具体实施方式
下面结合附图，对本公开实施例提供的智能反光调节装置、其调节方法及防眩后视镜的具体实施方式进行详细的说明。
本公开实施例提供了一种智能反光调节装置，如图1所示，可以包括：感光模块1、处理模块2、电源模块3和反光模块4；其中，感光模块1用于将感应到的第一方向的光信号转化为第一电信号，将感应到的第二方向的光信号转化为第二电信号，且将第一电信号和第二电信号输出到处理模块2；处理模块2用于将第一电信号和第二电信号的差值的绝对值与多个预设区间进行匹配，并输出与匹配的预设区间对应的控制信号到电源模块3；电源模块3用于将控制信号转化为电源信号并输出到反光模块4；反光模块4用于在电源信号的控制下，降低反射的光信号的透过率。
本公开实施例提供的上述智能反光调节装置，通过感光模块将感应到的第一方向、第二方向的光信号转化为电信号；通过处理模块将转化的电信号进行计算并与预设区间匹配，并根据匹配结果确定对应的控制信号；电源模块将控制信号转化为电源信号；进而反光模块可以在电源信号的控制下降低反射光的透过率，进而降低反射进入人眼的光的强度，避免产生眩光对人造成伤害。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，处理模块可以具体用于：计算第一电信号与第二电信号的差值的绝对值；设定一个预设阈值，从零到预设阈值划分为N个预设区间；其中，N为正整数；将绝对值与预设区间进行匹配，确定绝对值对 应的预设区间，并输出与预设区间对应的控制信号到电源模块。具体地，设定一个预设阈值M，并将0-M划分为多个预设区间，第一方向、第二方向的光信号对应的电信号的差值的绝对值在不同预设区间则确定出不同的控制信号，不同的控制信号转化为不同的电源信号，从而反光模块可以在不同的电源信号的控制下，不同程度的降低反射光的透过率，在避免产生眩光的同时还可以节能。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，N个预设区间为等分区间，各预设区间的端点值In＝(M/N)*n；其中，M为预设阈值，N为预设区间的个数，n为正整数且不大于N。具体地，如图2所示，光信号与电信号之间具有正比的关系，因此感光模块可以将感应到的光信号转化为电信号，进而处理模块可以对电信号进行数据处理。例如设定预设阈值M为光信号的光通量为15000LUX时对应的电流数据，当然在实际应用时可以根据实际应用条件设定其他的数值，在此不作限定。将0-M分为N个等分区间，等分区间的各端点值In＝(M/N)*n，由小到大分别为I1、I2、I3、I4……In；对应的等分区间为第1预设区间、第2预设区间、第3预设区间……第m预设区间分别为[I1 I2)、[I2 I3)、[I3 I4)……[In-1 In)；处理模块可以计算出第一方向、第二方向的光信号对应的电信号的差值的绝对值，且确定该绝对值位于上述哪一个预设区间内，一个预设区间对应一个控制信号，从而处理模块将确定的预设区间对应的控制信号输出到电源模块，电源模块将控制信号转化为相应的电源信号，从而反光模块可以在电源信号的控制下，降低反射光的透过率，在避免产生眩光的同时还可以节能。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，处理模块还可以用于：确定第一电信号和/或第二电信号大于预设阈值时，输出预设控制信号到电源模块；其中，预设控制信号用于被电源模块转化为预设电源信号并输出到反光模块；确定绝对值小于最小端点值时，输出零电平控制信号到电源模块；其中，零电平控制信号用于关闭电源模块，使得电源模块不输出电源信号到反光模块。具体地，在第一方向、第二方向(例如行驶过程中的前方、后方)的光信号的强度大于预设阈值时，即前、后感应到的光信号中的之一或均大于预设阈值时，则输出预设控制信号到电源模块，电源模块生成对应的预设电源信号并输出到反光模块，控制反光模块开启最大的防眩模式，即将反射光的透过率进行最大程度的降低；在前、后光信号强度对应的电信号的差值的绝对值小于最小的端点值I1时，则输出零电平控制信号到电源模块，此时电源模块不会输出电源信号到反光模块，从而不需要调节反射光的透过率，这样可以实现智能反光调节装置的节能控制。