Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0023] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0024] During the installation of antennas at mobile communication sites, the feeder of the antenna (or RF feeder) may be connected reversely due to negligence of the construction party. Feeder connection reverse means that the two wires in the feeder installed on the antenna are swapped or connected incorrectly. This incorrect connection may cause the performance of the wireless communication system to degrade, or even cause the wireless communication system to fail to work properly, seriously affecting the communication quality of the wireless communication system.

[0025] Therefore, it is particularly important to detect and troubleshoot the reverse connection of the antenna feeder to improve the communication quality of the wireless communication system.

[0026] In order to solve this technical problem, an embodiment of the present application provides a method, device, terminal device and storage medium for detecting reverse connection of an antenna feeder line, wherein the method for detecting reverse connection of an antenna feeder line is applied to a terminal device, which includes but is not limited to a network management device.

[0027] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] See also Figure 1 , Figure 1 A schematic diagram of the system structure of a network element management system provided in an embodiment of the present application.

[0029] like Figure 1As shown, the network element management system 100 includes a network element device 20 and a terminal device 10 that is communicatively connected to the network element device 20, wherein the network element device 20 includes but is not limited to a base station and a repeater. The terminal device 10 may be a network management device for managing the network element device 20. Usually, a plurality of network element devices 20 are arranged in a grid cell 30. The terminal device 10 is communicatively connected to the network element devices 20 in each area to realize monitoring or management of the network element device 20.

[0030] For example, taking the network element device 20 as a base station, one or more base stations are usually deployed in a grid cell 30 to provide communication services for the grid cell 30. The user obtains attribute-related data of the base station through the terminal device 10, wherein the attribute-related data includes but is not limited to communication performance, hardware information, location information, and identity information. The terminal device 10 can analyze whether there is an abnormality in the current base station through the attribute-related data of the base station. For example, by obtaining the attribute-related data of the base station, it can be analyzed whether there is an abnormality in the reverse connection of the feeder of the antenna set at the base station.

[0031] See also Figure 2 , Figure 2 A flowchart of the steps of a method for detecting reverse connection of an antenna feeder provided in an embodiment of the present application.

[0032] like Figure 2 As shown, the reverse connection detection method of the antenna feeder is applied to the terminal device 10, and the reverse connection detection method of the antenna feeder includes steps S101 to S103.

[0033] Step S101: Determine each antenna port corresponding to the target object, and obtain the signal reception strength of each antenna port.

[0034] Exemplarily, the target object may be a grid cell selected from multiple grid cells 30 to be checked, or may be the network element device 20. In the embodiment of the present application, the target object is a grid cell 30 as an example for description, but the target object is not limited to only the grid cell 30.

[0035] The grid cell 30 is provided with one or more network element devices 20, and the network element device 20 is provided with one or antenna modules, and each antenna module corresponds to an antenna receiving port. Usually, the signal coverage direction and signal coverage range of the antenna receiving ports corresponding to different antenna modules in the grid cell 30 are roughly the same, that is, the uplink background noise and useful signal received by each antenna module are also basically the same. Although the signal attenuation of each antenna module may be different, the signal attenuation is usually a fixed value. Therefore, the signal reception strength of multiple antenna modules of one or more network element devices 20 in a grid cell 30 should have a strong linear correlation.

[0036] When the feeder line of the antenna module is connected reversely, the signal reception strength of the antenna module is affected. Therefore, by obtaining the signal reception strength of multiple antenna modules in the same grid cell 30, it is possible to analyze whether there is an antenna module with abnormal signal reception in the current grid cell, and then it is possible to analyze whether the antenna module has the feeder line connected reversely.

[0037] Therefore, before determining whether the feeder line of the antenna module in the grid cell 30 is connected reversely, the signal reception strength of each antenna port corresponding to the antenna module of each base station set in the grid cell 30 is first obtained, and then a linear correlation analysis is performed on the signal reception strength of each antenna port, so as to determine whether the feeder line of the antenna module in the grid cell 30 is connected reversely.

