Based on the above hardware structure, an embodiment of the router channel setting method of the present invention is provided.
Referring to fig. 2, a first embodiment of the present invention provides a router setting method, where the router setting method includes:
step S10, acquiring initialization setting information of the router to be set and information of the routing hot spot within a preset range, wherein the initialization setting information comprises default initialization setting information or initialization setting information set by a user;
the embodiment is applied to the field of wireless communication, such as channel setting of a wireless router. In this embodiment, the router to be set refers to a router currently started by a user or a router to be updated which reaches a preset update channel setting time. When a user starts the router, the router firstly sets information according to initialization, including initialized frequency band information or bandwidth information. The initialization information may be default factory information set by a factory owner, or may be initialization setting information modified by a user. For example, the initialization setting information may be a 2.4GHz band and an operating bandwidth of 20M. The router acquires initialization setting information when being started, and initializes setting options such as a working frequency band and a working bandwidth according to the initialization information. The router searches for a WiFi router hotspot in the space while acquiring the initialization setting information of the router, and acquires working channels, working bandwidths and signal strength information of other working routers in the searched space. In this embodiment, the router to be set may obtain information such as channel setting, signal strength, and the like of the surrounding routing hotspot by obtaining the signal frame. The preset range of this embodiment refers to a range covered by a scanning function of the router to be set, the routing hotspot of this embodiment refers to a router which is in an operating state in the preset range around the router to be set and can be scanned and identified by the router to be set, and step S10 implemented in this embodiment may be executed when the router is started, or may be executed at certain time intervals during the operation of the router. Since the channel or power of the surrounding routing hot spot may change with time, the user may preset the time for updating the channel, for example, 1 hour, and in the operation process of the router, the information such as the signal strength and channel setting of the current surrounding routing hot spot is obtained every other hour, and the channel is adjusted and reset according to the information of the current routing hot spot. The router channel setting method of the embodiment can be finished by self-adaption of the router to be set, and can also be finished by combining terminals such as a smart phone, namely after the router to be set acquires self initialization setting information and surrounding hotspot information, the router to be set determines the optimal working channel, and channel adjustment is finished in a self-adaption mode; the router to be set can also send the acquired initialization setting information and the acquired ambient hotspot information to the terminal, the terminal determines the optimal working channel of the router, and sends a channel setting instruction to the router to be set.
Step S20, determining the optimal channel value of the router to be set according to the initialization information and the routing hotspot information;
based on the above steps, in this embodiment, it is determined whether the working frequency band of the corresponding routing hotspot is the same as the initialization working frequency band of the router to be set, a routing hotspot signal strength threshold, for example, -65dBm, may be preset in advance according to the router working principle and the actual performance, after the router acquires the signal strength information of a plurality of surrounding routing hotspots, it is first determined whether the routing strength is-65 dBm greater, when the signal strengths of the surrounding routing hotspots acquired by the router with the setting are all smaller than-65 dBm, the surrounding routing hotspots may not generate interference to the router to be set or the generated interference may be ignored or not calculated, and the router to be set may use any preset channel as an optimal working channel, for example, channel 1. In this embodiment, after the routing information of the surrounding routing hotspots is obtained, it may be further determined whether the working frequency band of the corresponding routing hotspot is the same as the initialization working frequency band of the router to be set, and the interference of the routing hotspot of the working frequency band and the router to be set, which are different from the working frequency band of the router to be set, may be negligible, so that the routing hotspots of different working frequency bands are not taken as an influencing factor when considering the optimal channel. For example, the initial working frequency band to be set is 2.4GHz, the working frequency band of a certain route of the surrounding route hotspots is 5GHz, when the router determines the optimal channel, the route hotspots with the working frequency band of 5GHz can be abandoned, and the remaining route hotspots with the working frequency band of 2.4GHz are taken as the analysis objects. When the number of the surrounding routing hotspots is small, the router to be set can set the working channel to a different working channel with small mutual interference with the surrounding routing hotspots. For example, when the operating band of the surrounding route is channel 1, the router to be set sets the operating band to channel 6. For the condition that routing hot spots are more, based on the working principle of the router and the mutual interference principle, the isolation measurement of the interference between the relevant channel and other channels is calculated quantitatively, and the channel with the largest anti-interference measurement is used as the optimal working channel of the router. Based on the principle, the router to be set can also calculate the anti-interference measurement of the relevant channel by using a preset formula according to the initialization setting information and the information of the surrounding route hotspots, and the channel value with the maximum anti-interference measurement is taken as the optimal channel value. In this embodiment, the router to be set determines a channel value corresponding to the optimal channel by using the initialization information and the relevant information of the surrounding routing hot spots.
And step S30, setting the working channel value of the router to be set as the optimal channel value.
