Description

Technical Field

[0001] The present invention relates to the field of beamforming technology, and in particular to a beamforming device and method. Background Art

[0002] Beamforming is a method of processing the output of each element of a multi-element array arranged in a certain geometric shape (such as weighting, delay, summation, etc.) to form spatial directivity. Beamforming technology is mainly used for fully digital ultrasonic imaging, and beam focusing is achieved through digital delay compensation, thereby improving image quality. It includes two parts: transmitting and receiving. Using digital delay instead of analog delay can achieve accurate delay compensation and point-by-point tracking dynamic focusing, while facilitating the realization of dynamic aperture and dynamic track control, overcoming many shortcomings of analog delay. Beamforming technology was first used in electronic countermeasures, phased array radar, sonar and other communication equipment in the 1960s. Adaptive array interference nulling technology based on digital beamforming (DBF) can improve the anti-interference ability of radar systems and is a key technology for the new generation of military radars. In positioning communication systems, beamforming obtains sound field information through microphone arrays, processes signals, determines the direction of the signal wave, and thus accurately directs the source.

[0003] However, this patent still has certain shortcomings when used. The multi-antenna array is one of the core components of beamforming technology. The multi-antenna array consists of multiple antenna elements, each of which can independently control its phase and amplitude. By adjusting the phase and amplitude, a beam pointing in a specific direction can be dynamically formed. The antenna elements include antenna signal receiving elements. During the use of existing antenna signal receiving elements, manual adjustment of the direction and elevation of signal reception is required to make the received signal strength reach the strongest, but manual adjustment is very time-consuming and inefficient. When adjusting multiple antenna elements, if manual adjustment is used, huge manpower and material resources are required. At the same time, when manual adjustment is performed, the control of the angle and direction is generally roughly estimated, with low accuracy and low efficiency. Summary of the invention

[0004] The object of the present invention is to provide a beamforming device and method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A beamforming device and method, comprising a base, a mounting hole is provided on the side of the base, a rotating assembly is provided on the top of the base, the rotating assembly comprises an upper cover located on the top of the base, a positioning column and a limit frame are provided at the bottom of the upper cover, an abutment groove is provided on the side of the limit frame, a card groove is provided through the abutment groove, a rotating groove is provided at the center of the upper cover, a rotating member is rotatably connected in the rotating groove, a connecting member is fixedly connected to the bottom of the rotating member, an antenna element is provided on the top of the rotating member, a waterproof coating is provided on the outside of the antenna element, a lightning protection element and a surge protector are provided on the signal receiver of the antenna element, and a second rotating seat and a third rotating seat are respectively fixedly connected to the bottom of the antenna element.

[0008] As a preferred solution of the present invention, a movable cavity is provided inside the base, a fixing component is arranged inside the movable cavity, and the fixing component includes a sliding rod slidably connected to the inside of the movable cavity.

[0009] As a preferred solution of the present invention, a fixing bar is fixedly connected to one side of the slide bar, a pulling block is fixedly connected to the side of the fixing bar, and an abutting block is fixedly connected to the other side of the slide bar.

[0010] As a preferred solution of the present invention, a clamping block is provided on the side of the abutting block, the clamping block is plugged into the clamping slot, and the abutting block is abutted against the abutting slot.

[0011] As a preferred solution of the present invention, a spring is arranged outside the sliding rod, one end of the spring is elastically connected to the inner wall of the moving cavity, and the other end of the spring is elastically connected to the side of the abutment block.

[0012] As a preferred solution of the present invention, a second positioning groove is provided on the top of the base, the second positioning groove and the positioning column are plugged in, the interior of the base is configured as an inner cavity, and a threaded groove and a first positioning groove are provided on the bottom of the inner cavity.

[0013] As a preferred solution of the present invention, a driving motor is arranged in the first positioning groove, an output end is arranged on the top of the driving motor, and the output end is clamped with the bottom of the connecting piece.

[0014] As a preferred solution of the present invention, a mounting plate is provided on the outside of the driving motor, and the mounting plate is threadedly connected via a fixing screw and a thread groove.

[0015] As a preferred solution of the present invention, a beamforming method comprises the following steps:

[0016] Step 1: First, the geometric structure of the multi-beam array needs to be accurately constructed, including the number, arrangement, spacing and other parameters of the array elements. When designing a multi-antenna array, multiple factors need to be considered, including the number, arrangement, spacing and operating frequency of antennas. The more antennas there are, the finer the beams formed, but this will also increase the complexity and cost of the system.

