S103: and removing interference on the wireless signals according to the descrambling factors of the working frequency bands.
The interference eliminating method for wireless signal transmission of the intelligent router system is applied to electronic equipment, and the electronic equipment can be a computer, a server and other equipment.
In the process of transmitting the wireless signal by the intelligent router system, the electronic equipment monitors the amplitude information of the wireless signal. The electronic equipment stores a preset normal amplitude range corresponding to the wireless signal, and detects whether the wireless signal has interference or not according to the monitored amplitude information of the wireless signal and the preset normal amplitude range. Optionally, if the monitored amplitude information of the wireless signal is within a preset normal amplitude range, determining that the wireless signal is not interfered, otherwise, determining that the wireless signal is interfered. If the wireless signal has no interference, the process is ended.
And if the wireless signal is determined to have interference, acquiring the idle channel quantity information of each working frequency band of the intelligent router system. Optionally, each working frequency band of the intelligent router system is 2.4G and 5G, and the idle channel number information of the 2.4G working frequency band and the idle channel number information of the 5G working frequency band are respectively determined. And determining the descrambling factors of the working frequency bands according to the idle channel quantity information of the working frequency bands. Optionally, the descrambling factor of the 2.4G working frequency band is according to the idle channel number information of the 2.4G working frequency band, and the descrambling factor of the 5G working frequency band is according to the idle channel number information of the 5G working frequency band. And finally, performing interference removal processing on the wireless signals according to the interference removal factors of the working frequency bands.
Optionally, when determining the number of idle channels according to each working frequency band, determining the descrambling factor of each working frequency band, taking the ratio of 1 to the number of idle channels as the descrambling factor. For example, if the number of idle channels in the 2.4G operating band is 4, the descrambling factor of the 2.4G operating band is 1/4=0.25. And if the number of idle channels of the 5G working frequency band is 2, the descrambling factor of the 5G working frequency band is 1/2=0.5.
In the method, amplitude information of wireless signals transmitted by the intelligent router system is monitored, and normal amplitude ranges of the wireless signals are preset. According to the amplitude information of the wireless signals and a preset normal amplitude range, whether the wireless signals have interference is judged, so that the automatic detection of wireless signal transmission interference aiming at the intelligent router system is realized. If the wireless signal is determined to have interference, acquiring the idle channel number information of each working frequency band of the intelligent router system, determining a descrambling factor of each working frequency band according to the idle channel number information of each working frequency band, and then performing interference removal processing on the wireless signal based on the descrambling factor. Thus, interference elimination of wireless signals aiming at the intelligent router system is realized.
In order to perform interference detection on a wireless signal more accurately, in the present application, performing interference detection on the wireless signal includes:
acquiring high-amplitude information and low-amplitude information in the amplitude information;
and if the high-amplitude information is larger than the maximum amplitude information in the normal amplitude range or the low-amplitude information is smaller than the minimum amplitude information in the normal amplitude range, determining that the wireless signal has interference.
The method comprises the steps of monitoring amplitude information of wireless signals transmitted by an intelligent router system, and specifically acquiring high-amplitude information and low-amplitude information in the amplitude information. If the high-amplitude information and the low-amplitude information are both in the preset normal amplitude range, the wireless signal is determined to have no interference. If either one of the high amplitude information and the low amplitude information is not within a preset normal amplitude range, the interference of the wireless signal is determined. That is, if the high amplitude information is greater than the maximum amplitude information in the normal amplitude range or the low amplitude information is less than the minimum amplitude information in the normal amplitude range, it is determined that the wireless signal is interfered.
For example, the predetermined normal amplitude range is [10dB, 50dB ], and the high amplitude information is 80dB and the low amplitude information is 50dB in the amplitude information of the wireless signal, so that it is found that the high amplitude information is not in the normal amplitude range, and it is determined that the wireless signal has interference. If the high amplitude information is 50dB and the low amplitude information is 20 dB in the amplitude information of the radio signal, it is determined that the radio signal has no interference.
In order to further perform interference detection on a wireless signal more accurately, in the present application, performing interference detection on the wireless signal includes:
acquiring a first duration of high-amplitude information and a second duration of low-amplitude information in the amplitude information;
and if the first duration is not in the preset high-amplitude duration or the second duration is not in the preset low-amplitude duration, determining that the wireless signal has interference.
The electronic device stores a preset normal amplitude range, a preset high amplitude duration and a preset low amplitude duration. After monitoring amplitude information of a wireless signal transmitted by the intelligent router system, high-amplitude information and low-amplitude information in the amplitude information are acquired, and a first duration of the high-amplitude information and a second duration of the low-amplitude information are acquired.
If the high amplitude information is larger than the maximum amplitude information in the normal amplitude range or the low amplitude information is smaller than the minimum amplitude information in the normal amplitude range, the interference of the wireless signal is directly determined. If the high-amplitude information and the low-amplitude information are both within the normal amplitude range, it is further determined whether the first duration of the high-amplitude information is within a predetermined high-amplitude duration and whether the second duration of the low-amplitude information is within a predetermined low-amplitude duration. If the high-amplitude information and the low-amplitude information are both in the normal amplitude range, and the first duration of the high-amplitude information is in the preset high-amplitude duration and the second duration of the low-amplitude information is in the preset low-amplitude duration, determining that the wireless signal is not interfered, otherwise determining that the wireless signal is interfered.
