显示屏通过多个箱体拼接而成,而箱体又是由多个显示模组拼接而成,模组PCB上包含控制驱动IC等。箱体需要播放视频信息,现有的一个基本结构是需要将视频信息通过发送卡发送,箱体中的接收卡接收,接收完毕后,通过排线发送到各个模组上。箱体与箱体之间通过网线连接,视频信号在箱体与箱体之间通过网线传输。这样一来,视频信号就可实现模组与模组之间的传输和实现箱体与箱体之间的传输,这也是现有的一个显示屏信号传输流程。
基于以上这种信号传输方式,存在有以下问题:(1)模组与模组之间的排线连接,会占据箱体内部大量空间,不利于屏体的轻薄化。
(2)模组与模组之间的排线连接和箱体与箱体之间的网线连接接线复杂,不利于拆装维护,容易因接触不良产生断路,影响箱体的稳定性。
(3)箱体与箱体之间的网线连接,要求箱体与箱体之间需要存在一个开口通道供出线,不利于箱体良好的密封性。
(4)基于该通讯体系下的信号控制、系统调试比较复杂,不但需要软件层面的参数设置,路径设置等,还需要兼顾硬件层面的线路连接、箱体位置、接线方式、接线位置等多种因素。
(5)多路串口接线对环境要求较高,需要箱体具有较好的气密性和防水性能。

