具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
目前，现有旋转扫描LED显示设备，无法显示实时图像或者动画，需要将显示的图像或者动画提前下载到显示设备中，不能满足多样的显示需求。基于此，本发明实施例提供的一种提供旋转扫描LED显示系统和装置，不仅可以通过控制核心板将视频信号发送给旋转显示设备，还可以通过视频接口转换板的通用视频接口将外部设备的视频信号发送给旋转显示设备，可以显示实时图像或者动画，从而满足多种显示需求。
为便于对本实施例进行理解，首先对本发明实施例所公开的一种旋转扫描LED显示系统进行详细介绍。
如图1所示，本实施例提供了一种旋转扫描LED显示系统，包括旋转显示设备10、控制核心板20和视频接口转换板30，视频接口转换板30包括通用视频接口31；
控制核心板20，与旋转显示设备10相连接，配置成将视频信号发送给旋转显示设备10；
具体地，如图2所示，控制核心板20包括处理器21以及分别与处理器21相连接的无线通信模块22、第三串行通信接口23、第三高速串行接口24以及存储器26；存储器26配置成存储视频数据。其中，处理器21通过第二并串数据转换模块25与第三高速串行接口24相连接。处理器21可以采用ARM芯片，控制核心板20通过第三串行通信接口23或者第三高速串行接口24与旋转显示设备10相连接；处理器21通过无线通信模块22连接外部设备，以接收外部设备发送的视频数据或操作指令。无线通信模块22可以采用WiFi/蓝牙模块等。
控制核心板20为整个系统的控制核心，采用低功耗设计，可用电池供电，通过电池管理电路27进行管理，也可以外接电源。控制核心板20的核心是可以采用一块ARM内核处理器21，其外设包含WiFi/蓝牙模块，可与外部智能设备连接，从而接收视频文件以及操作指令。该ARM处理器21通过第三串行通信接口23向与其连接的旋转显示设备10传递控制指令，通过并串数据转换模块将视频流转为串行数据，再利用第三高速串行接口24将视频数据发送至与其连接的旋转显示设备10。
视频接口转换板30，与旋转显示设备10相连接，配置成通过通用视频接口31获取外 部视频信号，并将外部视频信号发送给旋转显示设备10。
进一步地，如图3所示，视频接口转换板30包括第一并串数据转换模块33，第一并串数据转换模块33配置成将通用视频接口31转换为第二高速串行接口34；视频接口转换板30通过第二高速串行接口34与旋转显示设备10相连接。另外，视频接口转换板30还包括USB转串口模块35，USB转串口模块35配置成将USB接口32转换为第二串行通信接口36；视频接口转换板30通过第二串行通信接口36与旋转显示设备10相连接。视频接口转换板30在连接至旋转显示设备10后，可将其第二串行通信接口36转换为USB接口32、将其第二高速串行接口34转换为通用视频接口31，可供用户通过电脑连接到旋转显示设备10，直接控制显示。
本实施例的旋转扫描LED显示系统通过视频接口转换板30的通用视频接口31，使得视频可以由外部设备(例如PC)直接通过视频接口连接至旋转显示设备10，所播放的视频可以直接由外部设备实时传输控制，不需要经过WiFi或是其他介质传输视频到旋转显示设备10。相比于传统先将视频下载至设备再播放的模式，本系统实时性强，扩展性强，可以配合外部设备实现实时人机交互和互动。同时，通用视频接口31采用有线视频输入，相比于通过无线方式实时传输视频流的技术，如RTSP(Real Time Streaming Protocol，实时流传输协议)，实时性可以得到保证，显示画面不会存在延迟，且传输很难受到干扰，可靠性高。
进一步地，如图4所示，旋转显示设备10包括依次相连接的电机驱动板11、电机12、数据处理板13以及LED灯板14，其中，电机驱动板11与数据处理板13相连接。电机12可以采用无刷电机。
进一步地，电机驱动板11上设置有激光发射管17，数据处理板13上设有激光接收管18，数据处理板13与电机驱动板11之间通过激光对管进行无线通信。另外，所述数据处理板与所述电机驱动板之间还可以通过互相耦合的电感、互相耦合的天线、红外光对管或者可见光对管进行无线通信。
优选地，激光发射管17和激光接收管18可以采用双波长激光，从而在底板和旋转端之间实现双向的高速通信。这样，可以避免利用无线供电线圈调制信号传输低速控制信号。
