Description

Technical Field

[0001] The present invention relates to the technical field of router adjustment, and in particular to an adjustment method and system for a router antenna. Background Art

[0002] The router antenna is a key hardware component for its wireless signal transmission. It is used to transmit and receive wireless signals and is a key component for wireless network communication. The router antenna is not only related to the coverage of the wireless signal, but also directly affects the quality of the network. These antennas allow data to be transmitted between different devices by converting electrical signals into radio waves, or vice versa, converting received radio waves back into electrical signals.

[0003] Adjusting the router antenna is an important measure to optimize the wireless network coverage and signal strength. The omnidirectional antenna radiates the wireless signal evenly in the horizontal direction. When the router antenna is placed at 90 degrees perpendicular to the ground, the wireless signal has the widest coverage. By adjusting the direction and position of the antenna, the signal coverage effect can be maximized.

[0004] In the prior art, the direction and position of the router antenna are usually adjusted when it is placed, and the signal radiation range of the router's omnidirectional antenna is fixed. Therefore, for a home router, the signal radiation range of the router is fixed within the user's activity range, and there are areas with weak signals and areas with strong signals. However, users are always active, so when using the signal within the user's activity range, the signal often becomes unstable as the position moves. Summary of the invention

[0010] Step S3: when there is a mobile device within the activity range, the position coordinates of the mobile device are acquired in real time to obtain the speed of the mobile device. When the time when the speed of the mobile device is equal to 0 exceeds a preset time threshold, the position coordinates of the mobile device at this time are recorded as the mobile device point.

[0011] Step S4: Set a flow threshold Tt, and obtain the flow consumption Tc at the mobile device point.

[0032] Beneficial effects of the present invention:

[0033] In the prior art, the direction and position of the router antenna are usually adjusted when it is placed, and the signal radiation range of the router's omnidirectional antenna is fixed. Therefore, for a home router, the signal radiation range of the router is fixed within the user's activity range, and there are areas with weak signals and areas with strong signals. However, users are always active, so when using the signal within the user's activity range, the signal is often unstable as the position moves;

BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Figure 1 The invention discloses a structural diagram of an adjustment method and system for a router antenna. DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 As shown, the present invention is a method for adjusting a router antenna, comprising the following steps:

[0039] Step S1: obtaining the activity range of the user, obtaining all network devices connected to the router antenna within the activity range; dividing the network devices into fixed devices and mobile devices;

[0040] The fixed devices include televisions and computers, and the mobile devices include mobile phones and tablets;

[0041] It is understandable that fixed devices usually do not change their positions, such as TVs and computers. By determining the positions of these devices, a relatively stable signal coverage model can be established. In contrast, mobile devices such as mobile phones and tablets often change their positions and need to dynamically adjust signal coverage. Classification helps router antennas adopt different signal optimization strategies according to different types of devices;

[0042] Step S2: obtaining the position coordinates of the fixed device, recorded as the fixed device point, obtaining the plane coplanar with the fixed device points, recorded as the initial plane; adjusting the angle of the router antenna to minimize the normal vector angle between the router antenna and the initial plane, and recording that the router antenna is at the initial angle at this time;

[0043] When the fixed device points are not completely coplanar, the plane with the largest number of fixed device points is obtained as the initial plane;

[0044] It is worth noting that the antenna of a wireless router is generally an omnidirectional antenna, that is, it radiates uniformly in the horizontal direction at 360°, which is what is usually called non-directional. If the antenna direction is the vertical direction, then its spatial performance is that the wireless signal in the vertical direction is the weakest, the wireless signal in the horizontal direction is the strongest, and the coverage range of the wireless signal in the horizontal direction is the widest. Therefore, when the device is in an extension direction perpendicular to the antenna direction, the reception effect is best. Since the adjustment angle of the router antenna is limited, when the adjustment angle of the router antenna cannot be parallel to the normal vector of the initial plane, the angle between the router antenna and the normal vector of the initial plane is minimized.

[0045] It should be noted that when the fixed device points are not completely coplanar, in the process of obtaining the plane with the largest number of fixed device points, the traffic consumption of each fixed device point is compared so that the fixed device points included in the final plane are the first few fixed device points with higher traffic consumption;

[0046] The process of adjusting the angle of the router antenna includes:

[0047] Obtain the position coordinates of one end of the router antenna connected to the router body, recorded as the starting end coordinates, and obtain the position coordinates of the other end of the router antenna, recorded as the ending end coordinates; then obtain the angle vector of the router antenna according to the starting end coordinates and the ending end coordinates;

[0048] In the process of adjusting the router antenna, the position coordinate range of the terminal end coordinates of the router antenna is obtained to obtain the angle vector set of the router antenna; the normal vector of the initial plane is obtained, and the angle vector with the smallest angle with the normal vector is selected from the angle vector set, and the angle at this time is recorded as the initial angle;

