具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。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特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
在本实施例中提供了一种投影仪，本发明实施例投影仪在天线阵列板的侧边加驱动结构，驱动动力来自于手动调整支撑轴转动或马达驱动支撑轴转动。这样当投影仪用于背投、吊装、桌面常态和桌面异态等各种应用场景时，就能通过手动调节或系统自适应调节实现对天线阵列板的位置和 /或者指向的调整变更，以适应新的应用场景，确保无线HDMI传输的质量。
图2是根据本发明实施例的投影仪结构图，如图2所示，该投影仪包括投影本体和用于接收待投影信号的天线阵列板，天线阵列板的位置和/或指向是活动的。
通过上述结构，可以实现对调整天线阵列板位置和/或指向的调整，以适应新的应用场景，确保传输的质量，解决了相关技术中天线阵列板位置和/或指向固定，导致的投影效果差的问题，达到了提高投影质量的效果。
图3是根据本发明实施例的投影仪的优选结构图一，图4是根据本发明实施例的投影仪的优选结构图二，在实际应用中，如图3和图4所示，上述天线阵列板可以安装在投影仪的无线高清晰度多媒体接口(High Definition Multimedia Interface，简称为HDMI)接收模块上。
天线阵列板的位置和/或指向是活动的可以通过多种方式实现，例如，可以将上述天线阵列板固定在支撑轴上，通过转动支撑轴来改变天线阵列板的位置和/或指向。通过上述结构，可以减少转动过程的摩擦，从而减小磨损，防止老化。
通过转动支撑轴来改变天线阵列板的位置和/或指向时，可以直接通过移动支撑轴来实现对天线阵列板的移动，从而改变天线阵列板的位置和/或指向；可选地，也可以通过安装驱动装置对天线阵列板的运动来实现天线阵列板的位置和/或指向的改变。例如，可以将支撑轴的轴端嵌入在投影本体的滚动轴承孔中，通过支撑轴相对于投影本体的转动来改变天线阵列板的位置和/或指向。通过上述结构，不仅使得位置和/或指向的改变方便快速，而且可以有效减少转动过程的摩擦，有效防止摩擦生热带来的危害。
在实际应用中，如图3和图4所示，上述支承轴可以安装在固定支架。具体的，安装有天线阵列板的无线HDMI接收模块固定在固定支架上，固定支架的中心安装有支承轴1(轴端嵌入在投影仪壳体(也可以嵌入在投影仪中的内部结构)的滚动轴承孔中)，无线HDMI接收模块的另一端还 安装有支承轴2，以防止无线HDMI接收模块较重时，支承轴1无法支撑无线HDMI接收模块。
可选地，上述投影仪还包括：驱动结构，连接支撑部，用于驱动支撑轴转动。其中，该驱动结构可以采用多种方式来实现，下面举例说明。
例如，该驱动结构可以包括：马达，传送带和转轮，其中，转轮安装在支撑轴上，通过驱动马达使传送带带动转轮旋转以带动支撑轴转动。通过上述结构，可以灵活的自适应调整天线阵列板的位置和/或指向到目标位置和/或指向。
在实际应用中，如图3所示，可以在固定支架偏一端位置安装非金属转轮，由距离一定距离之外的内含金属成分的步进马达的转轮经非金属传送带带动旋转。马达旋转带动固定支架转动，从而天线阵列板跟随旋转。把确定的步进马达步进值与特定应用场景下所需值进行一一对应，并记录在系统软件中，主处理器经马达控制线传递步进值到马达，就可以使得投影仪不同应用场景下的天线阵列板位置和朝向得到有效控制。
又例如，该驱动结构还可以包括：马达，卡簧和滚轴丝杠，其中，卡簧安装在支撑轴上且卡簧与滚轴丝杠固定连接，滚轴丝杠以螺纹连接的方式与马达连接，通过驱动马达使滚轴丝杠带动卡簧以带动支撑轴转动。可以快速的自适应调整天线阵列板的位置和/或指向到目标位置和/或指向。
在实际应用中，如图4所示，可以在固定支架偏一端位置安装非金属卡簧，由距离一定距离之外的内含金属成分的步进马达其中心轴上套装(以螺纹连接的方式)的非金属密螺纹滚轴丝杠传动前进和后退力量，通过卡簧带动固定支架和电路子板位移。
又例如，上述驱动结构可以采用调节转轮替代马达，其中，调节转轮用于接收物理外力驱动以带动支撑轴转动。可以直观的调整天线阵列板的位置和/或指向到目标位置和/或指向。
在实际应用中，可以在手动调节模式下驱动支撑轴转动，手动调节模式可以不需要马达，对有限的如背投、吊装模式，直接给出调节转轮的固 定位置指向，用户把调节转轮调到指示位置即可。
可选地，上述支撑轴，转轮，传送带，滚轴丝杠和卡簧可以为非金属材料。上述投影仪中靠近天线阵列板的结构采用非金属结构材料可以减少对无线高清阵列天线带来的干扰。同时，可以使得天线阵列板调整到不同指向、任意位置时，均不受金属层阻隔干扰。
实施例2