[0017] Step 2: Arrange multiple signal antenna receiving devices according to the designed multi-beam array, and then adjust the elevation angle and direction of the antenna element as needed. First, turn on the control switch of the drive motor. Since the output end of the drive motor is connected to the bottom of the connector, when the output end of the drive motor rotates, the connector also rotates with the output end, thereby driving the rotating part to rotate, thereby realizing the horizontal rotation of the antenna element. Then, the hydraulic rod is controlled to extend or contract to rotate the antenna element, thereby realizing the adjustment of the elevation angle of the antenna element.

[0018] Step 3: The antenna element then changes the shape and direction of the directional pattern by controlling the feed phase of the radiating elements in the array, using DSP technology to change the signal phase of each antenna port differently to form a beam that best suits a specific direction;

[0019] Step 4: Use digital beamforming (DBF), adaptive beamforming and other technologies to flexibly adjust the beam direction, width and gain according to different targets and environmental conditions;

[0020] Step 5: Calculate the key performance indicators of the multi-beam phased array, such as beam pointing accuracy, sidelobe level, signal-to-noise ratio, etc., and evaluate the performance of the system by comparing the results of different parameter settings and algorithms;

[0021] Step 6: Send and receive signals through multiple antennas to improve the data transmission rate and reliability of the communication system. The base station receives signals from users through multiple antennas. After that, the base station will merge and process these received signals to improve the communication quality. Finally, the merged signal will be further processed to restore the original sent data, so that the data sent by the user can be accurately restored, thus completing the communication process.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, a base structure of an antenna assembly that is convenient for disassembly and assembly is formed by setting a base, a rotating assembly and a fixed assembly, etc. When it is necessary to inspect and maintain the components inside the base, the pull blocks on both sides are pulled so that the pull blocks drive the fixing bar, the sliding rod and the abutting block to move sideways until the abutting block and the clamping block are no longer abutted with the abutting groove and the clamping groove, and then the upper cover is moved upward to achieve separation of the upper cover and the base. When it is necessary to adjust the elevation angle and direction of the antenna assembly, the control switch of the driving motor is first turned on. Since the output end of the driving motor is clamped with the bottom of the connecting member, when the output end of the driving motor rotates, the connecting member also rotates with the output end, thereby driving the rotating member to rotate, thereby realizing horizontal rotation of the antenna element. Then, the hydraulic rod is controlled to extend or contract, so that the antenna element is rotated, thereby realizing adjustment of the elevation angle of the antenna element. By setting the antenna signal receiving element, the antenna assembly can find a suitable direction and elevation angle, thereby ensuring the strength and stability of the signal, thereby providing a better receiving experience, and thereby ensuring the stability of the signal receiving process.

[0024] 2. In the present invention, by combining beamforming with multiple-input multiple-output (MIMO) technology, by using an antenna array composed of a large number of antennas and combining MIMO technology, the satellite communication system can provide services to more users on the same spectrum resources, thereby improving the capacity and coverage of the system. The multi-array antenna technology uses an array composed of multiple antennas, beamforming and spatial multiplexing, etc. to accurately point to each user device, reduce interference, and improve signal quality, thereby expanding the coverage while ensuring communication quality, especially in marginal areas and inside high-rise buildings. MIMO technology uses multiple antennas at the transmitting and receiving ends to achieve spatial multiplexing and diversity of signals, significantly improving the performance of the communication system. The MIMO system can provide independent, almost interference-free service channels for multiple users on the same time-frequency resources, greatly increasing the system capacity.

[0036] Among them, by providing the base 1, the rotating component 3 and the fixing component 11, etc., a base structure of the antenna component 10 that is convenient for disassembly and assembly is formed. When it is necessary to inspect and maintain the components inside the base 1, the pull blocks 1102 on both sides are pulled, so that the pull blocks 1102 drive the fixing strip 1101, the sliding rod 1103 and the abutting block 1105 to move sideways until the abutting block 1105 and the clamping block 1106 are no longer abutted against the abutting groove 304 and the clamping groove 305, and then the upper cover 301 is moved upward to separate the upper cover 301 and the base 1. When it is necessary to adjust the elevation angle and direction of the antenna component 10, the control switch of the driving motor 15 is turned on first. Since the output terminal 16 at the top of the driving motor 15 is clamped with the bottom of the connecting member 308, when the output terminal 16 of the driving motor 15 rotates, the connecting member 308 also follows the output terminal 16 The rotating member 307 is rotated to rotate, thereby realizing the horizontal rotation of the antenna element 10.

