本发明涉及移动通信领域，具体涉及一种射频干扰消除方法、装置、存储介质和终端。The present invention relates to the field of mobile communication, in particular to a radio frequency interference elimination method, device, storage medium and terminal.
背景技术Background technique
随着终端技术的发展，移动终端已经开始从以前简单地提供通话设备渐渐变成一个通用软件运行的平台。该平台不再以提供通话管理为主要目的，而是提供一个包括通话管理、游戏娱乐、办公记事、移动支付等各类应用软件在内的运行环境，随着大量的普及，已经深入至人们的生活、工作的方方面面。With the development of terminal technology, the mobile terminal has gradually changed from simply providing communication equipment to a platform for general software operation. The platform no longer aims to provide call management, but to provide an operating environment including call management, game entertainment, office notes, mobile payment and other application software. With a large number of popularization, it has penetrated into people's All aspects of life and work.
终端的信号强弱，影响了终端的通话质量、网速快慢以及耗电量等等。其中，终端的信号强弱一方面取决于运营商的网络，一方面取决于终端本身，运营商的网络覆盖目前主要是跟基站的布局和发射功率有关，现有终端通常采用内置天线，内置天线容易受到干扰，这其中既包括射频系统内部之间的干扰，也包含有其他系统对射频通信的干扰。例如智能终端系统中的马达系统、摄像系统、指纹系统等等。这些干扰都会导致当前使用信道信号质量变差，从而造成通话质量变差或是掉线情况。The signal strength of the terminal affects the call quality, network speed and power consumption of the terminal. Among them, the signal strength of the terminal depends on the operator's network on the one hand, and on the terminal itself on the other hand. The network coverage of the operator is mainly related to the layout and transmission power of the base station. The existing terminal usually uses a built-in antenna, and the built-in antenna Susceptible to interference, which includes both internal interference within the radio frequency system and interference from other systems to radio frequency communications. For example, the motor system, camera system, fingerprint system and so on in the intelligent terminal system. All these interferences will cause the signal quality of the currently used channel to deteriorate, resulting in poor call quality or dropped calls.
由上可知，现有技术中的终端会受到内部射频系统的干扰，从而使终端的信号强度变弱。It can be seen from the above that the terminal in the prior art will be interfered by the internal radio frequency system, so that the signal strength of the terminal will be weakened.

请参阅图1，图1为本发明实施例提供的一种射频干扰消除方法的流程示意图，本实施例的射频干扰消除方法包括：Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for eliminating radio frequency interference provided by an embodiment of the present invention. The method for eliminating radio frequency interference in this embodiment includes:
步骤S101，获取终端接收射频信号的信号强度值。Step S101, acquiring a signal strength value of a radio frequency signal received by a terminal.
在本发明实施例当中，终端接收基站发送的信号以完成通讯功能，上述基站可以是基于无线保真WIFI(Wireless Fidelity)标准的无线局域网LAN(Local Area Network)的基站，可以是全球移动通信系统GSM(Global System for Mobile Communication)的基站，或者可以是蓝牙的基站。终端基于该基站控制的无线通信，传送和接收各类数据。例如，终端可以经由基站从内容分发服务器接收内容数据，并且可以将电子邮件传送到另一终端和从另一终端接收电子邮件。其中，内容数据可包括诸如音乐、广播等音乐数据、如运动图片、电视节目、视频、照片等的视觉数据、以及诸如游戏、软件等的任何其它数据。In the embodiment of the present invention, the terminal receives the signal sent by the base station to complete the communication function. The above-mentioned base station may be a base station of a wireless local area network LAN (Local Area Network) based on the Wireless Fidelity WIFI (Wireless Fidelity) standard, and may be a global system for mobile communication A base station of GSM (Global System for Mobile Communication), or a base station of Bluetooth. The terminal transmits and receives various types of data based on wireless communication controlled by the base station. For example, a terminal may receive content data from a content distribution server via a base station, and may transmit and receive electronic mail to and from another terminal. Among them, the content data may include musical data such as music, radio, etc., visual data such as motion pictures, TV programs, videos, photos, etc., and any other data such as games, software, etc.
