Description

Technical Field

[0001] The present invention relates to the field of microwave signal testing technology, and in particular to a test device for quality inspection of 5G communication equipment. Background Art

[0002] 5G microwave base station is a signal transmission base station that uses microwave communication technology. Microwave communication is the use of microwaves to transmit information. The propagation characteristics of microwaves determine that the main mode of microwave communication is line-of-sight communication. After exceeding line-of-sight, relay forwarding is required, so microwave communication is also called microwave relay communication or microwave relay communication. Generally speaking, due to the influence of the earth's curvature and the loss of microwave transmission, a relay station (collectively referred to as a microwave station) needs to be set up every 50 kilometers or so to amplify and forward the radio waves to extend them;

[0003] The millimeter wave frequency band has abundant spectrum resources and can fully support the needs of 5G communication. Millimeter wave communication is a type of microwave communication, which uses microwave frequencies ranging from 30GHz to 300GHz and wavelengths ranging from 1mm to 10mm. Compared with the decimeter wave band used by 4G, its frequency is higher and its wavelength is shorter, so its scattering and diffraction capabilities are relatively poor. Therefore, millimeter wave transmission is closer to optical transmission and mainly relies on line-of-sight paths for transmission. In addition, millimeter wave antennas have narrow beams and good directivity, but they are also more easily reflected or blocked. Furthermore, in the process of free space propagation, the atmosphere, rainfall, etc. will cause serious absorption losses to millimeter wave transmission. According to the principle of free space transmission loss of radio waves, the higher the frequency of the radio wave, the more serious the attenuation will be on its transmission path.

[0004] Based on this, when installing 5G base stations on installation paths with different obstacles, the required relay station distances are different. Considering the installation cost and transmission signal reliability, it is necessary to detect the propagation loss rate of microwave signals in different medium paths to ensure reliable signal transmission at the lowest cost. Based on this, a test equipment for quality inspection of 5G communication equipment is proposed. Summary of the invention

[0033] Example, see Figures 1 to 8A test device for quality inspection of 5G communication equipment includes a test platform 1 for testing 5G communication equipment. The 5G communication equipment includes a microwave transmitter and a microwave receiver. The microwave transmitter and the microwave receiver are both 5G communication base station microwave communication equipment. They are existing technologies and will not be described in detail here.

[0034] An installation test bench 2 is provided at the center of the test platform 1. The installation test bench 2 is a structure for installing a microwave transmitter. Reflection test units are provided around the installation test bench 2. Reflection extension test units that can be lifted and adjusted are provided outside the reflection test units.

[0035] A plurality of sets of static simulation devices and dynamic simulation devices are arranged inside the reflection test unit to simulate the change of energy intensity when microwaves pass through, and the microwave transmitter is installed on the installation test bench 2 through an adjustable component;

[0036] Furthermore, the adjustable component includes a combination port opened on the installation test bench 2, the inner wall of the combination port is rotatably connected to a clamping plate 17 through a rotating shaft 16, and a threaded clamp is provided on the clamping plate 17. The threaded clamp can achieve a structure that fixes the microwave emitter installed on the clamping plate 17 by rotating the threaded rod, so as to ensure that when the angle of the clamping plate 17 is adjusted, the microwave emitter can be driven to rotate. An adjustment motor 18 is provided on the installation test bench 2, and the output end of the adjustment motor 18 is connected to the rotating shaft 16 through a worm gear.

[0037] Among them, a transmission cavity is opened inside the installation test bench 2, and the worm gear parts include an adjusting worm wheel connected to the output end of the adjusting motor 18. The end of the rotating shaft 16 passes through the transmission cavity and is fixedly connected to an adjusting worm gear meshing with the adjusting worm wheel. The one-way self-locking function between the worm gear parts can ensure that the angle of the adjusted microwave transmitter is fixed.

[0038] The microwave receiver is detachably mounted in the reflection extension test unit through the U-shaped fixing component 3, and the microwave signal transmitted between the microwave transmitter and the microwave receiver is connected through multiple reflections and simulated obstacles.

[0039] The inner test cover and the reflection extension cover are both provided with assembly openings for installing the U-shaped fixing component 3, which are reasonably controlled according to the test items and the reflection length required for the test. It should be noted that the direction of the assembly opening is perpendicular to the microwave incident angle, so that the microwaves of the test can be absorbed by the microwave receiver arranged on the U-shaped fixing component 3.

[0040] It should be noted that the U-shaped fixing component 3 can be provided with corresponding fixing grooves according to the specific structure of the microwave receiver. The angle of the microwave receiver does not need to be adjusted during the test phase, so the microwave receiver can achieve the purpose of testing at a fixed angle.

[0041] The reflection test unit comprises an inner test housing, which is composed of a hexagonal inner shielding plate 4 and an inner cover plate 5;

[0042] The inner shielding plate 4 is provided with a through hole for microwaves to penetrate from the inner test cover to the reflective extension cover.

[0043] The inner wall of the inner shielding plate 4 is provided with a metal reflector 6 for reflecting microwaves. The angle of the first metal reflector 6 needs to ensure that the microwave signal of the transmitter on the middle installation test bench 2 can be reflected to the metal reflector 6 on the inner shielding plate 4.

