下面结合图10a至图10d对本公开实施例提供的上述开关门提醒装置的原理进行详细说明。
一个实施例：
以有日光或者灯光等外界光源的条件下(即图7a和图7b所示的工作原理)为例：
首先在门处于关闭状态时，标定门的位置，如图10a所示，此时两个感光传感器分别位于镂空区和非镂空区，以第二感光传感器041位于非镂空区，第一感光传感器031位于镂空区(反之亦可)为例，此时经外界光源照射，如图7a所示，第二感光传感器041未检测到光光信号(本公开中用代码0表示未检测到光光信号)；如图7b所示，第一感光传感器031检测到光信号(本公开中用代码1表示检测到光信号)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t1，此时刻相应的两个传 感器检测到的光信号的状态如表1所示。
当开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧运动，如图10b所示，第一感光传感器031进入非镂空区，此时由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2大于镂空结构01的宽度w1与第一感光单元组03的宽度d4之和，因此第二感光传感器041仍然位于非镂空区。此时第一感光传感器031和第二感光传感器041均未检测到光信号(信号均为0)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t2，此时刻相应的两个传感器检测到的光信号的状态如表1所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门的转动沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，如图10c所示，第一感光传感器031仍旧在非镂空区，但是由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2小于相邻两个镂空结构01的中心之间的距离s1与第一感光单元组03的宽度d4之差，因此第二感光传感器041进入镂空区，此时第一感光传感器031仍处于非镂空区，因此未检测到光信号(信号代码为0)，第二感光传感器041检测到光信号(信号代码为1)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t3，此时刻相应的两个传感器检测到的光信号的状态如表1所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，如图10d所示，第一感光传感器031进入下一个镂空区，检测到光信号(信号代码为1)。此时由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2大于镂空结构01的宽度w1与第一感光单元组03的宽度d4之和，因此第二感光传感器041仍然位于上一个镂空区，检测到光信号(信 号代码为1)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t4，此时刻相应的两个传感器检测到的光信号的状态如表1所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，第一感光传感器031仍旧在下一个镂空区，第一感光传感器031检测到光信号(信号代码为1)，但由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2小于相邻两个镂空结构01的中心之间的距离s1与第一感光单元组03沿感光单元2滑动方向的宽度d4之差，因此第二感光传感器041进入非镂空区，第二感光传感器041未检测到光信号(信号代码为0)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t5，此时刻相应的两个传感器检测到的光信号的状态如表1所示。此时的第一感光传感器031和第二感光传感器041的状态与图10a中的第一感光传感器031和第二感光传感器041的状态相同，如果继续开门则再次重复图10a到图10d的循环，如果关门则重复图10d到图10a的循环。

另一个实施例：
在以发光二极管为光源的条件下(即图7c和图7d所示的工作原理)为例：
首先在门处于关闭状态时，标定门的位置，如图10a所示，此时两个感光传感器分别位于镂空区和非镂空区，以第二感光传感器041位于非镂空区，第 一感光传感器031位于镂空区(反之亦可)为例，此时发光二极管光源发射光线，如图7c所示，感光单元2凹槽aa与遮光板11的底面的镜面结构形成一个密闭空间，光线(箭头指向)照射到遮光板11的底面的镜面结构被反射到第二感光传感器041，第二感光传感器041检测到光信号，由于第一感光传感器031和第一发光二极管032位于镂空区(如图7d所示)，光线(箭头指向)没有被遮挡，通过镂空区照射到导光板12上发散到外部空间，因此第一感光传感器031没有检测到光信号，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t1，此时刻相应的两个传感器检测到的光信号的状态如表2所示。