基站的主要功能就是提供无线覆盖，即实现有线通信网络与无线终端之间的无线信号传输。所以基站在通信网络中的位置如图2所示，核心网侧的控制信令、语音呼叫或数据业务信息通过传输网络发送到基站(在2G、3G网络中，信号先传送到基站控制器，再传送到基站)，信号在基站侧经过基带和射频处理，然后通过射频馈线送到天线上进行发射，终端通过无线信道接收天线所发射的无线电波，然后解调出属于自己的信号。The main function of the base station is to provide wireless coverage, that is, to realize wireless signal transmission between the wired communication network and the wireless terminal. Therefore, the position of the base station in the communication network is shown in Figure 2. The control signaling, voice call or data service information on the core network side is sent to the base station through the transmission network (in 2G and 3G networks, the signal is first transmitted to the base station controller, Then transmitted to the base station), the signal is processed by baseband and radio frequency on the base station side, and then sent to the antenna for transmission through the radio frequency feeder, the terminal receives the radio wave transmitted by the antenna through the wireless channel, and then demodulates its own signal.
在终端接收到从基站传送的射频信号时，终端测量射频信号的信号强度值。其中，终端测量射频信号的信号强度值的方式可以有多种，比如向moden(调制解调器)查询当前终端的信号参数信息，该参数信息包括射频信号的信号强度值，当然，上述信号参数信息还可以包括网络制式、频段、信道等信息。When the terminal receives the radio frequency signal transmitted from the base station, the terminal measures the signal strength value of the radio frequency signal. Among them, there are many ways for the terminal to measure the signal strength value of the radio frequency signal. For example, query the signal parameter information of the current terminal to the moden (modem), and the parameter information includes the signal strength value of the radio frequency signal. Of course, the above signal parameter information can also be Including network standard, frequency band, channel and other information.
在本发明实施例当中，在终端接收到射频信号后，还需要经功率分配器对其进行分配，其中，该功率分配器是一种可以将一路输入信号能量分成两路或多路输出相等或不相等能量的器件，分配后即得到一个最终的射频信号。In the embodiment of the present invention, after the terminal receives the radio frequency signal, it needs to be distributed through the power divider. Devices with unequal energy will get a final RF signal after distribution.
步骤S102，当信号强度值小于预设信号强度值时，确定终端当中处于工作状态的目标器件。Step S102, when the signal strength value is less than the preset signal strength value, determine the target device in the working state among the terminals.
在本发明实施例中，可以预先设置一个预设信号强度值，可以理解的是，当射频信号的信号强度值低于该预设信号强度值的时候，说明终端中存在干扰信号，也即存在干扰源。这会对终端造成信号差、通话中断、通话质量差、无法接通等等问题，此时需要在终端中找到上述干扰源。当射频信号的信号强度值高于或等于该预设信号强度值时，则确定终端当前未受到干扰信号的影响，结束当前流程即可。In the embodiment of the present invention, a preset signal strength value may be preset. It can be understood that when the signal strength value of the radio frequency signal is lower than the preset signal strength value, it means that there is an interference signal in the terminal, that is, there is a source of interference. This will cause problems such as poor signal, call interruption, poor call quality, and failure to connect to the terminal. At this time, it is necessary to find the above-mentioned interference sources in the terminal. When the signal strength value of the radio frequency signal is higher than or equal to the preset signal strength value, it is determined that the terminal is not currently affected by the interference signal, and the current process can be ended.
进一步的，确定终端中当前处于工作状态的目标器件的方法可以有多种。比如预先确定终端当中工作时能对终端信号造成干扰的器件，比如摄像头、显示屏、闪光灯等器件，以得到一个集合，然后分别判断该集合中的器件当前是否处于工作状态，若处于，则确定该器件为目标器件。Further, there may be multiple methods for determining the target device that is currently working in the terminal. For example, predetermine the devices that can interfere with the terminal signal when working in the terminal, such as cameras, display screens, flashlights and other devices, to obtain a set, and then judge whether the devices in the set are currently working, and if they are, then determine This device is the target device.
