Description

Active antenna testing method, device, terminal, system, equipment and storage medium

Technical Field

The present invention relates to the field of communication technology, and in particular to an active antenna testing method, device, terminal, system, communication equipment and storage medium.

Background technique

With the advent of the 5G era, massive MIMO (MM) antenna arrays are becoming more and more common in mobile communication networks. Unlike traditional passive base station antennas, the RF part and antenna part of MM are integrated together, and it is an active antenna (AAU). Based on this feature, the measurement of antenna parameters and some RF parameters of AAU needs to be performed in a microwave darkroom by spatial radiation (Over the Air, OTA). For antenna pattern and some omnidirectional RF indicators, it is necessary to measure the signal radiated by AAU in 360-degree direction. Therefore, AAU needs to be installed on the multi-dimensional turntable module. The turntable module is rotated to achieve omnidirectional testing. The test process includes: the turntable module starts to rotate from the starting angle to the ending angle. When it rotates to the next step angle, the turntable module stops and automatically sends a trigger signal to the spectrum meter through the wired connection to trigger the spectrum meter to start measurement; the spectrum meter starts to measure the signal radiated into space by the antenna under test obtained by the receiving antenna. The frequency sweep test takes a certain amount of time. After the test results are obtained, the test data is transmitted to the server, and then the server controls the turntable module to continue rotating to the next step angle, and triggers the spectrum meter to measure again. This cycle is repeated until the turntable module rotates to the ending angle and the test ends.

However, due to the wide operating frequency bandwidth (such as 160MHz, or even 200MHz) and signal bandwidth (such as sub6G maximum 100MHz, millimeter wave has 400MHz) of AAU equipment, and the traditional broadband signal measurement adopts the frequency domain scanning solution, the measurement time is in seconds, and the calculation is calculated at 0.2 degrees per point. The 360-degree directional diagram of each section requires 1,800 points, and the test time takes 30 minutes. Because OTA testing requires testing many RF indicators, the test time of 30 minutes/circle is unacceptable for OTA testing, especially for total radiated power (TRP) test indicators, resulting in low test efficiency of active antennas.

In the embodiments of the present invention, the term "and/or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Referring to FIG. 1 , FIG. 1 is a flow chart of an active antenna testing method provided by an embodiment of the present invention. As shown in FIG. 1 , the method includes the following steps:

Step 101: Receive a first signal sent by a turntable module, and send a first instruction to a signal receiving module according to the first signal, wherein the first signal includes angle information of the turntable module.

Specifically, before receiving the first signal sent by the turntable module, a trigger instruction needs to be sent to the turntable module to make the turntable module rotate. When the turntable module rotates through a certain angle, a first signal will be returned. The returned first signal contains the current angle information of the turntable module. After receiving the first signal returned by the turntable module, it is necessary to generate a first instruction based on the first signal and send the first instruction to the signal receiving module (generally speaking, it can be a spectrum meter). The first instruction of the signal receiving module starts to perform time domain measurement on the antenna under test to obtain the corresponding measurement result, or searches for the measurement result corresponding to the first instruction from all the measurement results saved by itself, and returns the measurement result.

Step 102: Control the signal receiving module and the receiving antenna to perform time domain measurement on the radiation signal sent by the antenna under test according to the first instruction, and obtain a measurement result of the antenna under test.

Specifically, before this, a configuration instruction needs to be sent to the signal receiving module to make the signal receiving module work in the time domain measurement mode. The antenna under test will send a radiation signal, and the receiving antenna can receive the radiation signal sent by the antenna under test in the direction directly opposite to it. When the antenna under test is in a certain working state (transmitting mode), the receiving antenna can receive the radiation signal. At the same time, the signal receiving module will receive an external trigger instruction sent by the antenna under test. After receiving the external trigger instruction, the signal receiving module will start to measure the radiation signal received by the receiving antenna, thereby obtaining the measurement result of the antenna under test, and at the same time, the angle information of the antenna under test will be obtained, and the measurement result will be associated with the angle information and saved.

Step 103: Receive the measurement result of the measured antenna corresponding to the angle information returned by the signal receiving module.

