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作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。
下面结合附图,对本发明的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
在控制系统中,通常当遥控信号所在的无线环境受到干扰或者远程受控制设备超出某个距离时,会出现遥控信号断链的情况,也就是常说的“丢控”现象。例如,航拍机飞行到一定的高度时,可能会出现丢控现象,在这种情况下航拍机的安全性和可靠性将显著降低。为了解决上述问题,本发明实施例提出一种对电子设备的遥控方法,该方法可以应用于遥控设备,通过自适应的改变遥控信号的发送频率、信号精度以及丢弃部分低优先级遥控通道的方法来保持对被控电子设备的遥控控制,从而应对各种可能出现的无线环境和远距离控制场景,确保被控电子设备的可靠性和操控性。
本发明实施例提供一种遥控系统,如图1所示,该遥控系统包括遥控设备和电子设备。其中,遥控设备是具有遥控功能的一种设备(如遥控器、手机、平板电脑、地面控制站等),用于通过向电子设备发送遥控信号以控制电子设备的移动以及执行相关的功能操作。例如,遥控设备可以控制电子设备的移动方向(如向左移动或向右移动),还可以控制电子设备的移动速度(如以20公里/小时移动)。又例如,当电子设备具备拍摄功能时,遥控设备可以控制电子设备进行图像拍摄。
电子设备是被所述遥控设备控制的设备,用于根据遥控设备的遥控信号进行移动或执行相关的功能操作。例如,电子设备根据接收到的遥控设备的遥控信号确定向前移动或向后移动。又例如,当遥控设备的遥控信号包括执行定点悬停时,电子设备根据接收到的遥控设备的遥控信号在指定的定点停止移动。其中,电子设备可以是可移动平台(如无人机、无人车和移动机器人等),也可以是中继设备(如作为中继的无人车,无人机等)。可以理解的是,遥控设备和被遥控的电子设备可以是一一对应的关系,也可以是一个遥控设备对应多 个被遥控的电子设备,通过在遥控设备上切换控制以实现对多个电子设备的遥控控制。图1所示的遥控系统仅为一种示例,该遥控系统还可以包括多个遥控设备和多个电子设备,本实施例不作限制。
在本发明实施例提供的遥控系统中,遥控设备和电子设备之间采用数字遥控链路。通常来讲,数字遥控链路包括以下几个部分:遥杆,采集,数模/模数转换,编码,发送,接收,解码和输出。数字遥控链路中传输的遥控信号的遥控信号负载通常包括遥控通道数、杆量位宽或杆量频率中的一个或多个。其中,遥控通道数对应了遥控设备可以实现的多种遥控功能,包括不同用途的遥杆、拨杆、开关和按键等,遥控通道数越多,遥控设备的功能越丰富。杆量位宽表示遥控设备传输的控制杆量对应的比特数,当杆量位宽越高(比特数越多)时,遥控设备可以实现更微小精确的操作,当杆量位宽越低(比特数越少)时,遥控设备的操作越粗糙,可能出现遥控不到位的情况。杆量频率表示遥控杆量的发送频率,当杆量频率越高时,遥控设备的控制手感越灵敏,当杆量频率越低时,遥控设备的控制手感越迟钝。通常来讲,遥控设备的杆量频率在50Hz-200Hz之间,遥控设备具备较好的操控性。
本发明实施例提供一种遥控方法,请参见图2,该方法可以应用于图1所示的遥控系统中,具体包括以下步骤:
S201,电子设备根据来自于所述电子设备的遥控设备的历史遥控信号,确定所述遥控设备与所述电子设备之间的通信链路的信道容量估计值。
所述历史遥控信号为电子设备根据接收到的遥控信号的接收质量,估算出的遥控信号所在通信链路的有效容量。其中,遥控信号的接收质量可以包括但不限于遥控设备与电子设备之间的通信链路的信号强度和信噪比等。链路的信号强度是电子设备的无线适配器接收到的信号的强度,以dBm计量。信噪比是遥控设备与电子设备之间的通信链路的信号与噪声的比例,以dB计量,一般来说,信噪比越大,说明混在信号里的噪声越小,信号质量越高。电子设备根据遥控信号的接收质量可以获取遥控信号的带宽以及发送功率,根据遥控信号的带宽以及发送功率可以确定遥控信号的编码率以及调制方式,进而得到遥控设备与电子设备之间的通信链路的信道容量估计值。其中,所述信道容量估 计值表示遥控设备和电子设备之间的通信链路的最大容量,以比特数计量。
S202,电子设备向遥控设备发送所述遥控设备与所述电子设备之间的通信链路的信道容量估计值。
电子设备根据历史遥控信号确定遥控设备和电子设备之间的通信链路的信道容量估计值后,可以将所述信道容量估计值通过下行无线信道发送给遥控设备,以使遥控设备获取遥控设备和电子设备之间的通信链路的信道容量估计值。
S203,遥控设备根据所述信道容量估计值对所述遥控设备当前生成的遥控信号的遥控信号负载进行调整,得到调整后的遥控信号负载。
