一种便携天线和机顶盒系统 技术领域
本申请涉及但不限于通信领域，尤其是一种便携天线和机顶盒系统。
背景技术
随着通信领域的发展，大家对机顶盒的要求也越来越高，DVB(Digital Video Broadcasting，数字视频广播)机顶盒在这一需求下诞生了。DVB系统按照信号传播的顺序可以分成前端系统，传输系统和终端系统。其中前端系统一般位于节目生产部门(例如电视台等部门)，而终端系统即为DVB机顶盒。根据传输系统的不同，DVB机顶盒分为DVB-C、DVB-S和DVB-T。其中，DVB-C以有线电视网为传输介质、采用的是同轴电缆；DVB-S以卫星为传输介质；DVB-T用于地面广播信道。其中，DVB-S作为当今广播电视领域的主流卫星传输标准，问世已逾十年，在世界范围内得到广泛应用。
相关技术中的卫星电视接收系统，由安装在户外、屋顶、或窗边的碟形天线来完成卫星信号的采集、然后通过高频头(Low Noise Block，LNB，也叫做低噪声下变频器)将太空中传送来的高达几GHZ的C波段信号甚至十几GHZ的Ku波段的高频率卫星载波信号变成1GHZ左右的中频的载波信号，同时进行降噪、信号放大处理后，输送给机顶盒，机顶盒将接收来的卫星信号进行调解与解码，然后将音视频信号在电视机上播放。
然而，安装在户外、屋顶或窗边的碟形天线，往往具有很大的重量和体积，在用户外出时，如果想在户外通过机顶盒收看节目，相关技术中的碟形天线根本无法满足外出携带的要求。

本发明的较佳实施方式
下面结合附图对本发明的实施方式进行描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
本发明实施例的构思点可包括，将一个整体的卫星天线的天线本体拆分 为中心面板和外延面板，在信号接收状态时，多个外延面板围绕中心面板展开形成卫星信号接收面，收纳状态时，多个外延面板收纳在一起，从而实现了在收纳时减少了天线整体的体积，使天线便于携带。
第一实施例
本实施例提供了一种便携天线，请参考图1，包括：
天线本体10，天线本体10包括中心面板101和围绕中心面板101设置的多个外延面板102；在信号接收状态，多个外延面板102围绕中心面板101展开形成卫星信号接收面，接收卫星信号；在收纳状态，多个外延面板102收纳在一起。
在信号接收状态中的天线，其大致可由卫星信号接收面捕捉卫星传递过来的微弱的卫星信号。由于卫星信号很微弱，因此，卫星信号接收面可通过汇聚的方式将微弱的卫星信号汇聚起来，因此，卫星信号接收面的形状一般是旋转抛物面，因为抛物线有将信号反射汇聚到焦点的性质。大多数天线通常是抛物面形状的，也有一些多焦点天线是由球面和抛物面组合而成，卫星信号经由抛物面天线反射后集中到它的焦点处。
同样是抛物面，天线可包括正馈天线和偏馈天线。正馈天线又称抛物线天线，其焦点在天线的中心，不论深浅，其卫星信号接收面弧度皆呈抛物线。中心焦点天线特征为盘面正圆，高频头107设置于天线的中央焦点。
偏馈天线是相对于正馈天线而言，是指偏馈天线的高频头107的安装位置不在与天线中心切面垂直且过天线中心的直线上，即天线中心的法线上。因此，就没有所谓的馈源阴影的影响，在天线面积、加工精度、接收频率相同的前提下，偏馈天线的增益可大于正馈天线。但无论是正馈天线，还是偏馈天线，它们都是旋转抛物面的截面，只是截取的位置不同而已。正馈天线和偏馈天线，其高频头107的安装位置一般在旋转抛物面的焦点上，这是由旋转抛物面的特性决定的；当旋转抛物面的旋转轴指向卫星时，电波经抛物面反射后汇聚于焦点，且行程相等。
本实施例中的卫星信号接收面，则可以是通过天线本体10中的中心面 板101和围绕中心面板101的多个外延面板102形成。在信号接收状态，外延面板102围绕中心面板101展开，形成卫星信号接收面，下面对外延面板102和中心面板101的连接关系做出举例说明。