[0044] The metal reflection plate 6 and the metal reflection extension plate 11 are both made of good conductor metals with strong microwave reflection capability in the range of 30 GHz to 300 GHz, and can achieve the effect of microwave reflection.

[0045] In this scheme, the properties of good conductor metal are similar to those of ideal conductors. When microwaves are projected onto the surface of a good conductor, total reflection can be considered to occur. If microwaves encounter obstacles during propagation, they will definitely be reflected. Microwaves follow the law of reflection during the reflection process, that is, the reflected line is on the plane determined by the incident line and the normal through the incident point. The reflected line and the incident line are separated on both sides of the normal, and the reflection angle is equal to the incident angle. Therefore, the reflection principle can be used to achieve the effect of extending the test distance and realizing multiple simulations.

[0046] The metal reflection plate 6 and the metal reflection extension plate 11 are both connected to each other in an angle-adjustable rotation manner via a vertical rotation axis 20 , so that the corresponding angles can be adjusted according to the required angles to ensure the microwave reflection effect.

[0047] The reflection extension test unit includes a safety protection cover 8 connected by a lifting device. The safety protection cover 8 is a shielding metal layer that can absorb microwaves to prevent them from escaping and causing harm to test personnel. A reflection extension cover is rotatably provided on the inner wall of the safety protection cover 8. The reflection extension cover consists of a hexagonal outer shielding plate 9 and an outer cover plate 10. The inner wall of the outer shielding plate 9 is provided with a metal reflection extension plate 11.

[0048] It should be noted that, in the present solution, a rotational connection is arranged between the safety protection cover 8 and the reflective extension cover, which enables the rotational adjustment of the reflective extension cover, thereby enabling the position of the microwave receiver arranged thereon to be reasonably adjusted according to the required reflection distance and test ratio, thereby enabling the installed microwave receiver to stop at any position of the hexagonal outer shielding plate 9, thereby meeting more requirements of the test items.

[0049] A plurality of mounting openings 7 for mounting static simulation devices and dynamic simulation devices are formed on the inner cover plate 5 and the outer cover plate 10 , and a shielding mounting cover plate 12 is disposed on the mounting openings 7 .

[0050] The static simulation device includes a mounting frame 13 made of glass material, a glass plug-in box 14 is arranged in the mounting frame 13, and a variety of simulation materials are arranged in the glass plug-in box 14. The mounting frame 13 is provided with a plug-in interface for installing the glass plug-in box 14.

[0051] The dynamic simulation device includes a glass simulation cylinder 15 installed in the installation port 7, and a fog simulation module and a rain simulation module are arranged inside the glass simulation cylinder 15. The fog simulation module can be controlled by a sprayer, and the rain simulation module can be controlled by a spray device to simulate the influence of the natural environment.

[0052] The lifting device includes a support seat fixedly arranged on the outer side wall of the installation protection cover body. A hydraulic cylinder 19 is arranged on the test platform 1, and the output end of the hydraulic cylinder 19 is fixedly connected to the support seat.

[0053] When testing the 5G base station microwave signal communication equipment, the present invention installs the microwave transmitter on the installation test bench 2, and clamps the microwave transmitter by the clamping plate 17 on the installation test bench 2 to achieve effective fixation; at this time, according to the number of simulation items to be tested, the microwave receiver is installed on the reflective extension cover (farther) and the inner test cover (closer), and the microwave receiver is installed on the U-shaped fixing component 3, and then the U-shaped fixing component 3 is installed on the assembly port;

[0054] According to the model of the actual installation process of the 5G base station, a static simulation device is established by scaling down in proportion to simulate the transmission loss rate of microwaves in different media during the actual propagation process, such as building obstruction, steel structure obstruction, forest trees and rocks, etc. According to actual needs, different simulation materials are installed in the glass plug box 14, and the simulation materials are placed in the installation frame 13 accordingly to achieve the establishment of a static simulation device, and explore the transmission loss rate of microwaves in different media, so as to explore whether the signal reception can be guaranteed in the actual installation of the 5G base station;

[0055] In this process, when the influence of the natural dynamic environment on the microwave signal is simulated according to different environmental needs, the test can be carried out in the glass simulation cylinder 15 according to the environmental simulation to be explored;

[0056] After the preparation is complete, the microwave transmitter is turned on, and the microwave receiver receives the microwave signal at the corresponding position to be detected. According to the volatility of signal transmission and the strength of the final received signal, the attenuation and loss of the microwave signal in the transmission path are explored, so as to obtain the test experiment when the 5G microwave base station is established through the simulated environment, so as to ensure the establishment of the 5G base station at the lowest cost while ensuring the reliability of the transmission signal.

[0057] During this detection process, when it is necessary to deal with the impact of the mismatch between the microwave emission angle and the receiving angle on the signal, the worm gear can be controlled by adjusting the motor 18 to fine-tune the angle of the clamping plate 17, thereby changing the emission angle of the microwave transmitter to explore the impact of the angle on the reception of microwave signals.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
