Description

Technical Field

[0001] The invention belongs to the technical field of communication testing, and more specifically, relates to a testing turntable and a testing system having the same. Background Art

[0002] 5G (5th Generation Mobile Communication Technology) communication technology, with its ability to achieve higher data transmission rates in higher frequency bands, is becoming a strong support for wireless data services for traditional mobile terminals such as mobile phones, drones, autonomous driving, virtual reality and other technologies.

[0003] In related technologies, 5G base stations use beamforming technology to support large-scale antenna arrays and configure a large number of antennas, thereby ensuring high-quality transmission of 5G signals. Figure 1 As shown, the base station must use multiple beams with different directions to fully cover the service area such as a cell. During the signal transmission process, the base station uses beams with different directions to transmit wireless signals in turn. This process is called beam scanning (BeamSweeping). At the same time, the user terminal measures the wireless signals emitted by different beams and reports relevant information to the base station (BeamReporting). The base station then determines the best transmission beam aimed at the user based on the user terminal report, thereby obtaining the optimal signal transmission path.

[0004] As a result, since the functions of 5G base stations have changed greatly compared to previous base stations, traditional test turntables cannot perform connectivity tests on 5G base stations involving beam scanning and sector switching, and cannot meet the performance testing requirements of 5G base stations.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figures 1 to 7 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] References to "one embodiment", "some embodiments" or "an embodiment" described in the present specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present invention. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc., appearing at different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0042] In the related technology, for traditional 2G, 3G or 4G base stations, since the antenna and RRU (Radio Remote Unite) are separated from each other and connected by a radio frequency cable, the antenna and RRU are relatively independent and their performance does not affect each other. Their respective performances can be tested through independent tests. For example, the radiation performance test of the antenna can be completed in a microwave darkroom through the far field or near field method, and the RF indicators of the RRU can be measured in the laboratory through conduction. In this way, when using the test system of the traditional base station to test the 5G base station, the active antenna system needs to be split into two parts: the passive antenna array and the RRU for antenna radiation performance testing and RF conduction testing respectively.

[0043] However, for 5G base stations, since the antenna is integrated with the RRU, interference factors such as electromagnetic coupling and active standing waves cannot be completely eliminated. In addition, since the calibration and amplitude-phase weighting of active antennas are completed through a series of active devices on each RF channel, it is very different from the way that passive antenna arrays perform amplitude-phase weighting through passive power division networks. Therefore, for 5G base stations that use large-scale MIMO (Multiple Input Multiple Output) active antenna technology, an integrated OTA test method can effectively reflect its performance indicators, especially for millimeter wave bands. Due to the higher frequency band and smaller device size, its electromagnetic interference problem is more prominent, and the difficulty of splitting it for testing will be further increased, and the test effectiveness and efficiency are difficult to guarantee.

[0044] Based on this, the present invention provides a test turntable, such as Figures 2 to 7 As shown, the test turntable is applicable but not limited to being used for performance testing of base stations, and is particularly suitable for integrated OTA testing of 5G base stations. The test turntable of the present application is specifically described below in conjunction with specific embodiments.

[0045] like Figure 2 and Figure 3As shown, one embodiment of the present invention provides a test turntable, which includes a base 10 and a mounting seat 20. The base 10 is equipped with a horizontal rotation mechanism 11, the mounting seat 20 is installed on the base 10 and connected to the output end of the horizontal rotation mechanism 11, and the horizontal rotation mechanism 11 is used to drive the mounting seat 20 to rotate horizontally relative to the base 10. In this embodiment, the test turntable also includes a plurality of object bearing platforms 30 to be tested, the object bearing platforms 30 to be tested are used to install the object to be tested 100 to be tested for performance, and the mounting seat 20 is provided with a vertical driving mechanism 21. The plurality of object bearing platforms 30 to be tested are movably installed on the mounting seat 20 and arranged around the rotation axis of the mounting seat 20. The output end of the vertical driving mechanism 21 is connected to the plurality of object bearing platforms 30 to drive the object bearing platforms 30 to move vertically relative to the mounting seat 20, thereby adjusting and changing the setting height of each object bearing platform 30 in the vertical direction. The object under test 100 may be a base station under test, but is not limited to a base station under test. Any object that can be tested using the test turntable in this embodiment should be covered within the protection scope of this application.

[0046] In addition, the test turntable also includes a pitch drive assembly 40, which is installed at the output end of the vertical drive mechanism 21, and the output end of the pitch drive assembly 40 is connected to multiple object carriers 30 to drive the object carriers 30 to perform pitch motion, thereby adjusting the pitch angle of each object carrier 30.

