Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following first describes an antenna performance detection method provided by the embodiment of the present invention.
It should be noted that, the antenna performance detection method provided by the embodiment of the invention relates to the technical field of antenna detection, and can be widely applied to an antenna performance detection system. The method may be performed by the antenna performance detection apparatus of the embodiment of the present invention. The antenna performance detecting device may be configured in any first electronic device to perform the antenna performance detecting method, where the first electronic device may be a server or a terminal, and is not limited herein specifically.
The method is applied to a first electronic device, and referring to fig. 1, a flow diagram of an antenna performance detection method provided by an embodiment of the present invention is shown in the figure. As shown in fig. 1, the method may include the steps of:
Step 101, controlling an antenna in the second electronic device to transmit a first continuous signal in a preset frequency band.
In this embodiment, the method may be applied to an antenna performance detection system, and referring to fig. 2, fig. 2 is a schematic structural diagram of the antenna performance detection system, and as shown in fig. 2, the first electronic device 201 may be a part of the antenna performance detection system, and the antenna performance detection system may further include a second electronic device 202 and N third electronic devices 203, where N is an integer greater than 1.
The first electronic device may be referred to as a test controller in the antenna performance detection system, and may be a computer or other terminal capable of installing test control software, which may control an antenna in the second electronic device to send a first continuous signal, and N third electronic devices may receive the first continuous signal through the antenna, detect signal strength thereof, and send it to the first electronic device. Correspondingly, the first electronic device may receive the signal strength values sent by the N third electronic devices, and evaluate the antenna performance in the second electronic device based on the received signal strength values.
The second electronic device may be referred to as a device to be detected (Device Under Testing, DUT) in the antenna performance detection system, and may be an internal antenna, where the antenna may be a new generation antenna such as a fifth generation 5G antenna, and in the case that the second electronic device is internally provided with a 5G antenna, the second electronic device may be a 5G terminal. That is, the frequency range of the signal transmitted by the antenna of the second electronic device may be a frequency range of a New air interface (NR) of 5G, where the frequency ranges of 5 GNRs are respectively defined as different frequency ranges FR, respectively, a frequency range FR1 and a frequency range FR2, the frequency range FR1 is generally referred to as a frequency band of 5G Sub-6GHz (i.e. below 6GHz, 450MHz to 6000 MHz), and the frequency range FR2 is a frequency band of 5G millimeter waves (i.e. 24250MHz to 52600 MHz).
The third electronic device may be referred to as a signal detector in the antenna performance detection system, and may be an internal antenna, which may be a 5G full band antenna, so as to receive a signal sent by the second electronic device. And, the third electronic device may detect the received signal to determine the signal strength. The signal detectors may be arranged in a plurality of positions according to the need and distributed at different positions, so as to detect the signal intensity distribution in all directions within the coverage area of the antenna of the second electronic device.
The first electronic device and the second electronic device can be connected in a wired mode through a serial port, can be connected in a wireless mode through wireless fidelity (WIRELESS FIDELITY, WIFI), and can transmit data to the second electronic device through the connection of the first electronic device. The second electronic device may have an antenna built in each of the third electronic devices, and the signals may be transmitted through the antenna. The first electronic device and the third electronic device can be connected in a wired mode through a serial port, can be connected in a wireless mode through WIFI, and can be in two-way communication with the third electronic device through connecting the first electronic device so as to transmit data.
The N third electronic devices are located in N directions of the second electronic device, where the N directions may be different directions, i.e. the N third electronic devices are located in different azimuth angles of the first electronic device, respectively.
The antenna performance detection system needs to meet two conditions before implementation, namely, the first electronic equipment can control the antenna of the second electronic equipment to fix frequencies in a specified frequency band and send continuous signals in the specified frequency band; the other is that the signal strength of the test environmental noise is significantly smaller than the signal strength when the first electronic device transmits a continuous signal.
The preset frequency band may be a specified frequency band within a 5G frequency range, for example, 600MHz to 960MHz, 1720MHz to 2170MHz, 4400MHz to 5850MHz, and the like. The first electronic device may send an instruction to the second electronic device, where the instruction is used to control an antenna in the second electronic device to send the first continuous signal in a preset frequency band, and the instruction may carry the preset frequency band. Correspondingly, the second electronic device can enter an antenna test mode under the condition of receiving the instruction, and in the antenna test mode, the antenna of the second electronic device can be fixed in a preset frequency band, and a carrier signal, namely a first continuous signal, is sent on the preset frequency band.
Step 102, receiving N first target signal strength values sent by N third electronic devices, where the N third electronic devices are located in N directions of the first electronic device, and the first target signal strength value sent by each third electronic device is a signal strength value on the preset frequency band detected by the third electronic device based on the first continuous signal.
Wherein N is an integer greater than 1.
