The signal transmission method provided by the embodiments of the present application is used for the wireless routing device 120 shown in fig. 1.
Referring to fig. 2, a schematic structural diagram of a wireless routing device provided in an exemplary embodiment of the present application is shown, which may be implemented as the wireless routing device 120 in fig. 1.
Optionally, the wireless routing device 120 includes: a processor 122, a memory 124, and an antenna 126.

In the embodiment of the present application, the antenna 126 is used for transmitting a WiFi signal, and at least two antennas 126 are disposed on the wireless routing device 120. Optionally, at least two antennas 126 correspond to the same or different transmission frequencies, for example, a part of the antennas are used for transmitting 2.4GHz WiFi signals, and another part of the antennas are used for transmitting 5GHz WiFi signals.

Of course, the wireless routing device 120 may further include other components such as a power supply component, an indicator light component, a Near Field Communication (NFC) component, and the embodiment of the present application is not limited to the specific structure of the wireless routing device 120.
Referring to fig. 4, a flow chart of a signal transmission method according to an exemplary embodiment of the present application is shown. This embodiment is illustrated with the method applied to the wireless routing device 120 shown in fig. 1. The method comprises the following steps:
In a possible implementation manner, after receiving a wireless connection establishment request sent by a target terminal, a wireless routing device detects whether a connection password included in the wireless connection establishment request is consistent with a preset connection password, and establishes a wireless connection with the target terminal when the connection password is consistent with the preset connection password.
The connection state information is used for indicating the current wireless network connection state of the target terminal, wherein the connection state information at least comprises the WiFi signal strength of the WiFi signal currently received by the target terminal. The WiFi signal strength and the distance from the target terminal to the wireless routing equipment are in a negative correlation relationship, and the WiFi signal strength is influenced by obstacles between the target terminal and the wireless routing equipment.
Optionally, the connection status information may further include other information used for indicating the connection status of the wireless network, such as a terminal identifier (unique identifier terminal, which may be an MAC address of the terminal) of the target terminal, a terminal network speed of the target terminal, and a network delay (such as a ping value), and the specific content included in the connection status information is not limited in this embodiment.
In a possible implementation manner, after the target terminal establishes wireless connection with the wireless routing device, the current WiFi signal strength is acquired at intervals of a predetermined time interval, and the connection state information containing the WiFi signal strength is sent to the wireless routing device.
In another possible implementation, in order to avoid that the subsequent wireless routing device frequently adjusts the antenna due to the fact that the terminal sends the connection state information (the WiFi signal strength may frequently change during the movement), after the target terminal establishes wireless connection with the wireless routing device, the movement state is determined according to sensor data (such as acceleration data), if the operation state is a static state and the duration of the static state reaches a duration threshold, the current WiFi signal strength is obtained, and the connection state information including the WiFi signal strength is sent to the wireless routing device.
Optionally, after receiving the connection status information, the wireless routing device acquires the WiFi signal strength included in the connection status information, and detects whether the WiFi signal strength is lower than a first strength threshold (for example, -50 dBm). If the current signal is lower than the preset threshold value, determining that the WiFi signal at the target terminal is not good, and executing a step 403; and if so, determining that the WiFi signal at the target terminal is good, and keeping the current working state of the antenna.
In order to enhance the WiFi signal at the target terminal and thereby improve the network access quality of the target terminal, the wireless routing device determines a target antenna from the at least two antennas according to the position (direction relative to the wireless routing device) of the target terminal, and adjusts the target antenna. Optionally, the target antenna is at least one antenna.
Optionally, the adjustment mode for the target antenna includes at least one of the following: adjusting the signal radiation direction of the target antenna and adjusting the signal radiation intensity of the target antenna.
And step 404, transmitting a WiFi signal through the adjusted target antenna.
Further, after the wireless routing device adjusts the target antenna, the wireless routing device transmits a WiFi signal through the target antenna, and detects whether the WiFi signal strength at the terminal reaches a first strength threshold value according to the connection state information subsequently transmitted by the target terminal. If the target antenna is not adjusted, the target antenna is continuously adjusted.
