[0002] With the rapid development of 5G communications, aerospace electronics, and wearable technology, the need for electromagnetic interference shielding in non-uniform electromagnetic field environments is becoming increasingly complex. For example, within spacecraft cabins, in areas with high-density electronic equipment integration, or in flexible wearable devices, the electromagnetic field intensity distribution exhibits significant spatial gradient characteristics, making it difficult for traditional uniform shielding materials to achieve precise attenuation.

[0003] At present, to meet the needs of non-uniform electromagnetic field shielding, a representative solution is the design of a solid and liquid dual continuous conductive network based on a composite of MXene and liquid metal.

[0004] Although the above scheme has outstanding performance in shielding effectiveness and flexibility, it still has the following key defects: its shielding effectiveness depends on the static solid-liquid network structure, and it cannot dynamically adjust the porosity or resistance parameters according to the real-time electromagnetic field gradient, resulting in the risk of local shielding failure under non-uniform field strength; it involves multiple precision processes such as freeze-drying and polymerization treatment, which is difficult to mass produce and is costly; in extreme stretching or complex surface fitting scenarios, the liquid metal network is prone to interface fracture, resulting in interruption of the conductive path, and the shielding effectiveness is significantly reduced.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0023] In some of the processes described in the specification and claims of this application and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this document or may be executed in parallel.

In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this document are used to distinguish different messages, devices, modules, etc., and do not represent a sequential order, nor do they limit "first" and "second" to being different types.

[0024] The study found that among the current non-uniform electromagnetic field shielding technologies, although the solution based on liquid metal composite networks has high shielding effectiveness and basic flexibility, its solid-liquid bicontinuous structure has essential defects: the static conductive properties of the liquid metal network cannot respond to changes in spatial field strength gradients in real time, resulting in a mismatch between the shielding effectiveness distribution and the electromagnetic field strength; the multi-step freeze-drying and polymerization process leads to high preparation costs and difficulty in large-scale application; more importantly, in the case of tensile deformation or complex surface fitting, the liquid metal network causes the conductive path to be interrupted due to interface fracture, and the shielding effectiveness drops sharply.

[0025] In response to the above problems, this application proposes a method for dynamic deployment of a flexible interference network based on carbon fiber conductive cloth, which achieves breakthrough innovation through a four-dimensional control architecture of environmental compensation, gradient generation, deformation adaptation and resistance coordination. Specifically, first, the original field strength data is corrected by integrating temperature and humidity parameters to construct a high-precision compensation field strength model; secondly, the metal deposition process is driven based on the compensation data to generate a gradient pore structure, and the pore size distribution is adjusted in real time through deformation adaptation processing to solve the shielding failure caused by flexible deformation; further combined with pulse width modulation technology to dynamically adjust the regional grounding resistance to achieve closed-loop matching of electrical parameters and physical structure; finally, the impedance transition stability is guaranteed through the flexible integration of multi-level conductive dielectric layers. This method replaces the static network of liquid metal with dynamic control of gradient pores to control shielding fluctuations under tensile deformation; metal deposition and laser micromachining processes are used to reduce costs; through the coordinated mapping mechanism of aperture and resistance, the shielding effectiveness distribution and the spatial matching degree of the electromagnetic field gradient are improved, which completely overcomes the three major defects of the existing technology: insufficient dynamic response, complex process and poor deformation adaptability, and provides a highly reliable solution for flexible shielding in complex electromagnetic environments.

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0027] Figure 1 A flowchart of a method for deploying a flexible interference network based on carbon fiber conductive cloth is provided for the embodiment of the present application, such as Figure 1 As shown, the method includes: 101. Based on the detection unit arranged on the surface of the carbon fiber conductive cloth, obtain spatial field strength data in the non-uniform electromagnetic field environment, and perform physical field correction on the spatial field strength data in combination with the synchronously obtained ambient temperature and humidity parameters to obtain compensated field strength data; In this step, the detection unit refers to a sensor component integrated on the surface of the carbon fiber conductive cloth, which includes a field strength sensor and an environmental sensor, which are used to measure the electromagnetic field strength and environmental temperature and humidity parameters respectively.

[0028] Spatial field strength data refers to the distribution information of the electromagnetic field in three-dimensional space collected in real time by field strength sensors.

[0029] Physical field correction refers to the systematic error compensation of the original field strength data in combination with the environmental temperature and humidity parameters to eliminate the measurement deviation caused by environmental factors.

[0030] In an embodiment of the present application, first, a field intensity sensor scans the target area at a fixed frequency to generate a raw electromagnetic field intensity distribution map; simultaneously, an environmental sensor synchronously collects current temperature and humidity data. Secondly, a dielectric constant correction coefficient is calculated based on the temperature parameter, and a preliminary correction is performed on the raw field intensity data. For example, when the dielectric constant decreases as the temperature rises, the field intensity value needs to be reversely compensated. Next, the effect of humidity on electromagnetic wave propagation loss is superimposed. For example, in a high-humidity environment, the field intensity reading needs to be increased to offset the additional attenuation. Finally, combined with the real-time deformation state of the carbon fiber conductive cloth (such as the bending angle), the sensor position offset error caused by the deformation is compensated, and the final compensated field intensity data is output.

[0031] In one real-world case, within the complex electromagnetic environment of a spacecraft cabin, the detection unit detected a peak original field strength of 100V / m in a specific area, while the ambient temperature was 40°C and the humidity was 65%. The system applied positive compensation to the field strength value based on temperature parameters, superimposed humidity compensation, and combined it with cabin wall bending deformation data for additional compensation. The system ultimately outputs compensated field strength data for subsequent shielding control.

