步骤S104、根据所述信道参数比较结果，确定所述可移动平台与所述终端设备进行通信的天线配置。
目前，为了保证无线图传的传输性能，可移动平台通常都是同时使用多个天线发射数据。然而，可移动平台同时使用多个天线发射数据比仅使用一个天线发射数据的功耗更高、发热更严重。由于功耗和发热量会随着传输时间的增加而增加，这将导致可移动平台的温度上升，影响可移动平台的运行，用户体验不好。因此，在可移动平台与终端设备进行通信的过程中，获取可移动平台仅通过第一天线与终端设备进行通信对应的第一信道参数，并获取可移动平台同时通过至少两个天线与终端设备通信对应的第二信道参数，然后将第一信道参数与第二信道参数进行比较，得到信道参数比较结果，并根据信道参数比较结果，确定可移动平台与终端设备进行通信的天线配置从而使得可移动平台能够自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。在一个实施方式中，所述至少两个天线包括所述第一天线。
由于可移动平台的电池的容量有限，并且可移动平台工作时的单位耗电量也较高，因此可移动平台的续航时间是有限的，通过本申请实施例提供的天线选择方法，在可移动平台工作的过程中，可以自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗，还可以提高可移动平台的续航时间，极大的提高了用户体验。
此外，由于可移动平台内部的电池、电机等器件对温度有一定的要求，如果电池或电机等器件的温度较高，则会影响电池或电机等器件的正常运行，进而导致可移动平台无法正常的工作，通过本申请实施例提供的天线选择方法，在可移动平台工作的过程中，可以自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗，由于减少了可移动平台的功耗，可以在一定程度上减少发热量，能够避免较高的发热量导致电池或电机等器件的温度快速上升，保证电池或电机等器件 的正常运行，提高可移动平台的安全性。
其中，至少两个天线位于可移动平台上，所述至少两个天线包括第一天线，所述第一信道参数用于指示仅通过第一天线与终端设备进行通信时的第一信道容量和/或第一信噪比，所述第二信道参数用于指示可移动平台同时通过至少两个天线与终端设备进行通信时的第二信道容量和/或第二信噪比。可移动平台仅通过第一天线与终端设备进行通信对应的第一信道参数的数值比可移动平台仅通过至少两个天线中的其他天线中的任意一根天线与终端设备进行通信对应的第三信道参数的数值大，也即可移动平台仅通过第一天线与终端设备进行通信对应的第一信道容量大于可移动平台仅通过至少两个天线中的其他天线中的任意一根天线与终端设备进行通信对应的第三信道容量，和/或，可移动平台仅通过第一天线与终端设备进行通信对应的第一信噪比大于可移动平台仅通过至少两个天线中的其他天线中的任意一根天线与终端设备进行通信对应的第三信噪比。
由于可移动平台仅通过第一天线与终端设备进行通信对应的第一信道参数的数值比可移动平台仅通过至少两个天线中的其他天线中的任意一根天线与终端设备进行通信对应的第三信道参数的数值大，因此，将第一信道参数与第二信道参数进行比较，可以知道，通过信道质量最好的第一天线与终端设备进行通信的传输性能与通过至少两个天线与终端设备进行通信的传输性能是否均满足当前需要的传输性能要求，不需要将仅通过每个天线与终端设备进行通信分别对应的信道参数与第二信道参数进行比较，减少计算量，提高处理速度。
在一实施例中，可移动平台包括第一工作模式和第二工作模式，第一工作模式对视频的清晰度/画质要求较高，第二工作模式对视频的清晰度/画质要求较低。因此，第一工作模式下的可移动平台与终端设备之间的数据量传输量大于第二工作模式下的可移动平台与终端设备之间的数据量传输量。同时，第一工作模式对传输的可靠性要求较低，第二工作模式对传输的可靠性要求较高，因此第一工作模式下的可移动平台与终端设备之间的误码率有时可能会大于第二工作模式下的可移动平台与终端设备之间的误码率。
