Or, when the maintenance personal in the station overhauls the station using the maintenance instrument of real-time transmission, when passenger's cell-phone or other terminal quantity are more around, the data demand at all terminals in the region of maintenance personal place can be greater than the data transmission volume that sets up in advance, and then so the data transmission rate at all terminals in the region of maintenance personal place can all be influenced, and then the data communication's that can make the maintenance instrument quality and speed are lower, influence the demonstration of train number information.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart illustrating a method for controlling a beam direction of a WiFi device according to an embodiment of the present disclosure. The method for controlling the beam direction of the WiFi equipment is applied to a space provided with a plurality of WiFi equipment and is used for controlling the beam direction of the WiFi equipment.
Fig. 2 is a scene schematic diagram provided in the embodiment of the present application. In the square space shown in the figure, there are router devices such as router 11-router 19, and the coverage area of each router is shown by a ring shown in the figure, and the center of the ring is the center of the corresponding router. The target terminal is 10.
The method provided by the embodiment of the application can be applied to any wifi device in fig. 2, or can also be applied to a server connected with the wifi device. In the embodiment of the present application, a server is taken as an example. The server is connected with all the wifi devices and is connected with all the terminals through the wifi devices.
As shown in fig. 1, the method may include the following steps.
S101, the server acquires the coverage area of each WiFi device in the space.
In the embodiments of the present application, the space refers to a larger space that is independent, for example: spaces such as railway stations, airports, or large malls, in which large mobile terminals are often located due to traffic.
The coverage area of the WiFi device refers to the effective radiation range of the WiFi device, and the coverage area of the WiFi device is different because the model, power and communication mode of each WiFi device are different (for example: 5G, or 2.4G).
As shown in fig. 2, there are router devices such as router 11-router 19 in the square space shown in the figure, and the coverage area of each router is shown by a ring shown in the figure, and the center of the ring is the center of the corresponding router. The target terminal is 10.
In the embodiment of the present application, the coverage area of the WiFi device may be obtained in the following manners, including the following:
s1011, the server obtains the device information sent by each WiFi device.
The device information includes at least: the installation position of the WiFi device in the space, and the radiation distance of the WiFi device. In the embodiment of the present application, the installation position refers to a position of the WiFi device in a coordinate system of the space by reference.
The radiation distance refers to a range supported by the WiFi device itself, where the radiation distance is not the maximum connection range of the WiFi device, but refers to a range that ensures a reliable data connection speed, and in practical applications, the ratio may be reduced on the basis of the maximum connection range, for example: the radiation distance may be 60% of the maximum connection range.
And S1012, the server generates a coverage area of each WiFi device in the space according to the installation position and the radiation distance of each WiFi device.
And in the coordinate system of the space, drawing a circle according to the radiation distance by taking the coordinate of the installation position of the WiFi equipment as a circle center, so as to obtain the coverage area.
And S102, the server acquires transmission data between the target terminal and any one WiFi device.
In this embodiment of the application, the transmission data may be probe data of a communication connection between the target terminal and any one of the WiFi devices, for example: and testing packet loss rate, transmission delay, transmission rate and the like. The detection data is not actual data of the terminal and the WiFi device, but transmission of test data which can be performed after the terminal is connected to the WiFi device is performed, so as to obtain a connection condition with the WiFi device. In actual operation, a detection request may be sent to a connected terminal through the WiFi device, and then transmission of detection data may be performed according to the detection request.
S103, the server obtains the direction adjustment priorities of all the terminals in the space.
In this space, a direction adjustment priority may be set for each terminal, for example: ordinary passenger, the adjustment priority can set up to 0 lowest, and to station staff's cell-phone, the direction adjustment priority is higher than the passenger, can set up to 1, and to station maintainer's cell-phone, the direction adjustment priority can be higher than ordinary station staff, and the priority can set up to 2, and to the terminal in the intelligent robot of station, because operating frequency is higher, so, the direction adjustment priority is the highest, can set up to 3.
In this embodiment of the application, the direction adjustment priorities of all the terminals in the space may be sent to one wifi device or multiple wifi devices in fig. 2, and the direction adjustment priorities collected by all the wifi devices may also be shared to each wifi device.