采用互相耦合的电感，使用磁场感应传输显示数据，具体为，将对射的激光收发管替换为互相耦合的电感，同时将激光收发的前端电路替换为与耦合电感相匹配的信号放大/整形电路；采用互相耦合的天线，将串行视频信号直接通过电磁波辐射传输到旋转端；采用普通红外光或可见光替代激光传输(设置红外光对管或可见光对管)等等；还可以采用滑环或集电环传输高速显示数据，例如普通电刷滑环或液态金属滑环或光纤滑环。
具体地，电机驱动板11为静置部分，电机12、数据处理板13以及LED灯板14为旋 转部分，由于静置部分与旋转部分采用激光设备传输数据，其数据采用串行方式传输，带宽非常大，能够实时将通用视频接口31输入的超大视频流数据传输到旋转显示部分，使得旋转显示设备10可以实时显示由通用视频接口31输入的图像。
进一步地，电机驱动板11上设置有第一串行通信接口、第一高速串行接口、镜像串行通信接口以及镜像高速串行接口；镜像串行通信接口以及镜像高速串行接口配置成进行设备级联。并且，当需要设备和设备级联时，每个设备接收到的都是实时且同步的图像数据，所以，可以方便扩展联屏。通过控制级联的不同设备显示画面的不同区域，可实现实时画面拼接显示，扩大显示面积。
进一步地，旋转显示设备10采用无线供电方式，电机驱动板11包括无线供电发射电路，数据处理板13包括无线供电接收电路。另外，无线供电发射电路包括调制模块，无线供电接收电路包括解调模块，旋转显示设备通过调制模块以及解调模块进行数据通信。从而在无线传输电能的同时加入调制信号，实现部分低速控制信号的传输。
其中，电机驱动板11实现电机12的驱动和无线供电发射线圈15的控制。同时，由于电机12、数据处理板13以及LED灯板14在工作时均处于旋转状态，用户无法直接操作，而电机驱动板11一直处于静止状态；因此在电机驱动板11上还可以设置一些基本的功能按钮，还可以预留了一个通信用串口，配置成接收复杂控制信号。电机驱动板11还包括一个高速串行接口，该接口接收视频信号，数据处理板13与电机驱动板11之间采用激光传输实现无线通讯。另外该板还包含两个镜像接口，配置成设备的级联拓展。数据处理板13利用转速检测传感器获取设备的旋转状态，可据此确定画面的显示角度。数据处理板13上有激光通信管的接收端，用串-并数据转换器将视频信号恢复成并行，由FPGA(Field-Programmable Gate Array，现场可编程门阵列)接收，并配置成驱动LED灯板14显示图像。
具体地，LED灯板包括依次相连接的LED驱动电路、LED阵列以及色彩校正模块；LED驱动电路配置成驱动LED阵列显示色彩，色彩校正模块存储有色彩校正信息。LED灯板为一列线阵LED灯珠，与数据处理板连接，数据处理板通过LED驱动电路驱动LED阵列显示24位RGB色彩；另外，LED灯板还包括存储模块，保存了颜色校正信息，可以供数据处理板读取该信息，并根据该信息调节色差。
LED板的灯珠数可根据设备型号及需求不同，在一定范围内配置，从而实现不同分辨率画面的显示，同时内置存储芯片，配置成保存颜色校正信息，进而校正LED灯珠的不一致性，提高显示质量。
具体地，电机驱动板11包括单片机、与单片机相连接的电机12驱动器、第一串行通信接口、镜像串行通信接口、第一高速串行接口、镜像高速串行接口、按键、无线供电发 射电路、电源及保护电路，电源及保护电路连接有电源适配器；电机驱动板11的电机12驱动器与电机12相连接；数据处理板13包括FPGA、与FPGA相连接的转速检测传感器、串并数据转换接口、无线供电接收电路，转速检测传感器检测电机12的转速，具体可以采用霍尔传感器，无线供电接收电路与电机驱动板11的无线供电发射电路无线连接；LED灯板14包括相互连接的LED驱动电路和LED阵列，LED驱动电路与数据处理板13的FPGA相连接。
具体地，旋转显示设备10的数据处理板13采用一片FPGA实现图像由直角坐标到旋转坐标之间的转换，同时实现LED驱动芯片的控制，以及LED亮度曲线的校正。需要显示的图像由激光传输再经串-并数据转换获得，直接传输至FPGA。根据需求的不同，FPGA将位图数据缓存在FPGA内置存储区或外置RAM中。采用一个霍尔传感器检测旋转部分当前角度，FPGA通过查找正弦表，进一步获得当前位置上，每一个LED对应像素在缓存中的位置。从而从缓存中读取该像素的颜色数据(RGB值)，以实现坐标系统的实时转换。为实现高质量颜色显示，像素点的颜色信息还需经过Gamma校正、中心亮度校正及LED不一致性校正后才送到LED驱动芯片。本系统中，LED芯片的亮度曲线校正由FPGA通过存储在片上的查找表实现。例如，每个像素RGB值的灰度范围为0-255；LED驱动芯片PWM位数为13位，通过查找一个大小为13*256的查找表，可以得到每一个灰度值对应的PWM数值。
