本发明提供一种双频并发通讯电路,应用于智能终端中,该智能终端可以是电视、PC、智能手机、平板电脑、电子书阅读器、便携计算机等可移动式终端设备等。The present invention provides a dual-frequency concurrent communication circuit, which is applied to an intelligent terminal, and the intelligent terminal can be a mobile terminal device such as a TV, a PC, a smart phone, a tablet computer, an e-book reader, a portable computer, and the like.

参见图1,在一实施例中,所述双频并发通讯电路包括第一无线模块20、第二无线模块30以及主控芯片10。主控芯片10、第一无线模块20和第二无线模块30均设置于智能终端上。主控芯片10的第一端与第一无线模块20连接,主控芯片10的第二端与第二无线模块30连接。其中,主控芯片10可以分别通过两个无线数据接口与第一无线模块20和第二无线模块30连接。该无线数据接口可以为USB接口。Referring to FIG. 1 , in an embodiment, the dual-frequency 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. The first end of the main control chip 10 is connected to the first wireless module 20 , and the second end of the main control chip 10 is connected to the second wireless module 30 . The main control chip 10 can be connected to the first wireless module 20 and the second wireless module 30 through two wireless data interfaces, respectively. The wireless data interface can be a USB interface.

智能终端可以通过第一无线模块20或第二无线模块30与双频无线路由器40进行无线网络连接。其中,双频无线路由器40即为同时工作在2.4GHz和5.0GHz频段的无线路由器,其具有两个对应不同频段的收发天线。智能终端通过连接任一频段均可以通过双频无线路由器40实现网络接入。可以理解的是,智能终端还可以通过两个无线模块同时对双频无线路由器40进行信号搜索,并通过两个无线模块同时与双频无线路由器40的两个频段进行连接。The smart 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 . Among them, the dual-band wireless router 40 is a wireless router that works in the 2.4GHz and 5.0GHz frequency bands at the same time, and has two transceiver antennas corresponding to different frequency bands. By connecting to any frequency band, the intelligent terminal can realize network access through the dual-band wireless router 40 . It can be understood that the smart terminal can also perform signal search for the dual-band wireless router 40 through the two wireless modules at the same time, and connect with the two frequency bands of the dual-band wireless router 40 through the two wireless modules at the same time.

第一无线模块20可以包括依次连接的第一天线23、第一射频模块22以及第一基带处理模块21。第一无线模块20可以与双频无线路由器40建立第一频率信道,第一频率信道中的第一频率信号可以为2.4GHz频段。The first wireless module 20 may include a first antenna 23 , a first radio frequency module 22 and a first baseband processing module 21 connected in sequence. The first wireless module 20 may establish a first frequency channel with the dual-band wireless router 40, and the first frequency signal in the first frequency channel may be the 2.4 GHz frequency band.

第二无线模块30可以包括依次连接的第二天线33、第二射频模块32以及第二基带处理模块31。第二无线模块30可以与双频无线路由器40建立第二频率信道,第二频率信道中的第二频率信号可以为5GHz频段。The second wireless module 30 may include a second antenna 33 , a second radio frequency module 32 and a second baseband processing module 31 connected in sequence. The second wireless module 30 may establish a second frequency channel with the dual-band wireless router 40, and the second frequency signal in the second frequency channel may be a 5GHz frequency band.

可以理解的是,在第一无线模块20中,存在有接收通路和发送通路。在接收通路中,第一天线23可以从路由器接收第一频率信号并发送给第一射频模块22,第一射频模块22对该第一频率信号进行低噪放大和滤波后,可以发送给第一基带处理模块21,第一基带处理模块21可以将该第一频率信号转换为智能终端可识别的数据信号并发送给主控芯片10,例如显示信号、音频信号等。而在发射通路中,第一基带处理模块21可以接收主控芯片10发出的数据信号,并将该数据信号转换为第一频率信号发送给第一射频模块22,第一射频模块22在对该第一频率信号进行功率放大和滤波后,即可通过第一天线23将该信号发送给路由器。即,主控芯片10可以通过第一无线模块20中的接收通路和发射通路实现与双频无线路由器40在第一频率信道上进行信号传输。It can be understood that, in the first wireless module 20, there are a receiving path and a sending path. In the receiving path, the first antenna 23 can receive the first frequency signal from the router and send it to the first radio frequency module 22. After the first radio frequency module 22 performs low noise amplification and filtering on the first frequency signal, it can send it to the first radio frequency module 22. The baseband processing module 21, the first baseband processing module 21 can convert the first frequency signal into a data signal identifiable by the smart terminal and send it to the main control chip 10, such as a display signal, an audio signal, and the like. In the transmission path, the first baseband processing module 21 can receive the data signal sent by the main control chip 10, convert the data signal into a first frequency signal and send it to the first radio frequency module 22. After the first frequency signal is power amplified and filtered, the signal can be sent to the router through the first antenna 23 . That is, the main control chip 10 can implement signal transmission with the dual-frequency wireless router 40 on the first frequency channel through the receiving channel and the transmitting channel in the first wireless module 20 .

