Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to fig. 1 to 7 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be 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 be indirectly connected to the other element.
It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.
Reference in the specification to "one embodiment," "some embodiments," or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the invention. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In the related art, for a conventional 2G, 3G or 4G base station, since an antenna and an RRU (Radio Remote unit) are separated from each other and connected by a Radio frequency cable, the antenna and the RRU are relatively independent and do not affect each other, and their respective performances can be tested by independent tests. For example, the radiation performance test of the antenna can be completed in a microwave darkroom in a far-field or near-field manner, and the radio frequency index of the RRU can be measured in a laboratory in a conduction manner. Therefore, when the test system of the traditional base station is used for testing the 5G base station, the active antenna system needs to be split into a passive antenna array and an RRU to respectively perform an antenna radiation performance test and a radio frequency conduction test.
However, for a 5G base station, because the antenna and the RRU are integrated together, the interference factors such as electromagnetic coupling and active standing wave cannot be completely eliminated, and because the calibration and amplitude-phase weighting of the active antenna are completed by a series of active devices on each radio frequency channel, the method of amplitude-phase weighting through a passive power division network is very different from that of a passive antenna array. Therefore, for a 5G base station adopting a large-scale MIMO (Multiple Input Multiple Output) active antenna technology, an integrated OTA test mode can effectively reflect performance indexes thereof, and particularly for a millimeter wave frequency band, since the frequency band is higher, the size of equipment is smaller, the problem of electromagnetic interference is more prominent, the difficulty of splitting the millimeter wave frequency band for testing is further increased, and the testing effectiveness and the testing efficiency are difficult to guarantee.
Based on this, the present invention provides a test turret, as shown in fig. 2 to 7, which is suitable for, but not limited to, performance testing of a base station, and is particularly suitable for performing an integrated OTA test of a 5G base station. The test turret of the present application is specifically described below with reference to specific examples.

Wherein, base 10 is equipped with horizontal rotation mechanism 11, and mount pad 20 is installed on base 10 to with the output of horizontal rotation mechanism 11 continuous, horizontal rotation mechanism 11 is used for driving mount pad 20 relative base 10 horizontal rotation. In this embodiment, the testing turntable further includes a plurality of object bearing tables 30 to be tested, the object bearing tables 30 to be tested are used for installing the object 100 to be tested for performance testing, the installation base 20 is provided with the vertical driving mechanism 21, the object bearing tables 30 to be tested are movably installed on the installation base 20 and are arranged around the rotation axis of the installation base 20, the output end of the vertical driving mechanism 21 is connected with the object bearing tables 30 to be tested, so as to drive the object bearing tables 30 to be tested to vertically move relative to the installation base 20, and therefore the setting height of each object bearing table 30 to be tested along the vertical direction is adjusted and changed. The object 100 to be tested can be a base station to be tested, but is not limited to the base station to be tested, and all objects capable of being tested by using the testing turntable in this embodiment should be covered in the protection scope of this application.
In addition, the test turntable further comprises a pitching driving assembly 40, the pitching driving assembly 40 is installed at the output end of the vertical driving mechanism 21, and the output end of the pitching driving assembly 40 is connected with the plurality of object bearing tables 30 to drive the object bearing tables 30 to perform pitching motion, so as to adjust the pitching angle of each object bearing table 30.
When the test turntable provided by the embodiment of the invention is used, a plurality of objects to be tested 100 such as base stations to be tested are correspondingly arranged on a plurality of object bearing tables 30 to be tested. The vertical driving mechanism 21 drives the object bearing table 30 to reciprocate along the vertical direction, and the vertical height position of the object 100 to be measured is adjusted and changed; the horizontal rotation mechanism 11 drives the mounting base 20 to rotate, so as to adjust and change the horizontal position of the object 100 to be tested mounted on the object bearing table 30, i.e. change the azimuth angle of the object 100 to be tested; the pitch driving assembly 40 drives and adjusts the pitch angle of each object bearing platform 30. Thus, the horizontal rotation mechanism 11, the vertical driving mechanism 21 and the pitching driving assembly 40 are mutually matched, so that the three-dimensional posture adjustment of the object 100 to be tested installed on the object bearing table 30 can be realized, and the three-dimensional posture of the object 100 to be tested is correspondingly adjusted according to the test requirement in the test process, thereby completing the performance test of the object 100 to be tested.
