In order to more clearly explain the technical solutions in the embodiments of the present invention or the prior art, the drawings required for use in the embodiments or the prior art description will be briefly introduced below. Obviously, for those with ordinary knowledge in the relevant technical field, other drawings can be obtained based on these drawings without paying progressive labor.

It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention. In order to enable those with ordinary knowledge in the relevant technical field to better understand the scheme of this application, the technical scheme in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those with ordinary knowledge in the relevant technical field without making progressive labor should fall within the scope of protection of this application.

The present invention provides a WiFi testing method. Referring to FIG. 1, FIG. 1 is a schematic diagram of the process of the first embodiment of the WiFi testing method of the present invention. The WiFi testing method includes the following steps:

Step S10, if a test command is triggered, multiple test positions are determined, wherein different test positions have different relative positions with the test antenna 300.

Test instructions are used to instruct the execution of test operations; test instructions can be triggered manually by testers, or by detecting the position of the target device and automatically triggered when the target device reaches the specified position.

The test position refers to the position of the target device when performing the WiFi test operation. The relative position between the test position and the test antenna 300 includes the straight-line distance, vertical distance, angle, etc.; it can be understood that at different test positions, the signal transmission state between the target device and the test antenna 300 is different. For example, when the distance between the target device and the test antenna 300 is far, the path loss of the signal is higher. The specific test position can be selected based on actual needs.

Step S20, control the target device corresponding to the test instruction to perform WiFi test operations at each test location.

This embodiment performs WiFi test operations at multiple test locations, which can simulate different application scenarios, thereby testing the WiFi function of the target device in different application scenarios, and performing a more comprehensive WiFi test operation on the target device.

The target device is a device with WiFi function, including but not limited to smart phones and wearable devices. In this embodiment and subsequent embodiments, the target device is a smart watch as an example for explanation. Other types of target devices can be implemented in the same way and will not be elaborated.

Specific WiFi test operation items can be set based on test needs, and the corresponding subroutines of all executable test items can be stored in advance. Before performing tests on the target device, staff can select the items to be tested, and generate a default test program based on the subroutines corresponding to the selected test items to implement WiFi test operations.

It should be noted that the WiFi test operations corresponding to different test locations can be the same or different.

Step S30, obtain the test results of the WiFi test operation, and generate calibration parameters based on the test results.

The test results can reflect the test status of the target device; when the test results show that the WiFi function of the target device deviates from the expectation, the calibration parameters can be determined based on the aforementioned deviation, so that the target device can calibrate the WiFi function to be consistent with the expectation based on the calibration parameters.

Specifically, when determining the calibration parameters, the calibration parameters can be determined based on the relative position relationship between the target device and the test antenna 300, and the relevant signals detected in the WiFi test operation are compared with the preset standard signals, and then the calibration parameters are stored in the WiFi chip memory of the target device, so that the target device calls the calibration parameters to achieve calibration when using the WiFi function.

At the same time, the tester can also process the target device according to the test results, such as the internal WiFi antenna of the smart watch and the terminal of the smart watch main control board are not pressed tightly, so that the smart watch cannot receive WiFi signals or transmit WiFi signals. When the test result shows that the target device cannot receive or send WiFi signals, the connection status of the WiFi antenna and the terminal of the smart watch main control board can be checked.

The present invention also provides a WIFI test device applied to the above WIFI test method, see Figure 2, the WIFI test device includes a control module 100, a WiFi analyzer 200, a test antenna 300, and a transport device 400. The control module 100 is connected to the WiFi analyzer 200 and the transport device 400 respectively, the WiFi analyzer 200 is connected to the test antenna 300, and the transport device 400 is connected to the target device. Among them, the control module 100 is used to perform the following steps: when the test command is triggered, multiple test positions are determined.

Control the movement of the transport device 400 so that the transport device 400 carries the target device corresponding to the test instruction and moves to each test location.

The transport device 400 communicates with the target device, and the WiFi analyzer 200 communicates with the test antenna 300 to perform WiFi test operations.

Obtain the test result of the WiFi test operation, and determine whether the target device is qualified according to the test result.

The control module 100 serves as the control center of the WiFi test device and realizes the control and detection of the working status of each module and communicates with each module.

