下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
在智能手机中，一般都包括两个天线，分别为第一天线和第二天线，也可理解主集天线和分集天线，通过两个天线接收外界的信号，但是当主集天线收到干扰时，手机并不会将主集天线切换到分集天线接收信号，为了解决该问题，本发明实施例提供了一种天线切换方法及装置，该方法通过实时检测手机中的两个天线的性能指标，具体为接收灵敏度，并将两天线的接收灵敏度进行相互比较，根据比较的结果判断是否需要进行天线的切换，若需要切换，则将手机当前用于接收信号的第一天线切换至与第二天线连接，通过第二天线继续接收外界的信号，从而实现手机在任何场景下受到干扰时，都可以保持最佳的接收性能。In a smart phone, two antennas are generally included, which are a first antenna and a second antenna respectively. It is also understood that the main antenna and the diversity antenna receive external signals through two antennas, but when the main antenna receives interference, The mobile phone does not switch the main set antenna to the diversity antenna to receive the signal. To solve the problem, the embodiment of the present invention provides an antenna switching method and device, which detects the performance indexes of the two antennas in the mobile phone in real time, specifically In order to receive the sensitivity, and compare the receiving sensitivities of the two antennas, it is determined according to the result of the comparison whether the antenna needs to be switched. If the switching is required, the first antenna currently used by the mobile phone to receive the signal is switched to be connected to the second antenna. The second antenna continues to receive signals from the outside world, so that the mobile phone can maintain optimal reception performance when it is interfered in any scene.
第一实施例：First embodiment:
请参见图1，图1为本发明实施例提供的天线切换方法的流程图。在本实施例中，该天线切换方法的具体包括如下步骤：Referring to FIG. 1, FIG. 1 is a flowchart of an antenna switching method according to an embodiment of the present invention. In this embodiment, the antenna switching method specifically includes the following steps:
S102，在终端上设置第一天线和第二天线。S102. Set a first antenna and a second antenna on the terminal.
在该步骤中，在为终端设置天线时，以第一天线作为第一工作状态下的工作天线，第二天线为备用天线用于在第二工作状态下接收信号，并且该工作天线具体设置为全向天线，这里的第一工作状态指的是终端的第一天线在不受到干扰时，通过第一天线接收外界信号的状态；当终端处于第 二工作态时，终端可以切换至第二天线接收信号，并且该第二天线可以设置为定向天线，这里的第二工作状态指的是终端处于受干扰场景下接收信号的状态。In this step, when the antenna is set for the terminal, the first antenna is used as the working antenna in the first working state, and the second antenna is the standby antenna for receiving the signal in the second working state, and the working antenna is specifically set to An omnidirectional antenna, where the first working state refers to a state in which the first antenna of the terminal receives an external signal through the first antenna when it is not interfered; when the terminal is in the first In the two working states, the terminal can switch to the second antenna to receive the signal, and the second antenna can be set as the directional antenna, where the second working state refers to the state in which the terminal is in the interfered scene to receive the signal.
S104，检测第一天线和第二天线的各性能指标，具体的该性能指标为天线对信号的接收灵敏度。S104. Detect various performance indicators of the first antenna and the second antenna. The specific performance indicator is a receiving sensitivity of the antenna to the signal.
在该步骤中，具体的是通过ASDIV技术对第一天线和第二天线实时接收信号的灵敏度进行检测，通过检测两天线对信号的接收灵敏度来判断天线是否受到干扰，进一步的，由于通过ASDIV技术可以在任何场景下都可以实现对天线接收灵敏度的检测，因为ASDIV技术可以在金属封闭的环境下也可以接收信号。In this step, specifically, the sensitivity of the first antenna and the second antenna to receive signals in real time is detected by the ASDIV technique, and the antenna is judged to be interfered by detecting the receiving sensitivity of the signals of the two antennas. Further, due to the ASDIV technology. The detection sensitivity of the antenna can be detected in any scene, because the ASDIV technology can also receive signals in a metal-enclosed environment.
