Description

Method and electronic equipment for adjusting transmission parameters of wireless routing equipment
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an electronic device for adjusting a transmission parameter of a wireless routing device.
Background
Wireless routing is a technology that can connect terminals such as personal computers and handheld devices (e.g., mobile phones and tablet computers) to each other in a wireless manner. One of the functions of the wireless routing device is to serve as a repeater to wirelessly forward the broadband network signal received by the wireless routing device to nearby wireless routing devices, such as a notebook computer, a mobile phone supporting wireless routing, a tablet and all devices with wireless routing functions.
The antennas of the wireless routing equipment, whether the wireless routing equipment is used in a household or a commercial, are mostly omnidirectional ordinary antennas with 2 or more antennas, so that co-channel interference among different antenna signals is easily caused, and electromagnetic waves are very sensitive to the interference, so that the interference has great influence on the quality and the transmission rate of the signals, and a multipath effect phenomenon can be generated. Furthermore, omni-directional transmission has no way to concentrate the energy, resulting in less energy being emitted, which reduces transmission distance. This is also why omni-directional antennas generally do not gain very much, but directional antennas can easily achieve high gain.
A few manufacturers have used directional antennas to increase coverage, which, while increasing gain and increasing transmission distance and reducing signal interference between antennas, have the fatal disadvantage that the antennas can only be fixed at a certain angle, and if the user changes places, the user may not search for the signal at all. Such antennas are therefore currently only applicable to individual fixed scenarios, such as wireless transmission of signals from one building to a location on another building.
Due to the fact that the existing methods used by the wireless routing equipment have certain limitations, meanwhile, the wireless routing equipment is used as a home broadband entrance, the entrance position of the wireless routing equipment is more important with the development of intelligent furniture and intelligent equipment in the future, and the wireless routing equipment becomes a control hub center of a home and even a home server. There are not only requirements on signal coverage of the wireless routing device, but also high requirements on the rate.

Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the method of adjusting transmission parameters of a wireless routing device or the apparatus for adjusting transmission parameters of a wireless routing device of the present application may be applied.

At least two microphones 1012 are used to determine the location of the sound source and adjust the transmission parameters of the antenna 1011 according to the location of the sound source.

It should be noted that the method for adjusting the transmission parameter of the wireless routing device provided in the embodiment of the present application is generally executed by the wireless routing device 101, and accordingly, the apparatus for adjusting the transmission parameter of the wireless routing device is generally disposed in the wireless routing device 101.
It should be understood that the number of end devices, wireless routing devices in fig. 1 is merely illustrative. Any number of terminal devices, wireless routing devices may be present, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method of adjusting transmission parameters of a wireless routing device in accordance with the present application is shown. The method for adjusting the transmission parameters of the wireless routing equipment comprises the following steps:
in step 201, sound signals are received by at least two microphones.
In this embodiment, an electronic device on which the method of adjusting transmission parameters of a wireless routing device operates (e.g., the wireless routing device shown in fig. 1) may receive sound signals through at least two microphones. At least two microphones may constitute a microphone array unit, wherein each microphone is an omni-directional microphone. Theoretically, the more the number of microphones, the more accurate the positioning. The microphone array may be arranged in a variety of ways, for example, planar or non-planar. The planar array can be linear, rectangular, cross-shaped, circular, and the like; non-planar may be conical, spherical, etc. Typically on the order of 360 degrees of coverage. The microphones are arranged at corresponding positions in the wireless routing equipment according to a certain arrangement rule, and sound outlet holes of all the microphones are exposed on the shell. During normal operation, a user makes a sound, the sound signal is propagated through the air, and each microphone of the microphone array on the wireless routing device receives one sound signal. Due to the fact that the sound source arrives at each microphone at different time, the sound signal strength and phase received by different microphones can be different, and the difference is the basis of the microphone array for realizing sound source localization. The sound source may be an electronic device that emits sound, or may be a person who speaks or makes sound. The sound source may be multiple and the sound may be collected dynamically at predetermined time intervals to track the localized sound source location in real time.
Step 202, determining the position of the sound source according to the sound signal.
In this embodiment, the position of the sound source may be determined based on a general localization method such as a sound source localization method of controllable beams, a sound source localization method of time delay estimation, a neural network sound source localization method, and the like. The direction and distance of the sound source relative to the wireless routing device can be determined. The corresponding localization algorithm may be selected according to the number of microphones, the number of sound sources. For example, for a sound source positioning method in which a single sound source can adopt time delay estimation, the calculation amount is small, and the processing of noise is good.
