[0002] In the application of modern electromagnetic equipment, the performance of electromagnetic generators has an important impact on efficiency and energy management. As a common source of electromagnetic waves, electromagnetic generators have been widely used in many fields such as wireless communications, sensors, radars, etc. However, traditional electromagnetic generators usually rely on experience or manual adjustment in parameter configuration, lacking systematic analysis methods and intelligent configuration methods. The traditional configuration method usually determines the parameters such as the operating frequency, power and layout position of the electromagnetic generator based on the set empirical values, but the setting of these parameters fails to fully consider the impact of different layout positions on the propagation of electromagnetic waves and the energy consumption differences at each position. This subjective configuration method may lead to unnecessary energy loss of the electromagnetic generator in certain layout positions, resulting in low system efficiency.

[0003] In the prior art, existing optimization methods usually rely on a single or empirical adjustment method, which cannot fully and accurately consider the energy consumption impact brought by different layout positions. For example, in different spatial layout positions, the propagation characteristics of electromagnetic waves may vary due to obstacles, environmental factors or design differences of the equipment itself. Therefore, the energy efficiency and effect of the same electromagnetic wave generator in different positions will vary significantly. However, current technology has failed to effectively optimize the layout position intelligently, resulting in the inability to achieve the best balance between energy efficiency and performance.

[0004] In summary, there is a technical problem in the prior art that the parameters of the traditional electromagnetic generator do not take into account the energy consumption parameters of different layout positions, which may cause unnecessary energy loss, further affecting the overall energy efficiency and performance, making it difficult to achieve intelligent configuration of the parameters of the electromagnetic generator.

[0014] This application provides a method and system for testing the electromagnetic shielding performance of a shielding cover for a smart wearable terminal, solving the technical problem in the prior art that the parameters of the traditional electromagnetic generator do not take into account the energy consumption parameters of different layout positions, which may cause unnecessary energy loss, further affecting the overall energy efficiency and performance, and making it difficult to realize the intelligent configuration of the parameters of the electromagnetic generator.

[0015] Below, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0016] For example, please refer to the attached Figure 1 The present application provides an electromagnetic shielding performance testing method for a smart wearable terminal shielding cover, which is applied to an electromagnetic shielding performance testing system for a smart wearable terminal shielding cover, and specifically includes the following steps: Step 1: Obtain an electromagnetic shielding performance test case, wherein the electromagnetic shielding performance test case includes testing the magnetic field strength.

[0017] Specifically, when conducting electromagnetic shielding performance tests, test cases are obtained to evaluate the effectiveness of electromagnetic shielding. Electromagnetic shielding performance test cases include testing magnetic field strength. Test magnetic field strength refers to the number of magnetic lines of force passing through a unit area, which is used to describe the strength of the electromagnetic field. By measuring the magnetic field strength, it is possible to determine whether the electromagnetic shielding material effectively blocks the influence of the external magnetic field. By obtaining the test magnetic field strength, the performance of different shielding materials under different test conditions can be quantitatively evaluated, and the best electromagnetic shielding solution can be selected. By comparing the position changes of different materials or layouts, the shielding effect can be further optimized, energy loss can be reduced, and stability and efficiency can be improved.

[0018] Step 2: According to the test magnetic field strength and the initial magnetic field strength of the shielded area, the electromagnetic wave generator is optimized for energy saving layout in the non-shielded area to obtain the layout position of the electromagnetic wave generator, wherein the layout position of the electromagnetic wave generator includes the electromagnetic wave generation frequency and the electromagnetic wave generation power.

[0019] Specifically, the magnetic field state of the current area is obtained by measuring the test magnetic field strength and the initial magnetic field strength of the shielded area, and then the energy-saving layout of the electromagnetic wave generator is optimized in the non-shielded area, that is, the layout position of the electromagnetic wave generator is adjusted to find the most energy-saving configuration and obtain the layout position of the electromagnetic wave generator. The configuration includes the frequency and power of the electromagnetic wave, which are used to affect the energy efficiency and performance of the electromagnetic wave generator.

[0020] Step three: deploy the electromagnetic wave generator at the electromagnetic wave generator layout position, and emit electromagnetic waves according to the electromagnetic wave generation frequency and the electromagnetic wave generation power, and collect the shielding area monitoring magnetic field strength through the shielding area magnetic field sensor, wherein there is no interfering shielding object between the non-shielded area and the shielding area except the shielding cover of the smart wearable terminal.

