Description

一种无线遥控设备
本申请要求于2019年11月8日提交中国专利局、申请号为201911088830.3、申请名称为“一种无线遥控设备”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。

具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
在介绍本实施例之前，首先介绍目前市场上已有的无线遥控设备的相关结构及一些在本申请实施例中可能出现的概念，应理解的是，本发明中对已有的无线遥控设备的结构的说明以及相关的概念解释可能会因为本发明的具体情况有所限制，但并不代表本发明仅能局限于该具体情况，并且，本申请仅介绍目前市场上已有的无线遥控设备的结构与本发明的改进点相关的部分。目前市面上的无线遥控器主要分为两大部分：一种是红外遥控器，一种是蓝牙遥控器。其中，红外遥控器采用的是红外遥控的原理，即红外遥控器通过发送一定的控制信号来实现对终端设备(如：家用电器、工业设备、医疗器械装置等)的控制，这个控制信号就是一串红外脉冲编码信号，通过发送的不同编码脉冲来表示不同的功能按键信号，终端设备通过红外接收系统接收到编码脉冲，并进行相应的解码执行相应的功能，这样就实现了红外遥控对应的终端设备的目的，但由于红外线遥控不具有像无线电遥控那样穿过障碍物去控制被控对象的能力，因此使用红外遥控器时，该红外遥控器与被控对象之间不能存在明显的障碍物，且需要红外遥控器的红外发射管对着被控对象才能操作成功，影响用户体验。而蓝牙遥控器则是利用蓝牙技术建立起遥控器与需要被控制的终端设备之 间的无线连接，之后再利用建立起来的蓝牙连接实现对终端设备的控制，目前来说一个蓝牙遥控器内部仅会设置一组射频模组以及一个蓝牙协议模块，用于实现上述所述的对终端设备的控制，这种控制方式就非常单一，使用前需要先进行蓝牙配对，配对成功后才能使用，并且被控对象单一，一般一个蓝牙遥控器只能控制对应的一个终端设备。例如，市面上的华为AI荣耀遥控器、科大讯飞AI遥控器、小米AI遥控器等都是简单的蓝牙方案。
基于此，本发明实施例提供了一种无线遥控设备，就是针对上述问题提出了另一种解决的方案，本申请实施例提供的无线遥控设备内部集成了多个通信模块，通过不同通信模块内置的不同协议模块可分别与多种终端设备建立不同种类的无线连接(如，蓝牙、Wifi等)，进而实现对这些终端设备进行控制的功能，控制方式多样，具备灵活性。
应理解的是，本发明涉及到的无线遥控设备的结构仅示例出与本发明实施例相关的部分，并且以下的对于无线遥控设备的结构的说明以及相关的概念解释可能会因为本发明实施例的具体情况有所限制，但并不代表本发明仅能局限于该具体情况，在不同实施例的具体情况可能也会存在差异，具体此处不做限定。
请参阅图1，为本发明实施例提供的一种无线遥控设备100，该无线遥控设备100采用堆叠的设计方式，将无线遥控设备100的组件进行简化，该无线遥控设备100具体包括：至少两个通信模块(为便于理解，图1中仅示出两个通信模块为例进行示意，分别为第一通信模块101和第二通信模块102，实际上还可以包括三个或三个以上的通信模块，具体此处不做限定)、第一按键103、电源模块104、PCB板105，所述至少两个通信模块(即第一通信模块101和第二通信模块102)、所述第一按键103以及所述电源模块104相互连接并设置于所述PCB板105上；所述至少两个通信模块(即第一通信模块101和第二通信模块102)用于建立与多个终端设备的无线连接，每个通信模块包括一组射频模组及一组天线(图1中未示意出)，该天线可以包括但不限于：FPC天线、PCB天线、PIFA天线、金属件天线、八木天线、陶瓷天线、可伸缩鞭状天线、倒L天线、倒F天线、金属导线天线、缝隙天线、微带贴片天线、回路天线、金属导线天线、金属螺旋式天线或LDS天线中的任一种。所述射频模组与所述天线电性连接，所述射频模组内置至少一个协议模块(图1中未示意出)，该至少一个协议模块可以包括但不限于：Wifi模块、蓝牙模块、Zigbee模块、Z-wave模块、NB-IOT模块、Lora模块、Sub-GHz模块、LTE Cat1e模块、eMTC模块、GPRS模块、NFC模组、UWB模组中的一个或多个。
