[0063] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0064] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0065] like Figure 1 As shown, Figure 1 This is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiments of this application.

[0066] The terminal in this application embodiment can be a PC, or a smartphone, tablet computer, e-book reader, MP3 (Moving Picture Experts Group Audio Layer III) player, MP4 (Moving Picture Experts Group Audio Layer IV) player, portable computer, or other portable terminal devices with display functions.

[0069] Those skilled in the art will understand that Figure 1 The terminal structure shown does not constitute a limitation on the terminal and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0072] Reference Figure 2 This application provides an antenna management and control method applied to a user service analysis module. The antenna management and control method includes:

[0073] Step S100: Obtain user MDT data for the target area;

[0074] Step S200: Based on the user MDT data and the preset scanning range, the target area is scanned to obtain the target orientation angle and the target downtilt angle;

[0075] In step S300, the antenna azimuth angle and the target downtilt angle are sent to the parameter management module, so that the parameter management module can generate adjustment instructions based on the existing network antenna parameters and output the adjustment instructions to the antenna adjustment subsystem, so that the antenna adjustment system can adjust the antenna azimuth angle and downtilt angle according to the adjustment instructions to complete the antenna adjustment optimization.

[0076] The specific steps are as follows:

[0077] Step S100: Obtain user MDT data for the target area;

[0078] In this embodiment, it should be noted that the antenna management and control method can be applied to the user service analysis module, which belongs to the antenna management and control system, and the antenna management and control system belongs to the antenna management and control equipment.

[0079] In this embodiment, a specific application scenario may be:

[0080] Due to frequent base station network access and rapid changes in the regional environment, frequent optimization and adjustment of antenna azimuth and downtilt angles are necessary. However, because the range of base station installations varies depending on office and residential areas, there is a significant tidal effect within the range, resulting in uneven utilization of communication base stations. The traditional method of manually judging and adjusting antenna azimuth and downtilt angles by network optimization personnel lacks accuracy and timeliness, leading to a certain degree of lag in network optimization services.

[0081] In this application, the antenna management and control system includes a user service analysis module. This module performs sector and radial scans of the target area. Based on the user MDT data of the target area and the scan range, it determines the patterns and trends of user distribution and activity, and uses this as a basis to determine the target coverage area. It then obtains the target azimuth angle and target downtilt angle of the antenna, i.e., the optimal solution for the antenna's radio frequency attitude. This changes the manual judgment method for network adjustment, obtaining accurate antenna adjustment parameters. The antenna azimuth angle and the target downtilt angle are sent to the parameter management module, which generates adjustment instructions based on the existing network antenna parameters and outputs these instructions to the antenna adjustment subsystem. The antenna adjustment subsystem then adjusts the antenna azimuth angle and downtilt angle according to the adjustment instructions to complete the antenna adjustment optimization. Thus, by combining the user service analysis module, the parameter management module, and the antenna adjustment system, a complete network optimization system is formed, which can automatically and quickly complete the adjustment of the antenna configuration.

[0082] That is, in this application, the inaccuracy and untimely adjustment of the antenna due to manual judgment and adjustment of the antenna azimuth and downtilt angle are avoided.

[0083] In this embodiment, the area where the antenna needs to be adjusted is determined. This area can be an office area or a residential area, and is not limited in this embodiment.

[0084] The system reads in user MDT (Minimization of Drive-tests) data from the target area and analyzes the distribution and activity patterns and trends of users within that area to determine the optimal radio frequency (RF) orientation of the antenna. It's important to note that users can be 4G users. As long as users within the target area have their GPS (Global Positioning System) enabled and support MDT functionality, the terminal can acquire user latitude and longitude information, network signal strength information, and other MDT data. The terminal can then automatically report this MDT data, including user location information, to the base station or the operator's network management backend, allowing the user service analysis module to access the user MDT data.

[0085] The target area refers to the area that the antenna's network signal needs to cover. This area includes residential areas, office areas, etc. The area's operating parameters are obtained, and the horizontal scanning range, i.e., the target area, is determined by using the area's operating parameters and the antenna's current network mechanical orientation angle.

