Description

Technical Field

[0001] This invention relates to the field of interference equipment control technology, specifically a method and system for controlling regional electromagnetic interference equipment. Background Technology

[0002] Electromagnetic interference devices (commonly known as "signal jammers") emit strong noise or modulated signals in specific frequency bands, which can prevent receivers such as mobile phones, WiFi, and GPS from correctly interpreting communication signals from background noise, thus achieving the effect of "signal disconnection".

[0003] Signal shielding is generally not permitted in normal scenarios. However, there are special scenarios where shielding is required, and with authorization, signal shielding can be performed on a specific area. However, existing shielding processes are mostly simplistic, typically involving first dividing the area into zones and then installing electromagnetic interference (EMI) devices to shield a single area. While this approach is logically simple, its cost-effectiveness is very low, especially in large-area shielding scenarios where a specific shielding range is difficult to define. To achieve better shielding results, multiple signal shielding devices need to be installed and activated, and these devices require high-intensity operation, further wasting resources. Therefore, the technical problem this invention aims to solve is how to provide a signal shielding device control scheme that better suits the actual environment. Summary of the Invention

[0037] The subsequences are classified into zero and one according to a preset signal strength threshold; when the signal strength reaches the signal strength threshold, the corresponding element is marked as 0, and when the signal strength does not reach the signal strength threshold, the corresponding element is marked as 1.

[0038] Calculate the distance between elements that are equal to 1, and group them into one category if the distance is less than a preset distance threshold.

[0039] When the number of elements of a certain type reaches a preset threshold, the nearest interference point is queried, and the additional interference intensity is determined based on the average difference between the signal strength and the information strength threshold.

[0041] Read all reference interference strengths and send them to the corresponding interference devices;

[0042] When additional interference strength is generated, the additional interference strength is sent to the corresponding interference device, and the sending time is recorded synchronously.

[0043] The transmission time is used as the starting point limit for the time span in which the next additional interference intensity is generated.

[0044] The present invention also provides a regional electromagnetic interference equipment control system, the system comprising:

[0053] The radiation analysis unit is used to randomly select points from the sampling points as interference points, and to create a radiation function with the interference point as the center. The radiation function is used to characterize the degree of interference of the interference point in each point in the interference area under the condition of preset interference intensity.

[0054] The scheme output unit is used to repeatedly execute the point selection process. When the radiation function meets the preset conditions, it outputs the interference scheme.

[0055] The optimization unit is used to repeatedly execute the scheme generation process a preset number of times, optimize the obtained interference schemes, and determine the final scheme; wherein the optimization conditions include at least a quantity condition.

The resulting solution is in a state that perfectly meets the requirements, with minimal resource waste and extremely high cost utilization. Attached Figure Description

[0063] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

[0064] Figure 1 A general flowchart of the regional electromagnetic interference equipment control method is shown.

[0065] Figure 2 A structural diagram of the regional electromagnetic interference equipment control system is shown. Detailed Implementation

[0066] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0067] Figure 1 This is a general flowchart of a method and system for controlling regional electromagnetic interference equipment. In this embodiment of the invention, a method for controlling regional electromagnetic interference equipment includes:

[0068] Step S100: Receive boundary information input by the user, determine the area to be interfered with, and randomly set interference points in the area to be interfered with;

[0069] The area to be interfered with is a finite area, and the user needs to define its boundaries. The boundary information input by the user is received to determine the area to be interfered with. Some locations are selected in the area to be interfered with as interference points. Signal jamming devices are installed at the interference points to interfere with the signals in the area to be interfered with. Existing equipment can be used for the signal jamming devices.

[0070] Step S200: Receive the zoning information containing interference levels input by the user, and determine the reference interference intensity of each interference point based on the zoning information containing interference levels.

[0071] The area to be interfered with is a relatively large area containing multiple smaller areas that require different levels of signal shielding. The system receives zoning information containing interference levels from the user, that is, the user inputs which smaller areas require what level of shielding. The higher the interference level, the higher the required level of shielding. Based on the zoning information containing interference levels, the baseline interference level for each interference point can be determined.

