Description

Technical Field

[0001] This application relates to the technical field of antenna adjustment devices, and particularly to antenna adjustment devices and antennas. Background Art

[0002] With the acceleration of the 5G construction process, indoor is the main application scenario of 5G. In the 4G era, 70% of applications occurred indoors, and this data will increase to 85% in the 5G era. At the same time, 5G indoor applications put forward higher requirements for in-depth coverage. In particular, indoor multi-partition scenarios such as residential communities have always been the key points and difficulties of 4 / 5 network coverage of indoor distribution systems.

[0003] Currently, the conventional coverage method for the window-facing and outdoor areas of residential communities is to install antennas on metal masts on the roof and cover the opposite buildings. This brings a problem that when the antenna is directly installed using a U-shaped hoop and the receiving angle of the antenna needs to be adjusted, the U-shaped hoop and the antenna need to be disassembled and assembled for adjustment to achieve the adjustment of the antenna angle, and the adjustment difficulty is relatively high. Summary of the Invention

[0051] Figure 1It is a circuit schematic diagram of the antenna adjustment device shown in the embodiments of the present application.

[0052] See Figures 1-5 , the first aspect of the present application provides an antenna adjustment device, including:

[0053] The mounting component 200 is used for mounting the antenna body 100, and the antenna body 100 is located on the side of the mounting component 200;

[0054] The rotation positioning component 300, the mounting component 200 is mounted on the rotation positioning component 300, and the rotation positioning component 300 can drive the mounting component 200 to rotate to adjust the angle of the antenna body 100; and

[0055] The lifting component 400, the rotation positioning component 300 is arranged at one end of the lifting component 400, the other end of the lifting component 400 is used for connecting with the floor surface, and the lifting component 400 is used for driving the rotation positioning component 300 to rise or fall relative to the floor surface.

[0056] The antenna adjustment device and antenna of the present application, the antenna adjustment device includes a mounting component 200, a rotation positioning component 300 and a lifting component 400, the antenna body 100 is mounted on the side of the mounting component 200, the mounting component 200 is mounted on the rotation orientation component, when the rotation positioning component 300 rotates, it drives the mounting component 200 to rotate, so that the antenna body 100 rotates with the mounting component 200 to achieve the effect of adjusting the angle of the antenna body 100, the rotation positioning component 300 is arranged on the lifting component 400, and the lifting component 400 is used to drive the rotation positioning component 300 and the mounting component 200 to rise or fall relative to the floor surface to adjust the rise and fall of the antenna body 100. Effectively solve the technical problem that when the antenna is directly installed by a U-shaped clamp and the receiving angle of the antenna needs to be adjusted, it is necessary to disassemble and assemble the U-shaped clamp and the antenna for adjustment to achieve the adjustment of the antenna angle, and the adjustment difficulty is relatively high. It is convenient to adjust the angle and lift of the antenna, so that the antenna can better adjust the receiving signal according to different requirements in terms of angle and height.

[0057] In the embodiments of the present application, the mounting component 200 includes:

[0058] The support column is mounted on the rotation positioning component 300, and the rotation positioning component 300 can drive the mounting component 200 to rotate;

[0059] The antenna arm is mounted on the side of the support column and is used for mounting the antenna body 100 thereon.

[0060] The antenna boom can be integrated with the support column or fastened to the side of the support column with screws. The antenna body 100 can be installed on the antenna boom by bolts, screws or snap connection, so that when the support column rotates, it drives the antenna boom and the antenna thereon to rotate, thereby adjusting the receiving angle of the antenna body 100.

[0061] In this embodiment, the rotation positioning component 300 can include a motor and a transmission device. The transmission device can be a gear. For example, the output gear is installed on the motor, and the input gear is installed on the mounting component 200. The output gear and the input gear mesh with each other. The output gear is driven by the motor to drive the input gear to rotate, thereby driving the mounting component 200 to rotate (H azimuth).

[0062] The lifting device can include a hydraulic cylinder or an electric cylinder, etc. The rotation positioning component 300 is installed on the telescopic rod of the hydraulic cylinder or the electric cylinder. The hydraulic cylinder and the electric cylinder are installed on the floor surface. The output of the electric cylinder and the hydraulic cylinder is used to drive the rotation positioning component 300, the mounting component 200 and the antenna to move up and down, thereby realizing the movement of the antenna in the up and down directions (V azimuth).

