Description

Technical Field

[0001] This invention relates to the field of mobile phone signal interference, and in particular to a method and system for networking multiple jammers to achieve multi-mode communication signal interference. Background Technology

[0002] In existing technologies, when jammers are deployed in small venues, the placement points are often quite arbitrary. This leads to a series of problems, such as inaccurate interference range or over-coverage, with some areas not being interfered with. When jammers are deployed in large venues, using only a single jammer to shield the signal may not be able to cover the entire venue, or the placement of a single jammer may have a strong radiation effect on people near the jammer. Furthermore, it is impossible to accurately control whether interference occurs at a specific location.

[0003] At this point, multiple jammers need to be used for integrated jamming. In the current technology, how to set up jammers in large venues and the distance between jammers are often determined by experienced workers on-site. This not only leads to the same problems as setting up jammers in small venues, but also causes over-coverage of interference due to inaccurate control of the spacing between multiple jammers. This increases radiation and affects normal communication in the surrounding unshielded areas, or there are areas between jammers where there is no interference, causing the jamming to fail.

[0004] Therefore, it is necessary to propose an adaptive multi-jammer networking method and system for large venues, so as to reduce the cost of setting up jamming systems, improve the efficiency of jammer networking, and realize refined management of jamming areas. Summary of the Invention

[0005] To address one or more technical problems in the background art, the present invention provides a multi-jammer networking method for implementing multi-mode communication signal interference, comprising:

[0006] S1: Obtain spatial information of the location to be deployed, divide the location to be deployed into a set of multiple regions according to the preset regional division rules, perform operator signal strength detection on all regions in the set of regions, sort all regions from largest to smallest according to the operator frequency band signal with the highest signal strength, thereby generating A1 deployment point set. The information of each point in the A1 deployment point set includes the location coordinate information of the region and its operator signal strength information.

[0007] S2: Select the signal point with the highest intensity in the A1 deployment point set as the first deployment point, obtain the jammer information, and calculate the interference distance and actual coverage of the first deployment point based on the jammer information and the information of the first deployment point. The jammer information includes the transmit power information of the frequency band of the jammer's antenna output port.

[0008] S3: Based on the regional set information and the actual coverage of the first deployment point, select the signal points in the A1 deployment point set that are not covered by the first deployment point, that is, delete the location points covered by the interference signal of the first deployment point from the A1 deployment point set to obtain the A2 deployment point set.

[0009] S4: Select the signal point with the highest strength in the A2 deployment point set as a temporary second deployment point. Obtain the interference distance and actual coverage range of the temporary second deployment point based on the jammer information and the information of the temporary second deployment point. Determine whether the temporary second deployment point overlaps with the first deployment point and whether the overlap range is acceptable based on the preset overlap judgment formula. If it does, set the temporary second deployment point as the second deployment point. If it is unacceptable, set the signal point with the second highest signal strength in the A2 deployment point set as the temporary second deployment point and continue to use the overlap judgment formula to judge until a second deployment point that meets the condition is found. The overlap judgment formula is L1+L2-H≤T, where L1 is the interference distance of the first deployment point, L2 is the interference distance of the second deployment point, H is the distance between the first deployment point and the second deployment point, and T is the acceptable overlap range distance.

[0010] S5: Based on the area set information and according to the actual coverage of the second deployment point, select the signal points in the A2 deployment point set that are not covered by the second deployment point, and obtain the updated A2 deployment point set;

[0011] S6: Determine whether the set of points in A2 is not empty. If it is empty, end the network formation. If not, jump to step S4 and repeat steps S4-S6.

[0012] According to one aspect of the invention, the acceptable overlap range distance in the overlap determination formula is one of 2, 3, 4, and 5, with the unit being meters.

[0013] According to one aspect of the present invention, an optimized set of locations where jammers need to be placed can be derived. Furthermore, remote switching control of the jammers at each placement point can be achieved by controlling the jammers at each placement point.

[0014] According to one aspect of the present invention, the formula for obtaining the interference distance of the first arrangement point is:

[0015] D=10^((PYZ-20*LOG10(F)) / 20);

[0016] Where D is the interference distance, in km;

[0017] P represents the output power of a certain frequency band channel of the jammer, in dBm.

[0018] Y represents the air interface operator signal strength of this frequency band in the area where interference is required, in dBm.

[0019] Z represents the signal strength emitted by the jammer in the interference zone, which is greater than the operator's air interface signal strength, expressed in dBm.

[0020] F represents the frequency of a certain band of the jammer, in GHz.