In this step, the third electronic device may receive the first continuous signal sent by the second electronic device through the built-in antenna, and detect the signal strength of the first continuous signal, where the detected signal strength may reflect the strength of the transmitted signal of the second electronic device, so as to reflect the antenna performance of the second electronic device.
The third electronic device may send the detected first target signal strength value to the first electronic device, and correspondingly, the first electronic device may receive N first target signal strength values sent by the N third electronic devices.
The third electronic device may be placed in a different direction, the detected first target signal strength value may be different, and the third electronic device may be different from the second electronic device in distance, and the detected first target signal strength value may also be different.
Therefore, to ensure the accuracy of the test, a measurement environment needs to be set up fixedly so that different second electronic devices are placed in the environment system, and the influence of the second electronic devices is the same.
In an alternative embodiment, referring to fig. 3, fig. 3 is a schematic view of a test environment of an antenna performance detection system, as shown in fig. 3, a device 301 to be detected may be placed in a designated area 302 on a wooden table, where the direction in which the device 301 to be detected is placed is consistent with a requirement, and there is no shielding object that affects wireless signal transmission around, the height of the wooden table top is about 0.8 meter from the ground, and the test controller 303 is placed aside, preferably without affecting transmission of 5G signals. The more signal detectors 304 are placed in each direction of the device 301 to be detected, the more comprehensive the signal coverage test is, and in this embodiment, 3 signal detectors are set for example.
The distance between the signal detector 304 and the device 301 to be detected is about 2 meters, and specific values can be properly adjusted according to different test environments, so that the signal intensity received by the signal detector is ensured to be obviously greater than the signal intensity of environmental noise when the device 301 to be detected sends continuous carrier signals.
And step 103, determining the first-day linear energy score value corresponding to each first target signal strength value, and obtaining N first-day linear energy score values.
In this step, for each first target signal strength value, the first electronic device may determine a first day linear energy score value corresponding to the first target signal strength value according to a preset function, or may determine an antenna performance score value corresponding to the first target signal strength value based on a target correspondence, which is not specifically limited herein.
In an alternative embodiment, the antennas are directional, and each antenna also has a certain interference with each other, and the signal strength received by each third electronic device in the antenna radiation range of the second electronic device may also be different. Thus, for each direction, a target correspondence of signal strength values to antenna performance score values may be determined.
For example, for a third electronic device facing the second electronic device, in a normal case, when the signal strength value reaches 100, it may be determined that the antenna performance of the second electronic device is acceptable, and when the current linear energy score value is greater than or equal to 80, it may be set that the antenna performance of the second electronic device is acceptable. Therefore, there may be a target correspondence, when the signal strength value is greater than 100, the antenna performance score value is greater than 80 points, and when the signal strength value is less than 100, the antenna performance score value is less than 80 points, and when the signal strength value is equal to 100, the antenna performance score value is equal to 80 points, and as for the specific score, it may be set according to the actual situation, without being specifically limited thereto.
For another example, for a third electronic device diagonally opposite to the second electronic device, in a normal case, when the signal strength value reaches 80, it may be determined that the antenna performance of the second electronic device is qualified, and when the current linear energy score value is greater than or equal to 80, it may be set that the antenna performance of the second electronic device is qualified. Therefore, there may be another target correspondence, when the signal strength value is greater than 80, the antenna performance score value is greater than 80, and when the signal strength value is less than 80, the antenna performance score value is less than 80, and when the signal strength value is equal to 80, the antenna performance score value is equal to 80, and as for the specific score, it may be set according to the actual situation, without being specifically limited thereto.
And step S014, carrying out weighting processing on the N first day linear energy score values based on the first weight information corresponding to the N directions to obtain the target score value of the antenna.
In this step, because the usage scenario of the second electronic device is different, the performance requirements of the antenna of the second electronic device in each direction may be different, for example, in general, the requirements of the carrier signal transmitted by the antenna of the second electronic device in the opposite direction are strict, that is, the signal strength transmitted in the opposite direction is better, otherwise, the performance requirements of the antenna cannot be met, and the signal strength transmitted in other directions may be slightly lower than the opposite direction. Therefore, according to the performance requirements of the antenna of the second electronic device in different directions, different weights can be preset to obtain first weight information corresponding to the N directions, and the first weight information can be stored in the first electronic device in advance.
Thus, for each first day linear energy score value, there is a weight corresponding to the direction, and based on the first weight information corresponding to the N directions, the N first day linear energy score values are weighted, where the formula of the weighting is as shown in the following formula (1):
Wherein S j is a performance composite score of the antenna of the second electronic device in the jth preset frequency band with respect to the N directions, y i is a first day linear energy score value based on the antenna of the second electronic device detected by the third electronic device in the ith direction, and β i is a weight corresponding to the ith direction.
And under the condition that the performance of the antenna of the second electronic device in one preset frequency band is only detected, the performance composite score of the antenna of the second electronic device in the preset frequency band in the N directions is the score value of the antenna of the second electronic device.
