Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more specifically, to a method for detecting wireless communication interference. Background Art

[0002] Wireless communication refers to the technology of transmitting information between two or more points through electromagnetic waves (such as radio waves, microwaves, infrared rays, etc.) instead of wires or other tangible connections. In order to ensure the smooth transmission of wireless communication, interference detection of wireless communication is required to detect external interference and malicious interference.

Compared with the existing BSS algorithm based on the Newton iteration method, it is easier to find the global optimal solution and is not easy to fall into the local optimum, so that the generated decomposition matrix can effectively separate the estimated signal of the source signal from the observed signal, and then accurately analyze the interference of the estimated signal.

[0009] In a preferred embodiment, the detection space is divided into a plurality of interconnected wireless communication ranges, specifically, a central signal receiver is provided at the junction of the wireless communication ranges.

[0010] In a preferred embodiment, a plurality of signal receivers and a plurality of interference signal generators are arranged within the wireless communication range, specifically: a plurality of interference signal generators are subjected to periodic verification and detection, and the periodic verification and detection includes setting a periodic verification and detection period, and when the periodic verification and detection period is reached, the central processing unit controls the interference signal generator to work in a linear sequence to emit interference signals, and continues to emit interference signals after the last interference signal generator emits an interference signal; and determines whether the central processing unit controls the signal receiver at the corresponding position to be turned on according to the linear working sequence of the interference signal generator, and whether the interference source position located by the signal receiver is accurate.

[0011] In a preferred embodiment, the periodic verification and detection cycle is set as follows: the periodic verification and detection cycle is selected based on the number of interference signals that occur in a year. When the number of interference signals that occur in a year is greater than a preset threshold, the cycle is selected as a quarter; when the number of interference signals that occur in a year is less than the preset threshold, the cycle is selected as a year.

[0012] In a preferred embodiment, the position of the monitored interference signal is transmitted to the central processing unit, specifically: the interference source is limited in the central processing unit, the type of the interference source is determined, and after the central processing unit determines the interference source signal, the interference source is mapped and the emergency plan cannot be handled in time; the limitation of the interference source includes the following steps: setting an interference signal threshold, locating the interference source, and inferring the interference signal strength at the location where the interference source is emitted by reverse inference; when the interference signal strength emitted by the interference source is greater than the threshold, the central processing unit alarms and notifies relevant staff to handle it; when the interference signal strength emitted by the interference source is less than or equal to the threshold, the central processing unit ignores this signal interference source, and turns off the signal receivers except the signal receiver at the center of the wireless communication range, and records this interference source; the type of interference source judgment includes the following steps: establishing an interference signal information library, comparing the detected and located interference signal with the interference signal and interference frequency band contained in the interference signal information library; when the comparison result shows that this interference signal is not in the interference signal information When in the library, mark the interference signal as unknown, and wait for the processing personnel to report the source of the interference signal after processing; add the source of the interference signal to the interference signal information library; the mapping of the interference source includes the following steps: draw a plane map within the wireless communication range; mark all signal receivers on the plane map; coordinate the detected interference signal and highlight the coordinates on the plane map; mark each coordinate of the moving interference signal on the plane map, and connect each coordinate in chronological order; store the plane map; the plan that cannot be processed in time includes the following steps: detect the interference signal, and alarm to notify the processing personnel to continue processing; when the processing personnel arrive at the location of the interference source, no interference source is found, report this information, and highlight it on the plane map; record and save the interference source location of the interference signal, the interference frequency band and the interference signal strength; when the signal appears again, record the time difference between the two interference signals, and predict the time of the next appearance based on the time difference, and notify the processing personnel to arrive at the expected location of the interference source in advance to wait for the interference signal to appear in time.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, as Figure 1 As shown, the present invention provides a wireless communication interference detection method, comprising the following steps: Step S1, dividing the detection space into a plurality of interconnected wireless communication ranges; Step S2, setting a plurality of signal receivers and a plurality of interference signal generators within the wireless communication range, and connecting the plurality of signal receivers using a central processing unit; Step S3, setting one of the signal receivers within the wireless communication range to a normally open state, and locating the position of the interference signal by signal strength and time difference; Step S4, when the signal receiver receives the interference signal, it continuously monitors the interference signal, transmits the direction of the monitored interference signal to the central processing unit, and the central processing unit controls the signal receiver in the direction of the interference signal to start working; Step S5, the central processing unit continuously assigns other signal receivers in the direction of the interference signal to work successively, and turns off the signal receivers that are not in the moving direction, and continues to monitor until the interference signal disappears. Multiple signal receivers are arranged within the wireless communication range for detecting and locating interference signals; Multiple signal receivers are connected using a central processing unit to control the multiple signal receivers to be turned on or off. The central processing unit not only controls the signal receivers but also controls the interference signal generator, and the built-in processor is used to track and locate the interference signal and draw a graph; Take a signal receiver in the center of the wireless communication range and set it to the normally open state to monitor the interference signal in the wireless communication range in real time. The interference signal can be located by signal strength and time difference. Turning off the remaining signal receivers can reduce energy consumption and achieve energy-saving and environmental protection effects. When the signal receiver receives the interference signal, it continuously monitors the interference signal and transmits the location of the interference signal to the central processing unit; The central processing unit controls to start the signal receivers in the direction where the interference signal appears, and the number of signal receivers started is greater than or equal to two. Preferably, the number of signal receivers started is at least three, and accurate and rapid positioning is achieved through different positioning of the three signal receivers; If the interference signal is continuously monitored and it is found that the position of the interference signal has not changed, the interference signal is received and detected by the turned-on signal receiver, and the interference signal is continuously located by the detection strength and time difference of the interference signal detected by the turned-on signal receiver. A variety of positioning methods are used to comprehensively cover and calibrate the position of the interference signal to ensure its accuracy; If the interference signal is continuously monitored in the step and it is found that the position of the interference signal changes, the position variable is transmitted to the central processing unit through the signal receiver in the step, and the moving vector line of the interference signal during the continuous monitoring time is drawn by the central processing unit, and the next moving direction of the interference signal is predicted according to the moving direction of the moving vector line, and other signal receivers at the predicted moving direction are turned on; The central processing unit continuously assigns other signal receivers in the direction of movement of the interference signal to work successively, and shuts down signal receivers that are not in the moving direction; Continue monitoring until the interference signal disappears.

