The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the invention.
The antenna testing method of the electronic equipment can be applied to the process of assembling the antenna of the electronic equipment such as a computer, a router, a mobile phone and the like, and can specifically and accurately judge whether the assembly of the antenna meets the assembly standard.
Fig. 1 is a flowchart of an antenna testing method of an electronic device according to an embodiment of the present invention, and as shown in fig. 1 in conjunction with fig. 3 and 5, the antenna testing method includes the following steps:
s1, a first test signal is generated according to the trigger command.
The trigger instruction may be generated after a preset condition is met, and in one embodiment, the electronic device may generate the trigger instruction after entering a detection mode and starting detection, for example, the electronic device runs a self-check program and enters a factory mode to generate the trigger instruction; in another embodiment, the user may actively issue the trigger command, such as operating the electronic device to generate the trigger command according to an actual test situation. The electronic equipment generates a first test signal according to the trigger instruction. The first test signal may particularly be generated by a specific component in the electronic device, such as a processing module. The first test signal is used for detecting the assembling condition of the antenna. The signal characteristic of the first test signal may be determined based on a device characteristic of the electronic device and a communication requirement of the antenna.
S2, sending out the first test signal through a first antenna component of the electronic device.
The first antenna assembly may include a first antenna body and a first signal adjusting device, where the first signal adjusting device may adjust a signal characteristic of the first test signal, and in an embodiment, the first signal adjusting device may adjust the first test signal according to a communication requirement when the electronic device is actually used, for example, adjust a signal frequency and a signal intensity, so that the adjusted first test signal is close to or equal to a signal sent by the first antenna assembly when the electronic device is actually used, and of course, adjustment information for adjusting the first test signal may be acquired by the electronic device, and particularly, may be acquired by a processing module in the electronic device, so as to be used later. The signal characteristic of the first test signal is adjusted and then emitted out through the first antenna body to radiate outwards.
S3, receiving the first test signal through a second antenna component of the electronic device, forming a corresponding second test signal.
The second antenna assembly is also one of the electronic devices, creating a situation where the electronic device itself transmits a signal and has itself received it. In this embodiment, the first test signal is received by the second antenna assembly in a wireless manner, and since the first test signal is lost during transmission, in this embodiment, the received first test signal may be adjusted, for example, the signal frequency and the signal strength may be adjusted, so as to form a corresponding second test signal, of course, the adjustment information for adjusting the first test signal may be acquired by an electronic device (for example, a processing module in the electronic device) for subsequent use, and the formed second test signal may be used to evaluate the first test signal.
S4, comparing the first characteristic information of the first test signal with the second characteristic information of the second test signal to form a corresponding comparison result.
The first characteristic information includes information of a characteristic of the first test signal when the first test signal is generated, and also includes information of a characteristic of the first test signal after the first test signal is adjusted. The first characteristic information represents signal characteristics of the first test signal, including information such as a signal frequency, a signal strength, and the like of the first test signal. Similarly, the second characteristic information includes characteristic information of the second test signal when the second test signal is formed, and information of characteristics of the second test signal after the second test signal is subjected to signal conditioning. The second characteristic information represents signal characteristics of the second test signal, including information such as signal frequency, signal strength, etc. of the second test signal. The comparing of the first characteristic information with the second characteristic information may be comparing at least one characteristic point in the characteristic information, such as comparing signal strength.
The specific implementation of the comparison operation can be realized through one device in the electronic device, for example, the processing module in the electronic device, so that the processing module can send the first test signal, can receive the second test signal, and can also compare the first test signal with the second test signal, for example, the processing unit in the processing module is utilized to compare the operation, so that the comparison result can be obtained more conveniently and accurately. Preferably, the characteristics of the first test signal when the first test signal is generated may be compared with the characteristics of the received second test signal one by one. And forming a corresponding comparison result.
S5, determining whether the first antenna component and/or the second antenna component meets a predetermined assembly requirement if the comparison result meets a predetermined specification.