[0021] To address one or more technical problems in the background art, the present invention provides a multi-jammer networking system for implementing multi-mode communication signal interference, comprising: a deployment point set acquisition module, a jammer deployment point determination module, a deployment point set update module, an overlap range judgment module, a jammer deployment point storage module, and a jammer deployment point display module; wherein;

[0022] The deployment point set acquisition module: acquires the spatial information of the site to be deployed, divides the site to be deployed into a set of multiple areas according to a preset area division rule, performs operator signal strength detection on all areas in the set of areas, sorts all areas from largest to smallest according to the operator frequency band signal with the highest signal strength, thereby generating a deployment point set. The information of each point in the deployment point set includes the location coordinates of the area and its operator signal strength information.

[0023] The jammer placement point determination module: selects the signal point with the highest signal strength from the current placement point set as a temporary jammer placement point; calculates the interference distance and coverage area of ​​the temporary jammer placement point based on the jammer information and the information of the temporary jammer placement point, where the jammer information includes the transmit power information of the jammer's antenna output port frequency band; if the jammer placement point storage module does not store any determined jammer placement points, then the temporary jammer placement point is determined as a jammer placement point; if the jammer placement point storage module stores determined jammer placement points, then the information of the temporary jammer placement point and its coverage area, as well as the information of the determined jammer placement point and its coverage area stored in the jammer placement point storage module, are sent to the overlap range judgment module; the jammer placement point is determined based on the judgment result returned by the overlap range judgment module; if the judgment result is acceptable, then the temporary jammer placement point is taken as a determined jammer placement point; if the judgment result is unacceptable, then the signal point with the second highest signal strength is selected from the current placement point set as a temporary jammer placement point, and the above determination process is repeated.

[0024] The deployment point set update module: Based on the area set information and the actual coverage range of the determined jammer deployment points stored in the jammer deployment point storage module, selects the signal points not covered by the jammer deployment points in the deployment point set to obtain the updated deployment point set.

[0025] The overlap range determination module: determines whether the temporary jammer placement point and the determined jammer placement point have an overlapping area and whether the overlap range is acceptable according to a preset overlap determination formula, and sends the result to the jammer placement point determination module; wherein, the overlap determination formula is L1+L2-H≤T, where L1 is the interference distance of the determined jammer placement point, L2 is the interference distance of the temporary jammer placement point, H is the distance between the determined jammer placement point and the temporary jammer placement point, and T is the acceptable overlap range distance;

[0026] The jammer placement point storage module stores the jammer placement point information and its coverage area information determined by the jammer placement point determination module.

[0027] The jammer placement point display module displays the jammer placement point information and its coverage area information stored in the jammer placement point storage module.

[0028] The system also includes a remote control module, which can remotely control the on / off switching of the jammers at each deployment point.

[0029] The acceptable overlap range distance in the overlap range determination module is one of 2, 3, 4, or 5 meters.

[0030] The formula for obtaining the interference distance of the first deployment point in the first deployment point influence range acquisition module is as follows:

[0031] D=10^((PYZ-20*LOG10(F)) / 20);

[0032] Where D is the interference distance, in km;

[0033] P represents the output power of a certain frequency band channel of the jammer, in dBm.

[0034] Y represents the air interface operator signal strength of this frequency band in the area where interference is required, in dBm.

[0035] Z represents the signal strength emitted by the jammer in the interference zone, which is greater than the operator's air interface signal strength, expressed in dBm.

[0036] F represents the frequency of a certain band of the jammer, in GHz.

[0037] Based on this, the beneficial effects of the present invention are as follows:

[0044] Figure 1 A flowchart illustrating a multi-jammer networking method for implementing multi-mode communication signal interference according to the present invention is shown below. Figure 1 As shown, a multi-jammer networking method for implementing multi-mode communication signal interference according to the present invention includes the following steps:

[0045] S1: Obtain the spatial information of the location to be deployed, divide the location to be deployed into a set of multiple areas according to the preset area division rules, perform operator signal strength detection on all areas in the set of areas, sort all areas from largest to smallest according to the operator frequency band signal with the highest signal strength, thereby generating the A1 deployment point set. The information of each point in the A1 deployment point set includes the location coordinate information of the area and its operator signal strength information.

[0046] S2: Select the signal point with the highest intensity in the A1 deployment point set as the first deployment point, obtain the jammer information, and calculate the interference distance and actual coverage of the first deployment point based on the jammer information and the information of the first deployment point. The jammer information includes the transmit power information of the frequency band of the jammer's antenna output port.

