Description

Technical Field

[0001] This invention relates to the field of communication base station technology, and more specifically to a device and method for adaptive optimization of the azimuth angle of communication base station antennas. Background Technology

[0002] Communication base stations are the core infrastructure of modern wireless communication networks. Their function is similar to an "aerial bridge," establishing a stable wireless connection between user mobile terminals (such as mobile phones and tablets) and the core network to transmit voice, data, and multimedia information. Physically, a base station typically consists of an antenna, a radio frequency (RF) unit, a baseband processing unit, and supporting power, transmission, and cooling systems. The antenna is responsible for receiving and transmitting radio waves, and its coverage area can be flexibly adjusted directionally or omnidirectionally according to environmental requirements. The RF unit is responsible for signal modulation, amplification, and transmission / reception. The baseband processing unit performs core processing tasks such as signal encoding / decoding and resource scheduling. Base stations are often deployed on towers, rooftops, or dedicated poles to obtain a wide line-of-sight transmission range and are interconnected with the core network via wired or microwave transmission links.

[0003] The elevation angle (also known as downtilt) of a communication base station antenna is a crucial and precise adjustment parameter in network optimization, directly and significantly impacting signal coverage quality, range, and interference levels. The elevation angle refers to the angle between the antenna's main beam (the direction of strongest signal energy) and the horizontal plane. When the elevation angle is 0 degrees, the antenna transmits horizontally, primarily used for extremely long-distance coverage. Typically, to effectively cover ground users, the antenna's elevation angle is set to a positive value, making the signal beam "look down" at the ground—this is downtilt. Its core function is to concentrate signal energy onto the target service area while reducing interference to distant co-frequency cells.

[0004] For example, patent application number 202410826337.1, entitled "AI Optimization Device for Adaptive Azimuth Angle of Communication Base Station Antenna," includes a support frame and a communication base station antenna. The communication base station antenna is connected to a direction adjustment component and an angle adjustment component. The direction adjustment component is used to adjust the left and right roll angles of the communication base station antenna in the horizontal direction, and the angle adjustment component is used to adjust the depression and elevation angles of the communication base station antenna. The direction adjustment component includes a direction adjustment motor and a first drive shaft. The first drive shaft is rotatably connected to the support frame, and the direction adjustment motor is bolted to the bottom of the support frame. The left and right roll angles and depression and elevation angles of the communication base station antenna are adjusted by the direction adjustment component and the angle adjustment component, respectively. The adjustment is convenient and has high stability. The device is compact and reasonable, easy to assemble, and can be regularly maintained by staff in the background.

[0005] However, after adjusting the azimuth angle of the communication base station antenna, this patent cannot guarantee that the communication base station antenna will remain stably at the current adjustment angle. When the communication base station antenna deviates by a certain angle, it cannot transmit the signal to the receiving ground with high strength and stability, which has certain defects.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

[0022] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0023] Example 1: like Figures 1 to 3 As shown, an embodiment of the present invention provides a communication base station antenna azimuth angle adaptive optimization device, including a movable mounting frame 1, a mounting plate 2, an angle adjustment component 3, and a rotation component 4.

[0024] Specifically, the movable mounting bracket 1 is installed on the communication base station tower. The movable mounting bracket 1 is used to movably install the communication base station antenna 5 and to connect the communication base station antenna 5 horizontally and vertically in the pitch direction.

[0025] The mounting plate 2 is installed at the output end of the movable mounting frame 1, and the mounting plate 2 is used to install the communication base station antenna 5.

[0026] The angle adjustment component 3 is connected to the mounting plate 2 via a transmission connection, and the angle adjustment component 3 is used to drive the mounting plate 2 to adjust the pitch angle.

[0027] The rotating component 4 is installed on the communication base station tower. The output end of the rotating component 4 is connected to the angle adjustment component. The rotating component 4 is used to drive the angle adjustment component and the mounting plate 2 to rotate in the horizontal direction.