The preset regulation can be specifically set according to the production requirement of the electronic equipment and the requirements in practical application scenes such as the preset communication standard of the antenna, and if the comparison result meets the preset regulation, the first antenna assembly and the second antenna assembly can be determined to meet the preset assembly requirement without modifying the assembly operation of the first antenna assembly and the second antenna assembly; if the comparison result does not meet the preset regulation, the first antenna assembly and/or the second antenna assembly are considered not to meet the preset assembly requirement, and the first antenna assembly and the second antenna assembly can be further detected respectively, so that the antenna assembly is determined not to meet the preset assembly requirement. Of course, in the actual production process, the first antenna assembly and the second antenna assembly are in accordance with the preset assembly requirement in most cases, and further detection is not needed for the first antenna assembly and the second antenna assembly.
The antenna testing method can be used for conveniently and efficiently detecting the installation condition of the antenna in the assembling process of the antenna of the electronic equipment, and can realize automatic detection without other detection equipment except the electronic equipment, so that the detection efficiency is improved, and the detection cost is effectively reduced.
In an embodiment of the present application, after the generating the first test signal according to the trigger instruction, the method further includes the following steps:
and adjusting the frequency and/or the intensity of the first test signal according to the communication characteristics of the electronic equipment so as to enable the adjusted characteristic parameters of the first test signal to conform to a first signal range.
In particular, after the first test signal is generated, since the frequency and/or strength of the original first test signal cannot meet the standard of wireless transmission, especially cannot meet the standard required by the communication features of the electronic device, for example electronic devices require antennas capable of transmitting signals based on WIFI6 and 5G communication protocols, the original first test signal generated by the processing module cannot meet the standard, and therefore, the frequency and/or intensity of the first test signal needs to be adjusted, and the characteristic parameters, particularly the frequency and/or intensity, of the adjusted first test signal conform to the first signal range, and the first signal range is established based on the communication characteristics of the electronic device, such as the WIFI6 and 5G communication protocols, thereby enabling the adjusted first test signal to be wirelessly transmitted based on WIFI6 and the 5G communication protocol.
In one embodiment, the first antenna assembly includes a first antenna body and a first signal conditioning device, and the first signal conditioning device includes a first radio frequency transceiver and a first radio frequency front end. After the processing module generates the first test signal, the frequency of the first test signal is increased through the first radio frequency transceiver in the first antenna assembly, and the signal strength of the first test signal can be amplified through the first radio frequency front end in the first antenna assembly, so that the adjusted first test signal conforms to a first signal range, and then the adjusted first test signal is sent out through the first antenna body.
In an embodiment of the present application, the generating a first test signal according to a trigger instruction includes: sending, by a processing module in the electronic device, the first test signal via a first path;
correspondingly, the receiving, by a second antenna component of the electronic device, the first test signal to form a corresponding second test signal includes:
and adjusting the signal strength and/or signal frequency of the first test signal received by the second antenna assembly to form the second test signal, and receiving the adjusted second test signal through a second path by the processing module.
Specifically, the first path and the second path may be different paths, and the processing module sends the first test signal through the first path and receives the second test signal through the second path, so that the processing module can obtain the related technical information of the first test signal and the second test signal, and can further conveniently compare the first test signal with the second test signal. The method avoids using other equipment to participate in processing, saves system resources and can accurately obtain comparison results.
In addition, after the second antenna assembly receives the first test signal, in order to compensate for attenuation of the first test signal in the propagation process and facilitate comparison with the originally generated first test signal, the second antenna assembly needs to process the wirelessly received first test signal, a second radio frequency front end of the second antenna assembly may amplify signal strength of the first test signal according to the attenuation condition of the first test signal, a second radio frequency transceiver of the second antenna assembly further reduces the signal frequency of the first test signal to form a corresponding second test signal, and facilitates comparison with the originally generated first test signal (usually, the originally generated first test signal has a lower signal frequency), and the second test signal is received by the processing module through a second path.
