具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
图1是根据本发明一个实施例的颜色传感器模组的示意性结构图。一种颜色传感器模组1用于识别其对应的目标场景区域是否有人的存在，一般性地可以包括：光线获取模块10、信号接收转换及处理模块20和判断模块30。光线获取模块10用于汇聚与所述颜色传感器模组1对应的目标场景区域内的当前光线。通常目标场景区域与照明区域重合，光线获取模块10汇聚的是反射后的光线。信号接收转换及处理模块20用于接收所述光线获取单元汇聚的所述当前光线的光信号，将所述光信号转化为电信号并调制为所述当前光线对应的R、G、B通道数值，并将所述R、G、B通道数值换算为颜色空间的色点坐标(x，y)输出。颜色空间是根据CIE1931标准色度空间确定的，光线的RGB三色各分量的强度数据转换为CIE标准三色值X、Y、Z，并根据所述CIE标准三色值X、Y、Z计算出光线的色坐标(x,y)。判断模块30用于接收所述信号接收转换及处理模块20前后两次输出的色点坐标(x，y)并判定它们之间是否存在变化。其中，根据色点坐标(x，y)是否存在变化判断人的存在。
需要说明的是，本实施例中所述的前后两次色点坐标(x，y)可以是前后相邻两次的色点坐标(x，y)，还可以是中间隔一定时间的前后两次的色点坐标(x，y)，还可以是中间隔一定次数的前后两次的色点坐标(x，y)。
更具体地，本实施例中，所述判断模块30配置为比较接收到的时间点在后的第二色点坐标(x2，y2)与时间点在前的第一色点坐标(x1，y1)的x向差值、y向差值或坐标点的绝对距离值，在所述x向差值、所述y向差值或所述坐标点的绝对距离值超过设定的第一阈值时，判定为所述目标场景区域内有人存在。
其中，x向差值、y向差值为及坐标点的绝对距离值的计算公式如下：
Δx＝x2-x1；
Δy＝y2-y1；
Figure PCTCN2018092443-appb-000001
式中：
Δx表示x向差值；
x1表示时间点在前的第一色点的x向坐标值；
x2表示时间点在后的第二色点的x向坐标值；
Δy表示y向差值；
y1表示时间点在前的第一色点的y向坐标值；
y2表示时间点在后的第二色点的y向坐标值；
dxy表示时间点在后的第二色点坐标点与时间点在前的第一色点的坐标点的绝对距离值。
定义，第一阈值为A。
如果Δx>A，或
Δy>A，或
dxy>A时，
则引起了色点突变，可以判定有人进入目标区域场景。
在上述三个变量中具体采用哪一个来进行判断，根据使用环境的不同是可选的。例如，在办公环境中，选择变量x为判断基准，在Δx>A时，判定为有人进入目标场景。例如，在家的环境中，选择变量y为判断基准，在Δy>A时，判定有人进入目标场景。在某些场合，同时选择两个变量，如选择变量x和变量dxy为判断基准，当Δx或dxy两个值中任一项值大于A时，判定有人进入目标场景。
本发明所述的颜色传感器模组1，通过采集目标场景区域内的光线，来分析目标场景区域的颜色变化，即分析色点坐标变化，进而辨别目标场景区域是否存在人，从而控制照明设备的开启、关闭或调光调色。其中，调色调光是根据所述色点坐标(x，y)的变化及在CIE图上的变化方向来确定所述照明设备的调光调色方向及目标点。可见，使用所述颜色传感器模组1不但能够控制照明设备的启闭，而且还实现了对照明光线的调节。由于颜色传感器模组1具有灵敏度高、识别准确的特点，因此有效避免了误触发信号的情况，使得本发明可靠性更高。
图2是根据本发明另一个实施例的颜色传感器模组的示意性结构图。本实施例中，所述信号接收转换及处理模块20可以包括时间单元25，用于获取所述当前光线的时间数据；其中，所述信号接收转换及处理模块20配置成将所述时间数据与所述当前光线的色点坐标(x，y)一起输出至所述判断模块30；所述判断模块30配置为比较接收到的时间点在后的第二色点坐标(x2，y2)与时间点在前的第一色点坐标(x1，y1)的色点坐标差值，并将所述x向差值、所述y向差值或所述坐标点的绝对距离值除以所述时间点在后的第二色点坐标(x2，y2)对应的第二时间与所述时间点在前的第一色点坐标(x1，y1)对应的第一时间的时间差值获得比值，在所述比值超过设定的第二阈值时，判定为所述目标场景区域内有人存在。
