Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the present invention is further described in detail below with reference to fig. 1 to 7 and the embodiment. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

It will be understood that when an element is referred to as being "mounted" 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 is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are merely for convenience in describing and simplifying the description based on the orientation or positional relationship shown in the drawings, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are 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," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In the related technology, for the traditional 2G, 3G or 4G base station, because the antenna and the RRU (Radio Remote Unite, remote radio unit) are mutually separated and are connected through a radio frequency cable, the antenna and the RRU are relatively independent, the performances of the antenna and the RRU are not affected, and the performances of the antenna and the RRU can be respectively checked through independent tests. For example, the radiation performance test of the antenna can be completed in a far field or near field mode in a microwave darkroom, and the radio frequency index of the RRU can be measured in a conduction mode in a laboratory. Therefore, when the testing system of the traditional base station is used for testing the 5G base station, the active antenna system is required to be split into a passive antenna array and an RRU to respectively perform antenna radiation performance test and radio frequency conduction test.

However, for the 5G base station, because the antenna is integrated with the RRU, interference factors such as electromagnetic coupling and active standing waves of the antenna cannot be completely eliminated, and because calibration and amplitude phase weighting of the active antenna are completed through a series of active devices on each radio frequency channel, the mode of amplitude phase weighting of the active antenna and the passive antenna array through a passive power division network is greatly different. Therefore, for a 5G base station adopting a large-scale MIMO (Multiple Input Multiple Output, multiple-input multiple-output) active antenna technology, the integrated OTA test mode can effectively reflect the performance index, especially for the millimeter wave frequency band, the electromagnetic interference problem is more prominent because the frequency band is higher and the equipment size is smaller, the difficulty of splitting the antenna for testing is further increased, and the test effectiveness and the test efficiency are difficult to ensure.

Based on this, the present application provides a test turntable, as shown in fig. 2 to 7, which is applicable, but not limited to, performance test for a base station, and is particularly applicable to integrated OTA test for a 5G base station. The test turret of the present application will be specifically described with reference to specific examples.

Wherein, the base 10 is provided with a horizontal rotation mechanism 11, the mounting seat 20 is mounted on the base 10 and is connected with an output end of the horizontal rotation mechanism 11, and the horizontal rotation mechanism 11 is used for driving the mounting seat 20 to horizontally rotate relative to the base 10. In this embodiment, the testing turntable further includes a plurality of test object carrying tables 30, the test object carrying tables 30 are used for mounting test objects 100 to be tested, the mounting base 20 is provided with a vertical driving mechanism 21, the plurality of test object carrying tables 30 are movably mounted on the mounting base 20 and are distributed around the rotation axis of the mounting base 20, and the output end of the vertical driving mechanism 21 is connected with the plurality of test object carrying tables 30 to drive the test object carrying tables 30 to move vertically relative to the mounting base 20, so as to adjust and change the setting height of each test object carrying table 30 along the vertical direction. The object to be tested 100 may be a base station to be tested, but is not limited to the base station to be tested, and any object that can be tested by using the testing turntable in the embodiment should be covered in the protection scope of the present application.

In addition, the test turntable further comprises a pitching driving assembly 40, the pitching driving assembly 40 is mounted 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 do pitching motion, so that the pitching angle of each object bearing table 30 is adjusted.

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 installed 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 to adjust and change the vertical height position of the object 100, the horizontal rotating mechanism 11 drives the mounting seat 20 to rotate, so that the horizontal position of the object 100 mounted on the object bearing table 30 is adjusted and changed, namely the azimuth angle of the object 100 is changed, and the pitching driving assembly 40 drives and adjusts the pitching angle of each object bearing table 30. In this way, 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 of the object 100 to be tested mounted on the object bearing table 30 can be adjusted, and in the testing process, the three-dimensional posture of the object 100 to be tested is correspondingly adjusted according to the testing requirement, thereby completing the performance test of the object 100 to be tested.

More importantly, as shown in fig. 2 and 3, the testing turntable of the present embodiment is provided with a plurality of bearing tables 30 of the to-be-tested objects around the rotation axis of the mounting base 20, when the to-be-tested object 100 is a base station to be tested, according to the actual use situation, the plurality of base stations to be tested used simultaneously are correspondingly installed on each bearing table 30 of the to-be-tested object one by one 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 the service areas such as the cells, and the plurality of base stations to be tested can realize synchronous position movement and three-dimensional posture adjustment and change during testing, namely simulate the change of the connection performance related to beam scanning and sector switching during wireless signal transmission between the terminal and the base stations during actual use, thereby meeting the requirements of the integrated testing (such as the integrated OTA testing and the like) of the 5G base stations, obtaining the testing data capable of more effectively reflecting the performance indexes of the base stations to be tested, and having more reference value in the testing result.

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 correspondingly, and the power output end of the linear module is connected with the base 10, so as to drive the base 10 and the upper structure thereof to move, wherein the structure and driving principle of the horizontal displacement mechanism 60 are substantially the same as those of the conventional linear module, and the structure and driving principle thereof are not repeated here. It will be appreciated 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 a mechanism capable of driving the base 10 to move along the corresponding rail 50.

