Description

一种遥控设备与主机的连接方法
本申请要求于2019年7月31日提交中国专利局、申请号为201910702605.8、发明名称为“一种遥控设备与主机的连接方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明属于遥控技术领域，具体涉及一种遥控设备与主机的连接方法。
背景技术
现有市面上，利用蓝牙、红外等遥控信号的遥控设备来控制主机已是成熟技术，例如利用蓝牙遥控信号的遥控设备(例如蓝牙遥控器、支持蓝牙功能的手机、手环等电子产品)的使用都是基于蓝牙低功耗(Bluetooth Low Energy，或称Bluetooth、LE、BLE)技术,通过BLE中HID协议来进行按键的传输，实现按键时对空调、音箱、摄像头、机顶盒、电视机等主机控制。举例说明，在蓝牙遥控器的使用过程中，首先将蓝牙遥控设备与某一主机完成配对，一旦配对之后，蓝牙遥控设备使用白名单广播机制，其他主机无法搜索并连接到该蓝牙遥控设备，即使搜索到该主机也无法实现连接，即实现蓝牙遥控设备与主机的一对一绑定。在用户想要利用此蓝牙遥控设备控制其他主机时，一般遥控器会提供一个组合按键或者有的蓝牙遥控设备根本不支持切换主机的功能，并且在支持的情况下，一旦组合按键被按下，最初连接的主机不可能再被控制，导致蓝牙遥控设备控制的主机单一，降低了蓝牙遥控设备的通用性。
本背景技术所公开的上述信息仅仅用于增加对本申请背景技术的理解，因此，其可能包括不构成本领域普通技术人员已知的现有技术。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对本发明实施例或现有技术描述中所需要使用的附图作一简要介绍，显而易见地，下面描述的附图是本发明的一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他附图。
图1为本发明的遥控设备与主机的连接方法一个实施例的流程图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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。
现有遥控设备(例如遥控器、具有功能的手机或手环等智能设备)对能够接收遥控信号的单一主机(例如冰箱、空调器、电视机、机顶盒、音箱、摄像头等智能家居产品)发送白名单广播，在遥控设备与该主机断开时，其他主机也搜索不到该遥控设备，并且遥控设备也不能切换控制其他主机，使得单个遥控设备与单个主机一一绑定。随着家用智能家居产品数量的增加，如果一个主机需要配备一个遥控设备，不仅造成资源上的浪费，而且用户会 混淆各遥控设备，数量多也容易导致混乱或丢失。
为此，本发明提供一种遥控设备与主机的连接方法，将单个遥控设备与多个主机切换连接，实现遥控设备的通用性，且避免用户使用多个遥控设备分别控制各个主机，提升用户体验。在本实施例遥控设备与主机的连接方法中主机的数量为至少两个且能够与遥控设备建立通讯连接，本实施例遥控设备与主机的连接方法包括如下步骤：遥控设备连接至第一主机；遥控设备接收将第一主机切换至第二主机的第一控制指令，如果确认切换，遥控设备接收拟连接至第二主机的第二控制指令，遥控设备根据接收的第二控制指令解析得到第二控制指令对应的第二主机，并得到第二主机对应的设备标识，遥控设备发送包含第二主机对应的设备标识的定向广播，在预定时间段内遥控设备与第二主机建立连接时，确认第一主机成功切换至所述第二主机。需要说明的是，在本发明的描述中，术语“第一”、“第二”仅用于描述目的，“第一主机”意指多个主机中的一个主机，“第二主机”意指多个主机中的另一个主机，且“第一”和“第二”不能理解为指示或暗示相对重要性。