In some optional implementations of the embodiment, the method further comprises converting the sound signal into an electrical signal and at least one of: amplifying the electrical signal; performing analog/digital conversion on the electric signal; ambient noise and/or echo in the electrical signal is cancelled. The amplification may be performed first and then the analog/digital conversion, or the amplification may be performed first and then the analog/digital conversion. Common denoising methods can be used for denoising to reduce interference, so that the accuracy of sound source positioning is improved. Optionally, the method may further include recognizing the voice, for example, recognizing a keyword such as "network speed slow" and the like, and then preferentially outputting a wireless signal to a sound source emitting the voice in a directional manner. The sound emitted by the electronic equipment such as keyboard sound, key sound and the like can be identified, and the wireless signal is preferentially directionally output to the electronic equipment.
In some alternative implementations of the present embodiment, the location of the sound source is determined based on the amplitude and phase of the sound signal received by each of the at least two microphones and the location of each of the at least two microphones. By comparing the time difference of the sound signals arriving at each microphone, a hyperbola with the microphone as the focus and the distance difference as the major axis can be made, and the intersection point of the hyperbola is the position of the sound source. However, the absolute time is generally difficult to measure, and therefore, the time difference of arrival of the sound signal at the microphone can be determined by measuring the amplitude and phase of the sound signal received by each of the at least two microphones, so that the position of the sound source can be determined by adopting a sound source positioning method of time delay estimation.
Step 203, adjusting the transmitting parameters of the antenna according to the position of the sound source.
In the embodiment, the transmission parameters of the antenna are adjusted according to the position of the sound source, so that the antenna can transmit directionally, and the transmission distance is increased. For a multi-antenna system, the transmission parameters of a plurality of antennas are adjusted, and the interference between the antennas can be reduced. The transmission parameters include at least one of: transmit power, transmit direction. The wireless routing device may include one antenna or may include at least two antennas. The at least two antennas may form an antenna array element, wherein each antenna is an omni-directional antenna. The principle of adjusting the transmission parameters of at least two antennas is to guide the radio signals to a specific direction to generate a space directional beam, so that the main beam of the antenna is aligned with the arrival direction of the user signals, and the side lobe or null is aligned with the arrival direction of the interference signals, thereby achieving the purposes of fully and efficiently utilizing the mobile user signals and deleting or inhibiting the interference signals. The self-adaptive antenna array formed by a plurality of antennas is adopted, when the self-adaptive antenna array works, different antenna lobes are formed through the combined work of different antennas, and the virtual antenna with different directions, angles and gains is realized, so that the self-adaptive antenna array adapts to different working environments and positions of different users, and avoids unnecessary interference. The adaptive array antenna can quickly calculate the optimal antenna combination mode by judging the working environment and sensing the position of a user during working and processing the antenna by an internal chip, thereby achieving the purpose of covering where the user wants to cover. The wireless routing equipment can easily adapt to various indoor environments through the combination of different antennas, the coverage range is enlarged, and the purpose of stabilizing the network quality is achieved.
In some optional implementations of this embodiment, adjusting the transmission parameter of the antenna includes: the amplitude and phase of the signal transmitted by the antenna are adjusted according to the position of the sound source. The power is controlled by amplitude and the direction of transmission is controlled by phase. Therefore, the amplitude and the coverage angle of the antenna can be accurately controlled. Optionally, when the wireless routing device includes at least two antennas, the transmission parameters of the antennas also need to be adjusted according to the distance between the antennas, the transmission parameters of each of the at least two antennas may be adjusted, and the transmission parameters of some antennas may also be adjusted.
In some optional implementations of this embodiment, the method further includes: determining the target transmitting power of the antenna according to the amplitude and the phase of the signal transmitted by the antenna; detecting the actual transmitting power of the antenna; and adjusting the amplitude of the signal transmitted by the antenna according to the difference value between the target transmitting power of the antenna and the actual transmitting power of the antenna. Thereby achieving closed loop control of power. When the actual transmission power is greater than the target transmission power, the actual transmission power needs to be reduced, so that the amplitude of the transmission signal needs to be reduced, and power can be saved. When the actual transmission power is smaller than the target transmission power, the actual transmission power needs to be increased, and thus the amplitude of the transmission signal needs to be increased to ensure the transmission speed. The adjustment to the position can be performed once according to the difference between the actual transmitting power and the target transmitting power. The actual transmitting power can be adjusted according to the fixed step length each time, so that the amplitude of the signal is prevented from greatly rising and falling, the power is smoother, and the transmission rate is kept stable.
