在有遥控器到飞行器的大数据量通信需求时，现有通信系统的宽带设计不能满足其通信要求。比如，在使用终端软件升级飞行器系统固件的时候，终端软件一般和遥控器相连，并通过遥控器将升级固件发送给飞行器。而受限于遥控器到飞行器的通信带宽，该升级固件的传输时间较长，故导致飞行器的升级过程缓慢。
因此，现有的飞行器通信系统设计无法满足其数据传输需求。

【具体实施方式】
下面结合说明书附图，对本申请实施例的方案进行详细说明。
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。
为便于理解，先对本申请部分用语进行说明。在本申请中，所述上行链路为：无线通信系统中的外部设备向飞行器发送数据的通信链路；所述下行链路：无线通信系统中的飞行器向外部设备发送数据的通信链路；所述固件：加载到并存储在硬件上的可执行文件，用于控制硬件实现特定的功能。
请参阅图1，图1是本申请无线通信系统一实施例的结构示意图。本申请中，该无线通信系统10包括飞行器11、遥控器12和上位设备13。
上位设备13具体如电脑、手机等任意可与遥控器12通信的设备。该上位设备与该遥控器12有线或无线连接。例如，该上位设备13通过USB或UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输器)与遥控器12实现有线通信。
该上位设备13用于与遥控器12交互与该飞行器11相关的数据，具体如向遥控器12发送关于飞行器11的相关控制指令或者飞行器11的升级固件等，以及接收遥控器12发送的关于飞行器11的信息，例如飞行器11的当前状态、航线以及飞行器采集到的数据等。
遥控器12作为本申请所述外部设备与飞行器11通过无线通信链路进行通信。具体，该遥控器12用于向飞行器11发送控制指令(该控制指令可以来源于上位设备13或者由检测到用户对遥控器12的操作而产生的)或者上位设备13发送的升级固件等，以及还可接收该飞行器11返回的与该控制指令或升级固件相关的反馈信息、飞行器11的当前状态、航线及采集数据等。本实施例中，遥控器12具体包括与上位设备13通信的第一通信子系统、与飞行器11通信的第二通信子系统以及遥控杆量测子系统等。
飞行器11用于接收遥控器12的控制指令而执行相关飞行或检测，并可接收遥控器12发送的升级固件进行升级，以及向遥控器12返回数据。本实施例中，该飞行器11包括与遥控器通信的第三通信子系统、飞行控制子系统以及采集子系统等。该飞行控制子系统用于根据遥控器12发送的指令实现控制飞行器11飞行；该采集子系统可包括相机、高度采集器等，对 应地，该飞行器11向遥控器12返回的采集数据可包括图像数据、历史飞行的高度数据等。在一具体应用中，上述子系统均为相应的电路。
可以理解的是，在其他实施例中，无线通信系统的外部设备可不为遥控器，而为其他控制设备，例如为与该飞行器无线连接的平板电脑、手机、VR眼镜、手环等。而且，该无线通信系统未必包括上述的上位设备，例如其仅包括飞行器和外部设备。进一步地，该系统中的飞行器可为多台，该多台飞行器可均由同一外部设备进行控制，当然，系统中的外部设备也可为多台，如该多台飞行器至少部分分别由不同外部设备控制。
在上述无线通信系统中，在外部设备与飞行器之间的上行链路的设定带宽较小，但遇到外部设备需向飞行器发送较大数据如发送升级固件时，该小带宽的上行链路则难以满足数据传输需求，故本申请提出将该上行链路的带宽根据数据传输请求进行调整。具体参阅下述方法实施例。
请参阅图2，图2是本申请无线通信方法一实施例的流程示意图。本实施例中，该方法由上述无线通信系统的飞行器执行，用于根据数据传输请求适应性调整链路带宽。该方法包括：
21：接收数据传输请求。
22：根据所述数据传输请求增加上行链路的传输带宽。
例如，飞行器接收到外部设备发送的数据传输请求。该数据传输请求可包括待传输数据的大小和/或类型等，由此飞行器确定待传输数据的大小，并根据该待传输数据的大小增加上行链路的传输带宽。具体，飞行器判断该待传输数据是否大于设定数据量，若大于，则确定需实质增加其上行链路带宽，也即带宽的增加量大于零；否则确定上行链路的设定带宽可满足该数据需求，无需实质增加其上行链路带宽，也即带宽的增加量为零。
