一种通信方法、装置、移动平台及控制终端 技术领域
本发明涉及通信技术领域,尤其涉及一种通信方法、装置、移动平台及控制终端。
背景技术
在移动平台(如无人机、无人驾驶汽车等)工作的过程中,如果与控制终端(如遥控器等)的距离超过通信距离或者信号被遮挡,则会出现移动平台和控制终端之间的信号中断,移动平台失控等情况,轻者会导致移动平台不能继续执行任务,重者会导致移动平台损毁,这就要求能够时刻保证移动平台的可控,以保证作业的顺利执行。
目前,为解决通信距离和信号遮挡问题,一方面可以借助于现有的移动通信网,例如第三代移动通信技术(the 3rd Generation mobile communication technology,3G)/第四代移动通信技术(the 4th Generation mobile communication technology,4G)网络,但由于3G/4G网络覆盖问题,尤其是空中覆盖不连续,导致使用场景受限。另一方面可以使用信号中继技术,在移动平台和控制终端能直接通信的时候,移动平台和控制终端直接通信;在移动平台被遮挡,或者通信质量不能满足要求的时候,移动平台和控制终端需要通过中继设备来完成间接通信,但由于中继设备的引入会加大图传和控制延迟,另外在直接通信和间接通信之间切换时移动平台和控制终端之间的通信会中断,并且中断的时间包括判决时间以及通信建立时间,这段时间短则几百毫秒,长则数秒,在这段时间内移动平台是不可控的。可见,上述方案都无法保证移动平台的实时可控。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。

可选的,中继设备的数量可以为多个,则此时通信链路LINKB、通信链路LINKC以及中继设备之间的通信链路作为移动平台与控制终端之间的间接通信链路。

其中,第一控制业务数据与第二控制业务数据的数据内容相同,移动平台可以通过直接通信链路和间接通信链路接收到两份数据内容相同的控制业务数据。
具体的,移动平台在同一个工作周期内接收第一控制业务数据与第二控制业务数据,以保证移动平台在同一个工作周期内既可以收到控制终端通过直接 通信链路发送的控制业务数据,又可以收到控制终端通过间接通信链路发送的控制业务数据。
需要说明的是,步骤201和步骤202在具体执行时没有先后顺序之分,当然也可以同步执行。
203、从所述第一控制业务数据和所述第二控制业务数据中选中其中一种作为目标控制业务数据,并根据所述目标控制业务数据控制所述移动平台。
具体的,移动平台可以从第一控制业务数据和第二控制业务数据中选中其中一种作为待使用的目标控制业务数据,并根据目标控制业务数据控制移动平台。对于第一控制业务数据和第二控制业务数据中没有被选中的控制业务数据,移动平台可以丢弃,不予使用。
本发明实施例中,移动平台接收控制终端通过直接通信链路发送的第一控制业务数据,并接收控制终端通过间接通信链路发送的第二控制业务数据,其中,直接通信链路为移动平台与控制终端建立的直接通信链路,间接通信链路为移动平台通过中继设备与控制终端建立的间接通信链路,从第一控制业务数据和第二控制业务数据中选中其中一种作为目标控制业务数据,并根据目标控制业务数据控制移动平台,可以实现移动平台和控制终端在直接通信和间接通信之间无缝切换,以保证移动平台的实时可控。
可选的,移动平台从第一控制业务数据和第二控制业务数据中选中其中一种作为目标控制业务数据的具体实现方式可以为:
移动平台从直接通信链路和间接通信链路中确定目标通信链路,通过目标通信链路接收的控制业务数据将会被使用,进而将第一控制业务数据和第二控制业务数据中与目标通信链路对应的控制业务数据作为待使用的目标控制业务数据,例如目标通信链路为直接通信链路,则移动平台将与直接通信链路对应的第一控制业务数据作为待使用的目标控制业务数据,并将与间接通信链路对应的第二控制业务数据丢弃,不予使用。
可选的,移动平台从直接通信链路和间接通信链路中确定目标通信链路的具体实现方式可以为:
确定直接通信链路和间接通信链路的通信质量,并根据通信质量从直接通 信链路和间接通信链路中确定目标通信链路。
可选的,确定直接通信链路的通信质量的具体实现方式可以为:
根据直接通信链路的信号接收强度(Received Signal Strength Indication,RSSI)、误块率(Block Error Ratio,BLER)和信噪比(Signal Noise Ratio,SNR)中的一个或者多个确定直接通信链路的通信质量。
同样的,可以根据间接通信链路的信号接收强度、误块率和信噪比中的一个或者多个确定间接通信链路的通信质量。