[0086] As an example, if the antenna rotates too much, the network signal wave may exceed the area to be radiated, affecting other areas. Therefore, conventional antenna devices have a maximum coverage area, i.e., the target area. For example, if the maximum antenna rotation angle is 120 degrees, the target area is determined to be Azimuth ± 60° based on the existing network's mechanical heading angle Azimuth.

[0087] In this embodiment, to avoid significant tidal effects within the target area, user MDT data for the target area is acquired at regular time intervals. This allows for timely adjustment of the antenna's radio frequency attitude, i.e., the target azimuth angle and target downtilt angle, based on real-time user MDT data from the target area. Therefore, user MDT data for users in the target area is acquired according to preset time and frequency, where the preset time and frequency are set based on server characteristics or application provider settings.

[0088] Step S200: Scan the target area based on the user MDT data and the preset scanning range to obtain the target orientation angle and the target downtilt angle;

[0089] In this embodiment, based on the base station location of the antenna, a single scan range is set. The target area is scanned according to the scan range. During the scan, user MDT data within each scan range is recorded to obtain the number of users within that scan range. By comparing the number of users within each scan range, the scan range with the largest number of users is determined. The current antenna network signal beam should mainly cover the area corresponding to this scan range. At this time, the antenna's RF attitude is optimal. The azimuth angle and downtilt angle of the antenna when it is in this optimal RF attitude are obtained, thereby obtaining the target azimuth angle and target downtilt angle.

[0090] It is understandable that the target orientation angle and target downtilt angle obtained from the analysis of the current user MDT data in the target area are the optimal radio frequency attitude of the antenna. Adjusting the antenna according to the parameters of this optimal radio frequency attitude can maximize the utilization rate of the wireless communication base station by users in the target area.

[0091] The scanning process includes sector scanning and radial scanning. Sector scanning involves scanning multiple times within a target area, using the antenna base station as the scanning reference point, within a defined sector scanning range and step size, to determine the antenna adjustment azimuth angle. Radial scanning, based on the determined antenna azimuth angle, adjusts the antenna's downtilt angle. Specifically, it involves scanning the area corresponding to the antenna azimuth angle determined by sector scanning within a defined step size from the antenna base station to the maximum radius of the target area, thereby determining the antenna adjustment downtilt angle and obtaining the final main radiation area after antenna adjustment, where the network signal is optimal.

[0092] The specific steps for determining the target orientation angle during the process of scanning the target area based on the user MDT data and the preset scanning range to obtain the target orientation angle and the target downtilt angle are as follows:

[0093] Step S210: Perform a fan-shaped scan of the target area based on a preset scanning range, and determine the initial coverage area with the largest user proportion and the target direction angle corresponding to the initial coverage area based on the user MDT data.

[0094] In this embodiment, the preset scanning range refers to the range of a single scan that determines the antenna's radio frequency or radiation area. This scanning range is set by the administrator and is usually determined based on the antenna's operating parameters. Therefore, before performing a sector scan on the target area, the scanning range is determined to ensure that the range size of each scan is consistent, facilitating the comparison of the number of users within different directional angle scanning ranges and determining the antenna directional angle.

[0095] Specifically, the steps for determining the scanning range are as follows:

[0096] Step A1: Obtain the antenna parameters of the target area, including antenna mounting height and antenna transmission angle;

[0097] Step A2: Calculate the scanning radius of the scanning range based on the antenna mounting height;

[0098] Step A3: The scanning range is formed based on the scanning radius and the antenna emission angle.

[0099] In this embodiment, antenna parameters of the target area are obtained, such as the location of the antenna base station, antenna mounting height, and antenna transmission angle. The antenna mounting height is the installation height of the antenna. This data can be obtained by calculating the height of the building where the antenna is installed and the length or height of the antenna (the height of the building plus the distance from the support frame to the midpoint of the antenna). Alternatively, it can be obtained from the operator, where antenna parameters are collected or stored.