[0063] In this embodiment, it can also include:

[0064] A controller, electrically connected to the rotation positioning component 300 and the lifting component 400.

[0065] The controller can be an STM32 single-chip microcomputer, which is connected to the RRU in the wireless network subsystem through the AISG interface module, and finally accesses the base station network management system through the base station transmission network. The base station network management system issues control instructions for adjusting the H (horizontal) azimuth of the rotation positioning component 300 and the V (vertical) azimuth of the lifting component 400 of the antenna adjustment device.

[0066] In some embodiments, according to the requirements of mobile network optimization, the base station network management system issues adjustment instructions for the antenna adjustment device in the H (horizontal) azimuth of the rotation positioning component 300 and / or the V (vertical) azimuth of the lifting component 400. The instructions are sent through the base station transmission network to the RNC of the wireless network subsystem (RNS) to the BBU and then to the RRU. The STM32 single-chip microcomputer is connected to the RRU through the AISG communication protocol, and the instructions are finally sent to the STM32 single-chip microcomputer. The STM32 single-chip microcomputer drives the corresponding rotation positioning component 300 and lifting component 400 to complete the instructions according to the adjustment instructions for the H (horizontal) azimuth of the rotation positioning component 300 and / or the V (vertical) azimuth of the lifting component 400. Thus, the azimuth adjustment of the antenna adjustment device and the remote collaborative management of the base station network management system are realized.

[0067] In some embodiments of the present application, the rotation positioning component 300 includes:

[0068] The first driver 310 is connected to the mounting member 200 and is configured to drive the mounting member 200 to rotate.

[0069] The horizontal turntable 320 is disposed on the lifting member 400, and the mounting member 200 is rotatable relative to the horizontal turntable 320.

[0070] The locking member is connected to the horizontal turntable 320 and the mounting member 200, and has a locked state and a released state. When the locking member is in the locked state, the mounting member 200 is locked with the horizontal turntable 320. When the locking member is in the released state, the mounting member 200 is rotatable relative to the horizontal turntable 320.

[0071] In this embodiment, the first driver 310 drives the mounting member 200 to rotate, so that the antenna on the mounting member 200 rotates with the mounting member 200 to achieve the angle adjustment of the mounting member 200.

[0072] The first driver 310 may be a motor and a driving gear. An internal gear or an external gear is provided on the mounting member 200. The driving gear is disposed on the output shaft of the motor, and the driving gear meshes with the internal gear or the external gear. The motor drives the driving gear to drive the internal gear or the external gear to drive the mounting member 200 to rotate.

[0073] In the related art, the antennas are all disposed on the floor surface and are easily blown by strong winds, resulting in the deviation of the antenna coverage direction, thereby affecting the signal acquisition of the antenna.

[0074] In this embodiment, the horizontal turntable 320 is mounted on the horizontal turntable 320 by welding or bolt connection. The horizontal turntable 320 may include mounting holes. The mounting member 200 passes through the mounting holes and has a clearance fit with the mounting holes, so that the mounting member 200 can rotate relative to the horizontal turntable 320. Alternatively, bearings may be provided on the mounting holes. The mounting member 200 is connected to the inner ring of the bearing, and the mounting holes are connected to the outer ring of the bearing, so that the mounting member 200 can rotate relative to the horizontal turntable 320.

[0075] One end of the locking member is mounted on the mounting member 200 and can rotate with the mounting member 200. The other end can be engaged with the horizontal turntable 320 to form the locked state of the locking member, so that the mounting member 200 is locked because the locking member is engaged with the horizontal turntable 320, that is, the mounting member 200 cannot rotate relative to the horizontal turntable 320. When the other end of the locking member is not in contact with the horizontal turntable 320, the released state of the locking member structure is formed. At this time, the first driver 310 can be used to control the mounting member 200 to rotate relative to the horizontal turntable 320.

