具体实施方式
本申请实施例提供了一种数据传输方法及相关装置,以实现无人机控制的可靠性。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
首先,对本申请的一种数据传输方法进行介绍。
参见图1,其示出了本申请一种数据传输方法一个实施例的流程示意图,本实施例的方法可以包括:
101,无人机的控制器接收发送端发送的目标数据。
其中,发送端为地面控制装置或者无人机的机载设备。
本实施例所描述的机载设备无人机外设的机载设备,即,该机载设备通过无人机的通用接口与该无人机相连,通用接口用于连接不同类型的机载设备。如,该机载设备可以是通过无人机的通用接口与无人机相连的传感器,例如,图像传感器、温度传感器等。
地面控制装置可以理解为能够控制无人机的地面装置,地面控制装置可以向无人机发送控制数据或者控制指令,来对无人机进行控制。如,地面控制装置可以为移动终端,也可以是地面站的遥控器等控制装置。
102,将该目标数据转发给接收端。
其中,接收端为地面控制装置或者通过无人机的通用接口与无人机相连的 机载设备,且该接收端不同于该发送端。如,发送端为机载设备时,接收端可以为地面控制装置。
可以理解的是,地面控制装置可以与无人机的控制器进行数据通信,而通过无人机的通用接口与无人机相连的机载设备也可以与无人机的控制器进行数据通信,因此,通过无人机的控制器可以实现机载设备与地面控制装置的数据互传。基于此,控制器在接收到机载设备或地面控制装置作为发送端发送的目标数据后,会将该目标数据转发给相应的接收端。如,当发送端为机载设备时,则控制器接收到机载设备发送的目标数据后,可以将该机载设备发送的目标数据传输给作为接收端的该地面控制装置。相应的,当发送端为地面控制装置时,则控制器接收到地面控制装置发送的目标数据后,会将该目标数据转发给作为接收端的机载设备。
可见,在本申请实施例中,通过无人机的控制器可以实现无人机的机载设备与无人机的地面控制装置之间的数据互传,这样,地面控制装置可以获取到机载设备发出的数据,以及时了解到机载设备对无人机的控制情况或者是无人机的运行状态信息,从而可以及时发现机载设备的故障,进而可以更为可靠的控制无人机的运行;同时,地面控制装置也可以通过无人机的控制器向机载设备发送数据,以使得地面控制装置可以通过向机载设备发送数据,来对机载设备进行配置或者进行相关控制,以保证机载设备的可靠运行,从而有利于更为可靠的控制无人机。
可以理解的是,为了提高无人机与发送端数据传输的安全性以及可靠性,在发送端向无人机的控制器发送目标数据之前,该发送端可以向无人机发送数据转发请求,则控制器接收到该数据转发请求,并响应于该数据转发请求,建立该发送端与控制器之间的数据传输通道。则发送端可以通过该数据传输通道发送数据,从而控制器可以接收到发送端通过该数据传输通道传输的目标输数据。
其中,为了通过无人机的控制器实现对机载设备与地面控制装置之间的数据转发,该无人机的控制器中可以预置相应的控制程序,则在机载设备或地面控制装置需要向作为接收端的另一方发送数据之前,可以向控制器发送数据转 发请求,以调用该控制程序开放的接口,使得无人机运行该控制程序,当无人机的控制器通过该接口接收到发送端发送的目标数据后,便将该目标数据转发给接收端。
进一步的,控制器与接收端也可以建立有通信链路。
可选的,在控制器将目标数据转发给接收端之前,控制器可以接收该接收端发送的数据转发请求,控制器响应于该数据转发请求,建立控制器与接收端之间的通信链路。这样,控制器可以通过该通信链路,将接收到的目标数据转发给接收端。
与发送端向控制器发送数据转发请求相似,接收端向控制器发送数据转发请求也可以理解为该接收端调用该控制器中预置的控制程序开放的接口,以使得控制器运行该控制程序,以便在接收到发送端发送的目标数据后,将该目标数据转发给该接收端。