[0032] 102. Based on the compensation field strength data, a metal layer is deposited on the carbon fiber surface through a metal deposition process to form a metal mesh structure, and adjacent pore sizes of the metal mesh structure are gradient-differentiated to obtain porosity distribution parameters that match the surface deformation characteristics of the carbon fiber conductive cloth; In this step, the metal deposition process refers to a process of forming a metal conductive layer on the surface of the carbon fiber by chemical plating or vacuum coating technology.

[0033] Gradient difference generation refers to generating a sequence of gradually changing adjacent aperture sizes based on shielding requirements, and the difference rate is positively correlated with the field strength attenuation requirement.

[0034] Porosity distribution parameters are a set of parameters that describe the porosity variation patterns in different regions of the metal mesh.

[0035] In an embodiment of the present application, first, the direction of the field intensity gradient is identified based on the compensated field intensity data (for example, the field intensity gradually weakens along a certain axis), and the metal mesh is divided into sub-areas with high, medium, and low attenuation requirements. Secondly, the difference rate of adjacent aperture sizes is generated according to the attenuation requirement level. For example, the difference rate in the high attenuation area is higher. Then, the aperture difference rate of the outer area of ​​the bend is limited in combination with the maximum allowable elongation of the carbon fiber to avoid structural fracture caused by deformation. Finally, a gradient pore structure is formed on the metal layer through a laser etching process, and optical detection is used to verify whether the aperture size meets the design requirements.

[0036] Continuing with the previous example, the system identifies a high-field intensity area on the spacecraft bulkhead as requiring high attenuation, generating a sequence with a high variance in adjacent aperture sizes. The variance is limited based on the curvature of the bulkhead mounting surface. After laser etching, microscopy is used to verify that the aperture size tolerances meet process requirements.

[0037] 103. Based on the porosity distribution parameters, a metal mesh layer having a gradient pore size distribution is formed on the carbon fiber surface using a metal plating process, and the gradient pore size distribution is subjected to deformation adaptation processing based on the real-time acquired bending curvature data of the carbon fiber conductive cloth to generate a porosity distribution; In this step, deformation adaptation processing refers to dynamically adjusting the pore distribution according to real-time deformation data to maintain the stability of shielding effectiveness.

[0038] The metal plating process refers to the process of plating highly conductive materials on the surface of a gradient pore structure to optimize the current path.

[0039] In the embodiments of this application, first, a curvature sensor is used to monitor the bending direction and curvature radius of the carbon fiber conductive fabric in real time. Secondly, the pore size gradient direction is adjusted based on the bending direction, for example, by adjusting the original gradient direction to be orthogonal to the bending direction. Next, the magnitude of the increase in the pore size difference rate in the area outside the bend is calculated to generate a dynamically adjusted pore distribution. Finally, a conductive material is plated on the surface of the adjusted pore structure through a mask electroplating process to enhance conductivity and solidify the structure.

[0040] Continuing with the above example, the spacecraft cabin wall bends during the deployment process. The system adjusts the pore gradient direction based on the curvature data, increases the outer aperture difference rate, and forms a conductive network that adapts to the deformation through mask electroplating.

[0041] 104. Divide the metal mesh layer into regions associated with electromagnetic field strength based on the porosity distribution to obtain divided regions. Based on the divided regions, dynamically adjust the grounding resistance value of each divided region using a pulse width modulation signal to generate a resistance control parameter corresponding to the compensation field strength data. In this step, region division refers to dividing the metal mesh layer into multiple independent control regions according to the porosity distribution.

[0042] The pulse width modulation signal is a signal that controls the ground resistance value by adjusting the duty cycle of the square wave signal.

[0043] In the present embodiment, the metal mesh layer is first divided into high-, medium-, and low-density regions based on their porosity distribution. Next, a baseline ground resistance value is assigned to each region. Next, a pulse-width modulation signal is generated based on real-time compensation field strength data to dynamically adjust the resistance value of each region. For example, as field strength increases, the duty cycle is increased to reduce resistance. Finally, resistance adjustment commands are executed using a digital potentiometer to ensure that the impedance of each region matches the field strength distribution.

[0044] Continuing with the above example, in a certain dynamic field strength area on the spacecraft cabin wall, the system detects a transient increase in field strength and automatically adjusts the duty cycle of the pulse width modulation signal in the corresponding area to suppress electromagnetic leakage.

[0045] 105. Based on the resistance control parameter, a multi-level conductive dielectric layer is set between the metal mesh layer and the ground end, and the conductive dielectric layer and the metal mesh layer are physically connected through a flexible bonding process to obtain an electromagnetic shielding effectiveness parameter.

[0046] In this step, the multi-level conductive medium layer refers to a transition layer composed of different conductive materials, and the density decreases from the metal mesh to the ground end.

[0047] The flexible bonding process refers to a process that uses low-temperature pressing technology to achieve reliable connection between the dielectric layer and the metal mesh.

[0048] In the examples of this application, first, the dielectric layer density gradient is designed based on the resistance control parameters, for example, gradually transitioning from a high-density metal mesh to a low-density ground terminal. Secondly, the mixed conductive material is applied layer by layer through screen printing. Next, each layer is pressurized and cured at low temperature to form a flexible bonding interface. Finally, electrical testing is performed to verify the interlayer contact resistance and ensure that the shielding effectiveness meets the requirements.

[0049] Continuing with the above example, a multi-level dielectric layer is set between the spacecraft cabin shielding layer and the ground terminal, a flexible connection is formed through low-temperature pressing, and the contact resistance is verified to meet the requirements through testing.

