Description

Technical Field

[0002] With the development of modern communication technology, there are more and more cases of cheating in exams using radio technology. The technical means are constantly being updated and have obvious commercial, professional and networked characteristics, which seriously undermine the social fairness and justice of the examination order. To prevent the use of radio technology for cheating in exams, we must first quickly detect the cheating signal, and then interfere with and suppress the cheating signal to prevent cheating from succeeding, and find the signal source through direction finding and positioning.

[0003] As for the retrieval and suppression of abnormal signals, the existing technology is now relatively mature. However, as for the acquisition of signal sources, it is more about gradually tracing according to the direction and strength of the detected abnormal signal to finally obtain the signal source. Since the direction of the signal will be reflected in multiple directions in a city with dense buildings, the method of gradually tracing according to the direction of the abnormal signal often requires staff to turn multiple times, and it is necessary to pay real-time attention to the direction, strength and other information of the abnormal signal, and manually judge the suspected location of the signal source, which consumes a lot of staff's time. In addition, the existing cheating methods have a long propagation distance of the emission source, which will further reduce the efficiency of the above-mentioned signal tracing. Summary of the Invention

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0061] As for the retrieval and suppression of abnormal signals, the existing technology is relatively mature. However, as for the acquisition of signal sources, it is more about gradually tracing according to the direction and strength of the detected abnormal signal to finally obtain the signal source. Since the direction of the signal will be reflected in multiple directions in a city with dense buildings, the method of gradually tracing according to the direction of the abnormal signal often requires staff to turn multiple times, and it is necessary to pay real-time attention to the direction, strength and other information of the abnormal signal, and manually judge the suspected location of the signal source, which consumes a lot of staff's time. In addition, the propagation distance of the emission source of the existing cheating means is relatively long, and the efficiency of the above-mentioned signal tracing will be further reduced. The present application proposes an Internet remote control cheating signal interception and processing system to promote the solution of the above-mentioned problems. Example 1

[0062] See Figure 1 , an Internet remote control cheating signal interception and processing system, comprising,

[0063] An acquisition frequency control module is used to set the frequency of signal acquisition according to the target area;

[0064] The frequency of signal acquisition is set according to the target area, including:

[0065] The target area is divided into at least three areas: a first target area, a second target area, and a third target area.

[0066] The signal influence circle is selected with the centers of the first target area, the second target area, and the third target area as the center and the effective distance as the radius.

[0067] Obtain building density information within the signal influence circle. Building density information = number of buildings ÷ area of ​​the signal influence circle;

[0068] Match the appropriate signal acquisition frequency according to the building density information.

[0069] If you are in a busy area of ​​the city with tall buildings and a complex electromagnetic environment, set a smaller scanning interval and monitor a slightly narrower frequency band. Divide the 400-650MHz band into three frequency bands: 400-430MHz (7.5kHz interval), 430-470MHz (7.5kHz interval), and 470-650MHz (50kHz interval) for time-sharing scanning. A complete scan of all frequency bands takes about 4.5 seconds.

[0070] If you are in the suburbs of a city or a university town with a good electromagnetic environment, then you can set a larger scanning interval and monitor a wider frequency band. Perform multi-band time-sharing scanning of 130MHz-850MHz, and fully scan all frequency bands once in about 5.5 seconds. This can not only quickly detect cheating signals, but also be used to discover new frequency bands that may be used for cheating.

[0071] The above-mentioned effective distance is defined as the distance between the emission source that generates the electromagnetic waves that affect the detection accuracy in the target area and the target area as the effective distance.

[0072] The signal discrimination module is used to determine whether the abnormal signal is the target signal. If so, it is intercepted and processed;

[0073] Determining whether an abnormal signal is a target signal includes:

[0074] Demodulate the abnormal signal and generate corresponding content, and determine whether the abnormal signal is the target signal by analyzing the content;

[0075] If the demodulated content is incomprehensible, the technical system of the abnormal signal is analyzed and compared with the legal frequency plan to determine whether the abnormal signal is the target signal. If the abnormal signal complies with the frequency plan and the frequency is assigned, it is a legal signal; otherwise, the abnormal signal is determined to be the target signal.