可选的,针对信号接收强度RSSI、误块率BLER和信噪比SNR分别设置有权重系数W RSSI、W BLER和W SNR,则根据接收信号的RSSI、BLER、SNR以及对应的权重系数W RSSI、W BLER、W SNR可以计算得到通信链路的通信质量RX_QUAL,RX_QUAL=RSSI*W RSSI+BLER*W BLER+SNR*W SNR
可选的,在上一个工作周期中,假设目标通信链路为第一通信链路,其中,第一通信链路为直接通信链路和间接通信链路中的一种通信链路,第二通信链路为直接通信链路和间接通信链路中不同于第一通信链路的另一种通信链路,移动平台根据通信质量从直接通信链路和间接通信链路中确定目标通信链路的具体方式可以为:
在当前工作周期中,若第二通信链路的通信质量比第一通信链路的通信质量高出预设值时,移动平台将第二通信链路确定为目标通信链路,也就是说当前工作周期将目标通信链路从上一个工作周期的第一通信链路切换到了通信质量更好的第二通信链路,实现了通信链路的无缝切换。
否则,移动平台将第一通信链路确定为目标通信链路,也就是说当前工作周期仍然保持上一个工作周期的目标通信链路不变。
可选的,第二通信链路的通信质量比第一通信链路的通信质量高出预设值是指第二通信链路的上/下行通信链路的通信质量均比第一通信链路的上/下行通信链路的通信质量高出相应的预设值,即:
第二通信链路的上行通信链路的通信质量比第一通信链路的上行通信链路的通信质量高出上行预设值,第二通信链路的下行通信链路的通信质量比第一通信链路的下行通信链路的通信质量高出下行预设值。
可选的,以图1所示的场景为例,假设中继设备的数量为一个,通信链 路LINKA作为移动平台与控制终端之间的直接通信链路,通信链路LINKB和通信链路LINKC作为通信子链路组成移动平台与控制终端之间的间接通信链路。
RX_QUAL_LINK*_UL表示通信链路LINK*的上行通信链路的通信质量,则RX_QUAL_LINKA_UL表示移动平台接收控制终端的信号时通信链路LINKA的上行通信链路的通信质量;RX_QUAL_LINKB_UL表示移动平台接收中继设备的信号时通信链路LINKB的上行通信链路的通信质量;RX_QUAL_LINKC_UL表示中继设备接收控制终端的信号时通信链路LINKC的上行通信链路的通信质量。
RX_QUAL_LINK*_DL表示通信链路LINK*的下行通信链路的通信质量,则RX_QUAL_LINKA_DL表示控制终端接收移动平台的信号时通信链路LINKA的下行通信链路的通信质量;RX_QUAL_LINKB_DL表示中继设备接收移动平台的信号时通信链路LINKB的下行通信链路的通信质量;RX_QUAL_LINKC_DL表示控制终端接收中继设备的信号时通信链路LINKC的下行通信链路的通信质量。
其中,RX_QUAL_LINKA_UL和RX_QUAL_LINKB_UL由移动平台计算得到,RX_QUAL_LINKC_UL和RX_QUAL_LINKB_DL由中继设备计算得到并发送给移动平台,RX_QUAL_LINKA_DL和RX_QUAL_LINKC_DL由控制终端计算得到并发送给移动平台。
可选的,RX_QUAL_LINKC_UL、RX_QUAL_LINKB_DL、RX_QUAL_LINKA_DL和RX_QUAL_LINKC_DL也可以由移动平台计算得到,具体实现方式可以为:中继设备可以将LINKC的上行通信链路的RSSI、BLER、SNR以及LINKB的下行通信链路的RSSI、BLER、SNR发送给移动平台,控制终端可以将LINKA的下行通信链路的RSSI、BLER、SNR以及LINKC的下行通信链路的RSSI、BLER、SNR发送给移动平台,由移动平台根据收到的RSSI、BLER、SNR分别计算出RX_QUAL_LINKC_UL、RX_QUAL_LINKB_DL、RX_QUAL_LINKA_DL和RX_QUAL_LINKC_DL。
将RX_QUAL_LINKB_UL和RX_QUAL_LINKC_UL中的最小通信质量作为间接通信链路的上行通信链路的通信质量,记为 RX_QUAL_LINKBC_UL,则间接通信链路的上行通信链路的通信质量RX_QUAL_LINKBC_UL=min(RX_QUAL_LINKB_UL,RX_QUAL_LINKC_UL)。
将RX_QUAL_LINKB_DL和RX_QUAL_LINKC_DL中的最小通信质量作为间接通信链路的下行通信链路的通信质量,记为RX_QUAL_LINKBC_DL,则间接通信链路的下行通信链路的通信质量RX_QUAL_LINKBC_DL=min(RX_QUAL_LINKB_DL,RX_QUAL_LINKC_DL)。