[0050] In summary, steps 101 to 105 improve field strength measurement accuracy through environmental compensation, generate a gradient pore structure that dynamically adapts to deformation, and combine resistance control with dielectric layer optimization to achieve precise shielding in non-uniform electromagnetic fields. In the complex operating conditions of spacecraft, shielding fluctuations under bending deformation are significantly reduced, impedance matching efficiency is improved, and low-cost processes enable large-scale application, meeting the requirements of high-reliability scenarios.

[0051] In order to solve the problem of insufficient dynamic response of traditional electromagnetic shielding solutions under non-uniform field strength, in some embodiments, in step 102, based on the compensation field strength data, a metal layer is deposited on the carbon fiber surface through a metal deposition process to form a metal mesh structure, and a gradient difference is generated for adjacent pore sizes of the metal mesh structure to obtain porosity distribution parameters that match the surface deformation characteristics of the carbon fiber conductive cloth, including: 201. Generate a field intensity adjustment parameter corresponding to the surface of the carbon fiber conductive cloth based on the field intensity gradient direction and intensity data in the compensated field intensity data, wherein the field intensity adjustment parameter includes the field intensity attenuation requirement level of each area; In step 201, the field intensity adjustment parameter refers to a quantitative control parameter generated based on the compensated field intensity data, including the field intensity attenuation requirement level of each area (such as high, medium, and low), which is used to guide the gradient design of the metal mesh structure.

[0052] The field intensity gradient direction and intensity data refer to the core parameters in the compensation field intensity data that characterize the direction and amplitude of the electromagnetic field intensity change.

[0053] In an embodiment of the present application, first, the field strength gradient direction is extracted from the compensated field strength data, for example, it is identified that the field strength gradually decays along the positive direction of the X-axis; secondly, the surface of the carbon fiber conductive cloth is divided into areas with high, medium and low attenuation requirements according to the field strength attenuation amplitude; then, a difference rate weight coefficient is assigned to each area, for example, the high attenuation area has the highest weight, the medium attenuation area is second, and the low attenuation area is the lowest; finally, a field strength adjustment parameter including the area coordinate range and the weight coefficient is generated for subsequent steps to call.

[0054] 202. Divide the metal mesh structure into a plurality of continuous sub-regions according to the field intensity attenuation requirement level in the field intensity adjustment parameter, and generate an aperture difference sequence based on the aperture difference between adjacent sub-regions; In step 202 , the aperture difference sequence refers to a regular sequence of aperture size changes between adjacent sub-regions, for example, the aperture size increases by 5% from region A to region B.

[0055] The field intensity attenuation requirement level is the shielding intensity grading index for each area defined in the field intensity adjustment parameters.

[0056] In an embodiment of the present application, first, the metal mesh is divided into multiple continuous sub-regions along the direction of the field intensity gradient, for example, three sub-regions are divided along the positive direction of the X-axis; secondly, the aperture difference rate is defined for adjacent sub-regions according to the field intensity attenuation requirement level, for example, the high attenuation area has the largest difference rate, followed by the medium attenuation area; then, a difference sequence including the aperture size change rate is generated, for example, the first sub-region has the smallest aperture, and the subsequent apertures increase step by step; finally, the difference sequence is output to the deformation adaptation processing module.

[0057] 203. Based on the maximum allowable elongation in the surface deformation characteristics of the carbon fiber conductive cloth, adjust the size differences of adjacent apertures in the aperture difference sequence to generate a deformation-adaptive aperture sequence; In step 203, the deformation-adaptive pore size sequence refers to the pore size difference sequence adjusted in combination with the maximum allowable elongation of the carbon fiber, to ensure the stability of the pore distribution during the deformation process.

[0058] The maximum allowable elongation is the critical elongation ratio (e.g. 30%) at which the carbon fiber conductive cloth does not break or fail to conduct electricity during deformation.

[0059] In an embodiment of the present application, first, the maximum allowable stretching rate of the carbon fiber conductive cloth is obtained, such as the upper limit of the tensile deformation allowed by the material; secondly, the upper limit of the aperture difference rate of the outer area of ​​the bend is limited according to the stretching direction, for example, the aperture difference rate of the outer area of ​​the bend must be lower than a preset threshold; then, the original aperture difference sequence is constrained and adjusted, such as reducing the difference rate of the outer area; finally, the deformation adaptability of the adjusted sequence is verified by simulation, and a deformation-adaptive aperture sequence is output.

[0060] 204. According to the deformation-adaptive aperture sequence, a metal mesh structure with continuously varying apertures is formed layer by layer on the carbon fiber surface through a metal deposition process; In step 204 , the metal deposition process refers to a process of forming a metal conductive layer layer by layer on the surface of the carbon fiber by chemical plating or vacuum coating.

[0061] Continuous pore size change refers to the gradual change of the pore size in the metal mesh structure according to the deformation adaptation sequence rules.

[0062] In an embodiment of the present application, first, a laser etching path is designed according to a deformation-adaptive aperture sequence, for example, an aperture increment rule is set along the direction of the field intensity gradient; secondly, a uniform metal layer, such as a copper layer, is deposited on the surface of the carbon fiber; then, a laser etcher is used to process the aperture according to a preset path, for example, gradually increasing the aperture starting from the first sub-area; finally, a metal mesh structure with continuous aperture changes is formed.

[0063] 205. Verify the pore size of the metal mesh structure. When the deviation between the actual pore size and the deformation-adaptive pore size sequence exceeds a preset error range, repeat the adjustment step until the preset error range is met, and output the porosity distribution parameter.

[0064] In step 205 , the preset error range refers to the maximum allowable deviation between the actual aperture size and the design value (eg, ±3%).

[0065] The adjustment step refers to re-execution of the iterative optimization process from step 203 to step 204 when the verification fails.