Specifically, the specific connection method between different modules can be selected based on actual needs, such as the control module 100 and the WiFi analyzer 200 are connected via a network communication via the TCP/IP (Transmission Control Protocol/Internet Protocol) communication protocol, and the control module 100 and the transport equipment 400 are connected via a USB communication.

The transport device 400 is electrically connected to the target device, and the transport device 400 provides power to the target device and establishes a communication connection. After the target device is placed on the transport device 400, the transport device 400 reads the device information of the target device, such as the WiFi chip hardware version information, the driver software version information, and the device serial number, and sends the device information to the control module 100. The control module 100 determines the corresponding WiFi test operation according to the device information.

This embodiment can detect the performance of the target device in different scenarios by performing a WiFi test operation on the target device at a different relative position from the test antenna 300, and then generate calibration parameters based on the actual test results, which can correct the deviation of the WiFi function of the target device and ensure the accuracy of the WiFi function of the target device in actual applications.

In the second embodiment of the WiFi test method of the present invention proposed based on the first embodiment of the present invention, referring to FIG3, the WiFi test device further includes a Z-axis track 511 and an X-axis track 513, the X-axis track 513 is arranged on a horizontal plane, the X-axis track 513 and the Z-axis track 511 are located in the same vertical plane, and the Z-axis track 511 is perpendicular to the X-axis track 513. The test antenna 300 is movably arranged on the Z-axis track 511, and the transport equipment 400 is movably arranged on the X-axis track 513.

The antenna module is mounted on the antenna bracket 520 through a buckle, and the antenna bracket 520 is mounted on the Z-axis track 511 through a fastening screw. The distance between the test antenna 300 and the transport equipment 400 in the vertical direction can be adjusted by adjusting the fastening screw. At the same time, a height scale 512 is provided on the Z-axis track 511 to indicate the distance between the antenna and the transport equipment 400 in the vertical direction.

The test antenna 300 includes a 2.4G antenna 310 and a 5G antenna 320, and the test position includes a second test position S2. The projection of the second test position S2 on the line connecting the 2.4G antenna 310 and the 5G antenna 320 is located at the midpoint of the line connecting the 2.4G antenna 310 and the 5G antenna 320.

The 2.4G antenna 310 is provided with a 2.4G antenna scale 531, and the precise distance of the 2.4G antenna 310 in the Y-axis direction can be adjusted by adjusting the knob on the 2.4G antenna scale 531; the 5G antenna 320 is provided with a 5G antenna scale 532, and the precise distance of the 5G antenna 320 in the Y-axis direction can be adjusted by adjusting the knob on the 5G antenna scale 532.

The 2.4G antenna 310 is connected to the WiFi analyzer 200 via the 2.4G antenna 310 coaxial cable, and the 5G antenna 320 is connected to the WiFi analyzer 200 via the 5G antenna 320 coaxial cable.

An electromagnetic pneumatic valve 600 connected to the transport equipment 400 is provided on the X-axis track 513. The electromagnetic pneumatic valve 600 is electrically connected to the control module 100. The electromagnetic pneumatic valve 600 is connected to the horizontal support of the transport equipment 400. The control module 100 controls the electromagnetic pneumatic valve 600 to realize the movement of the transport equipment 400 in the X-axis direction. An X-axis horizontal scale is provided on the X-axis to indicate the position of the transport equipment 400 in the X-axis direction.

In this embodiment, the distances between the transport equipment 400 and the 2.4G antenna 310 and the 5G antenna 320 in the X, Y, and Z axes can be precisely adjusted and indicated.

The test positions include a first test position S1 and a second test position S2, and step S10 includes the steps:

Step S11, obtaining the first distance H1 between the first test position S1 and the test antenna 300; wherein the first test position S1 and the test antenna 300 are aligned at the center of the horizontal plane projection, and the first distance H1 is the first multiple of the WiFi signal wavelength.

Step S12, obtaining the second distance H2 corresponding to the second test position S2; wherein the second distance H2 is the second multiple of the WiFi signal wavelength, and the first multiple is different from the second multiple.

Step S13, determine the second test position S2 according to the first distance H1 and the second distance H2.

