现有的无线路由器大多采用全向天线实现无线覆盖。全向天线在水平方向图上表现为360°均匀辐射，也就是平常所说的无方向性。但是，全向天线的增益较小，通常只有3dBi～6dBi，且通信距离较短，信号转发速度较慢，导致这些无线路由器只能服务普通用户设备，不能服务中远距离弱场设备以及高速设备，因此现有无线路由器的应用受限。
发明内容
本申请实施例提供一种无线路由器及其控制方法，用于解决如何提升无线路由器的应用广泛性的问题。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种无线路由器，该无线路由器包括全向天线、定向天线和驱动装置。驱动装置与定向天线连接，驱动装置用于驱动定向天线转动，以使定向天线的波束指向与波束查找表中目标波束的指向重合，目标波束能够覆盖目标设备。其中，波束查找表包括定向天线在驱动装置的驱动下转动至多个不同方位时的波束组成的集合。
本申请实施例中，在借助全向天线满足普通设备接入的基础上，借助增益较高且波束指向可调的定向天线，可以满足中远距离弱场设备以及高速设备的接入，由此能够提升无线路由器的应用广泛性。在此基础上，在借助驱动装置驱动定向天线转动的过程中，只需使定向天线的波束指向与波束查找表内有限数量的多个波束中目标波束的指向重合，即可将定向天线调节至覆盖目标设备的位置，无需遍历定向天线在驱动装置的驱动下能够转动到的所有方位，因此控制难度较低，功耗和时延较小。
在第一方面的一种可能的实现方式中，驱动装置用于驱动定向天线绕第一轴线转动。波束查找表中多个波束组成多个波束子集，多个波束子集沿第一轴线的周向排列，波束子集至少包括指向与第一轴线垂直的第一波束。这样一来，当定向天线转动至波束指向与该多个第一波束的指向重合时，可以覆盖水平面内的目标设备，无线路由器可以适用于大平层房屋结构。
在第一方面的一种可能的实现方式中，沿第一轴线的周向，相邻两个波束子集中的第一波束之间的夹角大于或者等于驱动装置绕第一轴线驱动的步进精度角，小于或者等于定向天线的第一波束角。其中，第一波束角是指当定向天线的波束指向与第一轴线垂直时，在与第一轴线垂直的平面内，位于最大辐射方向的两侧，辐射功率下降第一预设阈值的两个方向之间的夹角。这样一来，波束查找表在沿第一轴线周向的360°范围内具有完备性，定向天线的波束指向可以调节至第一轴线周向360°范围内的多个位置，以使定向天线能够覆盖水平面内任意位置的目标设备。
在第一方面的一种可能的实现方式中，沿第一轴线的周向，相邻两个波束子集中的第一波束之间的夹角等于定向天线的第一波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
在第一方面的一种可能的实现方式中，驱动装置还用于驱动定向天线绕第二轴线转动；该第二轴线与第一轴线垂直，且第二轴线与定向天线的波束指向垂直。波束子集包括沿第二轴线的周向排列的多个波束，第一波束为该多个波束中的一个。这样一来，波束查找表中的多个波束分布于三维空间范围内，当定向天线转动至波束指向与该三维空间范围内的多个波束的指向重合时，可以覆盖三维空间范围内的目标设备，无线路由器可以适用于别墅、复式楼等房屋结构。
在第一方面的一种可能的实现方式中，沿第二轴线的周向，波束子集内相邻两个波束之间的夹角大于或者等于第二驱动装置绕第二轴线驱动的步进精度角，小于或者等于定向天线的第二波束角。其中，第二波束角是指当定向天线的波束指向与第一轴线垂直时，在与第二轴线垂直的平面内，位于最大辐射方向的两侧，辐射功率下降第二预设阈值的两个方向之间的夹角。这样一来，波束查找表在三维空间范围内具有完备性，定向天线的波束指向可以调节至三维空间范围内的多个位置，以使定向天线能够覆盖三维空间范围内任意位置的目标设备。
在第一方面的一种可能的实现方式中，沿第二轴线的周向，波束子集中相邻两个波束之间的夹角等于定向天线的第二波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
在第一方面的一种可能的实现方式中，无线路由器还包括控制器和检测系统。控制器与驱动装置电连接，控制器用于控制驱动装置驱动定向天线依次转动至多个方位，以使定向天线的波束指向分别与波束查找表中的多个波束的指向重合。检测系统用于在定向天线的波束指向分别与波束查找表中的多个波束的指向重合时，检测该定向天线接收到的来自目标设备的信号质量。该信号质量可以由接收信号强度、错误率、吞吐率、信道状态信息等指标中的至少一个进行评价。当信号质量由这些指标中的多个综合评价时，可以将该多个指标进行加权得到一个综合指标进行评价，也可以分别进行评价，在此不做具体限定。控制器与检测系统电连接，控制器还用于根据检测系统检测得到的多个信号质量，确定波束查找表中的目标波束，并控制驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中目标波束的指向重合。此无线路由器的结构简单，无需专门的定位装置，因此成本较低。
在第一方面的一种可能的实现方式中，无线路由器还包括定位装置和控制器。定位装置用于获取目标设备的位置信息。控制器与定位装置电连接，控制器用于根据定 位装置获取的位置信息，确定波束查找表中的目标波束，并控制驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中目标波束的指向重合。此无线路由器无需轮寻查找目标波束，能够快速确定目标波束，响应较快，延迟时间较短。
在第一方面的一种可能的实现方式中，定位装置为UWB天线。
在第一方面的一种可能的实现方式中，还包括射频收发系统，射频收发系统具有多个信号输出端，全向天线的数量为至少一个，定向天线的数量为至少一个，全向天线的数量和定向天线的数量之和大于射频收发系统的信号输出端的数量，射频收发系统的多个信号输出端与全向天线、定向天线之间还设有切换开关，该切换开关用于选择射频收发系统的多个信号输出端分别与至少一个全向天线和至少一个定向天线中的任意多个天线电连接，以使无线路由器在多种使用场景之间进行切换。
第二方面，又提供了一种无线路由器的控制方法，该无线路由器包括全向天线、定向天线和驱动装置，驱动装置与定向天线连接，控制方法包括：
获取全向天线接收到的来自第一目标设备的信号质量，以得到第一信号质量；
当第一信号质量小于第三预设阈值时，通过驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中的目标波束的指向重合，目标波束能够覆盖第一目标设备。其中，波束查找表包括定向天线在驱动装置的驱动下转动至多个不同方位时的波束组成的集合。
这样一来，在借助全向天线满足普通设备接入的基础上，借助增益较高且波束指向可调的定向天线，可以满足中远距离弱场设备以及高速设备的接入，由此能够提升无线路由器的应用广泛性。在此基础上，在借助驱动装置驱动定向天线转动的过程中，只需使定向天线的波束指向与波束查找表内有限数量的多个波束中目标波束的指向重合，即可将定向天线调节至覆盖目标设备的位置，无需遍历定向天线在驱动装置的驱动下能够转动到的所有方位，因此控制难度较低，功耗和时延较小。
在第二方面的一种可能的实现方式中，当第一信号质量小于第三预设阈值时，在通过驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中的目标波束的指向重合之前，控制方法还包括：在波束查找表中，确定目标波束。这样一来，可以实现目标波束的自动寻找，时延较小，效率较高。
在第二方面的一种可能的实现方式中，在波束查找表中，确定目标波束，包括：
通过驱动装置驱动定向天线依次转动至多个方位，以使定向天线的波束指向分别与波束查找表中的多个波束的指向重合，并在定向天线的波束指向分别与波束查找表中的多个波束的指向重合时，检测定向天线接收到的来自第一目标设备的信号质量，以得到多个信号质量；
根据多个信号质量，在波束查找表中确定目标波束。
这样一来，采用轮寻查找方式在波束查找表中确定目标波束，此方法简单，容易实现。
在第二方面的一种可能的实现方式中，驱动装置用于驱动定向天线绕第一轴线转动；波束查找表中多个波束组成多个波束子集，多个波束子集沿第一轴线的周向排列，波束子集至少包括指向与第一轴线垂直的第一波束；
