背景技术
目前，商用的通信设备的天线模组通常采用相控阵天线，这种天线模组具有电子波束扫描的能力，角域覆盖范围广，相控阵天线的天线单元越多，可以达到的EIRP(Effective Isotropic Radiated Power，等效全向辐射功率)和EIS(Equivalent Isotropic Sensitivity，有效的各向同性的敏感性)越高。但是，相控阵天线功耗大，成本极高，并且因为发热厉害，这种通信设备的尺寸会比较大。如果不采用相控阵天线作为天线模组，则会因为天线模组无电子波束扫描功能，难以实现信号宽角域覆盖，导致天线模组的信号强度差。

本公开实施例提供一种天线控制方法、控制终端以及通信系统。该天线控制方法应用于控制终端，天线包括天线模组及与天线模组连接的位姿调节装置，控制终端与天线电通信连接。
下面结合附图，对本公开的一些实施例作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参照图1，图1为本公开实施例提供的一种控制终端与天线电通信连接的结构示意图。
如图1所示，控制终端1与天线2电通信连接，天线2包括天线模组20以及位姿调节装置21。天线模组20与位姿调节装置21连接，控制终端1在与天线2电通信连接时，分 别与天线模组20以及位姿调节装置21电通信连接。控制终端1通过天线模组20收发信号，并控制位姿调节装置21调节天线模组的位姿。
在一些实施方式中，位姿调节装置21可以为一维转动装置，利用位姿调节装置21可以带动天线模组20在某个转动平面进行转动，示例性地，转动平面可以是水平面、垂直于水平面的俯仰面、或者不垂直于水平面的其他倾斜平面，在此不做限制。
在一些实施方式中，位姿调节装置21还可以为二维转动装置，利用位姿调节装置21可以带动天线模组20在某两个转动平面上进行转动；另外，位姿调节装置21还可以为更多维度的转动装置，在此不做限制。
在一些实施方式中，控制终端1在与天线2电通信连接时，形成CPE(Customer Premise Equipment，客户前置设备)产品，控制终端可以通过有线或者无线的方式为其他终端设备提供网络服务。
请参照图2，图2为本公开实施例提供的一种应用于控制终端的天线控制方法的流程示意图。
如图2所示，该天线控制方法包括步骤S10至步骤S12。
步骤S10、获取天线模组的方向图，并根据方向图的主瓣确定位姿调节装置在转动方向上的第一转动步长。
可以理解，天线模组20的方向图，即天线模组20的辐射方向图，是对天线模组20的辐射特性的图形描述。方向图中通常都有两个瓣或多个瓣，最大的瓣称为主瓣，其余的瓣称为副瓣或旁瓣，与主瓣相反方向上的旁瓣叫后瓣。
第一转动步长为位姿调节装置用于调节天线模组位姿的单位角度。在一些实施方式中，第一转动步长，是指确定位姿调节装置的转动方向所在的平面为参照平面后，在参照平面上，以主瓣最大辐射方向为中心，在最大辐射方向两侧的辐射强度降低到预设值时的两点间的夹角。
第一转动步长可以包括一个或者多个转动步长，第一转动步长与位姿调节装置21的转动方向相对应。示例性地，当位姿调节装置21为一维转动装置时，第一转动步长包括一个转动步长，对应位姿调节装置21的转动方向。当位姿调节装置21为二维转动装置时，第一转动步长包括两个转动步长，分别对应位姿调节装置21的两个转动方向。
在一些实施方式中，位姿调节装置包括用于使天线模组在水平方向上转动的水平转动组件、及用于使天线模组在俯仰方向上转动的俯仰转动组件。
根据方向图的主瓣确定位姿调节装置在转动方向上的第一转动步长，包括：获取方向图的主瓣在水平面上的半功率波瓣宽度作为第一水平步长，且获取主瓣在俯仰平面上的半功率波瓣宽度作为第一俯仰步长。
可以理解，在确定对应水平转动组件的第一水平步长时，因为水平转动组件的转动方向所在平面为水平面，因此，设定水平面为参照平面，获取主瓣在水平面上的半功率波瓣宽度作为第一水平步长。同理，在确定对应俯仰转动组件的第一俯仰步长时，因为俯仰转动组件的转动方向所在平面为俯仰平面，因此，设定俯仰平面为参照平面，获取主瓣在俯仰平面上的半功率波瓣宽度作为第一俯仰步长。