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，处理模块输出到电源模块的控制信号为脉冲信号；脉冲信号的占空比通过如下计算公式获得：Dm＝(m/N)*T；其中，D为脉冲信号的占空比，T为脉冲信号的周期，m为第m个预设区间。具体地，一般的脉冲信号如图3所示，占空比D＝t/T，其中t为高电平持续的时间，T为脉冲信号的周期。本公开实施例提供的智能反光调节装置中的处理模块可以根据匹配结果，即根据第一方向、第二方向的光信号强度对应的电信号的差值的绝对值对应的预设区间，输出对应 占空比的脉冲信号，进而电源模块在相应的占空比的脉冲信号的控制下输出对应的电源信号。例如，将预设阈值M等分为10个等分区间，第一方向、第二方向的光信号强度对应的电信号的差值的绝对值位于第3预设区间，即绝对值大于等于I3且小于I4，则处理模块向电源模块输出的对应脉冲信号D3＝(3/10)*T。
另外，如图4所示，对于预设区间的数量的设定可以通过智能设备与智能反光设备进行无线连接进行设定，例如可将手机通过蓝牙模块与处理模块进行无线连接，进而在手机上相应的应用程序界面进行相关参数的设定，这样可以方便用户通过智能设备自由设定相关参数。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，如图4所示，感光模块可以包括：第一感光传感器11和第二感光传感器12；其中，第一感光传感器11用于将感应到的第一方向的光信号转化为第一电信号且输出到处理模块2；第二感光传感器12用于将感应到的第二方向的光信号转化为第二电信号且输出到处理模块2。具体地，第一感光传感器和第二感光传感器可以通过光敏电阻来实现，如图4所示，第一感光传感器可通过前光敏电阻来实现，第二感光传感器通过后光敏电阻来实现，当然也可以采用其他可以实现光电转换的器件来实现，在此不作限定。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，如图4所示，处理模块2可以为具有数据处理功能的单片机。具体地，单片机可以将光信号转换成的电信号进行数据处理，并输出对应的脉冲控制信号。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，如图4所示，电源模块3可以包括：直流电源Vin、开关晶体管Q、二极管D、电感线圈L、电容C和电阻R；其中，直流电源Vin的正极与开关晶体管Q的源极相连，负极分别与二极管D的正极、电容C的一端和电阻R的一端相连；开关晶体管Q的栅极与处理模块2的输出端相连，漏极分别与二极管D的负极和电感线圈L的一端相连；电感线圈L的另一端分别与电容C的另一端、电阻R的另一端和信号输出端Vout相连；其中信号输出端Vout用于向反光模块4输入电源信号。具体地，电源模块为一个开关电源电路，其相应的结构与工作原理与现有技术相同，电源模块输出的电源信号Vout＝Vin*Dm，即电源模块对应处理模块输出的不同占空比的脉冲信号，可以对应输出不同的电源信号，最终反光模块在不同电源信号的控制下，不同程度的降低反射光的透过率，从而可以实现防眩光和节能相结合。
在具体实施时，本公开实施例提供的上述智能反光调节装置中，如图5所示，反光模块可以包括：第一玻璃基板G1、第一透明电极层T1、电致变色层EL、第二透明电极层T2和第二玻璃基板G2；其中，电致变色层EL随着施加的电源信号增大透过率越低。具体地，电致变色层的电致变色材料在电源闭合即施加电信号的情况下会触发氧化还原反应，从而产生变色的现象；当电源断开时，反应可逆变化，电致变色材料恢复到透明状态。如图6所示，电源闭合时，即通过第一透明电极层和第二透明电极层对电致变色层施加电信号时，离子库导体P中的离子向电致变色材料所在的区域移动，使得电致变色材料发生 变色现象，从而影响电致变色层的透过率，需要说明的是电致变色层的结构中还包括离子导体A和电解液B，其相应的结构和功能与现有技术相同，在此不作详述。这样针对电致变色层的变色调节，随着施加的电源信号的强弱，电致变色层相应的会发生颜色的变化，对应的发生透过率的变化，进而通过调节电源模块输入到反光模块的电源信号，可以实现防眩的功能。
