- antenna feeder reversal is a common type of fault caused by hardware installation errors. This type of fault usually has a relatively large impact on network performance indicators, and it is generally not easy to troubleshoot.
- the existing automatic detection method of antenna feedback is mainly realized by calculating the correlation between the received signals of different antennas, such as using RTWP (Received Total Wideband Power) correlation or RSSI (Received Signal Strength Indication) , detect whether the antenna is reversed.
- RTWP Receiveived Total Wideband Power
- RSSI Receiveived Signal Strength Indication
- This type of automatic detection method essentially relies on the correlation coefficient threshold between the signals received by different antennas for detection, and if it exceeds the preset threshold, it is considered to be reversed.
- the embodiments of the present application provide an antenna feed reverse detection method, a model training method, an electronic device, and a computer-readable storage medium, which can improve the accuracy of antenna feed reverse detection.
- a base station 100 includes antennas, feeders, and sectors. Specifically, a base station 100 is usually provided with multiple sectors, and each sector is provided with at least two feeder ports 110. The antenna in charge of each sector is connected to the feeder port 110 of the corresponding sector through the feeder 120 to realize the pairing.
- the correct connection method of the antenna is: the two feeders 120 connected to the antenna 1 should be connected to the two feeder ports 110 of the sector 1 to form the signal coverage of the sector 1, and the antenna 2
- the two connected feeders 120 should be connected to the two feeder ports 110 of the sector 2 correspondingly to form the signal coverage of the sector 2.
- the solution provided by the embodiment of the present application is mainly used to detect whether the above two types of reverse connection problems exist in the antenna feeders 120 of all sectors under the same base station 100.
- an embodiment of the present application provides an antenna feed reverse detection method. Please refer to FIG. 2.
- the method includes but is not limited to the following steps:
- S1001 Obtain detection data of feeder ports of m sectors under the same base station, where m is an integer greater than 1, and generally, m represents the total number of sectors included in the base station.
- the detection data should include at least the first detection data.
- the first detection data may be RTWP data, where RTWP is the total broadband received power, which can reflect the power of the sector feeder port signal.
- the first detection data may be RSSI data, and the RSSI is a received signal strength indicator value, which can reflect the strength of the received signal at the sector feeder port.
- the first detection data may also be other data that can reflect the energy/intensity of the signal, and this application does not impose excessive restrictions on this.
- the detection data further includes second detection data, and the second detection data may specifically be balance count data.
- the number of balances reflects the degree of balance of the signal strength of any two feeder ports in the sector. Specifically, the energy received by these two feeder ports can be measured periodically to determine whether the energy difference between the two feeder ports is greater than the preset threshold. If yes, add one to the balance times of the feeder port with high energy; if not, add one to the balance times of the two feeder ports at the same time. The smaller the difference between the balance times of the two feeder ports, the more balanced the received signal strength of the two feeder ports, and vice versa, the more unbalanced the received signal strength.
- the detection data further includes third detection data, and the third detection data may specifically be MIMO activation ratio data.
- the MIMO activation ratio is the ratio of the time the user activates the MIMO to the total time the user occupies the service (the total time includes the time when MIMO is activated and the time when MIMO is not activated). It is only possible to activate MIMO when the user can receive the two signals from the same sector. In the case of reverse antenna feeder, the user generally can only receive one signal from the same sector, so it is difficult to activate MIMO, resulting in a relatively low proportion of MIMO activation.
- the aforementioned RTWP data, RSSI data, balance number data, and MIMO activation ratio data can all be directly obtained from the performance data output by the base station to the data center.
- S1003 Calculate the correlation coefficient of each port combination according to the first detection data, and select m port combinations from all the port combinations under connection conditions in descending order of the correlation coefficient, and select the elements of the m port combinations Disjoint each other.
- the correlation coefficient of each port combination is calculated. Specifically, for each possible combination, the correlation coefficients of any two ports in the combination can be calculated and summed.
- ⁇ (1,2,3,4) ⁇ (1,2)+ ⁇ (1,3)+ ⁇ (1,4)+ ⁇ (2,3)+ ⁇ (2,4)+ ⁇ (3, 4);
- the correlation coefficient of any two ports can be calculated by the following formula:
- the array X and the array Y refer to the first detection data of the two ports, for example, RSTW data or RSSI data.
- m port combinations are selected from all the port combinations under the connection conditions in order of correlation coefficients from large to small, and the elements of the selected m port combinations do not intersect each other, namely: In the process of selecting m port combinations from large to small according to the correlation coefficient, for each port combination selected, the elements contained in the currently selected port combination cannot be included in the previously selected port combination.
- the combination with the largest correlation coefficient is (1_1, 1_2, 1_3, 1_4), so this combination is selected as the first combination, and the combination with the second largest correlation coefficient is ( 1_1, 2_2, 2_3, 2_4), here because port 1_1 has appeared in the first combination above, the combination with the second largest correlation coefficient cannot be selected.
- m port combinations are selected in turn, and m ports The combined elements do not intersect each other.
- step S1004 Construct a first set according to the selected m port combinations. Based on the fact that these port combinations selected in step S1003 are selected in descending order of correlation coefficients, the high correlation of the port combinations indicates that the ports in the combination are likely to be connected to the same antenna device, so the first set is to a large extent Reflects the set of port combinations that are consistent with the current actual wiring situation, and subsequently can determine whether the antenna feeder is connected reversely according to the characteristics of the first set.