The specific values of the first distance H1 and the second distance H2 can be set based on actual needs. Based on general test requirements, the first distance H1 can be set to 3λ~5λ, where λ is the wavelength of the WiFi signal.

Since the first distance H1 is the distance between the first test position S1 and the test antenna 300, and the second test position S2 is located directly below the test antenna 300, the first distance H1 is the shortest distance between the test position and the test antenna 300, and the straight line indicated by the first distance H1 is perpendicular to the horizontal plane. When the second distance H2 based on the second multiple is determined, the straight line indicated by the second distance H2, the straight line indicated by the first distance H1, and the horizontal plane form a right triangle. At this time, the distance of the second test position S2 relative to the first test position S1 can be determined by the Pisces theorem, thereby realizing the determination of the first test position S1 and the second test position S2; in addition, the angle of the second test position S2 relative to the test antenna 300 can be further calculated.

Further, the WiFi test operation includes the steps:

Step S21, sending a first test signal to the target device, so that the target device sends a first radio frequency signal corresponding to the first test signal to the WiFi analyzer 200.

Step S22, obtain the first detection signal collected by the WiFi analyzer 200 based on the first radio frequency signal, and test the transmission performance of the target device according to the first detection signal.

The test objects of WiFi function mainly include the signal transmission performance and reception performance. When testing the transmission performance, the target device needs to actively send out a signal, that is, the first radio frequency signal, and detect the first radio frequency signal.

It is understandable that there are many types of performance parameters related to transmission performance, and they also need to be tested based on different WiFi communication protocols. Therefore, the first test signal may include multiple sub-signals, or indicate multiple sub-signals. If the first test signal includes multiple sub-signals, the control module 100 sends different sub-signals in sequence, so that the target device sends the corresponding first RF signal in sequence; if the first test signal indicates multiple sub-signals, the control module 100 sends the first test signal to the target device, and the target device sends the first RF signal corresponding to the sub-signal in sequence according to the first test signal. The same applies to the subsequent second test signal, which will not be repeated.

Specifically, different signal debugging modes can be set for the first RF signal based on the channel transmission power, transmission frequency and the corresponding WiFi communication protocol; non-signaling lists can also be set based on different parameter changes, such as the corresponding RF signals based on different settings of transmission power, carrier center frequency offset, bandwidth and other parameters, so as to send the first RF signals corresponding to the sub-signals of different first test signals in different signal adjustment modes, and WiFi communication protocols such as 802.11a/b/g/n/ac/ax.

The control module 100 controls the target device to enter the non-signaling mode. The target device sends the first RF signal according to the non-signaling list based on the first test signal. The WiFi analysis receives two first detection signals corresponding to the first RF signal through the 2.4G antenna 310 and the 5G antenna 320. The WiFi analyzer 200 has a built-in WiFi baseband chip and a signal adjustment circuit to measure the transmission power measurement parameters, frequency measurement parameters and modulation quality test parameters corresponding to the first detection signal at fixed bandwidths of 20MHz, 40MHz, 80MHz and 160MHz. Among them, the transmit power measurement parameters include transmit power and transmit spectrum mask; the frequency measurement parameters include transmit center frequency error and orthogonal frequency division multiplexing (OFDM) symbol clock frequency error; the modulation quality test parameters include error vector error magnitude (EVM) and I-Q constellation diagram.

The WiFi analyzer 200 synchronizes the above test parameters to the control module 100, and the control module 100 obtains the relevant parameters of the first RF signal synchronized between the target device and the WiFi analyzer 200 and the test parameters detected by the WiFi analyzer 200 at fixed bandwidths of 2.4G and 5G frequency points, and determines whether the transmission power, the attenuation value of the transmission spectrum at the center frequency offset, and the maximum deviation of the center frequency exceed the preset deviation value, such as ±20ppm specified by international standards, or a lower deviation value required by the enterprise. When the preset deviation value is exceeded, the transmission performance of the target device is considered unqualified. If it does not exceed the preset deviation value, the transmission performance of the target device is considered qualified.

The WiFi test device may also include a display module, which is used to display relevant information of the test operation, such as the control module 100 sending the vertical distance, angle, straight line distance, test results, current test process, etc. corresponding to the test position to the display module for display.