[0047] The test turntable provided by the embodiment of the present invention, when in use, installs a plurality of objects to be tested 100 such as base stations to be tested on a plurality of object to be tested bearing platforms 30. The vertical drive mechanism 21 drives the object to be tested bearing platform 30 to move back and forth in the vertical direction, and adjusts and changes the vertical height position of the object to be tested 100; the horizontal rotation mechanism 11 drives the mounting seat 20 to rotate, thereby adjusting and changing the horizontal position of the object to be tested 100 installed on the object to be tested bearing platform 30, that is, changing the azimuth angle of the object to be tested 100; the pitch drive assembly 40 drives and adjusts the pitch angle of each object to be tested bearing platform 30. In this way, the horizontal rotation mechanism 11, the vertical drive mechanism 21 and the pitch drive assembly 40 cooperate with each other, so that the object to be tested 100 installed on the object to be tested bearing platform 30 can achieve three-dimensional posture adjustment. During the test process, the three-dimensional posture of the object to be tested 100 is adjusted accordingly according to the test requirements, thereby completing the performance test of the object to be tested 100.

[0048] More importantly, if Figure 2 and Figure 3As shown, the test turntable of this embodiment is provided with a plurality of object-to-be-tested bearing platforms 30 around the rotation axis of the mounting seat 20. When the object to be tested 100 is a base station to be tested, the plurality of base stations to be tested used simultaneously are installed one by one on each object-to-be-tested bearing platform 30 for testing according to the actual use situation. In this way, the plurality of base stations to be tested can form a set of complete sectors in correspondence during the test, which is equivalent to simulating the actual installation scenario of the base station in a service area such as a cell, and the plurality of base stations to be tested can realize synchronous position movement and three-dimensional posture adjustment during the test process, that is, it simulates the changes in the connection performance involving beam scanning and sector switching when wireless signals are transmitted between the terminal and the base station during actual use, thereby meeting the requirements of integrated testing of 5G base stations (such as integrated OTA testing, etc.), obtaining test data that can more effectively reflect the performance indicators of the base station to be tested, and the test results are more valuable for reference.

[0049] In another embodiment of the present invention, Figure 2 As shown, the above-mentioned test turntable may also include a horizontal track 50 and a horizontal displacement mechanism 60. The horizontal track 50 is horizontally arranged, the rotation axis of the mounting seat 20 is perpendicular to the horizontal track 50, the base 10 is slidably mounted on the horizontal track 50, and the horizontal displacement mechanism 60 is drivingly connected with the base 10 to drive the base 10 to move horizontally along the horizontal track 50. That is, the horizontal displacement mechanism 60 is arranged to drive the base 10 to move along the horizontal track 50, so as to adjust the horizontal position of the object bearing platform 30 in the horizontal direction. When the position of the object 100 to be tested needs to be adjusted in the horizontal direction, the horizontal displacement mechanism 60 is started to drive the base 10 and its upper structure to move along the horizontal track 50.

[0050] Specifically, in this embodiment, the horizontal track 50 can be a straight horizontal track 50, and the horizontal displacement mechanism 60 corresponds to a linear module, and the power output end of the linear module is connected to the base 10, thereby driving the base 10 and its upper structure to move, wherein the structure and driving principle of the horizontal displacement mechanism 60 are basically the same as those of the traditional linear module, and its structure and driving principle are not described in detail here. It can be understood that in other specific embodiments, the horizontal track 50 can also be a curved track or a combined track of a curve and a straight line, and the horizontal displacement drive mechanism 60 can be a mechanism that can drive the base 10 to move along the corresponding track 50.

[0051] In a specific embodiment of the present application, in order to adjust the vertical position and pitch angle of the object carrier 30, the vertical drive mechanism 21 and the pitch drive assembly 40 are provided in various numbers, in various forms, and in various forms of connection with the plurality of object carriers 30, such as:

[0052] In some embodiments, a vertical driving mechanism 21 may be provided on the above-mentioned mounting seat 20, and multiple test object carriers 30 are all installed on the output end of the vertical driving mechanism 21, and multiple test object carriers 30 are driven to move vertically by the same vertical driving mechanism 21. At this time, the test turntable may include a pitch driving component 40, and the pitch driving component 40 has multiple output ends, and each output end is connected to a plurality of test object carriers 30 in a one-to-one correspondence, thereby driving the corresponding test object carrier 30 to adjust the pitch angle; or, the test turntable may also include a plurality of groups of pitch driving components 40 with the same number as the test object carriers 30, and the output ends of the plurality of groups of pitch driving components 40 are connected to a plurality of test object carriers 30 in a one-to-one correspondence, thereby driving each test object carrier 30 to adjust the pitch angle.