通过驱动装置驱动定向天线依次转动至多个方位，以使定向天线的波束指向分别 与波束查找表中的多个波束的指向重合，并在定向天线的波束指向分别与波束查找表中的多个波束的指向重合时，检测定向天线接收到的来自第一目标设备的信号质量，以得到多个信号质量，包括：
通过驱动装置驱动定向天线绕第一轴线转动，以使定向天线的波束指向分别与多个波束子集中的第一波束的指向重合，并在定向天线的波束指向分别与多个波束子集中第一波束的指向重合时，检测定向天线接收到的来自第一目标设备的信号质量，以得到多个第三信号质量；其中，由于每个波束子集均包括第一波束，因此，多个波束子集中的第一波束是指多个第一波束，该多个第一波束分别属于该多个波束子集；
根据多个第三信号质量，确定目标波束子集，目标波束属于所述目标波束子集。
这样一来，当定向天线转动至波束指向分别与该多个第一波束的指向重合时，可以覆盖水平面内的目标设备，无线路由器可以适用于大平层房屋结构。
在第二方面的一种可能的实现方式中，驱动装置还用于驱动定向天线绕第二轴线转动；第二轴线与所述第一轴线垂直，且第二轴线与定向天线的波束指向垂直；波束子集包括沿第二轴线的周向排列的多个波束，第一波束为多个波束中的一个；
在确定目标波束子集之后，通过驱动装置驱动定向天线依次转动至多个方位，以使定向天线的波束指向分别与波束查找表中的多个波束的指向重合，并在定向天线的波束指向分别与波束查找表中的多个波束的指向重合时，检测定向天线接收到的来自第一目标设备的信号质量，以得到多个信号质量，还包括：
通过驱动装置驱动定向天线绕第二轴线转动，以使定向天线的波束指向分别与目标波束子集中多个波束的指向重合，并在定向天线的波束指向分别与目标波束子集中多个波束的指向重合时，检测定向天线接收到的来自第一目标设备的信号质量，以得到多个第四信号质量；
根据多个信号质量，在波束查找表中确定目标波束，包括：
根据多个第四信号质量，在目标波束子集中确定目标波束。
这样一来，波束查找表中的多个波束分布于三维空间范围内，通过定向天线转动至波束指向分别与该三维空间范围内的多个波束的指向重合时，可以覆盖三维空间范围内的目标设备，无线路由器可以适用于别墅、复式楼等房屋结构。
在第二方面的一种可能的实现方式中，在波束查找表中，确定目标波束，包括：
获取第一目标设备的位置信息；
根据位置信息，在波束查找表中确定目标波束。
这样一来，无线路由器无需轮寻查找目标波束，能够快速确定目标波束，响应较快，延迟时间较短。
在第二方面的一种可能的实现方式中，在得到第一信号质量之后，控制方法还包括：
判断第一信号质量是否大于或者等于第三预设阈值；
当第一信号质量大于或者等于第三预设阈值时，由全向天线覆盖第一目标设备进行工作。当第一信号质量大于或者等于第三预设阈值时，在采用全向天线覆盖第一目标设备的同时，还可以采用定向天线覆盖该第一目标设备，也可以停止使用定向天线，或者将定向天线用来覆盖其他目标设备。由此，能够实现资源的合理配置。
在第二方面的一种可能的实现方式中，控制方法还包括：
获取定向天线接收到的来自第一目标设备的信号质量，以得到第二信号质量；
通过驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中的目标波束的指向重合，包括：
当第一信号质量小于第三预设阈值，且第二信号质量小于第四预设阈值时，通过驱动装置驱动定向天线转动，以使定向天线的波束指向与波束查找表中的目标波束的指向重合。
这样一来，在全向天线以及当前波束指向下的定向天线均无法覆盖第一目标设备之后，再切换定向天线的波束指向，能够快速覆盖第一目标设备，降低大部分使用场景下的时延和功耗。
在第二方面的一种可能的实现方式中，获取定向天线接收到的来自第一目标设备的信号质量包括：
当第一信号质量小于第三预设阈值时，获取定向天线接收到的来自第一目标设备的信号质量。这样一来，优先考虑采用全向天线覆盖第一目标设备，在全向天线无法覆盖第一目标设备时，再采用定向天线覆盖第一目标设备，能够降低大部分使用场景下的时延和功耗。
在第二方面的一种可能的实现方式中，得到第二信号质量之后，控制方法还包括：
判断第二信号质量是否大于或者等于第四预设阈值；
当第二信号质量大于或者等于第四预设阈值时，由处于当前波束指向的定向天线覆盖第一目标设备进行工作。这样一来，借助当前波束指向的定向天线实现第一目标设备的覆盖，在实现第一目标设备的覆盖的同时，无需旋转定向天线，因此时延和功耗较低。
在第二方面的一种可能的实现方式中，定向天线的波束指向与波束查找表中的目标波束的指向重合之后，控制方法还包括：
由切换波束指向后的定向天线覆盖第一目标设备进行工作。
在第二方面的一种可能的实现方式中，由切换波束指向后的定向天线覆盖所述第一目标设备进行工作预设时间之后，控制方法还包括：
获取定向天线接收到的来自第一目标设备的信号质量，以得到第二信号质量；
判断第二信号质量是否大于或者等于第五预设阈值；
当第二信号质量大于或者等于第五预设阈值时，重新获取全向天线接收到的来自第一目标设备的信号质量。
这样一来，当信号质量变好时，可以重新确定全向天线是否能够覆盖第一目标设备，以实现资源的合理配置。
在第二方面的一种可能的实现方式中，得到第二信号质量之后，控制方法还包括：
判断第二信号质量是否小于或者等于第六预设阈值，第六预设阈值小于第五预设阈值；
当第二信号质量小于或者等于第六预设阈值时，重新获取全向天线接收到的来自第一目标设备的信号质量。这样一来，当信号质量变差时，可以重新寻找最优天线进行覆盖。
在第二方面的一种可能的实现方式中，控制方法还包括：
当第二信号质量小于第五预设阈值，且第二信号质量大于第六预设阈值时，保持由切换波束指向后的定向天线覆盖第一目标设备进行工作。
在第二方面的一种可能的实现方式中，控制方法还包括：
根据多个目标设备的设备信息确定多个目标设备的优先级，设备信息包括网络类型、设备类型、无线数据请求特性和设备使用信息中的至少一种，设备使用信息包括使用时间和使用概率中的至少一种；
将多个目标设备中优先级最高的目标设备确定为所述第一目标设备。
这样一来，可以提高波束切换的合理性。

为了提升无线路由器的应用广泛性，本申请实施例提供一种无线路由器，该无线路由器在服务普通用户设备的基础上，还能够服务中远距离弱场设备以及高速设备。具体的，本申请实施例提供的无线路由器在内置有全向天线的基础上，额外放置波束指向可调的定向天线，定向天线具有更高的天线增益(8dBi～12dBi)，以在借助全向天线满足普通设备接入的基础上，借助增益较高且波束指向可调的定向天线，满足中远距离弱场设备以及高速设备的接入，由此提升无线路由器的应用广泛性。
下面将结合附图详细介绍本申请的实施例，且在详细介绍本申请实施例之前，首先介绍本申请提供的无线覆盖系统的应用场景。
本申请提供一种无线路由器，该无线路由器可以是室外无线路由器，也可以为室内家用无线路由器，以下各实施例是以家用无线路由器为例进行介绍，这并不能认为是对本申请构成的特殊限制。同时，本申请提供的无线路由器可以支撑WiFi-2.4G、WiFi-5G、WiFi-6E及以上通用频段中的至少一个，本申请对此不做具体限定。
请参阅图1，图1为本申请一些实施例提供的一种家用的无线路由器100的结构示意图。需要说明的是，为了方便下文各实施例的描述，针对图1所示家用无线路由器100，建立XYZ坐标系。具体的,定义无线路由器100在处于家庭使用状态时的高度方向为Z轴方向，与Z轴方向垂直的平面为XY平面。可以理解的是，无线路由器100的坐标系可以根据实际需要进行灵活设置，在此不做具体限定。
无线路由器100包括壳体10。壳体10用于对内部电子器件起到防水防尘保护作用。壳体10的材料包括但不限于塑料。壳体10的形状包括但不限于圆柱形、方柱形、圆盘形、三棱柱、球形等等，图1给出了壳体10呈圆柱形的示例，这并不能认为是对壳体10的形状构成的特殊限制。在其他一些实施例中，无线路由器100也可以不设置该壳体10。