[0021] Specifically, after optimizing and determining the layout position of the electromagnetic wave generator, the electromagnetic wave generator is deployed at the layout position of the electromagnetic wave generator, and the electromagnetic wave is emitted through the previously configured electromagnetic wave generation frequency and electromagnetic wave generation power, and the magnetic field strength is monitored in real time by using the magnetic field sensor in the shielding area to obtain the monitored magnetic field strength of the shielding area, so as to further analyze the impact of the electromagnetic wave on the environment in the area. Among them, there is no interference shielding object between the non-shielded area and the shielding area except the shielding cover of the smart wearable terminal, that is, except for the shielding cover of the smart wearable terminal, there is no additional interference shielding object in other areas.

[0022] Step 4: When the ratio of the monitored magnetic field strength in the shielding area to the tested magnetic field strength is greater than or equal to the qualified ratio, an electromagnetic shielding abnormality mark is performed on the shielding cover of the smart wearable terminal.

[0023] Specifically, when the ratio of the monitored magnetic field strength to the tested magnetic field strength in the shielding area is greater than or equal to the qualified ratio, it indicates that the shielding cover may be insufficient and fails to effectively shield the electromagnetic waves, which may cause electromagnetic wave leakage or interference problems, and then the shielding cover of the smart wearable terminal is marked as electromagnetic shielding abnormality. The qualified ratio is obtained by customized settings by technical personnel in this field based on actual conditions.

[0024] The electromagnetic shielding performance testing method for the smart wearable terminal shielding cover is applied to an electromagnetic shielding performance testing system for the smart wearable terminal shielding cover, which can achieve the technical goal of intelligent optimization configuration of the layout position and parameters of the electromagnetic generator, and achieve the technical effect of improving energy efficiency, reducing energy waste, and enhancing the overall performance of the electromagnetic equipment.

[0025] Furthermore, the present application also includes: uniformly laying out positions in the non-shielded area at a preset distance to obtain a first layout position until the Nth layout position; based on the first layout position, in combination with the test magnetic field strength and the initial magnetic field strength of the shielded area, configuring the electromagnetic wave generation frequency and the electromagnetic wave generation power to obtain the electromagnetic wave generation frequency of the first layout position and the electromagnetic wave generation power of the first layout position; until based on the Nth layout position, in combination with the test magnetic field strength and the initial magnetic field strength of the shielded area, configuring the electromagnetic wave generation frequency and the electromagnetic wave generation power to obtain the electromagnetic wave generation frequency of the Nth layout position and the electromagnetic wave generation power of the Nth layout position; according to the electromagnetic wave generation frequency of the first layout position and the electromagnetic wave generation power of the first layout position, until the electromagnetic wave generation frequency of the Nth layout position and the electromagnetic wave generation power of the Nth layout position are optimized for energy-saving layout positions to obtain the layout position of the electromagnetic wave generator, wherein the layout position of the electromagnetic wave generator includes the electromagnetic wave generation frequency and the electromagnetic wave generation power.

[0026] Specifically, in an area without electromagnetic shielding, the layout is carried out according to a pre-set distance, that is, multiple locations are selected in the area without electromagnetic shielding, and the spacing between the locations is kept equal. The preset distance refers to the interval determined before the layout is carried out to ensure the consistency and comparability of the test. For example, the preset distance is one meter.

[0027] Starting from the first layout point, until the Nth layout point, the first layout position is obtained until the Nth layout position, and a complete layout position sequence is obtained to ensure that all positions are evenly distributed in space. N is an integer greater than or equal to 1, and N represents the total number of layout points. Each position is numbered for subsequent analysis and comparison.

[0028] At the first layout position, the electromagnetic wave generation frequency and the electromagnetic wave generation power are determined in combination with the actually measured test magnetic field strength and the initial magnetic field strength of the shielding area in the absence of shielding, that is, the appropriate frequency and power are selected according to the magnetic field strength data to ensure that the expected electromagnetic wave effect is generated at the layout position, and then the electromagnetic wave generation frequency at the first layout position and the electromagnetic wave generation power at the first layout position are obtained, and the specific electromagnetic wave generation frequency and power values ​​required to be used at the layout position are obtained.