[0038] A beamforming method comprises the following steps:

[0039] Step 1: First, the geometric structure of the multi-beam array needs to be accurately constructed, including the number, arrangement, spacing and other parameters of the array elements. When designing a multi-antenna array, multiple factors need to be considered, including the number, arrangement, spacing and operating frequency of antennas. The more antennas there are, the finer the beams formed, but this will also increase the complexity and cost of the system.

[0040] Step 2: Arrange multiple signal antenna receiving devices according to the designed multi-beam array, and then adjust the elevation angle and direction of the antenna element 10 as needed. First, turn on the control switch of the drive motor 15. Since the output terminal 16 at the top of the drive motor 15 is clamped with the bottom of the connecting member 308, when the output terminal 16 of the drive motor 15 rotates, the connecting member 308 also rotates with the output terminal 16, thereby driving the rotating member 307 to rotate, thereby realizing the horizontal rotation of the antenna element 10. Then, the hydraulic rod 6 is controlled to extend or contract, so that the antenna element 10 rotates, thereby realizing the adjustment of the elevation angle of the antenna element 10;

[0041] Step 3: The antenna element 10 then changes the shape and direction of the directional pattern by controlling the feeding phase of the radiating elements in the array, and uses DSP technology to differently change the signal phase of each antenna port to form a beam that best suits a specific direction;

[0042] Step 4: Use digital beamforming (DBF), adaptive beamforming and other technologies to flexibly adjust the beam direction, width and gain according to different targets and environmental conditions;

[0043] Step 5: Calculate the key performance indicators of the multi-beam phased array, such as beam pointing accuracy, sidelobe level, signal-to-noise ratio, etc., and evaluate the performance of the system by comparing the results of different parameter settings and algorithms;

[0044] Step 6: Send and receive signals through multiple antennas to improve the data transmission rate and reliability of the communication system. The base station receives signals from users through multiple antennas. After that, the base station will merge and process these received signals to improve the communication quality. Finally, the merged signal will be further processed to restore the original sent data, so that the data sent by the user can be accurately restored, thus completing the communication process.

[0045] Among them, by combining beamforming with multiple-input multiple-output (MIMO) technology, by using an antenna array composed of a large number of antennas and combining MIMO technology, the satellite communication system can provide services to more users on the same spectrum resources, thereby improving the capacity and coverage of the system. Multi-array antenna technology uses an array composed of multiple antennas, beamforming and spatial multiplexing, etc., to accurately point to each user device, reduce interference, and improve signal quality, thereby expanding coverage while ensuring communication quality, especially in marginal areas and inside high-rise buildings. MIMO technology uses multiple antennas at the transmitting and receiving ends to achieve spatial multiplexing and diversity of signals, significantly improving the performance of the communication system. The MIMO system can provide independent and almost interference-free service channels for multiple users on the same time-frequency resources, greatly increasing the system capacity.

[0046] Working process of the present invention: When a beamforming device and method designed by the present invention is in operation, when it is necessary to inspect and maintain the components inside the base 1, the pull blocks 1102 on both sides are pulled so that the pull blocks 1102 drive the fixing bar 1101, the sliding rod 1103 and the abutment block 1105 to move sideways until the abutment block 1105 and the clamping block 1106 are no longer in abutment with the abutment groove 304 and the clamping groove 305, and then the upper cover 301 is moved upward to separate the upper cover 301 from the base 1. When it is necessary to adjust the elevation angle and direction of the antenna assembly 10, the control switch of the drive motor 15 is first turned on. Since the output terminal 16 at the top of the drive motor 15 and the connector are The bottom of 308 is snap-fitted, so when the output end 16 of the driving motor 15 rotates, the connecting piece 308 also rotates with the output end 16, thereby driving the rotating piece 307 to rotate, and then realizing the horizontal rotation of the antenna element 10, and then the hydraulic rod 6 is controlled to extend or contract to rotate the antenna element 10, so as to adjust the elevation angle of the antenna element 10. By combining beamforming with multiple-input multiple-output (MIMO) technology, by utilizing an antenna array composed of a large number of antennas and combining MIMO technology, the satellite communication system can provide services to more users on the same spectrum resources, thereby improving the capacity and coverage of the system.
