Example two

Referring to fig. 7, an automatic optimization method for an antenna direction of a WIFI wireless router includes the following steps:

step S1: the router is turned on and the antenna module 1 is triggered.

Specifically, the present embodiment divides the position of the antenna 12 from 0 to 360 degrees into n step values in advance according to the position of the stepping motor, each step value corresponding to one antenna direction. After the router is turned on, the antenna module 1 is automatically triggered, and the process proceeds to step S2.

Step S2: and sequentially scanning the signal intensity of the wireless equipment connected to the router when the step values are 1 to n, recording the signal intensity corresponding to each step value, and calculating to obtain the average value, the minimum value and the dispersion of the signal intensity.

In this embodiment, starting from the 1 st step value, the signal strengths of the wireless devices connected to the router are scanned and all the signal strengths are recorded. An average value and a minimum value are calculated from the recorded signal intensities, and a dispersion of the first set of signal intensities is calculated therefrom.

After the data processing for the 1 st step value is complete, the antenna 12 rotates into the 2 nd step value, continues to scan the signal strengths of the wireless devices connected to the router, and records all signal strengths. The mean and minimum values are calculated from the recorded signal intensities and the dispersion of the signal intensities of the second group is calculated therefrom.

And so on, until the antenna 12 rotates one turn, completing the scanning of all n step values, each step value having corresponding signal strength, average value and dispersion, that is, obtaining n sets of data of signal strength, average value and dispersion, and going to step S3.

Step S3: and (3) counting and calculating the data of the signal intensity, the minimum value, the average value and the dispersion obtained in the step (2) to obtain the optimal direction of the antenna 12.

In this embodiment, first, a first step value sorting data set is obtained according to the ascending order of the average value of the signal strength, and then a second step value sorting data set is obtained according to the ascending order of the discrete value of the signal strength.

And defaults to select the data of the m before the ranking in the two data groups for comparison, and obtains the number of the stepping values of the m before the ranking in the two data groups. Specifically, the number of coincidences occurs for the step value of m before the ranking in the two data sets. In this embodiment, the data of the top five is selected, that is, m is equal to five.

If only one step value is ranked m times in the two data sets, the direction corresponding to the step value is taken as the optimal direction.

If more than one step value is ranked m before the two data sets, the step values are selected, the minimum value of the signal intensity corresponding to each step value is compared, the step value with the maximum signal intensity minimum value is selected, and the direction corresponding to the step value is taken as the optimal direction.

And if no stepping value is ranked m before the two data sets, namely the stepping values m before the two data sets are not overlapped, increasing the ranking by one bit, comparing the stepping values m +1 before the ranking, repeating the steps, and the like until the corresponding stepping value is selected, and taking the direction corresponding to the stepping value as the optimal direction.

Step S4: according to the optimal direction of the antenna 12 obtained in step 3, the control unit 22 sends a control signal to the rotating unit 11, and the rotating unit 11 automatically rotates the antenna 12 to the optimal direction.

EXAMPLE III

The automatic optimization method for the WIFI wireless router antenna 12 can be triggered in multiple modes.

The first is automatic start-up triggering, that is, the automatic start-up triggering is automatically performed once after each start-up. The second embodiment adopts automatic triggering after the computer is started.

The second is a timed auto-trigger, which triggers the antenna 12 to adjust and re-optimize the antenna direction.

Specifically, after step 4 in the second embodiment, the process proceeds to step S5.

Step S5: and according to the time interval preset by the user, the step S2 to the step S4 are carried out again at intervals. For example, the user may re-optimize the antenna direction once every 5 minutes, as desired.

The third is connection auto-triggering, i.e. whenever the number of users connected to the router increases or decreases, the auto-triggering antenna 12 adjusts to re-optimize the coverage.

Specifically, after step S4 in embodiment two, the process proceeds to step S6.

Step S6: the number of users connected to the router is detected in real time, and when the number of users connected to the router increases or decreases, step S2 to step S4 are repeated. In this embodiment, the number of users connected to the computer at the time of starting up is used as a reference value, or the user can set the reference value by himself. And if the number of the users changes relative to the reference value and the coverage is optimized again, judging whether the number of the users increases or decreases by taking the changed number of the users as the reference value. And by analogy, the reference value is continuously adjusted.

The fourth is the combination of connection auto-triggering and timed-triggering modes, i.e. the timed-triggered antenna 12 adjusts to re-optimize the antenna direction without a change in the number of users.

Specifically, after step S5 in the present embodiment, the process proceeds to step S6.

In summary, the present invention provides a WIFI wireless router and an antenna direction automatic optimization method thereof, where the router includes an antenna module including a rotation unit (a stepping motor and a rotation shaft), and can automatically adjust an antenna coverage range, and can reasonably adjust an antenna direction according to a difference in user distribution and a difference in environment, so as to optimize signal strength of a plurality of access users as much as possible, and optimize using experience of the plurality of users.