[0019] The interference signal is detected by the signal receiver at the center position, and the location of the interference signal is roughly judged. The central processing unit then turns on several signal receivers located closest to the interference source based on the result of this rough judgment to determine the location of the interference signal. The signal receivers that are turned on later are then used to continue to accurately locate the signal and feed it back to the central processing unit, which then implements dynamic tracking based on the location changes of the interference signal.

[0020] The signal receivers are arranged so that one signal receiver is arranged at the center of the wireless communication range, and the other signal receivers are arranged at the edges of the detection range of the signal receiver at the center, and the detection ranges of all signal receivers are superimposed together to completely cover the wireless communication range; It is used to ensure that the wireless communication detection range can be fully covered, and modular detection can be achieved through the cooperation of other blocks. The detection results of multiple blocks can be summarized and aggregated to detect the entire area, thereby increasing the detection range.

[0021] Wherein, in the area of ​​wireless communication range, a central signal receiver is arranged near the edge of the wireless communication range for connecting the wide range signal monitoring; To avoid a blind spot between two wireless communication ranges, a real-time signal receiver is used to connect two wireless communication range blocks that are not connected.

[0022] The relationship between signal strength and distance is as follows:

[0023] in, is the received power, is the transmit power, and are the gains of the transmitting and receiving antennas, respectively, is the wavelength, It is distance; The time difference positioning formula is:

[0024] in, It's time. It's distance. It is the speed of light; The signal attenuation model formula is:

[0025] in, is the received power, is the transmit power, is the attenuation coefficient, It is distance; The formula for the moving speed of the interference source is:

[0026] in, It's speed. is the distance change, is the time variation.

[0027] Among them, it also includes the limitation of interference sources, determination of the types of interference sources, mapping of the interference sources by the central processing unit after determining the interference source signals, and failure to deal with the emergency plan in a timely manner; Limiting interference sources includes the following steps: Establish an interference signal threshold. This threshold can be established according to the actual use environment, and the threshold can be regulated by the central processing unit; After locating the interference source, the interference signal strength at the location where the interference source is located is inferred by reverse engineering; When the interference signal strength from the interference source is greater than the threshold, the central processing unit will give an alarm and notify relevant staff to handle it; When the interference signal strength emitted by the interference source is less than or equal to the threshold, the central processing unit ignores the signal interference source, turns off the signal receivers except the signal receiver at the center of the wireless communication range, and records the interference source; By setting a threshold and utilizing the establishment of the threshold to reduce the sensitivity of the detection system, a method of only detecting weaker interference signals without alarming can be implemented. When the threshold is adjusted, the detected interference signals can be stored in the interference signal information library and used directly.