In an alternative embodiment, since the 5G frequency band range is too wide and is divided into frequency bands, all frequency bands from 450MHz to 6000MHz are included below 6GHz, the antenna performance of a plurality of preset frequency bands within the 5G frequency band range can be measured to comprehensively evaluate the antenna performance of the 5G antenna.
If the antenna performance of the antenna of the second electronic device in a plurality of preset frequency bands needs to be detected, the performance integrated scores of the antenna of the second electronic device in different preset frequency bands in the N directions can be repeatedly measured to obtain a plurality of performance integrated score values, and the target score value of the antenna of the second electronic device is finally determined based on the plurality of performance integrated score values.
That is, the number of the preset frequency bands is M, where M is an integer greater than 1, and the weighting processing is performed on the N first day linear energy score values based on the first weight information corresponding to the N directions to obtain a target score value of the antenna, including:
For each preset frequency band, weighting the N first day linear energy score values based on the first weight information corresponding to the N directions to obtain M second antenna performance score values;
and weighting the M second antenna performance score values based on the second weight information corresponding to the M preset frequency bands to obtain target score values of the antennas.
In the actual detection process, after obtaining the performance comprehensive scores of the N directions on one preset frequency band, the first electronic device can send another instruction to the second electronic device, the instruction instructs the second electronic device to switch to another preset frequency band to send a carrier signal, and the second electronic device switches to another preset frequency band to send the carrier signal after receiving the instruction, so that the detection is repeated.
And for each preset frequency band, weighting the N first day linear energy score values based on the first weight information corresponding to the N directions to obtain a performance comprehensive score value, namely a second antenna performance score value, and obtaining M second antenna performance score values after all the preset frequency bands are detected.
And then, weighting the M second antenna performance score values based on the second weight information corresponding to the M preset frequency bands to finally obtain the target score value of the antenna.
It is known from antenna theory that it is impossible or cost-effective to maintain good performance in a very large frequency band, and in a real usage scenario, most frequency bands are often used very little or not used at all, so that, in combination with the actual usage scenario of the second electronic device, the antenna performance of the important usage frequency band can be designed to be optimal, and other unused frequency bands are omitted, namely, the weight setting corresponding to the preset frequency band that is frequently used is relatively large, and the weight setting corresponding to the preset frequency band that is not frequently used is relatively small.
Thus, for each second antenna performance score value, there is a weight corresponding to the preset frequency band, and based on the second weight information corresponding to the M preset frequency bands, weighting is performed on the M second antenna performance score values, where the formula of the weighting is shown in the following formula (2):
S T is a target score value of the antenna of the second electronic device, and alpha j is a weight corresponding to the j-th preset frequency band.
Therefore, the performance comprehensive score of the antenna of the second electronic device can be calculated by comprehensively considering different frequency bands and different directions, and the detection effect of the antenna performance can be improved.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a signal detector in the antenna performance detection system, where the signal detector can detect signal intensities of continuous signals sent by equipment to be detected on different preset frequency bands respectively, and as shown in fig. 4, the signal detector can be composed of a 5G full-band receiving antenna, a radio frequency gating switch, a band-pass filter, a detection amplifying circuit, an analog-to-digital AD converter, a micro control unit (Microcontroller Unit, MCU) control module, a WIFI module and an RS485 serial port.
The 5G full-band receiving antenna can receive all frequency bands in the 5G frequency range, for example, can receive wireless signals in the range of 600 MHz-6000 MHz.
A radio frequency gating switch: and the signals received by the 5G full-band receiving antenna are selectively connected with one path of the band-pass filters (S1-S5) under the control of the MCU control module.
Band pass filters (S1 to S5): only the signals in the frequency band are allowed to pass through, and the signals outside all other frequency bands are filtered.
Detection amplifying circuits (1-5): the radio frequency carrier signal is converted into a voltage signal, and the voltage signal is amplified and then input to the AD converter.
AD converter: and converting the analog voltage signal into a digital signal, and transmitting a detection result, namely a signal intensity value, to the MCU control module.
MCU control module: is a control center of the signal detector, and mainly realizes the following control functions: responding to the instruction sent by the test controller to control the radio frequency gating switch; controlling a radio frequency gating switch to enable signals received by a 5G full-band receiving antenna to flow into a designated channel; and reading the analog-to-digital conversion result from the AD converter to obtain a signal intensity value.
WIFI module: and the wireless communication function with the test controller is realized.
RS485 serial port: and realizing the limited communication function with the test controller.
Step S105, evaluating the performance of the antenna based on the target score value.
One or more evaluation thresholds may be set to evaluate the performance of the antenna based on the target score value, and in an alternative embodiment, two thresholds may be set, a second threshold and a third threshold, respectively. The evaluating the performance of the antenna based on the target score value includes:
Determining that the performance of the antenna is qualified when the target score value is greater than or equal to a second threshold value;