Different from the prior art in which the WiFi signal strength is simply improved by improving the overall transmission power of the wireless routing equipment, in the embodiment of the application, the wireless routing equipment only needs to adjust the signal radiation direction and/or the signal radiation strength of part of the antennas when the WiFi connection quality of the terminal is poor, the transmission power of all the antennas does not need to be improved, and the power consumption of the wireless routing equipment is reduced on the premise of improving the WiFi signal strength of the terminal.
Under a possible application scene, a user uses a mobile phone to connect a wireless router to surf the internet at home, and when the user enters a room, WiFi signals are blocked by the wall of the room, so that the WiFi signals of the mobile phone are weak in strength. At the moment, the wireless router improves the WiFi signal intensity at the mobile phone by adjusting the signal radiation direction and/or the signal radiation intensity of part of the antennas, and other antennas keep the original working state, so that the problem of power consumption increase caused by improving the signal radiation intensity of all the antennas is avoided.
To sum up, in the embodiment of the present application, after the wireless routing device establishes wireless connection with the target terminal, the connection state information sent by the target terminal is obtained, and when the connection state information indicates that the WiFi signal strength is weak, the target antenna of the at least two antennas is adjusted according to the direction of the target terminal relative to the wireless routing device, so that the WiFi signal is transmitted through the adjusted target antenna; compared with the prior art in which the overall transmission power of the wireless routing device is simply increased, the wireless routing device in the embodiment of the application dynamically adjusts part of the antennas according to the strength of the WiFi signal received by the connected terminal so as to increase the strength of the WiFi signal received by the target terminal, thereby improving the network access quality of the target terminal, contributing to reducing the overall power consumption of the wireless routing device, and prolonging the service life of the wireless routing device.
Optionally, the wireless routing device may provide an antenna adjustment service only for the specific terminal, and accordingly, after receiving the connection state information sent by the target terminal through the wireless connection, the wireless routing device acquires the terminal identifier included in the connection state information. If the terminal identification belongs to the terminal list, when the WiFi signal strength is lower than a first strength threshold value, executing a step of adjusting a target antenna in at least two antennas according to a first relative direction of the target terminal; if the terminal identification does not belong to the terminal list, the wireless routing equipment keeps the current antenna configuration. Optionally, the terminal list is set by the user, for example, the terminal list includes the MAC addresses of the frequently connected terminals.
In a possible implementation manner, a plurality of antennas are arranged on the wireless routing device, each antenna is connected with the rotating component, and the rotating component can drive part or all of the antennas to rotate. When the WiFi signal strength of the target terminal is detected to be weak, the wireless routing equipment firstly determines the relative position of the target terminal, then determines the target antenna from the multiple antennas according to the relative position, and further adjusts the target antenna, so that the signal strength at the target terminal is improved. The following description will be made by using exemplary embodiments.
Referring to fig. 5, a flow chart of a signal transmission method according to another exemplary embodiment of the present application is shown. This embodiment is illustrated with the method applied to the wireless routing device 120 shown in fig. 1. The method comprises the following steps:
The implementation of this step may refer to step 401, and this embodiment is not described herein again.
In the working state, each antenna transmits a WiFi signal to the corresponding signal radiation direction, and the WiFi signal strength at the signal radiation direction is strongest, so that the wireless routing equipment drives the antenna to rotate through the rotating component, and determines the relative position of the target terminal according to the connection state information (WiFi signal strength) received in the rotating process.
In a possible implementation manner, the wireless routing device sends a status information reporting instruction to each connected terminal, and instructs each terminal to continuously send connection status information containing the real-time WiFi signal strength for a predetermined time (for example, 4 s). Meanwhile, the wireless routing equipment drives one antenna of the at least two antennas to rotate through the rotating assembly within a preset time length, receives at least one piece of connection state information sent by the target terminal through the antenna in the rotating process, and records the information receiving time and the corresponding relation between the rotating direction of the rotating assembly and the connection state information.
It should be noted that, when the wireless routing device establishes wireless connections with multiple terminals at the same time, the wireless routing device determines the connection state information sent by each terminal according to the terminal identifier included in the connection state information.
As shown in fig. 6, the wireless routing device 61 drives the first antenna 611 to rotate clockwise from the northeast direction through the rotating component, and receives 4 pieces of connection status information sent by the target terminal 62 in the rotating process. Illustratively, the correspondence relationship between the information receiving time and the connection state information stored in the wireless routing device and the rotation direction is shown in table one.