附图说明
图1为本发明提供一种显示屏通信系统的结构示意图;图2为本发明提供一种箱体的结构示意图;图3为本发明提供一种显示屏通信方法的流程示意图。
本发明目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。
本发明的实施方式
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白,以下结合附图和实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅以解释本发明,并不用于限定本发明。
在后续的描述中,使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明,其本身没有特定的意义。因此,“模块”、“部件”或“单元”可以混合地使用。
在一个实施例中,如图1所示,本发明提供一种显示屏通信系统,所述通信系统包括:一个信号站10和若干箱体20拼接在一起的显示屏100,所述信号站10与若干箱体20呈星形通信结构建立无线通信连接进行信息的无线信号传输,所述信号站10驱动若干所述箱体20,所述箱体20之间通过无线方式进行无线信号传输;其中,所述信息包含控制信息、视频信息、箱体的位置信息、以及箱体的播放坐标值中的一种或任意多种。
在本实施例中,所述显示屏由多个箱体拼接而成,而箱体由多个显示模组拼接而成,每个箱体就是一个播放单元,每个箱体都能够播放视频和音频。所述显示屏通信系统应用无线连接相关技术,通过一个信号站对多个箱体统一进行包含控制信息、视频信息和位置信息等所需信息的无线信号传输,能够使箱体无需使用排线、网线等类似结构的有线连接方式进行信号传输,而使用无线传输形式进行视频信号等传输,节省箱体内空间,箱体结构更简单、变得更加轻薄,箱体控制线路和控制逻辑得到简化,确保了通信更加流畅及时,更方便;无线连接形式省略了大量串口,进一步简化显示屏的信息流通渠道与连接方式,有利于拆装维护的方便。
优选地,所述显示屏100为LED显示屏,所述箱体20为LED箱体。
在一个实施例中,所述信号站10与若干箱体20呈星形通信结构建立无线通信连接进行信息的无线信号传输,进一步包括:所述信号站10集成所述箱体20内的模组原有的信息处理和信息发送,具有信息发送和信息处理的功能,实现所述箱体20的模组原先的信息发送、信息处理。所述箱体20的模组只保留信息接收,仅通过接收信息实现视频播放和音频播放。
所述信号站10与若干箱体20组成星形通信结构,通过所述信号站10统一对多个箱体20进行信息的无线信号传输。
在本实施例中,将每个箱体的模组的信息处理和信息发送都集成在一个信号站上,模组上仅保留信息接收,仅需要实现视频播放和音频播放,信息发送、信息处理(例如信息的承接、编码、放大和存储)等被集成在一个信号站上,通过一个信号站驱动多个箱体模组。同时,通过一个所述信号站统一对多个箱体进行信号传输,由于所述信号站与若干箱体是组成星形通信结构,而不是串联结构,即使其中出现一路箱体故障,也不会影响到其他箱体的正常工作,从而实现更稳定的显示效果。
在一个实施例中,所述无线传输通信技术至少包括以下之一:LiFi(Light  Fidelity,可见光无线通信或光保真技术)形式或WiFi形式进行无线信号传输。
需要说明的是,本发明的无线传输通信技术不限于以上提到的两种无线传输技术,凡是能进行无线信号传输的信息的技术皆涵盖在此范围内。
在一个实施例中,如图2所示,所述箱体20包括无线通信装置21,所述无线通信装置21用于箱体20与箱体20之间,以及箱体20与所述信号站10进行无线信号通信。
在一个实施例中,如图1和图2所示,所述箱体20包括电力输送装置22,所述电力输送装置22用于与设置在显示屏100中央的供电装置30进行电力传输,为所述箱体20和无线通信装置21提供电源。
所述电力输送装置可选的包括软连接形式、硬连接形式、有线或无线形式等,安置与箱体的边沿,在保证箱体密封性良好的情况下,使得箱体的结构简单、轻薄,系统的控制逻辑和布线逻辑都能够得到化简。
在一个实施例中,所述箱体20包括一个箱体编码,所述箱体编码用于标识所述箱体。所述箱体20在出厂时会有一个独一无二的箱体编码,该箱体编码在支持无线传输的整块显示屏100中是唯一的。