In an embodiment of the present application, the comparing the first characteristic information of the first test signal with the second characteristic information of the second test signal to form a corresponding comparison result includes the following steps:
and comparing a first signal strength in the first characteristic information with a second signal strength in the second characteristic information based on first adjustment information for adjusting the first test signal and second adjustment information for adjusting the second test signal to form a corresponding comparison result, wherein the first signal strength is the signal strength of the first test signal when the first test signal is sent from the processing module, and the second signal strength is the signal strength of the second test signal when the second test signal is received by the processing module.
Specifically, after the processing module sends out the first test signal, the signal strength of the first test signal changes correspondingly through adjustment of the first antenna assembly and adjustment of the second antenna assembly. The first adjustment information records relevant information of the first antenna assembly for adjusting the first test signal, such as adjustment of signal strength and adjustment of frequency; similarly, the second adjustment information records the relevant adjustment information for adjusting the first test signal to form the second test signal, such as the adjustment of signal strength and the adjustment of frequency.
The first characteristic information includes information of characteristics of the first test signal when the processing module generates the first test signal, including a first signal strength of the first test signal when the processing module generates the first test signal. The second characteristic information includes characteristic information of the second test signal when the second test signal is formed, including a second signal strength of the second test signal. And comparing the first signal strength in the first characteristic information with the second signal strength in the second characteristic information, so that the accuracy of basic data during signal comparison can be ensured, and the interference to a comparison result caused by the adjustment of the first antenna assembly on the first test signal and the adjustment of the second antenna assembly on the second test signal can be avoided. So that the formed comparison result is extremely accurate.
Preferably, the determining whether the first antenna component and/or the second antenna component meet a preset assembly requirement if the comparison result meets a preset rule includes:
determining that the first antenna assembly and/or the second antenna assembly meets a preset assembly requirement if the difference between the first signal strength and the second signal strength is less than a preset threshold.
Referring to fig. 3, for development, the preset threshold may be preset according to the type of the electronic device and the communication standard, and a difference between the first signal strength and the second signal strength is smaller than the preset threshold, which indicates that the antenna assembly of the electronic device can normally transmit the communication signal and normally receive the communication signal, where an error is also in accordance with the communication requirement, and the first antenna assembly and/or the second antenna assembly is in accordance with the preset assembly requirement; however, if the difference between the first signal strength and the second signal strength is greater than the preset threshold, it indicates that the antenna assembly of the electronic device cannot normally transmit the communication signal or normally receive the communication signal, where the difference is large and does not meet the communication requirement, and the first antenna assembly and/or the second antenna assembly do not meet the preset assembly requirement, and the first antenna assembly and/or the second antenna assembly needs to be re-assembled and debugged. Of course, all antennas may be further detected specifically by performing reassembly and debugging on the first antenna assembly, reassembling and debugging on the second antenna assembly, or assembling and debugging on the first antenna assembly and the second antenna assembly. And because the situation that the antenna is assembled ineligibly in the electronic equipment is less, the reason for the abnormality can be found out quickly as long as the difference value between the first signal strength and the second signal strength is smaller than the preset threshold value.
In one embodiment of the present application, as shown in fig. 2, the method further comprises the steps of:
s6, setting a plurality of frequency test sections according to the communication characteristics of the electronic equipment;
s7, selecting a plurality of frequency measurement points on at least one frequency test section;
and S8, determining the frequency measuring point as the first test signal.
Particularly, in an actual use scene, a plurality of electronic devices can be simultaneously detected under a plurality of conditions, in order to avoid mutual interference, the scheme can be adopted, a plurality of frequency testing sections are arranged, a plurality of frequency testing points are selected on each frequency testing section, the frequency testing points can be randomly selected during detection of each electronic device, frequency hopping detection is realized, and the crosstalk phenomenon of test signals among the electronic devices is avoided.
Further, the communication characteristics of the electronic device characterize related characteristic information of a communication protocol or a communication standard on which the electronic device is based during communication, for example, communication is performed based on a WLAN communication protocol, and then a plurality of frequency test segments are set according to the communication characteristics of the electronic device, and a plurality of frequency test points are selected on each frequency test segment.