[0100] The maximum radial distance of the scan, i.e., the scan radius R, is determined based on the antenna mounting height. The calculation formula is as follows:

[0101]

[0102] Where H is the antenna mounting height, and C° is an empirical value of the antenna downtilt angle obtained from historical data testing. Since the greater the antenna downtilt, the larger the antenna coverage area, in order to avoid affecting the coverage status of other areas, C is usually set to 3° according to the antenna operating parameters. At this time, 3° is the coverage boundary of the scanning process. Substituting 3° into the above formula (1), we get

[0103]

[0104] The purpose of determining the antenna's RF attitude is to determine the optimal antenna coverage area and improve antenna utilization by adjusting the antenna's RF attitude based on real-time changes in the number of users in the target area. Therefore, during the scanning process, the shape of the scanning range is a sector formed by the antenna base station's location as the base point, the scanning radius R, and the antenna's emission angle. The antenna emission angle refers to the antenna's radiation angle; the antenna signal is valid within the radiation angle, while the signal weakens or disappears beyond the radiation angle. The antenna emission angle is usually obtained from the antenna's operating parameters. For example, if the antenna emission angle is 65°, the scanning range is a sector formed by the antenna base station as the base point, with an angle of 65 degrees and a radius of R.

[0105] A sector scan is performed within the target area to determine the antenna azimuth angle.

[0106] As an example, see reference Figure 3 A fan-shaped scan is performed within the target area of ​​the existing network's mechanical orientation angle Azimuth ± 60° in a 65-degree sector pattern to determine the orientation angle corresponding to the scan range with the largest number of users, thus obtaining the target orientation angle Azimuth. new The scanning direction can be clockwise, and the center bisector of the 65-degree sector is the target azimuth of the antenna. That is, the center bisector and the starting line of the target area scanning form the antenna azimuth angle.

[0107] In this embodiment, the step of performing a fan-shaped scan of the target area based on a preset scanning range, and determining the initial coverage area with the largest user proportion and the target orientation angle corresponding to the initial coverage area based on the user MDT data, includes:

[0108] Step B1: Based on a preset scanning range and a preset scanning step size, perform a fan-shaped scan on the target area to obtain at least one fan-shaped scanning range;

[0109] Step B2: Determine the initial coverage area based on the user MDT data and the at least one sector scan range;

[0110] Step B3: Record the orientation of the initial coverage area to obtain the target orientation angle.

[0111] In this embodiment, a fan-shaped scan is performed on the target area based on the scan range obtained above. During the scan, the target area is scanned multiple times step by step using a preset scan step size to obtain at least one fan-shaped scan range. It can be understood that if the fan-shaped scan is performed clockwise from the left edge of the target area, the scan range is a 65-degree fan, the target area is Azimuth±60°, and the scan step size is 10 degrees, then the left edge of the 65-degree fan coincides with the left edge of Azimuth±60°, and the antenna azimuth angle is 32.5°, which is taken as the first fan-shaped scan range. When scanning again with a preset scan step size of 10 degrees, the 65-degree fan rotates 10 degrees clockwise, and the antenna azimuth angle is 42.5 degrees. The scan range under this angle state is taken as the second fan-shaped scan range. Thus, based on the preset scan step size, a fan-shaped scan is performed on the target area to obtain multiple fan-shaped scan ranges.

[0112] The preset scanning step size is determined by relevant management personnel based on the accuracy of the scanning data. The smaller the scanning step size, the more precise the scanning process. For example, a sector scan with a scanning step size of 5 degrees is more precise than a sector scan with a scanning step size of 10 degrees, resulting in a higher target orientation angle (Azimuth) for the antenna. new The more accurate.

[0113] It should be noted that when performing multiple sector scans with a preset scan step size, there is a maximum limit to the number of sector scans due to the boundary of the target area. In other words, there is a maximum limit to the antenna azimuth angle. It can be understood that within the target area of ​​Azimuth±60°, when a 65-degree sector is scanned with a scan step size of 10 degrees, the maximum antenna azimuth angle is 82.5 degrees.