Specifically, after the signal receiving module obtains the measurement result, the signal receiving module will return the measurement result corresponding to the angle information according to the angle information in the first instruction. At the same time, the measurement result and the angle information also need to be saved locally for subsequent processing. When saving, the measurement result also needs to be associated with the angle information before saving. At this time, the turntable module does not slow down or wait, but continues to rotate and generates the first signal again. After receiving the first signal, the server sends the first instruction to the signal receiving module again to obtain the current measurement result. This cycle continues until the turntable module rotates to the preset stop angle. The signal receiving module transmits all the measurement results to the server for processing, completing a test process.

for example:

Before the test begins, the antenna under test is rotated to 180 degrees as the starting point of the test; the receiving antenna is connected to the receiving channel of the signal receiving module (usually a spectrum meter) through an RF jumper; when the server starts the test, it is first necessary to set the step information of the turntable module (such as 0.2 degrees) and the rotation speed information of the turntable module (such as 4 degrees/second); it is also necessary to set the test mode of the signal receiving module, which is set to the time domain measurement mode here, and the trigger mode is single measurement (this setting means that the signal receiving module will trigger the measurement only when it receives an external trigger command from the outside (here is the antenna under test)).

After the turntable module and spectrum meter are set up, the test starts, and the rotation command and configuration command are sent to the turntable module and the signal receiving module respectively. The turntable module starts to rotate after receiving the rotation command. After receiving the configuration command, the signal receiving module adjusts the working mode to the time domain measurement mode and prepares to obtain the measurement results. When the antenna under test starts to work normally, it will continuously send out trigger signals. The signal receiving module will continuously perform time domain measurements under the control of the trigger signal of the antenna under test, transform the collected full bandwidth signal into a frequency domain signal through fast Fourier transform, and then extract the power measurement results of different carriers in the frequency domain and save them on the signal receiving module. When obtaining the measurement results, the signal receiving module will obtain the angle information of the antenna under test, and when saving the measurement results, the measurement results will be associated with the angle information before saving. The turntable module starts to rotate from the starting angle to the ending angle. When rotating to the next step angle, the turntable module will automatically send a first signal to the server through a wired connection. The server sends a first instruction to the signal receiving module to control the signal receiving module to perform time domain measurement according to the first instruction, and return the measurement result value corresponding to the first instruction to the server, and mark the current turntable module angle position information. At this time, the turntable module does not slow down or wait, but continues to rotate to the next step angle and generates the first signal again. After receiving the first signal, the server sends an instruction to the signal receiving module again to retrieve the current test result. This cycle continues until the turntable module rotates to the end angle. The signal receiving module transmits all the test results to the server for processing, completing a test process.

The active antenna test method of the embodiment of the present invention comprises the following steps: a server (computer) receives a first signal sent by a turntable module, and sends a first instruction to a signal receiving module according to the first signal, wherein the first signal includes angle information of the turntable module; the signal receiving module and the receiving antenna are controlled according to the first instruction to perform time domain measurement on the radiation signal sent by the antenna under test, and obtain the measurement result of the antenna under test; and the measurement result of the antenna under test corresponding to the angle information returned by the signal receiving module is received. By realizing the non-stop measurement of the turntable module and the signal receiving module obtaining the measurement result by the time domain measurement method, the test speed and accuracy of the active antenna test can be improved, and the problem of low test efficiency of the active antenna caused by the frequency domain scanning scheme used in the broadband signal measurement in the prior art is solved.

Referring to FIG. 2 , FIG. 2 is a second flow chart of the active antenna testing method provided by an embodiment of the present invention. As shown in FIG. 2 , the method includes the following steps:

Step 201: Send a second instruction to the turntable module, wherein the second instruction includes preset rotation speed information and preset step information.

Specifically, a second instruction is sent to the turntable module, and the second instruction includes preset rotation speed information (such as 4 degrees/second) and preset step information (such as 0.2 degrees), so that the turntable module can rotate at the preset rotation speed information. When the turntable module rotates through a preset step information, it returns the first signal.

Step 202: Control the turntable module to rotate according to preset speed information.

Specifically, the turntable module is a platform that can rotate 360 degrees. The second instruction includes preset speed information and preset step information. When the turntable module receives the second instruction, it controls the turntable module to rotate at the preset speed information.

Step 203: Control the turntable module to return a first signal according to the preset step information.

Specifically, when the turntable module rotates at a preset speed information, the turntable module needs to return a first signal every time it rotates through a preset step information. The first signal contains the current angle information of the turntable module. For example, the initial angle of the turntable module is 29 degrees, the preset speed information is 4 degrees/second, and the preset step information is 0.2 degrees. When the angle of the turntable module is 29.2 degrees, the first signal is returned, and the angle information in the first signal is 29.2 degrees. The next time the first signal is returned is when the angle of the turntable module is 29.4 degrees.

