Detailed Implementation

[0027] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The following description, with reference to the accompanying drawings, describes a method, apparatus, electronic device, and storage medium for transmitting a cross-medium synthesized waveform based on a rotating permanent magnet array antenna according to embodiments of this application. Addressing the problems mentioned in the background art, this application provides a method for transmitting a cross-medium synthesized waveform based on a rotating permanent magnet array antenna. In this method, firstly, cross-medium transmission condition data of the rotating permanent magnet array antenna is acquired, including distance data from the antenna center point to the signal receiving point, dielectric layer data, the target magnetic field waveform received at the receiving point, and the conditions satisfying the target magnetic field waveform. This provides a precise basis for subsequent antenna parameter design and structure determination, avoiding subsequent design deviations due to missing or inaccurate data. Secondly, the number of antenna elements and the angular frequency of each element are determined based on the target magnetic field waveform and its satisfying conditions. By combining distance data, dielectric layer data, and the angular frequency of each array element, the volume of each element is determined. Through multi-dimensional data linkage calculations, the element parameters are ensured to be highly adapted to the cross-medium transmission scenario, laying the foundation for subsequent element structure design and overall antenna performance optimization. Finally, the structure of each element is determined based on its volume, and then the target structure of the antenna is determined based on the element structure. The rotating permanent magnet array antenna with this target structure is then used to transmit a cross-medium synthesized waveform, achieving a closed loop from parameter calculation to structure implementation to signal transmission. This ensures the effective transmission of the cross-medium synthesized waveform and improves the antenna's transmission reliability and adaptability in cross-medium scenarios. This solves the problems of complex low-frequency electromagnetic transmission structures and excessive energy consumption in large-scale cross-medium information transmission scenarios. Specifically, Figure 1 This is a flowchart illustrating a cross-medium synthesized waveform transmission method based on a rotating permanent magnet array antenna, as provided in an embodiment of this application.

[0029] like Figure 1 As shown, the cross-medium synthesized waveform transmission method based on a rotating permanent magnet array antenna includes the following steps: In step S101, the cross-medium transmission condition data of the rotating permanent magnet array antenna is obtained. The cross-medium transmission condition data includes the distance data from the center point of the rotating permanent magnet array antenna to the signal receiving point, the dielectric layer data, the target magnetic field waveform received by the receiving point, and the conditions for the target magnetic field waveform to be satisfied.

[0030] The rotating permanent magnet array antenna is a cooperative antenna system composed of multiple rotatable permanent magnets. It converts mechanical energy into electromagnetic energy to transmit signals by controlling the rotation of the array elements. An array element is the basic transmitting or receiving unit that makes up the entire antenna array. Cross-medium transmission condition data is the key set of fundamental data required for signal transmission across media. Dielectric layer data refers to the key parameters of the medium through which the signal penetrates from the transmitter to the receiver, including electromagnetic properties such as the type, thickness, and dielectric constant of the medium. The receiving point is the location of the terminal equipment used to receive electromagnetic signals in a cross-medium transmission scenario. The target magnetic field waveform is the desired signal shape at the receiving point, expressed as a change in magnetic field strength over time; it is the target result that the transmission scheme aims to achieve. The conditions for the target magnetic field waveform to effectively carry information are constraints that ensure the waveform carries the necessary information, such as amplitude range and frequency stability. Only when these conditions are met can cross-medium transmission be considered effective.

[0031] It is understood that the embodiments of this application can fully grasp the propagation environment and reception status during cross-medium transmission, and achieve accurate modeling and calibration of the attenuation, phase shift and other characteristics of the signal in different medium layers. In this way, the transmission amplitude, phase or waveform can be dynamically adjusted according to the actual path conditions to compensate for the distortion caused by the medium, improve the effective strength and signal-to-noise ratio of the receiver signal, and enhance the stability and reliability of communication or sensing.

[0032] In one embodiment of this application, the distance data includes the horizontal and vertical distances from the center point of the rotating permanent magnet array antenna to the signal receiving point, and the dielectric layer data includes the number of dielectric layers and the electromagnetic parameters of each dielectric layer.