当开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧做弧线运动，如图10b所示，第一感光传感器031进入非镂空区，此时由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2大于镂空结构01的宽度w1与第一感光单元组03的宽度d4之和，因此第二感光传感器041仍然位于非镂空区。此时第一感光传感器031和第二感光传感器041均检测到光信号(信号均为1)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t2，此时刻相应的两个传感器检测到的光信号的状态如表2所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，如图10c所示，第一感光传感器031仍旧在非镂空区，但是由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2小于相邻两个镂空结构01的中心之间的距离s1与第一感光单元组03沿感光单元2滑动方向的宽度d4之差，因此第二感光传感器041进入镂空区，此时第一感光传感器031由于处于非镂空区，因此仍然检测到光信号(信号代码为1)，第二感光传感器041由于处于镂空区，因此未检测到光信号(信号代码为0)，图9 中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t3，此时刻相应的两个传感器检测到的光信号的状态如表2所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，如图10d所示，第一感光传感器031进入下一个镂空区，未检测到光信号(信号代码为0)。此时由于图8中所示的，在沿所述圆弧的方向上，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2大于镂空结构01的宽度w1与第一感光单元组03的宽度d4之和，因此第二感光传感器041仍然位于镂空区，未检测到光信号(信号代码为0)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t4，此时刻相应的两个传感器检测到的光信号的状态如表2所示。
继续开门时，本公开中的开关门提醒装置中的感光单元2随着门沿遮光板11的外围镂空区所在的圆弧继续做弧线运动，第一感光传感器031仍旧在镂空区，第一感光传感器031未检测到光信号(信号代码为0)，但由于图8中所示的，第一感光单元组03的中心与第二感光单元组04的中心之间的距离s2小于相邻两个镂空结构01的中心之间的距离s1与第一感光单元组03沿感光单元2滑动方向的宽度d4之差，因此第二感光传感器041进入非镂空区，第二感光传感器041检测到光信号(信号代码为1)，图9中的处理器31记录第一感光传感器031和第二感光传感器041检测到的光信号并记录当前时间t5，此时刻相应的两个传感器检测到的光信号的状态如表2所示。此时的第一感光传感器031和第二感光传感器041的状态恰好与图10a中的第一感光传感器031和第二感光传感器041的状态相同，如果继续开门则再次重复图10a到图10d的循环，如果关门则重复图10d到图10a的循环。

具体实施时，由于本公开实施例提供的开关门提醒装置中遮光板外围区的镂空结构是沿所述圆弧均匀分布的，因此相邻两个镂空结构所对应的角度是固定的，每重复上述一个t1至t4的过程，即门转过一个镂空结构的角度如图10a至图10d所示，再除以这一过程的时间间隔，即可以得到开或关门的速度。
正常情况下，一个人开门的过程换算成门开合的角度和速度可以描述为如下过程：从角度0逐渐增大到角度θ，在这期间，开门的速度从0增加到最大速度ω然后逐渐减小到0。由于个体差异θ、ω会有所不同，但都处于一个正常范围(θ1<θ<θ2，ω1<ω<ω2)内。与开门的过程类似，关门时，门的开合角度从θ减小到0，速度也会从0到ω再到0，速度ω也处在一个范围(ω3<ω<ω4)内。
当处于上述的正常开关门过程时图9中报警器32不会报警提醒，当出现以下等异常时就会报警提醒：
当开门的最大速度小于ω1，并且开合角度θ缓慢的从0增大到小于θ1的一个值，表明此时门被异常打开，有可能是儿童，或体形较小的动物等使门打开。
当开门的最大速度小于ω1，开合角度θ缓慢的从0增大到(θ1，θ2)范围内，然后又以小于ω3的最大速度，开合角度缓慢的减小的0时，表明此时门被人(不知出于何种目的)轻轻的打开又关闭。
当门以正常的情况被打开，在关门的过程中，门的开合角度未减小到0时，又被以正常的速度打开至(θ1，θ2)范围内，表明此时有连续多人通过。
当门以正常速度被打开，但门的开合角度大于θ2，并且处于θ2保持不动时，表明门被人为的固定在某一位置，有可能为了搬运物品等。
当门以大于ω2的最大速度被打开，门的开合角度大于θ2，或者在关门的过程中，关门的速度大于ω4，表明此时门可能被暴力的打开或关闭，有可能对门造成损害。
当出现以上等非正常情况时，图9中报警器32就会以不同的警示声进行报警提示，以防止屋主发生财务损失。
综上所述，本公开通过计算的门开关的角度及速度，可以判断门当前所处的状态，开门中、关门中、缓慢关门中、暴力开关门、门敞开等，然后进行开关门提醒，达到了更加人性化的报警效果。
基于同一发明构思，本公开实施例还提供了一种开关门提醒方法，如图11所示，包括：
S1101、导光单元接收光源的光并将光源发出的光引导向所述感光单元；
S1102、感光单元根据所述导光单元引导的光生成电信号，并将生成的电信号提供给处理单元；
S1103、处理单元根据接收的电信号判断门的开关状态，并根据门的开关状态发出对应的提醒信号。
本公开涉及一种开关门提醒装置及开关门提醒方法，包括：导光单元，感光单元和处理单元，导光单元固定于门框上，感光单元固定于门板上，且导光单元与感光单元在门处于开关状态时保持相互接触，导光单元将光源发出的光引导向感光单元，感光单元将所述导光单元引导的光转换成电信号，并将生成的电信号提供给处理单元；处理单元根据接收的电信号判断门的开关状态，如果是不正常的开关门，处理单元则发出对应的提醒信号，以便屋主实时监控门的开关状态，提高安全防范意识。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