Step 204 , receiving a first signal sent by the turntable module, and sending a first instruction to the signal receiving module according to the first signal, wherein the first signal includes angle information of the turntable module.

Specifically, the implementation method of this step can refer to the description in step 101, and to avoid repetition, it will not be repeated here.

Step 205: When the signal receiving module receives an external trigger instruction, the receiving antenna is controlled to receive the radiation signal sent by the antenna under test, wherein the external trigger instruction is sent by the antenna under test.

Specifically, since the antenna under test operates in time division duplex mode, the transmission and reception of its signals are performed in time division, and the measurement needs to be performed at the transmission moment of the antenna under test. Therefore, when the antenna under test is switched to the transmission mode, an external trigger command will be output. When the signal receiving module receives this command, it will control the receiving antenna to receive the radiation signal sent by the antenna under test.

Step 206: Control the signal receiving module to perform time domain measurement on the radiation signal received by the receiving antenna to obtain a measurement result of the antenna under test.

Specifically, the signal receiving module can start to obtain the measurement result only when it receives the external trigger instruction sent by the antenna under test after receiving the first instruction. As shown in FIG. 3 , step 206 specifically includes:

Step 301: perform time domain measurement on the radiation signal received by the receiving antenna to obtain a full bandwidth signal.

Specifically, when the signal receiving module receives an external trigger command, it can obtain the full bandwidth signal (time domain signal) of the antenna under test through the time domain measurement method. The time domain measurement method is a working mode of the signal receiving module (spectrum meter). In this mode, a central frequency point is set to perform high-speed analog-to-digital conversion acquisition on the signal. It can also collect ultra-wideband signals at the same time, obtain the information of the full bandwidth signal at one time, and output it in the form of a digital signal. This test mode is generally used when analyzing the time domain characteristics of the modulated signal, and can view the edge, envelope and other characteristics of the signal.

Step 302: Perform fast Fourier transform on the full bandwidth signal to obtain a frequency domain signal.

Specifically, the full-bandwidth signal is subjected to a fast Fourier transform in the control signal receiving module, and the full-bandwidth signal of the time domain signal is converted into a frequency domain signal.

Step 303: Obtain measurement results according to the frequency domain signal.

Specifically, the power measurement results of different carriers in the frequency domain are extracted from the frequency domain signal and saved in the signal receiving module. When obtaining the measurement results, the signal receiving module obtains the angle information of the antenna under test, and when saving the measurement results, the measurement results are associated with the angle information before being saved.

Step 207: Receive the measurement result of the antenna under test corresponding to the angle information returned by the signal receiving module.

Specifically, the implementation method of this step can refer to the description in step 103, and to avoid repetition, it will not be repeated here.

This implementation can also be applied to the embodiment corresponding to FIG. 1 to achieve the same beneficial effects. In addition, the measurement results can be obtained only when two conditions are met, so as to further improve the accuracy of obtaining the measurement results.

Referring to FIG. 4 , FIG. 4 is a flowchart of the active antenna testing method provided by an embodiment of the present invention. As shown in FIG. 4 , the method includes the following steps:

Step 401: If a first signal is received, a first instruction is sent to a signal receiving module; if the first signal cannot be received, a first instruction is sent to the signal receiving module at a preset time interval.

Specifically, after sending the second instruction to the turntable module, it is necessary to detect whether the first signal returned by the turntable module can be received within the preset time. If the first signal can be received, the first instruction is sent to the signal receiving module according to the first signal. If the first signal cannot be received, it means that the turntable module cannot return the first signal, and it is necessary to adopt a backup plan to send the first instruction to the signal receiving module, wherein the preset time is determined according to the preset speed information and the preset step information in the second instruction. For example, when the preset speed information is 4 degrees/second and the preset step information is 0.2 degrees, it means that a first signal needs to be returned every 50 mm, and the preset time is 50 milliseconds.

Specifically, for a turntable module that cannot send the first signal to the control server as required, the preset time can be configured according to the rotation speed information and step information of the turntable module to automatically send instructions to the signal receiving module. At this time, the server does not need to first know whether the turntable module has rotated to the next step, but judges the current angle information of the turntable module according to the setting of the test speed. For example: when the initial angle of the turntable module is 29 degrees, the preset rotation speed information is 4 degrees/second, and the preset step information is 0.2 degrees, it means that a first signal needs to be returned every 50 mm, and the preset time is 50 milliseconds. If the first signal is not received in the first 50 milliseconds, the server judges that the current angle information of the turntable module is 29.2 degrees according to the number of times the preset time has passed (the first time), the rotation speed information of the turntable module, and the step information of the turntable module, and sends the first instruction to the signal receiving module according to the angle information.