在其他实施例中，还可以获取终端中全部处于工作状态的器件，以得到一个集合，考虑到并不是终端中所有工作的器件都能够干扰到终端的信号强度，所以需要进一步在该集合当中确定目标器件，比如，分别判断该集合当中的器件是否能产生干扰信号，若是，则确定该器件为目标器件。In other embodiments, it is also possible to acquire all the devices in the working state in the terminal to obtain a set. Considering that not all the working devices in the terminal can interfere with the signal strength of the terminal, it is necessary to further determine in the set The target device, for example, judges whether the devices in the set can generate interference signals, and if so, determines that the device is the target device.
步骤S103，获取目标器件对应的干扰信号强度值，并根据干扰信号强度值生成负相位信号。Step S103, acquiring an interference signal strength value corresponding to the target device, and generating a negative phase signal according to the interference signal strength value.
在确定目标器件之后，根据目标器件获取对应的干扰信号强度值，在本发明实施例当中，可以预先设置多个预设器件以及该器件对应的干扰信号强度值，比如，预先建立关于终端中预设器件的干扰信号数据库，其中干扰信号数据库包括多个预设器件以及预设器件对应的干扰信号强度值。在确定目标器件后，判断上述多个预设器件当中是否存在与目标器件相同的器件，若存在，则获取该预设器件对应的干扰信号强度值，并根据该干扰信号强度值生成负相位信号。After the target device is determined, the corresponding interference signal strength value is obtained according to the target device. In the embodiment of the present invention, multiple preset devices and the corresponding interference signal strength value of the device can be preset. An interference signal database of devices is provided, wherein the interference signal database includes a plurality of preset devices and interference signal strength values corresponding to the preset devices. After determining the target device, judge whether there is a device identical to the target device among the above-mentioned multiple preset devices, and if so, obtain the interference signal strength value corresponding to the preset device, and generate a negative phase signal according to the interference signal strength value .
步骤S104，将射频信号和负相位信号进行合路，以消除目标器件对应的干扰。Step S104, combine the radio frequency signal and the negative phase signal to eliminate the interference corresponding to the target device.
在本发明实施例中，射频信号当中包含有用信号和干扰信号，将射频信号与负相位信号进行合路，比如通过合路器，可以将输入的多频段的信号组合到一起输出，以消除目标器件对应的干扰，得到射频信号中的有用信号。In the embodiment of the present invention, the radio frequency signal contains useful signals and interference signals, and the radio frequency signal and the negative phase signal are combined. For example, through a combiner, the input multi-band signals can be combined and output together to eliminate the target signal. The interference corresponding to the device can be used to obtain the useful signal in the radio frequency signal.
可以理解的是，本发明实施例中的目标器件可以为一个也可以为多个，故而上述负相位信号也可以为一个或多个。比如，当目标器件为一个时，即生成一个负相位信号，上述合路器可以为双频合路器；当目标器件为两个时，即生成两个负相位信号，此时上述合路器可以为三频合路器，以此类推。It can be understood that, in the embodiment of the present invention, there may be one or more target devices, and therefore the foregoing negative phase signals may also be one or more. For example, when there is one target device, a negative-phase signal is generated, and the above-mentioned combiner can be a dual-frequency combiner; when there are two target devices, two negative-phase signals are generated, and the above-mentioned combiner It can be a three-frequency combiner, and so on.
