具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
请参见图1，图1是本申请实施例提供的一种电磁辐射控制系统的结构示意图。如图所示，本申请实施例中的系统包括用户设备和用户。其中，用户设备可以是任意一种具有无线收发功能的设备，可以是指提供到用户的语音和/或数据连接的设备，也可以被连接到诸如膝上型计算机或台式计算机等的计算设备，或者可以是诸如个人数字助理(personal digital assistant，PDA)等的独立设备。用户设备还可以称为系统、用户单元、用户站、移动站、移动台、远程站、接入点、远程终端、接入终端、用户终端、用户代理或用户装置。用户设备可以是产生第五代移动通信技术的(5-generation，5G)毫米波的器件，比如，笔记本，路由器，手表等等。用户设备中可以包括测距传感器，通过测距传感器测量用户与用户设备之间的间隔距离。基于上述系统，本申请实施例提供了如下解决方案。
请参见图2，图2是本申请实施例提供的一种电磁辐射控制方法的流程示意图，该方法包括但不限于如下步骤：
S201，获取用户设备与用户之间的间隔距离。
具体实现中，测距传感器可以包括激光测距传感器、红外测距传感器、超声波测距传感器、毫米波测距传感器等等，可以通过激光测距传感器、红外测距传感器、超声波测距传感器或毫米波测距传感器测量所述用户设备与所述用户之间的所述间隔距离。其中，测距传感器可以设置在用户设备内部，也可以将测距传感器放置在用户设备上使用。例如，可以通过用户设备内部设置的激光测距传感器，向用户发射激光信号并记录发射激光信号的时间点，激光信号经过人体反射后，返回到激光测距传感器，此时记录接收到激光信号的时间点，根据发射激光信号的时间点和接收到激光信号的时间点，确定激光信号的传输时长，进而根据传输时长确定用户设备与用户之间的间隔距离。或者，可以通过红外测距传感器发射红外信号，由于间隔距离的不同接收到的反射回来的红外信号的强度也不同的原理，来测量用户设备与用户之间的间隔距离。还可以通过其他多种方法来测量用户设备与用户之间的间隔距离，此处不再赘述。
其中，由于电磁辐射对用户的影响程度、与用户设备与用户之间的间隔距离相关，间隔距离越近，电磁辐射对用户的影响程度越大，间隔距离越远，电磁辐射对用户的影响程度越小，当间隔距离超过预设距离范围时，电磁辐射对用户的影响程度几乎为0。因此可以在预设距离范围内，通过测距传感器测量所述用户设备与所述用户之间的所述间隔距离。预设距离范围可以为电磁辐射对用户存在影响的距离，如20cm。在预设距离范围内，需要将用户设备发射的毫米波产生的电磁辐射控制在最大允许辐射量的范围内。
可选的，可以按照预设周期测量所述用户设备与所述用户之间的所述间隔距离，并将每次测量的间隔距离上报给用户设备的核心处理器进行处理。其中，预设周期可以为1秒或2秒等等。
可选的，可以获取经过多次测量得到的所述用户设备与所述用户之间的多个测量距离；
将所述多个测量距离的平均值作为所述间隔距离。
S202，根据所述间隔距离，调整所述用户设备发射的毫米波的等效通向辐射功率，使得发射的所述毫米波产生的电磁辐射满足最大允许辐射量。其中，毫米波为波长为1～10毫米的电磁波，具有带宽高、波束窄的特点。等效通向辐射功率为在某个指定方向上的辐射功率，理想情况下等于功放的发射功率乘以天线的增益。
具体实现中，在发射的所述毫米波产生的电磁辐射满足最大允许辐射量的前提下，当间隔距离变大时，可以提高用户设备发射的毫米波的等效通向辐射功率，从而提高毫米波的发射效率。当间隔距离变小时，可以降低用户设备发射的毫米波的等效通向辐射功率，保障用户不受电磁辐射的影响。
进一步的，可以从预设的目标校准表中查找与所述间隔距离对应的功率值，其中，所述目标校准表包括所述间隔距离与所述功率值的对应关系；将所述用户设备发射的所述毫米波的所述等效通向辐射功率调整到所述功率值，从而保障在该间隔距离下用户设备产生的电磁辐射不会对用户产生影响。例如，如图3所示，图3是本申请实施例提供的一种校准表的示意图，该校准表为满足最大允许辐射量要求下的EIRP和间隔距离的校准表。当用户与用户设备的间隔距离为D-0时，可以将用户设备发射的毫米波的等效通 向辐射功率调整到EIRP-1，保证在D-0范围内用户设备发射的毫米波产生的电磁辐射不会对用户产生影响。当用户与用户设备的间隔距离为D-3时，可以将用户设备发射的毫米波的等效通向辐射功率调整到EIRP-3，保证在D-3范围内用户设备发射的毫米波产生的电磁辐射不会对用户产生影响。
另外，在对所述用户设备发射的毫米波的等效通向辐射功率调整之前，可以预先配置上述EIRP和间隔距离的校准表，以便在调整等效通向辐射功率时使用。具体包括：将测距传感器放置在用户设备的正面、反面及边框，全面覆盖用户设备发射毫米波所使用的天线的辐射空间，通过测距传感器测量用户设备与用户之间的距离，并测量当前的电磁辐射大小，在电磁辐射大小满足最大允许辐射量时，记录此时用户设备发射的毫米波的等效通向辐射功率。然后，改变用户设备与用户之间的距离，按照上述方法进行多次测试，可以生成EIRP和间隔距离的校准表。
可选的，由于在5G应用中发射毫米波所使用的天线会根据网络环境的变化而变换，天线的不同，其产生的电磁辐射也是不相同的。因此，可以预先配置用户终端的所有天线中每个天线对应的校准表。在实际应用的网络环境中，可以首先获取所述用户设备的多个天线中每个天线的接收信号强度；根据所述接收信号强度，确定所述用户设备发射所述毫米波所使用的天线，例如可以将接收信号强度最高的天线作为发射所述毫米波所使用的天线、或者接收信号强度大于预设阈值的天线作为发射所述毫米波所使用的天线。然后根据所述发射所述毫米波所使用的天线，从预设的多个校准表中选取所述目标校准表，从而实现调整等效通向辐射功率的精确性。
在本申请实施例中，首先获取用户设备与用户之间的间隔距离；然后根据所述间隔距离，调整所述用户设备发射的毫米波的等效通向辐射功率，使得发射的所述毫米波产生的电磁辐射满足最大允许辐射量。通过按照用户设备与用户之间不同的间隔距离，调整发射的毫米波的等效通向辐射功率，从而在保障用户安全的前提下，提高毫米波的发射功率和发射效率。