In this embodiment, initialization setting information of a router to be set and information of a routing hotspot within a preset range are acquired; determining an optimal channel value of the router to be set according to the initialization information and the routing hotspot information; and setting the working channel value of the router to be set as the optimal channel value. By the mode, the optimal working channel value is determined according to the initialization setting information and the related setting information of the surrounding routing hot spots, and the setting is carried out according to the optimal working channel value, so that the problem that the working channels of the routers are mutually interfered when the routers work due to the fact that the working channels of the routers are close to the surrounding routing hot spots by manual setting of user randomness or the routers are close to the surrounding routing hot spots according to default setting is solved, and the routing transmission efficiency is improved.
Further, referring to fig. 3, fig. 3 is a schematic flow chart of a router setting method according to a second embodiment of the present invention.
Based on the foregoing embodiment, in this embodiment, the initialization setting information at least includes initialization operating frequency band information, the routing hotspot information includes operating frequency band information and signal strength value information of a routing hotspot, and step S20 includes:
step S40, determining a routing hot spot consistent with the working frequency band of the router to be set according to the working frequency band information of the routing hot spot information and the initialized working frequency band information, and obtaining a first routing hot spot set;
step S50, judging whether a routing hotspot with a signal strength value larger than a signal strength threshold exists in the first routing hotspot set according to the signal strength value information;
step S60, when there is no routing hotspot whose signal strength value is greater than the signal strength threshold in the first routing hotspot set, determining that the optimal channel value is a preset channel value.
In this embodiment, the operating frequency band is a frequency range in which the router operates, and one operating frequency band may include a plurality of channels, for example, 13 channels in a 2.4GHz frequency band. In an actual use scenario of the router, two routers in different working frequency bands do not interfere with each other due to a large distance between the two frequency bands, and therefore, when considering the interference factor of the router, a routing hotspot with different working frequency bands may not be taken as a consideration object. Based on the above embodiment, in this embodiment, after the to-be-set router acquires the information of the surrounding routing hotspots, the routing hotspots that are inconsistent with the self-initialized working frequency band are discarded first, and the routing hotspots that are consistent with the self-initialized working frequency band are reserved as set elements in the first routing hotspot set. The signal strength of the surrounding routing hot spots of the router to be set at the position of the router to be set is also related to the distance between the two, the structural characteristics of the space building between the two and other factors. When the signal intensity generated by the routing hot spot at the position where the to-be-set route is located is smaller than a certain threshold value, although the signal intensity can be acquired by the to-be-set router, the interference actually generated to the data transmission function of the router can be ignored, and the to-be-set router can set a channel according to a preset channel. In this embodiment, after the signal strength information of the surrounding routing hotspots is obtained, it is determined whether the signal strength value of each surrounding routing hotspot is greater than the signal strength threshold, and when the signal strength values of all the surrounding routing hotspots are less than the signal strength threshold, the router is set by taking the preset channel value as the optimal channel value. The preset value in this embodiment may be set by a router manufacturer, or a user may modify the preset value in the router setting. In this embodiment, there may also be a routing hotspot with a signal strength value greater than the signal strength threshold value in the surrounding routing hotspots, and when there is a routing hotspot with a signal strength value greater than the signal strength threshold value, an optimal channel value with less interference with the routing hotspot with a signal strength value greater than the signal strength threshold value is determined according to the router working principle and the interference principle, and the channel setting parameter is set to the optimal channel value.
In this embodiment, irrelevant routing hotspots are removed through the operating frequency band parameters, and when the signal intensity of the surrounding routing hotspots is small, the settings are performed according to the preset channel value, so that the determination of the optimal channel value and the channel setting are quickly completed.
Further, referring to fig. 4, fig. 4 is a schematic flow chart of a router channel setting method according to a third embodiment of the present invention.
Based on the foregoing embodiment, in this embodiment, the routing hotspot information further includes working channel value information of the routing hotspot, and after step S50, the method further includes:
step S70, when a routing hot spot with a signal strength value larger than the signal strength threshold exists in the first routing hot spot set, obtaining a second routing hot spot set according to the routing hot spot with the signal strength value larger than the signal strength threshold;
step S80, determining the working channel values of the routing hotspots in the second routing hotspot set and the number of routing hotspots corresponding to each working channel value;
step S90, judging whether there is a working channel value with the number of routing hot spots larger than a first preset number;
step S100, when the number of the routing hot spots is larger than the first preset number of working channel values, taking the routing hot spot with the maximum signal intensity value as a representative routing hot spot corresponding to the working channel values, and determining a third routing hot spot set according to the representative routing hot spot and the routing hot spot corresponding to the working channel values of which the number of the routing hot spots is the first preset number;
step S110, determining an optimal channel value of the router to be set according to the working channel value and the signal strength value of each routing hotspot in the third routing hotspot set.
