Description
Technical Field
[0001] The present invention belongs to the technical field of antenna components or devices combined with antennas, and in particular relates to a multi-feedback high-precision collaborative control gantry and a collaborative control method thereof. Background Art
[0002] As a necessary medium for communication, the antenna transforms the guided waves propagating on the transmission line into electromagnetic waves propagating in the unbounded medium, or performs the opposite transformation, that is, transmits or receives electromagnetic waves. Whether as a base station or a mobile terminal, the antenna acts as the middleware for transmitting and receiving signals.
[0003] With the country's investment in the communications industry, the communications industry has made great progress in the past few decades. People's demand for communications is increasing, the amount of information processed has increased exponentially, and the key technologies of communications are quietly changing.

[0004] Taking Huawei's 5G AAU active antenna system as an example, it integrates RF and antenna systems, simplifies the antenna surface, improves coverage and capacity, and speeds up network construction. The antenna and equipment that need to be erected are integrated. In fact, the antenna size (length × width × height) will be larger and heavier. Based on this, the coordination and communication requirements faced by 5G AAU in the deployment of traditional rooftop sites are becoming increasingly higher, and it is also easier for the owner to cause obstacles to the construction of new sites during the construction process.

Unless the antenna cover is enlarged again, the space cannot be fully utilized and the deployment requirements of 5G cannot be met, which greatly weakens the practical significance of 5G urban base stations in beautifying communications;
[0007] (2) The antenna cannot be monitored during the adjustment process. Since the use and deployment of antennas involve various fields such as people's livelihood and communication security, if there is improper adjustment or control of the antenna, there may be a large number of safety hazards.

[0046] In the present invention, generally, the rotation range is ±45° and the downward tilt angle can be adjusted within ±15°.
[0047] In the present invention, the controller directly controls the rotation unit and the rotating unit through the first driving unit and the second driving unit, thereby increasing the accuracy and working efficiency of antenna rotation and downtilt angle adjustment.
[0048] In the present invention, a sensor unit is also provided in conjunction with the gantry. The signal fed back by the sensor unit is used to control the rotation speed of the antenna and the downtilt angle adjustment via a controller, thereby ensuring the stability of the antenna in the cover 19 and ensuring that the horizontal lobes of the base station equipment and the antenna are always on the same plane as the cover 19. After one adjustment, the position of the cover 19 is basically fixed, without the need for repeated corrections, thereby greatly reducing the difficulty of operation.
[0049] The present invention completes the adjustment of the antenna in five degrees of freedom as a whole, fully utilizes the internal space of the beautification cover while reducing the volume and floor space of the beautification cover, facilitates the adjustment of the downtilt angle and azimuth angle, meets the deployment requirements of 5G, and is easy to realize the practical significance of 5G communication; the control is safe, the adjustment efficiency is high and the adjustment effect is good, and the needs of collaborative control and adjustment of multiple platforms and multiple operators are met under the premise of ensuring safety.
[0050] The mounting back plate includes a U-shaped mounting plate 4, a vertical plate 6 is vertically provided in the middle of the concave surface of the U-shaped mounting plate 4, and a slide groove 7 is provided at the bottom and top of the vertical plate 6. A slide plate 8 is provided to cooperate with any of the slide grooves 7, and any of the slide plates 8 is hinged with an end positioning block 9 facing away from the middle of the concave surface of the U-shaped mounting plate 4.
[0051] The rotating unit includes two base plates 10 respectively arranged at corresponding heights of the two vertical rods 3, a rotating mounting plate 11 is provided between any of the base plates 10 and the side plate of the corresponding U-shaped mounting plate 4, any of the rotating mounting plates 11 is fixedly arranged with the base plate 10 on the corresponding side, a first rotating shaft hole 12 is cooperated between any of the rotating mounting plates 11 and the side plate of the corresponding U-shaped mounting plate 4, and the first rotating shaft holes 12 on both sides are arranged correspondingly; the upper part of one of the rotating mounting plates 11 is cooperated with the motor mounting plate 14 through the second rotating shaft hole 13, the second driving unit includes a first motor 15 arranged on the back side of the motor mounting plate 14, the output end of the first motor 15 is threadedly connected to the screw hole at the top of the bracket 16, and the bracket 16 is fixedly arranged on the back side of the U-shaped mounting plate 4.
[0052] In the present invention, in order to reduce the difficulty of the mounting back plate driving the antenna to adjust the downtilt angle, the antenna is not directly mounted on the mounting back plate, but by setting a vertical plate 6 in the middle of the mounting back plate, the vertical plate 6 is fitted to the back of the antenna, and a slide plate 8 is set in conjunction with a slide groove 7, so that antennas of different lengths can be adapted.