也就是说，当无线遥控设备中的通信模块为两个时，即第一通信模块101和第二通信模块102，则所述第一通信模块101包括第一射频模组以及第一天线(如，FPC天线、PCB天线、PIFA天线、金属件天线、八木天线、陶瓷天线、可伸缩鞭状天线、倒L天线、倒F天线、金属导线天线、缝隙天线、微带贴片天线、回路天线、金属导线天线、金属螺旋式天线或LDS天线中的任一种)，所述第一射频模组与所述第一天线电性连接，所述第一射频模组内置至少一个第一协议模块(如，Wifi模块、蓝牙模块、Zigbee模块、Z-wave模块、NB-IOT模块、Lora模块、Sub-GHz模块、LTE Cat1e模块、eMTC模块、GPRS模块、NFC模组、UWB模组中的一个或多个)，所述第一通信模块101用于根据所述至少一个第一协议模块建立与第一目标终端设备的无线连接，所述第一目标终端设备属于所述终端设备中的一 个或多个；类似地，所述第二通信模块102包括第二射频模组以及第二天线(如，FPC天线、PCB天线、PIFA天线、金属件天线、八木天线、陶瓷天线、可伸缩鞭状天线、倒L天线、倒F天线、金属导线天线、缝隙天线、微带贴片天线、回路天线、金属导线天线、金属螺旋式天线或LDS天线中的任一种)，所述第二射频模组与所述第二天线电性连接，所述第二射频模组内置至少一个第二协议模块(如，Wifi模块、蓝牙模块、Zigbee模块、Z-wave模块、NB-IOT模块、Lora模块、Sub-GHz模块、LTE Cat1e模块、eMTC模块、GPRS模块、NFC模组、UWB模组中的一个或多个)，所述第二通信模块102用于根据所述至少一个第二协议模块建立与第二目标终端设备的无线连接，所述第二目标终端设备属于所述终端设备中的一个或多个。
所述第一按键103用于对目标终端设备输入控制指令，以控制所述目标终端设备进行相应操作，所述目标终端设备为与所述至少两个通信模块中的一个已建立无线连接的终端设备；所述电源模块104用于向所述至少两个通信模块(即第一通信模块101和第二通信模块102)以及所述第一按键103提供电源。
优选的，在本申请的一些实施方式中，无线遥控设备还可以包括如图1中的红外线模块106以及第二按键，所述第二按键可以包括一个或多个按键(如图1中示意出的107、108、109均可称为第二按键)的集合；当所述第一按键103处于休眠状态时，所述红外线模块106用于建立与所述多个终端设备的无线连接；所述第二按键(如图1中的107、108、109)用于对所述目标终端设备输入控制指令，以控制所述目标终端设备进行相应操作，所述目标终端设备为与所述红外线模块中的一个已建立无线连接的终端设备；所述电源模块104还用于向所述红外线模块106以及所述第二按键(如108、109、110)提供电源。
需要说明的是，在本申请的一些实施方式中，所述无线遥控设备还包括麦克风和语音模块，所述第一按键103用于控制麦克风的开启和关闭，如当按下该第一按键103时，麦克风开启，用于拾取外界输入的语音信号；(图1中未示意出麦克风和语音模块)；所述语音模块用于将所述语音信号识别成对应的控制指令。
还需要说明的是，在本发明的一些实施例中，存在两种以下情况：A、如果第一射频模组或第二射频模组中内置不同通信协议的模块(第一射频模组与第一天线电性连接，第二射频模组与第二天线性气连接)，且这些不同通信协议的模块同时工作，这样会带来一个问题：如果第一射频模组(或第二射频模组)中内置的两种或两种以上不同类型通信协议的模块同时工作，合路成一路射频信号输出到第一天线(或第二天线)时，两种或两种以上不同类型无线通信协议信号就之间存在冲突，射频通道有信号堵塞的问题；B、第一射频模组中的协议模块和第二射频模组中的协议模块有可能同时工作(第一射频模组与第一天线电性连接，第二射频模组与第二天线电性连接)，这样会带来一个问题：第一天线和第二天线存在隔离度问题，尤其是第一射频模组中的协议模块和第二射频模组中的协议模块的工作在同一频段，天线之间的隔离度问题非常突出(例如Wifi工作2.4GHz，蓝牙工作在2.4GHz，Zigbee工作在2.4GHz等)。上述问题采用分时复用机制，来解决上述遇到两个问题：A、如果第一射频模组(或第二射频模组)中内置的两种或两种以上不同类型通信协议的模块同时工作，采用分时复用机制，合路成一组射频信号输出时，解决信号之间存在冲 突问题，不至于两种或两种以上不同类型无线通信协议的射频信号合成一路射频信号输出到第一天线(或第二天线)时，发生堵塞问题，并提高无线传输的效率。B、如果第一射频模组中的协议模块和第二射频模组中的协议模块同时工作，采用分时复用机制，第一天线工作时，第二天线不工作；第一天线不工作时，第二天线工作，这样避免了两个天线同时工作存在的隔离度问题。