For example, for electronic equipment of a WLAN communication protocol, on a frequency test segment from 2.4GHz to 2.5GHz, a frequency point is selected as a frequency measurement point every 1MHz, so that the frequency points can be divided into n frequency measurement points, namely WLAN2.4_ f1, WLAN2.4_ f2, WLAN2.4_ f3 … …, WLAN2.4_ fn; similar divisions are also used for 5GHz to 5.8GHz frequency test segments and other frequency test segments.
Then randomly sequencing the tested frequency test sections (bands); for example, the electronic device has frequency test segments wlan2.4GHZ to 2.5GHZ, wlan5.0GHZ to 5.8GHZ, mobile communication Band1, mobile communication Band2, etc., and these frequency segments are randomly ordered to confirm the sequence of the frequency segments of the test. .
Then randomly extracting 10 frequency measurement points in each frequency measurement section to be measured, and randomly sequencing the 10 frequency points. Thereby forming a test sequence. For example, the test sequence may be that the WLAN5GHz to 5.8GHz frequency test segment is first tested, and then the WLAN2.4GHz to 2.5GHz frequency test segment is tested: 20 frequency measuring points such as WLAN5_ f14, WLAN5_ f39, WLAN5_ f3 … … WLAN2.4_ f9, WLAN2.4_ f59 and WLAN2.4_ f30 … … are arranged to form a sequence to be measured.
In one embodiment of the present application, the method further comprises: and transforming the frequency measurement points according to preset adjustment rules so as to avoid the interference phenomenon among a plurality of electronic equipment under the condition of testing the antennas of the plurality of electronic equipment.
In a specific embodiment, in the process of performing the antenna assembly test on each electronic device, the test software is used to randomly pick out the test sequence again, so as to ensure that the test sequence of each test of each electronic device is different, that is, the random conversion of the frequency measurement point is ensured. This minimizes interference during batch testing of the product.
In one embodiment of the present application, after determining the frequency measurement point as the first test signal, the method further comprises:
and synchronously controlling the first antenna component and the second antenna component, so that after the first antenna component emits the first test signal, the second antenna component can synchronously receive the first test signal at the same frequency as the first test signal.
Specifically, after the test sequence is confirmed, the modem in the processing module performs synchronous control on the first antenna assembly and the second antenna assembly, so as to ensure that the second antenna assembly is in a corresponding frequency point receiving state each time the first antenna assembly transmits the first test signal.
Furthermore, on the one hand, the transmission power of the first test signal is higher than the first power value, such as above 20dBm, and if it is lower than the first power value, it may be difficult to detect or the detection accuracy may be easily affected by the interference signal. On the other hand, the transmission signal of the first test signal is a single-tone signal, and a frequency measurement point which is not easily interfered in a space environment can be used.
It should be further noted that in an embodiment, N times of repeated verification of each frequency band of the antenna are achieved by performing tests on N frequency measurement points (N may be greater than 10) of each frequency measurement segment. Therefore, the test accuracy is improved, the test results of N times can be further processed, the maximum value and the minimum value in the comparison results are discarded at first, and the average calculation is carried out on the rest of the test results of N-2 times to ensure the accuracy. In another embodiment, the test process can also adopt a scheme of 2-3 times of cycle test operation to ensure the accuracy. For example, in the assembly quality verification process of the frequency band antenna in the wlan2.4GHZ to 2.5GHZ frequency test section, when the first verification does not meet the preset assembly requirement, the self-checking program automatically recycles the assembly quality verification operation of the frequency band antenna in the wlan2.4GHZ to 2.5GHZ frequency test section once, so as to reduce the erroneous judgment caused by external interference and the like.
An embodiment of the present application further provides an antenna testing apparatus for an electronic device, where the apparatus may be applied to an electronic device such as a mobile phone and a notebook computer, as shown in fig. 4 and combined with fig. 5, the apparatus includes:
the processing module is configured to generate a first test signal according to a trigger instruction;
the first antenna assembly is connected with the processing module and is configured to send out the first test signal after receiving the first test signal from the processing module;

the processing module is further configured to: comparing the first characteristic information of the first test signal with the second characteristic information of the second test signal to form a corresponding comparison result; and under the condition that the comparison result meets preset regulations, determining whether the first antenna assembly and/or the second antenna assembly meet preset assembly requirements.