[0076] With the locking component and the horizontal turntable 320 of this embodiment, the antenna can not only rotate but also be locked on the horizontal turntable 320 when the appropriate angle is found. In this way, the antenna is locked, and even when blown by the wind, the antenna will not shift. Thus, the problem that the antenna is easily affected by strong winds, resulting in a deviation in the antenna coverage direction and affecting the signal acquisition of the antenna, is avoided.

[0077] In some embodiments of the present application, the horizontal turntable 320 has a plurality of angular slots 321. The vertical projections of the respective angular slots 321 are arranged in an arc with the vertical projection of the axis of the mounting component 200 as the center. The locked state of the locking component is that at least a part of the locking component is inserted into the angular slot 321.

[0078] In this embodiment, the angular slot 321 can be a through slot. A part of the locking component is inserted into any one of the angular slots 321, so that while the locking component is restricted, the rotation of the mounting component 200 is also restricted. Thus, the antenna can be locked, and the problem that the antenna shifts under the blowing of strong winds is avoided.

[0079] In some embodiments of the present application, the locking component includes:

[0080] A positioning rod 331, rotatably connected to the mounting component 200 and capable of rotating with the mounting component 200;

[0081] A buckle 332, arranged on the positioning rod 331, and at least a part of the buckle 332 extends a joint portion relative to the lower surface of the positioning rod 331;

[0082] An elastic member 333, one end connected to the mounting component 200, the other end connected to the positioning rod 331, and capable of rotating with the mounting component 200. The elastic member 333 is used to provide an upward acting force for the positioning rod 331;

[0083] A relay 334, connected to the mounting component 200 and capable of rotating with the mounting component 200. The relay 334 is located below any one of the angular slots 321. When the relay 334 is powered on, it generates magnetism to adsorb the buckle 332 located above it, so that at least a part of the locking component is inserted into the angular slot 321 to form the locked state of the locking component. When the relay 334 is powered off, under the action of the elastic member 333, the positioning rod 331 drives the buckle 332 to pop out of the angular slot 321 to form the released state of the locking component.

[0084] In this embodiment, the positioning rod 331 and the buckle 332 can be integrally formed, or can be arranged together by means such as welding, bolt connection or snap connection. The buckle 332 extends and protrudes from below the positioning rod 331 so as to be inserted into the angle slot 321. The buckle 332 can be made of metal or magnet. One end of the positioning rod 331 is hinged to the mounting member 200.

[0085] In this embodiment, the elastic member 333 can be a spring or an elastic rubber band, etc. The mounting member 200 horizontally extends a part of the first boss. One end of the elastic member 333 is connected to the first boss, and the other end of the elastic member 333 is connected to the positioning rod 331. The elastic member 333 is located below the positioning rod 331, and the elastic member 333 can rotate with the mounting member 200. When the positioning rod 331 moves downward and the buckle 332 is inserted into the angle slot 321, the elastic member 333 is compressed and has an upward acting force. In the case where the buckle 332 is released from the angle slot 321, the elastic member 333 can drive the buckle 332 to separate outward through the upward acting force after compression.

[0086] In this embodiment, for the convenience of control, the locking member further includes a relay 334. The mounting member 200 horizontally extends a part of the second boss. The relay 334 is arranged on the second boss. The relay 334 rotates synchronously with the mounting member 200. The relay 334 is located below the angle slot 321. When the relay 334 is powered on, the buckle 332 is adsorbed by the relay 334, so that the buckle 332 drives the positioning rod 331 to move downward. At this time, the elastic member 333 is compressed, and the buckle 332 is inserted into the angle slot 321, so that the locking member is in a locked state, and the mounting member 200 and the horizontal turntable 320 are locked. When the relay 334 is powered off, the relay 334 loses the acting force for adsorbing the buckle 332. The upward elastic force generated by the elastic member 333 after compression at this time pops the buckle 332 outward, driving the buckle 332 to drive the positioning rod 331 to move upward, and the buckle 332 disengages from the angle slot 321, so that the locking member is in a released state, the mounting member 200 and the horizontal turntable 320 are released, and the mounting member 200 can rotate relative to the horizontal turntable 320.

[0087] In this embodiment, by introducing the relay 334, the locking state and the released state of the locking member can be automatically switched, without the need for an operator to operate manually, which is convenient and fast.