请继续参阅图1，无线路由器100还包括全向天线20和定向天线30。全向天线20和定向天线30用于实现无线路由器的无线覆盖。具体的，全向天线20和定向天线30用于支持WiFi-2.4G、WiFi-5G、WiFi-6E或者以上通用频段信号中的至少一种信号的发射与接收。在一些实施例中，全向天线20和定向天线30可以设置于壳体10内，以防止全向天线20和定向天线30受到外界环境的干扰。在其他一些实施例中，全向天线20和定向天线30也可以一部分设置于壳体10的内部，另一部分设置于壳体10的外部，或者全部设置于壳体10的外部，在本申请实施例中不做具体限定。
在一些实施例中，全向天线20与壳体10固定。全向天线20具有中心轴O，中心轴O与全向天线20在三维空间内的方向图的中心轴重合。请参阅图2，图2为图1所示无线路由器100内全向天线20在三维空间内的方向图，该全向天线20的方向图近似呈“苹果”状，中心轴O与该苹果状的方向图的中心轴重合。在一些实施例中，中心轴O沿Z轴方向延伸，这样一来，全向天线20在XY平面内表现为360°均匀辐射，在将无线路由器100应用于家庭时，全向天线20能够实现XY平面360°范围内的短距离覆盖。
请参阅图3，图3为图1所示无线路由器100内定向天线30在三维空间内的方向图。由图3可知，定向天线30在某个方向上发射和接收信号的能力特别强，而在其他的方向上发射和接收信号的能力较小或者为零。定向天线30的发射和接收信号能力最强的方向下文称之为定向天线30的波束指向。定向天线30具有较大的增益(8dBi～12dBi)，抗干扰能力较优。同时，相比于全向天线20，定向天线30的覆盖距离较远。举例说明，请参阅图4，图4为图1所示无线路由器100应用于大平层家庭房屋时全向天线20和定向天线30的一种覆盖范围示意图。具体的，图4中的(a)为全向天线20的一种覆盖范围示意图，图4中的(b)为定向天线30的一种覆盖范围示意图。在此示例中，全向天线20的覆盖距离较近，仅能够覆盖到距离相对较近的目标设备01，不能覆盖到距离相对较远的目标设备02。定向天线30的覆盖距离较远，既能覆盖到距离较近的目标设备01，又能覆盖到距离相对较远的目标设备02。由此可知，相比于全向天线20，定向天线30具有更远的覆盖距离，能够覆盖中远距离的目标设备。
需要说明的是，本申请实施例所述的目标设备是指需要与无线路由器100建立连接以达到上网目的的一类电子设备。具体的，目标设备包括但不限于个人电脑、无线 路由器、便携式电脑设备、移动终端设备(如PDA、掌上电脑设备、手机或智能手机等)、智能穿戴设备或者智能家居设备(如智能电视、智能冰箱、空调、洗衣机、空气净化器)等等。其中，智能穿戴设备包括但不限于手环、手表、增强现实(augmented reality，AR)眼镜、AR头盔、虚拟现实(virtual reality，VR)眼镜或者VR头盔等。
对比图2和图3可知，相比于全向天线20，定向天线30的波束集中在某一个方向或者多个方向，因此定向天线30的覆盖角度较窄。在此基础上，为了使全向天线20能够服务不同位置的目标设备，请返回参阅图1，无线路由器还包括驱动装置40，驱动装置40用于驱动定向天线30转动，以调节定向天线30的波束指向，使得定向天线30能够服务不同位置的目标设备。
在一些实施例中，请继续参阅图1，驱动装置40用于驱动定向天线30绕第一轴线L1转动。可选的，第一轴线L1与全向天线20的中心轴O平行，在其他一些可选实施例中，第一轴线L1也可以与全向天线20的中心轴O垂直或者相交，下文各实施例是在第一轴线L1与全向天线20的中心轴O平行的基础上进行的说明，这并不能认为是对本申请构成的特殊限制。由于全向天线20的中心轴O沿着无线路由器100的高度方向(也即是Z轴方向)延伸，因此第一轴线L1也沿着无线路由器100的高度方向延伸。这样一来，驱动装置40能够在XY平面内调节定向天线30的波束指向，以使定向天线30能够服务XY平面内的不同位置的目标设备，因此该无线路由器100能够适用于大平层家庭房屋结构。
驱动装置40的结构形式有多种。示例的，请参阅图5，图5为图1所示无线路由器100中一种驱动装置40的结构示意图。在本示例中，驱动装置40包括旋转电机41。旋转电机41可以为带减速器的电机，也可以为不带减速器的电机。旋转电机41的类型包括但不限于伺服电机、步进电机、力矩电机、开关磁阻电机和无刷直流电机。旋转电机41的输出轴的中轴线与第一轴线L1共线，旋转电机41的输出轴与定向天线30固定连接。
这样一来，当旋转电机41转动时，即可驱动定向天线30绕第一轴线L1转动。此驱动装置40的结构简单，成本较低，且旋转电机41与定向天线30直接连接，无需传动装置，因此传动效率较高，机械能损耗较小。
又示例的，请参阅图6，图6为图1所示无线路由器100中又一种驱动装置40的结构示意图。在本示例中，驱动装置40包括旋转电机41、主动锥齿轮42和从动锥齿轮43。旋转电机41可以为带减速器的电机，也可以为不带减速器的电机。旋转电机41的类型包括但不限于伺服电机、步进电机、力矩电机、开关磁阻电机和无刷直流电机。旋转电机41的输出轴与主动锥齿轮42连接，以驱动主动锥齿轮42转动。从动锥齿轮43与主动锥齿轮42啮合传动，从动锥齿轮43的中轴线与第一轴线L1共线，且从动锥齿轮43与定向天线30固定连接。
这样一来，当旋转电机41转动时，主动锥齿轮42和从动锥齿轮43啮合传动，可以驱动定向天线30绕第一轴线L1转动。齿轮传动的精度较高，传动效率较大，损耗小。同时通过锥齿轮传动，传动路径产生了转折，使得旋转电机41可以安装于第一轴线L1的一侧，从而降低了驱动装置40在Z轴方向上的占用高度。
又示例的，请参阅图7，图7为图1所示无线路由器中又一种驱动装置40的结构 示意图。在本示例中，驱动装置40包括旋转电机41、主动齿轮44和端面齿盘45。旋转电机41可以为带减速器的电机，也可以为不带减速器的电机。旋转电机41的类型包括但不限于伺服电机、步进电机、力矩电机、开关磁阻电机和无刷直流电机。旋转电机41的输出轴与主动齿轮44连接，以驱动主动齿轮44转动。主动齿轮44与端面齿盘45啮合传动，端面齿盘45的中轴线与第一轴线L1共线，端面齿盘45与定向天线30固定连接。
这样一来，当旋转电机41转动时，主动齿轮44和端面齿盘45啮合传动，可以驱动定向天线30绕第一轴线L1转动。齿轮传动的精度较高，传动效率较大，损耗小。同时通过主动齿轮与端面齿盘传动，一方面传动路径发生了转折，使得旋转电机41可以安装于第一轴线L1的一侧，从而降低了驱动装置40在Z轴方向上的占用高度，另一方面，端面齿盘的半径较大，拉远了旋转电机41与定向天线30的距离，使得旋转电机41能够安装至无线路由器内空间富裕的区域。
需要说明的是，驱动装置40除了包括上述旋转电机、以及旋转电机与齿轮传动装置的组合之外，还可以包括旋转电机与皮带传动装置、气动传动装置、液动传动装置等除了齿轮传动装置之外的传动装置的组合，本申请对此不做具体限定。
在一些实施例中，请参阅图8，图8为本申请又一些实施例提供的无线路由器100的结构示意图。图8所示无线路由器与图1所示无线路由器的区别之处在于：图8所示无线路由器中，驱动装置40除了用于驱动定向天线30绕第一轴线L1转动之外，还用于驱动定向天线30绕第二轴线L2转动，第二轴线L2与第一轴线L1垂直，且第二轴线L2还与定向天线30的波束指向垂直。由于定向天线30在绕第一轴线L1转动时，定向天线30的波束指向改变，因此第二轴线L2的延伸方向也随着定向天线30的波束指向的改变而改变。这样一来，驱动装置40能够在XYZ三维空间范围内调节定向天线30的波束指向，以使定向天线30能够服务XYZ三维空间范围内的不同位置的目标设备，因此无线路由器100能够适用于别墅、复式楼等房屋结构。
在上述实施例中，驱动装置40的结构形式有多种。示例的，驱动装置40可以为沿XYZ三维空间内的任意方向可动的球铰结构。