在本实施例中,箱体与箱体无需进行紧密连接。因为箱体与箱体之间以及箱体与信号站之间采用无线通信装置进行无线信号通信,箱体与箱体之间的通电形式可变为在箱体边框接插硬连接形式,使得箱体的边沿处接缝是可调的,而不影响信号和供电,所以允许箱体可不需要紧密相连。箱体与箱体之间的拼接仅仅通过连接卡扣等装置即可完成,完全无走线也支持无开孔,拆装方便。
本发明实施例还提供一种显示屏通信方法,应用于上述无线通信系统的信号站,所述方法包括:信号站获取显示屏的箱体的初始化信息,与各箱体建立星形通信结构的无线通信连接;与显示屏的各箱体进行信息的无线信号传输。
在一个实施例中,所述信号站与若干箱体建立星形通信结构的无线通信连接包括:所述信号站与若干箱体呈星形通信结构建立初始化无线通信连接。
在一个实施例中,所述信号站与若干箱体呈星形通信结构建立初始化无线通信连接,至少包括以下之一方式建立初始化无线通信连接。
方式一、所述信号站通过手动方式获取显示屏的箱体的初始化信息,建立初始化无线通信连接。包括:A1、信号站接收通过手动方式录入显示屏的箱体的初始化信息,其中,所述初始化信息包括:箱体数量、箱体编码、箱体安装位置。
A2、所述信号站获取显示屏的箱体的初始化信息后,依据箱体编码代表的相应次序,对显示屏划分播放区域,为拼接成所述显示屏的每个箱体分配播放坐标值。
至此,所述信号站与若干箱体建立初始化无线通信连接。后续,所述信号站根据已建立的初始化无线通信连接,将全部视频信息发送给箱体,所述箱体接收信号站发送的全部视频信息,根据自身播放区域的播放坐标值来输出对应位置的视频信息。另外,所述信号站在通信过程中,由于保留有每个箱体的初始化信息,故可以对比箱体反馈信息来检测箱体是否出现故障情况,或未响应情况。
以上这种通过手动录入箱体初始化信息到信号站的手动录入方式虽然比较麻烦,但是可以避免可能出现信号的冲突的问题,即可以避免信号站可能会出现同时面对两个箱体进行通信和指令,影响整体控制逻辑,容易出现错误的问题。
方式二、所述信号站通过自动方式获取显示屏的箱体的初始化信息,建立初始化无线通信连接。
在这种工作形态下,箱体与箱体之间进行简单的信息通信,并将通信结果传输给信号站,使信号站自动获取箱体的初始化信息,建立初始化无线通信连接;所述初始化信息包括:箱体数量、箱体编码、箱体安装位置。具体包括:B1、信号站为显示屏的箱体打上标签。
具体的,当箱体拼接成显示屏时,所述信号站发出“报数”指令。每个箱体在响应所述信号站报数指令之前,根据自身的箱体编码,按照预设的编译规则生成一个延迟响应值,并根据这一延迟响应值响应所述信号站指令。由于每个箱体的箱体编码是唯一的,所以生成的延迟响应值也是唯一的,对于整块显示屏来说,不会出现两个箱体的延迟响应值冲突的情况,在一次箱体与信号站相互通信时,仅存在一个箱体与所述信号站进行通信,从而可以避免可能出现信号的冲突的问题,即可以避免信号站可能会出现同时面对两个或以上箱体进行通信和指令,影响整体控制逻辑,容易出现错误的问题。
整块显示屏的箱体与箱体之间进行一个信号交流,根据每个箱体的延迟响应值按照预设排序规则确定响应所述信号站报数指令的响应优先次序,并确定拥有第一响应优先权的箱体,从而使每个箱体都知道自已的响应优先次序。优选地,所述预设排序规则为将延迟响应值从小到大排序,延迟响应值越小,响应优先次序越高。
箱体根据确定的响应优先次序,依次响应所述信号站指令。具体包括:拥有第一响应优先权的箱体优先响应来自所述信号站的报数指令。如果拥有第一响应优先权的箱体无法响应来自所述信号站的指令,即信号站读取不到这一响应优先次序下的箱体信息,那么会判断第一响应优先次序的箱体存在故障,则修改优先级至下一响应优先次序,让下一响应优先次序的箱体进行响应。直至所有确定响应优先次序的箱体都响应所述信号站指令。
所述信号站根据箱体的响应,自动获取箱体的初始化信息,为显示屏的箱体打上标签。
具体的,所述信号站接收根据响应优先次序的箱体响应来自所述信号站的指令的信号,与所述箱体建立一条信息交互的信道。
所述信号站对剩下未响应的箱体发送“待机”指令,让其等待信号站的进一步指令。