可选的,在以上任意一个实施例中,为了便于控制器识别出该目标数据为需要进行转发的数据,则发送端发送的目标数据可以为指定协议格式的数据。相应的,当控制器识别出接收到的目标数据为指定协议格式的数据时,则将该目标数据转发给该接收端。
在以上任意一个实施例中,接收端与发送端不同时,无人机的控制器接收到的目标数据也可能会有所不同,且控制器与接收端以及发送端的数据转发过程也可能会有所不同。
在一种可能的实现方式中,该发送端可以为机载设备,机载设备是指通过无人机的通用接口与无人机相连的机载设备。则,接收端则可以为地面控制装置。
在该种可能的实现方式中,发送端向控制器发送的需要转发的目标数据可以是机载设备感应到的数据,如传感器采集到的图像信息;也可以是机载设备对控制器的控制数据等。
可选的,为了能够了解到机载设备的运行状态,以及时了解到机载设备端 出现的故障或者控制异常,则机载设备向无人机的控制器发送的目标数据可以为状态数据,该状态数据用于表征该机载设备当前的运行状态。相应的,控制器在接收到机载设备发送的状态数据之后,会将该状态数据转发给地面控制装置。
可以理解的是,机载设备中可以预置开发人员编写的无人机控制程序,这样将给机载设备挂载到无人机之后,机载设备可以基于该无人机控制程序对无人机进行控制,如,机载设备可以通过串行总线与无人机的控制器进行数据通信,以对无人机进行控制。而机载设备的运行状态则可以体现出机载设备对无人机的控制状态,如,机载设备是否能稳定的控制无人机,以及机载设备是否出现程序运行异常,机载设备是否存在设备故障等等,这样,地面控制装置获取到该状态数据后,可以基于状态数据对机载设备的运行情况进行分析,如果分析出机载设备出现故障,则可以及时向机载设备发送控制数据,或者是及时切换到地面控制装置对无人机进行控制的模式。
可选的,在将目标数据转发给地面控制装置之前,还可以:获取目标数据的接收端标识。如,在目标数据中可以包括接收端标识;又如,机载设备可以发送目标数据的同时,发送接收端标识。根据该接收端标识,控制器可以将目标数据转发给该接收端标识所指向的地面控制装置。基于接收端标识确定接收目标输数据的地面控制装置的方式,可以在存在多个地面控制装置的情况下,准确确定需要接收该目标数据的地面控制装置。
可以理解的是,在发送端为机载设备的情况下,在机载设备在向无人机的控制器发送目标数据之前,机载设备可以向无人机发送数据转发请求。控制器响应于该数据转发请求,会建立机载设备与该控制器之间的数据传输通道,以通过该数据传输通道接收机载设备发送的目标数据。
进一步的,控制器与地面控制装置之间也建立有通信链路。可选的,在控制器将目标数据转发给地面控制装置之前,地面控制装置向控制器发送数据转发请求,控制器响应于该数据转发请求建立地面控制装置与控制之间的通信链路。
本实施例中控制器与机载设备之间建立数据传输通道的过程可以参见前面实施例中控制器与发送端建立数据传输通道的过程,而控制器与地面控制装置之间的数据链路的建立过程也可以参见前面实施例中关于建立控制器与接收端之间通信链路的相关介绍,在此不再赘述。
可选的,在发送端为机载设备的情况下,作为接收端的地面控制装置可以有多种,可选的,该地面接收装置可以为移动终端。
为了便于理解,下面以发送端为机载设备,接收端为移动终端为例,对本申请实施例的数据传输方法进行介绍。参见图2,其示出了本申请一种数据传输方法又一个实施例的流程示意图,本实施例的方法可以包括:
201,无人机的控制器接收机载设备发出的数据转发请求。
该机载设备通过所述无人机的通用接口与该无人机相连,通用接口用于连接不同类型的机载设备。
202,响应于机载设备的数据转发请求,建立控制器与机载设备之间的数据传输通道。
203,接收移动终端发送的数据转发请求。
移动终端可以直接向控制器发送数据转发请求。
可选的,移动终端可以通过无线图传模块与控制器建立连接,其中,移动终端可以通过USB总线与所述无线图传模块相连。则,控制器可以接收移动终端通过无线图传模块发送的数据转发请求,并响应于该数据转发请求,通过无线图传模块建立控制器与移动终端之间的通信链路。