在本实施例中，除了检测接收灵敏度这一性能参数来反映天线是否受干扰之外，还可以通过检测两天线接收到的信号强度来判断，当接收到的信号小强度比发射的信号轻度不一样时，则说明天线受到了干扰，进一步的，还可以是通过检测两个天线接收到的信号的速率等性能参数进行判断等等，通过检测到的两个天线对信号的接收性能参数，确定工作天线和备用天线是否受到干扰，若是，则执行步骤S106。In this embodiment, in addition to detecting the performance parameter of the receiving sensitivity to reflect whether the antenna is interfered, it can also be judged by detecting the signal strength received by the two antennas, when the received signal is less intense than the transmitted signal. When the difference is different, it indicates that the antenna is interfered. Further, it may be determined by detecting performance parameters such as the rate of the signals received by the two antennas, etc., and the received performance parameters of the signals by the two antennas are detected. It is determined whether the working antenna and the standby antenna are interfered, and if yes, step S106 is performed.
为了提高对天线性能参数检测的精确度，本实施例还提供了进行多次检测去平均值的方式进行检测，具体的预先设置一个时间段，通过在预设的时间段内同时对两个天线进行实时的检测，通过多次检测得到多个接收灵敏度后，根据多次检测到的接收灵敏度分别进行平均值的计算，最后通过计算得到的平均值判断是否天线受到干扰。In order to improve the accuracy of the detection of the performance parameters of the antenna, the embodiment further provides a method for performing a plurality of detection and de-averaging methods, and specifically sets a time period in advance, by simultaneously aligning two antennas in a preset time period. Real-time detection is performed. After receiving multiple sensing sensitivities by multiple detections, the average value is calculated based on the received sensitivities detected multiple times. Finally, the calculated average value is used to determine whether the antenna is interfered.
S106，判断所述各性能指标是否满足预设的切换条件。S106. Determine whether the performance indicators meet preset switching conditions.
在该步骤中，判断是否满足预设的切换条件，具体为通过将检测到的第一天线对信号的接收灵敏度与所述第二天线对信号的接收灵敏度相互进行比较，根据比较结果判断是否满足切换条件，当比较结果为第一天线的接收灵敏度小于第二天线，则说明满足切换条件，执行步骤S108，若大于，则不满足，返回步骤S104。 In this step, it is determined whether the preset switching condition is met, specifically, by comparing the received sensitivity of the detected first antenna pair signal with the receiving sensitivity of the second antenna pair signal, and determining whether the content is satisfied according to the comparison result. The switching condition, when the comparison result is that the receiving sensitivity of the first antenna is smaller than the second antenna, it indicates that the switching condition is satisfied, and step S108 is performed. If it is greater than, the processing is not satisfied, and the process returns to step S104.
在本实施例中，判断是否满足预设的切换条件，具体的还可以是判断备用天线的接收灵敏度与工作天线的接收灵敏度的差值是否大于预设值，若该差值大于预设值，则满足切换条件，执行步骤S108，若小于，则不满足，返回步骤S104。In this embodiment, it is determined whether the preset switching condition is met, and specifically whether the difference between the receiving sensitivity of the standby antenna and the receiving sensitivity of the working antenna is greater than a preset value, and if the difference is greater than a preset value, Then, the switching condition is satisfied, step S108 is performed, and if it is less than, it is not satisfied, and the process returns to step S104.
S108，若所述各性能指标满足切换条件，则所述终端从第一工作状态切换至第二工作状态，所述第二工作状态为所述终端通过第二天线接收信号。S108. If the performance indicators meet the handover condition, the terminal switches from the first working state to the second working state, where the second working state is that the terminal receives the signal by using the second antenna.
