Description

Technical Field

[0001] The invention relates to the technical field of electronic component detection, in particular to an antenna anti-interference simulation detection device. Background Art

[0002] Antenna is a kind of converter, which converts the guided wave propagating on the transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all of which use electromagnetic waves to transmit information, rely on antennas to work.

[0003] In the prior art, when the antenna is close to a metal material, an eddy current will be formed on the metal material, so that the energy of the antenna is consumed on the metal material, making the data transmission effect of the antenna worse. In order to solve this problem, the prior art usually attaches a layer of absorbing material to the back of the antenna to reduce the interference of the metal material to the antenna, thereby improving the anti-interference performance of the antenna.

[0004] The existing technology generally detects the anti-interference performance of the antenna by fixing the interference structure in the radiation direction of the directional antenna through a fixed structure, and detects the degree of influence caused by the directional antenna receiving or sending signals in the radiation direction; however, the existing detection equipment has certain defects. The radiation intensity of the antenna in each direction is not completely consistent. At the same time, the actual installation environment of the antenna is also uncertain. The existing detection equipment cannot effectively and comprehensively simulate the actual anti-interference degree of the antenna, so there is often a "generalized" test result for the anti-interference performance of the antenna.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] In one embodiment;

[0033] See also Figure 1 , provides an antenna anti-interference simulation detection device, including a detection machine 1, on which the detection machine 1 is provided:

[0035] The detection rack 13 is provided with a plurality of lanes and is set up on the detection platform 1. The detection rack 13 is arranged at a certain angle along the edge area of ​​the detection platform 1 with the loading kit 12 as the center; the detection rack 13 is provided with an interferometer 14 and an adjustment component 15 for adjusting the interferometer 14.

[0038] The detection rack 13 is used to simulate the interference source in the anti-interference test. In the conventional detection method, the detection rack 13 is arranged at equal angles along the edge area of ​​the detection machine 1 with the loading kit 12 as the center. For some antennas with unconventional structures, such as antenna signal generation range limited to a certain angle, the arrangement of the detection rack 13 can be formulated according to actual test requirements.

The support frame plate 22 is branched into a first interference frame 25 and a second interference frame 26 through a branch frame 24. The first interference frame 25 and the second interference frame 26 are both installed with interference members 27; the interference member 27 is the interference source for detecting the anti-interference degree of the antenna; the first adjustment roller 31 and the second adjustment roller 34 are designed in this embodiment as adjustment members, and the support directions of the first interference frame 25 and the second interference frame 26 are adjusted by pulling ropes from the upper and lower directions respectively, so as to adjust the interference angle of the interference member 27 to the antenna signal in the vertical direction, and the external rotation base 16 is a steerable structure, so that the signal interference direction can be simulated from various angles.

[0047] Preferably, in order to maintain the tension level, in this embodiment, a first direction-changing wheel 33 and a second direction-changing wheel 36 are respectively provided on the top of the detection frame 13 and the support frame plate 22, and the direction is changed by the first direction-changing wheel 33 and the second direction-changing wheel 36 respectively.

[0048] In one case of this embodiment,

[0049] During actual antenna operation, there may be interference sources caused by unexpected events. Such interference sources often appear around the antenna in irregular, shaky trajectories.

[0050] See also Figure 3 A plurality of tension springs 41 are arranged between the first interference frame 25 and the second interference frame 26 , a positioning base point 42 is arranged on the support frame plate 22 , and a buffer spring rope 43 is arranged between the positioning base point 42 and the frame of the branch frame 24 .

[0051] The present embodiment also designs that the branch frame 24, the first interference frame 25 and the second interference frame 26 are all installed through a movable shaft, and the first pull rope 32 and the second pull rope 35 provide tensioning force; during detection, the driving ends of the first adjustment roller 31 and the second adjustment roller 34 can be designed to be a reciprocating rolling structure, so as to cooperate with the buffering effect of the tension spring 41 and the buffer spring rope 43, so that the interference parts 27 on the first interference frame 25 and the second interference frame 26 form an irregular shaking trajectory, thereby effectively simulating a shaking interference source and detecting the anti-interference phenomenon of the antenna.

[0052] In one embodiment;

[0053] The specific implementation structure of the external rotation base 16 and the corresponding external drive assembly 18 is as follows:

[0054] See also Figure 4 and Figure 6 The detection machine 1 includes a supporting base 51 and a loading platform 52 fixedly mounted on the supporting base 51. The main body of the external rotating base 16 is a frame platform 53. The frame platform 53 is mounted on the supporting base 51 and rotates relative to the loading platform 52. An annular space 55 is formed between the frame platform 53 and the loading platform 52. The inner edge of the frame platform 53 is provided with an inner ring tooth pattern 54. The supporting base 51 is provided with an internal drive cavity 56. The internal drive cavity 56 is provided with a first internal drive motor 57. A drive shaft 58 is installed at the force output end of the first internal drive motor 57. The drive shaft 58 extends into the annular space 55 and is provided with an internal drive gear 59. The internal drive gear 59 is meshed with the inner ring tooth pattern 54.

[0055] The main body of the external rotating base 16 designed in this embodiment is a frame table 53, which is arranged at the outer frame position of the supporting base 51 and is rotatably installed; the inner edge of the frame table 53 is provided with an inner ring tooth pattern 54; this embodiment adopts a tooth-meshing internal drive method, with the first internal drive motor 57 as the driving end, driving the internal drive gear 59 to move, and the internal drive gear 59 extends to the annular space 55 formed between the frame table 53 and the loading table 52, and drives the external rotating base 16 to move through the tooth-meshing transmission, thereby driving the frame table 53 to move, and then driving the detection frame 13 mounted on the frame table 53 to move.

[0056] Regarding the driving method of the inner rotating base 17 and the corresponding inner driving component 19.

[0057] See also Figure 5 and Figure 6The inner rotating base 17 is arranged at the center line position of the loading platform 52, and the inner drive assembly 19 includes a center rotating shaft 62 for driving the inner rotating base 17, and a second inner drive motor 64 for driving the center rotating shaft 62; the center rotating shaft 62 is supported in the inner drive cavity 56, and a driven wheel 63 is installed on the center rotating shaft 62, and a driving wheel 65 is installed at the driving end of the second inner drive motor 64, and the driven wheel 63 and the driving wheel 65 are connected by a transmission belt 66.

[0058] This embodiment does not use a motor to directly drive the movement of the inner rotating base 17, but uses a median rotating shaft 62 as a supporting structure to support the inner rotating base 17 and the loading kit 12 mounted on the inner rotating base 17, and uses a second internal drive motor 64 as a driving end, which is connected to the transmission through a transmission belt 66, thereby indirectly driving the movement of the median rotating shaft 62, that is, driving the rotation adjustment of the antenna, thereby avoiding the vibration of the motor itself and the influence on the antenna, thereby avoiding the self-vibration of the motor affecting the precision of the detection data.