204,响应于移动终端的数据转发请求,建立控制器与该移动终端之间的通信链路。
205,接收该机载设备通过数据传输通道发送的目标数据。
可选的,该目标数据可以为机载设备的状态数据。
进一步的,在该目标数据可以携带接收端标识,以根据该接收端标识确定出需要接收该目标数据的移动终端。
206,通过控制器与移动终端之间的通信链路将目标数据转发给该移动终端。
可选的,地面控制装置在接收到该目标数据之后,可以
可以理解的是,本申请实施例中步骤201和202,与步骤203和204的顺序并不限于图2所示,在实际应用中也可以先指定步骤203和204,在执行步骤201和202;也可以是在执行步骤201和202的同时,执行该步骤203和204。
可以理解的是,在发送端为机载设备的情况下,在控制器建立了机载设备与控制器的数据传输通道,以及建立了地面控制装置与机载设备的通讯链路之后,控制除了可以接收机载设备作为发送端发送的目标数据之外,控制器也可以接收地面控制装置作为发送端发送的目标数据,并将地面控制装置发送的目标数据转发给机载设备,从而通过控制器实现机载设备与地面控制装置的数据交互。
为了便于理解,对地面控制装置作为发送端,而机载设备作为接收端的情况进行介绍。
地面控制装置向控制器发送的目标数据也可以有多种可能性。可选的,地面控制装置可以向控制器发送控制数据,该控制数据用于对无人机的机载设备的运行状态进行控制。控制器将该控制数据转发给机载设备,以实现通过该控制数据控制机载设备的运行。例如,该控制数据可以为机载设备的运行配置数据,以对机载设备的程序进行配置。
可选的,与前面发送端为机载设备的数据传输过程相似,在控制器接收地面控制装置发送的控制数据之前,该地面控制装置可以向控制器发送数据转发请求,控制器响应于接收到的数据转发请求,建立控制器与地面控制装置之间的通信链路,从而在地面控制装置可以通过该通信链路向控制器发送控制数据等目标数据。
其中,控制器接收数据转发请求以及建立该通信链路的过程可以参见前面实施例的相关介绍,在此不再赘述。
可选的,与前面实施例相似,在地面控制装置作为发送端的情况中,该地面控制装置可以为移动终端。
为了便于理解,以地面控制装置为移动终端,且移动终端向控制器发送的 目标数据为以上所提的控制数据为例进行介绍。参加图3,其示出了本申请实施例一种数据传输方法另一个实施例的流程示意图,本实施例的方法可以包括:
301,接收移动终端发送的数据转发请求。
移动终端可以直接向控制器发送数据转发请求。
可选的,移动终端可以通过无线图传模块与控制器建立连接,其中,移动终端可以通过USB总线与所述无线图传模块相连。则,控制器可以接收移动终端通过无线图传模块发送的数据转发请求,并响应于该数据转发请求,通过无线图传模块建立控制器与移动终端之间的通信链路。

304,响应于机载设备的数据转发请求,建立控制器与机载设备之间的数据传输通道。
其中,303和304为可选的。
305,接收该移动终端通过该通信链路发送的控制数据。
进一步的,在该控制数据可以携带接收端标识,以根据该接收端标识确定出需要接收该控制数据的机载设备。当然,当控制数据为其他类型的目标数据时,目标数据同样可以携带接收端标识,以基于该接收端标识,确定接收该目标数据的机载设备。
306,通过控制器与机载设备之间的数据传输通道将目标数据转发给该机载设备,以便机载设备基于控制数据控制该机载设备的运行。
当然,在本实施例中,在移动终端向控制器发送控制数据的同时,机载设备也可以通过数据传输通道向控制器发送状态数据等目标数据,以便控制器将机载设备的目标数据转发给移动终端,从而实现机载设备与移动终端之间的数据互传。
可以理解的是,在发送端为移动终端等地面控制装置的场景中,为了便于控制器识别当前接收到的数据为需要转发的数据,则地面控制装置向控制器发送的目标数据同样可以为指定协议格式的数据。