More importantly, as shown in fig. 2 and 3, the test turntable of the present embodiment is provided with a plurality of object bearing tables 30 around the rotation axis of the mounting base 20, and when the object 100 is a base station to be tested, the plurality of base stations to be tested used simultaneously are mounted on the object bearing tables 30 in a one-to-one correspondence manner according to actual use conditions for testing. Therefore, a plurality of base stations to be tested can correspondingly form a group of complete sectors during testing, which is equivalent to simulating the actual installation scene of the base stations in service areas such as cells, and the plurality of base stations to be tested can realize synchronous position movement and adjustment and change of three-dimensional postures during testing, namely simulating the change of connection performance related to beam scanning and sector switching during wireless signal transmission between a terminal and the base stations during actual use, thereby meeting the requirements of integrated testing (such as integrated OTA testing and the like) of 5G base stations, obtaining test data capable of more effectively reflecting performance indexes of the base stations to be tested, and having more reference value on test results.

Specifically, in the present embodiment, the horizontal rail 50 may be a linear horizontal rail 50, the horizontal displacement mechanism 60 is a linear module, and a power output end of the linear module is connected to the base 10, so as to drive the base 10 and the upper structure thereof to move, wherein the structure and the driving principle of the horizontal displacement mechanism 60 are substantially the same as those of the conventional linear module, and the structure and the driving principle thereof are not described herein again. It is understood that in other embodiments, the horizontal rail 50 may be a curved rail or a combination of curved and straight rails, and the horizontal displacement driving mechanism 60 may be selected to drive the base 10 to move along the corresponding rail 50.
In the embodiment of the present application, in order to adjust the vertical position and the pitch angle of the object bearing table 30, there are various setting numbers and setting forms of the vertical driving mechanism 21 and the pitch driving assembly 40, and connection forms between the vertical driving mechanism and the pitch driving assembly and the object bearing tables 30, such as:

At this time, the testing turntable may include a pitching driving assembly 40, where the pitching driving assembly 40 has a plurality of output ends, and each output end is respectively connected with the plurality of object bearing tables 30 in a one-to-one correspondence manner, so as to drive the corresponding object bearing tables 30 to adjust the pitching angle; or, the test turntable may also include a plurality of groups of pitching driving assemblies 40 with the same number as the object bearing tables 30, and the output ends of the plurality of groups of pitching driving assemblies 40 are respectively connected with the plurality of object bearing tables 30 in a one-to-one correspondence manner, so as to drive each object bearing table 30 to adjust the pitching angle.
In other embodiments, a plurality of sets of vertical driving mechanisms 21 may be further disposed on the mounting base 20, the plurality of object bearing tables 30 are respectively connected to output ends of the plurality of sets of vertical driving mechanisms 21 in a one-to-one correspondence manner, and each vertical driving mechanism 21 is respectively used for driving the object bearing table 30 connected thereto to move vertically. At this time, the testing turntable may include a plurality of groups of pitching driving assemblies 40, the plurality of groups of pitching driving assemblies 40 are installed at the output ends of the plurality of groups of vertical driving mechanisms 21 in a one-to-one correspondence, and the output ends of the plurality of groups of pitching driving assemblies 40 are connected with the plurality of object bearing tables 30 in a one-to-one correspondence, so as to drive each object bearing table 30 to adjust the pitching angle.
In the related art, in a cellular communication network, network coverage of a serving cell is often implemented by using a "vertex excitation" mode, in the "vertex excitation" mode, the serving cell is approximated to be a hexagon, base stations are arranged on three vertices of the hexagon of each cell, each base station uses three pairs of 120 ° sector-radiated directional antennas to respectively cover one-third areas of three adjacent cells, each cell is covered by three pairs of 120 ° sector-antennas together, and an area covered by each pair of antennas is a sector of the base station.