由于旋转显示自身的特性，处于较小旋转半径上的LED，其旋转一圈过程中由于行程较短，呈现的亮度将大于处于较大半径上的LED如果不加校正，会导致图像中心偏亮，边缘偏暗的情况，严重影响图像显示质量。本系统中，使用FPGA实现中心亮度偏亮的校正。具体方式为将经过Gamma校正的亮度信息，根据LED位置不同乘上不同的亮度校正系数。位置靠中心的LED亮度校正系数较小，靠侧边的亮度校正系数较大。
由于LED生产过程中存在一定的不一致性，每颗灯珠的R/G/B亮度均存在一定差异，会导致显示图像时产生色差。本系统中设有LED色彩校正功能。具体实现方式是，在生产过程中，增加校色环节。先将每颗LED设定为一样的亮度，读取LED灯条上每颗LED的红色/绿色/蓝色亮度，从中找出最小亮度的LED，并将其他LED与该LED亮度的比例经过计算和处理后存储到灯条上的EEPROM中。设备正常运行时，FPGA在初始化过程中，读取EEPROM中的数据，获得每颗LED的红/绿/蓝颜色亮度增益并保存在内存中。现称之为校准增益。在FPGA完成Gamma校正和图像中心亮度校正后，输出的数据进一步乘上此处的校准增益，然后将最终数据发送给LED驱动芯片。从而实现对LED不一致性的校准。
进一步，由于中心亮度校准和LED不一致性校准都是一次乘法计算，为减小FPGA的硬件资源消耗，可将中心亮度校正系数与LED校准增益事先处理并存在灯条EEPROM中。 设备工作时只需一次计算即可完成两种校正。
本系统中图像数据可经由两种途径产生，分别对应两种扩展板：控制核心板20以及视频接口转换板30。当使用控制核心板20时，图像的传输采用该扩展板上的wifi模块实现。图像和视频可以由PC机或手机，通过wifi发送至旋转显示设备10，并存储在板载Flash或存储卡中，在需要的时候播放。实时视频流也可以通过wifi传输至设备，由处理器21解码后，向旋转显示设备10部分输出视频流数据，实现无线实时显示。
当使用视频接口转换板30时，外部视频源(如PC机)直接通过通用视频接口31与扩展板连接，将视频流直接上传到旋转显示设备10中，实现实时画面显示，此时本系统可以当做普通扩展屏幕使用。
如图5所示，本实施例还提供了一种旋转扫描LED显示装置，包括上述旋转扫描LED显示系统，系统的控制核心板20以及视频接口转换版分别与旋转显示设备10可拆卸连接。
进一步地，旋转显示设备10包括设置在底部的电机驱动板11，电机驱动板11的上面依次设置有无线供电发射线圈15、电机12、无线供电接收线圈16、数据处理板13以及LED灯板14；
电机驱动板11与数据处理板13之间设置有无线通信装置。
可选地，控制核心板20或视频接口转换版与旋转显示设备10使用螺丝固定，电机驱动板11、无线供电发射线圈15、无线供电接收线圈16、电机12、数据处理板13以及LED灯板14也可以使用螺丝固定，不需要专门的固定结构。
为了实现旋转显示设备10的供电，本实施例采用无线供电方式，具体为两个相互耦合的无线供电线圈，线圈周围采用吸波材料或铁氧体材料进行磁屏蔽，减小对外界的干扰，并提高无线供电效率。在线圈传输电能的同时加入调制信号，实现部分低速控制信号的传输。
具体地，无线通信装置实现实时视频流由静止的底板到旋转部分的数据传输，无线通信装置可以采用激光对管，此时，所采用的电机12使用空心轴承，电机驱动板11和数据处理板13上分别设置有激光发射管17和激光接收管18，如图6所示，相对置于电机12圆心位置的空心轴承中，轴承的底板端安装激光发射管17，旋转端安装激光接收管18。利用该管带宽大、非接触的特性，实现无线传输视频流数据，从而解决了高速视频流传输的问题，进而实现实时画面的显示。
优选地，激光发射管17和激光接收管18可以采用双波长激光，从而在底板和旋转端之间实现双向的高速通信。这样，可以避免利用无线供电线圈调制信号传输低速控制信号。
另外，除了采用激光对管传输显示数据外，还可以采用以下方式：
采用互相耦合的电感，使用磁场感应传输显示数据，具体为，将对射的激光收发管替换为互相耦合的电感，同时将激光收发的前端电路替换为与耦合电感相匹配的信号放大/整形电路；采用互相耦合的天线，将串行视频信号直接通过电磁波辐射传输到旋转端；采用普通红外光或可见光替代激光传输等等；另外，还可以采用滑环或集电环传输高速显示数据，例如普通电刷滑环或液态金属滑环或光纤滑环。