Watch 1
| Time of information reception | Direction of rotation | Connection status information |
| 17:37:11 | Northeast | -120dBm |
| 17:37:12 | Southeast China | -100dBm |
| 17:37:13 | Southwest | -90dBm |
| 17:37:14 | Northwest of China | -100dBm |
In a possible implementation manner, the wireless routing device determines connection state information sent by the target terminal according to a terminal identifier included in the connection state information, and obtains WiFi signal strength included in the connection state information, where the WiFi signal strength is real-time WiFi signal strength at the target terminal at different times.
In step 504, a first relative direction is determined according to the rotation direction of the rotating assembly at the moment of receiving the information corresponding to the maximum WiFi signal strength.
Since the WiFi signal strength at the position facing the antenna signal radiation direction is the maximum, the wireless routing device may determine the information receiving time corresponding to the maximum WiFi signal strength as the time when the antenna faces the target terminal, and further determine the rotation direction of the information receiving time rotating assembly as the first relative direction of the target terminal.
Illustratively, in combination with the data shown in table one, the wireless routing device determines the information receiving time "17: 37: 13" corresponding to the maximum WiFi signal strength "-90 dBm" as the time when the antenna is facing the target terminal, so as to determine the rotation direction "southwest" of the antenna at that time as the first relative direction.
Of course, the wireless routing device may determine the first relative direction of the target terminal by other means (such as GPS positioning) besides the above-mentioned means, and the specific means for determining the first relative direction is not limited in this application.
Optionally, after determining the first opposite direction of the target terminal, the wireless routing device detects whether the maximum WiFi signal strength is lower than a first strength threshold, and if so, performs step 505.
In a possible implementation manner, since the wireless routing device may be connected to multiple terminals at the same time, in order to avoid network access quality to other terminals in the process of adjusting the antennas, the wireless routing device determines, from at least two antennas, a target antenna that has the smallest influence on the other terminals, so as to reduce the influence on the other terminals when subsequently adjusting the target antenna. On the basis of fig. 5, as shown in fig. 7, the present step may include the following steps.
And 505A, acquiring a second relative direction of other terminals connected with the wireless routing device.
In order to avoid the problem that the WiFi signal strength at other terminals is reduced due to adjustment of antennas corresponding to other terminals (the signal radiation direction of the antennas is consistent with the terminal direction), the wireless routing device acquires the second relative direction of the other terminals, so as to determine the antennas corresponding to the other terminals in the following. The other terminals are terminals which have already established wireless connection with the wireless routing device and perform network access, and the second opposite direction is the direction of the other terminals relative to the wireless routing device.
It should be noted that, the step 502 to the step 504 may be referred to for determining the second relative direction corresponding to other terminals, and details are not described herein again in this embodiment.
Illustratively, in the environment shown in fig. 6, the wireless routing device 61 also establishes a connection with the other terminal 63, and therefore, the second relative direction in which the wireless routing device 61 acquires the other terminal 63 is "southeast".
And 505B, determining a candidate antenna of the at least two antennas according to the second opposite direction and the signal radiation direction corresponding to each antenna, wherein a first included angle between the signal radiation direction corresponding to the candidate antenna and the second opposite direction is larger than an included angle threshold value.
Further, the wireless routing equipment acquires signal radiation directions corresponding to the current antennas, and selects a signal radiation direction with small influence on a second opposite direction signal from the acquired signal radiation directions, so that the antenna corresponding to the selected signal radiation direction is determined as a candidate antenna.
In one possible implementation, the wireless routing device calculates a first angle between the second relative direction and each signal radiation direction, and detects whether the first angle is greater than an angle threshold. If so, determining that the influence of the signal emitted by the antenna to the signal radiation direction on the signal strength at the second opposite direction is small, and determining the antenna corresponding to the signal radiation direction as a candidate antenna; if the signal intensity is smaller than the first predetermined value, it is determined that the signal emitted from the antenna in the signal radiation direction has a larger influence on the signal intensity in the second opposite direction, and thus the antenna corresponding to the signal radiation direction is prevented from being adjusted (rotation adjustment).