遥控设备当前生成的遥控信号的遥控信号负载包括遥控通道数、杆量位宽或杆量频率中的一个或多个。在本实施例中,遥控设备可以根据信道容量估计值自适应地调整当前的遥控信号负载,以确保遥控设备的可靠性和操控性。调整方式可以包括以下两种:
若所述信道容量估计值小于所述遥控设备当前的遥控信号负载,降低所述遥控设备当前的遥控信号负载;或者,
若所述信道容量估计值大于所述遥控设备当前的遥控信号负载,增加所述遥控设备当前的遥控信号负载。
其中,当信道容量估计值小于遥控设备当前的遥控信号负载时,若不降低当前的遥控信号负载,则遥控设备对电子设备的控制可能会出现失控的情况。降低遥控设备当前的遥控信号负载可以包括降低遥控信号的遥控通道数,降低遥控信号的杆量位宽,降低遥控信号的杆量频率中的一种或多种。例如,对于要求精确控制的穿越机,遥控信号的杆量位宽和杆量频率需要优先保证,可以先减少不必要的遥控通道;当信道进一步受限时,可以同步地减少杆量位宽和杆量频率。
当信道容量估计值大于遥控设备当前的遥控信号负载时,遥控设备可以通过增加遥控设备当前的遥控信号负载以使遥控设备能够达到当前信道条件下的更优的控制性能。增加遥控设备当前的遥控信号负载可以包括增加遥控信号的遥控通道数,增加遥控信号的杆量位宽,增加遥控信号的杆量频率中的一种或多种。例如,对于操作频率较小的固定翼无人机,可以优先增加遥控通道数 以使遥控设备具备更丰富的遥控功能。
S204,遥控设备根据所述调整后的遥控信号负载调整所述遥控信号,将调整后的遥控信号发送给所述电子设备。
遥控设备可以根据调整后的遥控信号负载调整遥控信号。例如,若调整前的遥控信号负载中的杆量频率为每一秒发送一次遥控信号,调整后的遥控信号负载中的杆量频率为每两秒发送一次遥控信号,则遥控设备将调整遥控信号,调整为每两秒发送一次遥控信号。遥控设备对遥控信号进行调整之后,可以将调整后的遥控信号发送给电子设备以调整对电子设备的遥控控制。相对应地,电子设备将接收调整后的遥控信号。
本发明实施例提供一种遥控方法,所述遥控方法可以应用于遥控系统,所述方法包括电子设备获取所述遥控设备与所述电子设备之间的通信链路的信道容量估计值,并将所述信道容量估计值发送给遥控设备;遥控设备根据所述信道容量估计值对所述遥控设备当前生成的遥控信号的遥控信号负载进行调整,得到调整后的遥控信号负载;根据所述调整后的遥控信号负载调整所述遥控信号,将调整后的遥控信号发送给所述电子设备。采用该方法,遥控设备通过评估与电子设备之间的通信链路的质量,自适应地调整当前的遥控信号负载,可以在确保遥控可靠性的前提下获取当前通信链路质量下更优的控制性能。
结合图2所示的实施例中的遥控方法的描述,本发明实施例提供了遥控设备根据信道容量估计值对遥控设备当前生成的遥控信号进行调整的具体方法。其中,在信道容量估计值小于遥控设备当前的遥控信号负载的情况下,遥控设备可以降低当前的遥控信号负载,请参见图3,具体可以包括以下步骤:
遥控设备分别获取遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级;
若信道容量估计值小于遥控设备当前的遥控信号负载,遥控设备根据遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级,降低第一优先级的遥控信号负载;
若信道容量估计值小于降低后的遥控信号负载,降低第二优先级的遥控信号负载。
具体来说,遥控信号负载可以包括遥控通道数、杆量位宽或杆量频率中的一个或多个,其中,遥控通道数、杆量位宽和杆量频率可以分别对应相同或不同的优先级。在一种可行的实现方式中,遥控通道数、杆量位宽和杆量频率的优先级可以与电子设备的运行环境相对应,即表示不同的电子设备的运行环境分别对应不同的遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级,如表1所示。
表1:遥控信号负载的优先级与电子设备的运行环境对应关系表
Figure PCTCN2019103424-appb-000001
例如,当电子设备处于近场无干扰环境中时,遥控设备可以采用高频率控制,则杆量频率对应地为第三优先级,杆量位宽为第二优先级,遥控通道数为第一优先级。
在另一种可行的实现方式中,遥控通道数、杆量位宽和杆量频率的优先级可以与电子设备的设备类型相对应,即表示不同的电子设备的设备类型分别对应不同的遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级,如表2所示。
表2:遥控信号负载的优先级与电子设备的设备类型对应关系表
Figure PCTCN2019103424-appb-000002
