如图1所示，本发明实施例一提供一种拼接显示系统，该拼接显示系统包括显示屏阵列100，显示屏阵列100包括若干拼接在一起的LED显示单元110，每一LED显示单元110包括若干无线传输模块111，两两相邻的LED显示单元110之间通过一组相邻配对的无线传输模块111进行信号双向传输，以在显示屏阵列100中形成网格型信号传输网络。
在本实施例中，无线传输模块111具体包括发送单元和接收单元，发送单元和接收单元可以短距离点对点无线传输信号及数据，短距离点对点无线传输可以为电磁传输或光传输。无线传输模块111包括但不仅限于蓝牙模块、2.4G通讯模块、NFC模块、WIFI模块中的任意一种。
如图1所示，该LED显示单元110为矩形LED箱体，即LED显示单元110具体可以是矩形结构，该矩形LED箱体（包括矩形LED箱体框架112）的每一边均设置一无线传输模块111，两两相邻的LED显示单元110的相接边的两无线传输模块111形成一组相邻配对的无线传输模块111。这样一来，每两个相邻（无论是纵向相邻还是横向相邻）的LED显示单元110间都可进行信号双向传输。除此之外，该矩形LED箱体还包括置于矩形LED箱体框架112内的控制模块以及安设于矩形LED箱体框架112表面的LED模组。控制模块包含电源、接收卡、HUB板（转接板）等；电源和无线传输模块111都连接到HUB板上，HUB板上连接有接收卡，接收卡接收到从无线传输模块111传来的信号及数据，再将电源、信号及数据通过FPC软排线（或排针排母对插）输送给LED模组，以控制LED模组进行相应的画面显示。该LED显示单元110亦可采用无箱体框架形式，此时，该LED显示单元110即为矩形LED模组，该矩形LED模组的每一边均设置一无线传输模块111，两两相邻的LED显示单元110的相接边的两无线传输模块111形成一组相邻配对的无线传输模块111。
对于本领域技术人员而言，LED显示单元110可以是本实施例中的可以进行无限拼接的矩形结构，其四边均设置有无线传输模块111，亦可如图2所示，为可以进行无限拼接的三角形结构，即该LED显示单元210为三角形LED箱体（包括三角形箱体框架212）或三角形LED模组，且三边均设置有无线传输模块211，或者为其它可以进行无限拼接的正多边形箱体结构，即如图3所示，该LED显示单元310为正六边形LED箱体（包括正六边形LED箱体框架312）或正六边形LED模组，且六边均设置有无线传输模块311。这样使得本LED显示单元也可拼接成异形屏，且可避免现有异形屏接线繁琐、影响美观的问题。
另外，为满足本拼接显示屏的显示需求，拼接显示系统还包括信号源模块（未图示），信号源模块与任一LED显示单元110的无线传输模块111进行无线数据连接。理论上，任一LED显示单元110都可作为显示屏阵列100的信号输入装置，但基于显示屏阵列100的布局，优选采用位于显示屏阵列100的各个边沿的LED显示单元110作为显示屏阵列100的信号输入装置为好，这是因为，位于中间的LED显示单元110其上下左右四个无线传输模块111均与相邻的LED显示单元110的无线传输模块111进行配对了，如果要作为信号输入装置，则需额外增设一个无线传输模块111，容易造成成本增加。同时，本实施例的显示屏阵列100可接入多个信号源，多个信号源可来自一个信号源模块或多个信号源模块。显示屏阵列100的各个LED显示单元110皆可输出数据用于监控显示屏工作状态。信号源模块具体可包括主信号源单元与备用信号源单元，主信号源单元与一LED显示单元110的无线传输模块111进行无线数据连接，以实现显示屏阵列100的主信号输入。备用信号源单元与另一LED显示单元110的无线传输模块111进行无线数据连接，以实现显示屏阵列100的备用信号输入。这样一来，当主信号源单元、某一LED显示单元110、某一无线传输模块111等发生故障时，本实施例的显示屏阵列100可自动实现快速检测、定位并快速更改显示屏信号传输路径，通过多个无线传输模块带来的高冗余度，大幅提高了显示屏数据传输的可靠性。
实施例二
如图4所示，本发明实施例二提出一种信号控制方法，基于上述实施例一的拼接显示系统100，该信号控制方法具体包括以下步骤：
步骤S110：两两相邻的LED显示单元之间通过一组相邻配对的无线传输模块进行信号双向传输。
具体地，如图5所示，将多个LED显示单元110拼接成3*3的显示屏阵列100，信号A为主信号，信号B作为备用信号。两两相邻的LED显示单元110之间通过一组相邻配对的无线传输模块111进行信号双向传输，以在显示屏阵列100中形成网格型信号传输网络。系统基于每一LED显示单元110的位置自动为每一LED显示单元110分配相应的地址。