[0028] In this embodiment, when the signal transmission angle between the signal receiving ground and the communication base station antenna 5 deviates, the rotating component 4 drives the angle adjustment component 3, the movable mounting bracket 1, and the mounting plate 2 to rotate horizontally. The communication base station antenna 5, located on the mounting plate 2, moves synchronously with the mounting plate 2. Simultaneously, the angle adjustment component 3 drives the mounting plate 2 and the communication base station antenna 5 to adjust their pitch angle. During this process, the movable mounting bracket 1 provides reliable support for the mounting plate 2 and the communication base station antenna 5, effectively ensuring that the communication base station antenna 5 remains stably at the current adjustment angle. This allows the communication base station antenna 5 to transmit high-intensity, stable communication signals to the terminal communication device, achieving a good communication environment between the communication base station antenna 5 and the terminal communication device.

[0029] Furthermore, two movable mounting frames 1 are symmetrically installed. Each movable mounting frame 1 includes a mounting sleeve 6, a rotating connector 7, and a telescopic connecting rod 8.

[0030] Specifically, the mounting sleeve 6 is rotatably mounted on the communication base station tower via the mounting bearing 9.

[0031] The rotating connector 7 is disposed on the outer side wall of the mounting sleeve 6, and the rotating connector 7 is used for rotating connection in the vertical direction.

[0032] The telescopic connecting rod 8 is connected at both ends to the rotating connecting piece 7 and the mounting plate 2, respectively.

[0033] In this embodiment, when the pitch angle of the mounting plate 2 and the communication base station antenna 5 needs to be adjusted, the angle adjustment component 3 drives the mounting plate 2 and the communication base station antenna 5 to rotate in the vertical direction. During this process, the telescopic connecting rod 8 swings around the rotating connecting piece 7, and at the same time, the telescopic connecting rod 8 achieves synchronous rotation with the mounting plate 2 through its own telescopic movement, so that the mounting plate 2 and the communication base station antenna 5 can be adjusted to a suitable pitch angle. The movable mounting bracket 1 can support and position the mounting plate 2 and the communication base station, effectively reducing the angular deviation of the mounting plate 2 and the communication base station antenna 5, thereby achieving stable adjustment of the pitch angle of the communication base station and ensuring a good communication environment between the communication base station antenna 5 and the terminal communication equipment.

[0034] In one specific embodiment, the mounting sleeve 6 includes a fixed sleeve 10 and a movable sleeve 11. Both the fixed sleeve 10 and the movable sleeve 11 have mounting cavities inside, and these mounting cavities match the mounting bearing 9. The fixed sleeve 10 and the movable sleeve 11 are both fitted onto the outside of the mounting bearing 9, and the fixed sleeve 10 and the movable sleeve 11 are detachably connected by bolts and nuts.

[0035] During the installation of mounting sleeve 6, the mounting bearing 9 is first fitted and installed onto the communication base station tower, preparing for the installation of mounting sleeve 6. Then, the fixed sleeve 10 and the movable sleeve 11 are fitted onto both ends of the mounting bearing 9 and joined together. Finally, bolts and nuts are used to tighten the fixed sleeve 10 and the movable sleeve 11, completing the installation of mounting sleeve 6. Mounting sleeve 6 can rotate around the communication base station tower, thereby allowing for horizontal adjustment of the rotation angle of mounting plate 2 and communication base station antenna 5.

[0036] It should be noted that the inner ring of the mounting bearing 9 can be a non-standard part, and the inner wall of the inner ring of the mounting bearing 9 can be set into a frustum shape. When the mounting bearing 9 is fitted onto the communication base station tower, the inner wall of the inner ring of the mounting bearing 9 can fit and contact the outer wall of the communication base station tower, thus achieving a reliable installation of the mounting bearing 9.

[0037] Furthermore, the rotating connector 7 includes a mounting base 12, a rotating shaft 13, and a connecting base 14.

[0038] Specifically, the mounting base 12 is installed on the outer wall of the mounting sleeve 6, and the mounting base 12 is provided with a rotation space.

[0039] The rotating shaft 13 is rotatably mounted on the inner wall of the rotating space.

[0040] The connecting seat 14 is fixedly installed on the rotating shaft 13, and the connecting seat 14 is in close contact with the inner wall of the rotating space.

