In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

Fig. 1 is a schematic flowchart of a method for adaptively adjusting wireless signal strength according to an embodiment of the present invention. It should be noted that the method for adaptively adjusting wireless signal strength provided in the embodiment of the present invention is applied to a wireless network, where the wireless network includes a control device and a plurality of wireless access hotspot devices. Specifically, as shown in fig. 1, the method for adaptively adjusting the wireless signal strength may include the following steps:

step S11: after the power-on is started, the plurality of wireless access hotspot devices all send account information of the wireless access hotspot devices to the control device.

In the embodiment of the present invention, in a specific implementation, a plurality of wireless access hotspot devices are respectively distributed in a plurality of rooms, and each room has at least one; in addition, the control device is implemented by a terminal device with data processing capability, such as a computer, and it is understood that the control device may also be implemented by a chip or a processor with data programmable logic processing function, such as an embedded processor, a field programmable gate array processor, and the like.

In addition, in the embodiment of the present invention, the self account information sent by the wireless access hotspot device to the control device includes, but is not limited to, identification information of the self account, that is, identity information, password information, and the like.

In this embodiment of the present invention, as shown in step S11, the account information of the wireless hotspot device includes, but is not limited to, own identification information and password information, and after the control device receives the own account information sent by the wireless hotspot device, the control device establishes a mapping table according to the identification information and the password information of each wireless access hotspot device, so as to complete registration of each wireless access hotspot device. After the control device registers each wireless access hotspot device, the control device sends a signal intensity acquisition instruction and a distance acquisition instruction to each wireless access hotspot device, wherein the distance acquisition instruction refers to an instruction for acquiring the physical distance between every two wireless access hotspot devices.

Further, as a preferred embodiment of the present invention, the method for adaptively adjusting wireless signal strength according to the present invention further includes:

when the control device receives the wireless signal intensity of the control device relative to other wireless access hotspot devices acquired by the wireless access hotspot device and the distances between the control device and other wireless access hotspot devices acquired by the wireless access hotspot device, judging whether all the wireless access hotspot devices acquire the wireless signal intensity of the control device relative to other wireless access hotspot devices and whether all the wireless access hotspot devices acquire the distances between the control device and other wireless access hotspot devices;

if the two judgment results are yes, the control equipment acquires wireless signal intensity adjusting information of each wireless access hotspot device according to the fed back relative wireless signal intensity and distance; and if one of the two judgments is negative, the control equipment sends an information acquisition instruction to the wireless access hotspot equipment again.

In the embodiment of the present invention, when the control device receives the wireless signal strength of the wireless access hotspot device relative to other wireless access hotspots and the distance between the control device and other wireless access hotspot devices, the control device traverses the information collected by each wireless access hotspot device to determine whether each wireless access hotspot device collects the information. If one wireless access hotspot device does not acquire the wireless signal strength of the wireless access hotspot device relative to other wireless access hotspot devices or the distance between the wireless access hotspot device and other wireless access hotspot devices, the control device sends an information acquisition instruction to the wireless access hotspot device again, so that the wireless access hotspot device acquires corresponding information again according to the information acquisition instruction, and each wireless access hotspot device can acquire the wireless signal strength of the wireless access hotspot device relative to other wireless access hotspot devices and the distance between the wireless access hotspot device and other wireless access hotspot devices.

In the embodiment of the invention, when each wireless access hotspot device acquires the wireless signal intensity of the wireless access hotspot device relative to other wireless access hotspot devices according to the signal intensity acquisition instruction sent by the control device and acquires the distance between the wireless access hotspot device and other wireless access hotspot devices according to the distance acquisition instruction sent by the control device, the acquired relative wireless signal intensity and distance are sent to the control device through the communication module in the wireless access hotspot device so as to feed back the control device.

It should be noted that, in the embodiment of the present invention, the communication module in each wireless access hotspot device may be a wired communication module, and may also be a wireless communication module. When the communication module in the wireless access hotspot device is a wired communication module, the communication module can be realized by adopting a wired network; when the communication module in the wireless access hotspot device is a wireless communication module, the communication module can be realized by adopting wireless communication modes such as bluetooth and the like.

Step S14: and the control equipment acquires the wireless signal intensity adjusting information of each wireless access hotspot equipment according to the fed back relative wireless signal intensity and distance, and sends the wireless signal intensity adjusting information to the corresponding wireless access hotspot equipment.

In the embodiment of the present invention, after the control device receives the relative wireless signal strength and distance fed back by each wireless access hotspot device, the control device obtains the wireless signal strength adjustment information of each wireless access hotspot device according to the fed-back wireless signal strength and distance, and then sends the wireless signal strength adjustment information to the corresponding wireless access hotspot device through the communication module therein.

