背景技术
侦听机包括外壳、用以接收并处理天线信号的射频组件、及用以接收射频组件输入信息的线路板组件。射频组件与线路板组件通过线缆连接以传递信息，而该传递信息的方式需要在射频组件与线路板组件之间设置较大的空间用以容纳线缆等物件。侦听机应用于无人机领域，因此侦听机的体积小，其内部空间有限，射频组件与线路板组件之间数据传输量大，射频组件与线路板组件通过线缆连接的方式，则线缆需要占据侦听机内部极大空间用以弯曲及容纳。
同时，侦听机可处于室外环境下工作，其具有良好的密封性能。而射频组件及线路板组件设于外壳内，并工作过程中产生大量的热量。如果不能将侦听机内部的热量及时散发，会影响侦听机的正常工作乃至引起设备故障。而且侦听机需要接收的信号繁多，而侦听机的内部空间小，使得布置元器件空间小，导致侦听机的功能少。

如图1、图2及图4所示，根据一示例性实施例示出的一种侦听机。该侦听机包括外壳10、线路板组件20、第一射频组件30及第二射频组件40，侦听机与天线装置通信连接，用以接收和处理天线装置传递的信号或向外发送信息。外壳10包括第一壳体11以及与第一壳体11匹配的第二壳体12，在第二壳体12和第一壳体11之间形成有内部安装空间。可选地，线路板组件20及第一射 频组件30组装于第一壳体11内，第二射频组件40组装于第二壳体12内。
如图2和图3所示，第一射频组件30及线路板组件20组装至第一壳体11，其中，第一射频组件30与第一壳体11紧固连接，且第一射频组件30至少部分通过导热介质与第一壳体11贴合。第一射频组件30组装至第一壳体11并与之匹配，两者接触紧密，散热效率高。
线路板组件20通过紧固件直接组装至第一壳体11或通过安装螺柱等结构组装至第一射频组件30，并与第一射频组件30通过第一连接器50进行通信连接。在一实施例中，第一连接器50包括设于线路板组件20的第一连接件51、及设于第一射频组件30且与第一连接件51相匹配的第二连接件52，第一连接件51和第二连接件52插接并建立通讯。其中，第一连接器50可采用板对板连接器或者其它连接器，如柔性电路板连接器等。第一射频组件30与线路板组件20通过第一连接器50插接连接，两者的通信效果好，安装位置稳定且所需安装空间小，外壳10的内部空间使用率高。
第一射频组件30包括第一射频板31、及设于第一射频板31的至少一处理器单元。处理器单元凸出第一射频板31的表面，相邻处理器单元之间间隔设置。相应地，第一壳体11设有与处理器单元数目相匹配的第一屏蔽槽111，第一屏蔽槽111用以容纳处理器单元，使处理器单元之间相互间隔开。可选地，在第一屏蔽槽111内与处理单元的发热部位对应的位置设有与处理器单元接触的导热介质。导热介质采用导热率高的导热垫或导热硅脂等，将处理器单元产生的热量迅速传递至第一壳体11。相应地，在外壳10的外表面设有若干凸出且间隔分布的板状散热筋13，以增大外壳10的散热面，提高散热效率，散热效果好。
第一射频组件30还包括第一屏蔽罩32，该第一屏蔽罩32至少部分地覆盖第一射频板31且位于第一射频板31与线路板组件20之间，使得第一射频组件30与线路板组件20之间的信号干扰少。相应地，在第一屏蔽罩32开设有避让孔及连接孔等，用以使第一射频板31与线路板组件20之间的连接。
如图4和图5所示，第二射频组件40组装至第二壳体12，其中，第二射频组件40朝向第二壳体12的一侧面通过导热介质至少部分贴合至第二壳体12， 以使得第二射频组件40运行过程中产生的热量迅速传递至第二壳体12。
