In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides a dual-frequency concurrent communication circuit which is applied to an intelligent terminal, wherein the intelligent terminal can be a television, a PC (personal computer), a smart phone, a tablet personal computer, an electronic book reader, a portable computer and other mobile terminal equipment.
Referring to fig. 1, in an embodiment, the dual-band concurrent communication circuit includes a first wireless module 20, a second wireless module 30, and a main control chip 10. The main control chip 10, the first wireless module 20 and the second wireless module 30 are all disposed on the intelligent terminal. A first end of the main control chip 10 is connected to the first wireless module 20, and a second end of the main control chip 10 is connected to the second wireless module 30. The main control chip 10 may be connected to the first wireless module 20 and the second wireless module 30 through two wireless data interfaces, respectively. The wireless data interface may be a USB interface.
The intelligent terminal can perform wireless network connection with the dual band wireless router 40 through the first wireless module 20 or the second wireless module 30. The dual-band wireless router 40 is a wireless router that operates in 2.4GHz and 5.0GHz bands simultaneously, and has two transceiving antennas corresponding to different bands. The intelligent terminal can realize network access through the dual-frequency wireless router 40 by connecting any frequency band. It can be understood that the intelligent terminal may also perform signal search on the dual-band wireless router 40 through the two wireless modules at the same time, and connect with two frequency bands of the dual-band wireless router 40 through the two wireless modules at the same time.
The first wireless module 20 may include a first antenna 23, a first radio frequency module 22, and a first baseband processing module 21, which are connected in sequence. The first wireless module 20 may establish a first frequency channel with the dual-band wireless router 40, and a first frequency signal in the first frequency channel may be in a 2.4GHz band.
The second wireless module 30 may include a second antenna 33, a second rf module 32, and a second baseband processing module 31, which are connected in sequence. The second wireless module 30 may establish a second frequency channel with the dual-frequency wireless router 40, and a second frequency signal in the second frequency channel may be in a 5GHz band.
It is understood that in the first wireless module 20, there are a reception path and a transmission path. In the receiving path, the first antenna 23 may receive a first frequency signal from the router and send the first frequency signal to the first rf module 22, the first rf module 22 may send the first frequency signal to the first baseband processing module 21 after performing low-noise amplification and filtering on the first frequency signal, and the first baseband processing module 21 may convert the first frequency signal into a data signal recognizable by the intelligent terminal and send the data signal to the main control chip 10, for example, a display signal, an audio signal, and the like. In the transmitting path, the first baseband processing module 21 may receive a data signal sent by the main control chip 10, convert the data signal into a first frequency signal, and send the first frequency signal to the first radio frequency module 22, where after performing power amplification and filtering on the first frequency signal, the first radio frequency module 22 may send the signal to the router through the first antenna 23. That is, the main control chip 10 may implement signal transmission with the dual band wireless router 40 on the first frequency channel through the receiving path and the transmitting path in the first wireless module 20.
Similarly, the main control chip 10 can also perform signal transmission with the dual-band wireless router 40 on a second frequency channel through the receiving path and the transmitting path in the second wireless module 30. The first frequency channel is a 2.4GHz frequency band, and the second frequency channel is a 5GHz frequency band. The main control chip 10 may search for two frequency bands of the same dual-frequency wireless router 40 by starting the two wireless modules, and access the local area network of the dual-frequency wireless router 40. When the dual-band wireless router 40 can provide sufficient bandwidth, if the wireless transmission protocols corresponding to the antennas in the first wireless module 20 and the second wireless module 30 are 802.11n +2.4G 300Mbps and 802.11n +5G 300Mbps, the main control chip 10 can implement a network connection speed of 600Mbps bandwidth through the two wireless modules by using dual-band concurrent connection. And when the double-frequency concurrency is carried out, the network delay can be greatly reduced, and the use experience of a user is improved.
It should be noted that the first wireless module 20 and the second wireless module 30 are respectively connected to two different baseband processing modules and connected to the main control chip 10 through a wireless data interface, so that the main control chip 10 can simultaneously implement network communication through the two wireless modules, and the main control chip 10 is further provided with a software private protocol, which can aggregate data signals input by the two wireless modules.
Further, when the main control chip 10 is connected to the router through the two wireless modules, the signal strengths of the first frequency signal and the second frequency signal may be detected respectively. When the interference of a certain frequency channel is severe, the signal strength corresponding to the frequency signal will be significantly reduced. By detecting the signal strength, a frequency band with better signal transmission quality can be determined from the two frequency channels, and the frequency channel is selected as a main channel. It can be understood that when the main control chip 10 detects and determines that the signal intensities of the two frequency channels are both higher than the preset intensity threshold, dual-frequency concurrent communication can be achieved through the two frequency channels, respectively. Namely, when one of the two frequency channels is interfered greatly and cannot communicate normally, the other frequency channel with small interference can be automatically switched to realize signal communication without manual adjustment of a user, and communication experience of the user is improved.
The invention further provides an intelligent terminal, which comprises a switch power supply connected with the single-phase mains supply and a dual-frequency concurrent communication circuit for controlling the switch power supply to be switched on or switched off, and the structure of the dual-frequency concurrent communication circuit can refer to the embodiment, and is not described herein again. It should be noted that, since the intelligent terminal of this embodiment adopts the technical solution of the dual-frequency concurrent communication circuit, the intelligent terminal has all the beneficial effects of the dual-frequency concurrent communication circuit.