[0088] In some embodiments, a power supply and a switch can also be configured. The power supply is electrically connected to the relay 334, and the switch is connected in series between the power supply and the relay 334 to control the relay 334 to be powered on or off.

[0089] In some embodiments of the present application, the horizontal turntable 320 has an avoidance groove 322, the avoidance groove 322 has the same radian as the angle slot 321 but different radii, and the elastic member 333 passes through the avoidance groove 322.

[0090] In this embodiment, in order to save space conveniently, the first boss is located below the horizontal turntable 320, and the avoidance groove 322 is provided on the horizontal turntable 320, so that when the elastic member 333 rotates with the installation component 200, it will not conflict with the horizontal turntable 320.

[0091] In some embodiments of the present application, it further includes:

[0092] A first position sensor 335, arranged on the positioning rod 331;

[0093] A plurality of second position sensors 336, each of the second position sensors 336 is located on one side of the corresponding angle slot 321, and a position signal is generated when the first position sensor 335 contacts any one of the second position sensors 336;

[0094] A controller, electrically connected to the first driver 310, the first position sensor 335 and the corresponding second position sensor 336, and is used to determine the current angular position of the installation component 200 when receiving the position signal, and control the first driver 310 to drive the installation component 200 to rotate.

[0095] In this embodiment, the plurality of second position sensors 336 are respectively arranged on the horizontal turntable 320 and on one side near each angle slot 321, so that when the positioning rod 331 moves down and the buckle 332 is inserted into one of the angle slots 321, the first position sensor 335 contacts the corresponding second position sensor 336, generates an electrical signal and sends it to the controller. At this time, the controller can clearly know the current angular position of the installation component 200 rotating in this direction, and can drive the installation component 200 to rotate in the forward or reverse direction by controlling the first driver 310 to adjust the angle of the antenna.

[0096] In this embodiment, the controller is an STM32 single-chip microcomputer.

[0097] After receiving the H (horizontal) azimuth adjustment degree instruction, the STM32 single-chip microcomputer controls the H (horizontal) azimuth adjustment process as follows:

[0098] STEP1: The system operator issues an H (horizontal) azimuth adjustment degree and direction instruction according to the H (horizontal) azimuth adjustment degree requirement and the historical position information of the contact return first position sensor 335 and the corresponding second position sensor 336 on the horizontal turntable 320;

[0099] STEP2: After the H (horizontal) azimuth adjustment degrees and direction are sent to the STM32 single-chip microcomputer, the STM32 single-chip microcomputer controls the disconnection of the input power supply of the relay 334. The magnetism of the relay 334 disappears, and the elastic member 333 pulls the buckle 332 on the positioning rod 331 to separate from the relay 334 to achieve unlocking;

[0100] STEP3: According to the horizontal rotation angle requirement, the STM32 single-chip microcomputer controls the first driving member to drive the mounting member 200 to rotate. The step size of each rotation is 15 degrees. If it is necessary to rotate 45 degrees, the motor needs to rotate 3 times;

[0101] STEP4: After the horizontal angle of the antenna is adjusted in place, the STM32 single-chip microcomputer controls the relay 334 to be powered on to generate magnetism, adsorb and pull the buckle 332 on the positioning rod 331 to connect with the relay 334 to achieve locking;

[0102] STEP5: The first position sensor 335 and the corresponding second position sensor 336 are at the position where the horizontal turntable 320 is located to record position information for the next horizontal adjustment.

[0103] Operation mode of the motor rotation control component of the first driver 310

[0104] In some embodiments, the motor of the first driver 310 uses a two-phase stepper motor (basic step angle is 1.8 degrees) to control the rotation of the antenna.

[0105] 1) Rotation accuracy and number of pulses. Since the rotation angle each time is 15 degrees, in order to improve the accuracy, through a microstepping driver, the rotation angle of the stepper motor under the action of each pulse can be further subdivided by 20. The rotation angle of the stepper motor under the action of each pulse is 0.09 degrees, so the number of pulses required for one rotation is 15 / 0.09 ≈ 167. At the same time, since the STM32 single-chip microcomputer can provide DC 3.3V and 5V voltages, and the input voltage of this stepper motor is DC 12V, the antenna adjustment device in this embodiment is also equipped with a DC 5V to DC 12V boost conversion module to supply power to the stepper motor.