[0066] In the embodiment of the present application, first, the apertures of different areas of the metal mesh are randomly sampled and measured using an optical microscope; second, the deviation between the actual aperture and the deformation adaptation sequence is calculated; then, if the deviation exceeds the preset error range, return to step 203 to adjust the upper limit of the difference rate or the etching parameters; finally, repeat the process until all aperture deviations meet the standards, and output the final porosity distribution parameters.

[0067] Here's a specific example: In the deployment of electromagnetic shielding on the spacecraft bulkhead, the detection unit first captures the high field strength data of a certain area, and compensates it in combination with the ambient temperature and humidity and the bending deformation of the bulkhead to generate compensated field strength data. Based on the compensation data, it is identified that the field strength attenuates along the positive direction of the X-axis, and the high, medium and low attenuation areas are divided to generate field strength adjustment parameters. The metal mesh is divided into three sub-areas along the X-axis, and the difference sequence is defined as a step-by-step increase in aperture. The outer aperture difference rate is limited according to the maximum allowable elongation of the bulkhead, and a deformation-adaptive aperture sequence is generated after adjusting the sequence. After the metal layer is formed by chemical copper plating, a gradient pore structure is formed by laser etching in sequence. The detection found that the aperture at a certain point slightly exceeded the preset error range. After the etching parameters were readjusted and retested to meet the standards, the porosity distribution parameters were finally output for shielding effectiveness optimization.

[0068] In summary, steps 201 to 205 achieve precise adaptation of the shielding structure in non-uniform electromagnetic field environments by dynamically generating a deformation-adaptive aperture sequence, combined with a gradient etching process and a closed-loop verification mechanism. In the spacecraft bulkhead bending deployment scenario, the shielding layer maintains a stable pore distribution during deformation, effectively avoiding shielding failure due to structural distortion. The collaborative design of metal deposition and laser etching processes significantly reduces the complexity of traditional solutions, while ensuring process stability through iterative verification, providing an innovative solution for high-reliability electromagnetic shielding.

[0069] In order to solve the problem of failure of traditional shielding structures under dynamic deformation scenarios, in some embodiments, in step 103, based on the porosity distribution parameters, a metal mesh layer with a gradient pore size distribution is formed on the carbon fiber surface using a metal plating process, and the gradient pore size distribution is subjected to deformation adaptation processing based on the real-time bending curvature data of the carbon fiber conductive cloth to generate a porosity distribution, including: 301.

[0071] In an embodiment of the present application, first, the pore gradient direction is extracted based on the porosity distribution parameters (for example, the porosity increases along the Y-axis); secondly, an initial pore size distribution map is generated according to the difference rate of adjacent pore sizes (such as a 5% increase in pore size per millimeter); then, the distribution map is converted into laser etching path data; finally, an initial pore size distribution template that matches the carbon fiber surface morphology (such as surface curvature) is output.

[0072] 302. Based on the curvature radius and curvature direction in the curvature data acquired in real time, dynamically adjust the aperture gradient direction in the initial aperture distribution template to generate a deformation-adaptive aperture distribution template, wherein the dynamic adjustment includes increasing the aperture difference rate of the outer area according to the curvature direction; In step 302, the deformation-adaptive pore size distribution template refers to a pore size distribution design template obtained by dynamically adjusting the initial template in combination with real-time bending curvature data.

[0073] The bending direction refers to the main direction in which the carbon fiber conductive cloth deforms (such as the positive direction of the X axis).

[0074] In an embodiment of the present application, first, the bending direction (for example, bending in the positive direction of the X-axis) and the curvature radius (for example, 3 meters) of the carbon fiber are obtained in real time through a curvature sensor; secondly, the outer area is determined according to the bending direction (the outer side of the bend is the X+ direction); then, the increase in the aperture difference rate of the outer area is calculated according to the curvature radius (for example, a curvature radius of 3 meters corresponds to an increase of 15%); finally, the aperture difference rate of the outer area in the initial template is adjusted to generate a deformation-adaptive aperture distribution template.

[0076] Continuous pore size variation refers to the gradual distribution of pore sizes in the metal mesh layer according to template rules.

[0077] In an embodiment of the present application, first, a deformation-adaptive aperture distribution template is input into a laser etching control system; second, the mask opening size is dynamically adjusted according to the aperture gradient direction and difference rate in the template (for example, the opening size increases by 0.2 mm for every 10% increase in aperture); then, metal (such as a copper layer) is deposited layer by layer on the carbon fiber surface through a chemical plating process; finally, a metal mesh layer with continuous aperture changes is formed.

[0078] 304. Perform a bending deformation test on the metal mesh layer. When the bending curvature exceeds a preset threshold, obtain deformation aperture verification data. Use the deformation aperture verification data to update the deformation adaptive aperture distribution template to generate a porosity distribution.

[0079] In step 304 , the bending deformation test refers to an experiment in which mechanical bending is applied to the metal mesh layer to verify the deformation adaptability.

[0080] Deformation aperture verification data refers to the deviation data between the measured aperture distribution and the design value after the bending test.

[0081] In an embodiment of the present application, first, a preset bending curvature (for example, a curvature radius of 2 meters) is applied to the metal mesh layer; secondly, the actual pore size distribution data after deformation is obtained through an optical measuring device; then, the deviation between the actual data and the deformation adaptation template is compared. If the deviation exceeds a preset threshold (such as 5%), the pore size difference rate in the middle and outer sides of the template is readjusted; finally, iterative optimization is performed until the deviation meets the standard, and the final porosity distribution is output.