又示例的，请参阅图9，图9为图8所示无线路由器100中一种驱动装置40的结构示意图。在本示例中，驱动装置40包括第一驱动装置40a和第二驱动装置40b。第一驱动装置40a用于驱动定向天线30绕第一轴线L1转动，第一驱动装置40a的结构形式可以与图1所示无线路由器100中驱动装置40的结构形式相同，在此不做赘述。第二驱动装置40b连接于第一驱动装置40a与定向天线30之间，第一驱动装置40a在驱动定向天线30绕第一轴线L1转动的同时，还用于驱动第二驱动装置40b随着定向天线30一起绕第一轴线L1转动。第二驱动装置40b用于驱动定向天线30绕第二轴线L2转动。这样一来，借助第一驱动装置40a和第二驱动装置40b分别驱动定向天线30绕第一轴线L1和第二轴线L2转动，能够降低驱动装置的结构制作难度和成本，且两个驱动装置的驱动过程相互独立，能够保证驱动精度。
在上述实施例中，第二驱动装置40b的结构形式包括但不限于旋转电机、以及旋转电机与皮带传动装置、气动传动装置、液动传动装置以及齿轮传动装置等传动装置的组合。
示例的，请参阅图10，图10为图9所示驱动装置40的一种具体结构示意图。在本实施例中，第一驱动装置40a与图5所示的驱动装置40的结构形式相同，在此不做赘述。第二驱动装置40b包括旋转电机40b1，旋转电机40b1的定子部分与第一驱动装置40a的旋转电机的输出轴相对固定，第一驱动装置40a用于驱动旋转电机40b1绕第一轴线L1转动。在此基础上，定向天线30与旋转电机40b1的转子部分固定，旋转电机40b1用于驱动定向天线30绕第二轴线L2转动。此第二驱动装置40b的结构简单，传动效率高，机械能损耗较小。
又示例的，请参阅图11，图11为图9所示驱动装置40的又一种具体结构示意图。在本实施例中，第一驱动装置40a与图7所示的驱动装置40的结构形式相同，在此不做赘述。第二驱动装置40b也包括旋转电机40b1，旋转电机40b1的定子部分与第一驱动装置40a中端面齿盘相对固定，第一驱动装置40a用于驱动旋转电机40b1绕第一轴线L1转动。在此基础上，定向天线30与旋转电机40b1的转子部分固定，旋转电机40b1用于驱动定向天线30绕第二轴线L2转动。此第二驱动装置40b的结构简单，传动效率高，机械能损耗较小。
上述各实施例分别介绍了驱动装置40的多种结构形式，当然，驱动装置40还可以有其他结构形式，只要能够驱动定向天线30转动，以达到调节定向天线30的波束指向的目的即可。
在一些实施例中，定向天线30包括辐射体和反射板。辐射体和反射板中的至少一个转动，即可改变定向天线30的波束指向。在此基础上，驱动装置40可以与定向天线30的辐射体和/或反射板连接，以驱动定向天线30的辐射体和/或反射板转动，由此改变辐射体的口面朝向和反射板的反射方向，从而达到调节定向天线30的波束指向的目的。
本申请实施例中，采用物理机械结构(也即驱动装置40)驱动定向天线30转动，来达到调节定向天线30的波束指向的目的。相比于传统电路调节(比如波束赋形)方式，物理机械调节方式天线口面利用率高，具有更宽的波束以及更高的最大增益，且控制方法简单，控制电路的结构简单，同时可以使定向天线30覆盖更多的扇区。比如传动电路调节定向天线通常覆盖3～4个扇区，而本申请实施例采用物理机械结构调节的定向天线，根据驱动装置40的步进精度，可以覆盖的扇区数量远大于4个。
本申请实施例中，在借助全向天线20满足普通设备接入的基础上，借助增益较高且波束指向可调的定向天线，可以满足中远距离弱场设备以及高速设备的接入，由此能够提升无线路由器100的应用广泛性。
在通过驱动装置40调节定向天线30的波束指向，以使得定向天线30能够覆盖目标设备的过程中，为了简化控制难度，在一些实施例中，可以建立波束查找表。波束查找表包括定向天线30在驱动装置40的驱动下转动至多个不同方位时的波束组成的集合，也就是说，波束查找表包括多个波束组成的集合，该多个波束分别为定向天线30在驱动装置40的驱动下转动至多个不同方位时的波束。在此基础上，驱动装置40可以参照该波束查找表，驱动定向天线30转动，以使定向天线30的波束指向与波束查找表中目标波束的指向重合。其中，目标波束为波束查找表包括的多个波束中的一个，且目标波束能够覆盖目标设备。
这样一来，在借助驱动装置40驱动定向天线30转动的过程中，只需使定向天线30的波束指向与波束查找表内有限数量的多个波束中目标波束的指向重合，即可将定向天线30调节至覆盖目标设备的位置，无需遍历定向天线30在驱动装置40的驱动下能够转动到的所有方位，因此控制难度较低，功耗和时延较小。
在一些实施例中，当驱动装置40用于驱动定向天线30绕第一轴线L1转动时，波束查找表中多个波束组成沿第一轴线L1的周向排列的多个波束子集，每个波束子集至少包括指向与第一轴线L1垂直的第一波束a。请参阅图12，图12为本申请一些实施例提供的波束查找表中多个波束子集的第一波束a的结构示意图。该多个波束子集的第一波束a分别为定向天线30在驱动装置40的驱动下绕第一轴线L1转动至多个不同方位时的波束。这样一来，当定向天线30转动至波束指向与该多个第一波束a的指向重合时，可以覆盖XY平面内的目标设备，无线路由器可以适用于大平层房屋结构。
在上述实施例的基础上，为了使定向天线30能够覆盖XY平面内不同位置的目标设备，在一些实施例中，请继续参阅图12，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α大于或者等于驱动装置40绕第一轴线L1驱动的步进精度角，且小于或者等于定向天线30的第一波束角。
其中，相邻两个波束子集中的第一波束a之间的夹角α是指两个第一波束a的最大增益方向(也即是波束指向)之间夹角。
另外，驱动装置40绕第一轴线L1驱动的步进精度角是指驱动装置40绕第一轴线L1驱动的最小角度，该步进精度角大于0°。
再者，第一波束角是指当定向天线30的波束指向与第一轴线L1垂直时，在与第一轴线L1垂直的平面(也即是XY平面)内，位于最大辐射方向的两侧，辐射功率下降第一预设阈值的两个方向之间的夹角。其中，第一预设阈值可以为2dB、3dB、4dB、5dB等等，在此不做具体限定，该第一预设阈值具体可以根据实际需要进行选择。示例的，请参阅图13，图13为本申请一些实施例提供的无线路由器100中定向天线30的第一波束角a的示意图，该定向天线30的第一波束角是指在XY平面内，位于最大辐射方向D1的两侧，辐射功率下降第一预设阈值(比如为3dB)的两个方向D2和D3之间的夹角θ。
示例的，当相邻两个波束子集中的第一波束a之间的夹角α为20°时，在绕第一轴线L1的360°范围内有18个波束子集。当相邻两个波束子集中的第一波束a之间的夹角α为45°时，在绕第一轴线L1的360°范围内有8个波束子集。当相邻两个波束子集中的第一波束a之间的夹角α为90°时，在绕第一轴线L1的360°范围内有4个波束子集。
这样一来，波束查找表在沿第一轴线L1周向的360°范围内具有完备性，定向天线30的波束指向可以调节至第一轴线L1周向360°范围内的多个位置，以使定向天线30能够覆盖XY平面内任意位置的目标设备。
在一些实施例中，请返回参阅图12，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α等于定向天线30的第一波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
在上述实施例的基础上，当驱动装置40除了用于驱动定向天线30绕第一轴线L1 转动之外，还用于驱动定向天线30绕第二轴线L2转动时，波束查找表中的多个波束组成沿第一轴线L1的周向排列的多个波束子集，波束子集包括沿第二轴线L2的周向排列的多个波束，第一波束a为该多个波束中的一个。
由于第二轴线L2与定向天线30的波束指向垂直，且定向天线30在绕第一轴线L1转动时，定向天线30的波束指向改变，因此第二轴线L2的延伸方向也随着定向天线30的波束指向的改变而改变。这样，不同波束子集中的多个波束围沿不同延伸方向的第二轴线的周向排列。
举例说明，请参阅图14，图14为本申请又一些实施例提供的波束查找表的结构示意图，波束查找表包括沿第一轴线L1的周向排列的多个波束子集，该多个波束子集包括波束子集C1和波束子集C2，波束子集C1和波束子集C2均包括指向与第一轴线L1垂直的第一波束a，在通过驱动装置40驱动定向天线30转动，以使定向天线30的波束指向分别与波束子集C1中的第一波束a和波束子集C2中的第一波束a重合时，第二轴线L2分别为轴线L21和轴线L22，轴线L21和轴线L22的延伸方向不同。在此基础上，波束子集C1中的多个波束围绕轴线L21的周向排列，波束子集C2中的多个波束沿轴线L22的周向排列，也即是，波束子集C1中的多个波束和波束子集C2中的多个波束分别沿不同延伸方向的第二轴线的周向排列。