The specific embodiment of the present invention applied to the television is basically the same as the following embodiments of the dual-band signal selection method, and will not be described herein again.
Referring to fig. 2, fig. 2 is a flowchart illustrating a dual-band signal selection method according to a first embodiment of the present invention, wherein the dual-band signal selection method includes the following steps:
step S10, detecting signal strengths of the first frequency channel and the second frequency channel;
the terminal in this embodiment may be an intelligent terminal capable of performing network connection with a wireless router, and a television is taken as an example for description below. The television comprises a main control chip, a first wireless module and a second wireless module. The first wireless module and the second wireless module are respectively connected with the main control chip, and when the dual-frequency wireless router provides connection channels of two frequency bands, the main control chip can be respectively connected with the two channels of the dual-frequency wireless router through the first wireless module and the second wireless module so as to realize dual-frequency concurrent communication. It can be understood that, the first wireless module and the second wireless module can be connected with the main control chip through the USB interface, and are in communication connection with the dual-frequency wireless router through the antenna arranged on the wireless module.
When the main control chip is respectively accessed to a first frequency channel and a second frequency channel of the dual-frequency wireless router through the first wireless module and the second wireless module, the signal intensity in the two channels can be respectively detected.
Step S20, the signal strength selects a main channel path from the first frequency channel and the second frequency channel.
The main control chip can preferentially select a channel with better signal transmission quality from the two channels to realize communication by detecting the signal intensity of the two frequency channels. That is, when the main control chip detects that the signal strength of one of the two channels is not enough to implement data communication, the main control chip may close the channel and implement data communication by using the other channel as a main channel path.
Further, in the second embodiment of the dual-frequency signal selecting method according to the present invention, based on the above-mentioned embodiment shown in fig. 2, the step S10 of detecting the signal strengths of the first frequency channel and the second frequency channel includes:
step S11, calculating a first signal strength corresponding to the first frequency channel according to the first frequency signal sent by the first wireless module;
step S12, calculating a second signal strength corresponding to the second frequency channel according to the second frequency signal sent by the second wireless module.
In this embodiment, when the main control chip implements data communication with the first frequency channel of the dual-band wireless router through the first wireless module, the main control chip may calculate, through the first frequency signal sent by the first wireless module, a corresponding signal strength RSSI, that is, a first signal strength. Similarly, the main control chip may further calculate a second signal strength corresponding to the second frequency signal according to the second frequency signal. When the main control chip calculates the first signal strength and the second signal strength, a main channel can be selected from the first frequency channel and the second frequency channel according to the strength of the first signal strength and the second signal strength.
Further, referring to fig. 3, fig. 3 is a flowchart illustrating a third embodiment of the dual-band signal selection method according to the present invention, based on the embodiment shown in fig. 2, in step S20, the step of selecting the main channel path from the first frequency channel and the second frequency channel by the signal strength includes:
step S21, comparing the first signal strength and the second signal strength with a signal strength threshold respectively;
step S22, controlling the first frequency channel to close when the first signal strength is lower than the signal strength threshold;
and step S23, controlling the second frequency channel to close when the second signal strength is lower than the signal strength threshold.
In this embodiment, a signal strength threshold is pre-stored in the main control chip, and when the signal strength obtained through detection and calculation is lower than the signal strength threshold, it indicates that the interference signal in the channel is strong, and stability and accuracy of signal data transmission are easily affected. When the main control chip calculates the first signal strength and the second signal strength, the first signal strength and the second signal strength can be respectively compared with a signal strength threshold, when the first signal strength is lower than the signal strength threshold, the 2.4GHz frequency band of the dual-frequency wireless router is influenced by a strong interference signal and is not suitable for being used as a channel of data communication, at the moment, the main control chip can control the first frequency channel to be closed, and data transmission is realized through the second frequency channel. Similarly, when the second signal strength is detected to be lower than the signal strength threshold, the signal strength is detected to indicate that the 5GHz band of the dual-band wireless router is affected by the strong interference signal and is not suitable for being used as a channel for data communication, and at this time, the main control chip can control the second frequency channel to be closed, and data transmission is realized through the first frequency channel. It can be understood that the main control chip can realize the signal intensity by monitoring the signal intensity corresponding to the two channels in real time.
Further, with continuing reference to fig. 3, fig. 3 is a flowchart illustrating a fourth embodiment of the dual-frequency signal selection method according to the present invention, where after the step of comparing the first signal strength and the second signal strength with the signal strength threshold respectively, the step of S21 further includes:
step S24, when both the first signal strength and the second signal strength are higher than the signal strength threshold, performing dual-frequency signal transmission through the first frequency channel and the second frequency channel.
In this embodiment, when it is determined that the first signal strength and the second signal strength are both higher than the signal strength threshold, the main control chip may be in communication connection with two frequency bands of the dual-frequency wireless router through the two wireless modules. I.e. a dual frequency signal transmission over a first frequency channel and a second frequency channel. In the process of double-frequency signal transmission, the actual bandwidth between the main control chip and the router is the sum of the bandwidths of the two channels, and network delay can be reduced and network transmission efficiency can be improved by using double-data convergence.
In addition, the invention also provides a computer readable storage medium, on which the intelligent device distribution network program is stored. The computer-readable storage medium may be at least one of a ROM (Read-Only Memory)/RAM (Random Access Memory), a magnetic disk, and an optical disk, and includes several instructions for enabling an intelligent terminal having a main control chip to execute the dual-frequency signal selection method according to the embodiments of the present invention.
