Detailed Description

Embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that the drawings are not necessarily to scale. The described embodiments are exemplary and are not intended to limit the disclosure, these features may be combined with or substituted for the features of the embodiments in the same or similar manner. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

In the present disclosure, a test object is a wireless device, and the wireless device refers to a device capable of performing wireless communication, for example, may be a small device such as a computer, a mobile phone, a tablet, a wearable intelligent device, a wireless router, or a large device such as a base station, a large antenna, a vehicle, or an airplane. The performance of a wireless device refers to the wireless signal transmission capabilities of the antenna of the wireless device, including transmission performance or/and reception performance. It will be appreciated that for large devices, a device may have multiple communication modules, each of which may be tested separately to obtain corresponding wireless performance, as required by the test.

An embodiment of an aspect of the present disclosure is a wireless performance testing apparatus, including: testing the antenna; the scanning mechanism is used for controlling the test antenna to reach a plurality of preset test points; and at least one universal joint arranged on the scanning mechanism, wherein the universal joint is suitable for installing the test antenna, and the universal joint is used for controlling the test antenna to point to a target position or/and controlling the test antenna to rotate to reach a preset polarization direction for each test point.

Optionally, the scanning mechanism is any one of:

the universal joint can move along the guide rail;

a rotating arm adapted to drive the universal joint to rotate around a preset rotating axis;

and the universal joint is arranged at the tail end of the mechanical arm.

Optionally, the testing device further comprises a moving component for controlling the movement of the scanning mechanism, and as an example, the moving component may be a movable platform carrying the scanning mechanism, for moving the scanning mechanism to a desired position during testing, or/and controlling the scanning mechanism to rotate around the tested piece during testing.

As shown in fig. 1, according to one embodiment of the test apparatus, the test apparatus includes an arc-shaped guide rail 100, 2 universal joints 200 are mounted on the arc-shaped guide rail 100, and a test antenna 300 is mounted on the universal joints 200. The arc track 100 performs arc movement along the track by controlling the universal joint 200, so that the test antenna 300 performs corresponding arc movement and reaches a plurality of preset test points, and the arc movement track of the test antenna 300 is the scanning track of the spherical scanning test. When the test antenna 300 reaches each test point, the gimbal 200 controls the test antenna 300 to point to a target position, or/and controls the test antenna 300 to rotate to reach a preset polarization direction. It should be noted that, the test device of this embodiment has 2 test antennas, and may sample at two preset test points at the same time, for example, the positions of the 2 test antennas may be set to an angle that satisfies the interval between adjacent sampling points. In this embodiment, the arc guide rail is one-half arc, the test antenna moves on the arc guide rail once, and can sample multiple test points on the one-half arc, and the test antenna can obtain the scan test value of the upper half sphere of the tested piece by combining the rotation of the turntable bearing the tested piece at a certain angle interval or the movement of the arc guide rail itself and repeating the sampling for multiple times. The shape of the arc-shaped guide rail is not limited to the half arc of the example shown in the present embodiment, but may be, for example, a quarter arc.

The foregoing "target position" and "preset polarization direction" are explained herein.

The test antenna described in this disclosure is directed to the target location, which is understood to be directed in a fixed radiation direction (typically the maximum gain direction or near the maximum gain direction). In some related art, the maximum radiation direction of the antenna coincides with the normal direction of the antenna port. The target position refers to the phase center of the antenna of the measured object, i.e. the equivalent radiation center of the antenna. It will be appreciated that there may be multiple antennas to be tested for a single part under test, and thus multiple corresponding phase centers. In the related art, the OTA (Over The Air) test requires that a phase center is disposed at the center of a test system (i.e., the center of a test area or the center of a test rotating shaft), and a three-dimensional wireless performance test is performed on a tested piece with the center, and during the test, a test antenna is aligned with the center in a fixed radiation direction to obtain larger transmission energy. When the phase center of the tested piece is not arranged in the center of the test system due to the large volume, the large weight, the inconvenience of moving and the like, the test antenna points to the phase center in different radiation directions at different test points, and the test antenna has different gains in different radiation directions, so that the test error is caused. Especially when the phase center is far from the center of the test system, or in the case of a narrower test antenna beam width, the test antenna may point to the phase center with side lobes or even nulls at some test points, further increasing the uncertainty of the test. In the related art, the geometric center of the antenna is generally determined as the phase center thereof, that is, the target position. For some antennas, however, the actual phase center differs significantly from the geometric center position, in which case the apparent phase center may be determined as the target position. The apparent phase center is a reference point at which the main lobe of the antenna remains relatively constant in phase of its radiated field over a range. The testing device can solve the problems, when the target position of the tested piece is not placed in the center of the testing system, the universal joint is used for controlling the testing antenna to point to the target position, the radiation energy of the tested piece is accurately obtained, and the testing result can accurately reflect the antenna performance of the tested piece.

