A fourth embodiment of the present invention relates to an adaptive test method, which is applied to an adaptive test system including a switch array, a spectrometer, a signal generator, a network access device, and a client device. A specific flowchart of the adaptive testing method is shown in fig. 6.
Specifically, this step sets up the relevant parameter of frequency spectrograph, and the relevant parameter of frequency spectrograph includes: the method comprises the steps of selecting a channel power measurement option, a compensation parameter Cable LOSS (set according to line LOSS), a Ref parameter (set according to the Center Frequency of a channel), a Center Frequency parameter (Center Frequency) (set to be the same as the Center Frequency of the channel), a detection mode (generally set to Average detection), a scanning bandwidth (span) (generally set to be 0Hz), a Resolution Bandwidth (RBW) (generally set to be 8MHz), a Video Bandwidth (VBW) (generally set to be 50MHz) and a scanning period (Sweep time). In this embodiment, when initializing the spectrometer, the scan cycle of the spectrometer is set according to the test requirements of the device to be tested.
Specifically, the system, the bandwidth, and the channel of the network access device are set according to the test requirements of the device to be tested, that is, the system, the bandwidth, and the channel to be tested of the device to be tested are set. It should be noted that the system, bandwidth and channel supported by the network access device are not unique and are set by the device manufacturer. For example, the standard of the network access device is set as 11n, the bandwidth is set as 20M, and the channel is set as 1.
Specifically, the network access device may establish a network according to the set format, bandwidth, and channel, and then the client device establishes a connection with the network access device and performs data stream transmission on the channel set by the network access device. The data streaming may be a continuous uploading and downloading process.
In particular, the signal generator may send an interference signal of a certain frequency to the channel, which may affect the quality of the channel. For example, the interference signal may be an AWGN (white gaussian noise) interference signal, a CW (positive background wave) interference signal, or the like. It should be noted that the frequency of the interference signal is the same as the center frequency of the channel.
The type, number, and transmission timing of the interference signals are set according to the test requirements of the device under test.
Specifically, when detecting that the channel quality is poor or the channel is occupied, the device under test starts the adaptive function and skips the channel. When the device to be tested skips the channel, the transmission of the data stream on the channel is stopped, and the data stream on the channel can be interpreted by the spectrometer to stop transmission. It should be noted that the device under test is one of the client device and the network access device.
And step 106, the self-adaptive function of the equipment to be tested on the set system, bandwidth and channel is qualified.
Specifically, if the device under test starts the adaptive function to skip the channel when sending the interference signal to the channel, and determines that the data stream on the channel stops transmission through the spectrometer, it is determined that the adaptive function of the device under test is qualified.
In practice, the signal generator in step 104 sends the interference signal to the channel, and the signal generator may send multiple interference signals in sequence, where each interference signal lasts for a first preset time period, and two adjacent interference signals are sent at an interval of a second preset time period. For example, when the data stream transmission time read by the spectrometer is 10 seconds, the AWGN (white gaussian noise) interference signal is added, the first preset time is set to 40 seconds, and the second preset time is set to 20 seconds, and then, when the data stream transmission time read by the spectrometer is 70 seconds, CW (positive spike) interference is applied.
In the step 105, in the process of interpreting whether the data stream on the channel stops transmitting through the spectrum analyzer, in the process of inputting each interference signal into the channel, the spectrum analyzer interprets that the data stream on the channel stops transmitting, and then it is determined that the adaptive function of the device to be tested on the set system, bandwidth and channel is qualified. That is, under the condition that multiple interference signals are sequentially transmitted to the channel, the device to be tested can skip the channel and can determine that the self-adaptive function of the device to be tested is qualified, so that inaccuracy of the self-adaptive function determination result of the device to be tested due to the accidental test of a single interference signal is avoided.
It should be noted that the first preset time duration and the second preset time duration are both set according to the test requirement of the device to be tested.
