Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and particularly to an electronically controlled antenna adjustment system. Background Art

[0002] In the engineering design of mobile communication networks, base station antennas should be reasonably selected according to actual situations such as network coverage requirements, traffic distribution, anti-interference requirements, and network service quality. When setting up base station antennas, parameters such as the downtilt angle, azimuth angle, antenna hanging height, antenna diversity distance, and isolation distance need to be considered.

[0003] It is a conventional optimization method for communication base station antennas to achieve the network coverage effect by adjusting the pitch angle and horizontal angle. Traditional antennas clamp the pole through a spiral fastening structure, and by adjusting the tightness with the pole, the antenna can rotate around the pole to adjust the horizontal angle. The pitch angle can be adjusted through the pitch angle adjustment structure above. However, during the adjustment, it is necessary for workers to climb to a high altitude for manual operation, and the adjustment efficiency is very low. Moreover, it is very difficult to adjust the horizontal angle with this structure, and it is difficult for a single person to complete. With the construction of 5G communication base stations, 5G antennas are different from traditional antennas. Usually, they weigh 50KG, which is 3 - 5 times that of traditional antennas. One person cannot complete the adjustment independently, and manual operation is difficult. In addition, due to the high requirement for angle accuracy and large adjustment frequency of 5G antennas, manual operation cannot effectively meet the requirements.

[0004] Currently, most of the automatic adjustment methods integrate an electronic adjustment module inside the antenna, enabling the antenna to perform pitch angle adjustment of 0 - 12°, but do not have the function of horizontal angle adjustment. Electric adjustment and remote adjustment solutions do not meet the usage conditions due to various problems. Chinese patent document CN206059663U discloses an antenna angle adjustment device, which includes an azimuth angle adjustment device and a downtilt angle adjustment device. Two clamping components, upper and lower, are fixedly installed on the pole. The downtilt angle adjustment device includes a first fixed seat, a first mounting seat, and a second mounting seat. The first fixed seat and the second mounting seat are respectively hinged to the upper and lower clamping components to achieve rotation in the vertical direction. One end of the first mounting seat is hinged to the other end of the first fixed seat. The azimuth angle adjustment device includes an upper rotating mounting plate and a lower rotating mounting plate. The upper rotating mounting plate is hinged to the first mounting seat, and the lower rotating mounting plate is hinged to the second mounting seat, thereby achieving rotation in the horizontal direction. When adjusting the antenna, the horizontal angle of the antenna is adjusted through the azimuth angle adjustment device, and the pitch angle is adjusted through the downtilt angle adjustment device. However, it has serious defects: in this solution, when the downtilt angle adjustment device extends, the rotation axis of the azimuth angle adjustment device also forms an angle with the ground. When the azimuth angle adjustment device controls the antenna to rotate, it does not move in the horizontal plane, resulting in the azimuth angle adjustment device losing the purpose of adjusting the azimuth.

[0020] The technical solution of the present invention has the following advantages:

[0021] 1. An electronically controlled antenna adjustment system provided by the present invention includes: a first connection structure, which includes a first fixing member and a telescopic arm. The first fixing member is detachably connected to a pole. One end of the telescopic arm is hinged to the first fixing member at a first hinge axis, the first hinge axis is perpendicular to the ground, and the other end of the telescopic arm is hinged to an antenna at a second hinge axis, the second hinge axis is parallel to the ground; a second connection structure, which includes a second fixing member and a connecting arm. The second fixing member is located below the first fixing member and is detachably connected to the pole. One end of the connecting arm is hinged to the second fixing member at a third hinge axis, the third hinge axis is perpendicular to the ground, and the other end of the connecting arm is hinged to the antenna at a fourth hinge axis, the fourth hinge axis is parallel to the ground; an electronic control system, which is respectively connected to the first connection structure and the second connection structure, and is used to control the telescopic arm and / or the connecting arm to swing in the horizontal direction, and control the telescopic arm to drive the upper part of the antenna to approach or move away from the pole. The telescopic arm and the connecting arm can swing left and right in the horizontal direction to achieve azimuth angle adjustment; the telescopic arm can make the upper part of the antenna approach or move away from the pole, and the connecting arm keeps the distance between the lower part of the antenna and the pole unchanged to achieve pitch angle adjustment. Since the first hinge axis and the third hinge axis are fixedly arranged in this solution and are always perpendicular to the ground, the adjustment range of the azimuth angle will not change with the change of the pitch angle, and the problem that the azimuth angle adjustment function loses its original purpose caused thereby is also overcome.