定义，时间点在后的第二色点坐标为(x2，y2)其对应时间为T1，时间点在前的第一色点坐标为(x1，y1)其对应时间为T0，第二阈值为B。
如果Δx/(T1-T0)>B，或
Δy/(T1-T0)>B，或
dxy/(T1-T0)>B，
引起了色点突变，可以判定有人进入目标区域场景。
在上述三个变量中具体采用哪一个来进行判断，根据使用环境的不同是可选的。例如，在办公环境中，选择变量x为判断基准，在Δx/(T1-T0)>B时，判定为有人进入目标场景。例如，在家的环境中，选择变量y为判断基准，在Δy/(T1-T0)>B时，判定有人进入目标场景。在某些场合，同时选择两个变量，如选择变量x和变量dxy为判断基准，当两个值中任一项值大于B时，判定有人进入目标场景。
假设目标场景检测的是早晨到中午的时段，这个时段内一直无人进入目标场景，而由于环境变化早晨到中午，汇聚到的光线会变化，相应地会引起 色点的突变，这种情况不应当开启照明设备。本实施例中引入时间的概念后，就去除了这种环境缓慢变化的因素。只有当人进入这种突变性的活动后，才能引起颜色传感器模组1数值的变化突然，此时认为是有人进来了。
如图2所示，本实施例中，所述信号接收转换及处理模块20可以包括：信号接收单元21、光电转换单元22、信号处理单元23和微处理器24。信号接收单元21用于接收所述当前光线。光电转换单元22用于将所述当前光线的光信号转换为电信号。信号处理单元23用于处理所述电信号。微处理器24用于调制出所述当前光线的R、G、B通道数值，并将其转换为色点坐标(x，y)输出。
图3根据本发明另一个实施例的颜色传感器模组的示意性透视图。具体实施时，所述光线获取模块10可以为光学元件，例如光学透镜，当然还可以是其他光学元件。所述颜色传感器模组1还可以包括外壳50，用于容置并保护所述光线获取模块10、所述信号接收转换及处理模块20及所述判断模块。本实施例中，所述外壳50包括：上盖51及后盖52。上盖51用于安装及固定所述光线获取模块10，并保护所述信号接收转换及处理模块20以及所述判断模块。其中，所述信号接收转换及处理模块20以及所述判断模块可以是集成的电路板40。电路板40中可以具有供电接口、数据输出接口及调试接口。供电接口用于为颜色传感器模组1进行供电。数据输出接口用于将接收到的光信号经过转化后输出调制数据。调试接口用于更新内置嵌入式程序。后盖52用于安装及固定所述信号接收转换及处理模块20及所述判断模块，与所述上盖51固定连接，其后端面设有固定件53，用于所述颜色传感器模组1的安装。更进一步地，所述颜色传感器模组1还包括连接器60，用于与照明装置对接。
图4是根据本发明一个实施例的智能照明装置的示意性结构图。本发明还提供了一种智能照明装置I，可以包括上述实施例中所述的颜色传感器模组1和照明设备3，所述照明设备3包括用于控制其开启、关闭或调色调光的驱动控制器2，所述颜色传感器模组1与所述驱动控制器2信号连接，所述驱动控制器2配置成根据所述颜色传感器模组1的判断模块30的判断结果控制所述照明设备3的开启、关闭或调光调色。
本发明所述的智能照明装置I，通过颜色传感器模组1采集目标场景区域内的光线，来分析目标场景区域的颜色变化，即分析色点坐标变化，进而辨别目标场景区域是否存在人，从而控制照明设备3的开启、关闭或调光调 色。可见，本发明不但能够控制照明设备3的启闭，而且还实现了对照明光线的调节。由于颜色传感器模组1具有灵敏度高、识别准确的特点，因此有效避免了误触发信号的情况，使得本发明所述的智能照明装置I可靠性更高。
如图4所示，本实施例中，所述驱动控制器2还包括延时单元2A，所述延时单元2A用于在所述驱动控制器2控制所述照明设备3开启后，控制所述照明设备3持续照明预定时间。预定时间可以是5分钟。在所述照明设备3达到所述预定时间5分钟，由所述颜色传感器模组1的判断模块30判断为色点坐标(x，y)是否变化，色点坐标(x，y)有变化再持续照明预定时间5分钟。直至在所述照明设备3达到所述预定时间5分钟且所述颜色传感器模组1的判断模块30判断为没有色点坐标(x，y)变化时，所述驱动控制器2控制所述照明设备3关闭。