[0047] S3: Based on the area set information and the actual coverage of the first deployment point, select the signal points in the A1 deployment point set that are not covered by the first deployment point, that is, delete the location points covered by the interference signal of the first deployment point from the A1 deployment point set to obtain the A2 deployment point set.

[0048] S4: Select the signal point with the highest strength in the A2 deployment point set as a temporary second deployment point. Obtain the interference distance and actual coverage range of the temporary second deployment point based on the jammer information and the information of the temporary second deployment point. Determine whether the temporary second deployment point overlaps with the first deployment point and whether the overlap range is acceptable based on the preset overlap judgment formula. If it does, set the temporary second deployment point as the second deployment point. If it is unacceptable, set the signal point with the second highest signal strength in the A2 deployment point set as the temporary second deployment point and continue to use the overlap judgment formula to judge until a second deployment point that meets the condition is found. The overlap judgment formula is L1+L2-H≤T, where L1 is the interference distance of the first deployment point, L2 is the interference distance of the second deployment point, H is the distance between the first deployment point and the second deployment point, and T is the acceptable overlap range distance.

[0049] S5: Based on the area set information and the actual coverage of the second deployment point, select the signal points in the A2 deployment point set that are not covered by the second deployment point, and obtain the updated A2 deployment point set.

[0050] S6: Determine whether the set of points in A2 is not empty. If it is empty, end the network formation. If not, jump to step S4 and repeat steps S4-S6.

[0051] According to one embodiment of the present invention, the acceptable overlap range distance in the overlap judgment formula is one of 2, 3, 4, and 5, and the unit is meters.

[0052] According to one embodiment of the present invention, remote switching control of the jammers at each deployment point can be achieved by controlling the jammers at each deployment point.

[0053] According to one embodiment of the present invention, the formula for obtaining the interference distance of the first arrangement point is:

[0054] D=10^((PYZ-20*LOG10(F)) / 20);

[0055] Where D is the interference distance, in km;

[0056] P represents the output power of a certain frequency band channel of the jammer, in dBm.

[0057] Y represents the air interface operator signal strength of this frequency band in the area where interference is required, in dBm.

[0058] Z represents the signal strength emitted by the jammer in the interference zone, which is greater than the operator's air interface signal strength, expressed in dBm.

[0059] F represents the frequency of a certain band of the jammer, in GHz.

[0060] According to one embodiment of the present invention, in large venues, such as large conference rooms, it is often impossible to accurately interfere with the conference room signals by deploying a single high-power jammer. Therefore, the present method is required to deploy multiple jammers in a network manner in large conference rooms to achieve accurate interference at each location.

[0061] First, spatial information of the large conference room is obtained, including its area. The conference room is divided into multiple 2m×2m areas. Based on the frequency bands of various operators, the signal strength of each area is measured multiple times under different operator frequency bands. The operator frequency band with the highest signal strength in the large conference room is selected. The areas are arranged in descending order of signal strength under that operator frequency band to form the A1 deployment point set. Each unit in the A1 deployment point set includes the location information and signal strength information of the area corresponding to that point. The point with the strongest signal strength in the A1 deployment point set is selected as the first deployment point. The interference distance and actual coverage area of ​​the first deployment point are calculated. After excluding the unit points included in the A1 deployment point set according to the actual coverage area of ​​the first deployment point, the points that cannot be covered are rearranged according to signal strength to obtain the A2 deployment point set. The point with the strongest signal strength in the A2 set is selected as the temporary deployment point. For the second deployment point, calculate the interference distance and actual coverage area of ​​the temporary second deployment point. Based on the actual coverage area of ​​the temporary second deployment point and the actual coverage area of ​​the first deployment point, determine whether the temporary second deployment point is the correct selection point. If the first deployment point and the temporary second deployment point have no overlapping area, then the temporary second deployment point is the correct selection point. If the first deployment point and the temporary second deployment point have overlapping area, but the overlapping area is acceptable, then the temporary second deployment point is also the correct selection point. However, if the overlapping area is unacceptable, then select the point with the second strongest signal from the A2 deployment point set as the new temporary second deployment point and continue to determine whether the new temporary second deployment point is the correct selection point. If it is correct, select points in the A2 deployment point set that can be covered based on the actual coverage area of ​​the second deployment point. After excluding these points, re-establish the A3 deployment point set and complete the jammer network deployment for the large conference room according to the above steps.