[0082] Here's a specific example: During the deployment of the flexible shielding layer for a spacecraft's deployable antenna, an initial aperture distribution template was generated based on the antenna's surface curvature, with a gradient of increasing aperture along the deployment direction (Z-axis). During antenna deployment, negative Z-axis curvature (radius of curvature 4 meters) was detected. The aperture variation in the outer region was increased to 18%, generating a deformable template. A dynamic mask was used to control electroless copper plating, creating a metal mesh layer with a gradual aperture change from 50μm to 80μm along the Z-axis. After deployment, a 6% aperture deviation was measured at a certain point. The template variation was adjusted to 16%, and the layer was re-plated. Ultimately, the deviation was reduced to 2%, and the optimized porosity distribution was output.

[0083] In summary, steps 301 to 304 address the issue of aperture distribution instability in flexible shielding layers under deformation scenarios through the dynamic generation of a deformation-adaptive template and a closed-loop verification mechanism. During deployment of a spacecraft deployable antenna, the metal mesh layer significantly reduces aperture deviation under bending deformation, ensuring the stability of shielding effectiveness. Through dynamic mask control and iterative optimization, precise fabrication of gradient pore structures on complex curved surfaces is achieved, providing an innovative approach for high-reliability shielding in dynamic electromagnetic environments.

[0084] In order to solve the problem of pore instability of the flexible shielding layer under dynamic tensile deformation, in some embodiments, in step 203, based on the maximum allowable elongation in the surface deformation characteristics of the carbon fiber conductive cloth, the adjacent aperture size differences in the aperture difference sequence are adjusted to generate a deformation-adaptive aperture sequence, including: 401. Determine a deformation constraint parameter of adjacent aperture size differences in the aperture difference sequence based on the main stretching direction and the maximum allowable stretching rate in the surface deformation characteristics of the carbon fiber conductive cloth; In step 401, the deformation constraint parameter refers to an aperture size adjustment rule defined according to the maximum allowable elongation rate and main stretching direction of the carbon fiber conductive cloth, and is used to limit the aperture change range of the deformation sensitive area.

[0085] The main tensile direction refers to the direction in which the carbon fiber conductive cloth undergoes major tensile deformation during the deformation process, such as the material texture direction or the direction of mechanical load.

[0086] In an embodiment of the present application, first, the maximum allowable stretching rate of the carbon fiber conductive cloth is obtained through material tensile testing or parameter manual (for example, the allowable tensile deformation does not exceed 30%); secondly, the main stretching direction is determined according to the material structural characteristics or historical deformation data (for example, along the longitudinal and weft directions of the fiber arrangement); then, the upper limit of the aperture size change rate in the outer area of ​​the stretching direction is calculated (for example, the maximum allowable stretching rate corresponds to the outer aperture difference rate not exceeding 25%); finally, deformation constraint parameters including direction constraints and difference rate constraints are generated.

[0087] 402. Based on the upper limit of the aperture size change rate in the deformation constraint parameter, perform step-by-step restriction processing on the adjacent aperture size differences located outside the stretching direction in the aperture difference sequence to generate a preliminary adjusted aperture sequence; In step 402, the preliminary adjustment of the aperture sequence refers to the result of preliminary optimization of the original aperture difference sequence according to the deformation constraint parameters, with a focus on constraining the aperture difference in the outer area of ​​the stretching direction.

[0088] In an embodiment of the present application, first, the sub-region located outside the stretching direction in the aperture difference sequence (for example, the end region in the positive direction of the X-axis) is identified; secondly, according to the upper limit of the aperture size change rate in the deformation constraint parameter, the adjacent aperture difference rate of the outer region is restricted step by step (for example, the original difference rate of 20% is reduced to 18%); then, the original difference rate of the non-outer region is kept unchanged; finally, the aperture sequence after preliminary adjustment is output.

[0089] 403. Based on the coupling relationship between the bending curvature and the tensile deformation in the surface deformation characteristics of the carbon fiber conductive cloth, perform compensatory adjustment processing on the size differences of adjacent apertures in the non-tensile direction in the preliminary adjustment aperture sequence to generate a compensatory adjustment aperture sequence; In step 403, the compensation adjustment aperture sequence refers to a balance optimization sequence for the aperture difference in the non-stretching direction after considering the coupling effect of bending curvature and stretching deformation.

[0090] In an embodiment of the present application, first, the non-tensile deformation characteristics of the carbon fiber conductive cloth under the action of bending curvature (for example, compression deformation in the Y-axis direction) are analyzed; secondly, based on the coupling relationship between bending curvature and tensile deformation, the compensation coefficient of the aperture difference in the non-tensile direction is calculated (for example, the difference rate in the compression deformation area is reduced by five percent); then, compensatory adjustments are made to the adjacent aperture differences in the non-tensile direction in the preliminary adjusted aperture sequence (for example, the difference rate in the Y-axis direction is reduced from fifteen percent to ten percent); finally, the compensated aperture sequence is output.

[0091] 404. Import the compensation adjustment aperture sequence into a deformation simulation test device. When the simulated tensile deformation exceeds the maximum allowable stretching rate, obtain deformation connectivity verification data. Use the deformation connectivity verification data to iteratively optimize the compensation adjustment aperture sequence and output a deformation adaptive aperture sequence.

[0092] In step 404, the deformation connectivity verification data refers to the actual pore size distribution connectivity index obtained through deformation simulation testing, which is used to evaluate the deformation adaptability of the pore size sequence.

[0093] In an embodiment of the present application, first, the compensation adjustment aperture sequence is introduced into a multi-degree-of-freedom deformation simulation test device; second, a mechanical load exceeding the maximum allowable stretching rate (for example, a tensile deformation of thirty-five percent) is applied to the carbon fiber conductive cloth; then, the aperture connectivity data after deformation (for example, the change in the spacing between adjacent apertures) is obtained through optical measurement or electrical conductivity testing; finally, if the connectivity data does not meet the standard (for example, the spacing change exceeds a threshold), the process returns to step 402 to readjust the aperture difference rate until the deformation adaptation aperture sequence meets the requirements.