With continued reference to fig. 3, fig. 3 is a schematic diagram 300 of an application scenario of the method for adjusting transmission parameters of a wireless routing device according to the present embodiment. In the application scenario of fig. 3, the user uses the terminal device 302 to emit a sound signal. The sound signals are received by microphones 3011 and 3012, respectively, on the wireless routing device 301. The position of the terminal device 302 relative to the wireless routing device 301 is determined from the amplitude and phase of the sound signal arriving at the microphones 3011 and 3012. The transmission parameters of the antennas 3013 and 3014 on the wireless routing device 301 are adjusted according to the position, so that the antennas 3013 and 3014 transmit signals to the terminal device 302 in a directional manner.
The method provided by the above embodiment of the present application locates the position of the sound source through the sound signal, and adjusts the transmission parameter of the antenna on the wireless routing device according to the position of the sound source, so as to implement directional transmission, thereby improving the data transmission speed and increasing the coverage of the wireless signal.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method of adjusting a transmission parameter of a wireless routing device is shown. The process 400 of the method for adjusting the transmission parameters of the wireless routing device includes the following steps:
step 401, sound signals are received by at least two microphones.
Step 402, determining a position of a sound source from the sound signal.
And step 403, adjusting the transmitting parameters of the antenna according to the position of the sound source.
Steps 401 and 403 are substantially the same as step 201 and 203, and therefore will not be described again.
In step 404, it is detected whether the sound source whose position has been determined transmits a packet within a predetermined time.
In this embodiment, since it is not distinguished whether or not the sound source is connected to the wireless router when the microphone detects the sound, it is possible to detect whether or not there is a packet from the terminal device at the position of the sound source determined within a predetermined time in order to detect the sound source connected to the wireless router. For example, after it is determined that the sound source is 10 meters east of the wireless routing device, it may be detected that the terminal device at the sound source has not sent a data packet to the wireless routing device within one minute, and if the data packet from the terminal device at the position of the sound source is not received, it indicates that the terminal device of the sound source has not performed wireless routing device connection, so that it is not necessary to directionally transmit a signal to the sound source. The false detection rate can be reduced, and the transmission speed is improved.
Step 405, adjusting the transmission parameters of the antenna according to the position of the sound source sending the data packet within a predetermined time.
In this embodiment, the transmission parameters of the antenna are adjusted according to the sound source position connected to the wireless routing device determined in step 402. For example, if the sound source a and the sound source B are determined in step 402, but a packet sent by the sound source a is received within one minute, it is considered that the sound source B is not connected to the wireless routing device, and therefore, only the transmission parameters of the antenna need to be adjusted according to the position of the sound source a. Optionally, the location of the sound source is re-detected at intervals and the sound source connected to the wireless routing device is re-identified. Optionally, for the case that only one sound source not connected to the wireless routing device is detected, the transmission parameters of the antenna may not be adjusted temporarily, or the transmission parameters of the antenna may be predetermined according to the position of the sound source, so as to prepare for possible subsequent connection of the wireless routing device to the sound source.
In some optional implementations of this embodiment, the method further includes: if the sound source does not send the data packet within the preset time, the adjustment of the antenna transmission parameters is not carried out. For example, sound source a and sound source B are determined in step 402, but no data packet is sent by sound source a or sound source B in one minute, then sound source a and sound source B are considered to be unconnected to the wireless routing device, and therefore antenna transmission parameters may not be adjusted for sound source a and sound source B for a while, and may be adjusted until data transmission is detected. The location of the sound source is re-detected at intervals and the sound source connected to the wireless routing device is re-identified. If it is detected that sound source a sends a data packet, the antenna transmission parameters may be adjusted for sound source a. Optionally, if the sound source does not send the data packet within the predetermined time, the transmitting parameter of the antenna is prepared according to the position of the sound source, and the adjusting mode of the transmitting parameter of the antenna is the same as the case of sending the data packet. When the data packet from the sound source is detected, the transmission parameters of the antenna are adjusted according to the prepared transmission parameters of the antenna. For example, sound source a and sound source B are determined through step 402, but neither sound source a nor sound source B sends a data packet in one minute, and antenna parameters can be prepared for sound source a and sound source B according to the condition that there is a data packet, and the antenna parameters can be prepared for the wireless connection later. When the sound source is connected with the wireless routing equipment, the antenna parameters can be quickly adjusted, so that the time delay is reduced. Optionally, if the sound source does not send the data packet within the predetermined time, the transmission parameter of the antenna is still adjusted according to the position of the sound source. For example, when there are few sound sources, the sound source a and the sound source B are determined in step 402, but the sound source a does not send a data packet within one minute, the antenna transmission parameters may also be adjusted for the sound source a, and the time delay may be reduced when the sound source is connected to the wireless routing device.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for adjusting the transmission parameters of the wireless routing device in the present embodiment highlights the steps of determining the position of the sound source connected to the wireless routing device and adjusting the transmission parameters of the antenna of the wireless routing device according to the position. The accuracy of sound source position location is improved, signals are prevented from being transmitted to a sound source which is not connected with the wireless routing equipment, and therefore the data transmission rate and the throughput of the wireless routing equipment are improved.