第二射频组件40至少部分与第二壳体12贴合，用以将第二射频组件40上主要发热部位散发的热量传递至第二壳体12上。第二射频组件40通过第二壳体12进行散热，可以提高侦听机内部的散热效率，避免热量在局部累积从而影响侦听机的工作与运行。第二壳体12或第一壳体11组装有密封圈73，该密封圈73用以密封第二壳体12与第一壳体11之间的贴合面，避免雨水及潮湿空气进入到安装空间，保持外壳10的密封性。
在一实施例中，第二射频组件40设于第二壳体12内，第二射频组件40包括第二射频板41与第二射频板41和/或第一射频组件30连接的至少一天线输入端口33，天线输入端口33向第二射频板41和/或第一射频组件30输入天线信号，在第二射频板41上设有至少一处理器单元。其中，天线输入端口33组装至第一壳体11。
例如，天线输入端口33设有四个，两个分布与第一壳体11的一端。其余的分布与第一壳体11的另一端等，天线输入端口33与第二射频板41和/或第一射频组件30通过导线连接。
处理器单元分布在第二射频板41的不同区域内以对应处理天线信号。为避免处理器单元之间的相互干扰，在第二壳体12上设有与处理器单元的数目相匹配的第二屏蔽槽121。当第二射频板41组装至第二壳体12时，对应的处理器单元容纳在对应的第二屏蔽槽121内，以减小处理器单元之间的相互干扰，提高信息处理的准确性及稳定性。
处理器单元在进行信号处理过程中会在局部产生高温和热量。为使处理器单元保持在合理的运行温度范围内，在第二屏蔽槽121内设有与处理器单元接触的导热介质，该导热介质处于第二屏蔽槽121内的位置与处理器单元上主要产生热量的位置相对应。导热介质同时贴合在处理器单元与第二壳体12的内壁上，将处理器单元的热量传递至第二壳体12上，并通过第二壳体12进行散热。可选地，该导热介质采用导热垫或导热硅脂。第二屏蔽槽121内的导热介质迅速将处理器单元产生的热量传递至外壳10并散发，使处理器单元工作温度稳定， 散热效果好，处理器单元的运行稳定性好。
第二射频组件40与线路板组件20通过第二连接器60进行通信连接，其中，第二连接器60至少部分凸出第二射频组件40的表面。在一实施例中，第二连接器60包括设于线路板组件20的第三连接件61、及设于第二射频组件40且与第三连接件61相匹配的第四连接件62。当第二壳体12配合安装至第一壳体11，并使第二壳体12密封贴合至第一壳体11时，第三连接件61和第四连接件62插接并建立通讯。其中，第二连接器60可采用板对板连接器或者其它连接器，如柔性电路板连接器等。
线路板组件20与第二射频组件40通过第三连接件61与第四连接件62的插接连接并导通，两者所需的安装空间小。同时第三连接件61与第四连接件62为刚性结构，两者插接连接形成的间距稳定，接触性能好。侦听机的内部空间利用率高，减小侦听机的整体体积。
为降低第二射频组件40与线路板组件20之间的相互干扰，在第二射频组件40与线路板组件20之间设有第二屏蔽罩42，该第二屏蔽罩42至少部分覆盖第二射频板41。其中，第四连接件62设于第二射频板41上并靠近第二射频板41的边缘处，第二屏蔽罩42避开第四连接件62所处区域并罩设在第二射频板41上，以达到最大的屏蔽区域。
如图2和图4所示，第一射频组件30与第二射频组件40均用以处理射频信号，为提高侦听机的处理效率及优化处理器资源，在第一射频组件30与第二射频组件40之间合理分配射频信号。可选地，第一射频组件30包括第一通信接头34，第一通信接头34与第二射频组件40通信连接。第二射频组件40包括第二通信接头43，第二通信接头43与第一射频组件30通信连接。其中，射频信号在第一射频组件30与第二射频组件40之间的传递包括以下方式；

2、第二通信接头43与第一射频组件30直接插接连接。
3、第一通信接头34与第二通信接头43相互抵接连接，以使得第一射频组件30与第二射频组件40之间相互传递射频信号。