[0114] In this embodiment, during the fan-shaped scanning of the target area, based on the user MDT data of the target area, the proportion of the number of users within each fan-shaped scanning range to the total number of users in the target area is recorded, and the corresponding antenna azimuth angle is output. Finally, the value with the largest proportion of users among all the output antenna azimuth angles is selected as the target azimuth angle. The fan-shaped scanning range corresponding to the target azimuth angle is then the initial coverage range. This achieves the determination of the optimal target azimuth angle (Azimuth) based on real-time user changes within the target area and the existing network azimuth angle of the antennas. new This is to determine the maximum horizontal utilization rate of wireless communication base stations.

[0115] The step of determining the initial coverage area based on the user MDT data and the at least one sector scan range includes:

[0116] Step B21: Based on the user MDT data, calculate the ratio of the number of users within the at least one sector scan range to the number of users in the target area, and obtain at least one user ratio value.

[0117] Step B22: Take the user percentage value with the largest value among the at least one user percentage values ​​to obtain the target percentage value;

[0118] Step B23: Obtain the sector scanning range corresponding to the target user percentage value to obtain the initial coverage range.

[0119] In this embodiment, based on user MDT data, the number of users within each sector scan range is recorded, and the ratio of this number to the number of users in the target area is calculated to obtain a user percentage value. Thus, multiple sector scans based on the scan step size will yield multiple user percentage values. The user percentage value with the largest value among these multiple values ​​is taken as the target percentage value. It can be understood that the sector scan range corresponding to the target percentage value has the largest number of users compared to other sector scan ranges; therefore, the sector scan range corresponding to the target percentage value is the main coverage area of ​​the antenna communication network information, i.e., the initial coverage area.

[0120] The specific steps for determining the target downslope angle are as follows:

[0121] Step S220: Perform a radial scan on the initial coverage area, and obtain the target coverage area where the user proportion value meets the preset conditions and the target downtilt angle corresponding to the target coverage area based on the user MDT data.

[0122] In this embodiment, the initial coverage area is radially scanned to determine the target coverage area that meets the preset conditions within the initial coverage area. This target area is the main radiation area of ​​the antenna base station when it is working. That is, the number of users in the target coverage area is the largest, the utilization rate of the antenna communication base station is the largest, and the antenna signal is optimal. The antenna downtilt angle under this radio frequency attitude is the target downtilt angle.

[0123] Specifically, the step of performing a radial scan of the initial coverage area and obtaining the target coverage area where the user percentage value meets a preset condition and the target downtilt angle corresponding to the target coverage area based on the user MDT data includes:

[0124] Step C1: Perform a radial scan on the initial coverage area based on a preset initial radius and scanning stride to obtain the radial scan range;

[0125] Step C2: When the radial scanning range meets the preset conditions, stop scanning to obtain the target coverage area;

[0126] Step C3: Record the downtilt angle of the antenna corresponding to the target coverage area to obtain the target downtilt angle.

[0127] In this embodiment, refer to Figure 4The preset initial radius refers to the starting radius of the radial scan. This initial radius can be determined based on the antenna's operating parameters and adjustment / optimization requirements. The scan step size refers to the increment of the radius during the radial scan. Based on the initial radius, the antenna base station location, and the scan range, a sector-shaped scan range is determined. After a single scan, the scan radius is expanded by the increment corresponding to the scan step size to achieve radial scanning and obtain multiple radial scan ranges. It can be understood that if the initial radius is Range... ori =100 meters(Range ori <R, where R is the scanning radius), and the scanning step is Step = 10 meters, then at the determined target orientation angle Azimuth new Starting from a location 100 meters away from the antenna base station, a radial scan is performed within the range of [100, R]. When the initial radius is 100 meters, a radial scan is performed on the initial coverage area to obtain a radial scan range. With an increment of 10 meters, when the initial radius is 110 meters, a radial scan is performed on the initial coverage area to obtain a new radial scan range.

[0128] During radial scanning, scanning stops when the radial scanning range meets preset conditions, obtaining the target coverage area. The antenna downtilt angle at the target coverage state is recorded; this angle is the target downtilt angle. The preset conditions can be a preset ratio of the number of users within the current radial scanning range to the number of users within the target area. The number of users within the scanning range is obtained from user MDT data. When the preset ratio is 70%, the preset condition is that the number of users in the current scanned small sector is 70% of the total sector user data, at which point scanning stops, and the current radial scanning range becomes the target coverage area.