[0053] In some other embodiments, the mounting seat 20 may be provided with multiple sets of vertical drive mechanisms 21, and multiple test object carriers 30 are respectively connected to the output ends of the multiple sets of vertical drive mechanisms 21 in a one-to-one correspondence, and each vertical drive mechanism 21 is used to drive the test object carrier 30 connected thereto to move vertically. In this case, the test turntable may include multiple sets of pitch drive components 40, and the multiple sets of pitch drive components 40 are respectively installed at the output ends of the multiple sets of vertical drive mechanisms 21 in a one-to-one correspondence, and the output ends of the multiple sets of pitch drive components 40 are respectively connected to the multiple test object carriers 30 in a one-to-one correspondence, so as to drive each test object carrier 30 to adjust the pitch angle.

[0054] In the related technology, in the cellular communication network, the "vertex excitation" method is often used to achieve network coverage of the service cell. In the "vertex excitation" method, the service cell is approximated as a hexagon, and the base station is set at the three vertices of the hexagon of each cell. Each base station uses three 120° fan-shaped radiation directional antennas to cover one-third of the area of ​​the three adjacent cells respectively. Each cell is covered by three 120° sector antennas, and the area covered by each antenna is a base station sector.

[0055] Based on this, in a specific embodiment of the present invention, Figure 2 and Figure 3 As shown, three groups of vertical driving mechanisms 21 are arranged on the mounting base 20, and the above-mentioned test turntable includes three test object carriers 30 and three groups of pitch driving components 40, wherein the three test object carriers 30 are evenly spaced around the rotation axis of the mounting base 20, and are respectively connected to the output ends of the three groups of vertical driving mechanisms 21, and the three pitch driving components 40 are respectively arranged at the output ends of the three groups of vertical driving mechanisms 21. When in use, the three groups of vertical driving mechanisms 21 respectively drive the three test object carriers 30 to move vertically synchronously.

[0056] In this way, three test object carriers 30 are evenly spaced around the rotation axis of the mounting seat 20, that is, three test object carriers 30 are arranged on the same horizontal plane, and three test base stations are installed on the three test object carriers 30, and in one horizontal plane, the three test object carriers 30 are evenly spaced in the circumferential direction, that is, the angle occupied by the three test object carriers 30 is about 120°, and the angle occupied by the test base station installed on the test object carrier 30 is also about 120°, that is, corresponding to a group of base station sectors, the three base stations occupy 360°, corresponding to a group of complete sectors. In this way, during the test process, it is equivalent to simulating the scene when the base station is actually installed and used in the "vertex excitation" mode, and the three base stations actually used in groups can be tested synchronously, and during the test process, the three tested bases synchronously realize the adjustment and change of position and three-dimensional posture, simulating the change of signal and radiation performance caused by the change of position relationship between the terminal and the base station during actual use, thereby realizing efficient performance testing of the base station to be tested, and the test results are more accurate and reliable.

[0057] It can be understood that in other embodiments, the three groups of vertical driving mechanisms 21 can also respectively drive the three test object carriers 30 to move vertically in sequence, that is, the three test object carriers 30 may not move synchronously according to specific test needs. In this way, the test flexibility is higher and can better meet the needs of various test conditions.

[0058] Furthermore, in this embodiment, if Figure 4 As shown, when three sets of vertical drive mechanisms 21 are provided on the mounting seat 20, the test turntable may also include a multiple of three of the object bearing platforms 30, and a multiple of three of the pitch drive assembly 40. In the direction parallel to the rotation axis of the mounting seat 20, the output end of the same vertical drive mechanism 21 is evenly spaced to connect multiple object bearing platforms 30, and three object bearing platforms 30 at the same setting height form a group of object bearing platforms. For example, Figure 4 As shown, six test object carriers 30 and six groups of pitch drive components 40 are provided, wherein two test object carriers 30 share one vertical drive mechanism 21, and three test object carriers 30 are provided at the same horizontal height, so that two upper and lower groups of test object carriers are provided on the mounting seat 20. In this way, along the vertical direction, multiple test object carriers 30 can be arranged at intervals and connected to the same vertical drive mechanism 21, so as to achieve synchronous detection of more test objects 100 and further improve the detection efficiency. Specifically, in this embodiment, "being at the same setting height" means that the setting heights of the three test object carriers 30 relative to the base 10 (i.e., the setting heights relative to the horizontal plane) are the same.