在一实施例中，第二通信接头43设于第二射频板41，在第二通信接头43的端部设有喇叭状凹槽结构。相应地，第一通信接头34设于第一射频板31上，在第一通信接头34的端部设有球形曲面。当第二壳体12配合安装至第一壳体11，并使第二壳体12密封贴合至第一壳体11时，第二射频组件30与线路板组件20通过第二连接器60插接连接。于此同时，第二通信接头43与第一通信接头34搭接连接，使第一射频组件30与第二射频组件40通信连接，用以传递射频信号，提高射频信号的处理效率。
如图1和图3所示，该线路板组件20包括数字控制模块21和电连接至数字控制模块21的电源模块22。数字控制模块21包括数字控制板212、及设于数字控制板212与第一射频组件30或外壳10之间的散热器211。在数字控制板212上设有第一连接件51、第三连接件61及处理单元，第一连接件51与第三连接件61间隔设于数字控制板212并分别与第一射频组件30及第二射频组件40插接连接。数字控制模块21工作运行时，处理单元处为主要发热部位。将散热器211设于第一射频组件30或外壳10与处理单元之间，并在散热器211与第一射频组件30或外壳10的接触面、及散热器211与数字控制板212的接触面之间均设有导热垫或导热硅脂等导热介质，以提高导热性能及导热的稳定性。
由于侦听机需要在室外环境下工作，容易受到雷电天气的影响，线路板组件20还包括设于在外壳10内的防雷组件23，防雷组件23与电源模块22并联设置，具体地，从电源模块22的输入口引出一条线路至所述电源模块22的同时，另外引出一条电连接线路至防雷组件23，所述防雷组件23的另一端连接至所述外壳10。在外壳10外设有接地部位，该接地部位与外壳10内的防雷组件23电连接，通过防雷组件23消除雷电对侦听机的影响，提高其使用的安全性，及在恶劣环境下持续使用，应用范围广。
电源模块22为数字控制模块21、第一射频组件30及第二射频组件40供电。在外壳10上设置有电源供电接口24，也可设置电源通信接口28。电源模块22可通过普通的交流电源进行供电，此时外部电源通过所述电源供电接口24接入并连接至电源模块22。此外，电源模块22还可以通过外部电池进行供电，电池 可通过所述电源供电接口24接入并连接至电源模块22，当所述外部电池为智能电池时，还可通过电源通信接口28接入并连接至电源模块22或数字控制模块21以进行通信。侦听机通过连接市电或外部储能设备进行供电，使用灵活方便。同时，侦听机还可以在外壳10上设置与数字控制模块21连接的数据传输接口，如USB接口25、网线接口26、外置SUB-G天线接口27等，通过有线或无线网络进行数据传递。数字控制模块21可获取各个电子元器件的信号，并进行整合处理，从所述数据传输接口输出。可选地，线路板组件20还包括设于外壳10上的指示灯组件29，其中，指示灯组件29可通过不同的灯光变换，或不同的指示灯数量，发出对应的提示信息，以方便操作者观察及体验。
如图2所示，该侦听机还设有定位组件70，该定位组件70用以定位侦听机所处的方位。在外壳10的外表面凹陷形成容纳空间，该容纳空间设于第一壳体11的侧壁上。定位组件70设于容纳空间内且与线路板组件20通讯连接。
可选地，定位组件70包括GPS模组71及固定盖72，GPS模组71设于容纳空间内，固定盖72封堵在容纳空间的开口处。GPS模组71设于独立的容纳空间内，与设于第二壳体12与第一壳体11形成的安装空间内的第一射频组件30及线路板组件20相互隔开，互相干扰少，提高定位组件70的定位精度。容纳空间呈沉孔状，方便GPS模组71的安装和调节，安装方便。通过固定盖72封堵在容纳空间的开口处，在固定盖72与外壳10之间设有密封圈73，避免密封性好，性能稳定。