[0053] In the present invention, obviously, different mounting holes 17 are provided on the vertical plate 6 and the slide plate 8 to fix the antenna. In order to further ensure the stability of the antenna fixation, the upper and lower ends of the antenna are limited by hinged end positioning blocks 9.
[0054] In the present invention, the rotating unit uses two substrates 10 as fixed plates and is fixedly connected to the vertical rod 3 on the corresponding side. After the two side plates of the U-shaped mounting plate 4 are coaxially rotatably connected to the rotating mounting plate 11 on the corresponding side, the rotating mounting plate 11 on the corresponding side is fixedly set with the substrate 10 on the corresponding side, and a motor mounting plate 14 is coaxially rotatably connected to one of the rotating mounting plates 11, and generally the motor mounting plate 14 is set above the U-shaped mounting plate 4, so that when the first motor 15 serving as the second driving unit is output, its output end moves relative to the bracket 16 on the back side of the U-shaped mounting plate 4, such as through the screw 35 at the output end of the first motor 15 and the screw hole at the top of the bracket 16, the relative distance between the first motor 15 and the bracket 16 is adjusted in a threaded connection manner, and then the bracket 16 acts on the U-shaped mounting plate 4, so that the U-shaped mounting plate 4 and the motor mounting plate 14 respectively rotate around the axis between the rotating mounting plate 11, so as to achieve the purpose of adjusting the antenna downtilt angle.
[0055] In the present invention, arc-shaped through holes 18 may be correspondingly provided between the rotating mounting plate 11 , the U-shaped mounting plate 4 and the motor mounting plate 14 to further adapt the rotating mounting plate 11 , the U-shaped mounting plate 4 and the motor mounting plate 14 .
[0056] In the present invention, since the downtilt angle of the antenna is limited, the antenna can also be limited by a rotating limit block.
[0057] The rotating unit includes a rotating shaft 5 that cooperates with the first driving unit. The top of the rotating shaft 5 passes through the rotating disk 2 and is higher than the rotating disk 2. A first sleeve 20 is fixed outside the rotating shaft 5 on the rotating disk 2, and the bottom of the first sleeve 20 is fixed on the rotating disk 2. A second sleeve 21 is provided outside the rotating shaft 5 at the bottom of the mounting surface of the frame 1, and a bearing 22 is provided between the second sleeve 21 and the rotating shaft 5. The top of the second sleeve 21 is fixed to the bottom of the mounting surface of the frame 1, and the first driving unit is arranged in cooperation with the second sleeve 21.
[0058] The first drive unit includes a second motor 24 that is arranged in cooperation with the controller, and the output end of the second motor 24 is arranged in cooperation with the worm wheel 28 at the bottom of the rotating shaft 5 through a worm 27; the second drive unit also includes a wheel 29, and the axis of the wheel 29 is connected to the end of the worm 27 that is away from the second motor 24; the worm 27 is arranged horizontally through the second sleeve 21.
[0059] In the present invention, the top and bottom of the rotating disk 2 are respectively provided with a first sleeve 20 and a second sleeve 21, so that the rotating disk 2 can rotate while the frame 1 is fixed while the rotating disk 2 rotates while the first driving unit is controlled by the controller to drive the rotating shaft 5 to rotate and then the rotating disk 2 rotates around the central axis.
[0060] In the present invention, the second motor 24 is used as the drive. When the second motor 24 is working, the worm 27 rotates, driving the worm wheel 28 and the rotating shaft 5 to rotate together. The rotating shaft 5 cooperates with the bearing 22 in the inner cavity of the second sleeve 21. The frame 1 itself does not move. The rotating shaft 5 is directly fixed to the first sleeve 20, and the first sleeve 20 is fixed to the rotating disk 2. Therefore, the rotating shaft 5 drives the rotating disk 2 to rotate, and then drives all the mechanisms on the rotating disk 2 to rotate around the axis.
[0061] In the present invention, in order to display the adjusted angle and ensure its adjustability, a scale plate 23 may be provided on the rotating disk 2 corresponding to the top of the rotating shaft 5 for indicating the angle.
[0062] In the present invention, in order to ensure that the rotation angle and the downward tilt angle of the antenna are properly controlled, a wheel 29 is provided coaxially with the second motor 24 (worm 27) on the opposite side of the second motor 24. When the adjustment of the second motor 24 fails or there is a deviation value, the wheel 29 is used for further fine-tuning. At this time, the angle can also be indicated by the dial 23. Of course, in order to maintain the safety of the antenna, under normal circumstances, the second motor 24 and the wheel 29 are both in a locked state.