半功率波瓣宽度，是指确定参照平面后，在参照平面上，以主瓣最大辐射方向为中心，在最大辐射方向两侧的辐射强度降低到最大辐射强度的一半时的两点间的夹角。
在一些实施方式中，天线模组20可以与水平转动组件连接，另外，天线模组20也可以与俯仰转动组件连接，在此不做限制。
请参照图3，图3为本公开实施例提供的一种天线的结构示意图。
如图3所示，位姿调节装置21通过水平转动组件210以及俯仰转动组件211来调节天线模组20的位姿。俯仰转动组件211与天线模组20连接，利用俯仰转动组件211可以带动天线模组20在俯仰方向上进行转动；水平转动组件210与俯仰转动组件211连接，利用水平转动组件210带动俯仰转动组件211在水平方向上进行转动的过程中，可以间接带动天线模组20在水平方向上进行转动。
步骤S11、获取位姿调节装置在转动方向上的第一转动范围，并根据第一转动步长控制位姿调节装置在第一转动范围内调整天线模组的位姿，并且获取天线模组在各个位姿下的第一信号强度。
可以理解，位姿调节装置21在转动方向上所能够转动的角度范围，即为第一转动范围。确定第一转动范围以及第一转动步长后，即可根据第一转动步长控制位姿调节装置21在第一转动范围内进行转动，以调整天线模组20的位姿。
当天线模组20的位姿发生变化时，天线模组20的信号强度也会发生变化。以第一转动步长作为位姿调节装置21的单位转动步长来调节天线模组20的位姿时，所记录的天线模组20在各个位姿下的信号强度，即为第一信号强度。
示例性地，假设位姿调节装置21为一维转动装置，假设第一转动范围为0°-60°，假设第一转动步长为20°，则控制位姿调节装置21分别转动到0°、20°、40°以及60°。在位姿调节装置21根据第一转动步长在第一转动范围内调整天线模组20的位姿过程中，所记录的第一信号强度包括：位姿调节装置21转动到0°时天线模组20的信号强度、位姿调节装置21转动到20°时天线模组20的信号强度、位姿调节装置21转动到40°时天线模组20的信号强度，及位姿调节装置21转动到60°时天线模组20的信号强度。
在一些实施方式中，天线模组20的信号强度，可以为天线模组20的增益，也可以为天线模组的EIRP(Effective Isotropic Radiated Power，等效全向辐射功率)，还可以为其他可 以表征天线模组的信号质量的参数，在此不做限制。
在一些实施方式中，获取位姿调节装置在转动方向上的第一转动范围，并根据第一转动步长控制位姿调节装置在第一转动范围内调整天线模组的位姿，并且获取天线模组在各个位姿下的第一信号强度，包括：获取水平转动组件在水平方向上的可转动范围作为第一水平转动范围，并获取俯仰转动组件在俯仰方向上的可转动范围作为第一俯仰转动范围；控制水平转动组件根据第一水平步长使天线模组在第一水平转动范围内水平转动，并控制俯仰转动组件根据第一俯仰步长使天线模组在第一俯仰转动范围内俯仰转动，以调整天线模组的位姿；以及记录天线模组在各个位姿下的信号强度作为第一信号强度。
可以理解，水平转动组件210在水平方向上所能够转动的角度范围，即为第一水平转动范围；相应地，俯仰转动组件211在俯仰方向上所能够转动的角度范围，即为第一俯仰转动范围。
确定第一水平转动范围以及第一水平步长后，即可以第一水平步长作为转动步长，控制水平转动组件210带动天线模组20在第一水平转动范围内进行水平转动。相应地，确定第一俯仰转动范围以及第一俯仰步长后，即可以第一俯仰步长作为转动步长，控制俯仰转动组件211带动天线模组20在第一俯仰转动范围内进行俯仰转动。在此过程中，记录天线模组20在各个位姿下的信号强度作为第一信号强度。第一信号强度的数量与天线模组20的位姿数量相匹配。
示例性地，假设第一水平转动范围为0°至360°，第一水平步长为120°，第一俯仰转动范围为0°至45°，第一俯仰步长为15°。则在第一水平转动范围以及第一俯仰转动范围内，水平转动组件210以及俯仰转动组件211的转动组合以及第一信号强度的数量如下表一所示。
表一

步骤S12、从各个第一信号强度中筛选出第一目标信号强度，并控制位姿调节装置将天线模组调整到与第一目标信号强度对应的第一位姿。