在一实施例中，当可移动平台的当前工作模式为第一工作模式时，第一信道参数用于指示仅通过第一天线与终端设备进行通信时的第一信道容量，第二信道参数用于指示同时通过至少两个天线与终端设备进行通信时的第二信道容量，也即在可移动平台的当前工作模式为第一工作模式时，仅考虑信道容量对天线选择的影响，而不考虑信噪比对天线选择的影响。当可移动平台的当前工 作模式为第二工作模式时，所述第一信道参数用于指示仅通过第一天线与终端设备进行通信时的第一信噪比，第二信道参数用于指示同时通过至少两个天线与终端设备进行通信时的第二信噪比，也即在可移动平台的当前工作模式为第二工作模式时，仅考虑信噪比对天线选择的影响，而不考虑信道容量对天线选择的影响。通过在不同的工作模式下，考虑不同的信道参数对天线选择的影响，从而能够在满足不同工作模式的传输性能要求的情况下，减少可移动平台的功耗和发热量，提高用户体验。
在一实施例中，将第一信道参数与第二信道参数进行比较的方式可以为：确定第一信道参数与第二信道参数的差值，其中，第一信道参数与第二信道参数的差值包括第一信道容量与第二信道容量的差值，和/或，第一信噪比与第二信噪比的差值；或者确定第一信道参数乘以第一预设系数得到的乘积与第二信道参数之间的差值，其中，第一预设系数大于1；或者确定第二信道参数乘以第二预设系数得到的乘积与第一信道参数之间的差值，其中，第二预设系数小于1，且大于0；或者确定第一信道参数和第二信道参数是否位于预定范围内。其中，第一预设系数、第二预设系数和预定范围可基于实际情况进行设置，本申请实施例对此不做具体限定，例如，第一预设系数为
Figure PCTCN2020131939-appb-000001
第二预设系数为0.5。
在一实施例中，确定第一信道参数乘以第一预设系数得到的乘积与第二信道参数之间的差值的方式可以为：确定第一信道参数乘以第一预设系数得到的乘积，且将该乘积记为第一目标信道参数，然后确定第一目标信道参数与第二信道参数之间的差值。其中，第一目标信道参数包括第一目标信道容量和/或第一目标信噪比，第一目标信道参数与第二信道参数之间的差值包括第一目标信道容量与第二信道容量的差值，和/或，第一目标信噪比与第二信噪比的差值。
在一实施例中，确定第二信道参数乘以第二预设系数得到的乘积与第一信道参数之间的差值的方式可以为：确定第二信道参数乘以第二预设系数得到的乘积，且将乘积记为第二目标信道参数，然后确定第二目标信道参数与第一信道参数之间的差值。其中，第二目标信道参数包括第二目标信道容量和/或第二目标信噪比，第二目标信道参数与第一信道参数之间的差值包括第二目标信道容量与第一信道容量的差值，和/或，第二目标信噪比与第一信噪比的差值。
在一实施例中，如图3所示，步骤S104可以包括子步骤S1041至S1042。
子步骤S1041、确定所述信道参数比较结果是否满足预设条件。
在得到信道参数比较结果后，确定该信道参数比较结果是否满足预设条件， 如果该信道参数比较结果满足预设条件，则可以确定可移动平台仅通过第一天线与终端设备进行通信的传输性能和同时通过至少两个天线与终端设备进行通信的传输性能均满足当前需要的传输性能要求，如果该信道参数比较结果不满足预设条件，则可以确定可移动平台仅通过第一天线与终端设备进行通信的传输性能不满足当前需要的传输性能要求。
其中，所述预设条件包括：第一信道参数与第二信道参数均位于预定范围。或者，第一信道参数与第二信道参数的差值的绝对值小于或等于预设值，其中，第一信道参数与第二信道参数的差值的绝对值小于或等于预设值包括第一信道容量与第二信道容量的差值小于或等于预设信道容量差值，和/或，第一信噪比与第二信噪比的差值小于或等于预设信噪比差值。
或者，第一信道参数乘以第一预设系数得到的乘积与第二信道参数之间的差值的绝对值小于或等于预设值，第一预设系数大于1，其中，第一信道参数乘以第一预设系数得到的乘积与第二信道参数之间的差值的绝对值小于或等于预设值包括第一目标信道容量与第二信道容量的差值小于或等于预设信道容量差值，和/或，第一目标信噪比与第二信噪比的差值小于或等于预设信噪比差值。
或者，第二信道参数乘以第二预设系数得到的乘积与第一信道参数之间的差值的绝对值小于或等于预设值，第二预设系数小于1，且大于0，其中，第二目标信道容量与第一信道容量的差值小于或等于预设信道容量差值，和/或，第二目标信噪比与第一信噪比的差值小于或等于预设信噪比差值。
子步骤S1042、若所述信道参数比较结果满足预设条件，则仅将所述第一天线作为目标天线，以使得所述可移动平台通过所述目标天线与所述终端设备通信。
在信道参数比较结果满足预设条件，也即可移动平台仅通过第一天线与终端设备进行通信的传输性能和同时通过至少两个天线与终端设备进行通信的传输性能均满足当前需要的传输性能要求时，将第一天线作为目标天线，以使得可移动平台通过目标天线与终端设备通信，从而能够在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