In practice, the spectral image on the spectrometer may be saved after step 106, and the result may be recorded to facilitate the performance of subsequent tests and subsequent review.
The network access device 4 is taken as an example of a device to be tested (refer to fig. 1).
In this embodiment, a wireless router is selected as the network access device. The specific test process is as follows:
initializing a Frequency spectrograph, setting and selecting a channel power measurement option, setting a compensation parameter Cable Loss to be 1dBm, setting a Ref parameter to be 30dBm, setting a Center Frequency point parameter (Center Frequency) to be 2412MHz, setting a detection mode to be Average detection, setting a scanning bandwidth (span) to be 0Hz, setting a Resolution Bandwidth (RBW) to be 8MHz, setting a Video Bandwidth (VBW) to be 50MHz, and setting a scanning period (Sweep time) to be 130 seconds;
setting a mode of a wireless router as 11n, a bandwidth of 20M and a channel as 1, connecting a client device with a wireless network established by the wireless router, and starting data stream transmission on the channel 1;
when the transmission time of the data stream read by the spectrometer is 10 seconds, adding an AWGN (white Gaussian noise) interference signal of 2412MHz, setting the first preset time to be 40 seconds and the second preset time to be 20 seconds, and then applying CW (positive-going-wave) interference to 2412MHz when the transmission time of the data stream read by the spectrometer is 70 seconds;
when the interference signal is applied for 10 seconds, the data stream is interpreted by the spectrometer to stop transmission, while when the interference is applied for 70 seconds, the data stream is interpreted by the spectrometer to stop transmission again. Obtaining a conclusion that the equipment to be tested is qualified;
and storing the image on the frequency spectrograph, and recording the result.
In summary, when the wireless router works with the standard of 11n, the bandwidth of 20M and the channel of 1, and is interfered, the wireless router skips the channel 1, and the adaptive function is qualified.
It should be understood that this embodiment is a method example corresponding to the first embodiment, and may be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the first embodiment.
Compared with the prior art, the method has the advantages that under the set system, bandwidth and channel of the network access equipment, the client equipment and the network access equipment are connected, the signal generator sends interference signals to the channel, whether the data stream of the equipment to be tested on the channel stops or not is judged through the frequency spectrograph, if the data stream stops transmitting, the self-adaptive function of the equipment to be tested on the set system, bandwidth and channel is considered to be qualified, and the method is provided for judging whether the self-adaptive function of the equipment to be tested is qualified or not.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
A fifth embodiment of the present invention relates to an adaptive test method, and the present embodiment is an improvement of the fourth embodiment, and is mainly improved in that: a determination is added as to whether the spur is a data stream.
A specific flow of the adaptive testing method provided in this embodiment is shown in fig. 7.
Step 201 to step 205 correspond to substantially the same step as step 101 to step 105, and step 207 corresponds to substantially the same step as step 106, which are not described herein again; the difference is that step 206 and step 208 are added in the present embodiment, which is explained as follows:
and step 206, judging whether the clutter exists on the channel through the frequency spectrograph, and judging whether the clutter is the data stream. If yes, go to step 208; if not, go to step 207.
In particular, interpretation of data on a channel by a spectrometer does not stop transmission, but there are only some clutters, which may be data streams or due to environmental factors. Therefore, it is necessary to determine whether the clutter is a data stream, and if the clutter is not a data stream, it indicates that the device under test has skipped over the channel, then step 207 is performed, and the adaptive function of the device under test on the set system, bandwidth, and channel is considered to be qualified.
And step 208, the self-adaptive function of the equipment to be tested on the set system, bandwidth and channel is unqualified.
Specifically, if the clutter is judged to be a data stream, it is indicated that the device to be tested does not skip the channel, and the adaptive function of the device to be tested on the set system, bandwidth and channel is considered to be unqualified.