本实施例中，该外部设备与飞行器的通信电路(如上系统实施中的第二通信子系统和第三通信子系统)分别用于运行相应软件定义无线电(Software Defined Radio，SDR)固件以建立通信链路。即，该外部设备的通信电路通过运行其存储的SDR固件建立外部设备对应飞行器的收发链路，飞行器的通信电路通过运行其存储的SDR固件建立飞行器对应外部设备的收发链路。其中，该外部设备的接收链路、飞行器的发送链路即为上述的下行链路；外部设备的发送链路、飞行器的接收链路即为上述的上行链路。
本实施例中，由于上行链路的设定带宽小于下行链路的设定带宽，该设定带宽即为该链路的默认带宽。故，飞行器具体通过将上行链路和下行链路的带宽进行调换，以实质增加其上行链路带宽。
例如，飞行器中存储有两个SDR固件，其中，飞行器SDR固件用于建立飞行器的收发链路，外部设备SDR固件用于建立外部设备的收发链路，该建立飞行器和外部设备的收发链路是指建立具有其设定带宽的收发链路。本22具体包括：停止向飞行器的通信电路加载飞行器SDR固件，并将内置的外部设备SDR固件加载至飞行器的通信电路中。此时，飞行器的通信电路将建立外部设备的默认收发链路作为其新的收发链路，外部设备同时也将建立飞行器的默认收发链路作为其新的收发链路，如此，实现原本上下行链路的带宽调换，上行链路的带宽变大。
又例如，飞行器中存在的SDR固件中包含建立飞行器的默认收发链路的飞行器部分和建立外部设备的默认收发链路的外部设备部分。本22具体包括：将所述飞行器的通信电路从飞行器模式切换至外部设备模式，即飞行器的通信电路从原本运行上述SDR固件的飞行器部分更换为运行上述SDR固件的外部设备部分。其中，所述飞行器模式用于建立所述飞行器的收发链路，所述外部设备模式用于建立所述外部设备的收发链路，该建立飞行器和外部设备的收发链路是指建立具有其设定带宽的收发链路。此时，飞行器的通信电路将建立外部设备的默认收发链路作为其新的收发链路，外部设备同时也将建立飞行器的默认收发链路作为其新的收发链路，如此，实现原本上下行链路的带宽调换，上行链路的带宽变大。
23：从所述上行链路中接收待传输数据。
外部设备从该上行链路中将待传输数据传输至飞行器，当上行链路的带宽变大，其数据传输速度将得到提升。在一具体应用中，该待传输数据为飞行器的固件，固件用于升级所述飞行器。飞行器接收到固件后，在其待机时或者即时运行该固件进行升级。
本实施例中，在上行链路需传输数据时，飞行器和外部设备根据该传输数据请求增加上行链路的传输带宽，故实现对飞行器与外部设备间的上行链路带宽的灵活调整，以满足其数据传输需求。
在另一实施例中，上述23中飞行器从上行链路接收完毕待传输数据后， 将上行链路的通信带宽恢复至设定带宽(默认带宽)。
对应上述22的两个例子进行举例：例如，飞行器停止向飞行器的通信电路加载所述外部设备SDR固件；将飞行器SDR固件加载至飞行器的通信电路；又例如，将所述飞行器的通信电路从外部设备模式切换至飞行器模式，即飞行器的通信电路从原本运行上述SDR固件的外部设备部分更换为运行上述SDR固件的飞行器部分。此时，飞行器的通信电路将重新建立起飞行器的默认收发链路，外部设备同时也将重新建立起外部设备的默认收发链路，如此，实现上下行链路的带宽恢复原来设定。然后，飞行器再对该待传输数据进行处理如执行升级。当然，也可在数据处理后进行上述链路带宽的恢复。
当该待传输数据传输完毕后，将其上下行链路带宽恢复原来设定，可避免对下行链路的数据传输的影响，故不影响飞行器和外部设备的正常使用。当然，在其他实施例中，可在下行链路需要进行数据传输时，或者判断上行链路后续需传输的数据小于设定数据量时，再执行上述上下行链路的带宽恢复。
请参阅图3，图3是本申请无线通信方法另一实施例的流程示意图。实施例中，该方法由上述无线通信系统的外部设备执行，用于根据数据传输请求适应性调整链路带宽。该方法包括：
31：发送数据传输请求。