[0062] Furthermore, to achieve the aforementioned objectives, this invention also provides a multi-jammer networking system for interfering with multi-mode communication signals. Figure 2 A schematic diagram illustrating a multi-jammer networking system for implementing multi-mode communication signal interference according to the present invention is shown below. Figure 2As shown, a multi-jammer networking system for implementing multi-mode communication signal interference according to the present invention includes: a deployment point set acquisition module, a jammer deployment point determination module, a deployment point set update module, an overlap range judgment module, a jammer deployment point storage module, and a jammer deployment point display module.

[0063] The deployment point set acquisition module is used to: acquire the spatial information of the site to be deployed, divide the site to be deployed into a set of regions consisting of multiple regions according to a preset regional division rule, perform signal strength detection on each region in the region set for each operator's operating frequency band, sort all regions from largest to smallest according to the operator's frequency band signal with the highest signal strength, thereby generating a deployment point set. The information of each point in the deployment point set includes the location coordinates of the region and its operator signal strength information.

[0064] The jammer placement point determination module is used to: select the signal point with the highest signal strength from the current placement point set as a temporary jammer placement point; calculate the interference distance and coverage area of ​​the temporary jammer placement point based on the jammer information and the information of the temporary jammer placement point, where the jammer information includes the transmit power information of the jammer's antenna output port frequency band; if the jammer placement point storage module does not store any determined jammer placement points, then the temporary jammer placement point is determined as a jammer placement point; if the jammer placement point storage module stores determined jammer placement points, then the information of the temporary jammer placement point and its coverage area, as well as the information of the determined jammer placement point and its coverage area stored in the jammer placement point storage module, are sent to the overlap range judgment module. The jammer placement point is determined based on the judgment result returned by the overlap range judgment module. If the judgment result is acceptable, then the temporary jammer placement point is used as a determined jammer placement point; if the judgment result is unacceptable, then the signal point with the second highest signal strength is selected from the current placement point set as a temporary jammer placement point, and the above determination process is repeated.

[0065] The deployment point set update module is used to: select signal points in the deployment point set that are not covered by the jammer deployment points, based on the area set information and the actual coverage range of the determined jammer deployment points stored in the jammer deployment point storage module, so as to obtain the updated deployment point set.

[0066] The overlap range determination module is used to: determine whether the temporary jammer placement point and the determined jammer placement point have an overlapping area and whether the overlap range is acceptable according to a preset overlap determination formula, and send the result to the jammer placement point determination module; wherein, the overlap determination formula is L1+L2-H≤T, where L1 is the interference distance of the determined jammer placement point, L2 is the interference distance of the temporary jammer placement point, H is the distance between the determined jammer placement point and the temporary jammer placement point, and T is the acceptable overlap range distance.

[0067] The jammer placement point storage module stores the jammer placement point information and its coverage area information determined by the jammer placement point determination module.

[0068] The jammer placement point display module displays the jammer placement point information and its coverage information stored in the jammer placement point storage module.

[0069] The system further includes a remote control module that can wirelessly control the jammers at each deployment point, enabling remote on / off control of the jammers at each deployment point.

[0070] According to one embodiment of the present invention, the acceptable overlap range distance in the overlap judgment formula is one of 2, 3, 4, and 5, and the unit is meters.

[0071] According to one embodiment of the present invention, remote switching control of the jammers at each deployment point can also be achieved by controlling the jammers at each deployment point.

[0072] According to one embodiment of the present invention, preferably, the formula for calculating the interference distance of the placement point is:

[0073] D=10^((PYZ-20*LOG10(F)) / 20);

[0074] Where D is the interference distance, in km;

[0075] P represents the output power of a certain frequency band channel of the jammer, in dBm.

[0076] Y represents the air interface operator signal strength of this frequency band in the area where interference is required, in dBm.

[0077] Z represents the signal strength emitted by the jammer in the interference zone, which is greater than the operator's air interface signal strength, expressed in dBm.

[0078] F represents the frequency of a certain band of the jammer, in GHz.

[0079] According to one embodiment of the present invention, in large venues, such as large conference rooms, it is often impossible to accurately interfere with the conference room signals by deploying a single high-power jammer. Therefore, the present method is required to deploy multiple jammers in a network manner in large conference rooms to achieve accurate interference at each location.

[0080] The deployment point set acquisition module first obtains the spatial information of the large conference room, including the spatial area of ​​the large conference room. The space of the large conference room is divided into multiple 2m×2m areas based on the frequency bands of various operators. The signal strength of each area in the above multiple areas is measured multiple times under different operator frequency bands. The operator frequency band with the highest signal strength in the large conference room is selected. The deployment points are arranged in descending order of the signal strength of each area measured under that operator frequency band to form the A1 deployment point set. A unit in the A1 deployment point set includes the location information and signal strength information of the area corresponding to that point.