[0029] According to the method of obtaining the first layout position electromagnetic wave generation frequency and the first layout position electromagnetic wave generation power of the first layout position, at the Nth layout position, combined with the actually measured test magnetic field strength and the initial magnetic field strength of the shielding area without shielding, select the appropriate frequency and power to ensure the expected electromagnetic wave effect at the layout position, and obtain the Nth layout position electromagnetic wave generation frequency and the Nth layout position electromagnetic wave generation power. The electromagnetic wave generation frequency and power configuration of each layout position will be adjusted and optimized based on the test magnetic field strength and the initial magnetic field strength of the shielding area at the position, so each layout point will have a corresponding electromagnetic wave frequency and power value, thereby ensuring uniform and scientific electromagnetic wave testing in the entire area.

[0030] The energy-saving layout position is optimized according to the electromagnetic wave generation frequency and the electromagnetic wave generation power of the first layout position, until the electromagnetic wave generation frequency and the electromagnetic wave generation power of the Nth layout position, that is, from the first layout position to the Nth layout position, the energy-saving optimization is performed according to the electromagnetic wave generation frequency and power setting of each layout position in turn. The electromagnetic wave generation frequency and the electromagnetic wave generation power directly affect the energy efficiency of the electromagnetic wave generator. The electromagnetic wave generation frequency determines the oscillation speed of the electromagnetic wave, and the electromagnetic wave generation power determines the energy output of the electromagnetic wave. By comparing the configurations of different layout positions, the optimization process can help select the most energy-saving electromagnetic wave frequency and power combination at each position, thereby reducing energy consumption.

[0031] After optimizing the electromagnetic wave generator layout, the optimal electromagnetic wave generator layout was determined. Among them, the electromagnetic wave generator layout position includes the electromagnetic wave generation frequency and electromagnetic wave generation power. The electromagnetic wave generator layout position is configured with the most suitable electromagnetic wave generation frequency and power to ensure that the electromagnetic wave generator can meet the functional requirements while being the most energy-efficient. The electromagnetic wave generation frequency and power are the key factors that determine the electromagnetic wave performance and energy consumption. Therefore, the best energy efficiency performance can be achieved by reasonably configuring the parameters.

[0032] Furthermore, the present application also includes: according to the electromagnetic wave generator, obtaining the occurrence frequency constraint interval and the occurrence power constraint interval for random assignment, and obtaining the occurrence frequency assignment result and the occurrence power assignment result; obtaining the distance parameter between the first layout position and the shielding area; predicting the magnetic field strength according to the initial magnetic field strength of the shielding area, the distance parameter, the occurrence frequency assignment result and the occurrence power assignment result, and obtaining the predicted magnetic field strength of the shielding area; when the magnetic field strength deviation between the predicted magnetic field strength of the shielding area and the test magnetic field strength is less than or equal to the magnetic field strength deviation threshold, setting the occurrence frequency assignment result to the first layout position electromagnetic wave occurrence frequency, and setting the occurrence power assignment result to the first layout position electromagnetic wave occurrence power.

[0033] Specifically, the test is performed by using an electromagnetic wave generator. An electromagnetic wave generator is a tool used to generate electromagnetic wave signals, which can generate electromagnetic waves of specific frequency and power according to set requirements. The electromagnetic wave generator provides a standard electromagnetic field source for the test to ensure consistency and comparability of the test results.

[0034] According to the setting range of the electromagnetic wave generator, the frequency and power values ​​are selected to obtain the occurrence frequency constraint interval and the occurrence power constraint area. The occurrence frequency constraint interval refers to the frequency range that the electromagnetic wave generator can output, and the occurrence power constraint interval refers to the output power range of the electromagnetic wave generator. Randomly select the frequency and power values ​​in the occurrence frequency constraint interval and the occurrence power constraint area to obtain the occurrence frequency assignment results and the occurrence power assignment results, which are used to test the performance of shielding materials under different conditions.

[0035] Since different spatial distances between the first layout position and the area covered by the electromagnetic shielding material may lead to different electromagnetic shielding effects, the spatial distance between the first layout position and the area covered by the electromagnetic shielding material is obtained as a distance parameter.

[0036] The initial magnetic field strength, distance parameters, occurrence frequency assignment results and occurrence power assignment results of the shielding area are input into the prediction model built based on historical information to predict the magnetic field strength, obtain the predicted magnetic field strength of the shielding area, and then predict the actual magnetic field strength of the shielding area in order to evaluate the shielding effect.