[0094] Here's a specific example: In the preparation of the flexible shielding layer for a spacecraft deployable antenna, a maximum allowable stretch rate of 30% was determined based on the antenna substrate parameters, with the primary stretch direction being the Z-axis deployment direction. Deformation constraint parameters were generated with an upper limit of 25% on the outer aperture difference rate. The Z-axis end region was identified, and the original 20% difference rate was adjusted to 18%, generating a preliminary adjustment sequence. The compressive deformation in the Y-axis during antenna deployment was analyzed, and the aperture difference rate in the non-stretched direction was reduced by 5%, generating a compensatory adjustment sequence. After simulating a 35% stretch deformation, it was detected that the aperture spacing in a certain area exceeded the standard. The difference rate was readjusted to 17%, re-measured to meet the standard, and finally a deformation-adaptive aperture sequence was output.

[0095] In summary, steps 401 to 404 achieve pore stability in the flexible shielding layer under extreme tensile deformation through the definition of deformation constraint parameters, gradient adjustment of the aperture difference sequence, and iterative optimization. In the case of a spacecraft deployable antenna, the shielding layer maintains a uniform pore size distribution even after excessive stretching, effectively preventing deformation-induced conductive network fracture. Combining compensatory adjustments with a closed-loop verification mechanism significantly improves the reliability of the shielding structure under complex deformation environments, providing an innovative solution for electromagnetic protection of dynamically deployable equipment.

[0096] In order to solve the problem of shielding structure mismatch in dynamic deformation scenarios, in some embodiments, in step 302, the aperture gradient direction in the initial aperture distribution template is dynamically adjusted based on the curvature radius and curvature direction in the curvature curvature data acquired in real time to generate a deformation-adaptive aperture distribution template, including: 501.

[0098] In an embodiment of the present application, first, the bending direction (for example, the positive direction of the X-axis) is extracted from the bending curvature data; secondly, the aperture gradient direction (for example, the Y-axis direction) in the initial aperture distribution template is parsed; then, the angle between the two is calculated (for example, a 90° orthogonal relationship); finally, the relative position relationship is determined to be "orthogonal distribution" or "same-direction distribution", providing a basis for subsequent area marking.

[0099] 502. Mark the target adjustment area located outside the bending direction in the initial pore size distribution template according to the outer area definition rule in the relative position relationship; In step 502 , the outer region definition rule refers to determining the criteria for determining the tensile stress concentration region (ie, the outer region) during the deformation process based on the relative positional relationship between the bending direction and the aperture gradient direction.

[0100] The target adjustment area refers to the deformation-sensitive area where the aperture difference rate needs to be adjusted first, and is usually located on the outside of the bending direction.

[0101] In an embodiment of the present application, first, based on the relative position relationship obtained in step 501 (for example, orthogonal distribution), the outer area in the bending direction (such as the 5mm range at the end of the positive direction of the X-axis) is determined; secondly, the area is marked as the target adjustment area in the initial aperture distribution template; finally, target area parameters including area coordinates and adjustment priority are generated.

[0102] 503. Calculate the improvement range of the difference rate of adjacent apertures in the target adjustment area by using the preset mapping relationship between the curvature radius and the aperture difference rate, and generate a difference rate adjustment parameter; In step 503, the preset mapping relationship refers to a nonlinear correspondence rule between the curvature radius and the aperture difference rate. For example, the smaller the curvature radius, the greater the improvement of the difference rate.

[0103] The difference rate adjustment parameter refers to the optimized adjustment amount of the difference rate of adjacent aperture sizes in the target adjustment area.

[0104] In an embodiment of the present application, first, the preset mapping relationship is queried according to the bending curvature radius of step 501 (for example, 3 meters) to determine the improvement in the difference rate (for example, a curvature radius of 3 meters corresponds to an improvement of 15%); secondly, the adjusted difference rate is calculated (for example, 20% + 15% = 35%) based on the original difference rate of the target adjustment area (for example, 20%); finally, a parameter table containing the difference rate adjustment amount of each sub-area is generated.

[0105] 504 : performing a step-by-step increasing process on the adjacent aperture sizes of the target adjustment area according to the difference rate adjustment parameter, and performing a balance compensation process on the adjacent aperture sizes of the non-target adjustment area, to generate a deformation-adaptive aperture distribution template.

[0106] In step 504, the step-by-step increasing process refers to the operation of gradually increasing the difference in the sizes of adjacent apertures in the target area according to the difference rate adjustment parameter.

[0107] Balance compensation processing refers to the reverse adjustment of the aperture difference in the non-target adjustment area to maintain the balance of the overall shielding effectiveness.

[0108] In an embodiment of the present application, first, the adjacent aperture sizes of the target adjustment area are adjusted step by step according to the difference rate adjustment parameter (for example, from 50μm→55μm→60μm); secondly, the aperture difference rate of the non-target area (such as the inner side of the bend) is simultaneously reduced (for example, from 15% to 10%); then, the uniformity of the aperture distribution of the adjusted template is verified; finally, the deformation-adaptive aperture distribution template is output.

[0109] Here's a specific example: During the shielding preparation for a spacecraft deployable antenna, bending in the positive X-axis direction (radius of curvature 4 meters) was detected during antenna deployment. The initial aperture distribution template had a gradient oriented along the Y-axis, establishing an orthogonal relative positional relationship. Based on the orthogonal relationship, a 5mm area at the end of the positive X-axis was marked as the target adjustment area. Based on a mapping query with a 4-meter radius of curvature, the discrepancy rate increased by 12%, adjusting the target area's discrepancy rate from 18% to 30%. The aperture in the target area was increased in steps of 30% (50μm → 65μm → 84.5μm), while the discrepancy rate in the inner area was reduced from 15% to 10%, generating a deformable adaptive template. After the antenna was deployed, the measured shielding effectiveness fluctuation was less than 2dB, verifying the template's effectiveness.