这样一来，波束查找表中的多个波束分布于XYZ三维空间范围内，当定向天线30转动至波束指向与该XYZ三维空间范围内的多个波束的指向重合时，可以覆盖XYZ三维空间范围内的目标设备，无线路由器可以适用于别墅、复式楼等房屋结构。
在上述实施例的基础上，为了使定向天线30能够覆盖XYZ三维空间范围内不同位置的目标设备，在一些实施例中，请继续参阅图14，沿第二轴线L2的周向w2，波束子集内相邻两个波束之间的夹角β大于或者等于驱动装置40绕第二轴线L2驱动的步进精度角，且小于或者等于定向天线30的第二波束角。
其中，波束子集内相邻两个波束之间的夹角β是指两个波束的最大增益方向(也即是波束指向)之间夹角。
另外，驱动装置40绕第二轴线L2驱动的步进精度角是指驱动装置40绕第二轴线L2驱动的最小角度，该步进精度角大于0°。
再者，第二波束角是指当定向天线30的波束指向与第一轴线L1垂直时，在与第二轴线L2垂直的平面(比如XZ平面)内，位于最大辐射方向的两侧，辐射功率下降第二预设阈值的两个方向之间的夹角。其中，第二预设阈值可以为2dB、3dB、4dB、5dB等等，该第二预设阈值可以与上述第一预设阈值相等，也可以与上述第一预设阈值不等，在此不做具体限定，该第二预设阈值具体可以根据实际需要进行选择。示例的，请参阅图15，图15为本申请一些实施例提供的无线路由器100中定向天线30的第二波束角的示意图，该定向天线30的第二波束角是指在XZ平面内，位于最大辐射方向D4的两侧，辐射功率下降第二预设阈值(比如为3dB)的两个方向D5和D6之间的夹角γ。
这样一来，波束查找表在XYZ三维空间范围内具有完备性，定向天线30的波束指向可以调节至XYZ三维空间范围内的多个位置，以使定向天线30能够覆盖XYZ三维空间范围内任意位置的目标设备。
在一些实施例中，沿第二轴线L2的周向w2，波束子集中相邻两个波束之间的夹角β等于定向天线30的第二波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
需要说明的是，波束查找表中波束集合的结构形式除了可以为图12和图14所示结构形式之外，还可以为其他结构形式。比如由图12中位于第一轴线L1的周向180°范围内的波束组成。又比如由图14中位于第一轴线L1的周向180°以及位于第二轴线L2的周向的90°范围内的波束组成，本申请实施例对此不做具体限定。
根据以上各实施例的描述，波束查找表包括多个波束，为了在该多个波束中确定目标波束，可以采用下面两种实施例实施，该两种实施例包括下述实施例一和实施例二。
实施例一：请参阅图16，图16为本申请又一些实施例提供的无线路由器100的结构示意图。在本实施例中，无线路由器100还包括控制器50和检测系统60。
控制器50可以包括处理器或必要的逻辑电路。该处理器可以是基带处理器、数字信号处理器、微处理器或中央处理单元等。控制器50与驱动装置40电连接，控制器50用于控制驱动装置40驱动定向天线30依次转动至多个方位，以使定向天线30的波束指向分别与波束查找表中的多个波束的指向重合。其中，该多个波束可以为波束查找表中的全部波束，也可以为波束查找表中的部分波束，在此不做具体限定。
检测系统60用于在定向天线30的波束指向分别与波束查找表中的多个波束的指向重合时，检测定向天线30接收到的来自目标设备的信号质量。该信号质量可以由接收信号强度(received signal strength indication，RSSI)、错误率(PER)、吞吐率、信道状态信息(channel status information，CSI)等指标中的至少一个进行评价。当信号质量由这些指标中的多个综合评价时，可以将该多个指标进行加权得到一个综合指标进行评价，也可以分别进行评价，在此不做具体限定。
控制器50与检测系统60电连接，控制器50还用于根据检测系统60检测得到的多个信号质量，确定波束查找表中的目标波束。可选的，控制器50确定信号质量最优时，波束查找表中与定向天线30的波束指向重合的波束为目标波束。
此无线路由器的结构简单，无需专门的定位装置，因此成本较低。
在上述实施例的基础上，控制器50还用于控制驱动装置40驱动定向天线30转动，以使定向天线30的波束指向分别与波束查找表中目标波束的指向重合。由此实现自动化控制，简化控制难度，保证驱动精度。
实施例二：请参阅图17，图17为本申请又一些实施例提供的无线路由器100的结构示意图。在本实施例中，还包括定位装置70和控制器50。
定位装置70包括但不限于无载波通信(ultra wideband，UWB)天线。定位装置70用于获取目标设备的位置信息。控制器50与定位装置70电连接，控制器50用于根据定位装置70获取的位置信息，确定波束查找表中的目标波束。可选的，控制器50确定波束查找表中波束指向与目标位置相对于无线路由器的位置方向之间的夹角最小的波束为目标波束。此无线路由器无需轮寻查找目标波束，因此响应速度较快，延迟时间较短。
在上述实施例的基础上，控制器50还用于控制驱动装置40驱动定向天线30转动， 以使定向天线30的波束指向与波束查找表中目标波束的指向重合。由此实现自动化控制，简化控制难度，保证驱动精度。
以上各实施例介绍了全向天线20的数量和定向天线30的数量均为一个的情况。当然，全向天线20的数量和定向天线30的数量也可以为多个，或者全向天线20的数量为一个，定向天线30的数量为多个，或者全向天线20的数量为多个，定向天线30的数量为一个。也即是，全向天线20的数量为至少一个，定向天线30的数量为至少一个。
当全向天线20的数量为多个时，借助该多个全向天线20可以支持多个不同信道信号的收发，由此进一步提高无线路由器100的应用广泛性。
当定向天线30的数量为多个时，借助该多个定向天线30，可以实现多用户下行并发。
通过不同数量的全向天线20与不同数量的定向天线30组合，可以得到不同规格的无线路由器100。无线路由器100的规格可以为MIMO2X2、MIMO3X3和MIMO4X4。当无线路由器100的规格为MIMO2X2时，全向天线20的数量与定向天线30的数量之和为2个，具体的，全向天线20的数量为1个，定向天线30的数量也为1个。当无线路由器100的规格为MIMO3X3时，上全向天线20的数量与定向天线30的数量之和为3个，具体的，全向天线20的数量为1个，至定向天线30的数量为2个；或者，全向天线20的数量为2个，定向天线30的数量为1个。当无线路由器100的规格为MIMO4X4时，全向天线20的数量与定向天线30的数量之和为4个，具体的，全向天线20的数量为1个，定向天线30的数量为3个；或者，全向天线20的数量为2个，定向天线30的数量为2个；或者，全向天线20的数量为3个，定向天线30的数量为1个。具体的，无线路由器100的规格、以及不同规格下全向天线20的数量和定向天线30的数量记录在表1中。

为了向全向天线和定向天线输出射频信号或者接收来自全向天线和定向天线的射频信号，请参阅图18，图18为本申请一些实施例提供的无线路由器100的内部电路 图。无线路由器100还包括射频收发系统80，射频收发系统80用于实现上述至少一个全向天线20以及上述至少一个定向天线30的信号收发。具体的，射频收发系统80具有多个信号输出端80a，该多个信号输出端80a分别与上述至少一个全向天线20以及至少一个定向天线30电连接。射频收发系统80用于生成射频信号，并借助多个信号输出端80a，将生成的射频信号输出至该至少一个全向天线20以及至少一个定向天线30，以实现信号的发射。同时，射频收发系统80还可以借助该多个信号输出端80a，接收该至少一个全向天线20以及该至少一个定向天线30接收的信号，以实现信号的接收。