其中,将目标通信链路从直接通信链路切换到间接通信链路的切换条件为:间接通信链路的上/下行通信链路的通信质量均比直接通信链路的上/下行通信链路的通信质量高出相应的预设值,即:
RX_QUAL_LINKBC_UL-RX_QUAL_LINKA_UL>OffsetUl1,且RX_QUAL_LINKBC_DL-RX_QUAL_LINKA_DL>OffsetDl1。
其中,将目标通信链路从间接通信链路切换到直接通信链路的切换条件为:直接通信链路的上/下行通信链路的通信质量均比间接通信链路的上/下行通信链路的通信质量高出相应的预设值,即:
RX_QUAL_LINKA_UL-RX_QUAL_LINKBC_UL>OffsetUl2,且RX_QUAL_LINKA_DL-RX_QUAL_LINKBC_DL>OffsetDl2。
其中,OffsetDl1、OffsetDl12、OffsetUl1、OffsetUl2是各个上/下行通信链路对应的预设值,用于防止在直接通信链路和间接通信链路之间出现乒乓切换。
可选的,为了降低切换的风险,如果当前的目标通信链路的上/下行通信链路的通信质量均高于一定质量,也就是说能够满足较高的业务要求时,即使满足上述切换条件可以不进行切换。
可选的,为了进一步解决乒乓切换,可以在发生切换后的一段时间内即使满足上述切换条件的情况下,也不再进行切换。
可选的,第一通信链路的上行通信链路的通信质量是根据第一通信链路的上行通信链路的信号接收强度、误块率和信噪比中的一个或者多个确定的,第二通信链路的上行通信链路的通信质量同理可得。
可选的,第一通信链路的下行通信链路的通信质量是根据第一通信链路的下行通信链路的信号接收强度、误块率和信噪比中的一个或者多个确定的,第二通信链路的下行通信链路的通信质量同理可得。
可选的,间接通信链路可以由多个通信子链路组成,其中,当中继设备的数量为一个时,该多个通信子链路由中继设备与控制终端之间的通信链路(如图1中的LINKC)、中继设备与移动平台之间的通信链路(如图1中的LINKB)组成。
当中继设备的数量为多个时,该多个通信子链路由中继设备与控制终端之间的通信链路、中继设备与移动平台之间的通信链路、中继设备之间的通信链路组成,此时,确定间接通信链路的通信质量的具体方式可以为:
确定多个通信子链路中每一个通信子链路的通信质量,并根据该多个通信子链路的通信质量确定间接通信链路的通信质量。
可选的,可以将该多个通信子链路的通信质量中的最小通信质量确定为间接通信链路的通信质量。
可选的,确定多个通信子链路中每一个通信子链路的通信质量的具体方式可以为:
根据每一个通信子链路的信号接收强度、误块率和信噪比中的一个或者多个确定每一个通信子链路的通信质量。
可选的,间接通信链路的上行通信链路的通信质量是指每一个通信子链路的上行通信链路的通信质量中的最小通信质量,间接通信链路的下行通信链路的通信质量是指每一个通信子链路的下行通信链路的通信质量中的最小通信质量。
可选的,每一个通信子链路的上行通信链路的通信质量是根据通信子链路的上行通信链路的信号接收强度、误块率和信噪比中的一个或者多个确定的。
可选的,每一个通信子链路的下行通信链路的通信质量是根据通信子链路的下行通信链路的信号接收强度、误块率和信噪比中的一个或者多个确定的。
可选的,移动平台从直接通信链路和间接通信链路中确定目标通信链路 的具体方式也可以为:
移动平台接收控制终端发送的通信链路指示信息,其中,通信链路指示信息用于指示目标通信链路,移动平台根据通信链路指示信息即可从直接通信链路和间接通信链路中确定目标通信链路。其中,通信链路指示信息是由控制终端通过直接通信链路向移动平台发送的,或者,通信链路指示信息是由控制终端通过间接通信链路向移动平台发送的。
可选的,通信链路指示信息是由控制终端通过直接通信链路和间接通信链路向移动平台发送的,这样可以充分保证移动平台能够接收到通信链路指示信息。
可选的,移动平台发送第一状态业务数据,其中,第一状态业务数据为移动平台通过直接通信链路向控制终端发送的状态业务数据。移动平台发送第二状态业务数据,其中,第二状态业务数据为移动平台通过间接通信链路向控制终端发送的状态业务数据。移动平台发送通信链路指示信息,以使控制终端根据通信链路指示信息从直接通信链路和间接通信链路中确定目标通信链路,并将第一状态业务数据和第二状态业务数据中与目标通信链路对应的目标状态业务数据发送给显示设备。