[0049] It should be noted that three non-collinear points are selected on the initial plane, which are denoted as A, B, and C, respectively, to obtain two intersecting vectors AB and BC, and the vector product of vector AB and vector BC is obtained. The result of the vector product is a vector perpendicular to both vector AB and vector BC, and this vector constitutes the normal vector of the desired plane; the angle vector with the smallest cosine value of the angle with the normal vector is selected from the angle vector set, and the angle with the smallest cosine value means that the angle with the normal vector is the smallest;

[0050] Step S3: when there is a mobile device within the activity range, the position coordinates of the mobile device are acquired in real time to obtain the speed of the mobile device. When the time when the speed of the mobile device is equal to 0 exceeds a preset time threshold, the position coordinates of the mobile device at this time are recorded as the mobile device point.

[0051] It should be noted that the location of the mobile device is constantly moving. When the mobile device is still moving, it is not convenient for the router to adjust the router antenna to improve the signal reception effect of the mobile device. Only when the location of the mobile device does not change for a long time and the mobile device consumes a lot of traffic, the angle of the router antenna can be adjusted according to the current location of the mobile device to improve the mobile device's streaming signal reception effect.

[0052] The process of obtaining the speed of the mobile device point includes:

[0053] The time interval threshold T is set, and the process of obtaining the speed of the mobile device point includes:

[0054] Set a time interval threshold T, the setting range of the time interval threshold is (0s, 2s); obtain the position coordinates of the mobile device point once every time interval threshold, and record the position coordinates of the mobile device point obtained twice in succession as P1 (x1, y1, z1) and P2 (x2, y2, z2); then obtain the speed of the mobile device point at this time

[0055] Step S4: Set a flow threshold Tt, and obtain the flow consumption Tc at the mobile device point. When Tc≤Tt, obtain a plane coplanar with the fixed device point and the mobile device point, and record it as the current plane; adjust the angle of the router antenna to minimize the normal vector angle between the router antenna and the current plane;

[0056] It is understandable that when the traffic consumption of the mobile device is low, the signal strength requirement of the mobile device is not high. Then the mobile device and the fixed device are treated together, and both the mobile device and the fixed device are regarded as points. A new plane with coplanarity of the points is obtained, and the angles of all router antennas are readjusted.

[0057] The flow threshold setting process includes:

[0058] Get the traffic consumption at each fixed device point {F1, F2, ..., F m}, where F1 is the traffic consumption at the first fixed device point, and m is the total number of fixed device points; the average traffic consumption at each fixed device point is obtained Where i∈[1,m] and i is a positive integer; F ave It is recorded as the flow threshold;

[0059] Step S5: when Tc>Tt, select the antenna closest to the mobile device point from the router antennas and record it as the key antenna; adjust the angle of the key antenna so that the mobile device point is within the optimal coverage range of the key antenna;

[0060] It can be understood that when the traffic consumption of the mobile device is higher than the traffic threshold, it means that the traffic consumption of the mobile device is large, and the location where it is located requires a higher signal strength; and because the farther the location is from the router antenna, the weaker the signal strength; therefore, the router antenna closest to the mobile device point is selected as the key antenna, and the angle of the key antenna is adjusted;

[0061] The process of adjusting the angle of the focus antenna includes:

[0062] Obtain a vector perpendicular to the mobile device point, record it as a standard vector, and obtain an angle vector set of the key antenna; select an angle vector with the smallest angle with the standard vector from the angle vector set, and adjust the router antenna to meet the angle vector;

[0063] When there is more than one angle vector in the angle vector set that is parallel to the standard vector, the midpoint of the key antenna is obtained, the angle vector with the shortest distance between the midpoint and the mobile device point is selected, and the router antenna is adjusted to meet the angle vector;

[0064] It is worth noting that the total number of router antennas is n. When there are multiple mobile devices, the mobile device points with traffic consumption higher than the traffic threshold are selected and recorded as key mobile device points. The number of key mobile device points is num. If num≤n-1, num router antennas are selected respectively, and the angles of the router antennas are adjusted respectively so that they are closest to perpendicularity with the nearest mobile device point. If num>n-1, n-1 router antennas are selected, and a plane coplanar with each key mobile device point is obtained, and these n-1 router antennas are adjusted so that the angle between their normal vectors and the plane is minimized.

[0066] Environmental data collection module: obtain the user's activity range, obtain all network devices connected to the router antenna within the activity range; divide the network devices into fixed devices and mobile devices;

[0068] Mobile device monitoring module: when there is a mobile device within the activity range, the position coordinates of the mobile device are obtained in real time to obtain the speed of the mobile device. When the time when the speed of the mobile device is equal to 0 exceeds a preset time threshold, the position coordinates of the mobile device at this time are recorded as the mobile device point;