可以理解，第一信号强度的数量与天线模组的位姿数量相匹配，第一目标信号强度为第一信号强度中的其中一个信号强度，为根据预设规则从第一信号强度中筛选得到。
每一个第一信号强度都与位姿调节装置21的转动角度存在映射关系，确定第一目标信号强度后，将位姿调节装置21转动到第一目标信号强度对应的转动角度，即可将天线模组20调整到第一位姿。
在一些实施方式中，从各个第一信号强度中筛选出第一目标信号强度，并控制位姿调节装置将天线模组调整到与第一目标信号强度对应的第一位姿，包括：确定各个第一信号强度中的最大值作为第一目标信号强度；获取在第一目标信号强度下，水平转动组件对应的水平转动角度作为第一水平角度；获取在第一目标信号强度下，俯仰转动组件对应的俯仰转动角度作为第一俯仰角度；以及控制水平转动组件转动到第一水平角度，且控制俯仰转动组件转动到第一俯仰角度。
可以理解，第一水平角度为天线模组20的信号强度为第一目标信号强度时，水平转动组件210的转动角度；同理，第一俯仰角度则为天线模组20的信号强度为第一目标信号强度时，俯仰转动组件211的转动角度。而第一位姿则为天线模组20的信号强度为第一目标信号强度时，天线模组20对应的位姿。
示例性地，如上表一所示，假设确定“信号强度9a”为第一目标信号强度，此时，水平转动组件210与“信号强度9a”对应的水平转动角度为240°，俯仰转动组件211与“信号强度9a”对应的俯仰转动角度为30°。则确定第一水平角度为240°，并确定第一俯仰角度为30°。控制水平转动组件210转动到240°，并控制俯仰转动组件211转动到30°后，天线模组20的位姿即为第一位姿，此时，天线模组20的信号强度可以达到第一目标信号强度。
在一些实施方式中，控制位姿调节装置将天线模组调整到与第一目标信号强度对应的第一位姿之后，方法还包括：计算第一转动步长与预设数值的比值作为第二转动步长，并获取位姿调节装置在天线模组处于第一位姿时的第一转动角度，且根据第一转动角度以及预设步长确定第二转动范围；根据第二转动步长控制位姿调节装置在第二转动范围内调整天线模组的位姿，并且获取天线模组在各个位姿下的第二信号强度；以及从各个第二信号强度中筛选出第二目标信号强度，并控制位姿调节装置将天线模组调整到与第二目标信号 强度对应的第二位姿。
可以理解，将第一转动步长与预设数值相除，所得到的相除结果即为第二转动步长。另外，天线模组20处于第一位姿时，位姿调节装置21当前的转动角度，即为第一转动角度。
以第一转动角度为基准值，以预设步长为距离，即可确定第二转动范围。示例性地，假设第一转动角度为w0，预设步长为w1，则确定w0-w1至w0+w1的范围为第二转动范围。
确定第二转动范围以及第二转动步长后，控制位姿调节装置21以第二转动步长为单位转动步长在第二转动范围内进行转动，以调节天线模组20的位姿。
当天线模组20的位姿发生变化时，天线模组20的信号强度也会发生变化。以第二转动步长作为位姿调节装置21的单位转动步长来调节天线模组20的位姿时，所记录的天线模组20在各个位姿下的信号强度，即为第二信号强度。
每一个第二信号强度与位姿调节装置21的转动角度都存在映射关系，从各个第二信号强度中选取最大值作为第二目标信号强度后，将位姿调节装置21转动到对应第二目标信号强度的转动角度，即可将天线模组20调整到第二位姿。
可以理解，在根据第一转动步长控制位姿调节装置21在第一转动范围内调整天线模组20的位姿，以确定第一目标信号强度，并控制位姿调节装置21将天线模组20调整到与第一目标信号强度对应的第一位姿的过程中，完成了天线模组20位姿的粗调，可以快速的让天线模组20获得良好的信号强度。
而在根据第二转动步长控制位姿调节装置21在第二转动范围内调整天线模组20的位姿，以确定第二目标信号强度，并控制位姿调节装置21将天线模组20调整到与第二目标信号强度对应的第二位姿的过程中。完成了天线模组20位姿的细调，可以让天线模组获得更优的信号强度。
在一些实施方式中，计算第一转动步长与预设数值的比值作为第二转动步长，并获取位姿调节装置在天线模组处于第一位姿时的第一转动角度，且根据第一转动角度以及预设步长确定第二转动范围，包括：以第一水平步长与预设数值的比值作为第二水平步长，并以第一俯仰步长与预设数值的比值作为第二俯仰步长；以第一水平角度为基准值，并以第一水平步长为半径确定第二水平转动范围；以及以第一俯仰角度为基准值，并以第一俯仰步长为半径确定第二俯仰转动范围。