射频收发系统80的结构形式有多种，在一些实施例中，请参阅图19，图19为图18所示无线路由器100内射频收发系统80的结构示意图。射频收发系统80包括多条射频收发链路(也称为射频收发器或者TRx)81。多条射频收发链路81的数量与上述多个信号输出端80a的数量相同，每条射频收发链路81均具有一个信号输出端80a。
在一些实施例中，请继续参阅图19，射频收发链路81可以包括双工器811、发射通路812和接收通路813。具体来说，双工器811用于将发射通路812以及接收通路813连接至信号输出端80a。射频收发链路81后端可以连接用于生成发送信号或处理接收信号的处理电路82。该处理电路82可以包括处理器或必要的逻辑电路，用于进行基带信号处理或数字信号处理。处理器可以是基带处理器、数字信号处理器、微处理器或中央处理单元等。处理电路82可以包括在射频收发链路81内，也可以独立于射频收发链路81之外。
双工器811可以是频分双工器或时分双工器，用于将发送信号从发射通路812耦合至信号输出端80a，将接收信号从信号输出端80a耦合至接收通路813。具体的，双工器811可以是以下一种或多种的组合：单刀多掷开关、环形器以及滤波器。

接收通路813用于处理并传输信号输出端80a接收的接收信号至后端的处理电路82。接收通路813可以包括低噪声放大器(low noise amplifier，LNA)和下混频器。其中，LNA能够将信号输出端80a接收到的微弱信号进行放大，并且在放大信号的过程中降低噪声干扰。也叫解调器，用于将接收通路813中传输的接收信号的频率从第三频率转换为第四频率，第三频率大于第四频率。典型的，下混频器则用于将射频信号解调为基带信号或中频信号。在接收通路813中，下混频器和LNA的位置也是可以互换的。
射频收发系统80的信号输出端80a的数量可以与全向天线20的数量和定向天线 30的数量之和相等。示例的，请参阅图18和图19，全向天线20的数量为2个，定向天线30的数量也为2个，则全向天线20的数量和定向天线30的数量之和为4个，射频收发系统80的信号输出端80a的数量也为4个。在此基础上，射频收发系统80中，部分信号输出端80a与全向天线20一一对应电连接，另外部分信号输出端80a与定向天线30一一对应电连接。示例的，请继续参阅图18和图19，射频收发系统80的4个信号输出端80a中，2个信号输出端80a分别与2个全向天线20电连接，另外2个信号输出端80a分别与2个定向天线30电连接。这样一来，可以同时实现无线路由器中全向天线20和定向天线30的信号收发。
在其他一些实施例中，在射频收发系统80的信号输出端80a的数量不变的前提下，可以增加全向天线20和/或定向天线30的数量，以使得全向天线20的数量和定向天线30的数量之和大于射频收发系统80的信号输出端80a的数量。在此基础上，请参阅图20，图20为本申请又一些实施例提供的无线路由器100的内部电路图。射频收发系统80的信号输出端80a与全向天线20、定向天线30之间还设有切换开关90，该切换开关90用于选择射频收发系统80的多个信号输出端80a分别与全向天线20和定向天线30中的任意多个天线电连接，以使无线路由器在多种使用场景之间进行切换。
举例说明，在射频收发系统80的信号输出端80a的数量不变的前提下，仅增加全向天线20的数量，以使得全向天线20的数量与射频收发系统80的信号输出端80a的数量相等，全向天线20的数量和定向天线30的数量之和大于射频收发系统80的信号输出端80a的数量。具体的，MIMO2X2、MIMO3X3和MIMO4X4规格的无线路由器100中全向天线20的数量和定向天线30的数量记载在下表2中。

其中，第一目标设备为无线路由器的覆盖范围内的一个电子设备，该电子设备包括但不限于个人电脑、无线路由器、便携式电脑设备、移动终端设备(如PDA、掌上电脑设备、手机或智能手机等)、智能穿戴设备或者智能家居设备(如智能电视、智能冰箱、空调、洗衣机、空气净化器)等等。其中，智能穿戴设备包括但不限于手环、手表、AR眼镜、AR头盔、VR眼镜或者VR头盔等。
另外，第一信号质量Q1可以由RSSI、PER、吞吐率、CSI等指标中的至少一个进行评价。当第一信号质量Q1由这些指标中的多个综合评价时，可以将该多个指标进行加权得到一个综合指标进行评价，也可以分别进行评价，在此不做具体限定。
S200：当第一信号质量Q1小于第三预设阈值时，通过驱动装置40驱动定向天线30转动，以使定向天线30的波束指向与波束查找表中的目标波束的指向重合，该目标波束能够覆盖第一目标设备。由此切换定向天线30的波束指向，以使定向天线30能够覆盖到第一目标设备。
其中，驱动装置40用于驱动定向天线30转动，以调节定向天线30的波束指向， 使得定向天线30能够服务不同位置的目标设备。
这样一来，在借助全向天线满足普通设备接入的基础上，借助增益较高且波束指向可调的定向天线，可以满足中远距离弱场设备以及高速设备的接入，由此能够提升无线路由器的应用广泛性。在此基础上，在借助驱动装置驱动定向天线转动的过程中，只需使定向天线的波束指向与波束查找表内有限数量的多个波束中目标波束的指向重合，即可将定向天线调节至覆盖目标设备的位置，无需遍历定向天线在驱动装置的驱动下能够转动到的所有方位，因此控制难度较低，功耗和时延较小。
在一些实施例中，驱动装置40用于驱动定向天线30绕第一轴线L1转动。可选的，第一轴线与全向天线20的中心轴O平行。由于全向天线20的中心轴O通常沿着无线路由器的高度方向(也即是Z轴方向)延伸，因此第一轴线L1也沿着无线路由器的高度方向延伸。这样一来，驱动装置40能够在水平面(也即是XY平面)内调节定向天线30的波束指向，以使定向天线30能够服务水平面内的不同位置的目标设备，因此该无线路由器能够适用于大平层家庭房屋结构。
在上述实施例的基础上，可选的，驱动装置40还用于驱动定向天线30绕第二轴线L2转动，第二轴线L2与第一轴线L1垂直，且第二轴线L2还与定向天线30的波束指向垂直。由于定向天线30在绕第一轴线L1转动时，定向天线30的波束指向改变，因此第二轴线L2的延伸方向也随着定向天线30的波束指向的改变而改变。这样一来，驱动装置40能够在三维空间范围内调节定向天线30的波束指向，以使定向天线30能够服务三维空间范围内的不同位置的目标设备，因此无线路由器能够适用于别墅、复式楼等房屋结构。
驱动装置40的结构形式有多种。具体的，驱动装置40可以包括上述旋转电机、以及旋转电机与齿轮传动装置、皮带传动装置、气动传动装置、液动传动装置等传动装置的组合，本申请对此不做具体限定。
波束查找表包括定向天线30在驱动装置40的驱动下转动至多个不同方位时的波束组成的集合。也就是说，波束查找表包括多个波束组成的集合，该多个波束分别为定向天线30在驱动装置40的驱动下转动至多个不同方位时的波束。
当驱动装置40用于驱动定向天线30绕第一轴线L1转动时，波束查找表中多个波束组成沿第一轴线L1的周向排列的多个波束子集，每个波束子集至少包括指向与第一轴线L1垂直的第一波束a。该多个波束子集的第一波束a分别为定向天线30在驱动装置40的驱动下绕第一轴线L1转动至多个不同方位时的波束。这样一来，当定向天线30转动至波束指向与该多个第一波束a的指向重合时，可以覆盖XY平面内的目标设备，无线路由器可以适用于大平层房屋结构。
为了保证波束查找表在XY平面内具有完备性，在一些实施例中，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α大于或者等于驱动装置40绕第一轴线L1驱动的步进精度角，且小于或者等于定向天线30的第一波束角。其中，相邻两个波束子集中的第一波束a之间的夹角α是指两个第一波束a的最大增益方向(也即是波束指向)之间夹角。另外，驱动装置40绕第一轴线L1驱动的步进精度角是指驱动装置40绕第一轴线L1驱动的最小角度，该步进精度角大于0°。再者，第一波束角是指当定向天线30的波束指向与第一轴线L1垂直时，在与第一轴线L1垂直 的平面(也即是XY平面)内，位于最大辐射方向的两侧，辐射功率下降第一预设阈值的两个方向之间的夹角。其中，第一预设阈值可以为2dB、3dB、4dB、5dB等等，在此不做具体限定，该第一预设阈值具体可以根据实际需要进行选择。这样一来，波束查找表在沿第一轴线L1周向的360°范围内具有完备性，定向天线30的波束指向可以调节至第一轴线L1周向360°范围内的多个位置，以使定向天线30能够覆盖XY平面内任意位置的目标设备。