在该步骤中，具体的是根据步骤S106中的判断接收进行切换，当第一天线的接收灵敏度小于第二天线时，则将终端上当前用于接收信号的第一天线切换至与第二天线连接，通过第二天线继续接收信号，使得终端保持最佳的信号接收性能；若将第二天线的接收灵敏度与第一天线的接收灵敏度相减，得到一个差值，将该差值与预设值相比较，若该差值大于预设值，则将终端上当前用于接收信号的第一天线切换至与第二天线连接，通过第二天线继续接收信号。In this step, specifically, according to the judgment in step S106, the receiving is performed. When the receiving sensitivity of the first antenna is smaller than the second antenna, the first antenna currently used for receiving the signal on the terminal is switched to the second antenna. Connecting, continuing to receive signals through the second antenna, so that the terminal maintains optimal signal receiving performance; if the receiving sensitivity of the second antenna is subtracted from the receiving sensitivity of the first antenna, a difference is obtained, and the difference is preset Comparing the values, if the difference is greater than the preset value, the first antenna currently used for receiving the signal on the terminal is switched to be connected to the second antenna, and the signal is continuously received through the second antenna.
在本实施例中，具体的将第一天线设置为全向天线，第二天线为定向天线，为了提高在进行天线切换后，第二天线对信号的接收效率，还包括将第二天线设置于第一天线之上，并且使其方向与终端对信号无遮挡的方向一致，使得终端在切换与至第二天线连接后，利用定向天线具有较好的方向性增益的性能，使得终端更好地接收外界信号，这样既能避免人体对手机信号的影响，减小手机辐射SAR值，又能在同等输入功率条件下，方向性的聚集增益提高手机天线实际效率。对于定向天线的方向设置还可以根据用户在使用终端是的使用习惯来设置，从而避开了用户在使用时对天线的干扰。In this embodiment, the first antenna is specifically configured as an omnidirectional antenna, and the second antenna is a directional antenna. In order to improve the receiving efficiency of the second antenna after the antenna switching, the second antenna is further disposed on the antenna. Above the first antenna, and the direction thereof is consistent with the direction in which the terminal does not block the signal, so that the terminal has better directional gain performance by using the directional antenna after switching and connecting to the second antenna, so that the terminal is better. Receiving external signals, which can avoid the influence of the human body on the mobile phone signal, reduce the radiation SAR value of the mobile phone, and can increase the actual efficiency of the mobile phone antenna under the same input power condition. The direction setting of the directional antenna can also be set according to the usage habits of the user in the use terminal, thereby avoiding the interference of the user on the antenna during use.
具体的，在设置天线时，将所述定向天线和第一天线沿着终端的屏幕方向进行重叠设置，且所述定向天线设置于工作天线的上方，并将定向天线接收信号的方向设置与用户使用终端时的惯用抓取方向相反。优选地，在本实施例中，所述定向天线具体为分形天线。 Specifically, when the antenna is disposed, the directional antenna and the first antenna are overlapped along a screen direction of the terminal, and the directional antenna is disposed above the working antenna, and the direction of the directional antenna receiving the signal is set to the user. The usual gripping direction when using the terminal is reversed. Preferably, in this embodiment, the directional antenna is specifically a fractal antenna.
如图2所示，是以第一天线为全向天线，第二天线为分形天线的天线切换方法的具体处理流程图，其处理步骤如下：As shown in FIG. 2, the specific processing flowchart of the antenna switching method in which the first antenna is an omnidirectional antenna and the second antenna is a fractal antenna is as follows:
S202，开始。S202, start.
S204，全向天线和分形天线分别上报灵敏度。S204, the omnidirectional antenna and the fractal antenna respectively report the sensitivity.
S206，采样多次，计算平均值，具体的可以是通过设置采样时间点，或者设置采样时间段，在采样时间段内，不管采样多少次，只要检测到天线有上报就记录，直到采样时间到达为止，然后计算平均值，并将该平均值作为天线的接收灵敏度。S206, sampling a plurality of times, calculating an average value, specifically by setting a sampling time point, or setting a sampling time period, in the sampling time period, no matter how many times of sampling, as long as the detected antenna is reported, the recording is performed until the sampling time is reached. So far, the average value is calculated and used as the receiving sensitivity of the antenna.