B213、检测周围箱体的标签值,并进行记录。
上述开机自检流程完成后,箱体进入待机状态,此时才会响应信号站的指令。
通过以上开机自检流程,箱体除了可以检测自身的状态之外,还可以检测记录周围箱体的标签值,从而可以统计附近周围箱体的标签信息。

B332、所述信号站确认收到的所述箱体编码无误后,向所述箱体发送该箱体编码对应播放坐标值信息。
B333、所述信号站向所述箱体输入睡眠指令。
至此,信号站完成对第一个箱体赋播放坐标值。
依据上述流程对之后每一个箱体都赋对应的播放坐标值。
在所述信号站发出“赋值”指令时,没有箱体再响应信号站的“赋值”指令时,说明所述信号站已对全部箱体赋值完成,或者仅依据程序判别确定对全部箱体赋值完成。
在一个实施例中,所述信号站与若干箱体呈星形通信结构建立初始化无线通信连接进行信息的无线信号传输,包括:B4、信号站根据已建立的初始化无线通信连接,发送全部视频信息给所有箱体。

要强调的是,箱体存在不响应信号站的情况,即在箱体故障时,会出现不同程度的不响应情况,分别是:不响应信号站指令、单个方向不响应箱体通信、多个方向不响应箱体通信和完全不响应。
当箱体不响应信号站通信时,可以通过“B21、箱体统计附近周围箱体的标签信息”这一流程来识别,当这个箱体不响应信号站的指令时,信号站就会跳过这一箱体,去标记下一箱体,因此故障箱体是不具备标签信息的。
如果该箱体在至少一个方向上能够进行箱体通信,就可以把这个未得到信号站标记的箱体识别出来,信号站可以通过故障箱体周围的箱体来识别箱体的故障情况,并且判断出改故障箱体的具体位置。
如果箱体完全不响应,意味着周围箱体完全无法读取来自故障箱体的任何信息,对于整屏和信号站来说,这一箱体不存在。但是在信号站拟合的屏体中,这一块区域由于读取不到信息,即对于故障箱体的其周围箱体来说,面向故障箱体这一面的信息是缺失的,所以播放坐标上会有所区别。
在一个实施例中,如图3所示,本发明提供一种显示屏通信方法,应用于上述显示屏通信系统的显示屏,所述方法包括:S1、显示屏的若干箱体与信号站建立星形通信结构的无线通信连接,进行信息的无线信号传输;S2、所述箱体之间通过无线方式进行无线信号传输。
具体的,显示屏通信系统应用无线连接相关技术,通过一个信号站对多个箱体统一进行无线信号传输。其中,信息包括但不限于控制信息、视频信息、箱体的位置信息、箱体的播放坐标信息等所需的一种或任意多种组合信息。所述信号站集成所述箱体内的模组原有的信息处理和信息发送,具有信息发送和信息处理的功能,实现所述箱体的模组原先的信息发送、信息处理。所述箱体的模组只保留信息接收,仅通过接收信息实现视频播放和音频播放。
在本实施例中,将每个箱体的模组的信息处理和信息发送都集成在一个信号站上,模组上仅保留信息接收,仅需要实现视频播放和音频播放,信息发送、信息处理(例如信息的承接、编码、放大和存储)等被集成在一个信号站上,通过一个所述信号站统一对多个箱体进行信号传输,由于所述信号站与若干箱体是组成星形通信结构,而不是串联结构,即使其中出现一路箱体故障,也不会影响到其他箱体的正常工作,从而实现更稳定的显示效果。在一个实施例中,所述无线传输通信技术至少包括以下之一:LiFi形式或WiFi形式进行无线信号传输。
需要说明的是,本发明的无线传输通信技术不限于以上提到的两种无线传输技术,凡是能进行无线信号传输的信息的技术皆涵盖在此范围内。
在一个实施例中,所述箱体包括无线通信装置;所述箱体通过所述无线通信装置与所述信号站建立无线通信连接,进行无线信号传输。所述箱体之间通过所述无线通信装置进行无线信号传输。
在一个实施例中,所述箱体包括一个箱体编码,所述箱体编码用于标识所述箱体。所述箱体在出厂时会有一个独一无二的箱体编码,该箱体编码在支持无线传输的整块显示屏中是唯一的。在一个实施例中,所述步骤S1包括:所述若干箱体与信号站建立星形通信结构的初始化无线通信连接。至少包括以下之一方式建立初始化无线通信连接:方式一、所述信号站通过手动方式获取显示屏的所有箱体的初始化信息,建立初始化无线通信连接。S111、接收通过手动方式录入显示屏的所有箱体的初始化信息,其中,所述初始化信息包括:箱体数量、箱体编码、箱体安装位置坐标。
S112、获取显示屏的所有箱体的初始化信息后,依据箱体编码代表的相应次序,对每个箱体进行划分显示屏的播放区域,为每个箱体分配播放坐标值。
至此,所述信号站与若干箱体建立初始化无线通信连接。后续,所述信号站根据已建立的初始化无线通信连接,将全部视频信息发送给所有箱体,所述箱体接收信号站发送的全部视频信息,根据自身的播放坐标值(播放区域)来只输出对应位置的视频信息。另外,所述信号站在通信过程中,由于保留有每个箱体的初始化信息,故可以对比箱体反馈信息来检测箱体是否出现故障情况,或未响应情况。
方式二、所述信号站通过自动方式获取显示屏的箱体的初始化信息,建立初始化无线通信连接。
在这种工作形态下,箱体与箱体之间进行简单的信息通信,并将通信结果传输给信号站,使信号站自动获取箱体的初始化信息,建立初始化无线通信连接;所述初始化信息包括:箱体数量、箱体编码、箱体安装位置坐标。具体包括:S121、信号站为显示屏的箱体打上标签。包括:当箱体拼接成显示屏时,所述信号站发出“报数”指令。
每个箱体在响应所述信号站报数指令之前,根据自身的箱体编码,按照预设的编译规则生成一个延迟响应值,并根据这一延迟响应值响应所述信号站指令。由于每个箱体的箱体编码是唯一的,所以生成的延迟响应值也是唯一的,对于整块显示屏来说,不会出现两个箱体的延迟响应值冲突的情况,在一次箱体与信号站相互通信时,仅存在一个箱体与所述信号站进行通信,从而可以避免可能出现信号的冲突的问题,即可以避免信号站可能会出现同时面对两个或以上箱体进行通信和指令,影响整体控制逻辑,容易出现错误的问题。
整块显示屏的箱体与箱体之间进行一个信号交流,根据每个箱体的延迟响应值按照预设排序规则确定响应所述信号站报数指令的响应优先次序,并确定拥有第一响应优先权的箱体,从而使每个箱体都知道自已的响应优先次序。优选地,所述预设排序规则为将延迟响应值从小到大排序,延迟响应值越小,响应优先次序越高。
箱体根据确定的响应优先次序,依次响应所述信号站指令。具体包括:拥有第一响应优先权的箱体优先响应来自所述信号站的报数指令。如果拥有第一响应优先权的箱体无法响应来自所述信号站的指令,即信号站读取不到这一响应优先次序下的箱体信息,那么会判断第一响应优先次序的箱体存在故障,则修改优先级至下一响应优先次序,让下一响应优先次序的箱体进行响应。直至所有确定响应优先次序的箱体都响应所述信号站指令。
所述信号站根据箱体的响应,自动获取箱体的初始化信息,为显示屏的箱体打上标签。包括:所述信号站接收根据响应优先次序的箱体响应来自所述信号站的指令的信号,与所述箱体建立一条信息交互的信道。
所述信号站对剩下未响应的箱体发送“待机”指令,让其等待信号站的进一步指令。