在一实施例中，若信道参数比较结果满足预设条件，则在可移动平台的温度大于或等于预设温度时，将第一天线作为目标天线，以使得可移动平台通过目标天线与终端设备通信。其中，可移动平台的温度可以通过可移动平台上的温度传感器采集确定，预设温度可基于实际情况进行设置，本申请实施例对此不做具体限定。通过在可移动平台的温度大于或等于预设温度时，可移动平台 仅通过第一天线与终端设备通信，可以减少可移动平台的功耗和发热量，防止可移动平台的温度过高导致可移动平台损坏，提高用户体验。
在一实施例中，若信道参数比较结果不满足预设条件，也即可移动平台仅通过第一天线与终端设备进行通信的传输性能不满足当前需要的传输性能要求，而通过至少两个天线与终端设备进行通信的传输性能满足当前需要的传输性能要求，则将至少两个天线作为目标天线，以使得可移动平台通过目标天线与终端设备通信。通过在可移动平台仅通过第一天线与终端设备进行通信的传输性能不满足当前需要的传输性能要求，而通过至少两个天线与终端设备进行通信的传输性能满足当前需要的传输性能要求时，可移动平台通过至少两个天线与终端设备通信，保证无线图传的传输性能。
在一实施例中，将第一天线作为目标天线后，也即可移动平台仅通过第一天线与终端设备进行通信的过程中，控制至少两个天线中除该目标天线(第一天线)之外的天线对应的功率放大器和射频收发器处于关闭状态。或者，控制至少两个天线中除目标天线(第一天线)之外的天线对应的功率放大器处于关闭状态；控制至少两个天线中除目标天线(第一天线)之外的天线对应的发射通道处于关闭状态。通过关闭其余没有工作的天线对应的功率放大器和射频收发器，或者关闭其余没有工作的天线对应的功率放大器和发射通道，可以降低可移动平台的功耗和发热量。
其中，对于多天线使用多射频收发器的场景，也即天线与射频收发器一一对应的场景，可以通过关闭其余没有工作的天线对应的功率放大器和射频收发器来降低可移动平台的功耗和发热量，而对于多天线使用一个射频收发器的场景，该射频收发器包括多个发射通道，因此，可以通过关闭其余没有工作的天线对应的功率放大器和射频收发器中的发射通道来降低可移动平台的功耗和发热量。
上述实施例提供的天线选择方法，通过获取可移动平台仅通过第一天线与终端设备进行通信对应的第一信道参数，以及获取可移动平台同时通过至少两个天线与终端设备通信对应的第二信道参数，然后将第一信道参数与第二信道参数进行比较，得到信道参数比较结果，并根据信道参数比较结果，确定可移动平台与终端设备进行通信的天线配置，从而使得可移动平台能够自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
请参阅图4，图4是本申请实施例提供的另一种天线选择方法的步骤示意 流程图。该天线选择方法可以应用在终端设备或无人机中，用于自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。

步骤S204、根据所述多个信道参数比较结果，确定所述可移动平台与所述终端设备进行通信的天线配置。
目前，为了保证无线图传的传输性能，可移动平台通常都是同时使用多个天线发射数据。然而，可移动平台同时使用多个天线发射数据比仅使用一个天线发射数据的功耗更高、发热更严重。由于功耗和发热量会随着传输时间的增加而增加，这将导致可移动平台的温度上升，影响可移动平台的运行，用户体验不好。
因此，在可移动平台与终端设备进行通信的过程中，获取可移动平台仅通过至少两个天线中的任一个天线与终端设备进行通信对应的第一信道参数，以及获取可移动平台同时通过至少两个天线与终端设备通信对应的第二信道参数，然后将任一个天线与终端设备进行通信对应的第一信道参数分别与第二信道参数进行比较，得到多个信道参数比较结果，最后根据多个信道参数比较结果，确定可移动平台与终端设备进行通信的天线配置，从而使得可移动平台能够自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
在一实施例中，如图5所示，步骤S204可以包括：子步骤S2041至S2042。
S2041、确定所述多个信道参数比较结果中是否存在至少一个信道参数比较结果满足预设条件。