[0106] 2) Motor torque calculation. The weight that the stepper motor needs to drive in rotation is 35 kg, including 15 kg for the antenna and 20 kg for the antenna adjustment device. The stepper motor is connected to the antenna adjustment device and the antenna through transmission mechanisms such as gears and chains. According to the stepper motor torque calculation formula: T = (M * g) / (2 * π * n * η), where M is the mass of the object (unit: kg), g is the acceleration due to gravity (unit: N / kg), n is the rotational speed of the stepper motor (unit: revolutions per minute), and η is the efficiency of the transmission mechanism. The rotational speed of this stepper motor is 100 revolutions per minute, the efficiency of the transmission mechanism is 0.8, and the acceleration due to gravity is 9.81 m / s2 , by calculating, the torque that the stepper motor needs to provide is approximately: T = (35 * 9.81) / (2 * π * 100 * 0.8) = 0.976 N·m.

[0107] 3) Rotation control mode, such as Figure 5 As shown, when the stepper motor needs to rotate in the positive half-axis direction, the STM32 single-chip microcomputer issues an instruction. The stepper motor control module inputs the voltage of the stepper motor with terminal a as the positive pole and terminal b as the negative pole, and the stepper motor rotates 15 degrees each time. When the positioning rod 331 rotates to 60 degrees on the positive half-axis, the position sensor at the +60 degree position on the positive half-axis controls and returns the warning position information to the STM32 single-chip microcomputer through the first position sensor 335 and the corresponding second position sensor 336 of the contact sensor module. The STM32 single-chip microcomputer controls the stepper motor control module to disconnect the voltage input to the stepper motor, and the stepper motor stops rotating, playing a role of idle rotation protection. When the stepper motor needs to rotate in the negative half-axis direction, the STM32 single-chip microcomputer controls the stepper motor control module to input the voltage of the stepper motor with terminal a as the negative pole and terminal b as the positive pole. The positive and negative poles of the stepper motor voltage change, and the rotation direction of the stepper motor changes immediately, and the positioning rod 331 rotates in the opposite direction.

[0108] In some embodiments, the horizontal turntable 320 is a flange plate, and the holes on the flange plate are angular slots 321. The holes on the flange plate correspond to adjustable degrees and are all circular holes. State 1: When it is necessary to adjust the azimuth of the antenna H (horizontal), the STM32 single-chip microcomputer controls the relay 334 control module to input a voltage of 0V to the relay 334 at the bottom of the flange plate. After the relay 334 loses magnetism, the positioning rod 331 is pulled by the elastic member 333 to disengage from the hole on the flange plate, and the antenna is in a state where the H (horizontal) azimuth can be adjusted. State 2: After the horizontal angle of the antenna is adjusted, the STM32 single-chip microcomputer controls the relay 334 control module to energize the relay 334 at the bottom of the flange plate. After the relay 334 generates positive and negative magnetic poles due to electromagnetic induction, it automatically attracts the buckle 332 on the positioning rod 331. The buckle 332 on the positioning rod 331 is inserted into the angular slot 321 of the horizontal turntable 320 to form a buckling effect of the buckle 332, and there will be no displacement even under the blowing of the roof wind, achieving the purpose of fixing the antenna in the H (horizontal) azimuth.

[0109] In some embodiments of the present application, the lifting member 400 includes:

[0110] A lifting platform 410, on which the horizontal turntable 320 and the first driver 310 are arranged;

[0111] A second driver 420, one end of which is connected to the lifting platform 410 and is used to drive the lifting platform 410 to move up and down;

[0112] The pole base, the other end of the second driver 420 is installed on the pole base, and the pole base is used to be installed on the floor.