S104, the server judges whether the direction adjustment priority of the target terminal is higher than that of terminals outside the target terminal in the space.
The role of the direction adjustment priority is that when two terminals of priority 1 and priority 2 are at an interval of 3 meters, if the beam direction of the wifi device needs to be adjusted, the terminal which meets priority 2 is prioritized, that is, the beam direction is aligned to the terminal with priority 2.
And S105, if the direction adjustment priority of the target terminal is higher than that of terminals outside the target terminal in the space, the server judges whether the target terminal in the space meets the triggering condition according to the transmission data.
In an embodiment of the present application, the determination of the triggering condition of this step may be:
at Stp01, the server checks whether or not to extract a transmission direction trigger request sent by the target terminal from the transmission data.
In the embodiment of the present application, the method triggering request is that when a user performs a test, the terminal finds that the current WiFi connection cannot meet the requirement, for example: the transmission speed is slow, repeated connection occurs, and the direction trigger request can be manually sent.
In a specific application, a terminal that can trigger a direction trigger request is not a general handset but a specific terminal, for example: network operation and maintenance personnel at railway stations and airports, or equipment operators who need to use the network of railway stations and airports for intelligent control, for example: the robot sweeping factory of a base train station or an airport, the automatic patrol instrument factory, the intelligent video monitoring mobile platform factory and the like.
Before the devices operate, a special terminal needs to be used for moving in space so as to detect the network anywhere, and once the WiFi network transmission at a certain position is detected to be bad, a direction trigger request can be generated and sent to the WiFi device.
Stp02, if the server receives the direction trigger request sent by the target terminal, the server detects the number of terminals in the location area where the target terminal is located.
All WiFi equipment in the position area where the target terminal is located can be determined, and then the number of terminals in the position area where the target terminal is located can be determined through the searched terminals connected with the WiFi equipment.
Stp03, the server judges whether the number of terminals in the location area of the target terminal exceeds a preset number threshold.
The number of terminals may be in the order of tens of stations. For example: 50 stands.
Stp04, if the number of terminals in the location area of the target terminal exceeds a preset number threshold, the server determines the trigger condition that the target terminal in the space satisfies.
In the embodiment of the application, when a target terminal used by a user triggers a direction trigger request, the number of terminals in the area needs to be judged, and if the number of terminals exceeds a preset number threshold, it can be determined that a trigger condition is met.
In another embodiment of the present application, the trigger condition of this step may be determined in the following manner:
stp11, the server extracts the data transmission parameters of the target terminal from the transmission data.
In the embodiment of the present application, the data transmission parameter may be a packet loss rate, a transmission delay, a transmission rate, or other parameters.
Stp12, the server determines whether the data transmission parameter is less than a corresponding parameter threshold.
The parameter threshold is a value between good and bad communication conditions of the target terminal, and can be set by manufacturer personnel according to experience or automatically according to historical conditions.
Stp13, if the data transmission parameter is smaller than the corresponding parameter threshold, the server detects the number of terminals in the location area where the target terminal is located.
Stp14, the server judges whether the number of terminals in the location area of the target terminal exceeds a preset number threshold.
Stp15, if the number of terminals in the location area of the target terminal exceeds a preset number threshold, the server determines the trigger condition satisfied by the target terminal in the space.
Compared with the step of stp01-04, the scheme does not need manual triggering by a user, and automatically triggers according to the data transmission condition of the target terminal and the area of the position of the target terminal, so that the method is more intelligent.
In the foregoing stp01-04 embodiment and stp11-stp15 embodiment, in the embodiment in the community, when it is determined that the number of terminals in the location area where the target terminal is located exceeds the preset number threshold, the communication quality of the terminals may be further determined to verify whether the problem of communication congestion really occurs, and for this purpose, the step may further include:
stp21, the server judges whether the data transmission rate of any terminal in the location area of the target terminal is lower than the preset rate;
stp22, if the data transmission rate of any one terminal is lower than the preset rate, the server executes the step of determining the trigger condition that the target terminal in the space is ready to satisfy.