[0110] In summary, steps 501 to 504 achieve adaptive matching of the flexible shielding layer under dynamic deformation by dynamically identifying the spatial relationship between the bending direction and the aperture gradient, accurately marking deformation-sensitive areas, and optimizing the difference ratio. In the case of a deployable spacecraft antenna, the adjusted aperture distribution template significantly reduces shielding effectiveness fluctuations caused by bending deformation, while maintaining the electromagnetic uniformity of the overall structure through a balanced compensation mechanism. Combined with curvature mapping and closed-loop verification, this method provides an innovative solution for high-reliability shielding design in complex deformation environments.

[0111] In order to solve the problem of shielding effectiveness distribution mismatch under non-uniform field strength, in some embodiments, in step 104, the metal mesh layer is divided into regions associated with the electromagnetic field strength based on the porosity distribution to obtain divided regions. Based on the divided regions, a pulse width modulation signal is used to dynamically adjust the ground resistance value of each divided region to generate a resistance control parameter corresponding to the compensation field strength data, including: 601. Based on the pore density gradient direction and the density change rate of adjacent regions in the porosity distribution, perform field intensity gradient direction identification processing on the metal mesh layer to generate field intensity gradient direction data; In step 601, the pore density gradient direction refers to the trend of the porosity in the metal mesh layer increasing or decreasing along a specific direction (such as the X-axis), reflecting the distribution pattern of the electromagnetic wave attenuation path.

[0112] Field intensity gradient direction data refers to the dominant direction of electromagnetic field intensity change identified based on porosity distribution, which is used to guide regional division.

[0113] In the embodiment of the present application, first, the porosity distribution of the metal mesh layer is analyzed to extract the gradient characteristics of the pore density decreasing along the Y-axis direction; second, based on the density change rate of the adjacent areas (such as a density decrease of 5% per millimeter), the main direction of the field intensity attenuation is determined to be the negative direction of the Y-axis; finally, field intensity gradient direction data including the gradient direction and change rate are generated.

[0114] 602.

[0115] Field intensity attenuation priority refers to the control level (such as high, medium, and low) divided according to the field intensity attenuation requirements of the sub-area.

[0116] In the embodiment of the present application, first, the directional consistency threshold is set to 15°, and the metal mesh layer is scanned along the negative direction of the Y-axis; secondly, the continuous areas with directional deviations less than the threshold are merged into sub-areas; then, the attenuation priority is assigned according to the sub-area field strength peak value (the higher the peak value, the higher the priority); finally, the area division parameters including the sub-area boundaries and priorities are generated.

[0117] 603. Determine a ground resistance reference value for each sub-area based on the field strength attenuation priority in the area division parameter, and generate a resistance difference sequence using differences in the ground resistance reference values ​​between adjacent sub-areas. In step 603 , the ground resistance reference value refers to the initial resistance value of each sub-area when there is no dynamic adjustment, and is negatively correlated with the field intensity attenuation priority.

[0118] The resistance difference sequence refers to the gradual change rule of the resistance values ​​of adjacent sub-regions, which is used to achieve impedance gradient matching.

[0119] In an embodiment of the present application, first, a low reference resistance value (such as 50Ω) is assigned to a high-priority sub-region, 100Ω to a medium priority, and 150Ω to a low priority; second, an adjacent resistance difference sequence is generated according to the arrangement order of the sub-regions (such as 50Ω→75Ω→100Ω→125Ω→150Ω); finally, a resistance difference sequence including a difference rate and a transition rule is output.

[0120] 604. Generate a dynamic adjustment parameter corresponding to the duty cycle of the pulse width modulation signal according to the resistance value change gradient in the resistance difference sequence; In step 604 , the resistance value variation gradient refers to the difference in resistance values ​​between adjacent sub-regions in the resistance difference sequence (eg, 25Ω / region).

[0121] The duty cycle of the pulse width modulation signal refers to the electrical parameter that controls the ground resistance value by adjusting the high level time ratio of the square wave signal.

[0122] In an embodiment of the present application, first, the target resistance change gradient of each sub-region is calculated based on the resistance difference sequence (for example, each region needs to be reduced by 25Ω); second, a corresponding relationship between the resistance change gradient and the duty cycle is established (for example, every 25Ω change corresponds to a 10% duty cycle adjustment); finally, a dynamic adjustment parameter containing the duty cycle adjustment amount of each sub-region is generated.

[0123] 605. Based on the dynamic adjustment parameter, the ground resistance reference value of each sub-area is adjusted step by step through a pulse width modulation signal to generate a resistance control parameter that matches the field intensity gradient distribution in the compensation field intensity data.

[0124] In step 605, the step-by-step adjustment process refers to adjusting the ground resistance value of each sub-region in the order of the dynamic adjustment parameters to ensure impedance matching continuity.

[0125] In an embodiment of the present application, first, the dynamic adjustment parameters are input into the digital potentiometer control system; second, the duty cycle is adjusted in sequence from high to low according to the sub-area priority (such as increasing the duty cycle of the high-priority area to 70%); then, the resistance value change is monitored in real time until the target gradient is reached; finally, the resistance control parameters that match the field intensity gradient distribution are output.