基于上述问题，在本申请上述实施例中，所述至少两个通信模块(即第一通信模块101和第二通信模块102)用于建立与多个终端设备的无线连接指的就是：在该无线遥控设备100对终端设备进行控制之前，需要先对各个需要进行控制的终端设备进行配网，即让该无线遥控器100发送的控制指令与需要被控制的多个终端设备建立一一对应的关系，之后将这一一对应的关系存储在云平台或无线遥控设备100内部，用于当需要对某个被控对象(即目标终端设备)，无线遥控设备100可以根据该对应关系识别出该被控对象，进而对该被控对象进行控制。
为便于理解，下面以两个通信模块、第一按键、语音模块和麦克风为例对本申请实施例中的无线遥控设备的配网过程进行说明：
请参阅图2，无线遥控设备702内含PCB板701，在PCB板701的射频模组801内置Wifi协议模块、蓝牙协议模块，射频模组801与天线901连接；射频模组802内置Zigbee协议模块、Z-wave协议模块，射频模组801与天线901连接。麦克风334与语音模块(图2未画出)连接的，麦克风可以设置在PCB板的正面，也可设置在PCB板的背面。
无线遥控设备702在初始模式下，需要进行配网设置：WIFI协议摄像机803、蓝牙协议音箱804、Zigbee协议灯泡805、Z-wave协议插座806进行配网设置。也就是WIFI协议摄像机803在配网所对应是无线遥控设备702中射频模组801内部的WIFI协议模块、天线901；蓝牙协议音箱804在配网所对应是无线遥控设备702中射频模组801内部的蓝牙协议模块、天线901；Zigbee协议灯泡805在配网所对应是无线遥控设备702中射频模组802内部的Zigbee协议模块、天线902；Z-wave协议插座806在配网所对应是无线遥控设备702中射频模组802内部的Z-wave协议模块、天线902。平时语音模块、射频模组801、射频模组802工作在低功耗的省电状态，以延长无线遥控设备702中电池的使用时间。语音模块也可以内置在射频模组801、射频模组802中。当按下第一按键756时，语音模块立即被激活，麦克风722发出目标呼叫(如：“小智，打开摄像机803”)时，立即唤醒对应的语音模块，对应射频模组801、天线901工作，而射频模组802、天线902与WIFI协议摄像机803没有任何配网关系，射频模组802不会唤醒，射频模组802、天线902不工作。
由上述可知，因射频模组801和射频模组802分别可以内置一种或多种不同类型的无线通信协议的模块，而射频模组801只与天线901连接，射频模组802只与天线902连接，也就是天线901要与一种或多种不同类型无线通信协议的协议模块进行电性连接，天线902也要与一种或多种不同类型无线通信协议的协议模块进行电性连接，这样天线901或天线902就需要支持一种频段或多个频段。基于此，天线901或天线902就可以采用多频段螺旋天线、多频段微带天线、多频段PIFA天线等。以双频段PIFA天线为例进行说明：PIFA 天线多采用开槽的方式实现多频的工作，缝隙的形状可为矩形、U形、H型等。PIFA天线的缝隙采用弯折路径、开槽U型缝隙加载的方式实现Z-Wave频段800MHz～900MHz(例如中国香港Z-Wave频段为919.80MHz，印度Z-Wave频段为865.20MHz等)、Zigbee频段2.4GHz的双频段工作，天线的整体形状为“G”形状。开槽技术又称“曲流技术”，是通过表面开槽来改变电流路径来实现的，即切断原来的电流路径，使电流绕槽边曲折流过而路径变长，从而改变谐振频率点。该设计方法在实际加工中容易实现，性能稳定，成本低等特点。