在该步骤中，两个天线上报灵敏度值时，具体是每个960ms采样一次，一共采样分别4次，待4次采样完成后，将4次采样到的灵敏度值进行计算，得到一平均值，并将该平均值作为天线的接收灵敏度。In this step, when the two antennas report the sensitivity value, the sampling is performed once every 960 ms, and the total sampling is 4 times. After the 4 samples are completed, the sensitivity values of the 4 samples are calculated to obtain an average value. This average value is taken as the receiving sensitivity of the antenna.
S208，比较两天线的灵敏度值，该比较包括对两个天线的实时灵敏度值进行比较或者将两个天线的灵敏度值进行相减，得到一差值，然后比较该差值与预设值。S208. Compare the sensitivity values of the two antennas, and compare the real-time sensitivity values of the two antennas or subtract the sensitivity values of the two antennas to obtain a difference, and then compare the difference with a preset value.
S210，判断灵敏度差值是否大于预设值，若大于，则执行步骤S212，反之执行步骤S204，具体的，预设值为4dB，若该差值大于4dB，则执行步骤S212。S210: Determine whether the sensitivity difference is greater than a preset value. If yes, execute step S212, otherwise perform step S204. Specifically, the preset value is 4 dB. If the difference is greater than 4 dB, step S212 is performed.
S212，若差值大于预设值，则启动切换天线开关，将全向天线切换至分形天线，并返回步骤S204，优选的，这里的切换天线开关为双刀双掷开关。S212, if the difference is greater than the preset value, start switching the antenna switch, switch the omnidirectional antenna to the fractal antenna, and return to step S204. Preferably, the switching antenna switch here is a double-pole double-throw switch.
在本发明实施例提供的天线切换方法中，通过对设置在终端上的两个天线的对信号的接收灵敏度进行检测，判断检测到的灵敏度是否满足预设的切换条件，若满足，则将工作天线切换至备用天线，终端在正常工作时，只有工作天线接收信号，备用天线不接收；在本发明中，通过设置备用天线为辅助天线，且备用天线设置在工作天线之上，减低了备用天线的受干扰程度，解决了相关技术中，工作天线受干扰后会影响到手机的信号接收效率。 In the antenna switching method provided by the embodiment of the present invention, by detecting the receiving sensitivity of the pair of signals of the two antennas disposed on the terminal, it is determined whether the detected sensitivity satisfies a preset switching condition, and if it is satisfied, it will work. The antenna is switched to the backup antenna. When the terminal is in normal operation, only the working antenna receives the signal, and the standby antenna does not receive. In the present invention, the standby antenna is set as the auxiliary antenna, and the backup antenna is disposed on the working antenna, thereby reducing the backup antenna. The degree of interference has solved the related art, and the interference of the working antenna will affect the signal receiving efficiency of the mobile phone.
进一步的，备用天线设置为定向天线，并且将定向天线的方向设置与终端的无遮挡方向一致，尤其为分形天线，该定向天线具有与分形天线一样的特点，具有较好的方向性的增益，这样既能避免人体对手机信号的影响，减小手机辐射比收率，又能在同等输入功率条件下，方向性的聚集增益提高手机天线实际效率，也充分利用了定向天线具有较好的方向性增益的性能。Further, the backup antenna is configured as a directional antenna, and the direction setting of the directional antenna is consistent with the unobstructed direction of the terminal, especially a fractal antenna, which has the same characteristics as the fractal antenna and has better directional gain. In this way, the influence of the human body on the signal of the mobile phone can be avoided, the radiation ratio of the mobile phone can be reduced, and the directional accumulation gain can improve the actual efficiency of the mobile phone antenna under the same input power condition, and the directional antenna has a good direction. Performance of the gain.