[0072] Step S300: Real-time detection of signals based on preset measurement points, acquisition of signal strength containing location and time labels, and creation of a signal layer sequence; the layers in the signal layer sequence are used to characterize the signal strength distribution within the area to be interfered with;

[0073] The equipment control process of this invention occurs during the testing phase. After determining the baseline interference level, some measurement points are set in the area to be interfered with. Measuring instruments are installed at the measurement points to detect signals in real time, acquire signal strengths containing location and time tags, and statistically analyze these signal strengths to obtain a signal layer sequence. The location tags in this invention are generally two-dimensional, that is, when testing is conducted on the ground, the location tags have two dimensions and time has one dimension, resulting in a three-dimensional matrix. If cost permits, testing can be conducted in three-dimensional space, in which case the location tags have three dimensions and time has one dimension, resulting in four dimensions, and the signal layer sequence becomes a four-dimensional matrix.

[0074] Step S400: Determine the additional interference intensity at each interference point based on the signal layer sequence;

[0075] By identifying and analyzing the signal layer sequence, some locations that clearly do not meet the requirements can be determined (the signal strength is still high, but the shielding level is very low). For these locations that clearly do not meet the requirements, an additional level of interference is set for the nearby interference points, so that they can perform the shielding task under a higher intensity.

[0076] Step S500: Generate control commands pointing to the jamming device based on the reference interference strength and the additional interference strength;

[0077] After the above processing, interference equipment is installed at the interference point. After the reference interference intensity and additional interference intensity at the interference point are determined, they are converted into control commands and sent to the interference equipment. The relationship between interference intensity and control commands is not complicated and belongs to the free function of the equipment, so it will not be elaborated here.

[0078] Regarding step S100, the steps of receiving boundary information input by the user, determining the area to be interfered with, and randomly setting interference points in the area to be interfered with include:

[0079] Receive the boundary coordinate points input by the user, fit the boundary coordinate points, and determine the area to be interfered with;

[0080] Sampling points are determined within the area to be interfered with based on a preset first interval step size;

[0081] Randomly select points from the sampling points as interference points, and create a radiation function with the interference point as the center. The radiation function is used to characterize the degree of interference of each point in the interference area under the condition of preset interference intensity.

[0082] The point selection process is executed repeatedly. When the radiation function meets the preset conditions, the interference scheme is output.

[0083] The scheme generation process is repeated a preset number of times, and the best solution is selected from the obtained interference schemes to determine the final solution; the optimization conditions include at least a quantity condition.

[0084] The above content defines the process for setting up interference points. The conventional approach involves creating a grid within the area to be interfered with, with rectangular grid cells, using the grid nodes as interference points, and then installing the interference equipment. However, this method results in fixed equipment locations, making it easy to identify patterns and thus the method of targeting easily known. Therefore, the above content provides a random, hidden setting method, as follows:

[0085] The system receives boundary coordinates input by the user, fits these coordinates to determine the area to be interfered with, and determines sampling points within this area according to a preset first interval step size. In traditional solutions, equipment is installed at the sampling points, resulting in a larger first interval step size. However, in this solution, the first interval step size is very small; each point serves as both a sampling point and a potential interference point. Points are randomly selected from the sampling points as interference points. A radiation function is created centered on these interference points. The radiation function is as follows:

[0086] In the formula, Interference points At the point The degree of interference at the location, The preset correction factor. Interference points and points distance, The preset interference intensity at the interference point.

[0087] The radiation function represents the impact of the interfering device on its surroundings. Each time an interference point is selected, a new radiation function is generated, and the state of the entire area to be interfered with will change. The point selection process is repeated, and when the radiation functions of all interference points meet the preset conditions, the interference scheme is output.