In the related art, the test specification of the OTA requires that the polarization directions of the test points are kept consistent in a single test to ensure the test accuracy. The testing device adjusts the polarization direction of the testing antenna through the universal joint so as to ensure that the polarization directions of the testing antenna at all the testing points are consistent.

As shown in fig. 2, according to one embodiment of the testing apparatus, the testing apparatus includes a rotating arm 100, 1 gimbal 200 is mounted on the rotating arm 100, and a testing antenna 300 is mounted on the gimbal 200. The rotating arm 100 is suitable for driving the universal joint 200 to rotate around a preset rotation axis L through the rotating joint 101, so that the test antenna 300 performs corresponding arc-shaped movement and reaches a plurality of preset test points, and the arc-shaped movement track of the test antenna 300 is the scanning track of the spherical scan test. When the test antenna 300 reaches each test point, the gimbal 200 controls the test antenna 300 to point to a target position, or/and controls the test antenna 300 to rotate to reach a preset polarization direction.

As shown in fig. 3, according to one embodiment of the test apparatus, the test apparatus includes a robot arm 100, and 1 universal joint 200 is mounted at the end of the robot arm 100, and a test antenna 300 is mounted on the universal joint 200. The mechanical arm 100 drives the universal joint 200 to move, so that the test antenna 300 reaches a plurality of preset test points according to a preset scanning track. When the test antenna 300 reaches each test point, the gimbal 200 controls the test antenna 300 to point to a target position, or/and controls the test antenna 300 to rotate to reach a preset polarization direction.

Compared with the guide rail and the rotating arm, the mechanical arm can provide a more flexible scanning mode. However, the mechanical arm has application limitation. In the related art, the working space is the reach of the end of the mechanical arm, and includes two types: a reachable working space, i.e. a spatial area where the end of the mechanical arm can reach from at least one direction; smart working space, i.e. the area of space where the end of a robot arm can reach from any direction. The robotic arm may control the test antenna to multiple test points within its workspace, but for a robotic arm with less degrees of freedom, its smart workspace may be less wide and the pointing angle and polarization direction of the test antenna may not be adjustable at some test points. The universal joint is additionally arranged at the tail end of the mechanical arm, so that the range of the smart working space of the mechanical arm can be expanded. For the mechanical arm with more degrees of freedom, the range of the smart working space is relatively larger, but for complex scanning tracks or larger measured pieces, application limitation still exists possibly due to joint limitation and other reasons, and the redundant degree of freedom of the mechanical arm can be increased by adding the universal joint.

An embodiment of one aspect of the present disclosure is a wireless performance testing system, including a turntable for controlling rotation of a tested piece, and the foregoing testing device.

Optionally, according to an embodiment of the test system, an anechoic chamber is further included. The anechoic chamber provides a test environment for a test, and specifically, the anechoic chamber can be a full-wave anechoic chamber, an EMC anechoic chamber, a field provided with a wave absorbing screen, or the like.

Optionally, according to an embodiment of the test system, a test meter is further included. The test meter is used to generate test signals for transmission to the test antenna, and/or to receive signals from the wireless device to obtain test data.

As shown in fig. 4, according to one embodiment of the test system, the test system includes: test antenna 300, arcuate guide 100, gimbal 200, turret 400, anechoic chamber 500, and a test meter (not shown) connected to test antenna 300.

An embodiment of the present disclosure is a method for testing wireless performance, as shown in fig. 5, according to one embodiment of the testing method, including the steps of:

step S11, controlling the test antenna to reach a plurality of preset test points;

step S12, for each test point, controlling the test antenna to point to the target position and reach the preset polarization direction;

and S13, obtaining test values of all the test points, and obtaining a test result according to the test values.

Optionally, according to an embodiment of the testing method, the predetermined test point is located on a virtual sphere.

Optionally, according to an embodiment of the testing method, the target position is a phase center of the tested piece.