本实施例中的便携天线还可包括支撑件103和与外延面板102对应的可伸缩连接件104，请参考图2和图3，中心面板101设置在支撑件103上端，每个可伸缩连接件104分别与支撑件103和与该可伸缩连接件104对应的外延面板102连接。支撑件103的作用可包括对天线本体10进行支撑，使天线本体10可以按照所需的角度进行放置；可选地，支撑件103可以设置为可伸缩的，或者可组装的结构，可以与三脚架配合使用，使天线的安装更加稳固。
外延面板102可通过可伸缩连接件104与支撑件103相连。可伸缩连接件104，其一可以将外延面板102相对固定起来，其二，通过调节可伸缩连接件104的长度，就可以调节相连的外延面板102与中心面板101之间的距离。在信号接收状态下，外延面板102可以围绕中心面板101展开，形成卫星信号接收面，即适当调节可伸缩连接件104的长度，使外延面板102由内到外地围绕中心面板101展开；并不是每次都需要将所有的外延面板102均展开，可以根据需求部分展开或者是完全展开，即卫星信号接收面的大小可以根据需求自定。可伸缩连接件104，可以是通过节节嵌套的管状结构形成，类似于鱼竿或者雨伞的伞杆，而对其材质没有限定；也可以是通过一些具有延展性的材质来制作可伸缩连接件104，或者是一些具有延展性的结构，如金属软管，既有硬度又有延展性，可以很好的胜任可伸缩连接件104的需求。
可选地，请参考图4，本实施例中的便携天线还可以包括支撑件103，中心面板101设置在支撑件103的上端，外延面板102包括多个依次嵌套连接的子板块1021，嵌套连接为活动连接。类似地，支撑件103设置为：对天线本体10进行支撑，使天线本体10可以按照所需的角度进行放置；可选地，支撑件103可以设置为可伸缩的，或者可组装的结构，可以与三脚架配合使用，使天线的安装更加稳固。
外延面板102可包括多个依次嵌套连接的子板块1021，例如外延面板102可由多个依次嵌套连接的子板块1021组成。嵌套连接是一种活动连接，相邻的子板块1021之间可通过滑槽或者卡扣等方式进行嵌套连接；嵌套连接 的多个子板块1021，可以通过调节嵌套连接，改变相邻子板块1021之间的交叠的程度，进而改变多个子板块1021与中心面板101之间的距离，从而实现在卫星接收状态，多个外延面板102围绕中心面板101展开，形成卫星信号接收面。本实施例中的子板块1021与外延面板102含义可以是一致的，即子板块1021就是外延面板102，也可以是外延面板102由子板块1021组成。最接近中心面板101的外延面板102，可以直接与支撑件103相连，也可以通过可伸缩连接件104与支撑件103相连，还可以与中心面板101固定或者活动连接，上述的连接方式在本实施例中均可以实现。
为了达到更好的卫星信号的接收效果，在信号接收状态，外延面板102围绕中心面板101展开形成卫星信号接收面的面积可以越大；此外，卫星信号接收面越完整，卫星信号的接收的效果也会越好。因此，在信号接收状态，多个外延面板102和中心面板101可组成封闭的抛物面。为了使多个外延面板102和中心面板101能够组成封闭的抛物面，外侧的外延面板102的尺寸可以大于内侧的外延面板102的尺寸；在外延面板102围绕中心面板101展开时，相同尺寸的外延面板102可互相组成一圈抛物面，而多个这样的抛物面相叠加，则可以组成完整的抛物面。由于天线有正馈天线和偏馈天线的区别，组成的抛物面的轮廓也会有圆形和椭圆形的区别；可以注意的是，虽然完整的抛物面其轮廓可以是圆形或者椭圆形，也并不需要必须是正圆形或者标准的椭圆，抛物面的轮廓形状对接收卫星信号的影响并不会很大，只需要形成的卫星信号接收面是抛物面即可。
