Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to a method, apparatus, device, and readable storage medium for monitoring the downtilt angle of a base station antenna. Background Art

[0002] With the rapid development of mobile communication technology, telecom operators are deploying a large number of mobile communication base stations to better develop mobile communication services. The downtilt angle of base station antennas has a significant impact on their coverage range and network interference. Accurate downtilt angle of base station antennas ensures that the actual coverage range of the base station is consistent with the intended coverage range.

[0003] However, with the development of cities and market economy, super high-rise buildings may be built in cities and become city landmarks. Due to their large size and width, buildings will have a certain blocking and interference effect on base station antenna signals, causing the buildings to block part of the signal, making it impossible for users at the edge of the base station antenna coverage to access. Therefore, there is an urgent need for a base station antenna downtilt angle monitoring method that can predict, monitor and adjust the base station antenna downtilt angle. Summary of the Invention

[0014] If the coverage height of the new building location is less than or equal to the planned height of the new building, the new building will interfere with the signal of the current monitoring area;

[0015] If the coverage height of the new building location is greater than the planned height of the new building, the new building does not cause signal interference to the current monitoring area.

[0026] This reduces the interference of new buildings on the edge areas of the current monitoring area near the new buildings, and reduces the impact of base station antenna coverage on user reception signals at the edge of the base station antenna coverage.

[0035] If the current base station antenna downtilt angle is within the preset range, the current base station antenna downtilt angle data is recorded;

[0036] If the current base station antenna downtilt angle is not within a preset specified range, the current base station antenna downtilt angle is verified.

[0037] By adopting the above technical solution, a tilt sensor is used to monitor the mechanical downtilt angle of the base station antenna. When the downtilt angle is inaccurate, the downtilt angle of the base station antenna is adjusted in a timely manner to reduce the impact of inaccurate signal coverage caused by the inaccurate downtilt angle.

[0064] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0065] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0066] An embodiment of the present application provides a method for monitoring the downtilt angle of a base station antenna. The method for monitoring the downtilt angle of a base station antenna can be executed by an electronic device. The electronic device can be a server or a mobile terminal device. The server can be an independent physical server, a service cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The mobile terminal device can be a tablet computer, a mobile phone, a desktop computer, etc., but is not limited to this.

[0067] The following is a further detailed description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 As shown, the main flow chart of the method is described as follows (steps S101 to S104):

[0068] Step S101, pre-dividing at least one monitoring area according to the location of the base station antenna;

[0069] In the implementation mode of the present application, a base station is set up in each monitoring area. Since two electromagnetic waves of the same frequency will superimpose or cancel each other, that is, co-frequency interference, the base station antenna frequencies of each pair of adjacent base stations are different; the area size of the monitoring area can be divided according to the number of antennas of the base station, the height, azimuth, antenna downtilt angle of each antenna in the base station and the user density in the monitoring area.

[0070] Base station antenna downtilt includes mechanical downtilt and electrical downtilt. Mechanical downtilt is achieved by adjusting the mounting bracket and changing the physical position of the antenna, allowing for continuous adjustment of the downtilt angle. Electrical downtilt uses several key antenna phase shifters to continuously adjust the antenna feed network, continuously changing the phase of each oscillator in the antenna array. This allows for continuous adjustment of the antenna downtilt angle while maintaining the physical position of the antenna. When setting up base station antennas in a monitoring area, the height of the base station antenna should remain roughly consistent within the coverage area and should not be too high to avoid cross-area coverage. The antenna's main lobe direction should also be unobstructed. The effective coverage range of the base station should be fully considered to ensure that the system meets the coverage requirements. Mechanical downtilt and electrical downtilt are typically used in combination. Mechanical downtilt is set between 1 and 5 degrees, with the remainder supplemented by electronic downtilt.

[0071] Step S102: For any of the monitoring areas, obtain new construction project information within the monitoring area; the new construction project information includes information such as the planned location of the new building, the planned area of the new building, the planned height of the new building, and the planned material information of the new building;

[0072] In the embodiments of this application, a front-end database access method can be used to connect the front-end database with municipal systems, building systems, and other systems related to new buildings to monitor building information. When new construction project information is available, the front-end database pushes the new construction project information to the electronic device, which receives the new construction project information and determines the monitoring area where the new building is located. Alternatively, a new construction project information filling method can be used, where the user logs into the electronic device's reporting system and creates a new construction information form to report the new construction project information data.

[0073] Step S103, obtaining base station antenna information in the current monitoring area and adjacent monitoring areas; the base station antenna information includes information such as the base station location, the number of antennas in the base station, the base station antenna height of each base station antenna, the base station antenna azimuth, the base station antenna downtilt angle, and the base station antenna frequency;

[0074] In an embodiment of the present application, the base station antenna information of each area is pre-stored in the electronic device according to the area label. When there is a new building or signal interference in any monitoring area, the area is recorded as the current monitoring area, and the surrounding monitoring areas are recorded as adjacent monitoring areas. The electronic device retrieves the base station antenna information of the current monitoring area and the base station antenna information of the adjacent monitoring area based on the area label of the current monitoring area and the area label of the adjacent monitoring area.

