Description

Technical Field

[0001] The present invention relates to the technical field of repeater operation and maintenance management, and specifically to a Beidou positioning repeater operation and maintenance management system based on 6G communication. Background Art

[0002] Repeater operation and maintenance management technology refers to the technology and methods for daily maintenance, monitoring and management of repeater equipment. A repeater is a device used to amplify wireless signals. It is mainly used to solve signal coverage problems, improve signal quality and communication effects. It is mainly used in mobile communication systems to enhance signal coverage, especially in areas with weak signals, such as mountainous areas and basements. Operation and maintenance management technology ensures the normal operation of these devices, extends the life of the equipment, and maintains signal quality.

[0003] Existing repeater operation and maintenance management technology usually monitors various working parameters in the repeater, and monitors whether various working parameters exceed preset thresholds by setting thresholds, so as to evaluate the health status of the repeater. However, this method relies too much on the preset thresholds, and the accuracy cannot be guaranteed. Different working parameters seem to be independent, but in fact there is a certain relationship. If different working parameters are unbalanced, at this time, although all working parameters are within the prescribed thresholds, in fact, the repeater has a slight fault, but the fault has not yet affected the working parameters, so it cannot be obtained through the threshold test. For example, in the Chinese patent application publication number CN115426669A, a remote maintenance method for a repeater is disclosed. This solution is to judge the health status of the repeater by comparing various thresholds, which relies too much on the preset thresholds, making it difficult to find potential faults of the repeater. The existing repeater operation and maintenance management technology still has the problem of relying too much on the preset thresholds in the application of fault management, making it difficult to find potential faults of the repeater. Summary of the invention

The advantage lies in that various debugging indicators of the Beidou positioning repeater are monitored in real time through preset thresholds to evaluate the health status of the Beidou positioning repeater. If any debugging indicator exceeds the threshold, it means that the Beidou positioning repeater fails. At this time, there is no need for further in-depth analysis, and judgment through thresholds is the most basic but indispensable part of fault analysis, improving the comprehensiveness and effectiveness of fault management in the operation and maintenance management of the Beidou positioning repeater.

[0059] The present invention comprehensively evaluates the debugging indicators, actual gain, and isolation threshold to obtain the indicator characteristics of the Beidou positioning repeater. At the same time, based on historical indicator characteristics, the range of indicator characteristics where the Beidou positioning repeater fails is analyzed and marked as the fault range. Finally, based on the fault range, it is determined in real time whether the Beidou positioning repeater has a fault. The advantage is that the indicator characteristics reflect the relationship between different debugging indicators, and the historical records record the different indicator characteristics of the Beidou positioning repeater under normal and faulty states. By analyzing historical characteristics, the distribution characteristics of faulty historical characteristics and normal historical characteristics can be known, and then the fault range can be found, so as to evaluate in real time whether the indicator characteristics of the Beidou positioning repeater are abnormal, improving the accuracy and rationality of fault management in the operation and maintenance management of the Beidou positioning repeater.

[0075] In practical applications, the debugging indexes include in-band flatness, input signal level, output signal level, and transceiver isolation degree, and the acquisition of the debugging indexes all adopts existing acquisition technologies. The in-band flatness is measured to be 2.68 dB, the input signal level is 4 dBm, the output signal level is 47.8 dBm, the calibrated gain is 45 dB, and the transceiver isolation degree is 61.2 dB; among them, dBm is the ratio of power to 1 milliwatt, that is, 10×lg(power / 1 milliwatt); in this embodiment, 6G communication is used for the transmission of the data self-signal to ensure the low latency of the operation and maintenance management.

[0076] The comprehensive evaluation module is used to comprehensively evaluate the debugging indicators and calculate the indicator characteristics of the Beidou positioning repeater; the comprehensive evaluation module includes an indicator processing unit, an initial evaluation unit, and a comprehensive evaluation unit;

[0080] Calculate the actual gain plus the first isolation value, and mark the calculation result as the isolation threshold;

[0081] In practical applications, the calculated actual gain is 43.8 dB, which means the output signal level is 43.8 dB greater than the input signal level; the first isolation value is set to 10 dB, and further calculation gives the isolation threshold of 53.8 dB; the setting of the first isolation value is a fixed value, and the requirement for the transceiver isolation is greater than or equal to the actual gain + 10 dB;

[0082] The initial evaluation unit is used to initially evaluate the debugging indicators, actual gain, and isolation threshold, and determine whether the Beidou positioning repeater has a fault;

[0083] The initial evaluation unit is configured with an initial evaluation strategy, and the initial evaluation strategy includes:

[0084] Obtain the flatness standard and gain error range;

[0085] Compare the in-band flatness with the flatness threshold. If the in-band flatness is less than the flatness threshold, output a flatness normal signal; if the in-band flatness is greater than or equal to the flatness threshold, output a flatness abnormal signal;

[0091] In practical applications, the obtained flatness standard is 3dB, and the gain error range is [-10%, 10%]. By comparison, the in-band flatness is less than the flatness threshold, and an output flatness normal signal is output; the calculated real-time gain error is (43.8 - 45) / 45×100% = -2.7%, and the calculation result is reserved to one decimal place. By looking up, the real-time gain error is within the gain error range, and a gain normal signal is output; by comparison, the transceiver isolation is greater than or equal to the isolation threshold, and an isolation normal signal is output; since the output flatness normal signal, the gain normal signal and the isolation normal signal are output, a comprehensive evaluation is performed on the debugging index, the actual gain and the isolation threshold; if any one of them outputs an abnormal signal, it means that there is a fault in the Beidou positioning repeater and maintenance is required in a timely manner;

[0096] The first index characteristic and the second index characteristic are collectively referred to as index characteristics;

[0097] In practical applications, the actual gain G is 43.8dB, the transceiver isolation R is 61.2dB. By calculation, the first index characteristic T1 is 0.72, and the calculation result is reserved to two decimal places. The in-band flatness P1 is 2.68dB, and the flatness threshold P2 is 3dB. By calculation, the second index characteristic T2 is 0.89, and the calculation result is reserved to two decimal places; calculating the first index characteristic from the actual gain and the transceiver isolation is because there is a certain relationship between the actual gain and the transceiver isolation, and the requirement for the transceiver isolation is greater than or equal to the actual gain + 10dB.