如图3所示，图3为本发明实施例提供的射频干扰消除方法的一种应用示意图。在本发明实施例中，射频信号首先进入功率分配器21，从而得到一个实际接收的射频信号，获取其信号强度值，并于预先设置的预设信号强度值在比较模块23当中进行比较，当判断信号强度值小于预设信号强度值时，处理器24发送开关信号至负相位频率合成器25，且上述处理器24判断具体是哪个模块产生干扰，以便生成控制信号至负相位频率合成器25，负相位频率合成器25以晶振信号生成基准频率信号，并根据上述干扰源的干扰信号强度生成负相位信号，最后发送至合路器22，由合路器22对上述射频信号和负相位信号进行合路，以消除目标器件对应的干扰。As shown in FIG. 3 , FIG. 3 is a schematic diagram of an application of the method for eliminating radio frequency interference provided by an embodiment of the present invention. In the embodiment of the present invention, the radio frequency signal first enters the power divider 21 to obtain an actually received radio frequency signal, obtain its signal strength value, and compare it with the preset preset signal strength value in the comparison module 23, when When it is judged that the signal strength value is less than the preset signal strength value, the processor 24 sends a switch signal to the negative phase frequency synthesizer 25, and the processor 24 judges which module specifically generates interference, so as to generate a control signal to the negative phase frequency synthesizer 25 , the negative phase frequency synthesizer 25 generates the reference frequency signal with the crystal oscillator signal, and generates a negative phase signal according to the interference signal strength of the above-mentioned interference source, and finally sends it to the combiner 22, and the above-mentioned radio frequency signal and the negative phase signal are compared by the combiner 22 Combination is performed to eliminate the interference corresponding to the target device.
由上可知，本发明实施例可以获取终端接收射频信号的信号强度值，当信号强度值小于预设信号强度值时，确定终端当中处于工作状态的目标器件，获取目标器件对应的干扰信号强度值，并根据干扰信号强度值生成负相位信号，将射频信号和负相位信号进行合路，以消除所述目标器件对应的干扰。本发明可以在终端收到内部器件干扰时，确定生成干扰信号的目标器件，并获取对应的负相位信号，通过将负相位信号与射频信号合路，以消除干扰信号，从而可以提升终端的射频信号强度。It can be seen from the above that the embodiment of the present invention can obtain the signal strength value of the radio frequency signal received by the terminal, and when the signal strength value is less than the preset signal strength value, determine the target device in the working state in the terminal, and obtain the interference signal strength value corresponding to the target device , and generate a negative phase signal according to the interference signal strength value, and combine the radio frequency signal and the negative phase signal to eliminate the interference corresponding to the target device. The present invention can determine the target device that generates the interference signal when the terminal receives interference from the internal device, and obtain the corresponding negative phase signal, and eliminate the interference signal by combining the negative phase signal with the radio frequency signal, thereby improving the radio frequency of the terminal signal strength.
根据上一实施例的描述，以下将进一步来说明本发明的射频干扰消除方法。According to the description of the previous embodiment, the radio frequency interference elimination method of the present invention will be further described below.
请参阅图4，图4为本发明实施例提供的另一种射频干扰消除方法的流程示意图，包括：Please refer to FIG. 4. FIG. 4 is a schematic flowchart of another radio frequency interference elimination method provided by an embodiment of the present invention, including:
步骤S201，检测终端中每个器件开启前终端的第一信号强度值，和关闭后的第二信号强度值。Step S201, detecting the first signal strength value of each device in the terminal before it is turned on, and the second signal strength value after it is turned off.
比如，在手机当中，分别在手机中的各个工作模块开启前及开启后的状态下，对射频收发器接收到的射频信号进行检测。需要说明的是，每次测试开启状态的射频信号时，仅开启该待测试的工作模块，以保证测试结果不会受到其他工作模块的影响。其中，上述工作模块比如为摄像头、扬声器、指纹识别模块等等。For example, in a mobile phone, the radio frequency signal received by the radio frequency transceiver is detected before and after each working module in the mobile phone is turned on. It should be noted that, each time the radio frequency signal in the turned-on state is tested, only the working module to be tested is turned on, so as to ensure that the test result will not be affected by other working modules. Wherein, the above-mentioned working modules are, for example, a camera, a speaker, a fingerprint identification module and the like.
步骤S202，若第一信号强度值和第二信号强度值不同，则确定该器件为预设器件，且确定第一信号强度值和第二信号强度值之间的差值为干扰信号强度值。Step S202, if the first signal strength value and the second signal strength value are different, then determine that the device is a default device, and determine the difference between the first signal strength value and the second signal strength value as the interference signal strength value.