本申请实施例二所提供的方法实施例可以在投影仪或者类似的运算装置中执行。以运行在投影仪上为例，图5是本发明实施例的一种投影方法的投影仪的硬件结构框图。如图5所示，投影仪50可以包括一个或多个(图中仅示出一个)处理器502(处理器502可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、设置为存储数据的存储器504、以及设置为通信功能的传输装置506。本领域普通技术人员可以理解，图5所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，投影仪50还可包括比图5中所示更多或者更少的组件，或者具有与图5所示不同的配置。
存储器504可设置为存储应用软件的软件程序以及模块，如本发明实施例中的投影方法对应的程序指令/模块，处理器502通过运行存储在存储器504内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器504可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器504可进一步包括相对于处理器502远程设置的存储器，这些远程存储器可以通过网络连接至移动终端50。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置506设置为经由一个网络接收或者发送数据。上述的网络具体实例可包括投影仪50的通信供应商提供的无线网络。在一个实例中，传输装置506包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例 中，传输装置506可以为射频(Radio Frequency，RF)模块，其设置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述投影仪的投影方法，图6是根据本发明实施例的投影方法的流程图，如图6所示，该流程包括如下步骤：
步骤S602，接收待投影信号，其中，接收待投影信号的天线阵列板的位置和/或指向是活动的；
步骤S604，投影待投影信号。
通过上述步骤，可以实现对调整天线阵列板位置和/或指向的调整，以适应新的应用场景，确保传输的待投影信号质量，解决了相关技术中天线阵列板位置和/或指向固定，导致的投影效果差的问题，达到了提高投影质量的效果。
可选地，接收待投影信号可以包括：接收用于控制天线阵列板的位置和/或指向的控制指令；根据控制指令调整天线阵列板的位置和/或指向；根据调整后的天线阵列板的位置和/或指向接收待投影信号。通过上述步骤，调整天线阵列板位置和/或指向到最适应新应用场景的位置和/或指向，使得接收到的待投影信号的质量得到有效地提高。
可选地，在接收待投影信号之前，可以包括：存储应用场景状态值与应用场景状态值对应的马达步进值在存储器中。
可选地，根据控制指令调整天线阵列板的位置和/或指向可以包括多种例如，可以包括系统自适应模式，手动模式等。
系统自适应模式下，调节天线阵列板位置和/或指向通过软件方式实现。在投影仪背投、吊装、桌面异态等不同于缺省的桌面常态放置应用时，软件会基于基本应用模式有一系列的诸如投影镜像、投影倒置等处理流程，在这些流程的入口通过读取应用模式状态值或代替符号值，驱动马达推动天线阵列板转动到预设的经验位置点，使得天线阵列指向处于该应用模式的适宜方向，具体流程分清零算法和非清零算法：
1)清零算法
图7是根据本发明实施例的投影方法的自适应控制天线阵列板位置和/或指向的清零算法流程图，如图7所示，步骤S702，获取投影仪当前使用场景的状态值；步骤S704，对马达步进值进行清零归位；步骤S706，根据状态值调取存储器中对应的马达步进值；步骤S708，根据马达步进值驱动马达推动天线阵列板到达目标位置和/或指向。
通过上述步骤，由于进行了清零操作，因此，无需考虑马达当前步进值，可以根据调用的马达步进值直接驱动马达推动天线阵列板到达目标位置和/或指向。
2)非清零算法
图8是根据本发明实施例的投影方法的自适应控制天线阵列板位置和/或指向的非清零算法流程图，如图8所示，步骤S802，获取投影仪当前使用场景的状态值和当前使用场景之前的前状态值；步骤S804，根据当前状态值和前状态值分别调取当前状态值对应的马达步进值和前状态值对应的马达步进值；步骤S806，计算当前状态值和前状态值对应的马达步进值的差值；步骤S808，根据差值驱动马达推动天线阵列板到达目标位置和/或指向。
通过上述步骤，可以在马达当前的步进值基础上，驱动马达推动天线阵列板到达目标位置和/或指向。
手动调节模式下，接收物理外力驱动天线阵列板到达目标位置和/或指向。手动调节模式可以不需要马达，对有限的如背投、吊装模式，直接给出调节转轮的固定位置指向，用户把调节转轮调到指示位置即可。
通过上述步骤，可以直观的调整天线阵列板的位置和/或指向到目标位置和/或指向。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可 以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