It should be noted that as a device for performing test operations on the target device, the receiving performance and sending performance of the WiFi analyzer 200 itself should be standard; however, in actual applications, due to the production accuracy of the WiFi analyzer 200 or errors caused by operation, the receiving performance and sending performance of the WiFi analyzer 200 deviate. Therefore, before performing WiFi test operations on the target device, the WiFi signal power, signal frequency, and signal vector error EVM output and received by the WiFi analyzer 200 can be calibrated through a calibrated WiFi vector signal analyzer, and the calibration compensation values such as path loss can be written into the WiFi analyzer 200 or the control module 100 to ensure the receiving performance and sending performance accuracy of the WiFi analyzer 200.

Step S23, sending a second test signal to the WiFi analyzer 200, so that the WiFi analyzer 200 sends a second radio frequency signal corresponding to the second test signal to the target device through the test antenna 300.

Step S24, obtaining a second detection signal collected by the target device based on the second radio frequency signal, and testing the signal sensitivity of the target device according to the second detection signal.

When testing the receiving performance, it is necessary to provide the target device with a signal (i.e., the second RF signal), and then detect the second detection signal obtained after the target device receives the second RF signal.

The second radio frequency signal includes multiple first sub-signals and multiple second sub-signals. The transmission power of the multiple first sub-signals is the same and the frequency offsets of the multiple first sub-signals are different, and the multiple frequency offsets of the multiple second sub-signals are the same and the transmission power of the multiple second sub-signals is different.

Specifically, different signal debugging modes can be set for the second RF signal based on the channel transmission power, transmission frequency and the corresponding WiFi communication protocol. It is also possible to set a non-signaling list based on different parameter changes, such as the corresponding RF signal based on different settings of parameters such as transmission power, carrier center frequency offset, and bandwidth, so as to send the second RF signal corresponding to the sub-signal of different second test signals in different signal modulation modes, and the WiFi communication protocol is such as 802.11a/b/g/n/ac/ax.

The control module 100 controls the target device to enter the non-signaling mode, and controls the WiFi analyzer 200 to output the 2.4G 2.412GHz, 2.442GHz, 2.472GHz frequency points, and the 5G 5.180GHz, 5.260GHz, 5.320GHz frequency points according to the non-signaling list through the 2.4G antenna 310 and the 5G antenna 320. The target device receives the second RF signal from the WiFi analyzer 200, and the WiFi antenna inside the target device receives the second detection signal based on the second RF signal, and performs IQ demodulation on the second detection signal. Since the phase difference between the I and Q signals is 90 degrees, the orthogonality of the I and Q signals can be used to complete the power estimation. The relevant formulas for I and Q signals are as follows: I ( t ) = A ( t ) × cos ( ω ( t ) + r ( t ))

Among them, I(t) and Q(t) represent the WiFi time domain signal, A(t) represents the time domain amplitude function of the WiFi baseband signal, ω (t) represents the angular frequency of the baseband signal, and r(t) represents the phase of the baseband. By calculating the power value of each point of the discrete time domain signal, that is, the sum of the squares of the I-path signal and the Q-path signal, the power estimation of the signal can be reflected.

The target device sends the receiving sensitivity, error vector magnitude EVM, center frequency, working channel, power and other important performance parameters of the second detection signal corresponding to the second RF signal of different frequency points and different powers to the control module 100. The control module 100 calculates the working channel, transmission power, transmission spectrum, transmission center frequency, error vector magnitude EVM and receiver sensitivity of the target device according to the relative position relationship between the target device and the test antenna 300 and the second RF signal. When calculating the receiving sensitivity, step S24 includes:

Step S241, obtain the sensitivity standard parameter corresponding to the second test signal.

Step S242, determine the WiFi failure value based on the sensitivity standard parameter and the second detection signal.

Step S243, determine the signal sensitivity of the target device according to the WiFi failure value.

The sensitivity standard parameter is used to indicate the characteristics of the second detection signal obtained by the target device based on the second RF signal when the target device has perfect reception performance; the WiFi failure value can be determined by comparing the sensitivity standard parameter and the second detection signal to achieve the evaluation of signal sensitivity.

This embodiment can accurately test the WiFi function of the target device.