[0129] It should be noted that, in one example, a radial scan is performed on the initial coverage area based on a preset initial radius and scan stride. The radial scan range and the number of users within each scan range are recorded, and the ratio of users in the radial scan range to the number of users in the target area is calculated. After the radial scan is completed, the radial scan range that meets preset conditions is selected to obtain the target coverage area. It can be understood that if multiple radial scan ranges meet the preset conditions after the scan is completed, the target coverage area is determined according to the preset selection requirements.

[0130] The step of recording the downtilt angle of the antenna corresponding to the target coverage area to obtain the target downtilt angle includes:

[0131] Step C31: Obtain the radial coverage radius corresponding to the target coverage area, wherein the radial coverage radius is obtained from the initial radius and the scanning stride;

[0132] Step C32: Calculate the target downtilt angle based on the radial coverage radius.

[0133] In this embodiment, after determining the target coverage area, the radial coverage radius (Range) of the target coverage area is obtained. new The radial coverage radius is determined by the initial radius and the scanning step size. It can be understood that multiple radial scans expand the scanning radius incrementally with the scanning step size, based on the initial radius. If the second radial scan determines the target coverage area, then the radial coverage radius (Range) is... new The data is obtained by adding the scanning step size to the initial radius.

[0134] Based on the radial coverage radius, the antenna beam downtilt angle is calculated as follows:

[0135]

[0136] Among them, Tilt new Anvha is the target downtilt angle, and Anvha is the antenna's vertical half-power angle, which is obtained from the antenna's operating parameters.

[0137] In step S300, the antenna azimuth angle and the target downtilt angle are sent to the parameter management module, so that the parameter management module can generate adjustment instructions based on the existing network antenna parameters and output the adjustment instructions to the antenna adjustment subsystem, so that the antenna adjustment system can adjust the antenna azimuth angle and downtilt angle according to the adjustment instructions to complete the antenna adjustment optimization.

[0138] It should be noted that the antenna management and control system includes a user service analysis module, a parameter management module, and an antenna adjustment subsystem. The parameter management module manages the parameters of the base station's antenna system and adjusts and optimizes the target azimuth and target downtilt angle data output by the user service analysis module. This data is then sent to the antenna adjustment subsystem in the target area for execution. The antenna adjustment subsystem controls the antenna's azimuth and downtilt angle according to the adjustment and optimization instructions to complete the adjustment and optimization.

[0139] The antenna subsystem includes a remote azimuth adjustment module, a remote downtilt adjustment module, and a remote information acquisition module. The remote azimuth adjustment module controls the antenna's azimuth adjustment by comparing the current azimuth information acquired by the remote information acquisition module with the antenna's current azimuth information to provide power for azimuth adjustment. The remote downtilt adjustment module controls the antenna's downtilt adjustment by comparing the current downtilt information acquired by the remote information acquisition module with the antenna's current downtilt information to provide downtilt power. The remote information acquisition module collects and monitors the antenna's operating status, providing a basis for managing and adjusting antenna parameters.

[0140] This application provides an antenna management and control method, system, device, and storage medium. Compared with existing technologies where antenna RF attitude adjustment accuracy is low and network optimization services suffer from a certain degree of lag, this application obtains user MDT data of the target area; scans the target area based on the user MDT data and a preset scanning range to obtain the target azimuth angle and target downtilt angle; sends the antenna azimuth angle and target downtilt angle to a parameter management module, which then generates adjustment instructions based on existing network antenna parameters and outputs these instructions to an antenna adjustment subsystem. The antenna adjustment subsystem then adjusts the antenna azimuth angle and downtilt angle according to the adjustment instructions to complete antenna adjustment optimization. In other words, this application performs sector and radial scans of the target area, determines the patterns and trends of user distribution and activity based on the user MDT data of the target area and scanning range, and uses this as a basis to determine the target coverage area of ​​the target area, obtaining the target azimuth angle and target downtilt angle of the antenna, i.e., the optimal solution for the antenna's RF attitude. This changes the manual judgment method for network adjustment and obtains accurate antenna adjustment parameters. The antenna azimuth and target downtilt angle are sent to the parameter management module, which generates adjustment instructions based on the existing network antenna parameters and outputs these instructions to the antenna adjustment subsystem. The antenna adjustment subsystem then adjusts the antenna azimuth and downtilt angle according to the instructions to complete the antenna adjustment optimization. Thus, by combining the user service analysis module, parameter management module, and antenna adjustment system, a complete network optimization system is formed, which can automatically and quickly complete the adjustment of antenna configuration.