[0037] When the magnetic field strength deviation between the predicted magnetic field strength of the shielding area and the tested magnetic field strength is less than or equal to the magnetic field strength deviation threshold, it means that the predicted magnetic field strength of the shielding area is compared with the actually measured magnetic field strength, and the gap (i.e., deviation) is small enough. Then, the prediction model is considered to be accurate, that is, the predicted magnetic field strength of the shielding area is accurate, and further operations can be performed.

[0038] The frequency assignment result is set as the electromagnetic wave frequency at the first layout position, and the power assignment result is set as the electromagnetic wave power at the first layout position, that is, the previously randomly assigned electromagnetic wave frequency and power are applied to the actual layout position. The first layout position refers to a specific position within the shielding area, and the electromagnetic wave frequency and power are the parameters used to generate electromagnetic waves at that position. By setting the electromagnetic wave frequency at the first layout position and the electromagnetic wave power at the first layout position, the shielding effect can be effectively evaluated.

[0039] Furthermore, the present application also includes: configuring the target area before adjustment magnetic field strength record information, distance parameter record information, occurrence frequency record information, occurrence power record information and the target area after adjustment magnetic field strength record information; using the target area after adjustment magnetic field strength record information as supervision, and using the target area before adjustment magnetic field strength record information, the distance parameter record information, the occurrence frequency record information, the occurrence power record information as input, to train an initial magnetic field strength prediction channel; extracting a set of magnetic field strength output deviation vectors whose output accuracy of the initial magnetic field strength prediction channel is less than or equal to an output accuracy threshold; when the number of the magnetic field strength output deviation vector sets is greater than or equal to a number threshold, The magnetic field strength output deviation vector set is used as supervision, and the magnetic field strength record information of the target area before adjustment, the distance parameter record information, the occurrence frequency record information, and the occurrence power record information are used as input to train the first residual fitting channel; until the number of magnetic field strength output deviation vector sets of the Mth residual fitting channel is less than the quantity threshold, the outputs of the initial magnetic field strength prediction channel, the first residual fitting channel until the Mth residual fitting channel are added and fused to obtain a magnetic field strength prediction model, and the magnetic field strength is predicted according to the initial magnetic field strength of the shielded area, the distance parameter, the occurrence frequency assignment result, and the occurrence power assignment result to obtain the predicted magnetic field strength of the shielded area.

[0040] Specifically, the target area magnetic field strength record information before adjustment refers to the magnetic field strength before the target area is adjusted, the target area distance parameter record information before adjustment refers to the distance parameter of the layout position before the target area is adjusted, the target area occurrence frequency record information before adjustment refers to the occurrence frequency and power used before the target area is adjusted, and the target area magnetic field strength record information after adjustment refers to the magnetic field strength after the target area is adjusted. Configuring the target area magnetic field strength record information before adjustment, distance parameter record information, occurrence frequency record information, occurrence power record information, and target area magnetic field strength record information after adjustment refers to the information recorded during the experiment or test process, which is then used to measure the performance of the shielding material under different experimental conditions and provide a basis for subsequent analysis.

[0041] The target area is adjusted and recorded with magnetic field strength information as supervision, and the target area is adjusted and recorded with magnetic field strength information, distance parameter information, occurrence frequency information, and occurrence power information as input to train the initial magnetic field strength prediction channel. The initial magnetic field strength prediction channel is trained by using the input data, and when the output of the initial magnetic field strength prediction channel tends to be stable, the initial magnetic field strength prediction channel is verified by the supervised data, and the verification accuracy is output. When the verification accuracy of the initial magnetic field strength prediction channel is greater than the output accuracy threshold, the training of the initial magnetic field strength prediction channel is completed. The output accuracy threshold is obtained by a technician in this field according to the actual situation, such as the preset output accuracy threshold is 95%.

[0042] A set of magnetic field strength output deviation vectors whose output accuracy of the initial magnetic field strength prediction channel is less than or equal to the output accuracy threshold is extracted, indicating that inaccurate magnetic field strength deviation vectors are extracted after supervised data verification, which are used to optimize the prediction deficiencies of the initial magnetic field strength prediction channel and further optimize the initial magnetic field strength prediction channel.