With further reference to fig. 5, the present application provides one embodiment of a wireless routing device as an implementation of the methods illustrated in the above figures.
As shown in fig. 5, the wireless routing device 500 of the present embodiment includes: a microphone array unit 501, a sound signal processing unit 502, an analysis calculation unit 503, a logic control unit 504, a signal transmission unit 505, and a logic control unit 506. The microphone array unit 501 includes at least two microphones for receiving a sound signal and converting the sound signal into an electrical signal; the sound signal processing unit 502 is configured to perform at least one of the following operations on the electrical signal: amplifying, A/D converting, eliminating environmental noise and echo; the analysis calculation unit 503 is configured to determine the position of the sound source and the transmission parameters of each antenna; the logic control unit 504 is configured to control different transmission channels according to the transmission parameters determined by the analysis and calculation unit, and control transmission power; the signal transmitting unit 505 is used for outputting corresponding amplitude and phase according to the logic control unit; the matrix antenna unit 506 includes at least two antennas, each of which radiates to the space according to the amplitude and phase outputted from the signal transmitting unit.
In the present embodiment, the microphone array unit 501 includes at least two microphones. The more the number of microphones, the more accurate the positioning. The microphone array may be arranged in a variety of ways, for example, planar or non-planar. The planar array can be linear, rectangular, cross-shaped, circular, and the like; non-planar may be conical, spherical, etc. Typically on the order of 360 degrees of coverage. The microphones are arranged at corresponding positions in the wireless routing equipment according to a certain arrangement rule, and sound outlet holes of all the microphones are exposed on the shell. During normal operation, a user makes a sound, the sound signal is propagated through the air, and each microphone of the microphone array on the router receives one sound signal. Due to the fact that the sound sources arrive at different microphones at different time intervals, the sound signals received by different microphones have different strength and phases, and the difference is the basis of sound localization of the microphone array.
In the present embodiment, the sound signal processing unit 502 generally uses a codec chip (a chip for converting digital and analog signals) to process the sound signal. The microphone array unit is provided with N microphones, and the selected codec chip can process N microphone channels simultaneously. Since the microphone array unit simply converts the sound signal into an electrical signal and performs certain amplification, the codec chip is required to perform other processing of the sound signal. The unit performs the operations of amplifying the signals from the microphone array unit, performing analog/digital conversion, eliminating environmental noise, eliminating echo, etc.
In this embodiment, the analysis computation unit 503 is a data processing module inside the processor of the wireless routing device. The function is to analyze the data processed by the codec chip and then calculate the position information of the sound source according to the corresponding algorithm. Then, based on the calculated position information, the unit calculates the signal strength and phase information to be carried by each antenna based on the number and position of the matrix antennas.
In this embodiment, the logic control unit 504 correspondingly controls different transmission channels according to the previously calculated signal amplitude, phase and other information, so that each channel outputs according to the calculated amplitude and phase. The actual detected power and phase information is compared with the expected value, and if the actual detected power and phase information deviates from the expected value, a compensation is made to ensure the accuracy of the output.
In the present embodiment, the signal transmitting unit 505 is controlled by the logic control unit, and each signal unit outputs corresponding amplitude and phase according to requirements. The actual output value is collected and fed back to the logic control unit 504 for corresponding compensation.
In this embodiment, the matrix antenna unit 506 is an antenna array composed of at least two antennas, and the antenna array must ensure that 360 degrees can be covered. The matrix antenna unit 506 functions such that each antenna radiates to space according to the amplitude and phase of the signal transmission unit output. The matrix antenna unit 506 also processes signals and data received from the terminals.
Referring now to fig. 6, shown is a block diagram of a computer system 600 suitable for implementing the apparatus for adjusting transmit parameters of a wireless routing device of embodiments of the present application. The device for adjusting the transmission parameters of the wireless routing device shown in fig. 6 is only an example, and should not bring any limitation to the functions and the scope of use of the embodiments of the present application.