[0022] 2. In the electronically controlled antenna adjustment system provided by the present invention, the telescopic arm includes a first arm and a second arm hinged at a fifth hinge axis. The first arm is hinged to the first fixing member, and the second arm is hinged to the antenna. It also includes a first push rod connected to the electronic control system. The push rod is respectively connected to the first arm and the second arm. When the push rod is in a contracted state, the telescopic arm is retracted, and when the push rod is extended, the telescopic arm is deployed. The volume and weight of the antenna will also increase with the improvement of requirements. The weight of existing antennas can reach dozens of kilograms, and at the same time, the windward area is large and the wind pressure is high. If a gear transmission or other methods are used, when the telescopic arm extends, the bending moment is large, and stress concentration occurs at the fifth hinge axis. This solution uses a push rod to drive the telescopic arm to move, thereby forming a triangular structure and eliminating the problem of stress concentration at the fifth hinge axis, making the structure stable while keeping the length of the telescopic arm adjustable.

[0023] 3. An electronically controlled antenna adjustment system provided by the present invention, wherein the first arm includes a straight arm member and a horizontal rotating member. The horizontal rotating member is hinged to the first fixing member at the first hinge axis, the straight arm member is hinged to the horizontal rotating member at the seventh hinge axis, the seventh hinge axis is parallel to the ground, and the straight arm member is hinged to the fifth hinge axis. The contact surface between the horizontal rotating member and the first fixing member is a plane. When the telescopic arm rotates around the axis, the horizontal rotating member makes the rotation stable and also provides space for installing the first push rod.

[0024] 4. An electronically controlled antenna adjustment system provided by the present invention, wherein a relief groove is provided on the first arm or the second arm for making way for the first push rod to avoid interference between the telescopic arm and the first push rod when the telescopic arm is retracted. Due to the limitation of the minimum volume of the push rod, in order to prevent the telescopic arm from being interfered by the push rod when it is retracted, a relief groove is opened at the corresponding position for the telescopic arm to pass through.

[0025] 5. An electronically controlled antenna adjustment system provided by the present invention, wherein a push rod support structure is provided on the first arm or the second arm provided with the relief groove. The push rod support structure is arranged on one side close to the fifth hinge axis and extends in the direction away from the second arm or the first arm not provided with the relief groove. This push rod support structure is used to provide a connection fulcrum for the push rod passing through the relief groove.

[0026] 6. An electronically controlled antenna adjustment system provided by the present invention further includes a second push rod connected to the electronic control system. The two ends of the second push rod are respectively connected to the first fixing member and the telescopic arm, or respectively connected to the second fixing member and the connecting arm, and are used to drive the telescopic arm or the connecting arm to rotate around the axis. The second push rod, the second fixing member, and the connecting arm form a triangle in structure. Compared with using other transmission methods, using a push rod to control the rotation of the connecting arm makes the structure more stable, thus meeting the requirements of large-weight antennas such as 5G requirements.

[0027] 7. An electronically controlled antenna adjustment system provided by the present invention may be such that one end of the second push rod is rotatably connected to the first fixing member or the second fixing member, and the other end is hinged to the corresponding telescopic arm or the connecting arm at the sixth hinge axis. This solution ensures that the second push rod, the second fixing member, and the connecting arm form a triangle in structure, and two of the three vertices are fixed, so the structure is stable.

[0028] 8. Another possible configuration of the electric control antenna adjustment system provided by the present invention is that the second push rod and the connecting arm or the telescopic arm form a crank and connecting rod structure. One end of the second push rod is slidably and rotatably connected to the first fixing member or the second fixing member, and the other end is hinged to the corresponding telescopic arm or the connecting arm at the sixth hinge axis. Compared with the previous solution, this solution can achieve a larger azimuth angle adjustment. However, due to the freedom of the sliding direction between the second push rod and the second fixing member, it is less stable than the previous solution.

[0029] 9. The electric control system of the electric control antenna adjustment system provided by the present invention includes an angle feedback mechanism. The angle feedback mechanism includes a gyroscope provided on the antenna for obtaining the pitch angle of the antenna. The angle also includes an azimuth sensor provided on the third hinge axis. The azimuth sensor measures the change in the relative position between the connecting arm and the third hinge axis. The electric control system includes a wireless control module for returning the data obtained by the angle feedback mechanism to the console and receiving the control instructions of the console to operate the movement of the antenna. The gyroscope transmits data in real time, and the refresh frequency is not less than 50Hz. This solution has a reset mode and a calibration mode. Combining the bracket structure size, the basic adjustment of the angles in two dimensions is achieved by calibrating the internal function of the bracket angle and the telescopic distance of the stepping motor push rod. To further reduce the angle deviation, the gyroscope is used to continuously monitor the real-time angle state of the bracket, feedback the data to the console, and judge and analyze the current angle. The motor action is controlled by the feedback measurement method of continuous approximation to reach the real angle set by the console, and the real azimuth angle and pitch angle are reflected on the upper computer interface. The angle information is transmitted in real time to reduce errors.