[0075] Step S104, determining whether the newly built building interferes with the signal in the current monitoring area;

[0076] Furthermore, step S104 specifically includes: the electronic device calculates the coverage height of the planned location of the new building based on the base station antenna information of the current monitoring area, the new construction information and a preset downtilt angle calculation formula; the preset downtilt angle calculation formula is: Where α is the downtilt angle of the base station antenna, H is the effective height of the base station antenna, β is the vertical half-power angle of the base station antenna, and R is the coverage distance;

[0077] like Figure 2 As shown in (a), if the coverage height of the new building location is less than or equal to the planned height of the new building, the new building will interfere with the signal of the current monitoring area, and the new building will block the users at the edge of the base station antenna coverage from receiving and accessing the signal.

[0078] like Figure 2 As shown in (b), if the coverage height of the new building location is greater than the planned height of the new building, the new building will not cause signal interference to the current monitoring area, and the new building will have little impact on the reception and access signals of users at the edge of the base station antenna coverage.

[0079] Step S105: If the newly built building interferes with the signal in the current monitoring area, a base station antenna adjustment report is generated based on the newly built construction information and the base station antenna information.

[0080] Specifically, step S105 includes the following sub-steps (steps S1051 to S1058) (not shown in the figure):

[0081] Step S1051, calculating the base station antenna adjustment height and / or base station antenna adjustment angle of the current monitoring area based on the base station antenna information and the new construction project information of the current monitoring area to obtain a first adjustment plan;

[0082] By adjusting the height and / or angle of the base station antenna relative to the newly built building in the current monitoring area, the base station antenna can cover the newly built building, reducing the interference of the newly built building on the edge of the current monitoring area near the newly built building, thereby reducing the impact of the base station antenna on the reception of signals by users at the edge of the coverage area.

[0083] Step S1052: Calculate the base station antenna adjustment height and / or base station antenna adjustment angle of the adjacent area based on the base station antenna information and the new construction project information of the adjacent area to obtain a second adjustment solution;

[0084] By adjusting the height and / or relative orientation of the base station antenna in the adjacent monitoring area to the newly built building, the adjacent base station antenna can cover the interference area in the current monitoring area, change the antenna frequency of the interference area, reduce the interference of the newly built building on the edge area of the current monitoring area close to the newly built building, and thus reduce the impact of the base station antenna coverage on the reception of signals by users at the edge of the new building.

[0085] Step S1053, obtaining map information of the current monitoring area;

[0086] Step S1054, selecting a base station location of a newly added base station based on the map information, base station antenna information of the current monitoring area, base station antenna information of adjacent areas, and new construction project information;

[0087] Step S1055: determining the effective height, downtilt angle, and azimuth of the base station antenna of the newly added base station based on the base station location, planned coverage, and preset antenna setting rules of the newly added base station;

[0088] In the embodiment of the present application, for example, when the antenna downtilt angle is 10 degrees and the antenna is 5 meters away from the building surface, the height of the antenna above the building shall not be less than 2.1 meters; when the antenna downtilt angle is 20 degrees and the antenna is 30 meters away from the building surface, the height of the antenna above the building shall not be less than 15.6 meters.

[0089] Step S1056: Determine the base station antenna frequency of the newly added base station based on the base station antenna frequency of the current monitoring area and the base station antenna frequencies of the adjacent base stations; the base station antenna frequency of the newly added base station is different from the base station antenna frequencies of the current monitoring area and the adjacent monitoring areas;

[0090] Step S1057: Obtain a third adjustment solution based on the base station location, base station antenna effective height, base station antenna downtilt angle, base station antenna azimuth, and base station antenna frequency of the newly added base station;

[0091] By adding new base stations, the antennas of the new base stations can cover the interference areas in the current monitoring area, and the antenna frequencies of the new base station antennas do not interfere with the frequencies of the base station antennas in the current monitoring area and the adjacent monitoring areas. By adding new base station antennas, the interference of new buildings on the edge areas of the current monitoring area close to the new buildings is reduced, thereby reducing the impact of the base station antenna coverage on the reception of signals by users at the edge of the receiving area.

[0092] Step S1058: Generate a base station antenna adjustment report based on the first adjustment plan, the second adjustment plan, and the third adjustment plan. Integrating the first adjustment plan, the second adjustment plan, and the third adjustment plan into the base station antenna adjustment report facilitates user reference and facilitates user selection of an adjustment plan based on actual conditions.

[0093] Furthermore, step S1058 specifically includes: pre-establishing an antenna three-dimensional model regarding the base station antenna information and the monitoring area; in the embodiment of the present application, the three-dimensional model displays basic information such as the coverage range, number of base station antennas, azimuth, and downtilt angle of the base station antenna;

[0094] The electronic device obtains the three-dimensional antenna models of the current monitoring area and the adjacent monitoring areas;

[0095] Based on the new construction project information, a three-dimensional image of the new building is drawn in the three-dimensional model to obtain an antenna monitoring image; the new building is drawn in the three-dimensional image using simple geometric bodies, so that the user can intuitively see the position relationship, interference relationship, etc. of the new building and the base station antennas in the current monitoring area and adjacent monitoring areas.