S1213、所述信号站向所述箱体输送一条睡眠指令,在未收到“启动箱体”指令时,不响应所述信号站任何其他形式的指令。
接下来,信号站会再一次输出“报数”指令,此时,拥有第一响应优先权的箱体进入睡眠模式,不会响应信号站指令,而原先拥有第二响应优先权的箱体会成为最优先权箱体,这个箱体会响应信号站,并重复上述操作。
通过以上的操作,对于整块显示屏来说,箱体会逐一接受所述信号站的响应指令,并被所述信号站打上标签。在整块显示屏中最后一个箱体也被打上标签后,信号站发出响应指令时,不会有箱体再回应,则信号站进入启动箱体的下一工作模式。
S122、信号站根据显示屏的箱体的标签信息获取箱体的物理安装位置。包括:S1221、箱体统计附近周围箱体的标签信息。包括:所述信号站会对全部箱体发出“启动箱体”指令。

S12213、检测周围箱体的标签值,并进行记录。
上述开机自检流程完成后,箱体进入待机状态,此时才会响应信号站的指令。
通过以上开机自检流程,箱体除了可以检测自身的状态之外,还可以检测记录周围箱体的标签值,从而可以统计附近周围箱体的标签信息。
S1222、信号站逐个接收箱体的周围标签信息。包括:所述信号站对全部箱体发出“启动箱体”指令,与箱体发起信号交流,获取箱体的标签信息及其周围箱体的标签信息。具体包括:所述信号站向第一个被打上标签值的箱体发起“问询”指令,并等待该箱体回应。
该被问询的箱体在进入待机状态时第一时间响应所述信号站的“问询”指令。具体的,当被问询的所述箱体响应所述信号站的问询指令时,所述箱体通过已建立信息交互的信道与所述信号站进行以下信息交流:S12221、所述箱体向所述信号站反馈箱体的标签值及其周围箱体的标签值。
S12222、所述信号站收到箱体发送的标签信息后,给箱体发送一个睡眠指令,在未收到“启动箱体”指令时,不响应所述信号站任何其他形式的指令。

S1223、信号站拟合所有获得的标签信息得到与标签信息对应的箱体在显示屏的物理安装位置。
包括:在所述信号站获取了全部箱体的标签信息及其周围箱体的标签信息后,通过预设的拟合算法将获取的全部标签拟合,得到每一标签所对应的箱体在整块显示屏中的物理安装位置信息。
S123、信号站根据显示屏的箱体的物理安装位置为显示屏的箱体分配播放坐标值。
S1231、信号站在得到每个标签对应的箱体在整块显示屏中的物理安装位置信息后,依据整块显示屏及标签数量对显示屏划分区域,划分出来的区域大小就是一个箱体的尺寸大小。
S1232、所述信号站对每个箱体进行编码,依次给每个箱体分配播放坐标值,该播放坐标值对应箱体的显示范围;其中,一个箱体标签对应两个确定的坐标值。
S1233、信号站逐个将箱体的播放坐标值发送给箱体。包括:在信号站对每个箱体完成编码并分配好播放坐标值后,向全部箱体输出“启动箱体”指令。

所述第一箱体在处于开机自检流程时不会及时响应该赋值指令,但在考级自检流程结束进入待机状态时,会第一时间响应该赋值指令,所述箱体通过已建立信息交互的信道与所述信号站进行以下信息交流:S12331、所述箱体向所述信号站发送其自身箱体编码信息。
S12332、所述信号站确认收到的所述箱体编码无误后,向所述箱体发送该箱体编码对应播放坐标值信息。

至此,信号站完成对第一个箱体赋播放坐标值。
依据上述流程对之后每一个箱体都赋对应的播放坐标值。
在所述信号站发出“赋值”指令时,没有箱体再响应信号站的“赋值”指令时,说明所述信号站已对全部箱体赋值完成,或者仅依据程序判别确定对全部箱体赋值完成。
在一个实施例中,所述步骤S1包括:S131、信号站根据已建立的初始化无线通信连接,发送全部视频信息给所有箱体。
所述信号站根据已建立的初始化无线通信连接,向全体箱体输出“启动箱体”指令。