[0059] It is understandable that in other specific embodiments, more or fewer (such as one or two) test object carriers 30 can be arranged around the rotation axis of the mounting base 20, so as to provide more test base stations for installation and testing, so as to meet the test requirements of base stations of other structural forms. The specific number of the test object carriers 30 is not limited here, and during the design, it can be selected according to the number and form of the base stations in the actual use scenario.

[0060] In this embodiment, if Figure 3 , Figure 5 and Figure 6 As shown, the above-mentioned mounting seat 20 includes a plurality of mounting posts 22 evenly spaced around its rotation axis, each mounting post 22 is arranged perpendicular to the horizontal plane, and the vertical driving mechanism 21 is a linear module installed one-to-one on the mounting posts 22, each linear module includes at least one slider 211, and the slider 211 is connected to the test object carrier 30 and forms the output end of the vertical driving mechanism 21. In this way, the traditional linear module is used as the vertical driving mechanism 21, the technology is mature, and the assembly is simple and convenient. Moreover, along the vertical direction, according to the number of the test object carrier 30, it is only necessary to improve the traditional linear module with a single output end (single slider 211), that is, to provide multiple sliders 211 for multiple test object carriers 30, so as to obtain a vertical driving mechanism 21 with multiple output ends. For example, Figure 4 The same is applicable to the case where multiple groups of test object carrying platforms 30 are provided as shown.

[0061] Specifically, in this embodiment, the structure and driving principle of the vertical driving mechanism 21 are the same as those of a traditional linear module, and the structure and driving principle thereof will not be described in detail herein.

[0062] In this embodiment, if Figure 3 , Figure 5 and Figure 6 As shown, a mounting plate 23 is installed on the side of the slider 211 away from the mounting column 22, and the object carrier platform 30 is pivotally connected to the side of the mounting plate 23 away from the mounting column 22 through a pivot shaft 231. The pitch drive component 40 is installed on the other side of the mounting plate 23 facing the mounting column 22. The output end of the pitch drive component 40 passes through the mounting plate 23 and is connected to the object carrier platform 30. The pitch drive component 40 drives the object carrier platform 30 to perform a pitch movement relative to the mounting plate 23, thereby adjusting the pitch angle of the object carrier platform 30, that is, realizing the adjustment of the pitch angle of the object 100 installed on the object 100 support platform.

[0063] Specifically, in the present embodiment, with the plane parallel to the mounting plate 23 as the reference plane, the pitch drive assembly 40 drives the object carrier 30 to perform a pitch motion in the range of -30° to +30° relative to the reference plane. For example, the pitch drive assembly 40 can drive the object carrier 30 to perform a specific pitch motion at an angle of -30°, -20°, -15°, -10°, -5°, +5°, +10°, +15°, +20° or +30° relative to the reference plane, so as to meet the needs of adjusting the pitch angle during the test of the object 100. Of course, for some other situations, the pitch drive assembly 40 can also drive the object carrier 30 to perform a pitch motion in a larger angle range relative to the reference plane, so as to adjust the pitch posture of the object 100 during the test to a greater extent, which is not limited here.

[0064] In the embodiment of the present invention, Figure 3 , Figure 5 and Figure 6 As shown, the pitch drive assembly 40 may specifically include a drive cylinder 41 and a cylinder support plate 42. The cylinder support plate 42 is vertically mounted on the side of the mounting plate 23 facing the mounting column 22. The drive cylinder 41 is horizontally mounted on the cylinder support plate 42. The drive shaft of the drive cylinder 41 is pivotally connected to the object-to-be-tested platform 30 and forms the output end of the pitch drive assembly 40. Specifically, the drive shaft of the drive cylinder 41 is connected to the lower end portion of the object-to-be-tested platform 30 facing the base 10. In this way, the cylinder is used as the driving core of the pitch drive assembly 40. The cylinder pushes or pulls the object-to-be-tested platform 30 to rotate around the pivot axis 231 through the output shaft, so that the pitch angle of the object-to-be-tested platform 30 can be adjusted. The pitch drive assembly 40 has a simple structure, and the pitch angle adjustment of the object-to-be-tested platform 30 is fast and convenient. It can be understood that in other embodiments, the pitch drive assembly 40 can also use other electric components or structures such as motors as the driving core to drive the pitch movement of the object carrier 30 connected thereto. The description of the pitch drive assembly 40 here is only exemplary and should not be understood as the only limitation.

[0065] In another embodiment of the present invention, Figure 5 and Figure 6 As shown, the above-mentioned object carrier 30 includes a mounting back plate 31 and a supporting bottom plate 32. The supporting bottom plate 32 is vertically connected to one end of the mounting back plate 31 facing the base 10.