可以理解，将第一水平步长与预设数值相除，所得到的相除结果即为第二水平步长；设第一水平角度为a，设第一水平步长为a1，则第二水平转动范围为a-a1至a+a1。
同理，将第一俯仰步长与预设数值相除，所得到的相除结果即为第二俯仰步长；设第 一俯仰角度为b，设第一俯仰步长为b1，则第二俯仰转动范围为b-b1至b+b1。
在一些实施方式中，根据第二转动步长控制位姿调节装置在第二转动范围内调整天线模组的位姿，并且获取天线模组在各个位姿下的第二信号强度，包括：控制水平转动组件根据第二水平步长使天线模组在第二水平转动范围内水平转动，并控制俯仰转动组件根据第二俯仰步长使天线模组在第二俯仰转动范围内俯仰转动，以调整天线模组的位姿；记录天线模组在各个位姿下的信号强度作为第二信号强度。
可以理解，确定第二水平转动范围以及第二水平步长后，即可以第二水平步长作为转动步长，控制水平转动组件210带动天线模组20在第二水平转动范围内进行水平转动。相应的，确定第二俯仰转动范围以及第二俯仰步长后，即可以第二俯仰步长作为转动步长，控制俯仰转动组件211带动天线模组20在第二俯仰转动范围内进行俯仰转动。在此过程中，记录天线模组20在各个位姿下的信号强度作为第二信号强度，并且，第二信号强度的数量与天线模组20的位姿数量相匹配。
在一些实施方式中，预设数值为大于1的数值，则计算得到的第二水平步长小于第一水平步长，并且计算得到的第二俯仰步长小于第一俯仰步长。在这种情况下，位姿调节专职21可以以更小的步长作为单位转动步长，来微调天线模组20的位姿，以让天线模组20获得更优的信号强度。
示例性地，假设第一水平角度为240°，并且第一水平步长为120°，则第二水平转动范围为180°至300°。假设第一俯仰角度为30°，第一俯仰步长为10°，则第二俯仰转动范围为20°至40°。假设预设数值为2，则第二水平步长为30°，第二俯仰步长为5°。则在第二水平转动范围以及第二俯仰转动范围内，水平转动组件210以及俯仰转动组件211的转动组合以及第二信号强度的数量如下表二所示。
表二

在一些实施方式中，从各个第二信号强度中筛选出第二目标信号强度，并控制位姿调节装置将天线模组调整到与第二目标信号强度对应的第二位姿，包括：确定各个第二信号强度中的最大值作为第二目标信号强度；获取在第二目标信号强度下，水平转动组件对应的水平转动角度作为第二水平角度；获取在第二目标信号强度下，俯仰转动组件对应的俯仰转动角度作为第二俯仰角度；控制水平转动组件转动到第二水平角度，且控制俯仰转动组件转动到第二俯仰角度。
可以理解，第二水平角度为天线模组20的信号强度为第二目标信号强度时，水平转动组件210的转动角度；同理，第二俯仰角度则为天线模组20的信号强度为第二目标信号强度时，俯仰转动组件211的转动角度。而第二位姿则为天线模组20的信号强度为第二目标信号强度时，天线模组20对应的位姿。
示例性地，如上表二所示，假设确定“信号强度22b”为第二目标信号强度，因为，水平转动组件210与“信号强度22b”对应的水平转动角度为210°，俯仰转动组件211与“信号强度22b”对应的俯仰转动角度为40°。则确定第二水平角度为210°，并确定第二俯仰角度为40°。此时，控制水平转动组件210转动到210°，并控制俯仰转动组件211转动到40°后，天线模组20的位姿即为第二位姿，此时，天线模组20的信号强度可以达到第二目标信号强度。
在一些实施方式中，天线模组包括抛物面反射面以及天线阵列，天线阵列为抛物面反射面的馈源。
请参照图3，图3为本公开实施例提供的一种天线的结构示意图。
如图3所示，天线模组20包括抛物面反射面201以及天线阵列202，天线阵列202为抛物面反射面201的馈源。
天线模组20在发射信号时，天线阵列202将待发射信号向抛物面反射面201的方向辐射，待发射信号经抛物面反射面201反射后，沿抛物面反射面201的法向平行辐射传输给基站。相应地，天线模组20在接收来自基站的待接收信号时，待接收信号经抛物面反射面201反射后，汇聚到天线阵列202中。