Alternatively, according to one embodiment of the test method, as shown in fig. 6, the test method is a spherical scan test, comprising the steps of:

step S21, controlling the test antenna to reach a plurality of preset test points in a fixed arc-shaped motion track;

step S22, for each test point, controlling the test antenna to point to a target position and reach a preset polarization direction, and obtaining a test value of the test point;

step S23, the tested piece rotates a preset angle to obtain an updated target position, and the steps are repeated until test values of all test points are obtained, and a test result is obtained according to the test values.

An exemplary description of the test method of the present disclosure is provided below in connection with a test system as shown in fig. 4.

Referring to fig. 4, a test coordinate system is established with the center of the test system as the origin of coordinates, with a plane parallel to the plane of the turntable 400 as an XY plane, and with an axis perpendicular to the XY plane and facing upward on the ground as a Z-axis forward direction. The arc-shaped rail 100 is fixedly provided. The center of rotation of the turret 400 is located at the origin of the test system. The object 600 is a vehicle, the object 600 has 4 antennas to be tested, the phase centers thereof, i.e. the target positions are a, B, C, D, respectively, and the positions of the target positions in the test coordinate system are known. The target position A is located at the origin of the test coordinate system, and the other three target positions deviate from the origin of the test coordinate system.

The test procedure for the target position a is:

step S201, the arc-shaped guide rail 100 controls the test antenna 300 to move along a fixed half arc along the track, wherein the arc takes the origin of the test coordinate system as the center of a circle, and the arc-shaped movement track of the arc-shaped guide rail comprises a plurality of test points 301 with preset sampling interval angles (for example, 15 °);

step S202, at each test point 301, controlling the test antenna 300 to point to the target position a and reach the preset polarization direction through the universal joint 200, and obtaining a test value of each test point 301; it should be noted that, because the target position a is located at the origin of the test system, when the test antenna 300 is adjusted in the pointing direction and the polarization direction at any test point 301, no adjustment is needed at other test points 301;

step S203, the turntable 400 rotates a preset angle on the XY plane of the test coordinate system, the step S201 and the step S202 are repeated to obtain a test value of each test point 301 of the turntable 400 at the rotation angle, the turntable rotates a preset angle again, the step S201 and the step S202 are repeated until test values of all test points of the turntable 400 at all rotation angles are obtained, and a test result is obtained according to the test values. It should be noted that, in the present embodiment, the target position a is located at the origin of the test system, so after the turntable 400 rotates, the coordinates of the target position a in the test coordinate system are not changed. In this embodiment, the preset test point is located on a virtual hemispherical surface, that is, a scan test of the upper hemispherical surface is performed on the tested piece, so as to obtain the wireless performance in the corresponding direction. In the present disclosure, optionally, the test may be performed in a near field range of the tested piece, and the far field performance of the antenna is obtained as a test result by calculating the test value through near field-far field conversion.

Referring to fig. 7, the test procedure for the target position B is:

step S211, the arc-shaped guide rail 100 controls the test antenna 300 to move along a fixed half arc along the track, wherein the arc takes the origin of the test coordinate system as the center of a circle, and the arc-shaped movement track comprises a plurality of test points 301 with preset sampling interval angles (for example, 15 °);

step S212, at each test point 301, controlling the test antenna 300 to point to the target position B and reach the preset polarization direction through the universal joint 200, and obtaining a test value of each test point 301;

step S213, rotating the turntable 400 on the XY plane of the test coordinate system by a preset angle to obtain an updated target position B, repeating step S211 and step S212 to obtain a test value of each test point 301 of the turntable 400 at the rotation angle, rotating the turntable by a preset angle to obtain an updated target position B, repeating step S211 and step S212 until test values of all test points of the turntable 400 at all rotation angles are obtained, and obtaining a test result according to the test values. It should be noted that, in the present embodiment, since the target position B deviates from the origin of the test coordinate system and the arc-shaped guide rail 100 is fixedly disposed, when the turntable 400 rotates, the coordinates of the target position B in the test coordinate system are changed, and before repeating the steps S211 and S212, the coordinates of the target position B need to be updated.

The test steps for the target positions C and D are similar and will not be described in detail herein.

It should be noted that, for the test of the phase center deviated from the center of the test system, for example, the distances between each test point and the target position may be different, and in the step of obtaining the test result according to the test values, as an example, the test result is obtained after performing compensation calculation of the gain and the path loss of the test antenna according to the polarization direction of the test antenna and the distance between the test antenna and the target position for each test value.