[0038] In some implementations, determining each antenna port corresponding to the target object and obtaining the signal reception strength of each antenna port includes:

[0039] Extracting preset base station related data from a database according to a data extraction instruction;

[0040] A target object to be detected is determined, and each antenna port adapted to the target object is determined from the base station related data, and a signal receiving strength corresponding to each antenna port is obtained.

[0041] Exemplarily, taking the target object as the grid cell 30 as an example, the terminal device 10 receives a data extraction instruction and extracts base station related data from the database according to the data processing instruction. The base station related data includes but is not limited to the signal reception strength of the antenna port corresponding to the antenna module of each base station, the identity information of the base station, and the mapping relationship information between the base station and the antenna port.

[0042] At the same time, the grid cell 30 to be detected is determined according to the selection instruction, and each antenna port adapted to the grid cell 30 is determined from the base station related data, and the signal reception strength corresponding to each antenna port in the grid cell 30 is obtained.

[0043] For example, if N base stations are installed in the grid cell 30, the preset base station related data is extracted from the database according to the data extraction instruction, and after the grid cell 30 to be detected is determined, the N base station information in the grid cell 30 is screened out according to the base station related data, and the port information corresponding to the antenna port adapted by the antenna module on each base station is determined according to the base station information, and the signal receiving strength of each corresponding port information is obtained. That is, according to the corresponding instruction, the signal receiving strength of the antenna port corresponding to the antenna module installed on all base stations in the grid cell 30 is obtained.

[0044] In some implementations, the data extraction instruction is an instruction generated when a preset option in the display interface of the terminal device is triggered by an external object.

[0045] Exemplarily, the terminal device 10 displays a data extraction interface in which a plurality of preset options are provided. The corresponding option is selected through the input device to generate the corresponding data extraction instruction, so that the terminal device 10 extracts the preset base station related data from the database according to the data extraction instruction.

[0046] Step S102: Calculate the correlation coefficient matrix of the signal reception strength of each antenna port using a preset function.

[0047] Exemplarily, the relative relationship between the signal reception strengths of each antenna port is described by a correlation coefficient matrix to analyze the linearity between the signal reception strengths of each antenna port, thereby analyzing whether there is an abnormality in the signal reception strength of each antenna port based on the linearity.

[0048] In some implementations, the calculating the correlation coefficient matrix of the signal reception strength of each of the antenna ports by using a preset function includes:

[0049] The signal reception strengths of the antenna ports are sorted according to the time sequence, and a correlation coefficient matrix of the signal reception strengths of the antenna ports after sorting is calculated using a preset function.

[0050] Optionally, the preset function includes at least one of a Numpy library function and a Corr function.

[0051] Exemplarily, after obtaining the signal reception strength of the antenna port corresponding to the antenna module of each base station in the grid cell 30 to be checked, the signal reception strength is sorted in the chronological order of signal reception. After the sorting is completed, the correlation coefficient matrix of the signal reception strength of each antenna port is calculated by the Numpy library function or the Corr function. The correlation coefficient matrix can be used to analyze the signal reception strength of each antenna module, so as to determine whether there is an abnormality in the signal reception strength corresponding to each antenna port, and then determine whether the antenna module of the base station installed in the grid cell 30 has the antenna feeder connected reversely.

[0052] Step S103: judging whether the target object has an antenna feed line connected in reverse according to the correlation coefficient matrix.

[0053] Exemplarily, if the signal reception strength corresponding to each antenna port of the grid cell 30 forms a certain linear rule, then each matrix element of the correlation coefficient matrix is ​​greater than or equal to a preset value, that is, it indicates that the grid cell does not have a reverse connection of the antenna feeder. If the linear rule of the signal reception strength corresponding to each antenna port of the grid cell 30 is abnormal, then any matrix element of the correlation coefficient matrix is ​​less than a preset value, that is, it indicates that the grid cell 30 may have a reverse connection of the antenna feeder and maintenance is required.