[0141] Based on the above-mentioned antenna management and control method, this application also provides an antenna management and control system, which includes a user service analysis module, a parameter management / adjustment module, and an antenna adjustment subsystem.

[0142] The user business analysis module is used to acquire user MDT data of the target area, and scan the target area based on the user MDT data and the preset scanning range to obtain the target orientation angle and the target downtilt angle.

[0143] The parameter management module is used to receive the target azimuth angle and the target downtilt angle, collect the existing network antenna parameters of the target area, match the existing network antenna parameters with the target azimuth angle and the target downtilt angle, generate an adjustment command, and send the adjustment command to the antenna adjustment subsystem;

[0144] The antenna adjustment subsystem is used to receive the adjustment command and adjust the antenna's azimuth and downtilt angle to complete the antenna adjustment optimization. The antenna adjustment subsystem includes a remote information acquisition module, a remote downtilt angle adjustment module, and a remote azimuth angle adjustment module.

[0145] Optionally, user MDT data of the target area is acquired, and the target area is scanned based on the user MDT data and a preset scanning range to obtain the target azimuth angle and the target downtilt angle. The antenna azimuth angle and the target downtilt angle are sent to the parameter management module, so that the parameter management module can generate adjustment instructions based on the existing network antenna parameters and output the adjustment instructions to the antenna adjustment subsystem, so that the antenna adjustment subsystem can adjust the antenna azimuth angle and downtilt angle according to the adjustment instructions to complete the antenna adjustment optimization.

[0146] Optionally, refer to Figure 5 The parameter management / adjustment module includes a parameter management center, a parameter center, an instruction orchestration center, an instruction issuance center, and a user management center.

[0147] Among them, reference Figure 6 The parameter management center and parameter verification center are responsible for verifying, collecting, and managing various engineering parameters of the new antenna adjustment system, and storing them in detail for use as a basis for user analysis platforms.

[0148] Command orchestration center: Matches various adjustment data output from the user business analysis center with the live network data from the parameter management center, and finally generates adjustment commands to output to the command issuance center.

[0149] Command Issuance Center: Issues commands generated by the orchestration center and verification center. It also includes OMC (Operation and Maintenance Center) queuing management function for adjusting and collecting commands for new antenna adjustment systems. This allows it to manage multiple antenna base stations, serve base stations across the entire network, achieve multi-cell collaborative scheduling, and eliminate service absorption in special scenarios.

[0150] User Management Center: Responsible for user authentication, verification, role assignment, etc., and is the parameter management hub.

[0151] Optionally, refer to Figure 7 The antenna adjustment subsystem is divided into three parts: remote azimuth adjustment module 100, remote downtilt adjustment module 200, and remote information acquisition module 300. All three parts have AISG (antenna interface standards group) control lines 400.

[0152] The main components and operating principle of the antenna remote azimuth adjustment module (ARAA) are as follows:

[0153] The antenna remote azimuth adjustment module consists of a remote steering control unit (RSCU), a remote steering power unit (RSPU), and a remote steering follow-up unit (RSSU). The function and operating principle of this device are as follows:

[0154] refer to Figure 8 The steering control unit (RSCU) is the core of the antenna control system. The steering control unit includes an aviation plug 101, a Hall sensor 102, a geared motor 103, a housing 104, a main control board 105, and a hexagonal output connector 106.