[0088] The process of generating interference schemes is also a cyclical process. It is executed a preset number of times to obtain a preset number of schemes. Among the obtained interference schemes, the optimization is carried out to determine the final scheme. The simplest condition for optimization is to select the interference scheme with the fewest interference points as the final scheme. If the number is the same, any one can be selected (for example, the scheme with the lower installation cost).

[0089] Specifically, the step of outputting the interference scheme when the radiation function meets the preset conditions in the cyclic execution point selection process includes:

[0090] Read the radiation function of the existing interference points, and calculate the superposition function value of each sampling point based on the read radiation function;

[0091] The minimum value is selected from the superimposed function values ​​at each sampling point, and then compared with the minimum value and the preset threshold.

[0092] If the maximum value does not reach the preset threshold, proceed with the selection process for the next interference point.

[0093] When the minimum value reaches the preset threshold, the process of selecting interference points stops, and the selected interference points are output as the interference scheme.

[0094] The above describes the process of selecting interference points. The radiation function of existing interference points is read, and the function value of each sampling point is calculated based on the read radiation function. For example, if three interference points are selected, each location (sampling point) in the area to be interfered with will have three function values. These three function values ​​are superimposed to obtain a superimposed function value. The minimum value is selected from the superimposed function values ​​of all sampling points, which is the weakest point in the entire area to be interfered with. The minimum value is compared with a preset threshold. When it is large enough to reach the preset threshold, the selection process of interference points stops, and the selected interference points are output as the interference scheme. If the threshold is not reached, the selection process of the next interference point is executed.

[0095] It should be noted that the selection of interference points must be random, and the location must be known only to the interfering party, thus improving the level of security.

[0096] Regarding step S200, the step of receiving the zoning information containing interference levels input by the user, and determining the reference interference intensity of each interference point based on the zoning information containing interference levels, includes:

[0097] Receive user input of sub-region boundaries and interference levels for each sub-region, and classify the sub-regions according to the interference levels;

[0098] Based on the order of interference level from low to high, each type of sub-region is read sequentially;

[0099] For each type of sub-region, calculate the distance between the center point of each sub-region and the center point of the interference region, and read the sub-regions in order of increasing distance;

[0100] Find the nearest interfering point to the center point of the sub-region and use it as the point to be determined.

[0101] Query the required intensity corresponding to the interference level of the sub-region, query the minimum interference intensity of the activated interference point in the sub-region, calculate the difference between the required intensity and the minimum interference intensity, and determine the reference interference intensity of the undetermined point based on the difference.

[0102] The process is repeated until the interference intensity at any point within the interference area reaches the required intensity.

[0103] In one example of the technical solution of this invention, the process of determining the baseline interference intensity is described. The process involves receiving user input of sub-region boundaries and the interference level of each sub-region. Sub-regions are then classified according to their interference levels, which are gradient values ​​such as level one, level two, and level three. Higher levels require higher interference intensity. Sub-regions are classified according to their interference levels, and then each category of sub-regions is analyzed sequentially based on the order of interference levels from low to high. This ensures that sub-regions with lower requirements are satisfied first. Satisfying low requirements will shield other regions to some extent, but their requirements may not yet be met. If the process starts with the sub-region with the highest requirement, the surrounding areas will also have a high degree of interference, resulting in a waste of resources.

[0104] For each type of sub-region, calculate the distance between the center point of each sub-region and the center point of the interference region. Read the sub-regions in order of increasing distance, that is, start from the center of the region to be interfered with and proceed outwards. This is similar to the above order in principle, allowing the interference intensity of the interference points that have an impact on the surrounding area to be set earlier.

[0105] For the selected sub-region, query the nearest interference point to the center of the sub-region and use it as a pending point. Query the required intensity corresponding to the interference level of the sub-region, and query the minimum interference intensity of the activated interference points within the sub-region. Calculate the difference between the required intensity and the minimum interference intensity (required intensity - minimum interference level). If it is greater than zero, it means the requirement has not yet been met. In this case, determine an increment based on the difference and adjust the current intensity of the interference point. If it is less than zero, it means the minimum interference intensity also meets the requirement. In this case, the intensity of the interference point does not need to be changed.