在本实施例当中，若无任何信号干扰，则工作模块开启前与开启后，射频收发器接收到的第一射频信号与第二射频信号的波形和幅度应该是无差异的。因此，当第一信号强度值和第二信号强度值不同时，说明当前存在信号干扰，确定该器件为预设器件，也即干扰源。进一步的，确定第一信号强度值和第二信号强度值之间的差值为干扰信号强度值。In this embodiment, if there is no signal interference, the waveforms and amplitudes of the first radio frequency signal and the second radio frequency signal received by the radio frequency transceiver should be the same before and after the working module is turned on. Therefore, when the first signal strength value is different from the second signal strength value, it means that there is signal interference at present, and the device is determined to be a preset device, that is, an interference source. Further, it is determined that the difference between the first signal strength value and the second signal strength value is the interference signal strength value.
步骤S203，根据预设器件和预设器件对应的干扰信号强度值建立干扰信号数据库。Step S203, establishing an interference signal database according to the preset device and the interference signal strength value corresponding to the preset device.
可以理解的是，通过逐一测试，确认终端中所存在的影响射频信号的干扰模块，并根据计算到的差值生成对应的干扰信号强度值，再将该干扰模块、以及该干扰模块对应的干扰信号强度值存储到相应位置，以生成干扰信号数据库。It can be understood that, by testing one by one, confirm the interference module that affects the radio frequency signal in the terminal, and generate the corresponding interference signal strength value according to the calculated difference, and then use the interference module and the interference module corresponding to the interference module The signal strength values are stored in place to generate a database of interfering signals.
步骤S204，获取终端接收射频信号的信号强度值。Step S204, acquiring the signal strength value of the radio frequency signal received by the terminal.
在终端接收到从基站传送的射频信号时，终端测量射频信号的信号强度值。其中，终端测量射频信号的信号强度值的方式可以有多种，比如向moden(调制解调器)查询当前终端的信号参数信息，该参数信息包括射频信号的信号强度值，当然，上述信号参数信息还可以包括网络制式、频段、信道等信息。When the terminal receives the radio frequency signal transmitted from the base station, the terminal measures the signal strength value of the radio frequency signal. Among them, there are many ways for the terminal to measure the signal strength value of the radio frequency signal. For example, query the signal parameter information of the current terminal to the moden (modem), and the parameter information includes the signal strength value of the radio frequency signal. Of course, the above signal parameter information can also be Including network standard, frequency band, channel and other information.
步骤S205，判断信号强度值是否小于预设信号强度值，若是，则执行步骤S206，若否，则结束流程。Step S205, judging whether the signal strength value is smaller than a preset signal strength value, if yes, execute step S206, if not, end the process.
在本发明实施例中，可以预先设置一个预设信号强度值，可以理解的是，当射频信号的信号强度值低于该预设信号强度值的时候，说明终端中存在干扰信号，也即存在干扰源。此时需要在终端中找到上述干扰源，可以进一步执行步骤S206。In the embodiment of the present invention, a preset signal strength value can be preset. It can be understood that when the signal strength value of the radio frequency signal is lower than the preset signal strength value, it means that there is an interference signal in the terminal, that is, there is a source of interference. At this time, it is necessary to find the above-mentioned interference source in the terminal, and step S206 may be further performed.
步骤S206，确定终端当中处于工作状态的目标器件。Step S206, determining the target device in the working state among the terminals.
比如预先确定终端当中工作时能对终端信号造成干扰的器件，比如摄像头、显示屏、闪光灯等器件，以得到一个集合，然后分别判断该集合中的器件当前是否处于工作状态，若处于，则确定该器件为目标器件。For example, predetermine the devices that can interfere with the terminal signal when working in the terminal, such as cameras, display screens, flashlights and other devices, to obtain a set, and then judge whether the devices in the set are currently working, and if they are, then determine This device is the target device.

If the first signal strength value and the second signal strength value are different, then Determine that the device is a preset device, and determine that the difference between the first signal strength value and the second signal strength value is an interference signal strength value, and establish an interference signal database according to the interference signal strength value corresponding to the preset device and the preset device , to obtain the signal strength value of the radio frequency signal received by the terminal, and judge whether the signal strength value is less than the preset signal strength value.