需要说明的是，在本申请上述实施例中，还包括电源模块723、红外线模块799以及多个按键750-755，其中电源模块723用于对无线遥控设备702中的所有元器件的正常工作提供电源，所述红外线模块799用于当麦克风不接收指令时(即在无线遥控设备702上设置有麦克风按键，平时不按麦克风按键，内部的语音模块的相关功能都处于的睡眠模式，以节省功耗)，只有超低耗的红外线功能对应I/O管脚处于扫描状态，用于检测红外线功能按键(即图2中的按键750-755)状态。这样，第一按键(即麦克风按键)的语音功能与第二按键(即控制红外线功能的按键)的红外线功能不存在相互冲突的问题。
图1以及图2所对应的实施例均是说明无线遥控设备的工作原理以及如何解决射频模组分时复用的问题，下面对各元器件在PCB板上的设置方式进行说明，具体如图3所示(以通信模块为两个为例进行说明)：按键2(该案件包括上述实施例中所述的第一按键和/或第二按键)设置在PCB板1的正面，第一射频模组3以及第二射频模组6设置在所述PCB板的背面，红外模块设置在PCB板1背面开设的供红外线模块置入的让位槽(图3中未示意出)，同时在图3中，第一天线4和第二天线5均设置在PCB板1的背面。
请参阅图5所示，红外线模块308通过手工焊接或波峰焊的焊接设置在PCB板301的背面，或，红外线模块308设置在PCB板301的正面。请参阅图5所示，红外线模块308包括红外发光二极管，并在PCB板301的上部开设有供红外线模块308置入的让位槽282，让位槽282的槽形呈漏斗状，且漏斗状的开槽上部比开槽下部大，在让位槽282开槽的中线位置放置红外线模块308。PCB板301的具有相互垂直的横向和纵向。让位槽282的槽壁与PCB板281的横向方向形成一定夹角θ:0d≦θ<90度；目的是为给红外线模块308提供合理的发射角度，因为PCB板281的开槽上部及下部尺寸及开槽与PCB板308的横向方向形成的夹角θ直接影响红外二极管的发射角度。
优选的，在本申请的一些实施方式中，实际上第一天线4和第二天线5还可以均设置在PCB板1的背面；或，第一天线4设置在PCB板1的正面、第二天线5设置在PCB板1的背面；或，第一天线4设置在PCB板1的背面、第二天线5设置在PCB板1的正面，具体此处不做限定。
优选的，在本申请的一些实施方式中，第一射频模组以及第二射频模组也可以设置在PCB板的正面，具体如图4所示：第一射频模组3以及第二射频模组6就设置在PCB板1的正面，同时，还需要说明的是，第一天线4设置在PCB板1的第一净空区域11，第二天线5设置在PCB板1的第二净空区域12，所述第一净空局域11与所述第二净空区域12分别为PCB板1在横向的中线上的对称位置。
为便于理解，可参阅图5所示的无线遥控设备的俯视图：PCB板301中设置有第二按 键307(可包括上一个或多个)、第一天线302、第二天线303、红外线模块308、第一按键304、麦克风334(放在PCB板301的正面)、第一射频模组132(放在PCB板301的背面，避免影响按键的布局)、第二射频模组133(放在PCB板301的背面，避免影响按键的布局)。在PCB板301左上角设置第一净空区域306，第一天线302设置在第一净空区域306内，在PCB板301右上角设置第二净空区域305，第二天线303设置在第二净空区域305内。第一射频模组132设置在靠近第一净空区域306位置，这样缩短第一射频模组132到第一天线302之间的射频走线(图5未示出射频走线)，减小射频走线的损耗，并减小其它信号走线或电源走线对射频走线的干扰。第二射频模组133设置在靠近第二净空区域305位置，这样缩短第二射频模组133到第二天线303之间的射频走线(图5未示出射频走线)，减小射频走线的损耗，并减小其它信号走线或电源走线对射频走线的干扰。