[0043] When the number of the magnetic field intensity output deviation vector set is greater than or equal to the quantity threshold, it means that the number of deviation vectors is large, and the error in the previous prediction needs to be compensated to further improve the prediction accuracy. Therefore, the magnetic field intensity output deviation vector set is used as supervision, and the magnetic field intensity recording information, distance parameter recording information, occurrence frequency recording information, and occurrence power recording information before the target area is adjusted are used as input to train the first residual fitting channel. Among them, the first residual fitting channel is trained by the input data, and when the output of the first residual fitting channel tends to be stable, the first residual fitting channel is verified by the supervised data, and when the verification accuracy of the verification output is greater than the output accuracy threshold, the training of the first residual fitting channel is completed.

[0044] According to the training method of the first residual fitting channel, the second residual fitting channel is trained in sequence until the Mth residual fitting channel. M is an integer greater than or equal to 1. M represents the number of residual fitting channels. The M magnetic field intensity output deviation vector sets of the first residual fitting channel until the Mth residual fitting channel obtained by supervision are obtained. When the number of the M magnetic field intensity output deviation vector sets is less than the quantity threshold, the initial magnetic field intensity prediction channel, the first residual fitting channel until the Mth residual fitting channel are output summed and fused to obtain a magnetic field intensity prediction model. Among them, output summation and fusion refers to combining the prediction results or output values ​​of multiple models, and integrating them into a final output by summing them. By combining the results of multiple prediction channels or models, the possible deficiencies of a single model are compensated, thereby improving the accuracy and reliability of the final prediction results.

[0045] The initial magnetic field strength, distance parameters, occurrence frequency assignment results and occurrence power assignment results of the shielding area are input into the magnetic field strength prediction model to predict the magnetic field strength and obtain the predicted magnetic field strength of the shielding area, which provides data support for optimizing the shielding area design and verifying the electromagnetic shielding effect.

[0046] Through the training of multiple prediction channels and residual fitting, the accuracy of the model is gradually optimized. By fusing the outputs of different channels, a more accurate magnetic field strength prediction model is obtained. It can effectively predict the magnetic field strength according to actual conditions, thus providing a basis for electromagnetic shielding design.

[0047] Furthermore, the present application also includes: performing energy consumption analysis based on the electromagnetic wave generation frequency of the first layout position and the electromagnetic wave generation power of the first layout position to obtain a first energy consumption prediction value; until performing energy consumption analysis based on the electromagnetic wave generation frequency of the Nth layout position and the electromagnetic wave generation power of the Nth layout position to obtain an Nth energy consumption prediction value; sorting the first layout position to the Nth layout position from small to large according to the first energy consumption prediction value to the Nth energy consumption prediction value to obtain a layout position sorting result; using the energy consumption prediction value as a fitness value, optimizing the layout position based on the layout position sorting result to obtain the layout position of the electromagnetic wave generator, wherein the layout position of the electromagnetic wave generator includes the electromagnetic wave generation frequency and the electromagnetic wave generation power.

[0048] Specifically, the frequency of electromagnetic wave generation refers to the number of waves generated per second, while the power of electromagnetic wave generation refers to the energy output of electromagnetic waves, which is used to affect the energy consumption of the electromagnetic wave generator. Energy consumption analysis is performed based on the frequency of electromagnetic wave generation at the first layout position and the power of electromagnetic wave generation at the first layout position, and the energy consumption prediction value of the layout position is calculated, that is, the expected energy consumption of the electromagnetic wave generator under the frequency and power settings, to obtain the first energy consumption prediction value.

[0049] According to the method for obtaining the first energy consumption prediction value corresponding to the first layout position, the energy consumption prediction values ​​of multiple layout positions are predicted in sequence, until the energy consumption analysis is performed according to the electromagnetic wave generation frequency and the electromagnetic wave generation power of the Nth layout position, and the energy consumption prediction value of the layout position is calculated, that is, the expected energy consumption of the electromagnetic wave generator under the frequency and power settings, and the Nth energy consumption prediction value is obtained. The electromagnetic wave generation frequency and power value of each layout position will affect the energy consumption of the position, and the energy consumption prediction values ​​of different layout positions are different.

[0050] According to the order from the first energy consumption prediction value to the Nth energy consumption prediction value from small to large, the first layout position to the Nth layout position are sorted to obtain the layout position sorting result, and then the energy consumption of multiple layout positions is determined, thereby providing a reference for subsequent optimization configuration.

[0051] The predicted energy consumption value is used as the fitness value, and the predicted energy consumption value of each layout position is used as the standard for evaluating the pros and cons of the layout position as the fitness value. The fitness value reflects the pros and cons of the electromagnetic wave generator configuration of a certain layout. The smaller the fitness value, the lower the energy consumption and the better the performance, and vice versa.