Illustratively, in the environment shown in fig. 6, the signal radiation direction corresponding to the first antenna 611 on the wireless routing device 61 is "west", the signal radiation direction corresponding to the second antenna 612 is "southeast", the signal radiation direction corresponding to the third antenna 613 is "northeast", and the signal radiation direction corresponding to the fourth antenna 614 is "northwest". When the second relative direction corresponding to the other terminal 63 is "southeast", the wireless routing device 61 calculates that the included angle between the signal radiation direction corresponding to the first antenna 611 and the second relative direction is 135 °, the included angle between the signal radiation direction corresponding to the second antenna 612 and the second relative direction is 0 °, the included angle between the signal radiation direction corresponding to the third antenna 613 and the second relative direction is 90 °, and the included angle between the signal radiation direction corresponding to the fourth antenna 614 and the second relative direction is 180 °. If the angle threshold is 45 °, the wireless routing device 61 determines the first antenna 611, the third antenna 613, and the fourth antenna 614 as candidate antennas.
Optionally, if the first included angle between the signal radiation direction corresponding to each antenna and the second opposite direction is greater than the included angle threshold, the wireless routing device determines the antenna corresponding to the largest first included angle as the candidate antenna.
And 505C, acquiring a second included angle between the signal radiation direction corresponding to the candidate antenna and the first relative direction.
Through steps 505A and 505B, the wireless routing device screens out a plurality of candidate antennas having small influence on the signal of the connected terminal, thereby reducing the influence on the connected terminal caused by subsequent antenna adjustment (signal radiation direction).
Further, the wireless routing device obtains a second included angle between the signal radiation direction corresponding to the candidate antenna and the first relative direction, where the second included angle is an angle that the antenna needs to rotate when the signal radiation direction of the candidate antenna is adjusted to the first relative direction.
Illustratively, in the environment shown in fig. 6, the wireless routing device 61 calculates that a second angle between the signal radiation direction corresponding to the first antenna 611 and the first relative direction is 45 °, a second angle between the signal radiation direction corresponding to the third antenna 613 and the first relative direction is 180 °, and a second angle between the signal radiation direction corresponding to the fourth antenna 614 and the first relative direction is 90 °.
And step 505D, determining a target antenna in the candidate antennas according to the second included angle, where an included angle between the signal radiation direction corresponding to the target antenna and the first relative direction is smaller than included angles between the signal radiation directions corresponding to the other candidate antennas and the first relative direction.
In order to further reduce the angle of rotation required during subsequent adjustment of the target antenna, the wireless routing equipment screens the target antenna from the candidate antennas according to the second included angle. In one possible implementation, the wireless routing device sorts the candidate antennas according to the ascending order of the second included angle, so that the first n (n ≧ 1) candidate antennas are determined as the target antennas.
In connection with the example in step 505C described above, in the environment shown in fig. 6, the wireless routing device 61 determines the first antenna 611 as the target antenna.
Of course, the wireless routing device may also determine all the determined candidate antennas as target antennas, which is not limited in this embodiment.
Since the WiFi signal strength at a certain position is related to the signal radiation direction and the signal radiation strength of the antenna, after the target antenna is determined, the wireless routing device improves the WiFi signal strength at the target terminal by adjusting the signal radiation direction and/or the signal radiation strength of the target antenna.
In order to further reduce the power consumption of the wireless routing device, the wireless routing device adjusts the target antenna by adopting an adjusting logic of 'radiating direction first and then radiating intensity'. On the basis of fig. 5, as shown in fig. 7, the present step may include the following steps.
The reason that the signal strength at the target terminal is weak may be that the antenna is not directly facing the target terminal, and therefore, the wireless routing device drives the target antenna to rotate through the rotating component, so that the signal radiation direction of the target antenna is the first relative direction in which the target terminal is located.
Optionally, the wireless routing device calculates a rotation direction and a rotation angle of the antenna according to the current signal radiation direction and the first relative direction of the target antenna, so as to send a rotation instruction to the rotating assembly according to the rotation direction and the rotation angle of the antenna, and instruct the rotating assembly to drive the target antenna to rotate.
For example, in connection with the example in the above steps, in the implementation environment shown in fig. 6, the wireless routing device determines that the rotation direction of the antenna 611 is counterclockwise rotation by 45 °.
Optionally, after the signal radiation direction of the target antenna is adjusted to the first opposite direction, the wireless routing device continues to detect whether the WiFi signal strength at the target terminal is lower than the first strength threshold, if so, step 506B is executed, and if so, the adjustment of the target antenna is stopped.