[0063] In the present invention, since the rotation angle of the antenna is limited, a limit column 30 or a limit sensor can be arranged between the rotating disk 2 and the top surface of the frame 1 to output the limit or limit signal. This is easy for technical personnel in the field to understand, and technical personnel in the field can set it according to their needs.
[0064] In the present invention, in order to achieve relative independence in adjusting the rotation angle and downtilt angle of the antenna, the controller uses two stepper motors to control the rotating shaft 5 and the rotating unit respectively. In fact, the rotation angle and downtilt angle of the antenna can be controlled by the step amount of the stepper motor.
[0065] In the present invention, the motor rotates in the form of angle pulse drive and the pulses are subdivided, the rotation accuracy is high, and a worm gear is used as a transmission mechanism, which has the advantages of a large transmission speed ratio and a single-phase drive function, and has a self-locking function for the transmission mechanism and the workpiece.
[0066] The sensing unit includes a temperature sensor disposed in the cover 19, a first weight sensor 25 disposed at the mounting back plate, and a second weight sensor 26 disposed at the rotating disk 2; a cooling mechanism is disposed upward from the bottom of the frame 1 to cooperate with the temperature sensor.
[0067] In the present invention, in order to achieve the purpose of multi-feedback, the rotation angle and the downward tilt angle of the antenna in the gantry can be precisely adjusted through the cooperation of the temperature sensor, the weight sensor, etc.
[0068] In the present invention, a temperature sensor is used to detect the temperature inside the cover 19 to further improve the heat exchange capacity. When the measured temperature is too high, an alarm can be issued, or a cooling mechanism such as an exhaust fan, an air conditioning module and other equipment arranged upward from the bottom of the frame 1 can be used to assist in heat dissipation and cooling.
[0069] In the present invention, the first weight sensor 25 installed at the mounting back plate is used to feed back the antenna weight, and the optimal downtilt angle adjustment speed is calculated based on the antenna weight. Similarly, the second weight sensor 26 is used to feed back the weight of the entire mechanism on the rotating disk 2, and then the optimal antenna angle adjustment speed is calculated.
[0070] In the present invention, it is obvious that ventilation holes 34 are provided on the mounting surface of the frame 1, the rotating disk 2 and the cover 19, so as to dissipate heat to the maximum extent without affecting the structural strength, thereby ensuring the service life and performance of the antenna installed on the gantry.
[0071] A reinforcing rod 31 is disposed transversely between the two vertical rods 3 , and a first supporting column 32 and a second supporting column 33 are disposed between the reinforcing rod 31 and the rotating disk 2 with the axis of the rotating disk 2 as a symmetric point.
[0072] In the present invention, in order to ensure the strength of the vertical rod 3, a reinforcing rod 31 is arranged between the vertical rods 3, generally at the lower part of the vertical rod 3, to reinforce the vertical rod 3 in the horizontal direction. At the same time, a first support column 32 and a second support column 33 are respectively arranged on the front end face and the rear end face of the reinforcing rod 31. The first support column 32, the second support column 33 and the two vertical rods 3 are respectively supported at the 90° position of the rotating disk 2, with high and uniform strength, thereby ensuring the axial strength of the entire gantry.
[0073] The present invention also relates to a collaborative control method using the multi-feedback high-precision collaborative control gantry to solve the real-time and effectiveness of the horizontal azimuth and downtilt angles of base station equipment (AAU) or antennas in daily mobile communication network optimization work, thereby freeing up the work tasks of base station maintenance personnel; through multi-feedback high-precision collaborative control means, the feasibility and adjustable value of antenna adjustment are confirmed by encrypted operations between the user end and the control end, and under the premise of ensuring the adjustment amount, the antenna adjustment value and adjustment means are set to the best through data simulation of multiple feedback channels, and all adjustment data are synchronized to all queryable users, thereby ensuring the feasibility of collaborative operation control.
[0074] The method comprises the following steps.
[0075] Step 1: Install the antenna on the mounting back plate, the antenna is in a vertical and non-rotating state; install the cover 19; initialize the gantry controller to obtain the weight of the antenna and the weight of the entire mechanism on the rotating disk 2.
[0076] Step 2: Determine whether the cover 19 satisfies the requirement that the horizontal lobes of the base station equipment and the antenna are on the same plane as the cover 19. If so, fix the cover 19 and proceed to the next step. Otherwise, adjust the position of the cover 19 and repeat step 2.