同样地,主控芯片10还可以通过第二无线模块30中的接收通路和发射通路实现与双频无线路由器40在第二频率信道上进行信号传输。其中,第一频率信道即为2.4GHz频段,第二频率信道即为5GHz频段。主控芯片10可以通过启动两个无线模块,对同一双频无线路由器40的两个频段进行搜索,并接入双频无线路由器40的局域网络。在双频无线路由器40可提供足够带宽时,若第一无线模块20和第二无线模块30中的天线对应的无线传输协议分别为802.11n+2.4G 300Mbps、802.11n+5G 300Mbps,则主控芯片10可以在采用双频并发连接通过两个无线模块实现600Mbps带宽的网络连接速度。并且在双频并发时,还能够大大降低网络延时,提升用户的使用体验。Similarly, the main control chip 10 can also implement signal transmission with the dual-frequency wireless router 40 on the second frequency channel through the receiving channel and the transmitting channel in the second wireless module 30 . The first frequency channel is the 2.4GHz frequency band, and the second frequency channel is the 5GHz frequency band. The main control chip 10 can search the two frequency bands of the same dual-band wireless router 40 by starting the two wireless modules, and access the local area network of the dual-band 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 respectively, then the master The chip 10 can achieve a network connection speed of 600 Mbps bandwidth through two wireless modules using dual-band concurrent connections. And in the case of dual-frequency concurrent, it can also greatly reduce the network delay and improve the user experience.

需要说明的是,第一无线模块20和第二无线模块30分别接入两个不同的基带处理模块,并通过无线数据接口与主控芯片10连接,因此主控芯片10能够同时通过两个无线模块实现网络通讯,主控芯片10上还设置有软件私有协议,能够将两路无线模块输入的数据信号进行汇聚处理。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 are connected to the main control chip 10 through a wireless data interface, so the main control chip 10 can simultaneously pass two wireless The module realizes network communication, and the main control chip 10 is also provided with a software proprietary protocol, which can aggregate and process the data signals input by the two wireless modules.

进一步地,主控芯片10在通过两个无线模块与路由器连接时,还可以对第一频率信号和第二频率信号的信号强度分别进行检测。在某一频率信道的干扰比较严重时,该频率信号对应的信号强度将会显著降低。通过对信号强度进行检测,可以从两个频率信道中确定出信号传输质量更好的频段,并选择该频率信道作为主信道。可以理解的是,在主控芯片10检测并确定两个频率信道的信号强度均高于预设强度阈值时,可以分别通过两路频率信道实现双频并发通信。即,在两路频率信道中的某一路在干扰较大而无法正常进行通讯时,能够自动切换至另一干扰较小的频率信道实现信号通讯,无需用户进行手动调整,提升了用户的通讯体验。Further, when the main control chip 10 is connected to the router through two wireless modules, the signal strengths of the first frequency signal and the second frequency signal can also be detected respectively. When the interference of a certain frequency channel is serious, 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 this frequency channel is selected as the main channel. It can be understood that when the main control chip 10 detects and determines that the signal strengths of the two frequency channels are both higher than the preset strength threshold, dual-frequency concurrent communication can be implemented through the two frequency channels respectively. That is, when one of the two frequency channels has large interference and cannot communicate normally, it can automatically switch to another frequency channel with less interference to realize signal communication, without the need for manual adjustment by the user, which improves the user's communication experience. .

本发明还提供一种智能终端,该智能终端包括与单相市电连接的开关电源以及控制所述开关电源接通或关断的双频并发通讯电路,该双频并发通讯电路的结构可参照上述实施例,在此不再赘述。理所应当地,由于本实施例的智能终端采用了上述双频并发通讯电路的技术方案,因此该智能终端具有上述双频并发通讯电路所有的有益效果。The present invention also provides an intelligent terminal, which includes a switching power supply connected to the single-phase mains and a dual-frequency concurrent communication circuit that controls the switching power supply to be turned on or off.

As a matter of course, since the intelligent terminal of this embodiment adopts the technical solution of the above-mentioned dual-frequency concurrent communication circuit, the intelligent terminal has all the beneficial effects of the above-mentioned dual-frequency concurrent communication circuit.

本发明应用于电视的具体实施例与下述应用双频信号选择方法的各个实施例基本相同,在此不作赘述。The specific embodiments of the present invention applied to the television are basically the same as the following embodiments of the application of the dual-frequency signal selection method, and will not be repeated here.