In step 506B, if the WiFi signal strength after adjusting the target antenna is less than the first strength threshold, the transmit power of the target antenna is adjusted.
In addition to the signal radiation direction, the signal radiation intensity of the antenna also affects the WiFi signal intensity at the terminal (especially in the case of obstacle obstruction). Therefore, when the WiFi signal strength is still less than the first strength threshold after the target antenna is adjusted, the wireless routing device further adjusts the transmission power of the target antenna, so as to improve the signal radiation strength of the target antenna. Wherein, the transmitting power of the target antenna after the up-regulation is less than or equal to the maximum transmitting power.
And step 507, transmitting a WiFi signal through the adjusted target antenna.
The step 404 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In this embodiment, wireless routing equipment drives the antenna rotation through rotatory subassembly to according to the change situation of rotatory in-process target terminal department wiFi signal strength, determine the relative position with wireless routing equipment of target terminal, so that follow-up adjusts appointed antenna based on this position, improved the accuracy of antenna adjustment, and help reducing wireless routing equipment's whole consumption.
In addition, in this embodiment, the wireless routing device screens out candidate antennas that have a small influence on the WiFi signal strength at other terminals according to second relative directions corresponding to the other terminals, and further selects a target antenna from the candidate antennas, thereby reducing the influence on the other terminals when subsequently adjusting the target antenna.
In addition, the wireless routing equipment adopts the adjusting logic of 'radiation direction first and radiation intensity later' to adjust the target antenna, so that the problem of power consumption improvement of the equipment caused by directly increasing the radiation intensity of the target antenna is avoided.
If the WiFi signal strength at the terminal is continuously increased after reaching a certain strength threshold, the network access quality of the terminal is no longer improved, but the power consumption of the wireless routing device is too large. Therefore, in a possible implementation, on the basis of fig. 5, as shown in fig. 8, step 504 may further include the following steps
And step 508, if the WiFi signal strength is higher than a second strength threshold, adjusting the transmission power of the antenna corresponding to the first relative direction downward, where the second strength threshold is greater than the first strength threshold, and after the transmission power is adjusted downward, the first strength threshold is not less than the WiFi signal strength and not more than the second strength threshold.
In one possible implementation, when detecting that the WiFi signal strength at the target terminal is higher than the second strength threshold (such as-30 dBm), the wireless routing device adjusts the transmission power of the antenna corresponding to the first relative direction (the signal radiation direction is consistent with the first relative direction) downward according to the first relative direction corresponding to the target terminal, so as to reduce the WiFi signal strength at the target terminal and ensure the network access quality of the target terminal.
In step 509, if the first strength threshold is less than or equal to the WiFi signal strength and less than or equal to the third strength threshold, and the terminal network speed is greater than the network speed threshold, the signal radiation direction of the target antenna is adjusted to the first relative direction, and/or the transmission power of the target antenna is adjusted up.
The first strength threshold is the lowest WiFi signal strength when the terminal is normally accessed to the network, and for the terminal occupying higher network speed, the WiFi signal strength at the terminal reaches the first strength threshold and cannot reach better network access quality.
Therefore, in order to further improve the network access quality of the terminal occupied by the high network speed, the wireless routing device acquires the terminal network speed of the target terminal and detects whether the terminal network speed is greater than a network speed threshold (such as 500 kb/s). If so, determining that the target terminal is a high-network-speed occupied terminal, adjusting the signal radiation direction of the target antenna to be a first relative direction, and/or adjusting the transmission power of the target antenna to enable the WiFi signal strength at the target terminal to be larger than a third strength threshold (such as-60 dBm); if the current antenna setting is smaller than the preset threshold value, the target terminal is determined to be not the high-network-speed occupied terminal, and the current antenna setting is kept.
In the embodiment, when the WiFi signal intensity of the wireless routing equipment at the terminal is too strong, the transmitting power of the antenna is adjusted downwards, so that the overall power consumption of the wireless routing equipment is reduced while the network access quality of the terminal is ensured; meanwhile, for a target terminal occupied at a high network speed, the wireless routing equipment adjusts the radiation direction and the radiation intensity of the antenna, so that the WiFi signal intensity at the target terminal is improved, and the network access quality of the target terminal is further improved.