Based on this, in an embodiment of the present invention, as shown in fig. 2 and fig. 3, three sets of vertical driving mechanisms 21 are disposed on the mounting base 20, and the test turntable includes three object-to-be-tested loading platforms 30 and three sets of pitching driving assemblies 40, wherein the three object-to-be-tested loading platforms 30 are disposed around the rotation axis of the mounting base 20 at regular intervals and are respectively connected to the output ends of the three sets of vertical driving mechanisms 21, and the three pitching driving assemblies 40 are respectively disposed at the output ends of the three sets of vertical driving mechanisms 21, so that when in use, the three sets of vertical driving mechanisms 21 respectively drive the three object-to-be-tested loading platforms 30 to synchronously move vertically.
Thus, the three object bearing tables 30 are uniformly spaced around the rotation axis of the mounting base 20, that is, three object bearing tables 30 are arranged on the same horizontal plane, the three object bearing tables 30 are correspondingly provided with three base stations to be tested, and in a horizontal plane, the three object bearing tables 30 are uniformly circumferentially spaced, that is, the angle occupied by the three object bearing tables 30 is about 120 °, the angle occupied by the base stations to be tested mounted on the object bearing tables 30 is also about 120 °, that is, the three base stations occupy 360 ° and correspond to a complete set of sectors. Therefore, in the test process, the method is equivalent to simulating the scene of the base station in the 'vertex excitation' mode during actual installation and use, three base stations which are actually used in a group can be synchronously tested, in the test process, the three tested bases synchronously realize the adjustment and change of the position and the three-dimensional posture, and the change of the signal and the radiation performance caused by the change of the position relation between the terminal and the base station in the actual use process is simulated, so that the high-efficiency performance test of the base station to be tested is realized, and the test result is more accurate and reliable.
It can be understood that, in other embodiments, the three groups of vertical driving mechanisms 21 may also respectively drive the three object bearing tables 30 to sequentially move vertically, that is, the three object bearing tables 30 may not move synchronously according to specific test requirements, so that the test flexibility is higher, and the requirements of various test conditions can be satisfied more.
Further, in this embodiment, as shown in fig. 4, when three sets of vertical driving mechanisms 21 are disposed on the mounting base 20, the testing turntable may also include multiple numbers of the object bearing tables 30, and multiple numbers of the pitching driving assemblies 40.

For example, as shown in fig. 4, six object bearing tables 30 and six groups of pitching driving assemblies 40 are provided, wherein two object bearing tables 30 share one vertical driving mechanism 21, and three object bearing tables 30 are disposed at the same horizontal height, so that two upper and lower groups of object bearing table groups are disposed on the mounting base 20. In this way, in the vertical direction, a plurality of object bearing tables 30 connected to the same vertical driving mechanism 21 may be disposed at intervals, so as to realize synchronous detection of more objects 100 to be detected, and further improve the detection efficiency. Specifically, in the present embodiment, the phrase "located at the same installation height" means that the installation heights of the three object bearing tables 30 (i.e. the installation heights of the three object bearing tables relative to the horizontal plane) are the same.
It will be appreciated that in other embodiments, more or fewer (e.g., one or two) subject carriers 30 may be provided about the axis of rotation of the mounting base 20 for more base stations under test to meet the testing requirements of base stations of other configurations. The specific number of the set object bearing tables 30 is not limited uniquely, and the number and the set form of the set object bearing tables can be selected according to the actual use scene of the base station.
In this embodiment, as shown in fig. 3, 5 and 6, the mounting base 20 includes a plurality of mounting posts 22 evenly spaced around a rotation axis of the mounting base, each mounting post 22 is disposed perpendicular to a horizontal plane, the vertical driving mechanisms 21 are linear modules mounted on the mounting posts 22 in a one-to-one correspondence, each linear module includes at least one sliding block 211, and the sliding block 211 is connected to the object-to-be-tested carrier table 30 and forms an output end of the vertical driving mechanism 21. Therefore, the traditional linear module is used as the vertical driving mechanism 21, the technology is mature, and the assembly is simple and convenient. In addition, along the vertical direction, according to the number of the object bearing tables 30 to be tested, the vertical driving mechanism 21 with a plurality of output ends can be manufactured by only improving the traditional linear module with a single output end (a single slide block 211), namely, the plurality of slide blocks 211 are arranged for the plurality of object bearing tables 30 to be tested, and the vertical driving mechanism is also applicable to the situation that a plurality of groups of object bearing tables 30 to be tested are arranged as shown in fig. 4.