[0077] In the present invention, when the cover 19 satisfies the requirement that the horizontal lobes of the base station equipment and the antenna are on the same plane as the cover 19, the antenna and the cover 19 are in an optimal state, which needs to be maintained in subsequent adjustments.
[0078] Step 3: The user sends a control request, the controller assigns a secret key to the legal user's smart terminal, and the user logs in with the secret key.
[0079] The step 3 comprises the following steps:
[0080] Step 3.1: The user sends a control request, and the user end encrypts the control request in an independent encryption mode between the controller and the user;
[0081] Step 3.2: The encrypted control request information is transmitted to the controller, and the controller verifies the IP address that transmits the control request information; if the IP address is in the whitelist, proceed directly to step 3.4, otherwise, proceed to the next step;
[0082] Step 3.3: Determine whether the IP address is safe. If so, proceed to the next step. Otherwise, discard the control request information and feedback a rejection code.
[0083] Step 3.4: The controller distributes the secret key to the smart client of the current user;
[0084] Step 3.5: The user logs in with the secret key. After the controller confirms that it is correct, it decrypts the control request in an independent encryption mode between the controller and the user to obtain the control request.
[0085] In the present invention, in the case of multi-party collaborative control, the user end is likely to be hijacked, so it should not be hastily logged in for verification, but its credibility should be confirmed first.
[0086] In the present invention, users can directly make control requests, which include but are not limited to the antenna angle and / or downtilt angle that need to be adjusted, and user basic information; there is an independent encryption mode between each user and the controller, which is different for each user in principle, ensuring the uniqueness and non-hijackability of the encryption.
[0087] In the present invention, after receiving the control request, the controller verifies the IP address of the user terminal. Only when the user terminal verifies accurately will the secret key be allocated to the user terminal. The secret key is randomly allocated to facilitate user management and avoid leakage. When the user logs in with the secret key, the controller will decrypt the control request only after confirming that it is correct.
[0088] In the present invention, the user's login involves a second confirmation, which has a high security factor and is not easily stolen by hackers.
[0089] Step 4: Enter the antenna rotation angle and / or downtilt angle that needs to be adjusted, and calculate the optimal antenna rotation angle and / or downtilt angle based on the user performance indicators of the current base station equipment and the antenna coverage area. If it is within the range of the antenna rotation angle and / or downtilt angle that needs to be adjusted, set the adjustment value to the optimal antenna rotation angle and / or downtilt angle; otherwise, set the adjustment value to the antenna rotation angle and / or downtilt angle that needs to be adjusted; proceed to the next step.
[0090] In the present invention, the calculation of the optimal antenna rotation angle and / or downtilt angle can be set by a person skilled in the art based on the needs. Here is an embodiment:
[0091] (a) Using existing standard MRO data and GN port data, an indicator model for resident users is established from the perspectives of wireless and data perception;
[0092] Among them, standard MRO data includes: downlink coverage, to obtain the proportion of users with weak downlink coverage; uplink quality, to obtain the proportion of users with poor uplink SINR; indoor distribution ratio, to obtain the proportion of indoor distribution traffic; switching performance, to obtain the ping-pong switching performance of users;
[0093] Among them, the GN port data includes: page access success rate, to obtain the user-level page access success rate; page download speed, to obtain the user page download speed; page response delay, to obtain the user page response delay; video category to obtain video freeze and success rate; VOLTE to obtain user voice success rate and MOS;
[0094] (b) Conducting qualitative judgment on hidden problems, such as screening poor-quality users. For example, taking the data of downlink coverage and uplink quality as an example, users with a downlink coverage less than -110dBm accounting for 10% to 30% are generally poor-coverage users, users with an uplink sinr <-1 accounting for 10% to 30% are generally poor-uplink quality users, users with a downlink coverage less than -110dBm accounting for 30% to 50% are moderately poor-coverage users, users with an uplink sinr <-1 accounting for 30% to 50% are moderately poor-uplink quality users, users with a downlink coverage less than -110dBm accounting for >50% are severely poor-coverage users, and users with an uplink sinr <-1 accounting for >50% are severely poor-uplink quality users. When the proportion of poor-quality users is >10%, the cell is considered to be a poor-quality cell. Specifically, the proportion of poor-quality users is used to divide the cell into generally poor-quality cells, moderately poor-quality cells, and severely poor-quality cells.
[0095] (c) Establish feature points and their coverage attributes, associate the original MR data with the feature library, and identify hidden problem areas;
[0096] (d) Make step-by-step adjustments to the antenna rotation angle and / or downtilt angle based on the hidden problem area.