[0041] In this embodiment, the rotating shaft 13 rotates in a vertical plane, and the connecting seat 14, which is fixedly connected to the rotating shaft 13, rotates synchronously with the rotating shaft 13. At this time, the rotating connecting parts 7 installed at both ends of the telescopic connecting rod 8 can realize the rotation of the telescopic connecting rod 8 in a vertical plane. When the upper telescopic connecting rod 8 retracts and the lower telescopic connecting rod 8 extends, the mounting plane of the mounting plate 2 rotates towards the sky. Conversely, when the upper telescopic connecting rod 8 extends and the lower telescopic connecting rod 8 retracts, the mounting plane of the mounting plate 2 rotates towards the ground. By combining these two methods, the elevation angle adjustment of the mounting plate 2 and the communication base station antenna 5 can be achieved.

[0042] The telescopic connecting rod 8 includes an outer sleeve 15 and an inner connecting rod 16. The outer sleeve 15 is fitted onto the outer wall of the inner connecting rod 16, and the outer sleeve 15 is in close and slidable contact with the inner connecting rod. The outer ends of the outer sleeve 15 and the inner connecting rod 16 are respectively threaded to two connecting seats 14. The telescopic connecting rod 8 achieves its telescopic function through the relative sliding between the outer sleeve 15 and the inner connecting rod 16, realizing dynamic adjustment of the elevation angle of the mounting plate 2 and the communication base station antenna 5.

[0043] Furthermore, the angle adjustment component includes a mounting bracket 17, an adjustment rack 18, a drive gear 19, and an adjustment motor 20.

[0044] Specifically, the mounting bracket 17 is fixedly mounted on the rotating assembly 4, and the mounting bracket 17 is provided with a positioning track 21 that matches the adjusting rack 18.

[0045] The adjusting rack 18 is fixedly installed on the back of the mounting plate 2, and the adjusting rack 18 is in close contact with the inner wall of the positioning track 21.

[0046] The drive gear 19 is rotatably mounted on the mounting bracket 17, and the drive gear 19 is meshed with the adjusting rack 18.

[0047] The regulating motor 20 is fixedly installed on the mounting bracket 17, and the output end of the regulating motor 20 is connected to the drive gear 19 for transmission.

[0048] In this embodiment, the adjusting rack 18 is configured in an arc shape, and both ends of the adjusting rack 18 are fixedly installed on the back of the mounting plate 2 by the mounting bracket. The mounting plate 2 rotates about the center of the adjusting rack 18 and adjusts the pitch angle.

[0049] When it is necessary to adjust the pitch angle of the mounting plate 2 and the communication base station antenna 5, the adjustment motor 20 is turned on, and the drive gear 19 rotates under the drive of the adjustment motor 20. In this case, the adjustment rack 18, which meshes with the drive gear 19, rotates, thereby driving the mounting plate 2 and the communication base station antenna 5 to rotate in the vertical direction, completing the pitch angle adjustment of the communication base station antenna 5. The direction of pitch angle adjustment of the mounting plate 2 and the communication base station antenna 5 is controlled by the rotation of the output shaft of the adjustment motor 20.

[0050] In one specific embodiment, the regulating motor 20 and the drive gear 19 are connected by a worm gear 22, which includes a transmission worm wheel and a drive worm. The transmission worm wheel is fixedly mounted on the mounting shaft of the drive gear 19. The drive worm is rotatably mounted on the mounting bracket 17 and is meshed with the transmission worm wheel. The input end of the drive worm is connected to the regulating motor 20.

[0051] The adjusting motor 20 and the drive gear 19 are connected by a worm gear 22. The self-locking action of the worm gear 22 ensures that the mounting plate 2 and the communication base station antenna 5 remain stably in their current positions, effectively preventing positional shifts and guaranteeing a good communication environment between the communication base station antenna 5 and the terminal communication equipment. Specifically, the self-locking of the worm gear 22 occurs when the adjusting motor 20 is not activated; the self-locking action between the drive worm and the transmission worm gear prevents the transmission worm gear from rotating, thus ensuring that the mounting plate 2 and the communication base station antenna 5 do not experience angular shifts.