具体地，在本实施例中，以遥控设备为蓝牙遥控器为例进行说明，当然，遥控设备也可以是通过其他通讯方式与主机建立通讯连接的设备，在此不做限定。如图1所示，其示出了本实施例中一种遥控设备与主机的连接方法的流程图。本实施例中的主机可以包括冰箱、音箱、空调器、电视机、机顶盒等能够接收遥控设备的遥控信号的智能家居产品。
S1：遥控设备连接至第一主机。
在步骤S1中，为了便于理解及说明，以遥控设备为蓝牙遥控器且第一主机为空调器为例进行描述。蓝牙遥控器当前正与空调器蓝牙连接，在用户需要用蓝牙遥控器控制电视机时，需要通过蓝牙遥控器从空调器切换至电视机，在切换之前，与蓝牙遥控器连接的空调器的信息位于蓝牙遥控器的白名单中，蓝牙遥控器通过白名单广播与空调器蓝牙连接。具体白名单中存有空调器的设备标识，具体可以为MAC(Media Access Control或者Medium Access Control，译为媒体访问控制或称为物理地址、硬件地址)地址，其用来定义网络设备的位置。可以将拟连接的所有主机的设备标识(本实施例中具体为 对应主机的MAC地址)预存在存储器中，该存储器可以位于蓝牙遥控器中，也可以设置在如路由器等的其他装置中，蓝牙遥控器可以根据拟连接的主机从存储器中读取对应的设备标识。
S2：遥控设备接收将第一主机切换至第二主机的第一控制指令。
在步骤S2中，为了便于理解及说明，以第二主机为电视机为例进行描述。
蓝牙遥控器接收第一控制指令以开启主机切换模式，本实施例第一控制指令可以为单个按键、组合按键、语音指令、手势指令、指纹指令、单击单个按键、双击单个按键等，在此不做限制，在蓝牙遥控器检测到第一控制指令时，进入步骤S201。
S201:向用户询问是否启动主机切换模式，以防止用户的误触发操作，用户输入第三控制指令确认启动主机切换模式或不启动主机切换模式，第三控制指令为单个按键、组合按键、语音指令、手势指令、指纹指令、单击单个按键、双击单个按键等。在本实施例中，第三控制指令优选为单击设定的单个按键。
S3：如果确认启动主机切换模式，则进入步骤S301。在步骤S3中，为了便于理解及说明，以遥控设备为蓝牙遥控器、第一主机为空调器、且第二主机为电视机为例进行说明。
S301：蓝牙遥控设备接收拟连接至第二主机的第二控制指令，处理器根据第二控制指令解析得到第二控制指令对应的第二主机，并从存储器中读取第二主机对应的设备标识，其中处理器可以设置在遥控设备中，也可以设置在如路由器等的其他装置中。在本实施例中，处理器设置在遥控设备中。在读取到第二主机对应的设备标识后，则进入步骤S302。
S302：蓝牙遥控设备发送包含第二主机对应的设备标识的定向广播。
如果用户输入第三控制指令为不需要启动主机切换模式，则进入步骤S303。
S303：蓝牙遥控设备通过白名单广播重新连接至空调器。
具体地，询问用户是否启动主机切换模式，用户例如输入输入第三控制 指令确认不需要启动主机切换模式时，蓝牙遥控设备发送白名单广播，实现蓝牙遥控器仍与第一主机的连接并正常使用，此时白名单中可以只有当前连接的主机的设备标识，在本实施例中为空调器的MAC地址，这样可以实现在误触的情况下，快速建立与第一主机的重新连接；如果用户需要切换，则蓝牙遥控器接收第二控制指令，第二控制指令可以是单个按键、组合按键、语音指令、手势指令或指纹指令等，在本实施例中，优选为语音指令，在蓝牙遥控器检测到第二控制指令时，根据第二控制指令解析得到第二控制指令对应的第二主机，并从存储器中读取第二主机对应的设备标识，蓝牙遥控器首先断开与空调器的连接，然后发送包含电视机对应的设备表标识的定向广播，在定向广播的情况下，除了电视机其他主机无法搜索到该蓝牙遥控器。