请参照图2,图2为本发明双频信号选择方法第一实施例的流程示意图,其中,所述双频信号选择方法包括如下步骤:Please refer to FIG. 2 , which is a schematic flowchart of a first embodiment of a dual-frequency signal selection method according to the present invention, wherein the dual-frequency signal selection method includes the following steps:

步骤S10,检测第一频率信道和第二频率信道的信号强度;Step S10, detecting the signal strength of the first frequency channel and the second frequency channel;

本实施例终端可以为能够与无线路由器进行网络连接的智能终端,以下以电视为例进行说明。电视包括主控芯片、第一无线模块和第二无线模块。其中,第一无线模块和第二无线模块分别与主控芯片连接,在双频无线路由器提供两个频段的连接信道时,主控芯片可以分别通过第一无线模块和第二无线模块与双频无线路由器的两个信道进行连接,以实现双频并发通讯。可以理解的是,第一无线模块和第二无线模块可以通过USB接口与主控芯片连接,并通过设置在无线模块上的天线与双频无线路由器通讯连接。The terminal in this embodiment may be an intelligent terminal capable of performing network connection with a wireless router, and a TV is used as an example for description below. The TV includes 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 to the main control chip. When the dual-band wireless router provides connection channels of two frequency bands, the main control chip can communicate with the dual-band through the first wireless module and the second wireless module, respectively. The two channels of the wireless router are connected to achieve dual-band concurrent communication. It can be understood that the first wireless module and the second wireless module can be connected to the main control chip through a USB interface, and communicated with the dual-band wireless router through an antenna disposed on the wireless module.

在主控芯片通过第一无线模块和第二无线模块分别接入双频无线路由器的第一频率信道和第二频率信道时,可以对两路信道中的信号强度分别进行检测。When the main control chip is respectively connected to the first frequency channel and the second frequency channel of the dual-band wireless router through the first wireless module and the second wireless module, the signal strengths in the two channels can be detected respectively.

步骤S20,所述信号强度从所述第一频率信道和所述第二频率信道中选择主信道通路。Step S20, the signal strength selects a main channel path from the first frequency channel and the second frequency channel.

主控芯片通过检测两个频率信道的信号强度,能够从两路信道中优先选择信号传输质量较好的信道实现通讯。即,在主控芯片检测到两路信道中的其中一路信道的信号强度不足以实现数据通讯时,可以将该路信道进行关闭,并通过另一路信道作为主信道通路实现数据通讯。By detecting the signal strength of the two frequency channels, the main control chip can preferentially select the channel with better signal transmission quality from the two channels to realize communication. That is, when the main control chip detects that the signal strength of one of the two channels is insufficient for data communication, the channel can be closed, and the other channel can be used as the main channel to realize data communication.

进一步的,在本发明双频信号选择方法第二实施例中,基于上述图2所示的实施例,所述步骤S10,检测第一频率信道和第二频率信道的信号强度的步骤包括:Further, in the second embodiment of the dual-frequency signal selection method of the present invention, based on the embodiment shown in FIG. 2 above, in step S10, the step of detecting the signal strengths of the first frequency channel and the second frequency channel includes:

步骤S11,根据第一无线模块发送的第一频率信号计算第一频率信道对应的第一信号强度;Step S11, calculating the first signal strength corresponding to the first frequency channel according to the first frequency signal sent by the first wireless module;

步骤S12,根据第二无线模块发送的第二频率信号计算第二频率信道对应的第二信号强度。Step S12: Calculate the second signal strength corresponding to the second frequency channel according to the second frequency signal sent by the second wireless module.

在本实施例中,主控芯片在通过第一无线模块与双频无线路由器的第一频率信道实现数据通讯时,可以通过第一无线模块发送的第一频率信号计算得到相应的信号强度RSSI,即第一信号强度。同样地,主控芯片还可以根据第二频率信号计算得到第二频率信号所对应的第二信号强度。主控芯片在计算得到第一信号强度和第二信号强度时,即可根据第一信号强度和第二信号强度的强度大小从第一频率信道和第二频率信道中选择主信道通路。In this embodiment, when the main control chip realizes data communication through the first wireless module and the first frequency channel of the dual-band wireless router, the corresponding signal strength RSSI can be obtained by calculating the first frequency signal sent by the first wireless module, That is, the first signal strength. Similarly, the main control chip may also calculate and obtain the 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, it can select the main channel path from the first frequency channel and the second frequency channel according to the strength of the first signal strength and the second signal strength.