[0155] This unit is controlled by an ARM chip. According to the instructions from the AIMS (Autonomous Internet Management System), it sends start or stop commands to the remote steering and remote tilt via the AISG control line. It compares the running signals returned by these two units with the signals detected by the attitude sensing chip to determine whether the AIMS command was executed successfully. It can also perform signal verification and self-correct attitude. A protection device is set up to promptly cut off the power to protect the system in case of abnormal operation. The steering control unit is equipped with a complete lightning protection structure. The steering control unit is directly connected to the network communication device (NCD) in the base station equipment room and can accept a wide voltage input of 12V-60V. The steering control unit is the power provider and controller of the remote steering device.

[0156] refer to Figure 9 The power steering unit (RSPU) is the executor of power. The power steering unit includes a reducer 201, a backplate 202, a drive shaft 203, an output flange 204, a clamp 205, a spherical bearing 206, an RTD connector 207, an RSCU interface 208, and a rain cover 209.

[0157] This unit outputs power to the output shaft through a reducer, generating an output torque of not less than 30 N.M. It is connected to the remote tilting device (RTD) through the output shaft and spherical bearings, and then connected to the antenna through the remote tilting mechanism (RTD), enabling the antenna to rotate around the mast. The maximum rotation angle is ±60°. It can withstand a torque of more than 150 N.M in a static state and has a wind resistance level exceeding level 12.

[0158] refer to Figure 10 The steering follower unit (RSSU) is a passively rotating mechanism that is a freely rotating unit connecting the antenna to the mast. The steering follower unit includes a clamp 301, an output flange 302, a shaft 303, an antenna connector 304, a pressure bearing 305, a feed line fixing bracket 306, and a bearing body 307.

[0159] The antenna rotates freely in a circular motion using a transmission shaft and a planar bearing, while an antenna feeder mounting bracket is installed to prevent the feeder head from becoming loose when the antenna rotates.

[0160] The main components and operating principle of the Remote Antenna Downtilt Adjustment (ARTA) module are as follows:

[0161] The remote tilt device consists of a remote tilt control unit (RTCU) and a remote tilt support unit (RTBU). The function and operating principle of this device are as follows:

[0162] refer to Figure 11 The tilt control unit (RTCU) is the power provider and controller for tilting. The tilt control unit has a similar structure to the RSCU, and the attitude sensing chip is 401.

[0163] This unit receives commands from the remote steering control unit (RSCU) to start or stop the motor and reports the number of motor operating pulses, which can facilitate recording the motor's operating status. At the same time, this unit is equipped with an attitude chip to monitor the antenna attitude. The attitude monitoring chip is mainly composed of an MPU6050 nine-axis attitude sensor, which can detect the angle and angular velocity of the antenna in the X, Y, and Z axes and report the information to the remote steering control unit (RSCU), where the main control unit collects and judges the antenna attitude.

[0164] refer to Figure 12 The tilting support unit (RTBU) is the actuator of the tilting mechanism. The tilting support unit includes a combined bearing 501, a needle roller pressure bearing 502, an RTCU interface 503, a support frame 504, a combined bearing 505, and a lead screw drive device 506.

[0165] This unit uses a stable double-triangle structure and a T-shaped screw drive to pull the rhombus mechanism, causing the rhombus mechanism to stretch or contract diagonally to generate thrust or pull force, which has the effect of pushing the antenna down.

[0166] After the RTCU is installed on the RTBU, it operates as the antenna tilts down. Antenna tilt reference. Figure 13 and Figure 14 .

[0167] Because the four supports of the RTBU structure are of the same length, the lead screw is always vertical and equally divides the rhomboid mechanism. The downward tilt angle of the lead screw is always half of the downward tilt angle of the antenna. This method can be used to reconstruct the antenna downward tilt angle. The relationship between the antenna and the lead screw angle is as follows: Figure 15 As shown. The antenna tilts down from AO to CO. Since the lead screw BD is always perpendicular to and bisects AC equally, and AO equals CO, BO is the height of the isosceles triangle. Therefore, the tilt angle of the lead screw is always half the tilt angle of the antenna.