32：根据所述数据传输请求增加上行链路的传输带宽。
例如，外部设备通过上行链路向飞行器发送数据传输请求，以请求传输待传输数据。类似于上述飞行器通信方法实施例，外部设备根据该数据传输请求对应的待传输数据的大小增加上行链路的传输带宽。具体如，外部设备判断该待传输数据是否大于设定数据量，若大于，则确定需实质增加其上行链路带宽，也即带宽的增加量大于零；否则确定上行链路的设定带宽可满足该数据需求，无需实质增加其上行链路带宽，也即带宽的增加量为零。
本实施例中，该外部设备与飞行器的通信电路分别用于运行相应SDR固件以建立通信链路。由于上行链路的设定带宽小于下行链路的设定带宽，该设定带宽即为该链路的默认带宽。故，外部设备具体通过将上行链路和 下行链路的带宽进行调换，以实质增加其上行链路带宽。
例如，外部设备中存储有两个SDR固件，其中，飞行器SDR固件用于建立飞行器的收发链路，外部设备SDR固件用于建立外部设备的收发链路，该建立飞行器和外部设备的收发链路是指建立具有其设定带宽的收发链路。本32具体包括：停止向外部设备的通信电路加载外部设备SDR固件，并将内置的飞行器SDR固件加载至外部设备的通信电路中。此时，外部设备的通信电路将建立飞行器的默认收发链路作为其新的收发链路，如上实施例飞行器同时也将建立外部设备的默认收发链路作为其新的收发链路，如此，实现原本上下行链路的带宽调换，上行链路的带宽变大。
又例如，外部设备中存在的SDR固件中包含建立飞行器的默认收发链路的飞行器部分和建立外部设备的默认收发链路的外部设备部分。本32具体包括：将外部设备的通信电路从外部设备模式切换至飞行器模式，即外部设备的通信电路从原本运行上述SDR固件的外部设备部分更换为运行上述SDR固件的飞行器部分。其中，所述飞行器模式用于建立所述飞行器的收发链路，所述外部设备模式用于建立所述外部设备的收发链路，该建立飞行器和外部设备的收发链路是指建立具有其设定带宽的收发链路。此时，外部设备的通信电路将建立飞行器的默认收发链路作为其新的收发链路，飞行器同时也将建立外部设备的默认收发链路作为其新的收发链路，如此，实现原本上下行链路的带宽调换，上行链路的带宽变大。
33：从所述上行链路中发送待传输数据。
外部设备从该上行链路中将待传输数据传输至飞行器，当上行链路的带宽变大，其数据传输速度将得到提升。在一具体应用中，该待传输数据为飞行器的固件，固件用于升级所述飞行器。飞行器接收到固件后，在其待机时或者即时运行该固件进行升级。
本实施例中，在上行链路需传输数据时，飞行器和外部设备根据该传输数据请求增加上行链路的传输带宽，故实现对飞行器与外部设备间的上行链路带宽的灵活调整，以满足其数据传输需求。
在另一实施例中，上述33后，外部设备从上行链路发送完毕待传输数据后，将上行链路的通信带宽恢复至设定带宽(默认带宽)。
对应上述32的两个例子进行举例：例如，外部设备停止向外部设备的 通信电路加载飞行器SDR固件；将外部设备SDR固件加载至外部设备的通信电路；又例如，将外部设备的通信电路从飞行器模式切换至外部设备模式，即外部设备的通信电路从原本运行上述SDR固件的飞行器部分更换为运行上述SDR固件的外部设备部分。此时，外部设备的通信电路将重新建立起外部设备的默认收发链路，如上实施例飞行器同时也将重新建立起飞行器的默认收发链路，如此，实现上下行链路的带宽恢复原来设定。
当该待传输数据传输完毕后，将其上下行链路带宽恢复原来设定，可避免对下行链路的数据传输的影响。当然，在其他实施例中，可在下行链路需要进行数据传输时，或者判断上行链路后续需传输的数据小于设定数据量时，再执行上述上下行链路的带宽恢复。
可以理解的是，在以上方法实施例中，本申请增加上行链路带宽的方法不限定为上述上下行链路的带宽互换方式，在其他实施例中，还可采用其他方式如增加上行链路的带宽，例如直接将下行链路也更换为上行链路，实现双上行链路同时传输，或者其他扩展上行链路的方式。
请参阅图4，图4是本申请无线通信装置一实施例的结构示意图。本实施例中，该无线通信装置用于上述飞行器中，该无线通信装置包括第一接收模块41、带宽调整模块42和第二接收模块43。
