Referring to FIG. 2, an embodiment of the present invention provides

A method for improving WiFi performance comprises the following steps:

step S100, obtaining WiFi state parameters of a receiving end;

step S200, determining a comparison difference between the WiFi state parameter and a preset parameter;

step S300, generating a control signal according to the comparison difference;

step S400, the control signal is sent to the receiving end;

and S500, the receiving end changes the working main frequency according to the control signal, so that the working main frequency of the receiving end corresponds to the WiFi state parameter.

Specifically, in the prior art, when WiFi is used, the rate of the receiving end is often unsatisfactory under the condition that the transmitting end is good, which means that the receiving end cannot receive the useful signal of the transmitting end, and the performance is degraded and is often disconnected, and one of the reasons for the problem is that in the same environment, the wireless frequency band generated by the working dominant frequency of the receiving end system interferes with the frequency generated by WiFi communication, and the existence of the interference causes the problems of degraded WiFi performance, poor signal quality, increased error rate of received information, and the like.

In this embodiment, when the transmitting end communicates with the receiving end through WiFi, the transmitting end acquires WiFi state parameters of the receiving end in real time, where the WiFi state parameters are used to represent a current working state of a WiFi access of the receiving end, and the other receiving end working dominant frequency is used to represent a current working dominant frequency state of a receiving end master control system; determining a comparison difference between the WiFi state parameter and a preset parameter, and generating a control signal according to the comparison difference; sending the control signal to the receiving end; the receiving end changes the working dominant frequency according to the control signal; for example, when the WiFi channel of the receiving end is found to work lower than the preset rate, the transmitting end sends a control signal to the receiving end through the WiFi channel, so that the receiving end reduces the dominant frequency of the system work, thereby reducing the interference to the WiFi channel and achieving the effect of improving the performance of the WiFi receiving end.

Preferably, the step of generating the control signal according to the contrast difference includes the steps of:

when the WiFi state parameter is larger than the preset parameter, the contrast difference is a positive value;

generating a master frequency increasing control signal according to the comparison difference;

when the WiFi state parameter is smaller than the preset parameter, the contrast difference is a negative value;

and generating a main frequency reducing control signal according to the comparison difference.

Specifically, the comparison difference is used for judging the level of the current WiFi operating rate of the receiving end, and when the comparison difference is a positive value, the WiFi operating rate of the current receiving end is higher than a preset parameter value, so that the system operating efficiency of the receiving end can not be limited, and a master frequency control signal for improving the master frequency is generated and sent to the receiving end; on the contrary, when the contrast difference is a negative value, the WiFi working rate of the current receiving end is lower than the preset parameter value, and therefore the system working efficiency of the receiving end needs to be limited at this moment, so that a master frequency control signal is generated and improved to be sent to the receiving end, interference to a WiFi access is reduced by reducing the working master frequency of the receiving end system, and the effect of improving the performance of the WiFi receiving end is achieved.

Preferably, the step of changing the operating main frequency to bring about a change in WiFi performance includes the following steps:

the working main frequency of the receiving end can interfere with a WiFi access to influence the WiFi performance;

when the work dominant frequency of the receiving end is reduced, the frequency spectrum density of the stray signals can be reduced, the interference to a WiFi access is reduced, and the WiFi performance is improved.

Preferably, before the step of acquiring the status information of the receiving end, the method further includes the steps of:

the transmitting terminal and the receiving terminal are started and WiFi connection is established;

and the transmitting terminal loads a control module, and the control module is used for acquiring the state information of the receiving terminal.

Specifically, the control module is mainly used for detecting the state information of the receiving end in real time, generating a corresponding control signal according to the state information, and sending the control signal to the receiving end, wherein the effect of improving the WiFi performance is achieved by the receiving end according to the control signal.

The specific control process is as follows:

when the receiving end WiFi keeps working at a high-speed state, the transmitting end sends a master frequency increasing control signal to the receiving end, the receiving end gradually increases the system working master frequency according to the master frequency increasing control signal, the transmission efficiency of a communication interface is improved, meanwhile, the transmitting end reads the WiFi state of the receiving end in real time to keep high-speed state communication, when the fact that the WiFi starts to be switched from the high speed to the low speed is found, the transmitting end sends a master frequency reducing control signal to the receiving end, the receiving end gradually increases the system working master frequency according to the master frequency reducing control signal, therefore, interference on a WiFi access is reduced, the effect of improving the performance of the WiFi receiving end is achieved, when the WiFi of the receiving end keeps working at the high speed state, the control signal is readjusted to the receiving end, and the effect of improving the performance of the WiFi receiving end is achieved through circulation control.

Further, in the step of determining a comparison difference between the WiFi state parameter and a preset parameter, the WiFi state parameter is calculated according to the following formula:

WiFi state parameter (Kn × Noise + Kr × Rssi + Kb × BSS + Ks × SNR)/2;

wherein, RSSI represents the intensity of the received signal, Noise represents the intensity of Noise, SNR represents the signal-to-Noise ratio, BSS represents the number of surrounding signals, Kn, Kr, Kb and Ks are occupation ratio constants, and the sum of Kn, Kr, Kb and Ks is 1.