Specifically, the trigger instruction may be generated after a preset condition is met, in an embodiment, with reference to fig. 3, after the electronic device enters the detection mode and starts to perform detection, the trigger instruction may be generated, for example, when the electronic device runs a self-test program and enters a factory mode, the trigger instruction is generated; in another embodiment, the user may actively issue the trigger command, such as operating the electronic device to generate the trigger command according to an actual test situation. The processing module generates a first test signal according to the trigger instruction. The first test signal is used for detecting the assembling condition of the antenna. The signal characteristic of the first test signal may be determined based on a device characteristic of the electronic device and a communication requirement of the antenna.
The first antenna assembly may include a first antenna body and a first signal adjusting device, where the first signal adjusting device may adjust a signal characteristic of the first test signal, and in an embodiment, the first signal adjusting device may adjust the first test signal according to a communication requirement when the electronic device is actually used, for example, adjust a signal frequency and a signal intensity, so that the adjusted first test signal is close to or equal to a signal sent by the first antenna assembly when the electronic device is actually used, and of course, adjustment information for adjusting the first test signal may be acquired by the electronic device, and particularly, may be acquired by a processing module in the electronic device, so as to be used later. The signal characteristic of the first test signal is adjusted and then emitted out through the first antenna body to radiate outwards.
The second antenna assembly is also one of the electronic devices, creating a situation where the electronic device itself transmits a signal and has itself received it. In this embodiment, the first test signal is received by the second antenna assembly in a wireless manner, and since the first test signal is lost during transmission, in this embodiment, the received first test signal may be adjusted, for example, the signal frequency and the signal strength may be adjusted, so as to form a corresponding second test signal, of course, the adjustment information for adjusting the first test signal may be acquired by the processing module for subsequent use, and the formed second test signal may be used to evaluate the first test signal.
The first characteristic information includes information of a characteristic of the first test signal when the first test signal is generated, and also includes information of a characteristic of the first test signal after the first test signal is adjusted. The first characteristic information represents signal characteristics of the first test signal, including information such as a signal frequency, a signal strength, and the like of the first test signal. Similarly, the second characteristic information includes characteristic information of the second test signal when the second test signal is formed, and information of characteristics of the second test signal after the second test signal is subjected to signal conditioning. The second characteristic information represents signal characteristics of the second test signal, including information such as signal frequency, signal strength, etc. of the second test signal. The processing module compares the first characteristic information with the second characteristic information, which may be comparing at least one characteristic point in the characteristic information, such as comparing signal strength.
The specific implementation of the comparison operation can be realized through the processing module, so that the processing module can send the first test signal, can receive the second test signal, and can also compare the first test signal with the second test signal, thereby being more convenient and accurate to obtain the comparison result. Preferably, the characteristics of the first test signal when the first test signal is generated may be compared with the characteristics of the received second test signal one by one to form a corresponding comparison result.
The preset regulation can be specifically set according to the production requirement of the electronic equipment and the requirements in practical application scenes such as the preset communication standard of the antenna, and if the comparison result meets the preset regulation, the first antenna assembly and the second antenna assembly can be determined to meet the preset assembly requirement without modifying the assembly operation of the first antenna assembly and the second antenna assembly; if the comparison result does not meet the preset regulation, the first antenna assembly and/or the second antenna assembly are considered not to meet the preset assembly requirement, and the first antenna assembly and the second antenna assembly can be further detected respectively, so that the antenna assembly is determined not to meet the preset assembly requirement. Of course, in the actual production process, the first antenna assembly and the second antenna assembly are in accordance with the preset assembly requirement in most cases, and further detection is not needed for the first antenna assembly and the second antenna assembly.
The embodiment of the application also provides electronic equipment, which comprises the antenna testing device, and the antenna testing device is used for detecting the antenna assembly of the electronic equipment.