[0052] It should be noted that the regulating motor 20 is a servo motor. A servo motor is an engine that controls the operation of mechanical components in a servo system; it is a type of auxiliary motor with indirect speed change. Servo motors can control speed with very high positional accuracy, converting voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it is used as an actuator and has characteristics such as a small electromechanical time constant and high linearity. It can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. The regulating motor 20, being a servo motor, can precisely control the rotation angle of the drive gear 19, and thus precisely control the pitch angle of the mounting plate 2 and the communication base station antenna 5.

[0053] Furthermore, the rotating assembly 4 includes a hub motor 23 and a transmission connecting ring 24.

[0054] Specifically, the hub motor 23 is fixedly installed on the tower of the communication base station, and the hub motor 23 is used to output rotational power.

[0055] The transmission connecting ring 24 is fixedly installed at the output end of the hub motor 23, and the transmission connecting ring 24 is fixedly connected to the mounting bracket 17.

[0056] In this embodiment, when it is necessary to adjust the horizontal rotation angle of the communication base station antenna 5, the hub motor 23 is turned on, and the hub motor 23 drives the transmission connecting ring 24 to rotate, thereby realizing the adjustment of the horizontal rotation angle of the communication base station antenna 5.

[0057] Example 2: like Figure 4 As shown, the present invention also discloses a communication base station that employs the antenna azimuth adaptive optimization device described in Embodiment 1. The communication base station includes a tower, on which the antenna azimuth adaptive optimization device is mounted.

[0058] Specifically, multiple angle adjustment components, movable mounting brackets, and mounting plates are installed in a circular array on a single rotating component. The communication base station antennas located on the mounting plates are distributed in a circular array, enabling the transmission and reception of communication signals around the tower. Furthermore, to cover a larger area, the communication base station antennas can be distributed in multiple layers along the vertical direction of the tower.

[0059] Example 3: like Figure 5 As shown, this invention discloses an adaptive optimization method for the azimuth angle of a communication base station antenna, comprising the following steps: S100, Gain Acquisition: Using the communication base station as the center, the signal gain is acquired around the communication base station and a signal gain map is generated.

[0060] In this embodiment, after the communication base station is installed, on-site technicians can use a spectrum analyzer or signal source and power meter to measure the signal gain and generate a signal gain map based on the location of the on-site technicians.

[0061] S200, Manual Adjustment: Based on the signal gain map and the spatial distribution of terminal communication equipment, the signal gain is set on the signal gain map.

[0062] In this embodiment, on-site technicians can set the signal gain based on the spatial distribution of current users. For example, if area A has a large population, the signal gain for that area can be set to high gain. Conversely, if the population is small, the signal gain for that area can be set to low gain. This setting ensures stable signal communication within the coverage area at the current stage.

[0063] S300, Data Transmission: The signal gain map, after the signal gain setting is completed, is transmitted to the communication base station. The communication base station analyzes the signal gain map and adjusts the azimuth angle of the communication base station antenna.

[0064] S400, Dynamic Feedback: When the terminal communication device is communicating, it transmits the signal gain data to the communication base station, and the communication base station dynamically adjusts the azimuth angle of the communication base station antenna according to the signal gain.

[0065] In this embodiment, due to changes in user spatial location distribution and population migration data, the communication base station can periodically collect signal gain data of the communication terminal equipment and adaptively adjust the azimuth angle of the communication base station antenna to meet the signal stability requirements of the terminal communication equipment.

[0066] Compared with the prior art, the present invention has at least the following beneficial effects: This invention adjusts the horizontal rotation angle and pitch angle of the communication base station through a rotation component and an angle adjustment component, enabling the communication base station to generate the maximum signal transmission strength to the signal receiving ground. This effectively ensures that the signal receiving ground can achieve high-strength and stable signal transmission and communication with the communication base station antenna, and guarantees a good communication environment between the communication base station antenna and the terminal communication equipment. It features a simple structure and convenient operation.

[0067] Furthermore, the present invention can scan the communication distribution points in the communication area and obtain communication point information, and can automatically complete the position matching between the communication base station antenna and the signal receiving point, thereby completing the adjustment of the horizontal rotation angle and pitch angle of the communication base station antenna, ensuring that the signal receiving point has a good communication environment and effectively guaranteeing the stability of communication. The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