[0096] The first adjustment scheme, the second adjustment scheme, and the third adjustment scheme are marked in the antenna monitoring image, and a base station antenna adjustment report is generated.

[0097] In an embodiment of the present application, the adjusted height of the base station antenna in the current monitoring area is drawn in the antenna monitoring image according to the first adjustment scheme, and the first adjustment scheme is marked at the corresponding position to generate a first adjustment report; the adjusted height of the base station antenna in the adjacent monitoring area is drawn in the antenna monitoring image according to the second adjustment scheme, and the second adjustment scheme is marked at the corresponding position to generate a second adjustment report; the base station position, effective height of the base station antenna, downtilt angle of the base station antenna, etc. of the newly added base station are drawn in the antenna monitoring image according to the third adjustment scheme, and the third adjustment scheme is marked at the corresponding position to generate a third adjustment report; the first adjustment report, the second adjustment report and the third adjustment report are merged to obtain a base station antenna adjustment report.

[0098] By generating a visual base station antenna adjustment report from the adjustment plan for users to view, it is convenient for users to select adjustment plans. In addition, by obtaining new construction information and predicting the interference impact of new construction information on the monitoring area, users can adjust the base station antenna in time according to the base station adjustment report, thereby reducing the interference of new buildings on the edge areas of the current monitoring area near the new buildings.

[0099] Since the mechanical tilt angle of the base station antenna may be affected by factors such as the environment and external forces, resulting in inaccurate mechanical downtilt angle, as an optional implementation of the embodiment of the present application, Figure 3As shown, before obtaining the base station antenna information in the current monitoring area and the adjacent monitoring areas, the process further includes (steps Sa to Sb):

[0100] Step Sa, obtaining the current base station antenna downtilt data collected by the tilt sensor;

[0101] In an embodiment of the present application, a tilt sensor is installed on each base station antenna. The tilt sensor collects the mechanical downtilt angle of the base station antenna, and the tilt sensor sends the collected data to the electronic device in real time. After the electronic device obtains the downtilt angle data of the base station antenna, the downtilt angle data of the base station antenna is stored. Cloud storage can be used, and the downtilt angle data of the base station antenna can also be stored locally.

[0102] Step Sb: Determine whether the current base station antenna downtilt angle is within a preset range based on historical base station antenna downtilt angle data within a preset time interval and a preset downtilt angle range; if the current base station antenna downtilt angle is within the preset range, record the current base station antenna downtilt angle data; if the current base station antenna downtilt angle is not within the preset range, verify the current base station antenna downtilt angle. If the base station antenna downtilt angle is inaccurate, adjust the base station antenna downtilt angle to reduce the signal coverage affected by the inaccurate base station antenna downtilt angle.

[0103] Specifically, the verifying the current base station antenna downtilt angle includes:

[0104] The electronic device obtains the current base station antenna image data collected by the drone; the current base station image data is collected by the drone while flying around the base station;

[0105] The electronic device then determines whether the downtilt angle of the current base station needs to be adjusted based on the current base station antenna image data;

[0106] In an embodiment of the present application, the electronic device converts the current base station antenna image into a grayscale image; then binarizes the grayscale image, and segments the antenna and the background image through an adaptive segmentation algorithm based on the difference in grayscale values between the antenna and the background image; uses the base station antenna pole as a reference point, and calculates the antenna downtilt angle based on a preset downtilt angle calculation formula; and determines whether the current base station downtilt angle needs to be adjusted based on the calculated antenna downtilt angle, the current base station antenna downtilt angle data collected by the tilt sensor, and the historical base station antenna downtilt angle data.

[0107] If the calculated antenna downtilt angle does not exceed the first preset range when compared with the current base station antenna downtilt angle data collected by the tilt sensor, the current base station antenna needs to be adjusted, and the electronic device remotely controls the base station antenna to adjust to the preset base station antenna downtilt angle according to the calculated antenna downtilt angle; if the calculated antenna downtilt angle does not exceed the second preset range when compared with the historical base station antenna downtilt angle data, the current base station antenna does not need to be adjusted, and the electronic device calibrates the tilt sensor according to the calculated antenna downtilt angle data.

[0108] A tilt sensor is used to monitor the mechanical downtilt angle of the base station antenna. When the downtilt angle is inaccurate, the downtilt angle of the base station antenna is adjusted in time to reduce the impact of inaccurate signal coverage caused by the inaccurate downtilt angle. The downtilt angle data of the base station antenna collected by the tilt sensor that exceeds the preset range is verified using drone image monitoring, thereby improving the accuracy of adjusting the downtilt angle of the base station antenna.