基于同一发明构思，本公开实施例提供了一种防眩后视镜，包括本公开实施例提供的上述智能反光调节装置。具体地，可以将智能反光装置集成于汽车的后视镜，根据前车、后车(对应第一方向、第二方向)照在后视镜上的光线强弱来控制反射光的透过率，达到防眩与显示相结合的同时，还可以节约能源。

在具体实施时，本公开实施例提供的上述调节方法中，步骤S102可以具体包括：计算第一电信号与第二电信号的差值的绝对值；设定一个预设阈值，从零到预设阈值划分为N个预设区间；其中，N为正整数；将绝对值与预设区间进行匹配，确定绝对值对应的预设区间，并输出与预设区间对应的控制信号。具体地，可以将预设阈值划分为多个预设区间，从而根据确定的第一方向、第二方向的光信号对应的电信号的差值的绝对值所位于的不同预设区间，输出对应的控制信号，对应的控制信号产生对应的电源信号，进而反光模块对应不同的电源信号，可以不同幅度降低反射光的透过率，既能达到防眩的目的，又可以节省能源。
在具体实施时，本公开实施例提供的上述调节方法中，N个预设区间为等分区间，各预设区间的端点值In＝(M/N)*n；其中，M为预设阈值，N为预设区间的个数，n为正整数。具体地，可以将将0-M分为N个等分区间，等分区间的各端点值In＝(M/N)*n，由小到大分别为I1、I2、I3、I4……In；对应的等分区间为第1预设区间、第2预设区间、第3预设区间……第m预设区间分别为[I1 I2)、[I2 I3)、[I3 I4)……[In-1 In)，这样计算 出第一方向、第二方向的光信号对应的电信号的差值的绝对值，且确定该绝对值位于上述哪一个预设区间内，一个预设区间对应一个控制信号，从而将确定的预设区间对应的控制信号输出，且将控制信号转化为相应的电源信号，在电源信号的控制下，降低反射光的透过率，在避免产生眩光的同时还可以节能。
在具体实施时，本公开实施例提供的上述调节方法中，还可以包括：确定第一电信号和/或第二电信号大于预设阈值时，输出预设控制信号；其中，预设控制信号用于被电源模块转化为预设电源信号并输出到反光模块；确定绝对值小于最小端点值时，输出零电平控制信号；其中，零电平控制信号用于关闭电源模块，使得电源模块不输出电源信号到反光模块。具体地，在第一方向、第二方向(例如行驶过程中的前方、后方)的信号的强度大于预设阈值时，即前、后感应到的光信号中的之一或均大于预设阈值时，则输出预设控制信号，根据预设控制信号生成对应的预设电源信号，进而开启最大的防眩模式，即将反射光的透过率进行最大程度的降低；在前、后光信号强度对应的电信号的差值的绝对值小于最小的端点值I1时，则输出零电平控制信号到电源模块，从而不需要调节反射光的透过率，这样可以实现智能反光调节装置的节能控制。
具体地，本公开实施例提供的上述智能反光调节装置的调节过程可以如图8所示，具体过程如下：
S201、将感应到的第一方向和第二方向的光信号分别转换成第一电信号和第二电信号；

S205、输出零电平控制信号，防眩模式不开启；
S206、确定第一电信号与第二电信号的差值的绝对值位于的预设区间，并根据确定的预设区间输出对应的控制信号，将控制信号转化为电源信号，在电源信号的控制下降低反射光的透过率。
在具体实施时，本公开实施例提供的上述调节方法中，控制信号为脉冲信号；脉冲信号的占空比通过如下计算公式获得：Dm＝(m/N)*T；其中，Dm为脉冲信号的占空比，T为脉冲信号的周期，m为第每个预设区间。具体地，根据确定的第一方向、第二方向的光信号强度对应的电信号的差值的绝对值对应的预设区间，输出对应占空比的脉冲信号，进而在相应的占空比的脉冲信号的控制下输出对应的电源信号，在电源信号的控制下即可对应降低反射光的透光率，实现防眩的功能。