[0028] The determination of the type of interference source includes the following steps: Establish an interference signal information database; Compare the detected and located interference signal with the interference signal and interference frequency band contained in the interference signal information library; When the comparison result shows that the interference signal is not in the interference signal information database, the interference signal is marked as unknown, waiting for the processing personnel to process and report the source of the interference signal; Add the interference signal source to the interference signal information library.

[0029] By establishing an interference signal information database, it is possible to accurately determine the source of the interference signal and compare the frequency, time and intensity of the interference signal. This allows personnel who handle the interference signal to directly and conveniently find the source of the interference when they receive an alarm signal. There is no need for personnel to go to the location of the interference source and then search for it separately to determine what the interference source is.

[0030] Mapping the location of interference sources includes the following steps: Draw a flat map within the range of wireless communication; Mark all signal receivers on a flat map; The detected interference signal is coordinateized and the coordinates are highlighted on the plane map; Mark each coordinate of the moving interference signal on the flat map, and connect each coordinate in chronological order; Save this floor plan map; By drawing a plane map to mark the location of the interference signal, the interference signal can be processed in a planar manner, making it easier for the processing personnel to know the environment where the interference source is located more intuitively.

[0031] Among them, the signal strength and direction are combined to interfere with the moving direction of the predicted signal source. The formula is as follows:

[0032] in, and are the estimated distance and direction, It is The signal power received by each receiver is It is direction of the interference source.

[0033] Among them, the signal strength and time are combined to interfere with the moving direction of the predicted signal source. The formula is as follows:

[0034] in, and are the estimated distance and time, It is The signal power received by each receiver is It is The direction of the interference source, is the variance of time.

[0035] Among them, the signal strength and position are combined to interfere with the moving direction of the predicted signal source. The formula is as follows:

[0036] in, The estimated coordinate, It is The signal power received by each receiver is , ) is The coordinates of the signal receiver.

[0037] By setting up multiple signal receivers within the wireless communication range that needs to be detected, real-time detection is performed through the signal receiver located at the center of the detection range. When an interference signal appears, this signal receiver controls the operation of the signal receivers near the interference source through the central processing unit, and assigns different signal receivers to work in real time according to the movement of the interference source, so as to locate and predict the moving direction of the interference signal, and intercept the movement of the interference source in advance, which is the dynamic intelligent tracking of the interference signal.

[0038] In the second embodiment, three interference signal generators are set within the wireless communication range to emit interference signals according to the needs. The interference signal generators are used for regular verification and detection. The regular verification and detection method is as follows: Set up regular verification and testing cycles; When the periodic verification detection cycle is reached, the central processing unit controls the three interference signal generators to work in a linear numerical sequence to emit interference signals, and continues to emit interference signals after the last interference signal generator emits an interference signal; Determine whether the central processing unit controls the signal receivers at the corresponding positions to start according to the linear working order of the three interference signal generators, and whether the interference source position located by the signal receiver is accurate; By setting up three interference signal generators within the wireless communication range and using a periodic calibration method to turn on the three interference signal generators, a dynamic interference signal is presented within the wireless communication range to test whether the signal receiver can work normally and achieve the effect of automatic calibration.

[0039] Among them, the selection of the regular verification and detection cycle is based on the number of interference signals that occur within a year. When the number of interference signals that occur within a year is greater than twenty times, the cycle is selected as one month. When the number of interference signals that occur within a year is less than twenty times, the cycle is selected as one year.

[0040] By setting up a verification cycle based on the number of times the interference signal appears, the number of verifications can be reasonably arranged to avoid an increase in the workload of the processing personnel due to too many verifications, and to avoid a situation where the equipment is damaged and cannot be used normally due to too few verifications.

[0041] Among them, the emergency plan that cannot be handled in time includes the following steps: An interference signal is detected and an alarm is issued to notify the processing personnel to continue processing; When the processing personnel arrive at the location of the interference source, no interference source is found, and this information is reported, which is highlighted on the flat map; Record and save the interference source location of the interference signal, the interference frequency band and the interference signal strength; When this signal appears again, the time difference between the two interference signals is recorded, and the time of the next appearance is predicted based on the time difference. The processing personnel are notified to arrive at the expected location of the interference source in advance and wait for the interference signal to appear in time.

[0042] By establishing an emergency plan for situations where timely processing is not possible, when an interference signal that disappears for a short period of time appears, by recording information on the signal and making a comprehensive assessment of the situation, it is possible to predict the time and location of the next interference signal and to process the interference signal that disappears for a short period of time.