[0030] 10. The electric control antenna adjustment system provided by the present invention further includes a self-locking device for locking the relative positions of all components after the angle is determined, keeping the adjusted angle unchanged, and not being affected by factors such as the environment and its own weight. It can also solve the problem of insufficient structural stability when using the crank and connecting rod solution.

[0031] 11. The electric control system of the electric control antenna adjustment system provided by the present invention is encapsulated in a semi-closed metal box with a notch. The side of the metal box with the notch is used to place the exposed hardware interfaces. The side with the hardware notch is recessed, and the notch is downward during installation. It can play a role in preventing rain and snow and shielding electromagnetic interference. For the interference sources and easily interfered components in the circuit, anti-interference design is adopted in the circuit board design. Comprehensive means such as space isolation, electrical isolation, noise suppression circuit, filter circuit, watchdog circuit, multi-layer circuit board, and shielding cover are used to improve the anti-interference ability of the system. The metal shielding package can be used in the field environment, is waterproof and resistant to high-frequency electromagnetic radiation, and can protect its data to be stable and reliable.

[0041] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] Figure 1 and Figure 2An electronically controlled antenna adjustment system provided by the present invention is shown, including: a first connection structure, including a first fixing member 1 and a telescopic arm. The first fixing member 1 is detachably connected to a pole 4. One end of the telescopic arm is hinged to the first fixing member 1 at a first hinge shaft 5 perpendicular to the ground, and the other end of the telescopic arm is hinged to the antenna at a second hinge shaft 6 parallel to the ground; the telescopic arm includes a first arm 2 and a second arm 3 hinged at a fifth hinge shaft 12. The first arm 2 is hinged to the first fixing member 1. The first arm 2 includes a straight arm member and a horizontal rotating member. The horizontal rotating member is hinged to the first fixing member at the first hinge shaft. The straight arm member is hinged to the horizontal rotating member at a seventh hinge shaft 18 parallel to the ground. The straight arm member is hinged to the fifth hinge shaft 12. The second arm 3 is hinged to the antenna. It further includes a first push rod 13 connected to the electronic control system. The push rod is respectively connected to the first arm 2 and the second arm 3. When the push rod is in a contracted state, the telescopic arm is retracted. When the push rod is extended, the telescopic arm is deployed. The volume and weight of the antenna will also increase with the improvement of requirements. The volume of the existing antenna can reach dozens of kilograms. If a gear drive or other methods are used, when the telescopic arm extends, the bending moment is relatively large, and stress concentration occurs at the fifth hinge shaft 12. In this solution, a push rod is used to drive the telescopic arm to move, thereby forming a triangular structure and eliminating the problem of stress concentration at the fifth hinge shaft 12, making the structure stable while keeping the length of the telescopic arm adjustable. A relief groove 14 is provided on the first arm 2 for making way for the first push rod 13 to avoid interference between the telescopic arm and the first push rod 13 when the telescopic arm is retracted. Due to the limitation of the minimum volume of the push rod, in order to prevent the telescopic arm from being interfered by the push rod when the telescopic arm is retracted, a relief groove 14 is opened at the corresponding position for the telescopic arm to pass through. A push rod support structure 15 is provided on the first arm 2 provided with the relief groove 14. The push rod support structure 15 is arranged on the side close to the fifth hinge shaft 12 and extends in the direction away from the second arm 3 without the relief groove 14. The push rod support structure 15 is used to provide a connection fulcrum for the push rod passing through the relief groove 14. Of course, the relief groove 14 and the push rod support structure 15 can also be provided on the second arm 3, and then the connection direction of the first push rod 13 can be adjusted adaptively.