在一些实施例中，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α等于定向天线30的第一波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
当驱动装置40除了用于驱动定向天线30绕第一轴线L1转动之外，还用于驱动定向天线30绕第二轴线L2转动时，波束查找表中的多个波束组成沿第一轴线L1的周向排列的多个波束子集，波束子集包括沿第二轴线L2的周向排列的多个波束，第一波束a为该多个波束中的一个。由于第二轴线L2与定向天线30的波束指向垂直，且定向天线30在绕第一轴线L1转动时，定向天线30的波束指向改变，因此第二轴线L2的延伸方向也随着定向天线30的波束指向的改变而改变。这样，不同波束子集中的多个波束围沿不同延伸方向的第二轴线的周向排列。这样一来，波束查找表中的多个波束分布于XYZ三维空间范围内，当定向天线30转动至波束指向与该XYZ三维空间范围内的多个波束的指向重合时，可以覆盖XYZ三维空间范围内的目标设备，无线路由器可以适用于别墅、复式楼等房屋结构。
为了保证波束查找表在XYZ三维空间范围内内具有完备性，在一些实施例中，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α大于或者等于驱动装置40绕第一轴线L1驱动的步进精度角，且小于或者等于定向天线30的第一波束角。在此基础上，沿第二轴线L2的周向w2，波束子集内相邻两个波束之间的夹角β大于或者等于驱动装置40绕第二轴线L2驱动的步进精度角，且小于或者等于定向天线30的第二波束角。其中，波束子集内相邻两个波束之间的夹角β是指两个波束的最大增益方向(也即是波束指向)之间夹角。另外，驱动装置40绕第二轴线L2驱动的步进精度角是指驱动装置40绕第二轴线L2驱动的最小角度，该步进精度角大于0°。再者，第二波束角是指当定向天线30的波束指向与第一轴线L1垂直时，在与第二轴线L2垂直的平面(比如XZ平面)内，位于最大辐射方向的两侧，辐射功率下降第二预设阈值的两个方向之间的夹角。其中，第二预设阈值可以为2dB、3dB、4dB、5dB等等，该第二预设阈值可以与上述第一预设阈值相等，也可以与上述第一预设阈值不等，在此不做具体限定，该第二预设阈值具体可以根据实际需要进行选择。这样一来，波束查找表在XYZ三维空间范围内具有完备性，定向天线30的波束指向可以调节至XYZ三维空间范围内的多个位置，以使定向天线30能够覆盖XYZ三维空间范围内任意位置的目标设备。
在一些实施例中，沿第一轴线L1的周向w1，相邻两个波束子集中的第一波束a之间的夹角α等于定向天线30的第一波束角。同时沿第二轴线L2的周向w2，波束子集中相邻两个波束之间的夹角β等于定向天线30的第二波束角。这样一来，波束查找表中的波束的数量较少，控制难度较低，功耗和时延较小。
在一些实施例中，请参阅图22，图22为本申请又一些实施例提供的无线路由器的控制方法的流程图，在步骤S100之后，控制方法还包括：
步骤S801：判断第一信号质量是否大于或者等于第三预设阈值。
步骤S802：当第一信号质量大于或者等于第三预设阈值时，由全向天线20覆盖第一目标设备进行工作。当第一信号质量大于或者等于第三预设阈值时，在采用全向天线覆盖第一目标设备的同时，还可以采用定向天线覆盖该第一目标设备，也可以停止使用定向天线，或者将定向天线用来覆盖其他目标设备。由此，能够实现资源的合理配置。在一些实施例中，步骤S802包括：向全向天线20的射频收发链路下发参数，该参数包括但不限于发射功率和协议软件参数等；进入标准工作状态。全向天线20覆盖第一目标设备第一预设时间T1之后，可以返回步骤S100，以进入下一次循环。其中，第一预设时间T3可以指步骤S802中标准工作状态的持续时间。第一预设时间T1包括但不限于0.1秒(s)、0.2s、0.3s等等，在此不做具体限定。
在一些实施例中，请参阅图23，图23为本申请又一些实施例提供的无线路由器的控制方法的流程图，控制方法还包括：
步骤S300：获取定向天线30接收到的来自第一目标设备的信号质量，以得到第二信号质量Q2。在此基础上，步骤S200包括：当第一信号质量Q1小于第三预设阈值，且第二信号质量Q2小于第四预设阈值时，通过驱动装置40驱动定向天线30转动，以使定向天线30的波束指向与波束查找表中的目标波束的指向重合。这样一来，在全向天线20以及当前波束指向下的定向天线30均无法覆盖第一目标设备之后，再切换定向天线30的波束指向，能够快速覆盖第一目标设备，降低大部分使用场景下的时延和功耗。
在上述实施例中，第二信号质量Q2也可以由RSSI、PER、吞吐率、CSI等指标中的至少一个进行评价。当第二信号质量Q2由这些指标中的多个综合评价时，可以将该多个指标进行加权得到一个综合指标进行评价，也可以分别进行评价，在此不做具体限定。第二信号质量Q2的评价指标可以与第一信号质量Q1的评价指标相同，也可以与第一信号质量Q1的评价指标不同。举例说明，当第一信号质量Q1通过RSSI、PER、吞吐率、CSI四个指标加权后的综合指标进行综合评价时，第二信号质量Q2也通过RSSI、PER、吞吐率、CSI四个指标加权后的综合指标进行综合评价，且各指标的加权值相同，这样第一信号质量Q1与第二信号质量Q2的评价指标相同，若上述加权值不同，则第一信号质量Q1与第二信号质量Q2的评价指标不同。
在图23所示的控制方法中，步骤S300可以与步骤S100同时操作，也可以在步骤S100之后操作，还可以在步骤S100之前操作，在此不做具体限定。在一些实施例中，步骤S300位于步骤S100之后，具体的，步骤S300包括：当第一信号质量小于第三预设阈值时，获取定向天线接收到的来自第一目标设备的信号质量。这样一来，优先考虑采用全向天线覆盖第一目标设备，在全向天线无法覆盖第一目标设备时，再采用定向天线覆盖第一目标设备，能够降低大部分使用场景下的时延和功耗。
在一些实施例中，在步骤S300之后，请继续参阅图23，控制方法还包括下面的步骤S901和步骤S902。
步骤S901：判断第二信号质量是否大于或者等于第四预设阈值。
步骤S902：当第二信号质量大于或者等于第四预设阈值时，由处于当前波束指向的定向天线覆盖第一目标设备。这样一来，借助当前波束指向的定向天线实现第一目标设备的覆盖，在实现第一目标设备的覆盖的同时，无需旋转定向天线，因此时延和功耗较低。在一些实施例中，步骤S902包括：向定向天线30的射频收发链路下发参数，该参数包括但不限于发射功率和协议软件参数等；进入标准工作状态。定向天线30覆盖第一目标设备第二预设时间T2之后，可以返回步骤S100，以进入下一次循环。其中，第二预设时间T2可以指步骤S902中标准工作状态的持续时间。第二预设时间T2包括但不限于0.1s、0.2s、0.3s等等，在此不做具体限定。且第二预设时间T2与第一预设时间T1可以相等，也可以不等，在此不做具体限定。在此基础上，请继续参阅图23，步骤S200位于步骤S901之后。
在一些实施例中，请继续参阅图23，在上述步骤S200之后，还包括步骤S1000。步骤S1000：由切换波束指向后的定向天线30覆盖第一目标设备进行工作。具体的，步骤S1000可以包括：向定向天线30的射频收发链路下发参数，该参数包括但不限于发射功率和协议软件参数等；进入标准工作状态。其中，向定向天线30的射频收发链路下发参数的步骤除了在切换波束指向之后执行之外，还可以在切换波束指向之前执行，或者与切换波束指向同时执行，在此不做具体限定。定向天线30覆盖第一目标设备第三预设时间T3之后，可以返回步骤S100，以进入下一次循环。其中，第三预设时间T3可以指步骤S1000中标准工作状态的持续时间。第三预设时间T3包括但不限于0.1s、0.2s、0.3s等等，在此不做具体限定。且第三预设时间T3与第一预设时间T1、第二预设时间T2可以相等，也可以不等，在此不做具体限定。请参阅图24，图24为本申请又一些实施例提供的无线路由器的控制方法的流程图。本实施例中，步骤S200之后，控制方法还包括步骤S1000，步骤S1000：由切换波束指向后的定向天线覆盖第一目标设备进行工作。