[0076] Obtain the signal direction of the target signal for tracing the source.

[0077] Determining whether an abnormal signal is a target signal also includes:

[0078] Record the electromagnetic environment in the target area and establish a spectrum archive to record the signal spectrum and the nature of the signal usage;

[0079] According to the set signal acquisition frequency, the signal is collected and compared with the spectrum archive. If the collected signal frequency is a legal frequency in the spectrum archive, the signal level detection is performed;

[0080] If the collected signal frequency does not exist in the archive, the signal will be judged as an abnormal signal;

[0081] If the measured level of the signal does not exceed the level marked in the spectrum archive, it is considered a legal signal; otherwise, it is considered an abnormal signal.

[0082] The signal tracing module obtains the signal source through tracing processing based on the signal information of the target signal;

[0083] Control terminal: connected with the acquisition frequency control module, abnormal signal acquisition module, signal discrimination module and signal tracing module, coordinating the modules to perform data processing.

[0084] By analyzing the building density in the target area based on its specific location, and considering the electromagnetic impact of the building density on the target area, the frequency of signal collection is reasonably planned to facilitate staff to obtain abnormal signals more effectively. Example 2

[0085] A method for intercepting and processing Internet remote control cheating signals,

[0086] See Figure 1-2 This embodiment is an improvement based on the first embodiment. Specifically, the signal source is obtained by tracing the signal information of the target signal, including:

[0087] Simultaneously tracking target signals within the first target area, the second target area, and the third target area;

[0088] If the three target areas acquire target signals at the same time, the position with equal distance from the center of the three target areas is determined as the target position; Figure 2 In the figure, the Z point position is the target position, and the straight line formed by the three target area centers and the target position is identified as the detection calibration line; as shown in the figure, line segment AZ, line segment CZ and line segment BZ are the three detection calibration lines.

[0089] Enter the target location, search for the target signal according to the search route, finally obtain the location of the signal source, and then search for the target signal at the location of the signal source.

[0090] The acquisition of the search route includes:

[0091] The centers of the first target area, the second target area, and the third target area are respectively used as vertices to enclose a triangular area to be detected, such as: Figure 2 In the figure, area ABC is the area to be tested.

[0092] Taking the target position as the starting point, draw perpendicular bisectors along the three enclosed sides of the area to be inspected to form ZF, ZE, and ZD, respectively, and divide the area to be inspected into a first detection area, a second detection area, and a third detection area corresponding to the first target area, the second target area, and the third target area, respectively;

[0093] That is, Figure 2 In the figure, area AFZD is the first detection area, area BDZE is the second detection area, and area CEZF is the third detection area;

[0094] Using the formula, building density = number of buildings ÷ area of ​​the detection area, calculate the building density of the first detection area, the second detection area, the first and third detection areas, and record them as G1, G2, and G3 respectively;

[0095] Compare the building densities of the three detection areas. Based on the building density, the first two detection areas are divided into primary detection areas and secondary detection areas in descending order. The boundary between the primary detection area and the secondary detection area is recorded as the detection boundary.

[0096] The area formed by the detection calibration line and the detection boundary in the main detection area is selected as the search area, and the target signal is searched with the target position as the starting point.

[0097] In this embodiment, the second detection area is taken as the main detection area, and the first detection area is taken as the secondary detection area.

[0098] Figure 2 In the search area, the area formed by BZ and ZD is the search area. Starting from point Z, the target signal is searched in the search area. Since the greater the building density, the better the signal blocking performance, based on this phenomenon, when searching for signals in the search area, the search should be biased towards ZB. The search process can be appropriately biased towards the search boundary ZD. If the building density in the first detection area is close to the building density in the second detection area, then when searching for signals in the search area, the search should be biased towards ZD.