[0043] It also has a second connection structure, including a second fixing member 7 and a connecting arm 8. The second fixing member 7 is located below the first fixing member 1 and is detachably connected to the pole 4. One end of the connecting arm 8 is hinged to the second fixing member 7 at a third hinge shaft 9, and the third hinge shaft 9 is perpendicular to the ground. The other end of the connecting arm 8 is hinged to the antenna at a fourth hinge shaft 10, and the fourth hinge shaft 10 is parallel to the ground; an electric control system, which is respectively connected to the first connection structure and the second connection structure, is used to control the connecting arm 8 to swing in the horizontal direction, and to control the telescopic arm to drive the upper part of the antenna to approach or move away from the pole 4. The telescopic arm and the connecting arm 8 can swing left and right in the horizontal direction to achieve azimuth adjustment; the telescopic arm can make the upper part of the antenna approach or move away from the pole 4, and the connecting arm 8 keeps the distance between the lower part of the antenna and the pole 4 unchanged to achieve pitch angle adjustment. It also includes a second push rod 16 connected to the electric control system, which is respectively connected to the second fixing member 7 and the connecting arm 8 and is used to drive the connecting arm 8 to rotate around the axis. Of course, the two ends of the second push rod 16 can also be respectively connected to the first fixing member 1 and the telescopic arm, and it can also play the role of adjusting the azimuth angle. The second push rod 16, the second fixing member 7, and the connecting arm 8 form a triangle in structure. Compared with using other transmission methods, using a push rod to control the rotation of the connecting arm 8 makes the structure more stable, so as to meet the requirements of large-weight antennas such as 5G requirements. One end of the second push rod 16 is rotatably connected to the second fixing member 7, and the other end is hinged to the corresponding connecting arm 8 at a sixth hinge shaft 17. This solution ensures that the second push rod 16, the second fixing member 7, and the connecting arm 8 form a triangle in structure, and 2 of the 3 vertices are fixed, so the structure is stable. As another implementation manner, it can also be that the second push rod 16 and the connecting arm 8 or the telescopic arm form a crank and connecting rod structure. One end of the second push rod 16 is slidably and rotatably connected to the first fixing member 1 or the second fixing member 7, and the other end is hinged to the corresponding telescopic arm or connecting arm 8 at a sixth hinge shaft 17. Compared with the previous solution, this solution can achieve a larger azimuth angle adjustment, but due to the freedom of the sliding direction between the second push rod 16 and the second fixing member 7, it is less stable than the previous solution. Since the first hinge shaft 5 and the third hinge shaft 9 are fixedly arranged in this solution and are always perpendicular to the ground, the adjustment range of the azimuth angle will not change with the change of the pitch angle, and the problem that the azimuth angle adjustment function loses its original purpose caused by this is also overcome.

[0044] The electric control system includes an angle feedback mechanism, including a gyroscope provided on the antenna for obtaining the pitch angle of the antenna, and also includes an azimuth sensor provided on the third hinge shaft 9, such as Figure 3As shown, the azimuth sensor measures the change in the relative position between the connecting arm and the third hinge axis 9. The electronic control system includes a wireless control module, which is used to return the data obtained by the gyroscope to the console and receive the control instructions from the console to operate the antenna movement. The gyroscope transmits data in real time, and the refresh frequency is not less than 50Hz. This solution has a reset mode and a calibration mode. Combining with the bracket structure size, the basic adjustment of the angle in two dimensions is realized by calibrating the internal function of the bracket angle and the telescopic distance of the stepping motor push rod. To further reduce the angle deviation, cooperate with the gyroscope to always master the real-time angle state of the bracket, feedback the data to the console and judge and analyze the current angle, and use the feedback measurement to continuously approach the way to control the motor action, so as to reach the real angle set by the console, and reflect the real azimuth angle and pitch angle at this time on the upper computer interface. The angle information is transmitted in real time to reduce errors. It also includes a self-locking device, which is used to lock the relative positions of all components after the angle is determined, keep the adjusted angle unchanged, and is not affected by factors such as the environment and its own weight. It can also solve the problem of insufficient structural stability when using the crank-link mechanism. The electronic control system is encapsulated in a semi-closed metal box 11 with a notch. The side of the metal box 11 with the notch is used to place the exposed hardware interface. The side with the hardware notch is recessed, and the notch is downward during installation. It can play the role of preventing rain and snow and shielding electromagnetic interference. For the interference sources and easily interfered components in the circuit, anti-interference design is adopted in the circuit board design. Comprehensive means such as space isolation, electrical isolation, noise suppression circuit, filter circuit, watchdog circuit, multi-layer circuit board, and shielding cover are used to improve the anti-interference ability of the system. The metal shielding package can be used in the field environment, is waterproof and resistant to high-frequency electromagnetic radiation, and can protect its data to be stable and reliable. There is also a scale marked around the third hinge axis 9 on the second connecting piece, as an alternative, which is convenient for manual angle adjustment.

[0045] This device has the characteristics of high load-bearing, stably loads 70KG, and at the same time has good wind resistance. When hanging on the windward side of the antenna with a length of 0.5m 2 , it can resist a 16-level wind with a wind pressure of 2.0KN / m 2 .

[0046] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