[0033] Understandably, by obtaining the horizontal and vertical distances from the center point of the rotating permanent magnet array antenna to the signal receiving point, the spatial relationship between the antenna and the receiving point can be accurately described, providing a reference for subsequent signal strength calculation, path loss estimation, and waveform synthesis. At the same time, recording the number of medium layers and the electromagnetic parameters of each layer can reflect the influence of the medium during signal propagation, such as refraction, attenuation, and reflection.

[0034] like Figure 2 As shown in the embodiments of this application, the distance data includes the horizontal distance from the center point of the rotating permanent magnet array antenna to the signal receiving point. l and vertical distance d .in, This represents the distance from the information source to the interface between the first and second layers of the medium. ( m It is an integer and 1 < m < M ) indicates the first m Depth of the layer medium, Indicates the distance from the receiving point to the (th) M -1) Layer and the M The distance between the dielectric layers. Dielectric layer data includes the conductivity of each dielectric layer. magnetic permeability and dielectric constant Iso-electromagnetic parameters, which are usually considered to be constants, among which, In particular, when M When =1, it indicates that the source is transmitting the message in a single medium.

[0035] In step S102, the number of array elements and the angular frequency of each array element of the rotating permanent magnet array antenna are determined according to the target magnetic field waveform and the conditions that the target magnetic field waveform satisfies. The volume of each array element is determined according to the distance data, the dielectric layer data and the angular frequency of each array element.

[0036] Among them, the element angular frequency is the angular frequency at which the magnetic field changes during the rotation or oscillation of each element, determining the rate at which the magnetic field changes with time. The element volume is the physical size or volume of each element, affecting the strength and coverage of the magnetic field it generates.

[0037] Understandably, by determining the number of elements and angular frequency of the rotating permanent magnet array antenna based on the target magnetic field waveform and the conditions it meets, and by combining distance data and dielectric layer data to determine the volume of each element, the magnetic field emission characteristics of the antenna can be optimized. This ensures that the generated synthetic magnetic field waveform is highly consistent with the expected target waveform, improving the directionality and intensity distribution uniformity of the magnetic field. Simultaneously, it allows each element to generate a suitable magnetic field strength when penetrating different media, guaranteeing that the magnetic sensor at the receiving point can accurately receive the signal, thereby improving signal receptivity and reliability and reducing waveform distortion. Furthermore, by rationally designing the number, frequency, and volume of elements, unnecessary magnetic field redundancy output can be reduced, lowering energy consumption.

[0038] In one embodiment of this application, the condition for satisfying the target magnetic field waveform includes the minimum value of the magnetic field strength that can be received, determined by the sensitivity of the magnetic sensor configured at the receiving point. 、 And the range of magnetic field distortion rate when the receiving point device is triggered to work.

[0039] Understandably, by setting the minimum magnetic field strength and allowable magnetic field distortion rate range for the target magnetic field waveform, it is possible to ensure that the receiving point magnetic sensor can still effectively detect signals in complex environments, avoiding missed detections or false triggers due to weak signals or excessive distortion. Simultaneously, this condition can be used to optimize transmission parameters and adjust control strategies, thereby improving the reliability and positioning accuracy of cross-medium signal transmission.

[0040] In this application, the input is the target magnetic field waveform received at the receiving point. G 0(t Specific conditions must be met to ensure that the receiving device can correctly identify the signal. Two conditions are specifically set: First, the minimum acceptable magnetic field strength B 0, determined by the sensitivity of the magnetic sensor configured at the receiving point, meaning the magnetic field strength must be greater than or equal to... B Only when the magnetic field strength is 0 can it be detected by the sensor. For example, if the sensitivity of the magnetic sensor is 10 nT, the receiving device will not be able to recognize the signal if the magnetic field strength is lower than 10 nT.

[0041] Second, the magnetic field distortion rate range is used to control the triggering conditions of the receiving equipment. For example, in underwater torpedo applications, if the total harmonic distortion rate of the magnetic field waveform received by the torpedo's magnetic sensor meets the following conditions... If the signal is normal, the torpedo is triggered to execute its action; if Below or higher This indicates that the signal may be interfered with or distorted, and the torpedo remains silent and does not perform any actions. By introducing the determination of magnetic field distortion rate, false triggering or missed triggering can be effectively avoided, improving the reliability and safety of signal transmission in complex environments.