In the embodiment of the present application, in order to implement the vertical position adjustment and the pitch angle adjustment of the object bearing table 30, the number and the arrangement form of the vertical driving mechanism 21 and the pitch driving assembly 40 and the connection form of the vertical driving mechanism and the pitch driving assembly with a plurality of object bearing tables 30 are various, for example:

In some embodiments, a vertical driving mechanism 21 may be disposed on the mounting base 20, and a plurality of object bearing tables 30 are mounted on the output end of the vertical driving mechanism 21, and the plurality of object bearing tables 30 are driven to move vertically by the same vertical driving mechanism 21. At this time, the test turntable may include a plurality of pitch driving assemblies 40, where each of the plurality of pitch driving assemblies 40 has a plurality of output ends, and each of the plurality of output ends is connected to the plurality of test object holders 30 in a one-to-one correspondence manner, so as to drive the corresponding test object holders 30 to adjust the pitch angle, or the test turntable may include a plurality of sets of pitch driving assemblies 40, which are the same as the number of the test object holders 30, and each of the plurality of output ends of the plurality of sets of pitch driving assemblies 40 is connected to the plurality of test object holders 30 in a one-to-one correspondence manner, so as to drive each of the test object holders 30 to adjust the pitch angle.

In other embodiments, the mounting base 20 may further be provided with a plurality of sets of vertical driving mechanisms 21, where the plurality of to-be-measured object carrying platforms 30 are respectively connected to the 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 to-be-measured object carrying platform 30 connected thereto to move vertically. At this time, the test turntable may include a plurality of groups of pitch driving assemblies 40, where the plurality of groups of pitch 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 manner, and the output ends of the plurality of groups of pitch driving assemblies 40 are 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 be tested to adjust the pitch angle.

In the related art, in a cellular communication network, network coverage of a serving cell is often implemented in a "vertex excitation" manner, in the "vertex excitation" manner, the serving cell is approximated to a hexagon, a base station is arranged on three vertices of each cell hexagon, each base station adopts three pairs of directional antennas radiating in a sector of 120 ° to cover respective third areas of three adjacent cells, each cell is jointly covered by three pairs of sector antennas of 120 °, and the area covered by each pair of antennas is a base station sector.

Based on this, in an embodiment of the present invention, as shown in fig. 2 and 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 carrying platforms 30 and three sets of pitch driving assemblies 40, where the three object-to-be-tested carrying platforms 30 are disposed at uniform intervals around the rotation axis of the mounting base 20 and are respectively connected to the output ends of the three sets of vertical driving mechanisms 21, and the three pitch driving assemblies 40 are respectively disposed at the output ends of the three sets of vertical driving mechanisms 21, and in use, the three sets of vertical driving mechanisms 21 respectively drive the three object-to-be-tested carrying platforms 30 to move vertically synchronously.

In this way, the three bearing tables 30 for the to-be-detected object are uniformly arranged at intervals around the rotation axis of the mounting seat 20, namely, three bearing tables 30 for the to-be-detected object are arranged on the same horizontal plane, the three bearing tables 30 for the to-be-detected object are correspondingly arranged at three base stations for the to-be-detected object, and in the same horizontal plane, the bearing tables 30 for the to-be-detected object are circumferentially uniformly arranged at intervals, namely, the angles occupied by the bearing tables 30 for the to-be-detected object are about 120 degrees, the angles occupied by the base stations for the to-be-detected object arranged on the bearing tables 30 for the to-be-detected object are about 120 degrees, namely, a group of base station sectors are correspondingly arranged, and the three base stations occupy 360 degrees and correspond to a group of complete sectors. In this way, in the test process, the scene is equivalent to the scene when the base station is actually installed and used in the 'vertex excitation' mode, the three base stations which are actually used in groups can be synchronously tested, in the test process, the three tested base stations synchronously realize the adjustment and change of the position and the three-dimensional gesture, and the change of the signal and the radiation performance caused by the change of the position relation between the terminal and the base stations 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 appreciated that, in other embodiments, the three sets of vertical driving mechanisms 21 may also respectively drive the three object bearing tables 30 to vertically move sequentially, that is, the three object bearing tables 30 may not synchronously move according to specific testing requirements, so that the testing flexibility is higher, and the requirements of various testing conditions can be met.

Further, in the present embodiment, as shown in fig. 4, when three sets of vertical driving mechanisms 21 are provided on the mounting base 20, the test turntable may also include three times the number of test object carrying tables 30, and three times the number of pitch driving assemblies 40.

For example, as shown in fig. 4, six load-bearing tables 30 for objects to be detected and six sets of pitch driving assemblies 40 are provided, wherein two load-bearing tables 30 for objects to be detected share one vertical driving mechanism 21, and three load-bearing tables 30 for objects to be detected are disposed on the same horizontal height, so that an upper load-bearing table set and a lower load-bearing table set for objects to be detected are disposed on the mounting base 20. In this way, along the vertical direction, a plurality of to-be-detected object bearing tables 30 can be arranged at intervals to be connected with the same vertical driving mechanism 21, so that synchronous detection of more to-be-detected objects 100 is realized, and the detection efficiency is further improved. Specifically, in the present embodiment, "at the same setting height" means that the setting heights of the three object-to-be-measured carrying tables 30 (i.e., the setting heights with respect to the horizontal plane) are the same.

It will be appreciated that in other embodiments, more or fewer (e.g., one or two) test object carriers 30 may be provided about the axis of rotation of the mounting base 20 for more base stations to be tested to meet the testing requirements of other base stations. The specific number of the carriers 30 to be tested is not limited only, and can be selected according to the number and the form of the base stations in actual use.