[0126] Here's a specific example: In the deployment of the electromagnetic shielding layer on a spacecraft bulkhead, the porosity distribution of the metal mesh was analyzed, and the direction of the field intensity gradient was identified as the negative Y-axis, generating gradient direction data. Five consecutive sub-regions were divided along the Y-axis, assigned high, medium, and low attenuation priorities, and generating regional division parameters. A baseline resistance of 50Ω was set for the high-priority region, generating a resistance variation sequence (50Ω→75Ω→100Ω→125Ω→150Ω). A dynamic parameter was established, with a 10% duty cycle adjustment corresponding to every 25Ω resistance change. The duty cycle in the high-priority region was adjusted to 70%, gradually decreasing to 30% in the low-priority region, generating resistance control parameters. Bulkhead testing showed that the shielding effectiveness distribution closely matched the field intensity gradient, and the leakage signal was reduced to an acceptable level.

[0127] In summary, steps 601 to 605 achieve precise impedance matching in non-uniform electromagnetic fields through field intensity gradient identification, regional priority division, and dynamic resistance adjustment. In the spacecraft bulkhead scenario, the resistance control parameters are spatially mapped to the field intensity distribution, significantly improving the uniformity of shielding effectiveness. The closed-loop adjustment mechanism ensures rapid response to dynamic field intensity changes, while the gradient transition design avoids the impedance abrupt change problem of traditional solutions, providing a highly adaptable solution for complex electromagnetic environments.

[0128] In order to solve the problem of field strength measurement distortion caused by environmental interference, in some embodiments, in step 101, spatial field strength data in a non-uniform electromagnetic field environment is obtained based on a detection unit arranged on the surface of the carbon fiber conductive cloth, and the spatial field strength data is subjected to physical field correction in combination with the synchronously obtained ambient temperature and humidity parameters to obtain compensated field strength data, including: 701.

[0130] In an embodiment of the present application, first, the field intensity sensing element scans the target area at a fixed sampling frequency to generate a spatial field intensity raw data matrix; second, the environmental sensing unit collects temperature and humidity parameters at the same timestamp; finally, the two types of data are aligned in time to establish an original data set with environmental labels.

[0131] 702. Perform temperature compensation processing on the dielectric constant deviation in the spatial field strength raw data based on the temperature parameter to generate temperature-corrected field strength data; In step 702, the dielectric constant deviation refers to the field strength measurement error caused by the change in dielectric properties of the carbon fiber substrate due to temperature change.

[0132] Temperature compensation processing refers to the reverse correction of the original field strength data according to the temperature parameter to eliminate the influence of the dielectric constant temperature drift.

[0133] In an embodiment of the present application, first, a temperature-dielectric constant correspondence model is established (for example, an increase in temperature causes a decrease in dielectric constant); second, a dielectric constant correction coefficient is calculated based on the real-time temperature parameter; then, the original field strength data is linearly scaled (for example, for every 10°C increase in temperature, the field strength reading increases by a set value); finally, the temperature-corrected field strength data is output.

[0134] 703. Perform humidity compensation processing on the electromagnetic wave propagation loss in the temperature-corrected field intensity data based on the humidity parameter to generate temperature-humidity jointly corrected field intensity data. In step 703, the electromagnetic wave propagation loss refers to the additional attenuation caused by the absorption effect of water molecules on the electromagnetic waves in a high humidity environment.

[0135] Humidity compensation is the process of offsetting the propagation loss caused by humidity by improving the field strength reading.

[0136] In an embodiment of the present application, first, a preset humidity-loss mapping table is queried based on the humidity parameter (for example, for every 20% RH increase in humidity, the loss increases by a set value); secondly, a compensation amount is superimposed on the temperature-corrected field strength data; then, the frequency domain consistency of the compensated data is verified; finally, the temperature and humidity jointly corrected field strength data is output.

[0137] 704. Perform deformation additional error compensation processing on the temperature and humidity combined corrected field strength data according to the surface deformation state of the carbon fiber conductive cloth, and output compensated field strength data.

[0138] In step 704, the deformation additional error refers to the positional offset of the detection unit caused by the bending of the carbon fiber conductive cloth, which in turn causes spatial distortion of the field intensity measurement.

[0139] The deformation state refers to the real-time bending angle and direction data of the carbon fiber surface obtained by curvature sensors or strain gauges.

[0140] In an embodiment of the present application, first, the real-time bending direction (for example, the positive direction of the X-axis) and the curvature radius (for example, 3 meters) of the carbon fiber conductive cloth are obtained through a curvature sensor; secondly, the position offset of the detection unit is calculated according to the bending geometry model; then, the spatial coordinate correction is performed on the temperature and humidity joint correction data; finally, the compensated field strength data is output.

[0141] Here's a specific example: In a spacecraft cabin electromagnetic environment monitoring scenario, a field strength sensor on the carbon fiber conductive fabric of the cabin wall detected a peak original field strength of 100 V / m in a certain area. Simultaneously, the environmental sensor measured a temperature of 45°C and a humidity of 70% RH. Based on the temperature-dielectric constant model, a positive compensation was applied to the 100 V / m field strength value, generating a temperature correction value of 115 V / m. Humidity compensation was then applied according to the humidity compensation rules, raising the field strength to 125 V / m. The cabin wall was detected to be curved in the X-axis (radius of curvature 2 meters) due to equipment installation. After correcting for positional offset, the final compensated field strength was output at 130 V / m.

[0142] In summary, steps 701 to 704 significantly improve the accuracy of non-uniform electromagnetic field measurements through the simultaneous acquisition of multi-source data and dynamic compensation of environmental parameters. Under the complex operating conditions within the spacecraft cabin, the compensated field strength data effectively eliminates interference from temperature, humidity, and deformation, providing reliable input for subsequent shielding structure optimization.