Compared with the first embodiment, the self-adaptive testing method provided by the embodiment judges whether clutter is data flow or not when the data flow on the channel is judged to be not stopped from being transmitted by the frequency spectrograph and the clutter exists on the channel, if so, the self-adaptive function of the device to be tested is considered to be unqualified, and otherwise, the self-adaptive function of the device to be tested is considered to be qualified. Thus, inaccuracy of test results due to environmental factors is avoided.
A sixth embodiment of the present invention relates to an adaptive test method, which is an improvement of the fourth embodiment, and mainly includes: before testing the self-adaptive function of the equipment to be tested, the hardware of the equipment to be tested is tested.
A specific flow of the adaptive testing method provided in this embodiment is shown in fig. 8.
Wherein, steps 301 to 303 are substantially the same as steps 101 to 103, steps 307 to 309 are substantially the same as steps 104 to 106, and are not repeated herein; the difference is that step 304, step 305 and step 306 are added in the present embodiment, which is specifically explained as follows:
it should be noted that in initializing the spectrometer in step 301, the scan cycle of the spectrometer is initialized to the first scan cycle.
Specifically, the channel occupation time of the data stream is calculated, that is, the transmission time of the data stream in one scanning period is calculated, and the transmission time of the data stream can be read from the spectrometer.
In practice, because the scanning period is not fixed, it is determined whether the channel occupation time of the data stream satisfies a predetermined condition, usually, whether the percentage of the channel occupation time of the data stream satisfies the predetermined condition is determined, the transmission time of the data stream is divided by the first scanning period, and then the first scanning period is multiplied by 100% to obtain the percentage of the channel occupation time of the data stream.
The preset condition may be a preset value, and when the percentage of the channel occupation time of the data stream is greater than the preset value, the channel occupation time of the data stream is considered to meet the preset condition. The present embodiment does not limit the preset conditions at all, and is set by a tester.
Specifically, when the channel occupation time of the data stream meets a preset condition, it is indicated that the hardware of the device to be tested does not have a problem. And then, disconnecting the client device from the network access device, clearing the spectrum image of the spectrometer, and setting the scanning period of the spectrometer as a second scanning period. The second scanning period is larger than the first scanning period.
In the present embodiment, the first scan cycle and the second scan cycle are not limited at all, and are set according to the test requirements of the device under test.
Specifically, the connection between the client device and the network access device is reestablished on a channel, the channel is the channel set before, data stream transmission is carried out on the channel again, and the test of the self-adaptive function of the device to be tested is continued.
The client device 5 is exemplified as a device under test (see fig. 2).
In this embodiment, a full network segment network card is selected as the client device. The specific test process is as follows:
initializing a Frequency spectrograph, setting and selecting a channel power measurement option, setting a compensation parameter Cable Loss to be 1dBm, setting a Ref parameter to be 30dBm, setting a Center Frequency point parameter (Center Frequency) to be 5180MHz, setting a detection mode to be Average detection, setting a scanning bandwidth (span) to be 0Hz, setting a Resolution Bandwidth (RBW) to be 8MHz, setting a Video Bandwidth (VBW) to be 50MHz, and setting a scanning period (Sweep time) to be 5 ms;
setting a mode of network access equipment as 11n, a bandwidth of 20M and a channel as 36, establishing connection between a network card of a whole network segment and the network access equipment, and starting data stream transmission on the channel 36;
reading the data stream transmission time T1 on the spectrometer, then T1 divided by 5ms times 100% yields a percentage of channel occupancy time greater than 30%;
disconnecting the network card of the whole network segment from the network access equipment, emptying images of the frequency spectrograph, and resetting the scanning period (Sweep time) of the frequency spectrograph to be 130 seconds;
re-establishing a connection between the network card of the whole network segment and the network access equipment, re-starting data stream transmission on the channel 36, and adding an AWGN (white Gaussian noise) interference signal of 5180MHz when the data stream transmission time read by the frequency spectrograph is 10 seconds;
