图6为本实施例提供的控制端的结构框图。
具体实施方式
本实施例提供了一种终端控制方法，通过Li-Fi(Light Fidelity，可见光无线通信，又叫光保真)技术实现多个智能终端的同步播放，Li-Fi技术是通过对于光线强度的调制(例如LED灯发出闪烁的光线)来传输数据。这种光的闪烁频率极高，肉眼是无法察觉的。只有光敏探测器才能检测到这种光线变化，然后将接收的光线转化成电信号的形式，解决了在无法使用Wi-Fi连接的情况下，多个智能终端无法实现同步播放的问题。
参见图1，本公开提出了一种终端控制方法，所述方法包括：步骤110-步骤130。
步骤110中，接收Li-Fi发射模块发射的Li-Fi光信号。
步骤120中，根据接收的Li-Fi光信号，获取对应的控制信息。
步骤130中，根据获取的控制信息，对终端进行控制。
其中，所述控制信息包括同步信息；
所述根据获取的控制信息，对终端进行控制包括：根据获取的同步信息，进行多媒体数据的展示。
本实施例中，在终端接收Li-Fi发射模块发射的Li-Fi光信号之后，如果终端当前处于使用状态，则停止根据接收的Li-Fi光信号获取对应的同步信息；在终端结束使用状态之后，执行根据接收的Li-Fi光信号，获取对应的同步信息的步骤。此外，如果终端不在使用状态时，也可以关闭接收Li-Fi光信号的功能。
参见图2，本公开提出了一种终端控制方法，所述方法包括：步骤210-步骤250。
步骤210中，控制端获取控制信息，该控制信息可以包括同步信息。
控制端可以预置并存储同步信息，也可以提供同步信息输入接口，实时接收用户输入的同步信息。
步骤220中，控制端根据获取的同步信息，驱动Li-Fi发射模块发射同步信息对应的Li-Fi光信号。
可选的，该步骤220，包括：将所述同步信息转换成Li-Fi光信号；以及驱动Li-Fi发射模块发射所述Li-Fi光信号。
其中，为了保证同步的实时性，控制端可以根据预定的时间间隔发送同步信息对应的Li-Fi光信号，例如，以1秒为间隔发送同步信息对应的Li-Fi光信号，或者，以1分钟为间隔发送同步信息对应的Li-Fi光信号。预定的时间间隔可以设置为0.5秒～100秒。
其中，Li-Fi发射模块可以包括LED光源和Li-Fi控制芯片。可选地，通过在LED光源中增加一个Li-Fi控制芯片，即可以进行Li-Fi信号的发射，可以通过N个LED光源中的Li-Fi控制芯片，实现时间信号的同步。其中，N为大于等于1的正整数。
LED光源可以是1个，也可以是多个，多个LED光源可以通过同一个Li-Fi控制芯片进行控制，也可以通过多个Li-Fi控制芯片进行控制。当所述多个LED 光源通过多个Li-Fi控制芯片进行控制时，可以是每个所述LED光源通过一对应的Li-Fi控制芯片进行控制。
在一实施例中，在Li-Fi控制芯片的前端增加电力信号的调制解调，电脑之类的控制端通过在电力信号中增加电力载波，加载时间信号，并将加载了时间信号的电力信号(即，同步信息)发送至Li-Fi控制芯片，Li-Fi控制芯片在接收到该电力信号后，获取该电力信号上加载的时间信号，将获取的时间信号转换成对应的Li-Fi信号加载到LED光源中并发射出去。
由于每个LED光源的作用范围限于该光源光线能够传播到达的地方，因此可能是局限在一个房间内，如果需要多个房间内的多个智能终端实现同步，可以设置多个LED光源，多个LED光源分别作用于不同的区域，多个LED光源保持Li-Fi信号的同步发射，从而实现多个不同区域内的多个智能终端的同步播放。
步骤230中，终端接收Li-Fi发射模块发射的Li-Fi光信号。
如果终端上设置有能够接收Li-Fi信号的硬件模块，该硬件模块为单独设置的传感器，则通过该硬件模块接收Li-Fi发射模块发射的Li-Fi光信号，如果终端上没有设置能够接收Li-Fi信号的硬件模块，可以通过camera(照相机)模块接收Li-Fi发射模块发射的Li-Fi光信号。
步骤240中，根据接收的Li-Fi光信号，获取对应的同步信息。
步骤250中，终端根据获取的同步信息，进行多媒体数据的展示。
例如，多个终端可以分别接收Li-Fi光信号，获取对应的同步信息；并根据获取的同步信息，进行在多个终端上的多媒体数据的同步展示。
本实施例中，同步信息包括播放进度、文件名、路径信息以及播放顺序信息中的至少一个。多媒体数据包括视频，照片，语音文件以及ppt文件等。
播放进度包括当前时间信息H：M：S，其中，H表示小时，M表示分钟，S表示秒，并读取演示内容的时长t(单位为秒)，根据获取的当前时间信息H：M：S和时长t，可以计算出当前的播放节点X＝(H*60*60+M*60+S)％t，因此，从第X秒开始播放，终端的演示模块持续获取同步信息，并且根据获取的同步信息持续调整播放进度。
终端在接收到播放进度时，根据所述播放进度对当前播放的视频源进行播放。终端在接收到文件名和播放进度时，根据所述播放进度对文件名对应的视频源进行播放。
终端在接收到文件名、路径信息以及播放顺序信息时，对路径信息下的文件按播放顺序信息设置的顺序进行播放，且播放的起点为文件名对应的多媒体数据。
通过上述方法，多个手机实现同时播放相同的视频画面，或者进行相同的照片浏览等功能。
本实施例中，多个手机中已经预先存储有需要展示的多媒体数据。