[0081] According to the jammer placement point determination module, the point with the strongest signal strength in the A1 placement point set is selected as the first placement point. The interference distance and actual coverage range of the first placement point are calculated. After excluding the unit points included in the A1 placement point set according to the actual coverage range of the first placement point, the points that cannot be covered are rearranged according to the signal strength. According to the placement point set update module, the A2 placement point set is obtained. The point with the strongest signal strength in the A2 placement point set is selected as the temporary second placement point.

[0082] Based on the overlap range judgment module, the interference distance and actual coverage range of the temporary second placement point are calculated. The actual coverage range of the temporary second placement point is compared with that of the first placement point to determine if the temporary second placement point is the correct selection. If there is no overlap between the first and temporary second placement points, then the temporary second placement point is the correct selection. If there is an overlap, but the overlap is acceptable, then the temporary second placement point is also the correct selection. However, if the overlap is unacceptable, the second strongest signal point is selected from the A2 placement point set as the new temporary second placement point, and the determination of whether the new temporary second placement point is the correct selection is continued. If correct, points that can be covered from the A2 placement point set are selected based on the actual coverage range of the second placement point. After excluding these points, the A3 placement point set is re-established, and the jammer network deployment for the large conference room is completed according to the above steps.

[0083] The jammer deployment point storage module stores the jammer deployment point information and its coverage area information determined by the jammer deployment point determination module.

[0084] The jammer deployment point display module displays the jammer deployment point information and its coverage area information stored in the jammer deployment point storage module.

The deployment point set acquisition module: acquires the spatial information of the site to be deployed, divides the site to be deployed into a set of regions consisting of multiple regions according to a preset regional division rule, performs signal strength detection on each region in the set of regions for each operator's operating frequency band, sorts all regions in descending order of signal strength according to the operator's frequency band with the highest signal strength, thereby generating a deployment point set. The information of each point in the deployment point set includes the location coordinates of the region and its operator signal strength information. The jammer placement point determination module: selects the signal point with the highest signal strength from the current placement point set as a temporary jammer placement point; calculates the interference distance and coverage area of ​​the temporary jammer placement point based on the jammer information and the information of the temporary jammer placement point, where the jammer information includes the transmit power information of the jammer's antenna output port frequency band; if the jammer placement point storage module does not store any determined jammer placement points, then the temporary jammer placement point is determined as a jammer placement point; if the jammer placement point storage module stores determined jammer placement points, then the information of the temporary jammer placement point and its coverage area, as well as the information of the determined jammer placement point and its coverage area stored in the jammer placement point storage module, are sent to the overlap range judgment module; the jammer placement point is determined based on the judgment result returned by the overlap range judgment module; if the judgment result is acceptable, then the temporary jammer placement point is taken as a determined jammer placement point; if the judgment result is unacceptable, then the signal point with the second highest signal strength is selected from the current placement point set as a temporary jammer placement point, and the above determination process is repeated. The deployment point set update module: Based on the area set information and the actual coverage range of the determined jammer deployment points stored in the jammer deployment point storage module, selects the signal points not covered by the jammer deployment points in the deployment point set to obtain the updated deployment point set. The overlap range judgment module: determines whether the temporary jammer placement point and the determined jammer placement point have an overlapping area and whether the overlap range is acceptable according to a preset overlap judgment formula, and sends the result to the jammer placement point determination module; wherein, the overlap judgment formula is L1+L2-H≤T, where L1 is the interference distance of the determined jammer placement point, L2 is the interference distance of the temporary jammer placement point, H is the distance between the determined jammer placement point and the temporary jammer placement point, and T is the acceptable overlap range distance; The jammer placement point storage module stores the jammer placement point information and its coverage area information determined by the jammer placement point determination module. The jammer placement point display module displays the jammer placement point information and its coverage area information stored in the jammer placement point storage module. The system automatically deploys jammers by obtaining information about the jammers and the spatial information of the location to be deployed. The system also includes a remote control module, which can remotely control the on / off switching of the jammers at each deployment point by controlling the jammers at each deployment point. The formula for calculating the interference distance of the placement points is: D=10^((PYZ-20*LOG10(F)) / 20); Where D is the interference distance, in km; P represents the output power of a certain frequency band channel of the jammer, in dBm. Y represents the air interface operator signal strength of this frequency band in the area where interference is required, in dBm. Z represents the signal strength emitted by the jammer in the interference zone, which is greater than the operator's air interface signal strength, expressed in dBm. F represents the frequency of a certain band of the jammer, in GHz.