[0168] Both RSCU and RTCU, as important control components of the system, have unique codes for easy system identification. The RTBU consists of a support plate, a lead screw drive, signal and power-off switches, combined bearings, needle roller pressure bearings, etc., and its structure is as follows:

[0169] like Figure 15 As shown, the RTBU consists of a rhomboid structure composed of four support plates. A lead screw drive is placed at points A and C of the rhomboid structure. Rotation of the lead screw changes the distance between points A and C, thereby changing the distance between points B and D. Needle roller bearings are installed at the joints of the support plates to reduce friction. A combined bearing is added at the joint between points A and C to prevent gaps, ensuring a robust, durable, and smooth-running structure. This structure can support a weight of over 1,000 kg, far exceeding the weight of the antenna. The lead screw drive is made of 304 stainless steel, and the threads use wide-spaced T-shaped threads to prevent rust or malfunctions caused by falling foreign objects. The RTBU design fully considers various outdoor usage scenarios, and the structure can operate for extended periods within a temperature range of -40℃ to 80℃.

[0170] The main components and operating principle of the Antenna Remote Acquisition and Adjustment Module (ARGI) are as follows:

[0171] The antenna remote acquisition and adjustment module is a highly integrated GPS L1 & BeiDou B1I dual-frequency communication base station antenna attitude monitoring device. (Refer to...) Figure 16 This module includes an MCU processing unit, a GPS / BD dual-mode receiver, a gyroscope, etc. It can measure azimuth, downtilt, and roll angles, and provide information such as latitude, longitude, and elevation. It can monitor the attitude and position of objects such as antennas in real time. It only needs to be set up on an antenna that can receive positioning signals to complete the measurement of the attitude and position of the communication base station antenna.

[0172] The features of the antenna remote information acquisition module are as follows:

[0173] Automation: Automatic collection of operating parameters of all types of base station antennas across the entire network, 24 / 7, at all times.

[0174] Real-time performance: One-time installation enables real-time detection and collection of engineering parameter data, providing more accurate and timely feedback on basic network information.

[0175] High efficiency: Dynamic analysis of real-time data and models enables timely detection of abnormal changes in antenna operation and provides early warnings. Timely maintenance is also ensured, with a reverse monitoring mechanism.

[0176] Accuracy: Resistant to multipath effects, high precision. Azimuth accuracy ±2 degrees; mechanical tilt accuracy ±1 degree; latitude / longitude / altitude accuracy 10 meters;

[0177] Low cost: It uses ordinary GPS navigation chips, and the receiver, antenna and algorithm are all designed and developed in-house.

[0178] In this embodiment, the user service analysis module calculates the coverage area of ​​the target area based on the user MDT data of the target area and outputs the target azimuth and target downtilt angles that the antenna needs to cover. The user service analysis module inputs the output target azimuth and target downtilt angle information of the antenna in the target area to the parameter management / adjustment module. The parameter management / adjustment module sends a collection command to the target area through the platform to collect the current azimuth and downtilt angles of the antenna in the target area. The parameter management / adjustment module matches the current antenna azimuth and downtilt angles fed back with the target azimuth and target downtilt angles of the target area, and after passing through the command orchestration center, finally generates an adjustment command. The antenna adjustment subsystem adjusts the azimuth and downtilt angles through the AISG control line according to the finally generated command to complete the adjustment and optimization. The parameter management / adjustment module collects the latest antenna operating parameters and completes the database update.

[0179] In this embodiment, based on user MDT data of the target area, the distribution range and activity patterns of users are determined. Accurate target azimuth and downtilt angles are obtained through sector scanning and radial scanning. Adjustment commands are automatically generated by the parameter adjustment platform and sent to the antenna adjustment subsystem, thereby remotely adjusting the azimuth and downtilt angles of the antennas in the target area, achieving rapid network optimization. Thus, by combining the user service analysis module, parameter management / adjustment module, and antenna adjustment subsystem, a complete network optimization system is formed. This system can accurately and effectively adjust network structure and coverage quality. Compared to traditional methods of manual judgment plus electrically adjusted antennas or traditional tower-mounted adjustments, it improves network optimization quality, significantly enhances user experience, and saves labor costs for network optimization by automatically and quickly adjusting antenna configurations.