步骤S120：根据主信号源单元的工作状况自动切换显示屏阵列的信号输入。
具体地，如图6所示，执行本步骤“根据主信号源单元的工作状况自动切换显示屏阵列的信号输入”的具体过程包括：
步骤S121：若主信号源单元正常工作，则切断备用信号源单元的信号输入，以主信号源单元对显示屏阵列进行信号输入。
步骤S122：若主信号源单元非正常工作，则切断主信号源单元的信号输入，以备用信号源单元对显示屏阵列进行信号输入。
即如图5所示，信号A正常时，信号B处于切断状态，信号A作为显示屏阵列100的信号输入。而当信号A出现故障时，自动切换信号B作为显示屏阵列100的信号输入。
步骤S130：根据当前显示屏阵列的信号输入以及每一LED显示单元的工作状况，自动调整每一LED显示单元的信号最优传输路径，以控制相应的LED显示单元进行画面显示。
具体地，由于接入主信号源单元的LED显示单元110并非接入备用信号源单元的LED显示单元110，因而，当显示屏阵列100的当前信号输入发生改变时，其每一LED显示单元的信号最优传输路径亦会发生相应的调整，具体为如图7所示，执行步骤“根据当前显示屏阵列的信号输入自动调整每一LED显示单元的信号最优传输路径”的具体过程包括：
步骤S131：若以主信号源单元对显示屏阵列进行信号输入，则以连接主信号源单元的LED显示单元作为路径计算基准，自动调整每一LED显示单元的信号最优传输路径。
步骤S132：若以备用信号源单元对显示屏阵列进行信号输入，则以连接备用信号源单元的LED显示单元作为路径计算基准，自动调整每一LED显示单元的信号最优传输路径。
另外，除了当显示屏阵列100的当前信号输入发生改变时，其每一LED显示单元110的信号最优传输路径需要发生相应的调整外，当某个LED显示单元110如（2,2） 出现故障进行维护时，为了不影响其他LED显示单元110的正常显示，需在设置其余的每一LED显示单元110的信号最优传输路径时，绕开该故障的LED显示单元110，即执行步骤“根据每一LED显示单元的工作状况自动调整每一LED显示单元的信号最优传输路径”的具体过程包括：若任一LED显示单元非正常工作，则绕开非正常工作的LED显示单元，自动调整每一LED显示单元的信号最优传输路径。当（2,2）LED显示单元110维护完成后，可根据实际需要再一次调整每一LED显示单元的信号最优传输路径，以恢复整屏显示。
可见，常规显示屏在出现上述故障就会一排或一列箱体完全不亮甚至整屏不亮，而本申请的多路径（本实施例具体为四向）无线传输的显示屏阵列100的信号传输可靠性大幅提高，多个信号传输端口也决定了显示屏阵列100的传输路径的高冗余度。
步骤S140：若显示屏阵列同时进行多路信号输入时，自动为每一路信号输入分配用于相应画面显示的LED显示单元的地址，确定每一LED显示单元的信号最优传输路径，以控制相应的LED显示单元进行画面显示。
具体地，当本实施例中的显示屏阵列100需要显示多路信号时，即同时进行多路信号输入，为确保每一路信号输入均可正常显示，其需自动为每一路信号输入分配用于相应画面显示的LED显示单元100的地址，确定接入每一路信号输入的LED显示单元100的地址，进而在根据各个LED显示单元100之间的位置关系智能确定每一LED显示单元100的信号最优传输路径，以控制相应的LED显示单元进行画面显示，快速连屏。当某个LED显示单元100或某个无线传输模块111出现故障时，可智能重新调整每一LED显示单元100的信号最优传输路径。可见，本实施例中的显示屏阵列100可输送多路信号实现屏体多信号源分区域同时显示，无需矩阵切换器设备便可实现矩阵的功能。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
 工业实用性
本发明实施例中的拼接显示系统及其控制方法，其拼接显示系统包括显示屏阵列，显示屏阵列包括若干拼接在一起的LED显示单元，每一LED显示单元包括若干无线传输模块，两两相邻的LED显示单元之间通过一组相邻配对的无线传输模块进行信号双向传输，以在显示屏阵列中形成网格型信号传输网络。这样一来，显示屏阵列的LED显示单元之间无需人工连接数据线，装屏效率得到大大提升，同时，LED显示单元之间的信号传输路径从单向或双向变成多向多路径传输的网格型信号传输网络，多个数据传输端口、高冗余度、响应速度快，可快速点亮显示屏阵列，且单个LED显示单元的故障不会影响整个显示屏的画面显示，发生故障时自动调整信号最优传输路径、可靠性高。可见，本技术方案，其可有效解决现有LED显示屏接线繁琐、人工操作效率低下以及显示屏的显示容易受到单一箱体、线材、接插件等故障影响导致的低可靠性等问题。因此，具有工业实用性。