Based on the normal feature line, the normal left boundary X is obtained as 0.5, the normal left boundary Y is obtained as 0.56, the normal right boundary X is obtained as 0.85, and the normal right boundary Y is obtained as 0.88; based on the fault feature line, the fault left boundary X is obtained as 0.5, the fault left boundary Y is obtained as 0.38, the fault right boundary X is obtained as 0.86, and the fault right boundary Y is obtained as 0.75;

[0118] Please refer to Figure 4 shown. Connect the first separation point and the second separation point with a straight line and extend both ends of the straight line infinitely, dividing the feature distribution diagram into two regions. Among them, the region containing the normal feature line is named the normal range, and the region containing the fault feature line is named the fault range;

[0119] In practical applications, it is further calculated that the separation left boundary X is 0.5, the separation left boundary Y is 0.47, the separation right boundary X is 0.855, and the separation right boundary Y is 0.815; the first separation point is obtained as (0.5, 0.47), and the second separation point is obtained as (0.855, 0.815); the normal range and the fault range are divided as Figure 4As shown in the figure, the dashed line is the straight line obtained by connecting and extending the first separation point and the second separation point. In the first quadrant of the coordinate system, the area located below the dashed line and the dashed line is the fault range, and the area located above the dashed line is the normal range.

[0120] The operation and maintenance evaluation module is used to judge in real time whether there is a fault in the Beidou positioning repeater based on the fault range;

[0121] The operation and maintenance evaluation module is configured with an operation and maintenance evaluation strategy, and the operation and maintenance evaluation strategy includes:

[0122] Name the coordinate points corresponding to the normal historical features as normal coordinate points, and name the coordinate points corresponding to the fault historical features as fault coordinate points;

[0123] Count the number of fault coordinate points and the number of normal coordinate points in the fault area, and name them as the normal quantity and the fault quantity respectively. Calculate the quotient of the normal quantity divided by the fault quantity to obtain the error ratio;

[0124] Monitor and calculate the index features of the Beidou positioning repeater in real time, and name the corresponding coordinate points as monitoring coordinate points;

[0125] Taking the first period as an evaluation period, count the number of monitoring coordinate points obtained within the evaluation period that are in the normal range and the fault range, and name them as the first quantity and the second quantity respectively;

[0126] In practical applications, Figure 2 the normal historical features in are the normal coordinate points, and the fault historical features are the fault coordinate points; the normal quantity and the fault quantity are statistically obtained as 27 and 169 respectively, and the calculated error ratio is 16.0%. The calculation result is retained to one decimal place in percentage form; the setting of the first period is to prevent the judgment result from being incorrect due to accidental factors during single monitoring. By continuously monitoring in the first period and obtaining multiple data for fault analysis, the influence of accidental factors can be excluded; in this embodiment, the first period is set to 30s, and the Beidou positioning repeater in this embodiment collects and adjusts the index every 2s. Therefore, 15 data will be generated in 30s. Through analysis, among these 15 data, 2 data are in the normal range and 13 data are in the fault range, that is, the first quantity is 2 and the second quantity is 13;

[0127] Calculate the quotient of the first quantity divided by the second quantity, and mark the calculation result as the period index;

[0128] Compare the period index with the error ratio. If the period index is less than or equal to the error ratio, output a status fault signal; if the period index is greater than the error ratio, output a status normal signal;

[0129] If a status fault signal is output, send a maintenance message to the maintenance end;

[0130] In practical applications, the calculated cycle index is 2 / 13×100% = 15.4%. The calculation result is rounded to one decimal place. By comparison, the cycle index is less than the error ratio, and a status fault signal is output, and a maintenance message is sent to the maintenance end; the error ratio represents a 16% probability of incorrect judgment. During actual detection, when the cycle index is less than or equal to the error ratio, it means the judgment result is accurate, and when the cycle index is greater than the error ratio, it means the detection result may have an error. At this time, the judgment of the next cycle is required.

The electronic device may include: a processor, a communication interface, a memory, and a communication bus. Among them, the processor, the communication interface, and the memory complete mutual communication through the communication bus. The memory stores computer-readable instructions, and the processor can call the instructions in the memory. When the computer-readable instructions are executed by the processor, the policies in the Beidou positioning repeater operation and maintenance management system based on 6G communication are run to achieve the following functions: monitoring the debugging indicators of the Beidou positioning repeater; comprehensively evaluating the debugging indicators, and calculating the indicator characteristics of the Beidou positioning repeater; analyzing the range of the indicator characteristics of the Beidou positioning repeater that fails based on historical indicator characteristics, and marking it as the fault range; and judging in real time whether the Beidou positioning repeater has a fault based on the fault range.

[0132] In addition, when the logical instructions in the above-mentioned memory are implemented in the form of software functional units and sold or used as an independent product, they can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or this part of the technical solution, can be embodied in the form of a software product.
