before and after correction to the electromagnetic environment adjustment module 1 and the signal shielding optimization module 2, so as to further optimize the parameter configuration of the electromagnetic shielding material and the dynamic adjustment strategy of the electromagnetic field strength.

[0056] Through the synergistic effect of the above modules, the entire system achieves a high degree of integration between wireless charging and anti-theft positioning functions, effectively solving problems such as low space utilization efficiency and the impact of electromagnetic interference from wireless charging on the accuracy of anti-theft positioning.

[0057] In terms of electronic equipment, this system also includes at least one processor, a memory, and a computer program stored in the memory and capable of running on the processor. The processor is responsible for executing the functional instructions in the electromagnetic environment adjustment module 1, the signal shielding optimization module 2, and the positioning compensation and correction module 3. The memory is used to store the data and program code required for system operation.

[0058] The above content describes in detail the specific embodiments of the present invention, and fully discloses the composition, connection relationship and operating principle of each module, so as to ensure that those skilled in the art can implement the technical solution according to the contents of the specification.

[0059] To enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention will be further explained below in conjunction with a specific application scenario.

[0060] When a two-wheeled vehicle enters the intelligent automated parking system, it is first guided by a mechanical device to park in the designated charging and positioning area. At this time, the wireless charging device starts working, and the anti-theft positioning chip enters signal monitoring mode. The electromagnetic environment adjustment module 1 begins to operate, and the multi-layer electromagnetic shielding material arranged around the wireless charging device then takes effect.

[0061] The conductive fiber layer 4 absorbs high-frequency electromagnetic waves and converts them into heat energy; the magnetic absorbing layer 5 absorbs the energy of low-frequency magnetic fields; the insulating layer 6, as the outermost layer, blocks external electromagnetic interference. The flexible connector 7 ensures a tight fit between the layers, adapting to changes in the shape and size of the wireless charging device.

[0062] Meanwhile, the electromagnetic field strength dynamic adjustment unit collects the power output data of the wireless charging device and the signal reception strength of the anti-theft positioning chip. If the signal reception strength is lower than a preset threshold, the output power of the wireless charging device is reduced to reduce electromagnetic interference; conversely, the output power is appropriately increased to ensure charging efficiency.

[0063] After the wireless charging device is activated, the signal shielding optimization module 2 monitors the signal reception strength of the anti-theft positioning chip in real time. For example, at a certain moment, the signal reception strength of the anti-theft positioning chip is -80dBm, while the preset standard signal strength range is -70dBm to -60dBm. Since the signal strength is lower than the standard range, the signal shielding optimization module 2 gradually increases the thickness or number of layers of electromagnetic shielding material. Specifically, the thickness of the magnetic absorbing layer 5 can be increased, or an additional conductive fiber layer 4 can be added on its outer side. If the signal strength is higher than the standard range, the thickness or number of layers of electromagnetic shielding material is reduced, and the arrangement order of the shielding material is adjusted.

[0064] For example, the thickness of the insulating layer 6 can be reduced, or the magnetic absorbing layer 5 can be moved closer to the wireless charging device. These adjustments are automatically performed by the algorithm built into the signal shielding optimization module 2, requiring no manual intervention.

[0065] During signal monitoring, if the positioning compensation and correction module 3 detects that the signal error of the anti-theft positioning chip exceeds a preset threshold, for example, an error of 5 meters, exceeding the system's allowable error range of 2 meters, then the error compensation algorithm is activated to correct the positioning data. First, based on the original positioning data from the anti-theft positioning chip, the main sources of signal error are extracted, including phase shift caused by electromagnetic interference, signal amplitude attenuation, and positioning deviation caused by multipath effects. For each source of error, a corresponding error compensation algorithm is used for processing.

[0066] For example, a phase correction algorithm is used to eliminate phase shift, a gain amplification algorithm is used to compensate for signal amplitude attenuation, and a multipath suppression algorithm is used to reduce the impact of multipath effects. After error compensation processing, the corrected positioning data is fused with the three-dimensional coordinate information of the vehicle's physical location to generate the final corrected positioning result. The error feedback unit stores the positioning error values ​​before and after correction in a designated data buffer and sends them to the electromagnetic environment adjustment module 1 and the signal shielding optimization module 2 through the data transmission interface. The electromagnetic environment adjustment module 1 adjusts the thickness and number of layers of the electromagnetic shielding material according to the received error values, while the signal shielding optimization module 2 recalculates the optimal arrangement order of the shielding materials based on the error values.

[0067] If the abnormal alarm unit in the positioning compensation and correction module 3 detects that the positioning error continues to exceed the preset threshold and cannot be completely corrected by the error compensation algorithm, it sends an abnormal alarm message to the vehicle owner.

[0068] For example, when the positioning error remains above 8 meters for 10 consecutive minutes, the abnormal alarm unit sends an alarm notification to the vehicle owner's mobile phone through the wireless communication module. At the same time, it records the time and location of the abnormality and relevant environmental parameters, such as electromagnetic field strength and shielding material configuration, to provide a basis for subsequent troubleshooting.

[0069] Through the synergistic effect of the aforementioned modules, the entire system achieves a high degree of integration between wireless charging and anti-theft positioning functions. Electromagnetic environment adjustment module 1 reduces the impact of electromagnetic interference on signal transmission by dynamically adjusting the electromagnetic field strength and arranging multiple layers of electromagnetic shielding material; signal shielding optimization module 2 ensures optimal signal quality by monitoring signal strength in real time and adjusting shielding parameters; and positioning compensation and correction module 3 improves the accuracy and stability of positioning results by correcting positioning data using an error compensation algorithm. The synergistic effect of these technologies not only enhances the overall performance of the system but also provides reliable guarantees for efficient parking and secure anti-theft of two-wheeled vehicles.

[0070] In terms of electronic equipment, the processor is responsible for executing the various functional instructions in the electromagnetic environment adjustment module 1, the signal shielding optimization module 2, and the positioning compensation and correction module 3, while the memory is used to store the data and program code required for system operation.