例如,当电子设备的设备类型为穿越机时,杆量位宽和杆量频率需要优先保证,则杆量位宽和杆量频率为第二优先级,遥控通道数为第一优先级。其中, 上述表1和表2中的第三优先级为最高的优先级,第二优先级为较高的优先级,第一优先级为最低的优先级。
当信道容量估计值小于遥控设备当前的遥控信号负载时,为了确保遥控信号的可靠性同时降低对遥控设备的操控性的影响,遥控设备可以降低优先级最低的遥控信号负载。例如,当遥控通道数为第一优先级,杆量位宽和杆量频率为第二优先级时,若信道容量估计值小于遥控设备当前的遥控信号负载,则遥控设备将减少遥控通道数,直至信道容量的估计值大于或等于遥控设备当前的遥控信号负载或者遥控通道数减少到预设的下限阈值。
若降低第一优先级的遥控信号负载后,遥控设备的遥控信号负载仍然大于信道容量估计值,则需要进一步降低遥控设备的遥控信号负载。具体的,可以按照优先级顺序降低第二优先级的遥控信号负载。例如,当遥控通道数为第一优先级,杆量位宽和杆量频率为第二优先级时,若信道容量估计值小于遥控设备当前的遥控信号负载,则遥控设备将首先减少遥控通道数。当遥控通道数减少到预设的阈值时,遥控设备将比较降低后的遥控信号负载是否小于或等于信道容量估计值。若降低后的遥控信号负载仍然大于信道容量估计值,则继续降低杆量位宽和杆量频率,直至信道容量估计值大于或等于遥控设备降低后的遥控信号负载。
在一种实施例中,在信道容量估计值大于遥控设备当前的遥控信号负载的情况下,遥控设备可以增加当前的遥控信号负载,请参见图4,具体可以包括以下步骤:
遥控设备分别获取遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级;
若信道容量估计值大于遥控设备当前的遥控信号负载,遥控设备根据遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级,增加第三优先级的遥控信号负载;
若信道容量估计值大于增加后的遥控信号负载,增加第二优先级的遥控信号负载。
具体来说,遥控设备分别获取遥控通道数的优先级,杆量位宽的优先级和杆量频率的优先级的步骤可以参考图3所示的实施例中遥控设备分别获取遥 控通道数的优先级,杆量位宽的优先级和杆量频率的优先级的步骤,在此不再赘述。
当信道容量估计值大于遥控设备当前的遥控信号负载时,遥控设备可以增加遥控信号负载以达到当前信道条件下的更优的控制性能。例如,当遥控通道数为第一优先级,杆量位宽为第二优先级,杆量频率为第三优先级时,若信道容量估计值大于遥控设备当前的遥控信号负载,则遥控设备将增加杆量频率,直至信道容量的估计值等于遥控设备当前的遥控信号负载或者杆量频率增加到预设的上限阈值。
若增加第三优先级的遥控信号负载后,信道容量估计值仍然大于遥控设备的遥控信号负载,则可以进一步增加遥控设备的遥控信号负载。具体的,可以按照优先级顺序增加第二优先级的遥控信号负载。例如,当遥控通道数为第三优先级,杆量位宽为第二优先级,杆量频率为第一优先级时,若信道容量估计值大于遥控设备当前的遥控信号负载,则遥控设备将首先增加遥控通道数。当遥控通道数增加到预设的上限阈值时,遥控设备将比较增加后的遥控信号负载是否等于信道容量估计值。若降低后的遥控信号负载仍然小于信道容量估计值,则继续增加杆量位宽,直至信道容量估计值等于遥控设备增加后的遥控信号负载。
本发明实施例提供了遥控设备根据信道容量估计值对遥控设备当前生成的遥控信号进行调整的具体方法,包括根据遥控设备的遥控信号负载的优先级顺序对多个遥控信号负载进行调整。采用该方法,遥控设备通过自适应地调整当前的遥控信号负载,可以在确保遥控可靠性的前提下获取当前通信链路质量下更优的控制性能。
结合上述遥控方法和遥控系统的实施例中的描述,本发明实施例提供一种遥控方法在如图1所示的遥控系统中的应用场景,如图5a和图5b所示。在图5a所示的应用场景中,以遥控设备为遥控器,电子设备为固定翼无人机为例进行详细介绍。具体可以包括以下步骤:遥控器与无人机之间通过数字遥控链路进行通信,无人机可以评估上一时刻的遥控信号的接收质量,估算出信道容量估计值,并将所述信道容量估计值发送给遥控器。遥控器接收到信道容量估 计值后,若需要对当前的遥控信道负载进行调整,则可以通过遥控器的显示界面将信道容量估计值和当前的遥控信号负载提示给用户。用户可以根据无人机当前的运行环境和/或无人机的设备类型对当前的遥控信号负载进行调整,例如,当需要降低当前的遥控信号负载时,固定翼无人机的杆量频率为第一优先级,则首先选择降低杆量频率。用户可以根据用户手册指示的杆量频率值,手动输入调整后的杆量频率,确认无误后,遥控器将调整杆量频率以降低固定翼无人机当前的遥控信号负载,如图5b所示。可以理解的是,上述应用场景仅为图2所示的遥控方法的一种应用场景,还可以包括其他的应用场景,本实施例不作限制。