具体的,移动平台在同一个工作周期内通过直接通信链路向控制终端发送第一状态业务数据,并通过间接通信链路向控制终端发送第二状态业务数据,第一状态业务数据与第二状态业务数据的数据内容相同,以保证控制终端在同一个工作周期内既可以收到移动平台通过直接通信链路发送的状态业务数据,又可以收到移动平台通过间接通信链路发送的状态业务数据。
进一步的,移动平台向控制终端发送通信链路指示信息,移动平台具体可以通过直接通信链路或者间接通信链路向控制终端发送通信链路指示信息,以使控制终端根据通信链路指示信息从直接通信链路和间接通信链路中确定目标通信链路,控制终端就可以将第一状态业务数据和第二状态业务数据中与目标通信链路对应的目标状态业务数据发送给显示设备,能够及时地将移动平台的状态业务数据显示出来,保证了显示的状态业务数据的连续性。
可选的,移动平台具体可以通过直接通信链路和间接通信链路向控制终端发送通信链路指示信息,这样可以充分保证控制终端能够接收到通信链路 指示信息。
可选的,移动平台、中继设备、控制终端之间的数据传输方式可以采用时分双工/频分双工中的任一种与时分多址/频分多址/码分多址中任一种的组合。中继设备可以看作是控制终端和移动平台通信模块的合体,一方面能和移动平台保持上下行通信,是控制终端的角色,另一方面能和控制终端保持上下行通信,是移动平台的角色。
举例来说,以时分双工、时分多址的数据传输方式为例,如图3a所示,假设一个最小工作周期用5个子帧来表示。其中,子帧1是移动平台发送给中继设备和控制终端;子帧2是控制终端发送给移动平台,对于中继设备来说这个子帧是空闲IDLE子帧;子帧3是控制终端发给中继设备,对于移动平台来说这个子帧是IDLE子帧;子帧4是中继设备发给移动平台,对于控制终端来说这个子帧是IDLE子帧;子帧5是中继设备发给控制终端,对于移动平台来说这个子帧是IDLE子帧,各个子帧是通过不同的时隙进行收发的,对于控制终端而言,子帧1和子帧2是和移动平台通信的子帧,子帧3和子帧5是和中继设备通信的子帧,使得在一个最小工作周期里面,移动平台和控制终端之间的通信链路、移动平台和中继设备之间的通信链路、中继设备和控制终端之间的通信链路都分别保持着一对上下行连接。
可选的,最小工作周期包括的5个子帧的先后顺序不做限定,例如,子帧1是控制终端发送给移动平台,而子帧2是移动平台发送给中继设备和控制终端,等等。
可选的,最小工作周期包括的子帧的数量不做限定,例如,最小工作周期可以包括10个子帧或者15个子帧,等等。
可选的,数据传输方式可以是频分双工、频分多址的组合,如图3b所示,各个子帧是通过不同的频段进行收发的,移动平台和控制终端之间的通信链路、移动平台和中继设备之间的通信链路使用频段1/2工作;中继设备和控制终端之间的通信链路使用频段3/4工作,对于中继设备和控制终端来说,需要同时支持频段1/2和频段3/4。
可选的,数据传输方式可以是时分双工、频分多址的组合。以图3a中的子帧2为例,控制终端和中继设备可以在相邻载波上同时给移动平台发送数 据,移动平台在接收时以更宽的带宽同时把控制终端和中继设备的数据接收下来。同理,移动平台和中继设备向控制终端发送数据时也可以在相邻载波上发送,这样可以充分利用时域和频域的灵活性,有效提高通信效率。
可选的,数据传输方式可以是时分双工、码分多址的组合。以图3a中的子帧2为例,控制终端和中继设备在相同载波但是以不同的扰码同时给移动平台发送数据,两个扰码正交,移动平台在接收时利用扰码来区分是控制终端发送的数据还是中继设备发送的数据。同理,移动平台和中继设备向控制终端发送数据时也可以用相互正交的扰码。
请参阅图4,为本发明实施例提供的另一种通信方法的流程示意图。本实施例中所描述的通信方法应用于移动平台的控制终端,所述通信方法可以包括以下步骤:
401、接收第一状态业务数据,其中,所述第一状态业务数据为所述移动平台通过直接通信链路向所述控制终端发送的状态业务数据,其中,所述直接通信链路为所述移动平台与所述控制终端建立的直接通信链路。
402、接收第二状态业务数据,其中,所述第二状态业务数据为所述移动平台通过间接通信链路向所述控制终端发送的状态业务数据,其中,所述间接通信链路为所述移动平台通过中继设备与所述控制终端建立的间接通信链路。
其中,第一状态业务数据与第二状态业务数据的数据内容相同,控制终端可以通过直接通信链路和间接通信链路接收到两份数据内容相同的状态业务数据。
具体的,控制终端在同一个工作周期内接收第一状态业务数据与第二状态业务数据,以保证控制终端在同一个工作周期内既可以收到移动平台通过直接通信链路发送的状态业务数据,又可以收到移动平台通过间接通信链路发送的状态业务数据。
需要说明的是,步骤401和步骤402在具体执行时没有先后顺序之分,当然也可以同步执行。