The router may scan for one or more routing hotspots with signal strength values greater than a signal strength threshold, i.e., routing hotspots with signal strength values greater than-65 dBm. According to the above principle, in order to further improve the processing efficiency, based on the above embodiment, the routing hotspots in the first routing hotspot set are further screened, the routing hotspots in the first routing hotspot set whose signal strength is smaller than the threshold are discarded, and all the routing hotspots form a new set, that is, the second routing hotspot set, according to the fact that the signal strength value in the first routing hotspot set is greater than the threshold. After the scanned signal intensity value is larger than a routing hot spot of-65 dBm, the anti-interference metric value of each channel can be calculated according to the presetting, and the optimal channel value is determined according to the isolation metric value. And when the number of the routing hot spots in the second routing hot spot set is more or the number of the channels occupied by the routing hot spots is more, keeping the hot spot with the maximum signal intensity value for the router hot spot with the same channel, and discarding the hot spot. In this embodiment, the channel occupied by the route hotspot of the second route hotspot set is determined first, and then the number of route hotspots occupying the channel in the second route hotspot set is determined. Whether the working channel value with the routing hot spot number larger than the first preset number exists is judged, the preset number is a preset number and can be set to 1, for example, whether the channel value is set to be the working channel value by more than one routing hot spot is judged. When the working channel value with the number of the routing hot spots larger than 1 exists, the routing hot spot with the maximum signal intensity value is determined from the routing hot spots corresponding to the working channel value, the routing hot spot is used as a representative routing hot spot of the working channel value, and other routing hot spots of the channel value are discarded.

Further, referring to fig. 5, fig. 5 is a schematic flow chart of a fourth embodiment of the router channel setting method of the present invention.
Based on the foregoing embodiment, in this embodiment, the routing hotspot information further includes working bandwidth information of the routing hotspot, and step S110 includes:
step S120, calculating the interference resistance of each channel value corresponding to the initialized working frequency band information according to the working bandwidth information, the signal intensity value, the working channel value and a preset formula of the routing hotspot in the third routing hotspot set to obtain a corresponding interference resistance value;
step S130, determining a channel value corresponding to the maximum interference rejection value, and taking the corresponding channel value as an optimal channel value.
The working bandwidth information of the routing hotspot in this embodiment refers to a frequency band bandwidth of the router, which is a transmission frequency width of the router. The 2.4GHz working frequency band comprises two working bandwidth values of 20MHz and 40MHz, the 20MHz corresponds to a 65M bandwidth, the penetrability is good, the transmission distance is long, and the transmission distance is about 100 meters; 40MHz corresponds to a 150M bandwidth, poor penetration and transmission distances of about 50 meters or so. In this embodiment, when the router to be set acquires the routing information of the surrounding routing hotspot in step S10, the router to be set acquires the working frequency band information, the working bandwidth information, and the signal strength information of the routing hotspot. After the third routing hotspot set is determined, calculating the interference resistance of each channel value corresponding to the initialization working frequency band information according to the working bandwidth information, the signal intensity value, the working channel value and a preset formula of the routing hotspot in the third routing hotspot set, and obtaining the corresponding interference resistance value. The interference resistance value of this embodiment is an interference isolation metric value generated by each working channel in the working frequency band relative to existing routing hotspots around the router to be set, and the larger the interference resistance value is, the smaller the interference from the surrounding routing hotspots when the router to be set sets the working channel value as the channel value is. The degree of interference resistance corresponding to the channel value is related to factors such as the working bandwidth, the signal strength and the working channel of the surrounding routing hot spot. Because the surrounding routing hotspots exist near the router to be set at the same time, when the anti-interference value of a certain channel in the working frequency band is calculated, the anti-interference value of each routing hotspot of the channel needs to be summed, the summed value is used as the anti-interference value of the channel, and the channel value corresponding to the maximum anti-interference value is obtained as the optimal channel value.
In this embodiment, the interference resistance metric of the relevant channel is calculated quantitatively, the optimal channel value is determined according to the interference resistance metric, and a more accurate channel value is obtained by a quantitative calculation method.

When the working bandwidth is 40M, the set A is (2, 4, 8), and the number of the routing hot spots corresponding to each channel value in the set A is 1, for the channel 1, the anti-interference value is 1
F1＝W1(1)*1.2*|1-2|+W1(2)*1.2*|1-4|+W1(3)*1.2*|1-8|
In the same way, the interference rejection values F of the other channel values 3, 5, 6, 7, 9, 10, 11, 12, 13 of the set C can be calculated3、F5、F6And the like. After the calculation is finished, from F1、F3、F5、F6And determining the maximum anti-interference value in all the anti-interference values, and taking the maximum channel value x corresponding to the anti-interference value as the optimal channel value.