定向广播符合BLE协议，主要用于实现移动智能终端与周边配件之间的持续连接，是功耗极低的短距离无线通信技术，并且有效传输距离被提升到了100米以上。在蓝牙遥控器与第二主机的连接过程中，定向广播的广播频率大于白名单广播的广播频率，也就是说在单位时间内定向广播发送的次数多于白名单广播发送的次数，因此，对拟连接的第二主机来说，接收定向广播的效率要高于接收白名单广播的效率。因此，在蓝牙遥控器切换至第二主机时，通过发送包含有MAC地址的定向广播，能够实现蓝牙遥控器与第二主机之间快速准确的连接，提升连接效率。
S4：在预设时间段内遥控设备与第二主机建立连接时，确认第一主机切换至第二主机。在本实施例中，遥控设备以蓝牙遥控器且第二主机以电视机为例进行说明。
在本实施例中，当蓝牙遥控设备与电视机连接成功时，白名单中的设备标识更新为电视机的设备标识信息，即更新为电视机的MAC地址。
在蓝牙遥控器与电视机连接不成功时，进入步骤S401。
S401：向用户询问是否需要继续与电视机进行连接，用户输入第四控制指令确认继续与电视机建立连接或不继续与电视机建立连接，第四控制指令可以为单个按键、组合按键、语音指令，手势指令，指纹指令等，在本实施例中，第四控制指令优选为单击预设的单个按键。如果继续与电视机建立连接，则进入步骤S302，蓝牙遥控器重新发送包含电视机对应的MAC地址的定向广播，以与电视机进行再次连接。如果不重新连接，则进入步骤S303，蓝 牙遥控器通过白名单广播重新连接至空调器。
具体地，可以设定蓝牙遥控器与电视机的连接时间，如果在预设时间段(例如30秒)内连接失败，会询问用户是否需要继续建立连接，如果继续建立连接，蓝牙遥控器重新发送包含电视机对应的MAC地址的定向广播，以与电视机进行继续连接，如果不继续连接，蓝牙遥控器发送白名单广播，重新与空调器进行连接。
根据如上所述，当用户电视机切换至第三主机，例如音箱时，蓝牙遥控器与电视机断开且与音箱连接的过程及原理类似于蓝牙遥控器与空调器的断开且与电视机的连接，在此不做赘述。
如果蓝牙遥控器和多个主机进行过连接，并在白名单中保存了多个主机的设备信息，例如MAC地址，蓝牙遥控器在发送广播时，任意一个曾经连接过的主机都可以对此设备发起连接并连接成功。但是，遥控器的实际应用中一般只会控制一个主机，只需要保存一个主机的MAC地址，蓝牙遥控器在广播时其他设备也不应对此遥控器发起连接，因此，一旦蓝牙遥控器与电视机连接成功后，蓝牙遥控器将清除之前白名单中的空调器的MAC地址而将电视机的MAC地址添加至白名单中，以便在切换主机时，在遥控器端仍通过发送定向广播，实现蓝牙遥控器与主机的快速连接。
当然，也可以在蓝牙遥控器与电视机连接成功后，蓝牙遥控器不清除之前白名单中的空调器的MAC地址而将电视机的MAC地址也添加至白名单中，此时空调器和电视机的MAC地址均在白名单中，因此在切换返回空调器时，通过空调器的MAC地址发送白名单广播进行连接。
本实施例的蓝牙遥控设备与主机的连接方法，在蓝牙遥控设备内预存有各主机的MAC地址，蓝牙遥控设备通过主机对应的MAC地址向主机发送定向广播，定向广播的发送频率高，缩短蓝牙遥控器与主机建立连接时需要的时间，提升两者连接效率；由于蓝牙遥控设备内预存有各主机的MAC地址，通过发送定向广播，将各主机通过蓝牙遥控设备联系在一起，通过蓝牙遥控设备可灵活切换各主机，提高蓝牙遥控设备的使用范围，提升其通用性，避免多个主机使用多个蓝牙遥控设备所带来的麻烦，提升用户使用体验。
在此说明一下，本专利技术可以应用于蓝牙领域，也可以应用于其他通讯连接的领域。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