在一些实施例中，请继续参阅图24，上述步骤S300在步骤S1000操作预设时间T4之后执行。预设时间T4包括但不限于0.1s、0.2s、0.3s，在此不做具体限定。在此基础上，在步骤S300之后，控制方法还包括步骤S903和步骤S904。步骤S903：判断第二信号质量是否大于或者等于第五预设阈值；步骤S903：当第二信号质量大于或者等于第五预设阈值时，重新进入步骤S100。这样一来，当信号质量变好时，可以重新确定全向天线20是否能够覆盖第一目标设备，以实现资源的合理配置。
在一些实施例中，请继续参阅图24，步骤S903还包括：判断第二信号质量是否小于或者等于第六预设阈值，第六预设阈值小于第五预设阈值。判断第二信号质量是否小于或者等于第六预设阈值的步骤可以在判断第二信号质量是否大于或者等于第五预设阈值的步骤之后，也可以在判断第二信号质量是否大于或者等于第五预设阈值的步骤之前，还可以同时判断，在此不做具体限定。在此基础上，请继续参阅图24，在步骤S903之后，控制方法还包括：当第二信号质量小于或者等于第六预设阈值时，重新进入步骤S100。这样一来，当信号质量变差时，可以重新寻找最优天线进行覆盖。
在一些实施例中，请继续参阅图24，在步骤S903之后，还包括：当第二信号质量小于第五预设阈值，且第二信号质量大于第六预设阈值时，保持步骤S1000继续工作。
在一些实施例中，请继续参阅图23或图24，当第一信号质量Q1小于第三预设阈值，且第二信号质量Q2小于第四预设阈值时，在通过驱动装置40驱动定向天线30转动，以使定向天线30的波束指向与波束查找表中的目标波束的指向重合之前，控制方法还包括下面步骤S400。
步骤S400：在波束查找表中，确定目标波束。该步骤S400在步骤S100和步骤S200之后。
在一些实施例中，请参阅图25，图25为图23或图24所示控制方法中一种确定目标波束的方法流程图。在本实施例中，步骤S400包括下面的步骤S410和步骤S420。
步骤S410：通过驱动装置40驱动定向天线30依次转动至多个方位，以使定向天线30的波束指向分别与波束查找表中的多个波束的指向重合，并在该定向天线30的波束指向与波束查找表中的多个波束的指向重合时，检测定向天线30接收到的来自第一目标设备的信号质量，以得到多个信号质量。其中，波束查找表中的多个波束可以为波束查找表中的全部波束，也可以为波束查找表中的部分波束，在此不做具体限定。
步骤S420：根据多个信号质量，在波束查找表中确定目标波束。
这样一来，采用轮寻查找方式在波束查找表中确定目标波束，此方法简单，容易实现。
当驱动装置40用于驱动定向天线30绕第一轴线L1转动时，波束查找表中多个波束组成多个波束子集，该多个波束子集沿第一轴线L1的周向排列，波束子集至少包括指向与第一轴线L1垂直的第一波束a。在此基础上，请参阅图26，图26为图25所示确定目标波束的方法中步骤S410的一种方法流程图。步骤S410包括下面的步骤S411和步骤S412。
步骤S411：通过驱动装置40驱动定向天线30绕第一轴线L1转动，以使定向天线30的波束指向分别与多个波束子集中的第一波束a的指向重合，并在定向天线30的波束指向分别与多个波束子集中第一波束a的指向重合时，检测定向天线30接收到的来自第一目标设备的信号质量，以得到多个第三信号质量。其中，由于每个波束子集均包括第一波束a，因此，多个波束子集中的第一波束a是指多个第一波束a，该多个第一波束a分别属于该多个波束子集。
步骤S412：根据多个第三信号质量，确定目标波束子集，目标波束属于该目标波束子集。
在一些实施例中，步骤S412可以包括：根据多个第三信号质量，确定最优第三信号质量；根据最优第三信号质量，确定该最优第三信号质量对应的第一波束a所处的波束子集为目标波束子集。需要说明的是，最优第三信号质量对应的第一波束a是指当检测的第三信号质量为最优第三信号质量时，与定向天线30的波束指向重合的第一波束a。
这样一来，当定向天线30转动至波束指向与该多个第一波束a的指向重合时，可以覆盖XY平面内的目标设备，无线路由器可以适用于大平层房屋结构。
在上述实施例的基础上，当驱动装置40还用于驱动定向天线30绕第二轴线L2转动时,波束子集包括沿第二轴线L2的周向排列的多个波束，第一波束a为该多个波束中的一个。基于此，请参阅图27，图27为图25所示确定目标波束的方法中步骤S410 的又一种方法流程图。在步骤S412之后，步骤S410还包括下面的步骤S413。
步骤S413：通过驱动装置40驱动定向天线30绕第二轴线L2转动，以使定向天线30的波束指向分别与目标波束子集中多个波束的指向重合，并在定向天线30的波束指向分别与目标波束子集中多个波束的指向重合时，检测定向天线30接收到的来自第一目标设备的信号质量，以得到多个第四信号质量；
在上述实施例的基础上，请继续参阅图27，上述步骤S420包括下面的步骤S421。
步骤S421：根据多个第四信号质量，在目标波束子集中确定目标波束。
在一些实施例中，步骤S421可以包括：根据多个第四信号质量，确定最优第四信号质量；根据最优第四信号质量，确定该最优第四信号质量对应的波束为目标波束。需要说明的是，最优第四信号质量对应的波束是指当检测的第四信号质量为最优第四信号质量时，目标波束子集中，与定向天线30的波束指向重合的波束。
这样一来，波束查找表中的多个波束分布于XYZ三维空间范围内，通过定向天线30转动至波束指向与该XYZ三维空间范围内的多个波束的指向重合时，可以覆盖XYZ三维空间范围内的目标设备，无线路由器可以适用于别墅、复式楼等房屋结构。
请参阅图28，图28为图23或图24所示控制方法中又一种确定目标波束的方法流程图。在本实施例中，步骤S400包括下面的步骤S430和步骤S440。
步骤S430：获取第一目标设备的位置信息；
步骤S440：根据第一目标设备的位置信息，在波束查找表中确定目标波束。
这样一来，无线路由器无需轮寻查找目标波束，能够快速确定目标波束，响应较快，延迟时间较短。
在一些实施例中，步骤S440可以包括：根据第一目标设备的位置信息，在波束查找表中，确定波束指向与第一目标设备相对于无线路由器的位置方向之间的夹角最小的波束为目标波束。这样，定向天线30对第一目标设备的覆盖效果较优。
以上多个实施例所述的控制方法均是基于覆盖第一目标设备的目的实施，当目标设备的数量为多个时，可以根据目标设备的网络类型、设备类型和设备使用信息(包括但不限于使用时间和使用概率)，确定多个目标设备的优先级，无线路由器覆盖优先级最高的目标设备，以提高波束切换的合理性。
具体的，请参阅图29，图29为本申请又一些实施例提供的无线路由器的控制方法流程图。在步骤S100和步骤S200之前，控制方法还包括步骤S600和步骤S700。
步骤S600：根据多个目标设备的设备信息确定该多个目标设备的优先级。其中，目标设备的设备信息包括网络类型、设备类型、无线数据请求特性和设备使用信息中的至少一种，设备使用信息包括使用时间和使用概率中的至少一种。比如物联网(internet of things，iot)设备数据量小，在优先级上的排序可以靠后。又比如学生网课设备在某个时间段需要优先保证网络通畅，在该时间段内的优先级上的排序可以靠前。根据设备的统计规律，无线路由器经过一段时间的自主学习，识别出以下场景：哪些是iot设备，哪些是低延迟大数据量设备(比如高清智慧屏、网课设备、游戏设备)，哪些是边缘设备，哪些是位置固定设备等。根据设备出现的时间、概率等，了解用户使用习惯，实现多用户的优先级排序策略。
步骤S700：将多个目标设备中优先级最高的目标设备确定为第一目标设备。
在一些实施例中，在步骤S600之前，控制方法还包括：通过定向天线20和/或全向天线30轮寻识别目标设备，以得到多个目标设备。