[0042] In one embodiment of this application, determining the number of array elements and the angular frequency of each array element of the rotating permanent magnet array antenna based on the target magnetic field waveform and the conditions satisfied by the target magnetic field waveform includes: performing Fourier decomposition on the target magnetic field waveform, determining the angular frequency of each array element based on the decomposition result, and determining the number of array elements of the rotating permanent magnet array antenna based on the conditions satisfied by the target magnetic field waveform.

[0043] Fourier decomposition decomposes a complex time-domain signal into a superposition of sine and cosine waves of different frequencies, which is used to analyze the frequency components of the target magnetic field waveform and thus determine the angular frequency of the array element.

[0044] It is understood that the embodiments of this application can reasonably determine the number of array elements and the angular frequency of each array element of the rotating permanent magnet array antenna according to the frequency characteristics of the target magnetic field waveform and the receiving conditions, thereby ensuring that the magnetic field output by the antenna can meet the sensitivity and distortion requirements of the receiving point, while avoiding resource waste or signal distortion caused by too many or too few array elements.

[0045] In one embodiment of this application, the Fourier decomposition formula of the target magnetic field waveform is:

[0046] in, , This is a magnetic field waveform function. For time, The fundamental angular frequency of the target magnetic field. The first of the target magnetic field n The amplitude of each frequency component, The first of the target magnetic field n The initial phase of each frequency component, The first of the target magnetic field n The angular frequency of each frequency component. N To determine the number of array elements.

[0047] It is understood that, by performing Fourier decomposition on the target magnetic field waveform, the embodiments of this application can clearly extract the various frequency components of the magnetic field signal, as well as their amplitude and phase, thereby providing a precise basis for determining the number of array elements and the angular frequency of each array element of the rotating permanent magnet array antenna.

[0048] In this application, when determining the number of array elements in a rotating permanent magnet array antenna, the target magnetic field waveform is first analyzed. Fourier decomposition is performed to obtain the amplitude and initial phase of each frequency component, thus yielding the corresponding angular frequency; then, based on the target magnetic field waveform conditions required for cross-medium transmission, an appropriate number of array elements is selected. N That is, satisfying when hour, ,and This ensures that the magnetic field waveform generated by the rotating permanent magnet array antenna meets the set target waveform, while simultaneously guaranteeing that the magnetic field distortion rate is within the set range. This method ensures that the array antenna can achieve both precise magnetic field control and meet the reception conditions of the receiving point during cross-medium transmission.

[0049] In one embodiment of this application, determining the volume of each array element based on distance data, dielectric layer data, and the angular frequency of each array element includes: determining a preset value based on the distance data; ensuring that the maximum geometric dimension of the center-to-edge distance of the rotating permanent magnet array antenna is less than the preset value; calculating the magnetic fields generated by the horizontal and vertical dipole sources in the transmedium based on the dielectric layer data and the angular frequency of each array element; superimposing the magnetic fields generated by the horizontal and vertical dipole sources in the transmedium to calculate the magnetic fields generated by each array element at the receiving point; determining the magnetic moment of each array element based on the quantitative relationship database of the array elements at the receiving point and the magnetic fields generated by each array element at the receiving point; and calculating the volume of each array element based on the magnetic moments and the permanent magnet material of the rotating permanent magnet array antenna.

[0050] In this embodiment of the application, the preset value determined based on distance data is... d1 / 10. A horizontal dipole source is an idealized electromagnetic source that generates a magnetic field in the horizontal direction, used to simulate the transmission characteristics of rotating permanent magnet array antenna elements in the horizontal direction. A vertical dipole source is an idealized electromagnetic source that generates a magnetic field in the vertical direction, used to simulate the transmission characteristics of rotating permanent magnet array antenna elements in the vertical direction. Magnetic moment is a physical quantity describing the strength and direction of the magnetism of a rotating permanent magnet array antenna element, used to calculate the magnetic field generated by the element at the receiving point.