外延面板102一般都设置为多层的结构，可以通过同一层的外延面板102形成一圈抛物面，也可以通过相邻的两层、三层或者多层外延面板102共同形成一圈抛物面，形成的抛物面并不会严格地是一个面，只要其大致上是一个抛物面即可。
由于外延面板102中，越靠外侧的外延面板102的尺寸越大，这可能导致收纳的时候出现问题，那么，可以用柔性材质的材料制作外侧的外延面板102，或者所有外侧面板均可采用柔性材质，这里的柔性材质本身可以包括金属和非金属，而由于接受卫星信号需要是金属，那么，可以用柔性的非金属材料，在该非金属材料上覆盖金属层，从而形成外延面板102；当然，也可 以直接通过金属制作外延面板102。
本实施例中的中心面板101、外延面板102、支撑件103、连接件、子板块1021等等，各自之间的连接都可以是可拆装的，即可以将支撑件103和中心面板101之间的连接拆装，也可以将外延面板102通过连接件与支撑件103之间的连接拆装，还可以将多个依次嵌套连接的子板块1021拆装；拆卸后的多个部件可以分装，进一步地提高天线的便携度。
可选地，本实施例中的便携天线还可以包括高频头107，高频头107设置于中心面板101上方，设置为：接收卫星信号接收面接收的卫星信号并加以处理。卫星信号接收面将卫星发送的卫星信号反射给焦点，而高频头107就设置于焦点上，即可通过卫星信号接收面增大卫星信号的强度；高频头107可以设置在中心面板101上，可以注意的是，高频头107的设置位置可以设置在卫星信号接收面形成的抛物面的焦点上，根据卫星信号接收面的形状、大小的不同，焦点也可以不同，高频头107的设置位置也可以不同，相应地，高频头107的设置方式也可以有区别，即可以通过增设支架使高频头107处于抛物面的焦点位置，也可以将高频头107直接设置在中心面板101上，或者通过拆装的方式，将支架设置在卫星信号接收面的边缘，支撑起高频头107。本实施例中的高频头107可以包括C波段的高频头107，或者Ku波段的高频头107，一个天线也可以两个高频头107均设置，实现不同的波段的卫星信号的接收。
在本实施例中，高频头107的作用可以包括对卫星信号进行降频、降噪、放大等等处理，然后将处理后的卫星信号传输给机顶盒，机顶盒对该卫星信号进行调解、编解码处理后，就可以接入相应的播放器，如音频播放器或者视频播放器，播放相应的音频和视频。
可选地，高频头107的工作过程包括：高频的卫星信号经由卫星信号接收面的金属汇聚，由位于天线上的高频头107将接收来的卫星信号进行处理，可对收集来的微弱卫星信号进行低噪声高频放大，使其能满足信号使用需求，然后对其进行低噪声降频，以及低噪声中频放大，以满足信号传输需求。
本实施例中的便携天线的天线本体10的工作可以是不需要电源的，而高频头107的工作则可以是需要电源的，因此，还可包括电池110，设置为： 为高频头107供电。这里的电池110的设置位置可以设置在天线本体10上，或者可以设置成与天线本体10分离，电池110可以通过有线或者无线的方式为高频头107供电。
此外，由于在野外，很难为电池110续电，高频头107的工作得不到保证，那么，还可以包括太阳能接收单元108，设置于至少部分外延面板102的表面，设置为：将太阳能转换为电能并传输给电池110。太阳能是非常普遍的清洁能源，在白天的野外，其利用率很高，使用条件的限制也不算大，一般外出都会选择好天气，可以保证太阳能接收单元108，即太阳能电池板的正常工作，可以为电池110续电，即为高频头107供电。