For example, the preset high amplitude duration is 10 milliseconds and the preset low amplitude duration is 20 milliseconds. If the first duration of the high-amplitude information is 8 milliseconds, the first duration of the high-amplitude information is determined to be within a preset high-amplitude duration. If the second duration of the low amplitude information is 25 milliseconds, it is determined that the second duration of the low amplitude information is not within the preset low amplitude duration.
In order to further perform interference detection on a wireless signal more accurately, in the present application, performing interference detection on the wireless signal includes:
if the high-amplitude information is greater than the maximum amplitude information in the normal amplitude range or the low-amplitude information is less than the minimum amplitude information in the normal amplitude range, determining an interference amplitude ratio of the wireless signal according to the high-amplitude information, the maximum amplitude information, the low-amplitude information and the minimum amplitude information;
and if the interference amplitude ratio is larger than a preset first interference amplitude ratio threshold value, determining that the wireless signal has interference.
If the high-amplitude information is greater than the maximum amplitude information in the normal amplitude range or the low-amplitude information is less than the minimum amplitude information in the normal amplitude range, the interference amplitude ratio of the wireless signal can be determined according to the high-amplitude information, the maximum amplitude information, the low-amplitude information and the minimum amplitude information before the wireless signal is determined to have interference. If the interference amplitude ratio is larger than a preset first interference amplitude ratio threshold value, determining that the wireless signal has interference, otherwise, still determining that the wireless signal has no interference. The preset first disturbance amplitude ratio threshold is, for example, 20%, 30%, or the like.
And determining an interference amplitude ratio of the wireless signal according to the high-amplitude information, the maximum-amplitude information, the low-amplitude information and the minimum-amplitude information. Optionally, the high amplitude information in the wireless signal is G1, the low amplitude information is G1, the maximum amplitude information in the normal amplitude range is ZG, and the minimum amplitude information is ZD, and the interference amplitude ratio of the wireless signal is (G1-D1)/(ZG-ZD).
If the wireless signal is determined to have interference, acquiring the idle channel number information of each working frequency band of the intelligent router system comprises the following steps:
and if the interference amplitude ratio is larger than a preset first interference amplitude ratio threshold and smaller than a preset second interference amplitude ratio threshold, acquiring the idle channel quantity information of each working frequency band of the intelligent router system.
The preset second disturbance amplitude ratio threshold is, for example, 75%, 80%, or the like. If the interference amplitude ratio is larger than a preset first interference amplitude ratio threshold and smaller than a preset second interference amplitude ratio threshold, the wireless signal is indicated to have interference, the interference degree is low, and interference removal can be achieved according to each working frequency band in the intelligent router system. Therefore, the idle channel quantity information of each working frequency band of the intelligent router system is obtained, and wireless signal interference elimination is carried out by depending on each working frequency band of the intelligent router system.
If the interference amplitude ratio is not less than a preset second interference amplitude ratio threshold, the method further comprises:
and performing interference removal processing on the wireless signal through an embedded communication module in the intelligent router system.
And if the interference amplitude ratio is not smaller than a preset second interference amplitude ratio threshold value, the wireless signal is indicated to have interference, and the interference degree is higher. The interference removal process can be performed on the wireless signal according to an embedded communication module in the intelligent router system. The embedded communication module is, for example, a bluetooth module.
On the other hand, if the interference amplitude ratio is greater than the preset first interference amplitude ratio threshold and less than the preset second interference amplitude ratio threshold, interference elimination is achieved according to each working frequency band inside the intelligent router system. After interference elimination is achieved according to each working frequency band in the intelligent router system, interference amplitude ratio after interference elimination of the wireless signals is determined again according to interference elimination factors of each working frequency band. Optionally, the interference amplitude ratio to be removed in each working frequency band is first determined, and the product of the interference amplitude ratio to be removed and the interference factor to be removed is used as the interference amplitude ratio after interference removal. If interference still exists in the wireless signals after interference removal is detected according to the interference amplitude ratio after interference removal, interference removal processing is carried out on the wireless signals through an embedded communication module in the intelligent router system.
Specifically, the removing interference processing for the wireless signal through the embedded communication module in the intelligent router system includes:
acquiring the number information of idle channels of an embedded communication module in the intelligent router system, and determining a descrambling factor of the embedded communication module according to the number information of idle channels of the embedded communication module; and removing interference to the wireless signal according to the descrambling factor of the embedded communication module.
For example, the number of idle channels of the embedded communication module is 4, and the descrambling factor of the embedded communication module is determined to be 1/4=0.25. And removing interference to the wireless signal according to the descrambling factor of the embedded communication module.
It should be noted that, the interference removal processing for the wireless signal according to the interference removal factor may be that the data amount of the wireless signal is divided according to the interference removal factor, and the divided wireless signal is equally divided into idle channels for transmission, so as to implement interference removal.