Specifically, in this embodiment, the WiFi state parameters include four parameters, i.e., RSSI represents received signal strength, Noise strength represents Noise strength, SNR represents signal-to-Noise ratio, and BSS represents the number of surrounding signals, and a current WiFi state parameter is obtained by performing corresponding weighting calculation on the four parameters, and is used to represent current WiFi communication quality, where Kn, Kr, Kb, and Ks are duty constants used to represent duty values of Noise, RSSI, BSS, and SNR, and a sum of Kn, Kr, Kb, and Ks is 1, and corresponding values are determined according to different environments; in this embodiment, Kn, Kr, Kb, and Ks respectively take values of 20%, 30%, and weight division is performed on different parameters, so that the actual application can be more flexible and accurate, for example, in an environment where the RSSI received signal strength fluctuates frequently and largely, the value of Kn can be appropriately increased to improve the sensitivity of response to the RSSI received signal strength, and the WiFi state can be better determined for different environments.

Further, determining a comparison difference between the WiFi state parameter and a preset parameter; the step of generating a control signal according to the comparison difference further comprises the following steps:

the preset parameters comprise a first preset value and a second preset value;

when the WiFi state parameter is larger than a first preset value, generating a control signal for reducing the system working dominant frequency; and when the WiFi state parameter is smaller than a second preset value, generating a control signal for increasing the working main frequency of the system.

Further, the method also comprises judgment values a and b, wherein the value is 1 when the Rssi is less than a, the value is 1.5 when the a is less than or equal to the Rssi and less than b, and the value is 2 when the Rssi is more than or equal to b.

Specifically, the judgment values a and b can be set according to different devices and use scenes, wherein a is-75 db, b is-30 db, namely, the value is 1 when the Rssi is < -75db, the value is 1.5 when the Rssi is not less than 75db, and the value is 2 when the Rssi is not less than-30 db

Further, the method also comprises judgment values c and d, wherein the value is 1 when Noise < c, the value is 1.5 when c is less than or equal to Noise < d, and the value is 2 when Noise is more than or equal to d.

Specifically, Noise is obtained through a radio frequency chip conduction index, the judgment values c and d can be set according to different devices and use scenes, in this embodiment, c is 10, d is 20, that is, when Noise is less than 10, the value is 1, when Noise is less than or equal to 10, the value is 1.5, and when Noise is greater than or equal to 20, the value is 2.

Further, the method also comprises judgment values e and f, wherein the value is 1 when the BSS is less than or equal to e, the value is 1.5 when the e is less than or equal to BSS and the value is 2 when the BSS is more than or equal to f.

Specifically, BSS represents the number of surrounding signals, the determination values e and f may be set according to different devices and use scenarios, where e is 10 and f is 20 in this embodiment, that is, a value 1 is taken when BSS <10, a value 1.5 is taken when BSS <20 is greater than or equal to 10, and a value 2 is taken when BSS is greater than or equal to 20.

Further, the method also comprises judgment values g and h, wherein the value is 1 when the SNR is less than g, the value is 1.5 when the SNR is less than or equal to g and is less than h, and the value is 2 when the SNR is more than or equal to h.

Specifically, the SNR is calculated by obtaining a useful power signal and a useless power through a wireless chip, and the specific calculation formula is as follows: SNR ═ wanted signal power/unwanted signal power; the judgment values g and h can be set according to different devices and use scenes, in this embodiment, g is 10, h is 20, that is, the value is 1 when SNR is less than 10, 1.5 when SNR is less than or equal to 10 and less than 30, and 2 when SNR is greater than or equal to 30.

Further, after the step of generating the reduced dominant frequency control signal according to the contrast difference, the method further comprises the following steps:

the receiving end reduces the working dominant frequency according to the dominant frequency reducing control signal, and the reduced working dominant frequency is smaller than the preset frequency; and the frequency doubling point of the reduced main frequency is not in the WIFI frequency range.

Specifically, in the embodiment, the preset frequency is 780MHz, if the system dominant frequency is F0, F0 is not greater than 780MHz, and when the WIFI frequency is 2.4GHz to 2.42GHz, F0 × n is not equal to 2.4GHz to 2.42GHz when the WIFI frequency is 5.1GHz to 5.8 GHz; f0 × n ≠ 5.1 GHz-5.8 GHz, wherein n represents a positive integer, and n × F0 represents a frequency point multiple of the main frequency.

More specifically, since the WiFi working rate needs to be increased after the system dominant frequency is reduced, the WiFi working rate needs to be reduced after the system dominant frequency is increased, and the variation amount of the WiFi working rate changes in a certain proportion of the current WiFi working rate, for example, when the current WiFi throughput performance is 2.4G, the variation amount of the WiFi working rate is about one gear, that is, about 20Mbps, when the current WiFi throughput performance is 5G, the variation amount of the WiFi working rate is about one gear, that is, 50-60Mbps, and the WiFi working rate is gradually increased or reduced according to the above-mentioned variation rule.