[0052] According to the layout position sorting results, the layout position is optimized to determine the most suitable frequency and power combination to ensure that the equipment achieves the best balance between energy efficiency and performance, and obtain the layout position of the electromagnetic wave generator. Among them, the layout position of the electromagnetic wave generator includes the electromagnetic wave generation frequency and electromagnetic wave generation power. The frequency and power settings of the electromagnetic wave generator will directly affect the propagation characteristics and energy consumption of the electromagnetic wave. The electromagnetic wave generation frequency determines the number of electromagnetic wave oscillations per second, while the electromagnetic wave generation power determines the amount of energy released by the electromagnetic wave.

[0053] Furthermore, the present application also includes: extracting a first number of layout positions in positive order based on the layout position sorting result, wherein the first number is equal to the total number of layout positions * 0.06; extracting a second number of layout positions in reverse order based on the layout position sorting result, wherein the second number is greater than or equal to the total number of layout positions * 0.12; taking the first number of layout positions as the target point and the second number of layout positions as the starting point, according to a preset search step, obtaining an expanded layout position; traversing the configuration of the electromagnetic wave generation frequency and the electromagnetic wave generation power of the expanded layout position, and obtaining the electromagnetic wave generation frequency of the expanded layout position and the electromagnetic wave generation power of the expanded layout position. generating power; performing energy consumption analysis according to the electromagnetic wave generating frequency of the expanded layout position and the electromagnetic wave generating power of the expanded layout position to obtain an energy consumption prediction value of the expanded layout position; replacing the first sequence number position of the layout position sorting result with the energy consumption prediction value of the expanded layout position which is less than the first energy consumption prediction value until the minimum value of the Nth energy consumption prediction value, and performing a cyclic optimization; otherwise, updating the expanded layout position; when a preset number of iterations is met, obtaining the layout position of the electromagnetic wave generator according to the first sequence number position, wherein the layout position of the electromagnetic wave generator includes the electromagnetic wave generating frequency and the electromagnetic wave generating power.

[0054] Specifically, based on the sorting result of the layout positions, the first number of layout positions are extracted in positive order, that is, a portion of the layout positions ranked high are selected in order from small to large. The first number is equal to the total number of layout positions multiplied by 0.06, that is, the first number is calculated by multiplying the total number of layout positions by a ratio (here 6%), and the layout positions accounting for 6% of the total layout positions are selected as target points.

[0055] Based on the layout position sorting result, a second number of layout positions are extracted in reverse order, that is, a portion of the layout positions ranked lower are selected in order from large to small, wherein the second number is greater than or equal to the total number of layout positions multiplied by 0.12, and the proportion of the selected layout positions is greater than or equal to 12% of the total number of layout positions.

[0056] Taking the first number of layout positions as the target point and the second number of layout positions as the starting point, and obtaining the expanded layout positions according to the preset search step length, means that between the first number of layout positions and the second number of layout positions, according to the set search step length (the step length refers to the search interval or the moving distance), the layout positions are gradually expanded to form new expanded layout positions. The expansion process is performed between the target point and the starting point to find the optimal configuration between the layout positions.

[0057] Visit each point in the extended layout position in turn, configure the electromagnetic wave generation frequency and the electromagnetic wave generation power, obtain the electromagnetic wave generation frequency and the electromagnetic wave generation power at the extended layout position, which are used to influence the propagation characteristics and energy consumption of the electromagnetic waves to ensure that electromagnetic waves that meet the requirements can be generated at each position.

[0058] Energy consumption analysis is performed based on the electromagnetic wave generation frequency and the electromagnetic wave generation power at the expanded layout position, that is, under the electromagnetic wave generation frequency and power configured for each expanded layout position, the energy consumption prediction value of the layout position is calculated to obtain the energy consumption prediction value of the expanded layout position. Energy consumption analysis can predict the actual energy consumption level of each layout position by calculating the energy consumption of the electromagnetic wave generator based on different frequency and power settings.

[0059] The energy consumption prediction value of the expanded layout position is compared with the minimum value from the first energy consumption prediction value to the Nth energy consumption prediction value. If the energy consumption prediction value of the expanded layout position is less than the minimum value, the first serial number position of the layout position sorting result is replaced with the expanded layout position, and the next round of optimization cycle is started to obtain the most energy-saving layout configuration.