[0051] Understandably, by combining distance data, dielectric layer data, and array element angular frequency, the magnetic field generated by each array element at the receiving point can be accurately calculated, and the magnetic moment and volume of the array element can be determined accordingly. This ensures that the geometric dimensions of the array elements meet the preset limits, so that the magnetic field transmitted by the array antenna in a cross-medium environment can meet the design requirements. This improves the accuracy and controllability of cross-medium transmission and provides a reliable basis for the efficient design of rotating permanent magnet array antennas. At the same time, by superimposing the magnetic field calculations of horizontal dipole sources and vertical dipole sources, accurate estimation of the array element magnetic field in complex environments can be quickly achieved.

[0052] The specific method for determining the volume of each array element in this embodiment is as follows: First, ensure that the maximum geometric dimension of the distance from the center of the array antenna to its edge is smaller than a preset value determined based on distance data: d 1 / 10, at this point the magnetic field generated by each array element at the receiving point Available Figure 3 The horizontal dipole source shown and vertical dipole source The magnetic fields generated across the medium are superimposed and calculated. Let be the magnetic moment of this array element. The rotation angular frequency of this array element. The angle between the magnetic moment direction of the array element and the normal direction of the medium interface is given.

[0053] Secondly, establish the magnetic field strength of the array element at the receiving point. and , , A database of quantitative relationships between them.

[0054] Next, according to Database, search for what satisfies , , of The value is the first one. The magnetic moment of each array element.

[0055] Finally, based on the magnetic moment Equal to the magnetization of permanent magnet materials With respect to the volume of permanent magnet materials The product of: = Once the user selects the permanent magnet material, Given that, and based on step ③ The value can then determine the first Volume of each element = .

[0056] In one embodiment of this application, the calculation formula for the quantitative relational database is:

[0057] in, The magnetic field strength of the array element at the receiving point. P Let be the magnetic moment of this array element. The rotation angular frequency of this array element. The angle between the magnetic moment direction of the array element and the normal direction of the medium interface is given.

[0058] Understandably, this can be achieved by establishing a function. This allows for precise quantification of the relationship between the magnetic field generated by each array element at the receiving point and its magnetic moment, rotational angular frequency, and magnetic moment direction, enabling quantitative analysis of array element performance. With this quantitative relationship, the required magnetic moment for each array element can be calculated in reverse. Thus, the volume of the array elements is determined. = This ensures that the design meets the target magnetic field waveform requirements.

[0059] In step S103, the structure of each array element is determined according to the volume of each array element, the target structure of the rotating permanent magnet array antenna is determined according to the structure of each array element, and the rotating permanent magnet array antenna with the target structure is used to transmit a trans-dielectric synthesized waveform.

[0060] The target structure is a complete rotating permanent magnet array antenna design based on the combination of various array elements. This includes the spatial arrangement of the elements, their installation angles, and overall geometric dimensions. This ensures that the array antenna can generate the expected cross-medium synthesized waveform during rotation. The cross-medium synthesized waveform is a predetermined magnetic field waveform formed at the receiving point after being transmitted by the rotating permanent magnet array antenna and passing through different dielectric layers. This waveform is used to achieve effective signal transmission and target detection.

[0061] It is understandable that by transforming the volume of each array element into a specific array element structure and further forming a complete rotating permanent magnet array antenna target structure, the array antenna can accurately transmit a predetermined cross-medium synthetic waveform during rotation, thereby ensuring the effectiveness and stability of signal propagation in different medium layers, improving the controllability of the target magnetic field waveform and the receiving reliability of the receiver, and providing accurate and repeatable signal output for cross-medium communication or detection.

[0062] like Figure 4 As shown, in the embodiments of this application, the structure of each array element can adopt a cylindrical permanent magnet, with the magnetization direction along the axial direction and the volume determined above. (Other shapes of permanent magnets can also be selected). Each permanent magnet is encased in a shell with a rotating shaft connected to a motor, which controls the rotation of the magnet element. For example... Figure 5 As shown, the structure of an array antenna can consist of multiple array elements, for example, four array elements evenly distributed in an array. On a circle centered at a point on the axis, the first... The magnetization direction of each element and The included angle of the axis is The control center controls the synchronous rotation of each array element motor and sets the rotation speed to [value missing]. This forms a target rotating permanent magnet array antenna, enabling the transmission of cross-medium synthesized waveforms.