[0099] Finally, the location of the signal source is obtained, and then the target signal at the location of the signal source is searched.

[0100] The above search method can quickly determine the target position close to the target signal, and then determine the search route for the target signal based on the building density of each detection area. Finally, the position of the target signal is searched within a small range, which can quickly narrow the target range and find the signal source relatively quickly. Example 3

[0101] This embodiment is a supplement to the first embodiment. According to the signal information of the target signal, the signal source is obtained by tracing the source, specifically including:

[0102] Simultaneously tracking target signals within the first target area, the second target area, and the third target area;

[0103] If two target areas acquire target signals at the same time, the center points of the two target areas are determined as the target positions;

[0104] Enter the target location, search for the target signal according to the search route, finally obtain the location of the signal source, and then search for the target signal at the location of the signal source.

[0105] If only one target area obtains the target signal, the direction and strength of the target signal are directly tracked to eventually obtain the location of the signal source, and then the target signal at the location of the signal source is searched. Example 4

[0106] See Figure 1-Figure 5 This embodiment is a further supplementary explanation of embodiment 2 or 3, specifically including: when a small area is identified as the location of the signal source, especially when the direction of the signal source is inside a certain building, there are two situations:

[0107] First, the signal source is inside the building, but it is difficult to determine the specific height of the signal source;

[0108] Secondly, the signal source is simply reflected from the building, and the exact location of the signal source needs to be re-determined. To facilitate solving the above problem, the following steps need to be performed:

[0109] Determine the type of environment where the signal source is located.

[0110] If the environment where the signal source is located is an open environment, S1 will directly search for the signal source.

[0111] S2 If the environment where the signal source is located is a closed environment, then,

[0112] S3 adds a mobile signal detection point; the mobile signal detection point can assemble the signal detection device on the drone and detect the signal by controlling the drone.

[0113] S4 uses the longitudinal depth of the center of the closed environment as the detection axis. The mobile signal detection point moves upward in a spiral from bottom to top around the detection axis and detects the direction of the target signal in real time. For details, please refer to Figure 3

[0114] S5 establishes a signal direction diagram of the mobile signal detection point on the plane; for details, please refer to Figure 4 or Figure 5 Schematic diagram of the motion path of the mobile signal detection point on the plane;

[0115] Establish a vertical signal direction diagram of the mobile signal detection point; for details, please refer to Figure 4 or Figure 5 , a schematic diagram of the longitudinal motion path of the mobile signal detection point;

[0116] S6 If the signal direction diagram of the mobile signal detection point on the plane is focused on one point, and the mobile signal detection point is also focused on one point in the longitudinal direction, that is, Figure 4 In the case shown in FIG, it is determined that the signal source is located in the closed environment, and the specific location of the signal source is determined according to the vertical signal direction diagram of the mobile signal detection point;

[0117] S7 If the signal direction diagram of the mobile signal detection point on the plane is discrete, or the mobile signal detection point is discrete in the longitudinal direction, that is, Figure 5 If the situation shown in , it is determined that the signal source is not in the closed environment,

[0118] S8 detects the location of other signal sources again and repeats steps S1-S6 until the specific location of the signal element is found.

[0119] Through the above method, it is possible to determine whether the target signal is in a closed building. If the signal direction schematic diagram of the mobile signal detection point on the plane is focused on one point, and the mobile signal detection point is also focused on one point in the longitudinal direction, it is determined that the signal source is located in the closed environment; and, based on the motion path schematic diagram of the mobile signal detection point in the longitudinal direction, the specific floor height where the signal source is located can be determined, so that the staff can quickly find the signal source. If the signal direction schematic diagram of the mobile signal detection point on the plane is discrete, or the mobile signal detection point is discrete in the longitudinal direction, it is determined that the signal source is not in the closed environment, so that the staff can quickly adjust the search target and find the signal source again.