[0097] Step 5: Obtain the readings of the first weight sensor 25 and / or the second weight sensor 26, calculate the moment of inertia of the antenna rotating around the first rotation axis in the first rotation axis hole 12 and / or the moment of inertia of the entire mechanism on the gantry rotating around the rotation axis 5, and calculate the optimal angular velocity of the antenna rotation and / or downward tilt based on the moment of inertia.
[0098] In the present invention, the position of the antenna can be fixed by installing the back plate. At this time, the gantry as a whole can be regarded as a uniform column, and the antenna relative to the installation back plate can also be regarded as a uniform column. Therefore, according to the rotational kinetic energy Ek=1 / 2J ω 2 , based on the conservation of angular momentum, the torque M=Ja , a is the angular acceleration. By integrating the angular acceleration over time, we can get the angular velocity.
[0099] Step 6: The controller packages the modified values and sends them to the superior for approval. If approved, proceed to the next step; otherwise, return to step 4.
[0100] In the present invention, the modified data needs to be confirmed for a third time to ensure that it can be modified.
[0101] Step 7: The controller controls the first driving unit and / or the second driving unit to drive the rotating shaft 5 and / or the first rotating shaft, and the rotating shaft 5 and / or the first rotating shaft runs at an optimal angular velocity until moving to an optimal antenna rotation angle and / or downtilt angle.
[0102] Step 8: Feedback a confirmation code to the user who issued the control request, and synchronize the antenna rotation and / or downtilt angle and related information to the LAN platform.
[0103] In the present invention, all modified data are synchronized to the local area network platform as part of collaborative control and become the basic data for the next modification.
[0104] During the operation of the antenna, the temperature sensor obtains the temperature inside the cover 19 in real time. When the temperature exceeds 30°C, the cooling mechanism is turned on. When the temperature drops below 25°C, the cooling mechanism is turned off.
[0105] During the operation of the antenna, it is determined in real time whether the cover 19 satisfies the requirement that the horizontal lobes of the base station equipment and the antenna are in the same plane as the cover 19. If so, the operation continues; otherwise, an alarm is sounded.
[0106] In the present invention, the changes in the indicators before and after the antenna beautification and cover 19, such as voltage standing wave ratio, isolation, horizontal plane half-power angle, front-to-back ratio, cross-polarization ratio (axial), cross-polarization ratio (±60°), wave transmission performance, third-order intermodulation and upper sidelobe suppression (dB), etc., do not exceed the allowable deviation range.
[0107] In the present invention, the action response time of the device is: during the adjustment process of the azimuth angle of 0° to 45°, the whole action time is 27.4 seconds; during the adjustment process of the downtilt angle of 0° to 15°, the whole action time is 46.9 seconds.
[0108] The present invention arranges a rotating disk 2 on a frame 1, and controls the rotating disk 2 with a rotating unit to drive two vertical rods 3 on the top, a mounting back plate between the two vertical rods 3, and an outer cover 19 to rotate the antenna around the rotation axis, and drives the mounting back plate to adjust the downtilt angle of the antenna with the rotating unit, and controls the rotation unit and the rotating unit directly through the first driving unit and the second driving unit, thereby increasing the accuracy and work efficiency of the antenna rotation and downtilt angle adjustment; at the same time, a sensor unit is also arranged in conjunction with the gantry, and the speed of the antenna rotation and downtilt angle adjustment is controlled by the controller through the signal fed back by the sensor unit, thereby ensuring the stability of the antenna in the cover 19 and ensuring that the horizontal lobes of the base station equipment and the antenna are always on the same plane as the cover 19.
[0109] The present invention further adds a multi-feedback high-precision collaborative control method, and uses encrypted operations between the user end and the control end to confirm the feasibility and adjustable value of antenna adjustment. Under the premise of ensuring the adjustment amount, the antenna adjustment value and adjustment method are set to the best through data simulation of multiple feedback channels. All adjustment data are synchronized to all queryable users, ensuring the feasibility of collaborative operation control.
[0110] The present invention completes the adjustment of the antenna in five degrees of freedom as a whole, fully utilizes the internal space of the beautification cover while reducing the volume and floor space of the beautification cover, facilitates the adjustment of the downtilt angle and azimuth angle, meets the deployment requirements of 5G, and is easy to realize the practical significance of 5G communication; the control is safe, the adjustment efficiency is high and the adjustment effect is good, and the needs of collaborative control and adjustment of multiple platforms and multiple operators are met under the premise of ensuring safety.