需要说明的是，在第一净空区域306和第二净空区域305之间的区域称为控制区域309，该控制区域309用于设置按键(如第一按键与第二按键)，且该控制区域309与第一净空区域302和第二净空区域303均无交集。在净空区域309内覆地铜箔310。第一天线303(或第二天线302)与地铜箔310形成垂直脉冲电场(垂直于PCB板301的脉冲电场)，在垂直脉冲电场的方向形成脉冲磁场，在垂直脉冲磁场方向形成脉冲电场，以此类推，形成电磁波，将无线遥控设备发出的控制指令调制成电磁波发送给被控对象(例如智能灯泡、网关、智能电视、智能空调、智能冰箱等)。地铜箔310是单端天线(例如倒F天线、PIFA天线等)中的一个不可分割的组成部分，对于倒F天线、PIFA天线来说，地铜箔310的尺寸越大越好，尤其是控制区域309内的地铜箔310对第一天线302和第一天线303的性能指标影响非常大。在控制区域309内设置第二按键307、第二按键307以及红外线模块308，考虑到红外线模块308占用空间较大，会影响第二按键307的布局，从而影响外观设计，所以将红外线模块308设置在PCB板301的背面，将第二按键307设置在红外线模块308的正面(也就是PCB板301的正面)，这样不影响第二按键307的布局及外观设计。优选将第二按键307和红外线模块308设置在PCB板301左右两端居中的位置。第一按键304设置在PCB板301的正面或背面，第一按键304设置在控制区域309内。
需要说明的是，当通信模块为多个时，则与上述图5类似，该多个通信模块包括的多组天线设置在PCB板的多个净空区域，天线的数量与净空区域的数量相同，每个净空区域设置有一组天线，所述净空区域为所述PCB板四周边缘位置；所述第一按键以及所述第二按键位于控制区域，所述控制区域与所述净空区域无交集。为便于理解，以多个通信模块为三个为例进行说明，如图6所示：PCB板301上除了有第一净空区域305和第二净空区域306之外，还有第三净空区域1110，该第三净空区域1110分布在PCB板301的右下角，在第三净空区域1110内设置第三天线1111，在第三净空区域1110的左边设计第三射频模组1112。第三射频模组1112通过阻容匹配(图6中未示意出)、射频走线(图6中未示意出)与第三天线1111电性连接。
需要说明的是，为证明本发明上述实施例中无线遥控设备的设计合理性和实用性，在图4的基础上(以图4中的无线遥控设备为家用遥控器为例)，采用Ansoft HFSS(三维结构电磁场仿真软件)分别对该家用遥控器中的第一天线302和第二天线303仿真分析，以 下是整个仿真分析的过程：
第一天线302为Wifi天线，第二天线303为蓝牙天线，PCB板301尺寸为105mm×31.5mm，板厚1.2mm，Wifi天线302和蓝牙天线303均采用倒F蛇形天线(属于PCB板载天线)，第一净空区域306为15.0mm×5.54mm，第二净空区域305为16.0mm×6.77mm。
图7给出了Wifi天线的VSWR(Voltage Standing Wave Ratio，电压驻波比)仿真图示，从图7可以得出VSWR<2，满足蓝牙天线设计要求。图8给出Wifi天线的S11(回波损耗)仿真图示，从图8可以得出S11<10dB，满足家用遥控器Wifi天线的设计要求。
图9给出了蓝牙天线的VSWR仿真图示，从图9可以得出VSWR<2，满足蓝牙天线设计要求。图10给出蓝牙天线的S11仿真图示，从图10可以得出S11<10dB，满足家用遥控器蓝牙天线设计要求。
此外，以下是针对该家用遥控器中的第一天线302和第二天线303的测试：
采用5号电池，PCB板301尺寸为105mm×31.5mm，板厚1.2mm，第一天线302和第二天线303均采用倒F蛇形天线(属于PCB板载天线)，第一天线302为Wifi天线，第二天线303为蓝牙天线，第一净空区域306为15.0mm×5.54mm，第二净空区域305为16.0mm×6.77mm；实验环境包括OTA暗室，网络分析仪。极化方式为水平极化(实际家用遥控器使用时是水平平行于地面，所以天线属于水平极化)。
表1给出了家用遥控器中的Wifi天线302在不带塑胶外壳情况下的S11测试数据：第一天线302在2412MHz频段下S11值为-10.329dB，第一天线302在2442MHz频段下S11值为-10.387dB，第一天线302在2484MHz频段下S11值为-11.003dB，第一天线302在2412MHz、2442MHz、2484MHz三个频段的S11值均小于-10dB，满足第一天线302的S11参数的要求。