[0113] In this embodiment, the horizontal turntable 320 can be installed on the lifting platform 410 by welding or bolt connection or other means. The first driver 310 is installed on the lifting platform 410 by welding or bolt connection or other means. The mounting component 200 can be directly installed on the first driver 310, or the mounting component 200 can be rotatably installed on the lifting platform 410 relative to the lifting platform 410. For example, bearings are provided. The lifting platform 410 has a mounting groove. The outer ring of the bearing is in interference fit with the mounting groove, and the mounting component 200 and the inner ring of the bearing are in interference fit, so that the mounting component 200 can rotate relative to the lifting platform 410.

[0114] The second driver 420 can be an oil cylinder or an electric cylinder. The lifting platform 410 is arranged on the output end of the oil cylinder or the electric cylinder, and the lifting platform 410 is driven to move up and down by the oil cylinder or the electric cylinder. Thus, the lifting platform 410 is driven to move up and down to drive the horizontal turntable 320, the mounting component 200, the antenna, the first driver 310, etc. on the lifting platform 410 to move up and down.

[0115] In some embodiments of the present application, the second driver 420 includes:

[0116] A hydraulic telescopic bracket, one end is connected to the lifting platform 410, the other end is installed on the pole base, and has an oil cavity. The oil cavity is used to drive the lifting platform 410 to rise when hydraulic oil is introduced, and drive the lifting platform 410 to descend when the hydraulic oil is withdrawn;

[0117] An oil pump, communicating with the oil cavity, for introducing the hydraulic oil into the oil cavity or withdrawing the hydraulic oil from the oil cavity.

[0118] In this embodiment, the second driver 420 can also adopt a hydraulic telescopic bracket. The hydraulic telescopic bracket includes an adjustable bracket and an adjustable base, and the adjustable bracket and the adjustable base are connected by a sleeve type. The adjustable base is connected to the pole base, and the pole base is locked on the floor by bolts. The adjustable base has an oil cavity. The first end of the adjustable bracket is inserted into the oil cavity, and the other end is connected to the lifting platform 410 by bolts or welding.

[0119] The STM32 single-chip microcomputer is used to control the solenoid valve and the oil pump to extract and inject hydraulic oil to realize the V (vertical) azimuth adjustment of the antenna. At the same time, the STM32 single-chip microcomputer monitors the change of the weight of the extracted and injected hydraulic oil through the pressure sensor built in the adjusting bracket, and then realizes the control of the height adjustment value. The oil cavity of the adjusting base, the barrel diameter of the oil cavity is D = 180 mm, and the density of the hydraulic oil is δ = 900 kg / m 3, the weight W of the hydraulic oil rising or falling by a height H of 100 mm is W = 2 * π * (D / 2)^2 * H * δ = 4.58 kg. Therefore, it can be known that if it rises by 100 mm, 4.58 kg of hydraulic oil needs to be injected, and if it falls by 100 mm, 4.58 kg of hydraulic oil needs to be pumped out. The specific adjustment mode is to realize the hydraulic lifting operation through the control of the STM32 single-chip microcomputer. When rising is required, the solenoid valve controls the oil pump to press the hydraulic oil into the hydraulic cylinder, thereby pushing the antenna to rise vertically. When falling is required, the solenoid valve controls the oil pump to pump out the hydraulic oil from the hydraulic cylinder, thereby pushing the antenna to fall vertically.

[0120] In some embodiments of the present application, it further includes:

[0121] A lightning rod 500, arranged on the top of the installation component 200.

The antenna is installed on the side of the installation component 200, and the installation component 200 is installed on the rotation orientation component. When the rotation positioning component 300 rotates, it drives the installation component 200 to rotate, so that the antenna rotates with the installation component 200 to achieve the effect of adjusting the antenna angle. The rotation positioning component 300 is arranged on the lifting component 400, and the rotation positioning component 300 and the installation component 200 are driven by the lifting component 400 to rise or fall relative to the floor surface to adjust the rise and fall of the antenna. It effectively solves the technical problem that when the antenna is directly installed using a U-shaped clamp and the receiving angle of the antenna needs to be adjusted, the U-shaped clamp and the antenna need to be disassembled and adjusted to achieve the adjustment of the antenna angle, and the adjustment difficulty is relatively high. It is convenient to adjust the angle and lift of the antenna, so that the antenna can better adjust the receiving signal according to different requirements in terms of angle and height.