Step 402: Control the signal receiving module and the receiving antenna to perform time domain measurement on the radiation signal sent by the antenna under test according to the first instruction, and obtain the measurement result of the antenna under test.

Specifically, the implementation method of this step can refer to the description in step 102, and to avoid repetition, it will not be repeated here.

Step 403: Receive the measurement result of the measured antenna corresponding to the angle information returned by the signal receiving module.

Specifically, the implementation method of this step can refer to the description in step 103, and to avoid repetition, it will not be repeated here.

for example:

Before the test begins, the antenna under test is rotated to 180 degrees as the starting point of the test; the receiving antenna is connected to the receiving channel of the signal receiving module (usually a spectrum meter) through an RF jumper; when the computer starts the test, it is first necessary to set the step information of the turntable module (such as 0.2 degrees), the rotation speed information of the turntable module (such as 4 degrees/second) and the preset time of 50 mm; it is also necessary to set the test mode of the signal receiving module, which is set to the time domain measurement mode here, and the trigger mode is single measurement (this setting means that the spectrum meter will only trigger the measurement when it receives an external trigger command from the outside (here is the antenna under test)).

After the turntable module and the signal receiving module are set up, the test starts, and the rotation command and configuration command are sent to the turntable module and the signal receiving module respectively. The turntable module starts to rotate after receiving the rotation command. After receiving the configuration command, the signal receiving module adjusts the working mode to the time domain measurement mode and prepares to obtain the measurement results. When the antenna under test starts to work normally, it will continuously send out trigger signals. The signal receiving module will continuously perform time domain measurements under the control of the trigger signal of the antenna under test, transform the collected full bandwidth signal into a frequency domain signal through fast Fourier transform, and then extract the power measurement results of different carriers in the frequency domain and save them on the signal receiving module. When obtaining the measurement results, the signal receiving module will obtain the angle information of the antenna under test, and when saving the measurement results, the measurement results will be associated with the angle information before saving. The turntable module starts to rotate from the starting angle to the ending angle, and the server sends the first command to the signal receiving module every preset time of 50 milliseconds, and the server sends the first command to the signal receiving module to control the signal receiving module to perform time domain measurement according to the first command, and return the measurement result value corresponding to the first command to the server, and mark the current turntable module angle position information. At this time, the turntable module does not slow down or wait, but continues to rotate to the next step angle and generates a trigger signal again. After receiving the trigger signal, the server sends an instruction to the signal receiving module again to retrieve the current test result. This cycle continues until the turntable module rotates to the end angle. The signal receiving module transmits all the test results to the server for processing, completing a test process.

This implementation can also be applied to the embodiment corresponding to FIG. 1 to achieve the same beneficial effects, and can also send the first instruction to the signal receiving module in a time interval, so that the applicability of the present invention is higher and the application range is wider.

Referring to FIG. 5 , FIG. 5 is a fourth flow chart of the active antenna testing method provided by an embodiment of the present invention. As shown in FIG. 5 , the method includes the following steps:

Step 501: Receive a first signal sent by a turntable module, and send a first instruction to a signal receiving module according to the first signal, wherein the first signal includes angle information of the turntable module.

Specifically, the implementation method of this step can refer to the description in step 101, and to avoid repetition, it will not be repeated here.

Specifically, after obtaining the measurement result, it is necessary to determine whether the angle information corresponding to the measurement result reaches the preset stop angle information, which is the preset stop angle information of the turntable module. After the turntable module reaches the preset stop angle information, it will no longer rotate, so that the antenna under test also stops rotating; if the preset stop angle information of the turntable module is reached, execute step 505; if the preset stop angle information of the turntable module is not reached, execute step 501 until the angle information reaches the preset stop angle information.

Step 505, stop sending the first instruction to the signal receiving module.

Specifically, when the current angle information of the turntable module reaches the preset stop angle information of the turntable module, it means that the measurement results of all angles of the antenna under test have been obtained, and the turntable module has stopped rotating, the test process has ended, and it is necessary to stop sending the first instruction to the signal receiving module.