本实施例中，在照明设备3开启后增加了延时，使得用户的体验更好。例如目标场景区域中的人有动作，例如踱步，颜色传感器模组1会判断出色点存在漂移，即色点坐标(x，y)有变化，照明装置延时照明5分钟。之后有第二人进入目标场景区域，经判断色点坐标(x，y)有变化，照明装置再延时照明5分钟。重复上述判断并执行相应动作，直至，达到预定时间且判断色点坐标(x，y)没有新的变化，则认为目标场景区域中没有人了，然后关闭照明设备3。

S100，汇聚目标场景区域内的当前光线；
S200，接收所述当前光线的光信号，将所述光信号转化为电信号并调制为所述当前光线对应的R、G、B通道数值，并将所述R、G、B通道数值换算为颜色空间的色点坐标(x，y)；
S300，根据接收到的前后两次的色点坐标(x，y)判定它们之间是否存在变化，其中，所述的前后两次色点坐标(x，y)可以是前后相邻两次的色点坐标(x，y)，还可以是中间隔一定时间的前后两次的色点坐标(x，y)，还可以是中间隔一定次数的前后两次的色点坐标(x，y)；
S400，根据色点坐标(x，y)变化调整照明设备3(参见图4)的开启、关闭或调色调光。
本实施例中，S400中所述照明设备3的调色调光是根据所述色点坐标(x，y)的变化及在CIE图上的变化方向来确定所述照明设备3的调光调色方向及 目标点。

dxy表示时间点在后的第二色点坐标点与时间点在前的第一色点的坐标点的绝对距离值。
定义，第一阈值为A。
如果Δx>A，或
Δy>A，或
dxy>A时，
则引起了色点突变，可以判定有人进入目标区域场景，此时开启照明设备3。
在上述三个变量中具体采用哪一个来进行判断，根据使用环境的不同是可选的。例如，在办公环境中，选择变量x为判断基准，在Δx>A时，判定为有人进入目标场景。例如，在家的环境中，选择变量y为判断基准，在Δy>A时，判定有人进入目标场景。在某些场合，同时选择两个变量，如选择变量x和变量dxy为判断基准，当Δx或dxy两个值中任一项值大于A时，判定有人进入目标场景。
本实施例中，所述接收所述当前光线的光信号，还包括获取所述当前光线的时间数据；
将所述时间数据与所述当前光线的色点坐标(x，y)一起输出；
比较接收到的时间点在后的第二色点坐标(x2，y2)与时间点在前的第一色点坐标(x1，y1)的x向差值、y向差值或坐标点的绝对距离值，并将所述x向差值、所述y向差值及所述坐标点的绝对距离值除以所述时间点在后的第二色点坐标(x2，y2)对应的第二时间与所述时间点在前的第一色点坐标(x1，y1)对应的第一时间的时间差值获得比值，在所比值超过设定的第二阈值时，调整所述照明设备3开启。
定义，时间点在后的第二色点坐标为(x2，y2)其对应时间为T1，时间点在前的第一色点坐标为(x1，y1)其对应时间为T0，第二阈值为B。
如果Δx/(T1-T0)>B，或

  12. 根据权利要求11所述的智能照明控制方法，其中，所述根据色点坐标(x，y)变化调整照明设备开启是：比较接收到的时间点在后的第二色点坐标(x2，y2)与时间点在前的第一色点坐标(x1，y1)的色点的x向差值、y向差值或坐标点的绝对距离值，在所述x向差值、所述y向差值或所述坐标点的绝对距离值超过设定的第一阈值时，调整所述照明设备开启。
  13. 根据权利要求11所述的智能照明控制方法，其中，所述接收所述当前光线的光信号，还包括获取所述当前光线的时间数据；
    将所述时间数据与所述当前光线的色点坐标(x，y)一起输出；
    比较接收到的时间点在后的第二色点坐标(x2，y2)与时间点在前的第一色点坐标(x1，y1)的x向差值、y向差值及坐标点的绝对距离值，并将所述x向差值、所述y向差值及所述坐标点的绝对距离值除以所述时间点在后的第二色点坐标(x2，y2)对应的第二时间与所述时间点在前的第一色点坐标(x1，y1)对应的第一时间的时间差值获得比值，在所述比值超过设定的第二阈值时，调整所述照明设备开启。
  14. 根据权利要求12或13所述的智能照明控制方法，其中，还包括在 所述照明设备开启后，控制所述照明设备持续照明预定时间；
    在所述照明设备达到所述预定时间且经判断为有色点坐标(x，y)变化时，所述照明设备持续照明所述预定时间；
    在所述照明设备达到所述预定时间且经判断为没有色点坐标(x，y)变化时，所述照明设备关闭。
  15. 根据权利要求11-14中任一项所述的智能照明控制方法，其中，所述照明设备的调色调光是根据所述色点坐标(x，y)的变化及在CIE图上的变化方向来确定所述照明设备的调光调色方向及目标点。