For this reason, it is determined that the trigger condition is satisfied only if the communication quality is degraded when the number of terminals is overloaded.
In step S105, if it is determined whether the trigger condition of the target terminal in the space is satisfied according to the transmission data, step S106 is executed, otherwise, the process is ended.
S106, the server acquires the communication connection information between one or more WiFi devices in the space and the target terminal.
The step can be collected by wifi equipment and then sent to the target terminal, or a server connected with the target terminal, and the like.
S107, the server determines the current position and at least one historical reference position of the target terminal in the space according to the communication connection information.
The current position is the position of the target terminal at the current moment, and the historical reference position is the position of the target terminal before the target terminal moves to the current position.
Referring to FIG. 3, k1-k6 is a plurality of historical reference positions. The acquisition intervals of the plurality of historical reference positions are the same.
In one embodiment of the application, for the service personnel, when the handheld target terminal moves in the space, the target terminal also moves in the space. In specific application, a spatial positioning technology can be adopted to confirm the position of the target terminal. In addition, the relative distances between the target terminal and the plurality of WiFi devices can be determined according to the signal strength between the target terminal and the plurality of WiFi devices, then, the circle is drawn by taking the position of each WiFi device as the center of a circle and the corresponding relative distance as the radius, and the intersected position of the circles is the position of the target terminal.
And S108, the server determines the motion trail of the target terminal according to the historical reference position.
The motion trajectory of the target terminal can be obtained by smoothly connecting the plurality of historical reference positions, as shown in fig. 3. The curve in the figure is a drawn motion track.
And S109, the server predicts the predicted position or the predicted area position of the target terminal when moving in the space according to the motion trail.
Referring to fig. 3, the brilliant motion trajectory is extended to obtain a dotted line portion in fig. 3, and then k7 in the figure is obtained as a predicted position according to the predicted interval, and the predicted position is a preset region around the preset position.
S110, the server uses the current position as the target position, or uses the predicted position or predicted area position as the target position, or uses the current position and the predicted area position as the target position.
S111, the server searches at least one WiFi device covering the target position.
According to the position of the WiFi equipment and the corresponding coverage radius, all the WiFi equipment covering the target position can be found.
And S112, the server searches the WiFi equipment with the maximum signal intensity at the target position in the at least one WiFi equipment as the target WiFi equipment.
And S113, the server generates a beam direction adjusting instruction corresponding to the target WiFi equipment and sends the beam direction adjusting instruction to the corresponding WiFi equipment so as to control the beam direction of the wireless signal of the WiFi equipment to point to the target position.
After the target position is determined, the beam direction of the wireless signal of the found WiFi device with the largest signal strength can be controlled to point to the target position.
Referring to fig. 4, the target terminal 10 finally determines that the signal strength of the router 12 is the maximum, and the router 12 is provided with a beam antenna, and referring to fig. 4, the beam antenna of the router 12 adjusts the beam direction to point to the target terminal 10.
For a wireless router, beam forming is a technology for a transmitting end to perform directional transmission according to the position of a receiving end, and a router adopting the beam forming technology must have multiple antennas. And processing the signals received by the plurality of antennas at the receiving end of the wireless equipment by adopting a certain algorithm, so as to improve the signal strength of the receiving end of the wireless equipment. That is, the beamforming technique must be supported by both the wireless router and the wireless device to be truly robust.
In the transmission router, because there is no beam forming technology, the router sends out an omnidirectional signal in the form of radio waves, and if the signal of the router is strong enough, the coverage of all devices can be realized.
However, better WiFi reception is required for each device, but in a complex environment, various factors always interfere with beamforming, resulting in weaker signals. For this reason, in the IEEE published 802.11ac specification, a standardized method for using beamforming in a WiFi device is formed, so that the WiFi device can support beamforming, and further, signal enhancement can be performed on a certain position or area in space.
According to the method provided by the embodiment of the application, through monitoring the wifi device and the target terminal in the space, when the target terminal needs higher communication requirements, the direction of the wave beam of a certain wifi device can be adjusted, and the direction of the wave beam points to the position of the target terminal, so that the communication quality of the target terminal is ensured.