获取天线模组的方向图之前，该方法还包括：获取抛物面反射面的口径，并计算预设焦径比与口径的乘积作为初始焦距；获取抛物面反射面在轴线上的、与抛物面反射面相距初始焦距的位置作为初始相对位置，并获取与初始相对位置之间的距离在预设距离范围内的多个位置作为预选相对位置；计算天线阵列安置于各个预选相对位置时的增益数值；以及从各个预选相对位置中筛选天线阵列的增益数值最大时的位置作为目标相对位置，并根据目标相对位置将天线阵列与抛物面反射面固定连接。
在一些实施方式中，预设焦径比可以设置为1.02，假设抛物面反射面201的口径为80mm，则计算得到的初始焦距为81.6mm。另外，预设焦径比还可以根据情况需要选择其他数值，在此不做限制。
在一些实施方式中，预设距离范围可以为利用初始焦距与预设百分比的乘积确定的范围，另外，预设距离范围还可以根据其他方式确定，在此不做限制。
在一些实施方式中，在预设距离范围内的选取预选相对位置时，可以从抛物面反射面201的轴线上选取与初始相对位置的距离在预设距离范围内的多个点作为预选相对位置；另外，预选相对位置也不限定于一定要在抛物面反射面201的轴线上选取，也可以以初始相对位置为球心，以预设距离范围为半径选取多个点作为预选相对距离，在此不做限制。
在一些实施方式中，确定预设距离范围后，可以对抛物面反射面201以及天线阵列202进行仿真设计，以测算天线阵列202在各个相对位置的增益数值。另外，还可以利用预设的辅助机械设备调整天线阵列202的位置，并用天线增益测算仪器来测算天线阵列202在各个相对位置的增益数值；当然，还可以使用其他方式来计算天线这列202在不同位置下的增益，在此不做限制。
计算出天线阵列202安置在各个预选相对位置时对应的增益数值后，即可选取天线阵列202的增益数值最大时对应的预选相对位置作为目标相对位置。
相关技术中，使用天线阵列202作为抛物面反射面201的馈源，可能会存在相位偏移 的情况，从而导致天线模组20出现主瓣裂瓣的问题。可以理解，目标相对位置为相对于抛物面反射面201的轴心的相对位置，通过本实施方式所提供的技术方案，根据目标相对位置将天线阵列202与抛物面反射面201固定连接，可以尽可能的消除天线阵列202相位偏移的影响，避免天线模组20出现主瓣裂瓣的问题。
在一些实施方式中，天线阵列包括射频收发芯片、以及与射频收发芯片电通信连接的多个阵列布设并且等幅同相的毫米波天线。
控制终端通过中频同轴线缆与射频收发芯片电通信连接。
控制位姿调节装置将天线模组调整到与第一目标信号强度对应的第一位姿之后，该方法还包括：天线阵列在工作时，控制射频收发芯片将毫米波天线的工作频段下变频至预设频段。
可以理解，天线模组20的天线阵列202包括多个阵列布设并且等幅同相的毫米波天线，相比传统单天线馈源的抛物面天线，使用本实施方式中的天线阵列202馈源可增加发射功率，在同样的天线增益下可达到更高的EIRP，发射能力更强。
请参照图1，如图1所示，将天线模组20以及位姿调节装置21做成一个整体放在控制终端1外面，令控制终端1通过中频同轴线缆与天线2电通信连接，这样天线2和控制终端1的体积都不会做的很大。但是，通过中频同轴线缆来让控制终端1与天线2电通信连接，可能会对对毫米波天线的性能产生负面影响。
本实施方式中，利用射频收发芯片与毫米波天线电通信连接，并将控制终端1通过中频同轴线缆与射频收发芯片电通信连接，在天线阵列202工作时，利用射频收发芯片将毫米波天线的工作频段下变频至预设频段，可以在控制终端1通过中频同轴线缆与天线2电通信连接时影响毫米波天线的性能的问题。
在一些实施方式中，预设频段可以为15GHz以下、13GHz以下或者9GHz以下的频段，另外，还可以根据情况需要调整为其他频段，在此不做限制。
本公开实施例中，天线控制方法应用于控制终端，天线包括天线模组及与天线模组连接的位姿调节装置，控制终端与天线电通信连接。控制终端通过控制位姿调节装置进行转动来调节天线模组的位姿，以提高天线模组的信号强度。通过本公开所提供的技术方案，解决了相关的通信设备中，当不采用相控阵天线作为天线模组时，天线模组信号强度差的问题。