进一步的,参照图3,图3为本发明双频信号选择方法第三实施例的流程示意图,基于上述图2所示的实施例,所述步骤S20,所述信号强度从所述第一频率信道和所述第二频率信道中选择主信道通路的步骤包括:Further, referring to FIG. 3, FIG. 3 is a schematic flowchart of the third embodiment of the dual-frequency signal selection method according to the present invention. Based on the embodiment shown in FIG. 2 above, in step S20, the signal strength is determined from the first frequency The step of selecting a primary channel path in the channel and the second frequency channel includes:

步骤S21,将所述第一信号强度、所述第二信号强度分别与信号强度阈值进行比较;Step S21, comparing the first signal strength and the second signal strength with a signal strength threshold respectively;

步骤S22,在所述第一信号强度低于信号强度阈值时,控制第一频率信道关闭;Step S22, when the first signal strength is lower than the signal strength threshold, controlling the first frequency channel to be closed;

步骤S23,在所述第二信号强度低于信号强度阈值时,控制第二频率信道关闭。Step S23, when the second signal strength is lower than the signal strength threshold, control the second frequency channel to close.

在本实施例中,主控芯片内预先存储有信号强度阈值,在检测计算得到的信号强度大小低于信号强度阈值时,表示该信道内的干扰信号较强,容易影响到信号数据传输的稳定性和准确性。在主控芯片计算得到第一信号强度和第二信号强度时,可以将第一信号强度和第二信号强度分别与信号强度阈值进行比较,在第一信号强度低于信号强度阈值时,表示双频无线路由器的2.4GHz频段受到较强干扰信号的影响,已经不适合作为数据通讯的信道,此时主控芯片可以控制第一频率信道关闭,通过第二频率信道实现数据传输。同样地,在检测到第二信号强度低于信号强度阈值时,表示双频无线路由器的5GHz频段受到较强干扰信号的影响,已经不适合作为数据通讯的信道,此时主控芯片可以控制第二频率信道关闭,通过第一频率信道实现数据传输。可以理解的是,主控芯片通过实时监测两路信道所对应的信号强度,能够实现信号强度。In this embodiment, the signal strength threshold is pre-stored in the main control chip. When the signal strength obtained by detection and calculation is lower than the signal strength threshold, it means that the interference signal in the channel is strong, which easily affects the stability of signal data transmission. sex and accuracy. When the main control chip calculates and obtains the first signal strength and the second signal strength, the first signal strength and the second signal strength can be compared with the signal strength threshold respectively. When the first signal strength is lower than the signal strength threshold, it means that the double The 2.4GHz frequency band of the wireless router is affected by strong interference signals and is no longer suitable as a channel for data communication. At this time, the main control chip can control the first frequency channel to be closed, and realize data transmission through the second frequency channel. Similarly, when it is detected that the second signal strength is lower than the signal strength threshold, it means that the 5GHz frequency band of the dual-band wireless router is affected by strong interference signals and is no longer suitable as a channel for data communication. At this time, the main control chip can control the first The second frequency channel is closed, and data transmission is realized through the first frequency channel. It can be understood that the main control chip can realize the signal strength by monitoring the signal strength corresponding to the two channels in real time.

进一步的,继续参照图3,图3为本发明双频信号选择方法第四实施例的流程示意图,所述步骤S21,将所述第一信号强度、所述第二信号强度分别与信号强度阈值进行比较的步骤之后,还包括:Further, referring to FIG. 3, FIG. 3 is a schematic flowchart of the fourth embodiment of the dual-frequency signal selection method according to the present invention. In step S21, the first signal strength, the second signal strength and the signal strength threshold are respectively After the comparison steps, also include:

步骤S24,在所述第一信号强度和所述第二信号强度均高于信号强度阈值时,通过第一频率信道和第二频率信道进行双频信号传输。Step S24, when both the first signal strength and the second signal strength are higher than the signal strength threshold, perform dual-frequency signal transmission through the first frequency channel and the second frequency channel.

在本实施例中,主控芯片在确定第一信号强度和第二信号强度均高于信号强度阈值时,可以通过两个无线模块分别与双频无线路由器的两个频段实现通讯连接。即通过第一频率信道和第二频率信道进行双频信号传输。在双频信号传输过程中,主控芯片与路由器之间的实际带宽为两路信道的带宽之和,并且使用双数据汇聚还能够降低网络延时,提升网络传输效率。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 can communicate with the two frequency bands of the dual-band wireless router through two wireless modules respectively. That is, dual-frequency signal transmission is performed through the first frequency channel and the second frequency channel. In the process of dual-band signal transmission, the actual bandwidth between the main control chip and the router is the sum of the bandwidths of the two channels, and the use of dual-data aggregation can also reduce network latency and improve network transmission efficiency.

此外,本发明还提出一种计算机可读存储介质,其上存储有智能设备配网程序。所述计算机可读存储介质可以是如ROM(Read-Only Memory,只读存储器)/RAM(RandomAccess Memory,随机存取存储器)、磁碟、光盘中的至少一种,所述计算机可读存储介质包括若干指令用以使得一台具有主控芯片的智能终端执行本发明各个实施例所述的双频信号选择方法。In addition, the present invention also provides a computer-readable storage medium, on which a network configuration program of a smart device is stored.
