图3是本发明一种手机蓝牙控制的智能汽车天幕系统的结构示意图。
其中，1-天幕基材玻璃，2-隔热杂化覆膜，3-调光片。
具体实施方式
以下根据附图1-3对本发明做进一步说明：
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。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安 装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1所示，本发明第一实施例在现有技术的基础上提供了一种基于光阀技术的车机控制汽车天幕系统，其包括天幕基材玻璃1、隔热杂化覆膜2、调光片3、中央控制器、汽车T-BOX、手机和云后台，接下来将详细介绍一下上述组件的结构以及相互之间的连接关系。
首先介绍一下天幕基材玻璃1，目前天幕基材玻璃1有两种结构包括：双层夹胶钢化玻璃和单层钢化玻璃，四周均与其车顶棚钣金即内饰搭接，但其面积更大，左右可直接与汽车侧围连接，前后可直接与连接A柱C柱的顶棚钣金搭接，隔热杂化覆膜2贴合在天幕基材玻璃1外侧，隔热杂化覆膜2吸收80％以上的红外线并反射99％以上的紫外线，具有优秀的隔热效果，无需遮阳帘即可实现避免大尺寸玻璃导致的车内温度过高问题。
当天幕基材玻璃1为单层钢化玻璃结构时，调光片3采用LC调光玻璃，如图2所示，LC调光玻璃贴合在天幕基材玻璃1内侧，LC调光玻璃与天幕基材玻璃1随型，当天幕基材玻璃1为双层夹胶钢化玻璃结构时，调光片3可采用PDLC调光片、LV调光片和EC调光片，由于三种膜片与天幕基材玻璃1配合的结构均相同，如图3所示，以PDLC调光片为例详细说明，PDLC调光片安装在天幕基材玻璃1的双层玻璃夹层内，PDLC调光片与天幕基材玻璃1随型。
汽车T-BOX车载T-BOX主要用于和后台系统/手机APP通信，实现手机APP的车辆信息显示与控制。当用户通过手机端APP发送控制命令后，TSP后台会发出监控请求指令到车载T-BOX，车辆在获取到控制命令后，通过CAN总线发送控制报文并实现对车辆的控制，最后反馈操作结果到用户的手机APP上。本实施例汽车T-BOX与手机汽车天幕app分别通过云后台模块通过无线网络进行 数据通信，手机汽车天幕app上均设有设置界面，所述设置界面上均设有虚拟开关以及面板，所述虚拟开关用于开启/关闭自动关闭调光片，所述面板用于设置调光片的透光度参数。
中央控制器中央控制器以通用计算设备的形式表现，通常，计算设备包括有：处理器和存储器。
处理器可以包括一个或多个处理核心，比如4核心处理器、8核心处理器等。处理器可以采用DSP(Digital Signal Processing，数字信号处理)、FPGA(Field－Programmable Gate Array，现场可编程门阵列)、PLA(Programmable Logic Array，可编程逻辑阵列)中的至少一种硬件形式来实现。处理器也可以包括主处理器和协处理器，主处理器是用于对在唤醒状态下的数据进行处理的处理器，也称CPU(Central Processing Unit，中央处理器)；协处理器是用于对在待机状态下的数据进行处理的低功耗处理器。在一些实施例中，处理器可以在集成有GPU(Graphics Processing Unit，图像处理器)，GPU用于负责显示屏所需要显示的内容的渲染和绘制。一些实施例中，处理器101还可以包括AI(Artificial Intelligence，人工智能)处理器，该AI处理器用于处理有关机器学习的计算操作。
存储器可以包括一个或多个计算机可读存储介质，该计算机可读存储介质可以是有形的和非暂态的。存储器还可包括高速随机存取存储器，以及非易失性存储器，比如一个或多个磁盘存储设备、闪存存储设备。调光片3与中央控制器电性连接，中央控制器通过CAN/LIN总线与汽车T-BOX电性连接。
上面介绍完一种基于光阀技术的车机控制汽车天幕系统，下面将介绍其控制方法，具体步骤包括：
云后台接收到手机汽车天幕app发送的调光请求时，获取调光请求中的调光数据并发送给汽车T-BOX；
汽车T-BOX接收到调光数据后发送给中央控制器；
中央控制器接收到调光数据后生成调光指令发送给调光片3；
调光片3接收到调光指令后执行所述调光请求中的调光操作。
调光片3的不同对应不同的调光操作：
当调光片3为LV调光片3时，通过控制串联电阻改变大小来改变LV调光膜片3两端电极之间的电压，在高电压下光阀排列顺序发生改变，致使膜片透光度改变。
当调光片3为PDLC调光片时，通过控制PDLC调光片两端电极的电压大小及方向来改变液晶分子周围电场，进而改变液晶分子排列方式进而改变玻璃透光度。
当调光片3为EC调光片时，通过控制EC调光片两端电极施加对应方向的电压而产生正向或反向的电流，膜片内物质在电流作用下发生氧化还原反应。
当调光片3为LC调光玻璃时，在LC调光玻璃3电极两端施加电压，玻璃为透明色；在LC调光玻璃3电极两端不施加电压时则形成断路，玻璃两端电极无电压，则玻璃为黑色。
尽管本发明的实施方案已公开如上，但其并不仅仅限于说明书和实施方式中所列运用。它完全可以被适用于各种适合本发明的领域。对于熟悉本领域的人员而言，可容易地实现另外的修改。因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