Specifically, as a preferred embodiment of the present invention, the step S14 of acquiring, by the control device according to the fed back relative wireless signal strength and distance, the wireless signal strength adjustment information of each wireless access hotspot device specifically includes:

the control equipment determines a minimum adjusting unit according to the distance between each wireless access hotspot device and other wireless access hotspot devices, and performs descending order arrangement on a plurality of wireless access hotspot devices included in the minimum adjusting unit according to the relative wireless signal strength;

the control equipment takes the last wireless access hotspot equipment in descending order as a reference point, and acquires wireless signal strength adjusting information of a plurality of wireless access hotspot equipment in the minimum adjusting unit according to a target signal threshold;

the control equipment eliminates part of wireless access hotspot equipment in a plurality of wireless access hotspot equipment included in the minimum adjusting unit; the part of the wireless access hotspot devices are wireless access hotspot devices sequentially counted from the beginning wireless access hotspot devices in the descending order to a preset target number;

and the control equipment returns to the step of determining the minimum adjusting unit according to the distance between each wireless access hotspot device and other wireless access hotspot devices which are left after the elimination and continues to execute until the wireless signal strength adjusting information of each wireless access hotspot device in the wireless network is obtained.

Further, as a preferred embodiment of the present invention, the determining, by the control device, a minimum adjusting unit according to a distance between each wireless access hotspot device and another wireless access hotspot device, and performing descending order arrangement on the plurality of wireless access hotspot devices included in the minimum adjusting unit according to the relative wireless signal strength specifically includes:

the control device takes three nearest wireless access hotspot devices as the minimum adjusting unit according to the distance between each wireless access hotspot device and other wireless access hotspot devices, and performs descending order arrangement on the three wireless access hotspot devices in the minimum adjusting unit according to the sum of the relative wireless signal strengths of each wireless access hotspot device in the minimum adjusting unit relative to other wireless access hotspot devices in the minimum adjusting unit.

The following describes in detail the process of the control device acquiring the wireless signal strength adjustment information of the wireless access hotspot device by taking a specific implementation scenario as an example:

it is assumed that the wireless network applied by the method for adaptively adjusting the wireless signal strength provided by the present invention includes A, C and D three wireless access hotspot devices, and each wireless access hotspot device is distributed in one room. When the relative wireless signal strength of each wireless access hotspot device relative to other wireless access hotspot devices fed back to the control device is A (AC: -40 dBm; AD: -60dBm), C (AC: -40 dBm; CD: -50dBm) and D (AD: -60 dBm; CD: -50dBm), respectively, and the distance between each wireless access hotspot device and other wireless access hotspot devices fed back to the control device is Lac: 3 m, Lad: 2.5 meters and Lcd: and 3.5 m, the control equipment performs wireless signal strength adjustment information acquisition operation according to the information fed back by the wireless access hotspot equipment.

Specifically, the control device first uses the three closest wireless access hotspot devices as the minimum adjusting unit according to the distance between each wireless access hotspot device and other wireless access hotspot devices, that is, the control device determines a minimum triangle according to the distance between each wireless access hotspot device and other wireless access hotspot devices, where the minimum triangle is a triangle with the minimum circumference formed by the three wireless access hotspot devices. It should be noted that, since three wireless access hotspot devices A, C and D are taken as examples in this embodiment, the minimum adjusting unit in this embodiment is a minimum triangle formed by the wireless access hotspot device A, C and D, and when a wireless network includes more than three wireless access hotspot devices, the minimum adjusting unit is determined by using the minimum triangle, which is not described herein again.

When the control device determines the minimum adjusting unit, the control device respectively obtains the sum of the relative wireless signal strengths of the wireless access hotspot device A in the minimum adjusting unit relative to the wireless access hotspot devices C and D in the minimum adjusting unit, such as-100 dBm, the sum of the relative wireless signal strengths of the wireless access hotspot device C in the minimum adjusting unit relative to the wireless access hotspot devices A and D in the minimum adjusting unit, such as-90 dBm, and the sum of the relative wireless signal strengths of the wireless access hotspot device D in the minimum adjusting unit relative to the wireless access hotspot devices C and A in the minimum adjusting unit, such as-110 dBm, and performs descending order arrangement on the three wireless access hotspot devices A, C and D in the minimum adjusting unit according to the obtained sums, wherein the sequence after arrangement is C (AC: -40 dBm; CD: -50dBm), A (AC: -40 dBm; AD: -60dBm), D (AD: -60 dBm; CD: -50 dBm).

After the control device performs descending order arrangement on the wireless access hotspot devices A, C and D in the minimum adjusting unit, because the wireless access hotspot device D is arranged at the end, the wireless access hotspot device D is taken as a reference point, and wireless signal strength adjusting information of the wireless access hotspot device A, C and D in the minimum adjusting unit is obtained according to a target signal threshold.