[0106] Continue executing the above process until the interference intensity at any point within the interference area reaches the corresponding required intensity.

[0107] Regarding step S300, the step of detecting signals in real time based on preset measurement points, obtaining signal strengths containing location and time labels, and creating a signal layer sequence includes:

[0108] The measurement points are determined within the area to be interfered with based on the preset second interval step size;

[0109] Install signal detection equipment at the measurement points to obtain the signal strength containing location and time tags based on a preset frequency;

[0110] Group the signal strengths within the same time range into one category, arrange the obtained signal strengths according to the location labels, and create a signal layer with time labels;

[0111] Arrange the signal layers in chronological order to obtain a signal layer sequence.

[0112] In one example of the technical solution of this invention, the process of generating a signal layer sequence is described. Measurement points are determined in the area to be interfered with according to a preset second interval step size. This is similar to the process of generating sampling points, except that the distance between the points is different. This can be compared with the grid function in existing software. Signal detection equipment is installed at the measurement points to obtain the signal strength containing location and time labels based on a preset frequency. The higher the signal strength, the lower the interference strength. The signal strengths within the same time range are grouped into one category. The signal strengths obtained are arranged according to the location labels to create a signal layer containing time labels. The signal layer is a spatial matrix (two-dimensional or three-dimensional). The signal layers are arranged in chronological order to obtain a signal layer sequence (three-dimensional or four-dimensional).

[0113] Regarding step S400, the step of determining the additional interference intensity of each interference point based on the signal layer sequence includes:

[0114] The signal layer sequence is truncated according to a preset time span; the time span ends at the current time and the time length is a preset value.

[0115] The subsequences are classified into zero and one according to a preset signal strength threshold; when the signal strength reaches the signal strength threshold, the corresponding element is marked as 0, and when the signal strength does not reach the signal strength threshold, the corresponding element is marked as 1.

[0116] Calculate the distance between elements that are equal to 1, and group them into one category if the distance is less than a preset distance threshold.

[0117] When the number of elements of a certain type reaches a preset threshold, the nearest interference point is queried, and the additional interference intensity is determined based on the average difference between the signal strength and the information strength threshold.

[0118] The process of determining the additional interference intensity is essentially a "gap filling" process. Subsequences are extracted from the signal layer sequence based on a preset time span. This time span is a period of time, calculated by reading backwards from the current time. After extracting the subsequences, they are classified into zero-one categories based on a preset signal strength threshold. This zero-one classification determines which times and locations have sufficiently high signal strength, reflecting which times and locations have insufficient interference strength. The distance between elements that are 1 is calculated; if the distance is less than a preset distance threshold, they are grouped together. This is clustering elements based on spatial location. When the number of elements in a certain category reaches a preset threshold, it indicates that the interference intensity within a small area is insufficient over a period of time. In this case, the nearest interference point (the one furthest from the center of the small area) is queried, and the additional interference intensity is determined based on the average difference between the signal strength and the information strength threshold.

[0119] Regarding step S500, the step of generating control commands directed to the jamming device based on the reference interference strength and the additional interference strength includes:

[0120] Read all reference interference strengths and send them to the corresponding interference devices;

[0121] When additional interference strength is generated, the additional interference strength is sent to the corresponding interference device, and the sending time is recorded synchronously.

[0122] The transmission time is used as the starting point limit for the time span in which the next additional interference intensity is generated.

[0123] Once the baseline interference strength and the additional interference strength are determined, they are converted into control commands and sent to the interference equipment. The additional interference level is a supplementary process. When the additional interference strength is sent to the corresponding interference equipment, the sending time is recorded synchronously. This is because the interference state of the entire area to be interfered with will change every time an additional interference strength is generated. Therefore, when determining the time span, a higher priority starting point is needed. That is, when determining the time period backward from the current time, the maximum time starting point limit can be reached.