在获取到多个信道参数比较结果后，确定多个信道参数比较结果中是否存在至少一个信道参数比较结果满足预设条件，若存在至少一个信道参数比较结果满足预设条件，则可以确定仅通过单天线与终端设备进行通信的传输性能和同时通过至少两个天线与终端设备进行通信的传输性能满足当前需求的传输性 能要求，则多个信道参数比较结果均不满足预设条件，则可以确定仅通过单天线与终端设备进行通信的传输性能不满足当前需求的传输性能要求。

S2042、若存在至少一个信道参数比较结果满足预设条件，则根据满足预设条件的至少一个所述第一信道参数从所述至少两个天线中选择一个天线作为目标天线。
若多个信道参数比较结果中存在至少一个信道参数比较结果满足预设条件，则仅通过单天线与终端设备进行通信的传输性能和同时通过至少两个天线与终端设备进行通信的传输性能满足当前需求的传输性能要求，则根据满足预设条件的至少一个第一信道参数从至少两个天线中选择一个天线作为目标天线，以使得可移动平台通过目标天线与终端设备进行通信，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
在一实施例中，根据满足预设条件的至少一个第一信道参数从至少两个天线中选择一个天线作为目标天线的方式可以为：将满足预设条件的至少一个第一信道参数中的最大的第一信道参数确定为目标信道参数；将至少两个天线中与目标信道参数对应的天线作为目标天线，以使得可移动平台通过目标天线与终端设备通信。可移动平台通过传输性能最好的天线与终端设备进行通信，可以提高无线图传的传输性能，也能够在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
在一实施例中，目标信道参数包括目标信道容量和目标信噪比，将至少两个天线中与目标信道参数对应的天线作为目标天线的方式可以为：在可移动平台处于第一工作模式时，将至少两个天线中与目标信道容量对应的天线作为目标天线；在可移动平台处于第二工作模式时，将至少两个天线中与目标信噪比对应的天线作为目标天线。通过在不同的工作模式下，考虑不同的信道参数对天线选择的影响，从而能够在满足不同工作模式的传输性能要求的情况下，减少可移动平台的功耗和发热量，提高用户体验。
其中，第一工作模式对视频的清晰度/画质要求较高，因此，第二工作模式对视频的清晰度/画质要求较低，所述第一工作模式下的可移动平台与终端设备之间的数据量传输量大于第二工作模式下的可移动平台与终端设备之间的数据量传输量。同时，第一工作模式对传输的可靠性要求较低，第二工作模式对传输的可靠性要求较高，因此第一工作模式下的可移动平台与终端设备之间的误码率大于第二工作模式下的可移动平台与终端设备之间的误码率。
在一实施例中，若多个信道参数比较结果均不满足预设条件，即仅通过单天线与终端设备进行通信的传输性能不满足当前需求的传输性能要求，则将至少两个天线作为目标天线，以使得可移动平台通过目标天线与所述终端设备通信。通过在可移动平台仅通过单天线与终端设备进行通信的传输性能不满足当前需要的传输性能要求，而通过至少两个天线与终端设备进行通信的传输性能满足当前需要的传输性能要求时，可移动平台通过至少两个天线与终端设备通信，保证无线图传的传输性能。
在一实施例中，若存在至少一个信道参数比较结果满足预设条件，则在可移动平台的温度大于或等于预设温度时，根据满足预设条件的至少一个第一信道参数从至少两个天线中选择一个天线作为目标天线；在可移动平台的温度小于预设温度时，将至少两个天线作为目标天线，以使得可移动平台通过目标天线与终端设备通信。其中，可移动平台的温度可以通过可移动平台上的温度传感器采集确定，预设温度可基于实际情况进行设置，本申请实施例对此不做具体限定。通过在可移动平台的温度大于或等于预设温度时，可移动平台仅通过单天线与终端设备通信，可以减少可移动平台的功耗和发热量，防止可移动平台的温度过高导致可移动平台损坏，提高用户体验。
上述实施例提供的天线选择方法，获取可移动平台仅通过至少两个天线中的任一个天线与终端设备进行通信对应的第一信道参数，以及获取可移动平台同时通过至少两个天线与终端设备通信对应的第二信道参数，然后将任一个天线与终端设备进行通信对应的第一信道参数分别与第二信道参数进行比较，得到多个信道参数比较结果，最后根据多个信道参数比较结果，确定可移动平台与终端设备进行通信的天线配置，从而使得可移动平台能够自适应的选择可移动平台与终端设备进行通信的天线配置，进而在保证无线图传的传输性能的同时，减少可移动平台的功耗和发热量，提高用户体验。