Specifically, the target signal threshold is that the wireless signal strength of each wireless access hotspot device is-75 dBm relative to other wireless access hotspot devices, and after the control device performs descending order arrangement on the wireless access hotspot devices A, C and D in the minimum adjusting unit, since the signal strength difference between the wireless access hotspot device C and the other two wireless access hotspot devices is the largest, the control device obtains the wireless signal strength adjusting information of the wireless access hotspot device C of-25 dBm according to the wireless signal strength of the wireless access hotspot device C relative to the other wireless access hotspot devices a and D and the target signal threshold of-75 dBm. After the control device acquires the wireless signal strength adjustment information of the wireless access hotspot device C in the minimum adjustment unit, the control device sequentially acquires the wireless signal strength adjustment information of the wireless access hotspot devices A and D in the same manner as the wireless access hotspot device C, wherein the wireless signal strength adjustment information of the wireless access hotspot devices A and D is-15 dBm and 0dBm respectively.

It should be noted that, in the embodiment of the present invention, the process of obtaining the wireless signal strength adjustment information of the wireless access hotspot devices a and D is the same as that of the wireless access hotspot device C, and the wireless signal strength adjustment information of the wireless access hotspot device C may be specifically referred to, and is not described herein again; in addition, in the embodiment of the present invention, the relative wireless signal strength threshold of each wireless access hotspot device with respect to other wireless access hotspot devices is not absolutely-75 dBm, which may have a certain difference from-75 dBm, and the difference may not exceed 10dBm in principle.

After the control device obtains the wireless signal strength adjustment information of the multiple wireless access hotspot devices in the minimum adjustment unit, one or more wireless access hotspot devices in the minimum adjustment unit may be removed, that is, the number of targets may be one, or two or three, in this embodiment, the wireless access hotspot devices a and C are mainly removed.

When the control device removes the wireless access hotspot devices a and C in the minimum adjusting unit, the wireless access hotspot device in the minimum adjusting unit only has D, but the wireless network of the example of the present invention only includes three wireless access hotspot devices A, C and D, and the wireless signal strength adjustment information of the wireless access hotspot device D has been acquired, the control device may end the wireless signal strength adjustment information acquisition process of the wireless access hotspot device.

It can be understood that, when the wireless access hotspot devices included in the wireless network of the present invention are more than A, C and D, the control device will re-determine the minimum adjusting unit according to the wireless access hotspot devices after the wireless access hotspot devices a and C are removed, and further obtain the wireless signal strength adjusting information of the wireless access hotspot devices in the newly determined minimum adjusting unit until the wireless signal strength adjusting information of each wireless access hotspot device; the process of acquiring the wireless signal strength adjustment information of the wireless access hotspot device in the minimum determined minimum adjusting unit is the same as the process of acquiring the wireless signal strength adjustment information of the wireless access hotspot device in the first minimum adjusting unit, so that reference may be made to the detailed description of the process of acquiring the wireless signal strength adjustment information of the wireless access hotspot device in the first minimum adjusting unit, which is not repeated here.

Step S15: and each wireless access hotspot device adjusts the signal intensity of the wireless access hotspot device according to the corresponding wireless signal intensity adjusting information.

In the embodiment of the present invention, after each wireless access hotspot device receives its own wireless signal strength adjustment information sent by the control device, its own signal strength is adjusted according to the corresponding wireless signal strength adjustment information, so that the terminal device of the user can smoothly switch among the wireless access hotspot devices. Specifically, for example, when the wireless signal strength adjustment information of the wireless access hotspot device a is respectively-15 dBm, the wireless access hotspot device a reduces its signal strength by-15 dBm according to the wireless signal strength adjustment information; and when the wireless signal strength adjusting information of the wireless access hotspot equipment C is-25 dBm respectively, the wireless access hotspot equipment C reduces the signal strength thereof by-25 dBm according to the wireless signal strength adjusting information.

In this embodiment, the distance and the relative wireless signal strength between the multiple wireless access hotspot devices are acquired by the control device, and the wireless signal strength adjustment information of each wireless access hotspot device is acquired according to the acquired relative wireless signal strength and distance and then is sent to the corresponding wireless access hotspot device, so that each wireless access hotspot device adjusts the signal strength of itself according to the corresponding wireless signal strength adjustment information, and further, the problem of untimely network switching caused by unreasonable position deployment of the wireless access hotspot device can be effectively avoided, manual operation is not needed, the efficiency is high, and the cost is low.

In the embodiment of the present invention, a specific implementation process of step S22 is the same as the implementation process of step S12 shown in fig. 1, and reference may be specifically made to the related description of step S12, which is not described herein again.

In the embodiment of the present invention, a specific implementation process of step S24 is the same as the implementation process of step S14 shown in fig. 1, and reference may be specifically made to the related description of step S14, which is not described herein again.

Further, as a preferred embodiment of the present invention, the method for adaptively adjusting wireless signal strength further includes:

when receiving the wireless signal intensity of the wireless access hotspot device relative to other wireless access hotspot devices acquired by the wireless access hotspot device and the distances between the wireless access hotspot device and other wireless access hotspot devices acquired by the wireless access hotspot device, judging whether all the wireless access hotspot devices acquire the wireless signal intensity of the wireless access hotspot device relative to other wireless access hotspot devices and whether all the wireless access hotspot devices acquire the distances between the wireless access hotspot devices and other wireless access hotspot devices;