[0054] In some implementations, determining whether the target object has an antenna feed line connected reversely according to the correlation coefficient matrix includes:

[0055] Obtain each matrix element corresponding to the correlation coefficient matrix, and obtain the minimum value of the matrix elements, wherein the matrix elements are in the correlation coefficient matrix;

[0056] It is determined whether the antenna feed line of the target object is connected reversely according to the minimum value of the element.

[0057] Optionally, judging whether the target object has an antenna feeder connected reversely according to the minimum value of the element includes:

[0058] When the minimum value of the element is less than a preset value, it is determined that the antenna feed line of the target object is connected reversely;

[0059] When the minimum value of the element is greater than or equal to a preset value, it is determined that the target object does not have an antenna feed line connected in reverse.

[0060] Exemplarily, after obtaining the correlation coefficient matrix, if the minimum value of each matrix element in the correlation coefficient matrix is ​​greater than or equal to the preset value, it indicates that the correlation of all pairwise combinations of the signal reception strength of each antenna port is greater than or equal to the preset value, which means that it is determined that there is no problem of reverse connection of the antenna feeder line in this grid cell.

[0061] If the elements of each matrix element in the correlation coefficient matrix are less than the preset value, the correlation of any two combinations of the signal reception strength of each antenna port is greater than the preset value and less than the preset value, that is, it is determined that there is a problem of reverse connection of the antenna feeder line in this grid cell.

[0062] See also Figure 3, the embodiment of the present application also provides a reverse connection detection device 200 for an antenna feeder, wherein the reverse connection detection device 200 for an antenna feeder includes an information processing module 201, a matrix analysis module 202 and a reverse connection judgment module 203. The information processing module 201 is used to determine each antenna port corresponding to the target object and obtain the signal reception strength of each of the antenna ports. The matrix analysis module 202 is used to calculate the correlation coefficient matrix of the signal reception strength of each of the antenna ports using a preset function. The reverse connection judgment module 203 is used to judge whether the antenna feeder of the target object is reversely connected according to the correlation coefficient matrix.

[0063] In some implementations, determining each antenna port corresponding to the target object and obtaining the signal reception strength of each antenna port includes:

[0064] Extracting preset base station related data from a database according to a data extraction instruction;

[0065] A target object to be detected is determined, and each antenna port adapted to the target object is determined from the base station related data, and a signal receiving strength corresponding to each antenna port is obtained.

[0066] In some implementations, the data extraction instruction is an instruction generated when a preset option in the display interface of the terminal device is triggered by an external object.

[0067] In some implementations, the calculating the correlation coefficient matrix of the signal reception strength of each of the antenna ports by using a preset function includes:

[0068] The signal reception strengths of the antenna ports are sorted according to the time sequence, and a correlation coefficient matrix of the signal reception strengths of the antenna ports after sorting is calculated using a preset function.

[0069] In some embodiments, the preset function includes at least one of a Numpy library function and a Corr function.

[0070] In some implementations, determining whether the target object has an antenna feed line connected reversely according to the correlation coefficient matrix includes:

[0071] Obtain each matrix element corresponding to the correlation coefficient matrix, and obtain the minimum value of the matrix elements, wherein the matrix elements are in the correlation coefficient matrix;

[0072] It is determined whether the antenna feed line of the target object is connected reversely according to the minimum value of the element.

[0073] In some implementations, judging whether the target object has an antenna feed line connected reversely according to the minimum value of the element includes:

[0074] When the minimum value of the element is less than a preset value, it is determined that the antenna feed line of the target object is connected reversely;

[0075] When the minimum value of the element is greater than or equal to a preset value, it is determined that the target object does not have an antenna feed line connected in reverse.

[0076] It can be understood that the antenna feeder reverse connection detection device 200 can be applied to the terminal device 10. For example, the network element device upgrade device 200 is integrated in the terminal device 10, or is independently set relative to the terminal device 10 and communicated with the terminal device 10.
