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

[0004] The present invention aims to solve one of the technical problems in the prior art to at least a certain extent, by monitoring the debugging index of a Beidou positioning repeater, calculating the actual gain and isolation threshold of the Beidou positioning repeater, and then performing an initial evaluation on the debugging index, the actual gain and the isolation threshold to determine whether the Beidou positioning repeater has a fault, and then performing a comprehensive evaluation on the debugging index, the actual gain and the isolation threshold to obtain the index characteristics of the Beidou positioning repeater, and at the same time analyzing the range of the index characteristics of the Beidou positioning repeater having a fault based on historical index characteristics, marking it as a fault range, and finally determining in real time based on the fault range whether the Beidou positioning repeater has a fault, so as to solve the problem that the existing repeater operation and maintenance management technology still relies too much on a preset threshold in the application of fault management, resulting in difficulty in discovering potential faults of the repeater.

The advantage is that various debugging indexes of the Beidou positioning repeater are monitored in real time through preset thresholds to determine whether they are abnormal, so as to evaluate the health status of the Beidou positioning repeater. If any debugging index exceeds the threshold, it means that the Beidou positioning repeater fails. In this case, no in-depth analysis is required. Threshold judgment is the most basic but indispensable part of fault analysis, which improves the comprehensiveness and effectiveness of fault management in the operation and maintenance management of the Beidou positioning repeater.

[0059] The present invention obtains the index characteristics of the Beidou positioning repeater by comprehensively evaluating the debugging index, the actual gain and the isolation threshold, and analyzes the range of the index characteristics of the Beidou positioning repeater fault based on the historical index characteristics, marking it as the fault range, and finally judges in real time whether the Beidou positioning repeater has a fault based on the fault range. The invention has the advantages that the index characteristics reflect the relationship between different debugging indexes, and the different index characteristics of the Beidou positioning repeater in a normal state and a fault state are recorded in the historical records. The distribution characteristics of the fault historical characteristics and the normal historical characteristics can be known by analyzing the historical characteristics, and the fault range is then found out, so as to evaluate in real time whether the index characteristics of the Beidou positioning repeater are abnormal, thereby improving the accuracy and rationality of fault management in the operation and maintenance management of the Beidou positioning repeater.

[0118] See also Figure 4 As shown, the first dividing point and the second dividing point are connected by a straight line, and both ends of the straight line are infinitely extended to divide the characteristic distribution diagram into two areas, wherein the area containing the normal characteristic straight line is named the normal range, and the area containing the fault characteristic straight line is named the fault range;

In the first quadrant of the coordinate system, the area located at and below the dotted line is the fault range, and the area located above the dotted line is the normal range.

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

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

[0122] The coordinate points corresponding to normal historical features are named normal coordinate points, and the coordinate points corresponding to fault historical features are named fault coordinate points;

[0123] Count the number of fault coordinate points and the number of normal coordinate points in the fault area, name them normal number and fault number respectively, divide the normal number by the fault number to get the error ratio;

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

[0125] Taking the first cycle as an evaluation cycle, the number of monitoring coordinate points in the normal range and the number of fault ranges obtained in the evaluation cycle are counted, and are named as the first number and the second number respectively;

[0126] In practical applications, Figure 2 The normal historical features in the data are normal coordinate points, and the fault historical features are fault coordinate points; the normal number and the fault number are 27 and 169 respectively, and the error ratio is calculated to be 16.0%, and the calculation result is expressed as a percentage with one decimal place; the first cycle is set to prevent the judgment result from being wrong due to accidental factors during a single monitoring. By continuously monitoring the first cycle and obtaining multiple data for fault analysis, the influence of accidental factors can be eliminated; in this embodiment, the first cycle is set to 30s, and the Beidou positioning repeater in this embodiment collects data every 2s to control the index, so 15 data will be generated in 30s. Through analysis, it is found that among the 15 data, 2 data are in the normal range and 13 data are in the fault range, that is, the first number is 2 and the second number is 13;

[0127] Calculate the first quantity divided by the second quantity and mark the result as the periodic indicator;

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

[0129] If the output status is a fault signal, the maintenance information is sent to the maintenance terminal;

[0130] In actual applications, the cycle index is calculated to be 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 maintenance information is sent to the maintenance end. The error ratio represents a 16% probability of misjudgment. In actual detection, if the cycle index is less than or equal to the error ratio, it means that the judgment result is accurate. If the cycle index is greater than the error ratio, it means that there may be errors in the detection result, and the judgment of the next cycle needs to be performed.