[0063] In summary, the embodiments of this application, from basic condition input to gradually determining the key parameters and structure of array elements, and finally integrating them to obtain the array antenna structure, follow the specific process as follows: Figure 6 As shown: In step S601, the input transmedium wave condition is the starting point of the design, providing a basis for the subsequent performance design of the antenna in a transmedium environment.

[0064] In step S602, the number of array elements in the rotating permanent magnet array antenna is determined. The number of array elements directly affects the antenna's radiation performance, coverage range, and other key indicators, and is an important parameter setting step in the array antenna design.

[0065] In step S603, the angular frequency of each array element is determined. The angular frequency is related to the antenna's operating frequency and other characteristics. Different angular frequency settings allow the antenna to function within a specific electromagnetic frequency range.

[0066] In step S604, the volume of each array element is determined. The volume of the array element is related to the magnetic energy storage of the permanent magnet, the space occupation, and the coordination with other components. This is a planning of the antenna array elements from the perspective of physical dimensions.

[0067] In step S605, the structure of each array element is determined. The design of the array element structure will affect the magnetic field distribution and mechanical stability of the permanent magnet, and thus affect the performance of the entire array antenna.

[0068] In step S606, the structure of the array antenna is determined. After completing the relevant parameters and structural design of each array element, all array elements are integrated to determine the final structure of the entire rotating permanent magnet array antenna, so that the antenna can work as expected under trans-dielectric wave conditions.

[0069] According to the cross-medium synthesized waveform transmission method based on a rotating permanent magnet array antenna proposed in this application, firstly, the cross-medium transmission condition data of the rotating permanent magnet array antenna is obtained, including the distance data from the center point of the antenna to the signal receiving point, the dielectric layer data, the target magnetic field waveform received at the receiving point, and the conditions that the target magnetic field waveform meets. This provides a precise basis for subsequent antenna parameter design and structure determination, avoiding subsequent design deviations due to missing or inaccurate data. Secondly, the number of antenna elements and the angular frequency of each element are determined based on the target magnetic field waveform and its meeting conditions. Then, the distance data and dielectric layer data are combined with the dielectric layer data. The volume of each array element is determined by layer data and the angular frequency of each element. Through multi-dimensional data linkage calculation, the element parameters are ensured to be highly adapted to the cross-medium transmission scenario, laying the foundation for subsequent element structure design and overall antenna performance optimization. Finally, the structure of each array element is determined based on its volume, and then the target structure of the antenna is determined based on the structure of each element.

[0081] It should be noted that the foregoing explanation of the cross-medium synthesized waveform transmission method based on a rotating permanent magnet array antenna also applies to the cross-medium synthesized waveform transmission device based on a rotating permanent magnet array antenna in this embodiment, and will not be repeated here.

[0082] According to the cross-medium synthesized waveform transmitting device based on a rotating permanent magnet array antenna proposed in this application, firstly, the cross-medium transmission condition data of the rotating permanent magnet array antenna is acquired, including the distance data from the center point of the antenna to the signal receiving point, the dielectric layer data, the target magnetic field waveform received at the receiving point, and the conditions that the target magnetic field waveform meets. This provides a precise basis for subsequent antenna parameter design and structure determination, avoiding subsequent design deviations due to missing or inaccurate data. Secondly, the number of antenna elements and the angular frequency of each element are determined based on the target magnetic field waveform and its meeting conditions. Then, the distance data and dielectric layer data are combined with the dielectric layer data. The volume of each array element is determined by layer data and the angular frequency of each element. Through multi-dimensional data linkage calculation, the element parameters are ensured to be highly adapted to the cross-medium transmission scenario, laying the foundation for subsequent element structure design and overall antenna performance optimization. Finally, the structure of each array element is determined based on its volume, and then the target structure of the antenna is determined based on the structure of each element. The rotating permanent magnet array antenna with this target structure is then used to transmit a cross-medium synthesized waveform, realizing a closed loop from parameter calculation to structure implementation to signal transmission. This ensures the effective transmission of the cross-medium synthesized waveform and improves the antenna's transmission reliability and adaptability in cross-medium scenarios. This solves the problems of complex low-frequency electromagnetic transmission structures and excessive energy consumption in large-scale cross-medium information transmission scenarios.