太阳能接收单元108的设置位置，可以设置于任意外延面板102的表面；由于太阳能电池板的面积越大，太阳能的利用率越高，因此，太阳能接收单元108可以设置在最外侧的外延面板102的表面，尽可能地在不影响天线本体10接收卫星信号的前提下，提高太阳能的采集利用率。
便携天线往往是和机顶盒配合使用的，便携天线接收卫星信号，处理后发送给机顶盒，然后机顶盒将卫星信号进行调解、编解码处理后，将音视频信号在相应的播放设备上播放。机顶盒的使用也是需要能源的，在便携天线有电源时，便携天线还可包括供电单元105，设置为：通过无线传输将电池110的电能传输给机顶盒，从而为机顶盒供电。
无线供电技术，从原理上可以分为以下几种：
电磁耦合，简单的理解，就是把变压器的两个绕组分开，就是某种意义上的无线供电。电磁耦合方式有其缺点，没有高磁导率的磁芯作为介质，磁力线会严重发散到空气中，导致传递效率下降，特别是在两个线圈远离的时候，下降得非常厉害，所以不适合大功率、远距离的无线供电。
电磁共振，其原理类似于声波共振的原理，两种介质具有相同的共振频率，就可以用来传递能量。
光电耦合，把电能转换为光能，通过光将能量传递到目的地再转换为电能。这种无线供电技术比较直观，而且光电转换技术也相对应用广泛。但是光的传递路径具有缺陷，就是传递路径中不能有障碍物。所以这种技术也有其局限性。
对于本实施例中的机顶盒的供电，可以通过上述的无线供电方式进行无线供电。
此外，本实施例中的便携天线还可以包括信号发送单元106，设置为：通过无线传输将处理后的卫星信号传输给机顶盒。
在通过无线传输供电和无线传输发送卫星信号之后，便携天线已经实现了无线化，没有线缆可以进一步地提高便携度，对于其存放和管理也更加方便。
本实施例提供了一种便携天线，包括天线本体，天线本体包括中心面板和围绕中心面板设置的多个外延面板，在信号接收状态，多个外延面板围绕中心面板展开形成卫星信号接收面，接收卫星信号；在收纳状态，多个外延面板收纳在一起，实现了在收纳时减小了天线本体的体积，使天线便于携带。

本实施例中，便携天线还可包括支撑件103和与外延面板102对应的可伸缩连接件104，中心面板101可设置在支撑件103上端，每个可伸缩连接件104分别与支撑件103和与该可伸缩连接件104对应的外延面板102连接。支撑件103的作用可包括对天线本体10进行支撑，使天线本体10可以按照所需的角度进行放置。
外延面板102可通过可伸缩连接件104与支撑件103相连。可伸缩连接件104，其一可以将外延面板102相对固定起来，其二，通过调节可伸缩连接件104的长度，就可以调节相连的外延面板102与中心面板101之间的距离。在信号接收状态下，外延面板102需要围绕中心面板101展开，形成卫星信号接收面，即可适当调节可伸缩连接件104的长度，使外延面板102由 内到外的围绕中心面板101展开；并不是每次都需要将所有的外延面板102均展开，可以根据需求部分展开或者是完全展开，即卫星信号接收面的大小可以根据需求自定。可伸缩连接件104，可以是通过节节嵌套的管状结构形成，类似于鱼竿或者雨伞的伞杆，而对其材质没有限定；也可以是通过一些具有延展性的材质来制作可伸缩连接件104，或者是一些具有延展性的结构，如金属软管，既有硬度又有延展性，可以很好地胜任可伸缩连接件104的需求。

本实施例提供了一种机顶盒系统，包括便携天线和机顶盒，其中便携天线中的天线本体的中心面板和围绕中心面板设置的外延面板在信号接收状态时，多个外延面板围绕中心面板展开形成卫星信号接收面，接收卫星信号；在收纳状态，多个外延面板收纳在一起，实现了在收纳时减小了天线本体的体积，使天线便于携带。
本领域的普通技术人员可以理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。本申请的保护范围以权利要求所定义的范围为准。
